Problems solved by technology

The winch used for rope closure is an important component for transmitting variable loads and large torques. In the prior art, the winch is mainly a steel casting structure. During casting, air holes are easily generated on the circumferential surface of the winch, resulting in shrinkage cavities on the circumferential surface of the winch.

Embodiment Construction

[0018] 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 processing method of a winch for a rope closing machine is provided, comprising the following steps:

[0020] Step 1, heating the alloy steel billet to the forging temperature, and forging an outer ring member with a plurality of concave arc surface structures evenly distributed on the inner peripheral surface;

[0021] Step 2, using a mold to cast the steel plate body, forming a first through-hole structure on the axis of the steel plate body, and forming a plurality of steel plate concave arc surface structures on the circumferential surface of the steel plate body;

[0022] Step 3, welding 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 inner con...

Abstract

The invention discloses a processing method of a winch for a crank closer. The processing method comprises steps as follows: step one, alloy steel blank is heated to a forging temperature, and multiple outer ring parts with indent cambered surface structures uniformly distributed on the inner circumferential surface are forged; step two, a steel disc body is cast by a die, a first through hole structure is formed in an axis of the steel disc body, and multiple steel disc indent cambered surface structures are formed on the circumferential surface of the steel disc body; step three, the outer ring parts are welded on the circumferential surface of the steel disc body in a heat insulation box, and the steel disc indent cambered surface structures are matched with the indent cambered surface structures of the outer ring parts, and a second through hole structure is formed; step four, the welded winch is subjected to quenching. Compared with the prior art, the processing method has the advantages that the outer ring parts of the winch are forged and then welded on the steel disc body, so that hardness of the winch is guaranteed, shrinkage cavities in the circumferential surface of the winch are avoided, and qualification rate of products is increased.

Description

technical field [0001] The invention relates to a processing method of a winch for a rope closing machine. Background technique [0002] The rope closing machine is a device that helically arranges the rope strands around the center line of the rope core to produce steel wire ropes. The winch used for rope closure is an important component for transmitting variable loads and large torques. In the prior art, the winch is mainly a steel casting structure. During casting, air holes are easily generated on the circumferential surface of the winch, resulting in shrinkage cavities on the circumferential surface of the winch. Phenomenon, affecting the quality of the winch. [0003] Therefore, need badly a kind of processing method of rope closing machine winch. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a processing method of a winch for a rope closing machine. [0005] In order to achieve the above object,...
