Example Embodiment

[0015] Embodiment one:

[0016] refer to figure 1 , a production process for spinning handrails, which mainly includes the following steps: first, the metal worker chooses Q235 ordinary steel pipe as the base structure, and cuts the material according to the length given on the drawing (the equipment used is a sawing machine)——after the pipe is sawed Metalworking for pipe bending (a total of two bends, the equipment used is a pipe bender) - after two bends are bent, punching and forming (punching machine) - punching as required (punching machine) - grinding the surface of the handrail tube De-stabbing treatment;——Weld the handrail pipe 1, the handrail fixing piece 2, and the handle pipe plug 3 with the pre-made fixtures to form a semi-finished handrail (the fixture must be clamped in place, and all pressing hands must use upper clamps Tight)——Welding and correcting the semi-finished handrails to avoid uneven height of the handrails;——Degreasing (using alkaline degreasing powd...

Example Embodiment

[0017] Embodiment two:

[0018] The pre-baking temperature is 320° C., and the time is 20 minutes. The curing temperature is 180° C., and the time is 14 minutes. Others are the same as in Example 1.

Example Embodiment

[0019] Embodiment three:

[0020] The pre-baking temperature is 370° C., and the time is 14 minutes. The curing temperature is 200° C., and the time is 6 minutes. Others are the same as in Example 1.

Abstract

The invention relates to a production process of a spinning handrail, mainly comprising the following steps of: firstly, preparing a handrail tube; secondly, welding the handrail tube with other accessories; thirdly, degreasing, washing, pickling, washing, surface conditioning, phosphating, washing and drying; fourthly, cleaning, spraying, solidifying and workpiece unloading; and fifthly, workpiece loading, preliminary drying, plastic coating, solidifying and workpiece unloading. The invention replaces application of conventional tearproof materials by adding a plastic coating process, the handrail is more beautiful by adopting a surface in the plastic coating process and has better hand feeling; the handrail tube has longer service life, is more environmental, completely accords with ROSH (EU Environmental Certificate), has no damage to a human, and avoids safety hidden dangers; during treatments before cleaning and spraying, two washing steps are added, thereby better cleaning superfluous substances on the surface of a product, enabling subsequent spraying to be convenient, and having better adhesive force and better spraying effect.

Description

(1) Technical field [0001] The invention belongs to the technical field of non-ferrous metal processing, and relates to the development and production process of the handrail of a spinning bicycle. (2) Background technology [0002] The existing spinning handrail production process mainly includes blanking - sawing tube - bending tube (two bends in total) - punch forming - punching - surface grinding to stab - welding - before spraying Treatment (degreasing—washing—pickling—surface conditioning—phosphating—drying)—cleaning (mainly due to uneven surface welds, false welding, etc.)—spraying—curing—using fixtures Fix it - use an air gun to blow the Tearbud into it (in the process of blowing, people have to forcefully insert the Tearbuk) - set it well Tearbuk, remove excess fingerprints and dirt on the surface of the product - use Wrap it in a PE bag and fix the opening with adhesive tape. This kind of process adopts the tear-proof inserting process, and the use of tear-proof ...
