Abstract
The utility model relates to a pre-strengthening apparatus for railway elastic bars. The utility model comprises a host and a hydraulic device, and the host is composed of a working platform, a hydraulic cylinder and a prepressing device. The utility model is characterized in that the hydraulic device is connected with the hydraulic cylinder on the host through a hydraulic pipe; the prepressing device is fixed on the working platform, and the prepressing device is connected with the hydraulic cylinder through a piston rod. The utility model can analyze and test railway elastic bars which have defects, the production quality of the elastic bars can be ensured, the residual deformation can be eliminated, the shapes of the elastic bars can be stabilized, and the residual compressive stress can be added. The use reliability and the fatigue life of the elastic bars can be improved, and the service life of the elastic bars can be extended.
Description
The utility model relates to a kind of hydraulic pressure electromechanical integration equipment, particularly a kind of equipment that can carry out pre-intensive treatment to railway elastic bar.
Railway elastic bar is the important component of railway, and the application life of this class A of geometric unitA and reliability are direct and safety of railway transportation is closely related.For a long time, produce spring and generally all adopt following operation: 1. blanking; 2. contact electrical heating; 3. thermoforming; 4. immediate quenching; 5. tempering; 6. water-cooled; 7. paint; 8. put in storage.Perhaps 1. blankings; 2. cold forming; 3. heating; 4. quench; 5. tempering; 6. water-cooled; 7. paint; 8. put in storage.Relatively poor with the spring reliability that this operation is produced, often at the initial stage of using, many springs can not use with regard to fracture takes place.The main cause that causes this phenomenon is the spring of being produced, it is out of question that the surface seems, and in fact inside exists defective, above-mentioned technology can't make such spring go-on-go come out, also can not be to the spring additional hardening, make to exist the spring of quality problems to come into operation, cause unnecessary economic loss.
The purpose of this utility model just provides a kind of pre-strengthening device of railway elastic bar, and it can further strengthen spring detecting the railway elastic bar while that has defective, improves the quality of production of spring, prolongs the application life of spring.
The purpose of this utility model is to realize by such technical scheme, it includes main frame and hydraulic means, main frame is made up of working platform, hydraulic cylinder and prepressing device, hydraulic means links to each other with hydraulic cylinder on the main frame by hydraulic tube, prepressing device is fixed on the working platform, and is connected with hydraulic cylinder by piston rod.
Before spring paints warehouse-in, with the utility model spring is carried out once pre-intensive treatment, being about to spring is put in the prepressing device, by hydraulic means, hydraulic cylinder and prepressing device spring is carried out precompressed, if there is defective in spring, fracture or crack will appear after the precompressed, at this moment will rupture or the rejecting of crannied spring, and still intact spring enters the operation of paint warehouse-in after the precompressed, thereby has improved the outgoing of spring.In order to guarantee the finished size of the spring after the pre-intensive treatment, in the design of spring moulding form, should make spring increase certain sagitta, can eliminate the spring residual strain after the precompressed, produce additional hardening, improve the fatigue life of spring, prolong the application life of spring.
Owing to adopted technique scheme, the utlity model has following advantage:
1, can divide and detect the railway elastic bar that has defective, guarantee the quality of production of spring;
2, eliminate residual strain, stablize the spring shape;
3, increase residual compressive stress, improve the reliability that spring uses;
4, improve the fatigue life of spring, prolonged the application life of spring;
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of prepressing device.
Among the figure: 1. main frame; 2. hydraulic means; 3. working platform; 4. hydraulic cylinder; 5. prepressing device; 6. hydraulic tube; 7. piston rod; 8. base plate; 9. fender bracket; 10. supporting seat; 11. spring; 12. lead; 13. guiding platen; 14. pilot hole; 15. precompressed hole; 16. pre-pressure head; 17. variable duplex pump.
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model includes main frame 1 and hydraulic means 2, main frame 1 is made up of working platform 3, hydraulic cylinder 4 and prepressing device 5, hydraulic means 2 links to each other with hydraulic cylinder 4 on the main frame 1 by hydraulic tube 6, prepressing device 5 is fixed on the working platform 3, and is connected with hydraulic cylinder 4 by piston rod 7.
Before spring paints warehouse-in, with the utility model spring is carried out once pre-intensive treatment, being about to spring is put in the prepressing device 5, carry out precompressed by hydraulic means 2, hydraulic cylinder 4 and 5 pairs of springs of prepressing device, if there is defective in spring, fracture or crack will appear after the precompressed, at this moment will rupture or the rejecting of crannied spring, and still intact spring enters the operation of paint warehouse-in after the precompressed, thereby has improved the outgoing of spring.In order to guarantee the finished size of the spring after the pre-intensive treatment, in the design of spring moulding form, should make spring increase certain sagitta, can eliminate the spring residual strain after the precompressed, produce additional hardening, improve the fatigue life of spring, prolong the application life of spring.
As shown in Figure 2; prepressing device 5 is supporting seats 10 of idiozona fender bracket 9 on base plate 8; fender bracket 9 tops fix with lead 12 1 ends that are with spring 11; lead 12 other ends pass the pilot hole 14 on the guiding platen 13 with hydraulic fluid rod 7 bottom Joints movably; have precompressed hole 15 at fender bracket 9 tops, it is affixed with piston rod 7 that pre-pressure head 16 passes precompressed hole 15.Hurt sb.'s feelings in order to prevent that spring from breaking to eject, be provided with fender bracket 9 on the prepressing device; The effect of spring 11 is to be convenient to make pre-pressure head 16 to reset; The effect of lead is that piston rod and pre-pressure head are moved vertically.
Hydraulic means 2 is hydraulic presses of band variable duplex pump 17, so that the loading velocity of control precompressed.
