Production method of foldable cassettes and die for one-step moulding

Abstract

The invention discloses a production method of foldable cassettes and a die for one-step moulding. The method comprises the steps of adopting a punch press and a die and automatically feeding tape, i.e. workpiece material, to the die by using a manually-operated feeder or a pneumatic feeder according to preset steps. The invention is characterized in that the adopted die is the die for one-step moudling. The production based on the die for one-step moulding comprises the following work steps: the first work step: cutting tape tails, punching three holds, and punching characters or signs; the second work step: cutting edges of the tape tails; the third work step: cutting tape heads and bending the tape tails primarily; the fourth work step: cutting edges of the tape heads and bending the tape tails secondly; the fifth work step: bending the tape tails and the tape heads; and the sixth work step: overlapping the tape tails and separating. The production method of the foldable cassettes, obtained by the invention, has the advantages as follows: one 25-on punch press is needed, the motor power is 2.2 Kw, a finished product can be obtained after one working procedure during operation process, and one person is enough for the operation; only one circulation link is needed, one set of transfer device is occupied, and the auxiliary working hours of incoming and outgoing workpieces are just one sixth of that of the prior art during punching.

Description

technical field [0001] The invention relates to a cassette production technology for fixing automobile exhaust pipes, in particular to a production method of a folding cassette and a one-time forming mold. Background technique [0002] The existing production method of folding cassettes is to go through blanking before rolling and forming, including cutting the head and tail, punching, punching, bending the tail and the head, bending the tail and stacking the tail, etc. Program, this production method, in order to form a production flow operation, there must be six 5-ton punches, and each punch needs to have a corresponding mold to cooperate with the required stamping tasks. 6.6 kilowatts, with 1 person in each process, 6 people are needed; 5 circulation links are required, and 5 sets of turnover equipment are required. In short, the existing process method is backward, occupying a large production area and transit warehouse area; there are many production auxiliary personn...
