[0026] See attached Figure 1-5 As shown, an embodiment of the utility model is a sheet metal bending device, including a top plate 100, two groups of support plates 101 are fixedly installed on the bottom of the top plate 100, and fixed plates 102 are fixedly installed on the surfaces of the two groups of support plates 101. A mold 300 is arranged on the top of the fixed plate 102, and different molding grooves 308 are opened on the four sides of the mold 300. A fixed shaft 302 is fixedly inserted at the center of the mold 300, and flipping components for rotating the mold 300 are installed at both ends of the fixed shaft 302. The flipping component includes bearings 306 fixedly sleeved on both ends of the fixed shaft 302. Through the setting of the bearings 306, the friction force of the mold 300 during the rotation process is reduced, thereby facilitating the rotation of the staff.

[0027] The bearing 306 penetrates and is inserted into the surface of the guide plate 303. The surface of the fixed plate 102 is threadedly connected with a threaded column 305. One end of the threaded column 305 is rotatably connected to the bottom of the guide bar 105. The surface of the threaded column 305 below the fixed plate 102 is fixedly installed with a blocking column 304. The other end of the threaded column 305 is fixedly installed with a hand wheel 307. One end of the fixed shaft 302 is fixedly installed with a turntable 301. The bottom of the top plate 100 is fixedly installed with a hydraulic cylinder 106. The telescopic end of the hydraulic cylinder 106 is fixedly installed with a connecting plate 10 7. A sliding plate 201 capable of sliding up and down is slidably installed on the surface of the two groups of support plates 101. One end of the connecting plate 107 is fixedly connected to the surface of the sliding plate 201. A T-shaped slot 204 is provided at the bottom of the sliding plate 201. The inner cavity of the T-shaped slot 204 is horizontally slidably connected to a sheet metal bending knife 200. An L-shaped block 202 is fixedly installed on the surface of the sheet metal bending knife 200. A butterfly bolt 203 is penetrated and connected to the surface of the L-shaped block 202. One end of the butterfly bolt 203 penetrates the L-shaped block 202 and is threadedly connected to the surface of the sliding plate 201.

[0028] When in use, firstly, a plate to be bent is taken out and placed on the mold 300, and the hydraulic cylinder 106 is controlled to drive the sheet metal bending knife 200 to move downward to bend the plate.

[0029] When it is necessary to bend other shapes, unscrew the butterfly bolt 203 to release the restriction on the sheet metal bending knife 200, lift the sheet metal bending knife 200 to slide to one side, so as to disengage from the inner cavity of the T-shaped slide groove 204, and then select the sheet metal bending knife 200 according to the needs, and push the sheet metal bending knife 200 into the inner cavity of the T-shaped slide groove 204, use the butterfly bolt 203 to penetrate the L-shaped block 202 and threadedly connect the sliding plate 201 to fix the sheet metal bending knife 200, and at this time the staff turns the hand wheel 307 to drive the threaded column 305 to move upward, so as to fix the fixed shaft 302 and the mold 300. Lift upward and turn the hand wheel 307 to make the blocking column 304 on the surface of the threaded column 305 close to the bottom of the fixed plate 102, limit the upward distance of the threaded column 305, and ensure that the upward lifting distances of both ends are consistent, so that both ends of the mold 300 are in the same horizontal plane, which is convenient for the staff to rotate the mold 300. When the lifting of the mold 300 is completed, the staff turns the turntable 301, which is driven by the fixed shaft 302 to drive the mold 300 to rotate. The staff rotates the mold 300 to the required molding groove 308, and then loosens the threaded column 305 to lower the mold 300.

[0030] A wedge block 103 is fixedly installed at the bottom of the fixed plate 102, and a connecting block 104 is fixedly installed on the surface of the wedge block 103. The connecting block 104 is fixedly installed on the surfaces of the two groups of support plates 101. Guide strips 105 are fixedly installed on the surfaces of the two groups of support plates 101. The sliding plate 201 is slidably connected to the surface of the support plate 101 through the guide strips 105.

[0031] During specific use, the wedge block 103 transfers the force generated by the sheet metal bending knife 200 on the fixed plate 102 to the connecting plate 107, and then transfers it to the support plate 101 through the connecting block 104, thereby reducing the impact of the force generated by the downward movement of the sheet metal bending knife 200 on the fixed plate 102, thereby increasing the service life of the device; the guide bar 105 limits the sliding trajectory of the connecting plate 107, thereby avoiding the displacement of the sliding plate 201, causing the sheet metal bending knife 200 to be offset, thereby causing waste of materials, thereby improving the bending accuracy of the sheet metal bending knife 200.

[0032] The above shows and describes the basic principles of the present invention. The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only intended to illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions and improvements made within the spirit and scope of the present invention should be included in the protection scope of the present invention.
