Description

Technical Field

[0001] The utility model belongs to the technical field of motor stator processing, and in particular relates to a B-type insulating paper forming device for a flat wire motor. Background Art

[0002] The stator core and copper wire of the new energy flat wire motor need to be separated by insulating paper. The slots of the insulating paper are rectangular holes. Depending on the different winding methods of the copper wire, the cross-sectional shapes of the insulating paper can be O-type, S-type, B-type, etc.

[0003] At present, there are relatively mature semi-automatic or fully automatic forming solutions for O-type and S-type. Both S-type and O-type forming solutions have processes such as indentation, mold forming, mechanical forming, and cutting. However, due to the fundamental difference from the cross-section of B-type paper, the various structures of the device are not applicable. For B-type paper, because it has six bends that are constantly bent inward, manual forming solutions are often used, but this method is inefficient and the quality of the finished product is difficult to guarantee. At the same time, because the insulation paper has high hardness and toughness, although the marks are pre-pressed, it is still very difficult to bend it into a B-type. During the folding process, workers may be cut by the paper, and there is no guarantee in terms of efficiency, quality, safety, etc. Utility Model Content

An automatic power source 305 is provided on the other side of the indentation punch 302. A floating clamping mechanism is provided above the indentation punch 302.

[0044] The indentation convex die 302 and the indentation concave die 303 are arranged parallel to each other and relatively matched. A plurality of indentation convex rings are formed on the indentation convex die 302, and annular grooves matched with the indentation convex rings are formed on the indentation concave die 303.

[0045] Specifically, the punch seat 306 is provided with a vertically penetrating groove, in which the indentation punch 302 is placed. The indentation punch 302 penetrates the entire thickness of the punch seat 306 and extends outward beyond the boundary of the punch seat 306, which is used to fix and support the punch, ensuring that the indentation punch 302 does not move or deform during the working process; the punch seat 306 is also provided with a horizontally penetrating groove, in which the rotating shaft is placed and fixed at both ends of the punch seat 306, and at the same time, the rotating shaft also axially penetrates the indentation punch 302, which is used to drive the indentation punch under the driving device. The mold 302 rotates; a manual power source 304 is provided at one end of the punch seat 306, and the manual power source 304 is fixed to the rotating shaft extending from the end of the punch seat 306. The manual power source 304 can provide a rotating force for the rotating shaft, thereby driving the indentation punch 302 to rotate; an automatic power source 305 is provided at the other end of the punch seat 306, and the automatic power source 305 is fixed to the rotating shaft at the end of the punch seat 306 through a tightening sleeve 313. The automatic power source 305 can provide a rotating force for the rotating shaft, thereby driving the indentation punch 302 to rotate.

[0046] A first fixing groove 309 is formed at one end of the punch seat 306, and a first fixing plate 311 is arranged on the outer side of the first fixing groove 309.

The rotating shaft horizontally passes through the second fixing groove 310 and is fixed to the tightening sleeve 313 by a locking bolt, and then is fixed to the automatic power source 305 by the tightening sleeve 313.

[0047] The adapter sleeve 313 includes a sleeve head, a sleeve rod and a sleeve tail which are fixedly connected to each other. The sleeve head extends into the first fixing groove 310 and is fixedly connected to the rotating shaft through a locking bolt. The sleeve tail is engaged with the power shaft of the automatic power source 305, so that the adapter sleeve 313 is tightly fixed on the power shaft.

Sparks or heat may be generated during operation at this location. The protective plates can effectively block these potential dangerous factors and protect operators from injury. At the same time, it also reduces the risk of damage to the equipment due to accidental impact, and can also prevent dust, impurities and other particles from entering the interior of the equipment through the connection and affecting the normal operation of the device.

[0049] Preferably, the first fixing plate 311 is a rectangular plate, and the first protective plate 312 is an L-shaped plate.

[0050] Preferably, the manual power source 304 may be a manual crank, and the automatic power source 305 may be a motor.

[0051] like Figure 3 , Figure 4 As shown, two layers of floating plates are arranged above the punch seat 306, namely the first floating plate 307 and the second floating plate 308; a plurality of rotating screw rods are passed through the first floating plate 307, and a plurality of supporting columns are fixed between the first floating plate 307 and the punch seat 306; the second floating plate 308 is located between the first floating plate 307 and the punch seat 306, and is passed through by the supporting columns at the corresponding positions, and a spring is sleeved on the supporting columns between the second floating plate 308 and the punch seat 306, and the clamping force can be adjusted by rotating the screw rod. The second floating plate 308 is pressed downward toward the punch seat 306 by the pressing of the rotating screw rod, thereby reducing the distance between the indentation punch 302 and the indentation die 303, and increasing the indentation depth, and vice versa.

[0052] like Figure 4 As shown, several support columns are also fixed between the punch seat 306 and the mounting plate, and springs are sleeved on the support columns between the two; the positions and numbers of the support columns between the punch seat 306 and the mounting plate correspond to those between the first floating plate 307 and the punch seat 306; an indentation die 303 is fixed below the punch seat 306 and on the inner side of the support columns, and both ends of the indentation die 303 are fixed to the mounting plate through die supports.

[0053] A guide seat 301 mounted on a mounting plate is provided on the outer side of the indentation die 303. The height of the guide seat 301 is flush with the position of the indentation die 303, so as to guide the insulating paper transmitted by the guide plate to between the indentation die 303 and the indentation punch 302, and form an indentation by extrusion.

[0054] The indentation punch 302 is a cylindrical structure with six indentation convex rings formed on the side wall of the cylinder. The indentation die 303 is formed with an annular groove that cooperates with the indentation convex rings, so as to form the six marks required for bending. The insulating paper enters between the punch and the die through the guide seat 301, and the indentation is formed by extrusion. The indentation depth is adjusted by the floating clamping mechanism. The indented insulating paper flows into the primary cutting mechanism 4 through the shearing table 405.

[0056] By adopting the above technical solution, the insulating paper enters between the indentation die 303 and the indentation punch 302 through the guide seat 301, and the automatic power source 305 or the manual power source 304 can provide a rotating force for the rotating shaft, so that the indentation punch 302 rotates. As the indentation punch 302 rotates, its surface gradually contacts with the groove. When it rotates and contacts the indentation groove, the insulating paper begins to be pressed into the groove. When the indentation punch 302 rotates to a predetermined position and completes the indentation, it will continue to rotate and withdraw from the groove. During this period, the spring helps the punch to be smoothly pressed and withdrawn to avoid additional loss or deformation of the insulating paper; the clamping force can be adjusted by tightening or loosening the rotating screw rod on the first floating plate 307, and then the depth of the indentation can be adjusted; in the indentation mechanism 3, it is necessary to ensure that the positions of the punch and the die are accurately aligned to ensure the accuracy and consistency of the indentation.

[0059] The side surfaces of the shearing table 405 opposite to the first cutting edge guide plate 401 are respectively provided with engaging blocks 406, in which the first cutting edge guide plate 401 can be engaged, so as to limit the first cutting edge guide plate 401 and ensure the accuracy and consistency of cutting.

[0060] The shearing table 405 is installed on the mounting plate, and is used to fix the insulating material to be cut and the first lower blade 404; a support frame 407 is also fixed to the outside of the shearing table 405 on the mounting plate, which is fixed to the first cutting cylinder 402 to provide support force for the first cutting cylinder 402, and further provide support force for the primary cutting mechanism 4.

[0061] Preferably, the distance and relative position between the first upper blade 403 and the first lower blade 404 can be adjusted according to actual conditions to adapt to different materials and cutting requirements.

Under the action of the first blade guide plates 401 on both sides, the first upper blade 403 and the first lower blade 404 cooperate to cut the two sides of the insulating paper, leaving only the middle part still connected, completing the first cutting. After the first cutting, the insulating paper flows into the primary forming mechanism 5; when the insulating paper flows through the primary cutting mechanism for a certain length, the first cutting process is repeated, wherein the forward distance of the insulating paper is controlled by the servo motor, and cutting is performed after the set distance is reached.

[0073] It should be noted that the secondary cutting mechanism 7 is similar to the primary cutting mechanism 4, except that the second upper blade is different. The second upper blade is a flat blade. The same settings of the secondary cutting mechanism 7 will not be described here. This time, the shaped insulating paper will be completely cut.

[0074] By adopting the above technical solution, the shaped insulating paper continues to flow into the secondary cutting mechanism 7, and the cutting cylinder 701 pushes the second upper blade 703 to fall quickly. Under the action of the second blade guide plates 702 on both sides, the second upper blade 703 and the second lower blade 705 cooperate to completely cut the insulating paper, completing the second cutting.

[0075] Working principle of B-type insulation paper forming device:

[0076] The automatic power source or the manual power source drives the insulating paper to flow backward continuously. The feeding mechanism smoothly and accurately feeds the insulating paper from the material tray 201 and flows into the guide seat 301 of the indentation mechanism 3 through the coordinated setting of the material tray 201, the roller 204 and the guide seat 301. The insulating paper passes through the guide seat 301 and enters between the indentation die 303 and the indentation punch 302. Six indentations are formed by extrusion. At the same time, the indentation depth can be adjusted by the floating clamping mechanism; the insulating paper with indentations flows into the shearing table 405 of the primary cutting mechanism 4, and the cutting cylinder pushes the first upper blade 403 to fall quickly. Under the action of the first blade guide plates 401 on both sides, the first upper blade 403 and the first lower blade 404 cooperate to cut the two sides of the insulating paper, leaving only the middle part still connected, completing the first cutting. After the first cutting, the insulating paper flows into the opening of the feeding table 503 of the primary forming mechanism 5; it continues to flow into the release Placed on the support plate 501, the upper pressing block 509 presses the insulating paper on the support plate 501 under the action of the upper pressing cylinder 502, and the lower forming punches on both sides of the support plate 501 extend upward under the action of the lower forming cylinder to form the first group of bends of the insulating paper, and then the forming cylinders on both sides extend, and the forming punches on both sides fold the insulating paper into the third group of bends; after the two groups of bends are formed, the upper pressing cylinder 502 is depressurized and released, and the lower forming cylinder is retracted. Under the push of the automatic power source 305, the insulating paper continues to flow into the secondary molding mechanism 6; in the secondary molding mechanism 6, under the action of the spiral molding surface 605 on the first molding die 601 and the second molding die 603 and the guiding of the molding core 602, the second group of bends are squeezed and formed, and finally, under the action of the molding cover 604, the final shaping is carried out, and the finally shaped insulating paper continues to flow into the secondary cutting mechanism 7, and the secondary cutting mechanism completely cuts the shaped insulating paper to complete the shaping of type B insulating paper.

[0077] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
