Combined degumming method for rubberized track shoe

Abstract

The invention provides a combined degumming method for a rubberized track shoe. According to the method, low-temperature treatment and solution soaking are combined to remove glue; when the rubber onthe old rubber-coated track shoe subjected to low-temperature freezing reaches the characteristics of brittle materials (similar to common glass and cement products), the rubber can be recycled; the rubber body is knocked by a manipulator or a manual hammer; the irregular fragments are separated from the metal matrix; wherein the removal rate can reach 98%-99% according to the bonding area, then the material is transferred into a solution in the second step to soak and remove the rubber, a rubber remover permeate and dissolve along the bonding interface of the rubber and the metal, and meanwhile, the residual rubber is subjected to volume expansion under the soaking of the rubber remover, so that the bonding agent is invalid, and the residual rubber is automatically separated from the metal. After low-temperature treatment, knocking and degumming, little rubber remains on the metal matrix, and the solution soaking and degumming time can be greatly shortened. The rubber remover adopts an environment-friendly formula, does not contain toxic components such as dichloromethane and methane chloride, and is pollution-free.

Description

technical field [0001] The invention relates to the technical field of mechanical component processing, in particular to a combined deglue method for glued track shoes. Background technique [0002] The mobile system of crawler equipment is equipped with various parts made of metal and rubber such as rubberized track shoes, rubberized track pins, rubberized road wheels, and rubberized drag wheels. The service life of rubber materials is relatively short in the use of equipment. Taking rubber-mounted track shoes as an example, the rubber on the ground is basically ground flat after about 1,000 kilometers, and the rubber body cannot continue to be used. However, the life of the metal base of the track shoes is about 3,000 kilometers, far exceeding The life of the rubber, after the metal substrate is degummed, it can be recycled and reused, which can greatly save the cost of raw materials and reduce energy consumption. [0003] There are three kinds of degumming methods in the...

Problems solved by technology

The degumming process needs to precisely control the temperature of the heat transfer medium hot air to avoid annealing of the metal substrate, and a large amount of smoke and pungent smell are generated during the thermal processing, which does not meet the environmental protection requirements; the medium frequency induction heating method uses copper tubes as materials to process into The induction coil is connected with the intermediate frequency heating furnace. The principle is: the metal substrate is an excellent conductor of heat, and the metal substrate is rapidly heated by electromagnetic induction to make the adhesive contacting the metal invalid, and to realize the separation of the rubber from the metal substrate. Due to the shape of the metal substrate Irregularity, the distance between the metal surface and the heating coil is different, resulting in uneven heating of the metal, the heating temperature should not be precisely controlled, it is difficult to ensure the consistency of the physical and mechanical properties of the same metal substrate after degumming, a large amount of polluting gas is generated in the heating process, and even old rubber Combustion occurs, which does not meet the requirements of environmental protection; the main principle of the solvent soaking method is that the solvent soaks the rubber to swell, and after the swelling is saturated, the rubber and the metal matrix are automatically separated. The efficiency of this method is affected by the size of the composite parts. The volume of waste rubber The larger the size, the longer it takes to remove the rubber, and it is not suitable for the removal of old rubber in medium and large composite parts
