Problems solved by technology
[0005] For the above-mentioned dovetail forgings, after forging and forming, the difficulty in achieving the machining accuracy of the forgings by machining is that during the processing, if the dovetail forgings are subjected to an axial Y clamping force (that is, the axial end surface is clamped holding), when the peripheral surface of the head 3 is processed first and then the peripheral surface of the dovetail body 2 is processed, the fixture will be disassembled, and the dovetail forging will be clamped again before processing, which will cause inconsistent clamping accuracy and easily reduce the dovetail forging machining accuracy

Embodiment Construction
[0043] Such as figure 2 , the manufacture method of dovetail forging of the present invention, comprises the following steps:
[0044] S1, sending the forging blank A into the heating device C for heating, using an intermediate frequency furnace for heating, for example, heating the cylindrical forging blank A to 1175°C in the intermediate frequency furnace.
[0045] S2. After the heated forging blank A is screened by temperature, the qualified forging blank A is sent to the forging equipment to be forged into a semi-finished dovetail forging B. As qualified, below 1150°C or above 1200°C will be regarded as unqualified forging blank A, and only qualified forging blank A can be used for forging.
[0046] S3, placing the semi-finished dovetail forging B after cooling (for example, natural cooling) in a resistance furnace for heat treatment. In this embodiment, the heat treatment adopts a conventional process.
[0047] S4, cut test samples from the semi-finished dovetail forg...

The invention relates to a manufacturing method of a dovetail forging, comprising the following steps: S1, sending the forging blank into a heating device for heating; S2, after the heated forging blank is screened by temperature, sending the qualified forging blank into the Forging semi-finished dovetail forgings in the forging equipment; S3, placing the cooled semi-finished dovetail forgings in a resistance furnace for heat treatment; S4, cutting test samples from the heat-treated semi-finished dovetail forgings, and processing them into tensile test pieces samples and impact samples, and carry out mechanical performance tests; S5, the semi-finished dovetail forgings in step S4 are processed into qualified dovetail forgings by machining. For cutting. The invention has the advantage of ensuring the processing accuracy of the dovetail forging.
Description
technical field [0001] The invention relates to the technical field of forging, in particular to a method for manufacturing a dovetail forging. Background technique [0002] Forging is a processing method that uses forging machinery to apply pressure to metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. It is one of the two major components of forging (forging and stamping). Forging can eliminate defects such as as-cast porosity produced in the metal smelting process and optimize the microstructure. At the same time, due to the preservation of complete metal flow lines, the mechanical properties of forgings are generally better than castings of the same material. [0003] CN108359902A discloses a manufacturing method of a high-performance alloy steel flange and a forging, which includes forging an alloy steel ingot with a hydraulic press or an air hammer into a product forging; placing the naturally cool...
