Processing method of sealing ring of spinning machine die head

Abstract

The invention discloses a machining method of a spinning machine mold head sealing ring. The machining method comprises the steps that firstly, an alloy straight shank twist drill is utilized for positioning; secondly, a cutter with the model being MGG 300-GR928 is utilized to conduct machining successively to form a front inclined face section and a rear inclined face section of the sealing ring;thirdly, a cutter with the reverse cutter specification of a PCD 16*16 90-degree external circle cutter is utilized to polish the front inclined face section, and thus the front inclined face sectionis smooth; fourthly, the alloy straight shank twist drill is utilized for drilling, and thus a hollow part is formed; fifthly, a cutter with the model being PCD TBMT 060102 is utilized to polish theinterior of the hollow part, and thus the inner wall of the hollow part is smooth; sixthly, a cutter with the model being PCD MGMN 200 is utilized to polish the rear inclined face section, and thus the rear inclined face section is smooth; and seventhly, after polishing is completed, the sealing ring is separated from a blank in a cut mode by the cutter with the model being PCD MGMN 200. Accordingto the machining method of the spinning machine mold head sealing ring, continuous machining forming of the spinning machine mold head sealing ring is achieved, and the production efficiency of the spinning machine mold head sealing ring is improved.

Description

technical field [0001] The invention belongs to the technical field of seal ring processing, and in particular relates to a processing method for a die head seal ring of a spinning machine. Background technique [0002] The spinning die head of the spinning machine often needs to be replaced. When the die head is installed on the spinning machine, it needs to be connected with a special sealing ring. The sealing ring includes a front inclined surface section, an equal diameter section, an umbrella The cover part, the rear inclined surface section, and the sealing ring have a hollow part. In order to ensure the sealing effect, the surfaces of the hollow part, the front inclined surface section, and the rear inclined surface section all need to be polished. Since both ends need to be processed, in the existing processing technology, only one end of the embryo body can be clamped, the other end is processed with a cutter, and then the embryo body is removed, and the processed ...
