Composite punching equipment of inner lining of refrigerator

Abstract

The invention provides composite punching equipment of an inner lining of a refrigerator. The equipment comprises a pedestal, wherein the pedestal is symmetrically provided with two width adjustment platforms; a back punching component and a top lamp punching component are arranged between the two width adjustment platforms in sequence; the upper parts of the two width adjustment platforms are provided with side edge air hole punching mechanisms respectively; the two side edge air hole punching mechanisms are symmetrically arranged; a lamp switch punching component is arranged on one side of the side edge air hole punching mechanism on one platform, and a right punching component is arranged on the other side; original holes are punched in the way that each hole is punched by one punching equipment; the investment cost of the equipment is high, the production energy consumption is high, and the equipment is adverse to the environmental protection; all holes are punched at one time, so the production processes are reduced, the investment of the equipment is reduced, the production energy consumption of enterprises is reduced, the production efficiency of the enterprises is improved, and the production cost of the enterprises is reduced.

Description

technical field [0001] The invention relates to the field of refrigerator production equipment, in particular to composite punching equipment for refrigerator liners. Background technique [0002] At present, the total production of domestic refrigerators in my country has reached more than 100 million units. The inner tank of the refrigerator is an important component of the refrigerator. The inner tank is usually equipped with a fresh-keeping light hole on the back, a temperature-sensing probe hole on one side, and a light switch hole. The led light hole on the top of the inner tank. [0003] In the process of production, there is a process of injecting foaming agent between the inner tank of the refrigerator and the outer shell of the refrigerator, in order to prevent bubbles from being generated when the foaming agent is injected, resulting in false filling. Therefore, before injecting the foaming agent, it is necessary to poke appropriate ventilation holes on both sides...

AI Technical Summary

Problems solved by technology

At present, manual methods are commonly used in China to poke various holes in the inner tank. If one inner tank needs to poke 60 air holes, it takes a skilled operator 120 to 150 seconds to complete one inner tank.

[0004] At present, when our country punches all the holes on the refrigerator liner, it adopts the method of punching holes one by one, which requires multiple processes. Each hole needs a punching equipment, and some holes need to be done manually. Punching, which increases the production cost of the enterprise, increases energy consumption, and thus greatly reduces the work efficiency of the enterprise
