Abstract
The utility model discloses a hard alloy rivet punching mould which is characterized by comprising two parts, wherein a hard alloy groove part at the front end and an alloy steel 3Cr2W8v handle part on the rear portion are integrally welded in an embedded mode. Compared with the prior art, the hard alloy rivet punching mould has the advantages that an original rivet punching mould turns red after contentiously punching five rivets, phenomena of rivet sticking, annealing or rupture occur, about four hundred rivet punching moulds are used every month, consumption is large, and demand exceeds supply; if the hard alloy rivet punching mould is used, a couple of hard alloy rivet punching moulds are used every month, dozens of hard alloy rivet punching moulds are used every year, the problems of rivet sticking, rupture, poor forming of an R part of a rivet are solved, product quality is improved, normal production is ensured, and tool cost is reduced.
Description
Technical field
The utility model belongs to trolley coach manufacturing technology field, relates to position hot riveting and other various larger hot riveting parts such as rail vehicle traction beam, core dish.
Background technology
The whole material that all adopts of an original rivet steamed bread of corn is high-speed steel (3Cr2w8v), a steamed bread of corn that uses this material manufacturing is the pressure rivet deliquescing that just reddens for 10 times service life, causes annealing, then fracture and sticking nail phenomenon, reduced product quality, the puzzlement manufacturing schedule.
The utility model content
The purpose of this utility model provides a kind of high temperature resistant, unannealed, antiseized nail, an anti-fracture rivet steamed bread of corn, reaches service life 1000 times, solves long-term puzzlement and produces, and affects the difficult problem of product quality.
For achieving the above object, the utility model provides an a kind of carbide alloy rivet steamed bread of corn, it is characterized in that: minute two parts, front end carbide alloy groove position and back steel alloy 3Cr2W8v shank welding-on are integrated.
The advantage that the utility model has with respect to prior art: original continuous 5 rivets of riveting, a rivet steamed bread of corn has just reddened, and sticking nail annealing or phenomenon of rupture just occur, a rivet steamed bread of corn is per month with regard to handy about 400, consume especially bigly, supply falls short of demand, uses a carbide alloy rivet steamed bread of corn, use per month several, use tens in 1 year, and solved sticking nail, fracture, the bad problem of rivet R section moulding, improved product quality, guarantee normal production, reduce tool expense.
Description of drawings
Accompanying drawing 1 is structure chart of the present utility model.
The specific embodiment
With reference to accompanying drawing, shank 1 uses steel alloy 3Cr2W8v to make, and front end concave part 2 uses the carbide alloy manufacturing.Front end concave part 2 and shank 1 inlayed be welding as one, form overall structure.The effect of shank 1 is the clamping for rivet driver, and front end concave part 2 is working portions.
