Abstract
Description
Technical Field
[0001] This utility model relates to the field of horizontal band sawing technology, and in particular to a horizontal metal band saw. Background Technology
[0002] A CNC horizontal metal band saw is a mechanical device used for cutting metal workpieces. It uses a saw blade as the cutting tool, and the cutting operation is achieved through horizontal movement. The application of CNC technology enables this type of metal band saw to achieve an automated and precise cutting process. A CNC horizontal metal band saw mainly consists of a machine body, a CNC system, a transmission system, and a cooling system, typically powered by a motor and transmission device. CNC horizontal metal band saws are widely used in the metal processing industry, and are particularly suitable for cutting large metal workpieces of various shapes and sizes.
[0003] By comparing a CNC horizontal metal band saw with patent publication number CN221269873U, this solution effectively reduces the direct transmission of vibrations generated during equipment operation to the ground through a bottom bearing component, a first damping component, a second damping component, a first limit tube, a second limit tube, a rubber connector, and a buffer spring. This prevents noise generation and avoids damage to the ground, ensuring a safe sound environment around the equipment. However, after the band saw has been cutting a workpiece for a long time, some debris may remain on the surface of the band saw. If this debris is not cleaned in time, the band saw may scratch the surface of the band saw during long-term movement due to friction with the device or workpiece. In severe cases, it may cause the band saw to break, resulting in unnecessary safety accidents. Utility Model Content

A rotating wheel 210 is rotatably mounted on the front end of the sliding seat 209. A rotary motor 211 is mounted on the rotating end of the rotating wheel 210. The output end of the rotary motor 211 is fixed to the rotating end of the rotating wheel 210 via a coupling. A metal saw blade 213 is mounted between the two rotating wheels 210. A protective cover 212 is provided at the front end of the rotating wheel 210. Multiple rollers 219 are rotatably mounted on the surface of the base frame 100. A fixing structure for clamping and fixing the metal saw blade 213 is provided at the metal saw blade 213. A cleaning structure for cleaning the surface of the metal saw blade 213 is provided on the front side of the protective cover 212.
[0032] The cleaning structure includes a water spray cylinder 221 located on the front side of the protective cover 212. The water spray cylinder 221 has a water storage chamber inside, which is a cone shape with the smaller end facing downwards. An adjusting column 228 is slidably installed inside the water spray cylinder 221. The adjusting column 228 is also a cone shape with the smaller end facing downwards, and there is an angle between the side wall of the adjusting column 228 and the interior of the water storage chamber. A water pump 224 is located below the water spray cylinder 221, and a water tank 226 is located on the lower side of the base frame 100. A filter screen 227 is installed at the top. A water pipe is provided between the water spray cylinder 221 and the water pump 224. A water pump 225 is provided between the water pump 224 and the water tank 226. A water spray pipe 223 is provided on the side of the water spray cylinder 221 near the metal saw blade 213. Two guide plates 229 are provided at the top of the base frame 100 near the water tank 226, which are symmetrically arranged in the front and back directions. A control structure for controlling the amount of water sprayed inside the water spray cylinder 221 is provided above the water spray cylinder 221.
[0033] The control structure includes a fixed plate 220 set above the water spray cylinder 221, the fixed plate 220 being fixedly connected to the vertical slide rail 202, the fixed plate 220 being rotatably connected to the one-way lead screw 203, and a connecting rod 222 being fixed between the fixed plate 220 and the adjusting column 228, the connecting rod 222 being slidably connected to the water spray cylinder 221.
[0034] The fixed structure includes a sliding frame 214 set above the transverse slide rail 206. Two sliding plates 215 symmetrically arranged in the front-back direction are slidably installed inside the sliding frame 214. Two clamping wheels 216 distributed in the front and back are installed at the bottom of the sliding plates 215. The metal saw blade 213 is located between the two clamping wheels 216. The sliding plates 215 and the sliding frame 214 are connected by bolts.
[0035] The clamping structure includes two clamping blocks 218 symmetrically arranged in the front-to-back direction below the gantry frame 201. The clamping blocks 218 are slidably connected to the base frame 100. A clamping hydraulic cylinder 217 is installed between the clamping blocks 218 and the base frame 100. The clamping blocks 218 are made of rubber. The cleaning structure sprays cutting fluid onto the surface of the metal saw blade 213 during cutting. At the same time, the deeper the metal saw blade 213 cuts the workpiece, the greater the amount of waste chips generated. Consequently, the amount of water sprayed by the cleaning structure increases, and the water pressure also increases. This further washes away the waste chips on the surface of the metal saw blade 213, reducing the adhesion of waste chips to the surface of the metal saw blade 213, reducing wear on the metal saw blade 213, and reducing the occurrence of breakage of the metal saw blade 213.
[0036] Working principle: First, the workpiece is transported between two clamping blocks 218. The two clamping hydraulic cylinders 217 are driven to move the two clamping blocks 218 towards each other to clamp and fix the workpiece in the middle. Then, the lifting motor 204 is driven to rotate the one-way screw 203, which moves the lifting plate 205 down and moves the metal saw blade 213 directly above the workpiece. Then, the rotary motor 211 is driven to rotate the rotating wheel 210, which makes the metal saw blade 213 rotate at high speed to cut the workpiece. The adjusting motor 208 is started to rotate the two-way screw 207, which moves the two sliding seats 209 away from each other and the two rotating wheels 210 away from each other, thereby adjusting the tension of the metal saw blade 213.
[0037] Then, when cutting the workpiece, the water pump 224 draws the cutting fluid from the water tank 226 into the water spray cylinder 221, and then sprays it outward through the water spray pipe 223, spraying it onto the surface of the metal saw blade 213. On the one hand, it cools and lubricates the metal saw blade 213, and on the other hand, it washes away the residual waste on the surface of the metal saw blade 213. The waste is carried by the cutting fluid into the water tank 226 below, and the cutting fluid is filtered by the filter screen 227 at the upper end of the water tank 226. The waste is filtered onto the filter screen 227, and then the water pump 224 circulates the filtered cutting fluid and sprays it out through the water spray pipe 223, so as to achieve the effect of recycling the cutting fluid.
[0038] When the metal saw blade 213 moves downward, it also drives the water spray pipe 221 downward. As a result, there will be a certain gap between the inner wall of the water storage chamber inside the water spray pipe 221 and the side wall of the adjusting column 228. The greater the downward movement of the water storage chamber, the larger the gap between the two, and the greater the amount of water sprayed through the water spray pipe 223. Therefore, when the metal saw blade 213 cuts the workpiece deeper, the amount of water sprayed by the water spray pipe 223 is greater and the spray pressure is also increased. This can better wash off the waste chips on the surface of the metal saw blade 213, reduce the waste chips adhering to the surface of the metal saw blade 213, reduce the wear of the metal saw blade 213, and reduce the occurrence of breakage of the metal saw blade 213.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
