Patent name: Manufacturing method of automatic foot bending machine

Technical field:

The utility model relates to an assembly machine for eyeglasses, in particular to a device for bending eyeglass feet.

In addition to the traditional copper alloy and titanium metal, there are super elastic metal materials such as white iron (stainless steel) and memory alloy. In the processing procedure of the metal spectacle foot bending foot, the traditional method is by hand (that is, human hand) ) To bend, so it is not only time-consuming and labor-intensive, but also has different angle quality; and in the current manufacturing industry, machinery is used to replace manual methods to obtain rapid and standardized requirements for uniform bending foot quality; but with the current The design of the automatic foot bending machine for eyeglass feet developed on the market is to set a mold on a platform for the frame and feet to be processed, and then use the up and down displacement stamping rollers to press and bend the placed on the mold. Spectacles, this machine design uses the preset angle of the mold to attach and bend the pressed temples to achieve the automatic processing of bending the temples. However, in practical applications, this machine has the following Limitations and shortcomings (1) The fixed mold and the corners on the mold are designed to provide bending processing for the temples under pressure. For the temples that are bent, the corners are only affected by The mold has a little support, so the corners of the spectacles manufactured and processed are not smooth, so the glasses are susceptible to discomfort when worn.

(2) The angle of the temple is stamped and rolled with a fixed mold on the platform. Basically, the angle between the upper and lower displacement rollers and the bending point of the mold is at most 90 degrees, so the maximum bending angle is only And 90 degrees. For the temples made of super-elastic metal materials, the recovery ability of the rebound rebound under pressure is generally 90-degree rolling bending processing, and it cannot make the super-elastic metal temples bent at one time. It fits the required angle of wearing, so the general machine can only be applied to metal temples with low elasticity, and can not be used for processing of super elastic metal temples, because the processing bending angle will restore part of the angle due to the elasticity of the material, so that the angle is too Large, it must be adjusted by manual bending, which is extremely inconvenient in processing procedures and is not applicable.

(3) The angles, curvatures, etc. required by various eyeglass bending machines for various types of eyeglasses cannot be ideally adjusted, so the processing quality is less likely to meet the exact requirements.
