Abstract
The utility model discloses a hydraulic controller for roll-threading machine which mainly comprises a one-way cylinder (2) and an electromagnetic directional valve (3). The electromagnetic directional valve (3) is a three-position electromagnetic directional valve. The body section (1) is provided with a limit switch (5) which is corresponding to a movable roller seat (4), and the electromagnetic directional valve (3) is connected with the limit switch (5). Because the forward and backward travel of the one-way cylinder of the utility model are all carried out through the electromagnet and the limit switch on the both sides of the three-position electromagnetic directional valve, the simple structure, the adjustment is convenient, the blocking valve phenomenon of a unidirectional electromagnetic valve is avoided, and the work efficiency is enhanced.
Description
Technical field:
The utility model relates to a kind of screw-rolling machine hydraulic control device of producing long bolt, bolt etc.
Background technology:
At present, producing the screw-rolling machine that standard component such as long bolt, bolt and non-standard component adopt, its hydraulic control system mainly is to utilize unidirectional oil cylinder that the action roller seat is pushed to the fixed idler whell seat, after the completion of processing, control by two unidirectional solenoid directional control valves, utilize the compression stress of spring to make oil cylinder drive roller mount and retreat, up to roller mount run on the fuselage retreat spacing jackscrew the time, roller mount stops to retreat, and finishes a processing stroke.The position that roller mount retreats is determined by retreating spacing jackscrew, adjusts inconvenience, and, such structure is in fallback procedures, the continuous draining of unidirectional oil cylinder, oil cylinder backward travel are complicated, and oil cylinder needs oil-filled again when starting once more, the oil cylinder working-pressure starting is slow, efficient is low, and two unidirectional electrical magnet valves break down easily, produce the card valve, the processing work efficiency is low.
The utility model content:
It is easy to adjust that the purpose of this utility model is to provide a kind of simple in structure, oil cylinder to retreat, and magnetic valve is not easy to produce fault, the high screw-rolling machine hydraulic control device of processing work efficiency.
For achieving the above object, the utility model mainly comprises unidirectional oil cylinder, solenoid directional control valve, and solenoid directional control valve is the three-position electromagnetic reversal valve, and fuselage is provided with and the corresponding limit switch of action roller seat, and solenoid directional control valve links to each other with limit switch.
As a kind of improvement of the present utility model, be flexible connection between limit switch and fuselage.
The solenoid directional control valve of the utility model screw-rolling machine hydraulic control device is the three-position electromagnetic reversal valve, two side direction electromagnet F1 of magnetic valve, F2 is respectively by forward relay J1, reverse relay J2 control, after hydraulic electric motor starts, move with floor push Hz, forward relay J1 gets electric, the electromagnet F1 adhesive of magnetic valve, oil supply oil supply cylinder, the action roller seat advances, Hz resets when floor push, forward relay J1 dead electricity, and the electromagnet F1 of magnetic valve resets, simultaneously, reverse relay J2, limit switch JK gets electric, the electromagnet F2 adhesive of magnetic valve, oil cylinder draining, the action roller seat retreats, roller mount retreats into limit switch JK operating position, reverse relay J2 dead electricity, limit switch JK dead electricity, the electromagnet F2 of magnetic valve resets, the valve core of magnetic valve is parked in the centre position, and oil cylinder stops to retreat, the no longer oil return of oil cylinder this moment, and be in closed state, finish a process.Because the advancing of unidirectional oil cylinder of the present utility model, backward travel all are to be undertaken by the electromagnet of the both sides of above-mentioned three-position electromagnetic reversal valve and limit switch, and be easy to operate, simple in structure, avoided the card valve phenomenon of unidirectional electrical magnet valve, improved working (machining) efficiency.In addition,, can adjust the position of limit switch easily,, satisfy the processing request of different-diameter screw to adjust the going-back position of action roller seat owing to be flexible connection between limit switch and fuselage.
Description of drawings:
Fig. 1 is the structural representation of the utility model screw-rolling machine hydraulic control device.
Fig. 2 is that A shown in Figure 1 is to view.
Fig. 3 is control device circuit theory diagrams shown in Figure 1.
The specific embodiment:
As shown in Figure 1 and Figure 2, the utility model screw-rolling machine hydraulic control device mainly comprises unidirectional oil cylinder 2 and three-position electromagnetic reversal valve 3, and solenoid directional control valve 3 models can adopt 34E
1-25B, solenoid directional control valve 3 links to each other with limit switch 5 on the fuselage 1, and limit switch 5 can adopt contact-making switch, travel switch or optoelectronic switch, and limit switch 5 is installed on the screw-rolling machine fuselage 1, control the electromagnet of magnetic valve 3 with the position of action roller seat 4, make cylinder action.Between limit switch 5 and the fuselage 1 for flexibly connecting, so that, adjust the position of limit switch 5 according to the processing request of different-diameter screw.As shown in Figure 1, limit switch 5 links to each other with fuselage 1 by an adjustment rack 51, and adjustment rack 51 is fixed on the fuselage 1, has sliding tray 52 on the adjustment rack 51, and limit switch 5 can move along sliding tray 52.Certainly, limit switch 5 also can adopt other mode, and as opposite with said apparatus, limit switch is fixed on the support, is the movable structure of adjusting between support and fuselage.As Fig. 2, shown in Figure 3, magnetic valve 3 is by controls such as motor 7, gear pump 8, overflow valve 6, Pressure gauges 9, two side direction electromagnet F1, the F2 of magnetic valve 3 are controlled by forward relay J1, reverse relay J2 respectively, duty can be divided into semi-automatic operation or operation automatically, by floor push Hz, can control by auto-feed switch, time relay sj when operating automatically during semi-automatic operation.The semi-automatic work Principle of Process is as follows: after hydraulic electric motor D2 starts, with floor push Hz action, forward relay J1 gets electric, the magnetic valve F1 adhesive of advancing, the oil supply oil supply cylinder, the action roller seat advances, and Hz resets when floor push, forward relay J1 dead electricity, the magnetic valve F1 that advances resets, simultaneously, reverse relay J2, JK gets electric, retreats magnetic valve F2 adhesive, the oil cylinder draining, action roller seat 4 retreats, and roller mount 4 retreats into limit switch work JK operating position, reverse relay J2 dead electricity, retreating magnetic valve F2 resets, the valve core of magnetic valve is parked in the center, and oil cylinder stops action, finishes a process.In like manner, when operating automatically,, advance and the intermittent time that retreats can be set as required by time relay sj control.
