Bimetal band saw blade with anti-impact function

Abstract

The utility model relates to the technical field of saw blades, and discloses a bimetal band saw blade with an anti-impact function, which comprises a saw blade body, two connecting plates are fixedly mounted on two sides of the saw blade body, hollow columns are movably sleeved on the inner surfaces of the two connecting plates, and the saw blade body is provided with a mounting mechanism. According to the bimetal band saw blade with the anti-impact function, when a worker repeatedly pulls the saw blade body, the saw blade body is discharged out of the surface of a workpiece through the V-shaped chip removal groove, and therefore the phenomenon that when the worker uses the saw blade body for machining, the saw blade body is damaged is avoided. When cutting waste residues are accumulated on the surface of a workpiece, the wave-shaped grooves can effectively improve the toughness of the saw blade body and enable the saw blade body to bend and stretch by a certain angle, so that when a worker saws the cavity workpiece and changes the sawing angle in the cavity workpiece, the brittle failure situation is not prone to occurring, and the impact resistance of the saw blade body is improved.

Description

Technical Field

[0001] This utility model relates to the field of saw blade technology, specifically a bimetallic band saw blade with impact resistance. Background Technology

[0002] Bimetal band saw blades mainly refer to metal cutting band saw blades with high-speed steel or other high-performance steel teeth and low-alloy spring steel saw blades. These saw blades have a wide range of applications and can be used with any type of band saw. They are suitable for continuous sawing of almost all types of metals, such as structural steel, weathering steel, alloy steel, bearing steel, stainless steel, heat-resistant steel, aluminum alloy, and mold steel.

[0003] However, existing bimetal band saw blades lack a chip removal groove, failing to remove waste chips from the workpiece surface and preventing the accumulation of cutting debris, thus affecting work efficiency. They also lack a self-locking device, failing to provide axial fixation during installation and preventing the blade from slipping off the connecting shaft. Furthermore, the absence of a corrugated groove prevents effective stress dissipation and stress accumulation on the back of the blade, leading to breakage at a single point. Additionally, brittle fracture is prone to occur when the sawing angle is changed. Therefore, a bimetal band saw blade with impact resistance is proposed. Summary of the Invention

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a bimetal band saw blade with impact resistance, which has the following beneficial effects:

[0020] 1. This impact-resistant bimetal band saw blade allows the chip removal grooves to expel chips from the workpiece surface when the operator repeatedly pulls the blade body. This prevents the accumulation of cutting waste on the workpiece surface during processing. The corrugated grooves effectively increase the toughness of the saw blade body, allowing it to bend and stretch at a certain angle. This makes it less prone to brittle breakage when the operator changes the sawing angle internally while sawing into a hole, thus improving the impact resistance of the saw blade body.

[0021] 2. This impact-resistant bimetal band saw blade uses a snap-fit ​​mechanism to fix the blade axially during installation, clamping and locking the connection point to prevent the blade from slipping off the connecting shaft, thereby improving the stability of the connected blade.

[0027] 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.

[0028] Please see Figure 1-4 This utility model provides a new technical solution: a bimetal band saw blade with impact resistance, including a saw blade body 1, two connecting plates 7 are fixedly installed on both sides of the saw blade body 1, and hollow columns 8 are movably sleeved on the inner surfaces of the two connecting plates 7.

[0029] The saw blade body 1 is equipped with an installation mechanism, which includes an installation plate 2, a first saw tooth 3, a second saw tooth 4, a V-shaped chip removal groove 5, a wave groove 6, two sliding grooves 9, four springs 10, four moving plates 11, two collars 12, four round holes 13, four round balls 14, two connecting shafts 15, and four locking holes 16.

[0030] Furthermore, the first saw tooth 3 is fixedly installed on the lower surface of the saw blade body 1, and the second saw tooth 4 is fixedly installed on the lower surface of the saw blade body 1;

[0031] Among them, the V-shaped chip removal groove 5 is opened on the lower surface of the saw blade body 1;

[0032] The wave groove 6 is formed on the upper surface of the saw blade body 1.

[0033] Furthermore, two slide grooves 9 are respectively opened on the outer surface of the two connecting plates 7, and four springs 10 are respectively fixedly installed in the inner wall of the two slide grooves 9;

[0034] The four movable plates 11 are fixedly installed on the right ends of the four springs 10, and the opposite surfaces of the four movable plates 11 are all set at an angle.

[0035] Furthermore, two collars 12 are fixedly installed on the outer surfaces of the four movable plates 11, and the two collars 12 are slidably connected to the two sliding grooves 9 respectively.

[0036] Furthermore, four round holes 13 are respectively opened in the inner walls of the two sliding grooves 9, and four round beads 14 are respectively set on the inner surface of the four round holes 13.

[0037] Furthermore, two mounting plates 2 are respectively set on both sides of the saw blade body 1, and two connecting shafts 15 are respectively fixedly installed on the front surface of the two mounting plates 2;

[0038] Among them, four slots 16 are respectively opened on the outer surface of the two connecting shafts 15;

[0039] When using this impact-resistant bimetal band saw blade, a leftward thrust is applied to the collar 12 on the hollow column 8, causing it to move to the left. Simultaneously, the collar 12 drives two movable plates 11 fixedly mounted on the inner surface to move to the left. At this time, the two movable plates 11 apply pressure to the two springs 10 fixedly mounted on the left surface, causing them to contract. The two movable plates 11 no longer obstruct the two round holes 13, i.e., they no longer limit the movement of the two round beads 14 inside the two round holes 13. At this point, the connecting rods fixedly mounted on the right surface of the mounting plate 2... The connecting shaft 15 is inserted into the inner surface of the hollow column 8, and the two locking holes 16 on the outer surface of the connecting shaft 15 are aligned with the two round holes 13 on the hollow column 8. At this time, no upward thrust is applied to the collar 12, and the two springs 10 are no longer under force. At this time, the two springs 10 apply a downward thrust to the two movable plates 11 fixed at the lower end, causing them to strike the two round balls 14, causing the two round balls 14 to move towards the opposite side and engage with the two locking holes 16 on the outer surface of the connecting shaft 15 for fixation. At this time, the installation of the saw blade body 1 is completed. When the operator uses the saw blade body 1 to process the surface of the workpiece, the cutting waste on the workpiece surface will enter the V-shaped chip removal groove 5 opened at the bottom of the saw blade body 1. When the operator repeatedly pulls the saw blade body 1, it will be discharged from the surface of the workpiece through the V-shaped chip removal groove 5. This can avoid the situation where cutting waste accumulates on the surface of the workpiece when the operator uses the saw blade body 1, which requires the operator to clean the waste regularly and thus affect work efficiency. In addition, the double row of saw blades set at the bottom of the saw blade body 1 helps to gather the iron filings on both sides into the V-shaped chip removal groove 5 when working. The back of the saw blade body 1 is provided with a large area of ​​arc-shaped wave grooves 6. The wave grooves 6 can effectively dissipate the stress on the saw blade body 1 during the working process, preventing stress accumulation on the back of the saw blade body 1 and thus preventing breakage at a single point. The wave grooves 6 can also effectively increase the toughness of the saw blade body 1, allowing the saw blade body 1 to bend and stretch at a certain angle. This makes it less likely to break when the operator changes the sawing angle inside the workpiece when sawing holes, thus improving the impact resistance of the saw blade body 1.

[0040] This impact-resistant bimetal band saw blade allows the saw blade body 1 to be repeatedly pulled by the operator, with the chips discharged from the workpiece surface through the V-shaped chip removal groove 5. This prevents the accumulation of cutting waste on the workpiece surface during processing. The wave-shaped groove 6 effectively increases the toughness of the saw blade body 1, allowing it to bend and stretch at a certain angle. This reduces the risk of brittle breakage when changing the sawing angle internally while sawing into a hole, thus improving the impact resistance of the saw blade body 1. Furthermore, this impact-resistant bimetal band saw blade uses a snap-fit ​​mechanism to fix the saw blade axially during installation, clamping and locking the connection point to prevent the saw blade from slipping off the connecting shaft, thereby improving the stability of the connected saw blade.

[0041] Working principle: When using this impact-resistant bimetal band saw blade, a leftward pushing force is applied to the collar 12 on the hollow column 8, causing it to move to the left. Simultaneously, the collar 12 drives two movable plates 11 fixedly mounted on the inner surface to move to the left. At this time, the two movable plates 11 apply pressure to the two springs 10 fixedly mounted on the left surface, causing them to contract. At this point, the two movable plates 11 no longer obstruct the two round holes 13, i.e., they no longer limit the movement of the two round beads 14 inside the two round holes 13. Then, by fixing the right surface of the mounting plate 2... The connecting shaft 15 is inserted into the inner surface of the hollow column 8, and the two locking holes 16 on the outer surface of the connecting shaft 15 are aligned with the two round holes 13 on the hollow column 8. At this time, no upward thrust is applied to the collar 12, and the two springs 10 are no longer under force. The two springs 10 then apply a downward thrust to the two movable plates 11 fixed at the lower end, causing them to strike the two round balls 14. This causes the two round balls 14 to move towards their opposite sides and engage with the two locking holes 16 on the outer surface of the connecting shaft 15 for fixation. At this point, the installation of the saw blade body 1 is complete. When the operator uses the saw blade body 1 to process the surface of the workpiece, the cutting waste on the workpiece surface will enter the V-shaped chip removal groove 5 opened at the bottom of the saw blade body 1. When the operator repeatedly pulls the saw blade body 1, it will be discharged from the surface of the workpiece through the V-shaped chip removal groove 5. This can avoid the accumulation of cutting waste on the surface of the workpiece when the operator uses the saw blade body 1, which requires the operator to clean the waste regularly and thus affect work efficiency. In addition, the double row of saw blades set at the bottom of the saw blade body 1 helps to gather the iron filings on both sides into the V-shaped chip removal groove 5 when working. The back of the saw blade body 1 is provided with a large area of ​​arc-shaped wave grooves 6. The wave grooves 6 can effectively dissipate the stress on the saw blade body 1 during operation, preventing stress accumulation on the back of the saw blade body 1 and thus preventing breakage at a single point. The wave grooves 6 can also effectively increase the toughness of the saw blade body 1, allowing the saw blade body 1 to bend and stretch at a certain angle. This makes it less likely to break when the operator changes the sawing angle inside the workpiece when sawing holes, thus improving the impact resistance of the saw blade body 1.
