Description

Technical Field

[0001] This utility model belongs to the field of sawing technology and relates to a special sawing machine for bevel cutting. Background Technology

[0002] A band saw, as a type of sawing machine, uses a ring-shaped saw blade tensioned on two saw wheels, which drive the blade to cut the workpiece. In existing band saws, the saw blade's cutting surface is perpendicular to the workpiece. However, based on the results of manual sawing, tilting the saw blade significantly improves cutting efficiency at both the front and rear ends, and greatly enhances the stability of the entire material cut. Therefore, it is necessary to design a band saw similar to a manual saw, with the saw blade tilted as in manual cutting, to improve cutting efficiency and stability.

[0003] The device used to clamp workpieces on a sawing machine generally includes a stop block and a clamping cylinder. The clamping cylinder pushes the workpiece to press against the stop block. Existing stops are parallel to the saw blade, resulting in parallel cut surfaces. To cut inclined surfaces, specially machined stop blocks with beveled surfaces are required, and the clamping cylinder must also be positioned at an angle. When cutting surfaces with different bevels, multiple stop blocks with corresponding bevels need to be machined and replaced, making the operation cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems of existing sawing machines by proposing a sawing machine with an inclined saw blade.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A sawing machine for bevel cutting includes a bed and a sawing assembly mounted on the bed. A work platform is provided on the bed for mounting workpieces, and the sawing assembly is used to cut the workpieces on the work platform. The sawing assembly includes a saw frame, two saw wheels rotatably mounted on the saw frame, and a saw blade wound around the two saw wheels. The sawing assembly is horizontally slidably mounted on the bed, and a drive mechanism is also provided on the bed to drive the sawing assembly to move and feed for sawing. The two saw wheels are spaced vertically, and the upper and lower saw wheels are offset along the sawing direction so that the saw blade is tilted relative to the work platform, with the upper saw wheel closer to the workpiece and the lower saw wheel further away from the workpiece.

[0007] In the aforementioned type of bevel sawing machine, the angle of inclination of the saw blade relative to the working platform is 78°.

[0008] In the aforementioned bevel sawing machine, the working platform is provided with a clamping assembly for clamping the workpiece. The clamping assembly includes a stop block and a clamping cylinder, and the clamping cylinder pushes the workpiece to press against the stop block.

[0009] In the aforementioned bevel sawing machine, the clamping assembly further includes a slide block, and a number of stops are provided on the working platform. The stops are arranged horizontally at intervals along the sawing direction, and the stops are slidably disposed on the slide block in a direction perpendicular to the saw blade, and are fixed on the slide block by fasteners.

[0010] In the aforementioned bevel sawing machine, the clamping assembly further includes a slide block two, and there are two clamping cylinders. Both clamping cylinders are slidably mounted on the slide block two and are respectively fixed on the slide block two by fasteners. The slide block two is provided with a sliding groove, and the two clamping cylinders move along the sliding groove, and the sliding groove is inclined relative to the saw blade.

[0011] In the aforementioned bevel sawing machine, the two ends of the working platform are the loading end and the unloading end of the workpiece, respectively, and the loading end and the unloading end are each equipped with two sets of rollers.

[0012] In the aforementioned type of bevel sawing machine, two sets of rollers are arranged horizontally at intervals along the sawing direction. One set of rollers is set on the work platform, and the other set of rollers is set on the machine body via a bracket.

[0013] In the aforementioned type of bevel sawing machine, the saw frame is slidably mounted on the machine body via a slide rail.

[0014] In the aforementioned bevel sawing machine, the driving mechanism includes a lead screw, a nut, and a drive motor. The lead screw passes through the sawing machine, the nut is fixed to the saw frame and sleeved on the lead screw, and the two ends of the lead screw are rotatably mounted on the machine bed via mounting seats. The drive motor drives the lead screw to rotate, thereby causing the saw frame to move back and forth.

[0015] In the above-mentioned bevel sawing machine, the machine body is a hollow frame structure, the saw frame is "[" shaped, and two saw wheels are respectively located at the upper and lower ends of the saw frame. The lower saw wheel is inserted into the machine body, and the upper saw wheel is located above the work platform. An avoidance groove is opened on the work platform, and the saw blade passes through the avoidance groove and is wound around the two saw wheels.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The sawing assembly is tilted relative to the bed, thereby changing the direction of the saw blade's cutting surface. In the past, the saw blade's cutting surface was perpendicular to the workpiece. In this invention, the saw blade is tilted 12° in the cutting direction, which maximizes the reproduction of the effect of manual cutting with a saw, thereby improving cutting efficiency and stability.

[0018] 2. Each stop can be adjusted individually. When all stops are set parallel to the saw blade, the cut surface after the saw blade cuts is flat. By changing the position of the stops, the inclination of the contact surface between the workpiece and the stops is changed, and the cut surface after the saw blade cuts is oblique. Adjust the position of the stops to adjust different inclinations accordingly.

[0019] 3. Adjust the position of the clamping cylinders for workpieces of different sizes. When the workpiece is long, adjust the two clamping cylinders outward to increase the distance. When the workpiece is short, adjust the two clamping cylinders inward to increase the distance. This makes it more adaptable. Attached Figure Description

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figure 1 As shown, the present invention provides a special saw for bevel cutting, which includes a bed 1 and a sawing assembly disposed on the bed 1. The bed 1 is provided with a work platform 2 for mounting workpieces, and the sawing assembly is used to cut the workpieces on the work platform 2. The sawing assembly includes a saw frame 3, two saw wheels 4 rotatably disposed on the saw frame 3, and a saw blade 5 closedly wound around the two saw wheels 4.

[0027] like Figure 2As shown, the sawing assembly is horizontally slidably mounted on the bed 1. The bed 1 also has a drive mechanism for moving the sawing assembly horizontally for feeding and sawing. Two saw wheels 4 are spaced vertically apart, and the upper and lower saw wheels 4 are offset along the sawing direction so that the saw blade 5 is tilted relative to the work platform 2. The upper saw wheel 4 is closer to the workpiece, and the lower saw wheel 4 is farther away from the workpiece. The tilt angle of the saw blade 5 relative to the work platform 2 is 78°.

[0028] like Figure 3 As shown, the working platform 2 is equipped with a clamping assembly for clamping workpieces. This clamping assembly includes a stop block 7 and a clamping cylinder 9. The clamping cylinder 9 pushes the workpiece to press against the stop block 7. The clamping assembly also includes a slide block 6. Several stops 7 are provided on the working platform 2, arranged horizontally at intervals along the sawing direction. The stops 7 are slidably mounted on the slide block 6 in a direction perpendicular to the saw blade 5 and are fixed to the slide block 6 by fasteners. The clamping assembly also includes a second slide block 8. There are two clamping cylinders 9, both slidably mounted on the second slide block 8 and fixed to it by fasteners. The second slide block 8 has a groove along which the two clamping cylinders 9 move horizontally, and the groove is inclined relative to the saw blade 5.

[0029] The two ends of the work platform 2 are the loading end and the unloading end of the workpiece, respectively, and each end is equipped with two sets of rollers 14. The two sets of rollers 14 are arranged horizontally at intervals along the sawing direction. One set of rollers 14 is set on the work platform 2, and the other set of rollers is set on the bed 1 through a bracket 15. By adding rollers 14 at the loading and unloading ends of the work platform 2, the workload of loading and unloading can be reduced.

[0030] like Figure 4 As shown, the saw frame 3 is slidably mounted on the bed 1 via a slide rail. The drive mechanism includes a lead screw 10, a nut 11, and a drive motor 12. The lead screw 10 passes through the saw, and the nut 11 is fixedly connected to the saw frame 3 and sleeved on the lead screw 10. The two ends of the lead screw 10 are rotatably mounted on the bed 1 via mounting seats 16. The drive motor 12 drives the lead screw 10 to rotate, thereby causing the saw frame 3 to move back and forth.

[0031] like Figure 4 As shown, the saw bed 1 is a hollow frame structure. The saw frame 3 is "[" shaped, with two saw wheels 4 positioned at the upper and lower ends of the saw frame 3. The lower saw wheel 4 is inserted into the saw bed 1, and the upper saw wheel 4 is located above the work platform 2. The work platform 2 has a clearance groove 13, through which the saw blade 5 passes and wraps around the two saw wheels 4. By inserting the saw frame 3 into the hollow saw bed 1 and ensuring sufficient space for the saw frame 3 to move, the entire sawing machine structure becomes more compact and rational.
