Description

Plate spring vertical hardening apparatus controlled by computer

The utility model relates to the vertical device that quenches of a kind of leaf spring, is applicable to the quenching of various vehicles with leaf spring.

Existing leaf spring quenching device, Hydraulic Station, the hoist cylinder five equilibrium is casually arranged with to be put, and floor space is big, and with the work of travel switch control oscillating oil cylinder, failure rate height, the operational process that clamps, loosens workpiece is not steady.

For overcoming above-mentioned shortcoming, the vertical device that quenches of leaf spring that the utility model provides a kind of compact construction, computer control to operate steadily.

Finishing above-mentioned task takes following technical measures to realize: support arm and the former hoist cylinder that is fixed on the base are fixed on respectively between two upright clamping plate, the computer controller that is increased is fixed on the top of upright clamping plate, move to Hydraulic Station near upright clamping plate and be fixed on the base, and the magnetic valve oil path block is fixed on the top of Hydraulic Station, make compact construction like this, floor space reduces greatly; The chute spacing of deciding on the plate is strengthened, make slide plate clamp, loosen operating steadily of workpiece, the magnetic valve oil path block, oil pump, cylinder connector has adopted composite seal, and good sealing effect has fundamentally solved the hydraulic leak problem.

Fig. 1 is a structural representation of the present utility model, Fig. 2 be the A of Fig. 1 to view, Fig. 3 is a basic circuit diagram of the present utility model, Fig. 4 is selection of time switch position figure.

In conjunction with the accompanying drawings structure of the present utility model and embodiment are described as follows:

The utility model is by Hydraulic Station 1, computer controller 2, and solenoid operated directional valve 3, upright clamping plate 4, hoist cylinder 5, oscillating oil cylinder 6, support arm 7, clamping cylinder 8, slide plate 9 and go up tire tooth 9a decide plate 10 and tire tooth 10b composition down.The fixed pivot 7a of support arm 7 and the fixed pivot 5a of hoist cylinder are fixed on respectively between the two upright clamping plate 4, Hydraulic Station 1 is fixed on the base near upright clamping plate 4, the top of Hydraulic Station 1 and solenoid operated directional valve 3 are connected, computer controller 2 is connected with the top of upright clamping plate 4, the piston rod of oscillating oil cylinder 6 and hoist cylinder 5 is facing up with the axle 7b that passes and be fixed on the support arm both sides and is connected, the piston rod of oscillating oil cylinder 6 is facing up and is connected with an axle 6a on deciding plate 10, support arm 7 is facing up and is connected with an axle 7c on deciding plate 10, one end of slide plate 9 and the piston rod of clamping cylinder 8 are connected, the other end and last tire tooth 9a are connected, following tire tooth 10a with decide plate 10 and be connected, the spacing of deciding two chute 10b on the plate 10 has increased by 200 millimeters.Slide plate is being decided on the plate to move clamping to the workpiece leaf spring, is being loosened and operate steadily, between Hydraulic Station 1 and base, solenoid operated directional valve 3 and Hydraulic Station 1, computer controller 2 and the upright clamping plate 4 for being threaded.With the travel switch of the former quenching device of computer controller 2 replacements, be by PC, power switch Ka, starting switch Kb is to the tire K switch _{Tire 1}And K _{Tire 2}, the automatic/hand K switch _FromAnd the reset switch K that links with it ₀, the selection of time K switch ₁And K ₂, 14 line plugs, socket and solenoid operated directional valve CT ₁CT ₇, its output terminal correspondence respectively unclamps 1, clamps 2, and is fuel-displaced 3, goes into oil 4, forward swing 5, and back pendulum 6, high pressure 7 is formed.

Working process of the present utility model is described below:

1. clamp: the workpiece model is put between the upper and lower tire tooth, the Ka that closes a switch, Kb is with K _FromClose computer controller zero clearing, i.e. K ₀Close, at this moment device becomes manually, respectively by K switch _{Tire 1}, K _{Tire 2}, adjust leaf spring and bend to desired arc, then with K switch _FromOpen, the workpiece that heats is put between the upper and lower tire tooth, computer controller 2 work, the starting switch Kb that closes decides program and makes magnetic valve CT by giving in the PC ₂Work, clamping cylinder 8 promote slide plate 9 and go up tire tooth 9a spring plank is clamped,

2. go into oil: after the clamping, decide program, make magnetic valve CT by giving in the PC ₄Work, hoist cylinder 5 is regained, piston rod drives support arm 7 and turns clockwise around fulcrum 7a, drive whole slide plate, decide plate and workpiece enters oil groove downwards around fulcrum 7a by fulcrum 7c, when leaf spring is contacted with pasta in vertical state, the leaf spring both sides contact with oil simultaneously, and cooling is simultaneously shunk, thereby avoid the bent distortion of side.

3. swing: after leaf spring is gone into oil, give in the PC and decide program through CT ₅, CT ₆Control oscillating oil cylinder 8 working in reciprocating mode are swung leaf spring in cooling oil, so that uniform quenching and acceleration cooling,

4. unclamp: according to leaf spring thickness difference, the cool time is also different, by K switch ₁, K ₂Be combined into four kinds of different times (40 seconds, 80 seconds, 160 seconds, 240 seconds) and select, by PC through magnetic valve CT ₁Make the oil circuit of clamping cylinder 8 reverse, last tire tooth 9a unclamps, and leaf spring falls into the oil groove bottom automatically, delivers to tempering stove by the bottom land travelling belt,

5. reset: PC is through magnetic valve CT ₃Fuel-displaced, hoist cylinder 5 is risen, to preceding dead point, make device return to original state, magnetic valve CT through magnetic valve CT5 control oscillating oil cylinder 8 forward swings ₇Be drain charge, overflow magnetic valve, during work (having), overflow, high pressure, when not working (nothing), drain charge, low pressure.

Clamping stroke is 250～300 millimeters, and oscillating stroke is 170 millimeters, and lifting travel is 280 millimeters.

The utility model has the advantages that: 1. structure compactness, floor space is little, has reduced 1/2nd; 2. adopt computer automatically to control failure rate is low; 3. because the slide plate gathering sill is widened, operate steadily; 4. magnetic valve oil path block, oil pump, cylinder connector has adopted composite seal, and good sealing effect has fundamentally solved the Leakage of hydraulic pressure system.
