Abstract
The invention discloses a punching technology of an automobile chassis component. By means of a simple method, a product of a complex structure is machined, locking rings of a die are reduced, and the quality of the product is improved. The punching technology comprises the following steps that firstly, prepared materials are added and injected; secondly, an upper plate is notched; thirdly, tongue cutting is carried out on a front plate and a rear plate; and fourthly, trimming is carried out. According to the actual situation, the prepared materials are added and injected. To facilitate the punching of the later procedure, a notch in the upper plate is removed through notching, and an arc section notch can be conveniently cut later for linkage. When the residual outline is punched and cut away, the arc section notch can be in good linkage with a circular arc opening finally obtained, and in the final punching, waste can disengage easily. The design of the composite die is combined, and the additional procedure cannot be increased.
Description
Technical field
The present invention relates to a kind of processing method of automotive chassis components, more particularly, to a kind of rushing for Automobile Chassis Parts
Cut out technique.
Background technology
Punching is the part or the process for stamping of blank that required form and size are isolated from plate.Punching is using punching
The cutting edge of mould makes plate produce detrusion along certain contour line and separate.The shared ratio in punching production of punching is most
Greatly.In blanking process, in addition to the metal near shearing contour line, plate itself does not produce plastic deformation, so by flat board
The part of punch press process remains a flat shape.
It is complete at the right-hand member of the parts during manufacturing Automobile Chassis Parts as shown in Figure 1 now
Into the breach of a circular arc, and the bore of the circular arc opening is larger, more intuitively be arc notch height compared with
Greatly.If being processed using simple punching mode, the corresponding blade lengths that it is used are also larger, during punching
It is easily caused mold notch to burst apart.Additionally due to difference of the parts as blanking part dimensional thickness everywhere, and size also has
Changed, the processing of punch die and assembly technology are also different according to physical condition.It is more complicated that existing product design becomes, and makes product
It is more difficult that the processing of product becomes.General technology cannot ensure the peace in the life-span of mould, the stability of product and operation
Quan Xing.
The content of the invention
The technical problem to be solved is to provide a kind of punching process of Automobile Chassis Parts, using more letter
Single method reduces the lock ring of mould realizing the processing of complex structure product, and the quality of product is also improved.
The present invention solve the technical scheme that adopted of above-mentioned technical problem for：A kind of punching work of Automobile Chassis Parts
Skill, comprises the following steps：
A. plus expect injection：Material injection Cheng Youqian plate bodys, upper plate body are connected three plate body structures for surrounding with rear plate body；
B. incised notch is carried out on upper plate body：A notch is cut out on upper plate body, described notch left side is perpendicular to upper
Flanging between plate body and front plate body；
C. carry out cutting tongue on front plate body and rear plate body：Left side along the notch is downward, in front plate body and back plate
Curved line on body along the circular arc opening wished to get laterally is cut to after predetermined length and is stopped, and obtains arc
Breach, is acute angle for cutting the angle between the blade one of front plate body and the right side of front plate body, for cutting the knife of rear plate body
Angle between piece two and the right side of rear plate body is acute angle；
D. deburring：The breach for cutting the arc obtained after tongue along front plate body carries out the punching unnecessary profile of excision, along rear
Plate body cuts the breach of the arc obtained after tongue and carries out the unnecessary profile of punching excision, reaches the circular arc opening shape of final product
Shape.
In described step a, on the upper plate body of three plate body structures of injection mo(u)lding location hole is provided with.Location hole sets
Put is, for positioning, to obtain standardized product structure when being molded.And in subsequent steps can cut off location hole.
The cross section of three described plate body structures is inverted U-shaped.
In described step b, notch is rectangular configuration, the front side edge of the notch and back side edge parallel to upper plate body with it is front
Flanging between plate body.The notch of rectangular configuration is easy to cutting, it is also possible to the arc that tongue is obtained of cutting in next process
Breach well in linking.
Described location hole is located in notch, is cut off location hole while notch is cut out in stepb.
It it is 50 degree for cutting the angle between the blade one of front plate body and the right side of front plate body, for cutting in step c
It is 50 degree to cut the angle between the blade two of rear plate body and the right side of rear plate body.Carried out cutting lacking for arc with this angle
Mouthful so that the breach can cut off unnecessary profile and be connected well with the deburring in next step.By the punching of standard just
Can cut off and obtain whole circular arc opening.
Described blade one, blade two is adopted and tiltedly carves structure.Tiltedly carve the blade one of structure, blade two to be not easy to burst apart,
Improve its service life.
Compared with prior art, it is molded it is an advantage of the current invention that to be preceded by expectation according to practical situation.In order to
Facilitate subsequent handling to be punched, first a notch is removed in upper plate body using incised notch, convenient follow-up excision arc breach is held in the mouth
Connect.And the setting of the breach of arc is in order to when punching excision unnecessary profile is carried out, with the circular arc for finally obtaining
Shape opening is connected well, and after last punching, what waste material can be clear-cut comes off.The present invention sets with reference to composite die
Meter, will not increase excessive extra operation.
