Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe production, in particular to a steel strip butt welding auxiliary mechanism. Background Art

[0002] Special-shaped steel pipes, an indispensable structural material in the industrial sector, are defined as steel pipes with cross-sectional shapes other than circular. Due to their diverse cross-sectional shapes, such as square, rectangular, and oval, these pipes are widely used in industries such as construction, automotive, and machinery manufacturing. The production process for special-shaped, seamed steel pipes includes key steps such as steel strip preparation, unwinding, continuous rolling, welding, weld seam treatment, cutting to length, and subsequent processing.

[0003] During the unwinding process, the coiled steel strip needs to be unwound and flattened by an unwinding and flattening mechanism to facilitate subsequent processing. Since steel strips typically have a large coil diameter and length, to maintain production continuity, the previously exhausted coil must be effectively connected to the head of the new coil. In existing technology, this process typically uses two clamping assemblies to clamp the tail and head of the two coils, respectively, and then weld them together.

[0004] Although existing technologies enable continuous production, the fixed nature of the clamping assembly prevents adjustment of the position and angle between the two steel strips. This design limits the welding quality of the steel strips and affects subsequent steel pipe production. Utility Model Content

[0030] like Figures 1 to 6 As shown, a steel strip butt welding auxiliary mechanism in an embodiment of the present invention includes a base 100, a front clamping assembly 200, and a rear clamping assembly 300 disposed behind the front clamping assembly 200. In practice, the steel strip butt welding auxiliary mechanism of the present invention is installed on a production line for special-shaped seamed steel pipes via the base 100. After the tail and head of the two rolls of steel strip are sheared, the front clamping assembly 200 is used to clamp the tail of the previous roll of steel strip, and the rear clamping assembly 300 is used to clamp the head of the next roll of steel strip, thereby assisting in welding the tail and head of the two rolls of steel strip.

[0031] The front clamping assembly 200 includes a front pressure plate 210, a slide 220 connected to the base 100 for sliding back and forth, a position adjustment device 230 installed on the base 100 for changing the front and rear position of the slide 220, a swing seat 240 hinged to the slide 220, an angle adjustment device 250 installed on the slide 220 for changing the angle of the swing seat 240, and a front clamping drive device 260 installed on the swing seat 240 for driving the front pressure plate 210 to cooperate with the swing seat 240 to clamp the steel belt. In fact, since the front clamping drive device 260 is installed on the swing seat 240, the front clamping drive device 260 moves forward and backward synchronously with the swing seat 240 and can change the angle relative to the slide 220. The front clamping drive device 260 can be a cylinder, a hydraulic cylinder, etc., which can drive the front pressure plate 210 to move up and down to clamp the steel belt passing through the front pressure plate 210 and the swing seat 240; the position adjustment device 230 can be a servo hydraulic cylinder, a screw slider and a driving component, etc., which can It can drive the slide 220 to move forward and backward to change the forward and backward positions of the pendulum seat 240 and the front pressure plate 210, that is, it can change the forward and backward position of the steel belt clamped between the pendulum seat 240 and the front pressure plate 210; the angle adjustment device 250 can be one of an angle motor, a worm gear and a turbine driving component, etc., which can drive the pendulum seat 240 together with the front clamping drive device 260 and the front clamp to swing synchronously, that is, it can change the angle of the steel belt clamped between the pendulum seat 240 and the front pressure plate 210 relative to the base 100.

[0032] The rear clamping assembly 300 includes a rear pressure plate 310 and a rear clamping drive 320 mounted on the base 100 for driving the rear pressure plate to cooperate with the base 100 to clamp the steel strip. In practice, the rear clamping drive 320 can be a pneumatic cylinder, a hydraulic cylinder, etc., capable of driving the rear pressure plate 310 to move up and down to clamp the steel strip passing through the rear pressure plate 310 and the base 100.

[0033] The specific working steps of the steel strip butt welding auxiliary mechanism of the present invention are as follows: initially, the front pressure plate 210 and the rear pressure plate 310 are in the upper position, respectively making the rear part of the previous roll of steel strip pass through between the front pressure plate 210 and the swing seat 240 and the front part of the next roll of steel strip pass through between the rear pressure plate 310 and the base 100; the front clamping drive device 260 drives the front pressure plate 210 to move, so that the front pressure plate 210 cooperates with the swing seat 240 to clamp the rear part of the previous roll of steel strip, and the rear clamping drive device 320 drives the rear pressure plate 310 to move, so that the rear pressure plate 310 cooperates with the base 100 to clamp the front part of the next roll of steel strip; operating the position adjustment device 230 and the angle adjustment device 250, the front and rear position of the rear part of the previous roll of steel strip clamped between the front pressure plate 210 and the swing seat 240 and the angle relative to the base 100 can be adjusted, that is, the front and rear position and angle of the rear part of the previous roll of steel strip relative to the front part of the next roll of steel strip can be adjusted.

[0034] The steel strip butt welding auxiliary mechanism of the present invention is used to obtain a better welding position and angle. The base 100, the front clamping assembly 200 and the rear clamping assembly 300 cooperate with each other to adjust the front and rear position and angle of the rear part of the previous roll of steel strip relative to the front part of the next roll of steel strip, thereby improving the welding quality of the steel strip and reducing the impact on subsequent steel pipe production.

[0035] Specifically, the front portion of the base 100 is provided with a stepped surface 110 for accommodating the front clamping assembly 200. The upper side of the pendulum seat 240 is preferably coplanar with the upper side of the base 100. In practice, for production consistency, the thickness of the rear portion of the preceding steel strip and the front portion of the succeeding steel strip are equal. The coplanarity of the upper side of the pendulum seat 240 and the upper side of the base 100 ensures that when the front pressure plate 210 cooperates with the pendulum seat 240 to clamp the rear portion of the preceding steel strip, and when the rear pressure plate 310 cooperates with the base 100 to clamp the front portion of the succeeding steel strip, the rear portion of the preceding steel strip and the front portion of the succeeding steel strip are at the same height, further improving the welding quality of the steel strips.

[0036] More specifically, the front portion of the base 100 is preferably provided with two slide rails 120 spaced apart and connected to the slide 220 for forward and backward sliding. Figure 1 、 Figure 2 and Figure 4 As shown, the slide 220 can be provided with two slide grooves spaced apart on the left and right and matching the slide rail 120 to achieve a forward and backward sliding connection with the slide rail 120 . The slide 220 is connected to the slide rail 120 to achieve a forward and backward sliding connection with the base 100 .

[0037] Furthermore, the base 100 is preferably provided with a mounting groove 130 between the two slide rails 120, and the position adjustment device 230 is installed in the mounting groove 130. By installing the position adjustment device 230 in the mounting groove 130, space is provided for the installation of the position adjustment device 230, and the position adjustment device 230 is prevented from affecting the two slide rails 120.

[0038] Furthermore, the position adjustment device 230 preferably includes a first self-locking screw 231 disposed within the mounting slot 130 and rotatably connected to the base 100, and a first adjustment wheel 232 fixed to the left end of the first self-locking screw 231. The first self-locking screw 231 extends forward and backward and is threadedly connected to the slide 220. In practice, when the slide 220 is subjected to external force, the threaded connection between the first self-locking screw 231 and the slide 220 self-locks, preventing the slide 220 from moving left or right, thereby ensuring the accurate positioning of the slide 220. By rotating the first adjustment wheel 232, the operator can drive the first self-locking screw 231 to rotate, thereby driving the slide 220 to move forward and backward, thereby changing the front-to-back position of the slide 220.

[0039] Furthermore, the left part of the pendulum seat 240 is hinged to the slide 220, and the angle adjustment device 250 preferably includes a second self-locking screw 251 rotatably connected to the slide 220, a second adjustment wheel 252 fixed to the left end of the first self-locking screw 231, and a first slider 235 connected to the slide 220 for sliding back and forth. The second self-locking screw 251 extends forward and backward and is threadedly connected to the first slider 235, and the right part of the pendulum seat 240 is hinged with a second slider 241 connected to the first slider 235 for sliding left and right. In fact, when the first slider 235 is subjected to external force, the threaded connection between the second self-locking screw 251 and the first slider 235 will prevent the first slider 235 from moving left and right under the self-locking effect, ensuring the positioning accuracy of the first slider 235; during operation, the operator can rotate the second adjusting wheel 252 to drive the second self-locking screw 251 to rotate, thereby driving the first slider 235 to move back and forth. When the first slider 235 moves back and forth, it will drive the second slider 241 to move back and forth, and under the restriction of the pendulum seat 240, the second slider 241 slides left and right relative to the first slider 235. Therefore, the hinge point between the second slider 241 and the pendulum seat 240 swings relative to the hinge point between the pendulum seat 240 and the slide 220, thereby realizing the swing of the pendulum seat 240, so as to adjust the swing of the pendulum seat 240 and the front clamping drive device 260 installed on the pendulum seat 240. It should be noted that, if Figure 3 As shown, the swing seat 240 is provided with a space for the second slider 241 to swing, as shown in FIG. Figure 5 As shown, the slide 220 is provided with a clearance space for the front clamping drive device 260 to swing, ensuring that the swing seat 240 and the front clamping drive device 260 can adjust the angle within a certain range, reducing the mutual interference between the swing seat 240 and the second slider 241 and the mutual interference between the slide 220 and the front clamping drive device 260 when adjusting the angle.

[0040] It should be noted that the front clamping drive device 260 is mounted on the lower side of the swing seat 240 and is preferably provided with two first drive rods 261 extending from the upper side of the swing seat 240, and the front pressure plate 210 is mounted on the first drive rods 261. Figure 5 As shown, the pendulum seat 240 is provided with two through holes corresponding to the first drive rod 261 passing through, so that the pendulum seat 240, the front pressure plate 210 and the front clamping drive device 260 swing synchronously, and the front clamping drive device 260 drives the front pressure plate 210 to move up and down to realize that the front pressure plate 210 cooperates with the pendulum seat 240 to clamp the steel plate; the rear clamping drive device 320 is installed on the base 100 and is preferably provided with two drive rods extending upward from the upper side of the base 100, and the rear pressure plate 310 is installed on the second drive rod 321, so that the rear progressive drive device drives the rear pressure plate 310 to move up and down to realize that the rear pressure plate 310 cooperates with the base 100 to clamp the steel plate.

[0041] Further, such as Figure 1 As shown, the two first driving rods 261 are preferably located behind the hinge point between the left part of the pendulum seat 240 and the slide 220 and the right part of the pendulum seat 240 and the second slider 241, leaving more space for the steel plate to pass between the two first driving rods 261 and through the hinge point between the left part of the pendulum seat 240 and the slide 220 and the right part of the pendulum seat 240.

[0042] It is worth mentioning that the front pressure plate 210 is preferably provided with two first through holes 211 corresponding to the first drive rods 261. The lower portion of the first drive rod 261 is a first round rod 262 having an outer diameter larger than the first through hole 211, and the upper portion is a first screw 263 having an outer diameter smaller than the first through hole 211. The first screw 263 is threadedly connected to a first nut 264 for abutting against the upper side of the front pressure plate 210. In practice, the first nut 264 cooperates with the upper end of the first round rod 262 to clamp the front pressure plate 210, thereby achieving the connection between the front pressure plate 210 and the first drive rod 261, and the front pressure plate 210 can be replaced as needed. The rear pressure plate 310 is provided with two second through-holes 311 corresponding to the second drive rods 321. The lower portion of the second drive rod 321 is a second round rod 322 with a larger outer diameter than the second through-hole 311, and the upper portion is a second screw 323 with a smaller outer diameter than the second through-hole 311. The second screw 323 is threadedly connected to a second nut 324 that abuts against the upper side of the front pressure plate 210. In practice, the second nut 324 cooperates with the upper end of the second round rod 322 to clamp the rear pressure plate 310, thereby achieving the connection between the rear pressure plate 310 and the second drive rods 321, and allowing the rear pressure plate 310 to be replaced as needed.

[0043] The above are only specific embodiments of the present invention and do not limit the patent scope of the present invention. For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the present invention.
