Below in conjunction with accompanying drawing, most preferred embodiment of the present invention is further described.
As Fig. 1, shown in 2, a kind of detonation tool note powder charge rising head, this rising head comprises rising head body 1, first core bar 2, push rod 3, second core bar 4 and blaster case 5, first core bar 2 is placed in blaster case 5 with the second core bar 4 is vertical side by side, first core bar 2 and the second core bar 4 width between centers are 16-18mm, first core bar 2 and the second core bar 4 relative blaster case 5 center arrangement, first core bar 2 and the second core bar 4 top end diameter are Φ 6-Φ 10mm, total length tapering is 1: 10, blaster case 5 upper end is opening, first core bar 2 and the second core bar 4 protrude from blaster case 5 upper end 5-8mm, rising head body 1 bottom diameter 0.5-lmm larger than blaster case 5 external diameter, rising head body 1 bottom arranges the first core bar pilot hole 6 respectively, second core bar pilot hole 7, pouring hole 8 and venting hole 9, first core bar pilot hole 6 mates with the first core bar 2, second core bar pilot hole 7 mates with the second core bar 4, pouring hole 8 is positioned on the first core bar pilot hole 6 and the second core bar pilot hole 7 cross central line, distance center 20mm, pouring hole 8 upper end diameter is Φ 15mm, pouring hole 8 lower end diameter is Φ 11mm, center circle on rising head body 1 bottom surface is uniform-distribution with 6-10 venting hole 9, venting hole 9 upper end diameter is Φ 5mm, venting hole 9 lower end diameter is Φ 3mm, rising head body 1 is placed on blaster case 5, and assemble with the first core bar 2 and the second core bar 4, first core bar 2 inserts in the first core bar pilot hole 6, first core bar 2 and the first core bar pilot hole 6 adopt running fit, gap length is 0.1-0.25mm, second core bar 4 inserts in the second core bar pilot hole 7, second core bar 4 and the second core bar pilot hole 7 adopt running fit, gap length is 0.1-0.25mm.Rising head body 1 upper end diameter is 80mm, and the Tapered teeth of rising head body 1 upper end and rising head body 1 bottom is 10-15 °, at rising head body 1,20mm position, bottom is provided with push rod 3.Push rod 3 in this object arranged mainly for making rising head be separated use with powder column during automatic production.When automatic production, powder column, by back mode device jack-up, makes push rod 3 enter in the groove of push-pull device, push-pull device horizontal balance, drives push rod 3 to make rising head body 1 along blaster case 5 central rotation 3-5 °, rising head body 1 is separated with blaster case 5.
First core bar 2, second core bar 4 and rising head body 1 internal surface have employed teflon thermal spraying treatment, and coat-thickness is 15-20 μm; The sectional area sum of venting hole 9 is greater than the 50%-60% of pouring hole 8 sectional area.
Its detailed process is described as follows:
First core bar 2 and the second core bar 4 be assembled in wood pallets be transport agent pallet on, after on artificial collet blaster case 5 being placed on the first core bar 2 and the second core bar 4, then rising head body 1 is inserted the first core bar 2 and the second core bar 4 along the first core bar hole 6 and the second core bar hole 7 and with blaster case 5 matched together.
The 15-20% of blaster case 5 product useful volume of rising head body 1 cavity volume for pouring into a mould, rising head body 1 inner chamber is conical, cone angle is 10-15 °, rising head body 1 lower end and blaster case 5 are mating surface, the degree of depth 15mm of blaster case 5 is inserted in rising head body 1 lower end, object prevents rising head body 1 from coming off from blaster case 5 in wood pallets moving process, and rising head body 1 and blaster case 5 end face close contact also can prevent liquid from flowing out from rising head body 1 lower surface along blaster case 5 sidewall simultaneously.Rising head body 1 bottom surface and blaster case 5 contact jaw face thickness are 2-3mm, this bottom surface is provided with the first core bar pilot hole 6, second core bar pilot hole 7, pouring hole 8 and venting hole 9, wherein the first core bar pilot hole 6 and the second core bar pilot hole 7 respectively with the first core bar 2 and the second core bar 4 running fit.Tolerance clearance puts into the first core bar 2 and the second core bar 4 is advisable so that rising head body 1 is easy and convenient, is generally 0.1-0.25mm.Pouring hole 8 and venting hole 9 are taper hole, cone angle is 90 °, and venting hole 9 arranges 6-10 venting hole 9 according to blaster case 5, is 7 in fig. 2, venting hole 9 lower surface diameter is Φ 3mm, and it is in the center circumferential of Φ 40mm that venting hole 9 is evenly arranged in rising head body 1 basal diameter.Pouring hole 8 lower end diameter is 12mm, 2-5mm larger than the liquid outlet diameter of casting valve, for the sprue channel open of liquid, during cast, liquid is injected bottom blaster case 5 by pouring hole 8 by casting valve, then by slowly rising bottom blaster case 5 until reach required liquid position in rising head body 1.The sectional area sum of all venting holes 9 is greater than the 50%-60% of the sectional area of pouring hole 8.The gas of being more convenient for like this in blaster case 5 is discharged, and avoids forming pore in product.Push rod 3 diameter is 10-15mm, and leaning out rising head body 1 outer diameter length is 20-30mm, and push rod 3 mates with blaster case 5, is arranged on rising head body 1.The setting of push rod 3 is mainly used to move back rising head in automatic production.
The each assembly material of rising head is carbon steel, also can adopt other metallic substance, and surface smoothness is more than 8 class precisions.Rising head body 1 internal surface, the first core bar 2 and the second core bar 4 outside surface entirety adopts Teflon hot-spraying techniques, and coat-thickness is 15-20 μm.Hot-spraying techniques object is adopted to be do not adhere to after ensureing liquid crystallization and freezing, be convenient to being separated of the rising head medicine that produces in rising head body 1 in casting process and rising head body 1, also make the powder column be cast in blaster case 5 exit from the first core bar 2 and the second core bar 4 smoothly.
Rising head of the present invention produces for the artificial note powder charge that detonation tool is traditional some problems existed and a kind of structure of inventing is simple, safe and reliable, the device that can realize automatization continuous prodution, breaches the technical bottleneck of traditional artificial second pouring.Achieve the disposable automatic casting of detonation tool especially by this invention, avoid product and easily form the defects such as shrinkage cavity, pore, coarse crystallization, crackle, ensure that the quality of product, achieve detonation tool production serialization automatization.By adopting riser gating mode to produce detonation tool, improving the work situation that note powder charge is produced, having ensured quality product.Decrease site operation personnel, improve the safety producing equipment, define the novel process that detonation tool cast is produced.
