Problems solved by technology
Solid chopsticks waste material and are bulky, which is inconvenient to use; hollow cylindrical chopsticks are easy to roll, and the hand feeling of clamping or holding and positioning is poor; in general, only hollow square-round chopsticks save material and are convenient to use
The traditional method of making metal hollow round-square chopsticks is to complete the chopsticks by cold forging, stretching or calendering. However, due to the constraints of materials and process conditions, the above method also has low production efficiency and poor surface quality of chopsticks. poor consistency

Embodiment Construction
[0018] The content of the present invention will be further described below with reference to the accompanying drawings and embodiments, but the practical application form of the present invention is not limited to the following embodiments.
[0019] Referring to the accompanying drawings, the metal hollow chopsticks forming equipment of the present invention mainly includes two parts: a mold 15 and a hydraulic system. The mold 15 in the equipment consists of an upper mold, a lower mold, a vertical guide post 7, a horizontal guide post 8, a fixed mold, a vertical mold 5 that can move up and down along the vertical guide post 7, and a horizontal mold that can move horizontally along the horizontal guide post 8. The mold is composed of 10 and other components, and 10 square-round chopstick-like structure cavities 15a are arranged in parallel along the horizontal direction in the mold. 110mm, diameter Ф=5~6mm, in the fixed die 4 and the horizontal die 10, there are conical surfac...

The invention relates to a forming process and a forming device of metal hollow chopsticks; the processing steps are as follows: placing a thin-wall metal round tube in a square-round chopsticks-like structure cavity, filling the metal round tube with pressure oil, causing the metal round tube to be deformed to be a square-round chopsticks-like structure tube by hydraulic pressure, then carrying out the procedures of welding seal head at two ends of the chopsticks-like structure tube to manufacture the metal hollow chopsticks; the forming device provided by the invention comprises moulds and a hydraulic system, wherein the moulds consist of an upper mould, a lower mould, a vertical guide pillar, a horizontal guide pillar, a vertical mould, a horizontal mould and the like, the moulds are internally provided with a plurality of square-round chopsticks-like structure cavities, and the hydraulic system consists of a hydraulic pump, a pilot overflow valve, a vertical hydraulic cylinder, a horizontal cylinder, a cone lubricating nipple and a plurality of solenoid directional valves. Compared with the prior art, the invention has the characteristics of excellent material utilization performance, high production efficiency, convenience for mass production and good consistency of the surface of the produced metal hollow chopsticks, light texture, comfortable handfeel and the like.
Description
technical field [0001] The content of the invention belongs to the technical field of tableware manufacturing, and relates to a forming process and equipment for metal hollow chopsticks. Background technique [0002] At present, the well-known types of metal chopsticks on the market mainly include solid cylindrical (including straight cylindrical and conical cylindrical) chopsticks, solid square-round chopsticks, solid flat square (commonly used in the Korean market), hollow cylindrical (including straight cylindrical) chopsticks type and cone-cylindrical type) chopsticks and hollow square-round chopsticks, etc. Solid chopsticks waste materials and are cumbersome and inconvenient to use; hollow cylindrical chopsticks are easy to roll and have poor grip or grip; in general, only hollow square-round chopsticks save materials and are easy to use. The traditional method of making metal hollow round-square chopsticks is to complete the chopsticks by cold forging, drawing or roll...
