How to improve the quality and service life of mold accessory punches? I think this is the answer that any mold accessory purchasing door wants to know.

First, let's take a look at the types of punches and the materials used:

Punch: Also known as punch needle, punch die, punch rod, punch nail, punch punch, punch die.

Types of punches: standard punch, B-type punch, A-type punch, tooth extraction punch A-type, tooth extraction punch MP type, tooth extraction punch SP type, guiding punch BPP type, guiding punch APP type, conical punch, conical double-section punch, A-type three-stage punch, standard parent-child punch, special-shaped punch, and special-shaped punch is also called forming punch.

Forming punches: They are further classified into SAD type four-corner punches, SAR type four-corner R punches, SAG type double-sided cutting punches, SAE type elliptical punches, SAT type triangular punches, and SAS type hexagonal punches. There are also fan-shaped punches, crescent-shaped punches, etc. Titanium-coated punch

The materials for producing punches are respectively: SKD-11, SKH-51, SKH-9, ASP-23, ASP-60, and M42.

In recent years, the competition in the global mold punch manufacturing industry has become increasingly fierce. The ability of enterprises to provide customers with personalized and high-quality products in the shortest possible time with low consumption has become a symbol of an enterprise's competitiveness. Molds are known as the father of industry. The quality of mold accessories and punches will directly affect the quality, output, cost of products, the cycle of new product commissioning and the renewal of old products, the speed of enterprise product structure adjustment and market competitiveness. Therefore, the economic situation has put forward increasingly higher requirements for the quality of mold accessories and punches. So how can the quality of the die punch be improved more reasonably? That is to say, how can the die punch produce qualified parts for a longer time and more die passes under high-precision and low-cost conditions? This has increasingly become the focus of people's attention. The quality of die punches is not a simple topic. It includes the following aspects:

(1) Die punch quality: the stability and compliance of product dimensions, the surface finish of the punch, the utilization rate of punch material, etc. When designing the mold structure, it is necessary to make it as compact as possible, easy to operate, and ensure that the mold punch parts have sufficient strength and rigidity. When the structure of the die punch allows, the corners of each surface of the die punch parts should be designed as rounded transitions as much as possible to avoid stress concentration. For the die, cavity and part of the punch and core, a combined or pin insertion structure can be adopted to eliminate stress concentration. For slender punches or cores, appropriate protective measures need to be taken in the structure. For cold stamping dies, devices should be configured to prevent the workpiece or waste from being blocked (such as: spring pins, compressed air, etc.). At the same time, it is also necessary to consider how to reduce the impact on the quality of the die punch caused by the wear of sliding mating parts and frequently impacted parts during long-term use.

⑵ Service life of the die punch: Under the premise of ensuring the quality of the punch, the number of working cycles that the die punch can complete or the quantity of parts produced;

⑶ The use and maintenance of the die punch: Whether it is convenient to use, easy to demold, and the auxiliary production time is as short as possible;
