Description

A kind of Sheet Metal Forming Technology of integral door frame of heavy truck
Technical field
The present invention relates to a kind of Sheet Metal Forming Technology of integral door frame of heavy truck, belong to the Stamping Technology of Vehicle Body field.
Background technology
Field at heavy-duty car, the door frame of general heavy truck is the split Welding Structure, adopt the mode of split welding to weld, for novel overall structure door frame and inapplicable, because of the door frame quality state of this structure better, but complex-shaped, its Sheet Metal Forming Technology requires high, complicated.At present, do not have in the prior art a kind of at integrally-built door frame, efficiently, stay-in-grade process, can not satisfy the technology and the quality requirement of its product.
Summary of the invention
At above-mentioned prior art, the invention provides a kind of Sheet Metal Forming Technology of integral door frame of heavy truck, it is specially at the technology of integrally-built door frame, has advantages such as efficient, steady quality.
The present invention is achieved by the following technical solutions:
A kind of Sheet Metal Forming Technology of integral door frame of heavy truck, step is as follows:
(1) blanking (Q11-6.3 * 2500);
(2) cut out primary drying hole (E4S-800);
(3) draw (PWH-800-500);
(4) trimming and piercing die (JA39-800C);
(5) deburring, punching, flange, integer (JA39-800C);
(6) flange integer, side blow, side integer, deburring (JA39-800C);
(7) punching side integer (JA39-800C).
In the described step (1), adopt plate shearing machine that former sheet material is cut into the piece material.
In the described step (2), cut out the primary drying hole with the adjacent side location.
In the described step (3), with periphery location drawing and moulding.
In the described step (4), with interior shape location deburring, punching, flange and integer.
In the described step (5), with interior shape location deburring and punching.
In the described step (6), with interior shape location punching, side blow, side integer and deburring.
In the described step (7), with interior shape location trimming and piercing die.
More than said adjacent side location, periphery location, interior shape location be the basic terms in stamping technology field, belong to common practise, the adjacent side location is meant takes the positioner of pattern tool with two of the piece material adjacent limits (as: two the adjacent limits in the left side and front), so that the piece material is placed on the fixed position of mould.Periphery fixed be meant all will positioner contact location, all limits.Interior shape location is generally to be to be used for the operation that punching course may deform, refer to as required, the position of the placement operation part of mould is processed into the consistent profile of shape that is become with last preface, with the operation part of last preface and the adhered shape of mould, so that the operation part is fixed on the mould, in punching course, can not deform.
The invention has the beneficial effects as follows: the present invention can satisfy the production in enormous quantities of product, and cost is low, production efficiency is high, steady quality.
