Description

Technical Field

[0001] This utility model relates to the field of dry wire drawing technology, specifically to a powder clamp for dry wire drawing. Background Technology

[0002] Dry wire drawing is an important metal processing process. Dry drawing is mainly carried out by a wire drawing machine. After the wire blank is surface prepared, the ends are rolled thin by a tipping mill. Then, the wire is plastically deformed by the drawing force of the wire drawing machine and the pressure of the die wall under the action of the die to obtain the desired shape of the wire.

[0003] During the wire drawing process, the drawing equipment is equipped with a powder box containing lubricating powder. After the wire passes through the powder box, its surface is coated with lubricating powder for subsequent drawing. To increase the powder carrying capacity of the wire, powder clamps are used to hold the wire in the powder box. The wire passes through the spools between the powder clamps, causing the spools to rotate and agitate the lubricating powder, thus ensuring that the lubricant adheres evenly to the surface of the wire. However, most existing powder clamps hold the wire from both horizontal sides, making it easy for the wire to slip off between the spools. Utility Model Content

[0026] Please see Figure 1This utility model provides a powder clamp for dry wire drawing, which includes a fixing part 100, a first connecting part 200, and a second connecting part 300. The fixing part 100 is arranged horizontally and is used for fixed connection with the powder box. One end of the first connecting part 200 is fixedly connected to the fixing part 100, and the other end of the first connecting part 200 extends vertically. A first wire pulley 210 is rotatably mounted on the end of the first connecting part 200 away from the fixing part 100. The second connecting part 300 is slidably disposed on the first connecting part 200 in a vertical direction. A second wire pulley 310 that cooperates with the first wire pulley 210 is rotatably mounted on the second connecting part 300. The first wire pulley 210 and the second wire pulley 310 are arranged vertically and together form a channel for the steel wire to pass through. When the steel wire slides and moves in the channel, the first wire pulley 210 and the second wire pulley 310 simultaneously limit the movement of the steel wire. The powder clamp for dry wire drawing of this application limits the wire by means of a first wire pulley 210 and a second wire pulley 310 arranged in the vertical direction. The lower first wire pulley 210 can provide more effective support for the wire, which can reduce the wire slippage caused by the fluctuation of the wire under the action of gravity and greatly improve work efficiency.

[0027] Please see Figures 1 to 3 In one embodiment, the fixing part 100 includes a first crossbeam 110 and a first fixing plate 120. One end of the first fixing plate 120 is fixedly connected to one end of the first crossbeam 110, and the other end of the first fixing plate 120 is fixedly connected to the first connecting part 200. In this embodiment, a screw 121 is fixedly disposed on the side of the first fixing plate 120 facing the first connecting part 200. A sliding groove 220 adapted to the screw 121 is provided on the first connecting part 200. The screw 121 passes through the sliding groove 220 and is fixedly connected to the first fixing plate 120 and the first connecting part 200 by a nut 1211. The screw 121 slides vertically within the sliding groove 220. By adjusting the position of the screw 121 in the sliding groove 220, the height of the first connecting part 200 can be adjusted, thereby adjusting the height of the first thread pulley 210 and the second thread pulley 310 to meet the usage requirements of different scenarios. Specifically, when adjusting the height of the first connecting part 200, first loosen the nut 1211, then slide the screw 121 vertically in the slide groove 220 to the appropriate position, and then tighten the nut 1211. There are no restrictions on the method of fixing the screw 121 to the first connecting part 200; for example, the screw 121 can be welded to the first connecting part 200.

[0028] Please see Figure 1 and Figure 2In one embodiment, the fixing part 100 further includes a second fixing plate 130, a third fixing plate 140, and a fixing bolt 150. The second fixing plate 130 is disposed opposite to the first fixing plate 120 at the other end of the first crossbeam 110. The third fixing plate 140 is disposed between the first fixing plate 120 and the second fixing plate 130. The second fixing plate 130 is provided with a threaded groove that matches the fixing bolt 150. The fixing bolt 150 passes through the threaded groove and is fixedly connected to the second fixing plate 130. In use, the side wall of the powder box is placed between the second fixing plate 130 and the third fixing plate 140, and the fixing bolt 150 is rotated so that one side of the side wall of the powder box abuts against the fixing bolt 150, and the other side of the side wall of the powder box abuts against the third fixing plate 140, so as to fix the powder clip on the powder box. There are no restrictions on the connection method between the second fixing plate 130 and the first crossbeam 110, or the connection method between the third fixing plate 140 and the first crossbeam 110. For example, the second fixing plate 130 and the third fixing plate 140 can be welded to the first crossbeam 110 respectively.

One end of the elastic member 250 abuts against the top wall of the groove 230, and the other end of the elastic member 250 abuts against the second crossbeam 320. In use, the elastic member 250 pushes the second crossbeam 320 downward, which in turn drives the connecting plate 330 downward. The downward movement of the connecting plate 330 drives the second wire wheel 310 downward, and the second wire wheel 310 presses against the first wire wheel 210, thereby clamping the steel wire. Here, the elastic member 250 can be any material that deforms under external force and can return to its original shape after the external force is removed. For example, the elastic member 250 is a compression spring. The installation method of the support rod 240 is not limited here; for example, the support rod 240 can be fixed by bolts.

[0031] Please see Figure 1 , Figure 3 and Figure 4In one embodiment, a sliding sleeve 241 is provided between the support rod 240 and the first through hole 321. The sliding sleeve 241 enables the second crossbeam 320 to slide more smoothly on the support rod 240, reducing vibration or jamming caused by friction and improving the stability and accuracy of sliding. In this embodiment, the sliding sleeve 241 and the first through hole 321 are interference-fitted. In use, the elastic element 250 pushes the sliding sleeve 241 downward, the sliding sleeve 241 drives the second crossbeam 320 downward, and the second connecting part 300 drives the second wire pulley 310 downward, so that the second wire pulley 310 and the first wire pulley 210 cooperate to clamp the steel wire.

[0032] Please see Figure 1 and Figure 3 In one embodiment, a bearing (not shown in the figure) is fixedly mounted on the first connecting portion 200, and a shaft 260 is fixedly mounted on the bearing. The end of the shaft 260 facing away from the bearing is fixedly connected to the first reel 210. In this embodiment, a sealing box 270 for placing the bearing is provided on the first connecting portion 200. The sealing box 270 includes a cover plate 271 and a side wall 272. One end of the side wall 272 is fixedly connected to the first connecting portion 200, and the cover plate 271 covers the other end of the side wall 272 and is fixedly connected to the side wall 272. A second through hole 2711 is provided on the cover plate 271 for the shaft 260 to pass through. Placing the bearing inside the sealing box 270 can prevent lubricating powder from entering and improve the service life of the powder clamp. The sealing box 270 can be of any shape, such as cylindrical. The connection method of the cover plate 271 and the side wall 272 is not limited here. For example, the cover plate 271 and the side wall 272 can be fixedly connected by bolts.

[0033] This utility model discloses a powder clamp for dry wire drawing. A first connecting part is fixedly mounted on a fixed part, and a second connecting part is slidably mounted on the first connecting part in a vertical direction. A first wire pulley is rotatably mounted on the first connecting part, and a second wire pulley, which cooperates with the first wire pulley, is rotatably mounted on the second connecting part.
