Embodiment Construction
[0036] Below in conjunction with embodiment the present invention is described in further detail:
[0037] Step A, according to the use of the diamond cutter head, put the metal powder containing copper, tin, iron, nickel, cobalt and diamond particles into the mixer according to the proportion and mix them evenly, put the mixed powder into the container and Carry out sealing; Here container selects the stainless steel airtight container that is not easy to be oxidized.
[0038] Step B, open the container for the powder, and pour a certain amount of powder into the cutter head cold press according to the number of cutter heads to be produced and press it into the shape of the cutter head; clean the cold press before starting the pressing to prevent these residues from affecting the composition of the cutter head. In addition, 3 to 5 pieces should be pressed for testing before formal production. If the pressed cutter head does not meet the requirements, various parameters in th...

The invention discloses a diamond tool bit production process based on vacuum cooling equipment and belongs to the field of tool manufacturing. The diamond tool bit production process comprises the following steps: step A, putting a metal powder material and diamond particles in a mixer according to a proportion, uniformly mixing and then sealing; step B, pouring a certain amount of powder material into a tool bit cold press according to the quantity of to-be-produced tool bits and pressing to form the shape of a tool bit; step C, putting each press-molded tool bit into a graphite mold, fastening the molds through bolts, and subsequently sintering the graphite molds in which the tool bits are arranged, in a sintering machine; step D, after sintering is ended, cooling the graphite molds in which the diamond tool bits are arranged, in the vacuum cooling equipment; step E, after cooling is ended, dismounting the tool bits from the corresponding graphite molds. According to the production process disclosed by the invention, the tool bits are cooled inside the vacuum cooling equipment, so the performances of each diamond tool bit are greatly improved, and the service life of the graphite molds is prolonged. The production process disclosed by the invention also has the advantages of saving labor, saving energy, being safe and reliable and the like.
Description
technical field [0001] The invention relates to the field of tool manufacturing, in particular to a diamond cutter head production process based on vacuum cooling equipment. Background technique [0002] The diamond segment is the main body of the diamond saw blade, and the diamond segment and the substrate are welded together to form a diamond saw blade. Since the diamond cutter head is in direct contact with the cut material during the cutting process, the performance of the diamond cutter head has a decisive effect on the quality of the diamond saw blade. If you want to improve the performance of the diamond cutter head, you must first start with its production process. [0003] At present, the production process of diamond cutter head mainly includes four steps of mixing, pressing, sintering and cooling. Due to the good thermal conductivity of the graphite mold and the low deformation rate at high temperatures, the sintering and cooling processes of the diamond segment...
