Description

Technical Field

[0001] This application relates to the technical field of plate shears, and in particular to a fixing mechanism for a plate shear. Background Art

[0002] When cutting metal plates with a plate shear, a fixing mechanism is required to fix the plate on the shear table to prevent the vertical pressure between the blade and the plate from causing the plate to vibrate and shift during shearing. In the prior art, the plate is generally fixed by a pressing cylinder pushing a pressing plate downward, so that the pressing block fixes the plate, and then the blade is controlled to move downward to cut the plate. Although plates of different thicknesses can be fixed, when performing plate shearing work, multiple drive sources need to be controlled to work and cooperate, increasing the complexity and operation and maintenance costs of the equipment.

[0003] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

The lower end of the connecting rod sequentially passes through the pressing plate and the limiting plate in a movable manner. A pressing block is arranged at the lower end of the connecting rod, and an elastic element is arranged between the pressing block and the limiting plate.

[0012] Preferably, electric conveying roller groups are provided on both sides of the shearing table on the frame for driving the movement of the plate to realize the loading and unloading operations of the plate.

[0013] Preferably, a plurality of threaded rods are rotatably arranged on the limit plate, the upper ends of the threaded rods pass through the pressure plate and are threadedly connected to the pressure plate, and two adjacent limit plates are transmission-connected via a transmission component to achieve synchronous rotation of the threaded rods.

[0022] The following is combined with Figures 1-3 This application is described in further detail.

[0023] The present application embodiment discloses a shearing machine fixing mechanism. Figures 1-3A fixing mechanism of a shearing machine includes a frame 1, a shearing table 2 is installed on the frame 1, a shearing assembly 4 is installed above the shearing table 2 on the frame 1, the shearing assembly 4 includes a pressing plate 402 slidably installed on the frame 1, a fixing mechanism 5 is installed on the pressing plate 402, the fixing mechanism 5 includes an adjusting assembly 501 and a pressing assembly 502, the relative initial position of the pressing assembly 502 is adjusted by the adjusting assembly 501, and then the pressure of the pressing assembly 502 on the plate is changed, which can adapt to plates of different thicknesses.

[0024] Reference Figure 1 An electric conveying roller group 3 is installed on both sides of the shearing table 2 on the frame 1. The electric conveying roller group 3 is composed of a plurality of conveying rollers, a chain transmission unit, and a driving motor. The two adjacent conveying rollers are connected by a chain transmission unit. The driving motor works to make the conveying rollers rotate to convey the plate, thereby realizing the loading and unloading operation of the shearing machine.

[0025] Reference Figure 3 The shearing assembly 4 also includes a telescopic cylinder 401 installed on the frame 1. The movable end of the telescopic cylinder 401 is fixedly connected to the top of the pressing plate 402. A cutter 403 is installed at the lower end of the pressing plate 402. The pressing plate 402 is driven up and down by the telescopic cylinder 401 to move the cutter 403 to perform shearing operations on the plate. The telescopic cylinder 401 can be selected from a telescopic cylinder and a hydraulic cylinder as needed.

[0026] Reference Figure 1 The adjusting component 501 includes two limit plates 5011 slidably installed under the pressure plate 402, and two threaded rods 5012 are installed on the limit plates 5011 through bearings. The upper end threads of the two threaded rods 5012 penetrate the pressure plate 402, and the two limit plates 5011 are slidably arranged on both sides of the cutter 403 to avoid interference between the cutter 403 and the limit plates 5011 when the telescopic cylinder 401 is extended and retracted to perform the shearing operation. The two adjacent threaded rods 5012 are connected by a belt drive assembly 5013. The limit plates 5011 are moved up and down by twisting the threaded rods 5012 to adjust the initial position of the pressing assembly 502.

[0027] Reference Figure 3 The pressing assembly 502 includes a connecting rod 5021 installed on the limiting plate 5011, and a limiting sleeve is installed on the upper end of the connecting rod 5021. The lower end of the connecting rod 5021 moves through the pressing plate 402 and the limiting plate 5011 in sequence, and is fixedly connected with a pressing block 5022. The sliding sleeve on the connecting rod 5021 is provided with a spring 5023, and the upper and lower ends of the spring 5023 are respectively abutted against the limiting plate 5011 and the pressing block 5022. An anti-slip pad is installed at the bottom of the pressing block 5022 to ensure flexible contact between the plate and the pressing block 5022. The spring 5023 is compressed by moving the limiting plate 5011 downward, so that the pressing block 5022 applies pressure to the plate to fix the plate.

[0028] The implementation principle of a shearing machine fixing mechanism in the embodiment of the present application is:

[0029] Before starting work, it is first necessary to adjust the initial position of the fixing mechanism 5 according to the thickness of the plate to be sheared. By twisting the threaded rod 5012 in the adjustment assembly 501, the limit plate 5011 moves up and down due to the transmission connection between the limit plates 5011 through the belt transmission assembly 5013. The position relative to the pressing block 5022 changes, and the initial deformation of the spring 5023 is changed to form the pressure of the initial contact of different fixed plates to adapt to plates of different thicknesses. The plate to be sheared is placed on the shearing table 2 and transported to the specified position by the electric conveying roller group 3. At this time, the telescopic cylinder 401 is controlled to extend, so that the pressing plate 402 and the limit plate 5011 move downward, and the pressing block 5022 in the material pressing assembly 502 contacts the plate, which will apply pressure to the plate. Since the pressing block 5022 and the plate are in flexible contact through the spring 5023, it can be ensured that the plate will not be over-pressed or damaged while being subjected to uniform pressure. At the same time, the anti-skid pad at the bottom of the pressing block 5022 can increase the friction between the pressing block 5022 and the plate, further improving the stability of the fixation. The telescopic cylinder 401 continues to drive the pressing plate 402 to move downward, so that the cutter 403 can accurately cut the plate. Since the plate has been firmly fixed by the fixing mechanism 5, the cutter 403 will not be affected by the movement or shaking of the plate during the cutting process, thereby ensuring the shearing accuracy and stability. After the shearing is completed, the telescopic cylinder 401 drives the pressing plate 402 and the cutter 403 to move upward and return to the initial position. At this time, the electric conveying roller group 3 starts again to convey the sheared plate out and prepare to receive the next plate to be sheared. The operator can check the shearing quality and make necessary adjustments as needed.
