DETAILED DESCRIPTION

[0015] The accompanying drawing shows an embodiment of the present utility model.

[0016] The utility model discloses a demoulding device for a resin cast transformer winding, comprising a support frame platform 1, on which a row of conveying rollers 2 are installed for conveying cast transformer windings 7 with molds; a horizontal guide rod 6 is fixed on the left and right sides of the middle of the support frame platform, on which a vertical upright pole 5 is slidably installed, and a horizontal pressing plate is installed on the upright pole for pressing the transformer windings.

[0017] The vertical pole has threads from top to bottom, and a nut 14 is screwed on the vertical pole thread. The nut is welded and fixed to the pressing plate 9, and the pressing plate is used to insert into the gap between the transformer winding 7 and the casting mold 3; the vertical pole 5 and the nut are used to rotate the pressing plate 9 up and down to adjust it to the same height as the transformer winding.

[0018] A vertical pole 5 is slidably mounted on the guide rail rod, a slider 13 is welded to the lower end of the pole, and a middle hole of the slider is sleeved on the guide rail rod 6.

[0019] The bottom surface of the casting mold 3 is a plane, on which a plurality of lifting noses 4 are welded, which are used to lift the mold by a crane for demoulding. After demoulding, the winding is transported to the tail of the platform by a conveying roller and then moved away.

[0020] A fixed base plate 8 is welded to the lower end of each leg of the support frame platform 1, and the fixed base plate is fixed to the ground by embedded bolts.

[0021] The guide rails 6 on both sides of the support frame platform adopt square guide rails to prevent the pull rods from tipping over.

[0022] The resin casting winding demoulding device is provided with a transmission platform with rollers, a full-thread pull rod is fixed on a guide rail which can be moved left and right, and a pressure plate is arranged on the top for karaoke winding.

[0023] The starting end, middle end and tail end of the upper edge of the support frame platform are respectively installed with a starting photoelectric switch 11, a middle photoelectric switch 12 and a terminal photoelectric switch 10, which are used to detect whether the transformer winding is coming over, thereby starting or closing the conveying roller 2.

[0024] The conveying roller is an existing product, including a row of rollers installed on a frame via bearings, a gear is installed at the end of each roller, and the gears are meshed in sequence. The first roller or the last roller is connected to the motor through a pulley pair or a sprocket pair.

[0025] When in use, the operator measures the height of the transformer winding, rotates the pressing plate 9 along the tie rod 5 to reach this height, and then moves the pressing plate outward to a position that does not interfere with the transformer winding 7. Use a crane or a crane to place the cast and hardened transformer winding with a mold on the drive roller 2 of the support frame platform 1. The photoelectric switch 11 at the beginning detects the transformer winding. After the drive roller is started, it moves forward with the transformer winding. After moving to the middle of the two guide rods, the middle photoelectric switch 12 detects the transformer winding, and the drive roller stops running. The operator manually pushes the two tie rods 5 along the guide rod 6 to a suitable position close to the transformer winding. The operator moves the pressing plate so that the two pressing plates 9 are stuck in the gap between the casting mold 3 and the transformer winding 7. The operator operates the crane. The operator hangs the nose 4 of the casting mold plane with a wire rope and a hook. The crane pulls the nose upward and shakes it gently, and the casting mold is smoothly pulled upward out, completing the demoulding task of the winding. The operator moves the pressing plate so that the two pressing plates 9 are moved to a position that does not interfere with the transformer winding. Start the transmission roller 2, which carries the transformer winding forward to the tail of the support frame platform. After the end photoelectric switch 10 senses the transformer winding, the transmission roller stops running, and the transformer winding is moved away by workers and mechanical devices.

[0026] Practice has proved that the resin casting winding demoulding device has changed the previous working conditions of smashing, prying and jacking. In the past, smashing and prying would cause problems such as broken and damaged winding surface that affect the appearance. This solution adopts a transmission platform with rollers, on which a full-wire pull rod that can move left and right is provided, so that the winding can be stably fixed on the transmission platform. The mold can be demoulded by just using a crane and lifting the mold, which is convenient and fast, and does not damage the winding. If this device is combined with an assembly line platform, continuous operation can be achieved, greatly improving production efficiency.
