Description

Technical Field

[0001] The invention belongs to the field of vehicle trial shaping, in particular to the field of a side shaping device for multiple vehicle models which is easy to adjust. Background Art

[0002] The side shaping process in the trial production stage of the side outer panel is very different from that in the mass production stage. In the mass production process, the vertical movement of the press slide is converted into horizontal or inclined movement through the wedge mechanism, and then the shaping die is driven to complete the side shaping. At present, in the field of automobile trial sample development, the side shaping of the side outer panel sheet metal parts is a major difficulty. There are negative stamping angles in the parts that match the top cover and tailgate, and their forming can only be completed through side shaping; the stamping process of the side panel in the traditional trial production stage is divided into 6 sequences (including laser trimming and hole cutting processes); among them, process 1. P10 drawing, drawing all A surfaces and most of the profiles of the parts; 2. Rough laser trimming and hole cutting; 3. OP20 flanging shaping, forming the parts that do not need side shaping and have not been formed into the product shape in the drawing process To product shape; 4. OP30 side shaping, side shaping the overlap between A and B pillars and the top cover; 5. OP40 side shaping, side shaping the overlap between B pillar and tail light and the top cover and tailgate; 6. Accurate trimming, hole cutting, and each process after drawing; From the above side outer panel stamping process, it can be seen that during the trial production, side shaping requires two processes and two pairs of side shaping dies to complete the production. The CAM manufacturing cycle required for the development of side shaping is long, with a normal production cycle of nearly 90 days, and a total of one set of drawing dies and two sets of side shaping dies are required, which makes the mold development cost very high.

DETAILED DESCRIPTION

[0020] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] like Figures 1 to 7 The side shaping device for side panel shaping of multiple vehicle models which is easy to adjust comprises a tooling platform 1, a side shaping mold core 11 is provided on one side of the tooling platform 1, a shaping piece is placed on the side shaping mold core 11, a pressing piece 12 is provided above the shaping piece to be pressed tightly, and an upper mold casting body is also fixed on the pressing piece 12; when in use, the pressing piece is driven downward by the upper mold casting body, and the pressing piece 12 is tightly pressed against the shaping piece; at the same time, a plurality of side shaping units are provided on the other side of the tooling platform 1 Element 2, the side shaping unit 2 includes a guide rail seat 21, a hydraulic cylinder 222, a knife block slide 23, and a side shaping knife block 24, and the knife block slide 23 is fixedly connected to the telescopic shaft of the hydraulic cylinder 22, and the side shaping knife block 24 is slidably connected to the knife block slide 23. When the hydraulic cylinder 22 is working, the telescopic shaft of the hydraulic cylinder will push the knife block slide to move in the direction close to the shaping piece, and at the same time, the side shaping knife block set on the knife block slide will be in close contact with the end of the shaping piece to complete the side shaping of the product;

[0022] In addition, a self-lubricating guide plate 25 is provided between the knife block slider 23 and the guide rail seat 21. The self-lubricating guide plate is a novel lubricating bearing having the characteristics of both metal bearings and self-lubricating bearings. The metal matrix bears the load, and the specially formulated solid lubricating material plays a lubricating role. It has high load-bearing capacity, impact resistance, high temperature resistance, strong self-lubricating ability, etc. It is particularly suitable for heavy loads, low speeds, reciprocating or swinging occasions that are difficult to lubricate and form oil films. It is not afraid of water flushing and other acid erosion and scouring, and improves the reliability of the structure between the knife block slider 23 and the guide rail seat 21.

[0023] In order to meet the needs of side shaping of multiple models, the side shaping unit 2 is set to two structures, namely the first side shaping unit 3 and the second side shaping unit 4, wherein the hydraulic cylinder 22 of the first side shaping unit 3 is arranged parallel to the guide rail seat 21, and the hydraulic cylinder 22 of the second side shaping unit 4 is arranged obliquely on the guide rail seat 21, and the two different side shaping unit structures can realize shaping of the side shaping at multiple angles;

[0024] Furthermore, conventional side-adjusting molds generally adopt a structure in which the side-adjusting unit is fixed on a tooling platform 21. Such a structure is difficult to adjust in detail, and since the side-adjusting unit is fixed, the left and right side-adjusting range is relatively limited; therefore, a plurality of groups of first mounting grooves 13 and second mounting grooves 14 are provided on the upper surface of the tooling platform 1, and a slide bar is provided under the guide rail seat 21, and the slide bar is embedded in the first mounting groove 13 or the second mounting groove 14. For ease of understanding, the transverse sections of the side-adjusting mold core 11 and the pressing piece 12 are both bent. Here, the straight end of the side-adjusting mold core 11 is set as a horizontal section 111, and the bent end is set as a bent section 112. Then, the first mounting groove 13 is set on one side of the horizontal section 111 of the side-adjusting mold core, and the second mounting groove 14 is set on one side of the bent section 112 of the side-adjusting mold core. Among them, the number of grooves of the first mounting groove 13 is 4, and the four The mounting grooves are distributed in a cross shape as a whole, and the number of the second mounting grooves 14 is 6, which are cross-shaped as a whole. Compared with the first mounting grooves, the mounting grooves in the horizontal direction are set in two rows; mounting holes 15 are provided around the first mounting groove 13 and the second mounting groove 14, and bolts 16 are fastened in the mounting holes 15, and the side assembly unit 2 is fixedly installed on the tooling platform 1 by the bolts 16; and the positions of the mounting holes 15 are set on the path of the sliding rod moving forward, backward, left and right, and the distances between adjacent mounting holes 15 are the same; it should be noted here that although the drawings in the specification show that the first side assembly unit is arranged at the first mounting groove and the second side assembly unit is arranged at the second mounting groove, in actual use, in order to meet the needs of multiple models and multiple angles, the second side assembly unit can also be placed on the first mounting groove, and the first side assembly unit can also be placed on the second mounting groove.

[0025] Compared with the usual technical scheme, the present technical scheme adopts a universal side shaping mechanism, which can realize various types of side panels of different car models and side shaping at multiple angles, thereby reducing the number of molds and having a strong versatility in function. For subsequent stamping trial production, the development cost of mold CAM manufacturing is greatly reduced and the mold development cycle is shortened. Although manual hand-held production is required during production and the production rhythm is slow, since it is a trial mold, the batch size is generally small (no more than a few hundred pieces at most), and the workload is within an acceptable range. Therefore, compared with traditional schemes, the use of this structure has obvious cost advantages in part stamping trial production.

[0026] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
