Description
Technical Field
The invention belongs to the technical field of automobiles, and particularly relates to a pre-bending and pressing integrated edge covering mechanism.
Background
In the manufacturing process of the automobile body, some parts are formed by combining an inner plate and an outer plate through edge covering, such as assembly parts of a four-door assembly, an engine cover assembly, a trunk lid assembly and the like of an automobile. The edge covering modes of the outer plate and the inner plate of the automobile covering parts comprise press die edge covering, special machine edge covering and robot edge rolling. The press-fit die edge covering is characterized in that a press-fit die is arranged on an oil press, and the pressure of the oil press is utilized to implement two processes of pre-bending and pressing, so that the press-fit die edge covering has the advantages of easiness in control of edge covering size, stable quality, mature technology, high edge covering efficiency, quick pressing rhythm and the like, and is widely adopted.
The front door assembly, the outer door plate and the inner door plate assembly of a certain vehicle type form a front door assembly part. The outer plate and the inner plate are buckled at the surrounding positions of the edges, and the surrounding of the inner plate assembly is wrapped to form a closed cavity. The process of pressing and binding the mold is generally divided into two steps of pre-bending and pressing, and the process diagram of pressing and binding is shown in figure 1. Taking the front door assembly part as an example, the pressing and edge covering process is as follows: after the inner plate sub-assembly is placed into an outer plate single piece (the outer plate single piece state when the mark A is formed), the outer plate sub-assembly is placed into a pressing edge-covering die arranged on an oil press, and a pressing die is driven by the oil press, so that the process of pre-bending the outer plate single piece (the outer plate part is in the outer plate single piece state shown by the mark A to the outer plate pre-bending state shown by the mark B) is firstly completed, and then the process of pressing the outer plate single piece (the outer plate pre-bending state shown by the mark B to the pressing assembly state shown by the mark C) is completed; and finishing the whole pressing and edge covering process of the outer plate and the inner plate.
The traditional pressing and edge covering mechanism is shown in figure 2 and consists of a pre-bending knife arranged on a lower die and a pressing knife arranged on an upper die. The edge covering process of the outer plate single piece by the pressing die is as follows: firstly, the upper die 24 is driven in the descending process of the oil press, the four-link pre-bending mechanism 23 which is arranged on the lower die and is used for fixing a pre-bending knife is driven, the pre-bending knife finishes the process of moving from an initial state 21 to a pre-bending state 22 and then returning to the initial state 21, and pre-bending of the outer plate single piece is realized; finally, the pressing cutter block 25 arranged on the upper die body 24 is in abutting joint with the moulding bed 26 fixed on the lower die body, so that the pressing of the single outer plate after being pre-bent is completed.
For the press-fit binding (the other positions are also applicable) at the front door and window frame, the binding position is provided with a structure of a double-layer inner plate, so that when the traditional press-fit binding mold is designed, the condition that an upper mold press-fit cutter cannot interfere with the upper inner plate is considered, namely, the traditional press-fit binding mold has special requirements on product parts. As shown in the press-fit taping process diagram of fig. 1, when a key point (mark M) of an inner plate subassembly approaches or exceeds a press-fit knife edge line (mark N) arranged on an upper die, a conventional press-fit knife will suffer from insufficient strength or cannot be arranged; at the moment, if the edge covering process of the press-fit die is still adopted, or the structure of the product is changed, or the poor edge covering state is barely accepted, or the edge line (mark N) of the press-fit knife is avoided by a method, namely the press-fit edge covering process of the traditional press-fit knife on the upper portion is changed; otherwise, only a special machine with relatively high cost or a robot binding process with relatively low efficiency can be adopted.
