Description

Technical Field

[0001] This utility model relates to the field of hydraulic swing beam shearing machines, specifically a plate positioning mechanism for a hydraulic swing beam shearing machine. Background Technology

[0002] Hydraulic swing beam shearing machines are widely used in the field of metal sheet processing. During operation, the main oil cylinder (fixed on the wall panel) performs downward shearing motion, while the nitrogen cylinder returns. During operation, the pressurized oil pushes the cylinder plunger downward to move the blade holder downward for shearing, while simultaneously compressing the nitrogen in the cylinder. During the return stroke, the hydraulic system is unloaded, and the nitrogen in the cylinder expands to cause the blade holder to return. The entire blade holder performs a reciprocating swing motion around the support shaft to complete the shearing work. It is suitable for industries such as automobile manufacturing and steel structure manufacturing that have high requirements for shearing speed and production efficiency.

[0003] Existing hydraulic swing beam shearing machines have certain limitations in plate positioning. Specifically, current positioning mechanisms often cannot adapt flexibly and accurately to plates of different thicknesses and sizes, especially when the plate thickness varies greatly. The original positioning reference may become inapplicable, forcing the operator to readjust, which not only increases the complexity of operation but also prolongs production time, thereby increasing time and labor costs. To address this, we propose a plate positioning mechanism for hydraulic swing beam shearing machines. Utility Model Content

[0013] 2. The plate positioning mechanism of this hydraulic swing beam shearing machine uses a motor to drive the lead screw to rotate, which, together with the sliding groove limit, allows the clamping box to move flexibly and easily adjust the C-shaped vertical plate spacing. It can be adapted to the actual width and length of the plate at any time. Whether the plate is narrow or wide, short or long, the positioning adjustment can be completed quickly without the need to replace a large number of parts or tools. This saves preparation time, meets diverse production needs, and enhances the versatility of the equipment in different processing scenarios. Attached Figure Description

[0026] Working principle: When shearing sheet metal, motor 2 is started first according to the width of the sheet metal. Motor 2 drives the lead screw 3 to rotate. When the lead screw 3 rotates, the slider 5 slides on the lead screw 3 due to the limiting of the connecting block 17 by the slide groove 15. The slider 5 drives the C-shaped vertical plate 8 of the clamping box 6 to move towards the fixed side of the clamping box 6 through the connecting block 17. At the same time, the bearing seat 4 follows the movement of the clamping box 6 and keeps the slide groove 15 closed. When the spacing between the C-shaped vertical plates 8 is convenient for clamping the sheet metal, the sheet metal is placed between the four electromagnetic plates 12 and the C-shaped vertical plates 8. The first cutting line of the sheet metal is aligned with the blade of the hydraulic swing plate shearing machine. The electromagnetic plates 12 on the raised platform 7 are energized by the control component 13. The electromagnetic plates 12 are magnetically connected to the C-shaped vertical plates 8 to clamp the sheet metal. The electromagnetic plates 12 and the C-shaped vertical plates 8 tightly clamp the sheet metal. The piston rod of the double-cylinder hydraulic cylinder 19 is activated to extend and retract. When the main body of the double-cylinder hydraulic cylinder 19 moves, it drives the C-shaped vertical plates 8. Adjust the spacing between the C-shaped vertical plates 8 according to the maximum length of the sheet material. After adjustment, control component 13 controls the electromagnetic plate 12 on the clamping box 6 to be energized. The energized electromagnetic plate 12 magnetically connects with the C-shaped vertical plate 8 to clamp the sheet material. The electromagnetic plate 12 and the C-shaped vertical plate 8 tightly clamp the sheet material at four positions, and the hydraulic swing beam shearing machine can be started to cut the sheet material. After the first cut is completed, first release the electromagnetic plate 12 and the C-shaped vertical plate 8 on the raised platform 7. Start the piston rod extension and retraction movement of the double-cylinder hydraulic cylinder 19 to move the C-shaped vertical plate 8 on the clamping box 6 to the raised platform 7 until the second cut line is parallel to the blade of the hydraulic swing beam shearing machine. Clamp the C-shaped vertical plate 8 and the electromagnetic plate 12 on the raised platform 7 and start the hydraulic swing beam shearing machine to cut. Repeat this process until the sheet material is cut. Each time the electromagnetic plate 12 is de-energized, the rebound force of the spring 10 pulls the electromagnetic plate 12 and the telescopic rod 11 to move between the sleeve 9, thereby releasing the sheet material.
