[0023] Please see Figures 1-4 This utility model provides a cutting and punching die, comprising:

[0024] The punching mechanism 100 includes a base 102, a fixing rod 103 fixedly connected to the base 102, a top plate 101 fixedly connected to the fixing rod 103, a lifting assembly 110 provided on the top plate 101, a punching assembly 120 provided on the lifting assembly 110, a cutter 104 provided on the lifting assembly 110, a fixing assembly 130 provided on the lifting assembly 110, and a pressing assembly 140 provided on the lifting assembly 110.

[0025] Specifically, the lifting component 110 can drive the punching component 120 and the cutter 104 to move up and down, facilitating punching and trimming of sheet metal parts; when punching and trimming sheet metal parts, the pressing component 140 can press and fix the sheet metal parts, thus facilitating the die to punch and trim the sheet metal parts; when the cutter is used for too long or is damaged, the fixing component 130 can be pulled to fix the cutter 104, reducing the cost of the device and improving the efficiency of the die.

[0026] Please see Figures 1-3The lifting assembly 110 includes a cylinder 110a, a lifting plate 110b, a first motor 110c, a first lead screw 110d, a slide rod 110e, and a sliding plate 110f.

The sliding plate 110f is threadedly connected to the first lead screw 110d. The punching assembly 120 includes a second motor 120a, a first bevel gear 120b, a second bevel gear 120c, a second lead screw 120d, a sliding block 120e, and a punching rod 120f. The second motor 120a is fixedly connected to the sliding plate 110f, the first bevel gear 120b is fixedly connected to the second motor 120a, the second bevel gear 120c is fixedly connected to the second lead screw 120d, the second lead screw 120d is rotatably connected to the inner groove of the sliding plate 110f, the first bevel gear 120b meshes with the second bevel gear 120c, the punching rod 120f is fixedly connected to the sliding block 120e, the sliding block 120e is threadedly connected to the second lead screw 120d, and the sliding block 120e is slidably connected to the inner groove of the sliding plate 110f.

[0027] Specifically, the first motor 110c can rotate the first lead screw 110d fixed to the first motor 110c, causing the sliding plate 110f on the first lead screw 110d to move. At the same time, the second motor 120a can rotate the second lead screw 120d, causing the sliding block 120e to move the punching rod 120f, thereby adjusting the position of the punching rod 120f to facilitate punching the sheet metal parts. Furthermore, the cylinder 110a can lift the lifting plate 110b, thereby driving the punching rod 120f and the cutter 104 to lift, facilitating the trimming and punching of the sheet metal parts.

[0028] Please see Figures 1-4The fixing assembly 130 includes a pull rod 130a, a first spring 130b, and a side plate 130c. A sliding groove 130d is provided on the lifting plate 110b. The side plate 130c is fixedly connected to both sides of the pull rod 130a. One end of the first spring 130b is fixedly connected to the side plate 130c, and the other end of the first spring 130b is fixedly connected to the inner wall of the sliding groove 130d. The pressing assembly 140 includes a pressing plate 140a, a second spring 140b, and a limiting plate 140c. A pressing groove 140d is provided at the bottom of the lifting plate 110b.

[0029] Specifically, when punching and trimming sheet metal parts, the pressing plate 140a can press and fix the sheet metal parts in advance, making it easier for the cutter 104 to trim the sheet metal parts. When the cutter 104 is damaged, the pull rod 130a can be pulled away from the fixing groove 104a, so that the cutter 104 can be removed from the mold for replacement, avoiding the need to replace the entire device and reducing the cost of the device.

[0030] Please see Figures 1-2 A lower mold 102a is fixedly connected to the base 102, a collection box 102b is provided on the base 102, a hole 102c is provided on the lower mold 102a, and a strainer 102d is provided on the base 102.

[0031] Specifically, during the punching and trimming of sheet metal parts, the waste material generated during punching can fall into the collection box 102b through the hole 102c on the lower die 102a. At the same time, some burrs generated during trimming can fall into the collection box 102b through the strainer 102d, facilitating centralized processing and preventing waste material from accumulating on the base 102, which would adversely affect the subsequent use of the die. Furthermore, by setting the hole 102c in an inverted funnel shape, the waste material generated after punching can fall into the collection box 102b, preventing blockage of the hole 102c and affecting the subsequent use of the device. By setting multiple holes 102c, the position of the punching rod 120f can be easily adjusted, enabling punching at different positions on the sheet metal parts.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
