DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0027] Embodiment 1:

[0028] The multifunctional shearing machine comprises a workbench 1, a supporting leg 2 is installed at the bottom of the workbench 1, a cutting structure is installed in the middle of the top surface of the workbench 1, a protective structure is installed at the bottom of the cutting structure, and a feeding structure is installed in the middle of the top surface of the workbench 1 near the right end.

[0029] The feeding structure includes an adjustment unit and a feeding unit. The adjustment unit includes a conveying frame 301. A threaded rod 302 is installed in the middle of the top surface of the conveying frame 301. A turntable 303 is installed on the top of the threaded rod 302. A lifting frame 304 is connected to the outer surface of the threaded rod 302 near the bottom. The feeding unit includes an active roller 305. An asynchronous motor 306 is connected to one end of the back of the active roller 305. A clamping plate 307 is installed on the bottom surface of the asynchronous motor 306. A driven roller 308 is arranged at the bottom of the active roller 305.

[0030] The bottom end of the conveying frame 301 is fixedly connected to the top surface of the workbench 1, the front and back sides of the lifting frame 304 are slidably connected to the outer surface of the conveying frame 301, the front and back sides of the outer surface of the active roller 305 are connected to the bottom of the lifting frame 304 through bearings, the back side end of the active roller 305 is slidably connected to the inside of a slide groove opened in the middle of the back side of the conveying frame 301, the front end of the clamping plate 307 is slidably connected to the back side end of the conveying frame 301, and the driven roller 308 is installed inside a rectangular groove opened in the middle of the top side of the workbench 1 near the right end.

[0031] By setting up the feeding structure, utilizing the threaded connection between the threaded rod 302 and the threaded cylinder in the middle of the top surface of the lifting frame 304, and the sliding connection limit between the lifting frame 304 and the conveying frame 301, the lifting frame 304 can drive the active roller 305 to adjust the height, so that it can be suitable for feeding workpieces of various thickness sizes.

[0032] When the feeding structure is used to transport the workpiece, the threaded rod 302 is driven to rotate by rotating the turntable 303, and the threaded connection between the threaded rod 302 and the threaded tube installed in the middle of the top surface of the lifting frame 304, and the limited sliding connection between the front and back of the lifting frame 304 and the conveying frame 301 can be used to adjust the lifting height of the lifting frame 304. The lifting frame 304 drives the active roller 305 to adjust its height while lifting. The sliding connection inside the slide groove drives the asynchronous motor 306 and the card plate 307 to rise and fall. During the lifting process, the card plate 307 uses the U-shaped groove opened in the middle of the front side of the card plate 307 to slide and connect with the back side of the conveying frame 301, so as to limit the position, without affecting the output end of the asynchronous motor 306 to drive the active roller 305 to rotate. The active roller 305 and the driven roller 308 are abutted against the top and bottom surfaces of the workpiece. At the same time, the asynchronous motor 306 drives the active roller 305 to rotate, thereby realizing the feeding of the workpiece.

[0033] Embodiment 2:

[0034] On the basis of the first embodiment, the cutting structure includes a cutting frame 101, a hydraulic cylinder 102 is installed at one end of the middle of the top surface of the cutting frame 101 near the front and back, a mounting plate 103 is installed at the output end of the hydraulic cylinder 102, an upper knife 104 is installed on the bottom surface of the mounting plate 103, and a lower knife 105 is arranged on the bottom surface of the upper knife 104. The bottom surface of the cutting frame 101 is fixedly connected to the middle of the top surface of the workbench 1, the lower knife 105 is installed inside a rectangular through hole opened in the middle of the top surface of the workbench 1, and the right side of the upper knife 104 is slidably connected to the left side of the lower knife 105.

[0035] The protective structure includes a mounting box 201, a damping rod 202 is installed inside the mounting box 201, a buffer block 203 is installed on the top of the damping rod 202, and a buffer block 204 is arranged on the top of the buffer block 203. The top of the mounting box 201 is fixedly connected to the middle of the bottom surface of the workbench 1 near the front and back ends, the front end and the back end of the buffer block 1 203 are slidably connected to the inner wall of the rectangular through hole opened in the middle of the top surface of the workbench 1, and the buffer block 204 is installed on the right end of the bottom surface of the mounting plate 103.

[0036] By setting up the cutting structure and the protective structure, when the hydraulic cylinder 102 is started to drive the mounting plate 103 to move up and down, the upper knife 104 can be driven to move up and down synchronously, and cooperate with the lower knife 105 to complete the shearing of the workpiece. In the process of shearing, the buffer block 1 203 and the buffer block 204 are used, and the buffer block 1 203 and the damping rod 202 cooperate to buffer, which can effectively prevent the upper knife 104 from excessive movement and causing damage.

[0037] When the cutting structure is used to cut the workpiece, the mounting plate 103 and the upper knife 104 are driven downward by starting the hydraulic cylinder 102, and the sliding connection between the right side of the upper knife 104 and the left side of the lower knife 105 and the bottom bevel of the upper knife 104 are utilized to complete the shearing of the workpiece. During the cutting process, the upper knife 104 is utilized to squeeze the buffer block 1 203, thereby squeezing the damping rod 202, thereby buffering the movement of the upper knife 104. At the same time, the squeezing of the lower knife 105 and the buffer block 204 can be utilized to block and buffer their relative movement, thereby effectively preventing damage to the blade caused by excessive movement.
