TECHNICAL FIELD
[0001] The utility model relates to automobile large -scale covering piece stamping die hoisting technology, especially to a kind of automobile large -scale covering piece stamping die hoisting device. BACKGROUND
[0002] With the development of automobile manufacturing to multi-variety, small batch and individualization, the stamping production of automobile large -scale covering piece also faces the demand of multi-variety, small batch, which leads to the replacement frequency of stamping die of automobile covering piece stamping production workshop greatly improves.Usually, the die replacement and debugging of each stamping production line per day are mostly about dozens. Since the weight and volume of the stamping die of automobile large -scale covering piece are larger, 50 tons of travelling crane is used for disassembly and hoisting.Usually, two sets of steel rings (each set is hung with 2 steel wires) are hung on the lifting hook of travelling crane, and the other four ends of steel wire are hung on the lifting bar of four corners of die respectively;Thus, die is disassembled and hoisted. Since the weight of steel wire is larger (about dozens of kilograms), in order to prevent the swing of steel wire from causing accident when travelling crane runs, steel wire needs to be stopped on one side of die before travelling crane starts, and then steel wire is thrown to four corners of die respectively when travelling crane runs above die. The above operation is completed manually by travelling crane operator, which not only has large labor intensity, but also has safety hazard. In addition, the lifting hook of travelling crane can rotate along its own axis relative to lifting seat, so that the hoisted object can be rotated as needed. Thus, when the die of prior art is disassembled and hoisted, the lifting hook rotates due to eccentric force, so that the angle of die needs to be adjusted manually after die is lifted to the set position, which also has large labor intensity and safety hazard.
[0003] Obviously, the existing automobile large -scale covering piece stamping die hoisting method has problems of not only large labor intensity, but also safety hazard. SUMMARY
[0004] To solve the problems of not only large labor intensity, but also safety hazard in the existing automobile large -scale covering piece stamping die hoisting method, the utility model provides a kind of automobile large -scale covering piece stamping die hoisting device.
[0005] This utility model relates to a hoisting device for stamping dies of large automotive body panels, comprising an angle positioning mechanism and a positioning frame. The angle positioning mechanism is disposed between the hoisting base and the hook, and includes a support frame, tension springs, and clamps. The support frame is a rectangular frame in the shape of a grid, with one end horizontally fixed to the hoisting base and the other end positioned directly in front of the opening side of the hook. Two tension springs are symmetrically arranged in a figure-eight shape directly in front of the opening side of the hook. The clamps are fitted and fixed to the end of the hook opening side. One end of each tension spring is fixed to the lower end of the support frame, and the other end is fixed to the clamp. The positioning frame is a rectangular frame, comprising a frame body, a hoisting rope, and hooks. The frame body is a rectangular frame and is suspended directly below the hook by the hoisting rope. The hooks are located at the four corners of the frame body.
[0006] Furthermore, a fall protection rope is provided between the center of the frame and the hook.
[0007] Furthermore, permanent magnets are provided at the hooks on the corners of the frame.
[0008] The beneficial technical effects of this utility model's automobile large body panel stamping die hoisting device are that it can keep the wire rope directly above the four corners of the die and keep the hook at a set angle, reducing labor intensity, eliminating safety hazards, and improving hoisting efficiency. Attached Figure Description
[0009] Appendix Figure 1 This is a three-dimensional schematic diagram of the hoisting device for stamping dies of large automotive body panels according to this utility model;
[0010] Appendix Figure 2 This is a three-dimensional schematic diagram of the angle positioning mechanism of this utility model.
[0011] In the diagram, a is the lifting seat, b is the hook, c is the wire rope; 1 is the angle positioning mechanism, 1-1 is the support frame, 1-2 is the tension spring, 1-3 is the clamp; 2 is the positioning frame, 2-1 is the frame body, 2-2 is the lifting rope, 2-3 is the hook, 2-4 is the safety rope, and 2-5 is the permanent magnet.
[0012] The following description, in conjunction with the accompanying drawings and specific embodiments, further illustrates the present invention's automobile large body panel stamping die hoisting device. Detailed Implementation
[0013] See appendix Figure 1 , 2The utility model discloses a large -scale covering piece stamping die hoisting device of car, including, angle positioning mechanism 1 and positioning frame 2, angle positioning mechanism sets up between the hanger and the hook, including, support frame 1-1, tension spring 1-2 and clamp hoop 1-3, the support frame is the vertical long rectangle frame, one end is fixed laterally on the hanger, and the other end sets up the straight front of hook opening side, the tension spring is two, and symmetry shows the eight character shape and sets up the straight front of hook opening side, the clamp hoop is fixed in the hook opening side end head, one end of tension spring is fixed in the lower end of support frame, and the other end is fixed on the clamp hoop, the positioning frame is the rectangle frame, including, frame body 2-1, sling 2-2 and hook 2-3, the frame body is the rectangle frame, and is hung in the hook straight below through the sling, the hook sets up at four corners of frame body.
[0014] As one of the preferred technical solutions, to avoid accidents, the frame body center and the hook are provided with a falling prevention safety rope 2-4. When the positioning frame appears various accidents, the safety rope can hang the frame body on the hook to prevent the frame body from falling and causing accidents.
[0015] As one of the preferred technical solutions, the hook at the corner of the frame body is provided with a permanent magnet 2-5. The combination of hooks and permanent magnets can more firmly restrict the steel wire rope at the four corners of the frame body, preventing the steel wire rope from swinging greatly during the operation of the crane. At the same time, it also ensures that the steel wire rope is just at the four corners of the mold when the crane runs above the mold.
[0016] Obviously, the automobile large covering piece stamping die hoisting device has the beneficial technical effects that the steel wire rope can be maintained directly above the four corners of the mold, the hook can be maintained at a set angle, the labor intensity is reduced, the safety hidden danger is eliminated, and the hoisting efficiency is improved.
