Description

Technical Field

[0001] This utility model relates to the field of steel bar production technology, specifically to a pushing device for steel bar production. Background Technology

[0002] Steel bars are steel materials used in reinforced concrete and prestressed reinforced concrete. They are mainly divided into two categories: plain round steel bars and deformed steel bars (ribbed steel bars). They are widely used in building structures, especially large and high-rise buildings. The steel bar production process includes steelmaking, refining, continuous casting, hot rolling, cold drawing and cutting.

[0003] Currently, in the process of steel bar production, a pushing device is used to move the steel bars. However, the existing steel bar pushing device does not have a cutting structure and cannot cut the steel bars as needed. Therefore, a pushing device for steel bar production is proposed, in which a geared motor drives a V-shaped conveying roller to rotate and push the steel bars, and a cylinder works to push the steel blade downward to cut the steel bars during their movement. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a pushing device for steel bar production. A geared motor drives a V-shaped conveying roller to rotate and push the steel bar, while a cylinder pushes a steel cutter downward to cut the steel bar during its movement.

[0005] The technical solution adopted by this utility model to solve its technical problem is a pushing device for steel bar production, including a base plate, a pushing component, a cutting component, a pressing component, and a telescopic component. The telescopic component is disposed on the top of the base plate, and the pushing component is disposed on the top of the telescopic component. The pushing component includes a concave seat, and V-shaped conveying rollers are equidistantly connected inside the concave seat through bearings. A first synchronous pulley is fixedly sleeved on one end of the V-shaped conveying roller located outside the concave seat through a flat key. A reduction motor is mounted on the bottom of the concave seat through a mounting bracket. A second synchronous pulley is fixedly sleeved on one side of the output shaft of the reduction motor through a flat key.

A cylinder is mounted on the top of the first gantry frame by a mounting bracket. A steel knife is fixed to the output shaft of the cylinder inside the first gantry frame by bolts.

[0007] By adopting the above technical solution, the geared motor drives the V-shaped conveyor roller to rotate through the first synchronous pulley, the second synchronous pulley and the synchronous belt, which pushes the steel bar to move. The cylinder pushes the steel blade to move down and cut the steel bar.

[0008] Specifically, a limiting roller is rotatably connected to one side of the concave seat via a bearing, and a knife groove corresponding to the steel knife is opened inside the arc-shaped groove.

[0009] Specifically, the bottom of the base plate is fixed with brakeable omnidirectional wheels at equal intervals by bolts, the telescopic assembly includes a plate sleeve fixed to the top of the base plate by bolts, a support plate is sleeved on the top of the plate sleeve, and the concave seat is fixed to the top of the plate sleeve by bolts.

[0010] Specifically, one side of the plate sleeve is connected to a fixing bolt via a threaded groove, and one side of the support plate is provided with slots corresponding to the plate sleeve at equal intervals.

[0011] Specifically, the pressing assembly includes a second gantry frame fixed to the top of the concave seat by bolts. An internal threaded sleeve is welded to the top of the second gantry frame.

The deceleration motor drives multiple V-shaped conveying rollers to rotate through the second synchronous wheel, the synchronous belt and the first synchronous wheel to push the steel bars. The cylinder is opened to push the steel blade down, which can cut the steel bars moving in the arc groove.

[0015] (2) The present invention provides a pushing device for steel bar production, wherein rotating the long screw pushes the structural frame down through the internal threaded sleeve, and pressing the steel bar onto the V-shaped conveying roller through the pressure roller, and moving the support plate up and down to adjust the height of the concave seat according to the height of the steel bar production line.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] A geared motor drives a V-shaped conveyor roller to push the reinforcing bar, while a cylinder pushes a steel cutter downwards to cut the bar during its movement. Figure 1-5 As shown, the present invention discloses a pushing device for producing steel bars, comprising a base plate 1, a pushing component 2, a cutting component 3, a pressing component 4, and a telescopic component 5. The telescopic component 5 is disposed on the top of the base plate 1, and the pushing component 2 is disposed on the top of the telescopic component 5. The pushing component 2 includes a concave seat 201, and V-shaped conveying rollers 202 are equidistantly connected inside the concave seat 201 via bearings. A first synchronous wheel 204 is fixedly sleeved on one end of the V-shaped conveying roller 202 located outside the concave seat 201 via a flat key. A reduction motor 203 is mounted on the bottom of the concave seat 201 via a mounting bracket. A second synchronous wheel 205 is fixedly sleeved on one side of the output shaft of the reduction motor 203 via a flat key. A synchronous belt 206 is sleeved on the outer side of the second synchronous wheel 205 and the first synchronous wheel 204.

[0025] The cutting component 3 is disposed at one end of the concave seat 201. The cutting component 3 includes a base 301 fixed to one end of the concave seat 201 by bolts. The top of the base 301 is provided with an arc groove 302. The top of the base 301 located outside the arc groove 302 is fixed to a first gantry frame 303 by bolts. The top of the first gantry frame 303 is mounted with a cylinder 304 by a mounting bracket. The output shaft of the cylinder 304 located inside the first gantry frame 303 is fixed to a steel knife 305 by bolts.

[0026] In use, the geared motor 203 drives the V-shaped conveyor roller 202 to rotate through the first synchronous pulley 204, the second synchronous pulley 205 and the synchronous belt 206, which pushes the steel bar to move. The cylinder 304 pushes the steel knife 305 to move down to cut the steel bar.

[0027] For example, such as Figure 3 , Figure 4 As shown, the present invention also includes a limiting roller 207 rotatably connected to one side of the concave seat 201 via a bearing, and a knife groove 306 corresponding to the steel knife 305 is provided inside the arc groove 302.

[0028] When in use, the setting of the limiting roller 207 allows the synchronous belt 206 to be close to one side of the first synchronous pulley 204, and the opening of the knife groove 306 prevents the steel knife 305 from hitting the arc groove 302 when cutting the steel bar.

[0029] For example, such as Figure 2 As shown, the present invention also includes brakeable universal wheels 6 that are equidistantly fixed to the bottom of the base plate 1 by bolts, the telescopic assembly 5 including a plate sleeve 501 fixed to the top of the base plate 1 by bolts, a support plate 502 sleeved on the top of the plate sleeve 501, and the concave seat 201 fixed to the top of the plate sleeve 501 by bolts.

[0030] When in use, the brakeable caster 6 facilitates the movement of the base plate 1, and the support plate 502 is sleeved on the top of the plate sleeve 501, allowing it to move up and down.

[0031] For example, such as Figure 2 As shown, the present invention also includes a fixing bolt 503 connected to one side of the plate sleeve 501 through a threaded groove, and a slot 504 corresponding to the plate sleeve 501 is provided on one side of the support plate 502 at equal intervals.

[0032] When in use, tighten the fixing bolt 503 so that one end is inserted into the corresponding slot 504 to fix the support plate 502 after it moves up and down.

[0033] For example, such as Figure 5 As shown, the present invention also includes a pressing assembly 4 comprising a second gantry frame 401 fixed to the top of the concave seat 201 by bolts. An internal threaded sleeve 402 is welded to the top of the second gantry frame 401. A long screw 403 is sleeved through the internal threaded sleeve 402. The bottom end of the long screw 403 located inside the second gantry frame 401 is connected to a structural frame 404 by a bearing. A pressing roller 405 is rotatably connected inside the structural frame 404 by a bearing.

[0034] In use, rotating the long screw 403 pushes the structural frame 404 and the pressure roller 405 at its bottom downward through the internal threaded sleeve 402, pressing the steel bar onto the V-shaped conveyor roller 202.

[0035] For example, such as Figure 5 As shown, the present invention also includes auxiliary rods 406 connected to the top two ends of the structural frame 404 through threaded grooves, and the auxiliary rods 406 penetrate the second gantry frame 401.

[0036] When in use, the auxiliary rod 406 can prevent the structural frame 404 from tilting or rotating without affecting its vertical movement.

[0037] In use, personnel move the base plate 1 onto the steel rebar production line using the brakeable casters 6, connect the device to an external power source using a power cord, connect the device to an external air supply device using the air cylinder 304, adjust the height of the concave seat 201 according to the height of the steel rebar production line by moving the support plate 502 up and down, tighten the fixing bolts 503 so that one end of the bolts is inserted into the corresponding slot 504, and fix the support plate 502 after it has moved up and down.

[0038] When one end of the reinforcing bar is moved onto the V-shaped conveying roller 202 inside the concave seat 201, the long screw 403 is rotated to push the structural frame 404 down through the inner threaded sleeve 402, and the reinforcing bar is pressed onto the V-shaped conveying roller 202 by the pressing roller 405.

[0039] Turn on the geared motor 203 to drive the second synchronous pulley 205 to rotate, and drive the first synchronous pulley 204 and V-shaped conveyor roller 202 to rotate through the synchronous belt 206. The rotation of multiple V-shaped conveyor rollers 202 pushes the steel bars. The setting of the limiting roller 207 allows the synchronous belt 206 to be close to the outside of the first synchronous pulley 204.

[0040] When it is necessary to cut the reinforcing bar, the cylinder 304 is opened to push the steel blade 305 downward. The steel blade 305 cuts the reinforcing bar moving in the arc groove 302. The opening of the blade groove 306 ensures that the steel blade 305 will not hit the arc groove 302 when cutting the reinforcing bar.
