Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a steel bar cutting device for building construction. Background Technology

[0002] During construction, steel bars, as a crucial building material, often require precise length adjustments based on actual project needs. However, during procurement or prefabrication, various factors may cause some steel bars to exceed the specific requirements of the construction site. In such cases, to ensure project quality and safety while avoiding material waste, specialized cutting equipment is needed to handle these excessively long steel bars.

[0003] In the prior art, Chinese utility model publication CN220127493U discloses a steel bar cutting device for building construction, including a fixing structure and a cutting structure. The cutting structure is disposed on the outer surface of the fixing structure. The fixing structure includes a support unit and a functional unit. The functional unit is formed on the surface of the support unit. The cutting structure includes a motor unit, a cutting unit, and a chipping unit. The motor unit is fixedly connected to the outer surface of the support unit. The cutting unit is threadedly connected to the outer surface of the motor unit. The chipping unit is disposed on the outer surface of the support unit. The support unit includes a support rod, a bearing plate, and a top plate.

[0004] In existing technology, the aforementioned device uses a debris baffle to shield the cutting debris, and a debris box to hold the falling debris, preventing it from flying everywhere and causing burns to the user during rebar cutting. However, some shortcomings still exist in actual use. The debris baffle used for protection is not completely sealed; it has an opening at the top, and the openings on both sides for accommodating the rebar do not completely fit against it. This results in poor actual protective effectiveness, posing a risk of sparks and debris flying out through the gaps between the top and side openings and the rebar during cutting. This creates safety hazards for the surrounding environment and operators, and also affects the cleanliness and tidiness of the work area. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing devices used for protection have a debris baffle that is not completely closed, with an opening at the top and openings on both sides for accommodating the reinforcing bars that cannot be completely fitted with the reinforcing bars, resulting in poor actual protection and the risk of sparks and debris splashing out through the gaps between the top and side openings and the reinforcing bars during cutting. Therefore, this invention proposes a steel bar cutting device for construction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a steel bar cutting device for building construction, comprising a base, a bracket fixedly installed on one side of the upper end of the base, a cylinder fixedly installed in the middle of the upper end of the bracket, a pressure plate fixedly installed at the output end of the cylinder, a fixing rod fixedly installed in the middle of the pressure plate, a cutting blade fixedly installed at one end of the fixing rod, connecting pipes fixedly connected to both ends of the middle of the pressure plate, a sliding groove opened on the outer side of the middle of the lower end of the pressure plate, a plurality of springs evenly fixedly installed in the middle of the sliding groove, a lower pressing block fixedly connected to the lower end of each of the plurality of springs, one end of the lower pressing block slidably engaging with the middle of the sliding groove, and the plurality of lower pressing blocks being close to each other.

[0007] Preferably, a fixing groove is provided in the middle of the upper end of the base, and multiple rotating rods are evenly fixedly installed at one end of the middle of the fixing groove, and the bracket is located above the other end of the fixing groove.

[0008] Preferably, movable grooves are provided on both sides of the middle of the other end of the fixed groove, and a clamp is fixedly installed in the middle of one of the movable grooves.

[0009] Preferably, a bidirectional lead screw is rotatably mounted in the middle of one of the movable slots, and a clamping plate is slidably engaged in the middle of both movable slots.

[0010] Preferably, the lower part of one side of the middle of the two clamping plates is slidably engaged with the slide rod, and the lower part of the other side of the middle of the two clamping plates is threadedly connected with the bidirectional lead screw.

[0011] Preferably, one end of the bidirectional lead screw is fixedly connected to a handle, which is located between the middle of the other movable slot.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, when in use, the steel bar to be cut is placed in the middle of the fixing groove, and the steel bar is clamped and fixed by the clamps on both sides. Then, the cylinder is started by the external equipment to drive the pressure plate to move down. The lower pressure block under the pressure plate is an independent unit. When it comes into contact with the steel bar during the pressing process, the spring will deform and drive the lower pressure block to expand and contract along the sliding groove, so that it fits more closely with the surface of the steel bar, and a more sealed space is formed inside the pressure plate. Then, the steel bar below is cut by the cutting blade. By setting a semi-enclosed pressure plate and a lower pressure block that can fit more closely with the surface of the steel bar, and with the connecting pipe connected to the external exhaust fan, the protective effect of the device is better and the safety hazards are greatly reduced.

[0014] 2. In this utility model, by setting two sets of clamping plates with adjustable clamping distance at one end of the fixed groove, the effective clamping distance can be adjusted by rotating the bidirectional screw through the handle, thereby causing the two clamping plates to move closer or further apart. Combined with the height-adjustable pressure plate above, the device has higher practicality.

[0015] 3. In this utility model, by setting multiple rotating rods at the other end of the fixed groove, the rotating rods make it easier for the operator to move the position of the steel bar on the base, which can effectively save physical strength when loading the steel bar.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as Figure 1-5 As shown, this utility model provides a steel bar cutting device for building construction, including a base 1. A bracket 11 is fixedly installed on one side of the upper end of the base 1. A cylinder 12 is fixedly installed in the middle of the upper end of the bracket 11. A pressure plate 13 is fixedly installed at the output end of the cylinder 12. A fixing rod 15 is fixedly installed in the middle of the pressure plate 13. A cutting blade 16 is fixedly installed at one end of the fixing rod 15. A connecting pipe 14 is fixedly connected to both ends of the middle of the pressure plate 13. A sliding groove 17 is opened on the outer side of the middle of the lower end of the pressure plate 13. Multiple springs 18 are evenly fixedly installed in the middle of the sliding groove 17. The lower ends of the multiple springs 18 are all fixedly connected to a lower pressing block 19. One end of the lower pressing block 19 is slidably engaged with the middle of the sliding groove 17. The multiple lower pressing blocks 19 are close to each other.

[0025] The specific settings and functions of this embodiment are described below. In use, the steel bar to be cut is placed in the middle of the fixing groove 2, and the steel bar is clamped and fixed by the clamping plates 25 on both sides. Then, the cylinder 12 is started by the external device to drive the pressure plate 13 to move down. The lower pressure block 19 below the pressure plate 13 is an independent unit. When it comes into contact with the steel bar during the pressing process, the spring 18 will deform and drive the lower pressure block 19 to expand and contract along the sliding groove 17, so that it fits more closely with the surface of the steel bar, and a more sealed space is formed inside the pressure plate 13. The cutting blade 16 is started to cut the steel bar below. By setting a semi-enclosed pressure plate 13 and a lower pressure block 19 that can fit more closely with the surface of the steel bar, and with the connecting pipe 14 connected to the external exhaust fan, the debris and sparks generated by cutting the steel bar can be intercepted and cleaned, reducing safety hazards.

[0026] Example 2, as Figure 1 , Figure 2 and Figure 3 As shown, a fixed groove 2 is provided in the middle of the upper end of the base 1. Multiple rotating rods 21 are evenly fixedly installed at one end of the middle of the fixed groove 2. The bracket 11 is located above the other end of the fixed groove 2. Movable grooves 22 are provided on both sides of the middle of the other end of the fixed groove 2. A clamping plate 25 is fixedly installed in the middle of one of the movable grooves 22. A bidirectional screw rod 23 is rotatably installed in the middle of the other movable groove 22. The clamping plates 25 are slidably engaged in the middle of both movable grooves 22. The lower part of one side of the middle of the two clamping plates 25 is slidably engaged with the sliding rod 24. The lower part of the other side of the middle of the two clamping plates 25 is threadedly connected to the bidirectional screw rod 23. A handle 26 is fixedly connected to one end of the bidirectional screw rod 23. The handle 26 is located in the middle of the other movable groove 22.

[0027] The overall effect of this embodiment is that, during use, the rebar to be cut is placed at one end of the fixing groove 2 equipped with the rotating rod 21. The rotating rod 21 makes it easier for the operator to move the rebar. When the operator moves the rebar to the other end of the fixing groove 2, the double-acting screw 23 is rotated by the handle 26, which in turn causes the two clamping plates 25 to come closer together until the rebar is clamped and fixed. By setting two sets of clamping plates 25 with adjustable clamping distance at one end of the fixing groove 2, combined with the height-adjustable pressure plate 13 above, the device has greater applicability and can fix and cut rebars of different diameters. Subsequently, it can be connected to external equipment. The cylinder 12 is activated to move the pressure plate 13 downward. The lower pressure block 19 below the pressure plate 13 is an independent unit. When it comes into contact with the steel bar during the downward pressing process, the spring 18 will deform and drive the lower pressure block 19 to extend and retract along the sliding groove 17, so that it fits more closely with the surface of the steel bar and forms a more sealed space inside the pressure plate 13. The cutting blade 16 is activated to cut the steel bar below. By setting a semi-enclosed pressure plate 13 and a lower pressure block 19 that can fit more closely with the surface of the steel bar, and with the connecting pipe 14 connected to the external exhaust fan, the debris and sparks generated by cutting the steel bar can be intercepted and cleaned up, reducing safety hazards.

[0028] The device is used as follows: When in use, place the steel bar to be cut at one end of the fixed groove 2 equipped with the rotating rod 21. The rotating rod 21 makes it easier for the operator to move the steel bar. When the operator moves the steel bar to the other end of the fixed groove 2, the handle 26 drives the bidirectional lead screw 23 to rotate, thereby causing the two clamping plates 25 to come closer together until the steel bar is clamped and fixed. Then, the external equipment starts the cylinder 12 to move the pressure plate 13 downwards. The lower pressure block 19 below the pressure plate 13 is an independent unit. During the downward pressing process, when it comes into contact with the steel bar, the spring 18 will deform and drive the lower pressure block 19 to extend and retract along the sliding groove 17, making it fit more closely to the surface of the steel bar, creating a more sealed space inside the pressure plate 13. The cutting blade 16 is then activated to cut the steel bar below. By setting a semi-enclosed pressure plate 13 and a lower pressure block 19 that fits more closely to the surface of the steel bar, and with the connecting pipe 14 connected to an external exhaust fan, debris and sparks generated during steel bar cutting can be intercepted and cleaned, reducing safety hazards.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
