Scraper bolts can be divided into scraper E-bolts and U-bolts, and single bolts, and 134Se bolts is one of the many e-bolts scraper. Today I will take 134Se bolt as an example and talk about the processing technology of E bolt.
The processing method of type 134Se bolts is almost the same as that of the scraper. The general process is blanking â?? forging â?? machining â?? heat treatment â?? shot blasting â?? surface treatment â?? finished product inspection â?? packaging and delivery.
134Se type bolts are actually the choice of material when discharging. 40Cr material is used for 134Se type bolts of Henan Shuangzhi Machinery. Its mechanical properties and other aspects are relatively good, which is suitable for the production environment of coal mine. The raw material is melted at high temperature and injected into the 134Se bolt mould. Through continuous forging and pressing of the raw material, the blank of 134Se bolt is formed. The forging and pressing times shall not be less than 5 times. For the 134Se type bolt blanks, the excess flanges of The E type bolts were removed and threaded tapping was carried out. The oxide scale formed on the surface due to high temperature was further treated by shot blasting. Next is the treatment of the surface appearance, burr the 134Se type bolts and other treatment, as well as the appearance of painting, so that the E type bolts on the completion of the molding, and then the finished product inspection, to ensure that the qualified products can leave the factory, to carry out baling packaging shipment.
Henan Shuanzhi produces all kinds of bolts. Welcome to contact us if you need.
