2024 aluminum tube in the extrusion production, more or less there will be some problems, the 2024 aluminum tube manufacturer is how to solve the problem of 2024 aluminum tube extrusion production?I'm going to introduce it to you.

I. The 2024 aluminum tube has seam Angle or poor welding

There are two reasons for the gap of 2024 aluminum tube. First, the shunt hole and welding chamber are narrow, and the metal supply is insufficient. The metal does not form enough hydrostatic pressure in the welding chamber, and the mold hole flows out because the product is not well welded, leading to the welding gap of the product.Grinding or milling can be used to enlarge the area of the shunt hole and welding chamber to increase the metal flow, so that enough hydrostatic pressure can be formed in the welding chamber to solve the problem.Secondly, due to excessive lubrication and poor lubrication, resulting in poor weldability in the hollow section.No lubrication extrusion process can be used.

Second, 2024 aluminum tube wall appears concave or convex arch surface

1. Causes: The working strip of the die core is lower than the working strip of the lower die hole. Too short the effective data length time of the working strip of the die core will cause the concave arch surface under the wall of 2024 aluminum tube.

Solution: it is necessary to make the working belt of the die core equal to the aperture area of the lower die under the stress state.A spacer ring can be placed between the die core and the lower die while the same thickness is subtracted from the lower die outlet.

2. Important reasons: The mold design has been used for too long, and the working belt of the mold core seriously affects the wear and tear, causing grooves and increased friction resistance, resulting in the protruding of 2024 aluminum tube wall.

If the mandrel has a certain degree of wear when working, and the wall thickness reaches 2024 aluminum deviation;2024 Aluminum wall thickness tolerances allow if it can be filed or ground mandrel working surface with reduced friction: corrected, the mold can be preheated to about 300℃, the shape of the weld core, and then submitted to the required dimensions and polished after use for repair.
