Among them, the Hair-pin (U-pin) is also called a hairpin because of its winding shape. The Hair-pin winding process is a process route widely adopted at home and abroad at present, and the main process flow is as follows: inserting insulating paper, forming a hairpin, plugging wires, flaring, twisting heads, welding, paint/powder dripping and electrical measurement. The hairpin forming comprises straightening, peeling, cutting and bending the enameled flat copper wire into a U shape.
Referring to fig. 1, a conventional flat wire stator U-PIN molding device is shown. The automatic feeding device comprises an outer die 3 which is fixedly arranged, a feeding frame 2 is arranged at the opening end of the outer die 3, an inner die 4 which is matched with the outer die 3 along the horizontal direction and a pressing die 5 which is arranged opposite to the outer die 3 along the vertical direction. The specific process of U-PIN molding is as follows: the flat copper wire subjected to straightening and paint removal is placed on the feeding frame 2, the inner die 4 is driven to move towards the outer die 3, and the inner die 4 pushes the flat copper wire 8 on the feeding frame 2 to enter the outer die 3 and abut against the profiling surface in the outer die 3, so that the flat copper wire 8 is formed in a 2D (two-dimensional) mode in a plane. And then the pressing die 5 moves towards the outer die, and the flat copper wire 8 is integrally pushed downwards to be propped against the profiling surface of the inner die, so that the flat copper wire 8 is formed in a 3D mode in space.
The prior device has the following problems:
1. is unfavorable for the molding of products. Referring to fig. 2, a schematic diagram of a variation of a flat wire in a 2D molding process of a conventional U-PIN is shown. After the flat wire is pushed into the outer die by the inner die, the resistance on two sides is received, the flat wire is U-shaped in the outer die until the inner die slides to a final position, the flat wire is propped against the outer die to enable the U-PIN to be completely formed in the width direction of the flat wire, the U-shaped end part needs to be greatly deformed in the final position, and the inner die is easy to rebound, so that the product forming is not facilitated.
2. The cost of the die is high. In the forming process, the flat copper wire needs to be pushed by the inner die for a long enough distance, so that the flat copper wire is ensured to be completely separated from the feeding frame, the flat copper wire can be integrally downward under the action of the pressing die, downward stripping is realized, and interference is avoided. Therefore, the existing inner die and the existing outer die are long, so that the die is heavy, and the die cost is increased.
3. The mold is damaged. In the forming process, the wire feet with paint removed are completely pushed into the space between the outer die and the inner die, so that the outer burrs of the wire feet with paint removed can be damaged. The mould after being damaged by the thread residue burrs can damage the paint skin of the subsequent products. And the mould is too long, can increase mould and flat copper line friction contact time, increase the damage risk.
Disclosure of Invention
In order to overcome the defects in the prior art, the embodiment of the utility model provides a flat wire stator U-PIN forming device, which is beneficial to product forming, avoids rebound of an inner die, shortens the lengths of an outer die and the inner die, ensures that wire feet are positioned outside the die in the U-PIN forming process, prevents the wire feet from damaging the die, reduces the weight of the die, and reduces the die generating cost.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a flat wire stator U-PIN molding device, the molding device comprising: the feeding frame is arranged on the base, the outer die and the inner die are connected to the base in a sliding manner, and the connecting rod mechanism is connected with the outer die; the inner die can push the flat wire positioned on the feeding frame into the outer die and push the outer die to slide together until the flat wire is positioned at a forming position; and the connecting rod mechanism applies gradually smaller resistance to the outer die in the sliding process of the outer die deviating from the feeding frame.
The U-PIN comprises a bending part formed by bending and stamping the middle part of the flat copper wire, two wire feet formed at two ends of the flat copper wire, and a rod part for connecting the bending part and the wire feet. The bending part comprises a first bending angle positioned at the top and a second bending angle positioned between the bending part and the rod part.
The outer die is connected to the base in a sliding manner, and the connecting rod mechanism connected with the outer die is arranged, so that when the inner die pushes the flat wire into the outer die, the connecting rod mechanism applies a resistance to the outer die, and the resistance gradually becomes smaller along with the depth of the flat wire into the outer die. That is, when the flat wire is initially formed, the resistance is the greatest, the flat wire is more attached to the top of the inner die, and the included angle formed by the top is more prone to the first bending angle in the final state. When the flat wire is finally formed, the resistance is minimum, the rebound of the inner die is avoided, and the final forming of the first bending angle is facilitated.
Further, the connecting rod mechanism comprises an air cylinder, a first sliding seat which is connected with a telescopic rod of the air cylinder and slides along the direction vertical to the base, a second sliding seat which is connected with a first sliding seat of the outer mold and slides along the extending direction of the base, and a connecting rod hinged between the first sliding seat and the second sliding seat.

And because the depth H1 of the forming notch of the outer die and the length H2 of the inner die are smaller than the length L of the U-PIN in the forming state, when the outer die and the inner die are in the die closing state, the wire feet of the flat wire are in a suspended state and are not pushed into the space between the outer die and the inner die, and the outer burrs of the wire feet and the paint removed skin cannot be damaged. Because the lengths of the outer die and the inner die are shortened, the weight of the die can be reduced, and the cost of the die is reduced.
Further, the device also comprises a pressing mold, wherein the pressing mold is opposite to the forming position; when the pressing die, the outer die and the inner die are in a die closing state, the pressing die and the inner die enable flat wires to be formed on two sides in the thickness direction of the flat wires. The pressing die is connected with a lifting mechanism on the base, and the lifting mechanism drives the pressing die to move towards or away from the base.
In the utility model, the mode of the outer die and the inner die is a mode that the inner die pushes the flat wire to a forming position to prop against the outer die.
