[0021] Embodiment 1:

[0022] A cutting die for processing hardware parts in a preferred embodiment of the present utility model, as Figure 1-2As shown in the figure, it includes a lower die 10 and an upper die 20. The lower die 10 is provided with a mounting seat 11 for horizontally placing the workpiece 01, and a positioning component for positioning the workpiece 01 on the mounting seat 11. In this embodiment, the mounting seat 11 has a strip-shaped structure. The upper surface of the mounting seat 11 is the workpiece placement position. A plurality of cutting edge grooves 111 are arranged on the mounting seat 11 along its length direction. The cutting edge grooves 111 penetrate through the left and right side surfaces of the mounting seat 11. A receiving groove 112 is provided between two adjacent cutting edge grooves 111 on the mounting seat 11. A stripping component 12 for separating the workpiece 01 from the workpiece placement position is arranged in the receiving groove 112. A tool holder 21 corresponding to the mounting seat 11 up and down is movably arranged on the upper die 20, and a lifting component 22 for driving the tool holder 21 to longitudinally approach or move away from the mounting seat 11. In this embodiment, the lifting component 22 can be a screw module or a lifting cylinder and other structures in the prior art. A plurality of cutting tools 23 corresponding to and adapted to the cutting edge grooves 111 are fixedly arranged on the tool holder 21. The lower end of the cutting tool 23 has a conical structure, which is convenient for cutting.

[0023] The cutting die for processing hardware parts is ingeniously designed. When in use, first place the workpiece to be cut along the length direction of the mounting seat on the workpiece placement position. Then, through the positioning component, the workpiece to be cut on the mounting seat is positioned left and right, which can ensure that the workpiece to be cut is in the preset position on the mounting seat, and the positioning is accurate to ensure the accuracy of subsequent cutting. During cutting, the lifting component drives the tool holder and a plurality of cutting tools to move downward, and the workpiece to be cut on the mounting seat is segmented by a plurality of cutting tools at the same time, which can divide the workpiece to be cut into several segments at one time, with high cutting efficiency, and can further reduce material waste and labor costs.

[0024] Further, the positioning component includes a push plate 13 movably arranged on the left side of the mounting seat 11, a first driving cylinder 14 for driving the push plate 13 to move horizontally, a baffle 15 movably arranged on the right side of the mounting seat 11, and a second driving cylinder 16 for driving the baffle 15 to move longitudinally. Before the cutting die cuts, the first driving cylinder drives the baffle 15 to move upward until its upper surface is higher than the upper surface of the mounting seat to initially position the workpiece 01 to prevent it from shifting out of the workpiece placement position to the right. The push plate 13 pushes the workpiece 01 towards the baffle 15 until the workpiece 01 abuts against the baffle 15. Through the mutual cooperation of the push plate and the baffle, the position of the workpiece on the mounting seat can be adjusted, and the positioning property is good.

[0025] Further, the positioning component also has the function of pushing the material. After the cutting die cuts, the second driving cylinder 16 drives the baffle 15 to move downward to the lower part of the workpiece 01, and the first driving cylinder 14 drives the push plate 13 to move the workpiece 01 until the workpiece 01 on the mounting seat 11 is pushed out of the workpiece placement position. Through the mutual cooperation of the push plate and the baffle, the cut workpiece can be pushed out of the mounting seat, which is convenient for the workpiece to be cut to be cut again.

[0026] Optionally, a storage basket 17 is detachably installed on one side of the baffle 15 on the lower die 10; the upper surface of the storage basket 17 is not higher than the surface of the workpiece placement position; after the baffle moves down, the push plate can directly push the cut workpiece into the storage basket, saving the material receiving process and making the process coherent.

[0027] Furthermore, the multiple cutting edge grooves 111 and the multiple receiving grooves 112 are uniformly distributed in sequence along the length direction of the mounting base 11, which can improve the quality and consistency of the product.

[0028] In this embodiment, the stripping component 12 includes a thimble 121 movably disposed in the receiving groove 112 with the needle head facing the direction of the upper die 20, and a return spring 122 that provides an elastic return force for the thimble 121; one end of the return spring 122 is fixedly connected to the lower die 10 through a stop block 123, and the other end is fixedly connected to the thimble 121. When the mounting base and the tool holder are closed, the thimble moves into the receiving groove, and the return spring is in a compressed state; when the mounting base and the tool holder are opened, the return spring resets and drives the thimble to move outward in the direction of the upper die, so as to separate the workpiece on the workpiece placement position from the upper surface of the mounting base, facilitating subsequent stripping.

[0029] Embodiment 2

[0030] This embodiment provides a cutting die for processing hardware parts. The same parts as those in Embodiment 1 will not be described in detail. The differences are as Figure 3 shown. The positioning component includes a left clamping plate 31 movably disposed on the left side of the mounting base 11, a third driving cylinder 32 that drives the left clamping plate 31 to move horizontally closer to or away from the workpiece placement position, a right clamping plate 33 movably disposed on the right side of the mounting base 11 and corresponding to the left clamping plate 31, and a fourth driving cylinder 34 that drives the right clamping plate 33 to move horizontally closer to or away from the workpiece placement position; before the cutting die cuts, the left clamping plate 31 and the right clamping plate 33 move closer to each other synchronously until they clamp and position the workpiece 01, with precise positioning, facilitating subsequent cutting processing.

[0031] It should be understood that for those of ordinary skill in the art, improvements or changes can be made according to the above description, and all such improvements and changes should fall within the protection scope of the appended claims of the present invention.
