Problems solved by technology

The screw is the core component of the household juicer. The feeding, pressing of ingredients and discharge of filter residues of the household juicer are all done by the screw. When it rotates and squeezes the ingredients, on the one hand, its working surface will receive the ingredients. On the other hand, the thread formed on it will be squeezed by the ingredients, so the household juicer screw made of plastic often fails due to surface wear or thread breakage during use, so that the household juicer Completely or partially lose the ability to extract juice and be scrapped, reducing the service life of the juice extractor

Embodiment 1

[0042] like figure 1 , figure 2 As shown, a household juice extractor screw includes an upper central shaft 1, an arc-shaped conical screw body 2, a screw thread 3 formed on the screw body 2, and a lower central shaft 4. The lower end of the lower central shaft 4 is provided with There is a shaft hole 5, which can be inserted into the transmission output shaft of the motor. When the motor rotates, the screw will also rotate; Avoid the shaking phenomenon of the household juicer screw caused by the different shafts of the upper and lower central axes when the screw of the household juice extractor rotates; the screw thread 3 formed on the screw body 2 has multiple threads, that is, multiple threads, and the number of threads of each thread The starting positions are different, but all terminate at the lower end of the screw body 2 .

[0043] The screw rod of this embodiment is completely made of acid and alkali-resistant food-grade stainless steel 304, so when using it to...

Embodiment 2

[0053] The manufacturing method of the above-mentioned domestic juice extractor screw also includes the following steps:

[0054] Step 1: Pouring the screw parts of the household juice extractor with metal materials: left part 6, right part 7 and lower part 8;

[0055] Step 2: Process and remove the burrs and sundries on the assembly surface of the screw parts;

[0056] Step 3: Assembling, bonding or riveting the screw parts into a rough screw;

[0057] Step 4: cutting and processing the relevant surface of the screw rough blank;

[0058] Step 5: Grinding the relevant surface of the screw rod after cutting, which is the finished screw rod of the household juice extractor.

Abstract

The invention provides a household juicer screw and a manufacturing method thereof. The household juicer screw is completely made of metal. The manufacturing method includes casting screw parts by the metal, assembling the screw parts into a blank screw, eliminating residual welding stress in the blank screw by thermal treatment or aging treatment, cutting the blank screw until the blank screw conforms to the size requirement, finally polishing the operating surface and the welding seam of the screw to complete manufacture of the household juicer screw. The manufacturing method of the household juicer screw is simple, and the household juicer screw is long in service life and can replace widely used plastic screws in household juicers of the prior art.

Description

technical field [0001] The invention relates to the field of household juice extractors, in particular to a household juice extractor screw and a manufacturing method thereof. Background technique [0002] Existing household juice extractor screw rod is all formed by plastic injection molding, and only central axis is a metal insert, and its cambered tapered body and the screw threads that are formed on the body and play the role of feeding and squeezing are all plastic. The screw is the core component of the household juicer. The feeding, pressing of ingredients and discharge of filter residues of the household juicer are all done by the screw. When it rotates and squeezes the ingredients, on the one hand, its working surface will be affected by the ingredients. On the other hand, the thread formed on it will be squeezed by the ingredients, so the household juicer screw made of plastic often fails due to surface wear or thread breakage during use, which makes the household ...
