Spherical tube machine tool and machining method thereof

Abstract

The invention provides a refrigerator freshness preservation device and a method thereof. The device comprises a machine frame, a guide rail arranged on the machine frame, and a double-ended synchronization die in sliding connection with the guide rail. The guide rail is in sliding connection with a fixture and two forming blocks furthermore. The fixture is used for clamping a workpiece. The forming blocks are located at the two ends of the workpiece, and are used for carrying out machining to form the external shapes of the two ends of the workpiece. Forming grooves which are matched with thetwo ends, formed after machining, of the workpiece in shape are formed in the forming blocks. With the refrigerator freshness preservation device and the method thereof, the workpiece which is a hollow metal tube is machined into a spherical tube, a traditional machining mode is effectively broken, the machining efficiency and the machining accuracy of the spherical tube are effectively improved,the workpiece is detected and corrected during machining, the ends of the workpiece are thickened evenly, the workpiece is improved in structural strength, and the machining quality of the sphericaltube is effectively improved; and the refrigerator freshness preservation device and the method thereof can be used for machining a metal tube into an integrally formed metal bottle or an article withother structure, and therefore being broad in application.

Description

technical field [0001] The invention relates to the field of workpiece processing, in particular to a spherical tube processing machine tool and a processing method thereof. Background technique [0002] Spherical tubes are widely used and can be used in pressure vessels, mines, construction and other fields. The patent No. CN106440957A discloses a disposable spherical polyester gas blaster and its manufacturing method. The disposable spherical polyester gas blaster The blaster includes an energy storage device and an inflatable detonation device. The detonator is installed at one end of the energy storage device, and the other end is sealed or integrally formed. The energy storage device is made of solidified polyester material, and the energy storage device is spherical. But the spherical tube is relatively difficult in the process of processing, especially the material of the spherical polyester gas blaster is made of metal material, and it is difficult to meet the proces...

Problems solved by technology

It includes a driving mechanism, a forming device, a hydraulic control system and an electrical control system; the driving mechanism includes a first hydraulic cylinder; The control system includes an electrically connected controller and a first displacement detection device; the first hydraulic cylinder can drive the movable mold close to or away from the fixed mold; the hydraulic station communicates with the first hydraulic cylinder through a pipeline, and the control valve group is arranged in the pipeline; The device is electrically connected with the control valve group, and the first displacement detection device is set on one side of the molding device and can detect the molding displacement of the movable mold and the fixed mold during extrusion molding; but the equipment cannot be used to process it into hollow metal ball

[0006] The processing equipment and method using metal balls in the above patents cannot meet the requirements of processing the two ends of the pipe fittings into spherical or elliptical shapes, and the traditional method of processing cannot meet the requirements for the use of workpieces. Flying heads are prone to occur during the process, and the pressure bearing capacity and sealing effect are poor, which seriously affects the safety of use
