Embodiment 1

[0053] The following is attached Figure 1-12 The present invention is described in further detail.

[0054] A peeling die device for aluminum welding wire production, such as Figure 1-12 As shown, the installation seat 1 is included, and the inside of the installation seat 1 is provided with a through groove 2, and the inside of the through groove 2 is movably installed with a rolling bearing 8, and the inside of the rolling bearing 8 is fixedly installed with an inner core 10. The inside of the core 10 is movably installed with a die head 11 near one end thereof, and the inside of the inner core 10 is screwed with a top core 13 for tightening the die head 11 near the other end thereof, and the through groove 2 Two limit grooves 17 are symmetrically opened at both ends, and a first end cover 5 and a second end cover 18 that can move laterally along the two limit grooves 17 are installed respectively, and the first end cover 5 is fixedly connected to one end of the rolling ...

Embodiment 2

[0063] The difference from Example 1 is that the inner surface of the welding wire inlet 4, the inner surface of the knife edge 12 and the inner surface of the welding wire channel 15 are all provided with a wear-resistant layer, and the wear-resistant layer is prepared by the following method :

[0064] Take the following raw materials and weigh them by weight: 20 parts of polytetrafluoroethylene, 6 parts of bronze powder, 5 parts of ceramic powder, 15 parts of aluminum oxide powder, 10 parts of chromium oxide particles, 4 parts of film-forming aids, 2 parts of joint agent, 3 parts of defoamer, 2 parts of leveling agent and 40 parts of methanol;

[0065] S1, adding polytetrafluoroethylene, bronze powder, ceramic powder, aluminum oxide powder and chromium oxide particles into a ball mill for fine grinding to obtain a mixed powder material;

[0066] S2. Add the mixed powder material and methanol prepared in step S1 into the reaction kettle and stir for 20 minutes, then add fil...

Embodiment 3

[0073] The difference from Example 2 is the preparation of the wear-resistant layer, and its specific preparation method is as follows:

[0074] Take the following raw materials and weigh them by weight: 25 parts of polytetrafluoroethylene, 8 parts of bronze powder, 7 parts of ceramic powder, 20 parts of aluminum oxide powder, 13 parts of chromium oxide particles, 5 parts of film-forming aids, 4 parts of joint agent, 4 parts of defoamer, 3 parts of leveling agent and 50 parts of methanol;

[0075] S1, adding polytetrafluoroethylene, bronze powder, ceramic powder, aluminum oxide powder and chromium oxide particles into a ball mill for fine grinding to obtain a mixed powder material;

[0076] S2. Add the mixed powder material and methanol prepared in step S1 into the reaction kettle and stir for 25 minutes, then add film-forming aids, coupling agents, defoamers and leveling agents, and continue stirring for 30 minutes, and the stirring speed is set to 800r / min, the temperature...

Abstract

The invention discloses a preparation method of an abrasion resistant layer of a stripping die device. The stripping die device includes a mounting seat, a through groove is formed in the mounting seat, a rolling bearing is movably mounted in the through groove, an inner core is fixedly mounted in the rolling bearing, a die head is movably mounted on the inner part, close to one end part of the rolling bearing, of the inner core, a jacking core is connected with the inner part, close to the other end part, of the rolling bearing, of the inner core in a threaded mode and is used for jacking thedie head, and two limiting grooves are symmetrically formed in the two ends of the through groove correspondingly. The stripping die device for aluminum welding wire production is provided, mountingis convenient, performance is stable, the service life is long, stripping quality is good, the direction of a tool edge is convenient to adjust, the situation that pickling equipment is used for removing oil contamination of the surface of the aluminum welding wire in a traditional technology can be replaced, the defects that the environment is polluted by pickling, and skins of operation staff are prone to being corroded can be overcome, the environmental protection effect is achieved, meanwhile the production cost of the aluminum welding wire can be saved, and the preparation method is worthy promoting and popularizing.

Description

[0001] The invention relates to the technical field of production and processing of a peeling die device, more specifically, it relates to a method for preparing a wear-resistant layer of a peeling die device. Background technique [0002] Welding wire is used as a filler metal or as a wire welding material for electrical conductivity. In gas welding and gas tungsten arc welding, the welding wire is used as filler metal; in submerged arc welding, electroslag welding and other MIG arc welding, the welding wire is both filler metal and conductive electrode. The surface of the welding wire is not coated with anti-oxidation flux. [0003] Aluminum welding wire is a kind of welding wire. During the processing and production of aluminum welding wire, a layer of oil will be generated on its surface. Before leaving the factory, the oil on the surface of aluminum welding wire needs to be removed. The traditional technology is to use pickling equipment to treat the surface of aluminum w...
