Abstract
The utility model relates to a controlling means of drop hammer testing machine. The control circuit for controlling the positive and negative rotation of the motor of the device consists of two parallel circuits, wherein one branch circuit consists of a button normally open contact SB1 and a normally open auxiliary contact K1 which are connected in parallel and then sequentially connected in series with the normally closed auxiliary contact K3 and a coil L1; the other branch circuit is formed by connecting a button normally-open contact SB2 and a normally-open auxiliary contact K2 in parallel, then sequentially connecting the normally-open auxiliary contact K4 in series and then connecting a coil L2 of an alternating current contactor KM2 in series; the control circuit for controlling the hammer head to release the electromagnet is formed by serially connecting a press buckle switch SB3 and a foot switch SB4 and then serially connecting an electromagnet L, and the serial circuit is connected with the control circuit for controlling the forward and reverse rotation of the motor in parallel. The utility model has the advantages that: the control system is simplified, and the operation of an operator is convenient and quick. Potential safety hazards to a control system due to electromagnetic interference are eliminated, and the failure rate of equipment is reduced.
Description
Technical field
The utility model relates to the control device of the drop hammer tester that the metal material physical test uses.
Background technology
At present, to make the drop hammer tester that enterprise produces all be to be controlled by servomotor to each big testing machine.Its at present each big testing machine to make the drop hammer tester that enterprise produces all be by servomotor control, the main problem that exists: control system is more loaded down with trivial details, failure rate is higher, because there is potential safety hazard in electromagnetic interference (EMI) to control system.
Summary of the invention
The purpose of this utility model provides a kind of control device of safe, easy to operate drop hammer tester.
The utility model is achieved through the following technical solutions:
The control device of drop hammer tester, this device is by motor M, overvoltage protector FR, A.C. contactor KM1, A.C. contactor KM2, air switch QF, the control circuit of control motor positive and inverse, the control circuit of control tup release magnet is formed, the control circuit of described control motor positive and inverse is made up of two parallel circuits, one of them branch road be button normal opened contact SB1 with A.C. contactor KM1 often open auxiliary contact K1 in parallel after, the normally closed auxiliary contact K3 of A.C. contactor KM2 more successively connects, connect the again coil L1 of A.C. contactor KM1 of normally closed auxiliary contact K3 forms; Another branch road is button normal opened contact SB2 with after A.C. contactor KM2 often leaves auxiliary contact K2 parallel connection, connect the again coil L2 of A.C. contactor KM2 of the normally closed auxiliary contact K4 of A.C. contactor KM1, normally closed auxiliary contact K4 that connects successively forms again;
The control circuit of described control tup release magnet is connected in series by push button switch SB3, foot-switch SB4, and series electrical magnet L constitutes again, and the control circuit of this series circuit and above-mentioned control motor positive and inverse is in parallel.
The utility model has the advantages that: simplified control system, make the operator easy to operate, quick.Got rid of because the potential safety hazard that electromagnetic interference (EMI) exists control system reduces equipment failure rate.
Description of drawings
Fig. 1 is control circuit figure of the present utility model.
Embodiment
See Fig. 1, this device changes bridge motor into common electric machine by servomotor, and control system changes push button switch into by servocontrol, and the drive tup rises and descends thereby the control motor just changes, reverses.By a push button switch and the series connection of foot-switch, control tup release magnet, i.e. safety simply again.
Concrete technical scheme is as follows: the control device of drop hammer tester, this device is by motor M, overvoltage protector FR, A.C. contactor KM1, A.C. contactor KM2, air switch QF, the control circuit of control motor positive and inverse, the control circuit of control tup release magnet is formed, it is characterized in that, the control circuit of described control motor positive and inverse is made up of two parallel circuits, one of them branch road be button normal opened contact SB1 with A.C. contactor KM1 often open auxiliary contact K1 in parallel after, the normally closed auxiliary contact K3 of A.C. contactor KM2 more successively connects, connect the again coil L1 of A.C. contactor KM1 of normally closed auxiliary contact K3 forms; Another branch road is button normal opened contact SB2 with after A.C. contactor KM2 often leaves auxiliary contact K2 parallel connection, connect the again coil L2 of A.C. contactor KM2 of the normally closed auxiliary contact K4 of A.C. contactor KM1, normally closed auxiliary contact K4 that connects successively forms again; The control circuit of described control tup release magnet is connected in series by push button switch SB3, foot-switch SB4, and series electrical magnet L constitutes again, and the control circuit of this series circuit and above-mentioned control motor positive and inverse is in parallel.
