Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, and more specifically, to a bracket for processing cold-rolled precision steel pipes. Background Technique

[0002] Cold-rolled seamless pipes are cold-drawn or cold-rolled precision seamless pipes used in mechanical structures and hydraulic equipment with high dimensional accuracy and good surface finish. In addition to general steel pipes, low- and medium-pressure boiler steel pipes, high-pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes, cold-rolled seamless pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, stainless thin-walled steel pipes, and special-shaped steel pipes. The outer diameter of hot-rolled seamless pipes is generally greater than 32 mm, and the wall thickness is 2.5 - 75 mm. The outer diameter of cold-rolled seamless steel pipes can reach 6 mm, and the wall thickness can reach 0.25 mm. The outer diameter of thin-walled pipes can reach 5 mm, and the wall thickness is less than 0.25 mm. Cold rolling has higher dimensional accuracy than hot rolling.

[0003] According to the common steel pipe processing brackets on the market, although there are multiple advantages, the following problems still exist: When cutting steel pipes to meet the requirements of specific lengths, traditional brackets require manual adjustment and operation, which may increase the pause time during the cutting process, thereby reducing production efficiency. Moreover, manually adjusting the size of steel pipes cannot ensure the uniformity of the cutting length, resulting in a decrease in processing accuracy. In view of this, we propose a bracket for processing cold-rolled precision steel pipes to enable automatic clamping and cutting during the processing process, and solve the problems of low production efficiency and low processing accuracy.

[0026] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0027] A bracket for processing cold-rolled precision steel pipes, comprising an assembly seat 1. At the four corners of the bottom of the assembly seat 1, mounting seats 2 are fixedly installed. Inside the mounting seats 2, a left-right threaded rod 3 is movably installed. On the surface of the left-right threaded rod 3, a moving block A 4 and a moving block B 5 are movably installed. At the top of the moving block A 4, a driving motor 6 is fixedly installed. At the top of the driving motor 6, a first clamping block 7 is threadedly connected through a rotating shaft. On the surface of the first clamping block 7, an O-shaped card slot 8 is provided. At the top of the moving block B 5, a second clamping block 9 is movably installed. Through the setting of the left-right threaded rod 3, it is convenient to synchronously control the moving block A 4 and the moving block B 5, so as to ensure that the steel pipe is clamped in the middle part of the device. Through the structural design of the first clamping block 7, the O-shaped card slot 8, and the second clamping block 9, and through the mutual cooperation between the structures, the function of stably clamping the steel pipe is realized. Thus, it can ensure that its position and posture remain stable during the cutting process, avoid cutting errors caused by the unstable position of the steel pipe, and further ensure the cutting accuracy.

[0028] Specifically, on one side of the bottom of the assembly seat 1, a stepping motor 10 is fixedly installed. On the front of the stepping motor 10, a driving gear 11 is fixedly connected through a rotating shaft. Through the structural design of the stepping motor 10 and the driving gear 11, and through the mutual cooperation between the structures, the driving function is realized. Thus, it can realize automatic feeding in cooperation with the clamping block, and the PLC can also be used to program the stepping motor 10 to control its rotation speed, so as to achieve the purpose of accurately controlling the feeding size.

[0029] Furthermore, at both ends of the left-right threaded rod 3, transmission gears 12 are fixedly installed. On the surface of the transmission gears 12, a chain 13 is movably installed. Through the structural design of the transmission gears 12 and the chain 13, and through the mutual cooperation between the structures, the transmission function is realized. Thus, the left-right threaded rods 3 on both sides can be rotated synchronously, ensuring the stability of the two sections of steel pipes after cutting, avoiding the angular displacement after cutting, and ensuring the safety of cutting processing.

[0030] It should be noted that at the four corners of the top of the assembly seat 1, moving grooves 14 are provided. In the middle part of the bottom of the assembly seat 1, a support plate 15 is threadedly connected. At the top of the support plate 15, a cylinder 16 is fixedly installed. Through the setting of the moving grooves 14, the function of limiting the moving block A 4 and the moving block B 5 is realized. Thus, it can avoid the rotation of the moving block under the rotation of the left-right threaded rod 3, and further ensure that the moving block A 4 and the moving block B 5 can move stably in a straight line.

[0031] It should be noted that a support base 17 is fixedly installed at the top of the cylinder 16 through a telescopic rod. On both sides of the top of the support base 17, limit seats 18 are fixedly installed, and arc-shaped grooves 19 are formed at the tops of the limit seats 18. Through the arrangement of the limit seats 18 and the arc-shaped grooves 19, the function of increasing the stability of the steel pipe is realized. Thus, it can ensure that the steel pipe receives uniform supporting force during the cutting process, reduce the deflection of the steel pipe during the cutting process, and avoid deformation or distortion caused by excessive local stress.

[0032] In addition, a base 20 is fixedly installed on one side of the top of the assembly seat 1, and a control arm 21 is movably installed on the top of the base 20. Through the arrangement of the control arm 21, it is convenient to control the processing angle of the cutting blade 22.

[0033] It has to be said that a cutting blade 22 is movably installed inside the control arm 21. Through the arrangement of the cutting blade 22, the function of cutting the steel pipe is realized. Thus, the length of the steel pipe can be processed to meet the requirements of a specific length.

[0034] Working principle: When using this device, the driving motor 6 drives the driving gear 11 to rotate through the rotating shaft. The driving gear 11 drives the positive and negative threaded rod 3 on one side to rotate through the transmission gear 12 on one side. At the same time, the transmission gear 12 on the other side drives the positive and negative threaded rod 3 on the other side to rotate through the chain 13. The positive and negative threaded rod 3 drives the moving block A 4 and the moving block B 5 to move inward in the opposite direction. During this period, the moving block A 4 and the moving block B 5 are limited by the moving groove 14. When the gap between the first clamping block 7 and the second clamping block 9 reaches a predetermined size, the stepping motor 10 stops working. The steel pipe is inserted into the O-shaped clamping groove 8 inside the first clamping block 7 and the second clamping block 9. The stepping motor 10 continues to work and clamps the steel pipe through the O-shaped clamping groove 8. When the first clamping block 7 and the second clamping block 9 contact the steel pipe, after providing guidance to the steel pipe through the O-shaped clamping groove 8, ensure that after the steel pipe enters the O-shaped clamping groove 8, the steel pipe is clamped through the O-shaped clamping groove 8 to ensure the stability of the steel pipe. The driving motor 6 drives the steel pipe to move and feed through the first clamping block 7. When the length reaches the predetermined size, it stops working. The cylinder 16 raises the height of the support base 17 through the telescopic rod, and provides a supporting force to both sides of the area of the steel pipe to be cut through the arc-shaped groove 19 to prevent it from deforming during the cutting process. Then, the steel pipe is cut through the cutting blade 22. During the cutting, the limit seat 18 provides support to both sides of the cutting area of the steel pipe to further ensure the stability of the steel pipe. After the steel pipe is cut, the driving motor 6 on one side drives the first clamping block 7 to rotate through the rotating shaft to export the cut steel pipe from the bracket, and the driving motor 6 on the other side drives the first clamping block 7 to rotate through the rotating shaft to import the steel pipe to be processed into the bracket for secondary cutting. By controlling the rotation speed of the driving motor 6, the feeding size of the steel pipe can be accurately controlled.
