Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of non-ferrous metal rod processing, in particular to a non-ferrous metal rod peeling traction device. BACKGROUND

[0002] Non-ferrous metals generally refer to all metals except iron and manganese. Such metals have characteristics such as luster, ductility, electrical conductivity, and heat conduction. They exist widely in the earth's crust and are mined and utilized in various forms. Non-ferrous metals are diverse, such as copper, lead, zinc, nickel, titanium, etc. Non-ferrous metals have a wide range of applications due to their unique physical and chemical properties. For example, copper has good electrical conductivity and thermal conductivity and is widely used in electrical wires, cables, pipes, and heat sinks. Titanium has low density, high strength, and corrosion resistance and is widely used in medical, chemical, aerospace, and automotive manufacturing industries.

[0003] Non-ferrous metals are produced and processed similarly to other metals, including smelting and mechanical processing steps. Rods are a widely used product structure form in mechanical processing. After processing, the surface of the rod may form an oxide layer due to external environmental influences, which may affect the subsequent application of the rod. Therefore, a rod peeling machine (centerless lathe) is commonly used in processing to remove the oxide layer (commonly known as peeling). The device structure is shown in the accompanying drawings, including a cutter mechanism that passes through the rod. The front and rear traction positions are arranged on both sides of the cutter mechanism shaft and drive the rod to move axially. The front and rear traction positions are symmetrically arranged above and below the shaft and have driving rollers that can abut the rod surface. The driving rollers on the front side drive the rod to move towards the cutter mechanism. After the rod is driven into the cutter mechanism, the cutter arranged in the cutter mechanism removes the oxide layer on the rod surface in the circumferential direction. At the same time, the driving rollers are driven to move the rod axially. When the rod end extends outside the cutter mechanism and enters the driving rollers in the rear traction position, the peeled rod is driven to continue moving forward from the front side to avoid the rod tail from being separated from the driving rollers on the front side without driving power, causing the rod and the cutter mechanism to be stationary relative to each other. Fig. 1-2 After the rod is peeled by the cutter mechanism, the surface is smooth and has high precision. When the driving rollers on the rear side drive the rod, the driving rollers must be pressed against the rod surface to overcome the force exerted by the cutter mechanism on the rod and ensure that the rod moves at a constant speed. The large pressure between the multiple driving rollers on the rear side and the rod surface can cause damage to the peeled rod surface, which cannot improve or ensure the quality of the rod surface after the oxide layer is removed.

[0022] In order to make those skilled in the art better understand the technical solutions of the present application, the technical solutions of the present application will be further described below in combination with the drawings and examples.

[0023] Referring to the drawings Figs. 1-10 The present application is a kind of non-ferrous metal bar peeling traction device, the peeling operation of bar includes the cutter mechanism 1 of bar, the traction device includes front side traction position and rear side traction position arranged in sequence on the two sides of the cutter mechanism 1 and drives the axial movement of bar, the front side traction position is symmetrical up and down and arranged with driving roller group 2 that can be in contact with the peripheral surface of bar. At present, the surface scale removal operation process of bar is: the driving roller group of front side traction position drives the bar to move towards the cutter mechanism direction, after the bar is driven into the cutter mechanism, the cutter arranged in the cutter mechanism removes the scale layer on the surface of bar along the circumference, at the same time, the driving of driving roller group makes the bar complete peeling operation along the axial direction.

[0024] And the present application is to solve the problem of surface damage caused by the rear side traction position to continue pulling the bar after the completion of the current bar peeling, such as Fig. 3As shown, this application provides a traction mechanism that moves along the axial direction of the bar at the rear traction position. This traction mechanism abuts against the bar and remains relatively stationary. That is, after the front end of the bar, after peeling, extends from the cutter mechanism 1, it enters the traction mechanism and is clamped by it. Since the traction mechanism can move along the axial direction of the bar, after clamping the front surface of the bar, the movement of the traction mechanism drives the bar to move continuously. The traction mechanism remains relatively stationary with respect to the bar, and only the part of the traction mechanism that contacts the bar achieves compression, while the majority of the bar is exposed. This effectively solves the problem of surface (pressure) damage to the bar after peeling caused by the current practice of still setting drive rollers at the rear traction position, thereby improving and ensuring the surface quality of the bar after peeling.

[0025] Specifically, such as Figs. 4-7 As shown, the traction mechanism includes a traction body 3 at the rear traction position through which a rod can pass, preferably a hollow structure with an inner cavity. Within the traction body 3, clamping blocks 4 (preferably with an arc-shaped contact surface) are arranged radially symmetrically with respect to the surface of the rod, and the clamping blocks 4 are preferably arranged symmetrically on the upper and lower sides of the rod. A drive cylinder 7 is provided on the traction body 3 to vertically raise and lower the clamping blocks 4 on the upper and lower sides. Fig. 5 As shown, when the peeled bar tip extends from the cutting mechanism 1 and enters the traction body 3, and further extends beyond the clamping block 4, it ensures that the surface of the clamping block 4 completely corresponds to and clamps the bar surface. A sensing sensor (not shown in the figure) can preferably be installed on the outside of the clamping block 4. Upon sensing the bar, it drives the drive cylinder to move, causing the upper and lower clamping blocks 4 to simultaneously clamp the bar surface and tighten the bar.

[0026] To achieve axial movement of the traction rod of traction body 3, such as Fig. 7 As shown, a drive guide rail 5 is also provided at the rear traction position to drive the traction body 3 to move axially. It is preferably a rack and pinion gear structure (not shown in the figure) that meshes with the traction body 3. The gear can be driven by a servo motor. After the clamping block 4 clamps the upper and lower sides of the bar, the servo motor drives the traction body 3 to pull the bar forward at the same peeling speed. When the tail end of the bar disengages from the drive roller group 2 at the front traction position, the bar continues to move forward under the traction of the traction body 3, causing the tail end of the bar to disengage from the cutter mechanism 1. Then, the clamping block 4 disengages from the bar surface and disassembles the bar. The traction body 3 then reverses and resets, waiting for the next bar clamping and traction operation. Compared to the currently provided rear drive roller group, the clamping block 4 can effectively reduce clamping damage to the bar surface, thereby improving the surface quality of the bar peeling operation.

[0027] To further reduce the clamping damage to the surface of the bar by the clamping block 4, preferably as follows: Fig. 8As shown in the drawings, the anti-skid block 6 is embedded on the clamping block 4 and abuts against the surface of the bar. The anti-skid block 6 is preferably a hard rubber block, which can effectively avoid hard damage to the surface of the bar after clamping contact and improve the anti-skid property of the surface of the bar. In order to avoid the problem of relative sliding and disengagement of the anti-skid block 6 from the clamping block 4 due to the reverse traction of the bar during the traction process, preferably, as shown in the drawings, Figs. 9-10 As shown in the drawings, the limiting protrusion 41 abutting against the side wall of the anti-skid block 6 is arranged on the clamping block 4 at the side opposite to the moving direction of the bar. The limiting protrusion 41 limits the rear end of the anti-skid block 6, thereby limiting the problem of relative movement and disengagement of the anti-skid block 6 from the clamping block 4 due to the reverse traction of the bar, and ensuring the stability of the bar traction.

[0028] Since the anti-skid block 6 made of rubber material will form a certain extrusion deformation after being pressed by the clamping block 4, the clamping force on the bar will be affected, therefore, in order to improve the clamping force on the bar, as shown in the drawings, Figs. 9-10 The anti-skid block 6 is arranged in a surface abutting manner with the clamping block 4 and is provided as a slope structure facing the reverse direction of the bar movement. The working principle is as shown in the drawings, Fig. 10 As shown in the drawings, the traction body 3 pulls the anti-skid block 6 and the bar to move forward in the direction of arrow a, and the reverse traction force of the bar and the friction force between the bar drive the anti-skid block 6 to move in the direction of arrow b towards the rear. During the movement of the anti-skid block 6 towards the rear, the top slope slides along the slope of the bottom of the clamping block 4 towards the rear, and the height of the bottom of the clamping block 4 from the surface of the bar gradually decreases towards the reverse direction, thereby causing the space height embedded with the anti-skid block 6 to gradually decrease, and the anti-skid block 6 is further pressed in the embedded space during the movement (as shown by arrow c in the drawings), thereby gradually increasing the pressing force on the anti-skid block 6 when the anti-skid block 6 is slid in the traction direction during the bar traction process, so as to ensure the stability during the bar traction process.

[0029] The principle of the present application is that the pulling body 3 and other components are arranged at the rear side of the tool mechanism 1 for peeling the bar. When the bar peeling operation is performed, the bar is threaded into the driving roller set at the front side of the tool mechanism 1 and is driven to move towards the tool mechanism 1. The bar is continuously driven so that the front end of the bar gradually enters the tool mechanism 1 for circumferential peeling processing. At the same time, the end of the bar is gradually extended to the outside of the tool mechanism 1 and is gradually threaded into the pulling body through the step-by-step driving of the driving roller set 2. When the front end of the bar extends to the outside of the clamping block 4, the driving cylinder is driven to act so that the anti-skid blocks 6 on the upper and lower clamping blocks 4 synchronously clamp the surface of the bar and clamp the bar. Then, the driving guide rail 5 drives the pulling body 3 to pull the bar at the peeling speed of the bar to continue moving forward. When the tail end of the bar is separated from the driving roller set 2 at the front side pulling position, the bar continues to move forward through the pulling of the pulling body 3. The tail end of the bar is separated from the tool mechanism 1. Then, the clamping block 4 is separated from the surface of the bar and the bar is disassembled. The pulling body 3 is reversely reset to wait for the clamping and pulling operation of the next bar. The operation can effectively reduce the clamping damage to the surface of the bar, thereby improving the surface quality of the bar peeling operation.

[0030] The basic principle, main features and advantages of the present application are shown and described above. There are various changes and improvements of the present application without departing from the spirit and scope of the present application. These changes and improvements all fall within the scope of the present application.
