Description

Straight line motor drive type radial forging master cylinder guide's servomechanism installation
Technical field
The utility model is related to forging equipment technical field, specifically a kind of straight line motor drive type radial forging Master cylinder guide's servomechanism installation.
Background technology
In forging equipment field, hydraulic radial forging machine is a kind of more tup forging equipments of fast precise, can to it is all The material known carries out forging processing, has pulse concurrently and forges characteristic with multidirectional strike.Existing radial forging master cylinder body Tail portion is axially arranged with switching plug, and switching plug is connected with guide's servo-cylinder, and the synchronism of master cylinder is mainly watched by guide Oil cylinder control is taken, master cylinder piston is servo-actuated.But this guide's servomechanism installation with hydraulic-driven can not meet at present increasingly The production requirement of raising, is mainly manifested in the following aspects:1st, the valve opening and closing in hydraulic pilot servo-cylinder needs to respond Time builds pressure and is also required to time, therefore 300 beats/min of the frequency of highest tup strike currently on the market, and actual production efficiency is low In mechanical radial forging;2nd, the hydraulic system of control hydraulic pilot servo-cylinder cannot ensure multi-cylinder synchronous well at present Property so that forging quality is poor;3rd, it needs specially to be equipped with pioneer pump, control servo valve and corresponding fluid pressure line in hydraulic system, Increase hydraulic system difficulty, increase construction cost;4th, guide's servo-cylinder needs of existing diameter forging machine are integrally purchased from external producer It buys, of high cost, the period is long.
Utility model content
The purpose of this utility model is to provide a kind of radial forging master cylinder guide's servo of linear motor direct drive formula Device is precisely controlled depression stroke and pressing speed when master cylinder piston forges, significantly promotes the forging frequency, solves the same of multi-cylinder The problem of control of step property is difficult, promotes forging quality.
In order to solve the above technical problems, technical solution adopted in the utility model is:
A kind of straight line motor drive type radial forging master cylinder guide's servomechanism installation, it includes forging machine master cylinder piston, master Cylinder cylinder body, switching plug run through the tail portion of master cylinder body, and the tail portion of the master cylinder body is fixedly connected with linear motor pedestal, cuts It changes plug with linear motor sliding block to be connected, linear motor sliding block control switching plug moves forward and backward, and then controls master cylinder Pressurization and off-load.
The working process of the utility model is as follows:
Since the pressure oil in radial direction forging press master cylinder can only flow in one direction, when switching plug is in initial position When, switch the tail portion of plug and master cylinder piston there are gap, pressure oil flows out, without pressure in the rodless cavity of master cylinder body; When linear motor sliding block drives switching plug advance, when switching plug is moved closer to master cylinder piston, the rodless cavity of master cylinder body Oil inlet, pressure gradually increase, and master cylinder piston drives tup to carry out beating forging to forging;When master cylinder piston backhaul, straight-line electric Machine sliding block drives switching plug to retreat, the pressure oil discharge in the rodless cavity of master cylinder body, master cylinder off-load.
The beneficial effects of the utility model are:
The switching plug of the utility model is connected with the sliding block of linear motor, and power, straight line are provided by linear motor Motor has the advantages that velocity interval is wide, response is fast, operates steadily, positioning accuracy is high.It is mounted with the radial direction forging of the utility model Machine is made, depression stroke and pressing speed when master cylinder piston forges can be precisely controlled, control system Synchronization Control can also be passed through The action of multiple master cylinders ensure that the synchronous working of the hydraulic cylinder of radial forging;It, can due to the high speed performance of linear motor The forging frequency is significantly promoted, improves forging quality, reduces forging rejection rate.Linear motor used in the utility model is almost Without abrasion, service life is long, and control is simple.There are many domestic and international producer for producing linear motor, and buying facilitates rapid.

Specific embodiment
The utility model is described further below in conjunction with the accompanying drawings.
A kind of straight line motor drive type radial forging master cylinder guide's servomechanism installation as shown in Figure 2, it includes forging machine Master cylinder piston 1, master cylinder body 2, switching plug 3 run through the tail portion of master cylinder body 1, tail portion and the linear motor bottom of master cylinder body 2 Seat 6 is fixedly connected, and switching plug 3 is connected with linear motor sliding block 7, the advance of the control switching plug 3 of linear motor sliding block 7 with It retreats, and then controls the pressurization and off-load of master cylinder.
The working process of the utility model is as follows:
Since the pressure oil in radial direction forging press master cylinder can only flow in one direction, as shown in figure 3, when switching plug 3 When initial position, there are gap, pressure oil outflow, the nothings of master cylinder body 2 for the tail portion of switching plug 3 and master cylinder piston 1 Without pressure in rod cavity;As shown in figure 4, when linear motor sliding block 7 drives switching plug 3 to advance, switch plug 3 and master cylinder piston 1 when moving closer to and pushing the master cylinder piston 1 to move down, and the rodless cavity oil inlet of master cylinder body 2, pressure gradually increases, and master cylinder is lived 1 drive tup of plug carries out forging to beat forging;As shown in figure 5, when 1 backhaul of master cylinder piston, the drive of linear motor sliding block 7 is cut It changes plug 3 to retreat, the pressure oil discharge in the rodless cavity of master cylinder body 2, master cylinder off-load.
Switch plug in the utility model with the sliding block of linear motor to be connected, power, straight line are provided by linear motor Motor has the advantages that velocity interval is wide, response is fast, operates steadily, positioning accuracy is high.It is mounted with the radial direction forging of the utility model Machine is made, depression stroke and pressing speed when master cylinder piston forges can be precisely controlled, control system Synchronization Control can also be passed through The action of multiple master cylinders ensure that the synchronous working of the hydraulic cylinder of radial forging;It, can due to the high speed performance of linear motor The forging frequency is significantly promoted, improves forging quality, reduces forging rejection rate.Linear motor used in the utility model is almost Without abrasion, service life is long, and control is simple.There are many domestic and international producer for producing linear motor, and buying facilitates rapid.
