Abstract
The utility model discloses a kind of protection device of punching machine mold; including punch press lathe bed, punch press drift, controller, current vortex sensor and metal sensor block; current vortex sensor is arranged on punch press lathe bed; metal sensor block is arranged on punch press drift side; and metal sensor block and current vortex sensor are up and down vertical opposite; current vortex sensor is electrically connected with the controller, and controller is electrically connected by relay with punch press circuit for controlling motor.During mold work, when there is part or stamping material is overlapping, the protection device can make punch press autostop, to avoid the damage of diel.
Description
Technical field
The protection device of mould is the utility model is related to, is particularly wall-mounted on the diel on punch press in punching parts mistake
The device protected in journey to the mould.
Background technology
Diel on punch press is in the punching course of part, sometimes due to the demoulding that fails, it may appear that
Part or the overlapping situation of stamping material, because punch press running frequency is generally higher, operating personnel are difficult to timely discovery processing,
The damage of mould is easily caused if working on.
The content of the invention
The purpose of this utility model is to provide a kind of protection device of punching machine mold, during mold work, works as appearance
When part or overlapping stamping material, punch press can autostop, to avoid the damage of diel.
The protection device of punching machine mold described in the utility model, including punch press lathe bed and punch press drift, in addition to controller,
Current vortex sensor and metal sensor block, current vortex sensor are arranged on punch press lathe bed or on work bench of punch press, metal sensing
Block is arranged on punch press drift side, and metal sensor block and current vortex sensor are up and down vertical opposite, current vortex sensor and control
Device electrical connection processed, controller are electrically connected by relay with punch press circuit for controlling motor.
During normal ram, when punch press drift is run to lower position, metal sensor block and current vortex sensor it
Between distance be 2~4mm.
Controller is prior art products, and electricity is controlled by 12V or 24V direct-current switch power supplies module, display circuit and mainboard
Road forms, and has program chip in main board control circuit, whole device is controlled.
During normal ram, punch press drift is from bottom dead centre（Extreme lower position of the drift in punching course）Run up supreme dead
Point（Peak）After come again downwards to minimum point complete a press cycle.
When there are two parts or overlapping two pieces of stamping materials, the minimum point that the operation of punch press drift can reach is not
The bottom dead centre of punch press drift during normal ram, punch press drift when the lowest point that punch press drift can reach is than normal ram
Lower dead point position it is high.
Be provided with the program for judging and controlling in the controller, its constantly detect with calculate current vortex sensor with
The distance between metal sensor block, when punch press drift is run to extreme lower position in each press cycle（It is not necessarily lower dead
Point）, just it is compared with default current vortex sensor with the distance between metal sensor block value scope.
During normal ram, punch press drift from top dead-centre run to bottom dead centre when, current vortex sensor is by itself and gold
The distance between category sensor block is transferred to controller by voltage signal, and controller carries out translation operation to signal with judging, this
When the distance between current vortex sensor and metal sensor block in normal range of set value, controller will not be sent to relay
Action signal, punch press continue normal work.When there are two parts or overlapping two pieces of stamping materials, punch press drift is run to
During minimum point（The bottom dead centre of drift when this position is not normal ram）, the distance between current vortex sensor and metal sensor block
More than normal range of set value, the action of controller control relay, punch press circuit for controlling motor is disconnected, shuts down punch press.
The utility model is due to that with this kind of structure, can sense the extreme lower position that drift is reached in punch press running
Whether in the range of normal position, when sensing that the extreme lower position is in normal range (NR), punch press can continue to run；And work as and be somebody's turn to do
When extreme lower position exceedes normal range (NR), punch press hard stop can be made, so that mould exempts from damage, realize the automatic of mould
Protection.The utility model is simple in construction, is quick on the draw, reliable operation.
Brief description of the drawings
Fig. 1 is the schematic front view of the protection device of punching machine mold described in the utility model；
Fig. 2 is control principle module map of the present utility model.
Embodiment
In order to which the technical solution of the utility model is explained further, the utility model is explained in detail below in conjunction with the accompanying drawings
State.
As depicted in figs. 1 and 2, the protection device of the punching machine mold includes punch press lathe bed 2, punch press drift 6, and controller
4th, current vortex sensor 3 and metal sensor block 1, current vortex sensor 3 are arranged on work bench of punch press 5, and metal sensor block 1 is installed
In the side of punch press drift 6, and metal sensor block 1 and current vortex sensor 3 are up and down vertical opposite, during normal ram, punching
When bed drift 6 is run to lower position, the distance between metal sensor block 1 and current vortex sensor 3 are 2~4mm.Current vortex passes
Sensor 3 is electrically connected with controller 4, and controller 4 is electrically connected by relay with punch press circuit for controlling motor.
During normal ram, punch press drift 6 from top dead-centre run to bottom dead centre when, current vortex sensor 3 by its with
The distance between metal sensor block 1 is transferred to controller 4 by voltage signal, and controller 4 carries out translation operation to signal with sentencing
It is disconnected, and shown current vortex sensor 3 and the distance between metal sensor block 1 value by display, now current vortex passes
In normal range of set value, controller 4 will not send action letter to relay for the distance between sensor 3 and metal sensor block 1
Number, punch press continues normal work.When there are two parts or overlapping two pieces of stamping materials, punch press drift 6 runs to minimum
During point（The bottom dead centre of drift when this position is not normal ram）, the distance between current vortex sensor 3 and metal sensor block 1 are big
In normal range of set value, the action of the control relay of controller 4, punch press circuit for controlling motor is disconnected, shuts down punch press.
In the present embodiment, current vortex sensor 3 can be also arranged on punch press lathe bed 2, and it is new that this practicality equally can be achieved
The purpose of type.
