Energy-saving composite plate pressing device

Abstract

The invention discloses an energy-saving composite sheet pressing device, which comprises a main body of a polycrystalline diamond composite sheet, a connection part is arranged under the main body of the polycrystalline diamond composite sheet, and convex ribs are arranged on the top of the main body of the polycrystalline diamond composite sheet , the surface of the polycrystalline diamond compact body is provided with an impact-resistant alloy layer, the lower layer of the impact-resistant alloy layer is provided with high heat-resistant polycrystalline diamond, and the lower layer of the high heat-resistant polycrystalline diamond is provided There is polycrystalline diamond, the polycrystalline diamond inner layer is provided with a transition layer. The invention is beneficial to enhance the ability of the composite sheet to penetrate into the formation, and the convex ribs make the cutting surface have a strong plowing effect, which reduces the drilling and cutting resistance, thereby increasing the ROP of the diamond drill bit, and the transition layer reduces the heat between the bonding surfaces. Residual stress, thereby improving the impact toughness of polycrystalline diamond, improving the quality of polycrystalline diamond, prolonging the service life, eliminating the need for frequent replacement, and being more energy-saving and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of diamond equipment, in particular to an energy-saving composite sheet pressing device. Background technique [0002] Diamond is commonly known as "diamond". That is what we often call the original body of diamond. It is a mineral composed of carbon, a particle substance composed of simple elements in nature, and an allotrope of carbon. [0003] The traditional polycrystalline diamond composite sheet has weak pressure bearing capacity, low rock breaking efficiency, weak impact resistance, short service life, frequent replacement, waste of resources, not conducive to energy saving and environmental protection, and high maintenance cost. Using this polycrystalline diamond composite sheet The ROP is low, so we propose an energy-saving composite sheet pressing device to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to provide an energy-saving composite ...
