Abstract

The utility model discloses a punching processing die of an automobile damper spring upper seat. The punching processing die of the automobile damper spring upper seat can position the workpiece during the downward-pressing process firstly, then performs punching process, and has high machining precision and high rate of finished products. An upper die plate, an elastomer and a swaging plate are connected into an integrity through a tensioning rod, a punch is connected with the upper die plate fixedly, a swaging boss is arranged on the swaging plate, a head portion of the punch penetrates through the swaging plate, the head portion of the punch is above a bottom end surface of the swaging boss on the swaging plate when the workpiece is unprocessed. A workpiece positioning boss which is provided with a punching is arranged on a male die, relief holes are arranged on the male die and a lower die plate. The swaging plate is arranged on the processing die to enable the male die to press the workpiece on the mail tie before the contact between the workpiece and the punch, then the punch contacts the male die, and a punching process is performed. The punching processing die of the automobile damper spring upper seat has the advantages of being stabile in punching processing, being high in machining precision, being high in finished products rates, reducing producing cost, having a material-stripping function owning to the combination of the swaging plate and the elastomer, being simple in structure and being convenient to operate.

Description

Automobile absorber spring seat of honour punching processing mould
Technical field
The utility model relates to a kind of automobile absorber spring seat of honour punching processing mould.
Background technology
The general 308 automobile absorber spring seats of honour are welded on the automobile absorber outer shell, are used for keeping the support spring upper end.
In general 308 automobile absorber spring seat of honour process, need to process centre bore in the seat of honour after moulding.At present, the punch process mode is adopted in the processing of centre bore.In punching course, workpiece to be processed directly is placed on the punch, the central straight of drift alignment pieces taps into capable punching processing.Because from top workpiece is not positioned in the process, the punching processing precision is low, percent defective is high, affects the quality of product, has increased the production cost of enterprise.
The utility model content
The purpose of this utility model is for the technological deficiency that exists in the prior art, can in pressing down process workpiece be located first and provide a kind of, carries out punch process again, and machining accuracy is high, the automobile absorber spring seat of honour punching processing mould that yield rate is high.
For realizing that the technical scheme that the purpose of this utility model adopts is:
A kind of automobile absorber spring seat of honour punching processing mould, it is characterized in that, comprise upper die unit and lower die unit, described upper die unit comprises cope match-plate pattern, elastomer, holding pad, drift, link into an integrated entity by tie rod between described cope match-plate pattern, elastomer and the holding pad, described cope match-plate pattern is connected with the power set of punch press by die shank, be fixedly connected with drift on the described cope match-plate pattern, be provided with the binder boss on the described holding pad, described drift head passes described holding pad, during unprocessed workpiece, the drift head is higher than the lower surface of binder boss on the described holding pad; Described lower die unit comprises lower bolster, punch, described punch is fixedly connected with described lower bolster, be provided with the workpiece positioning boss on the described punch, the position corresponding with workpiece center hole is provided with punching on the described workpiece positioning boss, is provided with the material spilling hole that is communicated with described punching on described punch and the lower bolster.
Described cope match-plate pattern is slidingly connected by guide pin bushing and the guide pillar that matches with lower bolster.
Described elastomer is elastomeric material.
Compared with prior art, the beneficial effects of the utility model are:
1, has holding pad on the punching processing mould of the automobile absorber spring of the present utility model seat of honour, can drift with first workpiece is pushed down on punch before workpiece contacts, drift contacts with workpiece and carries out punching processing, make punching processing more stable, machining accuracy is high, yield rate is high, is conducive to reduce production costs.
2, the holding pad of automobile absorber spring of the present utility model seat of honour punching processing mould is by also having the material of taking off function with elastomeric combination, and is simple in structure, easy to operate.
Description of drawings
Figure 1 shows that the schematic diagram of the utility model automobile absorber spring seat of honour punching processing mould.
Among the figure: 1. guide pin bushing, 2. cope match-plate pattern, 3. tie rod, 4. die shank, 5. drift, 6. elastomer, 7. holding pad, 8. punch, 9. lower bolster, 10. guide pillar, 11. material spilling holes, 12. punchings.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The schematic diagram of the utility model automobile absorber spring seat of honour punching processing mould comprises upper die unit and lower die unit as shown in Figure 1.Described upper die unit comprises cope match-plate pattern 2, elastomer 6, holding pad 7, drift 5, and described elasticity 6 bodies can adopt elastomeric material.Link into an integrated entity by tie rod 3 between described cope match-plate pattern 2, elastomer 6 and the holding pad 7, described cope match-plate pattern 2 is connected with the power set of punch press by die shank 4.Be fixedly connected with drift 5 on the described cope match-plate pattern 2, be provided with the binder boss on the described holding pad 7, described holding pad 7 is passed in described drift 5 lower ends, and during unprocessed workpiece, drift 5 lower ends are higher than the lower surface of binder boss on the described holding pad 7.Described lower die unit comprises lower bolster 9, punch 8, described punch 8 is fixedly connected with described lower bolster 9, be provided with the workpiece positioning boss on the described punch 8, the position corresponding with workpiece center hole is provided with punching 12 on the described workpiece positioning boss, is provided with the material spilling hole 11 that is communicated with described punching on described punch 8 and the lower bolster 9.Described cope match-plate pattern is slidingly connected by guide pin bushing 1 and the guide pillar 10 that matches with lower bolster.
During use, workpiece to be processed is placed on the workpiece positioning boss of punch.Power set drive cope match-plate pattern, elastomer, holding pad, drift move down.Binder boss on the holding pad at first contacts with workpiece to be processed, and because the operation elastomer of pressure is crushed, so that the head of drift passes holding pad punch process workpiece to be processed, and cooperates with punching on the punch and to stamp out centre bore.The waste material that punching press produces falls from material spilling hole.After punching press was finished, power set drove holding pad, drift rises, because elastomeric elastic force operation, holding pad resets, and the workpiece after the processing is taken off from drift.Simultaneously, in the head retraction holding pad of drift, finish the processing of a workpiece.
The above only is preferred embodiment of the present utility model; should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
