Overlay welding and shape rolling device and re-manufacturing method

Abstract

The invention relates to an overlay welding and shape rolling device and a re-manufacturing method, wherein the overlay welding and shape rolling device comprises an overlay welding device, a spray nozzle and a guide rail, wherein a guide wheel is mounted on a walking support, the guide wheel runs on the guide rail, a shaping roller is mounted on the walking support, a baffle plate is connected on the walking support, and the baffle plate is positioned between the spray nozzle and the shaping roller. The re-manufacturing method for carrying out overlay welding and shape rolling by adopting the overlay welding and shape rolling device comprises the following steps: the step of producing the shaping roller; the step of producing the walking support; the step of arranging the guide rail; thestep of overlay welding; and the step of rolling. The re-manufacturing of a part can be completed through the steps. The invention provides the device and the method for carrying out filling and shape rolling for recovering the original surface shape and the size against irregular potholes, cracks and groove injuries with a certain depth, as well as deep abrasion on the surface of the part, thereby realizing the repair of the irregular injuries on the surface of the part, improving the shape and size precision of one-time repair, improving the tissue and mechanical properties of a repair layer, enhancing the bonding strength between the repair layer and a part matrix and reducing the repair workload.

Description

technical field [0001] The invention belongs to a remanufacturing method in the field of surface engineering, in particular to a surfacing welding rolling device and a remanufacturing method. Background technique [0002] Corrosion, excessive wear and cracking on the surface of parts is one of the main reasons for part failure. Traditional remanufacturing technologies such as surfacing, spraying, and cladding require subsequent machining or manual grinding after filling, which has low efficiency and low accuracy of manual grinding, and is not suitable for on-site repair of large-area damage to parts, especially those with certain shapes. Precision required fixes. In engineering practice, a large number of parts fail due to difficulty in disassembly or inconvenient machining after filling, resulting in huge economic losses. Contents of the invention [0003] The invention provides a method of filling and rolling to restore the original surface shape and size for the irreg...
