Description
Technical Field
[0001] This utility model relates to the technical field of sawing machine receiving table, specifically a multi-hole bending receiving table for a CNC sawing machine. Background Technology
[0002] A CNC band saw is a device for cutting steel pipes and plates. The machining accuracy of CNC band saws is generally not very high, and they are mostly used in material preparation workshops to cut various bars, pipes, and other profiles. The saw blade is driven by a drive wheel and a driven wheel. The cutting direction of the saw blade is controlled by a guide rail control frame. After adjusting the diameter of the band saw blade by adjusting the self-rotating bearing, the steel pipe is cut through the sweeper.
[0003] Patent document CN 206952625U discloses a multi-hole bending receiving table for a CNC saw. Its structure is simple and rationally designed. The receiving plate is made of bent iron plate with several long holes laser-cut, making it simple and convenient to manufacture. It is also lighter, smoother, and more aesthetically pleasing. During receiving, materials slide smoothly without jamming, improving work efficiency and accelerating the overall work progress of the saw.
[0004] However, the above technical solution has certain shortcomings. When the receiving table is close to the cutting end of the saw, some of the debris generated from cutting the pipe will enter the inclined surface of the receiving table along with the cut pipe. Since the cutting of metal will spray coolant, the debris will clump together due to the coolant and accumulate on the inclined surface of the receiving table. On the one hand, this will hinder the unloading of the cut pipe, and on the other hand, it will require manual cleaning of the receiving table, ultimately resulting in low efficiency in pipe cutting. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to provide a multi-hole bending receiving table for a CNC sawing machine, so as to solve the technical problem mentioned in the background that metal chips easily accumulate on the receiving table, affecting the unloading of the cut pipes.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a multi-hole bending receiving table for a CNC sawing machine, including a trapezoidal U-frame, characterized in that: multiple sets of rollers are assembled inside the trapezoidal U-frame, a trapezoidal plate is slidably provided inside the trapezoidal U-frame at the position of the outer wall of the curved surface of the multiple sets of rollers, a lead screw extending to the outside of the trapezoidal U-frame is rotatably provided on the side wall of the trapezoidal plate, and a threaded hole for the lead screw to pass through is opened on the outer wall of the trapezoidal U-frame;
[0007] The back of the trapezoidal U-frame is fixed with a positioning plate mounted on the saw. Inside the trapezoidal U-frame, a scraper is mounted below each set of rollers. The two ends of the scraper are slidably mounted on the inner wall of the trapezoidal U-frame. The bottom of the trapezoidal U-frame is provided with a drawer for collecting metal scraps. An elliptical ring is fixed to one end of the roller for driving the scraper to vibrate up and down.
[0008] In a preferred embodiment, a protective plate is fixed to the inclined top of the trapezoidal U-frame, a transverse groove is reserved at the top of the protective plate, and an indicator needle is provided at the top of the trapezoidal plate within the transverse groove.
[0009] In a preferred embodiment, a clearance groove is provided at the top of the trapezoidal U-frame, close to the rear surface, and sealing plates are fixed on both sides of the clearance groove on the inner wall of the trapezoidal U-frame.
[0010] In a preferred embodiment, a transmission belt is fitted on the outer wall of the other end of the multiple sets of rollers, and each set of rollers is equipped with a pulley that cooperates with the transmission belt on its outer wall.
[0011] In a preferred embodiment, the inner wall of the trapezoidal U-frame is provided with vertical stroke grooves at positions corresponding to the two ends of each set of scrapers. Slider blocks that are slidably disposed inside the stroke grooves are fixed at both ends of the scrapers, and springs for resetting the sliders are fixed inside the stroke grooves.
[0012] In a preferred embodiment, a handle fixed to the end of the roller is provided on the side wall and front surface of the trapezoidal U-frame, and a channel for the handle to rotate is provided on the outer wall of the trapezoidal U-frame.
[0013] In a preferred embodiment, the trapezoidal U-frame has a pre-reserved transmission groove for the rotation of both ends of the roller.
[0014] The multi-hole bending receiving table for a CNC saw provided by this utility model has the following beneficial effects by adopting the above structure:
[0015] (1) The scraper is driven to vibrate up and down by the elliptical ring set at the end of the roller, which can scrape off the metal debris attached to the roller and the inclined surface of the receiving table in real time during the pipe cutting process, avoiding the accumulation of debris due to coolant. Combined with the drawer to collect the debris, the frequency of manual cleaning is significantly reduced, ensuring smooth pipe feeding and improving cutting efficiency;
[0016] (2) The trapezoidal plate is connected to the threaded hole of the trapezoidal U-frame by the screw, and the sliding position of the trapezoidal plate on the roller can be adjusted manually or electrically to dynamically change the tilt angle of the receiving platform, adapt to the material feeding requirements of pipes of different lengths and weights, and avoid the problem of jamming or uneven sliding speed caused by the fixed tilt angle.

Detailed Implementation
[0027] A multi-hole bending receiving table for a CNC sawing machine, such as Figures 1 to 8 As shown, it includes a trapezoidal U-frame 100, with multiple sets of rollers 130 assembled inside the trapezoidal U-frame 100. A trapezoidal plate 110 is slidably provided inside the trapezoidal U-frame 100 on the outer wall of the curved surface of the multiple sets of rollers 130. A lead screw 111 extending to the outside of the trapezoidal U-frame 100 is rotatably provided on the outer wall of the trapezoidal U-frame 100. A threaded hole for the lead screw 111 to fit on the outer wall of the trapezoidal U-frame 100 is provided on the outer wall of the trapezoidal U-frame 100.
[0028] The rear surface of the trapezoidal U-frame 100 is fixed with a positioning plate 150 mounted on the saw. Each set of rollers 130 in the trapezoidal U-frame 100 is equipped with a scraper 170. The two ends of the scraper 170 are slidably disposed on the inner wall of the trapezoidal U-frame 100. The inner bottom of the trapezoidal U-frame 100 is provided with a drawer 140 for collecting metal scraps. An elliptical ring 132 for driving the scraper 170 to vibrate up and down is fixed on the outer wall of the roller 130 close to the end face.
[0029] The inner wall of the trapezoidal U-frame 100 is provided with stroke grooves 101 at the corresponding positions of the two ends of each set of scraper strips 170. The two ends of the scraper strips 170 are fixed with sliders 171 that are slidably disposed inside the stroke grooves 101. A spring 172 for resetting the sliders 171 is fixed inside the stroke grooves 101.
[0030] A handle is provided on the side wall and front surface of the trapezoidal U-frame 100 and fixed to the end of the roller 130. A channel for the handle to rotate is opened on the outer wall of the trapezoidal U-frame 100.
[0031] The saw cuts multiple stacked pipes. The cut pipes fall into the trapezoidal U-frame 100 and roll or slide down along multiple inclined rollers 130. The operator can rotate the lead screw 111 according to the size of the pipe or the size of the stacked pipes to make the trapezoidal plate 110 slide in the middle, controlling the space between the trapezoidal U-frame 100 and the trapezoidal plate 110, so that it can be used for a wide range of pipe models. The debris that enters with the pipes will fall into the drawer below through the space between the two rollers 130. When the pipes slide down, the drive will drive the rollers 130 to rotate slightly, which will also cause some debris to fall down.
[0032] When manually cleaning the debris on the receiving platform, an external force can be applied to the roller 130 to rotate it. Multiple rollers 130 will rotate synchronously. The debris attached to the outer wall of the roller 130 will be dislodged by the scraper 170, allowing the debris to slide across the outer wall of the scraper 170 and eventually fall into the drawer 140. At this time, when the roller 130 rotates, the elliptical ring 132 at the end will intermittently squeeze the slider 171, causing the slider 171 to lower and compress the spring 172. When the elliptical ring 132 no longer applies pressure to the slider 171, the spring 172 causes the scraper 171 to rise and return to its original position via the slider, causing the scraper 170 to vibrate, so that the debris attached to its outer wall completely falls into the drawer. Finally, the drawer can be manually pulled to the outside of the trapezoidal U-frame 100 to complete the quick cleaning of debris.
[0033] Combined with appendix Figure 1 , 2 A protective plate 120 is fixed to the inclined top of the trapezoidal U-frame 100. A horizontal slot is reserved at the top of the protective plate 120. An indicator needle that is slidably disposed in the horizontal slot is fixed to the top of the trapezoidal plate 110.
[0034] It serves to restrain the cut pipes, preventing them from flying and injuring people due to their light weight. At the same time, by observing the position of the indicator needle, one can determine the size of the space formed by the trapezoidal plate 110 and the trapezoidal U-frame, and whether it is suitable for cutting the pipes.
[0035] like Figure 2 In the middle, a clearance groove 161 is provided at the top of the trapezoidal U-frame 100 close to the rear surface, and sealing plates 160 are fixed on both sides of the clearance groove 161 on the inner wall of the trapezoidal U-frame 100.
[0036] The clearance groove 161 provides cutting space for the saw blade on the sawing machine, ensuring that the pipe is cut, and at the same time, it supports the pipe so that it can be accurately fed onto the roller 130 for unloading.
[0037] like Figure 4 In the middle, the outer wall of the other end of the multiple sets of rollers 130 is fitted with a transmission belt 131, and the outer wall of each set of rollers 130 is equipped with a pulley that is fitted with the transmission belt 131.
[0038] This allows multiple sets of rollers 130 to be synchronously driven by the transmission belt 131, while the pulleys act as a constraint between the rollers 130 and the transmission belt 131, preventing slippage from affecting the subsequent debris clearing effect.
[0039] The trapezoidal U-frame 100 has a transmission groove reserved inside for the two ends of the roller 130 to rotate.
[0040] In use, the saw cuts multiple stacked pipes. The cut pipes fall into the trapezoidal U-frame 100 and roll or slide down along multiple inclined rollers 130. The operator can rotate the lead screw 111 according to the size of the pipe or the size of the stacked pipes to make the trapezoidal plate 110 slide in the middle, controlling the space between the trapezoidal U-frame 100 and the trapezoidal plate 110, so that it can be used for a wide range of pipe models. The debris that enters with the pipes will fall into the drawer below through the space between the two rollers 130. When the pipes slide down, the drive will drive the rollers 130 to rotate slightly, which will also cause some debris to fall down.
[0041] When manually cleaning the debris on the receiving platform, an external force can be applied to the roller 130 to rotate it. Multiple rollers 130 will rotate synchronously. The debris attached to the outer wall of the roller 130 will be dislodged by the scraper 170, allowing the debris to slide across the outer wall of the scraper 170 and eventually fall into the drawer 140. At this time, when the roller 130 rotates, the elliptical ring 132 at the end will intermittently squeeze the slider 171, causing the slider 171 to lower and compress the spring 172. When the elliptical ring 132 no longer applies pressure to the slider 171, the spring 172 causes the scraper 171 to rise and return to its original position via the slider, causing the scraper 170 to vibrate, so that the debris attached to its outer wall completely falls into the drawer. Finally, the drawer can be manually pulled to the outside of the trapezoidal U-frame 100 to complete the quick cleaning of debris.
