Abstract
A process for preparing the serially stringed diamond beads includes such steps as proportionally mixing raw materials, granulating, die pressing to obtain raw bead, preparing core body, inserting it in the inner hole of raw bead, and non-pressure sintering.
Description
Technical field
The present invention relates to a kind of manufacture method of the saw of restricting, in particular to a kind of manufacture method of diamond bead.
Background technology
In the prior art, the rope saw is started late in China, and the way of electroplating inlaying or hot pressed sintering is mostly adopted in beading production, though adopt the galvanoplastic production technology simple, but metal lining is limited to durability of diamond, and diamond comes off easily in advance, and because of the thin partially life-span weak point of working lining.Adopt the hot pressed sintering rule to cause very big difficulty in operation, reason is the working lining wall thin (about 1.5mm) of beading, belongs to long tube thin-walled parts, has any problem in charging, heating, and production efficiency is low, and the daily output is lower than 400.
Summary of the invention
Technical problem to be solved by this invention is to avoid above-mentioned deficiency of the prior art, and a kind of manufacture method of diamond bead is proposed, and the diamond bead long service life of using this method to produce, simple to operate, the production efficiency height can be produced the rope saw and push mass to.
Technical scheme provided by the present invention is: a kind of manufacture method of diamond bead is characterized in that it comprises the following steps:
(1) metal dust is prepared burden in proportion, it is dried mixed to put into batch mixer then, adds diamond and binding agent, and wet mixing mixes it, produces the single-size material by granulator;
(2) weighing, each material chamber is 3-5g, with the particulate material that the weighs up cold stamping die material chamber of packing into, is pressed into tool bit green with hydraulic press, pressure is monodentate 8～11MPa, pressurize 5～8 seconds;
(3) core body that processes is inserted the tool bit green endoporus, put into the graphite cuvette frame, bury with graphite powder, then at the sintering kiln roasting, sintering temperature is 840～860 ℃, and the time is 60～90 minutes, with the stove cooling, comes out of the stove, and removes graphite powder and promptly gets beading.
Enter previous step ground, the described dry blend time is 30～60 minutes, and the wet mixed feed time is 50-80 minute.
Further, described cold stamping die is many drifts monoblock type, once suppresses 8～12 cutter heads.
Further, interporal lacuna is 0.01～0.03 millimeter in described core outside diameter and the tool bit green, 2.5～4 millimeters of internal diameters, high 8～10 millimeters annulus, core surface copper facing.
Further, described sintering furnace is the continuous oven of colding pressing with gas shield and salband.
In above-mentioned manufacture method, in the step (1), when wherein preparing burden, metal dust can be selected as required, and ratio also can change.
The present invention has following advantage: utilize the inventive method can improve the production efficiency of diamond bead significantly, the daily output can reach more than 1000, simple to operate, reduce production procedure, reduce operation easier, can produce the rope saw and push mass to, and, the long service life of these beading can prolong 25%.
Description of drawings
Fig. 1 is the process chart of diamond bead manufacture method of the present invention.
The specific embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention.
Diamond bead manufacture method of the present invention is as follows:
Referring to Fig. 1, metal dust is prepared burden in proportion, in the present embodiment, metal dust is Co and Ni, Co and Ni join 1 kilogram by weight 4: 1 ratio, in another embodiment, also can select other powder, prepare burden in required ratio.Then the metal powder material for preparing is put into GM130 three-dimensional blender machine and do to be mixed 30 minutes, add diamond particles 60 grams again and be that 60% isopropyl alcohol prepares 100 milliliters of binding agents with concentration, wet mixing 50 minutes makes it even, makes graininess with the GA180 granulator.Weigh 12 parts of the particulate material that make in the balance, every part 4.2 gram is pack into 10 millimeters of diameters of particulate material, core hole 6
0 + 0.025Many drifts monoblock type cold stamping die (model is MS.T10-100) material chamber of millimeter, swing die makes particulate material closely knit, the YH32-200A hydraulic press transferred to cause monodentate pressure be 8MPa,, 6 seconds of pressurize, be pressed into tool bit green, tool bit green is cylindrical, external diameter 10mm, internal diameter 6mm, height 8mm suppresses 12 at every turn.Steel pipe or round steel are processed into external diameter 6
-0.03 -0.01Millimeter, 3 millimeters of endoporus, long 9 millimeters core body, copper facing is inserted the tool bit green endoporus to core body then, and tool bit green of string is put into the graphite cuvette frame on each core body, buries with graphite powder; The graphite cuvette frame is put into the continuous sintering kiln roasting of colding pressing that has hydrogen shield, 840 ℃ of heating-up temperatures, the time is 90 minutes, the cutter head powder is bonded to core body with the reaction and the powder contraction acting in conjunction of core surface copper.With the stove cooling, come out of the stove, remove graphite powder and promptly get beading.
