Abstract
The utility model relates to the field of die structure design, in particular to a die material jacking device in the field of stamping dies. The die material jacking device comprises a jacking board arranged below a male die, an elastic piece arranged below the jacking board, and a cushion block arranged below the elastic piece, wherein the cushion block is in static connection with a lower die seat, and when the elastic piece is not pressurized by the male die, the upper surface of the jacking board is level and is higher than the horizontal surface of the upmost end of the cutting edge of a blanking concave die. For the die material jacking device, a material jacking manner is adopted for changing the material taking manner of an original die to release the internal space of a lower die seat, so that a fixed seat at the bottom of an insert of the die has an enough space to enhance support, a protruding part subjected to concentrated stress of the die is stressed steadily and is not easy to fracture, and a new thinking is provided for a continuous die blanking manner.
Description
Technical field
The utility model relates to the mould structure design field, specifically, relates to a kind of mould Lifting Device in diel field.
Background technology
In some blanking and piercing die (blanking: utilize stamping-out to obtain the product of certain external form or the process for stamping of blank, purpose is required exterior contour to plate stamping), its blanking part; Traditional form all is downward blanking, but because some shape of product more complicated is convenient for guaranteeing that its product is got material from mold bottom; Die shoe must be reserved enough spaces; Therefore its die plate insert holder has the part ledge unsettled, and do not have enough and support, but because its ledge is stressed more concentrated; Very easily cause holder fracture, thereby make the stressed shakiness of die plate insert and rupture.
Therefore, be necessary to design a kind of device, make that the sheet material after the punching press need not to take out through the overhanging portion of traditional downward discharged way from the die shoe below, but directly take out from the top.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, adapts to practical demand, and a kind of mould Lifting Device is provided.
In order to realize the purpose of the utility model, the technical scheme that the utility model adopts is:
A kind of mould Lifting Device; Comprise the die pad of being located at the punch below; Be located at the elastic component of die pad below, be located at the cushion block of said elastic component below, said cushion block and die shoe static connection; When elastic component does not receive punch pressure, the upper surfaces level of said die pad and be higher than blanking die cutting edge horizontal plane topmost.
Said die pad, elastic component, cushion block be static connection successively from top to bottom.
Be provided with pad between said elastic component and the cushion block.
Said Lifting Device is provided with at least two guiding ducts of passing through die pad, elastic component, cushion block successively; The discharging nail inserts the guiding duct and passes through die pad, elastic component, cushion block from top to bottom successively; The gap that supplies the elastic component compression is left with guiding duct minimum point in the lower end of discharging nail; After elastic component was depressed, the lower end of discharging nail was zero with the pressure of guiding duct minimum point.
The top of said die pad is provided with the dowel hole that is used for workpiece and die pad location.
The beneficial effect of the utility model is:
Change the material mode of getting of original mould with the liftout mode; Liberation die shoe inner space makes its bottom holder of inserting have enough spaces to increase and supports, make its stressed concentrated ledge stressed steadily; Easy fracture provides a new thinking for progressive die discharged way.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Embodiment: referring to Fig. 1.
A kind of mould Lifting Device; Comprise the die pad 1 of being located at the punch below; Be located at the elastic component 2 of die pad 1 below, be located at the cushion block 3 of said elastic component 2 belows, said cushion block 3 and die shoe 4 static connections; When elastic component 2 does not receive punch pressure, the upper surfaces level of said die pad 1 and be higher than blanking die 5 cutting edges horizontal plane topmost.
Said die pad 1, elastic component 2, cushion block 3 static connection successively from top to bottom.
Be provided with pad 6 between said elastic component 2 and the cushion block 3.
Said Lifting Device is provided with at least two guiding ducts 7 of passing through die pad 1, elastic component 2, cushion block 3 successively; Discharging nail 8 inserts guiding duct 7 and passes through die pad 1, elastic component 2, cushion block 3 from top to bottom successively; The gap that supplies elastic component 2 compressions is left with guiding duct 7 minimum points in the lower end of discharging nail 8; After elastic component 2 was depressed, the lower end of discharging nail 8 was zero with the pressure of guiding duct 7 minimum points.
The top of said die pad 1 is provided with the dowel hole that is used for workpiece and die pad 1 location.
The use principle of the utility model is summarized as follows:
Die pad 1 is located at the punch below, workpiece to be processed is positioned on the die pad 1, after putting well; Punch moves downward, and to pressing down, elastic component 2 is compressed with die pad 1; Move downward with die pad 1 and workpiece, behind the completion blanking, punch up moves; Through the screen resilience of elastic component 2, die pad 1 up ejects die cavity with workpiece, because the upper surfaces level of die pad 1 and be higher than blanking die 5 cutting edges horizontal plane topmost; So elastic component 2 can be made die fully with workpiece, the operative employee can take out workpiece very easily from the top.
In the present embodiment, elastic component adopts polyurethane spring, and is common, also can adopt metal coil spring, dish spring etc.The static connection successively from top to bottom of die pad 1, elastic component 2, cushion block 3 can be adopted conventional connected mode such as screw, bonding, welding.
Lifting Device is provided with at least two guiding ducts 7 of passing through die pad 1, elastic component 2, cushion block 3 successively; Discharging nail 8 inserts guiding duct 7 and passes through die pad 1, elastic component 2, cushion block 3 from top to bottom successively; The setting in guiding duct 7; And cooperate with discharging nail 8, can guarantee the accuracy of pressure direction in the punching course, avoid taking place deviation; The gap that supplies elastic component 2 compressions is left with guiding duct 7 minimum points in the lower end of discharging nail 8; After elastic component 2 is depressed; The lower end of discharging nail 8 is zero with the pressure of guiding duct 7 minimum points, i.e. there is the gap all the time in discharging nail lower end or has just contacted but do not had interactional pressure with guiding duct minimum point and exists.
Preferably, the top of said die pad 1 is provided with the dowel hole that is used for workpiece and die pad 1 location., guarantee in the punching course not to make slip, rotation on the workpiece occurred level direction with workpiece and die pad 1 location through alignment pin because of the instantaneous pressure effect.
The utility model includes but not limited to above-mentioned embodiment; Every structural principle is identical with the utility model; Adopt the one or more technical characterictics in the known technology replacement technical scheme, or simple distortion, all drop within the protection domain of the utility model.
