Machining device and machining method of metal foils

Abstract

The invention relates to a machining device and a machining method of metal foils. The machining device mainly comprises a handle, a supporting frame, a cutter head, a material pressing plate, a supporting plate, a main frame, a base plate, a workpiece, a support, head pressing springs, a supporting rod, an inner pressing head, a locking handle, a sliding block, a groove, a pressing rod, a handle support and the like. The handle, the supporting rod, the locking handle and the handle support are all installed on the supporting plate, the springs are sleeved on the supporting rod and the inner pressing head respectively, the cutter head is in threaded connection with the supporting rod, the inner pressing head is installed in the center of the supporting rod, the material pressing plate and a bottom die are connected and then installed on the base plate, the sliding block is installed in the groove of the main frame, the main frame is installed on the base plate, and the pressing rod is installed on the handle. The machining method conducts machining and cutting on the metal foils by the adoption of the mechanical force application mode, the machining device and the machining method are high in work efficiency, the speed and precision are high, cutting on the metal foils with the different sizes can be achieved, and the machining device and the machining method are suitable for cutting the metal foils of various specifications.

Description

technical field [0001] The invention relates to a metal foil processing device and method, in particular to a metal foil processing device and a processing method for a nuclear power plant pressurized water reactor pressure vessel detection sheet, belonging to the field of nuclear industry mechanical processing. Background technique [0002] According to the regulations, the fast neutron fluence exposure to the reactor pressure vessel must be monitored during the operation of the nuclear power plant, and the in-reactor irradiation supervisory tube is usually used to achieve this purpose. The external neutron dosimeter installed outside the reactor pressure vessel can be used as an effective supplement for in-reactor radiation supervision. [0003] The external neutron dosimeter selects some specific pure metal foils, places them in the neutron environment of the reactor cavity for activation, measures the activity of the activated products after taking them out, and then cal...
