Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] refer to figure 1 and figure 2 , the structure of the finished product of the processing object semicircle insert of the present invention is that a semicircular insert workpiece 1 is provided with a less semi-cylindrical surface 2 with a radius of R, the radius R of the less semicylindrical surface 2, and the lower plane where the center of the radius R is located The vertical distance H1 of 3 has relatively strict size requirements, and its tolerance requirements are usually within 0.08mm; the width of semicircular insert workpiece 1 is A1 (see figure 1 ), the length is B1 (see figure 2 ), there are two screw holes 4 on both ends of the length of the semicircular insert workpiece 1, the distance between the two screw holes 4 on each end face is C1, and the distance between the axis center line of each screw hole 4 and the lower p...

Abstract

The invention discloses a machining method for semicircular inserts. The machining method comprises the steps that 1, the parts, except the less half cylindrical surfaces, of semicircular insert workpieces are machined to the needed amount; 2, the two semicircular insert workpieces treated in the step 1 are installed in two installing grooves of a mandrel body, a jacking bolt is screwed into each jackscrew hole, the jacking bolts at the two ends are pre-tightened, and the two semicircular insert workpieces are installed on the mandrel body simultaneously every time; 3, the mandrel body on which the two semicircular insert workpieces are installed is clamped on a common lathe, turning is conducted on the less half cylindrical surfaces after aligning is conducted, and the moderate margin is reserved; and 4, the mandrel body and the two semicircular insert workpieces are clamped on a common cylindrical grinding machine, the less half cylindrical surface is ground to the size required by the workpieces, and then the semicircular inserts are obtained. According to the machining method, adopted tools and lathe equipment are simple, the machining cost is low, the working efficiency is high, and the finished product rate is obviously increased.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and relates to a method for processing a semicircular insert. Background technique [0002] In the production of aluminum profiles, it is often necessary to stretch and straighten the aluminum profile with a hydraulic stretch straightening machine to eliminate the bending and twisting of the aluminum profile. At present, the commonly used structure of the hydraulic stretch straightening machine at home and abroad is a frame structure, such as in the patent 200510042768.6 According to the above-mentioned structure, the hydraulic tension straightening machine of this structure needs to move the trolley to a suitable position on the frame, and the oil cylinder drives the pin to be positioned and fixed on a pair of holes in the frame, and then starts the stretching action, from It can be seen from the structure that the pin and the positioning hole need to bear the tensile force, whi...
