Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, and in particular to a shearing machine with an anti-warping structure for sheet metal. Background Technology

[0002] A shearing machine is a machine tool specifically designed for cutting sheet metal. It primarily works by applying pressure to the sheet metal, causing it to break along a predetermined shear line, thus completing the cutting process. Shearing machines are generally suitable for cutting long and wide sheet metal and can process various metal materials, such as steel, stainless steel, and aluminum alloys.

[0003] In existing technologies, when shearing plates, the plates need to be aligned with the shearing blade. The plates need to be placed neatly and pushed towards the shearing blade. When aligning the plates manually, deviations may occur.

[0004] The existing patent (publication number: CN220862832U) discloses a limiting mechanism based on a shearing machine. The plate is placed on the placement component, and then the motor is turned on. The motor drives the bidirectional lead screw to rotate, and the two sets of clamping components move towards the plate at the same time. When the two connecting plates abut against the plate, the plate is aligned. Then, the two push cylinders are turned on, causing the second clamping plate to move downward, thereby clamping the plate. Then, the linear slide is moved forward to the appropriate position, and the plate is sheared by the shearing blade.

[0005] To address the aforementioned issues, existing patents propose solutions that use components such as motors to align the sheet metal. However, in actual use, the shearing machine applies significant cutting force, and the sheet metal being cut is typically long or wide. This can cause the sheet metal to warp due to excessive force or the size of the sheet, affecting the accuracy of the shearing. Furthermore, warping can easily injure workers. Summary of the Invention

[0006] The purpose of this utility model is to provide a shearing machine with an anti-warping structure for sheet metal, which can be adjusted according to the length and width of the sheet metal, thereby improving the overall versatility and applicability of the shearing machine and pressing the sheet metal to prevent warping due to vibration during cutting, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a shearing machine with an anti-warping structure for sheet metal, comprising a shearing machine body, wherein a feed inlet is provided above the front end of the shearing machine body, and an adjustment mechanism is provided on one side of the feed inlet at the front end of the shearing machine body;

[0008] The adjustment mechanism includes a support block, which is fixedly installed on one side of the feed inlet at the front end of the shearing machine body.

A damping spring is embedded at the top of the support frame, and a pressing plate is fixedly installed at one end of the damping spring. An abutment roller is rotatably connected between the two axes of the pressing plate.

[0009] Preferably, the pressing plate has a U-shaped structure, and the pressing plate and the abutting roller form a rotating structure.

[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 3A shearing machine with an anti-warping structure for sheet metal includes a shearing machine body 1. A feed inlet 2 is located at the upper front end of the shearing machine body 1. An adjustment mechanism 3 is located on one side of the feed inlet 2 at the front end of the shearing machine body 1. The adjustment mechanism 3 includes a support block 301, which is fixedly installed on one side of the feed inlet 2 at the front end of the shearing machine body 1. A through-rod 302 extends from the inside of the support block 301. A support block 303 is fixedly installed at one end of the through-rod 302 extending out of the support block 301. A hydraulic rod 304 is rotatably connected to the lower front end of the shearing machine body 1. Rotating components 305 are fixedly installed at both ends of the hydraulic rod 304. A stabilizing block 306 is movably connected to one end near the support block 303. A support frame 307 is fixedly installed above the support block 303. A damping spring 308 is embedded at the top of the support frame 307. A pressing plate 309 is fixedly installed at one end of the damping spring 308. An abutment roller 310 is rotatably connected between the two axes of the pressing plate 309. The pressing plate 309 has a U-shaped structure. The pressing plate 309 and the abutment roller 310 form a rotating structure. The hydraulic rod 304 forms a rotating structure with the support block 303 through the rotating assembly 305. The hydraulic rod 304 forms a rotating structure with the shearing machine body 1 through the rotating assembly 305.

[0028] By adopting the above technical solution, the hydraulic rod 304, the rotating component 305 and the stabilizing block 306 work together to stretch the support block 301, the through rod 302 and the support block 303, and automatically adjust according to the angle to avoid limit, thereby enabling it to bear plates of different lengths and widths and improving its applicability. When the plate is pushed, the damping spring 308 embedded in the support frame 307 fixed by the support block 303 elastically pushes the pressing plate 309 to press the contact roller 310 on the plate, thereby achieving a limit effect and preventing vibration during cutting and upward warping, thus keeping the plate stable and entering the shearing machine body 1 through the feed port 2.

[0029] Specifically, such as Figure 1 and Figure 4 As shown, a fixed frame 4 is fixedly installed above the feed inlet 2 at the front end of the shearing machine body 1. A limiting mechanism 5 is provided on one side of the fixed frame 4. The limiting mechanism 5 includes a motor 501, which is embedded in one side of the outer wall of the fixed frame 4. The power output end of the motor 501 is connected to a bidirectional threaded rod 502. A slider 503 is slidably connected to one end of the bidirectional threaded rod 502 that passes through the outer wall of the fixed frame 4. The limiting mechanism 5 also includes a connecting plate 504, which is fixedly installed at one end of the slider 503 that passes through the fixed frame 4. A limiting plate 505 is fixedly installed on one side of the outer wall of the connecting plate 504. A locking block 506 is fixedly installed at one end of the limiting plate 505 that passes through the pressing plate 309. The bidirectional threaded rod 502 is threadedly connected to the slider 503, and a sliding structure is formed between the slider 503 and the fixed frame 4.

[0030] By adopting the above technical solution, the motor 501 drives the bidirectional threaded rod 502, thereby allowing the two sliders 503 to slide stably relative to or away from each other along the fixed frame 4. The sliders 503 drive the connecting plate 504, thereby allowing the limiting plate 505 to limit and clamp the plate from both sides, maintaining the stability of the plate pushing process and preventing deviation. The locking block 506 fixed by the limiting plate 505 passes through the support block 301 and the corresponding pressing plate 309 of the fixed support frame 307. Under the limitation of the pressing plate 309, the limiting plate 505 maintains stable sliding.

[0031] Working principle: The rotating assembly 305 consists of a metal plate and a rotating rod. The hydraulic rod 304, with both ends connected to the shearing machine body 1 and the stabilizing block 306 via the rotating assembly 305, allows the stabilizing block 306 to drive the support block 303 to slide along the support block 301 via the through rod 302, thus adjusting according to the length of the sheet metal. The rotating assembly 305 automatically adjusts the angle of the hydraulic rod 304 to avoid limit stops. Both the support block 301 and the support block 303 are fixed with support frames 307. The damping spring 308 elastically pushes the pressing plate 309, allowing the contact roller 310 to slide against the plate to prevent it from warping upwards. By activating the motor 501 embedded in the fixing frame 4, the bidirectional threaded rod 502 pushes the two sliders 503 to slide relative to or away from each other, thereby driving the connecting plate 504 to slide. The limiting plate 505 fixed to the connecting plate 504 is slidably connected to the pressing plate 309 corresponding to the support block 301 via the locking block 506, thereby maintaining the stable sliding of the limiting plate 505 and thus limiting and clamping the plate from both sides.

[0032] 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.
