Description

Technical Field

[0001] This utility model relates to the field of CNC hydraulic shearing machine technology, and in particular to a CNC hydraulic shearing machine with inlet protection. Background Technology

[0002] A shearing machine is a type of machine used for shearing metal sheets. It belongs to the category of forging and pressing machinery and is widely used in many industries such as machinery manufacturing, automobiles, shipbuilding, aerospace, and construction. Its working principle is to apply shearing force to the material through mechanical devices or hydraulic systems. When the shearing stress exceeds the shear strength of the material, the material is cut off, thereby achieving the purpose of separating the material.

[0003] In some existing hydraulic shearing machines, when feeding materials, the operator needs to gradually push the metal plate into the hydraulic shearing machine. There is a possibility that the plate may be pushed too deep and there is not enough time to react, which may easily cut the hand.

[0004] An existing patent (publication number: CN219274611U) discloses a hydraulic shearing machine with entrance protection. Through the coordinated use of the hydraulic shearing machine body, ear plate, mounting box, motor, rotating rod, conveying roller, fixed plate, slide rod, threaded rod, lifting block, right-angle connecting plate, rotating rod and positioning roller, it is convenient to convey metal sheets to the entrance of the hydraulic shearing machine body for shearing without manual pushing. On the one hand, it saves the labor intensity of the user and has a high degree of automation. On the other hand, it effectively prevents the worker from being injured by manually pushing the metal sheet, thus increasing the protective function and safety of the hydraulic shearing machine.

[0005] To address the aforementioned issues, while existing patents offer solutions that can automatically transport the sheet material using components such as motors, avoiding the potential dangers of manual pushing, the sheet material may become skewed if no limiting devices are installed on both sides during use. This results in the slit line of the sheet material becoming oblique after entering the shearing machine, rendering the sheet material unusable. Summary of the Invention

[0006] The purpose of this utility model is to provide a CNC hydraulic shearing machine with entrance protection, which can clamp and limit the plate on both sides by sliding the clamping plate along the first threaded rod and cooperating with the telescopic plate and the slider to ensure that the plate is in a regular state and maintains stability during the feeding process, while avoiding left and right tilting and deviation, which would affect the cutting surface of the plate and cause the cutting surface to tilt. This solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a CNC hydraulic shearing machine with inlet protection, comprising a shearing machine body, wherein an inlet is provided on the axial outer wall of the shearing machine body, and a blade groove is provided on one side of the inlet inside the shearing machine body, and a sliding groove is provided on the other side of the inlet on the axial outer wall of the shearing machine body, and a clamping mechanism is provided inside the sliding groove.

[0008] The clamping mechanism includes a first motor, which is embedded in one side of the outer wall of the shearing machine body. A first threaded rod is fixedly installed at the power output end of the first motor. A clamping plate is slidably connected to the outer wall of one end of the first threaded rod that passes through the sliding groove. A placement groove is opened on the outer wall of the clamping plate. A slider is slidably connected inside the placement groove. A telescopic plate is fixedly installed at one end of the slider that passes through the placement groove.

[0009] Preferably, a second threaded rod protrudes from the inner wall of one end of the slider inside the clamping plate, and the end of the second threaded rod protruding from the clamping plate is fixedly installed at the power output end of the second motor.

[0010] Preferably, a support plate is fixedly installed at the front end of the shearing machine body, and a support roller is rotatably connected between the two support plates.

[0011] Preferably, a connecting block is fixedly installed above the material inlet on the outer wall of the shearing machine body, and a pressing mechanism is provided at the bottom end of the connecting block.

[0012] Preferably, the pressing mechanism includes a fixing plate, which is fixedly installed above the mounting groove on the outer wall of the clamping plate, and a protruding plate extends from the end of the fixing plate away from the clamping plate. A slot is provided at the bottom of the interior of the fixing plate, and a locking block is slidably connected inside the slot.

[0013] Preferably, a connecting frame is fixedly installed at one end of the card block that protrudes from the fixing plate, and an abutting roller is rotatably connected between the two axial ends of the bottom end of the connecting frame.

[0014] Preferably, a connecting rod is fixedly installed on one side of the top locking block of the connecting frame, a sleeve is embedded inside the through plate at the position corresponding to the connecting rod, a limiting plate is fixedly installed at one end of the connecting rod that passes through the sleeve, and a spring is fixedly installed between the limiting plate and the sleeve.

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

[0016] 1. This utility model uses a clamping plate that slides along the first threaded rod and works in conjunction with a telescopic plate and a slider to slide stably, thereby clamping and limiting the plate on both sides. This ensures that the plate is in a regular state and maintains stability during the feeding process, while avoiding left and right tilting or offset, which would affect the cutting surface of the plate and cause the cutting surface to tilt, resulting in the plate's size and specifications not meeting the requirements, thus causing waste.

[0017] 2. The connecting frame of this utility model drives the abutment roller, which presses the plate during the conveying process under the elastic push of the spring. First, it presses the plate from above to maintain the stability of the plate during the conveying process and prevents it from tilting. At the same time, it prevents excessive shaking after the cutting force. With the cooperation of the locking block and the locking groove, the connecting frame can drive the abutment roller to press at the center line of the plate to prevent the deviation from affecting the stability of the downward pressure.

[0027] 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.

[0028] This utility model provides a technical solution:

[0029] Please see Figures 1 to 3A CNC hydraulic shearing machine with inlet protection includes a shearing machine body 1. An inlet 2 is formed on the axial outer wall of the shearing machine body 1. A blade groove 3 is formed on one side of the inlet 2 inside the shearing machine body 1, and a sliding groove 4 is formed on the other side of the inlet 2 on the axial outer wall of the shearing machine body 1. A clamping mechanism 5 is disposed inside the sliding groove 4. The clamping mechanism 5 includes a first motor 501, which is embedded in one side of the outer wall of the shearing machine body 1. A first threaded rod 502 is fixedly installed at the power output end of the first motor 501. A clamping plate 503 is slidably connected to the outer wall of one end of the first threaded rod 502 that passes through the sliding groove 4. A mounting groove 504 is formed on the outer wall of the clamping plate 503. A slider 505 is slidably connected inside the mounting groove 504. A telescopic mechanism is fixedly installed at one end of the slider 505 that extends out of the mounting groove 504. Plate 506; through the cooperation of the telescopic plate 506, the two clamping plates 503 can slide stably under the drive of the first threaded rod 502, clamping the plate and avoiding tilting or deviation that would affect the shearing effect; the slider 505 is located inside the clamping plate 503, and a second threaded rod 508 protrudes from the inner wall of one end of the slider 505. The end of the second threaded rod 508 protruding from the clamping plate 503 is fixedly installed at the power output end of the second motor 507; through the cooperation of the slider 505 and the second threaded rod 508, under the drive of the second motor 507, the telescopic plate 506 can push the plate for automatic feeding; a support plate 6 is fixedly installed at the front end of the shearing machine body 1, and a support roller 7 is rotatably connected between the two support plates 6; through the cooperation of the support plate 6 and the support roller 7, the bearing area of ​​the plate is increased, and the smoothness of the feeding process is improved.

[0030] By adopting the above technical solution, when the plate is placed on the shearing machine body 1, after one end is aligned with the feed port 2, the first motor 501 drives the bidirectional first threaded rod 502 to rotate. Then, through the matching bearings and nuts, the two clamping plates 503 can slide relative to each other and stably along the sliding groove 4, and limit the clamping of the plate from both sides. This avoids the plate from becoming skewed during the conveying process, and avoids the blade of the shearing machine body 1 from contacting the plate and causing tilting when cutting. After cutting, the shearing surface will be tilted, affecting the shearing effect of the plate. This will cause the plate to no longer be rectangular and the qualified size of the finished product to be in a state that cannot be recycled, resulting in waste of materials.

[0031] One end of the clamping plate 503 at the feed inlet 2 is a distance from the blade groove 3 to avoid affecting the falling path of the blade of the shearing machine body 1. When the two clamping plates 503 slide relative to each other, the sliders 505 fixed at both ends of the telescopic plate 506 pass through the corresponding placement grooves 504 into the clamping plates 503, which can maintain the stability of the sliding process of the two clamping plates 503. At the same time, one slider 505 slides along the placement groove 504 through the bearing and nut, driven by the second motor 507 and the second threaded rod 508, driving the other slider 505 to slide along the corresponding placement groove 504. The sliding slider 505 allows the telescopic plate 506 to push the plate through the feed inlet 2 for feeding, avoiding the danger of manual feeding where the hand goes too deep. Through the cooperation of the support plate 6 and the support roller 7, the plate can be fully supported and the smoothness of the feeding process can be improved.

[0032] Specifically, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, a connecting block 8 is fixedly installed above the feed inlet 2 on the outer wall of the shearing machine body 1. A pressing mechanism 9 is provided at the bottom end of the connecting block 8. The pressing mechanism 9 includes a fixed plate 901, which is fixedly installed above the mounting groove 504 on the outer wall of the clamping plate 503. A protruding plate 902 extends from one end of the fixed plate 901 away from the clamping plate 503. A slot 905 is provided at the bottom of the interior of the fixed plate 901, and a locking block 904 is slidably connected inside the slot 905. By sliding the locking block 904 along the slot 905, the connecting frame 903 can remain stable and avoid being affected when the fixed plate 901 and the protruding plate 902 slide relative to each other. One end of the locking block 904 extending out of the fixed plate 901 is fixedly installed. A connecting frame 903 is provided, with an abutment roller 906 rotatably connected between the two axial ends of the bottom end of the connecting frame 903. The abutment roller 906 presses against the top of the sheet material to prevent excessive warping of the sheet material during shearing. A connecting rod 907 is fixedly installed on one side of the top locking block 904 of the connecting frame 903. A sleeve 908 is embedded inside the sheet 902 at the position corresponding to the connecting rod 907. A limiting plate 909 is fixedly installed at one end of the connecting rod 907 that passes through the sleeve 908. A spring 910 is fixedly installed between the limiting plate 909 and the sleeve 908. Through the elastic contraction of the spring 910, the abutment roller 906 can press down on various sheet materials with similar thicknesses, improving applicability.

[0033] By adopting the above technical solution, the fixing plate 901 is first fixed by the connecting block 8 to prevent the clamping plate 503 from sliding relative to the through plate 902, thus avoiding displacement of the fixing plate 901 and affecting the position of the lower connecting frame 903 and the contact roller 906. When the fixing plate 901 slides along the connecting block 8, it slides along the locking block 904 fixed to the connecting frame 903 via the slot 905. The extension and retraction of the fixing plate 901 and the through plate 902 can reserve space for the displacement of the clamping plate 503, while avoiding affecting the connection. The positions of the connecting frame 903 and the abutment roller 906 are determined by the spring 910 inside the sleeve 908 embedded in the fixing plate 901, which elastically pushes the connecting rod 907, causing the connecting frame 903 to drive the abutment roller 906 to elastically press on the plate. This prevents the plate from tilting during transport and avoids excessive up-and-down shaking after being subjected to cutting force during cutting. At the same time, the abutment roller 906 improves the smoothness of pushing the plate. The limiting plate 909 allows the connecting rod 907 and the sleeve 908 to engage and prevent them from disengaging.

[0034] Working Principle: The shearing machine body 1 consists of multiple components including the machine body, transmission system, main control system, blade holder, and blades. It can shear sheet metal. This is a conventional technology and will not be described in detail. First, the sheet metal is inserted into the feed inlet 2. The first motor 501 drives the first threaded rod 502, which in turn drives the two clamping plates 503 to slide stably along the sliding groove 4, clamping and limiting the sheet metal from both sides to prevent skewing. The sliders 505 at both ends of the telescopic plate 506 pass through the corresponding placement grooves 504 of the clamping plates 503. Then, the second motor 507 drives the second threaded rod 508 to pass through one slider 505, thereby pushing the telescopic plate 506 to push the sheet metal for feeding. The other slider 505 slides stably along the corresponding placement groove 504. The telescopic plate 506 automatically extends and retracts with the adjustment of the clamping plates 503 to prevent leakage. In the current limited position, there is a gap between the clamping plate 503 and the blade groove 3, which reserves the cutting path of the blade of the shearing machine body 1. The support roller 7, which is rotatably connected by the support plate 6, facilitates the smoothness of the feeding process. The through plate 902, which is fixed by the connecting block 8, is slidably connected to the fixed plate 901, which is fixed by the clamping plate 503. The displacement of the clamping plate 503 allows the connecting frame 903 to slide stably along the slot 905 via the locking block 904, so as not to affect the connecting frame 903 driving the contact roller 906 to contact the plate. Through the elastic push of the spring 910, the connecting rod 907 passes through the sleeve 908, so that the contact roller 906 elastically presses the plate, which is suitable for plates of different thicknesses. At the same time, it avoids the plate from shaking excessively due to the influence of the upper and lower cutting during cutting. The limiting plate 909 prevents the connecting rod 907 from slipping off the sleeve 908.

[0035] 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.
