Description

Stamping die capable of preventing waste from floating upwards Technical Field The utility model relates to the technical field of stamping dies, in particular to a stamping die capable of preventing waste from floating upwards. Background Stamping refers to a press working method in which a sheet is pressed at room temperature by a die mounted on a press to be separated or plastically deformed, thereby obtaining a desired part. The stamping die is a tool for separating or deforming a blank, and is a special process equipment for processing a material (metal or nonmetal) into a part (or a semi-finished product) in cold stamping processing, and is also called a cold stamping die (commonly called a cold stamping die). The stamping die is an indispensable tool in stamping production, and the structure of the stamping die has great influence on the stamping production efficiency and the service life of the die. The working principle of the stamping die is that the stamping die is arranged on a stamping machine, stamping action is achieved through up-and-down movement of the die, a metal material to be processed is placed in a working cavity of the die and is attached to the upper portion and the lower portion of the die, and the stamping machine moves the die up and down through a mechanism and a transmission device. When the die moves downwards, the metal material is deformed under the action of stamping pressure, and after the die is pressed down in place, the stamping machine applies pressure to enable the die to perform stamping processing on the metal material. The metal material is impacted and deformed by the boss or the groove at the inner side of the die under the action of the stamping pressure, so that the metal material takes on the shape of a specified pattern and size. For example, in a stamping die for a metal part with the publication number CN221246709U in the prior art, the extension column extends to the outside of the mounting column to drive the first spring to deform, the extended extension column covers the surface of the side block, and then the extension column is driven to reset by the elastic action of the first spring, so that the surface of the side block can be in contact with the induction pad arranged on the inner wall of the extension column, the induction pad is extruded, the time consumed in the process of fixing the die can be effectively shortened, and the efficiency of part processing is improved to a certain extent. However, the prior art has the following problems that the punched waste floats upwards when the stamping die is produced and is stuck to the working surface of the die, so that the product is crushed, batch scrapping is frequently caused, the production efficiency is reduced, and the cost is increased. Based on the above, the utility model provides a stamping die capable of preventing waste from floating upwards. Disclosure of utility model In order to overcome the defects in the prior art, the utility model provides the stamping die for preventing the waste from floating upwards, wherein the stamping hole on the stamping female die is designed to be the angle taper hole, the straight arm hole and the blanking hole, and the waste cannot float upwards due to the limit of the junction of the blanking hole and the straight arm hole, so that the phenomenon that the waste floats upwards and is stuck to the working surfaces of the stamping male die and the stamping female die to cause the product to be crushed can be avoided, the rejection rate can be reduced, the production efficiency is improved, and the problems in the background art can be solved. In order to achieve the purpose, the stamping die capable of preventing waste from floating up comprises a stamping male die and a stamping female die which are distributed up and down, wherein a plurality of stamping heads which are distributed uniformly are fixedly arranged at the bottom of the stamping male die, stamping holes with the same number as the stamping heads are formed in the top of the stamping female die, each stamping hole comprises a cone hole, a straight arm hole and a blanking hole which are distributed from top to bottom in sequence, two exhaust pipes which are distributed symmetrically from top to bottom are arranged in the stamping female die, the number of the exhaust pipes is the same as that of the blanking holes, a filter screen is fixedly arranged in each exhaust pipe, and the two exhaust pipes are all communicated with a negative pressure component. In a preferred embodiment, the negative pressure assembly comprises an air suction pump, an air inlet pipe of the air suction pump is communicated with the two air suction pipes through a three-way pipe, and waste materials can be adsorbed to a certain extent by utilizing air suction of the air suction pump, so that the effect of preventing the waste materials from floating upwards is improved. In a preferred embodiment, the bottom of the air pu
