What are the shortcomings of speaker mesh metal?
Not all products we produce are intact. In the process of manufacturing, it is inevitable that there will be some products that are not very good. Not all products are perfect, and some products have shortcomings. Let's take a look at the shortcomings of the correction method of the horn mesh punching mesh.
1. Correction of local pain during punching: When punching, due to the uneven anvil surface, the two end faces of the punching head are uneven, and the blank is uneven during heating, local pain in the hole will occur. The correction method can use the liquid immersion method: the operating side with a thin hole wall is immersed in water, so that the temperature decreases, and then the perforation aperture expands, so the wall thickness of the side is uniform due to high temperature, good plasticity and thinness, so the entire forging wall thickness is uniform , local pain is corrected. This method is suitable for materials with good plasticity.
2. When punching, the steel billet is sampled. That is, the metal under the punch is extruded from all sides, the height of the billet is reduced, the diameter is increased, the top is concave, and the bottom is convex. The degree of sampling before punching is related to the blank diameter D0, height H0, and hole diameter D1. The smaller D0/d1, the more serious the sampling degree.
The correction method is: when D0/D1≥2.5~3, the control effect is better. If the punch diameter is larger, such as D0/DL & LT; 2.5. Typically, the holes are drilled and then reamed to obtain the desired hole diameter.
The above explanations are about the shortcomings of the correction method for the related content of the horn net punching net. I hope it can help you after reading. If you want to know more about the horn net related content, please contact the online customer service. Serve.
