Description

Technical Field

[0001] This utility model belongs to the field of rebar thread processing technology, specifically relating to a rebar thread grinding machine. Background Technology

[0002] Rebar threading refers to creating threads at one or both ends of a rebar to allow it to be connected to other rebars or embedded parts using nuts and washers. This method is widely used in building construction, especially in situations requiring rebar splicing, anchoring, and assembly of precast components.

[0003] After being cut to the appropriate length, the ends of reinforcing bars are often uneven and require manual grinding to smooth them before further processing to create rebar threads. However, manual grinding of the rebar ends is time-consuming, labor-intensive, and inefficient, impacting project progress. Therefore, a new type of rebar thread grinding machine is needed.

[0029] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0030] Please see Figure 1-7 A rebar wire grinding machine includes an integral frame 1. A quantitative discharge component 2 is mounted on the top of the integral frame 1, a fixing component 3 is located at the bottom outlet of the quantitative discharge component 2, and a grinding component 4 is located at the sliding outlet of the fixing component 3. Multiple rebars are stored in the quantitative discharge component 2 and released one by one from its bottom outlet into the fixing component 3. Individual rebars falling into the fixing component 3 are temporarily fixed, and then the grinding component 4 grinds the ends of the rebars flat for subsequent processing.

[0031] The quantitative discharge assembly 2 includes a storage hopper 201 fixedly connected to the overall frame 1 and inclined. A vibrator 202 is fixedly installed on the side wall of the storage hopper 201. Adjustable blades 203 are rotatably installed on both sides of the bottom strip-shaped opening of the storage hopper 201, and a control blade 204 is rotatably installed at the bottom of each adjustable blade 203. A curved spring 205 is fixedly connected to each control blade 204, and the other end of the curved spring 205 is fixedly connected to the adjustable blade 203 above. An angle adjustment seat 206 is fixedly installed on the lower side wall of the storage hopper 201. A rod 207 slides out from the end of each adjustable blade 203 near the angle adjustment seat 206, and the angle adjustment seat 206 has several double-arc distributed through holes adapted to the rods 207. The through holes of the angle adjustment seat 206 are double-arc distributed and adapted to two rods 207 respectively. Pulling the insertion rod 207 disengages it from the angle adjustment seat 206, allowing the adjustable blade 203 to rotate. This adjusts the size of the opening between the two adjustable blades 203, accommodating individual steel bars of different diameters. When the vibrator 202 starts, a single steel bar is squeezed out and falls through the opening between the two adjustable blades 203. The control blade 204 rotates and opens, causing the bending spring 205 to undergo elastic deformation.

[0032] The top and upper sidewall of the storage hopper 201 are open, and the handle of each insert 207 extends from the adjustable blade 203. Each insert 207 is connected to a spring 208, and the other end of the spring 208 abuts against the inner wall of the adjustable blade 203. The spring 208 is always in a compressed state. A detector 209 is installed on the sidewall of the angle adjustment seat 206, facing the opening between the two adjustable blades 203. The detector 209 is used to detect a single rebar falling between the two adjustable blades 203.

[0033] The fixing component 3 includes a fixing hopper 301 fixedly connected to the overall frame 1 and inclined in the same direction as the storage hopper 201. The top of the fixing hopper 301 opens only towards the bottom outlet side of the metering dispensing component 2. The upper side wall of the fixing hopper 301 is fully open, and the bottom of the lower side wall of the fixing hopper 301 is open. The bottom opening of the lower side wall of the fixing hopper 301 is the sliding outlet of the fixing component 3. A moving plate 302 is blocked at one bottom opening of the fixing hopper 301, and a first telescopic rod 303 fixedly connected to the overall frame 1 extends from the moving plate 302. A second telescopic rod 304 extends from the top of the inner cavity of the fixing hopper 301, and a pressure rod 305 parallel to the moving plate 302 is fixedly connected to the bottom of the second telescopic rod 304.

[0034] A third telescopic rod 306 is fixedly installed on the lower side wall of the fixed hopper 301, and a baffle 307 with an opening facing the bottom of the lower side wall of the fixed hopper 301 is fixedly connected to the telescopic end of the third telescopic rod 306. The baffle 307 does not contact the fixed hopper 301. After a single steel bar falls into the fixed hopper 301, the steel bar slides down naturally and its bottom abuts against the baffle 307. Then, the second telescopic rod 304 extends, so that the pressure rod 305, together with the fixed hopper 301 and the moving plate 302, fixes the steel bar. Then, the third telescopic rod 306 pulls the baffle 307 upward, and the grinding component 4 grinds the end of the steel bar flat. Finally, the first telescopic rod 303 retracts, the moving plate 302 disengages from the fixed hopper 301, and the steel bar falls out of the fixed hopper 301. After the steel bar falls out of the fixed hopper 301, the moving plate 302 returns to its original position and adheres to the fixed hopper 301.

[0035] The grinding assembly 4 includes a slide rail 401 fixedly connected to the integral frame 1. A T-shaped slider 403 is slidably connected to the slide rail 401, and a motor 404 is connected to the T-shaped slider 403. A grinding disc 405 is coaxially fixedly connected to the output shaft of the motor 404, and the grinding disc 405 faces the sliding outlet of the fixed assembly 3. A fourth telescopic rod 402 is connected to one end of the motor 404 away from the grinding disc 405, and the other end of the fourth telescopic rod 402 is fixedly connected to the slide rail 401. After the reinforcing bar is fixed in the fixed hopper 301, the motor 404 drives the grinding disc 405 to rotate, and the fourth telescopic rod 402 extends, driving the grinding disc 405 closer to the end of the reinforcing bar, thereby grinding the end of the reinforcing bar flat. The grinding plane of the grinding disc 405 is perpendicular to the reinforcing bar.

[0036] The T-shaped slider 403 is connected to the top of the motor 404. Because the slide rail 401 is inverted, the dust generated during grinding enters the slide rail 401, reducing the dust's impact on the slide rail 401.

[0037] Working principle:

[0038] When in use, the steel bars are stored in the storage hopper 201. Then the vibrator 202 is started, and a single steel bar is squeezed out from the opening between the two adjustable blades 203. The control blade 204 rotates and opens, and the bending spring 205 undergoes elastic deformation. When a single steel bar falls, it is immediately detected by the detector 209. At this time, the vibrator 202 is turned off, so that one steel bar falls out of the storage hopper 201 at a time.

[0039] Then, a single steel bar falls into the fixed hopper 301, slides down naturally and its bottom abuts against the baffle 307. Next, the second telescopic rod 304 extends, so that the pressure rod 305, together with the fixed hopper 301 and the moving plate 302, fixes the steel bar. Then, the third telescopic rod 306 pulls the baffle 307 upward, and the grinding component 4 grinds the end of the steel bar flat. Finally, the first telescopic rod 303 retracts and the moving plate 302 disengages from the fixed hopper 301, and the steel bar falls out of the fixed hopper 301.

[0040] When the grinding component 4 grinds the end of the steel bar, the motor 404 drives the grinding disc 405 to rotate, and the fourth telescopic rod 402 extends to drive the grinding disc 405 to approach the end of the steel bar, thereby grinding the end of the steel bar flat.

[0041] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
