Description

Punching machine mold explosion-protection equipment
Technical field
The utility model relates to a kind of punching machine mold explosion-protection equipment.
Background technology
User often occurs to cause fracture to fall in die cavity because red needle works long hours in actual production, can not be found in time and punch press carries out punching press continuously, thus cause mould to burst, also and likely by red needle eject simultaneously and the life of operative employee is impacted safely.
Summary of the invention
In order to overcome the deficiency poor without mould explosion prevention function, security of existing punch press, the utility model provides a kind of punching machine mold explosion-protection equipment having mould explosion prevention function, promote security.
The utility model solves the technical scheme that its technical problem adopts:
A kind of punching machine mold explosion-protection equipment, described punching machine mold comprises upper mould fixed plate, stripper plate and lower bolster, described lower bolster is arranged on the lower end of guide post, described upper mould fixed plate and stripper plate can slide up and down suit on the guide bar, described stripper plate is between upper mould fixed plate and lower bolster, linking springs between described cope match-plate pattern fixed head and stripper plate, proximity switch is installed in the bottom surface of described upper mould fixed plate, the end face of described stripper plate installs sensor block, described proximity switch coordinates with described sensor block, described proximity switch with for optionally according to after whether having foreign matter in the signal determining mould of proximity switch stopping the explosion-proof detection module that loop sends control instruction be connected to punch press be anxious.
The beneficial effects of the utility model are mainly manifested in: have mould explosion prevention function, promote security.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of punching machine mold explosion-protection equipment.
Fig. 2 is the circuit diagram of punching machine mold explosion-protection equipment.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
See figures.1.and.2, a kind of punching machine mold explosion-protection equipment, described punching machine mold comprises upper mould fixed plate 1, stripper plate 2 and lower bolster 3, described lower bolster 3 is arranged on the lower end of guide post, described upper mould fixed plate 1 and stripper plate 2 can slide up and down suit on the guide bar, described stripper plate 2 is between upper mould fixed plate 1 and lower bolster 3, linking springs between described cope match-plate pattern fixed head 1 and stripper plate 2, proximity switch 4 is installed in the bottom surface of described upper mould fixed plate 1, the end face of described stripper plate 2 installs sensor block 5, described proximity switch 4 coordinates with described sensor block 5, described proximity switch 4 with for optionally according to after whether having foreign matter in the signal determining mould of proximity switch stopping the explosion-proof detection module that loop sends control instruction be connected to punch press be anxious.
First proximity switch is arranged on the upper mould fixed plate of mould during the installation of this explosion-protection equipment, then sensor block is loaded on stripper plate, as shown in Figure 1.De-material effect is played by spring between upper mould fixed plate and stripper plate, distance when punch press top dead-centre between upper mould fixed plate and stripper plate is maximum, when carrying out mould assembling action when punch press is close to bottom dead centre, stripper plate is first touched lower bolster and is then compressed by the compression spring of punch press, distance between stripper plate and upper mould fixed plate along with punch press close to bottom dead centre by shortening slowly, the punch press angle of operation that sensor block in die cavity during foreign on stripper plate and the proximity switch on cope match-plate pattern start to contact is substantially identical, when only there is foreign matter in die cavity, the contact angle of stripper plate and upper mould fixed plate can shift to an earlier date, therefore we just judge whether have foreign matter in die cavity by the method, protection mould is carried out by setting normal occlusion modular angle degree.
As shown in Figure 2, CAMO is proximity switch, and SA1 is mould explosion prevention function switch.The 24V direct current that V-and V+ provides for punch press, SB1 is SR, and RS1 is electric cam (can arrange 0 to 359 angles to open or close), KA1 and KA2 auxiliary reclay, L1 is mould anti-explosion alarming lamp, and YV1 is punch overload pressure release electromagnetic valve.
This explosion-protection equipment detects angle to judge whether have foreign matter in die cavity mainly through proximity switch, first by SA1 switch opens, set RS1 cam angle degree (establishing method: supposing that proximity switch normal signal exports angle is 160 degree, and it is closed for just RS1 being set to 0 to 159 degree.If) when having foreign matter in die cavity the signal of proximity switch CAMO export angle can by the output within 159 degree in advance that varies in size of foreign matter.Now KA1 closes, and RS1 is also in closure state, the conducting of KA2 relay coil, circuit closed.In the anxious loop of stopping of punch press, KA2 breaks that punch press is anxious to stop, L1 abnormal alarm lamp lights simultaneously, the action of YV1 overload pressure release electromagnetic valve, and discharged fast by the hydraulic oil crossed in slide block, slide block is up pulled back under the effect of balancer.Play and increase again cope match-plate pattern and lower bolster distance while anxious stopping, thus play the effect of duplicate protection mould.Timely stoppage protection and prompting staff fix a breakdown, and what greatly reduce mould falls in die cavity because red needle ruptures the phenomenon leaning on into burst-mode, decreases fault rate and repair a die time and expense.
