Description

Technical Field

[0001] This utility model relates to the field of sawing technology, specifically to a guide device for saw blades. Background Technology

[0002] A band saw is a machine tool used for sawing metal materials. It is mainly divided into two categories: circular band saws and band saws. The saw blade is a cutting tool used for cutting metal. It is usually composed of circular saw blades, saw bands, or saw blades. These saw blades are used to cut round metal, square metal, pipes, and profiles.

[0003] The guiding mechanism is a component that ensures the cutting accuracy and stability of the saw blade. It generally consists of two alloy blades and a pulley driven by a bearing at the lower end of the alloy blades. A long, narrow slit slightly wider than the thickness of the saw blade is formed between the alloy blades to guide the saw blade, allowing it to move on the pulley and ensuring that it remains linear and stable during the cutting process.

[0004] Therefore, the following shortcomings exist during use: the reciprocating motion of the saw blade will wear down the alloy blade and pulley, and it is easy to cause local overheating. After long-term use, it is easy to cause the guiding effect on the saw blade to fail, resulting in saw blade oscillation and affecting sawing accuracy. Utility Model Content

[0005] I. Technical problems to be solved

[0006] The technical problem this invention aims to solve is that the guiding device is prone to wear and heat generation, which causes the guiding function to fail, resulting in saw blade oscillation and skewed sawing.

[0007] II. Technical Solution

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a guiding device for a saw blade of a sawing machine, including a guide member, wherein a connecting rod is provided at the lower end of the guide member;

[0009] The guide member is provided with a groove on its upper part, the groove is connected to the front and back, the bottom inner wall of the groove is provided with a through groove, and a tungsten steel wheel is rotatably provided in the through groove;

[0010] The guide member is provided with left and right opposite sliding grooves above it. The sliding grooves are inclined and one end is connected to the groove, while the other end extends out of the guide member. A guide block is slidably provided in the sliding groove. A limit screw is inserted into the upper end of the guide block. The saw blade is located in the groove. The adjacent ends of the two guide blocks are in contact with the saw blade to limit the saw blade.

[0011] As an improvement, the guide member has notches on its left and right side walls that communicate with the through groove and extend out of the guide member at their lower ends. A horizontal rod is provided between the notches, and the tungsten steel wheel is rotatably sleeved on the horizontal rod through a bearing.

[0012] As an improvement, the notch has recesses on its front and rear inner walls, and slots on the inner walls of the recesses. A limiting block that fits into the notch and is in contact with the horizontal bar is inserted into the notch. The front and rear ends of the limiting block are inserted into the recesses, and rubber blocks that fit into the slots are provided on the front and rear side walls.

[0013] As an improvement, the inner walls of the groove and the recess are connected at a 45° angle.

[0014] As an improvement, a rectangular extension plate is provided at one end of each of the two guide blocks, and the extension plate is made of tungsten steel.

[0015] As an improvement, the upper end of the guide block is provided with an inclined strip groove parallel to the center line of the slide groove, and the guide member below the strip groove is provided with an internal thread blind hole. The limiting screw passes through the strip groove and is threaded into the internal thread blind hole, and is in contact with the guide block.

[0016] III. Beneficial Effects

[0017] The advantages of this utility model compared with the prior art are as follows:

[0018] This invention effectively solves the technical problems of easy wear and poor heat dissipation in traditional guide devices through the matching tungsten steel wheel structure and adjustable guide block design, resulting in a longer guide life and enabling the saw blade to be limited and guided by the guide device, avoiding saw blade oscillation and ensuring sawing accuracy.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] As attached Figure 1-5 As shown, the guide device for the saw blade of the sawing machine includes a guide component 1. The guide component 1 is integrally cast from high-strength alloy steel. The lower end of the guide component 1 is provided with a connecting rod 2. The guide component 1 can be fixedly installed on the sawing machine at the required position through the connecting rod 2 to guide the saw blade.

[0028] The guide member 1 has a groove 3 on its upper part, the groove 3 is connected front and back, and the bottom inner wall of the groove 3 has a through groove 4 in the middle. A tungsten steel wheel 5 is rotatably installed in the through groove 4. The tungsten steel wheel 5 is more durable. The left and right side walls of the guide member 1 have notches 8 that are connected to the through groove 4 and extend out of the guide member 1 at their lower ends. A horizontal rod 9 is provided between the notches 8. The tungsten steel wheel 5 is rotatably sleeved on the horizontal rod 9 through a bearing. The horizontal rod 9 and the bearing cooperate to achieve low friction rotation and reduce the problem of local overheating.

[0029] Furthermore, the notch 8 has recesses 10 on its front and rear inner walls, and slots 11 on the inner walls of the recesses 10. A limiting block 12 that is in contact with the horizontal rod 9 is inserted into the notch 8. The front and rear ends of the limiting block 12 are inserted into the recesses 10, and rubber blocks 13 are provided on the front and rear side walls that are inserted into the slots 11. The limiting block 12 can be inserted into the notch 8, and the rubber blocks 13 can be inserted into the slots 11 to achieve connection. It is also easy to disassemble and replace the tungsten carbide wheel 5.

[0030] The guide member 1 has two opposing sliding grooves 6 on its upper part. The sliding grooves 6 are inclined, with one end communicating with the groove 3 and the other end extending out of the guide member 1. The inner walls of the sliding grooves 6 and the groove 3 form a 45° angle. Guide blocks 7 are slidably installed in the sliding grooves 6, allowing the guide blocks 7 to slide in the 45° direction within the sliding grooves 6. One adjacent end of the two guide blocks 7 has a rectangular extension plate made of tungsten steel, which is more wear-resistant and durable. A limit screw 16 is inserted into the upper end of each guide block 7. The upper end of each guide block 7 has an inclined strip groove 14 parallel to the center line of the sliding groove 6. The guide member 1 is located below the strip groove 14. The upper part is provided with an internally threaded blind hole 15. The limiting screw 16 passes through the strip groove 14 and is threaded into the internally threaded blind hole 15, and is in contact with the guide block 7. The guide block 7 can be finely adjusted through the strip groove 14 and the limiting screw 16. Loosening the limiting screw 16 can adjust the position of the guide block 7, and tightening the limiting screw 16 can fix the position of the guide block 7. The saw blade passes through the groove 3 and its lower end is slidably connected to the tungsten carbide wheel 5. The extension plate at the adjacent end of the two guide blocks 7 is in contact with the saw blade to limit the saw blade. After the extension plate is worn, the position of the guide block 7 can be adjusted for continued use, so that the saw blade can always be limited and guided by the guiding device, avoiding saw blade swing and ensuring sawing accuracy.
