Description

Technical Field

[0001] This invention relates to the field of steel bar cutting technology, specifically to a steel bar cutting device for building construction. Background Technology

[0002] In the field of construction, steel bars of various sizes are often needed. Before use, steel bars often need to be cut by a cutting machine to obtain the required size.

[0003] When existing cutting machines are used for cutting steel bars, the operator usually needs to hold the cutting machine with one hand and limit the steel bar with the other hand. Only one steel bar can be cut at a time, resulting in low cutting efficiency. When the steel bar to be cut shakes, the cutting tool is prone to breakage, and there is a significant safety hazard.

[0004] For example, a rebar cutting machine with Chinese Patent Publication No. CN112620540B includes a control rod movably connected to the upper end of a base. A grinding wheel cover is fixedly connected to one side of the control rod. A grinding wheel is installed inside the grinding wheel cover. A motor is fixedly connected to one side of the grinding wheel cover. A drive shaft is provided between the grinding wheel cover and the grinding wheel. A fixed cover is engaged at one end of the drive shaft. This device can prevent debris from flying onto the operator, and the design of the compressed air groove reduces the pressure of the airflow on the pressure plate under high-speed rotation.

[0005] However, in actual use, the device still requires a worker to hold a control lever and press down the cutting machine to cut individual steel bars one by one, resulting in low cutting efficiency. Therefore, this application provides a steel bar cutting device for building construction to solve the problem of low steel bar cutting efficiency in the prior art. Summary of the Invention

[0006] To address the above problems, the present invention provides a steel bar cutting device for building construction.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a steel bar cutting device for building construction, comprising two supporting parts for supporting the steel bar to be cut. Each supporting part includes a support base and several telescopic cylinders arranged in a staggered manner. The movable end of each telescopic cylinder is connected to a clamping plate. Multiple continuous >-shaped clamping grooves are formed between the clamping plates. An auxiliary wheel is connected to the middle of each clamping plate. The two sides of the auxiliary wheel are movable sections. The movable sections are equipped with telescopic components, which are used to push the movable sections to clamp the steel bar to be cut. The cutting section, located between the two supporting sections, is used to cut the reinforcing bars to be cut; The alignment section, located on the outside of one of the support sections, is used to align the outer ends of the reinforcing bars to be cut.

[0008] As an optimization, the support base includes a base plate and two support plates, the two support plates are vertically parallel to each other on the base plate, the fixed end of the telescopic cylinder is fixedly connected to the support plates, and the telescopic cylinder is horizontally arranged.

[0009] As an optimization, the length direction of the clamping plate is perpendicular to the axis direction of the telescopic cylinder, and the middle of the upper surface and the middle of the lower surface of the clamping plate are recessed to form a connecting section, with two movable sections located on both sides of the connecting section; The auxiliary wheel is rotatably connected to the middle of the connecting section. The diameter of the auxiliary wheel is greater than the minimum thickness of the movable section and the thickness of the middle of the connecting section, and the diameter of the auxiliary wheel is less than the maximum thickness of the movable section.

[0010] As an optimization, a limiting plate is connected to the upper side of the clamping plate. The limiting plate is located at the end of the clamping plate adjacent to the movable section of the telescopic cylinder. The limiting plate and the clamping plate form an L-shaped limiting interval. The width and height of the limiting interval are both smaller than the diameter of the reinforcing bar to be cut.

[0011] As an optimization, two adjacent reinforcing bars to be cut are staggered vertically between two continuous clamping slots.

[0012] As an optimization, the telescopic assembly includes a telescopic cylinder and two support plates. The two support plates are connected to the upper inner side of the movable section and the lower inner side of the movable section. A strut is rotatably connected between the two connecting ends of the telescopic cylinder and the ends of the support plates. The telescopic cylinder is connected to an oil supply line, and the outer end of the oil supply line is connected to the side of the clamping plate away from the auxiliary wheel.

[0013] As an optimization, the active segment includes an elastic segment connected to the telescopic component and a support segment connecting the two elastic segments, wherein the elastic segment is soft and the support segment is rigid.

[0014] As an optimization, the cutting part includes a cutting support, a lifting telescopic rod, and a cutting saw. The upper end of the lifting telescopic rod is connected to a cutting frame, the cutting saw is connected to the outer end of the cutting frame, and the cutting saw is connected to a cutting motor. The cutting support has an adjustment groove inside, and the lower end of the lifting telescopic rod is slidably connected to the adjustment groove. The adjustment groove has an adjustment screw inside, which is threadedly connected to the lifting telescopic rod. One end of the adjustment screw is connected to an adjustment motor.

[0015] As an optimization, the alignment part includes an alignment support, an alignment telescopic rod, and a push plate. The alignment telescopic rod is connected to the upper part of the alignment support, and the push plate is connected to the extended end of the alignment telescopic rod. The outer side of the push plate is arranged opposite to the outer side of the >-shaped clamping groove.

[0016] This solution provides a steel bar cutting device for building construction, which has the following advantages: This application clamps and supports multiple steel bars to be cut using two support parts, so that the multiple steel bars to be cut are arranged alternately from top to bottom. When the cutting saw cuts downwards, it can cut two adjacent steel bars to be cut at the same time. The cutting length of the cutting saw remains approximately constant, ensuring the stable operation of the cutting saw, avoiding damage to the cutting saw, achieving efficient cutting of multiple steel bars to be cut, and effectively improving the steel bar cutting efficiency. During the cutting process, the steel bar to be cut is efficiently clamped by the clamping plate. After the steel bar is cut, the steel bar to be cut is withdrawn by the auxiliary wheel, which does not affect the stable operation of cutting and feeding. Attached Figure Description

In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figure 1-7 As shown, a rebar cutting device for building construction includes two supporting parts for supporting the rebar 1 to be cut. Each supporting part includes a support base 2 and several telescopic cylinders 3 arranged in a staggered manner. The movable end of each telescopic cylinder 3 is connected to a clamping plate 4. Multiple continuous >-shaped clamping grooves are formed between the clamping plates 4. An auxiliary wheel 5 is connected to the middle of each clamping plate 4. The two sides of the auxiliary wheel 5 are movable sections 11. The movable sections 11 are equipped with telescopic components inside. The telescopic components are used to push the movable sections 11 to clamp the rebar 1 to be cut. The cutting section, located between the two supporting sections, is used to cut the reinforcing bar 1 to be cut; The alignment section, located on the outside of one of the support sections, is used to align the outer end of the steel bar 1 to be cut.

[0027] Multiple reinforcing bars 1 to be cut are clamped by the support structure, fixing them horizontally. The reinforcing bars 1 are staggered downwards, with adjacent bars staggered vertically and horizontally, but not completely offset. This allows the cutting section to cut two reinforcing bars 1 simultaneously, keeping the cutting length within a certain range and ensuring the stability of the cutting process.

[0028] like Figure 1 As shown, the support base 2 includes a base plate and two support plates. The two support plates are vertically parallel to each other on the base plate. The fixed end of the telescopic cylinder 3 is fixedly connected to the support plates. The telescopic cylinder 3 is horizontally arranged.

[0029] like Figure 5 As shown, the length direction of the clamping plate 4 is perpendicular to the axial direction of the telescopic cylinder 3. The middle of the upper surface and the middle of the lower surface of the clamping plate 4 are recessed to form a connecting section 6, and two movable sections 11 are located on both sides of the connecting section 6. The auxiliary wheel 5 is rotatably connected to the middle of the connecting section 6. The diameter of the auxiliary wheel 5 is greater than the minimum thickness of the movable section 11 and the thickness of the middle of the connecting section 6, and the diameter of the auxiliary wheel 5 is less than the maximum thickness of the movable section 11.

[0030] In the initial state, the auxiliary wheel 5 clamps the steel bar 1 to be cut, and the auxiliary wheel 5 can also assist in moving the steel bar 1 to be cut.

[0031] like Figure 4 As shown, a limiting plate is connected to the upper side of the clamping plate 4. The limiting plate is located at the end of the clamping plate 4 adjacent to the movable section 11 of the telescopic cylinder 3. The limiting plate and the clamping plate 4 form an L-shaped limiting interval. The width and height of the limiting interval are both smaller than the diameter of the steel bar 1 to be cut.

[0032] Two adjacent steel bars to be cut are staggered vertically between two continuous clamping slots.

[0033] The limiting plate is used to prevent the steel bar 1 to be cut from coming out. The connecting section 6 can also limit the steel bar 1 to be cut.

[0034] like Figure 5 and Figure 7 As shown, the telescopic assembly includes a telescopic cylinder 7 and two support plates 8. The two support plates 8 are connected to the upper inner side and the lower inner side of the movable section 11. The two connecting ends of the telescopic cylinder 7 are rotatably connected to the ends of the support plates 8. The telescopic cylinder 7 is connected to an oil supply line 10, and the outer end of the oil supply line 10 is connected to the side of the clamping plate 4 away from the auxiliary wheel 5.

[0035] When the telescopic cylinder 7 is supplied with oil, the telescopic cylinder 7 pushes the two clamping plates 4 outward through the support rod 9, so that the clamping plates 4 press against the movable section 11 to clamp the steel bar.

[0036] like Figure 7 As shown, the movable segment 11 includes an elastic segment 12 connected to the telescopic assembly and a support segment 13 connected between the two elastic segments 12. The elastic segment 12 is soft and the support segment 13 is rigid.

[0037] The outer end of the elastic section 12 can tighten the reinforcing bar, such as Figure 4 As shown, the steel bars are clamped at three points by two adjacent clamping plates 4 and the elastic segment 12 of the opposite clamping plate 4 to maintain the stability of the steel bars.

[0038] like Figure 1As shown, the cutting part includes a cutting support 14, a lifting telescopic rod 15, and a cutting saw 16. The upper end of the lifting telescopic rod 15 is connected to a cutting frame, the cutting saw 16 is connected to the outer end of the cutting frame, and the cutting saw 16 is connected to a cutting motor. The cutting support 14 has an adjustment groove inside, and the lower end of the lifting telescopic rod 15 is slidably connected to the adjustment groove. The adjustment groove has an adjustment screw inside, and the adjustment screw is threadedly connected to the lifting telescopic rod 15. One end of the adjustment screw is connected to an adjustment motor.

[0039] The cutting saw 16 can move closer to or further away from the steel bar 1 to be cut along the cutting support 14, and the cutting saw 16 can cut from top to bottom. To ensure the cutting effect, an operating handle can also be connected to the outer casing of the cutting saw 16 to facilitate workers to increase the cutting force of the cutting saw 16.

[0040] like Figure 1 As shown, the alignment part includes an alignment support 17, an alignment telescopic rod 18, and a push plate 19. The alignment telescopic rod 18 is connected to the upper part of the alignment support 17, and the push plate 19 is connected to the extended end of the alignment telescopic rod 18. The outer side of the push plate 19 is arranged opposite to the outer side of the >-shaped clamping groove.

[0041] By aligning the parts and pushing one end of the steel bar 1 to be cut, the cutting accuracy is ensured.

[0042] How to use: In practical use, the two support parts are arranged opposite each other, and the cutting part is located between the two support parts, so that the cutting saw 16 is away from the line connecting the >-shaped clamping grooves in the two support parts; Multiple steel bars 1 to be cut are placed on two support parts, the telescopic cylinder 3 extends, and the multiple steel bars 1 to be cut are clamped by the clamping plate 4. First, oil is supplied to the telescopic cylinder 7 through the oil supply line 10. The telescopic cylinder 7 extends, making the thickness of the movable section 11 smaller than the diameter of the auxiliary roller. The auxiliary roller then performs initial clamping on the steel bar 1 to be cut. The alignment telescopic rod 18 extends and pushes one end of the steel bar 1 to be cut flat through the push plate 19, so that the ends of multiple steel bars 1 to be cut are aligned. The auxiliary wheel 5 improves the relative movement efficiency between the steel bar 1 to be cut and the clamping plate 4. After the cutting steel bar 1 is aligned, the hydraulic oil inside the telescopic cylinder 7 is released, the telescopic cylinder 7 is shortened, and the two support plates 8 are pushed outward by the support rod 9, so that the thickness of the movable section 11 is greater than the diameter of the auxiliary wheel 5, and the steel bar 1 to be cut is clamped by the movable section 11. like Figure 4As shown, in the clamping state, the three points on the outside of the steel bar 1 to be cut are clamped by the movable section 11 of the two adjacent clamping plates 4 and the support section 13 of the opposite clamping plate 4, so as to maintain the stability of the steel bar 1 to be cut, avoid shaking during the cutting process, and prevent the cutting saw 16 from breaking. By adjusting the motor to drive the lifting telescopic rod 15 and the cutting saw 16 to move, the cutting saw 16 is moved to directly above the steel bar 1 to be cut; The lifting telescopic rod 15 gradually shortens, and the cutting motor drives the cutting saw 16 to operate, and the cutting saw 16 cuts the steel bar 1 to be cut. After the cutting saw 16 finishes cutting the upper steel bar 1, the clamping plate 4 holding the steel bar 1 narrows, and the auxiliary wheel 5 drives the cut steel bar to move outward without affecting the continued descent of the cutting saw 16, so that the lower steel bar 1 can continue to be cut.

[0043] Even after the upper clamping plate 4 is retracted, the elastic section 12 of the clamping plate 4 can still support the lower reinforcing bar.

[0044] In the clamped state, the two adjacent steel bars 1 to be cut have a partially overlapping area, so that when the cutting saw 16 is cutting the steel bar to be cut, it has already started cutting the steel bar located on the lower side before it has finished cutting one steel bar 1. That is, the force-bearing width of the cutting saw 16 remains roughly stable, avoiding the problem of uneven force on the cutting saw 16 during the cutting process.

The patent protection scope of the present invention includes, but is not limited to, the product form and style of the above-described specific embodiments.
