Problems solved by technology

The reel of the wire drawing machine has the characteristics of large wear-resistant layer area and thin wall (ratio of thickness to diameter: δ / D=0.02). It is easy to deform during spray welding and heating, and the quality of spray welding is not easy to control. The qualified rate of finished products is extremely low.

Embodiment Construction

[0017] Embodiments of the present invention are as follows:

[0018] Surfacing treatment is carried out on the surface of the wire drawing machine drum with a diameter of φ1270mm. The wire drawing machine drum is mainly composed of the drum body 1, the surfacing layer 2, the anti-deformation support ring 3, the anti-deformation support plate 4 and the processing positioning sleeve 5. The material of the reel body 1 is rolled from low carbon steel plate Q235.

[0019] The implementation steps of a surface welding treatment method for a reel of a wire drawing machine in the present invention are as follows:

[0020] (1) After the reel body is stress-relieved and heat-treated, the outer circle of the car is left with a surfacing layer thickness of 4mm, and the center positioning hole is turned out at the same time;

[0021] (2) The surface of the reel body is pretreated by sandblasting, degreasing and dewatering;

[0022] (3) The reel is preheated to 350-400°C in the electric f...

Abstract

The invention discloses a surfacing treatment method of a winding drum of a wire drawing machine. The surfacing treatment method comprises the following steps of: carrying out cylindrical turning a winding drum body subjected to destressed heat treatment, carrying out sand-spraying oil-removing and water-removing pretreatment on the surface, preheating the winding drum in an electric furnace to be 350-400 DEG C, carrying out automatic surfacing with submerged arcs, stopping the surfacing when a surfacing layer reaches 5-6mm, then carrying out slow-cooling treatment, heating the winding drum in the electric furnace to be 400 DEG C, insulating for 2 hours, cooling along with the furnace, and finally forming the winding drum by turning and grinding. The surfacing treatment method has the advantages that the hardness of the winding drum reaches HRC57-60, the wear resistance is good and the service life is long.

Description

technical field [0001] The invention relates to a surface surfacing treatment method for a reel of a wire drawing machine, belonging to the technical field of metal product equipment processing. Background technique [0002] At present, the surface treatment methods of domestic wire drawing machine reels are mainly divided into two types: the first one is the surface quenching of the overall medium and high carbon steel, the general hardness is HRC53-55, the surface hardness is not enough, it is not wear-resistant, and it is easy to groove and affect the product quality. The second is flame spray welding. The reel of the wire drawing machine has the characteristics of large wear-resistant layer area and thin wall (ratio of thickness to diameter: δ / D=0.02). It is easy to deform during spray welding and heating, the quality of spray welding is not easy to control, and the qualified rate of finished products is extremely low.
