Description

Technical Field

[0001] This utility model relates to a metal cutting device, and more particularly to a high-precision, high-speed synchronous shearing device. Background Technology

[0002] In the production of copper rods / copper bars, continuous casting is generally used. However, copper rods / copper bars produced by continuous casting are often irregularly curved. This means that the newly produced copper rods / copper bars need to be straightened, and after straightening, they are continuously cut to a fixed length to ensure uniform factory dimensions.

[0003] Since the copper rod / busbar is still in constant motion during cutting, the shearing blade usually needs to move synchronously with the copper rod / busbar to ensure cutting accuracy. Currently, a common method is to clamp the copper rod / busbar with a cylinder, using friction to drive the shearing blade and achieve synchronous cutting, as shown in CN219074553U and CN112024771B. However, this method requires the copper busbar to drive the cutting, which can easily damage the copper rod / busbar during clamping, resulting in poor surface quality. Utility Model Content

[0044] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] For example, to cut copper busbars, please refer to [link / reference]. Figures 1 to 3 As shown, the high-precision, high-speed synchronous shearing device includes a base 1, a shearing table 2, a synchronous frame 3, a guide frame 4, a metering mechanism, a drive mechanism 5, a synchronous slide rail 6, a shearing mechanism 7, a reset mechanism 8, and a controller. The shearing table 2 is fixed to the base 1. The synchronous frame 3, guide frame 4, metering mechanism, drive mechanism 5, synchronous slide rail 6, and reset mechanism 8 are all fixed to the shearing table 2. The shearing mechanism 7 is slidably mounted on the synchronous slide rail 6. Specifically:

[0046] The synchronous frame 3 is arranged parallel to one side of the synchronous slide rail 6, and two pulleys 31 are provided on it, with a synchronous belt 32 wound between the two pulleys 31.

[0047] The guide frame 4 is provided with several guide rollers for driving the copper busbar 9 to move. The meter counting mechanism is located at the front end of the guide frame 4. The meter counting mechanism includes a meter counting wheel and an encoder.

[0048] The drive mechanism 5 includes a drive motor and a transmission assembly. The drive motor drives one of the guide rollers and one of the pulleys 31 to rotate through the transmission assembly, and the guide rollers and pulleys 31 have the same linear velocity.

[0049] The shearing mechanism 7 includes a slider 71, which is slidably mounted on the synchronous slide rail 6. The slider 71 is provided with a shearing bracket 72 and a clamping bracket. The shearing bracket 72 is provided with a shearing assembly. The clamping bracket is located on the side of the slider 71 close to the synchronous frame 3, and is provided with a clamping assembly for clamping the synchronous belt 32.

[0050] The reset mechanism 8 includes a reset slide rail 81 and a reset cylinder 82, and the reset cylinder 82 and the slider 71 are both slidably disposed on the reset slide rail 81.

[0051] The encoder, drive motor, shearing assembly, clamping assembly, and reset cylinder 82 are all electrically connected to the controller.

[0052] With the above technical solution, when the metering mechanism detects that the feed length of the copper busbar 9 has reached the set value, the controller controls the clamping mechanism to clamp the synchronous belt 32. At this time, the synchronous belt 32 will drive the slider 71 to move forward synchronously. Then the controller controls the shearing component to shear the copper busbar 9. At this time, the shearing component and the copper busbar 9 remain relatively stationary. After the shearing is completed, the clamping mechanism releases the synchronous belt 32, and then the reset cylinder 82 pushes the slider 71 back to the initial position, waiting for the next shearing.

[0053] It is worth mentioning that, such as Figure 3 The clamping assembly includes an upper clamping plate 75 and a lower clamping plate 76. A clamping cylinder 77 is provided on the top of the upper clamping plate 75. The telescopic rod of the clamping cylinder 77 passes through the upper clamping plate 75 and is connected to the clamping block 78. A synchronous belt 32 with the same running direction as the copper busbar 9 passes between the clamping block 78 and the lower clamping plate 76. The clamping cylinder 77 is electrically connected to the controller.

[0054] With the above technical solution, when it is necessary to clamp the synchronous belt 32, the controller controls the clamping cylinder 77 to move the clamping block 78 downward, clamping the synchronous belt 32 between the clamping block 78 and the lower clamping plate 76. This solution uses the clamping cylinder 77 for control, which has a short response time and effectively improves the shearing accuracy.

[0055] Understandably, the shearing assembly is similar to existing structures, including a hydraulic cylinder 73, which is mounted on top of the shearing bracket 72 and electrically connected to the controller. A shearing blade 74 is fixedly connected to the end of its telescopic rod at its bottom. Upon receiving a signal from the controller, the hydraulic cylinder 73 drives the shearing blade 74 downwards, thus shearing the copper busbar 9.

[0056] Furthermore, the reset cylinder 82 is a rodless cylinder to provide higher precision and speed; the drive motor adopts torque mode, which can maintain synchronous output even after the synchronous belt 32 is clamped by the clamping mechanism.

[0057] It is worth mentioning that, such as Figure 3 The reset mechanism 8 also includes a positioning component, which is disposed between the reset slide rail 81 and the guide frame 4. The positioning component includes a buffer block and a proximity sensor. The proximity sensor is electrically connected to the controller and is used to detect the position of the slider 71 so as to stop the movement of the reset cylinder 82 when the slider 71 reaches the origin position. The buffer block prevents the slider 71 from colliding when it stops.

[0058] It is understandable that, such as Figure 2 The base 1 is provided with an adjusting slide rail 11 and an adjusting cylinder 12. The shearing table 2 is slidably mounted on the adjusting slide rail 11, and the telescopic rod of the adjusting cylinder 12 is hinged to the bottom of the shearing table 2.

[0059] The guide rollers on the guide frame 4 include several free rollers, one active roller, and at least one pressure roller. The active roller is connected to a drive motor via a transmission assembly, and the pressure roller is mounted on the telescopic rod of a cylinder and positioned directly above the active roller. During shearing, the cylinder controls the pressure roller to move downwards, clamping the copper busbar 9 with the active roller. The drive motor is connected to the active roller via a coupling, driving it to rotate, thereby feeding the copper busbar 9.

[0060] It should be added that the drive motor is connected to one of the pulleys 31 via gears to facilitate adjustment of the rotational speed of the pulley 31, thereby ensuring that the linear speeds of the guide roller and the pulley 31 are the same. If the rotation direction of the pulley 31 is opposite to that of the drive roller, the clamping assembly clamps the lower synchronous belt 32; if the rotation direction of the pulley 31 is the same as that of the drive roller, the clamping assembly clamps the upper synchronous belt 32, thus ensuring that the movement direction of the clamping assembly after clamping the synchronous belt 32 is consistent with that of the copper busbar.

[0061] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
