Description

Technical Field

[0001] The utility model relates to the technical field of bolt processing, and specifically, to a bolt thread rolling device with a chip removal function. Background Art

[0002] A bolt thread rolling device is a mechanical device used for processing bolt threads. Through the interaction between two thread rolling plates with the same thread shape, the thread is pressed or rolled into the bolt blank to form a thread. This device is usually used in mass production to improve production efficiency and the quality of thread processing. A bolt thread rolling device with a chip removal function is a bolt processing equipment that can effectively remove chips during the bolt processing to keep the working environment clean and improve processing efficiency.

[0003] In the prior art, a thread rolling machine uses a static thread rolling head and a dynamic thread rolling head to roll threads on bolts. After the bolts are thread rolled, metal chips are likely to remain on the static thread rolling head and the dynamic thread rolling head. Since it is necessary to drip oil on the friction surfaces of the thread rolling plates and the bolts, under the action of the lubricating oil, the metal chips will disengage from the static thread rolling head and the dynamic thread rolling head. However, the used lubricating oil often cannot be directly reused because it is mixed with metal chips and wear particles, which not only increases the treatment cost but also causes waste of resources.

[0013] The working principle and beneficial effects of the present utility model are as follows:

[0014] In the present utility model, by starting the oil pump, the oil pump extracts lubricating oil from inside the fuel tank through the input pipe, and then transports it to the fuel injection rack through the output pipe. Then, the fuel injection rack sprays it through the nozzles to lubricate the static rubbing head and the dynamic rubbing head. When the lubricating oil lubricates the static rubbing head and the dynamic rubbing head, the excess lubricating oil drives the iron filings to drip onto the filter screen above the inside of the fuel tank together. Through the filtration of the filter screen, the lubricating oil drips into the inside of the fuel tank, and the iron filings adhere to the filter screen. Start the electric push rod, and the electric push rod pushes the mounting shell. The mounting shell drives the scraper to move to clean the filter screen and scrape off the iron filings and push them forward. When the scraper moves forward, it is blocked by the stopper and contracts into the mounting shell. When the scraper contracts, it compresses the first spring, causing the first spring to generate an elastic force. The mounting shell moves forward to push the baffle, and pushes the iron filings into the waste chip box to be discharged, realizing the separation of iron filings and impurities in the lubricating oil and improving the utilization efficiency of resources. In the present utility model, by pulling the bolt to drive the sliding block to squeeze the third spring until the bolt completely disengages from inside the adjusting rod, at this time, the adjusting rod can be pulled to adjust the static rubbing head to a suitable position, thereby adjusting the distance between the static rubbing head and the dynamic rubbing head to match bolts of more specifications, with high versatility. When the sliding block slides outwards, the blocking block will slide into the inside of the outer shell, enabling the worker to free both hands, reducing the operation difficulty and labor intensity, and improving the practicality of the device.

On the side of the two adjusting rods 8 close to the moving thread rolling head 5, a static thread rolling head 9 is fixedly connected. Fixed components are arranged on both sides of the adjusting rods 8 after being clamped. On the edge of the top of the workbench 1, an oil pump 10 is fixedly connected. The input end of the oil pump 10 is fixedly connected with an input pipe 11. One end of the input pipe 11 away from the oil pump 10 is fixedly connected with an oil tank 12. The bottom of the oil tank 12 is fixedly connected to the bottom of the workbench 1. A filter screen 13 is fixedly connected inside the oil tank 12. Two stoppers 14 are fixedly connected to the right side of the top of the filter screen 13. An electric push rod 15 is fixedly connected to the left side of the oil tank 12. The output end of the electric push rod 15 is fixedly connected with a mounting shell 16. Two first springs 17 are arranged inside the mounting shell 16. Scrapers 18 are slidably connected to the front and back sides inside the mounting shell 16. A waste chip box 19 is fixedly connected to the right side of the oil tank 12. A baffle 20 is slidably connected inside the waste chip box 19. A plurality of second springs 21 are arranged inside the waste chip box 19. The output end of the oil pump 10 is fixedly connected with an output pipe 22. One end of the output pipe 22 away from the oil pump 10 is fixedly connected with an oil injection rack 23. The bottom of the oil injection rack 23 is fixedly connected to the top of the oil pump 10. Nozzles 24 are fixedly connected to the bottom of the oil injection rack 23.The purpose of this setting is that when in use, the blank is placed between the moving rubbing head 5 and the static rubbing head 9. The motor 2 is started, and the motor 2 drives the turntable 3 to rotate. The turntable 3 drives the connecting rod 4, and the connecting rod 4 drives the moving rubbing head 5 to slide back and forth inside the slide rail 6 to process the bolt blank. When lubrication is required, the oil pump 10 is started. The oil pump 10 extracts lubricating oil from the inside of the fuel tank 12 through the input pipe 11, and then transports it to the oil spray rack 23 through the output pipe 22. Then, the oil spray rack 23 sprays it through the nozzles 24 to lubricate the static rubbing head 9 and the moving rubbing head 5. When the lubricating oil lubricates the static rubbing head 9 and the moving rubbing head 5, the excess lubricating oil drives the iron filings to drip onto the filter screen 13 above the inside of the fuel tank 12 together. Through the filtration of the filter screen 13, the lubricating oil drips into the inside of the fuel tank 12, and the iron filings adhere to the filter screen 13. The electric push rod 15 is started, and the electric push rod 15 pushes the installation shell 16. The installation shell 16 drives the scraper 18. When the scraper 18 moves, it cleans the filter screen 13 and scrapes off the iron filings and pushes them forward. When the scraper 18 moves forward and is blocked by the stop block 14, it contracts into the installation shell 16.
