Abstract

A kind of cold extrusion novel die, it is combined by plug and runner, plug is connect with servo motor, runner is mounted on the main shaft of cold extrusion equipment, ring groove on runner periphery connect fit shapes with processed product and matches, processed product is rotated with the plug same direction, and runner is rotated with plug opposite direction.First product cold extrusion is processed with extrusion die, after machine-shaping, then turning is carried out to allowance, original is changed completely with turnery processing to cutter requirement height, low production efficiency, a series of problem is brought to enterprise's production, the production of enterprise product is influenced, becomes the bottleneck project of Vehicle Processing production.The allowance that turning extrusion die is now only needed to be left after processing, greatly reduce the turnery processing amount 50~75% of product at Vehicle Processing dustproof groove and wall thickness, and turning and chip removal are smooth, improve cutter life 20~30%, production efficiency 15~25% is improved, thoroughly solve and captures the bottleneck that turnery processing is difficult, processing influences production slowly.

Description

Cold extrusion novel die

Technical field

The utility model is related to a kind of cold extrusion die for processing, particularly a kind of to be used to process bearing and other cold extrusions The cold extrusion novel die of product.

Background technology

Since cold extrusion Bearing inner tissue streamline is different from mill run and hardness high tenacity is good, structure type adaptability By force, therefore at home and abroad in various machineries, particularly high-end vehicles and precise machining equipment, aircraft, superior automobile, more and more extensively The bearing processed with such method is used generally.

Bearing material hardness height, good toughness, difficult processing, it is particularly complex-shaped at wall thickness and dustproof groove, to Lathe quantity The process tool requirement of big bearing ring is high, and cutter life low also easy crushing knife, therefore low production efficiency, becomes vehicle and adds The bottleneck project of work, influences the production of enterprise.

The patent No. 201420728840.5 " hub bearing lasso extrusion die " provides one kind and increases one before extrusion Road pre-heating technique substitutes heating in medium frequency warm forging, realizes that the extruding preheating of link-up operation and the hub bearing lasso of extrusion molding are given birth to Production improves work efficiency, quality, reduces manufacture cost.

Invention content

Technical problem to be solved in the utility model is：A kind of cold extrusion novel die is provided, first with mold to product Preliminary working is carried out, product basic configuration is processed, then allowance is machined again, solve and only brought with Vehicle Processing Difficult processing, the slow production problem of processing, especially the Lathe quantity of dustproof groove complicated shape is greatly reduced, cold extrusion die rigidity By force, stability is good, service life is long.

The technical scheme in the invention for solving the above technical problem is：Cold extrusion novel die, by plug and with treating The runner of converted products cooperation is combined into, and the plug is connect with servo motor, and the runner is mounted on the master of cold extrusion equipment On axis, the ring groove on runner periphery connect cooperation with processed product, shape matches, the plug and processed product phase Equidirectional rotation, the runner are rotated with plug opposite direction.

Compared with prior art, the utility model has the advantage of：Cold extrusion novel die will carry dustproof groove originally It is modified to first process the cold extrusion of lasso with cold extrusion die by the method for turnery processing completely at bearing ring and wall thickness, Turning is carried out to allowance again after machine-shaping, former turning completely is changed to cutter requirement height, low production efficiency, to enterprise Production brings a series of problem, influences the production of enterprise product, becomes the bottleneck project of Vehicle Processing production, now only needs turning cold The allowance left after extrusion die processing, greatly reduces the turnery processing amount 50~75% at Vehicle Processing dustproof groove and wall thickness, And turning and chip removal are smooth, cutter life improves 20~30%, and production efficiency significantly improves 15~25%, thoroughly solves and captures Difficult processing, the slow bottleneck for influencing production of processing.

Specific embodiment

The embodiment of the utility model is further described below in conjunction with the accompanying drawings.

Plug 7 is shaped according to the type of processed bearing ring and other products, shape, screw hole thereon, centre bore, branch Strut size is consistent, is designed according to the width of product, dust-proof trough curvature, ditch diameter, internal diameter, surplus and phase at plug dustproof groove Angle, plug width, the draft angle answered are corresponding with assembling die, avoid burr occur between mold.

The upper end of plug 7 is supporting rod 2, has threaded hole 1 on the top surface of supporting rod, is connected in cold extrusion equipment with it, Other end foot piece is connect with servo motor.

The endoporus 11 of runner 10 is connected on the main shaft of cold extrusion equipment, the shape of 10 periphery ring groove 9 of runner with it is to be added Chemical product shape matches, and now connect cooperation, and shape matches for bearing ring 8 with processed product, bearing ring 8 and core The equidirectional rotation together of stick 7, runner 10 are rotated with 7 opposite direction of plug.

The outer diameter of plug 7, at 15~25 degree, makes plug 7 be docked with runner 10 and is not easy with the draft angle 3 of 10 intersection of runner Burr and overlap are generated, to reduce the Vehicle Processing amount at 8 dustproof groove of bearing ring, is designed with the inclined-plane that inclination angle is 15~25 degree 4, the molding position of plug 7 is by 6 rounding off of raceway circular arc on the symmetrical inclined-plane 4 in both sides, transition arc 5 and centre, combination It is formed into the similar W-shaped curvilinear plane that processed product shape matches.

Before cold extrusion, if processed product is bearing ring 8, the ring being sent on 10 outer periphery of runner by manipulator is recessed In slot 9, plug 7 does not enter bearing ring 8 also, as shown in Figure 2.

During work, runner is driven by main shaft, and servo motor pushes plug 7 to be rotated towards with runner opposite direction, bearing ring 8 With 7 equidirectional rotation of plug, the raceway groove and dustproof groove contour line of bearing outer ring all it is machined go out, as shown in figure 3, cold extrusion works It completes, as shown in Figure 4.

Plug 7 is exited from from 1 end of screw hole, and servo motor retreats, and the ring that bearing ring 8 is left by gravity on runner 10 is recessed Slot 9 falls into hopper, completes the cold extrusion processing of a bearing ring.

Vehicle Processing is entered back into, the bearing ring 8 of extrusion forming adds according to institute's made allowance after cold extrusion into driving again Work greatly reduces Lathe quantity 50~75%, thus solve the problems, such as the former difficult processing brought completely by Vehicle Processing, process it is slow, Thoroughly change the former bottleneck project for influencing production, greatly improve production efficiency 15~25%.
