Description
Technical field
The present invention relates to a kind of transmission cover punching die.
Background technology
Cold stamping is a kind of advanced method for metal working, and it has production efficiency high, and processing cost is low, material
Utilization rate is high, product size stable accuracy, and simple to operate to be easily achieved mechanization and automation etc. a series of excellent
Point, thus be widely used in batch production, occupy in modernization industry production particularly significant
Status, be essential processing method in national defense industry and civilian industry production.
Transmission cover is an indispensable part in washing machine, and production batch is larger, most fast in minimum time use
Speed produce most parts, while ensure quality again, this just needs designer to pay attention in design
The problem of a lot, the manufacturing cost of existing mould is high, and service life is short, product of poor quality, it is necessary to through
Row is processed again, can not preferably ensure final product quality and high qualification rate, while it is slow to change the mold speed, increase
Punching production preparation amount and time.
The content of the invention
The technical problem to be solved in the present invention is：Overcome deficiency in the prior art, there is provided one kind ensures finished product
Quality and high qualification rate, quick die change device, reduce punching production preparation amount and shorten time
Transmission cover punching die.
The technical solution adopted for the present invention to solve the technical problems is：A kind of transmission cover punching die, tool
There are die shoe and upper bolster, guider is provided between die shoe and upper bolster, the die shoe is provided with recessed
Mould, it is fixedly mounted between cavity plate and die shoe by straight pin and soket head cap screw, upper bolster is provided with die shank,
The bottom surface of the upper bolster is provided with punch-pin, and punch retainer, punch retainer and upper mould are arranged with punch-pin
Backing plate is provided between seat, the upper end of the punch-pin is arranged with stripper, passed through between upper bolster and stripper
Unloading bolt is connected, and the first spring, punch-pin are arranged with the unloading bolt between punch retainer and stripper
Second spring is provided between fixed plate and stripper.
Further, described die shank is using rigid die shank.
Further, described guide pin bushing and guide post surface carry out carburizing heat treatment, and carburizing depth is 0.7~
1.2mm, hardness are 58~62HRC, and material is 20 steel.
Further, described guider includes guide pin bushing and guide pillar, and guide pillar is provided with guide pin bushing.
Further, described die shank is provided with anti-rotation with upper bolster junction and sold, and can prevent the axle in shell
Hold outer shroud to rotate, without dismantling or changing grease nipple, alignment pin or other devices..
Further, the second cylinder pin connection is passed through between described upper bolster, backing plate and punch retainer.
The beneficial effects of the invention are as follows：Present invention guarantee final product quality and high qualification rate, quick die change device,
Reduce punching production preparation amount and shorten time, service life length, reduce manufacturing cost.

Embodiment
Presently in connection with accompanying drawing and preferred embodiment, the present invention is further illustrated.These accompanying drawings are simplification
Schematic diagram, only illustrate in a schematic way the present invention basic structure, therefore its only show it is relevant with the present invention
Composition.
A kind of transmission cover punching die as shown in Figure 1, has die shoe 1 and upper bolster 8, die shoe 1
Guider is provided between upper bolster 8, the die shoe 1 is provided with cavity plate 3, cavity plate 3 and die shoe 1
Between be fixedly mounted by straight pin 2 and soket head cap screw 17, upper bolster 1 is provided with die shank 12, described
The bottom surface of upper bolster 8 is provided with punch-pin 16, and punch retainer 9, punch retainer 9 are arranged with punch-pin 16
Backing plate 10 is provided between upper bolster 8, the upper end of the punch-pin 16 is arranged with stripper 4, upper bolster 8
It is connected between stripper 4 by unloading bolt 11, the discharging spiral shell between punch retainer 9 and stripper 4
The first spring 6 is arranged with nail 11, second spring 6-1 is provided between punch retainer 9 and stripper 4.
Die shank 12 carries out carburizing heat treatment using rigid die shank, guide pin bushing 7 and the surface of guide pillar 5, and carburizing is deep
It is 58~62HRC to spend for 0.7~1.2mm, hardness, and material is 20 steel.
Guider includes guide pin bushing 7 and guide pillar 5, and guide pillar 5, die shank 12 and upper bolster 8 are provided with guide pin bushing 7
