More than one point forming
Multi-point forming technology for sheet metal forming three-dimensional surface of
a flexible manufacturing method, the basic idea is the overall mold of traditional
discrete ordered into a series of Guize, height-adjustable basic body (or red head). In
the overall die forming, the sheet from the mold surface to shape and multi-point
forming the basic body by the group (or punch group) posed by the envelope (or
forming surface) to complete. Multi-point forming the basic body of each stroke can
be adjusted separately to change the location of the basic body shape to change the
surface, thus re-construct the equivalent of the forming die, thus reflects the
characteristics of multi-point forming flexible. The technology utilizes a flexible
multi-point forming equipment, the characteristics of mold can be carried out without
the need for different parts of the forming three-dimensional surfaces, and multi-point
forming technology uses computer-aided design, manufacturing and supporting
ancillary testing technology, flexible manufacturing technology and computer
technology to one, in order to achieve no mold, rapid digital manufacturing.
Compared to the traditional mold forming method, Duo-point forming machine to
achieve a multi- Yong's vision, can save mold design and manufacturing
requirements of a lot of time and Fei Yong, can significantly red uce product costs, Jia
Su product upgrading, Shi Ying small volume production requirements. Multi-point
forming of sheet metal can be used in shipbuilding, automotive, medical engineering,
building large industries.
Two sub- multi-point forming technology
The whole forming section forming relatively speaking, is when the job's
rough outline of the effective size of the forming size larger than when forming
equipment used to suppress the forming section method. In sub- multi-point forming,
the large size of some part of the plate to be suppressed, when the plate is forming
part of, the multi-point mode shape will be adjusted, and then with the sheet forming
the feed in sequence to the rest.
Sub-emergence of multi-point forming technology for large panel processing opened
up a new path. This technology can be implemented on a smaller device processing
large panels, which can greatly reduce the equipment tonnage, full use of existing
equipment and new equipment to save huge expenditure. And because each section
forming part of the workpiece without separation, it is cold forming, can guarantee the
performance of plate. So for large sheet metal forming, sub-way multi-point forming
very clear advantages. Piecewise multi-point forming technology can be formed in the
past had to be done manually by the large size workpiece.
3 Machine
Metal cutting machine tools is the way the metal cutting process into a rough part of
the process machinery and equipment. It provides tool and relative motion between
the workpiece and provide the necessary processing power and economic completion
of certain mechanical processes. Machine tool quality and performance of the
processing machinery directly affect the quality and scope of the economic process,
but it is always with raising the level of mechanical industrial processes and scientific
and technological progress and development. Extensive use of metal cutting machine
tools of modern mechanical, electrical, electronic, hydraulic, pneumatic devices to
achieve movement and circulation. Machine by the drive unit, duty cycle institutions,
supporting institutions and control systems combined together to form a unified
complex process. Function of metal-cutting machine tools, structure, size and
accuracy are all kinds of, the nature of the process used by the different tools can be
divided into: lathes, drilling, boring, grinding, gear cutting machines, screw machines,
milling machine, planer, slotting, broaching machine, special machine tools, sawing
and other machines. Divided according to degree of commonality: common tool that
is universal machine tools, specialized machine tools, special machine. Weight
divided by machine: light machine tools, medium machine tools, heavy machine tools.
Divided into general accuracy by precision level, precision and ultra precision
machine tool level. Divided by automated manual, motorized, semi-automatic and
automatic machines.
CNC machine tools is the use of digital information control machine tools. League of
the Fifth International Information Processing Technical Committee made the
following definition of CNC Machines: CNC machine is a machine tool with
numerical control system, the system can use logic to deal with numbers, or other
symbol coding procedures provided instructions. Modern CNC machine tools is
developed, and has broad prospects for development of new automation tools, is a
highly integrated mechanical and electrical products. It solves the complex shape,
high precision, small volume production and short production cycle, and products
change frequently and more varieties of low-volume product manufacturing problems,
is a flexible and efficient automatic machine tools, is a computer aided design and
manufacturing (CAD / CAM), group control (DNC), flexible manufacturing systems
(FMS), computer integrated manufacturing system (CIMS) and other flexible
processing equipment and the most important foundation for flexible manufacturing
systems. Commonly used with CNC lathes, CNC drilling machines, CNC boring,
CNC milling, CNC grinding machines, machining centers.
5 Tool
Metal cutting tools is an important tool for the completion of cutting, it directly
involved in the cutting process, workpiece removal from the excess metal layer. As a
flexible tool changes, and the effect was significantly, so it is cutting the impact of
productivity, quality and cost of processing the most active factor. Technical
performance of the machine itself continuously improve the situation, directly
determines the performance of machine tool's performance. According to
different uses and processing methods, tool cutter is divided into classes, drills,
broaches class, cutter type, thread cutting tools, gear cutting tools, abrasive type,
combination tool, automatic wire cutting tools, CNC machine tools and special
cutting tools, etc. . Metal cutting tool holder and cutting part containing. Holder is part
of the tool clamping, cutting part is directly involved in the cutting tool on the part of
the work.
6 Fixture
   Machining process, to determine the workpiece relative to the machine tool and the
correct position, and to this location is not in the process due to the impact of external
changes in technology and equipment, known as the machine tool fixtures, tool
fixtures that are used to make parts machine tool positioning and clamping
attachments. The machine tool to determine the correct relative to the workpiece
processing position to ensure that the surface to achieve the technical requirements
stipulated in the process is called localization. At fixed locations will be fixed reliably
clamp the workpiece to prevent workpiece for processing by the cutting force, inertial
force, centrifugal force, gravity, and the impact of shock and vibration, movement and
destruction took place position location process is called clamping . Workpiece in the
clamping fixture, including positioning and clamping the two areas. The applicable
scope and characteristics of the workpiece is divided into universal fixture, fixture,
and adjustable modular fixture fixture; in accordance with applicable lathe machine
into jigs, milling fixtures, drilling jigs, fixtures and CNC jig boring; by the power
source is divided into manual, pneumatic, hydraulic, gas hydraulic, electromagnetic,
etc. from the tight fixture.
Turning 7
   Turning is the machining method of one of the most widely used method is the
processing of shafts, set of parts of the main methods. Turning method can apply a
variety of rotary machining the outer surface of the body, such as internal and external
cylindrical surface, conical surface, forming rotary surface. The use of special
equipment or technology, in a lathe turning non-round parts can be surface, such as
cam, end thread, etc.. With the standard or special fixtures, you can also complete the
non-rotary rotary part on the surface of the processing. In the general machinery
manufacturing enterprises, accounting for lathe machine 20% ~ 35%, so turning in
machining method plays an important role. Turning in the lathe, turning, lathes, jigs
and turning parts constitute the complete process system. In general, turning the
workpiece is driven to do spindle turning movement is the main campaign to linear
motion of the tool feed movement. According to the precision machine tools used in
different turning precision machining can be achieved is not the same level.
8 Milling
Milling forming principle is applied tangent method, using multi-blade rotary cutting
tools in milling of plane, stepped surface, groove, forming surface of the cavity
surface, the surface processing of a spiral cutting method. It is the most widely used
processing methods. Milling, the cutter's rotation is the main motion, cutter
or workpiece coordinates along the direction of linear motion or rotary movement into
a movement. Coordinate with the direction of movement of different linkage and
matching of different shapes tool, you can achieve different types of surface
processing. Milling workpiece can be rough and semi- finishing.
9 reaming process
Reaming is a small diameter hole on the semi-refined and finishing methods. When
reamers reaming the hole wall removed from the workpiece trace metal layer, so that
the processed hole accuracy and surface quality is improved. In the hinge hole before
being processed through the drill hole or after the general need to drilling, reaming
process. According to the structure of different reamer, reaming can be processed
cylindrical bore, tapered bore. That can be hand operated can also lathes, drilling
machines, boring machines, CNC machine tools and other machine on. Reaming the
higher the machining quality, productivity than other methods of finishing high, but
its poor adaptability, a reamer can only be used for processing of one size of hole, step
holes and blind holes. In addition, the reaming of the hole has also been limited,
generally should be less than 80mm.
10, Boring
Boring a hole with a boring tool has been further processed on the finishing method.
