Problems solved by technology

[0002] The parts are similar to "wine glass" type die forgings, with irregular outer contours and uneven pressing points. Every time the parts are processed, they will be slightly displaced due to the pressing. It is difficult to control the displacement artificially, and the symmetry requirements of the parts cannot be guaranteed. Every time, a fitter is required to repair the symmetry, and sometimes the parts are scrapped due to excessive tolerance

Embodiment 1

[0044] Such as Figure 1-6 As shown, through the pre-processing position of the part, a smooth pressing plane is manufactured, the tooling is designed to cooperate with the pressing position, the processing sequence and the cutting route are changed, and the part is fully aged before finishing.

[0045] 1. Design the main fixture, use the inner precision hole of the part to make a set of self-made tooling connecting the machine tool and the part to ensure the verticality and stability of the part during processing. Since the inner hole of the part is used for positioning to prevent the parts from being scratched, the positioning part of the tooling is made of aluminum alloy.

[0046] 2. Design the internal thread connection hole M8 of the main body fixture. Because it is an internal thread connection hole, the loading and unloading parts must be used frequently, so the wear resistance of the material is very important. However, the material of the main body fixture is aluminum...

Embodiment 2

[0053] Such as Figure 1-6 Shown:

[0054] 1. Install the main fixture, align and press it on the turntable of the machine tool, and install the parts on the main fixture.

[0055] 2. Use the "A" type pressure plate to compress, and press it on the "neck" blank outside the part, and finish machining from below the pressure plate to the plane of the fixture, and perform rough machining allowance of 0.5mm otherwise. Removal of parts after machining.

[0056] 3. Use the positioning shaft to connect the part reference hole and the main body fixture to the positioning hole for angular positioning.

[0057] 4. Some characteristics of the part after rough machining will be revealed. The part has an inner hole of φ8.5 and a plane inside the fork, and the M8 screw rod and the M8 internal thread connection hole of the previous main body fixture pass through the part φ8. The inner holes of 5 are connected. The processed plane is used as the pressing plane to replace the "A" type pres...

Abstract

The invention belongs to processing technology, and relates to a processing device and method for processing wine glass-shaped die forgings. A processing device for processing wine glass-shaped die forgings, comprising: a main body fixture and an "A"-shaped pressing plate (6); the bottom of the main body fixture is a disc, and the disc is a three-stage stepped shaft, and the upper surface of the disc is provided with A pin hole; the lower part of the "A" type pressure plate (6) is a support rod, and the head is a horizontal "A" type, and a hole is arranged in the middle of the head of the "A" type pressure plate (6); On the stepped shaft, the supporting rod of the "A" type pressure plate (6) is pressed against the main fixture disc, the head of the "A" type pressure plate (6) is pressed against the neck of the part, and a bolt passes through the "A" type pressure plate (6) The middle hole of the head is inserted into the pin hole on the upper surface of the disc, and the bolt is tightened with a nut on the upper part of the "A" type pressure plate (6) hole.

Description

technical field [0001] The invention belongs to processing technology, and relates to a processing device and method for processing wine glass-shaped die forgings. Background technique [0002] The parts are similar to "wine glass" type die forgings, with irregular outer contours and uneven pressing points. Every time the parts are processed, they will be slightly displaced due to the pressing. It is difficult to control the displacement artificially, and the symmetry requirements of the parts cannot be guaranteed. Every time, a fitter is required to repair the symmetry, and sometimes the parts are scrapped due to excessive tolerance. Contents of the invention [0003] The object of the present invention is to propose a processing device and method for processing wine glass-shaped die forgings, which can control quality stability, reduce out-of-tolerance, and prevent scrapping. [0004] The technical solution of the present invention: a processing device for processing wi...
