Abstract

The utility model relates to a thick plate cutting-off machine, in particular to a low energy consumption hydraulic heavy gate type cutting-off machine, which comprises a machine frame, top knife frames, bottom knife frames, an oil cylinder, transmission arms and fixed axles. Guide rails are mounted on both sides of the upper part of the gate type machine frame; the top knife frames are mounted in the guide rails in a sliding manner; the top knife frames are in meshing transmission with the evolute-shaped convex teeth ends of the transmission arms respectively arranged on both sides of the main bodies of the top knife frames through evolute-shaped concave teeth arranged on both sides of the main bodies of the top knife frames; the two transmission arms are respectively mounted on the machine frame through the fixed axles; the bottom parts of the both are respectively hinged with both sides of a double-acting oil cylinder; the bottom knife frames are correspondingly mounted under the top knife frames; clipping edges are respectively fixed on the top knife frames and the bottom knife frames. The cutting-off machine requires no other auxiliary materials during the cutting process, and does not consume steel materials, thereby ensuring high production efficiency; continuous and permanent cutting of thick plates can be realized; the cutting-off machine is suitable for cutting off various plates of 20 to 100 millimeter thickness, and can be widely applied in various industries such as iron and steel smelting, circulation, forgeable piece processing and blanking, waste recycling, etc.

Description

The heavy gate-type cutting machine of low energy consumption hydraulic

Technical field:

The utility model relates to thick template material cutting machine, the heavy gate-type cutting machine of especially a kind of low energy consumption hydraulic.

Background technology:

At present, the slab cutting does not still have special-purpose machinery, adopts Methods of OFC-A substantially.Gas cutting is the purpose that reaches cutting by the steel at high temperature melting scarfing place, and therefore quite big to the loss of steel, the waste residue of generation is not recycled value.Oxygen that gas cutting consumed and acetylene, the cost height, consumption is big, is unfavorable for long-term use continuously.Simultaneously, the gas cutting cutting also has certain danger, must just can be carried out in strict accordance with the safety regulation operation by the workman with qualifications for special job, can't satisfy the needs of batch process.Especially the extensive employing of steel industry continuously casting and continuously rolling technology, a large amount of tailings need utilize and deep processing again, and the cutting machine that presses for thick template material replaces traditional gas cutting.

Summary of the invention:

The technical problems to be solved in the utility model provides a kind of heavy gate-type cutting machine of low energy consumption hydraulic that thick template material cuts off that is exclusively used in, and to substitute gas cutting, overcomes the drawback that gas cutting exists.

The technical scheme that its technical problem that solves the utility model adopts is: the heavy gate-type cutting machine of a kind of low energy consumption hydraulic, comprise frame, upper tool post, lower slide, oil cylinder, transmission arm, fixed axis, guide rail is equipped with in described gate-type upper rack both sides, be slidingly fitted with upper tool post in the guide rail, this upper tool post is by its body both sides recessed tooth of involute shape that is provided with and the involute shape double wedge end meshing transmission that is divided into the transmission arm of its body both sides, two transmission arms are loaded on the frame by fixed axis respectively, both bottoms are hinged with the two-way cylinder both sides respectively, upper tool post below correspondence is equipped with lower slide, on, be fixed with shear blade on the lower slide respectively.

Compared with prior art, the beneficial effects of the utility model are: do not need other any auxilliary materials in the cutting-off process, steel itself are not produced consumption, the production efficiency height.Both guarantee the security of producing, also reduced the maintenance capacity of equipment.Normal operations workman only needs simple training, can produce smoothly by operational procedure.Can realize the lasting continuously shearing of thick template material, be applicable to the cut-out of the various sheet materials of 20～100 millimeters thick, can be widely used in numerous industries such as smelting iron and steel, circulation, forging processing blanking, waste recovery.

Description of drawings:

Fig. 1 is the two corner cut structural representations of the utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the side view of Fig. 1.

Fig. 4 is the utility model list corner cut structural representation.

Among the figure: frame 1, upper tool post 2, fixed axis 3, transmission arm 4, two-way cylinder 5, lower slide 6, two corner cut shear blade 7, the recessed tooth 8 of involute shape, involute shape double wedge termination 9, guide rail 10, single corner cut shear blade 11.

The specific embodiment:

The utility model is described in further detail below in conjunction with drawings and Examples.

The heavy gate-type cutting machine of a kind of low energy consumption hydraulic, the main part of its frame 1 is double-deck gate-type structure, top opposed inside face is equipped with guide rail 10, be slidingly fitted with the upper tool post 2 of platy structure in the guide rail 10, this upper tool post 2 is by its body both sides recessed tooth 9 of involute shape that is provided with and involute shape double wedge termination 8 engaged transmission that are divided into the transmission arm 4 of its body both sides, the transmission arm 4 of described upper tool post 2 both sides is installed in respectively on separately the fixed axis 3, this fixed axis 3 is loaded between the frame 1 upper part of double gate-type structure, two transmission arms, 4 bottoms are hinged with two-way cylinder 5 both sides that are fixed on frame 1 bottom respectively, upper tool post 2 below correspondences are equipped with lower slide 6, on, be fixed with shear blade 7 on the

lower slide

2 and 6 respectively.

In the present embodiment, being fixed in the shear blade 7 on the upper tool post 2, can be two corner cuts (as Fig. 1) or single corner cut (as Fig. 4).Two corner cuts are applicable to back plate slitting, and single corner cut is applicable to the cut-out of difformity material.

During work, two-way cylinder 5 promotes both sides transmission arm 4 around fixed axis 3 rotations, moves up and down along guide rail 10 thereby drive upper tool post 2, shears with lower slide 6 common realizations of being fixed on the frame 1.The power arm of transmission arm 4 is longer than resistance arm, and the output of two-way cylinder 5 small-powers by long power arm mechanical booster, realizes low energy consumption.
