Professional steel toe cap mold supplier
High-precision stamping quality supplier
product description
The steel head mold of safety shoes is divided into five parts for stamping and forming. The structure of this mold is simple and easy to operate and easy to maintain. If the factory has a strong mold repairer, you can make a 4-part mold to complete, one of which is a more complex composite mold.First, let’s talk about the 5-part mold process. It consists of a set of pressing marking and blanking, stretching the bowl, slicing, side trimming, and finally forming a total of 5 molds.
Next, let's talk about the processes completed by the four sets of molds: 1. Press and mark a set of blanking and stretch a composite mold, toss and cut, side trimming, and flanging are completed. The first pair of this mold is more complicated and needs to be completed by a strong maintenance worker. Generally not recommended
The grade is divided into An1, An2, An3, An4, An5, the static pressure of the toe cap is 15KN, 10KN, 4.4KN, 3.0KN, 1.5KN, and the internal clearance of the toe cap is ≥15mm. The safety shoes of grades An1, An2, and An3 fall freely from the height of 900mm, 450mm, and 225mm respectively with a 23Kg impact hammer, and the internal clearance of the toe cap is ≥15mm. Safety shoes of grades An4 and An5 fall freely with a height of 450mm and 225mm respectively with a 5Kg impact hammer, and the internal clearance of the toe cap is ≥15mm.
An1 is suitable for operations in metallurgy, mining, forestry, ports, ships, loading and unloading, quarrying, heavy industry, etc.; An2 is suitable for operation in machinery, construction, petrochemical and other workplaces; An3 is suitable for electronics, food, medicine and other industries; An4 ～An5 is suitable for the textile industry and clamp work. It is a labor protection shoe (labor protection shoes) used to avoid injury to the toes. It is an essential product for labor protection.
common problem
How does your company achieve material savings in order to reduce costs?
The blanking gap is the main factor that affects the size of the burr, but the degree of influence varies greatly when the material is different. The picture on the right shows the changing law of the burr height of the low-carbon steel sheet blanking part.
The determination of a good gap?
The burr height h has a relatively stable stage with the change of the relative blanking gap Z/t. When the value of Z/t changes between 8% and 14%, the value of h changes very little. When Z/t is too large or too small, the value of h may increase.
The determination of a good gap?
The main basis of the theoretical determination method is to ensure the overlap of the cracks to obtain a good blanking section. The picture shows the instantaneous state of cracks in the punching process.
