Description

Technical Field

[0001] This utility model relates to the field of upsetting technology, specifically to an upsetting tube centering and clamping system. Background Technology

[0002] Upsetting machines are used to process pipe parts. By selecting different molds and cores, pipe materials can be deformed to achieve internal thickening, external thickening, and simultaneous internal and external thickening.

Limit plates are provided at both ends of the processing slide table. A bidirectional pushing mechanism is provided on one side of the processing slide table. Movable seats are provided at both ends of the bidirectional pushing mechanism. A rotating mechanism is provided on the movable seats.

[0004] After the tube blank is upset, it is usually necessary to test the product to meet the standard requirements. However, during the inspection process, due to the difference in diameter between the thickened sections at both ends of the thickened tube (the diameter is usually 20% to 50% larger than the middle straight tube section) and the straight tube section, problems such as centering deviation and unstable clamping are likely to occur when the tube is automatically transported to the inspection host. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose an upsetting pipe centering and clamping system to solve the technical problem in the prior art that the difference in diameter between the thickened sections at both ends of the pipe and the straight pipe section during the inspection process leads to centering deviation and unstable clamping of the pipe when it is automatically transported to the inspection host.

A first clamping assembly and a second clamping assembly are spaced apart on both sides of the detection host and both are connected to the bracket. The first and second clamping assemblies are configured to clamp and convey materials. The third and fourth clamping components are spaced apart on both sides of the two first clamping components and are both connected to the bracket. They are used to cooperate with the first and second clamping components to clamp and deliver materials so that the materials can continue to enter the detection host along the first axis.

[0007] In some embodiments, the first and second clamping components can both drive the material to translate relative to the first axis along a first direction, and the third and fourth clamping components can both drive the material to translate relative to the first axis along a second direction, wherein any two of the first direction, the second direction and the first axis are perpendicular to each other.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problem of centering deviation and unstable clamping of pipes during automated conveying to the testing host due to the diameter difference between the thickened sections at both ends of the thickened pipe and the straight pipe section, this invention provides a upset pipe centering and clamping system. This system, by setting a first clamping component 200a, a second clamping component 200b, a third clamping component 300a, and a fourth clamping component 300b on both sides of the testing host 400, can clamp and convey materials, ensuring that the materials always enter the testing host 400 along the first axis, effectively preventing axial deviation during automated conveying.

[0021] Please see Figures 1 to 6 , Figures 1 to 5This invention discloses a upset pipe centering and clamping system. The upset pipe centering and clamping system is configured to connect to a testing host 400, and the material can be conveyed along a first axis and enter the testing host 400. The system includes: a support 100, a first clamping component 200a, a second clamping component 200b, a third clamping component 300a, and a fourth clamping component 300b. The support 100 is connected to the testing host 400. The first clamping component 200a and the second clamping component 200b are spaced apart on both sides of the testing host 400 and connected to the support 100 and the material, respectively, for clamping the material. The third clamping component 300a and the fourth clamping component 300b are spaced apart on both sides of the two first clamping components 200a and connected to the support 100 and the material, respectively, for cooperating with the first clamping components 200a and the second clamping components 200b to clamp the material, so that the material can continue to enter the testing host 400 along the first axis.

[0022] In this application, compared with the prior art, by setting a first clamping component 200a, a second clamping component 200b, a third clamping component 300a and a fourth clamping component 300b on both sides of the detection host 400, the material can be clamped and conveyed, and the material can always enter the detection host 400 along the first axis. This effectively ensures that the material does not deviate from the axis during automated conveying, and can solve the technical problem in the prior art that the difference in diameter between the thickened section at both ends of the thick pipe and the straight pipe section during the inspection process can cause the pipe to easily deviate from the centering and be unstable when it is automatically conveyed to the detection host.

[0023] Furthermore, the testing host 400 here can be a tube upsetting machine, an ultrasonic testing host, a magnetic flux leakage testing host, etc. By setting up a tube upsetting centering and clamping system, the centering and coaxiality issues during the conveying process can be effectively guaranteed, thereby improving the accuracy of tube processing. The tube upsetting machine, ultrasonic testing host, and magnetic flux leakage testing host here are all conventional settings known to those skilled in the art, and will not be described in detail here.

[0024] Furthermore, due to the diameter difference between the thickened sections at both ends of the thickened pipe (whose diameter is usually 20% to 50% larger than the straight pipe section in the middle) and the straight pipe section, existing clamping devices have the following defects: insufficient centering accuracy. Traditional centering mechanisms use fixed spacing or manual adjustment, which cannot adapt to changes in the diameter of the upset pipe. When the thickened section at the pipe end passes through, center offset (the deviation often exceeds 1 mm) is prone to occur, affecting the accuracy of subsequent inspection. Poor clamping adaptability. When the thickened section transitions to the straight pipe section, the sudden change in clamping force can easily cause the pipe to shake or the surface to be indented. Slow response speed. Relying on manual judgment of the pipe position to adjust the clamping rollers, it is impossible to achieve real-time dynamic adaptation, resulting in low conveying efficiency. In order to address the above problems, this application combines the structural characteristics of the upset pipe to design a centering clamping system with accurate centering and stable transmission.

[0025] Furthermore, the upsetting device here is a conventional setup known to those skilled in the art. For reference, please refer to Chinese Utility Model Patent No. CN220805214U, entitled "A Double-Head Upsetting Tube Forming Equipment", which will not be elaborated here.

[0026] Furthermore, in this application, the support 100 is made of 150×150mm square tubing welded to form a rectangular frame structure. The frame is 4.8m long and 1.5m wide, and is used to support and install the detection host 400, the first clamping component 200a, the second clamping component 200b, the third clamping component 300a, and the fourth clamping component 300b. The mounting positions of each clamping mechanism above the frame structure are milled flat by a gantry milling machine to ensure installation accuracy, which will not be described in detail here.

[0027] In this embodiment, as Figures 1 to 3 As shown, the first clamping component 200a and the second clamping component 200b can both drive the material to translate relative to the first axis along the first direction, and the third clamping component 300a and the fourth clamping component 300b can both drive the material to translate relative to the first axis along the second direction. Any two of the first direction, the second direction and the first axis are set perpendicular to each other.

[0028] The first clamping component 200a and the second clamping component 200b are respectively disposed on both sides of the detection host 400 to realize the adjustment and centering of the material relative to the first axis in the left and right positions. The third clamping component 300a and the fourth clamping component 300b are respectively disposed on both sides of the detection host 400 to realize the adjustment and centering of the material relative to the first axis in the up and down positions.

[0029] Furthermore, by making fine adjustments to the material in four directions—up, down, left, and right—the centering and conveying of the material can be effectively ensured, reducing positional deviation and thus improving processing accuracy and product quality.

[0030] In one embodiment, the first clamping assembly 200a or the second clamping assembly 200b includes two first clamping members, which are spaced apart from each other on both sides of the first axis along a first direction and can move closer to or further away from each other to clamp materials.

[0031] By having two first clamping components respectively positioned on both sides of the material along the first direction, the material can be adjusted after being shifted to the left or right.

[0032] Furthermore, such as Figures 1 to 3As shown, the first clamping assembly 200a and the second clamping assembly are located on both sides of the detection host 400 and are arranged symmetrically along the axial direction relative to the detection host 400.

The first multiplier cylinder 214 is mounted on the first drive unit housing 201. A drive unit housing 201 is connected to a first driven roller assembly 202 via a first adjusting screw 206 and a first floating joint 207 on its side. A first transmission gear assembly 204 is fixed to the center of the first drive unit housing 201 and meshes with two sets of second transmission rack assemblies 205. Driven by a first multiplier cylinder 214, the first transmission gear assembly 204 and the second transmission rack assembly 205 can achieve the mutual opening and closing motion of the first driven roller assembly 202 and the first active roller assembly 203.

[0035] Furthermore, the first rear protective cover 209 is installed on the first drive unit housing 201 by four first spring-loaded buckles 210. It can be quickly removed during manual maintenance, providing complete protection and preventing injury from pinched hands.

[0037] By having two second clamping components positioned on either side of the material along the second direction, the material can be adjusted after its vertical position shifts.

[0038] Furthermore, such as Figure 1 , Figure 4 , Figure 5 As shown, the third clamping assembly 300a and the fourth clamping assembly are located on both sides of the detection host 400 and are arranged symmetrically along the axial direction relative to the detection host 400.

[0039] Furthermore, the second drive unit housing 301 is fixed above the bracket 1, using the second drive unit housing 301 as the overall installation reference. Its bottom is equipped with a counter-adjustment device, allowing adjustment of the center position along the front-back and up-down directions.

Driven by the second multiplier cylinder 312, the third transmission gear assembly 304 and the fourth transmission rack assembly 305 can realize the mutual opening and closing movement of the second driven clamping roller assembly 302 and the second active clamping roller assembly 303.

[0040] Furthermore, the second rear protective cover 310 and the second clamping roller mesh cover 309 are respectively installed on the second drive device housing 301 by four second spring-loaded buckles 311.

[0041] In one embodiment, such as Figure 6 As shown, the upsetting tube centering and clamping system also includes a detection component 500. The detection component 500 includes a first monitoring element 510 and a second monitoring element 520. The first monitoring element 510 and the second monitoring element 520 are respectively disposed on both sides of the third clamping component 300a and are both connected to the bracket 100. They are used to monitor the position of the material and control the two second clamping elements of the third clamping component 300a to move closer or further away from each other.

[0042] By setting the first monitoring element 510 and the second monitoring element 520, the positions of the beginning and end of the material can be monitored respectively, thereby controlling the opening or closing of the third clamping assembly 300a.

[0043] In one embodiment, such as Figure 6 As shown, the detection component 500 also includes a third monitoring element 530, which is disposed between the detection host 400 and the first clamping component 200a and cooperates with the second monitoring element 520.

[0045] In one embodiment, such as Figure 6 As shown, the detection component 500 also includes a fourth monitoring element 540 and a fifth monitoring element 550. The fourth monitoring element 540 and the fifth monitoring element 550 are respectively disposed on both sides of the second clamping component 200b and are both connected to the bracket 100. They are used to monitor the position of the material and control the two first clamping elements of the second clamping component 200b to move closer or further away from each other.

[0046] By setting the fourth monitoring element 540 and the fifth monitoring element 550 in conjunction, the positions of the beginning and end of the material can be monitored respectively, thereby controlling the opening or closing of the second clamping assembly 200b.

[0047] In one embodiment, such as Figure 6As shown, the detection component 500 also includes a sixth monitoring element 560, which is disposed on one side of the fourth clamping component 300b and cooperates with the fifth monitoring element 550.

[0050] In some embodiments, the upset tube is fed in by a front-end conveyor roller conveyor; when the head of the upset tube reaches the second monitoring element 520, the second clamping element of the third clamping assembly 300a closes; when the head of the upset tube reaches the third monitoring element 530, the first clamping element of the first clamping assembly 200a closes.

When the upset pipe tail reaches the first monitoring element 510, the second clamping element of the third clamping assembly 300a is activated. When the upset pipe tail reaches the second monitoring element 520, the first clamping element of the first clamping assembly 200a is activated. When the upset pipe tail reaches the fourth monitoring element 540, the first clamping element of the second clamping assembly 200b is activated.

[0051] In one embodiment, the upsetting tube centering and clamping system further includes a control component 600, which is electrically connected to the first clamping member, the second clamping member, the first monitoring member 510, the second monitoring member 520, the third monitoring member 530, the fourth monitoring member 540, the fifth monitoring member 550 and the sixth monitoring member 560.

[0052] The control component 600 enables automated and intelligent production. When the tube moves along the conveying path, the sensor can keenly detect the entry of the tube head and the exit of the tube tail, and quickly transmit the captured position signal to the electronic control unit of the equipment. After receiving the signal, the electronic control unit issues control commands in a timely manner according to the preset program and logic, and accurately triggers the opening and closing action of the centering drive unit, thereby ensuring that the centering drive unit and the conveying rhythm of the tube are precisely coordinated, and ensuring stable clamping and conveying of the tube.

[0053] Furthermore, the control component 600 here is a common and readily available electrical control cabinet on the market, such as a Siemens S7-1200 PLC, and the touch screen is a Siemens KTP1200; the industrial computer is equipped with an I5-6500 processor, 16G of memory, and a 120G solid-state drive to ensure smooth data processing, which will not be elaborated here.

[0054] In one embodiment, the upsetting tube centering and clamping system further includes an operating table 700, which is electrically connected to the control component 600.

[0055] The 700 control panel enables monitoring and management of the tube upsetting process, thereby improving production efficiency.

[0056] Furthermore, the operating console 700 here is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0057] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail below: The detection host 400 is connected to the support 100, and the material can be conveyed along the first axis and enter the detection host 400. The first clamping component 200a and the second clamping component 200b are spaced apart on both sides of the detection host 400 and are respectively connected to the support 100. Both the first clamping component 200a and the second clamping component 200b can be connected to the material for clamping the material. The third clamping component 300a and the fourth clamping component 300b are spaced apart on both sides of the two first clamping components 200a and are respectively connected to the support 100. Both the third clamping component 300a and the fourth clamping component 300b can be connected to the material for cooperating with the first clamping component 200a and the second clamping component 200b to clamp the material, so that the material can continue to enter the detection host 400 along the first axis. Compared with the existing technology, by setting the first clamping component 200a, the second clamping component 200b, the third clamping component 300a and the fourth clamping component 300b on both sides of the detection host 400, the material can be clamped and conveyed, and the material can always enter the detection host 400 along the first axis, effectively ensuring that the material does not deviate from the axis during automated conveying.

[0058] In the specific working process of this utility model, the upset tube is fed in by the front conveyor roller. When the head of the upset tube reaches the second monitoring element 520, the second clamping element of the third clamping assembly 300a closes; when the head of the upset tube reaches the third monitoring element 530, the first clamping element of the first clamping assembly 200a closes. When the upset pipe head reaches the fifth monitoring element 550, the first clamping element of the second clamping assembly 200b closes; when the upset pipe head reaches the sixth monitoring element 560, the second clamping element of the fourth clamping assembly 300b closes. When the upset pipe tail reaches the first monitoring element 510, the second clamping element of the third clamping assembly 300a is activated. When the upset pipe tail reaches the second monitoring element 520, the first clamping element of the first clamping assembly 200a is activated. When the upset pipe tail reaches the fourth monitoring element 540, the first clamping element of the second clamping assembly 200b is activated. When the upset pipe tail reaches the fifth monitoring element 550, the second clamping element of the fourth clamping assembly 300b is activated.

[0059] This application, through the aforementioned structure, can solve the technical problem in the prior art where the difference in diameter between the thickened sections at both ends of the thick pipe and the straight pipe section during the inspection process leads to centering deviation and unstable clamping of the pipeline when it is automatically transported to the inspection host.

[0060] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
