Abstract
Description
Technical Field
[0001] This utility model relates to the field of band saw technology, specifically a guiding device for a band saw. Background Technology
[0002] Band saws are machine tools used for sawing various metal materials. They are classified by structure as horizontal and vertical, and by function as semi-automatic, fully automatic, and CNC. Horizontal band saws can be further divided into double-column and scissor types. During use, a guiding device is required to ensure that the workpiece is perpendicular to the saw blade at a 90-degree angle.
[0003] For example, a band saw guide device with announcement number "CN221910065U" has a feeding guide function. This structure is simple and facilitates guiding materials of different sizes, improving its practicality. However, when clamping materials, the device uses the spring force to limit the material's movement. The force generated during cutting causes the material to vibrate, resulting in poor cutting performance. Furthermore, when feeding materials, the material easily slips, making cutting impossible and causing the device to malfunction. Utility Model Content
[0004] The purpose of this invention is to solve the problems of using the elastic force of a spring to limit the material, which causes the material to vibrate during cutting, resulting in poor cutting effect, and the material easily slipping when loading, making it impossible to cut and causing the device to malfunction. Therefore, a guiding device for a band saw is proposed.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] Design a guide device for a band saw, including a first horizontal plate and a second horizontal plate. The upper end of the first horizontal plate is slidably connected to the second horizontal plate. The upper end of the second horizontal plate is fixedly connected to a first housing. The first housing has a pressing structure inside. The upper end of the second horizontal plate is fixedly connected to a clamping block. The lower end of the first horizontal plate is fixedly connected to a second housing. The second housing has a pushing structure inside. The first horizontal plate is threadedly connected to multiple bolts.
[0007] Preferably, the clamping structure includes a hydraulic cylinder, the left end of which is fixedly connected to the first housing, and the output end of the hydraulic cylinder is fixedly connected to a bent plate. The bent plate is rotatably connected to both ends of a circular roller via bearings. The outer wall of the circular roller abuts against a clamping plate. Both ends of the clamping plate are fixedly connected to circular rods, and a torsion spring is sleeved on the outer wall of the circular rods.
[0008] Preferably, the round rod is rotatably connected to the first housing via a bearing, and the two ends of the torsion spring are fixedly connected to the clamping plate and the first housing, respectively.
[0009] Preferably, the pushing structure includes a motor, the output end of which is fixedly connected to a first straight rod, the end of which is fixedly connected to a cylinder, the outer wall of which is slidably connected to a second straight rod, one end of which is movably connected to a second housing via a pin, and the other end of which is movably connected to a first slider via a pin, and the first slider and the second slider are slidably connected.
[0010] Preferably, the motor is fixedly connected to the rear end of the second housing, and the output shaft of the motor is rotatably connected to the second housing via a bearing.
[0011] Preferably, the outer wall of the second slider is slidably connected to the first horizontal plate, and the upper end of the second slider is fixedly connected to the second horizontal plate.
[0012] The guiding device for a band saw proposed in this utility model has the following advantages:
[0013] By cooperating with the clamping structure and the clamping block, the hydraulic cylinder is activated. The output end of the hydraulic cylinder extends, causing the bending plate to move. The movement of the bending plate causes the circular roller to move, and the movement of the circular roller causes the clamping plate to rotate around the circular rod, so that the end of the clamping plate is pressed against the object to be cut, thus fixing it and preventing the object from shifting during cutting, thereby improving the cutting quality.
[0014] Through the cooperation of the pushing structure and the clamping structure, the motor drives the first straight rod to rotate. The rotation of the first straight rod causes the cylinder to slide inside the second straight rod, which in turn causes the second straight rod to swing around the lower end pin. The swinging of the second straight rod causes the first slider to slide on the second slider, which in turn causes the second slider to move. The movement of the second slider causes the second horizontal plate to move. The movement of the second horizontal plate causes the clamping structure and clamping block to move. The movement of the clamping structure and clamping block causes the item to be cut to move, conveying the item to the band saw for cutting. This prevents the material from slipping during feeding, allowing for normal feeding and ensuring the normal operation of the device. Attached Figure Description

[0030] Working principle:
[0031] First, the device is fixed to the band saw with bolts 8. When cutting, the item to be cut is placed above the clamping blocks 5 to prepare for the cutting work.
[0032] Fixed job:
[0033] Start the hydraulic cylinder 401. The output end of the hydraulic cylinder 401 extends and drives the bending plate 402 to move. The movement of the bending plate 402 drives the circular roller 403 to move. The movement of the circular roller 403 drives the clamping plate 404 to rotate around the circular rod 405, so that the end of the clamping plate 404 is pressed against the item to be cut, thus completing the fixation of the item.
[0034] Cutting work;
[0035] When the external power supply of motor 701 is connected, motor 701 is started, which drives the first straight rod 702 to rotate. The rotation of the first straight rod 702 drives the cylinder 703 to slide inside the second straight rod 704, which in turn drives the second straight rod 704 to swing around the lower end pin. The swing of the second straight rod 704 drives the first slider 705 to slide in the second slider 706, which in turn drives the second slider 706 to move. The movement of the second slider 706 drives the second horizontal plate 2 to move. The movement of the second horizontal plate 2 drives the pressing structure 4 and the clamping block 5 to move. The movement of the pressing structure 4 and the clamping block 5 drives the object to be cut to move, and the object to be cut is transported to the band saw for cutting.
[0036] After cutting is completed, motor 701 continues to rotate, driving the second horizontal plate 2 back to the initial position. Then, motor 701 is turned off, and the output end of hydraulic cylinder 401 is shortened to release the fixation on the item, allowing the item to be removed.
[0037] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
