Abstract

The invention discloses a manufacturing method for a long life electroplated diamond bit. A working layer is designed into upper and lower double working layers which are separated by upper and lower waterways. The manufacturing method adopts a secondary feeding groove secondary forming electroplating process and comprises the following steps: electroplating the upper working layer of the electroplated bit by adopting conductive water gap plug 'bridging', adding a common water gap plug in the middle of the working layer and continuously electroplating the lower working layer; and entering inner and outer gauge protection layers of a secondary feeding groove electroplated bit after the operation of electroplating the working layers meets the requirement. The electroplating process comprises the steps of discharging the bit with the electroplated working layers out of the groove, cleaning completely, soaking and preplating in activating preplating liquid, electroplating inner and outer diameters of the electroplating bit in a normal electroplating groove and finishing manufacturing of the bit. The method is unique. According to the method, the effective working layers of the bit are high, the gauge protection effect of the bit can be effectively improved and the adaptability of the bit to the rock stratum is improved, so that the drilling effect of the bit can be obviously improved and the requirements of deep exploration and wire line coring drilling can be met well.

Description

technical field

[0001] The invention relates to a method for manufacturing a drill bit used in the field of geological engineering, in particular to a method for manufacturing a long-life electroplated diamond drill bit. Background technique

[0002] Since entering the 21st century, my country's geological exploration, scientific drilling and deep ore prospecting have developed rapidly. The previous core drilling technology can no longer meet the requirements of modern deep drilling, and the wireline core drilling technology must be vigorously promoted. This requires high-efficiency, long-life diamond drills to match it, otherwise, the wireline core drilling technology cannot be used. The advantages of core drilling will inevitably lead to the consequences of greatly extending the construction period and significantly increasing drilling costs.

[0003] However, the advantage of ordinary electroplated diamond drill bits is high drilling efficiency, but the service life of t...
