Description

Technical Field

[0001] This utility model relates to the technical field of metal processing, and in particular to a metal sheet pressing and trimming machine. Background Technology

[0002] An edge trimming machine is an industrial device used to trim or cut the edges of materials. It is widely used in industries such as metal processing, plastics, paper, textiles, and printing. Its main functions are to remove excess burrs, slit rolls, or precisely trim the edges of products to meet dimensional, appearance, or subsequent processing requirements.

[0003] Current rounding and slicing machines can only perform single punching operations on metal sheets. The cut circular metal sheets still need to undergo secondary processing and trimming of their edges, making it impossible to perform integrated punching and trimming. In addition, current sheet cutting machines cannot automatically discharge the sheets after cutting. The metal sheets themselves are lightweight, making manual removal extremely inconvenient and greatly reducing work efficiency. Utility Model Content

[0028] The lifting mechanism 9 includes a screw 91, a first rotating motor 92, a moving block 93, and a support arm 94;

[0029] The screw 91 is provided above the base plate 1; the L-shaped support frame 3 is also provided with the first rotating motor 92; the output end of the first rotating motor 92 is connected to the screw 91; the moving block 93 is threadedly connected to the screw 91; the moving block 93 is fixedly connected to the support arm 94; the other end of the support arm 94 is fixedly connected to the bottom of the discharge plate 10.

[0030] The drive assembly 13 includes a motor mounting block 131, a second rotary motor 132, a drive gear 133, and a driven gear 134;

[0031] The base plate 1 is provided with the motor mounting block 131; the motor mounting block 131 is provided with the second rotating motor 132; the output shaft of the second rotating motor 132 is fixedly sleeved with the driving gear 133; the driving gear 133 meshes with the driven gear 134; the driven gear 134 is fixedly sleeved below the annular cylinder 11.

[0032] The chip suction assembly 14 includes a suction hole 141, a chip suction pipe 142, and a chip collection box 143;

[0034] Working principle: The metal sheet to be pressed and cut passes through the upper surface of the lower die. At this time, the drive cylinder 4 is opened, so that the connecting rod of the cylinder drives the upper die 6 to press down. The circular metal sheet is punched and cut above the discharge plate 10.

[0035] At this time, the second rotating motor 132 is turned on, causing the motor to rotate and drive the output shaft to rotate, thereby driving the driving gear 133 fixedly connected to the output shaft to start rotating. The rotating gear meshes with the driven gear 134 to drive the transmission, causing the annular cylinder 11 fixed to the driven gear 134 to rotate, driving the trimming blade 12 above the annular cylinder 11 to rotate, thereby trimming the edge of the punched metal sheet, thus realizing the integrated punching and trimming work; during the trimming process, by turning on the external fan, a negative pressure is generated in the cavity inside the lower die. At this time, the chips generated after trimming are sucked into the chip collection box 143 through the chip suction hole and then through the chip suction pipe 142.

[0036] After the punching and trimming work is completed, the first rotating motor 92 is turned on, causing the screw 91 to rotate, which in turn causes the moving block 93 to rise and fall, thereby moving the discharge plate 10 downward. Then, the metal sheet is blown out through the air blower 15 installed on the U-shaped frame 2.
