Description

Technical Field

[0001] This utility model belongs to the field of cement culvert processing technology, and in particular relates to a saw blade tightening structure for a steel bar sawing machine. Background Technology

[0002] During the processing of cement culverts, steel bars need to be pre-tied into cages, which are then placed into molds. Concrete is then poured into the molds. The steel cages effectively ensure the rigidity and structural stability of the cement culvert structure. Since the required length of the steel bars varies during actual processing, a steel bar saw is needed to cut the steel bars to the required length.

[0003] Some steel bar saw blades are fixed with bolts during installation, and the lack of a tension structure on both sides of the blade results in insufficient blade tension. Therefore, a saw blade tightening structure for steel bar saws is needed, which can fix and pull both sides of the saw blade separately, so that the saw blade is always under tension, thereby meeting the tension requirements of the saw blade during steel bar cutting. Utility Model Content

[0004] The purpose of this utility model is to provide a saw blade tightening structure for a rebar sawing machine, which fixes and pulls both sides of the saw blade to keep the saw blade in a taut state at all times, thereby meeting the tension requirements of the saw blade during the cutting of rebar and solving the technical problems mentioned in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A saw blade tightening structure for a rebar sawing machine includes a frame: two shells are provided at the bottom of the frame, bolt rods are threadedly connected to the surface of the shells, and a saw blade is provided in the inner cavity of the two shells. A vertical plate is welded to the bottom of the frame, and an electric telescopic rod and a slide rail are fixedly installed on the surface of the vertical plate by bolts. A slider is slidably connected to the surface of the slide rail. A slide plate is fixedly connected to the output end of the electric telescopic rod by a flange. A dial is provided on the surface of the slider. A connecting rod is welded between the slider and the shell located on the right side. A saw table is installed below the frame.

[0006] Preferably, the end of the bolt rod passes through the saw blade and abuts against the inner wall of the housing, and is fixedly connected between the housing and the frame on the left side.

[0007] Preferably, the front end of the deflector extends into the inner cavity of the slide plate, the rear end of the deflector is rotatably connected to the slider, and the surface of the deflector is in contact with the inner wall of the slide plate.

[0008] Preferably, the surface of the vertical plate is fixedly mounted with two symmetrically arranged clamping blocks by bolts, and the clamping blocks are slidably connected to the sliding plate.

[0009] Preferably, a locking block and a locking rail are fixedly connected to the top of the housing and the bottom of the frame on the right side, respectively, and the locking rail and the locking block are slidably connected.

[0010] Preferably, a steel bar limiting plate is fixedly installed on the top of the saw table.

[0011] The beneficial effects of this utility model are:

[0012] This invention uses the cooperation of the housing and bolt rod on the left side to fix one side of the saw blade. At the same time, the sliding of the slider on the slide rail surface drives the connecting rod to move. Then, the connecting rod, through the cooperation of the housing and bolt rod on the right side, drives the saw blade to tighten. This achieves the fixation and tension of both sides of the saw blade of the sawing machine, so that the saw blade is always in a taut state, thereby meeting the tension requirements of the saw blade during the cutting of steel bars.

[0013] 2. This utility model reduces the friction between the slide and the dial shaft by rotating the dial shaft, thus avoiding the situation where the lifespan of the two is reduced due to excessive wear.

[0014] 3. This utility model limits the movement of the skateboard by setting the clamping block, which prevents the skateboard from shaking during movement and thus ensures the stability of the skateboard during movement.

[0015] 4. This utility model uses the cooperation of the rail and the block to limit the movement of the housing on the right side, ensuring the stability of the housing during movement.

[0016] 5. This utility model limits the position of the steel bars placed on the top of the saw table by setting the steel bar limiting plate, thus ensuring the stability of the steel bars' position during the cutting process. Attached Figure Description

[0024] In the following description, embodiments of the saw blade tightening structure for the steel bar sawing machine of the present invention will be described with reference to the accompanying drawings. Example 1

[0025] Figure 1-4 This invention illustrates a saw blade tightening structure for a rebar sawing machine according to an embodiment of the present invention. It includes a frame 1: two housings 2 are disposed at the bottom of the frame 1, with bolt rods 3 threadedly connected to the surface of each housing 2. A saw blade 4 is disposed within the inner cavity of both housings 2. The end of the bolt rod 3 penetrates the saw blade 4 and abuts against the inner wall of the housing 2. The housing 2 on the left side is fixedly connected to the frame 1. A vertical plate 5 is welded to the bottom of the frame 1. An electric telescopic rod 6 and a slide rail 7 are fixedly mounted on the surface of the vertical plate 5 by bolts. A slider 8 is slidably connected to the surface of the slide rail 7. A slide plate 9 is fixedly connected to the output end of the electric telescopic rod 6 via a flange. A pivot 10 is disposed on the surface of the slider 8, with the front end of the pivot 10 extending into the inner cavity of the slide plate 9. The rear end of 10 is rotatably connected to the slider 8. The surface of the pivot 10 is in contact with the inner wall of the slide plate 9. By rotating the pivot 10, the friction of the slide plate 9 moving the pivot 10 is reduced, avoiding the situation where the lifespan of the two is reduced due to excessive wear. Two symmetrically arranged clamping blocks 11 are fixedly installed on the surface of the vertical plate 5 by bolts. The clamping blocks 11 are slidably connected to the slide plate 9. By setting the clamping blocks 11, the movement of the slide plate 9 is limited, avoiding the situation where the slide plate 9 shakes during movement, thereby ensuring the stability of the slide plate 9 during movement. The slider 8 and the shell 2 located on the right side are welded together with a connecting rod 12. A saw table 15 is installed under the frame 1. Example 2

[0026] Figure 1-4This invention illustrates a saw blade tightening structure for a rebar sawing machine according to an embodiment of the present invention. The structure includes a frame 1. Two housings 2 are located at the bottom of the frame 1. Bolt rods 3 are threaded onto the surface of each housing 2. A saw blade 4 is housed within the inner cavity of both housings 2. A vertical plate 5 is welded to the bottom of the frame 1. An electric telescopic rod 6 and a slide rail 7 are bolted to the surface of the vertical plate 5. A slider 8 is slidably connected to the surface of the slide rail 7. A sliding plate 9 is fixedly connected to the output end of the electric telescopic rod 6 via a flange. A pivot shaft 10 is located on the surface of the slider 8. A connecting rod is welded between the slider 8 and the housing 2 located on the right side. The connecting rod 12 is fixedly connected to the top of the shell 2 on the right side and the bottom of the frame 1 with a locking block 14 and a locking rail 13 respectively. The locking rail 13 and the locking block 14 are slidably connected. Through the cooperation of the locking rail 13 and the locking block 14, the movement of the shell 2 on the right side is limited, ensuring the stability of the shell 2 during movement. A saw table 15 is installed under the frame 1. A steel bar limiting plate 16 is fixedly installed on the top of the saw table 15. The steel bar limiting plate 16 limits the steel bar placed on the top of the saw table 15, ensuring the stability of the steel bar's position during the cutting process.

[0027] Working principle: When using this utility model, the user fixes the saw blade 4 to the inner cavity of the housing 2 using the bolt rod 3. At this time, the housing 2 on the left side fixes one side of the saw blade 4. Then, the electric telescopic rod 6 is turned on to drive the slide plate 9 to move vertically, so that the slide plate 9 drives the slider 8 to slide on the surface of the slide rail 7 through the pivot shaft 10. Then, the slider 8 drives the housing 2 on the right side to move through the connecting rod 12. Then, the cooperation between the housing 2 on the right side and the bolt rod 3 drives the saw blade 4 to tighten. Then, the frame 1 drives the housing 2 to cut the steel bar placed in the steel bar limiting plate 16. This realizes the fixing and pulling of both sides of the saw blade of the saw machine, so that the saw blade is always in a taut state, thereby meeting the tension requirements of the saw blade during the process of cutting steel bars.

[0028] In summary, the saw blade tightening structure of this rebar sawing machine uses the cooperation of the housing 2 on the left side and the bolt rod 3 to fix one side of the saw blade 4. At the same time, the sliding of the slider 8 on the surface of the slide rail 7 drives the connecting rod 12 to move. Then, the connecting rod 12, through the cooperation of the housing 2 on the right side and the bolt rod 3, drives the saw blade 4 to tighten. This achieves the fixation and tension of both sides of the saw blade of the sawing machine, so that the saw blade is always in a taut state, thereby meeting the tension requirements of the saw blade during the cutting of rebar.
