Description

High-frequency induction heating pattern riveting device

Technical field

The utility model relates to a kind of high-frequency induction heating pattern riveting device; Belong to chain riveted technical field.

Background technology

At present, the riveted of chain assembling rear pin shaft termination is the termination extrusion angle with bearing pin mostly; With cold stamping processing is convenient feasible, but degree of being connected firmly is relatively poor; For requiring the bigger chain of transferring power, can not reach the serviceability requirement; And the termination of novel excavator chain requirement chain hinge pin is that riveted is the round end shape; Can not reach the designing requirement of chain with original cold punching technology method; Restrict the exploitation of enterprise's new product, new markets, influenced the development of enterprise.

Summary of the invention

In order to overcome above-mentioned deficiency, the purpose of this utility model is to provide a kind of high-frequency induction heating pattern riveting device, adopts high-frequency induction that bearing pin is heated, and locatees with mould; Make the bearing pin riveted reach chain and connect firmly, guarantee bearing pin die quality.

The technical scheme that its technical problem that solves the utility model adopts is: it is given and is stayed process area to form by die shank, upper bolster, upper padding plate, upper mounted plate, riveted patrix, heating collar, roller, preceding backer, die shoe, center counterdie, hex bolts, spring bearer plate, compression spring, activity orientation tongue, back backer, bearing pin; Die shank is contained on the slider of punch, and upper bolster is contained on the die shank, and the riveted patrix is contained on the upper bolster by upper mounted plate and upper padding plate, and slider of punch is enclosed within heating collar on the bearing pin when top dead-centre, is provided with bearing pin at the upper end of bearing pin and gives and stay process area; Preceding backer is contained in the right side of roller, is fixed on the die shoe by hex bolts; Back backer is contained in the left side of roller, and the activity orientation tongue is equipped with in back backer's centre, and the activity orientation tongue stretches in the middle of two rollers, and the activity orientation tongue is fixed by spring bearer plate, compression spring, hex bolts; In the middle of die shoe the center counterdie is housed, bearing pin is stuck in the counterdie of center.

The beneficial effects of the utility model are: adopt high-frequency induction heating pattern riveting device, high-frequency induction heats bearing pin, locatees with mould; With pattern the bearing pin riveted is reached chain and connect firmly, guarantee bearing pin die quality; Reasonable in design, simple in structure, reliable in quality, long service life; Being suitable for large excavator tool etc. uses with chain.
