Medicine pot integrated molding construction method

The invention relates to a medicine pot integral molding construction method, which mainly uses a hydraulic press or a hydraulic machine to inject liquid into a work object and closes, and then deforms the work object by hydraulic pressure, so that the work object is integrally formed according to the shape of the mold. It is a medicine pot and there are no seams at all.

According to the production process of the traditional medicine pot, it is quite complicated and complicated. Please refer to the drawing diagram of Figure 1 for the processing of the body forming. The metal plate is pulled three times (three different molds) into an inverted U shape to make it The upper body 10 of the body 1 is then cut and flattened by the outer end of the convex ring 101 to make the upper body 10 relatively flat, and then the top surface of the upper body 10 is cut into holes, so that the upper body 10 generates the opening 102 (as shown in Fig. 2). And the top ring edge 103 of the upper body 10 is bent inwardly (using a three-attached mold) to avoid sharp cuts after punching, and when the upper body 10 is cut, the upper body 10 is expanded downward, so The upper body 10 must be pressed inwardly by another die to return it to its original width to engage the lower body 11.

As for the lower body 11 of the kettle body 1, the metal plate is drawn four times (four different molds are attached) to make the thickness uniform, and a W shape is formed, and the convex ring 111 of the top outer expansion is cut, and then the cut surface is cut. The flattening is performed to connect with the upper body 10, and when the lower body 11 is formed, an external opening angle is also generated. At this time, the outer expanded body 11 is pressed inwardly to return the lower body 11 to the original width so as to The upper body 10 is connected.

When assembling, please continue to refer to FIG. 2, and the trimmed upper body 10 and the lower body 11 are correspondingly welded 16 to form a pot body 1, and the welded joint 16 is polished to make it smooth and seamless (as shown in Fig. 3). As shown in the figure), the pot body 1 is then punched in one side, and the filter hole 13 can be produced, and the end of the filter hole 13 is smoothed and trimmed, and then the formed spout 12 (formed by the three attached molds) and the pot The body 1 is welded, and the spout 12 is corresponding to the filter hole 13 so that the liquid medicine in the body 1 is poured out from the spout 12.

Therefore, a pot body 1 is formed by drawing and smoothing the upper body 10 and the lower body 11 several times, and then the pre-punched spout 12 is welded to the pot body 1 with the filter hole 13 of the die, and then the pot is welded. A heating device (not shown) is disposed under the body 1, and a handle 14 is disposed on the side, and a cover 15 is disposed on the upper side, that is, the body 1 (as shown in FIG. 3), and the above complicated procedures are integrated. The kettle body 1 requires more than twenty processes to complete the production. Among them, when the metal plate is pulled, it is easy to cause damage and deformation, and the defect rate is about (15% to 20%), which leads to an increase in cost, which is a pity, especially when the upper body 10 and the lower body 11 of the body 1 are pulled. Different molds are required, so in order to speed up the molding operation, multiple sets of molds and equipments are required to connect the production of each process. Therefore, not only the equipment requires more space and more labor costs, but also is time consuming to manufacture. Laboriously, the production cannot be rapidly improved, and the economic benefit is poor, and the body 1 is welded by the upper body 10 and the lower body 11, so the strength is poor.

The inventor is specialized in the manufacture, sale and research and development of various pots and pots. He knows that the pot body is quite cumbersome to manufacture, cannot mass-produce, and has a high defect rate (15~20%), plus raw materials and personnel. The cost is quite high and the economic benefits are not good. Therefore, it is a hard work to solve the problem. With its own professional and years of work experience, it has finally invented a hydraulic forming method after several revisions, tests and improvements. Complete the body that is truly integrated.

The invention relates to a method for integrally forming a medicine pot, in particular to a method for directly forming a pot body by using a hydraulic method, so that the pot body can be integrally formed, which not only increases the strength of the pot body, but can omit complicated manufacturing processes, and does not It will produce defective products, which saves time and effort. The utility model firstly hydraulically presses the work object into a U shape by a U-shaped mold, or shapes the shape by using oil pressure, and the work object is a metal plate, and the required material is cut out with the kettle body to avoid waste of too much sheet material. When the metal plate is directly pressed into a U shape by a hydraulic machine, and the surface is still smooth and flat, and then the flange of the workpiece is cut with the trimming die, which removes the excess sheet material of the workpiece ring to make the work The material can conform to the forming plate of the kettle body, and then the U-shaped plate material is placed into the kettle body mold, and the liquid is injected into the work object and tightly closed. At this time, the work object is filled with liquid, and the hydraulic machine is pressed and formed, and then cooperated. The pressurization of the hydraulic press causes the work object to be deformed according to the shape of the pot body mold, so that the work object is pushed by the high pressure in the liquid, and the flow expands and fills the mold, so that the work object is integrally formed into the kettle body. Finally, the punching die is used to punch the spout to produce a water hole, so that the liquid in the kettle body can be discharged from the water hole. It flows out, so the pot body is made quickly and completely without defective products, which is ideal and progressive.
