Description
Technical field
The utility model relates to the compacting tool set that a kind of mechanical field is used, specifically a kind of compacting tool set of diamond segment.
Background technology
Diamond segment is the operative body of diamond saw blade.The cutter head of diamond saw blade is comprised of diamond and carcass bond, and diamond is a kind of superhard material, plays the effect of cutting edge, and the carcass bond plays the effect of fixed diamond, is made of metal simple-substance powder or metal alloy powders.Adamantine intensity is the important indicator that guarantees the cutter head cutting performance, but the performance of saw blade not merely depends on diamond, but depends on that diamond and binding agent appropriately cooperate the overall performance of this composite of cutter head of formation.
The sintering fusion that is fabricated to the metal dust under pressure of the diamond segment of diamond saw blade is a kind of powder metallurgy process, namely in the diamond segment compacting tool set, metal dust is applied 180-250kgf/cm
2Pressure, and metal dust is under 800 ℃-1000 ℃ high temperature, via series of physical chemical reaction processes such as the diffusion between metal powder granulates, melting welding, chemical combination, recrystallizations, forms the diamond segment with definite profile and machine function.The reeded diamond segment of both sides band in use, cooling water can be brought the cutting workspace into by groove, fully cools off cutter head, improves cutting speed, prolongs the service life of cutter head.
Be divided into two steps during the reeded diamond segment of conventional method processing both sides band: cutter head cold moudling, cutter head are hot-forming.Cutter head cold moudling is the needed shape of straight forming cutter head on cold stamping die, and cold stamping die is comprised of five parts as shown in Figure 1: seaming chuck, push-down head, intermediate plate, front end-plate, end plate.Utilize putting in order of each several part to form required die cavity, in die cavity, add metal dust, under high pressure so that metal dust moulding in cold stamping die; The hot-forming process of cutter head namely is put into the cutter head of cold moudling on the hot pressing die, the HTHP moulding.Hot pressing die comprises five parts: seaming chuck, push-down head, middle plate, end plate, side plate, utilize each several part formation die cavity arranged sequentially, the cutter head of putting into cold moudling places hot pressing die under the HTHP so that the fusion of metal powder of cutter head forms alloy, final molding afterwards.
In the conventional art, the cold moudling process of cutter head is vertical compression, must add intermediate plate and separate two cutter heads, and the shaping efficiency of mould is low; The seaming chuck of cold stamping die, push-down head need to be made into the groove identical with the cutter head shape, and end plate and intermediate plate then need to make the boss opposite with the cutter head groove, Mold Making somewhat expensive; On the cold stamping die with groove, tongue, be unfavorable for that operating personnel take out, transport cutter head and the hot-die of packing into, and cutter head is damaged easily, quality is unstable.Cold stamping die is manual operation, inefficiency and cause easily security incident.
The hot-forming process of cutter head is vertical compression and vertical sinter molding, during the hot pressing die sintering because vertical sintering, need to reeded cutter head according to the groove location of mould one by one correspondence put in, at the bottom of the operating efficiency; Middle plate is arranged when hot-forming, and one-shot forming quantity is very few.The shape of hot pressing die seaming chuck, push-down head and cutter head shape need be consistent, and cause, push-down head is too thin, simultaneously because the material of hot pressing die is graphite, so seaming chuck and push-down head very easily damage, increases the production and processing cost.
The utility model content
The utility model technical issues that need to address provide a kind of under the prerequisite of ensuring the quality of products, the trough of belt diamond segment compacting tool set that can enhance productivity, reduces production costs.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Trough of belt diamond segment compacting tool set comprises diamond segment cold stamping die and trough of belt diamond segment hot pressing die, and described diamond segment cold stamping die comprises former and fits in pressure head to using with former; Described trough of belt diamond segment hot pressing die comprises front end-plate and end plate, and close arrangement has the hot-die that many groups are misplaced and are combined into mutually by seaming chuck, middle pressure head, push-down head between front end-plate and end plate.
Further improvement of the utility model is: the former of described diamond segment cold stamping die be on the excircle with the hollow sleeve of flange, the through hole cross sectional shape of described former is fan-shaped accordingly with cutter head covering of the fan shape; Described pressure head outer surface is corresponding with the through hole of former, and the opposite face of pressure head is the plane, the handle that the pressure head arranged outside is convenient to install.
Further improvement of the utility model is: the seaming chuck of described trough of belt diamond segment hot pressing die, middle pressure head, push-down head shape of cross section be for fan-shaped accordingly with cutter head covering of the fan shape, and the internal end surface of seaming chuck, push-down head and middle pressure head both ends of the surface are the concaveconvex shape corresponding with groove on the cutter head covering of the fan.
Further improvement of the utility model is: described every group mutually the hot-die that is combined into of dislocation combined by pressure head in seaming chuck at two ends and push-down head and between seaming chuck and push-down head several.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
The utility model trough of belt diamond segment compacting tool set comprises diamond segment cold stamping die and trough of belt diamond segment hot pressing die, and when using the utility model to produce the trough of belt diamond segment, flat compressed is adopted in the cold moudling of cutter head; Hot-forming employing flat compressed and plane sintering can guarantee the cutter head quality.
The cutter head of a cold stamping die moulding normal configuration has reduced the mould manufacturing expense, and because do not have reeded shape, prevents breakage, guarantees the cutter head quality of cold moudling.The automatic cold-press mould that adopts can the automatic filling metal dust, automatic moulding and automatic arranging cutter head, realizes that mechanically actuated replaces hand labor, enhances productivity.
Hot pressing die adopts simultaneously moulding of seaming chuck, a plurality of middle pressure head and push-down head trough of belt diamond segment, and each sintering cutter head quantity has improved several times; The thickness of seaming chuck, middle pressure head and push-down head increases, and prevents that the damage of mould from causing production cost to increase.
