Description
Technical Field
The utility model relates to a shear blade especially relates to a section with direction.
Background
The plastic raw materials are added into a forming machine, the raw materials are melted by heating a charging barrel, a cylindrical blank is formed after the raw materials are melted, the blank sags to a set position, and a front cutter and a rear cutter are closed to cut off the blank. In production, when a craftsman adjusts the speed of the cutter, the cutter often collides, and spare parts are damaged. When the old blade is used for debugging a machine, the blank is cut off, the cutting edges of the front blade and the rear blade are easy to collide, and the cutting edges of the blades are damaged or even scrapped.
Disclosure of Invention
The invention provides a guide cutter, aiming at solving the problem that the cutter causes collision in the cutter setting process, and the guide cutter comprises a connecting part, wherein the front end of the connecting part is provided with a cutter edge part, the cutter edge part comprises a cutting edge, two sides of the connecting part are provided with guide parts, the guide parts are used for guiding the cutter to be closed for staggered shearing, and the guide parts are positioned at the front end of the cutting edge.
Preferably, the connecting part and the guide part are rectangular blocks, and the upper end face and the lower end face of the guide part and the upper end face of the connecting part are flush, smooth and flat.
Further, the connecting portion is provided with a mounting groove. The cutter is installed with the frame through the mounting groove in a matching mode.
Preferably, the blade portion further includes a cutting slope, and the cutting edge is located at a front end of the cutting slope.
Further, the guide part is a guide inclined plane, and the direction of the guide inclined plane is opposite to that of the cutting inclined plane. In the closing process of the cutter, the cutting edge of the upper cutter may be lower than that of the lower cutter, and the guide inclined plane of the upper cutter is matched with that of the lower cutter to guide the upper cutter and the lower cutter to cut in a staggered manner when the upper cutter and the lower cutter are closed.
Preferably, the guide portion is a guide arc, and the guide arc is arranged close to the cutting edge. In the closing process of the cutter, the cutting edge of the upper cutter may be lower than that of the lower cutter, and the guide arc of the upper cutter is matched with that of the lower cutter to guide the upper cutter and the lower cutter to cut in a staggered manner when the upper cutter and the lower cutter are closed.
Has the advantages that: the utility model can prolong the service life of the front and the rear blades; collision or extrusion of the front and rear blades is effectively avoided; the accuracy and the cutting speed that the material embryo cut off have been improved, the utility model discloses simple structure has improved production efficiency effectively.

Detailed Description
Example 1
As shown in fig. 1, a guiding cutter, the cutter includes connecting portion 5, the 5 front ends of connecting portion are equipped with cutting edge portion, cutting edge portion includes blade 1, 5 both sides of connecting portion are equipped with guiding part 3, guiding part 3 is used for guiding the cutter closure to carry out crisscross shearing, guiding part 3 is located 1 front end of blade. Connecting portion 5 with guide portion 3 is the rectangular block, guide portion 3 with two terminal surfaces about connecting portion 5 flush and smooth level. The connecting portion 5 is provided with a mounting groove 7. The blade part further comprises a cutting inclined plane 2, and the cutting edge 1 is located at the front end of the cutting inclined plane 2. The guide part is a guide inclined plane 4, and the direction of the guide inclined plane 4 is opposite to that of the cutting inclined plane 2.
The specific working principle is as follows: two upper and lower cutters are fixed in the frame through the mounting groove 7 of connecting portion 5, the cutting inclined plane 2 of top cutter is upwards, the cutting inclined plane 2 of below cutter is installed downwards, when two closed in-process of cutter, if the blade 1 position of going up the cutter is less than the blade 1 of cutter down, perhaps the blade 1 position of going up the cutter flushes with the blade 1 of cutter down, the closure can cause the cutter to damage like this, at this moment, in closed in-process, the direction inclined plane 4 of cutter contacts earlier, the cutter up respectively and down motion about the guide, make the blade 1 position of going up the cutter be higher than the blade 1 of cutter down, again because the terminal surface of guide 3 and connecting portion 5 flushes, go up the lower terminal surface of cutter connecting portion 5 and paste the up end face of cutter connecting portion 5 down, thereby can accomplish the cutter tool setting debugging.
Example two
The difference from the embodiment is that: the guiding part 3 is a guiding arc 6, and the guiding arc 6 is close to the cutting edge 1. At two upper and lower cutter closure in-process, if the blade 1 position of going up the cutter is less than blade 1 of cutter down, perhaps the blade 1 position of going up the cutter flushes with blade 1 of cutter down, direction circular arc 6 can take over the first contact, the cutter up respectively and down motion about the guide, make the blade 1 position of going up the cutter be higher than blade 1 of cutter down, again because the terminal surface of guide part 3 and connecting portion 5 flushes, go up the lower terminal surface of cutter connecting portion 5 and paste the up end of cutter connecting portion 5 down tightly, thereby can accomplish the cutter and debug to the cutter.
