Embodiment Construction
[0018] The present invention will be described in further detail below by way of implementation and accompanying drawings:
[0019] see figure 1 , the structure of the heat sink of the hydraulic torque converter is circular, and a plurality of arc-shaped long holes are distributed in a circular array on the top, and one side of each long hole has a flanging.
[0020] see figure 2 , image 3 , the mold includes a punch and a die; such as Figure 4 As shown, the punch includes a punch upper die base 3, a punch edge block 4, a plastic rubber pad 5, a punch pressing block 6, a positioning pin 7, a bolt 2, and a hanging nail 1, which are connected sequentially from top to bottom. composition; such as Figure 5 As shown, the die includes a die base 9, a die spring pad 10, a spring 12, a die edge pad 13, a die pressing block 15, a die edge block 14, Bolt 8 and pin 11 form.
[0021] Such as Figure 4 In the shown punch, the punch edge block 4 is placed in the center of the pun...

A piercing and flanging forming mould for radiating fins of hydraulic torque converters comprises a male mould and a female mould. The male mould comprises an upper male mould holder (3), a male mould cutting edge block (4), a plastic rubber pad (5), a male mould press block (6), positioning pins (7), bolts (2) and suspension nails (1) from top to bottom sequentially. The female mould comprises a lower female mould holder (9), a lower female mould spring pad (10), springs (12), a female mould cutting edge pad (13), a female mould press block (15), a female mould cutting edge block (14), bolts (8) and pins (11). By using the piercing and flanging forming mould, the operation of piercing one by one frequently is avoided, processing procedure is simplified, labor intensity and production cost are reduced, one-step positioning and one-step piercing and flanging forming can be realized, quality of the radiating fins of the hydraulic torque converters is stabilized and production efficiency is increased. In addition, the piercing and flanging forming mould is longer in service life, simple in structure and safe and reliable.
Description
technical field [0001] The invention relates to a mold, in particular to a punching and flanging forming mold for a cooling fin of a hydraulic torque converter. Background technique [0002] The structure of the heat sink of the hydraulic torque converter is a ring-shaped thin sheet, on which a plurality of long holes are distributed in a circular array, and one side of the long holes has a flange flange. At present, the processing technology of the heat sink of the torque converter is mainly to punch out the ring sheet first, drill the process hole on the drilling machine, and then position it with the process hole, and punch the holes one by one on the punching machine. How many flanges are there? How many times do you have to rush. Therefore, adopting the above-mentioned technology to carry out the punching and flanging of the heat sink of the hydraulic torque converter has the following defects: one, many processes, high labor intensity, and low efficiency; two, the mol...
