[0003] During the bending process, the front bumper frame and the bending die will make hard contact. The product has high frictional resistance with the outer wall of the bending die, which can easily cause wear on the outer wall of the front bumper frame and the surface of the bending die, affecting the product quality of the front bumper frame. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a front bumper frame bending device that solves the problem of high frictional resistance and easy wear on the outer wall of the bending die and the outer wall of the product during bending.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1 to 2 This embodiment provides a front bumper frame bending device, including a mounting platform 1. A bending component 2 is installed on one side of the top surface of the mounting platform 1, which is the prior art. The bending component 2 consists of a bending die and a linear moving structure. By using the linear moving structure, the movable bending die moves towards the fixed bending die, and the bumper frame between the bending dies is bent.

[0019] An oil storage tank 3 is installed on the side of the mounting platform 1 away from the bending component 2. A baffle plate 15 is fixed to the upper end of the inner wall of the oil storage tank 3. A through groove 13 is opened on the baffle plate 15 directly opposite the arc part. Several drain combs 14 are fixed at equal intervals on the inner wall of the through groove 13.

[0020] An electric push rod 8 is fixed on the top surface of the mounting platform 1 between the bending assembly 2 and the oil storage tank 3. A lifting plate 4 is fixed to the extended end of the electric push rod 8. A guide rod 9 is symmetrically fixed to the bottom surface of the lifting plate 4. The guide rod 9 is slidably connected to the mounting platform 1 through a sliding hole. A support frame 5 is rotatably mounted on the top surface of the lifting plate 4. A rotating shaft 7 is fixed to one end of the support frame 5 near the lifting plate 4. The lower end of the rotating shaft 7 is rotatably connected to the lifting plate 4. The end of the support frame 5 away from the lifting plate 4 forms a downward-bent arc-shaped part. The shape of the arc-shaped part is adapted to the shape of the bending die of the bending assembly 2. A sponge 6 is provided on the circumferential outer wall of the arc-shaped part. A worm gear 11 is fixed to the outer wall of the rotating shaft 7. A worm 10 is rotatably connected to the top surface of the lifting plate 4. The worm 10 is meshed with the worm gear 11. A motor 12 is fixed on the top surface of the lifting plate 4. The output end of the motor 12 is fixed to one end of the worm 10.

[0021] In use, the front bumper frame is placed between the bending dies of the bending assembly 2, and the linear movement structure in the bending assembly 2 is driven to make the bending dies align and bend the bumper; lubricating oil is applied between the bending dies periodically to reduce friction between the bumper and the bending dies.

[0022] The electric push rod 8 drives the lifting plate 4 to rise and fall. The guide rod 9 ensures the stability of the lifting plate 4. The rise and fall of the lifting plate 4 drives the support frame 5 to rise and fall, which in turn drives the sponge 6 to rise and fall. The drive motor 12 causes the worm gear 10 to rotate and turn the worm wheel 11, so the rotating shaft 7 rotates and the support frame 5 rotates accordingly. This allows the sponge 6 to rotate and be positioned above the oil tank 3 or above the bending die. When the sponge 6 is above the oil tank 3, the electric push rod 8 retracts, and the sponge 6 enters the oil tank 3 through the through groove 13 to absorb lubricating oil. When the electric push rod 8 extends, the sponge 6 moves upward and away from the oil tank 3. The sponge 6 is squeezed by the drain comb 14 to drain excess oil, and then the sponge 6 rotates to be above the bending die. Then the electric push rod 8 retracts again, and the sponge 6 moves between the two bending dies, causing the moving bending die to move towards the fixed bending die until both bending dies are in contact with the outer wall of the sponge 6 and squeeze out some lubricating oil. At this time, the bending die is lubricated by the lubricating oil in the sponge 6.

[0023] Then the electric push rod 8 extends again, moving the sponge 6 above the bending die. The drive motor 12 rotates the sponge 6 to one side of the oil tank 3, so as not to hinder the loading of the bumper frame.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
