Magnetic clamp device

Abstract

The invention provides a magnetic force tongs device. The magnetic force tongs device comprises tong arms and tong heads which are respectively hinged pairwise, wherein the two tong heads are cake-shaped; thread heads are fixed to the circular faces of the outer sides of the tong heads in the vertical axial directions; magnetic force heads which can be rotated and advance and retreat are assembled on the thread heads; the magnetic force heads are cake-shaped; magnetic blocks which are arrayed in a circle are uniformly distributed in the magnetic force heads; the magnetic force surfaces of the magnetic blocks and the tongs planes of the tong heads are parallel; the different magnetism faces, which are provided with the magnetic blocks, of the two corresponding magnetic force heads are opposite. The magnetic force tongs device is mainly used for carrying out clamping operation on sheet-shaped objects; when the device clamps, the clamping force is constant by the magnetic force effect; meanwhile, the distance between the two magnetic force heads is adjusted, the magnitude of the clamping force is conveniently adjusted, and the objects cannot be easily damaged.

Description

technical field [0001] The invention relates to the technical field of hardware tools, in particular to a magnetic clamp device. Background technique [0002] Pliers are a living and production tool that we use daily and are often used in industry. Pliers are mainly used to clamp objects or parts to transport and store them, or to complete some inconvenient actions. In the process of using pliers to clamp objects, people need to press the two handles of the pliers with both hands or one hand, and in the process of this kind of pliers, people need to apply pressure to the pliers with their hands all the time. Operation, once the hand is fatigued and the clamping force is reduced, it is very likely to cause accidents or accidents due to the drop of the clamp parts. Especially in industrial production, people often use pliers to clamp some heavier sheet materials or parts. Clamping operations are more risky. And people's strength is not easy to accurately control when clampin...

In the process of using pliers to clamp objects, people need to press the two handles of the pliers with both hands or one hand, and in the process of this kind of pliers, people need to apply pressure to the pliers with their hands all the time. Operation, once the hand is fatigued and the clamping force is reduced, it is very likely to cause accidents or accidents due to the drop of the clamp parts. Especially in industrial production, people often use pliers to clamp some heavier sheet materials or parts. Clamping operations are more risky

Moreover, when people are clamping objects, the strength is not easy to accurately control, and it is easy to damage the objects.

[0003] In industrial production, thin plate materials are often used by people. Workers often have to carry these materials during production. Among them, there are often some metal burrs on the edges of metal sheet raw materials, which are easy to hurt hands. At the same time, larger thin plates Such raw materials are also inconvenient to take and carry
