Description

Technical Field

[0001] This utility model relates to the technical field of saw blade processing equipment, specifically to a band saw blade tooth splitting device. Background Technology

[0002] Band saw blades are an important component of band saw machines, primarily used for cutting various materials such as wood, metal, and plastic. The design and performance of the band saw blade directly affect the sawing quality and efficiency; toothed saw blades are designed with teeth spaced to opposite sides.

[0003] The teeth on a band saw blade refer to the teeth arranged in a specific pattern on the cutting edge. This design aims to improve sawing efficiency, reduce sawing resistance, and also help remove sawdust, keeping the cut surface clean and smooth. The tooth arrangement on a band saw blade can vary depending on the material and sawing requirements.

[0004] Patent application CN201911038287.6 discloses a band saw blade tooth-splitting mechanism, including a machine base. A sliding seat is fixedly mounted on the machine base from the feed end to the discharge end of the band saw blade. A fixed seat for loading the band saw blade is mounted on the sliding seat. A first linear module for driving the fixed seat to move linearly along the sliding seat is mounted at the bottom of the sliding seat. A left tooth-splitting device and a right tooth-splitting device are respectively mounted on both sides of the sliding seat. Its drawbacks are that it fixes the band saw blade to the fixed seat using a screw, thus only clamping and fixing saw blades of a limited length for tooth splitting during processing. This fixed seat structure is not suitable for longer band saw blades. Secondly, the push pins on the left and right tooth-splitting devices are fixed in position using pressure plates, which is not convenient for precise adjustment.

[0005] In view of the above, it is necessary to propose a band saw blade tooth splitting device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to overcome the defects in the existing technology and provide a band saw blade tooth splitting device.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows: A band saw blade tooth splitting device includes a machine base, on which two tooth splitting slide structures are arranged opposite each other. Between the two tooth splitting slide structures is a straight gap for the band saw blade to move. The sliding parts of the two tooth splitting slide structures move relative to each other. A push tooth structure is provided on the end face of the sliding parts on both sides that are close to each other. The push tooth structure includes a track base and a sliding seat. The sliding part is provided with a groove for positioning and installing the track base. A transverse track is provided on the track base. The sliding seat is provided with a groove that cooperates with the transverse track. It also includes a first fixing bolt for fixing the sliding seat to the track base. A clamping platform is provided on the side of the sliding seat opposite to the groove that extends toward the other side of the sliding part. A push block is provided at the end of the clamping platform.

[0008] Furthermore, the machine base is provided with a mounting seat in parallel. The toothed slide structure includes a guide rail, a slider, and a slide plate. The mounting seat is provided with a guide rail, and the bottom surface of the slide plate is provided with a slider. The slider is slidably mounted on the guide rail. The two toothed slide structures are provided with a pushing mechanism on opposite sides. The output end of the pushing mechanism is connected to the slide plate.

[0009] Furthermore, a clamping plate is provided on one side of the clamping platform, and a gap is formed between the clamping plate and the clamping platform. A second fixing bolt is provided through the clamping plate and screwed onto the clamping platform. The push block is placed in the gap.

[0010] Furthermore, the clamping platform forms a stepped portion on one side of the gap, and the push block is positioned horizontally on the step, with the thickness of the push block being greater than the width of the horizontal surface of the step.

[0011] Furthermore, it also includes a clamping and conveying structure for moving the band saw blade. The clamping and conveying structure is arranged along the length of the I-shaped slit and is respectively arranged at both ends of the I-shaped slit. The bottom of the I-shaped slit is provided with supporting rollers.

[0012] Furthermore, the clamping and conveying structure includes pairs of clamping roller sets, with multiple clamping roller sets respectively provided at the beginning and end of the straight slit.

[0013] Furthermore, the clamping roller assembly includes a fixed roller and a movable roller. The movable roller is pushed toward the fixed roller by a push cylinder, so that the fixed roller and the movable roller clamp the band saw blade.

[0014] Furthermore, the clamping and conveying structure is provided with a tooth feeding device at the entry end of the band saw blade into the tooth splitting device, and a blocking structure is also provided at the entry end. The blocking structure includes a fixed clamping block and a movable clamping block. The movable clamping block is controlled by a push cylinder to move toward the fixed clamping block to clamp the band saw blade.

[0015] The advantages and beneficial effects of this utility model are as follows: This utility model provides a band saw blade tooth-splitting device with an easily adjustable tooth-splitting slide structure. The slide seat can slide laterally relative to the track base to change its position, facilitating the adjustment of the relative positions of the push blocks on both sides of the slide. It can be configured for aligned or staggered settings, and the distance between the push blocks and the tooth-feeding device is easily adjustable, thus making it suitable for band saw blades with different tooth pitches for tooth splitting. This device holds the band saw blade with rollers and is conveyed by the tooth-feeding device, without limiting the length of the band saw blade, making it convenient for processing longer saw blades.

Detailed Implementation

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0021] A band saw blade tooth splitting device, such as Figure 1-3 As shown, the system includes a machine base 1, which serves as the foundation platform for mounting various upper-level components. Two toothed slide structures 2 are positioned opposite each other on the machine base 1. A mounting base 12 is arranged parallel to each other on the machine base 1. Each toothed slide structure 2 includes a guide rail 13, a slider 14, and a sliding plate. The guide rail 13 is located on the mounting base 12, and the slider 14 is located on the bottom surface of the sliding plate. The slider 14 is slidably mounted on the guide rail 13. A pushing mechanism is located on one side of each toothed slide structure 2 away from each other. The output end of the pushing mechanism is connected to the sliding plate. In practical use, the pushing mechanism can be a cylinder, hydraulic cylinder, servo motor, or other drive mechanism (not shown in the figure).

[0022] When the sliding parts 3 on the two sides of the tooth-splitting slide structure 2 slide, they can perform tooth splitting on the saw teeth on the band saw blade that passes through the I-shaped slit. The control method can be that the two sides of the sliding parts 3 move in a mirror image at the same time. When the two sides of the sliding parts 3 move towards the middle, the teeth aligned with the push blocks 11 at their ends are pushed out laterally, forming the saw blade teeth that are laterally bent. Another method is that the two sides of the sliding parts 3 move alternately, in coordination with the tooth feeding device to push the band saw blade, and perform tooth splitting operation on the saw teeth one by one.

[0023] Between the two toothed sliding blocks 2 is a straight slit for the band saw blade to move. The straight slit allows the band saw blade to pass through easily, and when the sliding part 3 pushes the saw teeth, it provides lateral support to the lower part of the band saw blade, so that the sliding part 3 applies the thrust only to the saw teeth, causing the saw teeth to tilt laterally.

[0024] The sliding parts 3 of the two toothed slide blocks 2 move relative to each other. Specifically, the end faces of the two sliding parts 3 that are close to each other are provided with push tooth structures 4, such as... Figure 2 , 3 As shown, the pusher structure 4 includes a track base 5 and a sliding seat 6. By adjusting the track base 5 and the sliding seat 6, this device can be applied to the tooth-splitting operation of band saw blades with different tooth pitches. Specifically, the sliding part 3 is provided with a groove 8 for positioning and installing the track base 5. The track base 5 is provided with a transverse track 7. In actual use, the track base 5 is fixed in the groove 8 with bolts, which is convenient for disassembly and replacement. Since the band saw blades are of different models and have different widths, the processing height of the saw teeth will be different when installed on this tooth-splitting device. Therefore, track bases 5 with different transverse track 7 heights can be replaced for adaptive adjustment.

[0025] The sliding seat 6 is provided with a groove 26 that mates with the transverse track 7, and also includes a first fixing bolt 9 that fixes the sliding seat 6 to the track base 5. Since the spacing between adjacent saw teeth of different models of band saw blades is different, in order to solve this problem, the sliding seat 6 of this device is slidably set on the transverse track 7 through the groove 26, so that the sliding seat 6 can be adjusted laterally within a certain range, so that the lateral spacing of the push blocks 11 on both sides matches the saw tooth spacing. Specifically, the sliding seat 6 is provided with a transverse waist hole 27, through which the first fixing bolt 9 is installed. A screw hole is provided in the middle of the track base 5 to be screwed in. After tightening, the position of the sliding seat 6 can be fixed. The length of the waist hole 27 corresponds to the adjustment range of the sliding seat 6.

[0026] A clamping platform 10 extending towards the sliding part 3 on the opposite side of the sliding seat 6 and the sliding groove 26 is provided, and a push block 11 is provided at the end of the clamping platform 10. The push block 11 is clamped and fixed by the clamping platform 10, which facilitates the replacement of the push block 11 after long-term use. Specifically, the clamping platform 10 forms a step part 17 on one side of the gap, and the push block 11 is positioned horizontally on the step. Since the horizontal position of the step is fixed, the lowest point is fixed when the push block 11 is placed on it, and it can be accurately pushed near the root of the saw teeth. The thickness of the push block 11 is greater than the width of the horizontal plane of the step part 17. A clamping plate 15 is provided on one side of the clamping platform 10, and a gap is formed between the clamping plate 15 and the clamping platform 10. A second fixing bolt 16 is screwed onto the clamping platform 10 through the clamping plate 15, and the push block 11 is placed in the gap. When clamping and fixing the push block 11, the push block 11 is clamped and fixed on the step portion 17 by the clamping plate 15, and then clamped and fixed by the second fixing bolt 16.

[0027] Furthermore, it also includes a clamping and conveying structure for moving the band saw blade. This clamping and conveying structure is arranged along the length of the I-shaped slit and is respectively located at both ends of the I-shaped slit. Support rollers 18 are provided at the bottom of the I-shaped slit. To facilitate tooth splitting of longer band saw blades, the clamping and conveying structures on both sides limit the height of the continuously entering band saw blades, ensuring the bottom of the band saw blade rests on the support rollers 18. Lateral support is also needed to keep the band saw blade upright as it passes through the I-shaped slit. Specifically, the clamping and conveying structure also includes paired clamping roller groups 19, with multiple clamping roller groups 19 located at the beginning and end of the I-shaped slit. The clamping roller groups 19 clamp the band saw blade on both sides with a certain pressure, keeping it upright as it passes through the tooth splitting device.

[0028] Furthermore, the clamping roller assembly 19 includes a fixed roller 20 and a movable roller 21. The movable roller 21 is pushed towards the fixed roller 20 by a push cylinder 25, so that the fixed roller 20 and the movable roller 21 clamp the band saw blade. When installing the band saw blade, the push cylinder 25 on one side retracts simultaneously, causing the movable roller 21 to move away from the fixed roller 20, thereby providing sufficient installation clearance. After the band saw blade is installed, the equipment is started, and the push cylinder 25 pushes the movable roller 21 closer to the fixed roller 20, thereby clamping the band saw blade and keeping it upright.

[0029] The clamping and conveying structure has a tooth feeding device at the entry end of the band saw blade into the tooth splitting device, and a blocking structure 22 at the entry end. The blocking structure 22 includes a fixed clamping block 23 and a movable clamping block 24. The movable clamping block 24 is controlled by a push cylinder 25 to move toward the fixed clamping block 23 to clamp the band saw blade. The movement of the band saw blade in the tooth splitting device is controlled by the tooth feeding device, so that the saw teeth pass through one by one to complete the tooth splitting operation. The movement of the blocking structure 22 is similar to that of the clamping roller assembly 19. The push cylinder 25 controls the movement of the movable clamping block 24 to clamp the saw blade. The cubic clamping block makes contact with the band saw blade through planar friction. Its function is to cooperate with the tooth feeding device to prevent the band saw blade from moving excessively or moving in the opposite direction.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
