Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, specifically to a cutting device for stainless steel pipes. Background Technology

[0002] Stainless steel pipe is a hollow, long, round steel material, widely used in industrial pipelines for petroleum, chemical, medical, food, light industry, and machinery, as well as in mechanical structural components. Additionally, it is lighter in weight while maintaining the same bending and torsional strength, making it widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used in furniture and kitchenware.

[0003] In the later processing of existing stainless steel pipes, the thinness of the stainless steel pipes in some applications can affect the roundness of the cut due to the downward pressure generated during cutting. This can lead to errors in subsequent operations such as installing sleeves. Therefore, the only solution is to reduce the cutting speed and downward pressure, but this will reduce the cutting efficiency.

[0004] Therefore, it is necessary to design a practical and fast cutting device for stainless steel pipes. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for stainless steel pipes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for stainless steel pipes, comprising a base, a cutting groove provided above the base, a pusher provided inside the cutting groove, a support tube provided at the output end of the pusher, a support frame fixedly installed on the rear side of the base, a push rod motor provided on the outer side of the support frame, a lower pressure plate provided at the output end of the push rod motor, a buffer provided below the lower pressure plate, a pressure claw provided at the bottom of the buffer, and a cutting machine slidably connected to the outer side of the lower pressure plate.

[0007] According to the above technical solution, a heightening frame is provided on the left side of the base, a conveyor belt is provided above the heightening frame, a rotating shaft is provided on the inner side of the heightening frame, a wheel is provided at the front end of the rotating shaft, and a conveying groove is provided on the inner side of the wheel.

[0008] According to the above technical solution, an outer frame is provided on the outside of the rotating shaft, a first conveyor frame is provided above the outer frame, and a second conveyor frame is provided at the bottom of the outer frame.

[0009] According to the above technical solution, a cylinder is provided on the rear side of the first conveyor frame, a collision avoidance device is provided inside the first conveyor frame, a slide rail is provided inside the first conveyor frame, a first displacement block is slidably connected below the slide rail, a first gripper is provided at the bottom of the first displacement block, a second displacement block is provided in front of the first displacement block, the second displacement block is slidably connected to the slide rail, and a second gripper is provided at the bottom of the second displacement block.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0011] (1) By setting a support tube, the steel pipe will be pushed into the cutting groove for cutting. After being pushed into the designated position, the push rod motor starts and drives the lower pressure plate to move back and forth. The position is changed according to the required cutting length. Then the buffer drives the pressure claw to descend and press the steel pipe down for simple fixation. Then the pusher will push the support tube outward and insert it into the inside of the steel pipe for the inner wall support of the steel pipe. At this time, the cutting machine descends to cut the steel pipe. Because there is support inside the support tube, the steel pipe can avoid the problem of steel pipe edge deformation caused by the cutting pressure. Thus, the cutting pressure and speed of the block cutting can be reduced, the cutting efficiency can be improved, and fast cutting can be achieved.

[0012] (2) The steel pipe is transported to the conveying trough by a rotating shaft, and then transported to the cutting trough by a transfer device. At the same time, the wheel can rotate on the rotating shaft. After the steel pipe is cut, the rotating shaft rotates and drives the wheel to rotate 180°, rotating the bottom finished product conveying trough to the top, and transferring the finished product back to the conveying trough for subsequent secondary transfer, saving the machine's floor space. The first conveying frame is used to transport the steel pipe to be cut from the conveying trough to the cutting trough. After the second conveying frame rotates to the top, it is used to send the finished steel pipe from the cutting trough to the conveying trough, realizing separate transmission and improving efficiency.

[0013] (3) By setting a first gripper and a second gripper, when the steel pipe is transported into the conveying trough, the first gripper and the second gripper descend simultaneously to grab the steel pipe. Then, by pushing the cylinder rod, the first displacement block and the second displacement block move forward, thereby realizing the transfer of the steel pipe. The second conveyor is similar, but the first gripper inside is used to grab the cutting waste, and the second gripper is used to grab the finished steel pipe, which improves the transfer efficiency.

The steel pipe is pushed into the cutting groove 2 for cutting. After being pushed into the designated position, the push rod motor 6 starts and drives the lower pressure plate 7 to move back and forth, changing its position according to the required cutting length. Then, the buffer 8 drives the pressure claw 9 to descend, pressing it down on the steel pipe for simple fixation. Then, the pusher 3 pushes the support tube 4 outward and inserts it into the inside of the steel pipe for inner wall support. At this time, the cutting machine 10 descends to cut the steel pipe. Because of the support of the support tube 4 inside, the steel pipe can avoid problems such as edge deformation caused by the cutting pressure. This can reduce the cutting pressure and speed, improve cutting efficiency, and achieve rapid cutting.

The steel pipes are transported into the conveying trough 14 and then transported into the cutting groove 2 by a transfer device. At the same time, the wheel 13 can rotate on the rotating shaft 12. After the steel pipe is cut, the rotating shaft 12 rotates and drives the wheel 13 to rotate 180°, rotating the bottom finished product conveying trough 14 to the top, and transferring the finished product back into the conveying trough 14 for subsequent secondary transfer, saving machine floor space.

[0022] An outer frame 23 is provided on the outside of the rotating shaft 12. A first conveyor frame 15 is provided above the outer frame 23, and a second conveyor frame 24 is provided at the bottom of the outer frame 23. The first conveyor frame 15 is used to transport the steel pipe to be cut from the conveying groove 14 to the cutting groove 2. After the second conveyor frame 24 rotates to the top, it is used to send the finished steel pipe from the cutting groove 2 to the conveying groove 14, so as to realize separate transmission and improve efficiency.

When the steel pipe is conveyed into the conveying trough 14, the first gripper 20 and the second gripper 22 descend simultaneously to grab the steel pipe. Then, by pushing the air rod of the cylinder 16, the first displacement block 19 and the second displacement block 21 are driven forward, thereby realizing the transfer of the steel pipe. The second conveyor frame 24 works similarly, but the first gripper 20 inside is used to grab the cutting waste, and the second gripper 22 is used to grab the finished steel pipe, which improves the transfer efficiency.
