Technical Field

The invention relates to the technical field of waste metal material processing, in particular to an upper shearing tool apron for special-shaped steel hydraulic gantry type shearing equipment.

Background

The hydraulic gantry type shearing equipment is scrap steel processing equipment which is multifunctional, high in automation degree and high in operation efficiency. The novel alligator shearing machine not only has the shearing mechanism of the alligator shearing machine, but also has auxiliary devices such as a material box, a material box gland, a turnover mechanism, a feeding mechanism, a side pressing mechanism, a pressing mechanism, mechanical charging and the like, and is suitable for shearing various waste steels with various mixed shapes, such as metal structural parts, automobile parts and various recycled waste steels.

The hydraulic system of the hydraulic gantry type shearing equipment consists of auxiliary parts such as a hydraulic pump (driven by a motor), a hydraulic cylinder, a hydraulic control valve, a hydraulic pipeline, an oil tank, a filter and the like, and the number of the auxiliary parts can be different according to different models of gantry type shearing machines.

Aiming at electric furnace steelmaking and inconvenient furnace use of throwing of abnormal shape old and useless metal, a single-knife type deformed steel hydraulic gantry type shearing equipment is provided in the market, the equipment adopts the jaw biting of a single blade to realize the shearing of the deformed steel, the effect that the abnormal shape metal can be conveniently thrown into the furnace for use is achieved through repeated shearing and the combined use of a steel briquetting machine, and the equipment has the following defects: the cutting size of the profiled bar cannot be determined; the furnace feeding size can be achieved by cutting for many times, and the efficiency is low; the size requirement can be met by combining the metal briquetting machine, so that the cost is increased; the inconvenient later maintenance of cutter connected mode has increased the cost of labor.

Disclosure of Invention

In order to solve the technical problems, the invention discloses an upper shearing tool apron for profiled bar hydraulic gantry type shearing equipment, which adopts a method of fixing a blade by a boss, so that the blade and the tool apron are firmly fixed, a positioning pin and a screw cannot be deformed, and later-stage disassembly and maintenance are convenient.

The invention adopts the following specific technical scheme:

the utility model provides an go up the shearing blade holder for deformed steel hydraulic pressure planer-type shearing equipment, use integrative welding technique to make, wholly be right trapezoid, the one side of should going up the shearing blade holder is provided with a plurality of milling flutes and is used for welding the boss, the shape of boss is the rule tetrahedron, the shearing position of should going up the shearing blade holder bottom is provided with the location strip, evenly be provided with circular locating hole on the location strip, the locating hole passes through screw fixedly connected with blade, the bottom shearing position of boss is provided with the location strip, evenly be provided with circular locating hole on the location strip, the locating hole passes through screw fixedly connected with blade.

In above-mentioned technical scheme, provide pressure lift through the shearing hydraulic cylinder that welds at last shearing blade holder and cut the blade holder and reach the shearing effect on, weld the steel that makes after the extrusion reach the size through the cooperation of the boss design that increases to weld on cutting the blade holder and polylith cutter, reach and cut out polylith steel, raise the efficiency, conveniently throw the effect of stove.

The invention further improves that the shape of the boss positioning strip is set to be rectangular or cross-shaped, and the boss positioning strip can be matched with blades with different rules for use.

The invention is further improved, the edges of the vertical rods at the two sides of the upper shearing tool holder are designed to be cylindrical or triangular, and the vertical rods are matched with the rails in the side supports at the two sides of the gantry frame of the shearing mechanism and can slide up and down.

The invention is further improved, and the connecting part of the upper shearing tool apron and the hydraulic cylinder is in a semicircular design.

The invention further improves the structure that a plurality of reinforcing ribs are vertically arranged on the back of the boss of the upper shearing knife seat, the reinforcing ribs are connected with a fixing table, a positioning strip is arranged on the fixing table, and a positioning hole is formed in the positioning strip and used for installing a blade.

The shearing hydraulic oil cylinder welded on the upper shearing tool rest provides lifting power, the shearing hydraulic oil cylinder pushes the upper shearing tool rest to shear steel downwards, and the shearing hydraulic oil cylinder provides tension to pull up the tool rest after shearing; the upper shearing tool apron is integrally cast, so that the strength of the upper shearing tool apron is improved, and the weight of the upper shearing tool apron is reduced; the upper shearing tool holder is provided with a milling groove matched with the boss, so that the boss is convenient to position and weld, and the effect of shearing a plurality of finished products at one time is achieved by adding the boss; the upper shearing knife holder and the boss are matched with a knife for slotting according to 9-10 degrees, positioning keys (two types of transverse key grooves/cross key grooves) are added, the positioning strength is improved, the abrasion deformation of a positioning surface is reduced, and the later maintenance is facilitated.

The invention has the beneficial effects that: according to the invention, the design of the upper cutter boss is added on the upper shearing cutter holder, and the plurality of cutters and the pressing device are used in a matched manner, so that the determination of shearing size is achieved, and the production efficiency is improved by shearing a plurality of raw materials.
