Description
Technical field:
The present invention relates to the hydraulic-machinery compound synchronization mechanism of veneer hot press of the medium-and-large-sized single-layer hot press of wood-based plate industry.
Background technology:
At present, the wood-based plate single-layer hot press is the home and abroad no matter, continues to use conventional hydraulic synchronized or similar method always.This method synchronization accuracy is low, Hydraulic Elements performance requirement height, operation inconvenience.Single-layer hot press is the artificial board product line capital equipment, and its synchronization accuracy directly influences the quality of the product of compacting, even causes the damage of equipment.Therefore, develop a kind of hydraulic-machinery compound synchronization mechanism of veneer hot press is home and abroad new problem anxious to be solved always.
Summary of the invention:
Provide that a kind of novel science, technology are easy to manufacture, simple in structure order of the present invention, reliable operation, hydraulic-machinery compound synchronization mechanism of veneer hot press easy to adjust.
The object of the present invention is achieved like this: this device is made up of hydraulic pressure synchronization loop, mechanical synchronizer, and the hydraulic pressure synchronization loop is installed in the conduit under fluid pressure, and mechanical synchronizer is installed in the top of hot press by the bearing block of rotating assembly; When walking beam rose or descend, each plane of mechanical synchronizer forced motion crossbeam was maintained at the same horizontal plane; Be installed in the hydraulic pressure synchronization loop in the conduit under fluid pressure, per two hydraulic cylinders along the diagonal symmetric arrangement are formed one group, and the oil-out of first hydraulic cylinder connects the oil-in of another hydraulic cylinder; Machinery composite sync mechanism is by rotating assembly, the toggle link assembly, rod assembly, the disk spring assembly, articulated mounting, link assembly is formed, rotating assembly has the 2-6 group, every group comprises an elongated rotating shaft, pair of bearing is equipped with at its two ends respectively, a pair of toggle link, each toggle link is made up of 90 ° of two pole in two groups of intervals, wherein a pole links to each other with pull bar, the other end of pull bar passes through spring, bearing pin is connected with moved cross beam, another pole links to each other with connecting rod, the other end of connecting rod is connected with another toggle link, and toggle link is installed in the rotating shaft two ends of rotating assembly by the flat key at 90 ° at two intervals, and the pull bar upper end is by the globular hinge head, bearing pin links to each other with toggle link, the lower end links to each other with the disk spring assembly by the threaded adjustment device, and the disk spring assembly comprises 2-6 disk spring, the guide locating device provided composition; The lower end of disk spring assembly is connected with the bearing pin that is welded on moved cross beam upper articulation device by the globular hinge head; Connecting rod is to be become with the round steel solder side by seamless steel pipe, and its top processes the pin-and-hole that links to each other with each toggle link.
Main points of the present invention are the structure and the principle of hydraulic-machinery compound synchronization mechanism of veneer hot press.This organization hydraulic pressure synchronization loop is realized the uniform distribution of hydraulic coupling, and the toggle link of the mechanical synchronization mechanism of this mechanism is equivalent to the crank of crank-rocker mechanism, and every cover toggle link is a driving element, is again drive element.In real work, be as driving element, still as drive element, be to determine the approximate obedience principle that the minority is subordinate to the majority at any time according to the duty of system.When moved cross beam a bit was below or above assigned address in process of rising or falling, when promptly being higher or lower than on the crossbeam most of pull bars position, the pull bar that links to each other with this point was subjected to corresponding toggle link effect, spur or the promotion moved cross beam to assigned address.Connecting rod is in the tension or the duty of pressurized, according to its job specification of continuous toggle link determine.Spring adopts the bigger disk spring of rigidity, and in order to the foozle of compensation lazy-tongs, the rigidity of connecting rod is vital in whole lazy-tongs.The hydraulic pressure synchronized is installed in the conduit under fluid pressure, and when walking beam rose or descend, each plane of mechanical synchronizer forced motion crossbeam was maintained at the same horizontal plane.
Hydraulic-machinery compound synchronization mechanism of veneer hot press compared with prior art has that novel science, technology are easy to manufacture, simple in structure, a reliable operation, advantage such as easy to adjust, will be widely used in the wood-based plate manufacturing.
