Description

Technical Field

[0001] The present invention belongs to the technical field related to steel pipe cutting processing, and in particular relates to a pipe pressing device for steel pipe cutting and a use method thereof. Background Art

[0002] In the field of steel pipe processing, such as construction, machinery manufacturing, pipeline engineering, etc., steel pipe cutting is a basic and high-frequency process. In order to ensure cutting quality (smooth cut and accurate size), improve efficiency and ensure operational safety, it is crucial to reliably and stably clamp and fix the steel pipe during the cutting process. Steel pipes that are not effectively fixed are very likely to roll, jump or axially move when subjected to cutting forces (such as sawing vibration, flame / plasma cutting impact, etc.). This will not only lead to uneven cutting surfaces and dimensional deviations, resulting in material waste and rework, but also accelerate the wear and even damage of cutting tools or cutting consumables (such as saw blades and cutting nozzles), and may even cause major safety accidents such as steel pipe flying off, posing a serious threat to operators and equipment. According to the existing public document CN113909555B, in order to ensure the stability of the steel pipe, a corresponding pipe pressing device will be used to ensure the stability of the steel pipe position and avoid excessive displacement of the steel pipe.

[0003] Therefore, most of the currently used pipe pressing devices use pneumatic methods to compress steel pipes. This method requires manual control of the opening and closing of the pneumatic structure, which is prone to misoperation and may not compress the steel pipe immediately, resulting in the inability to cut the steel pipe normally. At the same time, when pressing the steel pipe, most of the currently used pipe pressing devices use a top-down compression method. However, steel pipes come in square, ring, or special shapes. When this compression method is used on ring-shaped steel pipes, the steel pipes roll due to rotation, and the existing devices lack a limiting function for the side walls of the steel pipes. Therefore, the steel pipes are prone to tilting and deviating during the transportation and cutting process, thereby affecting the cutting quality of the steel pipes. To this end, we provide a pipe pressing device for steel pipe cutting and a method of use to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a pipe pressing device for steel pipe cutting and a method of use. By retracting the rope with a retracting roller, the main positioning plate is controlled to press the steel pipe, and the steel pipe is automatically pressed in a mechanical manner to ensure the stability of steel pipe cutting. At the same time, through the coordinated use of the main positioning plate and the inclined splint, the inclined splint rotates along the side of the main positioning plate and presses the side wall of the steel pipe, thereby increasing the clamping strength of the steel pipe and avoiding the displacement of the steel pipe. In addition, the coordinated use of the calibration spring, calibration plate and mounting plate can achieve the function of pressing steel pipes of different sizes.

[0008] The present invention is further configured such that the end faces of the slide bars passing through the adjustment openings are bolted with locking strips, and the locking strips are connected to the side walls of the adjustment plate, and the limiting rods located below the slide bars are sleeved with return springs.

[0009] The present invention is further configured such that the calibration bar fixed on the left side wall of the calibration plate is located in the adjustment opening in the middle of the adjustment plate, the protrusion fixed on the end face of the calibration bar is connected to the left side wall of the adjustment plate, and the front and rear side walls of the adjustment plate are fixed with support plates connected to the external cutting equipment with bolts.

[0010] The present invention is further configured such that the upper and lower ends of the calibration spring are fixed with abutment rings respectively connected to the end faces of the calibration plate and the mounting plate; the upper end face of the calibration plate is fixed with a positioning rod passing through the abutment ring and the inside of the calibration spring; a positioning hole is penetrated through the side wall of the mounting plate corresponding to the positioning rod; the upper end face of the positioning rod is inserted into the positioning hole; a circular plate is provided at the position of the upper end face of the mounting plate corresponding to the positioning hole; the circular plate is bolted to the upper end face of the positioning rod by bolts; the side wall of the mounting plate is fixed with a limit strip bolted to the side wall of the adjustment plate.

[0011] The present invention is further configured such that the front and rear side walls of the diagonal plate on the right side of the furling roller are both provided with stretching holes connected to the inner opening of the diagonal plate, and one end of the two ropes are respectively inserted into the inner opening of the diagonal plate from the opening positions of the corresponding stretching holes.

[0012] The present invention is further configured such that the front and rear side walls of the diagonal plate located on the left side of the stretching hole are bolted with bending bars, and the rope passes over the outer side of the shaft tube of the bending bar; the front and rear sides of the diagonal plate located on the left side of the bending bar are bolted with right-angle bars, and the rope passes over the outer side of the shaft tube of the right-angle bar from above; an auxiliary bar is bolted in the inner mouth of the diagonal plate located on the right side of the furling roller, and the two ropes pass through the position between the two groups of auxiliary bars.

[0015] The present invention also provides a method for using a pipe pressing device for steel pipe cutting, which is operated according to the following steps:

[0016] S1: The entire device is installed directly above the conveying structure of the steel pipe cutting equipment. Therefore, when the steel pipe is placed on the conveying structure, the conveying structure pushes the steel pipe to move, thereby moving the steel pipe to the position below the diagonal plate;

[0017] S2: When the steel pipe moves to the surface of the retracting roller, the friction between the retracting roller and the steel pipe causes the movement of the steel pipe to drive the retracting roller to rotate, and then the retracting roller retracts the rope, and then the rope pulls the square plate downward and controls the sliding plate to move downward synchronously;

[0018] S3: After the previous step, the sliding plate will drive the main positioning plate and the inclined clamping plate to move downward, controlling the main positioning plate to abut against the surface of the steel pipe. Therefore, as the retraction roller continues to retract, the sliding plate will continue to move downward synchronously.

[0019] S4: At this time, the main positioning plate stops moving, thereby shortening the distance between the compression rod and the sliding plate, and controlling the linkage rod to move downward, and then the linkage rod pushes the inclined splint to tilt and rotate, thereby controlling the two sets of inclined splints to clamp the steel pipe and press the steel pipe.

[0020] The present invention has the following beneficial effects:

[0021] 1. After the steel pipe is connected to the gathering roller, the movement of the steel pipe will drive the gathering roller to rotate, so that the gathering roller will gather the rope, and thereby drive the sliding plate and the main positioning plate to move downward. When the main positioning plate presses the steel pipe, it will perform preliminary positioning of the steel pipe to prevent the steel pipe from shaking and vibrating during the cutting process. At the same time, the gathering roller rotates with the movement of the steel pipe, realizing the role of autonomously pressing the steel pipe in a mechanical way.

[0022] 2. The linkage rod moves downward, and the linkage rod will push the U-shaped frame, so that the linkage sleeve and the U-shaped frame rotate with each other, and will control the U-shaped frame to slide along the inclined splint, and will push the inclined splint to rotate. The inclined splint rotates along the side of the main positioning plate and presses the side wall of the steel pipe, thereby increasing the pressing strength of the steel pipe, avoiding the deviation of the steel pipe, and ensuring the reliability of pressing the steel pipe.

[0023] 3. When steel pipes of different sizes pass through the lower position of the diagonal plate, the steel pipes of different sizes will move the diagonal plate upward, and the diagonal plate will move upward and control the calibration plate to compress the calibration spring. The calibration spring pushes downward, so that the diagonal plate always controls the gathering roller to connect with the surface side of the steel pipe, thereby achieving the effect of pressing steel pipes of different sizes.

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention. Example 1

[0038] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4、 Figure 6 and Figure 8 , which is the first embodiment of the present invention, provides a pipe pressing device for steel pipe cutting, which controls the main positioning plate 501 to press the steel pipe by the retraction roller 205 to retract the rope 402, thereby realizing the function of automatically pressing the steel pipe in a mechanical manner, thereby ensuring the stability of steel pipe cutting, and at the same time, through the coordinated use of the main positioning plate 501 and the inclined clamping plate 502, the inclined clamping plate 502 rotates along the side of the main positioning plate and presses the side wall of the steel pipe, thereby improving the pressing strength of the steel pipe and avoiding the displacement of the steel pipe, and the coordinated use of the calibration spring 207, the calibration plate 206 and the mounting plate 301 can realize the function of pressing steel pipes of different sizes.

[0039] Specifically, the assembly component 100 includes an adjustment plate 101 located directly above the steel pipe, a linkage calibration component 200 including a diagonal plate 201 located at the lower right position of the adjustment plate 101 and a retracting roller 205 located at the opening position of the diagonal plate 201, a mounting component 300 including a mounting plate 301 located directly above the calibration plate 206, a sliding component 400 including a sliding plate 401 located at the upper left side of the adjustment plate 101, two ropes 402 located at the front and rear positions of the sliding plate 401, and a rotating cylinder 403 sleeved on the retracting roller 205, and a pipe pressing positioning component 500 including a main positioning plate 501 located directly below the sliding plate 401 and inclined clamping plates 502 located at the front and rear sides of the main positioning plate 501;

[0040] Through the arrangement and use of the above-mentioned structure, the steel pipe passes through the lower position of the gathering roller 205, thereby the steel pipe will drive the gathering roller 205 to rotate, thereby the gathering roller 205 gathers the rope 402, and thereby drives the sliding plate 401 to move downward, thereby controlling the main positioning plate 501 to press the steel pipe, so that when the steel pipe is cut again, the amplitude of the steel pipe vibration is reduced, and at the same time the inclined clamping plate 502 will press the side of the steel pipe, which can avoid the steel pipe from being cut off-center and improve the overall compression of the steel pipe.

[0041] according to Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8The upper end surface of the diagonal plate 201 is fixed with a T-shaped calibration plate 206, and the upper end surface of the calibration plate 206 is provided with a calibration spring 207 used in conjunction with the mounting plate 301. The middle position of the front and rear sides of the sliding plate 401 is fixed with a square plate 401a. One end of the two ropes 402 is connected to the lower end surface of the square plate 401a, and the other end of the rope 402 is connected to the surface wall of the rotating cylinder 403. The upper end surface of the main positioning plate 501 is bolted with a compression plate 506, and the upper end surface of the compression plate 506 is fixed. There are two compression rods 506a arranged symmetrically in front and back. A U-shaped frame 502a is slidably provided on the upper end surface of each inclined splint 502 located in front and behind the compression plate 506. A linkage sleeve 505 is rotatably connected to each set of U-shaped frames 502a. A linkage rod 505a used in conjunction with the compression rod 506a is fixed on the upper end surface of the linkage sleeve 505. A shaft 507 is fixed to the concave position of the lower end of the main positioning plate 501 and the inclined splint 502. A roller 503 is sleeved on each shaft 507.

[0042] When using the above-mentioned structure, when steel pipes of different sizes pass through the lower position of the diagonal plate 201, the steel pipes of different sizes will move the diagonal plate 201 upward, and the diagonal plate 201 will move upward and control the calibration plate 206 to compress the calibration spring 207. After the calibration spring 207 pushes downward, the diagonal plate 201 always controls the retracting roller 205 to connect with the surface side of the steel pipe, ensuring that the steel pipe can always drive the retracting roller 205 to rotate, and the retracting roller 205 will retract the rope 402, and then the rope 402 drives the square plate 401a to move downward, thereby synchronously driving the sliding plate 401 to follow the movement, thereby realizing the use of a mechanical method to achieve autonomous compression of the steel pipe. When the main positioning plate 501 and the inclined splint 502 press the steel pipe, the rollers 503 below the main positioning plate 501 and the inclined splint 502 will be in contact with the surface of the steel pipe. Therefore, when the steel pipe moves, it will drive the rollers 503 to rotate on the shaft 507, which can avoid the situation where the steel pipe cannot move or rotate when the main positioning plate 501 and the inclined splint 502 press the steel pipe. At the same time, the linkage rod 505a moves downward, and the linkage rod 505a pushes the U-shaped frame 502a, so that the linkage sleeve 505 and the U-shaped frame 502a rotate relative to each other, and drive the U-shaped frame 502a to slide along the inclined splint 502, and push the inclined splint 502 to rotate tiltedly, thereby stably pressing the steel pipe.

[0043] Further, according to Figure 8 and Figure 9It can be seen that the upper and lower ends of the calibration spring 207 are fixed with abutment rings 207a respectively connected to the end faces of the calibration plate 206 and the mounting plate 301. The upper end face of the calibration plate 206 is fixed with a positioning rod 206b passing through the abutment ring 207a and the inside of the calibration spring 207. A positioning hole 301b is opened through the side wall of the mounting plate 301 corresponding to the positioning rod 206b. The upper end face of the positioning rod 206b is inserted into the positioning hole 301b. A circular plate 302 is provided at the position of the upper end face of the mounting plate 301 corresponding to the positioning hole 301b. The circular plate 302 is bolted to the upper end face of the positioning rod 206b by bolts. The side wall of the plate 301 is fixed with a limiting strip 301a that is bolted to the side wall of the adjustment plate 101. When the calibration plate 206 moves upward, the calibration plate 206 will drive the positioning rod 206b to slide inside the abutment ring 207a and the calibration spring 207, and the positioning rod 206b will slide in the positioning hole 301b. At the same time, the positioning rod 206b will drive the circular plate 302 to move upward. After the circular plate 302 limits the positioning rod 206b and the mounting plate 301 limits the circular plate 302, the calibration plate 206 is assembled and connected with the mounting plate 301, thereby assembling the diagonal plate 201 and the mounting plate 301.

[0044] Further, according to Figure 10 It can be seen that the front and rear side walls of the adjustment plate 101 are fixed with support plates 101b that are bolted to the external cutting equipment. The support plates 101b are installed on the external cutting equipment so that the diagonal plate 201 is located directly above the conveying structure of the cutting equipment, and the support plates 101b are located on both side edges of the conveying structure.

[0045] Need to explain, according to Figure 2 It can be seen that the rotating cylinder 403 is in the concave position on the surface side of the gathering roller 205, so the part connected with the steel pipe is the surface side position of the gathering roller 205 located in front and behind the rotating cylinder 403. Therefore, a wear-resistant sleeve is put on this position to increase the friction between the gathering roller 205 and the steel pipe. At the same time, when the main positioning plate 501 cannot continue to move up and down after connecting with the steel pipe, the gathering roller 205 is also unable to continue to rotate. The use of the wear-resistant sleeve can avoid direct friction between the gathering roller 205 and the steel pipe, and the wear-resistant sleeve needs to be replaced regularly. At the same time, the U-shaped frame 502a and the inclined clamping plate 502 are connected via a slide rail. Example 2

[0046] See also Figure 7 and Figure 10 On the basis of Example 1, this embodiment uses the reset spring 102 to achieve the function of self-reset of the sliding plate 401 and the diagonal plate 201.

[0047] Specifically, the left side wall of the adjustment plate 101 is provided with three groups of adjustment holes 101a arranged equidistantly from front to back. The upper and lower surfaces of the two groups of adjustment holes 101a located at the front and rear are connected to the end faces of the limit rods 101c arranged therein by bolts. The right side wall of the sliding plate 401 is fixed with two groups of sliding bars 401b respectively located in the adjustment holes 101a on both sides. The sliding bars 401b are sleeved on the limit rods 101c through the limit holes 401c opened through the side walls. The end faces of the sliding bars 401b passing through the adjustment holes 101a are all bolted to locking bars 404, and the locking bars 404 are connected to the side walls of the adjustment plate 101. The limit rods 101c located below the sliding bars 401b are sleeved with return springs 102. The calibration bar 206a fixed on the left side wall of the calibration plate 206 is in the adjustment hole 101a in the middle position of the adjustment plate 101, and the protrusions fixed on the end faces of the calibration bar 206a are connected to the left side wall of the adjustment plate 101.

[0048] By setting and using the above structure, the sliding bar 401b and the locking bar 404 are used in conjunction with each other to realize the sliding assembly between the sliding plate 401 and the adjusting plate 101. At the same time, when the sliding plate 401 moves downward, the sliding plate 401 will drive the sliding bar 401b to move downward in the adjusting port 101a and compress the return spring 102. Therefore, when the steel pipe is completely moved out from under the diagonal plate 201, the retraction roller 205 is no longer driven to rotate. As a result, the return spring 102 will push the sliding bar 401b to move upward and drive the sliding plate 401 to return to its original position. As a result, the sliding plate 401 is driven to move upward through the square plate 401a, thereby The rope 402 drives the retracting roller 205 to rotate in the opposite direction, controlling the retracting roller 205 to loosen. When the sliding plate 401 is reset to the initial position, the next steel pipe can be controlled to be set at the lower position of the diagonal plate 201, and the next steel pipe can be pressed again. Since the limit rod 101c is in the reset spring 102 and the limit hole 401c, the limit rod 101c limits the reset spring 102 to ensure that the reset spring 102 is compressed stably. At the same time, the detachable connection between the limit rod 101c and the adjustment plate 101, and the detachable connection between the locking bar 404 and the sliding bar 401b realize the disassembly and assembly between the sliding plate 401 and the adjustment plate 101. Example 3

[0049] See also Figure 2 、 Figure 7 and Figure 9 On the basis of Example 1, this embodiment can reduce the friction encountered by the rope 402 during movement by using the bending strip 203, the right-angle strip 202, the auxiliary strip 204 and the rope 402 in combination.

[0050] Specifically, the front and rear side walls of the diagonal plate 201 located on the right side of the furling roller 205 are both provided with a stretching hole 201a connected to the inner opening of the diagonal plate 201, and one end of the two ropes 402 respectively passes through the inner opening of the diagonal plate 201 from the hole position of the corresponding stretching hole 201a, and the front and rear side walls of the diagonal plate 201 located on the left side of the stretching hole 201a are bolted with a bending bar 203, and the ropes 402 pass around the outer side of the shaft tube of the bending bar 203, and the front and rear sides of the diagonal plate 201 located on the left side of the bending bar 203 are bolted with a right-angle bar 202, and the ropes 402 pass around the outer side of the shaft tube of the right-angle bar 202 from above, and the inner opening of the diagonal plate 201 located on the right side of the furling roller 205 is bolted with an auxiliary bar 204, and the two ropes 402 pass through the position between the two groups of auxiliary bars 204;

[0051] Through the arrangement and use of the above-mentioned structure, when the rope 402 is wound up by the retracting roller 205, the rope 402 moves along the shaft tube position on the bending bar 203, the right-angle bar 202 and the auxiliary bar 204, and at the same time the shaft tube can rotate on the bending bar 203, the straight bar and the auxiliary bar 204, thereby reducing the friction encountered by the rope 402 during movement. Example 4

[0052] See also Figure 4 、 Figure 5 and Figure 6 On the basis of Example 1, this embodiment realizes the rotation of the inclined clamping plate 502 along the side of the main positioning plate 501 through the rotational cooperation between the sleeve 501a and the I-beam 502b.

[0053] Specifically, sleeves 501a are fixed at the lower diagonal positions of the front and rear sides of the main positioning plate 501, and I-beams 502b used in conjunction with the sleeves 501a are fixed at the lower diagonal positions of the side walls of the inclined splint 502 close to the main positioning plate 501. A linkage frame 504 is provided above the main positioning plate 501, and both ends of the outermost part of the linkage frame 504 are provided with moving holes 504c arranged in an inverted convex shape, and both ends located in the middle of the linkage frame 504 are provided with compression holes 504a arranged in an inverted convex shape. The linkage frame 504 connects the adjacent compression holes 504a and the moving holes 504c through two curved holes 504b provided therein;

[0054] Through the setting and use of the above-mentioned structure, when the distance between the sliding plate 401 and the main positioning plate 501 is shortened, the compression rod 506a will slide in the compression hole 504a, thereby the compression rod 506a will compress the gas in the compression hole 504a, and connect the adjacent compression holes 504a and the movable hole 504c through the curved hole 504b. Therefore, the compressed gas pushes the linkage rod 505a to move in the movable hole 504c through the curved hole 504b, so that the linkage rod 505a will push the inclined splint 502 to rotate and move. Due to the rotational connection between the sleeve 501a and the I-beam 502b, the inclined splint 502 will drive the I-beam 502b to rotate with the sleeve 501a as the axis. Example 5

[0055] The present invention also provides a method for using a pipe pressing device for steel pipe cutting, which is operated according to the following steps:

[0056] S1: The entire device is installed directly above the conveying structure of the steel pipe cutting equipment. When the steel pipe is placed on the conveying structure, the conveying structure pushes the steel pipe to move, thereby moving the steel pipe to a position below the diagonal plate 201.

[0057] S2: When the steel pipe moves to the surface of the retracting roller 205, the friction between the retracting roller 205 and the steel pipe causes the movement of the steel pipe to drive the retracting roller 205 to rotate, and then the retracting roller 205 retracts the rope 402. Then the rope 402 pulls the square plate 401a downward, and controls the sliding plate 401 to move downward synchronously.

[0058] S3: After the previous step, the sliding plate 401 drives the main positioning plate 501 and the inclined clamping plate 502 to move downward, controlling the main positioning plate 501 to abut against the surface of the steel pipe. Therefore, as the retraction roller 205 continues to retract, the sliding plate 401 will continue to move downward synchronously.

[0059] S4: At this time, the main positioning plate 501 stops moving, thereby shortening the distance between the compression rod 506a and the sliding plate 401, and controlling the linkage rod 505a to move downward, and then the linkage rod 505a pushes the inclined clamping plate 502 to tilt and rotate, thereby controlling the two sets of inclined clamping plates 502 to clamp the steel pipe and press the steel pipe.
