Abstract

The invention discloses a moulding technology for automobile aluminum products, which includes moulding, edge cutting, punching, flanging, edge wrapping and inscription, the moulding, the edge cutting and the flanging are a first process which includes specific steps of arranging a plate on a lower die, moulding the plate by using an upper die and the lower die, cutting periphery waste material of the plate by using an edge cutting blade (1) before the upper die moves to the bottom, next using an flanging blade (2) to flange and finishing the moulding, the edge cutting and the flanging processes when the upper die moves to bottom; the edge wrapping, the punching and the inscription are a second process which includes specific steps of overturning the plate for 360 DEG and arranging the plate on the lower die, and simultaneously finishing the edge wrapping, the punching and the inscription processes when the upper die moves to the bottom. The technical solution provided by the present invention can save two dies and a press, is convenient for maintenance, and reduces tolerance accumulation during the four processes for the original moulding technology, so that stability of products is better.

Description

The moulding process that is used for automobile aluminum products spare

Technical field

The present invention relates to a kind of moulding process of metalwork, especially relate to a kind of moulding process that is used for automobile aluminum products spare.

Background technology

For the making of automobile metal spare processing, particularly alumiaum article thermal insulation board for example, present moulding process mainly adopts four procedures: be respectively the first procedure moulding, mold the plate moulding; The second operation work edge-cutting and hole-punching, cut unnecessary plate and go out the institute porose; The three process flange is translated into vertical edges to needs bound edge part earlier; The 4th procedure bound edge is carved characters.Adopt four pairs of moulds of this arts demand and press, the manufacturing cost in early stage of mould is big, the construction cycle is long, and the production efficiency of four procedure moulding is also dissatisfied; The most important product quality problem that still stamps out, because the tolerance of multiple working procedure accumulative total makes the stability of product not good, this has brought a series of problems also for client's follow-up punching press.In addition, owing to adopt four pairs of moulds and press, maintenance is also inconvenient.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of moulding process that is used for automobile aluminum products spare that can reduce die cost and can reduce inter process tolerance accumulative total.

Technical problem to be solved by this invention is achieved by the following technical solution: it comprises moulding, side cut, punching, flange, bound edge and carves characters, it is characterized in that: (1) with moulding, side cut and flange as first procedure, plate is placed counterdie, patrix is descending, mould is earlier with plate forming about utilizing, utilized the side cut edge of a knife to cut the peripheral waste material of plate on earth at the patrix stroke, and then utilize the flange edge of a knife to carry out flange, the patrix stroke can be finished moulding, side cut and overturning process on earth the time; (2) with bound edge, punching and carve characters as second operation work, the plate upset through the first procedure moulding, side cut and flange is placed counterdie for 360 °, patrix is descending, bound edge, the punching and carve characters and can finish simultaneously on earth time of patrix stroke.

The technique scheme that the present invention adopts only needs to adopt two procedures, can save two pairs of moulds and press, and be convenient to maintenance; Also reduced the tolerance accumulative total of originaling forming technology between four procedures, made the stability of product better.

The specific embodiment

The moulding process that the present invention is used for automobile aluminum products spare comprises moulding, side cut, punching, flange, bound edge and carves characters, with moulding, side cut and flange as first procedure, utilize first pair of mould and press, plate is placed counterdie, patrix is descending, mould is earlier with plate forming about utilizing, utilized the side cut edge of a knife 1 to cut the peripheral waste material of plate on earth at the patrix stroke, and then utilize the flange edge of a knife 2 to carry out flange, the patrix stroke can be finished moulding, side cut and overturning process on earth the time; The first procedure patrix flange edge of a knife and the side cut edge of a knife are made on same bloom, and counterdie flange cutting edge and trimming edge are also made on same bloom, are convenient to the die debugging and the maintenance in later stage like this.It is downward that first procedure utilizes the flange edge of a knife to need all the position of bound edge to translate into straight flange earlier.With bound edge, punching and carve characters as second operation work, utilize second pair of mould and press, the plate upset of crossing through the first procedure moulding, side cut and flange is placed counterdie for 360 °, patrix is descending, bound edge, the punching and carve characters and can finish simultaneously on earth time of patrix stroke can well guarantee the precision in hole like this.After 360 ° of the plate upsets, need the flange at bound edge position to become direction upwards, when patrix presses down, utilize the hypotenuse at patrix edge inwardly to push the formation bound edge.

Claims

1, a kind of moulding process that is used for automobile aluminum products spare comprises moulding, side cut, punching, flange, bound edge and carves characters, and it is characterized in that:

(1) with moulding, side cut and flange as first procedure, plate is placed counterdie, patrix is descending, mould is earlier with plate forming about utilizing, utilized the side cut edge of a knife to cut the peripheral waste material of plate on earth at the patrix stroke, and then utilize the flange edge of a knife to carry out flange, the patrix stroke can be finished moulding, side cut and overturning process on earth the time;

(2) with bound edge, punching and carve characters as second operation work, the plate upset through the first procedure moulding, side cut and flange is placed counterdie for 360 °, patrix is descending, bound edge, the punching and carve characters and can finish simultaneously on earth time of patrix stroke.
