The profitable effect of utility model is: the utility model discloses it is rational in infrastructure, can reach the effect that is similar to the shearing through linear motion, effect of cutting is good, and the mountable is used for the cutting of multiple materials such as cloth, area material, paper stock in the automation equipment.

Description

a cutting device

technical field

The utility model relates to a cutting device, in particular to a cutting device with an oblique design.

Background technique

The existing cutting device often has a parallel relationship between the upper and lower blades, and when cutting some materials with better toughness, it is often not easy to cut.

Contents of the invention

The utility model aims to solve the above-mentioned shortcomings of the prior art, and provides a cutting device with good cutting effect.

The technical scheme adopted by the utility model to solve its technical problems: this cutting device includes an upper cutter and a lower cutter, the upper cutter is provided with an upper cutter edge, the lower cutter is provided with a lower cutter edge, and the lower cutter position is Fixed, the edge of the lower cutter is parallel to the horizontal position, an acute angle is formed between the edge of the upper cutter and the edge of the lower cutter, the upper cutter can move up and down and when it moves downward, the edge of the upper cutter and the edge of the lower cutter form a stagger.

Preferably, the upper cutter is provided with downward extensions on both sides of the edge of the upper cutter to prevent the cut material from moving left and right to leave the position.

Preferably, the acute angle is less than 30 degrees to ensure better cutting effect.

As a preference, position adjustment bolts are provided on the upper cutter and the lower cutter to prevent their front and rear positions from loosening and thereby reducing the cutting effect.

Preferably, the upper cutter is connected with a cylinder as its power device.

The beneficial effects of the utility model are: the utility model has a reasonable structure, can achieve the effect similar to shearing through linear motion, has a good cutting effect, and can be installed on automatic equipment for cutting various materials such as cloth, tape, and paper. .

detailed description

Below in conjunction with accompanying drawing, the utility model is further described:

Embodiment: as Fig. 1, a kind of cutting device comprises upper cutter 1 and following cutter 2, the bottom of upper cutter 1 is provided with upper cutter edge 3, the top of lower cutter 2 is provided with lower cutter edge 4, lower cutter 2 The position is fixed, the lower cutter edge 4 is parallel to the horizontal position, an acute angle less than 30 degrees is formed between the upper cutter edge 3 and the lower cutter edge 4, and the upper cutter 1 is connected with a cylinder 6 to move up and down and when it moves toward When moving down, an interlacing is formed between the upper cutter edge 3 and the lower cutter edge 4.

The material to be cut can be laid above the edge 4 of the lower cutter, and then the upper cutter 1 is driven down by the cylinder 6, and the edge 3 of the upper cutter and the edge 4 of the lower cutter are staggered to complete the cutting process of the material, similar to Scissors effect.

Wherein the upper cutter 1 is located on both sides of the upper cutter edge 3 and is provided with a downward extension 5. When the upper cutter 1 falls, the downward extension 5 will first fall on both sides of the lower cutter edge 4 before cutting. , to prevent the material from moving to the left and right during the cutting process and leaving the cutting area.

After a long time of use, the position of the upper cutter 1 and the lower cutter 2 will become loose. At this time, it is necessary to adjust the position adjustment bolts on the upper cutter 1 and the lower cutter 2, so that the edge 3 of the upper cutter and the edge 4 of the lower cutter are staggered. The tightness of the fit between them can ensure the best cutting effect.

In addition to the above embodiments, the utility model can also have other implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the utility model.
