Description

Technical Field

[0001] This utility model belongs to the technical field of steel pipe shrinking machine, and more specifically, relates to a lifting component for adjusting the height of a steel pipe shrinking machine. Background Technology

[0002] A steel pipe shrinking machine, also known as a steel pipe head shrinking machine, is a machine used to squeeze the head of a steel pipe to reduce its diameter. It uses liquid pressure to control the eight-petal seat to drive the clamps to move synchronously and squeeze the steel pipe from all directions to complete the head shrinking work.

[0003] The existing patent authorization announcement number is CN207223518U, which discloses an automatic feeding and shrinking machine, relating to the field of metal processing machinery technology. It includes a frame and a shrinking mechanism mounted on the frame. The frame also sequentially includes a feeding mechanism for storing and conveying steel pipes, a clamping mechanism for clamping and conveying steel pipes into the shrinking mechanism, and a discharging mechanism for unloading processed steel pipes. The clamping mechanism includes a support plate, which is slidably mounted on the frame towards the shrinking mechanism. A clamping drive assembly for driving the support plate to slide is mounted on the upper end face of the frame. A clamp for clamping steel pipes is rotatably mounted on the support plate. Through the coordinated operation of the clamping mechanism, the feeding mechanism, and the discharging mechanism, the feeding and unloading of the shrinking machine is automated, reducing labor intensity and improving work efficiency.

[0004] However, in existing technologies, during processing, the different sizes of steel pipes often cause the center height of the steel pipe to be processed and the steel pipe shrinking machine to be misaligned, resulting in unstable shrinking quality and large deviations in shrinking dimensions. This affects the subsequent connection and use of the steel pipe. Therefore, manual measurement and shimming operations with other tools are usually required, which is not only inefficient but also difficult to guarantee the accuracy of the adjustment, increasing the time and labor costs of production. At the same time, the existing adjustment methods lack flexibility and convenience, and cannot quickly adapt to the processing needs of steel pipes of different sizes, which to some extent limits the production efficiency and application range of the steel pipe shrinking machine.

[0028] A lifting assembly for adjusting the height of a steel pipe shortening machine includes a base 10 and a top plate 20. The base 10 is mounted on a mounting frame. The top center of the base 10 has an upward-facing and concave groove, with both ends of the groove being through-holes. The steel pipe shortening machine is placed on the top of the top plate 20. The top of the base 10 is equipped with a lifting assembly 30 for adjusting the height of the steel pipe shortening machine. The lifting assembly 30 includes a servo motor 301, a lifting mechanism 302, multiple guide columns 303, and guide sleeves 304. The servo motor 301 and the lifting mechanism 302 are both connected to the top of the base 10. The drive end of the servo motor 301 is connected to the lifting mechanism 302. The top of the lifting mechanism 302 is connected to the bottom of the top plate 20. The guide columns 303 are movably connected to the base 10, and the guide columns 303... 03 is placed at the four corners of the base 10. The top end of the guide post 303 is connected to the bottom end of the top plate 20. The guide sleeve 304 is connected to the top end of the base 10 and is located at the movable connection between the guide post 303 and the base 10. The guide post 303 and the guide sleeve 304 are movably connected. When the center height of the steel pipe shrinking machine and the steel pipe to be processed are not on the same horizontal line, the servo motor 301 drives the lifting machine 302 to move up and down, thereby driving the top plate 20 to move up and down, thereby adjusting the height position of the steel pipe shrinking machine so that the center height of the steel pipe shrinking machine and the center height of the steel pipe to be processed are on the same horizontal line. Under the action of the guide post 303 and the guide sleeve 304, the top plate 20 keeps moving parallel when moving up and down.

[0029] A speed reducer 40 is provided at the top of the base 10 near the servo motor 301. The drive end of the servo motor 301 is connected to the input end of the speed reducer 40, and the output end of the speed reducer 40 is connected to the lifting machine 302. The speed reducer 40 is used to increase the torque of the servo motor 301 so that the height of the steel pipe shrinking machine is adjusted smoothly.

[0030] A copper sleeve 50 is provided at the movable connection between the guide post 303 and the guide sleeve 304. The copper sleeve 50 is detachably connected to the guide post 303. The copper sleeve 50 is used to prevent the guide post 303 from rubbing against the guide sleeve 304 when it moves up and down.

[0031] The top of the top plate 20 is connected to a plurality of spaced and parallel shock-absorbing pads 60. The shock-absorbing pads 60 are used to absorb and disperse the vibration energy of the steel pipe shrinking machine when adjusting its height. The shock-absorbing pads 60 are made of rubber or silicone.

[0032] A stop block 70 is connected to one side of the top of the top plate 20. The stop block 70 serves as a limit. When the steel pipe to be processed moves, there is an impact force. This prevents the steel pipe shrinking machine from moving due to the impact force when it comes into contact with the steel pipe shrinking machine. The stop block 70 restricts the position of the steel pipe shrinking machine.

[0033] The stop block 70 is provided with a buffer pad 80 on the side near the steel pipe shrinking machine. The buffer pad 80 is used to reduce the impact force when the stop block 70 collides with the steel pipe shrinking machine. The buffer pad 80 is made of one of polyurethane, rubber, or silicone.

[0034] The stop block 70 is provided with a reinforcing plate 90 on the side away from the buffer pad 80 to increase the overall stability of the stop block 70.

[0035] The base 10 has multiple inspection ports 100 on both sides for easy maintenance and repair.

[0036] The beneficial effects of this utility model are as follows: This utility model proposes a lifting assembly for adjusting the height of a steel pipe shrinking machine, including a base 10 and a top plate 20. The base 10 is mounted on a mounting frame. The top center of the base 10 has an upward-facing and concave groove, with both ends of the groove being through.

The lifting assembly 30 includes a servo motor 301, a lifting mechanism 302, and multiple guide columns 303. The servo motor 301 and the lifting mechanism 302 are both connected to the top end of the base 10. The drive end of the servo motor 301 is connected to the lifting mechanism 302. The top end of the lifting mechanism 302 is connected to the bottom end of the top plate 20. The guide post 303 is movably connected to the base 10 and is located at the four corners of the base 10. The top end of the guide post 303 is connected to the bottom end of the top plate 20. The guide sleeve 304 is connected to the top end of the base 10. The guide post 303 and the base 10 are movably connected. The guide post 303 and the guide sleeve 304 are movably connected. When the center height of the steel pipe shrinking machine and the steel pipe to be processed are not on the same horizontal line, the servo motor 301 drives the lifting platform 302 to move up and down, thereby moving the top plate 20 up and down, and adjusting the height position of the steel pipe shrinking machine so that the center height of the steel pipe shrinking machine and the center height of the steel pipe to be processed are on the same horizontal line. Under the action of the guide post 303 and the guide sleeve 304, the top plate 20 keeps moving parallel when moving up and down.

Therefore, the protection scope of this utility model patent should be determined by the appended claims.
