Description
Technical Field
The utility model relates to a car compartment door hinge technical field, concretely relates to high rigidity punching press formula 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 of 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 later machining working procedures, has extremely high efficiency, does not have the worry of casting/forging defects, but is limited by the structure, the rigidity of the root part of a rotating shaft of the hinge is poorer, and is easy to deform after long-term use or under the action of hidden external force, the stable sealing support for the door system is not sufficient.
Disclosure of Invention
In order to solve the problem that current hinge exists, the utility model provides a high rigidity punching press formula hinge to improve rigidity, guarantee stability.
The invention conception is as follows: in view of the fact that the transition position of a rotating shaft and the hinge body plate surface of the front face of the universal hinge is limited by the processing direction of the rolling lug, the height of the arranged reinforcing convex rib is transited to be 0mm at the position, the rigidity of the universal hinge actually depends on the thickness of the adopted material, but the effect of improving the rigidity by increasing the material thickness is extremely low, a larger space is reserved on the front face by changing the rolling lug direction, the height of the welded rib plate can reach about 10-12mm, and the rigidity of the root part of the universal hinge can be greatly improved on the premise of keeping the thickness of a base body and the processing technology unchanged.
Therefore, the technical scheme of the utility model is that: the utility model provides a high rigidity punching press formula hinge, includes the hinge body, hinge body one end is equipped with the book ear, the other end is the door link, its characterized in that: the door hinge is characterized in that the rolling lug is turned inwards, two reinforcing rib plates extending along the length direction of the hinge body are arranged between one side, close to the connecting end of the door, of the rolling lug and the hinge body, one end of each reinforcing rib plate is fixedly attached to the arc surface of the rolling lug, and the bottom of each reinforcing rib plate is fixedly attached to the hinge body.
The technical scheme is further improved as follows: the hinge body is through stamping forming's bent plate structure, including inside first kink, outside second kink, inside third kink, the kink passes through the arc transition. 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 reinforcing rib plate extends to be connected with the second bending part, and the height of the reinforcing rib plate is gradually reduced through arc transition. On the premise of ensuring the strength, the weight is reduced, and 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 the reinforcing rib plate at one end, which is attached to the lug, is 10-12 mm. The purpose is to increase hinge root stiffness.
The technical scheme is further improved as follows: the width of the hinge body on one side of the connecting end of the vehicle door is larger than that on one side of the rolling lug. The purpose is to increase the contact surface and the welding seam length of the automobile 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, so can be under the prerequisite that does not influence door plant opening angle, the positive high space of maximize hinge sets up twice rib plate in this space and welds on the hinge.
