Cylinder, drawing clamp holds pipe tightly and carries out drawing, is drawn to before commutating to the second draw trolley clamp by the clamp cam that commutates, and will change
Drawing clamp is set to carry out drawing by drawing clamp oil cylinder on pipe extrusion to the second draw trolley to the hydraulic oil in oil cylinder, the
First, the second draw trolley clamp constantly commutates clamping and release under the rotation of commutation clamp cam, so as to continuously carry out gold
Belong to the drawing of pipe.
, it is necessary to the clamp cam that passes through to commutate makes commutation oil cylinder that hydraulic oil is expressed into drawing on draw trolley in said structure
In clamp oil cylinder, and because the sealing of the oil cylinder that commutates is poor, sealing ring abrasion has easily caused the oily leakage of internal hydraulic pressure, make
Draw trolley upper clamp can not well hold tightly and unclamp, and be skidded in drawing process, so as to have impact on the continuous production of drawbench.
Utility model content
In order to overcome the shortcoming and deficiency of prior art, the utility model provides a kind of connection machine drawing hydraulic control system,
Its discontinuous holding that can efficiently solve the problems, such as draw trolley clamp and release, it is achieved thereby that the continuous life of drawbench
Produce.
Machine drawing hydraulic control system of the present utility model includes multiple drawing clamps being respectively arranged on draw trolley, sets
In the commutation clamp cam of transmission shaft end is coaxially connected with power transmission shaft and corresponding with draw trolley multiple cams, respectively with
Multiple clamp oil cylinders that multiple drawing clamps are correspondingly arranged, Hydraulic Station and the hydraulic circuit being made up of some hydraulic valve pieces, institute
Clamp oil cylinder is stated to be communicated with Hydraulic Station oil circuit；The connection machine drawing hydraulic control system is also included on the commutation clamp cam
Sensor；The hydraulic circuit includes solenoid directional control valve.
Further, the draw trolley, drawing clamp, cam, clamp oil cylinder are respectively equipped with two；The draw trolley
Including the first draw trolley and the second draw trolley；The drawing clamp includes the first drawing clamp and the second drawing clamp；Institute
Stating cam includes the first cam and the second cam；The clamp oil cylinder includes the first clamp oil cylinder and the second clamp oil cylinder.This sets
The hydraulic control system of bigeminy drawing is set to, every group of draw trolley, drawing clamp, cam, clamp oil cylinder cooperate.
Further, the solenoid directional control valve includes the first solenoid directional control valve and the second solenoid directional control valve.Above-mentioned electromagnetism is changed
To valve in hydraulic circuit, the two corresponds to the oil-feed of the oil inlet pipe and the second clamp oil cylinder of the first clamp oil cylinder of control respectively
Pipe.
Further, the sensor includes first sensor and second sensor.Two sensorses are located at the commutation
On the periphery of clamp cam, two steerings of sensing commutation clamp cam respectively, and signal is sent to peripheral control unit, so that
Control the folding of the first solenoid directional control valve and the second solenoid directional control valve.
Compared to existing technology, machine drawing hydraulic control system of the present utility model, by setting sensor and electromagnetic switch
Valve controls the clamping and release of drawing clamp on draw trolley, it is to avoid because of the bad shadow that commutation cylinder seal failure brings
Ring, discontinuous holding and the release of draw trolley clamp are efficiently solved the problems, such as, it is achieved thereby that the continuous production of drawbench.
In order to more fully understand and implement, the utility model is described in detail below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the front view of machine drawing hydraulic control system described in the utility model.
Fig. 2 is the top view of machine drawing hydraulic control system described in the utility model.
Fig. 3 is the side view of machine drawing hydraulic control system described in the utility model.
Specific embodiment
Fig. 1~3 are referred to, is respectively front view, the top view of machine drawing hydraulic control system described in the utility model
And side view.In the present embodiment, the machine drawing hydraulic control system is used for the drawing mechanism that bigeminy is drawn；It includes two difference
Located at the first draw trolley 910 the first drawing clamp and the second drawing clamp on the second draw trolley 920, located at biography
The commutation clamp cam 100 of moving axis shaft end is coaxially connected with power transmission shaft and corresponding with draw trolley the first cam 210 and second
If cam 220, the first clamp oil cylinder being correspondingly arranged with two drawing clamps respectively and the second clamp oil cylinder, Hydraulic Station and by
The hydraulic circuit of dry hydraulic valve piece composition, the clamp oil cylinder is communicated with Hydraulic Station oil circuit.Drawbench passes through hydraulic control system
The continuous clamping and release of drawing clamp are realized, so as to continuously carry out the drawing of pipe.
Specifically, in order that drawing clamp can continuously be clamped and unclamped, the first electromagnetism is provided with the hydraulic circuit
The solenoid directional control valve 720 of reversal valve 710 and second, the two oil inlet pipe 610 and second for corresponding to the first clamp oil cylinder of control respectively is pressed from both sides
Clamp the oil inlet pipe 620 of oil cylinder.The periphery of the commutation clamp cam 100 is provided with first sensor 110 and second sensor
120, the two senses two steerings of commutation clamp cam 100 respectively, and sends signal to peripheral control unit, so as to control first
The folding of the solenoid directional control valve 720 of solenoid directional control valve 710 and second.
When starting the reductor 800 of drawbench, it drives the first cam 210 and the rotation of the second cam 220 and reciprocating linear
Motion, while also driving commutation clamp cam 100 to rotate.But commutation clamp cam 100 is rotated in an anti-clockwise direction along shown in Fig. 3
When, the indicator lamp of first sensor 110 is bright, and solenoid directional control valve 710 is opened, and hydraulic oil enters first and draws by the first oil inlet pipe 510
