Description
Technical field
The utility model is related to a kind of sheet metal component cold punching die of uneven thickness, belongs to the shaping in mechanical engineering and mould
Tool technical field.
Background technology
The processing of the sheet metal component differed in punching press industry, many section thicknesses, more using traditional cold stamping after, then subsequently
Machining carrys out volume production, and traditional processing mode is not only time-consuming and feed consumption, therefore, the utilization rate of material is not high, and machining surface
Quality is also bad.
Utility model content
In order to overcome the shortcoming of prior art, using a set of cold stamping/Cold forging original mach part rushing
The means of pressure/cold forging are substituted or reduced completely, and the overall quality and stock utilization produced speed, improve product is improved whereby, are reached
Reduces cost, increases productivity, and improves competitiveness, and the utility model provides the sheet metal component cold punching die of uneven thickness.
Technical solutions of the utility model are as follows：
The sheet metal component cold punching die of uneven thickness, including drift and cavity plate, the cavity plate are provided with counter-pressure block, described
Counter-pressure block can be moved up and down along cavity plate, die cavity and sheet metal component projection size, shape that the counter-pressure block is formed with cavity plate
Shape is adapted.
As preferred, there is screwed hole above the counter-pressure block, by external screw thread fixed stripper bolt and upper mould
Plate is connected, and the head of the stripper bolt is provided with pre-compressed spring, the stroke of the counter-pressure block and the form depth phase of workpiece
Unanimously.
Used as preferred, the material of the sheet metal component of the stamping mold processing can not be too hard, typically by mild steel, aluminium or copper material
Material and the preferable material of some plasticity ratios are made.
The utility model beneficial effect is：Material is realized by the extrusion forming process process step design of cold stamping or cold forging
The Rational flow of material and distribution, in the case of controllable according to progressively shaped by the concave-convex mold shape of optimization design, it is cold
Follow-up machining is saved or reduced to punching press/cold-heading directly in place, higher through the more preferable precision of the surface smoothness of cold forging, because removing/
Machine operations are reduced, so as to improve productivity and stock utilization.
Wherein, there is screwed hole above counter-pressure block, it is hung on upper die plate with external screw thread fixed stripper bolt,
The head of stripper bolt has pre-compressed spring to head on, and spring will be pressurized when counter-pressure block stress is up lifted, stroke and shaping
Depth is consistent, i.e., get into below how many apart from counter-pressure block just how many distance.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1, refering to Fig. 1 to Fig. 7.
The sheet metal component cold punching die of uneven thickness, including drift 1 and cavity plate 2, the cavity plate 2 are provided with counter-pressure block 3,
The counter-pressure block 3 can be moved up and down along cavity plate 2, and the die cavity 4 that the counter-pressure block 3 is formed with cavity plate is raised with sheet metal component
51 sizes, shape are adapted.
There is screwed hole above the counter-pressure block 3, be connected with upper die plate by external screw thread fixed stripper bolt, institute
The head for stating stripper bolt is provided with pre-compressed spring, and the stroke of the counter-pressure block 3 is consistent with the form depth of workpiece 5.
The sheet metal component of the stamping mold processing is made up of mild steel, aluminium or copper product.
The utility model principle is：Such as Fig. 4 and Fig. 5, the finished figure of the utility model converted products, in sheet metal component body 52
Top have a square metal plate projection 51.Traditional processing technology is, by raw material after cold punching is cut out, then by machine
Shape.
The utility model first obtains the optimal shape of raw material, such as Fig. 1, and calculate by CAE policy simulation softwards
The preferable cold forging amount of each work step, Metal plate is progressively thinning.During cold forging, punch press promotes raw material 5 to drift 1
Plastic deformation, material is clamp-oned toward the die cavity 4 of cavity plate 2, and remaining is extruded outward, now, obtains the product after first time cold forging
Shape, such as Fig. 2, work on, and counter-pressure block 3 remains downward pressure-plate-force, to provide three-dimensional stress needed for converted products,
The shape of second product after cold section is obtained, such as Fig. 3, this shape is also the use material realized after CAE policies are simulated
At least, stress is minimum, and required cold forging power is minimum, and at least design of deburring amount.By simple machine cuts, finally give
Finished product figure, such as Fig. 4 and Fig. 5.
Above-mentioned drawings and Examples are merely to illustrate the utility model, and any art those of ordinary skill is to it
The appropriate change or modification done, or use other flower pattern instead and make this technical change, all should be regarded as not departing from this practicality new
Type patent category.
