Description

Technical Field

[0001] This utility model relates to the field of wire drawing machine technology, specifically a tension adjustment mechanism for a wire drawing machine. Background Technology

[0002] Wire drawing machines are pre-processing equipment used in the production of standard parts and other metal products. Their purpose is to draw wire or bar stock transported from steel manufacturers to these production facilities, ensuring that the wire or bar stock meets the raw material processing requirements for standard parts and other metal product manufacturing in terms of diameter, roundness, internal metallographic structure, surface finish, and straightness. However, existing wire drawing machines' tension adjustment devices require repeated manual adjustments, which is cumbersome and prone to wire breakage. Furthermore, the rollers on these machines are prone to wear after prolonged use, and the current bolt-fixed rollers result in slow disassembly and replacement, affecting the overall operation of the wire drawing machine.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 In this embodiment of the present invention, a tension adjustment mechanism for a wire drawing machine includes: a bearing shell 100, two adjustment mechanisms 200 and two bearing mechanisms 300. Two guide wheels 110 are provided at both ends of one side of the bearing shell 100. The two adjustment mechanisms 200 are fixed on the bearing shell 100 and the two bearing mechanisms 300 are provided at both ends of the bearing shell 100.

[0033] Specifically, the guide wheel 110 facilitates the guidance of the wire pulled by the wire drawing machine, and the two adjustment mechanisms 200 facilitate the rapid adjustment of the wire tension. The bearing mechanism 300 facilitates the support of the guide wheel 110, and the bearing mechanism 300 enables the guide wheel 110 to be quickly disassembled and replaced, making it more convenient to use.

[0034] Example 1

[0035] like Figure 3-5 As shown, in this embodiment, the adjustment mechanism 200 includes: a fixed shell 210, a movable shell 240, a rectangular frame 250, and a fixed seat 270. The fixed shell 210 is fixedly connected to the bearing shell 100, and an adjustment component is provided on the fixed shell 210. The movable shell 240 is disposed on one side of the fixed shell 210. The rectangular frame 250 is slidably connected to the movable shell 240. A damping spring 251 is fixedly connected to one end of the rectangular frame 250, and a compression plate 252 is fixedly connected to one end of the damping spring 251. The fixed seat 270 is disposed at the other end of the rectangular frame 250. The fixed base 270 is internally rotatably connected to an adjusting roller 272. The adjustment assembly includes a motor 220 and a moving plate 230. The motor 220 is fixedly connected to an inner wall of the fixed housing 210. The output end of the motor 220 is fixedly connected to a screw 221. The moving plate 230 is slidably connected to the inside of the fixed housing 210. The moving plate 230 is screwed to the screw 221. One end of the moving plate 230 is fixedly connected to the moving housing 240. A pressure sensor 260 is fixedly connected to an inner wall of the moving housing 240. The pressing plate 252 is connected to the pressure sensor 260.

[0036] In this embodiment, by starting the motor 220, the screw 221 is rotated, thereby moving the moving plate 230, the moving shell 240, the rectangular frame 250, the fixed base 270, and the adjusting roller 272. After the adjusting roller 272 moves, it will come into contact with the wire. After the adjusting roller 272 comes into contact with the wire, the damping spring 251 will be compressed. The compressed damping spring 251 will push the pressing plate 252 to press against the pressure sensor 260. The pressure sensor 260 can be used to easily understand and control the tension of the wire drawing machine, and thus it is convenient to quickly adjust the tension of the wire drawing machine as needed, making it more convenient to use.

[0037] like Figure 4As shown, in this embodiment, a threaded hole 253 is provided at the other end of the rectangular frame 250, two limiting holes 271 are provided on the fixing seat 270, a threaded block 280 is fixedly connected to the fixing seat 270, and the threaded block 280 is screwed into the threaded hole 253. Two connecting shells 290 are fixedly connected inside the rectangular frame 250, and a limiting plate 291 is slidably connected inside the connecting shell 290. The limiting plate 291 is slidably connected to the rectangular frame 250 and the corresponding limiting hole 271. Multiple damping springs 292 are fixedly connected between the inner bottom surface of the connecting shell 290 and the limiting plate 291. A push plate 293 is fixedly connected to one side of the limiting plate 291.

[0038] In practice, by pushing the two push plates 293 outward, both limit plates 291 are moved downward, thereby separating the limit plates 291 from the limit holes 271. By rotating the fixed seat 270 and the threaded block 280, the fixed seat 270 and the adjusting roller 272 can be easily removed, thus facilitating the quick disassembly and replacement of the damaged adjusting roller 272.

[0039] In order to facilitate the operator's control of the utility model, a PLC controller can be set up, and the motor 220 and the pressure sensor 260 are electrically connected to the PLC controller. The PLC controller is existing technology and will not be described in detail here.

[0040] Example 2

[0041] Based on Embodiment 1, in order to support the guide wheel 110 and enable the guide wheel 110 to be quickly disassembled and replaced.

[0042] like Figure 6 As shown, in this embodiment, the bearing mechanism 300 includes: a fixed frame 310 and two bearing seats 320. The fixed frame 310 is fixedly connected to the bearing shell 100. The two bearing seats 320 are rotatably connected to the fixed frame 310. The two bearing seats 320 are slidably connected to the corresponding guide wheels 110. The bearing seats 320 are provided with threaded grooves 321 and limiting grooves 322. One end of the bearing seat 320 is provided with a baffle 340, and a connecting ring 341 is fixedly connected to the baffle 340. A rubber plug 332 is fixedly connected to the baffle 340, and the rubber plug 332 is slidably connected to the limiting groove 322. A telescopic rod 330 is fixedly sleeved inside the rubber plug 332, and a screw 331 is fixedly connected to one end of the telescopic rod 330. The screw 331 is screwed into the threaded groove 321.

[0043] In specific implementation, the bearing seat 320 is used to support the guide wheel 110, and the baffle 340 is used to limit the guide wheel 110 supported on the bearing mechanism 300. The rubber plug 332 is used in conjunction with the limiting groove 322 to prevent the telescopic rod 330, rubber plug 332 and baffle 340 from moving after installation. When the guide wheel 110 is damaged, the telescopic rod 330 is extended by pulling the connecting ring 341, baffle 340 and rubber plug 332 outward, and the rubber plug 332 is separated from the limiting groove 322. Then, by rotating the connecting ring 341, baffle 340, rubber plug 332, telescopic rod 330 and screw 331, the connecting ring 341, baffle 340, rubber plug 332, telescopic rod 330 and screw 331 can be disassembled, thus facilitating the quick disassembly and replacement of the guide wheel 110.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
