Description
Technical Field
The utility model relates to a car railway carriage or compartment door hinge technical field, concretely relates to high rigidity hinge.
Background
The hinge is used as a connecting and rotating device between a door plate and a door frame, the requirements on strength and rigidity are higher, the current universal manufacturing mode is divided into a stamping mode and a casting/forging mode, the casting/forging mode can obtain better balance between the strength and the rigidity due to free modeling, but the casting mode gradually loses competitiveness under the increasingly strict environmental regulations due to huge energy consumption, high environmental pollution and time and labor consumption in later machining, relatively speaking, the forging mode has lower environmental pollution degree, but still does not avoid the problems of high cost, low efficiency and the like caused by energy consumption and machining, and the stamping type hinge is manufactured by adopting the working procedures of stamping, rolling ears and the like, does not need the working procedures of later machining, has extremely high efficiency, does not have the worry of casting/forging defects, but is limited by a structure, the rigidity of the root part of a rotating shaft of the hinge is poorer, is easy to deform after long-term use or under the action of hidden external force, and has insufficient stable sealing support performance on a door system.
Disclosure of Invention
In order to solve the problem that current hinge processing exists, the utility model provides a high rigidity hinge to improve rigidity, guarantee stability.
The invention conception is as follows: since the hinge of the universal type uses the rolling lug to connect the rotating shaft, the hinge body part of the structure is limited by the rolling lug to increase the strength. The inventor is realizing the utility model discloses an in-process considers replacing the steel pipe for the eye, but hinge body part free design strengthening rib structure to promote root rigidity, the long-term stability that keeps of hinge.
Therefore, the technical scheme of the utility model is that: the utility model provides a high rigidity hinge, includes the hinge body, hinge body one end is the pivot link, the other end is the door link, its characterized in that: the hinge body is close to pivot link one side end and is equipped with outside punching press protruding muscle along length direction, and the tip of hinge body and punching press protruding muscle has the steel pipe sleeve that the steel pipe cutting formed through welded fastening.
The hinge body is a bent plate structure formed by stamping and is provided with an inward first bent part, an outward second bent part and an inward third bent part, and the bent parts are in transition through a large arc. The purpose is that the installation space who provides door sealing device and guarantee that railway carriage or compartment door opening angle can reach 270 degrees, improves the intensity of hinge simultaneously.
The angle of the first bending part is 135 degrees, the angle of the second bending part is 158 degrees, and the angle of the second bending part is 158 degrees, so that the installation space of the sealing device is ensured, and the opening angle of the compartment door is ensured.
The punching press protruding muscle extends to and links up with second buckling part from the pivot link end, and the protruding muscle of punching press is V type structure, and the height of the protruding muscle of punching press increases progressively from one end gradually, steadilys decrease again gradually. On the premise of ensuring the strength, the interference with other parts after the compartment door is opened for 270 degrees is avoided.
The width of the hinge body on one side of the vehicle door connecting end is larger than that of the rotating shaft connecting end. The purpose is to increase the contact surface and the length of a welding seam with the vehicle door and increase the stability.
Has the advantages that: the utility model discloses change the pivot link into by general steel sheet eye processing mode and replace by the steel pipe, pivot mounting hole precision height need not any processing, hinge body part does not receive the eye restriction promptly simultaneously, protruding muscle structure is strengthened in design that can be free, adopt great protruding highly to reach the purpose of high rigidity, rethread high quality welding mode (if adopt the robot welding) to connect, gain better balance between high accuracy, high rigidity, high efficiency, processing is convenient, the cost of manufacture is low.
