Description
Technical Field
[0001] This utility model relates to the technical field of transformer cover plate bending devices, and in particular to a transformer cover plate bending device. Background Technology
[0002] A transformer cover plate bending device is a piece of equipment used to bend the sheet metal of a transformer cover plate according to specific angle and size requirements. In the transformer manufacturing process, the bending accuracy of the cover plate directly affects the transformer's sealing performance, safety, and overall appearance quality.
[0003] During the use of the current transformer cover bending device, staff often find that transformer covers often need to be bent into specific shapes. Currently, this usually relies on manual adjustment of the plate position, angle, and bending equipment parameters multiple times. Each adjustment takes a certain amount of time, resulting in a long processing cycle and reduced production efficiency of transformer covers. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a transformer cover plate bending device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a transformer cover plate bending device, comprising a machine base, a gantry frame fixedly connected to the machine base, a bending structure provided on the gantry frame, the bending structure mainly consisting of a first cylinder, the first cylinder fixedly connected to the gantry frame, a bending block fixedly connected to the piston rod of the first cylinder, a sliding plate slidably connected to the bending block, a sliding block slidably connected to the machine base, rotating blocks rotatably connected to both sides of the sliding block, a receiving groove provided on the rotating block, and a first roller rotatably connected to the receiving groove.
[0006] The effect achieved by the above components is as follows: the cover plate is placed on the sliding block, the first cylinder is activated, and the piston rod of the first cylinder drives the bending block to descend. After the sliding plate contacts the plate, the sliding plate presses on top of the plate. As the bending block continues to descend, it presses on both sides of the plate, causing it to bend inward. After bending, as the bending block continues to descend, it pushes the sliding block to slide downward. At this time, the first roller slides along the machine table, driving the rotating block to rotate, further bending the initially bent plate outward, so that the plate is formed into the required shape in one go. There is no need for the staff to constantly change the position of the plate, thus avoiding the current situation where the plate position, angle, and bending equipment parameters are usually adjusted manually multiple times, and each adjustment takes a certain amount of time, resulting in a long processing cycle and reduced production efficiency of transformer cover plates.
[0007] Preferably, two sliding grooves are respectively formed on the inner walls of both sides of the bending block, and the sliding grooves slide with the sliding plate.
[0008] The effect achieved by the above components is that the sliding plate slides within the groove, making the sliding process more stable.
[0009] Preferably, two first springs are fixedly connected in the machine tool, and one end of the first spring is fixedly connected to the sliding block.
[0010] The effect achieved by the above components is as follows: during the downward movement of the sliding block, the two first springs will be compressed and contracted. After the bending is completed, the bending block drives the sliding plate to rise, and the sliding block slides upward and resets under the action of the rebound force of the two first springs, which facilitates the next bending operation.
[0011] Preferably, a second spring is fixedly connected in the groove, and one end of the second spring is fixedly connected to the sliding plate.
[0012] The effect achieved by the above components is that as the sliding plate rises along the slide groove, it will compress the second spring to contract. Therefore, after the bending block rises, the sliding plate will move downward and reset under the action of the rebound force of the second spring.
[0013] Preferably, the machine base is provided with a limiting structure, which mainly consists of two second cylinders. Both second cylinders are fixedly connected to the machine base. A slide rail is fixedly connected to the piston rod of the second cylinder. Two limiting blocks are slidably connected in the slide rail. Several second rollers are rotatably connected to the limiting blocks.
[0014] The effect achieved by the above components is as follows: the two limiting blocks slide according to the size of the plate. After the plate is placed, the second cylinder is activated. The piston rod of the second cylinder drives the slide to rise. The two limiting blocks guide the plate so that the plate is in the middle position. The second roller can make the rising process of the limiting blocks smoother.
[0015] Preferably, two slide rods are fixedly connected to the slide rail, and the slide rods are slidably inserted into the machine base.
[0016] The effect achieved by the above components is that the two slide bars slide at the upper limit of the machine, making the movement of the slide more stable.
[0017] Preferably, a bidirectional screw is rotatably connected to the slide rail via a bearing, the two sections of the bidirectional screw have opposite thread directions, and the bidirectional screw is threadedly connected to two limiting blocks.
[0018] The effect achieved by the above components is that rotating the bidirectional screw can drive the two limit blocks to slide synchronously in opposite directions.
[0019] Preferably, a motor is fixedly connected to the slide rail, and the bidirectional screw is driven to rotate by the motor.
[0020] The effect achieved by the above components is as follows: the output end of the motor is connected to the bidirectional screw through the reducer and coupling. The model of the motor is 17HS4401. First, the power is turned on to power the motor control system, and then the motor is started to drive the bidirectional screw to rotate.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting a bending structure, the cover plate is placed on the sliding block. The first cylinder is activated, and the piston rod of the first cylinder drives the bending block to descend. After the sliding plate contacts the plate, the sliding plate presses on the plate. As the bending block continues to descend, it presses on both sides of the plate, causing it to bend inward. After bending, as the bending block continues to descend, it pushes the sliding block to slide downward. At this time, the first roller slides along the machine table, driving the rotating block to rotate, further bending the initially bent plate outward. Thus, the plate is formed into the required shape in one go, eliminating the need for workers to constantly change the plate position. This avoids the current situation where the plate position, angle, and bending equipment parameters are usually adjusted manually multiple times, each adjustment taking a certain amount of time, resulting in a long processing cycle and reduced production efficiency of transformer cover plates.

[0027] Example 1, such as Figure 1 As shown, a transformer cover plate bending device includes a machine base 1, on which a gantry frame 2 is fixedly connected.
[0028] Reference Figures 2 to 3 A bending structure 3 is installed on the gantry frame 2. The bending structure 3 mainly consists of a first cylinder 31, which is fixedly connected to the gantry frame 2. A bending block 32 is fixedly connected to the piston rod of the first cylinder 31. A sliding plate 33 is slidably connected to the bending block 32. A sliding block 34 is slidably connected to the machine base 1. Rotating blocks 35 are rotatably connected to both sides of the sliding block 34. A receiving groove 36 is opened on the rotating block 35. A first roller 37 is rotatably connected to the receiving groove 36. The cover plate is placed on the sliding block 34, and the first cylinder 31 is started. The piston rod of cylinder 31 drives the bending block 32 to descend. After the sliding plate 33 contacts the sheet metal, the sliding plate 33 presses down on the sheet metal. As the bending block 32 continues to descend, it presses down on both sides of the sheet metal, causing it to bend inward. After bending, as the bending block 32 continues to descend, it pushes the sliding block 34 to slide downward. At this time, the first roller 37 slides along the machine base 1, driving the rotating block 35 to rotate, further bending the initially bent sheet metal outward, thus forming the sheet metal into the required shape in one go. This eliminates the need for workers to constantly change the position of the sheet metal, thereby avoiding the current... Typically, manual adjustments to the plate position, angle, and bending equipment parameters are required multiple times, each adjustment taking time and resulting in a long processing cycle, which reduces the production efficiency of transformer cover plates. Two grooves 39 are respectively opened on the inner walls of both sides of the bending block 32. The grooves 39 slide with the sliding plate 33, and the sliding plate 33 slides within the grooves 39, making the sliding process more stable. Two first springs 38 are fixedly connected in the machine base 1, with one end of each spring fixedly connected to the sliding block 34. During the downward movement of the sliding block 34, it will squeeze... When the two first springs 38 are compressed and the bending is completed, the bending block 32 drives the sliding plate 33 to rise. Then, the sliding block 34 slides upward and resets under the action of the rebound force of the two first springs 38, which facilitates the next bending operation. A second spring 310 is fixedly connected in the slide groove 39. One end of the second spring 310 is fixedly connected to the sliding plate 33. As the sliding plate 33 rises along the slide groove 39, it will compress the second spring 310 and compress it. Therefore, after the bending block 32 rises, the sliding plate 33 moves downward and resets under the action of the rebound force of the second spring 310.
[0029] Reference Figure 4The machine base 1 is equipped with a limit structure 4, which mainly consists of two second cylinders 41. Both second cylinders 41 are fixedly connected to the machine base 1. A slide rail 42 is fixedly connected to the piston rod of each second cylinder 41. Two limit blocks 43 are slidably connected in the slide rail 42. Several second rollers 44 are rotatably connected to each limit block 43. The two limit blocks 43 slide according to the size of the sheet material. After the sheet material is placed, the second cylinders 41 are activated. The piston rods of the second cylinders 41 drive the slide rail 42 to rise, and the two limit blocks 43 guide the sheet material, placing it in the middle position. The second rollers 44 make the rising process of the limit blocks 43 smoother. Two sliding rods 47 are fixedly connected to the slide rail 42. The slide is inserted into the machine base 1. Two slide rods 47 slide at the upper limit of the machine base 1, making the movement of the slide rail 42 more stable. A bidirectional screw 45 is rotatably connected to the slide rail 42 through a bearing. The two sections of the bidirectional screw 45 have opposite threads. The bidirectional screw 45 is threadedly connected to two limit blocks 43. Rotating the bidirectional screw 45 can drive the two limit blocks 43 to slide synchronously in opposite directions. A motor 46 is fixedly connected to the slide rail 42. The bidirectional screw 45 is driven to rotate by the motor 46. The output end of the motor 46 is connected to the bidirectional screw 45 through a reducer and a coupling. The model of the motor 46 is 17HS4401. First, the power is turned on to power the control system of the motor 46. Then, the motor 46 is started to drive the bidirectional screw 45 to rotate.
[0030] Working principle: The cover plate is placed on the sliding block 34. The first cylinder 31 is activated, and its piston rod drives the bending block 32 to descend. After the sliding plate 33 contacts the plate, it presses down on top of the plate. As the bending block 32 continues to descend, it presses down on both sides of the plate, causing it to bend inward. After bending, as the bending block 32 continues to descend, it pushes the sliding block 34 downward. At this time, the first roller 37 slides along the machine base 1, driving the rotating block 35 to rotate, further bending the initially bent plate outward. This allows the sheet material to be formed into the desired shape in one step, eliminating the need for workers to constantly change the sheet material's position. This avoids the current situation where multiple manual adjustments to the sheet material's position, angle, and bending equipment parameters are required, each adjustment taking time and resulting in a long processing cycle and reduced production efficiency for transformer cover plates. The sliding plate 33 slides within the slide groove 39, making the sliding process more stable. As the sliding block 34 moves downward, it compresses the two first springs 38 to contract. After bending is complete, the bending block 32 drives the sliding plate 33 to rise, and the sliding block 34 slides upward to reset under the rebound force of the two first springs 38, facilitating the next bending operation. As the sliding plate 33 rises along the slide groove 39, it compresses the second spring 310 to contract. Therefore, after the bending block 32 rises, the sliding plate 33 moves downward to reset under the rebound force of the second spring 310. The two limiting blocks 43 slide according to the size of the sheet material. After the sheet material is placed, the second cylinder 41 is activated. The piston rod of the second cylinder 41 drives the slide rail 42 to rise, and the two limiting blocks 43... The plate is guided to be in the middle position. The second roller 44 makes the rising process of the limit block 43 smoother. The two slide rods 47 slide at the upper limit of the machine base 1, making the movement of the slide rail 42 more stable. Rotating the bidirectional screw 45 can drive the two limit blocks 43 to slide synchronously in opposite directions. The output end of the motor 46 is connected to the bidirectional screw 45 through a reducer and a coupling. The model of the motor 46 is 17HS4401. First, the power is turned on to power the control system of the motor 46. Then, the motor 46 is started to drive the bidirectional screw 45 to rotate.
