Description

Technical Field

[0001] This utility model relates to the field of band sawing technology, and in particular to a vertical rotary band saw. Background Technology

[0002] A sawing machine is a machining tool used to cut workpieces to the required length or shape. It consists of a set of electric saw blades that move up and down to achieve the cutting, greatly improving processing efficiency and accuracy. There are many types of sawing machines, including manual sawing machines, horizontal sawing machines, vertical sawing machines, and bevel sawing machines. The appropriate type of sawing machine is selected based on the processing requirements.

[0003] Larger materials are typically cut using a vertical band saw. Chinese Patent No. CN220278451U discloses a vertical band saw. It uses a rotating motor within a cleaning frame to rotate a transmission gear on one side, with the two transmission gears meshing together. This allows the band saw passing through the cleaning frame to be cleaned. An air pump draws in air from the inlet pipe and discharges it through the exhaust nozzle to perform air cleaning of the band saw. It also blows out debris from the guide hopper through the slag discharge pipe.

[0004] The spindle is the drive unit for the band saw blade, which cuts the workpiece by rotating the spindle. It can cut wherever the saw blade reaches, making it more flexible than a traditional table saw. When cutting, the workpiece is usually placed on the table and then pushed to contact the band saw blade to complete the cutting. However, during the manual pushing of the workpiece, it is easy for the workpiece to shift, resulting in a rough cut surface and affecting the processing accuracy. Utility Model Content

[0005] In view of the problem that the object is prone to displacement during the existing manual pushing process, resulting in a rough cutting surface and affecting the processing accuracy, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a vertical rotary band saw, which aims to: position the band saw blade by pushing the object fixed by the clamping arm and positioning the position slider under the restriction of the guide rail, thereby ensuring the accuracy of the cutting position.

[0007] To solve the above technical problems, this utility model provides the following technical solution: a vertical rotary band saw, which includes a base and a band saw blade, the band saw blade being movably connected to the inner side of the base, and a processing component and an adjusting component being provided on the inner side of the base, the adjusting component being located at the top of the processing component;

[0008] The processing component includes a positioning element, which includes a guide rail. The guide rail is fixedly installed on the inner side of the machine base, and positioning sliders are arranged on the top of the guide rail. The positioning sliders are movably connected to both sides of the guide rail.

[0009] The positioning sliders are connected by a synchronous shaft, with each end of the synchronous shaft passing through a positioning slider. A central rod is fixedly installed at each end of the positioning slider, and the central rods are distributed on both sides of the guide rail via the synchronous shaft.

[0010] Both ends of the central rod are hinged with clamping arms, which are arranged parallel to each other, and the central rod is located at the connection between the clamping arms.

[0011] In a preferred embodiment of the vertical rotary band saw of this utility model, the clamping arms are connected by connecting rods, and the connecting rods are arranged parallel to each other. The connecting rods are connected by a double-ended screw, and the connecting rods are threaded to both ends of the double-ended screw. A hand lever is fixedly installed at one end of the double-ended screw that protrudes from the machine base.

[0012] In a preferred embodiment of the vertical rotary band saw of this utility model, a rubber sleeve is installed at the end of each clamping arm away from the central rod, and the rubber sleeve is distributed parallel to the connecting rod.

[0013] In a preferred embodiment of the vertical rotary band saw of this utility model, the processing assembly further includes a grinding component, which includes a base plate. The base plate is fixedly installed on the inner side of the machine base. A pressure plate is movably connected to the side of the band saw blade away from the base plate. Grinding wheels are arranged on the side of the pressure plate close to the base plate. The band saw blade is located between the base plate and the grinding wheels.

[0014] In a preferred embodiment of the vertical rotary band saw of this utility model, a top rod is connected to the side of the pressure plate away from the base plate, the top rod is movably connected to the inner side of the machine base by a spring, and a damping shaft is connected to the end of the top rod away from the pressure plate.

[0015] In a preferred embodiment of the vertical rotary band saw of this utility model, the grinding component further includes an air pump, which is fixedly installed on the surface of the machine base.

This ensures that the workpiece fixed by the clamping arm and the cutting line of the band saw blade are also on the same straight line as the center line of the guide rail, thus ensuring that the workpiece is not prone to deviation during movement and ensuring the accuracy of the cutting position.

[0019] 2. By contacting the side of the band saw blade without the saw blade with the base plate, and the side with the saw blade with the rotatable grinding wheel on the pressure plate connected to the top rod by the extended spring, the band saw blade is ground by the grinding wheel during the contact process, ensuring the sharpness of the band saw blade.

[0020] 3. The band saw blade is driven by an electrically driven drive wheel, which is constrained by the drive wheel and the receiving wheel. The T-shaped frame is raised and lowered in the machine base by rotating the threaded shaft, thereby adjusting the tension of the band saw blade and making the band saw blade cut the workpiece more smoothly and stably.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] Reference Figure 1-5 This is the first embodiment of the present invention, providing a vertical rotary band saw. The vertical rotary band saw includes a base 1 and a band saw blade 2. The band saw blade 2 is movably connected to the inner side of the base 1. A processing assembly 3 and an adjusting component 4 are arranged on the inner side of the base 1. The adjusting component 4 is located at the top of the processing assembly 3. The processing assembly 3 includes a positioning component 31, which includes a guide rail 311. The guide rail 311 is fixedly installed on the inner side of the base 1. Positioning sliders 312 are arranged on the top of the guide rail 311, and the positioning sliders 312 are movably connected to both sides of the guide rail 311. The positioning sliders 312 are connected by a synchronous shaft 313, with both ends of the synchronous shaft 313 passing through the positioning sliders 312. Both ends of the device 2 are fixedly mounted with a central rod 314. The central rod 314 is distributed on both sides of the guide rail 311 via a synchronous shaft 313. Both ends of the central rod 314 are hinged with clamping arms 315. The clamping arms 315 are arranged parallel to each other, and the central rod 314 is located at the connection between the clamping arms 315. The base 1 can ensure that the device remains horizontal when cutting. The band saw blade 2 can cut the object by contacting it. The center line of the guide rail 311 and the band saw blade 2 are on the same straight line. The positioning slider 312 moves synchronously via the synchronous shaft 313. The central rod 314 can act as the center of the deflection of the clamping arms 315 when they deflect, thereby fixing both ends of the object.

[0032] The clamping arms 315 are connected by connecting rods 316, which are arranged parallel to each other. The connecting rods 316 are connected by bidirectional screws 317, and the connecting rods 316 are threaded to both ends of the bidirectional screws 317. A hand lever 318 is fixedly installed on one end of the bidirectional screws 317 that protrudes from the machine base 1. The inner side of the connecting rods 316 is provided with threads that are compatible with the bidirectional screws 317. The threads in the connecting rods 316 are opposite in direction, which makes the clamping arms 315 parallel to each other. The bidirectional screws 317 pass through the entire connecting rods 316. The hand lever 318 is convenient for the palm to grip and rotate.

[0033] Rubber sleeves 319 are installed at the ends of the clamping arms 315 away from the center rod 314. The rubber sleeves 319 are distributed parallel to the connecting rod 316. The rubber sleeves 319 are made of silicone rubber. When the clamping arms 315 deflect and approach each other, they can cooperate with the deflection between the clamping arms 315 to increase the friction with the object, making the object less likely to fall off during processing.

[0034] The processing component 3 also includes a grinding component 32, which includes a base plate 321. The base plate 321 is fixedly installed on the inner side of the machine base 1. A pressure plate 322 is movably connected to the side of the band saw blade 2 away from the base plate 321. Grinding wheels 323 are arranged on the side of the pressure plate 322 close to the base plate 321. The band saw blade 2 is located between the base plate 321 and the grinding wheels 323. The side of the band saw blade 2 without the saw blade edge is in contact with the base plate 321. The grinding wheels 323 can rotate on the pressure plate 322. The pressure plate 322 grinds the band saw blade 2 by contacting the side of the band saw blade 2 with the saw blade edge, so that the band saw blade 2 maintains sufficient sharpness.

[0035] A top rod 324 is connected to the side of the pressure plate 322 away from the base plate 321. The top rod 324 is movably connected to the inside of the machine base 1 via a spring 325. A damping shaft 326 is connected to the end of the top rod 324 away from the pressure plate 322. The pressure plate 322 can move in a direction parallel to the base plate 321 in the groove in the machine base 1. When the spring 325 extends, it pushes the pressure plate 322 connected to the top rod 324 to move closer to the base plate 321, so that the grinding wheel 323 can make full contact with the band saw blade 2. The damping shaft 326 can reduce the influence of the deformation of the spring 325 on the band saw blade 2 and ensure the stability of the band saw blade 2 during operation.

[0036] The grinding component 32 also includes an air pump 327, which is fixedly installed on the surface of the base 1. The air pump 327 is provided with an air supply pipe 328, and the other end of the air supply pipe 328 is located on the top of the pressure plate 322. The air pump 327 supplies air to the groove of the pressure plate 322 through the air supply pipe 328 and removes the waste from the grinding wheel 323.

[0037] The adjusting component 4 includes a drive wheel 41 and a receiving wheel 42. The band saw blade 2 is connected to the drive wheel 41 and the outer side of the band saw blade 2 respectively. The receiving wheel 42 is movably connected to the top of the machine base 1 through a T-shaped frame 43. The T-shaped frame 43 is threadedly connected to the machine base 1 through a threaded shaft 44. The drive wheel 41 is electrically driven to enable the band saw blade 2 to achieve transmission under the restriction of the drive wheel 41 and the receiving wheel 42. The T-shaped frame 43 can be raised and lowered in the machine base 1 through the threaded shaft 44, thereby adjusting the tension of the band saw blade 2, making the band saw blade 2 smoother and more stable when cutting the workpiece.

[0038] In use, by rotating the corresponding levers 318, the connecting rods 316, under the influence of the opposite threads at both ends of the bidirectional screw 317, move closer to each other, causing the connected clamping arms 315 to deflect around the center rod 314, thus fixing both ends of the workpiece and pushing the workpiece closer to the band saw blade 2. The synchronous shaft 313 connected to the center rod 314 keeps the positioning slider 312 moving synchronously in the guide rail 311. The direction of movement remains parallel, and the center line of the guide rail 311 is on the same straight line as the band saw blade 2. This ensures that the workpiece fixed by the clamping arms 315 and the cutting line of the band saw blade 2 are also on the same straight line as the center line of the guide rail 311, thus ensuring that the workpiece is not prone to deviation during movement and ensuring the accuracy of the cutting position. When the band saw blade 2 is in motion, the side without the saw blade is... The band saw blade 2 contacts the base plate 321, and the side with the saw blade contacts the rotatable grinding wheel 323 on the pressure plate 322, which is connected to the push rod 324 via the extended spring 325. During the contact process, the grinding wheel 323 grinds the band saw blade 2 to ensure its sharpness. In this process, the damping shaft 326 reduces the influence of the spring 325 deformation on the band saw blade 2. At the same time, the air supply pipe 328 connected to the air pump 327 blows air into the groove outside the pressure plate 322 to clean the grinding wheel 323. The electrically driven drive wheel 41 enables the band saw blade 2 to be driven under the restriction of the drive wheel 41 and the receiving wheel 42. The T-shaped frame 43 is raised and lowered in the machine base 1 by rotating the threaded shaft 44, thereby adjusting the tension of the band saw blade 2 and making the band saw blade 2 smoother and more stable when cutting the workpiece.
