Description

Technical Field

[0001] This utility model relates to the field of metal tube processing technology, specifically to a batch cutting device for processing metal support tubes. Background Technology

[0002] In the industrial production field, metal support pipes are an important structural component and are widely used in many industries such as construction, machinery manufacturing, and rail transportation. During their processing, the cutting process is a key link to ensure the dimensional accuracy of the product and the quality of subsequent assembly.

[0003] The cutting and processing of metal support tubes mostly adopts the traditional manual operation mode. Workers manually move the metal tubes to the cutting station and fix them in place. They measure and mark the required cutting length using tools such as tape measures and calipers, and then operate the cutting saw to complete the cutting operation. This processing method mainly relies on manual operation experience. First, when manually fixing the metal tubes, uneven clamping force can easily cause the tubes to shake during the cutting process, affecting the cutting accuracy. Second, the manual measurement and marking method is easily affected by subjective factors such as the operator's skill level and fatigue, making it difficult to ensure the consistency of length of batch-cut parts. Third, the fixing, measurement and cutting process of a single tube needs to be completed step by step, which is cumbersome, labor-intensive and results in low production efficiency, which cannot meet the needs of modern industry for large-scale and high-efficiency production. Utility Model Content

[0004] The purpose of this invention is to provide a batch cutting device for processing metal support tubes, which has the advantages of continuous operation, uniform cutting length, and high production efficiency, and solves the problems of time-consuming and labor-intensive manual operation, poor consistency of batch products, and low production efficiency in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A batch cutting device for processing metal support tubes includes a bearing assembly. The bearing assembly comprises a base, a feeding assembly mounted on the upper end of the base, and a feeding box fixedly connected to the upper end of the base. Feeding rollers, distributed front and rear, are rotatably mounted on the inner walls of the upper and lower ends of the feeding box. The shafts of the feeding rollers pass through the upper inner wall of the feeding box and are fixedly connected to a worm gear. A worm is rotatably mounted on the upper end of the feeding box, meshing with the worm gear. A servo motor is also mounted on the upper end of the feeding box. The output end is connected to the worm gear shaft. The upper end of the base is also provided with a slide groove. A slider is slidably installed in the slide groove. A movable frame is fixed to the upper end of the slider. Several limit rollers with equal front and rear distances are rotatably installed on the inner walls of the upper and lower ends of the movable frame.

A cutting machine is fixed to the upper edge of the base. The conveyor seat corresponds to the inlet of the cutting machine. A fixing component is also installed on the upper end of the base.

[0006] Preferably, a belt conveyor is also installed at the front end of the base, and the upper end of the conveyor belt is flush with the upper end of the conveyor seat.

[0007] It is worth noting that the metal tube to be cut can be transported to the upper end of the conveyor seat by the belt conveyor, and then the feeding component will transport the metal tube at a fixed distance.

[0008] Preferably, a guide box is also fixedly connected to the upper end of the belt conveyor, and the lower opening of the guide box corresponds to the upper end of the conveyor belt of the belt conveyor.

[0009] It is worth noting that the guide box can guide the metal pipe to be cut to the upper end of the belt conveyor, allowing for continuous and uninterrupted conveying of the metal pipe.

[0010] Preferably, an electric cylinder is fixedly connected to the upper end of the base, and the output end of the electric cylinder is fixedly connected to the right end of the movable frame. The extension and retraction direction of the output end of the electric cylinder is the same as the extension direction of the slide groove.

[0011] It is worth noting that the output end of the electric cylinder can drive the movable frame to move left and right along the slide groove, thereby driving the limit roller to approach the conveyor seat, and cooperating with the feeding roller to clamp the metal tube to be cut, which facilitates the fixed-distance conveying of the metal tube.

[0012] Preferably, the upper end of the conveyor seat is provided with a groove, and several pulleys equidistant from front to back are rotatably installed in the groove. The outer walls of the feeding roller and the limiting roller are both fixed with soft pads. The upper end of the feeding box is fixed with a protective cover, and the servo motor, worm gear and worm wheel are all located inside the protective cover.

[0013] It is worth noting that: pulleys can improve the smoothness of metal tube movement and prevent jamming; soft pads can improve the clamping effect on metal tubes; and protective covers can protect the servo motor and worm gear structure, preventing dust and other impurities from affecting the operation of the worm gear.

[0014] Preferably, the fixing component includes a clamping seat fixed to the upper end of the base. The clamping seat is located between the conveyor seat and the cutting machine. The upper end of the clamping seat is flush with the upper end of the conveyor seat. Two electric cylinders, symmetrically arranged on the left and right, are fixed to the upper edge of the clamping seat. The output ends of the two electric cylinders are jointly fixed to a clamping box.

[0015] It is worth noting that the fixing component can fix the metal tube fed to the cutting machine, the clamping seat can support the metal tube, and the output end of the electric cylinder can drive the clamping box to move downward, which, together with the clamping seat, clamps and fixes the metal tube, improving the stability of the metal tube during cutting and ensuring the flatness of the cut.

The upper end of the tension spring is fixed to the upper edge of the sliding rod, and the lower end of the tension spring is fixed to the upper end of the clamping box.

[0017] It is worth noting that the tension spring can pull the slide rod downward along the sliding hole, thereby causing the clamping block to fit the outer surface of the metal tube, improving the clamping effect on the metal tube, and can be adapted to metal tubes of different outer diameters, thus increasing the clamping range.

[0018] Preferably, the left end of the clamping block is provided with a second sliding groove, the right end of the clamping block is fixedly connected with a second slider, the second slider is slidably installed in the second sliding groove of the adjacent clamping block, and the lower end of the clamping block and the upper end of the clamping seat are both fixedly connected with soft pads.

[0019] It is worth noting that by sliding the second slider in the groove of the adjacent clamping block, the clamping blocks can be effectively connected, which can further improve the stability of the clamping blocks moving up and down, thus better adapting to the outer wall of the metal tube. With the soft pad, the clamping and fixing effect on the metal tube can be improved, thereby ensuring that the cut of the metal tube is flat.

[0020] Preferably, a controller is fixedly connected to the right end of the base.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a conveyor seat to support a metal tube, pushing a movable frame to move left and right along a chute. This allows the limiting roller to fit against the outer wall of the metal tube, and it works in conjunction with the feeding roller to clamp and hold the outer wall of the metal tube. The output of the servo motor can drive the worm gear to rotate, thereby driving the worm wheel to rotate, allowing the front and rear feeding rollers to rotate synchronously. This drives the metal tube to move along the upper end of the conveyor seat into the fixing component. After the feeding component pushes the metal tube to a preset distance, the fixing component can fix the metal tube, and then the cutting machine can cut the metal tube to achieve batch cutting of metal tubes.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To address the problems of time-consuming and labor-intensive manual operations, poor batch product consistency, and low production efficiency in existing technologies, the following technical solution is proposed. Please refer to [link / reference]. Figures 1-5 ; A batch cutting device for processing metal support tubes includes a bearing assembly. The bearing assembly includes a base 101, with a feeding assembly mounted on the upper end of the base 101. The feeding assembly includes a feeding box 201 fixed to the upper end of the base 101. Feeding rollers 202, distributed front and rear, are rotatably mounted on the inner walls of the upper and lower ends of the feeding box 201. The shafts of the feeding rollers 202 pass through the upper inner wall of the feeding box 201 and are fixedly connected to a worm gear 203. A worm 204 is rotatably mounted on the upper end of the feeding box 201, meshing with the worm gear 203. A servo motor 205 is also mounted on the upper end of the feeding box 201, with the output end of the servo motor 205 connected to the worm gear 203. The base 101 is connected to the rotating shaft of 04. The upper end of the base 101 is also provided with a sliding groove 105. A slider 209 is slidably installed in the sliding groove 105. A movable frame 210 is fixedly connected to the upper end of the slider 209. Several limit rollers 212 with equal front and rear distances are rotatably installed on the inner walls of the upper and lower ends of the movable frame 210. The movable frame 210 corresponds to the feeding box 201. A conveyor seat 207 is also fixedly connected to the upper end of the base 101. The conveyor seat 207 is located between the movable frame 210 and the feeding box 201. A cutting machine 102 is fixedly connected to the upper edge of the base 101. The conveyor seat 207 corresponds to the inlet of the cutting machine 102. A fixing component is also installed on the upper end of the base 101.

[0027] The metal tube can be supported by the conveyor seat 207, which pushes the movable frame 210 to move left and right along the slide groove 105. This allows the limiting roller 212 to fit against the outer wall of the metal tube. It can work with the feeding roller 202 to clamp the outer wall of the metal tube. The output end of the servo motor 205 can drive the worm gear 204 to rotate, thereby driving the worm wheel 203 to rotate. This allows the two feeding rollers 202 to rotate synchronously, which can drive the metal tube to move along the upper end of the conveyor seat 207 into the fixed component. After the feeding component pushes the metal tube to a preset distance, the fixed component can fix the metal tube. Then, the cutting machine 102 cuts the metal tube to achieve batch cutting of metal tubes.

[0028] Please see Figure 3 A belt conveyor 103 is also installed at the front end of the base 101. The upper end of the conveyor belt of the belt conveyor 103 is flush with the upper end of the conveyor seat 207. The metal tube to be cut can be transported to the upper end of the conveyor seat 207 by the belt conveyor 103, and then the feeding component will transport the metal tube at a fixed distance. A guide box 104 is also fixed to the upper end of the belt conveyor 103. The lower opening of the guide box 104 corresponds to the upper end of the conveyor belt of the belt conveyor 103. The metal tube to be cut can be guided to the upper end of the belt conveyor 103 by the guide box 104, and the metal tube can be continuously and uninterruptedly transported.

[0029] Please see Figure 4An electric cylinder 211 is fixedly connected to the upper end of the base 101. The output end of the electric cylinder 211 is fixedly connected to the right end of the movable frame 210. The extension and retraction direction of the output end of the electric cylinder 211 is the same as the extension direction of the slide 105. The output end of the electric cylinder 211 can drive the movable frame 210 to move left and right along the slide 105, thereby driving the limiting roller 212 to approach the conveyor seat 207. In conjunction with the feeding roller 202, the metal tube to be cut is clamped, which facilitates the fixed-distance conveying of the metal tube. The upper end of the conveyor seat 207 is provided with a groove, and the rotation inside the groove... The feed box 201 is equipped with several pulleys 208 spaced equidistantly. The outer walls of the feed roller 202 and the limiting roller 212 are fixed with soft pads. The upper end of the feed box 201 is fixed with a protective cover 206. The servo motor 205, worm gear 204 and worm wheel 203 are all located inside the protective cover 206. The pulleys 208 can improve the smoothness of the metal tube movement and avoid jamming. The soft pads can improve the clamping effect on the metal tube. The protective cover 206 can protect the structure of the servo motor 205 and the worm gear 204 and worm wheel 203 and worm 204, and prevent dust and other impurities from affecting the operation of the worm wheel 203.

[0030] Please see Figure 5 The fixing component includes a clamping seat 301 fixed to the upper end of the base 101. The clamping seat 301 is located between the conveyor seat 207 and the cutting machine 102. The upper end of the clamping seat 301 is flush with the upper end of the conveyor seat 207. A pair of symmetrical electric cylinders 302 are fixed to the upper edge of the clamping seat 301. The output ends of the electric cylinders 302 are fixed to the clamping box 303. The fixing component can fix the metal tube conveyed to the cutting machine 102. The clamping seat 301 can support the metal tube. The output end of the electric cylinders 302 can drive the clamping box 303 to move downward, which works with the clamping seat 301 to clamp and fix the metal tube, improve the stability of the metal tube during cutting, and ensure the flatness of the cut.

[0031] The upper end of the clamping box 303 has several symmetrical sliding holes 304. Sliding rods 305 are slidably mounted on the inner walls of each sliding hole 304. Clamping blocks 307 are fixedly connected to the lower ends of each sliding rod 305. Tension springs 306 surround the outer walls of each sliding rod 305. The upper ends of the tension springs 306 are fixed to the upper edge of the sliding rods 305, and the lower ends are fixed to the upper end of the clamping box 303. The tension springs 306 can pull the sliding rods 305 downwards along the sliding holes 304, thereby causing the clamping blocks 307 to conform to the outer surface of the fitted metal tube, improving the clamping effect on the metal tube. This design allows for the adaptation to metal tubes of different outer diameters, enhancing the clamping performance. The clamping block 307 has a sliding groove 308 on its left end and a slider 309 fixedly connected to its right end. The slider 309 is slidably installed in the sliding groove 308 of the adjacent clamping block 307. Soft pads are fixedly connected to the lower end of the clamping block 307 and the upper end of the clamping seat 301. By sliding the slider 309 in the sliding groove 308 of the adjacent clamping block 307, each clamping block 307 can be effectively connected, which can further improve the stability of the clamping block 307's up and down movement, thereby better adapting to the outer wall of the metal tube. The soft pads can improve the clamping and fixing effect on the metal tube, thus ensuring that the cut of the metal tube is flat.

[0032] A controller is fixed to the right end of the base 101; the controller can synchronously control the servo motor 205, electric cylinder 211, electric cylinder 302, belt conveyor 103, etc., to ensure the distance of the conveyed metal tube, ensure equidistant conveying and cutting, and improve the uniformity of the length of the cut metal tube.

[0033] Working principle: This device synchronously coordinates feeding, conveying, positioning, fixing, and cutting through a controller to achieve automated batch cutting of metal tubes. The specific working steps and the functions and coordination of the parts are as follows: First, the metal tubes to be cut are guided neatly onto the conveyor belt of the belt conveyor 103 through the guide box 104 to prevent the metal tubes from deviating. After the belt conveyor 103 is started, its conveyor belt drives the metal tubes to move into the device. Since the upper end of the conveyor belt is flush with the upper end of the conveyor seat 207, the metal tubes can smoothly transition to the upper end of the conveyor seat 207. At this time, several pulleys 208 rotatably installed in the groove of the conveyor seat 207 play a role. When the metal tubes move, they drive the pulleys 208s to rotate, which greatly reduces the friction between the metal tubes and the conveyor seat 207.

[0034] The controller starts the electric cylinder 211, and its output end extends and retracts along the extension direction of the slide groove 105, driving the movable frame 210 fixed thereto to move. The lower end of the movable frame 210 slides stably along the slide groove 105 through the slider 209 to ensure that the movable frame 210 does not deviate when it moves. As the movable frame 210 approaches the metal tube on the conveyor seat 207, several limiting rollers 212 rotatably installed on the inner walls of the upper and lower ends of the movable frame 210 gradually fit against the outer wall of the metal tube, forming a clamping state with the front and rear feeding rollers 202 in the feeding box 201.

[0035] After clamping and positioning are completed, the controller starts the servo motor 205, and its output drives the worm gear 204 fixed to it to rotate. When the worm gear 204 rotates, it drives the worm wheel 203 to rotate synchronously, which in turn drives the two front and rear feeding rollers 202 to rotate synchronously in the same direction. The rotating feeding rollers 202 drive the clamped metal tube to move along the upper end of the conveyor seat 207 towards the fixed component through friction. The controller controls the number of rotations of the servo motor 205 to precisely control the conveying distance of the metal tube, ensuring that the length of each section of the metal tube to be cut is consistent.

[0036] When the metal tube is transported to the preset cutting position, the controller stops the servo motor 205, and the metal tube stops moving. At the same time, the controller starts the fixing component: first, the output end of the electric cylinder 302 extends and retracts downward, driving the clamping box 303, which is fixed to it, to move downward synchronously. During the downward movement of the clamping box 303, the slide rod 305, which is slidably installed in the sliding hole 304 through the upper end of the box, moves downward along the sliding hole 304 under the tension of the tension spring 306, thereby driving the clamping block 307 fixed to the lower end of the slide rod 305 to move closer to the outer wall of the metal tube. Since the slider 309 fixed to the right end of the clamping block 307 is slidably installed in the sliding groove 308 opened on the left end of the adjacent clamping block 307, multiple clamping blocks 307 can maintain synchronous and stable movement through the cooperation of the slider 309 and the sliding groove 308. Finally, all clamping blocks 307 are in contact with the outer wall of the metal tube, and together with the clamping seat 301, they form a firm clamp on the metal tube.

[0037] After the metal tube is fixed, the controller starts the cutting machine 102, which cuts the fixed metal tube. After a single cut, the controller stops the cutting machine 102 and simultaneously controls the output end of the electric cylinder 302 to extend and retract upward, causing the clamping box 303 to reset. The clamping block 307 moves upward under the action of the clamping box 303, releasing the metal tube. Then, the controller starts the servo motor 205 again, driving the next section of metal tube to continue to be transported to the preset position. At the same time, the belt conveyor 103 continuously transports the new metal tube to be cut to the conveyor seat 207. Throughout the process, the controller always synchronously coordinates the start and stop and the action rhythm of the servo motor 205, the electric cylinder 211, the electric cylinder 302, the belt conveyor 103, and the cutting machine 102 to ensure that the conveying distance of each section of metal tube is consistent and the cutting length is uniform, thus ensuring the quality and efficiency of batch cutting.

[0038] The metal tubes for batch cutting are arranged horizontally, meaning they are stacked sequentially in the guide box 104 along the conveying direction. Batch processing is achieved through continuous, uninterrupted conveying. This arrangement, combined with the device's multi-positioning structure, effectively avoids offset during conveying: First, the guide box 104 precisely guides the metal tubes to the belt conveyor 103 through a regular channel structure. The correspondence between its lower opening and the conveyor belt ensures the initial position of the metal tubes is centered, preventing offset during the loading stage. Second, the pulleys 208 on the conveyor seat 207 not only reduce frictional resistance, but their groove structure... The structure also forms a bottom limit for the metal tube. With the clamping design of the feeding roller 202 and the limiting roller 212, the electric cylinder 211 drives the movable frame 210 to move, so that the limiting roller 212 fits tightly against the outer wall of the metal tube and forms a ring-shaped clamp with the feeding roller 202. The soft pad increases the friction to prevent slippage and deviation. Finally, the clamping block 307 of the fixing component achieves synchronous fitting through the linkage structure of the slider 309 and the groove 308. With the elastic pressure of the tension spring 306, it can adapt to different tube diameters and form multi-point uniform clamping, further eliminating position deviations before cutting and ensuring the accuracy and stability of batch cutting.
