Core assembling machine for evaporator

Abstract

The invention discloses a core assembling machine for an evaporator. The core assembling machine comprises a machine body, a working platform and a hydraulic cylinder; the working platform is mounted on the machine body; the hydraulic cylinder is mounted on the working platform; and a positioning board is further arranged on the working platform. The core assembling machine is characterized in that a pressing board corresponding to the positioning board is connected with a push rod of the hydraulic cylinder through a pressure sensor; the pressure sensor is connected with a programmable controller; a hydraulic cylinder is provided with two hydraulic oil paths; a first solenoid valve is arranged on one oil path, and a second solenoid valve is arranged on the other oil path; and the first solenoid valve and the second solenoid valve are connected with the programmable controller. With the adoption of the structure provided by the invention, when core assembly is carried out on the evaporator, a core is automatically pressed under a set pressure condition, so that the evaporator changes pressure variation set depending on experience to quantization set in a core assembling process. Therefore, the evaporator with the pressed and assembled core is uniform. Furthermore, the operation is convenient.

Description

Technical field [0001] The invention relates to a device for combining evaporator cores. Background technique [0002] The evaporator is an indispensable part of refrigeration equipment. When it is manufactured, it is an important process to assemble and press the core. The currently used equipment for assembling the evaporator core also includes a body 1'and a working platform 7'. A hydraulic cylinder 6'is provided on the working platform 7', and the push rods of the hydraulic cylinder 6'extend out of both ends of the cylinder body. A fixed plate 3'is provided on the working platform 7', one end of the hydraulic rod 6'push rod 10' is provided with a pressing plate 5'corresponding to the fixed plate 3', and the other end is provided with a thread and a nut 9'is screwed. , There is a nut limit block 8'on the cylinder body, the hydraulic cylinder is connected with an oil circuit, and an oil valve is arranged on the oil circuit. When working, the core assembly is placed on the wor...

AI Technical Summary

Problems solved by technology

Since the core body is pressed by the pressure plate, it is necessary to use a clamp to clamp the pressed core body before the pressure plate leaves, so as not to fall apart, and due to the limited width of the workbench, after installing the cylinder and push plate on it, The lateral position of the table is small, so when clamping the core with a jig, it is very inconvenient to operate due to limited space
