Embodiment 1

[0032] A manufacturing process for the upper cover of a 105 double-head assembly with a length of 29mm and an outer diameter of Φ104mm, comprising the following steps:

[0033] Step a, sawing machine blanking: Φ110×34mm bar;

[0034] Step b, roughing the outer diameter and each step, use the outer circle rough turning tool to rough turn one end of the outer circle to Φ106.5mm, and rough turn the other end of the step to Φ77mm, the length is 13mm, leave a margin of 1mm, and chamfer 1×45° , surface roughness Ra≤12.5;

[0035] Step c, quenching and tempering the semi-finished product, the quenching temperature is 850-900°C, the tempering temperature is 550-650°C, and the hardness of the parts is controlled within the range of HRC30±2.5;

[0036] Step d, finish turning outer diameter and steps, use outer circle finishing tool to light out Φ106.5mm end face 1mm, Ra≤1.6, finish turning outer circle Φ106.5mm to Φ104.50 -0.05mm, Ra≤3.2, outer circle and The verticality of the end fa...

Abstract

The invention discloses a manufacturing process for top covers in double-headed components of spinning manifolds, which includes the following steps: blanking on a sawing machine, rough turning of an external diameter and steps, hardening and tempering of a semifinished product, finish turning of the external diameter and the steps, drilling of pin holes and threaded holes, milling of a semicircular cavity, tapping of a central hole, flat grinding of the end surface of the cavity, machining of eccentric holes and circular arc-shaped holes, turning of the taper of the eccentric holes, polishing and driving of pins. The production efficiency of the manufacturing process for top covers is high, the production quality is stable, the precision is high, and the quality of products is good.

Description

technical field [0001] The invention relates to a manufacturing process for an upper cover used in a double-head assembly of a spinning box body. Background technique [0002] The spinning box is composed of a melt distribution pipe, a metering pump, and a spinning assembly. The melt filtered by the filter enters the spinning box. The spinning box is a rectangular heat carrier heating box, which is equipped with melt distribution pipes, metering pumps and components, and is covered with heat insulating materials to keep the melt warm. At present, the manufacturing process for the upper cover in the double-head assembly of the spinning box can not be industrialized, the production efficiency is low, and the production quality is not stable enough. Contents of the invention [0003] In view of the above technical problems, the present invention discloses a manufacturing process for the upper cover in the double-head assembly of the spinning box, which includes the following...
