[0002] Multi-station cold heading machine is an advanced metal forming equipment. It has multiple stations and can continuously complete multiple cold heading processes on the same machine. By multiple stampings on metal wires, it can quickly shape them into various precision parts. Multi-station cold heading machine can efficiently produce parts with complex shapes, such as bolts and nuts, and the products are high in precision and stable in quality. Multi-station cold heading machine has a high degree of automation, which reduces manual intervention and improves production efficiency. In the machinery manufacturing industry, multi-station cold heading machine plays an important role and meets the needs of large-scale and high-precision production.

[0019] The present invention also provides a method for using a multi-station cold heading machine, comprising the following specific steps:

[0020] Step 1: When debris appears in the multi-station cold heading machine due to damage to the punch, mold and production parts, the debris will be driven by the cold heading oil sprayed from the oil injection pipe to pass through the discharge port and the separation inlet in turn into the separation box. The debris and cold heading oil entering the separation box will pass through the inclined mesh plate and the filter to complete the secondary solid-liquid separation step. The small volume debris after solid-liquid separation will stay on the top of the filter, and the large volume debris and the produced parts will stay temporarily on the inclined mesh plate. When the ejector block moves downward under the drive of the cylinder and is placed flush with the inclined surface of the discharge inlet, the large volume debris and the parts at the production site will enter the discharge box, and finally be discharged from the discharge pipe during the upward reset movement of the ejector block. The filtered cold heading oil will be stored in the separation box. Because the separation box and the oil storage tank are connected through a connecting pipe, the cold heading oil after solid-liquid separation can be directly pumped out by the oil pump for reuse;

[0021] Step 2: When you need to clean small debris on the filter, first use the two force balls to rotate the two threaded rods counterclockwise. When the two threaded rods are completely out of the locking holes, the two force balls can be used to drive the switch plate to rotate. After the switch plate is rotated away from the top of the separation box, apply a vertical upward force to the U-shaped pull rod to drive the mounting ring out of the separation box. Then, turn the mounting ring upside down and knock on the filter to remove small debris on the filter. Then, repeat the above operation in reverse to reset the mounting ring, switch plate and two threaded rods.

[0022] Step 3: When the fuel injection pipe hinders the maintenance personnel from performing maintenance work on the multi-station cold heading machine, the auxiliary rod is used to drive the drive ring to rotate counterclockwise. The drive ring rotating counterclockwise in the drive hole will drive the annular pressure plate to move upward. When the annular rotating plate can rotate, the T-shaped force rod is used to drive the annular rotating plate, straight pipe and fuel injection pipe to rotate clockwise. When the fuel injection pipe is rotated to the top of the L-shaped protective plate, the fuel injection pipe will not hinder the maintenance work of the maintenance personnel.

[0023] Technical effects and advantages of the present invention:

[0024] (1) The present invention utilizes the arrangement of a separation mechanism and a recycling mechanism, and can quickly remove debris in the cold heading oil and reuse the cold heading oil through the cooperation among a separation box, a mounting ring, an inclined mesh plate, a filter screen, a discharge box, a top block, a cylinder, a discharge pipe, a connecting pipe, an oil storage tank and an oil pump, without the need for external equipment or human intervention, thereby reducing labor costs;

[0025] (2) The present invention utilizes the setting of the rotation assembly, and through the cooperation among the circular box, the driving hole, the straight pipe, the annular rotating plate, the annular pressing plate, the driving ring and the connecting hose, the fuel injection pipe can be rotated away from the maintenance area when the multi-station cold heading machine is maintained, and there is no need for maintenance personnel to disassemble and assemble the fuel injection pipe, thereby improving the convenience of maintenance work;

[0026] (3) The present invention utilizes the arrangement of an L-shaped protective plate, a baffle, a strip oil storage frame and a block. Through the cooperation between the L-shaped protective plate, the baffle, the strip oil storage frame and the block, the cold heading oil dripping from the nozzle of the fuel injection pipe can be collected while isolating and protecting the fuel injection pipe.

[0042] Working principle of the present invention:

[0043] When debris is generated in the multi-station cold heading machine due to damage to the punch, mold and production parts, the debris will be driven by the cold heading oil sprayed from the oil injection pipe 307 and pass through the discharge port 201 and the separation inlet 203 into the separation box 202 in turn. The debris and cold heading oil entering the separation box 202 will pass through the inclined mesh plate 211 and the filter screen 212 to complete the secondary solid-liquid separation step. The small-volume debris after solid-liquid separation will stay on the top of the filter screen 212, and the large-volume debris and the produced parts will stay on the inclined mesh plate 211. Temporarily retain, when the ejector block 216 moves downward under the drive of the cylinder 217 and is placed flush with the inclined surface of the discharge inlet 214, large-volume debris and parts from the production site will enter the discharge box 213, and finally be discharged from the discharge pipe 215 during the upward reset movement of the ejector block 216. The filtered cold heading oil will be stored in the separation box 202. Since the separation box 202 and the oil storage tank 303 are connected through the connecting pipe 302, the cold heading oil after solid-liquid separation can be directly pumped out by the oil pump 304 for reuse;

[0044] When it is necessary to clean small debris on the filter screen 212, firstly, the two threaded rods 219 are rotated counterclockwise by the two force-applying balls 221. When the two threaded rods 219 are completely out of the locking holes 220, the switch plate 206 can be driven to rotate by the two force-applying balls 221. After the switch plate 206 is rotated away from the top of the separation box 202, the mounting ring 210 is driven to be out of the separation box 202 by applying a vertical upward force to the U-shaped pull rod 209. Then, the mounting ring 210 is inverted and knocked against the filter screen 212 to remove the small debris on the filter screen 212. Then, the above operation is repeated in reverse to reset the mounting ring 210, the switch plate 206 and the two threaded rods 219.

[0045] When the fuel injection pipe 307 hinders the maintenance personnel from performing maintenance work on the multi-station cold heading machine, the auxiliary rod 30913 drives the drive ring 3098 to rotate counterclockwise, and the drive ring 3098 rotating counterclockwise in the drive hole 3092 will drive the annular pressure plate 3097 to move upward. When the annular rotating plate 3096 can rotate, the T-shaped force rod 30910 drives the annular rotating plate 3096, the straight pipe 3095 and the fuel injection pipe 307 to rotate clockwise. When the fuel injection pipe 307 rotates to the top of the L-shaped protective plate 4, the fuel injection pipe 307 will not hinder the maintenance work of the maintenance personnel.

10. A method for using a multi-station cold heading machine according to any one of claims 1 to 9, characterized in that: The specific steps include: Step 1: When debris is generated in the multi-station cold heading machine due to damage to the punch, mold and production parts, the debris will be driven by the cold heading oil sprayed from the oil spray pipe (307) and pass through the discharge port (201) and the separation inlet (203) to enter the separation box (202). The debris and cold heading oil entering the separation box (202) will pass through the inclined mesh plate (211) and the filter screen (212) to complete the secondary solid-liquid separation step. After the solid-liquid separation, the small-volume debris is located on the top of the filter screen (212) and stays. The large-volume debris and the produced parts are on the inclined mesh plate (211). Temporarily retained, when the ejector block (216) is driven by the cylinder (217) to move downward and be flush with the inclined surface of the ejector inlet (214), large-volume debris and parts from the production site will enter the ejector box (213) and eventually be discharged from the ejector pipe (215) during the upward reset movement of the ejector block (216). The filtered cold heading oil will be stored in the separation box (202). Since the separation box (202) and the oil storage tank (303) are connected through the connecting pipe (302), the cold heading oil after solid-liquid separation can be directly pumped out by the oil pump (304) for reuse; Step 2: When it is necessary to clean small debris on the filter (212), firstly, the two threaded rods (219) are rotated counterclockwise by the two force-applying balls (221). When the two threaded rods (219) are completely separated from the locking holes (220), the switch plate (206) can be driven to rotate by the two force-applying balls (221). After the switch plate (206) is rotated away from the top of the separation box (202), the U-shaped pull rod (209) is applied with a vertical upward force to drive the mounting ring (210) to separate from the separation box (202). Then, the mounting ring (210) is inverted and knocked against the filter (212) to remove the small debris on the filter (212). Then, the above operation is repeated in reverse to reset the mounting ring (210), the switch plate (206) and the two threaded rods (219). Step 3: When the oil injection pipe (307) hinders the maintenance personnel from performing maintenance work on the multi-station cold heading machine, the auxiliary rod (30913) drives the driving ring (3098) to rotate counterclockwise, and the driving ring (3098) rotating counterclockwise in the driving hole (3092) drives the annular pressure plate (3097) to move upward. When the annular rotating plate (3096) can rotate, the T-shaped force rod (30910) drives the annular rotating plate (3096), the straight pipe (3095) and the oil injection pipe (307) to rotate clockwise. When the oil injection pipe (307) rotates to the top of the L-shaped protective plate (4), the oil injection pipe (307) will not hinder the maintenance work of the maintenance personnel.
