Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hollow lifting hook production, in particular to a cutting device for hollow lifting hook production. BACKGROUND

[0002] The hollow lifting hook is a specially designed hoisting tool, and its hollow structure can reduce the self weight while ensuring the strength. In particular, the lifting hook made of a thin-walled pipe is widely used in many fields such as mechanical manufacturing, aerospace and medical devices due to its lightweight and certain strength characteristics. Since the hollow lifting hook is light in weight, it is easy to operate, can improve the efficiency of carrying and reduce the energy consumption of equipment. When the hollow lifting hook is produced, a cutting device is needed to cut the long pipe material into short pipe material, and then the short pipe material is subjected to bending and forming operations to form the shape of the lifting hook.

[0003] At present, when the existing cutting device cuts the thin-walled pipe, the thin-walled pipe is easily deformed at the cutting edge under the pressure applied by the saw blade and the high temperature generated during cutting. Therefore, the deformed thin-walled pipe needs to be specially corrected in the later stage. Although a long rod is usually inserted into the thin-walled pipe to prevent the thin-walled pipe from deforming during cutting as much as possible, in order to facilitate the discharging, only one end of the long rod is fixed on the cutting device, and the center of gravity of the long rod is far away from the fixed point (similar to the tail of the fishing rod held by the fisherman). Therefore, when the thin-walled pipe rotates, the long rod far away from the fixed point will shake, so that the thin-walled pipe sleeved on the outside of the long rod will also shake. Since the wall of the thin-walled pipe is relatively thin, under high-speed shaking, the pipe body will be severely deformed. SUMMARY

[0041] In the embodiment, when the pushing mechanism 4 pushes the short pipe after cutting to move to the plurality of supporting mechanisms 3, the end portion of the short pipe first contacts the first push frame 38, under the action of the pushing force of the pushing mechanism 4, the short pipe drives the first push frame 38 to move, thereby driving the two racks 35 at the position to move, the movement of the rack 35 drives the gear five 332 at the corresponding position and the threaded sleeve 33 at the corresponding position to rotate, the threaded sleeve 33 rotating can drive the screw rod 331 at the corresponding position and the clamping plate 32 to move, until the distance between the two clamping plates 32 at the first L-shaped frame 31 reaches the maximum, at this time, the short pipe drives the first push frame 38 to pass through the first L-shaped frame 31, and the rack 35 at the position is disengaged from the gear five 332 at the corresponding position, and the two racks 35 respectively move to the inclined surface of the guide rail 34 under the action of the pushing force, when the rack 35 no longer moves under the action of the pushing force, as shown in Figure 7 the middle fixed abutting block of the push frame 38 is in triangular structure at this time, at this time, the short pipe is under the action of the pushing force, and the end portion of the short pipe is lifted under the action of the triangular abutting block, and the other end of the short pipe is still in contact with the pushing mechanism 4, until the short pipe is disengaged from the push frame 38 under the action of the pushing mechanism 4 (in order to avoid the abutting block on the push frame 38 scratching the outer wall of the short pipe, the top end of the abutting block can be made of rubber), at this time, the two racks 35 at the first L-shaped frame 31 are no longer subjected to the pushing force applied by the pushing mechanism 4, so that the rack 35 reversely moves under the action of the elastic force of the elastic cord at the corresponding position and restores to the original position.
