Description
Technical field
The utility model relates to a kind of protective device, particularly a kind of hydraulic press operation protection device.
Background technology
Hydraulic press is usually used in being used for the pressing process of plastic material; Like thin plate stretching, bending, flange, stamping-out etc., also can be engaged in correction, press-fit, the compression moulding technology of abrasive wheel forming, the moulding of cold-extruded metal parts, plastic products and pulverulent product, along with the development of society; The raising of productivity; The advantage of hydraulic component is more and more obvious, more and more favored by people, thereby is applied in the modern industry more and more widely.Yet during hydraulic machinery equipment situation such as absent minded and board is suddenly out of control operating personnel, security incident takes place easily all.Existing hydraulic machinery safety device adopts electronic safety device to ensure the safe operation of control board more.Yet electronic safety device is because malfunctioning situation takes place in the defective regular meeting of humidity, temperature or electronic device itself, thereby the personal safety that jeopardizes operating personnel.
The utility model content
The utility model technical problem to be solved is, overcomes the defective that prior art exists, and a kind of simple and reasonable, hydraulic press operation protection device of adopting mechanical device protection operator safety is provided.
The utility model addresses the above problem the technical scheme that is adopted: this hydraulic press operation protection device is characterized in that: comprise motion bar on the upper table that is fixed in hydraulic press, be arranged at the chute on the lower table of hydraulic press and place the slide block in the chute, chute is positioned at the below of motion bar; Be provided with the motion bar groove that cooperates with motion bar in the chute; One end of slide block is fixed with pull bar, and the other end of slide block is connected with sliding rope, and sliding rope is connected with the gravity pulling block; Also be rotatablely equipped with the pulley that has groove on the lower table of hydraulic press; Sliding wire clips is gone in the groove of pulley, is provided with stop screw in the chute, and stop screw is fixed in the chute; One end of chute is provided with travel switch, and the control circuit module of travel switch and hydraulic press is electrically connected.
Be equipped with when as above the hydraulic press of the hydraulic press operation protection device of structure is worked, after upper table rose, gravity pulling block pulling pull bar made slide block to front slide; After propping up the stop screw of front, slide block covers the motion bar groove and is positioned at the motion bar below, and this moment, operating personnel can take out workpiece safely; Under the malfunctioning situation of the control of hydraulic press, slide block can bear the downward pressure that upper table drives motion bar, so operating personnel do not worry because the control circuit of hydraulic press is malfunctioning; The upper table that causes descends suddenly, and behind the taking-up workpiece, the pulling pull bar slides backward slide block; Prop up the travel switch of slide block back, transmit the control circuit module of the signal of telecommunication to hydraulic press, the upper table of control hydraulic press descends; Motion bar sinks in the motion bar groove, and hydraulic press carries out punching course.
Be fixed with location-plate on the said chute of the utility model, have locating hole on the location-plate, be inserted with alignment pin in the locating hole, slide block also is provided with locating hole.When hydraulic press did not use, moving slider was to the below of location-plate, and alignment pin inserts the locating hole of slide block and location-plate, plays the fixedly effect of slide block.
The utility model compared with prior art has the following advantages: simple and reasonable, cost is low, installation and easy to operate, and can effectively play the effect of protecting operating personnel's life safety.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the cross-sectional view of A-A on Fig. 1.
