Description

Technical Field

[0001] This utility model belongs to the field of bending devices, specifically, it relates to a rectifier bridge pin bending device. Background Technology

[0002] Before bending, the pins of a rectifier bridge are usually straight. To facilitate the insertion and use of the rectifier bridge, the pins need to be bent at a 90-degree angle.

[0003] Chinese Patent No. CN213530566U discloses a rectifier bridge pin bending device. Paragraph 31 of the specification discloses that a small hydraulic cylinder is controlled to move a telescopic rod downward, which drives the cross platform, the bending frame and the pressure plate of the bending mechanism to move downward. When the telescopic rod moves downward, the pressure plate closes with the first placement groove through the third placement groove, thereby covering the rectifier bridge and fixing the connection between the rectifier bridge and the pin from top to bottom, preventing the connection between the pin and the rectifier bridge from being damaged by excessive pressure during the bending process.

[0004] However, in the aforementioned rectifier bridge pin bending device, a small hydraulic cylinder drives multiple pressure plates to slide down and squeeze the pins to bend. The small hydraulic cylinder is located at one end of the horizontal platform, and the force on the side away from the horizontal platform gradually decreases from the end closer to the small hydraulic cylinder to the end farther away from the small hydraulic cylinder, resulting in a large pressure difference between the pressure plates, which affects the bending effect on the rectifier bridge pins.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Please see Figure 1-3 As shown, this embodiment provides a rectifier bridge pin bending device, including:

[0030] Operating table 1, with a placement platform 101 on the upper side of the operating table 1;

[0031] The stamping mechanism 2 includes a support frame 201 disposed on the upper side of the operating table 1, a plurality of rack stamping parts 202 vertically slidably fitted on the support frame 201, a gear assembly 203 rotatably fitted inside the support frame 201 and meshing with the plurality of rack stamping parts 202, a first rack 204 slidably fitted on one side of the support frame 201 and meshing with the gear assembly 203, and a cylinder 205 disposed on the upper side of the operating table 1 for driving the first rack 204 to slide.

[0032] By placing the rectifier bridge on the placement platform 101 and activating the stamping mechanism 2, the cylinder 205 drives the first rack 204 to slide. The first rack 204 meshes with the gear assembly 203, causing the gear assembly 203 to rotate. The gear assembly 203 meshes with multiple rack stamping parts 202, causing the rack stamping parts 202 to slide down and stamp the rectifier bridge pins. This facilitates the improvement of the uniformity of force on the multiple rack stamping parts 202, reduces the difference in force on the rectifier bridge pins, and improves the bending effect of the rectifier bridge pins.

[0033] Please see Figure 1-3 As shown, the support frame 201 in this embodiment has a U-shaped frame structure. Two support protrusions 206 are provided at the bottom of the support frame 201 to facilitate support of the support frame 201. The rack stamping part 202 includes a second rack 2021 vertically slidably fitted on the support frame 201, and a pressure plate 2022 elastically slidably fitted at the bottom of the second rack 2021. A guide groove 2023 is provided at the bottom of the second rack 2021, and a sliding contact is slidably fitted within the guide groove 2023. The moving bar 2024 and the sliding bar 2024 are provided with springs 2025 on the upper side and the top surface of the inner wall of the guide groove 2023. The pressure plate 2022 is fixed to the bottom end of the sliding bar 2024, so that it can mesh with the second rack 2021 of the multiple rack stamping parts 202 through the gear assembly 203, and drive the pressure plate 2022 to slide down to stamp the rectifier bridge pins. This can improve the uniformity of the force on the multiple rack stamping parts 202, reduce the difference in force on the rectifier bridge pins, and improve the bending effect of the rectifier bridge pins.

[0034] Please see Figure 1-2 As shown, the support frame 201 of this embodiment has a cross-shaped guide hole 207 on its upper side corresponding to the second rack 2021. The second rack 2021 is a cross-shaped strip structure. The second rack 2021 is fixedly and slidably fitted in the cross-shaped guide hole 207, which facilitates the sliding of the second rack 2021 through the cross-shaped guide hole 207 and improves the stability of the sliding of the second rack 2021.

[0035] Please see Figure 1-3 As shown, the gear assembly 203 in this embodiment includes a drive shaft 2031 rotatably fitted within a support frame 201, a first gear 2032 disposed at one end of the drive shaft 2031 extending out of the support frame 201, and a second gear 2033 fixedly sleeved on the drive shaft 2031 and meshing with a second rack 2021. The first gear 2032 meshes with the first rack 204, facilitating the sliding of the first rack 204 via a cylinder 205. The first rack 204 meshes with the first gear 2032, driving the drive shaft 2031 and multiple second gears 2033 to rotate.

[0036] Please see Figure 1-2 As shown, the support frame 201 of this embodiment is provided with a T-shaped slide rail 208 on the upper side, and a T-shaped protrusion 209 is provided at one end of the first rack 204. The T-shaped protrusion 209 is slidably fitted in the T-shaped slide rail 208 and fixed on the output end of the cylinder 205, so as to facilitate the sliding of the T-shaped protrusion 209 through the T-shaped slide rail 208 and improve the sliding stability of the first rack 204.

[0037] Please see Figure 1-3As shown, the placement platform 101 of this embodiment is provided with a plurality of placement slots 102, and the plurality of placement slots 102 correspond one-to-one with a plurality of pressure plates 2022. By placing the rectifier bridge in the placement slot 102, the pins of the rectifier bridge extend out of the placement slot 102, which facilitates the stamping of the pins of the rectifier bridge.

[0038] Working principle: The rectifier bridge is placed in the placement slot 102, so that the pins extend out of the placement slot 102. The stamping mechanism 2 is activated, and the cylinder 205 drives the first rack 204 to slide. The first rack 204 meshes with the first gear 2032, which drives the transmission shaft 2031 and multiple second gears 2033 to rotate. The second gears 2033 mesh with the second rack 2021, which drives the pressure plate 2022 to slide down and stamp the rectifier bridge pins. By setting the pressure plate 2022 to buffer through the sliding strip 2024 and the spring 2025, the probability of instantaneous pressure damaging the rectifier bridge is reduced.
