Floating tube plate forge piece of heat exchanger

The utility model provides a heat exchanger floating tube plate forge piece which comprises a circular-plate-shaped body, and an annular groove is formed in one end face of the body and used for being connected with a floating head end cover. The other end face of the body is provided with a plurality of annular protrusions which are concentrically arranged at intervals and used for being connected with hook rings in a clamping mode. The floating tube plate is fixed through the protrusion clamping hook ring, the machining precision is low due to the arrangement of the protrusion, and therefore the machining difficulty is lowered; the groove is used for installing the O-shaped ring, the O-shaped ring is easier to deform, under the combined action of the sealing gasket, the sealing performance between the floating tube plate and the floating head end cover is improved, and even if the floating head moves, the sealing effect cannot be affected. 本实用新型提供一种换热器浮动管板锻件，包括圆板形本体，所述本体一端面设有环形凹槽，用于连接浮头端盖；所述本体另一端面设有多个间隔、同心布
