Problems solved by technology

But using this production method, the material of the whole guide wheel body is still the same, and there is still the problem of wasting materials. In addition, the hub of the guide wheel body needs to be welded and then processed, and the process is relatively complicated, and there is still room for further improvement. Enter

Embodiment Construction

[0045] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0046] A production process of a guide wheel body includes the following steps:

[0047] S1: Make the rim, cut a quantitative carbon alloy structural steel billet, place it in a heating furnace and heat it to 1150°C-1250°C, and then place it in the forming mold of the roller compactor for rolling to obtain the rim. The rolled rim has a higher density and a more uniform wall thickness. The molding die of the roller compactor has a cavity corresponding to the shape of the rim. The specific carbon alloy structural steel model can be selected according to needs. The alloy structural steel selected in this embodiment is 40Mn2. For the wheel body of the guide wheel with a larger diameter, because it is mainly used for large-scale equipment, it needs to be loaded The pressure is greater, and the alloy structural steel here is preferably 35 chromium-molybdenum alloy s...

Abstract

The invention relates to a production technology of caterpillar band parts, in particular to a production technology of a guide wheel body for a caterpillar band. The production technology of the guide wheel body comprises the steps of rim manufacturing, hub manufacturing, spoke manufacturing, rib manufacturing, wheel body welding, hot processing, finish machining and the like. By means of the production technology of the guide wheel body, the traditional integrally-cast guide wheel body is divided into a rim, a hub, a spoke and ribs, and the parts are manufactured separately and connected together in a welding mode. Therefore, the parts of the guide wheel body can be made of corresponding materials according to actual stress conditions and have no need to be made of high-cost alloy steel, so that cost of the whole guide wheel body is low. Forging and punching shear replace traditional casting, so that non-uniformity of the wall thicknesses is avoided, and the formed material is larger in density and better in abrasion resistance.

Description

Technical field [0001] The invention relates to a production process of track parts, in particular to a production process of a guide wheel wheel body for a track. Background technique [0002] Crawler excavators have been widely used in infrastructure, water conservancy projects, road paving and other fields. The walking mechanism of crawler excavators includes the chassis and track shoes, chains, guide wheels and other components on the chassis, which guide The role of the wheel is to guide the chain walking. At present, the guide wheel body on the market is generally made of alloy steel casting. The material of the entire wheel body is the same. In actual use, the force of the wheel body is mainly concentrated on the shoulders on both sides, resulting in a waste of material , In addition, the guide wheels produced by casting have uneven wall thickness, and the thin wall is prone to cracking. [0003] Chinese invention patent ZL200810070734.1 discloses a method for producing gu...
