Description
Technical Field
The utility model relates to a bending die, in particular to a coil winding and bending die; belongs to mechanical processing technical equipment.
Background
In order to make the motor coil winding more fit with the tile-shaped magnetic steel on the stator or the rotor, the coil needs to be pressed into a tile-shaped structure after being wound. Currently, the method is generally completed by a simple mold in a manual mode. Not only is labor intensity large and efficiency low, but also coil positioning is determined by visual inspection of an operator, so that the bending amplitude is difficult to be kept consistent with the magnetic steel, and product quality is influenced.
Disclosure of Invention
The above-mentioned defect to prior art exists, the utility model aims at providing a coil winding bending die that simple structure, convenient to use, bending efficiency are high, the bending forming precision is good.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the hydraulic press comprises an upper die and a lower die, wherein the upper die is composed of two pressure heads fixed on a hydraulic press, the bottom surface of each pressure head is of a semi-cylindrical structure, and a kidney-shaped guide hole is formed in the center of each pressure head; the lower die is fixed on the base, two arc-shaped grooves which are in a semi-cylindrical structure and are matched with the shape of the bottom surface of the corresponding pressure head are arranged on the surface of the lower die, a kidney-shaped positioning hole is formed in the center of each arc-shaped groove, and two guide columns fixed on the base penetrate through the corresponding positioning holes and are matched with the corresponding guide holes.
The guide post is in a conical structure with a small upper part and a big lower part.
Compared with the prior art, the utility model discloses owing to adopted above-mentioned technical scheme, consequently have following advantage:
1) because the guide posts which respectively penetrate through the centers of the two arc-shaped grooves are arranged on the base, the inner rings of the coil windings can be used as positioning reference, so that the accurate positioning of the two coil windings can be realized, and the equal distance between the two coil windings is ensured.
2) The inner ring of the coil winding is used as a positioning reference, and the superposition of the bending center and the geometric center of the coil winding can be further ensured, so that the shape of the bent coil winding is consistent with that of the tile-shaped magnetic steel.
3) Because the hydraulic press is adopted for bending, the labor intensity is effectively reduced, the processing efficiency is greatly improved, the bending pressure can be kept consistent, and the defect of inconsistent bending amplitude caused by bending resilience can be effectively avoided.

In the figure: the device comprises a guide post 1, a pressure head 2, a lower die 3, a base 4, a coil winding 5, a hydraulic machine 6, an arc-shaped groove 7 and a guide hole 8.
Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-5: the utility model discloses an go up mould and lower mould. The upper die is composed of two pressing heads 2 fixedly arranged on a hydraulic press 6, the bottom surface of each pressing head 2 is in a semi-cylindrical structure, and a kidney-shaped guide hole 8 is formed in the center of each pressing head 2. The lower die 3 is fixed on the base 4 through screws (not shown in the figure), and two arc-shaped grooves 7 which are in a semi-cylindrical structure and are matched with the shape of the bottom surface of the corresponding pressure head 2 are arranged on the surface of the lower die 3; the central position of each arc-shaped groove 7 is provided with a kidney-shaped positioning hole (not marked in the figure), and two guide columns 1 fixed on the base 4 through screws (not marked in the figure) upwards penetrate through the corresponding positioning holes and are matched with the corresponding guide holes 8.
In order to facilitate the guide post 1 to be smoothly inserted into the guide hole 8, the guide post 1 adopts a tapered structure with a small top and a large bottom.
When in use, the coil winding 5 is sleeved on the two guide posts 1, and then the two pressure heads 2 are pushed to press downwards by the hydraulic machine 6 until the coil winding 5 is completely attached to the arc-shaped surface of the arc-shaped groove 7; and then the two pressing heads 2 are lifted by a hydraulic machine 6, and the coil winding 5 is taken out.
