Example Embodiment

[0029] Implementation mode two:

[0030] Such as figure 1 As shown, on the basis of the first embodiment, the thread teeth on the first threaded mandrel 2 and the second threaded mandrel 5 have the same diameter and the same direction, so that the size of the threads formed when the cemented carbide powder 4 is pressed can be the same, and The thread direction is also the same thread.

Example Embodiment

[0031] Implementation mode three:

[0032] Such as figure 2 As shown, the thread teeth on the first threaded mandrel 2 and the second threaded mandrel 5 have the same diameter and different directions, so that when the cemented carbide powder is pressed 4, threads with the same thread size and different thread directions can be formed.

Abstract

The invention discloses a device and method for pressing threads at the two ends of a hard alloy cylinder simultaneously. The device is characterized in that a first plug, a first threaded core shaft,a second plug, a second threaded core shaft and a die sleeve are included; in the using state, the first plug, the first threaded core shaft, the second plug and the second threaded core shaft are all coaxial with the die sleeve; the first plug and the second plug are located at the two ends of the die sleeve correspondingly and fix the first threaded core shaft and the second threaded core shaftcorrespondingly; the first threaded core shaft and the second threaded core shaft are connected in the axis direction; and threaded teeth are arranged on the first threaded core shaft and the secondthreaded core shaft. Hard alloy powder is pressed into the threads, operation is easy, and the machining precision and efficiency are high; and by changing the diameter and direction of the threaded teeth on the two threaded core shafts, the threads with different needs can be obtained at the two ends of the hard alloy cylinder simultaneously, the machining efficiency is greatly improved, and meanwhile the matching degree of the hard alloy cylinder to various different threaded connectors is met.

Description

technical field [0001] The invention belongs to the field of cemented carbide thread processing, and in particular relates to a device and method for simultaneously pressing threads at both ends of a cemented carbide cylinder. Background technique [0002] At present, the internal thread of the cemented carbide cylinder is usually processed by cutting, which has low work efficiency and low processing accuracy. When the cemented carbide cylinder is in use, its two ends are usually connected to different types of components. Different components have different requirements for the structure and size of the internal thread at both ends of the cemented carbide cylinder. Separate cutting is usually used when processing, and its processing efficiency is low and the precision is not high. Contents of the invention [0003] The present invention aims at the problems of low processing accuracy and processing efficiency of existing cemented carbide cylinder threads, and it is diffi...
