Description

Technical Field

[0002] As one of the most commonly used methods for processing pipes, wires, and bars, the drawing process can maximize the use of materials compared to turning, and it has a fast processing speed and a simple operation process. This process mainly uses the pulling force of the drawing machine to stretch the aluminum material to form a tubular product. The drawing process is a very important process in industrial production and has many application fields, such as construction, aerospace, automobile, rail transportation, packaging and other industries. However, the existing drawing devices mostly fix one end of the pipe directly by simple support. During the drawing process, this method is likely to cause the clamped end of the pipe to suddenly fall off, thereby greatly reducing the efficiency of drawing. In addition, in the process of drawing the pipe in the prior art, due to the excessive pulling force, the pipe surface cracks, peeling, center cracks and other problems occur. Once there are cracks and other problems on the pipe, the pipe is prone to breakage under strong drawing. Utility Model Content

During the drawing process, this method easily causes the clamped end of the pipe to suddenly fall off, thereby greatly reducing the drawing efficiency. In addition, in the process of drawing the pipe in the prior art, due to the excessive pulling force, the surface of the pipe is cracked, peeled, and the center crack is caused. Once there are cracks and other problems on the pipe, the pipe is prone to breakage under strong pulling.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tube drawing device that facilitates uniform drawing, comprising a uniform drawing structure, a clamping structure is symmetrically fixedly arranged on the uniform drawing structure, and a conveying structure is arranged in the center of the uniform drawing structure;

[0005] The conveying structure comprises a conveying box, a motor is fixedly arranged on one side of the outer side of the conveying box, a connecting shaft is arranged inside the conveying box, and the motor drives the connecting shaft to rotate;

[0006] A driving wheel is fixedly arranged on the connecting shaft, and the driving wheel is transmission-connected with a driven wheel fixedly arranged on the conveying roller through a belt, and both ends of the conveying roller are fixed above the conveying box.

[0007] By adopting the above technical solution, the connecting shaft is driven to rotate by a motor, so that the driving wheel fixed on the connecting shaft is transmitted through a belt to the driven wheel fixed on the conveying roller, so that the conveying roller rolls, thereby achieving the effect of conveying pipes.

[0008] Preferably, the uniform drawing structure includes a workbench, two grooves are respectively provided on the workbench, and two bases are symmetrically fixed on the workbench, and cylinders are fixedly arranged on the two bases. The cylinders are controlled by a control module, and both ends of the cylinders are fixedly connected by a first connecting rod passing through the clamping table.

[0009] Preferably, the two ends of the cylinder push the two clamping platforms to move relative to each other, and the two clamping platforms are connected to the connecting disk through a second connecting rod. One end of the second connecting rod is rotatably connected to the clamping platform, and the other end is rotatably connected to the connecting disk. The connecting disk is floated above the base, and a conveying box is arranged in the center of the connecting disk.

[0010] By adopting the above technical solution, when the control panel controls the two ends of the cylinder to push, the two clamping tables move relative to each other, and the second connecting rod rotates during the relative movement of the clamping tables. The second connecting rod drives the connecting plate to rotate during the rotation, so that the pipe to be drawn is evenly drawn.

[0011] Preferably, a support seat is fixedly provided below the clamping platform, and the support seat slides in the groove through a provided slider to assist in adjusting the position of the clamping structure.

[0012] By adopting the above technical solution, the support seat is provided to support the clamping table, and the support seat slides in the groove through the provided slider, thereby assisting in adjusting the position of the clamping structure.

[0013] Preferably, the clamping structure includes a clamping base, which is fixed on the clamping platform. A connecting seat is fixedly provided on the clamping base, and the connecting seat is rotatably connected to a connecting rod. The connecting rod is V-shaped, and one end of the V-shape is fixedly connected to the electric push rod.

[0014] Preferably, the other end of the V-shaped connecting rod is rotatably connected to a movable connecting rod, the movable connecting rod is rotatably connected to a right-angle connecting rod, and a clamping block is fixedly provided on the right-angle connecting rod.

[0015] By adopting the above technical solution, the electric push rod pushes one end of the connecting rod to move up and down, causing the other end of the connecting rod to rotate. During the rotation of the connecting rod, the movable connecting rod is driven to rotate, and the rotation of the movable connecting rod drives the right-angle connecting rod to rotate, thereby causing the clamping block fixed on the right-angle connecting rod to clamp the pipe.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the tube drawing device is convenient for uniform drawing.

[0017] (1) This case adopts a clamping structure to solve the problem that the existing drawing device fixes one end of the pipe directly by simple clamping. During the drawing process, this method easily causes the clamped end of the pipe to fall off suddenly, thereby greatly reducing the drawing efficiency. The electric push rod is set to push one end of the connecting rod to move up and down. During the up and down movement of one end of the connecting rod, the other end of the connecting rod rotates. During the rotation of the other end of the connecting rod, the movable connecting rod is driven to rotate. The rotation of the movable connecting rod drives the right-angle connecting rod to rotate, so that the clamping blocks fixed on the right-angle connecting rod are relatively close and far away, thereby clamping and fixing pipes of different diameters, thereby preventing the pipes from falling off;

[0018] (2) By setting up a uniform drawing structure, the problem of excessive drawing force during the drawing process of the pipe in the prior art, such as cracks on the pipe surface, peeling, and center cracks, can be solved. Once cracks and other problems exist on the pipe, the pipe is prone to breakage under strong drawing. The two ends of the cylinder are pushed to make the two clamping tables move relative to each other. During the relative movement of the clamping tables, the second connecting rod rotates. During the rotation of the second connecting rod, the connecting plate is driven to rotate. When the connecting plate rotates, the two clamping blocks are relatively separated, thereby drawing the pipe to be drawn. The clamping blocks are driven to move horizontally relative to each other by circular motion, so that the relative movement of the clamping blocks is more uniform and slow, so that the force on the pipe is more uniform during the drawing process, thereby reducing the breakage of the pipe.

[0026] See also Figure 1-5 , the utility model provides a technical solution: a tube drawing device that is convenient for uniform drawing;

[0027] like Figure 1 and Figure 2 As shown, it comprises a uniform drawing structure 1, a clamping structure 2 is symmetrically fixedly arranged on the uniform drawing structure 1, and a conveying structure 3 is arranged in the center of the uniform drawing structure 1;

[0028] The uniform drawing structure 1 includes a workbench 101, on which two grooves 102 are respectively provided, and the workbench 101 is symmetrically fixed with two bases 103, on which cylinders 104 are fixedly provided, and the cylinders 104 are controlled to work by a control module, and both ends of the cylinder 104 are fixedly connected by a first connecting rod 105 penetrating a clamping platform 106, and the two ends of the cylinder 104 push the two clamping platforms 106 to move relative to each other, and the two clamping platforms 106 are connected to a connecting disk 108 through a second connecting rod 107, one end of the second connecting rod 107 is rotatably connected to the clamping platform 106, and the other end is rotatably connected to the connecting disk 108, and the connecting disk 108 is floatingly arranged above the base 103, and a conveying box 301 is arranged in the center of the connecting disk 108, and a support seat 109 is fixedly arranged below the clamping platform 106, and the support seat 109 slides in the groove 102 through a set slider to assist in adjusting the position of the clamping structure 2.

[0029] In the above scheme, the control panel controls the push of the two ends of the cylinder 104, and the push of the two ends of the cylinder 104 causes the two clamping platforms 106 to move relative to each other. During the relative movement of the clamping platforms 106, the second connecting rod 107 is rotated, and during the rotation of the second connecting rod 107, the connecting plate 108 is driven to rotate, thereby pulling the pipe to be pulled, and the clamping block 207 is driven to move horizontally relative to each other through circular motion, so that the clamping block 207 moves more uniformly and slowly during the relative movement, so that the force on the pipe is more uniform during the pulling process, thereby reducing the breakage of the pipe fittings.

[0030] Furthermore, in the above scheme, when the two ends of the cylinder 104 push the clamping platform 106 to move relative to each other, the support seat 109 arranged below the clamping platform 106 slides in the groove 102 through the slider, and the support seat 109 supports the clamping platform 106 and assists in adjusting the position of the clamping structure 2.

[0031] like Figure 1 and Figure 3 As shown, the clamping structure 2 includes a clamping base 201, which is fixed on the clamping platform 106.

During the rotation of the other end of the connecting rod 203, the movable connecting rod 205 is driven to rotate. The rotation of the movable connecting rod 205 drives the right-angle connecting rod 206 to rotate, so that the clamping block 207 fixed on the right-angle connecting rod 206 clamps the pipe, thereby achieving the effect of effective clamping and preventing it from falling off.

During the rotation of the driving wheel 304, the belt 305 and the driven wheel 307 fixedly arranged on the conveying roller 306 are transmitted, so that the conveying roller 306 rolls. When one end of the pulled pipe is pulled, the electric push rod 204 stops working. At this time, the motor 302 drives the conveying structure 3 to work, and the other end of the pulled pipe is moved to the clamping base 201 for clamping, thereby achieving the effect of conveying the pipe and assisting the pulling.
