Description

Technical Field

[0001] This utility model belongs to the technical field of sheet forming machine, and in particular relates to a circular cover punching die for a sheet forming machine. Background Technology

[0002] In existing technologies, the circular cover punching die has blades that fit together along a single line, which is equivalent to the contact between circles. This results in a small contact area, unstable die-cutting, and virtually no mutual support between the blades. Consequently, the die lacks rigidity when it is high, leading to low material utilization during sheet forming. Utility Model Content

[0003] The purpose of this utility model embodiment is to provide a circular cover punching die for a sheet forming machine, which can increase the contact area and enhance the rigidity of the die.

[0004] The present invention is implemented as follows:

[0005] A circular cover punching die for a sheet forming machine includes: a die holder and a circular die. The circular die is disposed on the die holder. There are multiple circular dies distributed on the die holder. A straight contact edge is set between adjacent circular dies, so that the contact surfaces between adjacent circular dies form a planar contact.

[0006] The circular die is divided into a first circular die and a second circular die, with multiple first circular dies and multiple second circular dies.

[0007] The outer circumference of the circular die-cutting mold has at least two straight contact edges.

[0008] There are four first circular die-cutting dies and two second circular die-cutting dies.

[0009] This embodiment of the invention increases the contact area and rigidity by making the circular die-cutting dies have planar contact, and also increases material utilization. The large contact surface between the circular die-cutting dies ensures their rigidity and provides stable support to each other. Since the contact surface between the circular die-cutting dies is linear, the area of ​​the die holder is small for the same number of dies, thus improving material utilization during molding. Attached Figure Description

[0010] Figure 1 This is a structural diagram of the circular cover punching die for the sheet forming machine of this utility model. Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0012] The specific implementation of this utility model will be described in detail below with reference to specific embodiments:

[0013] like Figure 1 As shown, a circular cover punching die for a sheet forming machine includes: a die holder 1 and a circular die. The circular die is disposed on the die holder. There are multiple circular dies distributed on the die holder. A straight contact edge 4 is set between adjacent circular dies, so that the contact surfaces between adjacent circular dies form a planar contact.

[0014] The circular die-cutting mold is divided into a first circular die-cutting mold 2 and a second circular die-cutting mold 3. There are multiple first circular die-cutting molds and multiple second circular die-cutting molds.

[0015] In the figure, the outer circumference of the circular die has at least two straight contact edges. This allows the die to maintain planar contact even when it needs to rotate, increasing the contact area between the dies and ensuring rigidity.

[0016] In the diagram, there are four first circular dies and two second circular dies. This arrangement ensures the diversity of molded products, allowing two types of products to be molded simultaneously with the two dies, thus improving the efficiency of die-cutting processing.

[0017] This embodiment of the invention increases the contact area and rigidity by making the circular die-cutting dies have planar contact, and also increases material utilization. The large contact surface between the circular die-cutting dies ensures their rigidity and provides stable support to each other. Since the contact surface between the circular die-cutting dies is linear, the area of ​​the die holder is small for the same number of dies, thus improving material utilization during molding.

[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
