The invention discloses an adjustable double-cover pressing type pressure vessel which comprises a tank body, a tank cover, a height adjustable mobile bracket and an adjustable pressing device. The tank cover is mounted on the tank body. The adjustable pressing device is mounted on the mobile bracket. An upper ring mounting plate and a lower ring mounting plate are arranged at the connection part between the tank cover and the tank body. A hydraulic opening is formed in the tank cover. A detachable hydraulic cover is arranged on the hydraulic opening. The pressing device is mounted on the mobile bracket, and the mobile bracket can drive the pressing device to move, and therefore, the pressing device is not limited to one pressure vessel, and can be moved to press another pressure vessels; and the positions of arc-shaped pressing plates are adjusted through the mobile bracket, so that the pressing positions of the arc-shaped pressing plates are more accurate.

The invention relates to installation equipment for a radiator water chamber of a combustion engine, in particular to a roller press for installing the radiator water chamber of the combustion engine. The roller press comprises two case bodies which are arranged side by side. Longitudinal guide rails are arranged in each case body. The longitudinal guide rails in each case body are connected with a longitudinal sliding plate in a slidable mode. A transverse sliding plate is arranged on each longitudinal sliding plate. One end of each transverse sliding plate is connected with a rolling wheel. The other end of each transverse sliding plate is connected with a cam mechanism which is used for driving the transverse sliding plate to feed in the transverse direction. The longitudinal sliding plates do reciprocating motion along the longitudinal guide rails through driving mechanisms which are connected with the bottoms of the longitudinal sliding plates. The driving mechanisms in the two case bodies are connected through a second chain wheel and chain transmission mechanism. Any driving mechanism is connected with a motor through a first chain wheel and chain transmission mechanism. A main slice to be pressed and the water chamber to be pressed are arranged between the two case bodies and are formed by the rolling wheels on the two case bodies through rolling. The rolling wheels of the roller press can run automatically, can automatically complete press fitting to the main slice and the water chamber, can automatically stop after rolling is completed, and can work in a reciprocating mode. The roller press is free from empty running strokes and high in working efficiency.

The invention discloses a double-sided opposite pressing interior trim molding hydraulic press which comprises a rack formed by fixedly connecting vertical columns, an upper crossbeam and a side frame, wherein, an upper oil cylinder is fixedly installed on the upper crossbeam, the piston end of the upper oil cylinder is connected with an upper sliding block, a lower sliding block is driven by a stretching oil cylinder, and the upper and lower sliding blocks respectively slide along upper and lower guide columns; rotating axles are respectively installed on the front, rear, left and right sides of the upper end surface of the upper sliding block and the lower end surface of the lower sliding block, the adjacent rotating axles are meshed for transmission through bevel gears, synchronous gears are respectively installed at the both ends of the rotating axles positioned on the left and right sides, and the synchronous gears are respectively meshed with balancing racks installed on vertical columns on the adjacent sides of the synchronous gears. The invention realizes movement during the process of sliding up and down, the density of the interior parts oppositely pressed is good, the productive tempo is quickened, the thickness of the pressed interior trims is even, the comfort level and the beauty of the interior trim shaped parts are improved, and the higher-level production facilities are provided for the shaped interior trim manufacturers at home and abroad.

The invention discloses a double-cover pressing type pressure vessel. The double-cover pressing type pressure vessel comprises a tank body, a tank cover mounted on the tank body, a height-adjustable movable bracket and a pressing device mounted on the movable bracket, wherein an upper ring mounting plate and a lower ring mounting plate are respectively arranged at a junction between the tank cover and the tank body; a hydraulic opening is formed in the tank cover; a detachable hydraulic cover is mounted at the hydraulic opening; a sealing cover body in the middle of the hydraulic cover is divided into two door covers which are articulated with the upper part of the edge of the hydraulic cover. According to the double-cover pressing type pressure vessel, the connection manner between the tank cover and the tank body is a pressing manner; a ring pressing plate is mounted on a hydraulic driving device on the movable bracket via a transverse rod and a vertical rod; the hydraulic driving device is used for driving the ring pressing plate to press the upper ring mounting plate down, so that the upper ring mounting plate can be tightly pressed on the lower ring mounting plate; the double-cover pressing type pressure vessel is extremely convenient to mount.

The invention discloses a dual compression pressure vessel with two cover bodies. The dual compression pressure vessel comprises a tank body, a tank cover mounted on the tank body, a height-adjustable movable support, and a compression device mounted on the movable support, wherein an upper circular ring mounting plate and a lower circular ring mounting plate are arranged at the joint between the tank cover and the tank body; a hydraulic opening is formed in the tank cover; and a detachable hydraulic cover is mounted above the hydraulic opening. The dual compression pressure vessel provided by the invention has the advantages that two door covers are closed in a compression type; the door slots of the two door covers can be totally pressed and blocked by a strip pressing plate which is mounted through a second hydraulic cylinder, so that the door covers are very convenient to open and close; a sealing rubber mat is arranged on the strip pressing plate, so that the sealing performance can be improved after the door slots are pressed and pressure leakage can be avoided; and clamping blocks arranged on the stripe pressing plate can press into clamping grooves formed in the door covers, so that not only can the positioning function be achieved, but also the stability and the anti-impact capability can be improved, and the door covers can be prevented from being opened due to excessive pressure or unexpected reasons.
