Description

A high-speed stamping die for thin profiles

technical field

The utility model relates to a high-speed stamping die for thin profiles, which belongs to the technical field of stamping dies according to the International Patent Classification (IPC).

Background technique

When thin strips are punched at high speed, the waste with regular geometric dimensions will be drawn back by the punch, and negative pressure will be generated instantaneously, or the punching oil will make the waste stick to the surface of the punch, take it out of the die, and randomly drop into the mold, causing the workpiece to press. Injuries and poor dimensions seriously affect product quality and production efficiency.

Therefore, the inventor considers improving the existing high-speed stamping dies for thin profiles, and this case arises from this.

Utility model content

Aiming at the deficiencies of the prior art, the utility model provides a high-speed stamping die for thin profiles, which adopts an anti-chip mechanism to handle waste materials during the high-speed stamping process of profiles.

In order to achieve the above object, the utility model is achieved through the following technical solutions:

A high-speed stamping die for thin profiles, the stamping die includes an upper cover plate, an upper mold base, an upper backing plate, a splint, a backing plate, a stripper plate, a lower template, a lower backing plate and a lower mold base from top to bottom, An anti-chip skipping mechanism is arranged between the upper mold base and the lower backing plate, and the anti-chip skipping mechanism cooperates with the thin profile to be stamped at high speed to realize the cleaning of waste materials after stamping.

Further, the anti-chip skipping mechanism includes an air pipe assembly, a punch and a die. The air pipe assembly is sequentially passed through the upper backing plate to the punch and cooperates with the cavity in the punch to realize air blowing, while the die is located directly below the punch and cooperates with the protrusion to realize stamping.

Further, the air pipe assembly includes an air pipe and an air pipe connector, and the air pipe extends into the upper backing plate from one side of the upper backing plate and is bent to realize the connection with the punch, while the air pipe joint is set and ventilated. The air pipe is exposed at the outer end of the upper backing plate to realize the introduction of compressed gas or air.

Further, the concave die is a rectangular body, and a thin profile to be stamped at high speed is placed on the upper end thereof. A punching hole is opened in the center of the concave die, and the punching hole cooperates with the punch to realize punching.

Further, the punch is a stepped tubular body and vertically penetrates the splint, the backing plate, and the stripper plate, the upper end of the punch is connected with the air pipe assembly and communicated, and the other end is located above the die.

Further, the concave mold is located in the lower template and arranged under the convex mold, and a stepped punching hole is opened therein.

Further, the minimum diameter of the punching hole is located on the upper end surface of the die and has a radius of 0.25mm.

Further, a thin groove is provided on the edge of the punching hole.

Further, the inner diameter of the groove is 0.03mm.

Compared with the prior art, the utility model has the following advantages:

The utility model adopts an anti-jumping mechanism to achieve the treatment of waste materials in the high-speed stamping process of profiles; compressed air passes through the air pipe, air pipe joint, and the pipe in the punch to force the cut waste materials to be blown away from the surface of the punch in an instant, preventing the waste materials from being carried out of the concave. Die; for extremely small workpiece holes, considering the strength and processing difficulty of the punch, you can only make some modifications on the die (as shown in the schematic diagram, a 0.03mm groove is processed in the die), and use the small groove to increase the resistance of the scrap to bring out , to prevent waste from being brought out of the die to achieve the purpose of preventing chip skipping.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

Embodiment: Please refer to Fig. 1, a high-speed stamping die for thin profiles, which includes an upper cover plate 1, an upper mold base 2, an upper backing plate 3, a clamping plate 4, a backing plate 5, Stripping plate 6, lower template 7, lower backing plate 8 and lower mold base 9, an anti-chip skipping mechanism 10 is arranged between the upper mold base 2 and the lower backing plate 8, and the anti-chip skipping mechanism 10 is compatible with the high-speed stamping The thin profile A cooperates to realize the cleaning of waste after stamping.

Please refer to FIG. 1 to FIG. 5 , the anti-chip skipping mechanism 10 includes an air pipe assembly, a punch 101 and a die 102 . The air pipe assembly is sequentially passed into the punch 101 from the upper backing plate and cooperates with the hollow cavity of the punch 101 to realize air blowing, while the die 102 is located directly below the punch 101 and cooperates with the protrusion to realize stamping;

The aforesaid air pipe assembly includes an air pipe 103 and an air pipe joint 104, and the air air pipe 103 extends into the upper backing plate 3 from one side of the upper backing plate 3 and is bent to realize connection with the punch 101, and the air pipe joint 104 Then the air pipe 103 is arranged and exposed on the outer end of the upper backing plate 3, so as to realize the introduction of compressed gas or air;

The aforementioned die 102 is a rectangular body, and its upper end face is placed with a thin profile A to be stamped at high speed. The center of the die 102 is provided with a punching hole 1021, and the punching hole 1041 cooperates with the punch 103 to realize punching. The aforementioned punch 103 is stepped. The pipe body is vertically pierced on the splint 4, the backing plate 5, and the stripping plate 6. The upper end of the punch 103 is connected with the ventilation pipe assembly and communicated, and the other end is located above the die 102, and the die 104 is located at the bottom. The template 7 is arranged below the punch 101, and a stepped punching hole 1021 is provided in it. The minimum diameter of the punching hole 1021 is located on the upper end surface of the die and the radius is 0.25mm. The edge of the punching hole 1021 is provided with a small Groove 1022, the inner diameter of the groove 1022 is 0.03mm.

The working principle of the utility model is as follows:

Compressed air passes through the air pipe 103, the air pipe joint 104, and the pipes in the punch 101 to force the cut waste to be instantly blown away from the surface of the punch to prevent the waste from being carried out of the die;

For extremely small workpiece holes, considering the strength and processing difficulty of the punch 101, only some modifications can be made on the die 102 (a groove of 0.03mm is processed in the die 102), and the small grooves are used to increase the resistance of the scrap material to prevent the The waste material is taken out of the die 102 to achieve the purpose of preventing chip skipping.

The above records are only examples of using the technical content of this creation. Any modifications and changes made by those who are familiar with this technology using this creation belong to the scope of patents claimed by this creation, and are not limited to those disclosed in the examples.
