The invention relates to a pipe expander, in particular to a middle reference structure device for the pipe expander of a gilled tube radiator. The invention is characterized in that two gear cases are middle reference parts fixed on a machine body; the upper ends of two long screws are fixedly connected with a floating plate and the lower ends are connected with a fixing faring beam after the twolong screws passes through a clapboard and a thrust beam to lead the floating plate and the faring beam to form a rigid framework through the connection of the two long screws; a faring screw rod passes through a discharge beam, the faring beam, a fine adjusting screw nut, a faring screw nut, a clapboard, a thrust beam, a floating plate and is connected with an upper otic placode at the upper endand the lower end passes through an upper plate of the gear cases and is fixed on a ratcheting; the upper end of the screw rod at the bottom part is connected with the ratcheting and the lower end passes through the bottom parts of the gear cases, a fastener and a cross beam for a receiving beam and is fixed on the machine body through a bearing seat; a gear system in the gear cases is in gear driving connection with the ratcheting and a limiting threaded sleeve; a top rod of shrinkage mass is connected with an air cylinder; a single chain wheel and a double-chain wheel are fixed on the lowerend of the screw rod at the bottom part and forms a chain wheel system with a small chain wheel on a retarding machine. The invention has the advantages of field operation, simple structure, low cost, convenient operation, flexible use, much work force saving as well as time, labor and work saving.
Description
(1) Technical field [0001] The invention relates to a tube expander, in particular to a central reference structure device of a tube-fin radiator tube expander. (2) Background technology [0002] At present, the tube expanders used in various countries in the world have to increase or decrease the number of fixtures due to changes in product specifications. Like this, fixture just has to be disassembled and assembled according to its needs. It is very troublesome to work. Due to the change of product specifications, the adjustment of the corresponding mechanism caused by the change of expansion and shrinkage is very cumbersome. Moreover, it is also easy to cause defective products. (3) Contents of the invention [0003] The purpose of the present invention is to provide a central reference structure device of tube-fin radiator tube expander which can be operated on site without dismantling, only for size adjustment, and fine-tuning of expansion and contraction. The pur...
