Abstract
The utility model provides a large-diameter drawing die device of a single acting press. The large-diameter drawing die device comprises an upper flat plate, a lower flat plate, a female die and a male die. The female die is fixed to the lower end face of the upper flat plate. A top plate is arranged on the upper end face of the lower flat plate. The upper end of a top plate is provided with an edge pressing ring and the male die which is arranged inside the edge pressing ring. The periphery of the edge pressing ring is downward pressed to form a shell part when the female die is drawn. One end of an ejector rod abuts against the upper end of a buffer universally applied to machine tools, and the other end of the ejector rod penetrates through the lower flat plate and abuts against the lower end face of the top plate. According to the large-diameter drawing die device, the buffer universally applied to single acting presses is transmitted to the edge pressing ring of a die with the diameter of the extending part larger than the diameter of a bottom hole of a machine tool, and therefore edges of the buffer universally applied to machine tools are pressed, the machining range of the single acting press is enlarged under the condition that the structure of an existing single acting press is not changed, and the large-diameter drawing die device has high practical value.
Description
Technical field
The utility model belongs to technology of die manufacturing field, is specifically related to a kind of single acting press major diameter Stretching die device.
Background technology
On common single acting press, in the time that the diameter of part of extending is greater than lathe bottom outlet, ejector pin of die set spacing dimension exceedes lathe bottom outlet size, push rod position is below punch, on the blank holder of top less than mould, common punch press universal buffer (bullet apical organ) can not be delivered to pressure-pad-force on mould blank holder.And common punch press universal buffer (bullet apical organ) elastic force pressure is large, easily adjust, decrement is large, general, standardization, these advantages can not be used because the diameter of part of extending is greater than lathe bottom outlet, and existing teaching material, professional tool data, technology, in the time of Design of Dies, production, realize pressure-pad-force by design specialized brute spring (or rubber bumper) on mould, or adopt double action press to realize pressure-pad-force.On mould, when design specialized brute spring (or rubber bumper), decrement is little, and fatiguability lost efficacy; Be out of shape excessive, produce plastic deformation, follow the string, produce pressure-pad-force unstable and lost efficacy; Lengthen brute spring (or rubber bumper), will increase the shut height of mould, the shut height of lathe is also claimed; On mould, the pressure-pad-force of special brute spring (or rubber bumper) is difficult to adjust simultaneously, adjust the quantity that pressure-pad-force need to be changed spring or change spring, thick material is extended and is required larger pressure-pad-force, higher to the requirement of special brute spring (or rubber bumper); Use the cost of investment that double action press can great increase equipment, be therefore necessary to propose improvement.
Utility model content
The technical problem that the utility model solves: a kind of single acting press major diameter Stretching die device is provided, by this device, single acting press universal buffer is delivered on the mould blank holder that the diameter of part of extending is greater than lathe bottom outlet, realize the flanging of punch press universal buffer, in the situation that not changing original single acting press structure, expand the range of work of single acting press, there is higher practical value.
The technical solution adopted in the utility model: single acting press major diameter Stretching die device, there is upper flat plate, lower flat board, die and punch, described die is fixed on upper flat plate lower surface, described lower dull and stereotyped upper surface is provided with top board, described top board upper end is provided with blank holder and punch and punch and is placed in blank holder inside, described die presses down blank holder and forms housing zero body around while extending, push rod one end pushes against lathe universal buffer upper end, and the push rod other end pushes against top board lower surface through lower flat board.
Further, described top board diameter is more than or equal to diameter of part to be extended.
Further, described upper flat plate upper surface is provided with the die shank being connected with punch press.
Further, described die and punch are hollow die body, and described top board is solid plate body.
The utility model advantage compared with prior art:
1, while being greater than lathe bottom outlet for the diameter of part of extending, solution cannot be used the problem of lathe universal buffer (bullet apical organ), realize without design specialized brute spring (or rubber bumper) flanging on mould, and make that mould structure is simplified, cost is lower, debugging mould is more prone to;
2, without adopting double action press, do not increase equipment investment or equipment cost, on common single acting press, realize the flanging effect of double action press, in carrying out, low clearance extend Design of Dies, the production of part;
3, can realize the punching press tonnage by lathe, carry out standardized dies design.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is use view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing 1,2, a kind of embodiment of the present utility model is described.
Single acting press major diameter Stretching die device, there is upper flat plate 1, lower dull and stereotyped 2, die 3 and punch 4, described die 3 is fixed on upper flat plate 1 lower surface, described lower dull and stereotyped 2 upper surfaces are provided with top board 5, described top board 5 upper ends are provided with blank holder 6 and punch 4 and punch 4 and are placed in blank holder 6 inside, described die 3 presses down blank holder 6 and forms housing zero body around while extending, push rod 7 one end push against lathe universal buffer 8 upper ends, push rod 7 other ends push against top board 5 lower surfaces through lower dull and stereotyped 2, top board 5 diameters need be more than or equal to diameter of part to be extended, the power of guaranteeing lathe universal buffer 8 is delivered on blank holder 6 part jack-up by push rod 7, described upper flat plate 1 upper surface is provided with the die shank 9 being connected with punch press, described die 3 and punch 4 are hollow die body, described top board 5 is solid plate body.
Adopt after the utility model, in the time that the part diameter of part of extending is greater than lathe bottom diameter, below blank holder 6 and punch 4, design the bridge-type top board 5 of a transmission lathe universal buffer (bullet apical organ) 8 bullet top power, ejector pin of die set 7 spacing are less than lathe bottom diameter, the bullet top power that realizes the universal buffer (bullet apical organ) 8 of lathe is delivered on push rod 7, push rod 7 is delivered to bullet top power on bridge-type top board 8 through lathe fixed flat planar 10, again bullet top power is delivered on mould blank holder 6, realizes the flanging of major diameter Stretching die.The utility model can be by the punching press tonnage of lathe, realizes mould standard design.
Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting the utility model practical range, and the equivalence of being done with content described in the utility model claim therefore all changes, within all should being included in the utility model claim scope.
