Description

Technical Field

[0001] This invention relates to the field of cold heading machine technology, and in particular to a multi-station cold heading machine and its usage method. Background Technology

[0002] Multi-station cold heading machines are advanced metal forming equipment. With multiple stations, they can continuously complete multiple cold heading processes on the same machine. Through repeated stamping of metal wire, they quickly shape it into various precision parts. Multi-station cold heading machines can efficiently produce complex-shaped parts, such as bolts and nuts, with high precision and stable quality. Their high degree of automation reduces manual intervention and improves production efficiency. In the machinery manufacturing industry, multi-station cold heading machines play a vital role in meeting the demands of large-scale, high-precision production.

[0003] During the production of parts using a multi-station cold heading machine, damage to punches, dies, and production parts can occur. This damage generates debris, which inevitably enters the cold heading oil, causing oil contamination. Currently, multi-station cold heading machines do not have the function of completely removing debris from the cold heading oil. Therefore, it is necessary to use a slag removal device to process the oil before it can be reused. This process is cumbersome and requires manual intervention, increasing labor costs.

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

[0020] Step 1: When debris caused by damage to punches, dies, and production parts appears in the multi-station cold heading machine, the debris will be driven by the cold heading forming oil sprayed from the oil spray pipe to pass through the discharge port and separation inlet into the separation box. The debris and cold heading forming oil in the separation box will complete a secondary solid-liquid separation step through the inclined screen and filter screen. Small-volume debris after solid-liquid separation will stay at the top of the filter screen, while large-volume debris and the produced parts will be temporarily retained on the inclined screen. When the top block moves downward under the drive of the cylinder and is aligned with the inclined surface of the discharge inlet, the large-volume debris and the produced parts will enter the discharge box and finally be discharged from the discharge pipe during the upward reset movement of the top block. The filtered cold heading forming oil will be stored in the separation box. Since the separation box and the oil storage tank are connected by a connecting pipe, the cold heading forming oil after solid-liquid separation can be directly pumped out by the oil pump for reuse.

[0021] Step 2: When small debris needs to be cleaned from the filter screen, first rotate the two threaded rods counterclockwise using the two force balls. Once both threaded rods are completely disengaged from the locking holes, the two force balls can be used to rotate the switch plate. After the switch plate rotates away from the top of the separation box, apply a vertical upward force to the U-shaped pull rod to disengage the mounting ring from the separation box. Then, invert the mounting ring and tap the filter screen to remove the small debris. Repeat the above steps in reverse to reset the mounting ring, switch plate, and two threaded rods.

[0022] Step 3: When the fuel injection pipe obstructs the maintenance personnel from performing maintenance work on the multi-station cold heading machine, the auxiliary rod drives the drive ring to rotate counterclockwise. The counterclockwise rotation of the drive ring in the drive hole will drive the annular pressure plate to move upward. After the annular plate can rotate, the T-shaped force bar drives the annular plate, straight pipe and fuel injection pipe to rotate clockwise. When the fuel injection pipe rotates to the top of the L-shaped protective plate, the fuel injection pipe will no longer obstruct the maintenance personnel's work.

[0023] The technical effects and advantages of this invention are as follows:

[0024] (1) The present invention utilizes the separation mechanism and the recycling mechanism. Through the cooperation between the separation box, the mounting ring, the inclined screen plate, the filter screen, the discharge box, the top block, the cylinder, the discharge pipe, the connecting pipe, the oil storage tank and the oil pump, the debris in the cold heading forming oil can be quickly removed and the cold heading forming oil can be reused. No external equipment or human intervention is required, which reduces labor costs.

[0025] (2) The present invention utilizes the setting of the reversing component. Through the cooperation between the circular box, drive hole, straight pipe, annular rotating plate, annular pressure plate, drive ring and connecting hose, the oil injection pipe can be turned away from the maintenance area when repairing a multi-station cold heading machine. There is no need for maintenance personnel to disassemble and install the oil injection pipe, which improves the convenience of maintenance work.

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

[0042] Working principle of this invention:

[0043] When debris from damaged punches, dies, and production parts appears in the multi-station cold heading machine, the debris, driven by the cold heading forming oil sprayed from the oil spray pipe 307, passes through the discharge port 201 and the separation inlet 203 and enters the separation box 202. The debris and cold heading forming oil entering the separation box 202 undergo a secondary solid-liquid separation process through the inclined screen plate 211 and the filter screen 212. Small-volume debris after solid-liquid separation remains at the top of the filter screen 212, while large-volume debris and the produced parts remain on the inclined screen plate 211. Temporarily, when the top material block 216 moves downward under the drive of the cylinder 217 and is aligned with the inclined surface of the discharge inlet 214, large-volume debris and parts from the production area will enter the discharge box 213 and eventually be discharged from the discharge pipe 215 during the upward reset movement of the top material block 216. The filtered cold heading forming oil will be stored in the separation box 202. Since the separation box 202 and the oil storage tank 303 are connected by the connecting pipe 302, the cold heading forming 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, first rotate the two threaded rods 219 counterclockwise through the two force balls 221. After the two threaded rods 219 are completely disengaged from the locking hole 220, the two force balls 221 can drive the switch plate 206 to rotate. After the switch plate 206 rotates away from the top of the separation box 202, apply a vertical upward force to the U-shaped pull rod 209 to drive the mounting ring 210 to disengage from the separation box 202. Then, invert the mounting ring 210 and tap the filter screen 212 to remove the small debris on the filter screen 212. Then, repeat the above operation 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 obstructs 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. The drive ring 3098, rotating counterclockwise within the drive hole 3092, will drive the annular pressure plate 3097 to move upward. After the annular rotating plate 3096 can rotate, the T-shaped force bar 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 above the L-shaped protective plate 4, the fuel injection pipe 307 will no longer obstruct the maintenance personnel's work.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.

9. A method of using a multi-station cold heading machine according to any one of claims 1-8, characterized in that, The specific steps include the following: Step 1: When debris caused by damage to punches, dies, and production parts appears in the multi-station cold heading machine, the debris will be driven by the cold heading forming oil sprayed from the oil spray pipe (307) to pass through the discharge port (201) and the separation inlet (203) and enter the separation box (202). The debris and cold heading forming oil entering the separation box (202) will complete the secondary solid-liquid separation step through the inclined screen plate (211) and the filter screen (212). After solid-liquid separation, small-volume debris will stay at the top of the filter screen (212), while large-volume debris and the produced parts will remain on the inclined screen plate (211). Temporarily, when the top block (216) moves downward under the drive of the cylinder (217) and is aligned with the inclined surface of the discharge inlet (214), large-volume debris and parts from the production area will enter the discharge box (213) and will eventually be discharged from the discharge pipe (215) during the upward reset movement of the top block (216). The filtered cold heading forming oil will be stored in the separation box (202). Since the separation box (202) and the oil storage tank (303) are connected by the connecting pipe (302), the cold heading forming 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 screen (212), first rotate the two threaded rods (219) counterclockwise through the two force balls (221). After the two threaded rods (219) are completely disengaged from the locking hole (220), the two force balls (221) can drive the switch plate (206) to rotate. After the switch plate (206) rotates away from the top of the separation box (202), apply a vertical upward force to the U-shaped pull rod (209) to drive the mounting ring (210) to disengage from the separation box (202). Then, invert the mounting ring (210) and tap the filter screen (212) to remove the small debris on the filter screen (212). Then, repeat the above operation in reverse to reset the mounting ring (210), switch plate (206) and two threaded rods (219). Step 3: When the oil injection pipe (307) obstructs the maintenance personnel from performing maintenance work on the multi-station cold heading machine, the drive ring (3098) is driven to rotate counterclockwise by the auxiliary rod (30913). The drive ring (3098) rotating counterclockwise in the drive hole (3092) will drive the annular pressure plate (3097) to move upward. After the annular rotating plate (3096) can rotate, the annular rotating plate (3096), straight pipe (3095) and oil injection pipe (307) will rotate clockwise by the T-shaped force bar (30910). When the oil injection pipe (307) rotates to the top of the L-shaped protective plate (4), the oil injection pipe (307) will no longer obstruct the maintenance personnel's maintenance work.
