The threading mechanism 2 includes a bracket 201, a first reducer 203, a rotating shaft flange 205, a planetary gear fixing plate 206, a dial 208, a guide shaft 210, a rib stripping knife position cylinder 211, a steel bar limiting cylinder assembly 212, and a threading wheel core shaft 214. A first servo motor 202 is provided at the top of the bracket 201. The output end shafts of the first reducer 203 and the first servo motor 202 are key-connected. A rotating main shaft 204 is provided at the front end of the first reducer 203. A support sleeve 2041 is sleeved on the outer wall of the rotating main shaft 204. The rotating shaft flange 205 is arranged between the rotating main shaft 204 and the support sleeve 2041. The other end of the planetary gear fixing plate 206 is sleeved with a threading wheel cavity 207. Three groups of threading wheel core shafts 214 are arranged at equal intervals in the inner cavity of the threading wheel cavity 207. A rolling threading wheel 2141 is sleeved on the outer wall of the threading wheel core shaft 214. The threading wheel core shaft 214 passes through the planetary gear fixing plate 206 and is integrally connected with the adjusting planetary gear 2061.

A rib stripping knife spring 2082 is arranged inside the rib stripping knife guide seat 2081. The spring helps to adapt to steel bars of different sizes. The rib stripping knife position cylinder 211 is connected to the guide shaft 210. A rib stripping knife size adjusting block 2083 is sleeved on the outer wall of the rib stripping knife guide seat 2081. A steel bar limiting rotating shaft 209 is provided at the bottom of the rib stripping knife size adjusting block 2083. The rib stripping knife size adjusting block 2083 is convenient for adjusting the size of the cutter head to adapt to work in various environments. The steel bar limiting cylinder assembly 212 is connected to one end of the steel bar limiting rotating shaft 209. A steel bar limiting baffle 213 is arranged on one side of the steel bar limiting cylinder assembly 212. The threading wheel core shaft 214 passes through the planetary gear fixing plate 206 and is integrally connected with the adjusting planetary gear 2061. When the first servo motor 202 is started, the rotation speed of the rotating main shaft 204 decreases under the action of the first reducer 203, and then drives the adjusting planetary gear 2061 to rotate. Under the rotation action of the rotating adjusting planetary gear 2061, the rib stripping blade 2091 rotates, and finally the steel bar is cut.

[0035] Refer to Figures 1 - 4, based on the same concept as the above-mentioned Embodiment 1, this embodiment also proposes that a clamping and advancing mechanism 3 is provided at the top of the support 1. The clamping and advancing mechanism 3 includes a second servo motor 301. A clamping and advancing speed reducer 302 is provided at the output end of the second servo motor 301. The output end of the clamping and advancing speed reducer 302 is connected to a synchronous belt assembly 303. The synchronous belt assembly 303 is connected to a ball screw assembly 304. There are two ball screw assemblies 304, which are arranged in parallel and symmetrically. A clamping block 305 is provided on the ball screw assembly 304. Clamping positive and negative lead screws 306 are provided on both sides of the clamping block 305. Clamping gears 3061 and racks 3062 are provided on the clamping positive and negative lead screws 306. The clamping gears 3061 and the racks 3062 are connected to the output end 307 of the top cylinder. An adjusting idler 308 is provided at the front end of the bracket 201. The adjusting idler 308 is composed of two runners with a trapezoidal cross-section on the side facing each other and is connected by a rotating shaft. Steel bars can be placed in the recessed part of the runner.

[0036] Specifically, one end of a shaft flange 205 is sleeved with a pad flange 2051. One end of the pad flange 2051 is sleeved inside a planetary gear fixing plate 206. A rib-removing tool size adjusting block 2083 is sleeved with a dial 208. A rib-removing blade 2091 is internally connected to a rib-removing tool guide seat 2081. There are 4 rib-removing blades 2091. Dial pieces 2092 are symmetrically arranged on both sides of the rib-removing tool size adjusting block 2083. The dial pieces 2092 are both connected to a guide shaft 210. A water pump 101 is provided inside the support 1. The water pump 101 can immediately provide cooling for the cutting and threading friction part to prevent damage to the device components caused by excessive temperature.

[0037] The working process or principle of this servo threading machine is as follows: Insert the steel bar into the clamping and advancing mechanism 3. At this time, the adjusting idler 308 provides a lifting effect. Then it reaches the steel bar limit baffle 213 through the clamping block 305 and contacts the steel bar limit baffle 213. The steel bar limit cylinder assembly 212 returns to the zero point. Under the action of the steel bar limit cylinder assembly 212, the output end 307 of the top cylinder drives the clamping positive and negative lead screws 306 to move downward. The clamping gear 3061 rotates to drive the ball screw assembly 304 so that the clamping block 305 clamps or loosens the steel bar. Start the first servo motor 202. Under the action of the first speed reducer 203, the rotation speed of the rotating shaft 204 decreases, and then drives the adjusting planetary gear 2061 to rotate. Under the action of the rotating adjusting planetary gear 2061, the rib-removing blade 2091 rotates and finally the steel bar is chiseled.

[0038] It should be noted that for the devices or equipment existing in the prior art, or the devices or equipment that can be realized by the prior art, their power supply, specific composition and principle are clear to those skilled in the art, so no further detailed description will be given.
