Description

Powerful manual shearing device

Technical Field

The utility model relates to a powerful manual shearing mechanism belongs to the manufacturing pincers industry shearing equipment technical field.

Background

During the shearing operation of the metallurgical manufacturing industry, objects needing to be sheared or torn off can be sheared by scissors, and when the needed force is larger than the maximum force which can be provided by the manual work, the objects cannot be sheared when the manual shearing is carried out.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a powerful manual shearing mechanism can provide the maximum power that surpasses people and can provide with the help of hand jack to utilize the principle of lever, cut the unable article of directly cutting through the manpower, solve the problem that exists among the background art.

The technical scheme of the utility model is that:

a powerful manual shearing device comprises a base, a jack, upper scissors, a rotating shaft, a connecting plate, lower scissors, a supporting upright post, a scissor handle and a fixing bolt, wherein the supporting upright post and the jack are respectively fixed on the base; go up the scissors and link together through the connecting plate between the scissors down, the connecting plate is the rectangle, and the upper end in the connecting plate length direction is rotated through pivot and the one end that last scissors is close to the scissors handle and is connected, and the one end fixed connection that the lower extreme in the connecting plate length direction is close to the support post through fixing bolt and lower scissors.

The length of the scissor handle is larger than that of the upper scissor.

The length of the scissor handle is twice as long as that of the upper scissors.

The fixing bolt is located under the rotating shaft.

The utility model has the advantages that: the manual jack can provide the maximum force exceeding the force provided by people, and the lever principle is utilized to cut off objects which cannot be directly cut off by manpower.

Drawings

FIG. 1 is a schematic structural view of the present invention;

in the figure: base 1, jack 2, go up scissors 3, pivot 4, connecting plate 5, lower scissors 6, support post 7, scissors handle 8, fixing bolt 9.

Detailed Description

The invention will be further explained by way of example with reference to the accompanying drawings.

Referring to the attached figure 1, the powerful manual shearing device comprises a base 1, a jack 2, an upper shear 3, a rotating shaft 4, a connecting plate 5, a lower shear 6, a supporting upright post 7, a shear handle 8 and a fixing bolt 9, wherein the supporting upright post 7 and the jack 2 are respectively fixed on the base 1, one end of the lower shear 6 is fixed on the supporting upright post 7, the upper shear 3 is positioned right above the lower shear 6, one end of the shear handle 8 and the upper shear 3 form an integral structure, and the jack 2 is propped against the other end of the shear handle 8; go up and link together through connecting plate 5 between scissors 3 and the lower scissors 6, connecting plate 5 is the rectangle, and the upper end on the 5 length direction of connecting plate is rotated through pivot 4 and the one end that last scissors 3 is close to scissors handle 8 and is connected, and the lower extreme on the 5 length direction of connecting plate passes through fixing bolt 9 and the one end fixed connection that lower scissors 6 is close to support post 7.

In this embodiment, referring to fig. 1, the length of the scissor handle 8 is twice the length of the upper scissor 3 to increase the shearing moment, and the jack 2 and the scissor handle 8 are connected together by welding so as to be firm and transmit the moment.

At least one of the upper scissors 3 and the lower scissors 6 has a sharp blade, or both of them have sharp blades, so as to cut hard objects.

The fixing bolt 9 is located right below the rotating shaft 4.

The specific shearing process is as follows:

a. when the common manual scissors cut continuous articles, the articles are placed between the upper scissors 3 and the lower scissors 6;

b. the jack 2 is manually started, the jack 2 is slowly forced, the rotation function of the rotatable shaft 4 is utilized, when the jack 2 is jacked, the lever principle is utilized, the moment is transmitted to the upper scissors 3 through the scissors handle 8 and acts on an object to be cut, and therefore the object is cut.
