Description
Technical field:
The present invention relates to a kind of special equipment of arched spring in use for hydraulic torque converter of car.
Background technology:
Arc spring is mainly used in the automobile torque converter, because its particular performances makes its application in fluid torque-converter more and more widely.The factory of domestic production spring has family more than 4000 approximately, and the spring of production is mainly based on cylindrical, and the plain line of its cylindrical is a straight line, and this spring shape is relatively simple, and domestic existing manufacturing equipment is comparative maturity also, generally can both satisfy this requirement.But the plain line of cylindrical is the arc spring of camber line, and it is more special that manufacturing equipment is required, and the production difficulty is bigger, and the application of arc spring on automobile also is in development at home, and therefore, the producer that has the ability to produce this type of spring is still blank out at present.
Summary of the invention:
The invention provides in a kind of manufacture craft of arched spring in use for hydraulic torque converter of car the arc spring processing special equipment of halting.
The present invention is achieved by the following technical solution: a kind of manufacture craft of arched spring in use for hydraulic torque converter of car is characterized in that the making step of described arc spring is:
Materials procurement → roll into arc → destressing tempering → shot peening strengthening to handle → halt processing → cross grinding → outer rounded corner → dimensional gaughing → performance checking → fatigue life test → surperficial antirust processing → finished product packing;
Wherein step rolls into arc and adopts the digital control computer spring coiling machine, by programme-control spring pitch, steel wire coil is made the basic configuration of arc spring;
Wherein step is halted to handle and is carried out on spring is halted processor, checks free angle, arc radius and pressure and number of times, and pressure direction is for rotating to pressing down fan-shaped exerting pressure;
Two of step cross grinding device therefor grinding wheel belt angles wherein;
Described step is halted and handle to be adopted the special-purpose arc spring processor of halting, a side is provided with bearing block on its base, bearing block connects press rods with pin, the press rods other end connects cylinder by the depression bar connector, press rods is provided with the spiral pressure head from bearing block and arc spring radius same distance place, is provided with down the spiral pressure head from bearing block and arc spring radius same distance place on the base;
The described spiral pressure head of going up is made up of socket lead angle on the mandrel of band rounded nose respectively with following spiral pressure head;
Described base opposite side is provided with " L " shape protection baffle plate.
The invention solves the technical problem of critical process-wind spring, the every performance indications of the arc spring of being produced are met the requirements, used special-purpose arc spring is halted that processor makes between turn and the circle and is tight.
Description of drawings:
Fig. 1 is the halt structural representation of processor of special-purpose arc spring;
Fig. 2 is the structural representation of spiral pressure head up and down.
The specific embodiment:
Technological process is as follows:
1) at first purchases qualified raw material.Because the type spring design stress is higher, and is also higher to the used raw-material performance requirement of spring, therefore, in order to guarantee the quality of product, must be from raw material, product all adopts the raw material of Korea S Kiswire.
2) spring rolls shaping.
Adopt the digital control computer spring coiling machine, by rolling shaping, the basic configuration of spring has just been come out.
3) destressing tempering.
Use the net belt type tempering furnace, the guipure feeding speed is adjustable, and therefore the control of all-electronin instrument can satisfy the production requirement of arc spring.
4) shot peening strengthening operation.
Adopt the mode compressed air shotblasting machine, can be by regulating electric machine frequency, thereby adjust the speed that pellet injection comes out, can also carry out online roller screening to the bullet of the fragmentation that forms in the use in addition, thereby the bullet that guarantees to be ejected into the spring surface is qualified bullet.
The shot peening strength of this device fabrication at present can reach 0.35-0.45A, has satisfied the requirement of spring to shot-peening.
5) processing of halting.
Carry out on spring is halted processor, check free angle, arc radius and pressure and number of times, pressure direction is for rotating to pressing down fan-shaped exerting pressure;
6) cross grinding.
Two emery wheel of spring end grinding machine of domestic production at present is parallel substantially, and charging tray hole axial line is vertical with the wheel grinding face.Be suitable for grinding linear rows spring.For the cross grinding of arc spring, must guarantee that the grinding face of two emery wheels is angled, and can adjust this angle.Simultaneously spring-loaded material hole axial line must with the spring arc anastomosis, could make that like this both ends of the spring obtains grinding on request.
7) outer rounded corner.
Both ends of the spring is after grinding, and cylindrical is a sharp edges, for be convenient to install, and match with the chamfering of installing hole, require the outer rounded corner of bearing coil.
8) dimensional gaughing.
Dimensional gaughing for arc spring, different with the dimensional gaughing of linear pattern spring, the physical dimension of linear pattern spring, can check with slide measure, but arc spring is because its shape is curved, slide measure can only block two points, and these two somes maximum point not necessarily, it is inaccurate therefore to measure numerical value.
9) performance checking.
For the linear pattern spring, the load when its performance checking mainly is its specified altitude assignment of test is straight up and down to test during test, and general spring tension and compression testing machine all can meet the demands.But for arc spring, the performance of its test is the moment of torsion of spring, this and spring duty basically identical.
10) fatigue life test.
Fatigue life test is a simulation spring duty, checks the inherent quality of spring.To spring, be a very important index fatigue life.
11) surperficial antirust processing.For guaranteeing that corrosion phenomena does not take place spring before use, generally can carry out antirust processing, handle finished product.
As Fig. 2, shown in Figure 3, described step is halted and handle to be adopted the special-purpose arc spring processor of halting, a side is provided with bearing block 2 on its base 1, bearing block connects press rods 4 with pin 3, the press rods other end connects cylinder by depression bar connector 6, press rods is provided with spiral pressure head 5 from bearing block and arc spring radius same distance place, is provided with down spiral pressure head 7 from bearing block and arc spring radius same distance place on the base; Last spiral pressure head and following spiral pressure head are made up of socket lead angle 10 on the mandrel 9 of band rounded nose respectively; The base opposite side is provided with " L " shape protection baffle plate 8.
