Description

Technical Field

[0001] This utility model belongs to the field of busbar trunking production technology, specifically relating to a punching mechanism for busbar trunking production. Background Technology

[0002] Busbar trunking is a closed-type conductive device used for power transmission and distribution, mainly composed of a metal casing, conductive bars, insulating materials, and accessories. During operation, busbar trunking generates heat, especially under high current conditions, where conductor resistance loss significantly increases temperature. Therefore, openings are made in the side plates of the busbar trunking casing to create natural convection channels, promote airflow, accelerate heat dissipation, and reduce the overall temperature of the busbar trunking. These openings also facilitate equipment connection and are therefore commonly found in the side plates of the busbar trunking.

[0003] In the prior art, a busbar trunking punching device is usually used for punching. For example, the utility model with patent publication number CN215966432U discloses a punching device for busbar trunking production and processing. The device includes a table, with four sets of support devices connected to the lower end of the table. The table has a first sliding groove, and a threaded rod is rotatably connected to the first sliding groove. The threaded rod passes through the table and is connected to a rocking device. Two sets of symmetrical threaded sleeves are connected to the outer wall of the threaded rod inside the first sliding groove. The threaded sleeves are connected to a first slider, and the first slider is connected to a first clamping plate. The first clamping plate is slidably connected to a second clamping plate. The busbar trunking body is placed on the outer side of the first clamping plate and the second clamping plate respectively. Two sets of symmetrical drilling devices are placed on the side end of the busbar trunking body. The drilling devices are slidably connected to a slide frame, and the slide frame is rotatably connected to two sets of symmetrical rotating frames.

[0004] The aforementioned utility model features symmetrical drilling devices on both sides of the busbar trunking, allowing for separate drilling. Compared to traditional twist drills, this avoids deformation and increases the hole diameter. Furthermore, the clamp uses a threaded rod to drive two symmetrical clamping plates, ensuring a secure clamping action and simplifying operation, thus improving efficiency. However, this device lacks flexibility, still requiring manual adjustment of the busbar trunking side plates to change the drilling position, resulting in low automation. Therefore, a highly automated punching mechanism for busbar trunking production, eliminating the need for manual adjustment of the side plate positions, is required. Utility Model Content

In use, the operator places the side plate on a workbench, with both ends of the side plate contacting the two workbenches respectively, while the middle of the side plate contacts the support plate. A limiting groove restricts the side plate, positioning it. Then, the control system activates the first linear movement structure, which moves the support seat closer to one end of the side plate. The control system then activates the second linear movement structure, which moves the punch downwards to punch a hole in the side plate. After passing through the side plate and entering the circular groove, the punch returns to its original position, completing the hole in one area of ​​the side plate. The first linear movement structure then moves the support seat a certain distance towards another workbench, and the second linear movement structure and punch are then controlled to punch another portion of the side plate, repeating this process.

[0030] Work style:

[0031] In use, the operator places the side plate on the workbench 11, with both ends of the busbar trunking side plate contacting the two workbench 11s respectively, while the middle of the busbar trunking side plate contacts the support plate 24. The limiting groove 17 restricts the busbar trunking side plate, positioning it. Then, through the control system, the first linear movement structure 12 is activated, which moves the support seat 21 closer to one end of the busbar trunking side plate. Subsequently, the control system controls the second linear movement structure 22 to activate, which moves the punch 23 downward to punch a hole in the busbar trunking side plate. After passing through the busbar trunking side plate and entering the circular groove, the punch 23 returns to its original position, completing the opening of one area of ​​the busbar trunking side plate. Then, the first linear movement structure 12 moves the support seat 21 a certain distance towards the other workbench 11, and the second linear movement structure 22 and the punch 23 are controlled to punch another part of the busbar trunking side plate. This process is repeated, eliminating the need for manual adjustment of the position of the busbar trunking side plate, and enabling punching of multiple areas of the busbar trunking side plate with a high degree of automation.

[0032] like Figures 1 to 3 As shown, preferably, the bottom of the support base 21 has a hollow structure; a through slot is provided in the middle of the support base 21 so that the circular groove on the support plate 24 is connected to the bottom of the support base 21; after the punch 23 punches the busbar side plate, the waste material falls from the circular groove to the bottom of the support base 21.

[0035] like Figures 2 to 4As shown, the difference from Embodiment 1 is that: a structural form of the protrusion 15 is given; the punching assembly 2 also includes a pressure rod 25; the punch 23 is connected to the second linear moving structure 22 through the pressure rod 25; one end of the pressure rod 25 is connected to the movable end of the second linear moving structure 22, and the other end is connected to the end of the punch 23 away from the support plate 24. The pressure rod 25 increases the range of motion of the second linear moving structure 22, thereby reducing the range of motion of the second linear moving structure 22.

[0036] like Figures 2 to 4 As shown, preferably, the punching assembly 2 further includes a pressure seat 26; the pressure seat 26 is connected to the end of the pressure rod 25 away from the second linear movement structure 22; the punch 23 passes through the pressure seat 26 toward the support plate 24; optionally, a limiting slide rail is vertically provided in the middle of the support base 21, the pressure seat 26 is slidably connected to the limiting slide rail, and slides up and down along the limiting slide rail to limit the sliding direction of the pressure seat 26; the side of the pressure seat 26 away from the pressure rod 25 is a horizontal plane; the punching assembly 2 further includes a pressure plate 27 and a spring 28; one end of the spring 28 is connected to the side of the pressure seat 26 away from the pressure rod 25, and the other end is connected to the plate surface of the pressure plate 27; The side of the pressure plate 27 away from the pressure rod 25 is horizontal; the punch 23 passes through the pressure plate 27 and faces the support plate 24; initially, there is a gap between the pressure plate 27 and the support plate 24. When punching, the busbar side plate is placed in the gap between the pressure plate 27 and the support plate 24. The second linear moving structure 22 extends and drives the pressure rod 25 to move downward. The pressure seat 26, the pressure plate 27 and the punch 23 will all move downward together. The pressure plate 27 first contacts the busbar side plate, presses down the busbar side plate to prevent the busbar side plate from tilting up and keep the busbar side plate flat. Then the punch 23 passes through the pressure plate 27 and punches the busbar side plate.
