Description

Technical Field

[0001] The invention belongs to the technical field of punching machine dies, and in particular relates to a punching machine die. Background Art

[0002] The punch press die is an accessory corresponding to the punch press. The workpiece undergoes plastic deformation under the combined action of the punch press's punching pressure and the die's resistance to complete the processing process. The punch press die is an indispensable part of the stamping process. The accuracy of the punch press die largely determines the workpiece processing accuracy.

[0003] Although there are many kinds of punching dies at present, there are still some problems. For example, the current punching dies are often directly fixed on the punching machine when in use, and the stamping structure drives the die to perform the stamping operation. During stamping, the punching machine is also provided with a feeding structure to push the component to be stamped to the appropriate position. These structures are independent and each needs to be controlled by a numerical control unit when working. These numerical control units require other integrated equipment, resulting in a high overall operating cost of the stamping operation and inability to achieve mechanical linkage between the stamping die and the feeding structure. Summary of the invention

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0027] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] The embodiment of the present invention provides a punch die, such as Figure 1-4 As shown, it includes: a base 1, a gantry 2 and a molding mechanism 3;

[0029] The gantry 2 is fixed on the base 1, and the molding mechanism 3 is arranged between the base 1 and the gantry 2;

[0030] The molding mechanism 3 includes a stamping die 31, a cylinder 32, a molding seat 33 and a feeding unit. The fixed part of the cylinder 32 is connected to the top center of the gantry 2, the stamping die 31 is connected to the telescopic part of the cylinder 32, the molding seat 33 is fixed on the base 1, and the stamping die 31 is located above the molding seat 33;

[0031] The feeding unit part is connected with the stamping die 31 .

[0032] It should be noted that, since the existing punching machine mold is often directly fixed on the punching machine when in use, the stamping structure drives the mold to perform the stamping operation. During stamping, a feeding structure is also provided on the punching machine to push the component to be stamped to the appropriate position. These structures are independent and each needs to be controlled by a numerical control unit when working. These numerical control units require additional integrated equipment, resulting in a high overall operating cost of the stamping operation and the inability to mechanically link the stamping mold and the feeding structure. In order to solve this problem, a molding mechanism 3 is provided in the present scheme. The cylinder 32 in the molding mechanism 3 pushes the stamping mold 31 to complete the stamping operation. At the same time as stamping, the feeding unit and the stamping mold 31 are mechanically linked synchronously, so that the stamping mold 31 performs the feeding operation when going up and performs the reset operation when stamping downward. The linkage structure enables the two to be linked synchronously, avoiding the need for additional numerical control equipment to control them. While ensuring accuracy, it also effectively reduces the economic cost, killing two birds with one stone and being simple and efficient.

[0033] Specifically, in this embodiment, the scheme mainly includes a base 1, a gantry 2 and a molding mechanism 3. During stamping, the stamping die 31 moves upward to drive the linkage plate 38 and the driven plate 39 to move in linkage, and then the sheet to be processed in the storage barrel 36 is pushed out into the slot 35 through the push plate 310. When the stamping die 31 moves downward for stamping, the push plate 310 is synchronously linked and reset, and at the same time, the sheet is stamped by the stamping die 31 to be bent. After the stamping is completed, the stamping die 31 moves upward to drive the push plate 310 to repeat the above steps, and the stamped sheet is squeezed out through the new sheet to be processed.

[0038] In this embodiment, the up and down movement of the stamping die 31 drives the linkage plate 38 and the driven plate 39 to move in conjunction, thereby enabling the push plate 310 to slide back and forth on the die pressing seat 33 .

[0039] In a further preferred embodiment of the present invention, Figure 1-4 As shown, a slider 312 is fixed to the bottom of the driven plate 39 , a guide rail 311 is fixed to the base 1 , and the slider 312 is slidably engaged in the guide rail 311 .
