preparation example Construction

[0027] Step 1. Preparation of rubber strips: Pass the track compound rubber and vulcanizing agent on the open mill at a mass ratio of 100: (0.5-1.5), so that the track compound rubber and vulcanizing agent are mixed evenly and air bubbles are removed to obtain rubber Mixed material; then the rubber mixed material is preformed by a rubber extruder to obtain a cylindrical solid mixed rubber material, and the mixed rubber material is cut into 2000-3000mm rubber strips;

[0028] Step 2. Surface treatment of the metal wheel body: sand blast the outer surface of the metal wheel body, and then use a silane coupling agent to clean the sandblasted metal wheel body to completely remove the dust, oil and rust on the surface of the metal wheel body. Stand for 10-30min for use;

[0029] Step 3: The construction process of the adhesive layer: Apply the adhesive layer evenly on the outer surface of the metal wheel body obtained in step 2 by brushing or spraying, which specifically includes f...

Abstract

The invention discloses a road wheel and a press-casting process thereof. The process comprises preparation of a rubber strip, surface treatment of a metal wheel body, a construction process of an adhesive layer and forming of the road wheel. Meanwhile, the invention further discloses the road wheel prepared by the press-casting process. The process comprises the specific steps: performing abrasive blasting and silane coupling agent treatment on the outer surface of the metal wheel body; then coating the adhesive layer for many times; and finally performing vulcanization forming at one time with a 300-330 tonnage hydraulic press, so that the problems that the bonding power of the metal wheel body and the rubber layer is poor, and the rubber layer on the surface of an outer ring of the metal wheel body is easily layered, the inner part of the rubber layer is not dense and the rubber layer is not uniformly vulcanized are solved. Moreover, by adopting the press-casting process, complex steps of a winding method are avoided, the steps are simplified, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of road wheel processing, and in particular relates to a road wheel and its casting process. Background technique [0002] At present, there are mainly two types of construction vehicles: wheeled and tracked. For different terrains, different models need to be used for operations. Wheeled vehicles are suitable for ordinary ground with flat terrain and hard surface. Tracked vehicles are suitable for soft ground and harsh terrain. The track wheel is a special walking device with the characteristics of both tires and tracks. It is mainly used to solve the problem of poor passability of vehicles in complex and harsh terrains such as tidal flats, swamps, deserts, fields, ice and snow, and gravel. Compared with the integral track , track wheels have better terrain adaptability and smaller turning radius; compared with ordinary tires, track wheels have the advantages of larger ground contact area and smaller gro...
