Heat exchanger bottom plate casting punching and polishing device

Abstract

The invention provides a heat exchanger bottom plate casting punching and polishing device. The heat exchanger bottom plate casting punching and polishing device comprises a support structure; a fixing structure; a sliding structure; a rotating structure; and a driving structure. The rotating structure is arranged outside the sliding structure, the rotating structure comprises fixed seats, handles, axle seats, second rotating shafts, first grooves, gears, a grinding knife and a drill bit, the fixing seats are provided with the first grooves, the fixing seats are slidably connected to the outside of the sliding structure through the first grooves, the handles are fixed on one sides of the fixed seats, a third rotating shaft is rotatably connected with the bottom ends of the fixed seats, thegrinding knife is fixed on the bottom end of the third rotating shaft, the drill bit is fixed on the bottom end of the grinding knife, the two shaft seats are arranged, and the two shaft seats are fixed to the inside of the fixed seats.. The heat exchanger bottom plate casting punching and polishing device has the advantages of integrating punching and polishing, saving manufacturing time and improving working efficiency.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a device for punching holes and polishing a casting of a bottom plate of a heat exchanger. Background technique [0002] The heat exchanger is a device that transfers part of the heat of the hot fluid to the cold fluid. It is also called a heat exchanger. It is necessary to punch holes in the casting of the bottom plate of the heat exchanger, and the heat exchanger can be fixed and installed. [0003] However, at present, during the drilling process of the heat exchanger bottom plate casting, the heat exchanger bottom plate needs to be drilled first and then polished by a grinder, which greatly wastes manufacturing time and affects work efficiency. [0004] Therefore, it is necessary to provide a new heat exchanger bottom plate casting drilling and polishing device to solve the above technical problems. Contents of the invention [0005] The technical problem to be sol...
