Abstract
A kind of camera bracket progressive die cold punching drawing process of the present invention calculates the tie point position of product and material strip using the plastic deformation tensile strength of material first according to the size surface area and shape of product；4 outer ring tie points are stamped out on the material strip of tie point for calculating product and material strip, and the inside between each adjacent 2 outer ring tie points stamps out 4 inner ring tie points；Reversal interlocking relay is provided to 4 outer ring tie point internal and external parts and carries out descending stretching step by step, makes full use of the plastic deformation of material, depth needed for being stretched to product and outer dimension；The product stretched and material strip are erect into placement in the width direction, separated from side by the product stretched and material strip waste material, realizes blanking；Finally the camera bracket finished product after blanking is completely examined.Avoid direct stamping products, product surface without flash and the indeformable purpose of blanking with what is reached.
Description
Technical field
The present invention relates to mobile phone components to machine field, and in particular to a kind of camera bracket progressive die cold punching stretching work
Skill.
Background technique
Camera bracket product is 5 face closures, on one side penetrating rectangular small metalwork, the usual thinkable processing work of people
Skill is exactly to cast.But it was verified that being extremely difficult to its product requirement.For the product of so small this kind of structure, how with
It is a kind of cheap, and the mode that can produce in enormous quantities goes production? be exactly continuous punching, and most punching press enterprise see it is this
Product does not all know how to set about.Because the processing difficulties of small metalwork thus are as follows: 1, camera to the size of bracket require compared with
Height, surface cannot have flash；2, the structure is stretched as rectangular stretching, and difficulty is high；3, require product blanking that cannot deform.
Therefore, above-mentioned processing difficulties how are solved, qualified camera bracket product is produced, is the related technical staff of industry
Technical problem urgently to be resolved.
Summary of the invention
In order to solve the above technical problems, we have proposed a kind of camera bracket progressive die cold punching drawing process, to reach
Avoid direct stamping products, product surface without flash and the indeformable purpose of blanking.
In order to achieve the above objectives, technical scheme is as follows:
A kind of camera bracket progressive die cold punching drawing process, comprising the following steps:
The first step, the tie point for calculating product and material strip: according to the size surface area and shape of product, material is utilized
Plastic deformation tensile strength calculates the tie point position of product and material strip；
Second step, punching: 4 outer ring connections are stamped out on the material strip of tie point for calculating product and material strip
Point, and the inside between each adjacent 2 outer ring tie points stamps out 4 inner ring tie points；
Third step, step drawing: reversal interlocking relay is provided to 4 outer ring tie point internal and external parts and carries out a descending step
Step stretches, and makes full use of the plastic deformation of material, depth needed for being stretched to product and outer dimension；
4th step, blanking: erectting placement for the product stretched and material strip in the width direction, the production that will be stretched from side
Product are separated with material strip waste material, realize blanking；
5th step is examined: finally being completely examined to the camera bracket finished product after blanking.
Preferably, in third step, after the stretch, outer ring tie point and inner ring tie point are gradually swollen for product and material strip
Greatly.
Preferably, in four steps, the jig that is formed using spring and sliding block is from side by the product stretched and material
Band waste material separates, and realizes blanking.
Through the above technical solutions, the present invention is accurately counted by using elder generation according to the shape, size and material of product
Its tie point with strip is calculated, punching press is carried out on material strip rather than the direct punching press on product, then by gradually stretching
Product is finally separated from material strip again, avoids the defect of direct stamping products by depth needed for product and outer dimension,
And the product surface stretched, without flash, blanking is indeformable after stretching, to reach novel in design, process layout is reasonable and answers
With the good purpose of effect.
Detailed description of the invention

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Below with reference to embodiment and specific embodiment, the present invention is described in further detail.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of camera bracket progressive die cold punching drawing process, comprising the following steps:
A1, the tie point for calculating product and material strip: according to the size surface area and shape of product, the plasticity of material is utilized
Deformation tensile strength calculates the tie point position of product and material strip；
A2, punching: stamping out 4 outer ring tie points 2 on the material strip 1 for calculating the tie point of product and material strip,
And the inside between each adjacent 2 outer ring tie points 2 stamps out 4 inner ring tie points 3；
A3, step drawing: to 42 internal and external parts of outer ring tie point provide reversal interlocking relays carry out it is descending step by step
It stretches, makes full use of the plastic deformation of material, depth needed for being stretched to product and outer dimension；Product and material strip are stretching
Afterwards, outer ring tie point and inner ring tie point gradually swell, and whole is in plum-shaped structure.
A4, blanking: erectting placement for the product stretched and material strip in the width direction, is controlled using what spring and sliding block formed
Tool is separated from side by the product stretched and material strip waste material, realizes blanking to get camera bracket finished product 4.
A5, finally camera bracket finished product 4 is completely examined.
In this example, the present invention is carried out by using elder generation according to the shape, size and material of camera bracket product accurate
Its tie point with strip is calculated, punching press is carried out on material strip rather than the direct punching press on camera bracket product, then
By depth and outer dimension needed for being gradually stretched to camera bracket product, finally again by camera bracket product from material strip
It is upper to separate, the defect of direct stamping products is avoided, and the product surface stretched, without flash, blanking is indeformable after stretching, thus
Achieve the purpose that novel in design, process layout rationally and good application effect.
Above-described is only a kind of camera bracket progressive die cold punching drawing process preferred embodiment of the invention, is answered
When pointing out, for those of ordinary skill in the art, without departing from the concept of the premise of the invention, can also make
Several modifications and improvements, these are all within the scope of protection of the present invention.
