Description

Technical Field

[0001] This utility model relates to the field of steel bar straightening technology, specifically a steel bar straightening machine for civil engineering. Background Technology

[0002] Reinforcing steel is an indispensable basic material in civil engineering. After cutting or using reinforcing steel, it may deform, which is not conducive to the use of the cut steel or the reuse of the recycled steel. Therefore, reinforcing steel straightening machines or steel straightening machines are usually used to straighten the steel. Specifically, the straightening rollers rotate and drive the steel to apply pressure during the movement, so that the bent part of the steel is straightened by pressure.

[0003] The existing equipment is not convenient for removing dust from the outer surface of the steel bars during actual use, which causes the dust to contaminate the straightening machine and is also inconvenient to operate.

[0004] For example, the steel bar straightening machine for civil engineering disclosed in announcement number CN222036626U first humidifies the outer surface of the steel bar through the washing component, and then brushes the dust on the outer surface of the steel bar with bristles. This effectively avoids dust flying everywhere when the bristles are brushing the dust, and effectively ensures the efficiency of cleaning the dust around the steel bar.

[0005] However, the device requires manual feeding of the steel bars when straightening them. During the straightening process, the steel bars may rotate or swing, which could cause injury to the workers.

[0006] Therefore, we urgently need to provide a steel bar straightening machine for civil engineering. Utility Model Content

[0007] The purpose of this utility model is to provide a steel bar straightening machine for civil engineering, so as to solve the problem mentioned in the background art that when straightening steel bars, manual feeding of steel bars is required, and the steel bars may rotate or swing during the straightening process, causing injury to workers.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a steel bar straightening machine for civil engineering, including a support frame and a material insertion hole, wherein the material insertion hole is opened on the left and right sides inside the support frame, and a straightening device is provided inside the support frame and on the left side, wherein the straightening device includes a feeding mechanism, a straightening mechanism and a dust removal mechanism.

[0009] The feeding mechanism is located on the left side of the support frame, the straightening mechanism is located inside the support frame, and the dust removal mechanism is located above the support frame.

[0010] The feeding mechanism includes a bracket, a movable plate, a side plate, a spring, a damping rod, a vertical plate, a telescopic component one, a clamping plate, and a telescopic component two. The bracket is fixedly installed on the left side of the support frame. The front and rear ends of the movable plate are slidably connected to the inner wall of the bracket. The side plate is fixedly installed on the top right side of the movable plate. The spring is fixedly installed on the front and rear ends of the left side of the side plate. The damping rod is installed inside the spring. The vertical plate is slidably connected to the front and rear sides of the top of the movable plate. The telescopic component one is fixedly installed on the upper end of the opposite side of the two vertical plates.

The output end of the telescopic component two is fixedly connected to the right side of the side plate. By activating the telescopic component one, the clamping plate is moved to clamp one end of the steel bar. Then, the telescopic component two is activated to pull the movable plate to move the steel bar to the right along the sliding groove, thereby realizing the feeding of the steel bar.

[0012] Preferably, a rectangular groove is formed on the upper surface of the movable plate, and the left end of the spring and damping rod is fixedly connected to the right side of the upright plate to prevent the steel bar from being pulled between the plate and the clamp.

The motor is fixedly installed on the back of the support frame, the output shaft is fixedly installed at the output end of the motor, the driven shaft is rotatably connected inside the support frame and located above the output shaft, the gear is fixedly installed on the outside of the output shaft and the driven shaft, and the straightening wheel is fixedly installed on the front of the output shaft and the driven shaft.

[0014] Preferably, there are multiple straightening mechanisms, which are equidistantly distributed inside the support frame, and the steel bars are straightened and transported through multiple straightening mechanisms.

[0015] Preferably, the dust removal mechanism includes a dust collection box, a fan, a connecting pipe, and a cover. The dust collection box is installed on the back of the support frame, the fan is installed on the left side of the dust collection box, the connecting pipe is connected to the top of the dust collection box, and the cover is connected to the end of the connecting pipe away from the dust collection box.

[0016] Preferably, the dust collection box is equipped with a filter screen inside, and an air outlet pipe is connected to the back of the dust collection box. During the straightening process of the steel bars, the dust generated during the straightening process is drawn into the dust collection box through the connecting pipe by the fan, and filtered by the filter screen inside the dust collection box, so that the dust is retained in the dust collection box, and the air is discharged through the air outlet pipe.

[0025] 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.

[0026] Example 1:

[0027] Currently, existing technology requires manual loading of rebars during straightening. This process can cause the rebars to rotate or sway, posing a risk of injury to workers. Please refer to [link / reference needed]. Figures 1-4This embodiment provides a steel bar straightening machine for civil engineering, which eliminates the need for manual feeding by workers and prevents the steel bars from rotating or swinging during straightening, thus avoiding injury to workers. The steel bar straightening machine includes a support frame 1 and material insertion holes 2. The material insertion holes 2 are located on the left and right sides inside the support frame 1. Straightening devices are installed inside the support frame 1 and on its left side. The straightening devices include a feeding mechanism, a straightening mechanism, and a dust removal mechanism.

[0028] The feeding mechanism is located on the left side of the support frame 1, the straightening mechanism is located inside the support frame 1, and the dust removal mechanism is located above the support frame 1.

[0029] The feeding mechanism includes a bracket 301, a movable plate 302, a side plate 303, a spring 304, a damping rod 305, a vertical plate 306, a telescopic component 1 307, a clamping plate 308, and a telescopic component 2 309. The bracket 301 is fixedly installed on the left side of the support frame 1. A groove is provided on the inner wall of the bracket 301, and the front and rear ends of the movable plate 302 are slidably connected to the inner wall of the groove. The output end of the telescopic component 2 309 is fixedly connected to the right side of the side plate 303. By activating the telescopic component 1 307, the clamping plate 308 is moved to clamp one end of the rebar. Then, by activating the telescopic component 2 309, the movable plate 302 is pulled, causing the rebar to move to the right along the groove, thereby realizing the feeding of the rebar. The front and rear ends of the movable plate 302 are slidably connected to the inner wall of the bracket 301. The side plate 303 is fixedly installed on the top right side of the movable plate 302. The spring 304 is fixedly installed on the front and rear ends of the left side of the side plate 303. The damping rod 305 is installed inside the spring 304. A groove is provided on the upper surface of the movable plate 302. The rectangular groove, spring 304, and damping rod 305 are fixedly connected to the right side of the upright plate 306 at their left ends. During the rebar feeding process, when the rebar enters between the upper and lower straightening rollers 405, the straightening rollers 405 straighten the rebar and simultaneously drive the rebar to the right. At the same time, the rebar pulls the clamping plate 308, causing the upright plate 306 to move to the right and compress the spring 304 and damping rod 305. This provides reaction time for the telescopic component 307 to drive the clamping plate 308 away from the rebar, preventing the rebar from being pulled hard against the clamping plate 308 and preventing tension between the rebar and the clamping plate 308. The upright plate 306 is slidably connected to the front and rear sides of the top of the moving plate 302. The telescopic component 307 is fixedly installed on the upper end of the opposite side of the two upright plates 306. The telescopic component 307 is an electric push rod. The clamping plate 308 is fixedly installed at the output end of the telescopic component 307. The telescopic component 309 is fixedly installed on the left side of the support frame 1. The telescopic component 309 includes a hydraulic cylinder and a hydraulic rod.

[0030] To straighten the reinforcing bars, this device is equipped with a straightening mechanism, which includes a motor 401, an output shaft 402, a driven shaft 403, a gear 404, and a straightening wheel 405. There are multiple straightening mechanisms, which are equidistantly distributed inside the support frame 1. The reinforcing bars are straightened and conveyed through multiple straightening mechanisms. The motor 401 is fixedly installed on the back of the support frame 1, the output shaft 402 is fixedly installed on the output end of the motor 401, the driven shaft 403 is rotatably connected inside the support frame 1 and located above the output shaft 402, the gear 404 is fixedly installed on the outside of the output shaft 402 and the driven shaft 403, and the straightening wheel 405 is fixedly installed on the front of the output shaft 402 and the driven shaft 403.

[0031] Example 2:

[0032] Based on Example 1, please refer to Figures 1-2 To prevent dust generated during the rebar straightening process from polluting the surrounding environment, this device is also equipped with a dust removal mechanism, which includes a dust collection box 501, a fan 502, a connecting pipe 503, and a cover 504. The dust collection box 501 is installed on the back of the support frame 1. A filter screen is installed inside the dust collection box 501, and an air outlet pipe is connected to the back of the dust collection box 501. During the rebar straightening process, the fan 502 draws the dust generated during the straightening process into the dust collection box 501 through the connecting pipe 503. After being filtered by the filter screen inside the dust collection box 501, the dust remains inside the dust collection box 501, and the air is discharged through the air outlet pipe. The fan 502 is installed on the left side of the dust collection box 501, the connecting pipe 503 is connected to the top of the dust collection box 501, and the cover 504 is connected to the end of the connecting pipe 503 away from the dust collection box 501.

[0033] In use, place one end of the rebar to be straightened between the front and rear clamping plates 308, then activate the first telescopic component 307 to push the clamping plates 308 to move and clamp one end of the rebar. Then activate the second telescopic component 309 to pull the moving plate 302 to move the rebar along the slide to the right, so that the right end of the rebar passes through the material hole 2 and enters the upper and lower straightening rollers 405. Then activate the first telescopic component 307 to move the front and rear clamping plates 308 away from the rebar to avoid pulling between the rebar and the clamping plates 308. Then straighten the rebar by squeezing it with the straightening rollers 405 and simultaneously convey the rebar to the right. During the straightening process, activate the fan 502 to draw the dust raised during the processing into the dust collection box 501 through the connecting pipe 503 for collection.
