[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0030] Example 1

[0031] like Figure 1-4 As shown, a compatible punching die includes a base 1, a central die 2 and a pressure plate 3. The pressure plate 3 is symmetrically arranged on both sides of the central die 2. The pressure plate 3 is slidably connected to the base 1 and slides in a direction perpendicular to its own extension direction. The pressure plate 3 is provided with a punching punch 42 and a cutting punch 41.

[0032] The center mold 2 is slidably connected to the base 1 and can slide in a direction parallel to the extension direction of the pressure plate 3. There are two center molds 2, which are arranged opposite each other in a direction parallel to the pressure plate 3. There is a cutting punch between the two center molds 2. When the two center molds 2 are in the first position, the cutting die hole is opposite to the cutting punch 41. There is a punching die hole on the center mold 2. When the two center molds 2 are in the second position, the punching die hole is opposite to the punching punch 42.

[0033] This application sets up two movable central molds 2. When the two central molds 2 are in the first position, the pressure plate 3 slides, and the cutting punch 41 on the pressure plate 3 can cut the die material 5 to be punched into two parts. After the pressure plate 3 is moved away from the central mold 2, the central mold 2 is driven to slide, and the two parts of the die material 5 to be punched on the two central molds 2 can move to the second position along the two central molds 2 respectively. At this time, the pressure plate 3 is slid closer to the central mold 2 again, and the punching punch 42 is driven to perform the punching operation. This application integrates punching and cutting into one unit, reducing the labor intensity of manual handling and loading and unloading.

[0034] Example 2

[0035] The difference between this embodiment and Embodiment 1 is that: when the two central molds 2 are in the first position, the die material 5 is fitted around the outer periphery of the central mold 2; both sides of the central mold 2 are provided with positioning grooves 21 with top openings, and corresponding positioning blocks 51 are provided inside the die material 5. The positioning blocks 51 are inserted into the positioning grooves 21, and the positioning grooves 21 limit the horizontal and vertical positions of the positioning blocks 51; after the die material 5 is cut by the cutting punch 41, the two central molds 2 slide away from each other, and the die material 5 on the two central molds 2 can move synchronously to the second position with the two central molds 2. In this embodiment, the cutting punch 41 is located in the middle of the pressure plate 3, and the first position of the two central molds 2 is also in the middle; the second positions of the two central molds 2 are located on both sides.

[0036] A compatible punching die of this application further includes a first driving component, which drives the sliding of the center die 2. Each center die 2 corresponds to one first driving component. The first driving component includes a first telescopic cylinder 22, the fixed end of which is connected to the base 1, and the telescopic end is connected to the center die 2. The two center dies 2 are connected by a telescopic guide post 23, which guides the sliding direction of the center die 2.

[0037] In this embodiment, the base 1 is provided with a sliding groove 11, and the center mold 2 is slidably connected to the sliding groove 11 through a sliding block. The sliding groove 11 ensures the position and direction of the center mold 2 during the sliding process and avoids displacement.

[0038] The center mold 2 and the pressure plate 3 are positioned by positioning elements 6 to mark the cutting at the first position and the punching at the second position. The positioning elements include a set of positioning holes 61 on the center mold 2 and two sets of positioning posts 62 on each pressure plate 3 corresponding to each center mold 2. When the center mold 2 is in the first position, the set of positioning posts 62 on the pressure plate 3 is opposite to the positioning holes 61 on the center mold 2, thereby improving the accuracy and stability of the cutting process. When the center mold 2 is in the second position, the other set of positioning posts 62 on the pressure plate 3 is opposite to the positioning holes 61 on the center mold 2, thereby improving the accuracy and stability of the punching process.

[0039] In this embodiment, a material discharge hole is provided on the central mold 2. The material discharge hole is connected to the punching die hole. The waste material generated by punching enters the material discharge hole and is discharged by compressed air.

[0040] The base 1 has side plates 7 at both ends, which are connected to the pressure plate 3 via a telescopic mechanism. The telescopic mechanism includes a second telescopic cylinder 31, one end of which is connected to the side plate 7 and the other end to the pressure plate 3. When the second telescopic cylinder 31 extends, it can drive the pressure plate 3 to move closer to the central mold 2; when the second telescopic cylinder 31 retracts, it can drive the pressure plate 3 to move away from the central mold 2. To improve the sliding stability and accuracy of the pressure plate 3, guide telescopic rods 32 are provided between the pressure plates 3 on both sides of the central mold 2.

[0041] A tool holder 4 is detachably mounted on the side of the pressure plate 3 facing the central mold 2. A punching punch 42 and a cutting punch 41 are mounted on the tool holder 4, so that the tool holder 4 can be replaced when the punching punch 42 and the cutting punch 41 are worn.

[0042] A compatible punching die of this application also includes a controller, which controls the sliding of the pressure plate 3 and the center die 2. Initially, the first telescopic cylinder 22 is in the extended state, at which time the center die 2 is in the first position. After the material to be punched 5 is placed on the center die 2 along the opening, the controller can control the extension of the second telescopic cylinders 31 on both sides. The cutting punches 41 on both sides of the center die 2 move towards the center die 2 to enter the cutting punch hole for cutting action. After cutting is completed, the controller controls the second telescopic cylinders 31 to drive the pressure plate 3 and the cutting punches 41 to retract, and then controls the two first telescopic cylinders 22 to retract, and the two center dies 2 move to the second position. The controller controls the second telescopic cylinders 31 to extend again, and punching can then be performed.
