Abstract
The utility model discloses a safety plug device of a medium- and small- scale hydraulic press, which comprises a lower cross beam of the hydraulic press, wherein, an upright post, a bracket, a rotating arm and a safety plug are mounted in the diagonal positions of the lower cross beam; the position of the safety plug can be adjusted; the length of the safety plug depends on the opening of the hydraulic press; a limit switch is mounted on the bracket; and a relative link stopper is mounted on the rotating arm. A main frame can work normally only when the link stopper is in contact with the limit switch. When a slide block returns to an upper limit position after finishing an operation, the main frame is power-off; the rotating arm of the safety plug is pushed to rotate around the center of a rotating shaft until the safety plug is pushed between the slide block and the lower cross beam; and the link stopper on the rotating arm is separated from the limit switch to be interlocked with the main frame. The utility model which applies a safety plug device in a medium- and small- scale hydraulic press, has the advantages that the safety of the hydraulic press and operators can be absolutely ensured during the replacement of the hydraulic press in any condition.
Description
Technical field:
The utility model relates to hydraulic press safety servicing unit, the safety cock device of more specifically saying so and being applied in middle-size and small-size hydraulic press.
Background technology:
At present known in large-scale single action hydraulic sheet metal drawing press, slide block is arranged at the upper limit locking device, there is not the position that the manufacturing cost condition with higher is installed but in middle-size and small-size single action hydraulic sheet metal drawing press, exist.
Summary of the invention:
The utility model is for avoiding above-mentioned existing in prior technology weak point, be provided at the safety cock device in the middle-size and small-size hydraulic press, can make hydraulic press in the process of mold exchange, guarantee operator's personal safety, and manufacturing cost being lower.
The technical scheme that the utility model technical solution problem is adopted is:
The safety cock device of middle-size and small-size hydraulic press, include the hydraulic press sill, it is characterized in that being installed with column at the sidewall of sill, support is installed on the column, horizontal pivoted arm is installed on the support, be connected with turning cylinder between pivoted arm and support, rotate at the pivoted arm moving axis center that can rotate, described pivoted arm front end has sleeve, is set with safety cock in the described sleeve, and the safety cock upper end is set with spring, be positioned at the sleeve top, be separately installed with upper and lower locating piece on the safety cock, last locating piece presses the spring upper end, and following locating piece retaining is in the sleeve lower end.
The safety cock device of described middle-size and small-size hydraulic press is characterized in that on the described support limit switch being installed, and the collision block corresponding with limit switch is installed on the described pivoted arm.
The safety cock device of described middle-size and small-size hydraulic press is characterized in that described column is positioned at the diagonal position of sill.
When safety cock was subjected to downward pressure, spring was compressed, and safety cock moves down and touches sill; When downward pressure removes, then under the spring force effect, moving up of safety cock restPoses.The length of safety cock is according to the opening decision of hydraulic press.
Limit switch also is housed on support, collision block is housed on pivoted arm.Have only collision block to contact, main frame ability operate as normal with limit switch; When slide block work finishes when getting back to upper limit, the main frame outage, the operator rotates with the pivoted arm of the handgrip safety cock moving axis center that rotates, and up to safety cock is pushed between slide block and the sill, makes that collision block breaks away from limit switch on the pivoted arm, forms with main frame and interlocks.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model adopts the safety cock device, can make hydraulic press in the process of mold exchange, and what's going on no matter all can definitely guarantee hydraulic press and operator's safety.This advanced person simple in structure, easy to operate.
Description of drawings:
Accompanying drawing 1 (a) and (b), (c) are installed in the location drawing of main frame for the safety cock of middle-size and small-size hydraulic press.
Accompanying drawing 2 is the safety cock structure chart of middle-size and small-size hydraulic press.
Number in the figure: locating piece on 1 column, 2 limit switches, 3 supports, 4 turning cylinders, 5 pivoted arms, 6 collision blocks, 7,8 springs, 9 times locating pieces, 10 safety cocks, 11, slide block, 12 sills
Below in conjunction with accompanying drawing, and the utility model is described in further detail to pass through the specific embodiment.
The specific embodiment:
Referring to accompanying drawing.
The safety cock device of middle-size and small-size hydraulic press, include hydraulic press sill 12, there is slider of hydraulic press 11 entablature 12 tops, the sidewall diagonal position of sill is installed with column 1, support 3 is installed on the column 1, horizontal pivoted arm 5 is installed on the support 3,3 on pivoted arm 5 and support are connected with turning cylinder 4, and rotate at pivoted arm 5 moving axis 4 centers that can rotate, and pivoted arm 5 front ends have sleeve, be set with safety cock 10 in the sleeve, safety cock 10 upper ends are set with spring 8, are positioned at the sleeve top, are separately installed with on the safety cock 10, following locating piece 7,9, last locating piece 7 presses spring 8 upper ends, and following locating piece 9 retainings are in the sleeve lower end.Limit switch 2 is installed on the support 3, the collision block 6 corresponding with limit switch 2 is installed on the pivoted arm 5.
In the concrete operations, when slide block 11 work finishes when getting back to upper limit, the main frame outage, the operator at first adjusts the lower end of safety cock 10 apart from sill 15MM, and the upper end of safety cock 10 is adjusted apart from slide block 30-40MM.The operator rotates the pivoted arm 5 of safety cock 10 moving axis 4 centers that rotate with hand, up to safety cock 10 is pushed between slide block 11 and the sill 12, makes that collision block 6 breaks away from limit switches 2 on the pivoted arm 5, interlocks with main frame formation.If this moment, slide block 11 had the downslide phenomenon, slide block 11 is the upper end of touch-safe bolt 10 at first, and compression spring 8 makes the lower end of safety cock 10 contact with sill 12, and safety cock played support slipper 11 and acted on this moment, protected operator's life safety.
In the time of need reworking, make slide block 11 backhauls to upper limit, safety cock 10 is got back to the home position under the effect of spring 8, and the operator makes safety cock 10 withdraw from main frame with hand, and making collision block 6 on the pivoted arm 5 with after the limit switch 2 of support 3 contacts, main frame could operate as normal.
