Description
Technical Field
[0001] This utility model relates to the field of stamping technology, specifically a stamping device for transformer housings. Background Technology
[0002] A transformer casing stamping device is a mechanical device used to produce transformer casings. It is mainly used to process metal sheets into the required shape and size through stamping.

[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This utility model discloses a transformer shell stamping device. When it is necessary to adjust the spacing of the openings, the controller controls the second motor to rotate, which drives the lead screw to rotate. Since the slide plate near the second motor meshes with the lead screw, when the lead screw rotates, it will drive the slide plate near the second motor to move. When this slide plate moves, it will drive the other slide plates to move at equal distances through two first connecting rods and four second connecting rods, thereby driving several stamping heads to move closer or further apart, thus realizing the adjustment of the spacing of several stamping heads, that is, adjusting the stamping spacing of several heat dissipation holes on the surface of the transformer shell, improving the flexibility and practicality of this device.
[0018] 2. The transformer shell stamping device of this utility model can control two electric telescopic rods to move forward through the controller before stamping the transformer shell. The two electric telescopic rods drive the brush plate to clean the dust and metal debris on the surface of the transformer shell, preventing the dust and metal debris from resisting the stamping. On the one hand, it can ensure the smooth progress of the stamping work and protect the stamping head. On the other hand, it can prevent damage to the transformer shell caused by the resistance of the two and improve the product quality.
[0019] 3. The transformer shell stamping device of this utility model uses a controller to control the fixing mechanism to position the transformer shell, preventing the transformer shell from being out of the center when it is placed, which would affect the stamping position of the transformer shell, that is, affect the forming position of several heat dissipation holes on the transformer shell, causing stamping failure of the transformer shell, reducing the scrap rate and avoiding economic losses.

[0029] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0030] The present invention provides the following preferred embodiments:
[0031] Example 1, as Figures 1-8 As shown, a transformer housing stamping device includes a base plate 1, a mounting frame 20, a worktable 2, and also includes a fixing mechanism, a die-casting mechanism, and a cleaning mechanism. The mounting frame 20 is fixedly installed above the base plate 1, and the worktable 2 is installed on one side of the mounting frame 20.
[0032] The fixing mechanism includes a horizontal plate 16, two clamping plates 3, a rotating assembly and two sliding assemblies. The horizontal plate 16 is located below the worktable 2. Both sliding assemblies are slidably mounted on the horizontal plate 16. Each clamping plate 3 is mounted on a sliding assembly.
[0033] The die-casting mechanism includes multiple stamping grooves 7, several stamping heads 6, lifting components and pitch-changing components, each of which has a stamping groove 7 located above the worktable 2;
[0034] The cleaning mechanism includes a brush plate 8 and a pushing assembly, with the pushing assembly located on one side of the mounting bracket 20 and the brush plate 8 located on the other side of the pushing assembly.
[0035] like Figures 1-8 As shown, the rotating assembly includes a first motor 9, a rotating rod 10, a U-shaped frame 11, and two hinge rods 12. The U-shaped frame 11 is fixedly mounted on the bottom surface of the workbench 2, the first motor 9 is fixedly mounted on the bottom surface of the U-shaped frame 11, the rotating rod 10 is rotatably mounted above the U-shaped frame 11, and the middle part of the rotating rod 10 is fixedly connected to the output end of the first motor 9. Each hinge rod 12 is rotatably connected to the rotating rod 10.
[0036] When it is necessary to stamp the transformer shell, the controller first controls the fixing mechanism to position the transformer shell to prevent the transformer shell from not being in the center when it is placed, which would affect the stamping of the transformer shell. The controller controls the first motor 9 to rotate, which drives the rotating rod 10 to rotate, thereby driving the two hinge rods 12 to rotate, which in turn drives the sliding component to move, and drives the two clamping plates 3 to position the transformer shell.
[0037] like Figures 1-8 As shown, each sliding assembly includes a slider 13, a groove 14, and a connecting plate 15. The slider 13 is rotatably disposed at one end of a hinge rod 12 away from the rotating rod 10. The horizontal plate 16 is fixedly disposed below the worktable 2. The groove 14 is fixedly disposed on the top of the horizontal plate 16. The slider 13 is slidably disposed in the groove 14. The connecting plate 15 is interactively disposed on the top of the slider 13. The clamping plate 3 is fixedly disposed on one side of the connecting plate 15.
[0038] When the two hinge rods 12 rotate, they cause the two sliders 13 to slide inside the two grooves 14, thereby causing the two clamping plates 3 to clamp the transformer casing.
[0039] like Figures 1-8 As shown, the lifting assembly includes a cylinder 17, a fixed plate 18, a sliding plate 19, a pressure block 30, a pressure plate 31, multiple sliding rods 32, and multiple springs 33. The fixed plate 18 is fixedly mounted on one side of the mounting frame 20. The cylinder 17 is inserted into the top of the fixed plate 18. The sliding plate 19 is slidably mounted on the mounting frame 20 and is fixedly connected to the output end of the cylinder 17. The pressure block 30 is fixedly mounted on the bottom of the sliding plate 19. Each sliding rod 32 is slidably mounted on the pressure block 30 and the sliding plate 19. On 9, each spring 33 is sleeved on a sliding rod 32, and the two ends of each spring 33 are fixedly connected to the top of the sliding rod 32 and the top of the sliding plate 19, respectively. It should be noted that in the initial state, the pressure plate 31 will move downward under the action of gravity, and at the same time, it will drive the sliding rod 32 downward. At this time, the height of the pressure plate 31 is lower than the height of the punch head 6, and the spring 33 is compressed. When the pressure block 30 descends and fits against the pressure plate 31, the height of the punch head 6 is lower than the height of the pressure plate 31.
[0040] When it is necessary to stamp the transformer shell, the controller controls the output of cylinder 17 to drive the pressure block 30 to slide downward. When the pressure block 30 moves downward, it will drive the pressure plate 31 to descend through spring 33 and sliding rod 32. When the pressure plate 31 contacts the transformer shell, it will fix the transformer shell first. At this time, the pressure block 30 returns to the chassis and continues to descend, driving multiple stamping heads 6 to descend. When the chassis of multiple stamping heads 6 descends, multiple stamping heads 6 will pass through the transformer shell and enter the stamping groove 7 to stamp and open holes in the transformer shell.
[0041] like Figures 1-8 As shown, the pitch-changing assembly includes a lead screw 22, a second motor 23, a mounting plate 28, two fixed blocks 29, two first connecting rods 24, five sliding plates 25, four second connecting rods 26, and two guide rods 27. The lead screw 22 is rotatably mounted between the two fixed blocks 29, which are respectively fixedly mounted on the pressure block 30. The mounting plate 28 is fixedly mounted on one of the fixed blocks 29. The second motor 23 is fixedly mounted on the outer wall of one of the fixed blocks 29, and its output end is fixedly connected to one end of the lead screw 22. Two guide rods 27 are fixedly mounted between the two fixed blocks 29, and each sliding plate 25 slides on the outer wall of the two guide rods 27. One of the slide plates 25 near the second motor 23 is threadedly connected to the lead screw 22. The lead screw 22 passes through several other slide plates 25. Four second connecting rods 26 are respectively hinged to the top of four of the slide plates 25. One of the first connecting rods 24 is hinged to the top of one of the slide plates 25 near the second motor 23. The end of one of the first connecting rods 24 away from the slide plate 25 is hinged to one of the second connecting rods 26. Another first connecting rod 24 is hinged to the mounting plate 28. The end of another first connecting rod 24 away from the mounting plate 28 is hinged to one of the second connecting rods 26. The bottom of each slide plate 25 is fixedly connected to several stamping heads 6.
[0042] When a change in spacing beyond the opening is required, the controller controls the second motor 23 to rotate, which in turn drives the lead screw 22 to rotate. Since the slide plate 25 near the second motor 23 meshes with the lead screw 22, when the lead screw 22 rotates, it will drive the slide plate 25 near the second motor 23 to move. When this slide plate 25 moves, it will drive the other slide plates 25 to move at equal distances through the first connecting rod 24 and the second connecting rod 26, thereby adjusting the spacing of the heat dissipation holes included in the transformer shell, that is, adjusting the stamping spacing of several heat dissipation holes on the surface of the transformer shell, thus improving the flexibility and practicality of the device.
[0043] like Figures 1-8 As shown, the pushing assembly includes two baffles 34 and two electric telescopic rods 35. Each baffle 34 is fixedly mounted on the top of the mounting frame 20, and each electric telescopic rod 35 is fixedly mounted on one side of a baffle 34. The output end of each electric telescopic rod 35 is fixedly connected to the brush plate 8.
[0044] Before stamping the transformer casing, the controller can control the output of two electric telescopic rods 35. The two electric telescopic rods 35 drive the brush plate 8 to move forward. The brush plate 8 cleans the surface of the transformer casing to prevent dust and metal debris from causing resistance to the stamping process. On the one hand, this ensures that the stamping work is carried out smoothly and protects the stamping head 6. On the other hand, it prevents damage to the transformer casing caused by the contact between the two and improves product quality.
[0045] like Figures 1-8 As shown, a limit block is provided at the top of the sliding rod 32 to prevent the sliding rod 32 from sliding out.
