Abstract
The utility model belongs to an improved shear blade of a rim shearing machine, which comprises an upper cutter body and a lower cutter body, wherein an inclined upper cutting edge is arranged below the upper cutter body, and an inclined lower cutting edge is arranged above the lower cutter body; the cutter is characterized in that the two sides of the upper cutter body are provided with inclined shoulder, and the two ends are provided with left and right cutter edge ends with the width smaller than that of the upper cutter body; the inner sides of two ends of the lower cutter body at two sides of the upper cutter body are made into lower cutter head inclined planes with the same inclination as the left and right cutting edges, and two ends of the upper part of the lower cutter body are provided with a left lower cutter head end and a right lower cutter head end with the width larger than that of the lower cutter body. The utility model discloses can not make upper and lower shear blade take place the displacement, ensure product shearing end face quality, the blade receives to use longe-lived, production efficiency is high.
Description
Technical Field
The utility model belongs to a part of cutter, in particular to rim cutter cutting edge improves.
Background
The present rim shearing machines are classified into parallel blade shearing machines, oblique blade shearing machines, disc type shearing machines, flying shear machines and roll-cutting type shearing machines according to the shape and configuration of blades and the condition of rolled pieces. The shearing machine with parallel blades is used mostly, the two shearing blades of the shearing machine are parallel, the lower edge can be fixed during shearing, and the shearing action is finished by the upper edge, so the shearing machine is called an upcut type parallel blade shearing machine. The shearing of the original shearing machine is completed by an upper shearing edge and a lower shearing edge which are respectively two lower shearing edges and one upper shearing edge. Due to the requirement on the end face of a cut finished product, the material to be cut can meet the requirement on the end face only by forming a certain angle with the horizontal plane to finish cutting during cutting, and thus the upper shear blade and the lower shear blade can respectively bear acting forces in opposite directions during cutting. The long-time continuous shearing can make the upper and lower shearing edges shift, the technical requirements of the shearing end face of the product cannot be guaranteed, the service life of the blade is short, the blade is frequently replaced, and the production efficiency is influenced.
Disclosure of Invention
The invention aims to overcome the technical defects and provide an improvement of a shear blade of a rim shearing machine, which changes the shapes of the blades of an upper cutter body and a lower cutter body and is in linear contact with the blades.
The utility model provides a technical problem, the technical scheme who adopts is: an improved shear blade of a rim shearing machine comprises an upper cutter body and a lower cutter body, wherein an inclined upper blade is arranged below the upper cutter body, and an inclined lower blade is arranged above the lower cutter body; the cutter is characterized in that the two sides of the upper cutter body are provided with inclined shoulder, and the two ends are provided with left and right cutter edge ends with the width smaller than that of the upper cutter body; the inner sides of two ends of the lower cutter body at two sides of the upper cutter body are made into lower cutter head inclined planes with the same inclination as the left and right cutting edges, and two ends of the upper part of the lower cutter body are provided with a left lower cutter head end and a right lower cutter head end with the width larger than that of the lower cutter body.
The beneficial effects of the utility model are that, this utility model can not make the upper and lower shear blade take place the displacement, ensures the product and cuts the terminal surface quality, and the blade is used longe-lived, and production efficiency is high.
Drawings
The following description is made in detail by way of example with reference to the accompanying drawings.
FIG. 1 is a front view of a modification of the shear edge of a rim shear;
FIG. 2 is a top view of FIG. 1;
FIG. 3 is a left side view of FIG. 1;
fig. 4 is a schematic view of fig. 1 at the time of cutting.
In the figure: 1-upper cutter body; 1-1-inclined upper blade; 1-2-left and right blade ends; 1-3-a beveled shoulder; 2-lower cutter body; 2-1-cutting left and right ends; 2-2-lower tool bit inclined plane; 2-3-inclining the lower blade; 3-workpiece.
Detailed Description
The embodiment refers to the attached drawings, and the improvement of the shear blade of the rim shearing machine comprises an upper cutter body 1 and a lower cutter body 2, wherein an inclined upper blade 1-1 is arranged below the upper cutter body 1, and an inclined lower blade 2-3 is arranged above the lower cutter body 2; the cutter is characterized in that two sides of an upper cutter body 1 are provided with inclined shoulders 1-3, and two ends are provided with left and right cutter edge ends 1-2 with the width smaller than that of the upper cutter body 1; the inner sides of two ends of the lower cutter body 2 at two sides of the upper cutter body 1 are made into lower cutter head inclined planes 2-2 with the same inclination as the left and right cutter edge ends 1-2, and two ends of the upper part of the lower cutter body 2 are provided with left and right lower cutter end heads 2-1 with the width larger than that of the lower cutter body 2.
The utility model discloses a theory of operation is: namely, the inner side of the lower cutter body 2 is made into a groove, the middle of the upper cutter body 1 is made into a boss, and the groove is contacted with the boss, so that the upper cutter body 1 cannot deviate.
The utility model discloses a use method is: the upper cutter body 1 is arranged on an upper shear blade carcass of the rim parallel blade shearing machine; the lower cutter body 2 is mounted on the lower shear blade carcass of the rim parallel blade shear. In operation, a workpiece 3 to be cut is placed on the lower cutter body 2. The shearing machine is started to press the cutter body 1 downwards to shear the workpiece 3.
