One-time forming Pall ring, their production process has those

Metal Pall ring packing is widely used in chemical industry and other industries. To be used for medium separation, it is an improvement on the basis of Raschig ring. Two rows of windows with inwardly extending tongues are opened on the ring wall, and each layer of window holes has 5 A tongue, this type of configuration improves the distribution of gas and liquid, making full use of the inner surface of the ring. In the prior art, the manufacture of stainless steel Pall rings requires three processes, namely material cutting, bending and rounding, which requires at least two sets of molds, which affects production efficiency and does not use human and material resources reasonably.
The purpose of the invention of the new Pall ring manufacturing process is to make up for the deficiencies of the existing technology and to provide a mold capable of forming a Pall ring in one go. One-shot molding from a Pall ring. The mold includes an upper mold and a lower mold. The lower mold consists of a base and a worktable. The base and the worktable are supported and connected by a guide column. There are two push sliders on one side of the worktable that are parallel to each other, and the other side is provided with a molding touch. It is used to fix the Pall ring. There is also a feeding crucible on the worktable. The lower end of the crucible supplies the tongue mold for making the Pall ring tongue. The upper mold is arranged side by side with the trimming and bending molds. The feed crucible is "ro" shaped. The tongue mold is a knife-shaped mold that is fixedly connected to the base. The tongue mold is divided into two rows of three, and the mold is detachably installed on the punch. After the utility model structure is adopted, the stainless steel Pall ring can be manufactured by using a set of molds, which saves labor. Compared with the existing manufacturing Pall ring, the work efficiency is improved, and the manpower and material resources are greatly reduced.
The specific implementation of Pall ring
The following is a step-by-step description of the specific embodiments of the present utility model. The disposable Pall ring forming die in this embodiment includes an upper die and a lower die. The lower die consists of a base and a worktable. The base and the worktable are supported and connected by guide posts. There are four parallel sliders on one side of the table. The other side is provided with a forming die for fixing the Pall ring into shape. The worktable is also provided with a feeding port, and the lower end of the feeding port is provided with a tongue die for punching out the tongue body of the Pall ring. The upper die is arranged side by side with the cutting edge and the bending die. The feed port is a "mouth" shape. The tongue die is a knife-shaped die, which is fixedly connected to the base. The tongue die is two rows of three in each row. The die is removably attached to the punch. In the working state, the stainless steel plate extends into the feeding port. Punch out the two rows of upwardly extending tongues from the tongue model, and then extend the sliders outwards. The semi-finished product is then cut with a cutting knife. At the same time, the bending die is cut into a "U" shape. After this, the slider is ejected inward and the semi-finished product marked "u" is ejected into the forming die, which is then rounded off to create a stainless steel Pall ring. It changes the current situation that three processes are required for the production of "Pall Ring" by the traditional process, and further improves the production efficiency.
