The side of the thread block 206 passes through the limit rod 205, and the two ends of the limit rod 205 are fixedly connected to the inner wall of the bolt rolling machine body 101. The shape of the knocking rod 207 is set to be L-shaped. The collection box 202 can effectively collect waste chips and dust generated during processing, reducing the pollution of these waste materials to the working environment and the surrounding environment. The design of the clean collection box 202 makes it easy to clean and dispose of waste chips and dust, reducing the time and cost of maintenance work.

[0030] In this embodiment, waste chips generated during processing are collected by the collection box 202, and the reciprocating screw 204 is driven to rotate by the motor 203, and the rotation of the reciprocating screw 204 drives the threaded block 206 to move horizontally, and the threaded block 206 is limited by the limiting rod 205 on the side of the threaded block 206, and the displacement of the threaded block 206 drives the knocking rod 207 to move, so that the knocking rod 207 knocks the collection box 202, so that the waste chips and dust on the inner wall of the collection box 202 fall to the bottom of the collection box 202, and the water in the water tank 208 is sprayed out through the outlet pipe 209, thereby achieving the purpose of cleaning the collection box 202.

[0031] Example 2

[0032] like Figure 3 to Figure 5As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes a bolt thread rolling machine with a protective mechanism, the inner wall of the bolt thread rolling machine body 101 is fixedly connected with a telescopic rod 210, the telescopic end of the telescopic rod 210 is fixedly connected with a mounting plate 212, the side of the collection box 202 is fixedly connected with a storage box 213, the bottom of the thread block 206 is fixedly connected with a scraper 214, and the side of the scraper 214 is fixedly connected with a fixed rod 215. The collection box 202 is located on the movement track of the knocking rod 207, and the inner wall of the bolt thread rolling machine body 101 is fixedly connected with a spring 211, and one end of the spring 211 away from the bolt thread rolling machine body 101 is fixedly connected to the side of the mounting plate 212. The initial state of the spring 211 is a relaxed state, the side of the mounting plate 212 is in contact with the side of the collection box 202, and the mounting plate 212 is located on the movement track of the fixing rod 215.

The number of the springs 211 is set to be two, and they are symmetrical along the vertical center axis of the collection box 202. The number of the mounting blocks 201 is set to be two, and they are symmetrical along the vertical center axis of the collection box 202. The symmetry of the limit rod 205 is consistent with the length of the reciprocating screw rod 204. A servo motor 103 is arranged on the top of the bolt thread rolling machine body 101, a handle 104 is fixedly connected to the top of the servo motor 103, and a roller 108 is fixedly connected to the output shaft of the servo motor 103.

A handle 107 is provided on the front side of the bolt thread rolling machine body 101, and the number of rollers 102 is set to be several, and they are symmetrical with each other along the vertical center axis of the bolt thread rolling machine body 101. The horizontal displacement of the scraper 214 and the fixed rod 215 can effectively scrape off the waste and dust on the inner wall of the collection box 202 to ensure that the collection box 202 remains clean, thereby ensuring the cleanliness of the processing environment. The waste and dust scraped off by the scraper 214 will be directly collected into the storage box 213, which is convenient for subsequent cleaning and processing, reducing the tedious steps in the cleaning process.

[0033] In this embodiment, the displacement of the threaded block 206 drives the scraper 214 to move horizontally, thereby achieving the effect of scraping off the waste and dust on the inner wall of the collection box 202. The displacement of the scraper 214 drives the fixing rod 215 to move horizontally, and then the fixing rod 215 is displaced so that the fixing rod 215 first contacts the mounting plate 212. The fixing rod 215 pushes the mounting plate 212 to move, and the telescopic rod 210 and the spring 211 on the side of the mounting plate 212 are compressed. When the mounting plate 212 is pushed open, the waste scraped off by the scraper 214 enters the interior of the storage box 213 for easy cleaning. When the threaded block 206 moves to the middle position, the elastic force of the spring 211 and the telescopic rod 210 push the mounting plate 212 back to its original position, so that the side of the collection box 202 is again covered by the mounting plate 212 to continue to collect waste, thereby achieving the effect of collecting waste.
