Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts production, and relates to a lightweight side inner panel integrally forming device. Background Art

[0002] Cars are widely used daily passenger vehicles for transporting passengers, their carry-on luggage, and temporary belongings. During the car production process, the car frame usually needs to be spliced ​​and assembled with other parts. The car side inner panel is an important component of the car parts, and its manufacturing quality directly affects the appearance and performance of the car.

[0003] Automobile side inner panels are gradually being manufactured using a stamping process, in which an upper die and a lower die are used to stamp the entire metal plate. The integral molding of the entire side inner panel can ensure the strength of the vehicle body while achieving lightweight side inner panels and reducing vehicle body weight compared to welding production. However, existing side inner panels are generally fixed to the lower die by operators and removed from the lower die after stamping. The metal plate itself is heavy and inconvenient to carry, and it is easy to embed in the lower die after stamping, making it difficult to separate. Loading and unloading is cumbersome and difficult.

[0004] Based on this, we designed a lightweight one-piece molding device for the side inner panel. Utility Model Content

[0005] The purpose of this utility model is to address the above-mentioned problems in the existing technology and propose a lightweight side inner panel one-piece forming device. The technical problem to be solved by this device is: how to achieve the fixation and detachment of the workpiece when the automobile side inner panel is stamped and formed, so as to facilitate the operator to take and place the workpiece.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A lightweight one-piece forming device for a side inner panel comprises an iron workbench with an arc-shaped lower surface, support legs are arranged below the iron workbench, a frame is fixed above the iron workbench, a lower mold is fixed on the inner side of the iron workbench, a hydraulic cylinder is installed on the frame, and an upper mold is fixed to the end of the piston rod of the hydraulic cylinder, and the upper mold is located directly above the lower mold, an arc-shaped slide rail is arranged below the iron workbench, and two symmetrically distributed strong magnetic blocks are slidingly arranged on the arc-shaped slide rail, and a lifting mechanism is arranged above the strong magnetic blocks.

[0008] The lifting mechanism includes two symmetrically distributed rotating rods rotatably arranged on the frame, and a winding wheel and a gear ring are fixed on the rotating rods, a cross bar is fixed on the piston rod of the hydraulic cylinder, vertical racks are fixed at both ends of the cross bar, and the vertical racks are engaged with the gear rings at corresponding positions, a pull rope is wound around the winding wheel, two sliding seats are slidably arranged on the arc-shaped slide rail, a strong magnetic block is fixed on the sliding seat at corresponding positions, and the free end of the pull rope is connected to the sliding seat at corresponding positions.

[0009] With the above structure, when in use, when the upper mold is located at the top, the two strong magnetic blocks are located on both sides of the iron workbench, which can form a magnetic spreader (the structure and working principle of the magnetic spreader are existing technologies, and the specific principles will not be repeated here). The hydraulic cylinder drives the upper mold to move downward. At this time, the vertical rack drives the gear ring to rotate, and then drives the winding wheel to release the pull rope. At this time, under the action of gravity, the strong magnetic block moves downward, and the magnetic spreader is disbanded. Moreover, after the strong magnetic block moves to the bottom of the iron workbench, it can generate suction to the metal plate to fix the metal plate. After the stamping is completed, the hydraulic cylinder drives the upper mold to rise, and the vertical rack will drive the winding wheel to reel in the pull rope, and pull the strong magnetic block upward to form a magnetic spreader again.

[0010] An inclined support rod is provided between the upper end of the vertical rack and the cross rod.

[0011] With the above structure, when in use, the inclined support rod can provide support force to the upper end of the vertical rack, preventing it from bending after being subjected to the force of the gear ring, thereby improving the operating stability of the device.

[0012] A guide groove is provided on the outer surface of the arc-shaped slide rail, and the guide groove is aligned with the pull rope.

[0013] With the above structure, when the two strong magnetic blocks descend, the pull rope will be stretched. At this time, the pull rope will be distributed along the guide groove, fixing the trajectory of the pull rope and further improving the stability of the device.

[0014] A plurality of vertical guide rods are provided on the upper surface of the upper die, and the vertical guide rods are slidably arranged with the frame.

[0015] With the above structure, when in use, the vertical guide rod can prevent the upper die from shaking during the rising and falling process, ensure the stability of the upper die rising and falling, and improve the stamping effect.

[0016] Iron blocks are fixed on both sides of the inner wall of the iron workbench close to the strong magnetic block, and a plurality of metal soft hairs are arranged on the inner sides of the iron blocks.

[0017] With the above structure, when in use, the metal soft hair can contact the metal plate, improving the magnetization effect of the strong magnetic block on the metal plate, so that sufficient repulsive force can be formed between the metal plate and the iron workbench to lift the metal plate, thereby ensuring the actual use effect of the device.

[0018] Compared with the existing technology, this lightweight side inner panel integrated molding device has the following advantages:

[0019] 1. Through the strong magnetic block, arc-shaped slide rail, iron workbench, upper die, lower die and hydraulic cylinder, the metal plate and the stamped workpiece can be separated from the lower die before and after stamping. The operator can adjust the position of the metal plate more labor-saving, and the workpiece will not be stuck by the lower die when removing it. The loading and unloading operations are more convenient and quick, which can effectively improve production efficiency.

[0020] 2. Through the lifting mechanism, the strong magnetic block can be automatically moved during the lifting and lowering process of the upper die. The metal plate can be adsorbed and fixed by the strong magnetic block before stamping to prevent the metal plate from deflecting when subjected to the pressure of the upper die, thereby improving the stamping effect.

[0021] 3. The iron block and metal soft hair can improve the magnetic permeability between the strong magnetic block and the metal plate, enhance the magnetization effect of the magnetic block on the metal plate, so that sufficient repulsive force can be formed between the metal plate and the iron workbench to lift the metal plate, thereby ensuring the actual use effect of the device.

When the operator puts the metal plate, the metal plate contacts the metal soft bristles 12 on both sides. The two strong magnetic blocks 8 can magnetize the iron workbench 1 and the metal plate, and cause the iron workbench 1 and the metal plate to repel each other. At this time, the metal plate will float above the lower die 4, making it convenient for the operator to move its position. After determining the position of the metal plate, the hydraulic cylinder 5 drives the upper die 6 to move downward. At this time, the vertical rack 902 drives the gear ring 904 to rotate, thereby driving the winding wheel. 905 releases the pull rope 906, and the pull rope 906 moves along the track of the guide groove 909. At this time, under the action of gravity, the strong magnetic block 8 moves downward, and the magnetic spreader is disbanded. Moreover, after the strong magnetic block 8 moves to the bottom of the iron workbench 1, it can generate suction to the metal plate to fix the metal plate. After the stamping is completed, the hydraulic cylinder 5 drives the upper mold 6 to rise, and the vertical rack 902 will drive the winding wheel 905 to reel the pull rope 906 and pull the strong magnetic block 8 upward to form a magnetic spreader again, separating the formed side inner panel from the lower mold 4, making it convenient for the operator to take the material.
