Abstract
The application provides a become arm-type industry scissors of power, including first shearing arm, second shearing arm, first shearing arm with the second shearing arm constitutes shears the mechanism, become arm-type industry scissors of power still includes first connecting seat, second connecting seat, connecting axle, first shearing arm, second shearing arm all are equipped with the connecting hole, connecting hole quantity is no less than three, beneficial effect: the length ratio of the power arm to the resistance arm, the shearing force and the shearing action edge length can be adjusted correspondingly according to the material to be sheared.
Description
Technical Field
The utility model relates to an industrial products, concretely designs a become power arm-type's industry scissors.
Background
The shearing and blanking of leather, plates and cloth made of different materials are needed in the industrial production process. When the cloth is sheared, excessive shearing force is not needed, and the scissors are needed to provide a longer shearing edge length, so that the shearing efficiency is ensured. Therefore, from a lever perspective, a longer resistance arm, a shorter power arm, is required. When cutting hard objects such as rubber, a long scissor power arm needs to be lengthened, and a short resistance arm needs to be used for increasing the cutting force. The prior art generally prepares different scissors for leathers made of different materials, and the prior art does not provide a pair of scissors with a multi-purpose knife.
Disclosure of Invention
The utility model overcomes the background art not enough provides a become arm-type industry scissors, designs and develops the aim at of this device, and the length ratio of the material adjustment power arm that this scissors can cut the preparation as required and resistance arm, corresponding adjustment shearing force and shearing action sword length.
The utility model provides a following technical scheme: the utility model provides a become arm-type industry scissors of power, includes first shearing arm 1, second shearing arm 2, first shearing arm 1 with second shearing arm 2 constitutes shears the mechanism, become arm-type industry scissors of power still includes first connecting seat 3, second connecting seat 4, connecting axle 5, first shearing arm 1, second shearing arm 2 all are equipped with connecting hole 6, three are no less than to connecting hole 6 quantity, connecting axle 5 runs through first connecting seat 3, first shearing arm 1, second shearing arm 2, second connecting seat 4, first shearing arm 1 runs through first connecting seat 3, second shearing arm 2 runs through second connecting seat 4.
The connecting shaft 5 is a screw rod, and one end of the connecting shaft 5 is screwed with a locking nut 7.
The utility model has the advantages that: the relative lengths of the power arm and the resistance arm are adjusted by correspondingly penetrating through different connecting holes 6 through the connecting shaft 5, the resistance arm is shortened when the power arm is lengthened, and the resistance arm is lengthened when the power arm is shortened. When the resistance arm is shortened, the labor is saved. Conversely, the resistive arm increases, tending to waste. The cloth, paper and other low-strength articles do not need to be cut in a labor-saving manner, a longer cutting length can be obtained by increasing the resistance arm, the cutting efficiency is increased, and the labor is saved when the aluminum sheet, the rubber sheet and other articles are cut. The connecting holes 6 at different positions can be adjusted according to actual conditions to assemble the product. Therefore, the length ratio of the power arm to the resistance arm, and the cutting force and the cutting edge length of the shearing action can be adjusted correspondingly according to the materials to be sheared and manufactured.
Drawings
Fig. 1 is a schematic perspective view of the variable arm industrial scissors of the present invention.
Fig. 2 is a schematic view of a connection relationship between the first shearing arm 1, the second shearing arm 2, the first connecting seat 3, the second connecting seat 4 and the connecting shaft 5, the first connecting seat 3 and the second connecting seat 4 are shown in a cross section along a radial direction in fig. 2, and the first shearing arm 1 and the second shearing arm 2 are shown in a cross section.
Detailed Description
The invention is further described with reference to the following detailed description of embodiments and drawings.
In fig. 1 and 2: the shearing device comprises a first shearing arm 1, a second shearing arm 2, a first connecting seat 3, a second connecting seat 4, a connecting shaft 5, a connecting hole 6 and a locking nut 7.
The variable force arm type industrial scissors comprise a first shearing arm 1 and a second shearing arm 2, wherein the first shearing arm 1 and the second shearing arm 2 form a shearing mechanism, namely the first shearing arm 1 and the second shearing arm 2 form a scissor mechanism. Become arm-type industry scissors of power still includes first connecting seat 3, second connecting seat 4, connecting axle 5, first shearing arm 1, second shearing arm 2 all are equipped with connecting hole 6, three are no less than to connecting hole 6 quantity, and the ratio scope that sets up more power arm that can provide the adjustment and resistance arm is big more.
The bodies of the first connecting seat 3 and the second connecting seat 4 are provided with holes for the connecting shaft 5 to penetrate through, and the hole axes of the holes are coaxial with the central axes of the first connecting seat 3 and the second connecting seat 4. Then the connecting shaft 5 penetrates through the first connecting seat 3, the first shearing arm 1, the second shearing arm 2 and the second connecting seat 4, specifically, the connecting shaft 5 penetrates through the connecting holes 6 arranged on the first shearing arm 1 and the second shearing arm 2 and the holes of the first connecting seat 3 and the second connecting seat 4, and the first shearing arm 1, the second shearing arm 2, the first connecting seat 3 and the second connecting seat 4 are connected in series. A cutting arm hole for the first cutting arm 1 and the second cutting arm 2 to pass through is further arranged along the diameter direction of the first connecting seat 3 and the second connecting seat 4. Then, the first cutting arm 1 penetrates the first connecting seat 3, and the second cutting arm 2 penetrates the second connecting seat 4.
The connecting shaft 5 is a screw rod, one end of the connecting shaft 5 is screwed with the locking nut 7, the purpose of tightly connecting all parts is achieved, meanwhile, the shearing gap can be reduced, and the shearing quality is improved.
