Description
Technical Field
[0001] This utility model relates to the field of shearing machine technology, and in particular to a shearing machine with a plate limiting function. Background Technology
[0002] A shearing machine uses a moving upper blade and a fixed lower blade with a reasonable blade gap to apply shearing force to metal plates of various thicknesses, causing the plates to break and separate to the required dimensions. Its main function is in the metal processing industry, and it is a widely used shearing equipment in machining. It can shear steel plates of various thicknesses. Commonly used shearing machines are divided into three types: flat shearing, roller shearing, and vibrating shearing.
[0003] In the existing technology, the process of pushing the sheet material is carried out by manual pushing and adjusting the positioning structure to limit it. Dangerous situations may occur during the adjustment or pushing process.
[0004] An existing patent (publication number: CN220311893U) discloses a shearing machine with a limiting structure. The plate needs to be placed on the processing mesh first. Then, the cylinder is started. The cylinder pushes the pusher plate to move to both sides of the plate until its corners are clamped and fixed. Then, the linear screw electric guide rail is started. The drive sleeve outside the linear screw electric guide rail drives the pusher plate to move back and forth on the processing mesh. The pusher plate can push the plate to move below the shearing blade. The hydraulic cylinder pushes the shearing blade down, and the shearing blade cuts the plate.
[0005] To address the aforementioned issues, while existing patents have proposed solutions that can clamp and limit the sheet metal using components such as cylinders, in actual use, if the cutting end face is located at the clamping part of the pusher plate, it may come into contact with the shearing blade during the cutting process, thus affecting the cutting quality of the sheet metal. Summary of the Invention
[0006] The purpose of this utility model is to provide a shearing machine with a sheet metal limiting function, which can be adjusted according to the width of the sheet metal to improve applicability, while avoiding limiting and clamping the sheet metal in the shearing area of the shearing machine body, thus avoiding any impact on the shearing process, thereby solving the problems mentioned in the background art.

[0008] The limiting mechanism includes a motor, which is embedded in one side of the outer wall of the pushing platform. The power output end of the motor is connected to a bidirectional threaded rod.

A groove is provided at the top of the pushing platform corresponding to the position of the slider. A support shaft is fixed at the top of the slider, and a rotating block is rotatably connected to the outer wall of the end of the support shaft that passes through the groove. A limiting frame is fixed to the outer wall of the rotating block.
[0009] Preferably, the bidirectional threaded rod is threadedly connected to the slider, and the slider and the groove form a sliding structure.
[0010] Preferably, a mounting groove is provided on one side of the outer wall of the limiting frame, and an abutment roller is rotatably connected to the inner wall of the mounting groove.
[0011] Preferably, a connecting shaft is fixed to the top of the limiting frame, and a pressing mechanism is provided between the two limiting frames.
[0012] Preferably, the pressing mechanism includes a rotating plate, which is rotatably connected to the outer wall of the connecting shaft, and telescopic rods extend from the opposite outer walls of the two rotating plates.
[0013] Preferably, the pressing mechanism further includes a damping spring, which is embedded in the bottom end of the rotating plate, and the bottom end of the damping spring is connected to a mounting bracket, with a pressing roller rotatably connected between the two axes of the mounting bracket.
[0014] Preferably, the mounting bracket forms an elastic structure with the rotating plate via a damping spring, and the rotating plate forms a rotating structure with the connecting shaft.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. First, the support shaft, rotating block and limiting frame unfold to limit the sheet material from both sides. Then, the motor, bidirectional threaded rod, slider and slide groove cooperate to clamp and limit the sheet material.

[0026] 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.
[0027] This utility model provides a technical solution:
[0028] Please see Figures 1 to 4A shearing machine with sheet metal limiting function includes a shearing machine body 1. A feed inlet 2 is provided at the front end of the shearing machine body 1. A pushing platform 3 is located below the feed inlet 2 at the front end of the shearing machine body 1. A limiting mechanism 4 is provided on one side of the outer wall of the pushing platform 3. The limiting mechanism 4 includes a motor 401, which is embedded in one side of the outer wall of the pushing platform 3. A bidirectional threaded rod 402 is connected to the power output end of the motor 401. The bidirectional threaded rod 402 penetrates into the interior of the pushing platform 3, and a slider 40 is slidably connected to one end of its outer wall. 3. A slide groove 404 is provided at the top of the pusher platform 3 corresponding to the position of the slider 403. A support shaft 405 is fixed at the top of the slider 403. A rotating block 406 is rotatably connected to one end of the support shaft 405 that passes through the outer wall of the slide groove 404. A limit frame 407 is fixed to the outer wall of the rotating block 406. A bidirectional threaded rod 402 is threadedly connected to the slider 403. A sliding structure is formed between the slider 403 and the slide groove 404. A placement groove 5 is provided on one side of the outer wall of the limit frame 407. An abutment roller 6 is rotatably connected to the inner wall of the placement groove 5.
[0029] By adopting the above technical solution, the rotating block 406 is first rotated under the support of the support shaft 405 to unfold the limiting frame 407, which limits the plate material from both sides. Then, the motor 401 is started to drive the bidirectional threaded rod 402, which causes the two sliders 403 to drive the support shaft 405 to slide along the slide groove 404 on the pushing platform 3, thereby further clamping and limiting the plate material to prevent shaking or deviation during processing. At the same time, the limiting is performed outside the shearing machine body 1 to avoid affecting the internal shearing process. The limiting frame 407 is U-shaped to improve the limiting effect on the plate material. With the cooperation of the mounting groove 5 and the abutment roller 6, the smoothness of pushing the plate material into the feed port 2 of the shearing machine body 1 is improved. The limiting mechanism 4 can be folded when not in use by the support shaft 405 to avoid occupying space.
[0030] Specifically, such as Figure 1 and Figure 5 As shown, a connecting shaft 7 is fixed to the top of the limiting frame 407, and a pressing mechanism 8 is provided between the two limiting frames 407. The pressing mechanism 8 includes a rotating plate 801, which is rotatably connected to the outer wall of the connecting shaft 7. Telescopic rods 802 extend from the opposite outer walls of the two rotating plates 801. The pressing mechanism 8 also includes a damping spring 804, which is embedded in the bottom end of the rotating plate 801. A mounting frame 803 is connected to the bottom end of the damping spring 804. A pressing roller 805 is rotatably connected between the two axes of the mounting frame 803. The mounting frame 803 and the rotating plate 801 form an elastic structure through the damping spring 804, and the rotating plate 801 and the connecting shaft 7 form a rotating structure.
[0031] By adopting the above technical solution, when the limiting frame 407 rotates, the rotating plate 801 rotates via the connecting shaft 7 and unfolds via the telescopic rod 802, which can be adjusted according to the width of the plate, improving applicability. At the same time, the damping spring 804 elastically pushes the damping spring 804, causing the pressing roller 805 to abut against the top of the plate for limiting, avoiding shaking during processing. The damping spring 804 is also suitable for plates of different thicknesses, improving applicability and comprehensiveness.
[0032] Working principle: The sheet metal is supported by the pushing platform 3 and enters the shearing machine body 1 through the feed port 2 for processing. When it is necessary to unfold and limit the sheet metal, the rotating block 406 is rotated by the support shaft 405, so that the limiting frame 407 limits the sheet metal from both sides. At the same time, the motor 401 is started to drive the bidirectional threaded rod 402 to rotate, so that the two sliders 403 drive the corresponding support shaft 405 to slide along the slide groove 404 and allow the limiting frame 407 to fit and clamp the sheet metal to avoid shaking. At the same time, the clamping part is outside the shearing machine body 1 to avoid affecting the shearing process. The abutment roller 6 embedded in the mounting groove 5 improves the smoothness of the sheet metal pushing process. When the limiting frame 407 unfolds, the rotating plate 801 rotates through the connecting shaft 7 and unfolds through the telescopic rod 802. The rotating plate 801 elastically pushes the mounting frame 803 through the damping spring 804, so that the pressing roller 805 abuts against the sheet metal to avoid the sheet metal from fluctuating up and down during shearing.
[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.
