[0002] The anti-collision beam is a device used to reduce the impact energy of the vehicle when it is hit. It consists of a main beam, an energy absorption box, and a mounting plate connected to the car. The main beam and the energy absorption box can effectively absorb the collision energy when the vehicle collides at a low speed, and minimize the damage to the longitudinal beam of the vehicle body caused by the impact force. In this way, it plays a protective role for the vehicle. The anti-collision beam of the car is located on the inner side of the bumper. It is usually stamped into a U-shaped groove from a cold-rolled steel plate and connected to the longitudinal beam of the car frame. It is an important device for absorbing and protecting the impact of the vehicle. Parts with good formability can meet the performance requirements of its anti-collision performance. At the same time, this part is a non-appearance part with high performance requirements.

[0022] like Figures 1 to 6 As shown, the present invention provides an anti-collision beam servo press brake device, including a press brake body 1, the press brake body 1 includes a frame 2, a mounting groove 3 is opened on the top of the frame 2, a main press 4 and two side presses 5 are arranged along a straight line in the mounting groove 3, and an adjustment mechanism 6 for adjusting the positions of the two side presses 5 is arranged on one side of the outer top wall of the frame 2 close to the mounting groove 3. The adjustment mechanism 6 includes a fixed frame 7, a main fixed block 8, two screws 9, two motors 10 and two mounting slide blocks 11. The fixed frame 7 is fixedly arranged on the outer top wall of the frame 2, the main fixed block 8 is fixed in the middle of the fixed frame 7, and the two screws 9 are rotatably arranged on both sides of the main fixed block 8, and the two screws 9 are away from each other. One end of the main fixed block 8 passes through the fixed frame 7 and extends to the outside of the fixed frame 7. The two motors 10 are respectively installed on both sides of the fixed frame 7, and the output shafts of the two motors 10 are respectively fixedly connected to the ends of the two screw rods 9. The two mounting slide blocks 11 are respectively sleeved on the two screw rods 9 and are respectively threadedly connected to the two screw rods 9. The two side presses 5 are respectively fixedly connected to the two mounting slide blocks 11. A positioning mold 12 is fixedly connected to the output end of the main press 4. The output ends of the two side presses 5 are fixedly provided with bending molds 13. A lower mold 14 is slidably provided on the inner bottom wall of the frame 2. The lower mold 14 is located directly below the positioning mold 12, and an anti-collision beam workpiece is placed on the lower mold 14.

[0023] The lower mold 14 includes a base 171, a placement table 172 and two limit plates 173. The base 171 is slidably set on the inner bottom wall of the frame 2 through a slide rail. The placement table 172 is fixed on the top of the base 171. The two limit plates 173 are respectively fixed at the middle positions on both sides of the placement table 172. Both sides of the top of the placement table 172 are arc-shaped. A groove 174 is opened in the middle position of the top of the placement table 172, and a magnetic attraction plate 175 is fixed inside the groove 174.

[0024] When the present invention is in use, the anti-collision beam workpiece is first placed on the lower mold 14, located between the two limit plates 173, and then the main press 4 is driven to drive the positioning mold 12 at its end to move to the top of the anti-collision beam workpiece, and squeeze it and fix it above the lower mold 14, and then the spacing between the two bending molds 13 is adjusted by the adjustment mechanism 6, and then the two side presses 5 are driven at the same time, and the two bending molds 13 are driven by the output shafts of the two side presses 5 to move down until they are in contact with the anti-collision beam workpiece. At this time, the side press 5 continues to work, driving the two bending molds 13 to bend the tops of the two ends of the anti-collision beam workpiece, and the cooperation of the adjustment mechanism 6, the positioning mold 12 and the bending mold 13 can facilitate quick It can quickly and flexibly bend anti-collision beam workpieces with different needs without frequent replacement of molds. Compared with the prior art, the existing anti-collision beam bending machine relies on the overall downward pressure of the press, and the molds at both ends of the molding have a fixed downward pressure position and a fixed downward pressure point. Each product requires a corresponding mold. Even different products with the same cross-sectional shape require different molds during molding, and even due to changes in product material over time, the mold needs to be adjusted or re-annealed. The coordination of the adjustment mechanism 6, the positioning mold 12 and the bending mold 13 in the present invention can simplify the mold design and the mold assembly adjustment time. There is no need to modify the mold, and the actual production problems caused by changes in raw material hardness and changes in molding angles can be solved.

[0025] Furthermore, the two bending dies 13 are symmetrically arranged, and the two bending dies 13 have the same structure.

[0026] The bending die 13 includes a die 131, a positioning block 132 and an extrusion plate 133. The die 131 is fixedly arranged on the output shaft of the corresponding side press 5. An L-shaped groove 134 is provided at the bottom of the die 131. The positioning block 132 is located inside the L-shaped groove 134 and is fixedly arranged at the bottom of the die 131 by bolts. The extrusion plate 133 is located below the positioning block 132. Connecting plates 135 are provided on both sides of the extrusion plate 133. A rotating shaft 136 is penetrated on the side of the inner wall of the connecting plate 135 close to the positioning block 132. The rotating shaft 136 penetrates the positioning block 132 and is rotatably connected to the positioning block 132. A sliding groove 137 is provided on the side of the inner wall of the connecting plate 135 away from the rotating shaft 136. Bumps 138 are provided on both sides of the extrusion plate 133. The bumps 138 penetrate the sliding groove 137 and are slidably connected to the sliding groove 137.

[0027] The bottom of the positioning block 132 has an arc surface 139 on one side close to the main press 4 . When the extrusion plate 133 extrudes the anti-collision beam workpiece, the extrusion plate 133 can rotate and contact the arc surface 139 at the bottom of the positioning block 132 .

[0028] When the side press 5 drives the die 131 and the positioning block 132 and the extrusion plate 133 fixed at the bottom of the die 131 to descend, the extrusion plate 133 first contacts the top of the anti-collision beam workpiece and fits on its outer top wall. When the positioning block 132 continues to press down, the extrusion plate 133 rotates while extruding the anti-collision beam workpiece, and can drive the protrusions 138 on both sides to move up and rotate along the slide groove 137 until the extrusion plate 133 rotates to contact the arc surface 139 at the bottom of the positioning block 132, so that the extrusion plate 133 is tightly attached to the anti-collision beam. On the workpiece, that is, the anti-collision beam workpiece is rotated and extruded by the extrusion plate 133, and the anti-collision beam workpiece is bent. The pressing points of the extrusion plate 133 are relatively uniform, and the force points of the anti-collision beam workpiece are relatively dispersed, thereby reducing the damage caused by extrusion. The setting of the arc surface 139 of the positioning block 132 can prevent the extrusion plate 133 from continuing to rotate after rotating to the set angle, and can disperse the downward force of the positioning block 132 when pressing down, thereby reducing the pressure on the extrusion plate 133 and the protrusions 138 on both sides thereof, thereby improving the service life of the extrusion plate 133 and the protrusions 138.

[0029] Furthermore, a connection groove is provided at one side of the bottom of the positioning block 132 , and an elastic member 140 is provided inside the connection groove. The upper and lower ends of the elastic member 140 are fixedly connected to the extrusion plate 133 and the positioning block 132 respectively.

[0030] Since the extrusion plate 133 is slidably arranged in the slide groove 137, in the initial state, the extrusion plate 133 is in an inclined state when pressed down. When the extrusion plate 133 in the inclined state abuts against the top of the anti-collision beam workpiece, as the extrusion plate 133 moves downward, it will scratch the surface of the anti-collision beam workpiece, thereby affecting the quality of the anti-collision beam workpiece. Therefore, by connecting the elastic member 140 between the extrusion plate 133 and the positioning block 132, the extrusion plate 133 is set in a parallel state when no bending work is performed, thereby avoiding scratches between the anti-collision beam workpiece, and the setting of the elastic member 140 can prevent the extrusion plate 133 from shaking when not in use.

[0031] Side grooves 15 are provided on both sides of the frame 2, and core inserting mechanisms 16 are provided in the two side grooves 15. The output shafts of the two core inserting mechanisms 16 can extend to the inner walls of the two sides of the anti-collision beam workpiece, and are adapted to the inner walls of the anti-collision beam workpiece. The two core inserting mechanisms 16 are respectively provided on both sides of the frame 2, so that the core inserting mechanisms 16 are located at the cross section of the anti-collision beam workpiece, and different cross sections of the anti-collision beam workpiece correspond to different core inserts. When the press brake is working, the core inserting mechanism 16 enters the workpiece, and the workpiece is pulled out after the anti-collision beam workpiece is press-bent and formed.

[0032] A cavity 181 is defined inside the extrusion plate 133, and a plurality of air ports 182 communicating with the cavity 181 are defined at the bottom of the extrusion plate 133, wherein a slot communicating with the cavity 181 is defined inside one of the protrusions 138, and an air pump 183 is installed on one side of the positioning block 132, and an air pipe 184 is connected to the input end of the air pump 183, and the other end of the air pipe 184 is fixedly connected to the protrusion 138 and communicated with the slot.

[0033] When the extrusion plate 133 moves down to abut against the top of the anti-collision beam workpiece, the air port 182 at the bottom of the extrusion plate 133 is blocked, and the air pump 183 is started at this time. The air inside the cavity 181 is sucked into the air pipe 184 through the air pump 183, and then discharged from the output end of the air pump 183, so that negative pressure is generated inside the cavity 181, and the anti-collision beam workpiece is adsorbed, thereby further limiting and fixing the anti-collision beam workpiece, avoiding displacement of the two ends of the anti-collision beam workpiece after the extrusion force from the extrusion plate 133, thereby avoiding the deviation of the lower pressure point when the anti-collision beam workpiece is bent, and ensuring the quality of the finished product after the anti-collision beam workpiece is bent.

[0034] Two symmetrical limit plates 173 are arranged between the two positioning blocks 132, and guide grooves are opened inside the two limit plates 173. The two ends of the rotating shaft 136 on the two positioning blocks 132 respectively pass through the guide grooves inside the two limit plates 173 and extend to the two opposite sides of the two limit plates 173. The two ends of the two rotating shafts 136 are threadedly connected with locking nuts.

[0035] The distance between the two limit plates 173 is adapted to the anti-collision beam workpiece. When the extrusion plate 133 moves downward, the two limit plates 173 can be driven to move downward synchronously to limit and correct the side wall of the anti-collision beam workpiece after bending.

[0036] This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only used to help understand the method and its core ideas of this application. The above is only the preferred implementation method of this application. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of this application, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the invention to other occasions without improvement, should be regarded as the scope of protection of this application.
