Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe production, in particular to a drawing device for steel pipe production. Background Art

[0002] Steel pipes are divided into seamless steel pipes and welded steel pipes. The production process of seamless steel pipes is to pierce solid tubes or ingots into hollow rough tubes, and then roll them into steel pipes of the required size. Different perforation and tube rolling methods are used, which constitute different methods for producing seamless steel pipes. The production process of welded steel pipes is to bend the tube billet (steel plate or strip) into a tube shape, and then weld the gap to form a steel pipe. Different forming and welding methods are used, which constitute different methods for producing welded steel pipes.

[0003] In the prior art, the effect of dragging and moving the drawn steel pipe is not very good, which means that after the steel pipe production is completed, it may be necessary to manually drag the steel pipe. Since the steel pipe is heavy, this increases the workload of the workers and wastes production capacity. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a drawing device for steel pipe production.

[0005] The utility model is implemented by the following technical scheme: a drawing device for steel pipe production, comprising a drawing mechanism, a forming mechanism and a moving mechanism, wherein the forming mechanism is located on the left side of the drawing mechanism, and the moving mechanism is located on the front side of the drawing mechanism;

[0006] The pulling mechanism includes a placement seat, the inner surface of the placement seat is fixedly connected to a fixed shaft 1, the surface of the fixed shaft 1 is rotatably connected to a roller 1, the left side of the placement seat is fixedly connected to a fixed ring, the surface of the fixed ring is threadedly connected to a hexagonal nut, the lower surface of the hexagonal nut is rotatably connected to a rotating shaft 1, the bottom of the rotating shaft 1 is fixedly connected to a clamping ring, and the bottom of the placement seat is slidably connected to a base.

[0007] As a further improvement of the above scheme, the number of the fixed shafts is set to four, and the four fixed shafts are located on the inner surface of the placement seat; the number of the hexagonal nuts is set to four, and the four hexagonal nuts are located on the inner surface of the fixing ring; and the clamping ring is located on the left side of the roller one.

[0008] Through the above technical solution, a fixing ring is provided to fix the hexagonal nut, so as to facilitate clamping of the formed steel pipe.

[0009] As a further improvement of the above scheme, the forming mechanism includes a drawing die cavity, the drawing die cavity is fixedly connected to the bottom of the base, the bottom of the base is fixedly connected to a fixed block, the inner surface of the fixed block is fixedly connected to a fixed shaft 2, and the surface of the fixed shaft 2 is rotatably connected to a roller 2.

[0010] As a further improvement of the above solution, the number of the fixed shafts 2 is eight, the eight fixed shafts 2 are located on the inner surface of the fixed block, and the roller 2 is located on the left side of the drawing die cavity.

[0011] Through the above technical solution, by setting a drawing die cavity, the unformed steel pipe can be formed to meet the production requirements.

[0012] As a further improvement of the above scheme, the moving mechanism includes a moving seat, which is fixedly connected to the upper surface of the base, a motor placement block is fixedly connected to the right side of the moving seat, a motor is fixedly connected to the upper surface of the motor placement block, a threaded rod is fixedly connected to the output end of the motor, a threaded connecting rod is threadedly connected to the surface of the threaded rod, an optical axis is fixedly connected to the inner surface of the moving seat, and an optical axis connecting rod is slidably connected to the surface of the optical axis.

[0013] As a further improvement of the above scheme, there are two movable seats, which are located on the upper surface of the base, one end of the threaded connecting rod is fixedly connected to the front side of the placement seat, and one end of the optical axis connecting rod is fixedly connected to the back side of the placement seat.

[0014] Through the above technical solution, the placement seat and the mechanism above it are moved left and right through the threaded connecting rod and the optical axis connecting rod, so as to meet the transportation work after the steel pipe is drawn.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model sets a fixing block, and the steel pipe passes through the hole opened in the fixing block and contacts with the surface of the second roller. At the same time, the smooth surface of the second roller is used to make the movement of the steel pipe more labor-saving. The steel pipe continues to move forward and moves to the inside of the drawing die cavity to further shape the steel pipe. After completion, the motor is started to rotate the threaded rod, thereby driving the threaded connecting rod to rotate. Since the threaded connecting rod and the bottom of the optical axis connecting rod are fixedly connected to the two sides of the placement seat, the optical axis connecting rod will slide along the surface of the optical axis to drive the movement of the placement seat.

[0017] The utility model sets a hexagonal nut. After it is moved to a suitable position, the hexagonal nut can be rotated to drive the clamping ring below to move. At this time, due to the rotating shaft, the clamping ring will not rotate, but will only move according to the position of the hexagonal nut. At the same time, since there are four hexagonal nuts, it is also guaranteed that the steel pipe is connected more tightly. The steel pipe can pass through the placement seat. A roller is set on the inner surface of the placement seat, which can also help to move the steel pipe more easily. After clamping the steel pipe, the motor can be started to move the placement seat to the right to drag the steel pipe, and at the same time, the steel pipe that has not passed through the drawing die cavity passes through its interior to complete the production.

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0029] The pulling mechanism 1 includes a placement seat 105, the inner surface of the placement seat 105 is fixedly connected to a fixed shaft 107, the surface of the fixed shaft 107 is rotatably connected to a roller 106, the left side of the placement seat 105 is fixedly connected to a fixed ring 102, the surface of the fixed ring 102 is threadedly connected to a hexagonal nut 101, the lower surface of the hexagonal nut 101 is rotatably connected to a rotating shaft 104, the bottom of the rotating shaft 104 is fixedly connected to a clamping ring 103, and the bottom of the placement seat 105 is slidably connected to a base 108.

[0030] There are four fixed shafts 107 , which are located on the inner surface of the placement seat 105 ; there are four hexagonal nuts 101 , which are located on the inner surface of the fixing ring 102 ; and the clamping ring 103 is located on the left side of the roller 106 .

[0031] The forming mechanism 2 includes a drawing die cavity 204, which is fixedly connected to the bottom of the base 108. A fixed block 201 is fixedly connected to the bottom of the base 108. A fixed shaft 202 is fixedly connected to the inner surface of the fixed block 201. A roller 203 is rotatably connected to the surface of the fixed shaft 202.

[0032] There are eight fixed shafts 202 , which are located on the inner surface of the fixed block 201 , and the roller 203 is located on the left side of the drawing die cavity 204 .

[0033] The moving mechanism 3 includes a moving seat 301, which is fixedly connected to the upper surface of the base 108. A motor placement block 307 is fixedly connected to the right side of the moving seat 301, a motor 302 is fixedly connected to the upper surface of the motor placement block 307, a threaded rod 303 is fixedly connected to the output end of the motor 302, a threaded connecting rod 304 is threadedly connected to the surface of the threaded rod 303, an optical axis 305 is fixedly connected to the inner surface of the moving seat 301, and an optical axis connecting rod 306 is slidably connected to the surface of the optical axis 305.

[0035] The implementation principle of a drawing device for steel pipe production in the embodiment of the present application is as follows: the steel pipe passes through the hole opened in the fixed block 201 and contacts the surface of the second roller 203.

After clamping the steel pipe, the motor can be started to move the placement seat 105 to the right to drag the steel pipe, and at the same time, the steel pipe that has not passed through the drawing die cavity 204 passes through its interior to complete the production.
