Description

Technical Field

[0001] This utility model relates to the field of sheet metal shearing technology, and in particular to a sheet metal shearing and unloading machine. Background Technology

[0002] In the sheet metal processing industry, shearing sheet metal parts is a common production process. Generally, sheet metal shearing equipment is used to cut large sheet metal parts into smaller pieces, which are then manually removed from the shearing station and placed on a conveyor belt for further processing or transportation.

[0003] This operating method often requires operators to manually reach into the shearing station area or use simple tools (such as clamps) to remove the small pieces of workpiece that have been cut off. This operating method is not only inefficient and increases the processing time for a single workpiece, but also poses extremely high safety risks. Operators frequently entering this area to manually remove materials are highly susceptible to pinching, crushing, or even more serious personal injury accidents. Utility Model Content

[0004] Based on this, the present invention provides a sheet metal shearing and unloading machine with a simple structure and convenient use. The shearing drive cylinder drives the swing arm to drive the upper and lower blades to cooperate in shearing. The unloading drive motor drives the rubber wheel to rotate, and smoothly pushes the sheared small sheet metal parts out of the frame. The whole process does not require manual insertion into the shearing station to pick up the material, which not only improves work efficiency, but also greatly reduces the safety risk of personal injury accidents to the operators.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0014] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0016] Please see Figures 1 to 6 The sheet metal shearing and unloading machine according to one embodiment of the present utility model includes a supporting component 10 and a shearing and unloading component 20 installed in the supporting component 10.

[0017] The support assembly 10 includes a frame 11, a lower blade 12 fixedly installed inside the frame 11, a buffer plate 13 connected to one side of the lower blade 12, and a height limiting rod 14 installed on the side of the frame 11 near the buffer plate 13. The height limiting rod 14 is parallel and vertically spaced from the buffer plate 13, and the height of the height limiting rod 14 is greater than the height of the buffer plate 13.

[0018] The shearing and discharge assembly 20 includes a swing arm 21 hinged to one end of the lower blade 12, an upper blade 22 mounted on one side of the swing arm 21, a shearing drive cylinder 23 mounted on the top of the frame 11, multiple extension arms 24 evenly spaced on the side of the swing arm 21 opposite to the upper blade 22, rubber wheels 25 rotatably connected to the ends of each extension arm 24, and a discharge drive motor 26 mounted on each extension arm 24. The discharge drive motor 26 is used to connect to the rubber wheels 25 to drive the rubber wheels 25 to rotate. The piston rod of the shearing drive cylinder 23 slides downwards to connect to the free end of the swing arm 21. When the piston rod of the shearing drive cylinder 23 moves downwards, it drives the swing arm 21 to swing, thereby causing the upper blade 22 and the lower blade 12 to form a shearing effect.

[0019] In this embodiment, the upper blade 22 and the lower blade 12 are symmetrically distributed along the same plane, with their cutting edges facing opposite directions, ensuring that when they are closed, their cutting edges intersect to form a shearing surface.

[0020] In this embodiment, as Figure 5As shown, the piston rod of the shearing drive cylinder 23 is connected to a mating sleeve 230, and the top of the free end of the swing arm 21 is connected to a mating piece 211. The mating piece 211 has an inclined through groove 212. The mating piece 211 is fitted into the mating sleeve 230, and the mating sleeve 230 passes through the through groove 212 through a pin, thereby realizing a sliding groove connection between the piston rod of the shearing drive cylinder 23 and the free end of the swing arm 21.

[0021] In practical applications, such as Figure 6 As shown, the entire shearing and feeding assembly 20 is located directly above the buffer plate 13. When the upper blade 22 falls into position, it works together with the lower blade 12 to shear the sheet metal material into small pieces. These small pieces fall onto the buffer plate 13 under their own weight, at which point the rubber roller 25 comes into contact with them. The feeding drive motor 26 drives the rubber roller 25 to rotate, smoothly pushing the small pieces of sheet metal out of the frame 11 through the gap between the height limit bar 14 and the buffer plate 13. This design effectively prevents the small pieces of sheet metal from jumping or bouncing during feeding, ensuring smooth and stable feeding.

[0022] In this embodiment, a rotating shaft 240 is rotatably connected to the end of the extension arm 24. One end of the rotating shaft 240 is coaxially connected to the rubber wheel 25, and the other end of the rotating shaft 240 is coaxially connected to a driven gear (not shown). The rotor of the discharge drive motor 26 is coaxially connected to a driving gear (not shown). The driving gear and the driven gear are sleeved by a synchronous belt 27 to realize the power connection between the discharge drive motor 26 and the rubber wheel 25.

[0023] The above-mentioned sheet metal shearing and unloading machine has a simple structure and is easy to use. The shearing drive cylinder 23 drives the swing arm 21 to drive the upper blade 22 and the lower blade 12 to cooperate in shearing. The unloading drive motor 26 drives the rubber wheel 25 to rotate, and smoothly pushes the sheared small sheet metal parts out of the frame 11. The whole process does not require manual insertion into the shearing station to pick up the material, which not only improves work efficiency, but also greatly reduces the safety risk of personal injury accidents to the operators.

[0024] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0025] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
