Combined ear for kitchenware and its production process

Abstract

The present invention discloses one kind of combined ear for kitchenware and its production process, and solves the technological problem of ensuring the accurate locating and connecting between the heat- isolating piece and the ear body. The metal ear body is once polished and this results in shortened technological process and raised production efficiency. The metal ear body is provided with hard non-metal connecting piece and double-layered composite non-metal heat isolating piece with hard inner layer and soft outer layer. The present invention is used mainly for kitchenware and may be also for other application.

Description

technical field [0001] The invention relates to the technical field of cooker accessories, in particular to a combined cooker ear and a production method thereof. Background technique [0002] An existing cooking utensil ear is composed of a metal ear body and a non-metal safety heat insulating part. The safety heat insulating part is arranged under the metal ear body, and a metal sheet is arranged inside. Metal pins are welded at both ends of the sheet, and then rubber Or soft plastic pouring is combined to form a safety heat insulator, and the middle section of the metal ear body is provided with two through holes matching the above-mentioned metal pins. The manufacturing method of this cooking utensil ear is as follows: (1) the metal ear body is polished and shaped; (2) the non-metallic safety heat insulating part is placed under the middle section of the metal ear body, and the two metal pins are connected with the metal ear body. The two small through holes of the meta...

Problems solved by technology

[0003] (1) Since the non-metal safety heat insulation parts are made of soft rubber and plastic materials except for a metal sheet hidden in the inner core, there are large errors in the position accuracy of the metal sheet and pins in the composite, and the metal ear body There is also a certain gap between the small through hole and the pin, which makes it difficult to ensure the exact position of the safety and heat insulation parts in the metal ear body, thus affecting the product quality

[0004] (2) During the welding process, the welding temperature is high, which often causes the safety heat insulator to be discolored or damaged due to high temperature; at the same time, due to the high temperature generated by welding, the metal ear body will also be deformed, resulting in separation from the safety heat insulator. At that time, it was difficult to shape the metal ear body, so it had to be scrapped, resulting in a high rate of scrap and defective products

[0005] (3) Due to the secondary grinding and polishing of the metal ear body, the process flow is complicated and the production efficiency is low; in the second polishing process, the metal ear body is often deformed again due to heat, making it different from the safety insulation body The bonding effect of the safety insulation body will become poor, and it will also cause the surface of the safety insulation body to become dirty and discolored, and it will be scrapped due to cleaning difficulties
