Abstract
A method for machining metal matrix thin-wall diamond bit is characterized in that (1) the components of a formula comprise, by weight, 50%-80% of copper, 2%-15% of tin, 1%-5% of iron, 0.5%-10% of manganese and 5%-40% of cobalt, liquid paraffin accounts for 0.3%-1% of needed power by weight is used as forming wetting agents, and the amount of diamond is determined according to needed concentration; (2) when heating is carried out for sintering, a medium frequency heating induction coil is arranged on a die of the powder part and is arranged in a pressing machine. Temperature is set at 600 DEG C to 900 DEG C, intermittent type induction heating is carried out on the connecting portion of the sintering powder and a base body, pressurization is slowly carried out when the temperature reaches around 500 DEG C until the final pressure reaches 100mpa., the sintering is completed, demolding is carried out after natural cooling, and subsequent machining is carried out. When a drill bit machined through the method is actually used on a punching machine, the times of blade repair by using a repair sheet is reduced, punching efficiency is improved by 15%, continuous punching performance on the punching machine with 5000 revolutions per minute is stable, and the service life is prolonged by 30%.
Description
Technical field
The present invention relates to a kind of manufacture method of metallic bond thin faced bit, in particular for processing the processing of the hollow boring bit of hard brittle material.
Background technology
At present; the processing and fabricating method of metal-base diamond drill bit is to adopt intermediate frequency furnace or resistance furnace hot pressed sintering in protective atmosphere to make; in intermediate frequency furnace and resistance furnace sintering circuit, there is most of heat to be used for heating mould and steel matrix; to make the temperature of whole system reach the temperature of powder sintering; heat time is longer; not only energy consumption is large, and heating process can make adamantine strength decreased affect serviceability for a long time, and single drill bit compacting economic benefit of this manufacture method is low.Has and use high-frequency induction welder hot briquetting, but the bonding agent matrix formula that this technique contains low-melting-point metal (tin, zinc etc.) to some is unfavorable, cause run material and pore many.
Summary of the invention
The present invention is that the technical scheme that solution the problems of the prior art adopt is:
1. formula components and part by weight thereof are: copper 50 ~ 80%, tin 2 ~ 15%, iron 1 ~ 5%, manganese 0.5 ~ 10%, cobalt 5 ~ 40%; Use the atoleine of 0.3% ~ 1% ratio of required powder overall weight as moulding wetting agent, diamond is determined according to the concentration of needs.
2. during heat-agglomerating, heating in medium frequency induction coil is placed in the mould place of powder section, is placed in press.Design temperature is 600 ~ 900 degrees Celsius, and sintering powder and matrix junction are carried out to batch (-type) eddy-current heating, and temperature arrives about 500 degrees Celsius and starts slowly pressurization, and final pressure reaches 100mpa. sintering to be completed, and carries out follow-up machined after natural cooling and demolding.
The specific embodiment
Ingredients by weight ratio is: copper 50 ~ 80%, tin 2 ~ 15%, iron 1 ~ 5%, manganese 0.5 ~ 10%, the matrix formula of cobalt 5 ~ 40%, is used the atoleine of 0.3% ~ 1% ratio of required powder overall weight as moulding wetting agent, and diamond is 60/70 granularity, concentration is 100%, then carries out the operation such as preparation, filler and mould assembling, sintering hot pressing, finished product inspection during manufacture warehouse-in of mixing, matrix and the mould of material.When heat-agglomerating, heating in medium frequency induction coil is placed in the mould place of powder section, is placed in press.Design temperature is 850 degrees Celsius, and sintering powder and matrix junction are carried out to batch (-type) eddy-current heating, and temperature arrives about 500 degrees Celsius and starts slowly pressurization, and final pressure reaches 100mpa.
Product effect: the drill bit of said method processing during actual use, has reduced to use and repaired the number of times that sheet is repaiied sword on puncher, and perforating efficiency has improved 15%, on the drilling machine of 5000 revs/min, the stable performance of punching continuously, the life-span has improved 30%.
