Description

Technical Field

[0001] The present invention relates to the field of hardware tools, and particularly to a handle bending device for wire cutters. Background Art

[0002] Hardware, traditional hardware products, are also called "small hardware". It refers to five metals: gold, silver, copper, iron, and tin. Through manual processing, they can be made into artworks such as knives and swords or metal devices. Hardware in modern society is more extensive, such as hardware tools, hardware components, daily hardware, building hardware, and security supplies, etc. Most small hardware products are not final consumer goods.

[0003] Bending refers to the process in which a metal sheet is under the pressure of the upper die or lower die of a bending machine. First, it undergoes elastic deformation, and then enters plastic deformation. At the beginning stage of plastic bending, the sheet is freely bent. As the upper die or lower die presses on the sheet, the sheet gradually presses against the inner surface of the V-shaped groove of the lower die. At the same time, the radius of curvature and the bending moment arm also gradually become smaller. Continue to apply pressure until the stroke ends, so that the upper and lower dies and the sheet are in full contact at three points. At this time, a V-shaped bend is completed, which is commonly known as bending.

[0004] Pliers are a kind of manual tool used for clamping, fixing workpieces, or twisting, bending, and cutting metal wires. The pliers are in a V shape, usually including a handle, a jaw, and a nose. The handle part of the pliers is formed by bending.

[0005] The existing bending devices have the disadvantage of low bending efficiency. Therefore, it is necessary to design a handle rapid bending device for hardware manufacturing with rapid bending. Summary of the Invention

[0034] Batch processing of wire cutters. The wire cutters fall from the feeding port into the chute and are held by the first stop block. Then, when the motor is started, the second stop block lifts the rear of the wire cutters in front, so that the wire cutters at the back are held against the second stop block, and the wire cutters are fed in batches in pairs.

[0035] Push the wire cutters, start the first screw motor, drive the push-down plate to move, push the wire cutters onto the triangular block, make the wire cutters fork, then start the second telescopic cylinder, push the top block out, lift the pliers head of the wire cutters, start the second screw motor again, drive the push-up plate to move right, push the lifted pliers head to the right, make the wire cutters detach from the triangular block, and send the wire cutters onto the positioning block under the transmission of the fourth conveyor belt, finally insert the steel plate, and squeeze the handle of the wire cutters under the action of the first pressing plate and the second pressing plate to complete the bending.

[0036] Preferably, the first telescopic cylinder is started, the first telescopic cylinder pushes the push rod to move, the push rod meshes with the pinion gear for transmission, so that the baffle is flipped out, and a small and narrow channel is formed after the baffle is flipped out, so that the inclined wire cutters can be guided through.

[0037] Preferably, under the transmission of the first transmission belt, the driving gear and the driven gear rotate, and the driving half gear and the driven half gear mesh to drive the connecting plate to move up and down, so that the lifting plate moves up and down to drive the wire cutters with the handle facing forward to flip over, and under the drive of the second transmission belt, the wire cutters fall smoothly from the discharge port.

[0038] Preferably, the motor drives the first toothed disc and the second toothed disc to rotate, causing the first rotating handle to touch the right side of the first balance rod, pressing down the left side of the first balance rod on the first hook member, prompting the first abutting block to move downward, and the wire cutters in front to fall out. Then, after the first rotating handle rotates past, it disengages from the first balance rod, causing the first abutting block to bounce back under the action of the first spring. At this time, the second rotating handle touches the left side of the second balance rod, pressing down the right side of the second balance rod on the second hook member, prompting the second abutting block to move downward, causing the wire cutters after the disaster to slide in front of the first abutting block, and repeating this step.

[0039] Preferably, after passing through the chute, the wire cutters fall onto the third conveyor belt. The third conveyor belt drives the wire cutters to move leftward, causing the wire cutters to enter the partition block. The lower push plate pushes the wire cutters to move rightward and enter the diverter plate under the guidance of the partition block. The lower push plate pushes rightward and slowly presses down the diverter plate, causing the lower push plate to continue to push the wire cutters to the triangular block.
