Description

Technical Field

[0001] This invention relates to the field of feeding device technology, specifically to a multi-model steel pipe converging feed and propulsion device. Background Technology

[0002] With the rapid development of the pipe processing industry, the demand for steel pipes, as a widely used metal component, is constantly increasing. In the production and processing of steel pipes, pipe end closing is an important process in steel pipe forming. The closing feeding and pushing device directly determines the positioning accuracy of the steel pipe being fed into the closing machine. Therefore, a high-efficiency multi-model steel pipe closing feeding and pushing device is needed to complete the feeding and pushing operation of the steel pipe.

[0003] However, in the process of using the existing steel pipe closing feeding and propulsion device, the support and guiding structure is not easy to adapt to the conveying of steel pipes of various diameters. When switching between different types of steel pipes, the steel pipe support is prone to misalignment and pushing deviation, resulting in the steel pipe feeding positioning deviation and affecting the steel pipe closing processing quality. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-model steel pipe end-feeding and pushing device. By setting up a clamping part, it solves the problems of existing steel pipe end-feeding and pushing devices, where the support and guiding structure is not easy to adapt to the conveying of steel pipes of various diameters, and when switching between different models of steel pipes, the steel pipe support is prone to misalignment and pushing deviation, resulting in steel pipe feeding positioning deviation and affecting the quality of steel pipe end-feeding processing.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a multi-type steel pipe end-feeding and propulsion device, comprising a base plate and a pneumatic slide mounted on top of the base plate, and further comprising: a clamping part mounted on the pneumatic slide; several anti-friction parts arranged in a circular array above the pneumatic slide; several auxiliary support parts arranged in a circular array above the pneumatic slide; the clamping part includes a clamping assembly mounted above the pneumatic slide; a driving assembly mounted above the pneumatic slide; and the clamping assembly mounted on a support shell on the pneumatic slide, the inner wall of the support shell being rotatably connected. A rotating ring is provided, on which several arc-shaped grooves are formed. Each of the inner walls of these grooves is provided with a sliding column. The outer walls of each sliding column slide in contact with the inner walls of the grooves. Two sliding rods are fixedly connected to the outer walls of each sliding column. The outer walls of each sliding rod are slidably connected to a support shell. Several clamping blocks are fixedly connected to the sides of the sliding rods that are close to each other. The outer wall of the rotating ring is provided with a meshing element. Six clamping blocks are arranged in a circumferential array. Each clamping block has an anti-friction part and is connected to two sliding rods. The meshing element includes a toothed ring fixedly connected to the outer wall of the rotating ring; the toothed ring meshes with a gear. Further, the drive assembly includes a motor fixedly connected to the rear side of the support shell. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The front side of the rotating shaft extends rotatably into the support shell, and a gear is fixedly connected to the outer wall of the rotating shaft; the gear is located inside the support shell.

[0006] Furthermore, the anti-friction part includes an elastic component disposed on the corresponding clamping block; a rolling component mounted on the corresponding clamping block; the elastic component includes a rectangular groove formed on the corresponding clamping block, and a plurality of spring dampers are fixedly connected to the inner right wall of the rectangular groove; six spring dampers are provided and arranged in a linear array.

[0007] Furthermore, the rolling assembly includes a U-shaped slider slidably connected to the inner wall of the rectangular groove, and a plurality of rollers are slidably connected to the inner wall of the U-shaped slider; the right side of the U-shaped slider is fixedly connected to a plurality of spring dampers.

[0008] Furthermore, the auxiliary support includes a hinge rod hinged to the rear side of the support shell, an elastic support block fixedly connected to the hinge rod, and a fixing rod fixedly connected to the rear side of the clamping block. Contact elements are provided on the hinge rod and the fixing rod. There are six auxiliary support parts, and a fixing rod is fixedly connected to each clamping block. The contact element includes a sliding column two fixedly connected to the fixing rod. A straight sliding groove is opened on the hinge rod. The outer wall of the sliding column two slides in contact with the inner wall of the straight sliding groove.

[0009] The present invention has the following beneficial effects: (1) In this invention, by setting a clamping part, after the motor of the drive assembly is started, the motor output shaft drives the rotating shaft to rotate via a coupling. The rotating shaft passes into the support shell and drives the gear to rotate synchronously. The gear meshes with the gear ring on the outer wall of the rotating ring, thereby driving the rotating ring to make a circular rotation on the inner wall of the support shell. During the rotation of the rotating ring, the multiple arc-shaped grooves distributed on it follow the circular motion. The groove wall of the arc-shaped groove continuously applies a radial squeezing force to the sliding column 1 assembled inside. The sliding column 1 is guided and driven by the arc-shaped groove. Then, the sliding rods fixed on both sides of itself slide inward synchronously along the radial guide path of the support shell. The synchronous displacement of multiple sets of sliding rods drives the six clamping blocks to move together towards the center of the device in a circular array. The steel pipe is clamped by the synchronous radial feed of all clamping blocks. The automatic centering and clamping of steel pipes with various outer diameters is achieved by the synchronous circular motion, realizing the compatibility of steel pipes of various specifications, ensuring the coaxiality of the pushing process, avoiding the steel pipe from tilting, improving the stability of the closing and forming, and ensuring the quality of the steel pipe closing process. (2) By setting up an anti-friction part, the present invention moves closer to the outer wall of the steel pipe along with the clamping block. The spring damper applies an elastic pushing action to the U-shaped slider inside the rectangular groove, so that the roller contacts the outer wall of the steel pipe first. The rolling contact reduces the scratch damage to the outer wall of the steel pipe during the clamping process. At the same time, the roller allows the steel pipe to be adjusted slightly. When the clamping force continues to increase, the U-shaped slider compresses the spring damper and retracts into the rectangular groove, allowing the clamping block to directly bear the pressure to achieve rigid clamping. It takes into account both anti-scratch protection and clamping reliability, and is suitable for the buffer protection needs when clamping multiple types of steel pipes. (3) By setting up an auxiliary support part, the present invention moves in sync with the clamping action of the clamping block. The clamping block moves inward, driving the fixed rod and the second sliding column to move. The second sliding column slides along the straight sliding groove, causing the hinge rod to deflect and drive the elastic support block to abut against the outer wall of the rear section of the steel pipe. The six elastic support blocks form a circumferential auxiliary support, thereby lifting and limiting the rear end of the steel pipe away from the clamping position, alleviating the cantilever sagging moment generated during the feeding and pushing of the steel pipe, reducing the radial sway of the steel pipe, improving the overall rigidity of the long steel pipe during the feeding and pushing process, reducing the positional deviation during the closing process, further ensuring the coaxiality of the pushing process, and improving the forming quality of the closing process of multiple types of steel pipes.

Detailed Implementation

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figure 1 - Figure 8The present invention is a multi-type steel pipe closing feeding and propulsion device, including a base plate 111 and a pneumatic slide 112 installed on the top of the base plate 111, and further including: a clamping part 2, which is installed on the pneumatic slide 112; an anti-friction part 3, of which a plurality of anti-friction parts 3 are arranged in a circumferential array above the pneumatic slide 112; and an auxiliary support part 4, of which a plurality of auxiliary support parts 4 are arranged in a circumferential array above the pneumatic slide 112.

[0016] The clamping part 2 includes a clamping assembly 21, which is disposed above the pneumatic slide table 112; a driving assembly 22, which is also disposed above the pneumatic slide table 112; the clamping assembly 21 is mounted on a support shell 211 on the pneumatic slide table 112; a rotating ring 212 is rotatably connected to the inner wall of the support shell 211; the rotating ring 212 has several arc-shaped grooves 213; each of the arc-shaped grooves 213 has a sliding post 214 disposed on its inner wall; the outer walls of the sliding posts 214 slide in contact with the inner walls of the arc-shaped grooves 213; two sliding rods 215 are fixedly connected to the outer walls of each sliding post 214; the outer walls of the sliding rods 215 are slidably connected to the support shell 211; several clamping blocks 216 are fixedly connected to the side of the sliding rods 215 that are close to each other; the outer wall of the rotating ring 212 is provided with a meshing element; the clamping blocks 216 are provided with... Six clamping blocks 216 are arranged in a circular array. Each clamping block 216 is provided with an anti-friction part 3. Each clamping block 216 is connected to two sliding rods 215. The meshing part includes a toothed ring 217 fixedly connected to the outer wall of the rotating ring 212. The toothed ring 217 meshes with a gear 223. The drive assembly 22 includes a motor 221 fixedly connected to the rear side of the support shell 211. The output shaft of the motor 221 is fixedly connected to a rotating shaft 222 through a coupling. The front side of the rotating shaft 222 extends rotatably into the support shell 211. The outer wall of the rotating shaft 222 is fixedly connected to a gear 223. The gear 223 is located inside the support shell 211. By setting the clamping part 2, the automatic centering and clamping of steel pipes with various outer diameters is achieved by relying on the synchronous circumferential motion, realizing the compatibility of steel pipes of various specifications, ensuring the coaxiality during the pushing process, avoiding the steel pipe from tilting, improving the stability of the closing and forming, and ensuring the quality of the steel pipe closing process.

[0017] The anti-friction part 3 includes an elastic component 31, which is disposed on the corresponding clamping block 216; and a rolling component 32, which is mounted on the corresponding clamping block 216. The elastic component 31 includes a rectangular groove 311 formed on the corresponding clamping block 216, and a plurality of spring dampers 312 are fixedly connected to the inner wall of the right side of the rectangular groove 311. Six spring dampers 312 are arranged in a linear array. The rolling component 32 includes a U-shaped slider 321 slidably connected to the inner wall of the rectangular groove 311. Several rollers 322 are slidably connected to the inner wall; the right side of the U-shaped slider 321 is fixedly connected to several spring dampers 312. By setting the anti-friction part 3, the rollers 322 are made to contact the outer wall of the steel pipe first. The rolling contact reduces the scratch damage to the outer wall of the steel pipe during the clamping process. When the clamping force continues to increase, the U-shaped slider 321 compresses the spring damper 312 and retracts into the rectangular groove 311, allowing the clamping block 216 to directly bear the pressure to achieve rigid clamping. It takes into account both anti-scratching protection and clamping reliability, and is suitable for the buffer protection needs when clamping various types of steel pipes.

[0018] The auxiliary support part 4 includes a hinge rod 411 hinged to the rear side of the support shell 211. An elastic support block 412 is fixedly connected to the hinge rod 411. A fixing rod 413 is fixedly connected to the rear side of the clamping block 216. Contact elements are provided on the hinge rod 411 and the fixing rod 413. There are six auxiliary support parts 4. Each clamping block 216 is fixedly connected to a fixing rod 413. The contact element includes a sliding column 414 fixedly connected to the fixing rod 413. A straight sliding groove 415 is opened on the hinge rod 411. The outer wall of the sliding column 414 slides in contact with the inner wall of the straight sliding groove 415. By setting the auxiliary support part 4, the rear end of the steel pipe away from the clamping position is lifted and limited, which alleviates the cantilever sagging moment generated during the feeding and pushing of the steel pipe, reduces the radial sway of the steel pipe, improves the overall rigidity during the feeding and pushing of the long steel pipe, reduces the positional deviation during the closing process, further ensures the coaxiality of the pushing process, and improves the forming quality of the closing process of multiple types of steel pipes.

[0019] It should be noted that the control of motor 221 and pneumatic slide table 112 in this application can be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.

[0020] In use, the steel pipe to be processed is first inserted through the support shell 211, so that the steel pipe is centered between the six clamping blocks 216 arranged in a circular array. Then, the motor 221 of the drive assembly 22 is started. The output shaft of the motor 221 drives the rotating shaft 222 to rotate synchronously through the coupling. The rotating shaft 222 drives the gear 223 fixed on its outer wall to rotate. The gear 223 meshes with the toothed ring 217 on the outer wall of the rotating ring 212, driving the rotating ring 212 to rotate as a whole on the inner wall of the support shell 211. During the rotation of the rotating ring 212, the multiple arc-shaped grooves 213 inside it squeeze the sliding column 214 in the groove, pushing the sliding column 214 to move towards the center of the device. The sliding column 214 drives the sliding rods 215 fixed on both sides to slide radially inward along the support shell 211, thereby driving the six clamping blocks 216 to move closer to each other synchronously, realizing the centered clamping and positioning of the steel pipe. During the clamping process, the anti-friction part 3 on the clamping block 216 works synchronously. The spring damper 312 of the elastic component 31 can buffer the force through its own elastic expansion and contraction. In conjunction with the U-shaped slider 321 slidably connected in the rectangular groove 311, the position is adaptively fine-tuned so that the roller 322 on the inner wall of the U-shaped slider 321 always replaces the clamping block 216 in contact with the outer wall of the steel pipe. This not only avoids damage to the steel pipe from hard clamping, but also allows the roller 322 to assist in fine-tuning the installation position of the steel pipe through rolling. After the clamping block 216 clamps the steel pipe, it compresses the spring damper 312 and retracts into the rectangular groove 311 as a whole, without affecting the stability of the clamping part 2. At the same time, when the clamping block 216 moves inward, it drives the fixed rod 413 fixed on the rear side to move towards the center of the steel pipe. The sliding column 414 on the fixed rod 413 slides along the straight sliding groove 415 on the hinge rod 411, pulling the hinge rod 411 to rotate around the hinge point. This drives the elastic support block 412 fixed on the hinge rod 411 to move towards the outer wall of the rear side of the steel pipe. The six elastic support blocks 412 work together to complete the auxiliary support of the rear part of the steel pipe, improving the clamping stability of the steel pipe. After the steel pipe is clamped and supported, the pneumatic slide table 112 installed on the top of the base plate 111 can drive the overall clamping part 2, anti-friction part 3, auxiliary support part 4 and the clamped and fixed steel pipe to move as a whole, so as to complete the steel pipe closing and feeding operation.
