The specific embodiment
As shown in Figure 1, the utility model high-vandium steel heat is the pressing mold structure of signing an undertaking all, comprise a counterdie positioning seat 14 and patrix positioning seat 10, be equiped with at least two guide pillars 18 on this counterdie positioning seat 14, the top of this guide pillar 18 is installed in the hole 34 of this patrix positioning seat 10, this patrix positioning seat 10 can be moved back and forth on guide pillar 18, and attach one deck lining 28 around this hole 34, preventing that patrix positioning seat 10 from producing with guide pillar 18 when mobile weares and teares.Between patrix positioning seat 10 and counterdie positioning seat 14, be provided with a drift location-plate 24, a demoulding plate 20 and a punch die 22, wherein, 24 lockings of drift location-plate are in patrix positioning seat 10 lower ends, punch die 22 lockings are on counterdie positioning seat 14, demoulding plate 20 then is located between drift location-plate 24 and the punch die 22, utilize a spring 30 to pass drift location-plate 24 and be locked in the patrix positioning seat 10 times, the strip of desire cutting places this punch die 22 tops.
Aforementioned this drift location-plate 24 and demoulding plate 20 are provided with at least two patrix drift spares 12 and a pilot pin 26, wherein pilot pin 26 still has a segment distance with demoulding plate 20 bottoms, be provided with a lining 32 at patrix drift spare 12 and 20 of demoulding plates, when preventing that patrix drift spare 12 from utilizing spring 30 to move up and down demoulding plate 20 caused wearing and tearing; Then be provided with at least two counterdie drift spares 16 on the punch die 22, the top of this counterdie drift spare 16 is vertical person, it is tiltedly opened down gradually outward, and the counterdie positioning seat of locating under the counterdie drift spare 16 14 is for hollow, its width is slightly wide than counterdie drift spare 16 bottoms, make by the material of patrix drift spare 12 cuttings and discharge, can not be blocked in counterdie drift spare 16 and the hollow position along this hollow position.
When patrix positioning seat 10 drops to the end, the lower end of spring 30 withstands on above the punch die 22, patrix drift spare 12 bottoms just withstand on the top of counterdie drift spare 16, and demoulding plate 20 then just in time is compressed into and touches strip, and this moment, pilot pin 26 did not touch the bottom of demoulding plate 20 as yet.When pilot pin 26 when down punching press is to demoulding plate 20 bottoms again, 12 punching presses of patrix drift spare are to the vertical part in counterdie drift spare 16 tops, and will place the material between demoulding plate 20 and the punch die 22 to cut down, and then utilize spring 30 that demoulding plate 20 is rebounded.
The patrix positioning seat 10 in the utility model and the material of counterdie positioning seat 14 are improved high-vandium steel, it is for adding titanium monoxide in high vanadium alloy comminuted steel shot, to increase its hardness and wearability, wherein high vanadium alloy comminuted steel shot accounts for 60～70 weight portions, best group becomes 65 weight portions, titanium carbide then occupies 30～40 weight portions, and best group becomes 35 weight portions.High vanadium alloy comminuted steel shot is mixed the back add paraffin wax with titanium carbide, after the mixing and ball milling 24 hours, place the oven drying granulation, be pressed into living embryo with mould again, this is given birth to embryo carried out heat-agglomerating one hour, cooled off afterwards, carry out heat with 1200～1300 ℃ of temperature, pressure 1000～2000bar again and all suppress journey with 1300～1400 ℃ temperature, feed gas at last and cool off, and eliminate residual stress in 800～900 ℃ of continuous modes of lonneal for several times.Fig. 2 and Fig. 3 improve the metallograph of high-vandium steel 1400 ℃ and 1450 ℃ sintering temperatures respectively for this reason, find that obviously 1450 ℃ of sintering rear surface holes are low than multi-density, cause hardness low, but after through heat treatments such as quenching, high temperings, hardness can greatly improve, and is even more ideal than 1400 ℃ of sintering persons.Except patrix positioning seat 10 and counterdie positioning seat 14, patrix drift spare 12, counterdie drift spare 16, demoulding plate 20 and punch die 22 also can use the improved high-vandium steel material of this kind, make die life longer.
The utility model high-vandium steel heat all pressing mold structure of signing an undertaking adds titanium carbide in high vanadium alloy steel, with wearability and the corrosion resistance that increases high vanadium alloy steel, utilize through after the specially treated as the material of patrix drift spare and counterdie drift spare, can reach high rigidity, high abrasion, high tenacity, high characteristic such as heat-resisting and anti-corrosion, and then the service life of increase drift, make mould of the present utility model have more practicality.
More than disclosed only be several specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
