Description

Technical Field

[0001] This invention relates to the field of horizontal metal band saw technology, specifically a high-efficiency horizontal metal band saw. Background Technology

[0002] A horizontal band saw is a machine tool used for metal cutting. Its working principle is to cut metal materials by using the tension of the band saw blade and the centrifugal force generated by its high-speed rotation. During the cutting of metal plates, the horizontal band saw will generate a large amount of debris, which will remain on the processing table and need to be cleaned by a waste disposal mechanism.

[0003] Publication No. CN222627107U discloses a horizontal metal band saw with a cooling function. When cooling of the band saw body is required, the spray nozzle can be turned on to spray water onto the saw teeth and workpiece for cooling. Then, the forward and reverse rotation function of the motor is turned on, so that the moving block can drive the spray nozzle to move back and forth on both sides of the surface of the band saw body, thereby cooling the entire sawing area. This avoids the problem of existing spray nozzles being unable to effectively cool the entire sawing area. When water containing debris enters the filter box, it will pass through the first filter plate and the second filter plate to achieve layered filtration, increase the filtration effect of the filter box, and more effectively capture debris of different sizes. However, this patent still has the following problems in actual use:

[0004] Although this horizontal metal band saw with cooling function can cool the saw teeth and workpiece by spraying water, the continuous rotation of the saw teeth causes cooling water and cutting debris to splash everywhere, making it difficult to collect the cutting debris and resulting in a large amount of mud on the cutting table, which affects subsequent metal cutting. In addition, the amount of water sprayed cannot be controlled. When the amount of water sprayed is too small, it is not conducive to cooling the saw teeth. When the amount of water sprayed is too large, it will waste water resources. Furthermore, excessive water contact with the saw teeth will cause cooling water to splash.

[0005] Therefore, a high-efficiency horizontal metal band saw is proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a high-efficiency horizontal metal band saw to solve the problems mentioned in the background art, which are caused by the continuous rotation of the saw teeth, resulting in the splashing of cooling water and cutting debris everywhere. This makes it difficult to collect the cutting debris and causes a large amount of mud to accumulate on the cutting table, affecting subsequent metal cutting. In addition, the amount of water sprayed cannot be controlled. When the amount of water sprayed is too small, it is not conducive to cooling the saw teeth. When the amount of water sprayed is too large, it will cause water waste. At the same time, excessive water contact with the saw teeth will cause the cooling water to splash.

[0021] Compared with the prior art, the beneficial effects of this invention are as follows: This high-efficiency horizontal metal band saw can automatically adjust the water output of the quantitative water pipe according to the cutting depth of the workpiece. Simultaneously, utilizing the guide grooves on the surfaces of the vertical and inclined guides, the cooling water flows down along the guide grooves, cooling not only the top of the workpiece but also the band saw body. Under the action of the cooling water, dust generated during cutting can be reduced. The rotation of the clamping rotating rod causes the clamping sliding sleeve to slide relative to the outside of the clamping sliding rod, while simultaneously driving the inclined roller support to move relative to the outside. The second conveying roller clamps both sides of the workpiece, thereby improving the stable conveying of curved workpieces. The specific details are as follows:

[0022] 1. By setting up a cooling and cleaning mechanism, not only can the electric telescopic tube drive the quantitative water outlet pipe to move up and down, but when the bottom of the inclined guide contacts the top of the workpiece, the inclined guide drives the vertical guide and the sealing piston to move upward. When the sealing piston separates from the bottom of the quantitative water outlet pipe, the cooling water in the cooling water tank is pumped into the electric telescopic tube by the water pump and flows out through the quantitative water outlet pipe. The water output of the quantitative water outlet pipe can be automatically adjusted according to the cutting depth of the workpiece. At the same time, the guide grooves on the surface of the vertical guide and the inclined guide allow the cooling water to flow down with the guide grooves, which can not only cool the top of the workpiece, but also cool the band saw body. Under the action of the cooling water, the dust generated during cutting can be effectively cooled. Dust is treated to prevent dust from flying around. The first sprocket drive assembly and the cutting drive roller are rotated by the cutting motor. The rotation of the band saw body is achieved by the transmission connection between the cutting drive roller, the band saw body and the cutting driven roller, thereby cutting the workpiece. The band saw body can be corrected by the correction bracket and correction roller to keep the band saw body and the cutting part of the workpiece in a vertical direction, improving the stability of the workpiece cutting. At the same time, it can protect the band saw body and prevent it from breaking. The band saw bracket is raised and lowered by the electric telescopic rod to achieve the cutting of the workpiece. The collection box can collect the cutting debris and cooling water and discharge them through the drain valve.

[0023] 2. By setting up a conveyor protection mechanism, not only can the clamping motor drive the clamping bidirectional threaded rod to rotate, causing the two clamping threaded sleeves to move relative to the clamping connecting plate and the first clamping bracket, but the elastic force of the first clamping spring can also cause the clamping sliding sleeve to move the sliding protective cover up and down on the outside of the clamping sliding rod. Under the action of the rotating support and the rotating spring, the rotating clamping block can be pressed and fixed on the surface of the workpiece, improving the stability of the workpiece cutting. At the same time, the sliding protective cover and the fixed protective cover can shield the dust and cooling water mixture generated during cutting, preventing the mixture from flying around. The conveyor motor drives... The drive sprocket and drive chain rotate, and the chain limit bracket limits the movement of the drive chain to prevent slippage between the drive chain and drive sprocket, which would affect the conveying of the workpiece. The lifting cylinder drives the lifting plate to move up and down. When the second conveying roller at the bottom of the horizontal roller bracket contacts the top of the workpiece, the workpiece is clamped and conveyed. When the top of the workpiece is arc-shaped, the rotation of the clamping rotating rod causes the clamping sliding sleeve to slide relative to the outside of the clamping sliding rod, while driving the tilting roller bracket to move relative to the workpiece. The second conveying roller clamps both sides of the workpiece, thereby improving the stable conveying of arc-shaped workpieces. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-6This invention provides a technical solution: a high-efficiency horizontal metal band saw, including a cooling and cleaning mechanism 1 and a band saw body 122 installed inside the cooling and cleaning mechanism 1. A conveying and protective mechanism 2 is provided on one side of the cooling and cleaning mechanism 1, and a second clamping bracket 223 is provided on the top of the conveying and protective mechanism 2. The cooling and cleaning mechanism 1 includes a band saw support 101, with connecting hinges 102 symmetrically installed on the top of the band saw support 101. A band saw cover plate 103 is rotatably connected to the outer sides of the two connecting hinges 102. A cooling water tank 104 is fixedly installed on one side of the middle of the band saw cover plate 103. Cooling water... A water tank plug 105 is threaded onto one side of the top of the cooling water tank 104. A water pump 106 is fixedly installed at the bottom of the cooling water tank 104. An electric telescopic pipe 107 is fixedly installed at the bottom of the water pump 106. A support chassis 108 is fixedly installed at the bottom of the electric telescopic pipe 107. A first connecting spring 109 is fixedly installed at the top of the support chassis 108. A metering water outlet pipe 110 is fixedly installed at the bottom of the support chassis 108. A fixed bracket 111 is fixedly installed on the inner top of the metering water outlet pipe 110. A water outlet telescopic rod 112 is fixedly installed at the bottom of the fixed bracket 111. A water outlet spring 113 is slidably connected to the outer side of the water telescopic rod 112. A sealing piston 114 is fixedly installed at the bottom of the water outlet spring 113. A vertical guide 115 is installed at the center of the bottom of the sealing piston 114. An inclined guide 116 is fixedly installed at the bottom of the vertical guide 115. The metering water outlet pipe 110 is moved up and down by the electric telescopic tube 107. When the bottom of the inclined guide 116 contacts the top of the workpiece, the inclined guide 116 drives the vertical guide 115 and the sealing piston 114 to move upward. When the sealing piston 114 contacts the bottom of the metering water outlet pipe 110... During separation, the cooling water in the cooling water tank 104 is pumped into the electric telescopic pipe 107 by the water pump 106, and flows out through the metering water outlet pipe 110. The water output of the metering water outlet pipe 110 can be automatically adjusted according to the cutting depth of the workpiece. At the same time, the cooling water flows down with the guide grooves on the surface of the vertical guide 115 and the inclined guide 116, which not only cools the top of the workpiece, but also cools the band saw body 122. Under the action of the cooling water, the dust generated during cutting can be reduced, avoiding the phenomenon of dust flying around.

[0038] Please see Figures 5-7A band saw cover plate 103 is symmetrically provided with fixing bolts 117 on the side away from the connecting hinge 102. The band saw cover plate 103 is fixedly connected to the band saw bracket 101 by the fixing bolts 117. A sprocket limit cover 118 is fixedly installed on one side of the top of the band saw bracket 101. A cutting motor 119 is fixedly installed on one side of the inside of the sprocket limit cover 118. The output end of the cutting motor 119 is fixedly connected to a first sprocket drive assembly 120. A cutting drive roller 121 is symmetrically installed on one side of the first sprocket drive assembly 120. The band saw body 122 is drivenly connected to the cutting drive roller 121. A cutting driven roller 123 is symmetrically drivenly connected to the side of the band saw body 122 away from the cutting drive roller 121. Correction fixing blocks 124 are symmetrically installed on the inner bottom of the band saw bracket 101. Correction brackets 125 are symmetrically installed on one side of the top of the correction fixing blocks 124. Rotating brackets 126 are symmetrically installed on one side of each of the two correction brackets 125. A correction roller 127 is rotatably connected between the two rotating brackets 126. The correction roller 127 rotates with the band saw body 122. The band saw body 122 is symmetrically equipped with electric telescopic rods 128 at its bottom. A collection box 129 is fixedly installed at the bottom of the electric telescopic rods 128, and a drain valve 130 is fixedly installed on one side of the bottom of the collection box 129. The cutting motor 119 drives the first sprocket transmission assembly 120 and the cutting drive roller 121 to rotate. Utilizing the transmission connection between the cutting drive roller 121, the band saw body 122, and the cutting driven roller 123, the band saw body 122 can rotate, thereby achieving workpiece cutting. (The last sentence appears to be incomplete and possibly refers to a different topic.) The bracket 125 and the correction roller 127 can correct the band saw body 122, so that the band saw body 122 and the part of the workpiece being cut are always kept vertical, improving the stability of the workpiece cutting. At the same time, they can protect the band saw body 122 and prevent it from breaking. The band saw bracket 101 is moved up and down by the electric telescopic rod 128, thereby realizing the cutting of the workpiece. The collection box 129 can collect the cutting debris and cooling water, and discharge them through the drain valve 130.

[0039] Please see Figure 1 , Figures 8-10The conveying protection mechanism 2 includes a conveying bracket 201, which is fixedly installed on the top of the collection box 129. A controller 202 is fixedly installed on the front of the conveying bracket 201. A clamping bracket 203 is fixedly installed at one end of the conveying bracket 201. A clamping motor 204 is fixedly installed on the outside of the clamping bracket 203. A clamping bidirectional threaded rod 205 is fixedly connected to the output end of the clamping motor 204.

A first clamping bracket 208 is fixedly installed at the end of the clamping connecting plate 207. A clamping sliding rod 209 is fixedly installed inside the first clamping bracket 208. A clamping sliding sleeve 210 is slidably connected to the outside of the clamping sliding rod 209. A first clamping spring 211 is fixedly installed on the top of the clamping sliding sleeve 210. A sliding protective cover 212 is fixedly installed on one side of the clamping sliding sleeve 210. Rotating supports 213 are symmetrically installed on the inner side of the sliding protective cover 212. A rotating spring 214 is rotatably connected to the outer side of the rotating support 213. A rotating clamping block 215 is fixedly installed at the end of the rotating spring 214. A fixed protective cover 216 is symmetrically installed on the side of the conveying bracket 201 near the sliding protective cover 212. The clamping motor 204 drives the clamping bidirectional threaded rod 205 to rotate, so that the two clamping threaded sleeves 206 drive the clamping connecting plate 207 and the first clamping bracket 208 to move relative to each other. The elastic force of the first clamping spring 211 causes the clamping sliding sleeve 210 to drive the sliding protective cover 212 to slide up and down on the outside of the clamping sliding rod 209. Under the action of the rotating support 213 and the rotating spring 214, the rotating clamping block 215 can press and fix the surface of the workpiece, improving the stability of the workpiece cutting. At the same time, the sliding protective cover 212 and the fixed protective cover 216 are used to shield the dust and cooling water mixture generated during cutting, avoiding the phenomenon of the cooling water and dust mixture flying around.

[0040] Please see Figure 1 , Figure 2 , Figures 8-11The conveying bracket 201 has a through slot 217 near the top of the collection box 129. Chain limiting brackets 218 are symmetrically installed on both sides of the inside of the conveying bracket 201. A transmission chain 219 is slidably connected inside the chain limiting bracket 218. Several transmission sprockets 220 are meshed inside the transmission chain 219. A first conveying roller 221 is fixedly installed between two transmission sprockets 220. A conveying motor 222 is fixedly installed on one side of the conveying bracket 201. The output end of the conveying motor 222 is fixedly connected to the transmission sprocket 220. A second pressing bracket 223 is fixedly installed on the top of the conveying bracket 201. A lifting cylinder 224 is fixedly installed on the inner top of the support 223. A lifting plate 225 is fixedly installed on the bottom of the lifting cylinder 224. A lifting sliding sleeve 226 is fixedly installed around the lifting plate 225. A lifting sliding rod 227 is slidably connected inside the lifting sliding sleeve 226. The lifting sliding rod 227 is fixedly installed on the top of the conveying support 201. A clamping rotating rod 228 is rotatably connected around the bottom of the lifting plate 225. A clamping sliding sleeve 229 is rotatably connected to the bottom of the clamping rotating rod 228. A clamping sliding rod 230 is slidably connected inside the clamping sliding sleeve 229. A clamping device is fixedly installed on the outer side of the clamping sliding rod 230. The sliding frame 231 has a clamping spring 232 fixedly installed on one side of the clamping sliding sleeve 229. Several second compression springs 233 are fixedly installed at the bottom center of the clamping sliding frame 231. A horizontal roller bracket 234 is fixedly installed at the bottom of the second compression springs 233. Inclined roller brackets 235 are fixedly installed at the bottom of the clamping sliding sleeves 229 on both sides. Several second conveying rollers 236 are rotatably connected inside both the horizontal roller bracket 234 and the inclined roller bracket 235. The conveying motor 222 drives the transmission sprocket 220 and the transmission chain 219 to rotate. The chain limiting bracket 218 prevents the transmission chain from... Slippage occurs between 219 and the transmission sprocket 220, affecting the conveying of the workpiece. The lifting cylinder 224 drives the lifting plate 225 to move up and down. When the second conveying roller 236 at the bottom of the horizontal roller bracket 234 contacts the top of the workpiece, the workpiece can be clamped and conveyed. When the top of the workpiece is arc-shaped, the rotation of the clamping rotating rod 228 causes the clamping sliding sleeve 229 to slide relative to the outside of the clamping sliding rod 230, while driving the tilting roller bracket 235 to move relative to the outside. The second conveying roller 236 clamps the two sides of the workpiece, thereby improving the stable conveying of the arc-shaped workpiece.

[0041] Working principle: Before using this high-efficiency horizontal metal band saw, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 11As shown, firstly, the electric telescopic tube 107 drives the quantitative water outlet tube 110 to move up and down. When the bottom of the inclined guide tube 116 contacts the top of the workpiece, the inclined guide tube 116 drives the vertical guide tube 115 and the sealing piston 114 to move upward. When the sealing piston 114 separates from the bottom of the quantitative water outlet tube 110, the cooling water in the cooling water tank 104 is pumped into the electric telescopic tube 107 by the water pump 106 and flows out through the quantitative water outlet tube 110. The water output of the quantitative water outlet tube 110 can be automatically adjusted according to the cutting depth of the workpiece. At the same time, the guide grooves on the surface of the vertical guide tube 115 and the inclined guide tube 116 allow the cooling water to flow down with the guide grooves. This not only cools the top of the workpiece but also cools the band saw body 122. Under the action of the cooling water, the dust generated during cutting can be reduced, preventing dust from flying around.

[0042] Secondly, the first sprocket transmission assembly 120 and the cutting drive roller 121 are driven to rotate by the cutting motor 119. Utilizing the transmission connection between the cutting drive roller 121, the band saw body 122, and the cutting driven roller 123, the band saw body 122 can be rotated, thereby achieving workpiece cutting. The correction bracket 125 and correction roller 127 can correct the band saw body 122, ensuring that the band saw body 122 and the workpiece cutting area remain vertical, improving the stability of workpiece cutting. At the same time, the band saw body 122 can be protected to prevent breakage. The band saw bracket 101 is moved up and down by the electric telescopic rod 128, thereby achieving workpiece cutting. The collection box 129 can collect the cutting debris and cooling water, which are then discharged through the drain valve 130.

[0043] Finally, the clamping motor 204 drives the clamping bidirectional threaded rod 205 to rotate, causing the two clamping threaded sleeves 206 to move relative to the clamping connecting plate 207 and the first clamping bracket 208. The elastic force of the first clamping spring 211 causes the clamping sliding sleeve 210 to move the sliding protective cover 212 up and down on the outside of the clamping sliding rod 209. Under the action of the rotating support 213 and the rotating spring 214, the rotating clamping block 215 can press and fix the surface of the workpiece, improving the stability of the workpiece cutting. Simultaneously, the sliding protective cover 212 and the fixed protective cover 216 shield the dust and cooling water mixture generated during cutting, preventing the mixture from flying around. The transmission sprocket is driven by the conveying motor 222. The transmission chain 219 rotates, and the chain limiting bracket 218 limits the transmission chain 219 and the transmission sprocket 220 to prevent slippage and thus affect the conveying of the workpiece. The lifting cylinder 224 drives the lifting plate 225 to move up and down. When the second conveying roller 236 at the bottom of the horizontal roller bracket 234 contacts the top of the workpiece, the workpiece can be clamped and conveyed. When the top of the workpiece is arc-shaped, the rotation of the clamping rotating rod 228 causes the clamping sliding sleeve 229 to slide relative to the outside of the clamping sliding rod 230, while driving the tilting roller bracket 235 to move relative to the workpiece. The second conveying roller 236 clamps the two sides of the workpiece, thereby improving the stable conveying of the arc-shaped workpiece.
