Abstract
The invention discloses a machining process of bent cross beams of heavy truck frames, comprising the steps of (1) blanking; (2) blank punching; (3) bend forming; (4) side sizing and (5) multihole punching. The method has the advantages of improving the quality of the bent cross beams, reducing the scrap rate in the production process and labor intensity, improving the production efficiency and the like.
Description
Technical field
The present invention relates to a kind of processing technology of bent cross beams of heavy truck frames, belong to the former plate punching press of automobile field.
Background technology
In the field of heavy-duty car, the sheet material of bent cross beams is thicker, is generally more than the 6mm, is U-shaped bool, and the side of bent cross beams is a curved surface.Existing processing Sheet Metal Forming Technology is blanking, and---blanking and punching---bent into shape---side blow adopts the certain quality problem of the bent cross beams existence of this process processing, thereby causes the assembly problem of bent cross beams.The quality problems of the process of bent cross beams: behind the bent into shape, the side rebound phenomenon is serious and ripple glaze is arranged, and influences the processing of subsequent processing side blow simultaneously: the not disconnected phenomenon of drift is serious during side blow, and the position, hole of side is difficult to assurance, percent defective height.Need hole milling to satisfy assembling carrying out crossbeam when assembling riveted joint, but the crossbeam assembly that assembles still can't guarantee the assembling of frame assembly, must carry out shaping earlier, so when frame assembly assembles, also need to carry out hole milling.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of processing technology of bent cross beams of heavy truck frames in order to address the above problem, and it has the product quality that improves bent cross beams, reduce percent defective in the production process and labour intensity, advantage such as enhance productivity.
For achieving the above object, the present invention adopts following technical scheme:
A kind of processing technology of bent cross beams of heavy truck frames, its step is:
(1) blanking (Q11-6 * 2500);
(2) blanking and punching (J31-1250);
(3) brake forming (THP27-1000);
(4) school, side shape (THP27-1000);
(5) towards porous (J31-1250).
In the described step (1), adopt plate shearing machine that former sheet material is cut into the piece material consistent with the material machine direction.
In the described step (2), locate profile and towards the hole and two fabrication holes of bottom surface with two adjacent gulde edges.
In the described step (3), with the location brake forming of two fabrication holes described in the step (2).
In the described step (4), with school, side, the location of two fabrication holes described in the step (2) shape.
In the described step (5), with the hole of the location of two fabrication holes described in the step (2) towards two sides.
The invention has the beneficial effects as follows: be fit to the camber beam of machining thick plates material, not only reduce the percent defective in the production process, also improved operating efficiency simultaneously, reduced production cost, product quality is guaranteed.

The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing and embodiment.
Method of the present invention is:
(1) blanking: adopt plate shearing machine former sheet material is cut into material machine direction unanimity piece material (direction shown in the arrow among the figure) as Fig. 1 piece material;
(2) blanking and punching: blanking and piercing die is installed on the forcing press, locatees profile and towards the hole and two fabrication holes of bottom surface, as shown in Figure 2 with adjacent side.The blanking and piercing die of this operation is after the shape of product reaches product requirement, to try out the profile of plate accurately and be this mould that the solid line of Fig. 2 is partly reprocessed after the shape of school, side.
(3) brake forming: on bending and forming die setting pressure machine, product behind the blanking and punching is located with two fabrication holes, be placed on the mould, by pressing direction shown in Figure 3, brake forming, molded article requires a angle 90 °～92.5 ° scopes shown in Fig. 3 a, Fig. 3 b, Fig. 3 c, and requires to guarantee that the bottom surface of product is smooth.
(4) school, side shape: school, side shape mould is installed on the forcing press, with two fabrication holes location product shown in Figure 3 is placed on the mould, carry out school, side shape by pressing direction shown in Figure 4, must be shown in Fig. 4 a, Fig. 4 b, Fig. 4 c product, wherein the b angle equals 90 °, opening grade tolerance of size c is ± 1, eliminates the wave of side.
(5) side blow: will be installed on the forcing press towards multiple-hole die, with two fabrication holes location, by pressing direction shown in Figure 5 hole towards two sides, must be shown in Fig. 5 a, Fig. 5 b, Fig. 5 c product.
Claims (1)
1. the processing technology of a bent cross beams of heavy truck frames is characterized in that, its step is:
(1) blanking; Adopt plate shearing machine that former sheet material is cut into the piece material consistent with machine direction during blanking;
(2) blanking and punching is installed in blanking and piercing die on the forcing press, locatees profile and towards the hole and two fabrication holes of bottom surface with adjacent side;
