Liquefied Cylinder Manufacturing Machine


Cylinders are widely used in industrial production for the filling of high pressure air, oxygen, nitrogen, argon, carbon dioxide and storage of compressed natural gas (CNG) in automotive power systems. Stamping method is now more common method of manufacturing steel seamless cylinders, it can be relatively easy to get a variety of diameter and wall thickness of the cylinder. LPG Gas Cylinder Body Manufacturing Machine Stamping method of manufacturing seamless steel cylinders mainly include the following steps vertical stamping, preform drawing, closing and so on. Stamping method is the key to the manufacture of cylinders is stamping out of the preform into a predetermined length and uniform wall thickness of the cylinder. The conventional liquefied cylinder block manufacturing machine is generally composed of a drawing die, a ring mold and a rolling die provided on the same straight line, and the drawing die is composed of a die rod and a die, and the die end of the drawing die is driven The hydraulic cylinder is connected and the die end of the drawing die is used to push the preform cavity, and the preform is passed through the center hole of the ring mold and the rolling mold. When the hydraulic cylinder is in operation, LPG Gas Cylinder Body Manufacturing Machine the entire drawing die is pushed into the ring mold and the rolling die so as to press the preform wall on the entire drawing die to draw the preform. (192 400mm) and length (120 (T2000mm)), the cooling die has a cooling water circulation system. Since the cooling water has its own weight, the drawing die length is longer than that of the cooling water. Long, leading to the upper and lower drawing die cooling uneven, easy to mold rod bending deformation, short service life; cylinder out, wall thickness deviation, does not meet the product requirements and other issues.

DISCLOSURE OF THE INVENTION The utility model provides a drawing die for a liquefied gas cylinder manufacturing machine for a steel seamless gas cylinder, LPG Gas Cylinder Body Manufacturing Machine which solves the problem that the cooling water is unevenly cooled due to the self-weight. An elongated mold for a liquefied gas cylinder manufacturing machine for a seamless steel cylinder, comprising a die, a die rod and a mold base connected in series, said die being provided with a cooling chamber, said die The water inlet hole is arranged on the side wall, and the inlet pipe is connected with the water inlet hole and the other end into the cooling chamber. The water inlet pipe is provided with a water inlet pipe And an outer edge of said baffle plate abuts against the inner wall of the cooling chamber. LPG Gas Cylinder Body Manufacturing Machine Wherein the mold hole is provided with a central hole for receiving the inlet pipe, one end of the center hole is vertically communicated with the water inlet hole and the other end is communicated with the cooling chamber; a gap between the inner wall of the center hole and the wall of the inlet pipe And the middle of the rod is provided with a water discharge hole communicating with the gap. The inlet pipe has a sealing ring between the end end of the inlet pipe and the inner wall of the central hole to prevent the cooling water from flowing back into the water inlet hole. The center hole is provided with a fixed ring between the end of the cooling chamber and the center tube. The center hole is arranged through the molding rod, and is close to one end of the molding base to be sealed with a cover plate for easy manufacture. The spiral guide plate gradually increases or decreases gradually from the one end to the other end of the die rod, and the cooling effect can be increased by using the equal diameter margin structure. LPG Gas Cylinder Body Manufacturing Machine The utility model is provided with a spiral guide plate on a part of the wall of the cooling chamber. The cooling water flowing out of the water inlet pipe can be spirally flowed into the mold rod to avoid the uneven cooling due to the self-weight of the cooling water The problem.
