Abstract

The invention discloses a process for making C-shaped member in the metallic members of the plastic-steel door and window, wherein the C-shaped member manufacturing process of uninterrupted manufacture comprises the steps of, uncoiling the coiled steel on the decoiler, controlling by a first buffer storing device, feeding the belt steel into the progressive forming machine to form a C-shaped cross-section, controlling by a second buffer storing device, sending by the self-feeding machine into punching machine for gap punching, perforating, cutting-off and bending.

Description

technical field [0001] The invention relates to a method for manufacturing plastic-steel door and window hardware, in particular to a method for manufacturing a C-shaped piece used at the corner of the plastic-steel door and window hardware system. Background technique [0002] The so-called C-shaped piece is an important part used at the corner in the plastic-steel door and window hardware system, such as figure 1 , figure 2 and image 3 The structure of the C-shaped piece shown is made of 0.8 mm thick raw strip steel, and its cross-section is as follows image 3 For the C shape shown, the groove gap at the corner of the C-shaped piece is required to be greater than or equal to 0.9 mm. The C-shaped piece is bent at 90° to be equilateral and right-angled. A long hole 3 and two circular holes 1, 2 are arranged on the bottom plates of the two right-angled sides, and grooves 4 are formed at both ends of the bottom plate. The manufacturing method of the C-shaped part with t...
