Technical Field

[0001] The utility model relates to the technical field of transformer component processing, in particular to a plate bending device for transformer component processing. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the outer shell, primary coil, secondary coil and iron core. The main functions of a transformer are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. During the transformer production process, the staff needs to use a sheet bending device to bend the sheets constituting the transformer parts. For example, a sheet bending machine proposed in the publication number "CN208067022U" includes a frame, a bending device, a base, and a bending mold, which is characterized in that: the frame includes an upper support plate, a lower support plate, a column, and a cross plate, and the two columns are symmetrically arranged on the upper support plate. A card slot is arranged inside the base, and the lower end of the bending mold is arranged inside the card slot. Support rods 1 are symmetrically arranged on both sides of the base, and a buffer spring is sleeved on the support rods 1. The bending device includes a cylinder, a pressure block, and a pressure plate. A hollow support rod 2 is arranged at the lower end of the pressure plate, and the cylinder is connected to the pressure block. A cushion block is arranged on the upper support plate, and a tension spring is arranged inside the cushion block. Support plates are symmetrically arranged on both sides of the cushion block, and a fixed plate is arranged on the support plate.

DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 4As shown, a plate bending device for processing transformer parts comprises a workbench 1, a first gantry 2 is fixedly mounted on the upper surface of the workbench 1, a cylinder 3 is fixedly mounted on the middle of the upper surface of the first gantry 2, an output end of the cylinder 3 passes through the first gantry 2 and is fixedly mounted with a lifting plate 4, a pressing die 5 is fixedly mounted on the lower surface of the lifting plate 4, and a forming die 6 is fixedly mounted on the upper surface of the workbench 1;

[0025] The bottom of the forming mold 6 is provided with a mounting groove 7, and the lower end of the mounting groove 7 passes through the workbench 1;

[0026] A second gantry 8 is fixedly installed on the lower surface of the workbench 1, and a motor 9 is fixedly installed on the lower surface of the second gantry 8. The output shaft end of the motor 9 passes through the second gantry 8 and is fixedly installed with a screw rod 10. A movable plate 11 is threadedly provided on one side of the screw rod 10. Support rods 1101 are fixedly installed on both sides of the upper surface of the movable plate 11, and a top plate 12 is fixedly installed on the upper surfaces of the two support rods 1101.

[0027] A vertical pole 13 is fixedly installed at the inner bottom of the second gantry 8 , and the movable plate 11 is slidably arranged on one side of the pole body of the vertical pole 13 .

[0028] The staff places the sheet on the surface of the forming die 6, and then starts the cylinder 3, so that its output end drives the lifting plate 4 to descend, so that the die 5 presses the sheet into the interior of the forming die 6. After the sheet is bent and formed, the staff controls the lifting plate 4 to move to its original position, and then starts the motor 9, so that its output shaft end drives the screw 10 to rotate. The rotating screw 10 drives the movable plate 11 to move along the direction of the vertical rod 13 by screwing in the thread, so that the top plate 12 lifts the sheet and the sheet is detached from the inside of the forming die 6. The staff does not need to manually take the sheet out of the forming die 6, which significantly improves the production efficiency and avoids the staff from being injured when taking out the sheet.

[0029] In another embodiment of the utility model, a cavity 1201 is opened inside the top plate 12, a connecting plate 14 is movably arranged in the cavity 1201, and a plurality of connecting columns 15 are fixedly installed on the upper surface of the connecting plate 14;

[0030] A plurality of through holes 16 are formed through the top surface of the cavity 1201 . The upper end surface of each connecting column 15 extends to the inside of the corresponding through hole 16 and is formed with a spherical groove. A rolling ball 17 is rotatably installed in each spherical groove.

[0031] Telescopic rods 18 are provided on both sides of the bottom of the cavity 1201, and the connecting plate 14 is fixedly installed on the movable ends of the two telescopic rods 18;

[0032] An electric push rod 19 is fixedly installed in the middle of the bottom of the cavity 1201 , and the output end of the electric push rod 19 is fixedly connected to the connecting plate 14 .

[0033] After the top plate 12 lifts the sheet and the sheet is separated from the forming die 6, the staff starts the electric push rod 19 so that its output end drives the connecting plate 14 to rise, so that the rolling ball 17 passes through the through hole 16 and lifts the sheet. When the staff pulls the sheet to separate it from the top plate 12, the sliding friction between the lower surface of the sheet and the upper surface of the top plate 12 is converted into rolling friction under the rolling action of the rolling ball 17, which greatly reduces the wear on the surface of the sheet and also saves the staff more physical strength.

[0034] In another embodiment of the present invention, the upper surface of the connecting plate 14 is flush with the inner bottom surface of the forming mold 6 .

[0035] When the connecting plate 14 is in the initial position, the upper surface of the connecting plate 14 is flush with the inner bottom surface of the forming die 6 so that the upper surface of the connecting plate 14 can support the plate pressed into the forming die 6 to prevent the plate from being squeezed and deformed by the die 5 due to lack of support.

[0036] In another embodiment of the present invention, a triangular plate 20 is fixedly mounted on one side of the forming die 6 .

[0037] By setting the triangular plate 20, after the rolling ball 17 lifts the plate, the staff can move the plate to the position of the triangular plate 20. The inclined surface of the triangular plate 20 can guide the plate, making it convenient for the staff to move the formed plate to the surface of the workbench 1, and then store the plate in the storage position.

[0038] The working principle of this plate bending device for transformer parts processing:

[0039] When in use, the staff places the plate on the surface of the forming mold 6, and then starts the cylinder 3, so that its output end drives the lifting plate 4 to descend, so that the pressing die 5 presses the plate into the interior of the forming mold 6. After the plate is bent and formed, the staff controls the lifting plate 4 to move to its original position, and then starts the motor 9, so that its output shaft end drives the screw rod 10 to rotate, and the rotating screw rod 10 drives the movable plate 11 to move along the direction of the vertical rod 13 by screwing in the thread, so that the top plate 12 lifts the plate, so that the plate is detached from the inside of the forming mold 6. The staff does not need to manually take the plate out of the forming mold 6, which significantly improves the production efficiency and avoids the staff from being injured when taking out the plate.

[0040] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
