As for the device, automatic control replaces the manual operation, and the maintenance operation space of the press is increased; simultaneously, the utility model has the characteristics of safety, reliability and stable movement.

Description

The press ram locking device

Technical field

The utility model relates to a kind of press ram controlling organization, specifically a kind of press ram locking device.

Background technology

Punching machine is in the process of producing, and mould needs frequent finishing up and down, is the personal safety that guarantees in operator's maintenance operation, the unexpected whereabouts of anti-limited slip block, and forcing press all is provided with safety device.Secured fashion commonly used is to adopt safety to fasten, every forcing press is equipped with 2 or 4 safety and fastens, when mould need be repaired, slide block is run to bottom dead centre, and slide block is adjusted to upper limit position, safety is fastened to be placed between workbench and the slide block then, at this moment adjust slide block, make the lower plane of slide block drop on several safety and fasten on the last plane of composition, safety is fastened support slipper, and making has the maintenance operation space below it.The advantage of this kind safety cock is: simple in structure, and low cost of manufacture: but need manual operations, and process is loaded down with trivial details, influences production efficiency, and it is chain to be not suitable for complete machine simultaneously, is unfavorable for realizing the control automation; Because safety cock can only use at the stroke lower limit of forcing press, the space of finishing mould is less.

Summary of the invention

Slide block safety device process hand-manipulated is loaded down with trivial details, service clearance is little and can not realize the problem that automation is controlled in order to solve, the utility model provides a kind of press ram locking device, this device adopts automation control to replace manual operations, improved forcing press maintenance operation space, simultaneously this device have safe and reliable, the characteristics of motion stabilization.

The technical solution of the utility model is: a kind of press ram locking device, comprise entablature, and fixed board on the described entablature, fixing guide groove on the riser is installed with the bearing pin that an end is connected in cylinder on the guide groove sidewall, limit switch is arranged on the cylinder; Guide rod moving up and down is arranged in the guide groove, and the guide rod epimere has the locking hole that cooperates with bearing pin, and hypomere is slide block fixedly.

The beneficial effects of the utility model are: owing to adopt technique scheme, when the guide rod of connection slide block moves up and down in guide groove, cylinder by the band limit switch drives bearing pin, cooperates with the locking hole that is positioned at guide groove inner guide top, reaches the purpose of the slide block that is locked.This device has replaced manual operations by pneumatic automaton; can lock in two positions of top dead-centre of slide block; protection operator's personal safety under the situation that compensating cylinder and brake lost efficacy simultaneously; increased the forcing press automatic controlling level; improved forcing press maintenance operation space; simultaneously this device have safe and reliable, the characteristics of motion stabilization.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Shown in the drawings attached, this press ram locking device comprises entablature 7, and fixed board 6 on the entablature 7, and fixing guide groove 1 on the riser 6 is porose on the sidewall of guide groove 1, is installed with bearing pin 2 in the hole, and an end of bearing pin 2 is connected in cylinder 3, and limit switch 4 is arranged on the cylinder 3; The epimere of guide rod 5 is positioned at guide groove 1, and can move up and down in guide groove 1, and has locking hole 9 to cooperate as shown in Figure 2 with bearing pin 2; And the fixing slide block 8 of guide rod 5 hypomeres.

The locking process is as follows: when slide block 8 runs to top dead-centre, on main controlling board, press corresponding slide block locking button, the ventilation of cylinder 3 one sides, piston is moved to the left, and promotes the locking hole that bearing pin 2 enters guide rod 5 epimeres, guide rod 5 stops to move, thereby will pin with its fixing slide block 8, the back limit switch 4 that puts in place sends signal, and the locking indicator lamp is bright on the main controlling board, show that slide block 8 now is in locking state, forcing press can not carry out other operations; Press corresponding release button on the main controlling board again, the opposite side ventilation of cylinder 3, piston drives bearing pin 2 and moves right, bearing pin 2 shifts out the locking hole 9 on the guide rod 5, guide rod 5 can continue to move in guide groove, and slide block 8 is in free state, and another limit switch 4 of back that puts in place sends signal, it is bright to unclamp indicator lamp on the main controlling board, and forcing press can be operated.This device can be locked in two positions of top dead-centre of slide block, and protection operator's personal safety under the situation that compensating cylinder and brake lost efficacy simultaneously helps the automation control of forcing press complete machine.And the stroke of the sectional area of the diameter of bearing pin 3, guide rod 5 and guide groove, cylinder and cylinder thrust are determined after should taking into full account the weight that slide block adds patrix.

Claims (1)

1, a kind of press ram locking device, comprise entablature (7), it is characterized in that: fixed board on the entablature (6), riser (6) is gone up fixedly guide groove (1), be installed with an end on guide groove (1) sidewall and be connected in the bearing pin (2) of cylinder (3), limit switch (4) is arranged on the cylinder (3); Guide rod moving up and down (5) is arranged in the guide groove (1), and guide rod (5) epimere has the locking hole (9) that cooperates with bearing pin (2), and the fixing slide block (8) of hypomere.
