Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe processing, and particularly relates to a seamless steel pipe production and blanking device. Background Technique

[0002] Steel pipes are used for transporting fluids and powdery solids, exchanging heat energy, manufacturing mechanical parts and containers, and are also an economical steel. Steel pipes can be divided into two major categories according to the production method: seamless steel pipes and welded steel pipes. Among them, seamless steel pipes refer to those made by piercing a whole round steel, without welds on the surface. Compared with ordinary steel pipes, seamless steel pipes have stronger resistance, bending and tensile properties. In order to improve the production efficiency of seamless steel pipes, a blanking device is needed. However, the existing blanking devices still have the following deficiencies:

[0003] For example, the utility model with the application number 202121798536.4 discloses a blanking device for seamless steel pipe processing. In this utility model, by setting a fixed ring and a movable ring, and continuously rotating the displacement screw to drive the movable ring to continuously approach the fixed ring, the fixed ring and the movable ring complete the clamping work on the seamless steel pipe. After the seamless steel pipe completes the rust removal process, when the movable ring returns, under the action of the return spring in the kicking mechanism, the seamless steel pipe is kicked from the fixed ring to the blanking plate to complete automatic blanking. This not only improves the mechanization degree of the whole process but also liberates manpower. However, for comparative documents similar to the above application, when the existing blanking device is in use, since most blanking devices do not have a limiting structure when clamping seamless steel pipes, the seamless steel pipe is likely to be displaced due to excessive external force during cutting, resulting in the problems of reduced practicability and use efficiency of the blanking device.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a seamless steel pipe production and blanking device is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a seamless steel pipe production and blanking device to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A seamless steel pipe production and blanking device includes a workbench and a limiting component. Support column feet are installed at the bottom of the workbench. Limiting components are arranged on both sides of the upper end of the workbench. The limiting component includes a mounting block, a pneumatic rod, a clamping ring, a movable slider, a limiting through hole, a limiting through groove and a limiting rod. A pneumatic rod is installed inside the mounting block, and a clamping ring is arranged at the front end of the pneumatic rod. A movable slider is additionally arranged in the middle of the lower end of the clamping ring. A limiting through hole is opened inside the movable slider. Limiting through grooves are opened on both sides inside the workbench, and a limiting rod is installed inside the limiting through groove. A cutting component is arranged in the middle of the upper end of the workbench.

[0007] Further, the pneumatic rod and the mounting block are vertically distributed, and the pneumatic rod and the mounting block are fixedly connected by bolts.

[0008] Further, the outer dimensions of the movable slider are adapted to the inner dimensions of the limit through groove, and the movable slider is slidably connected to the workbench through the limit through groove.

[0009] Further, the inner dimensions of the limit through hole are adapted to the outer dimensions of the limit rod, and the limit rod is embeddedly connected to the movable slider through the limit through hole.

[0010] Further, the cutting assembly includes a support column rod, a limit sliding groove, a hydraulic cylinder and a mounting frame. Limit sliding grooves are provided on both sides inside the support column rod, a hydraulic cylinder is installed at the upper end inside the support column rod, and a mounting frame is provided at the front end of the hydraulic cylinder.

[0011] Further, the cutting assembly further includes a limit slider, a servo motor and a cutting tool. Limit sliders are provided on both sides outside the mounting frame. A servo motor is installed on the left side of the front end of the mounting frame, and a cutting tool is connected to the front end of the servo motor.

[0012] Further, the inner dimensions of the limit sliding groove are adapted to the outer dimensions of the limit slider, and the limit slider is slidably connected to the support column rod through the limit sliding groove.

[0013] Further, the cutting tool is embeddedly connected to the mounting frame, and the cutting tool is rotationally connected to the mounting frame through the servo motor.

[0014] The utility model provides a seamless steel pipe production and blanking device, which has the following beneficial effects:

[0015] 1. Through the setting of the limit component, when the seamless steel pipe production and blanking device is used, the pneumatic rod inside the mounting block operates to drive the clamping ring to move, so that the clamping ring clamps and limits the seamless steel pipe to be processed. At the same time, the outer dimensions of the movable slider provided in the middle of the lower end of the clamping ring match the inner dimensions of the limit through grooves provided on both sides inside the workbench, and the limit through holes provided inside the movable slider match the outer dimensions of the limit rods installed inside the limit through grooves. Therefore, when the movable slider moves inside the limit through groove, the cooperation of the limit through hole and the limit rod increases the stability of the movable slider during the movement process, thereby avoiding the position deviation of the seamless steel pipe after being clamped by the clamping ring and improving the overall practicability of the seamless steel pipe production and blanking device.

[0016] 2. Through the setting of the cutting component, when the seamless steel pipe production and blanking device is in use, the hydraulic cylinder at the upper end inside the support column rod operates to drive the mounting frame to move. At the same time, the internal dimensions of the limit sliders added on both sides outside the mounting frame match the internal dimensions of the limit sliding grooves opened on both sides inside the support column rod. Thus, the limit sliding grooves cooperate with the limit sliders to increase the stability during the movement of the mounting frame. The servo motor operates to drive the cutting knife to rotate, and the hydraulic cylinder drives the whole cutting knife to move downward to perform the blanking operation on the seamless steel pipe, thereby increasing the overall use efficiency of the seamless steel pipe production and blanking device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] As Figure 1 and Figure 2As shown in the figure, a seamless steel pipe production and blanking device includes a workbench 1 and a limiting component 3. Support column feet 2 are installed at the bottom of the workbench 1. Limiting components 3 are arranged on both sides of the upper end of the workbench 1. The limiting component 3 includes a mounting block 301, a pneumatic rod 302, a clamping ring 303, a movable slider 304, a limiting through hole 305, a limiting through groove 306 and a limiting rod 307.

A movable slider 304 is additionally provided in the middle of the lower end of the clamping ring 303. At the same time, a limiting through hole 305 is opened inside the movable slider 304. Limiting through grooves 306 are opened on both sides inside the workbench 1, and a limiting rod 307 is installed inside the limiting through groove 306. The pneumatic rod 302 and the mounting block 301 are vertically distributed, and the pneumatic rod 302 and the mounting block 301 are fixedly connected by bolts. The external dimension of the movable slider 304 is adapted to the internal dimension of the limiting through groove 306, and the movable slider 304 is slidably connected to the workbench 1 through the limiting through groove 306. The internal dimension of the limiting through hole 305 is adapted to the external dimension of the limiting rod 307, and the limiting rod 307 is embeddedly connected to the movable slider 304 through the limiting through hole 305. The mounting block 301 is fixedly installed on both sides of the upper end of the workbench 1 through fastening bolts, and the pneumatic rod 302 is fixedly installed inside the mounting block 301 by cooperating with the fastening bolts. The operation of the pneumatic rod 302 drives the clamping ring 303 to move in position, so that the clamping ring 303 clamps and limits the seamless steel pipe to be processed. At the same time, the external dimension of the movable slider 304 provided in the middle of the lower end of the clamping ring 303 matches the internal dimension of the limiting through grooves 306 opened on both sides inside the workbench 1. Therefore, the external dimension of the limiting rod 307 installed inside the limiting through hole 305 opened inside the movable slider 304 matches. Therefore, when the movable slider 304 moves inside the limiting through groove 306, the stability of the movable slider 304 during the movement is increased by cooperating the limiting through hole 305 with the limiting rod 307, so as to avoid the position deviation of the clamping ring 303 after clamping the seamless steel pipe, and improve the overall practicability of the seamless steel pipe production and blanking device.

[0023] As Figure 1 and Figure 3As shown in the figure, a cutting assembly 4 is provided in the middle of the upper end of the workbench 1. The cutting assembly 4 includes a support column rod 401, a limit sliding groove 402, a hydraulic cylinder 403 and a mounting frame 404. Limit sliding grooves 402 are provided on both sides inside the support column rod 401. A hydraulic cylinder 403 is installed at the upper end inside the support column rod 401, and a mounting frame 404 is provided at the front end of the hydraulic cylinder 403. The cutting assembly 4 further includes a limit slider 405, a servo motor 406 and a cutting tool 407. At the same time, limit sliders 405 are provided on both sides outside the mounting frame 404. A servo motor 406 is installed on the left side of the front end of the mounting frame 404, and a cutting tool 407 is connected to the front end of the servo motor 406. The internal dimension of the limit sliding groove 402 is adapted to the external dimension of the limit slider 405, and the limit slider 405 is slidably connected to the support column rod 401 through the limit sliding groove 402. The cutting tool 407 is embedded in the mounting frame 404, and the cutting tool 407 is rotationally connected to the mounting frame 404 through the servo motor 406. The support column rod 401 is fixedly installed at the rear side of the upper end of the workbench 1 through fastening bolts, and the hydraulic cylinder 403 is fixedly installed at the upper end inside the support column rod 401 in cooperation with the fastening bolts. The operation of the hydraulic cylinder 403 drives the mounting frame 404 to move in position. At the same time, the internal dimension of the limit sliders 405 added on both sides outside the mounting frame 404 matches the internal dimension of the limit sliding grooves 402 provided on both sides inside the support column rod 401, and the stability of the mounting frame 404 during movement is increased through the cooperation of the limit sliding groove 402 and the limit slider 405. The output shaft of the servo motor 406 provided at the front end of the mounting frame 404 is connected to the cutting tool 407 through a coupling. The operation of the servo motor 406 drives the cutting tool 407 to rotate, and the hydraulic cylinder 403 is used to drive the cutting tool 407 to move downward as a whole to perform the blanking operation on the seamless steel pipe, thereby increasing the overall use efficiency of the seamless steel pipe production blanking device.

[0024] In summary, for the seamless steel pipe production and blanking device, during use, first, the support column feet 2 installed at the bottom of the workbench 1 enhance the stability of the equipment during use. The pneumatic rod 302 inside the mounting block 301 operates to drive the clamping ring 303 to move, enabling the clamping ring 303 to clamp and limit the seamless steel pipe to be processed. At the same time, the outer dimension of the movable slider 304 provided in the middle of the lower end of the clamping ring 303 matches the inner dimension of the limit through groove 306 opened on both sides inside the workbench 1, and the limit through hole 305 opened inside the movable slider 304 matches the outer dimension of the limit rod 307 installed inside the limit through groove 306. Thus, when the movable slider 304 moves inside the limit through groove 306, the stability of the movable slider 304 during movement is enhanced through the cooperation of the limit through hole 305 and the limit rod 307, thereby preventing the position deviation of the clamping ring 303 after clamping the seamless steel pipe. Next, the hydraulic cylinder 403 operates to drive the mounting frame 404 to move. At the same time, the inner dimension of the limit sliders 405 added on both sides outside the mounting frame 404 matches the inner dimension of the limit sliding grooves 402 opened on both sides inside the support column rod 401. Thus, the stability of the mounting frame 404 during movement is enhanced through the cooperation of the limit sliding grooves 402 and the limit sliders 405. The output shaft of the servo motor 406 provided at the front end of the mounting frame 404 is connected to a cutting knife 407 through a coupling.
