Description

Technical Field

[0001] The present invention relates to the technical field of automotive energy absorption boxes, and particularly to a production device and a production method for automotive energy absorption boxes. Background Art

[0002] The energy absorption box is located between the anti-collision beam and the vehicle body longitudinal beam. In the event of a collision accident, the energy absorption box can collapse and absorb energy, thereby absorbing a part of the impact force and protecting the safety of the passengers in the vehicle. The energy absorption box on the vehicle is equivalent to a sponge. The anti-collision beam is fixed at the front and rear of the vehicle head, and this component can be disassembled and replaced separately. The anti-collision beam is directly fixed to the vehicle body longitudinal beam with bolts. In the event of a minor collision accident, the anti-collision beam can protect the components on the vehicle body, thereby reducing the repair cost of the vehicle owner. In the event of a serious collision accident, the anti-collision beam can absorb a part of the impact force and transmit the impact force to the longitudinal beam. The impact force will be transmitted to the entire vehicle body through the longitudinal beam, so that the entire vehicle body can absorb and disperse the impact force. Only in this way can the safety of the passengers in the vehicle be protected. The functions of the automotive energy absorption box: The automotive energy absorption box is an important energy absorption device in the automotive bumper system and is installed between the cross beam and the vehicle frame longitudinal beam and exists as a low-speed safety protection system; when an object undergoes a strong collision, it will undergo plastic deformation, and the automotive energy absorption box can absorb a part of the impact force to protect the safety of the passengers in the vehicle; as a metal thin-walled component, the energy absorption box is prone to wrinkling and deformation during a collision. The vehicle can effectively absorb the collision energy during a low-speed collision and minimize the damage to the vehicle body caused by the impact force as much as possible. The energy absorption box not only improves the passive safety of the vehicle but also reduces the repair cost caused by the impact.

[0003] For example, the patent document with the publication number CN 101637792 B discloses a stamping forming device for the guiding groove of an automotive anti-collision bar energy absorption box to solve the forming problem of the guiding groove. Its technical solution is: it includes a core die, a core die oil cylinder, and a stamping oil cylinder. The outer shape of the core die matches the inner cavity shape of the energy absorption box and is composed of two upper and lower parts, namely the static core die located below and the moving core die located above. The interface between the upper and lower parts is a folded surface, which divides the concave die corresponding to each guiding groove into upper and lower parts; the core die oil cylinder is located above the core die, and its piston rod drives the moving core die. Four stamping oil cylinders are provided, corresponding to the guiding grooves on the four sides of the energy absorption box respectively, and each stamping oil cylinder drives a punching die matching the corresponding guiding groove. Compared with the traditional stamping device, the stamping efficiency of the present invention is high and the operation is simple. It not only ensures the quality of the energy absorption box but also reduces the production cost.

[0004] Crash safety is one of the important considerations in the design of automotive body structures. With the development of automotive lightweighting, aluminum energy-absorbing boxes have become one of the main components for vehicle anti-collision. However, the traditional energy-absorbing boxes manufactured by aluminum extrusion methods are mainly rectangular hollow walls. Such energy-absorbing boxes often experience sudden crushing during compression tests, resulting in an energy absorption effect that is much lower than the design requirements. At the same time, traditional automotive energy-absorbing box production devices usually adopt single-step production operations, and it is impossible to perform more rapid adaptation operations between production materials and production equipment. The overall production efficiency is low, and it is impossible to more efficiently complete the rapid production of energy-absorbing boxes. Moreover, traditional automotive energy-absorbing boxes cannot achieve rapid shaping operations on the contact surface of the energy-absorbing box, leading to potential quality problems with the energy-absorbing box itself. There are certain quality risks after subsequent use, which is not conducive to daily use. Therefore, there is an urgent need to design an automotive energy-absorbing box production device and its production method to solve the above problems. Summary of the Invention

[0015] A production method of an automobile energy absorption box:

[0016] S1: The energy absorption box blank is made of an aluminum square tube. The aluminum square tube can be formed by hot extrusion of wrought aluminum alloy, with low cost. The aluminum square tube is locally deformed inward to form a trapezoid-like shape at the upper part, that is, the opening of the component gradually becomes larger from top to bottom. This type of aluminum alloy can be made of 6063 series aluminum alloy. After hot extrusion, online quenching is carried out to ensure that the alloy has a certain plasticity. After plastic deformation, aging treatment is carried out.

[0017] S2: The overall processing technology is simple. The blank can be formed by hot extrusion of aluminum alloy, with low development cost. Compared with the traditional rectangular energy absorption box, when receiving a collision, the material can be deformed axially in sequence, with good energy absorption effect. The energy absorption capacity can be flexibly adjusted by changing the thickness of the blank. The energy absorption box can be formed in one step by stamping after hot extrusion of the aluminum alloy blank.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The automobile energy absorption box production device and production method thereof can realize fast and stable production operation of the energy absorption box body as a whole through the installation bar frame, motor frame, rotating frame, sleeve frame, connecting frame, processing frame, stamping frame and test frame. In actual use, the staff first preliminarily fixes the required blank for the production of the energy absorption box body inside the stamping frame, and then starts the driving motor inside the motor frame to drive the rotating frame and the sleeve frame to rotate and adjust the whole. When the processing frame rotates to the processing position of the stamping frame, the blank energy absorption box body and the energy absorption side plate are quickly combined into the main body of the energy absorption box body through the stamping frame and the supporting machinery. Then the sleeve frame rotates again to rotate the energy absorption box body as a whole inside the processing frame to the highest point, so that the energy absorption box body is in a straightened state. At this time, it is convenient for the staff to inspect the stamped energy absorption box body and classify its quality. Then the sleeve frame rotates to move the processing groove and the energy absorption box body to the test frame position, and by starting the hydraulic push rod, it drives the top pressure seat to perform energy absorption test on one end of the energy absorption box body. Finally, The working trough and the energy absorption box body as a whole enter the bottom position of the installation rack for subsequent collection work, which effectively improves the overall production efficiency of the equipment for the energy absorption box body. Through the rotation production method, the material and the equipment are directly and quickly combined, which greatly shortens the overall production line of the equipment and improves the direct management efficiency of the staff on the production line. In the production process of the energy absorption box, each production step can be more efficiently controlled to improve the production quality, help the energy absorption box to better complete the molding and testing work, and meet the daily production needs of the energy absorption box. In addition, the energy absorption box blank is made of aluminum square tubes, which can be formed by hot extrusion of deformed aluminum alloy, with low cost. The aluminum square tube is partially deformed inward to form a trapezoidal shape at the top, that is, the opening of the component gradually increases from top to bottom. This type of aluminum alloy can be made of 6063 series aluminum alloy, and online quenching is performed after hot extrusion to ensure that the alloy has a certain plasticity. After plastic deformation, aging treatment is performed to improve the strength of the material, thereby improving the ability of the parts to absorb energy, which reflects the practicality of the equipment design.

[0020] The automobile energy absorption box production device and production method thereof further improve the overall use effect of the equipment by arranging a connecting frame, an adsorption frame, a fan frame, a first triangular support frame, a second triangular support frame, a first electric slide rail, a second electric slide rail, a first sliding frame, a second sliding frame, a conveyor trough, a conveyor belt, a diffusion trough, a fan trough, a ventilation fan and an electric heating plate. In daily use, the staff can start the first electric slide rail and the second electric slide rail to adaptively adjust the first sliding frame and the second sliding frame inside each other, so that the stamping frame and the test frame can automatically cover and connect with the processing groove, thereby further improving the work efficiency of daily processing of the energy absorption box body. The daily energy absorption box body blank can be quickly adsorbed and fixed by the adsorption disk on the side of the adsorption frame. When the processing groove enters the bottom of the mounting frame, the ventilation plate is started. The fan and then the electric heating plate form upward hot air at the fan frame, which heats the energy absorption box body inside the processing groove as a whole. The heat absorption seat on the top of the adsorption frame absorbs heat, thereby heating and expanding the air inside the adsorption frame, so that the adsorption disk quickly releases the adsorption effect on the energy absorption box body, helps it to quickly leave the processing groove, and finally conveys the inner wall conveyor belt of the conveyor groove to be quickly removed from one end of the second side frame. At the same time, the overall processing technology is simple, the blank can be formed by hot extrusion of aluminum alloy, and the development cost is low. Compared with the traditional rectangular energy absorption box, when it is collided, the material can be deformed in sequence along the axial direction, and the energy absorption effect is good. The energy absorption capacity can be flexibly adjusted by changing the thickness of the blank. The energy absorption box can be formed in one step by hot extrusion of the blank from aluminum alloy and then stamping. It has high reliability and reflects the comprehensiveness of the equipment design. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] A production method of an automotive energy absorption box:

[0035] S1: The energy absorption box blank is an aluminum square tube. This aluminum square tube can be formed by hot extrusion of deformed aluminum alloy, with low cost. The local part of the aluminum square tube deforms inward to form a trapezoid-like shape at the upper part, that is, the opening of the component gradually becomes larger from top to bottom. This type of aluminum alloy can be made of 6063 series aluminum alloy, and after hot extrusion, it is quenched online to ensure that the alloy has a certain plasticity. After plastic deformation, it is then subjected to aging treatment.

[0036] S2: The overall processing technology is simple. The blank can be formed by hot extrusion of aluminum alloy, with low development cost. Compared with the traditional rectangular energy absorption box, when receiving a collision, the material can deform axially in sequence, with good energy absorption effect. The energy absorption capacity can be flexibly adjusted by changing the thickness of the blank. The energy absorption box can be formed by stamping in one step after the blank is extruded from aluminum alloy.

[0037] Working principle: When in use, the user first fixes the required blank produced by the energy absorbing box body 10 in the inside of the stamping frame 22, and then starts the driving motor 3 inside the motor frame 2 to drive the rotating frame 4 and the sleeve frame 5 to rotate and adjust the whole body. When the processing frame 8 rotates to the processing position of the stamping frame 22, the blank energy absorbing box body 10 and the energy absorbing side plate 12 are quickly combined into the main body of the energy absorbing box body 10 through the stamping frame 22 and the supporting machinery. Then the sleeve frame 5 rotates again to rotate the energy absorbing box body 10 inside the processing frame 8 to the highest point, so that the energy absorbing box body 10 is in a straightened state, which is convenient for the staff to perform the stamping. The good energy absorption box body 10 is inspected and its quality is classified. Then the sleeve frame 5 rotates to move the processing groove 9 and the energy absorption box body 10 to the test frame 24 position. By starting the hydraulic push rod 25, the top pressure seat 26 is driven to perform energy absorption test on one end of the energy absorption box body 10. Finally, the processing groove 9 and the energy absorption box body 10 enter the bottom position of the installation rack 1 as a whole for subsequent collection work, which effectively improves the overall production efficiency of the equipment for the energy absorption box body 10. By rotating the production method, the material and the instrument are directly and quickly combined, which greatly shortens the overall production line of the equipment and improves the direct management efficiency of the production line by the staff. In the production process of the energy absorbing box, each production step can be controlled more efficiently, the production quality can be improved, the energy absorbing box can be helped to better complete the molding and testing work, and the daily production needs of the energy absorbing box can be met. In the daily use process, the staff can start the first electric slide rail 19 and the second electric slide rail 20 to adaptively adjust the first sliding frame 21 and the second sliding frame 23 inside each other, so that the stamping frame 22 and the test frame 24 can be automatically connected with the processing groove 9, thereby further improving the work efficiency of the daily processing of the energy absorbing box body 10. The blank of the daily energy absorbing box body 10 can be absorbed by the side of the adsorption frame 13. The attached plate 37 performs a rapid adsorption and fixing operation. When the processing groove 9 enters the bottom of the mounting bar frame 1, the ventilation fan 35 and then the electric heating plate 36 are started, so that the two form upward hot air at the fan frame 14, and the energy absorption box body 10 inside the processing groove 9 is heated as a whole. The heat absorption seat 38 on the top of the adsorption frame 13 absorbs heat, thereby heating and expanding the air inside the adsorption frame 13, so that the adsorption plate 37 quickly releases the adsorption effect on the energy absorption box body 10, helping it to quickly leave the processing groove 9, and finally the inner wall conveyor belt 32 of the conveying groove 31 is quickly removed from one end of the second side frame 16. The above is the entire working principle of the present invention.
