Problems solved by technology
[0004] However, in the above-mentioned manufacturing process, the sintering machine used is generally a general-purpose sintering machine. Not only is the manufacturing equipment less specialized, but also the number of sinterings at a time is only 4-5, the manufacturing cost is high, and the production efficiency is low. The double test of high pressure results in short service life of graphite mold and high maintenance frequency

Embodiment
[0035] see Figure 1-6, a diamond bit sintering device, including a sintering machine 1, also includes a special press 2, sintering fixed table 3, sintering lifting table 4 and four sintering guide columns 5, sintering lifting table 4 are installed in the sintering machine 1 Slidingly cooperate with the sintering guide column 5 to carry out the sintering operation on the shaped diamond drill bit without customizing the graphite mold, which reduces the production cost. The four sintering guide columns 5 are installed on the one sintering guide column 5 near the right front side. It can realize the automatic loading and unloading of the sintering machine 1. The special press 2 is equipped with a cold pressing fixed table 7, a cold pressing lifting table 8 and four pressing guide columns 9. The cold pressing lifting table 8 and The pressing guide column 9 is in a sliding fit, so that the special press 2 first cold-presses the powder of the diamond particles, which improves the ma...

Description
technical field [0001] The invention relates to the technical field of diamond bit sintering, in particular to a diamond bit sintering device and process. Background technique [0002] The drill bit used as the cutting edge is called a diamond drill bit. The drill bit is an integrated drill bit. The whole drill bit has no moving parts. The structure is relatively simple. It has high strength, high wear resistance and impact resistance. There are many advantages such as less accidents and good well quality. [0003] Existing diamond drill bits usually use a sintering machine in the production process, and a graphite mold is installed on the sintering machine. The production method of the diamond drill bit is generally to first put the powder containing diamond into the cavity of the graphite mold, and use the graphite mold cavity to Matched with graphite blocks, it is made by high temperature and pressure on a sintering machine. [0004] However, in the above-mentioned manu...
