Description
Technical Field
The utility model relates to a car railway carriage or compartment door hinge technical field, concretely relates to integral type punching press 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 problems of the existing hinge processing and the existing structure, the utility model provides an integral type punching press hinge to improve rigidity, guarantee stability.
The invention conception is as follows: the transition position of the rotating shaft of the front face of the universal hinge and the surface of the hinge is limited by the processing direction of the rolling lug, the height of the arranged reinforced convex rib is transited to be 0mm at the position, so the rigidity of the hinge actually depends on the thickness of the adopted material, but the effect of improving the rigidity by increasing the thickness of the material is extremely low, so the direction of the rolling lug is considered to be changed, a larger space is reserved at the front face of the hinge, the transition position of the rolling lug and the body on the hinge is provided with the stamping convex rib, the height of the stamping convex rib reaches about 10mm, the stamping convex rib is welded and reinforced between the rolling lug and the body, the structure can greatly improve the rigidity of the root part of the hinge on the premise of keeping the thickness of the base body unchanged and the processing technology unchanged.
Therefore, the technical scheme of the utility model is that: the utility model provides an integral type punching press hinge, includes the hinge body, hinge body one end is equipped with the eye, the other end is the door link, its characterized in that: the door lock is characterized in that the rolling lug is an inward-turning rolling lug, a rectangular release groove hole is formed in the width direction of the starting position of the rolling lug, an inward stamping convex rib is formed on one side, close to the door connecting end, of the rectangular release groove hole through stamping, the stamping convex rib extends towards one side of the door connecting end, and the stamping convex rib is attached to the arc surface of the rolling lug and fixed through welding.
The technical scheme is further improved as follows: 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 technical scheme is further improved as follows: 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 technical scheme is further improved as follows: the stamping convex rib extends to be connected with the second bending part, and the height of the stamping convex rib is gradually decreased progressively. On the premise of ensuring the strength, the interference with other parts after the compartment door is opened for 270 degrees is avoided.
The technical scheme is further improved as follows: the diameter of the lug is 24mm, and the height of one end, attached to the lug, of the stamped convex rib is 10-12mm.
The technical scheme is further improved as follows: the width of the hinge body at one side of the connecting end of the vehicle door is larger than that of the spring eye. 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 general book ear processing direction into inside book by outside book to through the protruding muscle of the inside punching press of stamping forming, so can be under the prerequisite that does not influence door plant opening angle, the high space of the protruding muscle of the inboard (positive) punching press of maximize hinge.
