Problems solved by technology

However, in the existing centrifugal casting equipment, when the liquid copper alloy is poured into the mold, part of it has been cooled and formed into blocks, which makes the density of the formed copper sleeve uneven, and is prone to deformation or cracks due to stress concentration during use.
Moreover, only a single copper sleeve can be cast at a time, and the production efficiency is low, which is not conducive to mass production. Therefore, it is necessary to design a new type of casting equipment

Abstract

The invention discloses a copper sleeve centrifugal casting device in the copper sleeve production field; and the copper sleeve centrifugal casting device comprises a frame, a motor, a cylinder, casting molds and a mold cover. A support column is fixed on the frame; a cantilever is fixed at the top end of the support column; and the cylinder is fixed at a free end of the cantilever. The mold cover is fixed at an output end of the cylinder; and multiple resistance rings are arranged on the mold cover. A driving shaft is inserted in the middle part of the frame; multiple transmission shafts are uniformly and annularly distributed around the driving shaft; and gears are respectively arranged on the driving shaft and the transmission shafts. Multiple casting molds are provided, and are respectively fixed at the top ends of the driving shaft and the transmission shafts; and the resistance rings are corresponding to the casting molds one to one. The casting molds are double-layer structures provided with heating cavities. The motor is fixed below the frame; and the output end of the motor is connected with the driving shaft. A molded copper sleeve is excellent in feeding conditions, compact in structure and uniform in density, generates no deformation or cracks due to stress concentration in use, and is better in quality; and the centrifugal casting molding of multiple copper sleeves can be synchronously finished, so that the production efficiency of the copper sleeves is greatly improved.

Description

technical field [0001] The invention relates to the field of copper sleeve production, in particular to a copper sleeve centrifugal casting device. Background technique [0002] Copper sleeve is a very broad name. Copper sleeve is a component used in sliding and rotating machinery to reduce friction while transmitting thrust and supporting and fixing. Copper sleeves, also known as "copper bearings", are made of various copper alloys for lubrication of mechanical parts. They are used in various large and heavy machinery and are important components of machinery. The materials commonly used for copper sleeves include ZCuSn10Pb1, ZCuSn10Pb5, ZCuPb10Sn10, ZCuPb15Sn8, ZCuZn38Mn2Pb2, etc. Copper sleeves are generally manufactured by metal mold casting, centrifugal casting, sand casting, etc. Among them, centrifugal casting is a casting method in which liquid copper alloy is poured into a rotating mold, filled and solidified into a copper sleeve under the action of centrifugal fo...
