[0028] Example

[0029] Reference Figures 1-4 As an embodiment of the present invention, a positioning and protection device for a metal sheet shearing equipment is provided, comprising: a shearing unit 100 and a positioning unit 200.

[0030] The shearing unit 100 includes a frame 101, on which a gantry frame 102 is provided, and a shearing blade 103 is movably mounted on the gantry frame 102.

[0031] In another embodiment, the shearing unit 100 further includes a lifting hydraulic rod 104, which is fixedly mounted on the gantry frame 102. The output end of the lifting hydraulic rod 104 is fixedly connected to the shearing blade 103. A guide rod 105 is provided on the shearing blade 103, and the top end of the guide rod 105 penetrates through the gantry frame 102. The guide rod 105 is slidably connected to the gantry frame 102. The guide rod 105 penetrating through the gantry frame 102 ensures the stability of the shearing blade 103 during movement.

[0032] The positioning unit 200 includes a mounting frame 201, on which multiple power arms 202 are mounted. Two power arms 202 are symmetrically rotatably connected to the mounting frame 201. An angle adjustment and protection component is mounted on the end of each power arm 202 away from the mounting frame 201. An electro-hydraulic rod 203 is mounted on the frame 101. A synchronization plate 204 is fixedly connected to the output end of the electro-hydraulic rod 203. A slide rod 205 passes through the interior of the mounting frame 201. The mounting frame 201 and the slide rod 205 are slidably connected. One end of the slide rod 205 is fixedly connected to the synchronization rod. A connecting rod 206 is symmetrically rotatably connected to the other end of the slide rod 205. The connecting rod 206 is located between the slide rod 205 and the power arm 202. The end of the connecting rod 206 away from the slide rod 205 is rotatably connected to the power arm 202.

[0033] The extension and retraction of the electric hydraulic rod 203 drives the opening and closing of the power arm 202 and the angle adjustment and protection components to accommodate plates of different sizes.

[0034] In another embodiment, the angle adjustment and protection assembly includes a vertical rod 207, a limiting ring 208, and a connecting sleeve 209. The vertical rod 207 is rotatably connected to the end of the power arm 202 away from the mounting frame 201. The limiting ring 208 is fixedly sleeved on the vertical rod 207. The connecting sleeve 209 is sleeved on one end of the vertical rod 207. The connecting sleeve 209 and the limiting ring 208 are movably connected. A tension spring 210 is provided inside the connecting sleeve 209. A limiting piece 211 is fixedly connected to one end of the vertical rod 207 located inside the connecting sleeve 209. One end of the tension spring 210 is in contact with the limiting piece 211. A clamping member 212 is fixedly connected to the bottom of the connecting sleeve 209.

[0035] When the clamping member 212 contacts the metal plate, it will compress the tension spring 210, causing the vertical rod 207 to slide between the connecting sleeve 209 until the sliding key 213 enters the keyway 214, thereby fixing the angle between the connecting sleeve 209 and the vertical rod 207.

[0036] In another embodiment, a slide key 213 is fixedly connected to the vertical rod 207, and a keyway 214 adapted to the slide key 213 is provided on the connecting sleeve 209.

[0037] In another embodiment, the clamping member 212 includes a crossbar 215, the bottom of which is a clamping plate 216.

[0038] In another embodiment, the clamping member 212 includes a crossbar 215, the bottom of which is a clamping post 217.

[0039] During use, first, adjust the electric hydraulic rod 203 according to the size of the plate and preset the clamping position. Then, according to the size and shape of the plate, select to use the clamping plate 216 or the clamping post 217, and adjust the angle of the clamping part 212 as needed.

[0040] The metal sheet to be cut is placed on the lower clamping member 212. Then, the electric hydraulic rod 203 is activated, which extends to move the slide rod 205 horizontally. This causes the connecting rod 206 to shift at an angle, pulling the power arm 202 to rotate toward the slide rod 205. This causes the clamping member 212 to contact the metal sheet. When the clamping member 212 contacts the metal sheet, it will compress the tension spring 210, causing the vertical rod 207 to slide between the connecting sleeve 209 until the sliding key 213 enters the keyway 214. This fixes the angle between the connecting sleeve 209 and the vertical rod 207, thus preventing the angle of the metal sheet from shifting during the cutting process and completely fixing the metal sheet.

[0041] The lifting hydraulic rod 104 is activated, driving the shearing blade 103 to descend smoothly along the guide rod 105 for precise shearing of the sheet metal. After shearing is completed, the lifting hydraulic rod 104 rises back, and the electric hydraulic rod 203 reverses its movement, releasing the clamping member 212, thus completing one shearing operation.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
