Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe processing, and specifically relates to a seamless steel pipe leveling device for steel structure processing. Background Art

[0002] Seamless steel pipes have hollow cross-sections and are widely used as pipelines for conveying fluids, such as pipelines for conveying oil, natural gas, coal gas, water and certain solid materials. Compared with solid steel materials such as round steel, steel pipes are lighter in weight when the bending and torsional strengths are the same. They are an economical cross-section steel material and are widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycle frames, and steel scaffolding used in construction. Using steel pipes to manufacture annular parts can improve material utilization, simplify manufacturing processes, and save materials;

[0003] When the steel pipe is in use, since the flatness of the newly produced steel pipe is uneven, the steel pipe needs to be leveled, and the existing leveling machines generally level the steel pipe by rollers, and then level a part of the steel pipe by moving the rollers back and forth. However, since the steel pipe is long, after leveling one section of the steel pipe, it is necessary to move the steel pipe to level the next section of the steel pipe, which will cause inconvenience in operation. In the prior art, it is not possible to move the steel pipe the same distance each time. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a seamless steel pipe leveling device for steel structure processing to solve the problems raised by the above background technology.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] A seamless steel pipe leveling device for steel structure processing comprises a leveling machine, a workbench is provided at the lower side of the leveling machine, and a moving mechanism is provided at the input side of the leveling machine on the workbench;

[0007] The moving mechanism includes two clamping blocks, which are slidably connected to the workbench, and a moving rod is slidably connected in the through holes opened at the lower parts of the two clamping blocks. The moving rod is connected to a reciprocating moving mechanism. A sliding sleeve is provided on the inner sides of the two clamping blocks, and a contraction spring is assembled and connected between the two sliding sleeves. A limiting plate located on the upper part of the moving rod is fixedly connected to the upper side of the workbench, and the inner sides of the two clamping blocks are slidably connected to both sides of the limiting plates. The limiting plates are wide at both ends and narrow in the middle, and the connection between the two ends and the middle is a smooth inclined surface. A limiting component is provided on the outer side of the clamping block.

[0008] Preferably, the leveling machine includes two rollers, a sliding seat, two sliding rods and a cylinder, the two rollers are assembled and connected to the upper side of the sliding seat, the two sliding rods are fixedly connected to the workbench, the sliding seat is slidably connected to the sliding rods, and the output shaft of the cylinder is assembled and connected to the sliding seat.

[0009] Preferably, the limit assembly includes a magnetic component and a control component, the magnetic component is located outside the clamping block, and electromagnet bars are assembled and connected on both sides of the workbench, and the electromagnet bars are signal-connected to the signal output end of the control component.

[0010] Preferably, the reciprocating mechanism includes a driving rod and a driving member, the driving member and the output shaft of the driving rod are transmission connected, one end of the linkage rod is hinged to the outer end of the driving rod, the other end of the linkage rod is hinged to the moving rod, and the end of the moving rod slides in a long groove fixedly connected above the workbench.

[0011] Preferably, the upper portion of the clamping block is a square block extending toward the middle portion, and an arc groove is provided in the middle portion of the square block.

[0013] Preferably, four connecting columns are connected between the limiting plate and the workbench, and the four connecting columns are located at the four corners of the limiting plate.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] The utility model is cleverly designed and can move the steel pipe the same distance each time, making it easy for the leveling machine to level the steel pipe. Through the clever design of the limit plate and the contraction spring, the clamping block can be moved along the shape of the limit plate. When the clamping block moves to the middle of the limit plate, the clamping block clamps the steel pipe and drives the steel pipe to move forward. After the steel pipe moves forward a certain distance, the clamping block separates from the steel pipe. When the clamping block moves to the position of the output end of the limit plate, the electromagnet bar is energized to adsorb the magnetic parts on both sides of the clamping block, causing the clamping block to move along the magnetic parts.

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1-3 As shown, a seamless steel pipe leveling device for steel structure processing includes a leveling machine 1, a workbench 2 is provided at the lower side of the leveling machine 1, and a moving mechanism 3 is provided at the input side of the leveling machine 1 on the workbench 2;

[0027] The moving mechanism 3 includes two clamping blocks 301, which are slidably connected to the workbench 2. A moving rod 302 is slidably connected in the through holes opened in the lower parts of the two clamping blocks 301, and the moving rod 302 is connected to the reciprocating moving mechanism 33. A sliding sleeve 303 is provided on the inner sides of the two clamping blocks 301, and a contraction spring 304 is assembled and connected between the two sliding sleeves 303. A limiting plate 305 located on the upper part of the moving rod 302 is fixedly connected to the upper side of the workbench 2. The inner sides of the two clamping blocks 301 are slidably connected to both sides of the limiting plate 305. The limiting plate 305 is wide at both ends and narrow in the middle, and the connection between the two ends and the middle is a smooth inclined surface. A limiting component 36 is provided on the outer side of the clamping block 301.

[0028] By adopting the technical solution of this embodiment, the moving rod 302 is driven to move by the reciprocating movement mechanism 33, and the moving rod 302 drives the two clamping blocks 301 to move toward the output end at the same time, the sliding sleeve 303 is fixedly connected to the clamping block 301, and is slidably connected to the moving rod 302, and the two ends of the contraction spring 304 are fixedly connected to the two sliding sleeves 303, and the contraction spring 304 contracts inwardly, and the limit plate 305 is used to make the clamping block 301 move along the edges on both sides of the limit plate 305, and the limit assembly 36 is used to make the clamping block 301 not clamp the steel pipe when the clamping block 301 is reset, and the clamping block 301 is used to clamp the steel pipe, and when the clamping block 301 moves to the middle position of the limit plate 305, the clamping block 301 clamps the steel pipe, and the clamping block 301 drives the steel pipe to move forward, and when the clamping block 301 moves to the inclined position on the output side of the limit plate 305, the clamping When the block 301 is separated from the steel pipe and the moving rod 302 reaches the end position of the output end, the reciprocating mechanism 33 starts to reset. When the reciprocating mechanism 33 is reset, the limit assembly 36 works to limit the movement trajectory of the clamp block 301, so that the clamp block 301 remains separated from the steel pipe. When the clamp block 301 is reset, the above work is repeated; the leveling machine 1 is used to level the steel pipe. The clamp block 301 is stopped at the junction of the middle part and the inclined surface on one side of the output end of the limit plate 305 through program control, so that the clamp block 301 maintains a static clamping state on the steel pipe. The leveling machine 1 levels the transported steel pipe. After the leveling machine 1 completes the leveling, the leveling machine 1 stops, and the reciprocating mechanism 33 continues to drive the moving rod 302 to move, and then repeats this process to level the unleveled steel pipe. A support block is provided on the lower side of the workbench 2.

[0029] Reference Figure 1-2 : The leveling machine 1 includes two rollers 101, a sliding seat 102, two sliding rods 103 and a cylinder 104. The two rollers 101 are assembled and connected to the upper side of the sliding seat 102, the two sliding rods 103 are fixedly connected to the workbench 2, the sliding seat 102 is slidably connected to the sliding rods 103, and the output shaft of the cylinder 104 is assembled and connected to the sliding seat 102.

[0030] In this embodiment, the cylinder 104 is used to drive the two rollers 101 to move back and forth. The movement of the cylinder 104 is controlled by a program. When the steel pipe is stationary, the output end of the cylinder moves back and forth, driving the two rollers 101 to level the steel pipe.

[0031] Reference Figure 2 The limit assembly 36 includes a magnetic component 361 and a control component 363. The magnetic component 361 is located outside the clamping block 301. Electromagnetic bars 362 are assembled and connected on both sides of the workbench 2. The electromagnetic bars 362 are connected to the signal output end of the control component 363.

[0032] In this embodiment, the control component 363 is used to control the on and off of the electromagnet bar 362. When the reciprocating mechanism 33 drives the clamping block 301 to move toward the output end, the electromagnet bar 362 is not energized, and the clamping block 301 moves along the edge of the limit plate 305 under the action of the contraction spring 304. When the reciprocating mechanism 33 drives the clamping block 301 to perform a reset movement, the control component 363 controls the electromagnet bar 362 to be energized, and the magnetic component 361 is adsorbed by the electromagnet bar 362. The adsorption force on the magnetic component 361 is greater than the elastic force of the contraction spring 304, but less than the force generated by the reciprocating mechanism 33 driving the clamping block 301 to move. Therefore, when the electromagnet bar 362 is energized, the magnetic component 361 slides along the electromagnet bar 362, and the reciprocating mechanism 33 resets the clamping block 301. At the same time, the clamping block is separated from the steel pipe. After the clamping block 301 is reset, it clamps the steel pipe again and moves toward the output end.

[0033] Reference Figure 1 and Figure 3 The reciprocating mechanism 33 includes a driving rod 331, a linkage rod 332 and a driving member 333. The driving member 333 is connected to the output shaft of the driving rod 331 by transmission. One end of the linkage rod 332 is hinged to the outer end of the driving rod 331, and the other end of the linkage rod 332 is hinged to the moving rod 302. The end of the moving rod 302 slides in a long groove 334 fixedly connected to the top of the workbench 2.

[0034] In this embodiment, the driving rod 333 controls the driving rod 331 to rotate, and when the driving rod 331 rotates, the end of the linkage rod 332 is driven to translate.

[0035] Reference Figure 2-3 The upper part of the clamping block 301 is a square block extending toward the middle, and a circular arc groove is provided in the middle of the square block.

[0036] Referring to the figure: the workbench 2 is provided with a clearance groove 335 for the driving rod 331 and the linkage rod 332 to work.

[0037] In this embodiment, the driving rod 331 and the linkage rod 332 work in the clearance groove 335 when they rotate.

[0038] Reference Figure 3 : Four connecting columns 3051 are connected between the limiting plate 305 and the workbench 2, and the four connecting columns 3051 are located at the four corners of the limiting plate 305.

[0039] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0040] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
