[0018] As Figure 1 shown, an automobile anti-collision beam profile shaping mechanism includes: A power device 1, the power device 1 is arranged on one side of a bracket 8, the power device 1 is connected with an upper pressing head assembly 2 for shaping a product, on the bracket 8, and at positions corresponding to both ends of the upper pressing head assembly 2, there are arranged lower pressing stroke limiting components 5, and at the bottom of the bracket 8, there are self-locking wheels for easy movement; A load-bearing and supporting component 3, the load-bearing and supporting component 3 is respectively arranged at the tops of both ends of the bracket 8 for bearing both ends of the product; A part positioning component 4, the part positioning component 4 is respectively arranged at both ends of the bracket 8 for positioning the product; A profile detection component 6, the profile detection component 6 is arranged on the other side of the bracket 8 for detecting the radian of the product.

[0019] In the specific implementation process of this embodiment, as Figure 1 shown, the power device 1 is fixed on the bracket 8 through a ribbed base 9, and inside the ribbed base 9, there is a guiding groove (not marked in the figure) for controlling the direction of the upper pressing head assembly 2. The setting of the guiding groove makes the upper pressing head assembly 2 slide more smoothly up and down. Secondly, the traveling track of the upper pressing head assembly 2 is controlled through the guiding groove, improving the accuracy of shaping the profile of the anti-collision beam.

[0020] As Figure 5 shown, the lower pressing stroke limiting component 5 includes a limiting surface 51 and a limiting shaft 52. The limiting shaft 52 is arranged on the ribbed base 9, and the limiting surface 51 is arranged at the top of the limiting shaft 52 for limiting the descending stroke of the upper pressing head assembly 2.

[0021] In this embodiment, during specific use, the anti-collision beam to be shaped is placed between the limiting surface 51 and the limiting shaft 52, supported by the limiting shaft 52 on the ground, and pressed down by the limiting surface 51 above for shaping. Through this structure, over-shaping is prevented, defective products are generated, and the rejection rate is reduced.

[0022] As Figure 1As shown, a tooling substrate 7 for fixing the load-bearing support assembly 3, the part positioning assembly 4, the rib base 9, and the profile detection assembly 6 is provided on the bracket 8. The tooling substrate 7 is mainly arranged at both ends of the bracket 8 and at the position corresponding to the installation of the rib base 9. The purpose of such a setting is to facilitate placing the shaped anti-collision beam during use and secondly to facilitate the installation of each of the above components.

[0023] As Figure 2 shown, the upper pressing head assembly 2 includes an upper pressing head 24, the upper pressing head 24 is connected to the piston rod 11 of the power device 1, and limit adjusting screws 25 are provided at both ends of the upper pressing head 24; in the specific implementation process, the shaping arc of the anti-collision beam to be shaped is realized by adjusting the height of the limit adjusting screws 25.

[0024] As Figure 3 shown, the load-bearing support assembly 3 includes a fixed seat 32 fixed on the bracket 8, a support roller 33 for supporting the product is provided on the fixed seat 32, and limit plates for restricting the width of the main beam of the product are provided on both sides of the fixed seat 32.

[0025] In the specific implementation process, when the upper pressing head assembly 2 performs shaping, the two sides of the anti-collision beam are restricted by the fixed seat 32, and the support roller 33 can assist in supporting the slight movement of the anti-collision beam.

[0026] As Figure 4 shown, the part positioning assembly 4 includes a fixing plate 43 fixed on the bracket 8, the fixing plate 43 is elastically connected with a main beam length limit plate 41 for floating connection between the main beam length limit plate 41 and the product, a guide shaft 42 is provided between the fixing plate 43 and the main beam length limit plate 41, and a return spring 44 is provided on the guide shaft 42. The return spring 44 can play a limiting role while having a buffer space in cooperation with the slight movement of the anti-collision beam.

[0027] In the specific implementation process, as Figure 6 shown, the profile detection assembly 6 includes a matching surface limit detection control limit 61, a length control detection limit 62, and a radian surface height detection control limit 63. The matching surface limit detection control limit 61 and the length control detection limit 62 are arranged at both ends of the other side of the bracket 8. The length control detection limit 62 is used to limit the two ends of the product, the matching surface limit detection control limit 61 is used to limit the two surfaces of the product, and the radian surface height detection control limit 63 is used to limit the radian of the product.

[0028] By detecting the shaping result of the product through the profile detection assembly 6 and reshaping the non-conforming ones, the production of defective products in the subsequent processes is greatly reduced, and the scrap rate is greatly reduced. Through the control of the shaping mechanism, the scrap rate is less than 0.1‰, effectively reducing the manufacturing cost of the anti-collision beam.

[0029] The power device of the present invention presses down the anti-collision beam (product) until the limit is obtained when the ideal matching is achieved. The straightened anti-collision beam is subjected to a full passability test. The products that pass flow into the subsequent processes, and the products that do not meet the passability are placed aside. After the current batch is straightened, the limit is uniformly adjusted again for straightening and repair. The production of defective products in the subsequent processes is reduced, the scrap rate is reduced, and the manufacturing cost of the anti-collision beam is effectively reduced.

[0030] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
