Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Example 1

As shown in fig. 1-3, the stretching die for the filter shell provided by the utility model comprises a lower die holder, wherein the lower die holder comprises a base plate 1, and the lower side of the base plate 1 is fixedly connected with a mounting rod 11. The stretching die of the embodiment can be installed on a stretching machine through the installation rod 11, a central hole is formed in the base plate 1, the locating ring 2 is detachably connected in the central hole, a counter bore 21 is formed in the inner annular surface of the locating ring, a first threaded hole is formed in the wall of the central hole, the locating ring 2 can be detached through a first screw 22, and the first screw 22 penetrates through the counter bore 21 and is in threaded connection in the first threaded hole.

The shaping bucket 3 is detachably connected to base plate 1 downside, shaping bucket 3 includes staving 31, staving 31's bung hole department integral type connects staving 32, staving 32 is detachably connected with base plate 1, be equipped with the hole of stepping down on the staving 32, base plate 1 downside is equipped with the second screw hole, make staving 32 and base plate 1 detachable through the second screw, second screw 36 pass the hole of stepping down and at second screw hole threaded connection, staving 31 bottom is equipped with the slide hole, slide bar 33 is connected in the slide hole in the slide, slide bar 33 upper end fixed connection backing plate 34, slide bar 33 outside cover has spring 35, spring 35 is fixed between staving 31 inboard bottom and backing plate 34.

The upper side of the base plate 1 is fixedly connected with the vertical rod 4, the vertical rod 4 is in sliding connection with the top plate 5, the top plate 5 is detachably connected with the stamping head 6, the upper side of the stamping head 6 is fixedly connected with the stud 61, the top plate 5 is provided with an avoidance hole, and the stud 61 passes through the avoidance hole and is in threaded connection with the nut 62. The punch 6 is coaxially disposed with the tub 31.

In the use, place the iron sheet in holding ring 2, fix a position the iron sheet through holding ring 2 for iron sheet and staving 31 coaxial setting, place the iron sheet put askew and lead to the shell after tensile to have the defect, after the iron sheet was placed, stretcher control roof 5 descends, and the punching press head 6 presses the iron sheet to remove in to staving 31, thereby makes the shell shaping. When the stamping head 6 is inserted into the barrel body 31, the base plate 34 can be lowered, so that the spring is in a pressed state, after the shell is formed, the stamping head 6 rises and leaves the barrel body 31, in the rising process of the stamping head 6, the base plate 34 rises under the action of the elastic force of the spring, so that the formed shell is ejected, and the automatic discharging function is realized. When the production needs to be replaced, the locating ring 2 is detached, the locating ring 2 with the proper size is replaced, the stamping head 6 is detached, the stamping head 6 with the proper size is replaced, the forming barrel 3 is detached, the forming barrel 3 with the proper size is replaced, and therefore compared with the mode of replacing a die in the prior art, the die change piece is not required to be replaced, and the replacement efficiency is remarkably improved compared with the prior art.
