As the flexible member of lower holding pad, the whole existing electromotive signal of mould punching is pneumatically connected signal control, it is necessary to adjust again
Multi-signal coordinates the frequency of lathe, and traditional moulds need to use two kinds of signals of gas circuit and circuit while matched somebody with somebody when using operating pneumatic
Control is closed, the artificial frequency for matching gas circuit signal and lathe, gas circuit power source is related to plant area and equipment, when air pressure fluctuates just
It cannot be guaranteed that the fluency of production；Such as using delay nitrogen spring, after connecting gas circuit, not only need periodically to carry out care and maintenance,
And buying maintenance maintenance cost is high.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of mechanical time-delay mechanism, is connected below cope plate convex
Wheel and limiting buffer post, by the static or motion of the lower holding pad of the rotation control of cam, while pass through the sensing of cam side
Device detects cam position, and automation is realized during punching parts, without artificial matching and debugging, reduces the set-up time, increases mould
The punching press frequency is added while having job stability, saves cost operating efficiency.
To solve problem above, concrete technical scheme of the present utility model is as follows：A kind of mechanical time-delay mechanism, including it is upper
Template, lower template, upper holding pad I and lower holding pad, lower template are provided with nitrogen spring, nitrogen spring upper surface and lower holding pad
Connection, be provided with upper holding pad I above lower holding pad, be connected between upper holding pad I and cope plate caging bolt, guidance set and
Helical springs, are provided with cam sensor position-limit mechanism between cope plate and lower template, cam sensor position-limit mechanism is located at upper holding pad I
Side, cam sensor position-limit mechanism are connected by nitrogen spring with cope plate.
Described cam sensor position-limit mechanism is by cam shaft, upper holding pad II, cam, sensor cluster, limiting buffer
Post I and limiting buffer post II form, and the one end of limiting buffer post I is connected with cope plate, and the lower section of limiting buffer post I is provided with upper pressure
Flitch II, nitrogen spring lower surface are connected with upper holding pad II, and cam shaft is connected with upper holding pad II, limiting buffer post II with
Cam outer rim contacts, and upper holding pad II is located at cam side, sensor cluster is connected with upper holding pad II.
There is distance between axles between described limiting buffer post I and limiting buffer post II, the length of limiting buffer post I is more than spacing slow
Rush the length of post II.
Described caging bolt, guidance set and helical springs diameter parallel.
The described upper surface of upper holding pad II is provided with through hole, lead to the hole site and the position correspondence of limiting buffer post I.
What the utility model was brought has the beneficial effect that：The mould of this design automates in punching course, it is not necessary to artificial
Matching and debugging；Reduce the set-up time, the punching press frequency is added while adding mold work stability, save cost and carry
Operating efficiency is risen.

Embodiment
As shown in figure 1, a kind of mechanical time-delay mechanism, including cope plate 9, lower template 4, upper holding pad I 11 and lower binder
Plate 12, lower template 4 are provided with nitrogen spring 13, and the upper surface of nitrogen spring 13 is connected with lower holding pad 12, the lower top of holding pad 12
Provided with upper holding pad I 11, caging bolt 10, guidance set 8 and helical springs are connected between upper holding pad I 11 and cope plate 9
7, cam sensor position-limit mechanism is provided between cope plate 9 and lower template 4, cam sensor position-limit mechanism is located at upper holding pad I 11 1
Side, cam sensor position-limit mechanism are connected by nitrogen spring 13 with cope plate 9.
Described cam sensor position-limit mechanism is by cam shaft 2, upper holding pad II 14, cam 1, sensor cluster 3, spacing
Bumper post I 5 and limiting buffer post II 6 form, and the one end of limiting buffer post I 5 is connected with cope plate 9, under limiting buffer post I 5
