The mechanical forced hand-removing device can protect safety of operators in a mould area. The mechanical forced hand-removing device comprises a fixed connecting piece, a shifting fork mechanism, a sliding block connecting fulcrum bar and a hand removing bar. The fixed connecting piece is fixedly arranged on one side portion of a machine body of the press machine. The shifting fork mechanism is hinged on the fixed connecting piece. A long hole or a movement slot is arranged in the shifting fork mechanism. One end of the sliding block connecting fulcrum bar is rotatably arranged in the long hole or the movement slot. The other end of the sliding block connecting fulcrum bar is fixedly arranged on a sliding block. The sliding block connecting fulcrum bar can do translational motion along the long hole or the movement slot. The hand removing bar is connected with the shifting fork mechanism. When the sliding block moves from top to bottom, the hand removing bar moves from the mould area to the outside of the mould area.

Description

Mechanical press is forced row's hand device
Technical field
The utility model relates to a kind of safety guard, and especially a kind of mechanical press is forced row's hand device.
Background technology
The production of punch process is to move up and down in press frame by press ram; the dynamic model that drive is fixed on the slide block impacts downwards; cooperate the part of going out needs processing with cover half on being fixed on press bench by dynamic model; form the district that exerts pressure of product compacting between the dynamic model of punch process and fixed die; blank before the compacted part compacting or part need the operator to send into the mould district that exerts pressure with hand; after compacting, need the operator to take out part with hand in the district that exerts pressure of mould; in the operation of reality; there is not protective device in the mechanical press; need accurately hand to be retracted when dynamic model is depressed by operator's id reaction, just can avoid injury.Obviously, this operator of only depending on to react to avoid dangerous method be very insecure.
The utility model content
Technical problem to be solved in the utility model provides the mechanical press of a kind of operator of protection safety in mould is exerted pressure the zone and forces row's hand device.
The mechanical press that its technical problem that solves the utility model adopts is forced row's hand device, comprises with lower member:
Fixed connecting piece, it is fixedly mounted on the press frame sidepiece;
Shifting fork mechanism, it is hinged on the described fixed connecting piece, is provided with slotted hole or movement slots on it; Shifting fork mechanism is by the slip of pole in slotted hole or movement slots fixing on the slide block, change cleverly the movement locus of shifting fork mechanism, reach the row's hand lever that is connected on the shifting fork mechanism and when slide block down, force operator's the hand that mould is exerted pressure in the district is rejected to the safety zone;
Slide block connects pole, and the end that described slide block connects pole rotatably is installed in the slotted hole or movement slots of shifting fork mechanism, and the other end is fixedly mounted on the slide block, and described slide block connects pole and can slide along slotted hole or movement slots;
Row's hand lever, it is connected on the described shifting fork mechanism, and when slide block moves from top to bottom, exert pressure beyond the zone from mould regional movement to the mould of exerting pressure in effective working end of described row's hand lever.
The beneficial effects of the utility model are: mechanical press forces row's hand device to form chute and linkage after installation, simple in structure, easy to make, do not need extra power resources, the ingenious power that utilizes the mechanical press slide block down, the row's hand lever that drives the row's of pressure hand device by chute and the linkage deathtrap of by force press operation workman's hand discharge pressure machine being exerted pressure, thereby thoroughly solve because equipment breakdown or operator's maloperation cause the possibility that withdraws from the deathtrap when being beyond one's grasp, guarantee the essential safety of mechanical compression machine operation.

Fig. 2 is the schematic diagram that the slide block of mechanical press is positioned at bottom dead centre;
Fig. 3 is schematic diagram of the present utility model;
Parts, position and numbering among the figure: exert pressure zone 12, slide block 2, fixed connecting piece 31, shifting fork mechanism 32, slide block of press frame 1, press frame sidepiece 11, mould connects pole 33, row's hand lever 34, slotted hole 35.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The utility model is installed on the mechanical press, unitary construction as shown in Figure 1, mechanical press comprises press frame 1 and slide block 2, described slide block 2 is arranged in the described press frame 1 and can moves up and down, be provided with the mould zone 12 of exerting pressure in the described press frame 1, the described mould zone of exerting pressure 12 is positioned under the described slide block 2; The utility model comprises: fixed connecting piece 31, and it is fixedly mounted on press frame sidepiece 11; Shifting fork mechanism 32, it is hinged on the described fixed connecting piece 31, is provided with slotted hole 35 or movement slots on it; Slide block connects pole 33, and described slide block connects an end of pole 33 in slotted hole 35 or movement slots, and the other end is fixedly mounted on the described slide block 2, and described slide block connects pole 33 and can slide along slotted hole 35 or movement slots; Row's hand lever 34, it is connected on the described shifting fork mechanism 32, when slide block 2 moves from top to bottom, effective working end of described row's hand lever 34 from mould exert pressure the zone 12 move to mould exert pressure the zone 12 beyond, effectively the working end is namely pushed an end of operator's hand open, the row's of being generally hand lever 34 lower ends are referring to shown in Figure 2.Fixed connecting piece 31 adopts bolt to be installed to press frame sidepiece 11 usually, also can adopt the mode of welding to install.On slide block 2 screwed hole can be set, an end that connects pole 33 at slide block arranges screw thread, is installed on the slide block 2 by screw thread thereby directly slide block is connected pole 33, can certainly directly weld; Slide block connects pole 33 and passes slotted hole 35, and skids off from slotted hole 25 by the anti-limited slip block connection of block piece pole 33 is set in the end, or is installed in the movement slots.Should be noted the angle of regulating row's hand lever 34 when hand lever 34 is installed on the shifting fork mechanism 32 will arranging, thereby so that the movement locus of row's hand lever 34 move to mould and exert pressure beyond the zone 12 from the mould zone 12 of exerting pressure.Concrete connection layout can be with reference to figure 3.
In the course of the work, when slide block 2 is positioned at top dead-centre referring to shown in Figure 1, when needs carry out punch process, slide block 2 moves downward, the slide block connection pole 33 that is connected on the slide block 2 moves downward naturally, drive thus shifting fork mechanism 32 and rotate, and slide block connection this moment pole 33 is slided in slotted hole 35 or movement slots.The i.e. row's of drive hand lever 34 motions of shifting fork mechanism 32, because row's hand lever 24 is to pre-set angle and position, therefore arranging hand lever 24 moves to mould and exerts pressure beyond the zone 12 from the mould zone 12 of exerting pressure gradually, if operator's hand is also in mould is exerted pressure zone 12 at this moment, then will by row hand lever 24 shift onto by force mould exert pressure the zone 12 beyond, avoid injury.When slide block 2 moves to bottom dead centre referring to shown in Figure 2.Equally, after the workpiece punching press was complete, slide block 2 moved upward, and said mechanism is counter motion then, and row's hand lever 24 moves to the mould zone 12 of exerting pressure beyond 12 from the mould zone of exerting pressure gradually.Circulation that so just can be repeatedly guarantees operator's safety.
