Description
Technical field
The utility model belongs to cold punching die range, more particularly to a kind of explosion-wave-preventing valve deck stretching die
Background technology
Existing explosion-wave-preventing valve deck processing technology is aluminum process, and forming is poor, and appearance is not easy to ensure, workpiece brittleness is big, waste product
Rate is high, and processing technology is complicated, and labor intensity is big, and environmental pollution is serious, inefficiency.A kind of novel cold drawing is researched and developed for this problem
Forming technology stretches aluminium sheet using minute surface overlay film.It is shaped with mold cold drawing, high in machining efficiency, precision is high.
Utility model content
The purpose of this utility model is to be directed to prior art aluminum process, and forming is poor, and appearance is not easy to ensure, workpiece brittleness
Greatly, high rejection rate, processing technology is complicated, and labor intensity is big, and environmental pollution is serious, and the deficiency of inefficiency proposes a kind of explosion-wave-preventing
Valve deck stretching die, which is characterized in that the stretching die includes upper die and lower die and pedestal；Wherein, by elastic discharging device 1, cope plate
2 and cavity plate 3 form upper mold；Lower die is formed by punch-pin 4, lower template 5, material-supporting device 6；Lower die is mounted on pedestal 7；4 elasticity
Discharging device 1 is equidistant to be mounted on 2 middle part of cope plate, and is connect with cavity plate 3 across cope plate 2, and upper mold is coaxially assembled with lower die；
Explosion-wave-preventing valve deck flitch 8 is placed on material-supporting device 6, and cope plate 2 is pressed in above explosion-wave-preventing valve deck flitch 8.
The cavity plate 3, the circular arc of punch-pin 4 are identical as the circular arc of explosion-wave-preventing valve deck.
The punch-pin and cavity plate use the Cr12 alloy tool steels of quenched processing.
The bolster is all made of 45 steel.
The utility model has the beneficial effects that punch-pin and cavity plate use the Cr12 alloy tool steels of quenched processing, mark is executed
Quasi- GB/T1299-1985, intensity is high, has preferable quenching degree and good wearability, suitable to bear smaller impact flexibility, protects
Demonstrate,prove precision；It can be used repeatedly；Mold is once-forming, high in machining efficiency, and precision is high.Bolster uses 45 steel, conditioned place
After reason, obtain higher impact flexibility, plasticity and wearability, be suitable for transmit stamping press, mold under take blame for others material carrying mechanism company
Fixation is connect, is compressed before being stretched for workpiece, upper and lower mould exerts a force simultaneously, and stretcher strain is uniform, while being convenient for controlling hydraulic pressure after stretching
Cylinder moves de- material.Upper mold is elastic stripper, and upper mold carries out automatic material separator using elastic discharging device.

Specific implementation mode
The utility model proposes a kind of explosion-wave-preventing valve deck stretching dies, are explained below in conjunction with the accompanying drawings.
Fig. 1 show explosion-wave-preventing valve deck stretching die structure chart.In figure, which includes upper die and lower die and pedestal；Its
In, upper mold is formed by elastic discharging device 1, cope plate 2 and cavity plate 3；Lower die is formed by punch-pin 4, lower template 5, material-supporting device 6；
The cavity plate 3, the circular arc of punch-pin 4 are identical as the circular arc of explosion-wave-preventing valve deck；Punch-pin and cavity plate are closed using the Cr12 of quenched processing
Golden tool steel；Execution standard GB/T1299-1985, intensity are high, have preferable quenching degree and a good wearability, it is suitable bear compared with
Small impact flexibility ensures precision；The bolster is all made of 45 steel, after conditioned processing, obtain higher impact flexibility,
Plasticity and wearability are suitable for transmitting stamping press；Lower die is mounted on pedestal 7；Discharging device 1 is equidistant is mounted on for 4 elasticity
2 middle part of cope plate, and connect with cavity plate 3 across cope plate 2, upper mold is coaxially assembled with lower die（As shown in Figure 2, Figure 3, Figure 4）；It is anti-
Deflagration wave valve deck flitch 8 is placed on material-supporting device 6, and cope plate 2 is pressed in above explosion-wave-preventing valve deck flitch 8.
Shown in Fig. 5, when work, mold material carrying mechanism of taking blame for others under is connected and fixed, and is assembled in the four column hydraulic pressure taken blame for others under band
On machine, after assembling, explosion-wave-preventing valve deck flitch 8 is placed on material-supporting device 6, and upper mold and lower die coaxially assemble, centering；Cope plate 2
It is pressed in above explosion-wave-preventing valve deck flitch 8.Effect material-supporting device 6 of taking blame for others under controlling first compresses, and controls cylinder up and down and presses simultaneously, draws
It stretches, the oil return material returned of taking blame for others under control, the upper mold automatic rebounding material returned simultaneously removes workpiece and completes a complete process.Mold is primary
Forming, high in machining efficiency, precision is high.The four-column hydraulic press that the utility model is suitable for taking blame for others under band uses.
