[0018] The preferred embodiments of the present invention will be further described below.
[0019] In order to achieve the purpose of the present invention, in one of the embodiments of the present invention, a method for processing a winch for a rope closing machine is provided, which includes the following steps:
[0020] Step one: heating the alloy steel billet to the forging temperature to forge the outer ring parts with a plurality of concave arc surface structures evenly distributed on the inner circumferential surface;
[0021] Step 2: Use a mold to cast the tapping plate body, form a first through hole structure on the shaft center of the steel plate body, and form a plurality of concave arc surface structures in the steel plate on the circumferential surface of the steel plate body;
[0022] Step 3: Weld the outer ring member to the circumferential surface of the steel plate body in the incubator, so that the inner concave arc surface structure of the steel plate matches the ...
