[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-7 The present invention provides an embodiment of a stamped and welded steel cap manufacturing process, comprising the following steps: Step 1, material selection; Step 2, primary stamping; Step 3, secondary stamping; Step 4, structure selection; Step 5, welding; Step 6, hot-dip galvanizing; Step 7, tapping.

[0031] In step one above, a steel plate material of suitable material is selected as the raw material for preparing the steel cap 2;

[0032] In step two above, the raw material selected in step one is placed under a stamping machine and stamped with a corresponding mold to obtain round steel sheet 1;

[0033] In step three above, the round steel sheet 1 obtained in step two is stamped and stretched to obtain a steel cap 2, and a protrusion 3 is stamped in the steel cap 2 to obtain a locking tooth 4.

[0034] In step four above, a steel sleeve 5 of appropriate size is selected according to the required size of the steel cap 2, and the surface of the selected steel sleeve 5 is ground and polished.

[0035] In step five above, the steel sleeve 5 selected in step four is welded to the protrusion 3 stamped in the steel cap 2. Before welding the steel sleeve 5, the welding surfaces of the steel sleeve 5 and the protrusion 3 need to be cleaned of impurities to improve the welding effect. The welding methods include, but are not limited to, electric arc welding, gas welding and laser welding.

[0036] In step six above, the steel cap 2 with the welded steel sleeve 5 is subjected to hot-dip galvanizing treatment. Before galvanizing, the steel sleeve 5 and the steel cap 2 need to undergo the following treatment steps:

[0037] 1) Thoroughly clean the metal surface with a solvent to remove grease and other impurities;

[0038] 2) Immerse the metal surface in hydrochloric acid solution to remove oxides and rust. Then rinse the immersed metal with clean water several times and dry it after rinsing to ensure that the metal surface is dry and clean.

[0039] 3) The metal is immersed in a hot-dip galvanizing bath, and the formula and immersion time of the hot-dip galvanizing bath are selected according to the material of the metal. During the immersion process, the zinc solution is plated on the surface of the metal by heating to form an alloy layer between the metal and zinc.

[0040] 4) Remove the metal from the hot-dip galvanizing bath and immerse it in an acidic solution to remove excess zinc solution. After immersion, clean the metal to remove any remaining acidic solution and other impurities.

[0041] In step seven above, the galvanized steel cap 2 from step six is ​​fixed by a chuck, and then a tapping device is used to tap the inside of the steel sleeve 5 to obtain a threaded groove 6. Finally, the steel cap 2 is removed from the chuck to obtain the finished stamped and welded steel cap.

[0042] Based on the above, the advantages of this invention are that, when used, it improves the original manufacturing process and technology of cast steel caps, changing the high-temperature and high-heat casting production to steel plate stamping and forming, then welding the steel sleeve 5 and surface treatment, and finally tapping. This changes the existing processing method and solves the problems of high manufacturing cost, low efficiency, long production cycle, and defects in the internal and external appearance of the product.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
