Description

Technical Field

[0001] This utility model relates to the field of metal knurling technology, and in particular to a metal knurling device. Background Technology

[0002] Knurling is a key process in the surface finishing of metal products. By applying pressure to a metal workpiece at room temperature using one or more pairs of knurling wheels with patterns, the surface of the workpiece is plastically deformed to form regular patterns. Its core functions are anti-slip and decoration. It is widely used in tool manufacturing, instrumentation, automotive parts and other fields. Quickly adjusting and replacing knurling wheels is one of the means to improve the efficiency of knurling of metal products.

[0003] Place the metal product to be knurled in the device and clamp it in place. Control the height of the knurling wheel to fit the metal product. Replace the knurling wheel quickly according to the different knurling shapes. Finally, remove the cooling liquid and metal debris left on the surface of the metal product during the knurling process.

[0004] Existing metal knurling devices require tedious adjustments to the height of the knurling wheel to match the metal product, which affects the knurling efficiency. Furthermore, they lack the function of removing cooling liquid and generated metal debris during the knurling process, preventing operators from immediately detecting errors in the pattern. Therefore, a new metal knurling device is proposed. Utility Model Content

[0012] (III) Beneficial Effects This utility model provides a metal knurling device. It has the following advantages: 1. The adjustment mechanism allows for adjustment of the knurling wheel's height, adapting to knurling operations on metal products of different diameters. It also enables quick replacement of the knurling wheel according to knurling requirements. Pushing the adjustment plate towards the center of the support platform causes it to deform under pressure from the first spring, disengaging it from the toothed pressure plate. Moving the plate upwards to the appropriate position, multiple first springs apply a reverse thrust, locking the plate in the corresponding position on the toothed pressure plate, thus adjusting the knurling wheel's height. Loosening the nut allows the pressure block to slide upwards on the outside of the toothed pressure plate, enabling the knurling wheel to be removed and replaced. This design facilitates easy adjustment of the knurling wheel's height and allows for quick replacement, reducing adjustment time and improving the efficiency of knurling metal products.

If a problem occurs with the pattern, the machine can be stopped immediately for inspection, reducing waste generation. The operation of the fan is controlled to create negative pressure at the exhaust hood, sucking out the cooling liquid and metal debris together and sending them from the air duct to a suitable location for centralized treatment, thus achieving the function of removing cooling liquid and metal debris.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example 1 Reference Figures 1-4 This is the first embodiment of the present invention, which provides a metal knurling device, comprising: Support platform 1, with a multi-axis adjustment component installed on the top of support platform 1; Adjustment mechanism 2 is located on the top of the multi-axis adjustment component. Adjustment mechanism 2 includes multiple toothed pressure plates 201 evenly distributed on the top of the multi-axis adjustment component. Connecting plates 202 are installed on the top of two toothed pressure plates 201. Adjustment plates 203 are movably installed on the outer surface of the toothed pressure plates 201. A pressure block 210 is provided on the top of the adjustment plate 203. A knurled wheel 205 is provided on the side of the pressure block 210 opposite to the adjustment plate 203.

[0023] like Figure 2 and Figure 3 As shown, in this embodiment, the top of the adjusting plate 203 is provided with multiple arc grooves that are adapted to the toothed pressure plate 201. The adjusting plate 203 is movably engaged inside the toothed pressure plate 201 through the sliding groove. Multiple sliding rods 211 adapted to the pressure block 210 are evenly distributed on the top of the adjusting plate 203. The pressure block 210 is slidably connected to the outside of the sliding rods 211. The multiple sliding rods 211 are movably inserted into the connecting plate 202. The adjusting plate 203 is pushed towards the center of the top of the support platform 1, and the adjusting plate 203 is moved up or down. Finally, the adjusting plate 203 is pushed in the opposite direction so that it is engaged in the toothed pressure plate 201. The height of the adjusting plate 203 can be adjusted, thereby adjusting the height of the knurling wheel 205 to adapt to the knurling of metal products of different diameters.

[0024] like Figure 2 and Figure 3As shown, in this embodiment, a threaded rod 208 is installed at the top center of the adjusting plate 203, and a round hole adapted to the threaded rod 208 is opened at the top center of the pressure block 210. A nut 209 is threadedly connected to the outer surface of the threaded rod 208. The nut 209 is located at the top of the pressure block 210. By loosening the nut 209 on the outer surface of the threaded rod 208, the pressure block 210 can be lifted upward with the assistance of multiple sliding rods 211. The knurling wheel 205 can be replaced to adapt to the knurling operation of metal products with different requirements.

[0025] like Figure 4 As shown, in this embodiment, a first spring 207 and a damping rod 206 are installed on the inner surface of the sliding groove of the adjusting plate 203. The first spring 207 is located outside the damping rod 206. An I-beam block 204 is installed on one side of the damping rod 206. A T-shaped groove adapted to the I-beam block 204 is opened on one side of the toothed pressure plate 201. The I-beam block 204 is slidably connected inside the T-shaped groove. Under the action of multiple first springs 207, an outward pushing force is applied to the adjusting plate 203, so that the adjusting plate 203 is stably stuck in the toothed pressure plate 201. Under the action of the damping rod 206, it is prevented from popping out of the sliding groove of the adjusting plate 203 when the first spring 207 deforms.

[0026] Furthermore, the multi-axis adjustment component belongs to the conventional multi-axis operation mode well known to those skilled in the art. Its specific parameters can be selected according to actual needs. It can adjust the position of the knurling wheel 205. When it is necessary to adjust the height of the knurling wheel 205, the adjustment plate 203 is manually pushed towards the center of the top of the support platform 1, so that the adjustment plate 203 moves out of the toothed pressure plate 201. When the adjustment plate 203 moves, it applies pressure to several first springs 207 to cause deformation. Then the adjustment plate 203 moves upward. During the movement, the adjustment plate 203 drives several I-beams 204 to move in the corresponding toothed pressure plates 201. After the adjustment plate 203 moves to the appropriate position, under the action of several first springs 207... When the adjustment plate 203 is moved, a reverse thrust is applied to the adjustment plate 203, causing it to engage with the toothed pressure plate 201. As the adjustment plate 203 moves, it pushes the slide rod 211 upward, causing it to move within the connecting plate 202. This allows the knurled wheel 205 to be moved to the required height. When it is necessary to replace the knurled wheel 205 with a different pattern, the nut 209 is loosened from the threaded rod 208, and the pressure block 210 is moved upward to release the restriction on the knurled wheel 205. After removing the knurled wheel 205, a knurled wheel 205 with a different pattern is replaced. The knurled wheel 205 is placed on the opposite side of the pressure block 210 and the adjustment plate 203. The pressure block 210 is then pressed firmly against the top of the adjustment plate 203 by tightening the nut 209.

[0027] Example 2 Reference Figure 5This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The cleaning mechanism 3 is set on the top of the support platform 1. The cleaning mechanism 3 includes a hollow plate 301 installed on the top of the support platform 1. A T-shaped slider 302 is movably installed inside the hollow plate 301. A shim block 305 is provided on the top of the T-shaped slider 302. A mounting plate 307 is provided on the top of the shim block 305. An exhaust hood 309 is installed on the top of the mounting plate 307. A duct 310 is connected to one side of the exhaust hood 309.

[0028] like Figure 5 As shown, in this embodiment, a lead screw 304 is movably installed inside the hollow plate 301 via a bearing seat, and a T-shaped slider 302 is movably installed outside the lead screw 304 via a threaded sleeve. One end of the lead screw 304 extends to the outside of the hollow plate 301 and is equipped with a motor 303. When the lead screw 304 rotates, it can drive the T-shaped slider 302 to move, and then the shim block 305 moves accordingly, causing the exhaust hood 309 on the top of the shim block 305 to move along with the knurled wheel 205.

[0029] like Figure 5 As shown, in this embodiment, a telescopic cylinder 308 is installed on the top of the raised block 305, and a mounting plate 307 is installed on the output end of the telescopic cylinder 308. A fan 306 is installed on the top of the raised block 305, and the output end of the fan 306 is connected to the air duct 310 through a pipe. Under the action of the fan 306, negative pressure is applied to the exhaust hood 309, so that the exhaust hood 309 generates suction. The cooling liquid and metal debris entering from the exhaust hood 309 are sent out directly from the air duct 310 without passing through the fan 306.

[0030] Furthermore, the operation of motor 303 is controlled, and the output end of motor 303 drives lead screw 304 to move. Lead screw 304 drives T-shaped slider 302 to move the exhaust hood 309 to the horizontal position of knurling wheel 205. Then, the operation of telescopic cylinder 308 is controlled, and the output end of telescopic cylinder 308 pushes mounting plate 307, moving exhaust hood 309 to an angle above the metal product. Finally, the operation of fan 306 is controlled, and fan 306 generates negative pressure at one end of air duct 310 connected to exhaust hood 309 through pipe. With the assistance of exhaust hood 309, the cooling liquid and metal debris on the surface of the metal product are extracted together. During this process, lead screw 304 is controlled to rotate slowly so that exhaust hood 309 is always at the same level as knurling wheel 205.

[0031] Working principle: The device is connected to an external power supply and controller using a wiring harness. When the height of the knurling wheel 205 needs to be adjusted, the adjusting plate 203 is manually pushed towards the center of the top of the support platform 1, causing the adjusting plate 203 to move out of the toothed pressure plate 201. As the adjusting plate 203 moves, it applies pressure to several first springs 207, causing them to deform. Then, the adjusting plate 203 moves upward. During the movement, the adjusting plate 203 drives multiple I-beams 204 to move within their corresponding toothed pressure plates 201. The adjustment plate 203 moves to the correct position. After being positioned correctly, under the action of several first springs 207, a reverse thrust is applied to the adjusting plate 203, causing it to engage with the toothed pressure plate 201. As the adjusting plate 203 moves, it pushes the sliding rod 211 upwards, allowing it to move within the connecting plate 202, thus adjusting the knurling wheel 205 to the required height. When it is necessary to replace the knurling wheel 205 with one of different patterns, the nut 209 is loosened from the threaded rod 208, and the pressure block 210 is moved upwards to release the restriction on the knurling wheel 205, allowing the knurling wheel 205 to move freely. After removing 05, replace it with a knurling wheel 205 of a different pattern. Place the knurling wheel 205 on the opposite side of the pressure block 210 and the adjusting plate 203. Tighten the nut 209 to press the pressure block 210 onto the top of the adjusting plate 203. This allows for knurling operations on the desired metal products. During the knurling operation, control the operation of the motor 303. The output end of the motor 303 drives the lead screw 304, which in turn moves the T-shaped slider 302, moving the exhaust hood 309 to the horizontal position where the knurling wheel 205 is located. Then, control the telescopic cylinder 308 to operate. The output end of the telescopic cylinder 308 pushes the mounting plate 307, moving the exhaust hood 309 to an angle above the metal product. Finally, control the fan 306 to operate. The fan 306 generates negative pressure at one end of the air duct 310 connected to the exhaust hood 309 through the pipe. With the assistance of the exhaust hood 309, the cooling liquid and metal debris on the surface of the metal product are extracted together. During this process, control the lead screw 304 to rotate slowly so that the exhaust hood 309 is always at the same level as the knurling wheel 205.
