How to adjust the blade of the shearing machine

There are many kinds of plate shears and different adjustment methods, so no matter what model, it is not the blade of Nanjing shear blades that can be adjusted by anyone. You can ask a professional master to debug, otherwise you may hurt your body if you don't say it accurately. Before adjusting the clearance, we need to check whether the shear blade are repaired or adjusted after changing the blades. We should carefully adjust them step by step according to the type and thickness of materials.

First, adjust the screw in the stop on the workbench. After rotating the screw, the workbench can move back and forth, so as to adjust the gap between the upper and lower blades. The indicating machine installed on the column can read the movement of the worktable. When the blade gap is too large, the cutting part of the plate will be deformed and burred; If the blade clearance is too small, the plate will be crushed, and the machine tool will be damaged in serious cases. Therefore, it is very important to adjust the clearance of the blade of the plate shear.

At present, the common hard bits in the Chinese market are mainly from industrial developed countries such as Europe, the United States and Japan, such as Sandvik, Kenner, cobalt collar, Titex, mapa, Mitsubishi, Sumitomo and Ouji in Japan. According to the investigation of Luo Baihui, Secretary General of the International Mold Association, most of these enterprises have a large inventory of standard drill bits in Singapore or mainland China, and some non-standard drill bits are also produced in China. The quality of drill bit products in South Korea and Taiwan is not strong, so they are rare in the market.

The gap between most domestic cutting tool enterprises and international first-line cutting tool brands in the aspect of hardened bit mainly lies in the design concept, manufacturing details, material selection and coating treatment. The specific products with large gap in bit performance at home and abroad include: drill for processing steel parts, deep hole fried dough twist drill instead of gun drill, drill for processing high-temperature alloy, high hardness steel and other materials. In these fields, only a few domestic enterprises have mastered the design and manufacturing technology. The present situation of hardened end milling cutters. Hardened end milling cutters can be divided into general type and type. Generally speaking, the technical difficulty of general hardened end milling cutter is relatively small, and the gap between product quality and foreign countries is not very large. In fact, the vast majority of cemented carbide tool enterprises in China, including private tool enterprises, state-owned tool factories and tool enterprises in Taiwan on the mainland, mainly focus on the production of hardened end mills. Domestic hardened end mills occupy most of China's middle and low-end markets at low prices, and the competition is also very fierce.
