Abstract
A spinning forming positioning mechanism for a metal workpiece is used for solving the positioning problem in a spinning process of workpieces. The spinning forming positioning mechanism comprises a base and a supporting body. The base is installed at the spinning pressing sleeve end of metal workpiece spinning equipment through fixing screws, the supporting body and the base are of an integrated structure, and the end face of the supporting body is provided with a limiting groove. According to the spinning forming positioning mechanism, uniformity of axial dimensions after the workpieces are spun is ensured, a quality guarantee is provided for follow-up welding operation of the workpieces, the first-pass yield of welding products is greatly increased, production efficiency is improved, and meanwhile production cost is reduced.
Description
Technical field
The utility model relates to a kind of workpiece locating mechanism, and especially a kind of detent mechanism that is applicable to metallic article end rotary press modelling belongs to metal without Machining Technology for Cutting field.
Background technology
Increasingly stringent along with motor vehicle emission and legislations for noise, Hyundai Motor gas extraction system has all configured external purification annex and noise eliminating silencer, wherein three-way catalytic converter is a kind of external purification means that reduce automotive emissions of current extensive use, when the vehicle exhaust of high temperature passes through purifier, cleanser in catalyst converter will strengthen the activity of CO, HC and tri-kinds of gases of NOX, impel it to carry out redox reaction, pernicious gas is converted into innocuous gas, thereby vehicle exhaust is purified.
Referring to accompanying drawing 1, the housing 1-1 of three-way catalytic converter 1 is the cylindrical shell that two ends are provided with conical tube structure, generally adopts punch welding or flow forming and molding process to produce.Flow forming and molding process is to do lasting feed motion by spinning wheel, stresses on the workpiece pipe rotating, and makes it produce local moulding distortion, is a kind of forming method that is applicable to hollow revolving body.Because flow forming and molding process has, product surface quality is good, stock utilization advantages of higher, and particularly it does not rely on diel, and production flexibility is strong, and processing cost is low, therefore becomes the preferred processing mode of three-way catalytic converter housing.
Referring to accompanying drawing 2～Fig. 5, while utilizing flow forming and molding process processing three-way catalytic converter housing two ends Taper Pipe, first the pipe of having filled the three-way catalytic converter housing 1-1 of cleanser carrier 1-2 be positioned in spinning cover 2 and clamp, then by spinning wheel 3, rotary press modelling being carried out in its one end; Then workpiece is overturn, make its other end be positioned at the outside of spinning cover, utilize spacing striker 4 to adjust after the location of workpiece, workpiece is clamped, then by spinning wheel 3, it is carried out to rotary press modelling; Finally use cutoff tool 5 by unnecessary Partial Resection.In aforesaid operations process, for avoiding spacing striker to cause damage to workpiece, on spacing striker, be provided with buffering flexible member 4-1, therefore exist location of workpiece precision and be difficult to the problem guaranteeing, make after moulding the uniformity of three-way catalytic converter shell 1-1 axial dimension L poor, give and follow-uply cause adverse effect with blast pipe welding sequence.
Utility model content
The purpose of this utility model is the drawback for prior art, provide a kind of simple in structure, easy for installation, can guarantee that rotary press modelling workpiece spindle is to the metallic article rotary press modelling detent mechanism of dimensional accuracy.
Problem described in the utility model realizes with following technical proposals:
A kind of metallic article rotary press modelling detent mechanism, it comprises base and supporter, described base is arranged on the spinning cover blind end of metallic article spinning machine by hold-down screw, described supporter and base are integral type structure, on supporter end face, stopper slot are set.
Above-mentioned metallic article rotary press modelling detent mechanism, described stopper slot is circulus, it mates with the end face of rotary press modelling workpiece.
Above-mentioned metallic article rotary press modelling detent mechanism, described supporter is tubular structure, its external cylindrical surface diameter of phi 2 is greater than workpiece two ends centrum end face outside diameter Φ 1, that is: Φ 2 > Φ 1.
The utility model for three-way catalytic converter housing spinning after the inconsistent problem of axial dimension L, spinning cover inside at existing spinning machine arranges workpiece locating mechanism, installation site while limiting workpiece rotary pressing processing by the stopper slot arranging on supporter end face, thereby guaranteed the uniformity of axial dimension after workpiece spinning, for workpieces in subsequent weld job provides quality assurance, the first-time qualification rate of welding product is promoted greatly, when enhancing productivity, also reduced production cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is three-way catalytic converter structural representation;
Fig. 2～Fig. 5 is existing three-way catalytic converter shell workpiece rotary press modelling process schematic diagram;
Fig. 6 is the spinning cover assembling schematic diagram of the utility model and spinning machine;
Fig. 7 is the utility model structural representation;

In figure, each list of reference numerals is: 1, three-way catalytic converter, 1-1, three-way catalytic converter housing, 1-2, cleanser carrier, 2, the spinning cover of metallic article spinning machine, 3, spinning wheel, 4, spacing striker, 4-1, flexible member, 5, cutoff tool, 6, workpiece rotary press modelling detent mechanism, 6-1, base, 6-2, supporter, 6-3, stopper slot, 7, hold-down screw.
The specific embodiment
Referring to Fig. 6, Fig. 7, the utility model is a kind of workpiece rotary press modelling detent mechanism 6, it comprises base 6-1 and supporter 6-2, the spinning that described base 6-1 is arranged on metallic article spinning machine by hold-down screw 7 overlaps 2 blind ends, described supporter 6-2 and base 6-1 are integral type structure, on supporter 6-2 end face, stopper slot 6-3 are set; Described stopper slot 6-3 is circulus, and it mates with the end face of rotary press modelling workpiece; Described supporter 6-2 is tubular structure, and its external cylindrical surface diameter of phi 2 is greater than workpiece two ends centrum end face outside diameter Φ 1, that is: Φ 2 > Φ 1.
Referring to Fig. 8, the utility model overlaps 2 inside at the spinning of existing spinning machine workpiece rotary press modelling detent mechanism 6 is set, installation site while limiting workpiece rotary pressing processing by the stopper slot 6-3 arranging on supporter 6-2 end face, avoided affecting the location of workpiece precision causing and being difficult to the problem guaranteeing owing to being subject to cushion on spacing striker 4 flexible member 4-1, thereby guaranteed the uniformity of axial dimension L after workpiece spinning.When the utility model is applied to three-way catalytic converter housing 1-1 two ends conical surface rotary press modelling, for follow-up three-way catalytic converter housing 1-1 and blast pipe welding sequence provide quality assurance, the first-time qualification rate of welding product is promoted greatly, when enhancing productivity, also reduced production cost.
