Description

Apparatus for manufacturing various types of valves by forging process {Apparatus for valve of various type of forging method}

The present invention is to solve the problem of durability and appearance by the conventional casting molding in the manufacture of various types of valves, the manufacturer wants to heat the valve member of the cylindrical material of the cylinder shape in the blocked state After seating on the lower mold of the shape and pressing the press of the same shape as the lower mold to produce the shape of the desired valve member, the chip of the outer peripheral surface is punched with a cutter, and then stored in the thunder machine to polish and polish the surface and then the lower By manufacturing the valve so that it can be used for the intended use by drilling on the mold and drilling it in the desired position and tapping, it can show more excellent effect on durability and beauty than the casting molding method of manufacturing the valve. The present invention relates to an apparatus for manufacturing various types of valves by forging.

In the related art, the process of manufacturing various valves mainly uses a casting molding method. In brief, the process is described first, crushing iron ore or waste iron, and then sorting the crushed iron ore or waste iron into a heating furnace. It is common to heat the selected iron ore until it is iron, and then, the iron is poured into a mold of a form that is suitable for use, that is, suitable for use, and subjected to tab processing through a cooling process for a predetermined time, and then plated on the surface to be manufactured as a finished product.

First of all, the above method is not economical because its working process is complicated and inefficient, and there is a problem in mass production, and in particular, the general valve manufactured by the above method is weak in durability and may cause cracks or breakage during long-term use. In addition, the appearance is not good, there is a problem to use in luxury mansions or other businesses.

In addition, as the durability problems frequently occur as described above, the matters to be easily solved by simply replacing the valves include many problems in terms of economic and time, such as repair or removal of the entire pipe.

However, the present invention is to solve the above problems by using a forging method in the manufacture of the valve, first, briefly described forging is a forging is a mechanical shape that beats or pressurizes a solid metal material with a hammer or the like It can be defined as an operation to make it, and the tapping temperature may be at room temperature, but in a material with a high melting point, it is often necessary to heat it somewhat. In general, forging at a higher temperature on the basis of the temperature at which recrystallization proceeds in the material is called hot forging, and forging at lower temperature is called cold forging, and free forging and concave angle are produced by tapping between flat tools. It can be largely divided into mold forging, which makes the product of the desired shape by sandwiching the material between one mold.

The present invention is to produce the valve by using the forging in the above type by producing a valve that is simpler and more durable than the production by the conventional casting method and the durability of the plating treatment process or iron ore used in the conventional method Its purpose is to be able to produce mass-produced valves with simple appearance and simple appearance by omitting the sorting process.

Specific means for achieving the above object is the frame member is formed on the bottom surface of the valve member insertion grooves of various shapes in order to forge a desired shape by heating the valve member made of a copper material of the cylinder shape blocked inside. The bottom mold is formed integrally with the bottom surface and formed with a pivoting machine for forward and backward movement in the center of the frame, and for forging and pressing the valve member in the bottom mold in the same shape as the bottom mold. A pressing press having various shapes of insertion grooves formed on the surface thereof, a cutter for punching the chip on the surface of the pressurized valve member, and a surface of the valve member in which the chip of the surface is punched by the cutter. Desiring of a bolting machine for polishing and polishing, and a valve member polished and polished by the machine It is a perforated drill machine key group, and the other main surface and out to study the use suited to] groups are bonded tapping machine for processing tap to the use of the valve member perforated group the drill machine for the position and in that the constructive features.
