Description
Technical field
The present invention relates to a kind of quenching apparatus, be specifically related to a kind of quenching of steel plate spring feed mechanism.
Background technology
Plate spring plate spring is most widely used a kind of elastic element in automotive suspension, and it is wide by some but the elastic beam of the approximately equi-strength that the alloy spring sheet of Length discrepancy (thickness can be equal, also can be unequal) combines.Automobile leaf spring, as a kind of important automobile suspension system, has consequence in the production application of automobile.Plate spring production process mainly comprises: fracture, boring, grasswort and Bao Er, bending forming, quenching, tempering and the step such as to spray paint.
Quenching is more than workpiece heat to critical temperature, after making it austenitizing, then is greater than the quick refrigeration of critical cooling velocity after held for some time, thus obtains the treatment process of martensitic stucture.Quenching is the technique of more complicated in thermal treatment, is also to give steel with the key job of final performance.Plate spring mainly enters in oil groove and leaves standstill by common quenching apparatus, and this quenching mode is not only consuming time, and plate spring consistence of quenching everywhere is poor.
Summary of the invention
For the defect that above-mentioned prior art exists, the object of the present invention is to provide a kind of quenching consuming time short, the quenching of steel plate spring feed mechanism that quenching rear spring consistence is good.
For achieving the above object, technical scheme of the present invention is:
Quenching of steel plate spring feed mechanism, wherein, comprise support, oscillating oil cylinder, clamping cylinder, holder, oil cylinder seat, fixation clip and movable pressing board, be articulated with in the middle part of described holder on support, described clamping cylinder is fixed on holder side by oil cylinder seat, described movable pressing board is connected with the piston rod of clamping cylinder, described fixation clip is connected on the holder of holder away from clamping cylinder one end, and it is positioned opposite with movable pressing board, described oscillating oil cylinder and support hinged, the piston rod of oscillating oil cylinder and holder hinged near clamping cylinder side.
When adopting technique scheme, first plate spring to be quenched is placed between fixation clip and movable pressing board, control clamping cylinder oil-feed, the piston rod of clamping cylinder is stretched out, plate spring to be quenched is clamped on fixation clip, then two oil supply holes controlling oscillating oil cylinder replace oil-feed, due to hinged with support in the middle part of holder, so clockwise, the counterclockwise alternatively swinging of the pin joint of holder in the middle part of it, the plate spring being now clamped in holder side then swings up and down quenching in oil groove.After plate spring to be quenched is immersed the hardening liquid in oil groove by the present invention, oscillating oil cylinder drives holder to swing up and down, plate spring quenching process in hardening liquid is mobile, quenching process can be accelerated, and plate spring is in moving process, uniform quenching everywhere, so the consistence of quenching rear spring is good.
Further, described holder is positioned at clamping cylinder side and is provided with balancing weight.Plate spring is clamped at holder away from clamping cylinder side, the heavier-weight of this side, if exerted a force by oscillating oil cylinder completely, then oscillating oil cylinder easily damages, and arranges the burden that balancing weight can alleviate oscillating oil cylinder.
Further, the position of described holder between fixation clip and movable pressing board is provided with locating slot.During clamping plate spring, be first placed in locating slot by plate spring, the movement of restriction plate spring, can prevent plate spring from sliding like this, depart from clamped position.
Further, described fixation clip clamping plate spring one side is for coordinating plate spring inner concave arc surface, and movable pressing board clamping plate spring side is the arc surface coordinating plate spring inner concave.When plate spring clamps by movable pressing board and fixation clip, the area of clamping is large, and clamping is stable, and plate spring uniform force.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of quenching of steel plate spring feed mechanism embodiment of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
As shown in Figure 1, a kind of quenching of steel plate spring feed mechanism, wherein, comprise support 1, oscillating oil cylinder 2, clamping cylinder 3, holder 4, oil cylinder seat 5, fixation clip 6 and movable pressing board 7, be articulated with on support 1 in the middle part of holder 4, clamping cylinder 3 is fixed on holder 4 side by oil cylinder seat 5, movable pressing board 7 is connected with the piston rod of clamping cylinder 3, fixation clip 6 is connected on the holder 4 of holder 4 away from clamping cylinder 3 one end, and it is positioned opposite with movable pressing board 7, oscillating oil cylinder 2 is hinged with support 1, the piston rod of oscillating oil cylinder 2 and holder 4 hinged near clamping cylinder 3 side.
In the present embodiment, holder 4 is positioned at clamping cylinder 3 side and is provided with balancing weight 8.Plate spring is clamped at holder 4 away from clamping cylinder 3 side, the heavier-weight of this side, if exerted a force by oscillating oil cylinder 2 completely, then oscillating oil cylinder 2 easily damages, and arranges the burden that balancing weight 8 can alleviate oscillating oil cylinder 2.
The position of holder 4 between fixation clip 6 and movable pressing board 7 is provided with locating slot 41.During clamping plate spring, be first placed on by plate spring in locating slot 41, the movement of restriction plate spring, can prevent plate spring from sliding like this, depart from clamped position.
Fixation clip 6 clamps plate spring one side for coordinating plate spring inner concave arc surface 61, and it is the arc surface 71 coordinating plate spring inner concave that movable pressing board 7 clamps plate spring side.When plate spring clamps by movable pressing board 7 and fixation clip 6, the area of clamping is large, and clamping is stable, and plate spring uniform force.
Specific works principle:
As shown in Figure 1, first plate spring to be quenched is placed between fixation clip 6 and movable pressing board 7, control clamping cylinder 3 oil-feed, the piston rod of clamping cylinder 3 is stretched out, plate spring to be quenched is clamped on fixation clip 6, then two oil supply holes controlling oscillating oil cylinder 2 replace oil-feed, due to hinged with support 1 in the middle part of holder 4, so clockwise, the counterclockwise alternatively swinging of the pin joint of holder 4 in the middle part of it, the plate spring being now clamped in holder 4 side then swings up and down quenching in oil groove.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification sheets etc. record the content that may be used for explaining claim.
