Abstract
The invention relates to the technical field of thermal treatment, and provides a lead screw shaping device for practical production, which includes a lead screw sleeve 1, lead screws 2, steel balls 3 and cushion blocks 4, wherein the lead screw sleeve 1, the lead screws 2, the steel balls 3 and the cushion blocks 4 are sequentially connected. The lead screw shaping device includes the lead screw sleeve 1, the two lead screws 2, the two steel balls 3 and the two cushion blocks 4. The lead screw sleeve 1 is in threaded connection with the lead screws 2. The lead screw shaping device is made of 1113 hot work die steel. A thermal correction method for elliptic deformation of a ring product includes the steps of preheating, shaping and thermal setting. After a gear ring is subjected to the thermal setting treatment, the measured deformation of the gear ring is within 1mm. Products achieving required deformation are qualified products.
Description
Technical field
The present invention relates to the heat treatment process technical field, particularly the thermal recalibration method of leading screw apparatus for shaping and circle series products ovalizing deflection.
Background technology
Factory needs the modified back of heat treated circle class workpiece (as Fig. 1, gear ring shaping procedure chart) ovality to be deformed into 16mm.The gear ring material is 42CrMo, substance 1500kg, and deflection requires less than 8mm.
Summary of the invention
For improving the quality of production, a kind of leading screw apparatus for shaping is provided in the actual production, comprise screw set 1, leading screw 2, steel ball 3 and cushion block 4, described screw set 1, leading screw 2, steel ball 3 and cushion block 4 are connected successively.
The leading screw apparatus for shaping comprises a screw set 1, connects a leading screw 2, two steel balls 3 and two cushion blocks 4.
Described screw set 1 and leading screw 2 are by being threaded.
The raw material of described device are that 11 13 hot die steels are made.
The thermal recalibration method of circle series products ovalizing deflection, comprise after the preheating shaping again thermal finalization handle concrete steps:
The first step: at first before preheating, find the summit, and carry out mark; Vertically carry out mark at the ovality end face less than 16mm radially;
Second step: then gear ring is gone into stove and be heated to 580～590 ℃;
The 3rd step: gear ring is saturating post-equalization diameter ring gear distortion all, remembers that with leading screw apparatus for shaping top mark ovality is less than the 16mm inner radius; Keep the leading screw apparatus for shaping;
The 4th step: gear ring is carried out thermal finalization handles, the related leading screw apparatus for shaping of gear ring go into together stove be heated to 580～590 ℃ all saturating back insulation greater than 8 hours,
The workpiece deformation amount is being controlled within 1mm.Reach the deflection of specification requirement, product is certified products.
The top is to measuring the big 1-2mm of radial dimension in the described step 3.
