The existing vacuum cup is generally straight, and can realize the function of drinking water, but in the process of drinking water, a drinker needs to lift the head and the vacuum cup upwards to a greater extent to normally drink the liquid in the vacuum cup, on one hand, the user is more laboursome, on the other hand, the user can cause the situation of water choking sometimes, and further improvement is needed.
Disclosure of Invention
The invention provides a novel method for manufacturing a vacuum cup with an inclined head, aiming at the defects that the straight vacuum cup in the prior art is labor-consuming in the process of drinking water and can cause water choking sometimes.
In order to solve the technical problems, the invention is realized by the following technical scheme:
a method for manufacturing a vacuum cup with a tilted head comprises the following steps:
a. manufacturing a special-shaped outer shell:
a1, taking a first pipe fitting, and reducing the head of the first pipe fitting to form a temporary opening;
a2, cutting the temporary opening, and then performing sand blasting and annealing operations on the surface of the first pipe fitting to obtain a semi-finished shell product;
a3, performing water expansion on the semi-finished shell product to obtain a special-shaped shell blank, wherein a shell joint line is formed on the special-shaped shell blank;

b. manufacturing the inner container connecting piece:
b1, taking a second pipe fitting, and pretreating the second pipe fitting, wherein the pretreatment comprises pipe cutting, welding line pressing and pipe rolling;
b2, performing water expansion, cup separation and stretching operations on the second pipe fitting to obtain a blank of the inner container connecting piece;
b3, performing head cutting operation on the blank of the inner container connecting piece, and then flattening and flatly flattening to obtain the inner container connecting piece;
c. manufacturing a special-shaped liner head:
c1, taking a circular sheet, stretching the circular sheet, and stretching to obtain a head prototype;
c2, performing cowhells expansion on the head primary form, and then performing water expansion to obtain a liner head blank body, wherein a liner head joint line is formed on the liner head blank body;
c3, performing bottom cutting, opening flattening and head cutting operations on the inner container head blank body to obtain the special-shaped inner container head;
d. manufacturing a special-shaped inner container:
d1, welding the lower end face of the special-shaped liner head and the upper end face of the liner connecting piece after being aligned to obtain a semi-finished product of the special-shaped liner;
d2, taking a liner bottom, aligning the upper end surface of the liner bottom with the lower end surface of the special-shaped liner semi-finished product, and then welding to obtain the special-shaped liner;
e. aligning a shell joint line on the special-shaped shell body with a liner head joint line on the special-shaped liner, and then aligning and welding an opening part of the special-shaped shell body with an opening part of the special-shaped liner to obtain a vacuum cup prototype;
f. taking a shell bottom, aligning the upper end surface of the shell bottom with the lower end surface of the vacuum cup prototype, and then welding to obtain a vacuum cup blank;
g. and carrying out vacuum pumping operation on the vacuum cup blank body to obtain the vacuum cup with the inclined head.
The steps a1 to a5 are used for manufacturing the special-shaped shell blank, the conventional cup is generally subjected to water expansion and then necking in the manufacturing process, the shoulder part of the shell body after the water expansion is used for positioning, and the necking position is in arc transition.
In the step a2, the cutting opening is used for removing the redundant waste materials generated after pipe shrinking, in addition, the hardness of the material at the position of the pipe shrinking position can be changed after the pipe shrinking, and a spinning mark can be generated on the surface of the first pipe fitting after the pipe shrinking, so that the first pipe fitting can be softened through the subsequent annealing operation, and the size of the shell semi-finished product can be kept stable after the water expansion process. In addition, because the shape of the special-shaped shell blank after water expansion is complex, the sand throwing operation is difficult at the moment, so the sand throwing operation is preposed, and the sand throwing difficulty can be reduced.
In the step a3, the irregular shape of the special-shaped shell blank is formed by using a water expansion process, so that the special-shaped shell blank is easy to form. In the step a4, the operation of bottom finishing and bottom flattening is to obtain a plane with a regular circle opening and bottom, so as to facilitate the subsequent welding, and in addition, the cut bevel opening is used for welding with the thread head to form a thread opening part. Step a4 and step a5, the thread head and the bevel are processed separately, so that the problems that the integral forming difficulty of the head inclined vacuum cup is high, and the alignment requirement of the cover and the thread head is high, namely the alignment requirement of the cover and the head inclined vacuum cup is high can be well solved.
And step b is used for manufacturing the inner container connecting piece, wherein step b1 is more convenient for subsequent water expansion operation on the second pipe fitting through pretreatment operation, and step b2 is subjected to cup splitting and stretching operation after the water expansion operation is performed, and is subjected to head cutting, flat opening and flat bottom operation in step b3, so that the forming process of the inner container connecting piece can be divided into a plurality of small steps, and the inner container connecting piece is more easily processed.
And c, manufacturing the special-shaped liner head, wherein the head prototype is processed in the step c1 firstly, so that the shape of the head prototype is approximately close to the shape of the final special-shaped liner head, and then the liner head blank is obtained through the beef tendon expansion and the water expansion in the step c 2. The reason why the ox tendon is expanded is that the ox tendon is not sealed in the expansion process, so that the resistance and the thrust are not generated when the ox tendon is compressed to expand, the head prototype is low in thinning degree and not easy to expand and break, then the water expansion is performed to obtain the inner container head blank body with the shape and the precision meeting the requirements, finally, the step c3 is performed to obtain a plane with a regular circle at the mouth and the bottom, and the welding in the subsequent process is facilitated.
And d, welding the special-shaped liner head, the liner connecting piece and the liner bottom to form the special-shaped liner, and solving the problem of high difficulty in integrally forming the special-shaped liner through step-by-step processing and centralized welding of all parts.
And e, f and g are used for welding the special-shaped outer shell, the special-shaped inner container and the bottom of the outer shell to form a vacuum cup blank, wherein the outer shell joint line is aligned with the inner container head joint line before welding, the direction of the irregular special-shaped outer shell is consistent with that of the irregular special-shaped inner container, the problem that a follow-up vacuum layer fails due to contact of the side walls of the special-shaped outer shell and the irregular special-shaped inner container in the matching process is avoided, the final head inclined type vacuum cup is obtained through vacuumizing operation, and the problem that the manufacturing difficulty of the head inclined type vacuum cup is high is solved through step-by-step processing and centralized welding of all parts.
Through the steps, the vacuum cup with the inclined head can be manufactured, so that the problems that people need to drink water difficultly and water choking happens sometimes are solved.
