Description

Technical Field

[0001] This utility model relates to the field of beveling machines, and in particular to a beveling machine for seamless steel pipes. Background Technology

[0002] Seamless steel pipe is a long strip of steel with a hollow cross-section and no seams around its perimeter. It is named for the fact that its production process does not involve welding. A beveling machine is a specialized tool used to process a specific shape of bevel on the edges of metal pipes and plates. It is mainly used for pretreatment before welding, and its purpose is to improve the welding quality and ensure the weld strength by processing the bevel. Beveling seamless steel pipes during welding can improve the welding quality and ensure the connection strength.

[0003] In the process of realizing this application, the inventors discovered the following problems with the prior art: Existing seamless steel pipe beveling machines generally include structures such as cutting tools, seamless steel pipes, fixing mechanisms, and rotating mechanisms. When cutting the end face of the steel pipe, existing cutting tools mostly use a single tool to cut the inner and outer walls of the steel pipe, which is inefficient. At the same time, most existing cutting tools are fixed and can only cut steel pipes with uniform diameter or thickness, and cannot be adjusted according to the different thicknesses and diameters of the steel pipes, resulting in poor flexibility.

[0004] Therefore, those skilled in the art have provided a seamless steel pipe beveling machine to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a seamless steel pipe beveling machine. The machine can adapt to different steel pipe diameters through a roughness adjustment mechanism and to adapt to steel pipes of different thicknesses through a thickness adjustment mechanism.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seamless steel pipe beveling machine, comprising a roughness adjustment mechanism, a thickness adjustment mechanism, and a frame. The roughness adjustment mechanism includes a No. 1 motor, a No. 1 bidirectional screw, and a No. 1 locking block. Two No. 1 sliders are threadedly connected to the outer wall of the No. 1 bidirectional screw. A No. 1 frame is rotatably connected to the outer walls of both ends of the No. 1 bidirectional screw. Two No. 1 limiting rods are slidably connected to the inner wall of the end of the No. 1 slider near the No. 1 motor. The output end of the No. 1 motor is fixedly connected to the center of the end of the No. 1 frame near the No. 1 motor.

[0007] The thickness adjustment mechanism includes two No. 2 frames and two No. 2 locking blocks. The inner walls of the two No. 2 frames are rotatably connected to No. 2 bidirectional screws. The outer walls of the two No. 2 bidirectional screws are threadedly connected to two No. 2 sliders. A cutting tool is fixedly connected to the end of the multiple No. 2 sliders away from the No. 1 motor. The multiple No. 2 sliders are grouped in pairs. The inner walls of the two groups of No. 2 sliders near the No. 1 motor are slidably connected to two No. 2 limiting rods.

[0008] Furthermore, the multiple No. 2 limiting rods are arranged in pairs, forming two groups. The two ends of the No. 2 limiting rods in the two groups are respectively fixedly installed on the inner wall of the two No. 2 frames near the No. 1 motor.

[0009] Furthermore, a No. 2 bearing is fixedly installed at the middle of the outer wall of each of the two No. 2 bidirectional screws. The two No. 2 bearings are rotatably installed on the inner wall of the two No. 2 clamping blocks. The multiple No. 2 sliders are arranged in pairs, and the two sets of No. 2 sliders are respectively slidably installed on the inner wall of the two No. 2 frames.

[0010] Furthermore, the inner walls of the top and bottom of the two No. 2 frames are rotatably connected to the outer walls of the two No. 2 bidirectional screws. The multiple No. 2 limiting rods are divided into two groups of two. The middle of the outer walls of the two groups of No. 2 limiting rods is fixedly connected to the two No. 2 locking blocks near the No. 1 motor. The inner walls of the middle of the two No. 2 frames are fixedly connected to the outer walls of the two No. 2 locking blocks.

[0011] Furthermore, a servo motor is fixedly connected to the inner wall of the top of the first frame, and the output end of the servo motor is fixedly connected to the top of the first bidirectional screw. The outer walls of the two first sliders are slidably connected to the inner wall of the first frame.

[0012] Furthermore, a bearing is fixedly installed on the outer wall of the middle part of the first bidirectional screw, and the bearing is rotatably installed on the inner wall of the first clamping block.

[0013] Furthermore, the outer wall of the first card block is fixedly connected to the middle of the inner wall of the first frame, the outer walls of the two first limiting rods are fixedly connected to the inner wall of the first card block near the first motor, and the inner wall of the first frame near the first motor is fixedly connected to both ends of the two first limiting rods.

[0015] This utility model has the following beneficial effects:

[0016] 1. The present invention proposes a seamless steel pipe beveling machine. When the servo motor starts working, it causes the No. 1 bidirectional screw to rotate. The No. 1 bidirectional screw causes the two No. 1 sliders to move outward or inward along the two No. 1 limit rods and the inner wall of the No. 1 frame. The two No. 1 sliders drive the left-end cutter, the No. 2 frame and other structures to adjust according to the diameter of the steel pipe, so as to adapt to steel pipes of different diameters.

[0017] 2. The seamless steel pipe beveling machine proposed in this utility model has a No. 2 bidirectional screw rotating, which drives two No. 2 sliders to move up and down along two No. 2 limit rods and the inner wall of the No. 2 frame. The two No. 2 sliders further drive the left-end cutter to move up and down. The movement can be adjusted according to the thickness of the steel pipe, which can adapt to steel pipes of different thicknesses, thus increasing flexibility. At the same time, the cutting efficiency can be increased by setting two thickness adjustments. The cutter set on the inner and outer walls of the steel pipe can cut the inner and outer walls of the steel pipe at the same time, further improving efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-4This utility model provides an embodiment of a seamless steel pipe beveling machine, comprising a roughness adjustment mechanism 1, a thickness adjustment mechanism 2, and a frame 3. The roughness adjustment mechanism 1 includes a primary motor 103, a primary bidirectional screw 106, and a primary locking block 109. Two primary sliders 107 are threadedly connected to the outer wall of the primary bidirectional screw 106.

Two primary limiting rods 108 are slidably connected to the inner wall of the two primary sliders 107 near the end of the primary motor 103. The output end of the primary motor 103 is connected to the primary frame 109. 1. The thickness adjustment mechanism 2 is fixedly connected at the center of one end near the motor 103. It includes two second frames 201 and two second blocks 205. The inner walls of the two second frames 201 are rotatably connected to the second bidirectional screws 203. The outer walls of the two second bidirectional screws 203 are threadedly connected to two second sliders 204.

The inner walls of the two pairs of second sliders 204 near the motor 103 are slidably connected to two second limit rods 206.

[0026] Specifically, the first electric push rod 4 drives the pressure block to move down and fix the steel pipe between the pressure block and the frame 3. The servo motor 102 drives the first bidirectional screw 106 to rotate. The first bidirectional screw 106 causes the two first sliders 107 to move along the two first limit rods 108 and the inner wall of the first frame 101, which in turn moves the two thickness adjustment mechanisms 2 on the left end. The thickness is adjusted according to the diameter of the steel pipe. Then, the second bidirectional screw 203 is rotated. The second bidirectional screw 203 drives the two second sliders 204 on the outer wall to move up and down along the inner wall of the two second limit rods 206 and the inner wall of the second frame 201, and drives the cutter 202 to move up and down. The thickness can be adjusted according to the thickness of the steel pipe. Then, the first motor 103 drives all the structures on the left end to rotate, cutting the inner and outer walls of the right end of the steel pipe. The cutting progress of the steel pipe is then adjusted by the second electric push rod 104.

[0027] Reference Figures 1-4Multiple second-order limit rods 206 are arranged in pairs, forming two groups. The two groups of second-order limit rods 206 are fixed at both ends on the inner walls of the two second-order frames 201 near the first motor 103. Second-order bearings 207 are fixedly installed at the middle of the outer walls of the two second-order bidirectional screws 203. The two second-order bearings 207 are rotatably mounted on the inner walls of the two second-order locking blocks 205. Multiple second-order sliders 204 are arranged in pairs, with the two groups of second-order sliders 204 slidingly mounted within the two second-order frames 201. The inner walls of the top and bottom of the two No. 2 frames 201 are rotatably connected to the outer walls of the two No. 2 bidirectional screws 203. Multiple No. 2 limit rods 206 are arranged in pairs, forming two groups. The middle of the outer walls of both groups of No. 2 limit rods 206 is fixedly connected to the two No. 2 locking blocks 205 near the No. 1 motor 103. The inner walls of the two No. 2 frames 201 are fixedly connected to the outer walls of the two No. 2 locking blocks 205. A servo motor 102 is fixedly connected to the top inner wall of the No. 1 frame 101. The output end of 102 is fixedly connected to the top of the first bidirectional screw 106. The outer walls of the two first sliders 107 are slidably connected to the inner wall of the first frame 101. A first bearing 110 is fixedly installed on the outer wall of the first bidirectional screw 106 in the middle. The first bearing 110 is rotatably mounted on the inner wall of the first locking block 109. The outer wall of the first locking block 109 is fixedly connected to the inner wall of the first frame 101 in the middle. The outer walls of the two first limit rods 108 are connected to the first locking block 109 near the first motor 103. The inner wall is fixedly connected. The inner wall of frame 101 near motor 103 is fixedly connected to both ends of the two limit rods 108. A first electric push rod 4 is fixedly installed on the top of frame 3. A pressure block is fixedly installed at the output end of the first electric push rod 4. A fixing block 105 is fixedly installed on the outer wall of motor 103. A second electric push rod 104 is fixedly installed at the end of the fixing block 105 away from frame 101. The outer wall of the second electric push rod 104 is fixedly installed on the inner wall of one end of frame 3.

[0028] Specifically, the two second frames 201 provide fixation for the second limit rod 206, the second bidirectional screw 203 is set on the inner wall of the second locking block 205 through the second bearing 207, and will not move, only rotate. The second frame 201 provides fixation and support for the second locking block 205. The first frame 101 provides fixation and support for the servo motor 102. The servo motor 102 provides power for the rotation of the first bidirectional screw 106. The servo motor 102 has a self-locking structure. The first bidirectional screw 106 is set on the inner wall of the first locking block 109 through the first bearing 110, and will not move, only rotate. The frame 3 provides power for the second electric push rod 104.

[0029] Working principle: The steel pipe is placed between the pressure block and the two support blocks. The first electric push rod 4 is started to move the pressure block down to fix the steel pipe. Then the servo motor 102 is started to make the first bidirectional screw 106 rotate, which drives the two first sliders 107 to move outward or inward along the two first limit rods 108 and the inner wall of the first frame 101, and drives the two thickness adjustment mechanisms 2 on the left end to move outward or inward.

[0030] Secondly, after adjustment, rotate the second bidirectional screw 203 to drive the two second sliders 204 on the outer wall to move up and down along the inner walls of the two second limit rods 206 and the inner wall of the second frame 201. The up and down movement of the two second sliders 204 drives the cutter 202 on the left to move up and down. Adjust according to the thickness of the steel pipe. After adjusting the thickness, start the first motor 103. Its output end rotates to drive the roughness adjustment mechanism 1 and the thickness adjustment mechanism 2 to rotate, cutting the right end of the steel pipe. Then start the second electric push rod 104 to drive the whole mechanism to move towards the steel pipe and adjust the cutting progress.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
