Description
Technical Field
The utility model belongs to the technical field of mechanical manufacturing, and particularly relates to a pneumatic safety bolt arranged on an upper cross beam of a press.
Background
The press is main equipment in the punching press production, and the artifical unloading of process of rising in the production process can get into the board, for preventing that slider drop hydro-cylinder piston rod or bolt fracture from causing the slider accident of falling, the press all can be equipped with various safety bolts on the stand, including preventing that the slider from falling the manual safety bolt of fixing on the press stand, pneumatic safety bolt and movable's manual safety bolt, guarantees personal safety. However, the mounting position of the safety plug is not arranged on the upright column of the four-column hydraulic machine, so that the safety plug with a new structure is required to be used for safety protection of the four-column hydraulic machine, and the sliding block falling accident caused by the breakage of the piston rod or the bolt of the oil cylinder in the lifting process of the sliding block is prevented.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is as follows: the pneumatic safety bolt is arranged on an upper cross beam of a press machine and is used for solving the technical problem that the stand column of a four-column hydraulic press is not provided with the mounting position of the safety bolt.
A pneumatic safety bolt arranged on an upper cross beam of a press machine comprises a cylinder with a spring mechanism, a connecting plate, a travel switch, a hook and a clamping plate, wherein the cylinder with the spring mechanism is fixed on the upper cross beam of the press machine through a cylinder base, and the end of a cylinder piston with the spring mechanism is rotatably connected with the upper part of the connecting plate through a pin shaft; the upper end of the connecting plate is in contact with the travel switch, and the lower part of the connecting plate is fixedly connected with the upper end of the hook; the travel switch is fixedly arranged on an upper cross beam of the press machine through a support; the upper part of the hook is connected with the hook base through a rotating pin, and the lower bent part of the hook is clamped with the clamping plate; the hook base is fixedly arranged on an upper cross beam of the press machine; the clamping plate is fixedly arranged on a sliding block of the press machine.
A row of clamping grooves are uniformly distributed on the clamping plate and are sequentially arranged along the vertical direction.
The cylinder with the spring mechanism is a single-acting spring cylinder.
Through the design scheme, the utility model can bring the following beneficial effects:
the utility model fixes the cylinder with the spring mechanism on the upper beam of the press, and can be used universally for presses which have no mounting position of the upright post and have the mounting requirement of the safety bolt. The air cylinder with the spring mechanism controls the hook to be locked or separated from the clamping plate. When the hook is disengaged from the clamping plate, the connecting plate touches the travel switch, and the slide block can descend after the press machine obtains an in-place signal sent by the travel switch; after arriving dead point down, cut off the air supply, the cylinder of taking spring mechanism leans on the spring return stroke, and the couple dies with the cardboard card, and the cardboard backs down the couple when the slider rises and meets the cardboard high point, and the couple is slightly rotatory, and the spring resets in the cylinder when the couple gets into the draw-in groove of cardboard to reach the in-process couple that rises and the cardboard remains the card dead state all the time, the security is high.

Detailed Description
As shown in the figure, the pneumatic safety bolt arranged on the upper cross beam of the press comprises a cylinder 1 with a spring mechanism, a connecting plate 2, a travel switch 3, a hook 4 and a clamping plate 5, wherein the cylinder 1 with the spring mechanism is fixed on the upper cross beam 7 of the press through a cylinder base 6, and the piston end of the cylinder 1 with the spring mechanism is rotatably connected with the upper part of the connecting plate 2 through a pin shaft; the upper end of the connecting plate 2 is in contact with the travel switch 3, and the lower part of the connecting plate 2 is fixedly connected with the upper end of the hook 4; the travel switch 3 is fixedly arranged on an upper cross beam 7 of the press machine through a support 8; the upper part of the hook 4 is connected with a hook base 10 through a rotating pin 9, and the lower bent part of the hook 4 is clamped with the clamping plate 5; the hook base 10 is fixedly arranged on the upper cross beam 7 of the press machine; the clamping plate 5 is fixedly arranged on a sliding block 11 of the press machine.
A row of clamping grooves which are uniformly distributed are arranged on the clamping plate 5, the row of clamping grooves are sequentially arranged along the vertical direction, and the clamping grooves are clamped with the lower bending part of the hook 4.
The cylinder 1 with the spring mechanism is a single-acting spring cylinder.
The specific use method comprises the following steps:
when the sliding block 11 descends, the piston of the cylinder 1 with the spring mechanism retracts, and the connecting plate 2 drives the upper end of the hook 4 to rotate towards the direction close to the cylinder 1 with the spring mechanism by taking the rotating pin 9 as a rotating point, so that the lower bending part of the hook 4 is separated from the clamping plate 5. At the moment, the connecting plate 2 touches the travel switch 3, and the slide block 11 can descend after the press machine obtains an in-place signal sent by the travel switch 3; after slider 11 reachs dead center, cut off the air supply, take spring mechanism's cylinder 1 leans on the spring return stroke, couple 4 and 5 blocks of cardboard die when slider 11 rises, couple 4 is when meetting 5 high points of cardboard, rely on the spring compression in taking spring mechanism's the cylinder 1, cardboard 5 backs down couple 4, couple 4 slightly rotates, spring reset in taking spring mechanism's cylinder 1 when couple 4 gets into cardboard 5's draw-in groove, make couple 4 reset and cardboard 5 block once more die, thereby reach slider 11 rising in-process couple 4 and cardboard 5 and remain the card die state all the time.
