Embodiment

[0023] Taking the most widely used hydraulic support column in coal mine machinery as an example, the repair process of the present invention includes the following steps:

[0024] ⑴Cleaning and sorting

[0025] First, the mine machinery and equipment to be repaired will be transported to the raw material yard for unified storage, and then the stored mine machinery and equipment to be repaired will be transported to the cleaning and sorting workshop according to the order of demand, and then the mechanical equipment will be washed with a high-pressure water gun to remove the oily sludge on the surface. Use the CZ-1-45 single pillar dismantling machine for disassembly, cleaning and sorting. The sorted parts are ultrasonically cleaned with a special cleaning solution under ultrasonic treatment conditions, and then washed with warm water at 60°C, and finally Use a 24 cubic meter air compressor to generate hot compressed air to dry the parts, and use the recycling device to recycl...

Abstract

The invention discloses a mine waste machine repair process, and belongs to the field of machine remanufacturing. The process comprises the steps of: cleaning and sorting, analysis and estimation, derusting and premachining, repair and remanufacturing, quality inspection and assembly. The mine waste machine repair process uses waste mine mechanical products as blanks, uses the remanufacturing quality control and the advanced surface engineering technology for repairing failed surfaces to recover geometric sizes, reduces the use of new materials in the remanufacturing process to the greatest extent, recovers and promotes the product quality and performances, prolongs the product service life, improves the product reliability, reduces the maintenance costs of remanufactured products, reduces the energy consumption and the pollution emission generated in chain production, realizes the equipment performance promotion and great-leap-forward development requirements under lower cost, and excavates additional values contained in waste parts to the greatest extent.

Description

technical field [0001] The invention belongs to the field of mechanical remanufacturing, and in particular relates to a process for repairing waste and old machinery in mines. Background technique [0002] As a resource-rich country, my country has a huge amount of mining, a huge amount of mining machinery and equipment, and a huge potential for remanufacturing of mining machinery and equipment. Remanufacturing engineering is guided by the theory of the whole life cycle of equipment, with the goal of improving the performance of waste equipment, with high quality, high efficiency, energy saving, material saving, and environmental protection as the criteria, and with advanced technology and industrialized production as means to repair, The general term for a series of technical measures or engineering activities to transform waste and old equipment. In short, remanufacturing engineering is the industrialization of high-tech restoration and transformation of waste equipment. ...
