Abstract
The utility model relates to an improved hole pattern processing cutter for an automobile air conditioner system pipe, belonging to a punching cutter. The utility model is provided with a rectangular knife body, a knife edge is positioned on an end of the short edge of the knife body, and the knife edge is formed by a cut angles generated by two equal inclined planes on the thickness surface of the knife body. The utility model is characterized in that the cut angle is 60 degrees, and a pinhole is arranged on the other short edge of the knife body. The processing cutter solves the problem that flowed head is easy to happen on workpieces when punching through enlarging the cut angle of the knife edge; the cutter installation mode is changed through the arrangement of the pinhole, thereby solving the problems that the cutter is easy to block because a pin roll is arranged in a inclined plane groove in the prior cutter installation, and the knife replacement is difficult.
Description
Technical field:
The utility model relates to punching cutter, is used for the moulding in the platoon leader hole on the air conditioning for automobiles concetrated pipe.
Background technology:
Concetrated pipe is a part on the condenser in the air conditioning for automobiles, at its tube wall the slotted hole of one row installation condensation flat pipe is vertically arranged, and this platoon leader Kong Shi is by stamping forming.Illustrated in figures 1 and 2 is the front and the side view of existing punching cutter, and knife edge angular is 45 °, and cutter hub one side has a surface groove A.Find in the production, when some workpiece is processed, when cutter is descending put in place after, still there is fully moulding of part in the aperture, makes workpiece produce overlap, when causing assembling, condensation flat pipe is difficult to smooth insertion, have in addition scrap.This be because, cutter is descending put in place after because the difference of material, cutter not exclusively is a B portion by the part of tube wall sometimes, but Fig. 2 sees in B portion and C portion.In addition, the installation of this cutter is to realize by place bearing pin formation restriction in the cone space of one group of cutter fixed head and cutter ramp groove A formation.Because stressed factor, cutter is easily stuck, and bearing pin can not taken out during tool changing, and tool changing is required great effort time-consuming very much.
Summary of the invention:
The purpose of the utility model provides a kind of improved air conditioning for automobiles concetrated pipe round process tool, produces the problem of overlap during with the solution punching on workpiece, in addition, also will make the replacing of cutter become easy.
Cutter after the improvement provided by the utility model is: have a rectangle cutter hub, blade is positioned at a short end of cutter hub, and blade is formed by the angle of cut that two inclined-planes that equate are produced at the thickness face of cutter hub, it is characterized in that the described angle of cut is 60 °; On the cutter hub of another minor face of cutter hub, be provided with a pin-and-hole.
The advantage of the cutter after the improvement is:
1, because knife edge angular becomes big, the intersection on blade inclined-plane and cutter hub plane is moved down, when punching, cutter B portion is the tube wall by workpiece fully, thereby moulding is complete, does not have overlap to produce, and condensation flat pipe is difficult for the situation generation of inserting when having avoided assembling.
2, the non-sword end at cutter is provided with pin-and-hole, and cutter can be fixed by the bearing pin that pierces, and the force-bearing situation of cutter and bearing pin all can improve, and cutter and bearing pin can not take place stuck, thereby tool changing is easy to, and tool change time shortens dramatically.
Description of drawings:
Fig. 1 is the front elevation of cutter before improving;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the utility model front elevation;
Fig. 4 is the side view of Fig. 3.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is explained.
Referring to Fig. 3, Fig. 4, the utlity model has a rectangle cutter hub, two short end of cutter hub, one end is a blade 1, the hole 2 that bearing pin passed when one end had a confession mounting cutter on the cutter hub of center, blade forms 60 ° the angle of cut at the thickness face of cutter hub by two inclined-planes 3 that equate, cutter hub adopts the uniform thickness body, is convenient to processing.
Claims (3)
1, improved air conditioning for automobiles concetrated pipe round process tool has a rectangle cutter hub, and blade is positioned at a short end of cutter hub, and blade is formed by the angle of cut that two inclined-planes that equate are produced at the thickness face of cutter hub, it is characterized in that the described angle of cut is 60 °.
2, improved air conditioning for automobiles concetrated pipe round process tool according to claim 1 is characterized in that, on the cutter hub of another minor face of cutter hub, is provided with a pin-and-hole.
