Description

Stamping die for solving spring piece punching waste jumping

Technical Field

The utility model relates to a stamping process's field, concretely relates to solve spring leaf punching waste material and jump up stamping die.

Background

The scrap jumping up refers to a phenomenon that the material retained in the female die is taken out along with the rising of the male die and then falls on the surface of the female die due to elasticity of the scrap after being sheared and separated in the punching process. When the stamping processing production is carried out, if the phenomenon of scrap jumping occurs, on one hand, safety accidents can occur due to carelessness of operators; on the other hand, the product is scrapped, and the mold is damaged, and other serious quality problems are caused. Therefore, corresponding precautions must be taken to prevent the scrap from jumping up.

In order to prevent the waste jumping during punching, the traditional method is to add an ejection pin on a punch, but the method has the following defects: after the ejector pin is added on the punch, the die is inconvenient to repair and grind a knife edge; when the punch is small, the ejector pin on the punch is also easy to break due to the small size.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of prior art existence, and provide a solve spring leaf punching press mould that the waste material jumped upward, have simple structure, convenient to use, safe and reliable's advantage.

The purpose of the utility model is accomplished through following technical scheme: the stamping die for solving the problem of spring piece punching waste jumping comprises a punch, a product, a female die, a lower cushion plate, waste and a gas pipe joint, wherein a through upper blanking channel is formed in the female die; the lower base plate is contacted and attached with the lower surface of the female die, and a through blanking channel is arranged on the lower base plate at a position corresponding to the upper blanking channel, so that waste materials are discharged out of the lower base plate along the upper blanking channel and the blanking channel; an air inlet channel is formed in the lower base plate, one end of the air inlet channel is communicated with an air pipe joint arranged on one side of the lower base plate and used for introducing air flow, an inclined outlet is formed in the other end of the air inlet pipeline and communicated with the side wall of the lower blanking channel, and the air flow enters the lower blanking channel.

As a further technical scheme, the air pipe joint and the lower backing plate are sealed through a gasket.

As a further technical scheme, the size and the direction of the airflow entering the falling material channel are adjusted by adjusting the size and the inclination angle of the inclined outlet.

As a further technical scheme, the inner diameter of the upper blanking channel is gradually increased from top to bottom.

The utility model has the advantages that: the waste materials generated after stamping are directly discharged out of the lower backing plate along the direction of air flow, the phenomenon that the waste materials jump upwards is avoided, and the safety of the production process is improved.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Description of reference numerals: the device comprises a punch 1, a product 2, a female die 3, an upper blanking channel 3-1, a lower backing plate 4, a lower blanking channel 4-1, an air inlet channel 4-2, an inclined outlet 4-3, waste 5, a gasket 6 and an air pipe joint 7.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

example (b): as shown in the attached drawing 1, the stamping die for solving the problem of spring leaf punching waste jumping comprises a punch 1, a product 2, a female die 3, a lower backing plate 4, a waste 5 and a gas pipe joint 7, wherein a through upper blanking channel 3-1 is formed on the female die 3, a female die knife edge is arranged at the position, corresponding to the upper blanking channel 3-1, of the upper surface of the female die 3, the product 2 is arranged at a female die knife edge position on the upper surface of the female die 3, the punch 1 driven to lift by an external mechanism is arranged right above the female die knife edge and used for stamping the product 2, and the waste 5 is formed at the female die knife edge position; the lower backing plate 4 is contacted and attached with the lower surface of the female die 3, a through falling material channel 4-1 is arranged at the position, corresponding to the upper falling material channel 3-1, on the lower backing plate 4, so that the waste 5 is discharged out of the lower backing plate 4 along the upper falling material channel 3-1 and the falling material channel 4-1 (preferably, the inner diameter of the upper falling material channel 3-1 is gradually increased from top to bottom, and the inner diameter of the falling material channel 4-1 is slightly larger than that of the bottom of the upper falling material channel 3-1); an air inlet channel 4-2 is arranged in the lower backing plate 4, one end of the air inlet channel 4-2 is communicated with an air pipe joint 7 arranged on one side of the lower backing plate 4 and used for introducing air flow, the other end of the air inlet pipeline 4-2 is provided with an inclined outlet 4-3, and the inclined outlet 4-3 is communicated with the side wall of the lower material falling channel 4-1 so that the air flow enters the lower material falling channel 4-1.

Preferably, the air pipe joint 7 is sealed with the lower gasket 4 through a gasket 6. The inclined outlet 4-3 is arranged obliquely downwards, and the axis of the inclined outlet 4-3 is 45 degrees with the axis of the falling material channel 4-1.

The utility model discloses a theory of operation: during punching, the air pipe joint 7 is connected with the air inlet channel 4-2 and is ventilated; the product 2 is placed at a die cutter opening on the upper surface of the die 3, and then an external mechanism is driven to drive the punch 1 to press downwards, so that the product 2 is sheared and separated to form waste 5; when the punch 1 is lifted up, a short vacuum state can be formed between the lower end face of the punch 1 and the upper end face of the waste 5, and air flow introduced into the lower blanking channel 4-1 and the upper blanking channel 3-1 from the air inlet channel 4-2 can enter the vacuum region along gaps between the two sides of the waste 5 and the inner wall of the upper blanking channel 3-1, so that the waste 5 is finally discharged out of the lower backing plate 4 along the upper blanking channel 3-1 and the lower blanking channel 4-1 under the dual effects of gravity and air flow to complete blanking. The size and the direction of the air flow entering the lower blanking channel 4-1 are adjusted by adjusting the size and the inclination angle of the inclined outlet 4-3, so that the blanking device is suitable for the waste 5 generated by stamping different products 2.

It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
