Description

Technical Field

[0001] The utility model belongs to the technical field of sheet material forming processing, in particular to a hardware punching die of a sheet material forming machine. Background Art

[0002] In the prior art, during sheet forming processing, the formed product needs to be punched in order to separate the product from the sheet body, thereby obtaining a sheet formed product. Punching is performed using a punching die. Ordinary hardware punching dies are strictly made according to the knife lines provided by the customer. The knife lines between the male and female molds do not form an effective match. After the mold is completed, burrs, rubber threads, and especially straight segments will appear during the mold trial process, resulting in unqualified molds and affecting the punching quality. Utility Model Content

[0003] The purpose of the embodiment of the utility model is to provide a metal punching die for a sheet forming machine, which can improve the punching quality of the die.

[0004] The utility model embodiment is achieved as follows:

[0005] A metal punching die for a sheet forming machine comprises a male die and a female die, wherein the female die is provided with an accommodating space for accommodating the lower portion of the male die, the knife line of the male die forms an arc-shaped blade, and the knife line of the female die forms a right-angled blade. The arc-shaped blade and the right-angled blade are tightly abutted to form a shearing blade of the die, and the shearing blade surrounds the contact point between the male die and the female die.

[0006] Wherein, the male mold is in the shape of a cuboid.

[0007] Wherein, the master mold is in the shape of a cuboid.

[0008] The male and female molds are provided with screw holes for fixing and air holes for providing air sources around them.

[0009] The embodiment of the present invention adjusts the die punching by adjusting the shapes of the knife lines of the male and female dies. The knife line of the male die is arc-shaped, and the knife line of the female die is right-angled. In this way, the knife line of the male die has an arc-shaped buffer and will not form a hard contact with the sheet, ensuring that the sheet will not be directly squeezed and damaged. The arc-shaped knife line also forms a sharp blade, forming a scissors principle with the knife line of the female die, effectively solving the problems of burrs, rubber threads, etc. that occur during the die trial process, thereby improving customer satisfaction and improving the punching quality of the molded products.

[0012] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0013] The following describes the specific implementation of the present invention in detail with reference to specific embodiments:

[0014] like Figure 1 and Figure 2 As shown, a metal punching die of a sheet forming machine includes: a male die 1 and a female die 2, the female die is provided with an accommodating space for accommodating the lower part of the male die, the knife line of the male die forms an arc-shaped blade 3, and the knife line of the female die forms a right-angled blade 4. The arc-shaped blade and the right-angled blade are tightly arranged to form a shearing edge of the die, and the shearing edge surrounds the contact point between the male die and the female die.

[0015] Wherein, the male mold is in the shape of a cuboid.

[0016] Wherein, the master mold is in the shape of a cuboid.

[0017] The male and female molds are provided with screw holes for fixing and air holes for providing air sources around them.

[0018] During the sheet forming process, the sheet is first cut by the shearing edges of the male and female molds, and the male and female molds form the cut sheet (usually by vacuuming or blowing), thus completing the forming process.

[0019] The embodiment of the present invention adjusts the die punching by adjusting the shapes of the knife lines of the male and female dies. The knife line of the male die is arc-shaped, and the knife line of the female die is right-angled. In this way, the knife line of the male die has an arc-shaped buffer and will not form a hard contact with the sheet, ensuring that the sheet will not be directly squeezed and damaged. The arc-shaped knife line also forms a sharp blade, forming a scissors principle with the knife line of the female die, effectively solving the problems of burrs, rubber threads, etc. that occur during the die trial process, thereby improving customer satisfaction and improving the punching quality of the molded products.

[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
