In order to absorb as much collision kinetic energy as possible, the bumper system is designed with a collision energy absorption box to absorb collision kinetic energy by means of crush deformation, thereby ensuring the safety of the vehicle occupants and the main structure of the vehicle body. The existing automobile crush box is often provided with energy absorption ribs on both sides of the cuboid box body. The processing process is to directly form an initial shape by forging and pressing, and then to be welded by a closing plate. However, the energy absorption effect of the one-piece crush box is not obvious in non-forward low-speed collision.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in conjunction with specific embodiments.

[0019] As shown in Figs. 1 to 4 A processing equipment for automobile crush box, comprising base 1, putting table 2, assembly mechanism 3 and shaping mechanism 4, the putting table 2 is arranged on the base 1, the assembly type crush box 6 is placed on the putting table 2 through the guide convex 5, the assembly mechanism 3 is installed on the base 1 and is used for completing the assembly of the assembly type crush box 6, and the shaping mechanism 4 is installed on the putting table 2 and is used for completing the shaping of the assembly process of the assembly type crush box 6.

[0020] In the embodiment, the assembly mechanism 3 comprises cylinder 301, jacking frame 302 and pressing plate 303, the cylinder 301 is installed on the base 1 through mounting frame 304, the output end of the cylinder 301 is provided with lifting frame 305, two symmetrical guide columns 306 are installed on the mounting frame 304, the lifting frame 305 is slidably arranged on the guide column 306, a plurality of articulated pull plates 307 are uniformly arranged on the lower end of the lifting frame 305, the lower end of the pull plate 307 is articulated with the sliding plate 308, the opening guide plate 309 is installed on the base 1, the sliding plate 308 is slidably arranged on the opening guide plate 309, and the pressing plate 303 is detachably installed on the end of the sliding plate 308, and the jacking frame 302 is arranged on the putting table 2.

[0021] It should be noted that when the output end of the cylinder 301 is fully extended, the assembly type crush box 6 reaches the assembly limit position, and the jacking frame 302 and the pressing plate 303 are in.

[0022] In the embodiment, the pressing plate 303 and the jacking frame 302 are arranged on both sides of the putting table 2 respectively, and the end faces matched with the two sides of the assembly type crush box 6 are respectively provided with plugs, the plugs can be directly placed into the plug-in holes on the assembly type crush box 6 to complete the preliminary positioning operation.

[0023] In this embodiment, the shaping mechanism 4 includes a U-shaped isolation groove 401, a pusher 402, and a shaping block 403. There are several U-shaped isolation grooves 401, which are evenly distributed on the platform 2. The pusher 402 is installed at the lower end of the push-pull plate 307, and the pusher 402 also has a clearance member 404 installed through the open guide plate 309. A trapezoidal top block 405 is detachably installed on the clearance member 404. The clearance member 404 is slidably disposed in the U-shaped isolation groove 401. The shaping block 403 is symmetrically and movably disposed on both sides of the U-shaped isolation groove 401. The two shaping blocks 403 in the U-shaped isolation groove 401 are connected by a tension spring 406. The trapezoidal top block 405 cooperates with the back plane of the shaping block 403, and there is no rigid contact between the trapezoidal top block 405 and the tension spring 406.

[0024] In addition, the assembled crumple box 6 is composed of crumple ribs 61 and energy-absorbing assembly frame 62.

[0025] It should be noted that the front of the shaping block 403 has an interlocking surface structure that matches the collapsible concave-convex rib 61.

[0026] Working process and principle: In the process of using this invention, firstly, a collapsible concave-convex rib 61 is placed on the top support frame 302. The collapsible concave-convex rib 61 is directly inserted into the plug on the top support frame 302 through the insertion hole on the collapsible concave-convex rib 61 to complete the pre-positioning of the collapsible concave-convex rib 61. Then, under the guidance of the guide protrusion 5, the energy-absorbing assembly frame 62 is placed. Then, the cylinder 301 is started so that its output end drives the lifting frame 305 to move up and down the guide column 306. The sliding plate 308 is pushed by the push-pull plate 307 to slide on the open guide plate 309, which in turn drives the pressing plate 303 to push the energy-absorbing assembly frame 62 until the output end of the cylinder 301 is fully extended to complete the assembly operation between the multiple energy-absorbing assembly frames 62 and the collapsible concave-convex rib 61 on the platform 2.

[0027] While the sliding plate 308 slides, it also drives the pusher 402 to slide synchronously in the opening of the guide plate 309. During the sliding process of the avoidance part 404, it drives the trapezoidal top block 405 to complete synchronous sliding in the U-shaped isolation groove 401. After the inclined ends on both sides of the trapezoidal top block 405 pass through the shaping blocks 403 on both sides of the U-shaped isolation groove 401, they will push the two shaping blocks 403 out from both sides of the U-shaped isolation groove 401, so that the front of the shaping block 403 abuts against the concave and convex surfaces of the collapse concave and convex rib 61, thereby preventing the collapse concave and convex rib 61 and the energy-absorbing assembly frame 62 from deforming during the assembly process. At this time, the tension spring 406 is in an elastic tension state.

[0028] After the collapsible ribs 61 and the energy-absorbing assembly frame 62 are assembled, the reverse start cylinder 301 resets its output end. At the same time, when the pressure plate 303 loses its pressing effect on the assembled collapsible box 6, the tension spring 406 will also pull the shaping blocks 403 on both sides to reset under its own elasticity, thus preparing for the assembly operation of the next batch of assembled collapsible boxes 6.

[0029] Based on the above, the present invention sets an assembly mechanism 3 and a shaping mechanism 4 on the base 1 and the platform 2. The output end of the cylinder 301 drives the lifting frame 305 to move up and down the guide column 306. The sliding plate 308 is pushed by the push-pull plate 307 to slide on the open guide plate 309, which in turn drives the pressing plate 303 to push the energy-absorbing assembly frame 62 until the output end of the cylinder 301 is fully extended, so as to complete the assembly operation between multiple energy-absorbing assembly frames 62 and the collapsible concave and convex ribs 61 on the platform 2. By processing the assembly-type collapsible box 6 through the separate assembly method, in the case of non-positive low-speed collision in application, the energy-absorbing assembly frame 62 first undergoes preliminary energy-absorbing deformation. After reaching the deformation limit, the collapsible concave and convex ribs 61 then progressively deform to absorb energy. The energy absorption effect is obvious and the collision damage is reduced.

[0030] While the sliding plate 308 slides, it drives the trapezoidal top block 405 to slide synchronously in the U-shaped isolation groove 401. The front of the shaping block 403 abuts against the interlaced surface of the collapsible concave-convex rib 61, thereby preventing the collapsible concave-convex rib 61 and the energy-absorbing assembly frame 62 from deforming during the assembly process and ensuring the quality of the assembled products.

[0031] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
