Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, and in particular to a CNC automatic fixed-length feeding shearing machine. Background Technology

[0002] Shearing machines are a type of forging and pressing machinery, mainly used in the metal processing industry. They use mechanical devices to apply a shearing force to materials. When the shearing stress exceeds the material's shear strength, the material is cut off, thus achieving the purpose of separation.

[0003] Shearing machines rely on manual pushing and feeding of sheet metal. Due to the lack of clamping and limiting mechanisms for the sheet metal, it is easy for the sheet metal to shift when being pushed.

[0004] A publicly available technical solution, CN214640550U, discloses a CNC automatic fixed-length feeding shearing machine, including a worktable and a limiting plate. The limiting plate has a placement groove that extends transversely through it. Side plates are located on the upper part of one longitudinal side of the worktable. A top plate is located on the side plates. The CNC shearing machine body is located at the bottom of the top plate, above the placement groove. Two support plates are provided, both positioned above the limiting plate and parallel to each other, located on one transverse side of the CNC shearing machine body. A sliding rod is transversely positioned between the two support plates. The machine uses a lever to push the sheet metal, ensuring high safety. The placement groove's inner wall limits the sheet metal, significantly improving the shearing quality.

[0005] In actual implementation, the above technical solution only limits the material by placing it on the inner wall of the groove. If the material size is much smaller than the inner wall size of the groove, the material will shift in the groove during feeding, affecting the shearing effect. Summary of the Invention

[0006] The purpose of this utility model is to provide a CNC automatic fixed-length feeding shearing machine that can synchronously limit the width of plates of different sizes during feeding, thereby preventing the plates from shifting during feeding and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a CNC automatic fixed-length feeding shearing machine, comprising a shearing machine body, wherein a liftable shearing blade is installed inside the shearing machine body, and a plate support base for supporting the plate is provided at the front end of the shearing machine body, wherein a clamping component for clamping the plate and a feeding component for feeding are installed on the plate support base.

[0008] The clamping assembly includes two sets of slidable clamping plates. Several rollers are rotatably mounted on the inner side of the clamping plates and are evenly distributed at equal intervals. A guide slider is fixedly provided at the bottom of the clamping plates, and a bidirectional lead screw is connected inside the guide slider through a lead screw sleeve.

[0009] Preferably, a guide groove is provided at the connection between the guide slider and the plate support base, and the two sets of clamping plates are symmetrically distributed about the vertical center line of the plate support base.

[0010] Preferably, one end of the bidirectional lead screw is fixedly provided with a transmission worm gear, and the other end of the bidirectional lead screw is installed inside the plate support base through a bearing.

[0011] Preferably, a transmission worm is meshed with one side of the transmission worm gear, and a power output end of a servo motor is fixedly provided at the end of the transmission worm.

[0012] Preferably, the feeding assembly includes a support plate fixed to the front end of the shearing machine body, and the support plate is located above the plate support base. A feeding motor is fixedly installed at the front end of the support plate by bolts.

[0013] Preferably, the power output end of the feeding motor is fixedly connected to a feeding screw, and a lever is connected to the outside of the feeding screw through a screw sleeve.

[0014] Preferably, a limiting plate is slidably installed on one side of the lever plate, and a clamping telescopic rod is fixedly provided on the top of the limiting plate. A fixing plate is fixedly provided on the top of the clamping telescopic rod, and a clamping spring is sleeved on the outside of the clamping telescopic rod. The fixing plate is vertically fixed on the lever plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the set clamping components, the distance between the two sets of clamping plates can be adjusted under the action of the bidirectional screw, so that the clamping plates can clamp plates of different widths.

[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] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A CNC automatic fixed-length feeding shearing machine includes a shearing machine body 1, a liftable shearing blade 2 installed inside the shearing machine body 1, a plate support base 5 for supporting the plate at the front end of the shearing machine body 1, and a clamping component 3 for clamping the plate and a feeding component 4 for feeding the plate installed on the plate support base 5.

[0028] The clamping assembly 3 includes two sets of slidable clamping plates 301. Several rollers 302 are rotatably mounted on the inner side of the clamping plates 301. A guide slider 303 is fixedly provided at the bottom of the clamping plate 301. A bidirectional lead screw 304 is connected to the inside of the guide slider 303 through a lead screw sleeve. A guide groove 305 is provided at the connection between the guide slider 303 and the plate support base 5. The two sets of clamping plates 301 are symmetrically distributed about the vertical center line of the plate support base 5. A transmission worm gear 308 is fixedly provided at one end of the bidirectional lead screw 304. The other end of the bidirectional lead screw 304 is installed inside the plate support base 5 through a bearing. A transmission worm 307 is meshed with one side of the transmission worm gear 308. The power output end of the servo motor 306 is fixedly provided at the end of the transmission worm 307.

[0029] By adopting the above technical solution, when the plate is placed between the two sets of clamping plates 301, the servo motor 306 can be started. The power output end of the servo motor 306 drives the transmission worm gear 307 to rotate, thereby causing the transmission worm wheel 308 on one side of the transmission worm gear 307 to rotate. The transmission worm wheel 308 then drives the bidirectional lead screw 304 to rotate, thereby causing the lead screw sleeve on the bidirectional lead screw 304 to drive the guide slider 303 to slide inside the guide groove 305. Since the two sets of clamping plates 301 are respectively installed at both ends of the bidirectional lead screw 304 through the lead screw sleeve, when the bidirectional lead screw 304... During rotation, the two sets of clamping plates 301 can slide in opposite directions via the lead screw sleeve, thereby adjusting the distance between the two sets of clamping plates 301. This allows the clamping plates 301 to clamp plates of different widths. At the same time, due to the unidirectional transmission of the transmission worm 307 and the transmission worm wheel 308, when the transmission worm 307 stops rotating, the transmission worm wheel 308 cannot rotate, thus limiting the position of the clamping plates 301. When the plate is being fed, the movement of the plate can drive the roller shaft 302 to rotate inside the clamping plates 301, thereby causing the plate to move on the surface of the roller shaft 302, thus realizing the feeding of the plate.

[0030] Specifically, such as Figure 4 As shown, the feeding assembly 4 includes a support plate 401 fixed to the front end of the shearing machine body 1, and the support plate 401 is located above the plate support base 5. The front end of the support plate 401 is fixedly installed with a feeding motor 402 by bolts. The power output end of the feeding motor 402 is fixedly connected to a feeding screw 408, and the outside of the feeding screw 408 is connected to a lever plate 403 through a screw sleeve. A limit plate 404 is slidably installed on one side of the lever plate 403, and a clamping telescopic rod 405 is fixedly installed on the top of the limit plate 404. A fixing plate 407 is fixedly installed on the top of the clamping telescopic rod 405, and a clamping spring 406 is sleeved on the outside of the clamping telescopic rod 405. The fixing plate 407 is vertically fixed on the lever plate 403.

[0031] By adopting the above technical solution, the feeding motor 402 is started, and the number of rotations of the feeding motor 402 can be adjusted by CNC technology, thereby adjusting the moving distance of the screw sleeve on the feeding screw 408, thus enabling length control of the feeding of the sheet material. When the length is consistent each time, fixed-length feeding is achieved. The power output end of the feeding screw 408 can drive the feeding screw 408 to rotate. Under the action of the screw sleeve, the deflector plate 403 slides below the support plate 401. The deflector plate 403 is in contact with the top of the sheet material support base 5. When the deflector plate 403 moves, the sheet material can be pushed to feed through the deflector plate 403. The sheet material enters between the shearing blades 2, and shearing is achieved as the shearing blades 2 descend. The limiting plate 404 can move upward by squeezing the telescopic rod 405 and the clamping spring 406. The limiting plate 404 can be adjusted according to the thickness of the sheet material.

[0032] Working principle: When the sheet material is placed between the two sets of clamping plates 301, the servo motor 306 can be started. The power output end of the servo motor 306 drives the transmission worm gear 307 to rotate, thereby causing the transmission worm wheel 308 on one side of the transmission worm gear 307 to rotate. The transmission worm wheel 308 then drives the bidirectional lead screw 304 to rotate, thereby causing the lead screw sleeve on the bidirectional lead screw 304 to drive the guide slider 303 to slide inside the guide groove 305, adjusting the distance between the two sets of clamping plates 301 so that the clamping plates 301 can clamp sheets of different widths. When the sheet material is fed, the movement of the sheet material can drive the roller 302 to move between the clamping plates 301. The internal rotation of the roller 302 causes the sheet material to move on the surface of the roller 302, thus realizing the feeding of the sheet material. The limiting plate 404 can move upward by squeezing the telescopic rod 405 and the clamping spring 406. The limiting plate 404 can be adjusted according to the thickness of the sheet material. The power output end of the feeding screw 408 can drive the feeding screw 408 to rotate. Under the action of the screw sleeve, the push plate 403 slides below the support plate 401. The push plate 403 is in contact with the top of the sheet material support base 5. When the push plate 403 moves, the sheet material can be pushed to feed the sheet material. The sheet material enters between the shearing blades 2, and the shearing is realized as the shearing blades 2 descend.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
