Description

Technical Field

[0001] This invention relates to the field of busbar trunking processing technology, specifically to an automatic punching and shearing machine for busbar trunking connecting bars. Background Technology

[0002] Busbar connecting bars are key conductive components used to connect different sections of busbars in power transmission systems. Their processing quality directly affects the safety and stability of the entire power transmission system. In the production process of connecting bars, punching (for bolt connection) and shearing (for fixed-length segmentation) are two core processes.

[0003] Currently, the traditional processing method for busbar connecting strips mostly adopts a split operation. First, a punch press or hydraulic press is used to punch holes in the connecting strip, and then a shearing machine or saw is used to cut it to a fixed length. Different specifications of connecting strips require mounting holes of different diameters. Traditional punching equipment requires frequent replacement of punch dies, which is not only time-consuming but also increases the cost of dies. For thicker or high-strength connecting strips, cold stamping can easily lead to material edge cracking, excessive burrs, or dimensional deformation, while also causing significant wear on the stamping dies.

[0023] The multi-stage hydraulic assembly 10 consists of multiple sets of annular cylinders 101, multiple sets of connecting rods 102, annular pistons 103, and inlet / outlet oil pipe heads 104. The annular cylinders 101 are multiple concentric annular tanks nested together. Each annular cylinder 101 has an annular piston 103 slidably installed inside. Each annular piston 103 is connected to multiple connecting rods 102. The bottom ends of all connecting rods 102 pass downward through the connecting plate 9 and are connected to the stamping assembly 11. The inlet / outlet oil pipe heads 104 are respectively located at the top and bottom of the annular cylinders 101 for the inlet and outlet of hydraulic oil. By controlling the oil inlet sequence and oil pressure of different annular cylinders 101, multi-stage, variable-force stamping action can be achieved.

[0024] The stamping assembly 11 includes multiple concentric punching heads 111. Each punching head 111 has an inner ring with a movable groove 112. A connecting bolt 113 is fixed on the adjacent outer ring punching head 111. The connecting bolt 113 extends into the movable groove 112 of the inner ring punching head 111. A traction spring 114 is connected between the top of the connecting bolt 113 and the top wall of the movable groove 112. A pressing head 115 is provided at the center. An infrared sensor 116 is installed at the bottom of the pressing head 115 to detect the accuracy of the stamping position.

The output shaft of the servo motor 123 is connected to the swing plate 124. The laser 125 is fixed on the swing plate 124, and a cooling fan 126 is provided above it. The optical path of the laser 125 passes through the modulation mirror group 127 and the scanning galvanometer 128 in sequence, which can quickly scan and preheat the area to be punched in the connecting row below.

[0026] The waste recycling assembly 13 is located on the inner top of the machine body 1, including a recycling frame 131, a rotating plate 132, a connecting shaft 133, and a supporting hydraulic cylinder 134. Multiple sets of supporting hydraulic cylinders 134 are fixed on the top of the inner wall of the machine body 1, and their output ends are connected to the side wall of the recycling frame 131 through the connecting shaft 133. The top of the recycling frame 131 is hinged with a rotating plate 132 that can be flipped downwards. A collection frame 14 is placed at the bottom of the inner wall of the machine body 1 below the recycling frame 131. A door panel 27 for removing the collection frame 14 is opened on the side of the machine body 1. The waste generated by punching falls into the recycling frame 131, and then the rotating plate 132 is opened, and the waste falls into the collection frame 14.

[0027] Two sets of polishing components 16 are arranged vertically and mounted on the connecting plate 15. Each set of polishing components 16 includes a sliding cover 161, a top plate 162, an adjusting hydraulic cylinder 163, a connector 164, a sealing cover 165, a circulating hydraulic cylinder 166, a piston plate 167, a sealing ring 168, and an internally filled abrasive paste, such as a fluid abrasive containing diamond powder. The sliding cover 161 is slidably mounted on one side of the connecting plate 15, the top plate 162 is fixed to the top of the sliding cover 161, and the adjusting hydraulic cylinder 163 is mounted on the top plate. On plate 162, its output end is connected to sealing cover 165 through connector 164. Circulating hydraulic cylinder 166 is installed at the top of sealing cover 165, and its output end extends into sealing cover 165 and is connected to piston plate 167. Sealing ring 168 is provided at the bottom of sealing cover 165 for fitting with the surface of connecting row to form a sealing cavity. Polishing component 16 located above is connected to moving kit 8 through towing rod 222 and can move synchronously with moving kit 8. Polishing component 16 located below is driven by linkage cylinder 18 fixed to the inner wall of machine body 1.

[0028] The transport component 17 includes an electric guide rail 171, a clamping cylinder 172, a clamping block 173, and an anti-slip layer 174. The electric guide rail 171 is installed inside the machine body 1, and the clamping cylinder 172 is fixed at its moving end. The output end of the clamping cylinder 172 is connected to the clamping block 173. The clamping surface of the clamping block 173 is provided with an anti-slip layer 174. A through hole is opened on the inner side of the top of the machine body 1 corresponding to the transport component 17. The clamping block 173 can pass through the through hole and extend to the top of the machine body 1 to clamp the connecting row.

[0029] An external controller 19 is provided on one side of the machine body 1 to coordinate and control the working sequence of all hydraulic, electric and laser components. A top cover 26 is also provided on the top of the machine body 1 to prevent dust and provide protection.

[0030] The number of annular cylinders 101 in the multi-stage hydraulic assembly 10 is the same as the number of corresponding punching heads 111. When punching connecting bars with different hole diameters or thicknesses, different levels of annular cylinders 101 can be activated by the external controller 19. When punching small holes, only the innermost annular cylinder 101 is activated to drive the innermost punching head 111 to move. When punching large holes, multiple annular cylinders 101 are activated at the same time to drive multiple punching heads 111 to press down synchronously. The traction spring 114 helps the punching head 111 to reset after punching is completed.

[0031] When the preheating component 12 is working, the telescopic rod 122 adjusts the laser 125 to a suitable height, the servo motor 123 drives the swing plate 124 to swing, and at the same time the scanning galvanometer 128 controls the laser beam to scan at high speed in the area to be punched according to the preset pattern, so that the local material is heated up quickly to above the ductile-brittle transition temperature, thereby reducing cracks and burrs during punching. The cooling fan 126 is used to cool the laser 125 itself.

[0032] Working principle: In use, the long material of the busbar connecting strip is first fed into the front of the machine body 1. The hydraulic push rods 23 in the front and rear pressing components drive the extrusion rollers 25 to press down, clamping the connecting strip and conveying it forward. At the same time, it plays a role in straightening and stress relief. When the connecting strip passes the shearing component 3, the external controller 19 controls the clamping cylinder 172 in the transport component 17 to drive the clamping block 173 to clamp the connecting strip according to the preset length. The connecting strip is then accurately delivered to the shearing position by the electric guide rail 171. Subsequently, the downward hydraulic cylinder 34 of the shearing component 3 pushes the shearing blade 33 down, which, in cooperation with the pad plate 5, cuts the connecting strip into segments of the required length. After the segments are cut, the transport component 17 continues to clamp the segments and move them to the stamping station. At this time, the moving kit 8, driven by the electric guide rail 7, moves the connecting plate 9 to above the position to be punched. The laser 125 of the preheating component 14 is activated. The scanning galvanometer 128 performs rapid laser preheating on the area to be punched, raising the local material temperature to reduce punching resistance. Subsequently, the multi-stage hydraulic assembly 10 selects and activates the corresponding level of the annular cylinder 101 according to the required hole size, driving the corresponding punching head 111 to punch downwards, completing the punching. The punched waste falls into the recycling box 131 and finally enters the collection box 14. After punching is completed, the polishing assembly 16 works. The moving kit 8 drives the upper polishing assembly 16 to move synchronously through the traction rod 222. At the same time, the linkage cylinder 18 drives the lower polishing assembly 16, so that the upper and lower sealing covers 165 fit against the two sides of the hole of the connecting strip. The circulating hydraulic cylinder 166 pushes the piston plate 167 to make the abrasive paste in the sealing cover 165 repeatedly pass through the hole, performing fluid polishing on the punched edge and removing burrs. Finally, the processed connecting strip is sent out of the machine by the transport assembly and can enter the next process.
