Bending device for heating pipe of evaporator

Abstract

The invention discloses a bending device for a heating pipe of an evaporator. The bending device comprises a workbench, an upper mold plate, a lower mold plate, pipe bending wheels and a power cylinder. The workbench is of a frame structure, a horizontally-arranged supporting plate is arranged on the lower middle portion of the workbench, and the upper portion of the workbench is fixedly connected with the horizontally-arranged upper mold plate. The lower mold plate is arranged below the upper mold plate, and the upper end face of the lower mold plate is fixedly connected with the multiple vertical columnar pipe bending wheels. Upper and lower through holes with the positions corresponding to the positions of the pipe bending wheels are formed in the upper mold plate so that the pipe bending wheels can pass. The power cylinder is arranged vertically and arranged between the lower end face of the lower mold plate and the upper end face of the supporting plate, and the end of a piston rod of the power cylinder is fixedly connected with the lower end face of the lower mold plate. According to the further improvement, the pipe bending wheels are in clearance fit with the through holes of the upper mold plate; and an air cylinder serves as the power cylinder. The bending device is simple in structure and convenient and fast to operate, and production efficiency is effectively improved.

Description

technical field [0001] The invention relates to a pipe bending tool, in particular to a heating pipe bending quick demoulding device. Background technique [0002] Refrigerator evaporators are mostly bent from metal tubes. The prior art uses manual tube bending tooling for bending. The existing manual tube bending tooling cannot take out the workpiece in time after the metal tube is bent, so the work efficiency is low. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes an evaporator heating tube bending device with simple structure, quick operation, low cost and significantly improved production efficiency. [0004] The present invention achieves technical goals through the following technical solutions. [0005] The evaporator heating tube bending device is improved in that it includes a workbench, an upper template, a lower template, a pipe bending wheel, and a power cylinder; Connect the horizontal upper form...
