Through adding the discharging block on the lower die, the stamping process with the opposite forming direction is combined with one set of die to complete the one-time stamping process, so that the development cost of the die is saved, the number of working procedures is reduced, the production steps and personnel are reduced, and the cost of the whole process of development, manufacture and production is saved.
Description
Technical Field
The utility model relates to a stamping die design, development technical field especially relate to a stamping die reverse hole flanging, beat protruding structure of unloading.
Background
In the manufacturing industry at present, the popularization of the stamping process is more and more large, for example, in electronic products, the stamping part accounts for about 80% -85%; in automobile and agricultural machinery products, stamping parts account for about 75% -80%; in light industrial products, the stamping parts account for more than 90%. The stamping part is designed to meet various functional types, the shapes of the stamping part are various, and due to the limitation of a die structure used in stamping production, only one side of a stamping die can be elastically compressed to realize the unloading function, so that the shapes with inconsistent forming directions can not be produced in the same set of dies.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned problem, provide a stamping die reverse hole flanging, beat protruding structure of unloading.
In order to solve the technical problem, the technical scheme of the utility model is that: the stamping die reverse hole flanging and convex discharging structure comprises a lower die holder, a spring is installed in the lower die holder through a screw plug, a lower backing plate and a concave die plate are sequentially installed above the lower die holder, a limiting fixing block is installed in the concave die plate and is installed on the lower backing plate through a fixing bolt, a stepped structure with a narrow top and a wide bottom is arranged in the limiting fixing block, the discharging block is installed in the limiting fixing block through a transmission thimble, the transmission thimble penetrates through the bottom of the lower backing plate to abut against the bottom of the discharging block, the bottom of the transmission thimble is arranged on the spring, the bottom of a convex die is fixed in the lower backing plate, and the top of the convex die penetrates into the discharging block.
Further, the spring is sleeved on the screw plug.
Furthermore, the fixing bolt penetrates from the top of the limiting fixing block to be in threaded connection with the lower backing plate.
The utility model discloses an increase the unloading piece at the lower mould, with shaping opposite direction's stamping process, combine one set of mould stamping process to accomplish, practiced thrift the development cost of mould, compressed process quantity, reduced production step and personnel, practiced thrift the cost of development, manufacturing and production overall process.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Wherein: 1. the device comprises a discharging block, 2, a limiting fixing block, 3, a fixing bolt, 4, a male die, 5, a transmission thimble, 6, a spring, 7, a plug screw, 8, a concave die plate, 9, a lower backing plate, 10 and a lower die base.
Detailed Description
The following describes the present invention with reference to fig. 1.
The reverse hole flanging and convex forming discharging structure of the stamping die comprises a lower die base 10, a spring 6 is arranged in the lower die base 10 through a screw plug 7, the spring 6 is sleeved on the screw plug 7, a lower backing plate 9 is sequentially arranged above the lower die base 10, the discharging device comprises a concave template 8, a limiting fixed block 2 is installed in the concave template 8, the limiting fixed block 2 is installed on a lower backing plate 9 through a fixed bolt 3, the fixed bolt 3 penetrates through the top of the limiting fixed block 2 to be in threaded connection with the lower backing plate 9, a stepped structure with a narrow top and a wide bottom is formed in the limiting fixed block 2, a discharging block 1 is of the stepped structure with the narrow top and the wide bottom, the discharging block 1 is installed in the limiting fixed block 2 through a transmission thimble 5, the transmission thimble 5 penetrates through the bottom of the lower backing plate 9 to abut against the bottom of the discharging block 1, the bottom of the transmission thimble 5 is arranged on a spring 6, the bottom of a male die 4 is fixed in the lower backing plate 9, and the top of the male die 4 penetrates through the discharging block 1.
The discharging block 1 is limited by the limiting fixing block 2 and the concave template 8 in horizontal displacement, and is limited by the limiting fixing block 2 and the lower backing plate 9 in vertical displacement, so that the discharging block 1 is guaranteed to have an effective displacement space to realize a discharging function. The driving thimble 5 penetrates through the lower backing plate 9 to transmit the elastic force of the spring 6 to the discharging block 1 so as to provide the discharging force for the discharging block 1. In the stamping process, the unloading block 1 firstly receives pressure to move downwards in the die assembly process, the pressure is transmitted to the spring 6 through the transmission thimble 5 to compress the spring 6, the elasticity is accumulated, and meanwhile, the male die 4 moves upwards relative to the unloading block 1 and acts on the sheet material to realize stamping operations such as hole flanging, convex beating and the like with the upper die; in the die opening process, the spring 6 releases elasticity and transmits the elasticity to the discharging block 1 through the transmission thimble 5 to finish the discharging work of the plate material on the male die 4.
The above description is only the specific implementation manner of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution of the present invention and the design of the present invention within the technical scope of the present invention.
