[0001] The application belongs to the technical field of bus duct shell stamping forming, in particular to a multifunctional combined stamping forming tool and method for bus duct shell. BACKGROUND

[0002] The bus duct shell is a closed structure made of metal plates such as steel plates, aluminum plates or stainless steel plates, mainly used for supporting and protecting the internal bus system and ensuring electrical safety.

[0012] A method for multifunctional combined stamping forming of busbar trunking shell, using the multifunctional combined stamping forming tooling for busbar trunking shell as described in any one of claims 1 to 8, characterized by comprising the following steps:

[0013] Step 1: Use mounting bolts that match the diameter of the mounting holes to fix the support base plate, thereby achieving the fixed installation of the entire tooling;

[0014] Step 2: Select a suitable metal sheet, and then use an external conveying mechanism or robotic arm to place the metal sheet on top of the forming mold;

[0015] Step 3: Start the hydraulic rod to push the connecting frame downwards. The connecting frame drives the stamping seat downwards. The stamping seat moves down and presses the metal sheet into the inside of the forming mold, so that the metal sheet is stamped into the outer shell shape of the busbar channel.

[0016] Step 4: Start the dual-axis motor to drive the two drive shafts to rotate simultaneously. The drive shafts rotate inside the positioning seat to ensure better stability during rotation. At the same time, the drive shafts drive the first drive bevel gear to rotate, the first drive bevel gear drives the first transmission bevel gear to rotate, the first transmission bevel gear drives the threaded rod to rotate, the threaded rod drives the threaded sleeve to move downward, and the threaded sleeve drives the first positioning slide sleeve to slide outside the first positioning slide rod to ensure better stability during movement. At the same time, the threaded sleeve drives the connecting shaft to move downward, the connecting shaft drives the support bar to move, and the support bar pushes the movable bar to slide outside the positioning crossbar through the movable shaft. The movable bar drives the punch head to move, and the punch head moves through the punching groove to punch the inside of the side of the outer shell.

[0017] Step 5: Simultaneously, the drive shaft drives the second drive bevel gear to rotate, which in turn drives the second transmission bevel gear to rotate. The second transmission bevel gear drives the transmission shaft to rotate, which in turn drives the transmission gear to rotate. The rotation of the transmission gear, through the action of the transmission tooth groove, causes the shearing blade to move downward. The shearing blade causes the second positioning sleeve to slide downward on the outside of the second positioning slide rod, which can ensure better stability of the shearing blade during movement. At the same time, the downward movement of the shearing blade removes the excess parts at both ends of the stamped shell.

[0018] Step Six: After the stamping is completed, the dual-axis motor rotates in the opposite direction, which resets the punch head and shearing blade. At the same time, the hydraulic rod retracts, causing the stamping seat to move upward and reset. Then, the stamped busbar shell is output through an external conveying mechanism or robotic arm for subsequent processing operations.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1) During operation, the interaction of the set support base plate, mounting holes, control switches, forming molds, support columns, support seats, hydraulic rods, connecting frames and stamping forming components enables the stamping forming device for processing busbar trunking shells to perform multi-functional combined stamping forming operations, thereby improving processing efficiency.

[0021] 2) During operation, the interaction between the first positioning sleeve and the first positioning rod makes it easier for the threaded sleeve to move with better stability, thereby ensuring that the stamping forming assembly can perform punching operations stably.

[0022] 3) During operation, the positioning seat makes it easier for the drive shaft to achieve better stability during use, thereby ensuring that the stamping assembly can maintain stable power output;

[0023] 4) During operation, the interaction of the second positioning slide sleeve, the second positioning slide rod, and the limiting block enables the shearing blade to achieve better stability during movement, thereby ensuring that the stamping forming assembly can perform shearing operations stably.

[0038] Example 2, based on Example 1, provides a method for multi-functional combined stamping forming of a busbar trunking shell, comprising the following steps:

[0039] Step 1: Use mounting bolts that match the diameter of mounting hole 2 to fix the support base plate 1, thereby achieving the fixed installation of the overall tooling;

[0040] Step 2: Select a suitable metal sheet, and then use an external conveying mechanism or robotic arm to place the metal sheet on top of the forming mold 3;

[0041] Step 3: Start the hydraulic rod 7 to push the connecting frame 8 downward. The connecting frame 8 drives the stamping seat 10 downward. The stamping seat 10 moves down and presses the metal sheet into the inside of the forming mold 3, so that the metal sheet is stamped into the outer shell shape of the busbar channel.

[0042] Step 4: Start the dual-axis motor 23 to drive the two drive shafts 24 to rotate simultaneously. The drive shafts 24 rotate inside the positioning seat 27 to ensure better stability during rotation.

[0043] Step 5: Simultaneously, the drive shaft 24 drives the second drive bevel gear 28 to rotate, the second drive bevel gear 28 drives the second transmission bevel gear 29 to rotate, the second transmission bevel gear 29 drives the transmission shaft 30 to rotate, the transmission shaft 30 drives the transmission gear 31 to rotate, and the rotation of the transmission gear 31 drives the shearing blade 32 to move downward through the action of the transmission tooth groove 33. The shearing blade 32 drives the second positioning sleeve 34 to slide downward outside the second positioning slide rod 35, which can ensure that the shearing blade 32 achieves better stability when moving. At the same time, the downward movement of the shearing blade 32 cuts off the excess parts at both ends of the stamped shell.

[0044] Step 6: After the stamping is completed, the dual-axis motor 23 rotates in the opposite direction, causing the punch head 15 and the shearing blade 32 to reset. At the same time, the hydraulic rod 7 retracts, causing the stamping seat 10 to move upward and reset. Then, the stamped busbar shell is output through an external conveying mechanism or robotic arm for subsequent processing operations.
