Abstract

The invention relates to a rip cutting upper cutter structure for an air conditioner fin die. The rip cutting upper cutter structure for the air conditioner fin die comprises a rip cutting upper cutter body, a first bevel, a third bevel, a first horizontal plane, a second bevel, a second horizontal plane, a first circular arc and a second circular arc. The first bevel and the third bevel are arranged at the two ends of a blade of the rip cutting upper cutter body respectively. The first horizontal plane, the second bevel and the second horizontal plane are further arranged on the portion, between the first bevel and the third bevel, of the blade in sequence. A height difference L is formed between the first horizontal plane and the second horizontal plane. The first circular arc and the second circular arc are further arranged on the blade of the rip cutting upper cutter body. The rip cutting upper cutter structure for the air conditioner fin die is simple in structure and convenient to use. Due to the fact that a first fillet and a second fillet are arranged at the two ends of the rip cutting upper cutter body respectively, cutter connecting marks generated by blanking of fins are effectively controlled, and the deformation of materials on the rip cutting portion is reduced. Meanwhile, due to the fact that the height difference is designed on the blade of the rip cutting upper cutter body, two fins with different lengths can be formed through cutting, and the production efficiency is greatly improved.

Description

A kind of top slitter structure for air-conditioner fin die
Technical field
The present invention relates to air-conditioner fin process equipment, particularly relate to a kind of top slitter structure for air-conditioner fin die.
Background technology
Rip cutting also known as opening bar, its effect be utilize the upper and lower cutter of rip cutting to cutting, by wide for the material of the view picture fin width be cut into required by client.The upper and lower cutter of rip cutting to cut length control lapping defect, reduce fin distortion aspect play a part very important.If too short to cutting length, connect cutter and do not connect, fin can't cut.If oversize to cutting length, lapping defect obviously and to connect the fin distortion of cutter place severe.At present, the upper and lower knife-edge shape of existing rip cutting is designed to intersection point and adds chamfering, and the structure of the upper and lower cutter of above-mentioned rip cutting can form obvious lapping defect after stamping-out on fin, easily produces burr, and material easily produces distortion in rip cutting place simultaneously, greatly have impact on production efficiency.
Summary of the invention
The applicant is for above-mentioned existing issue, be studied improvement, provide a kind of top slitter structure for air-conditioner fin die, the present invention can not only effectively control to connect tool marks, reduce controlling distortion, also realized the stamping-out of two kinds of different length fins by adjustment edge of a knife penetraction depth.
The technical solution adopted in the present invention is as follows:
For a top slitter structure for air-conditioner fin die, comprise top slitter body, the first inclined-plane and the 3rd inclined-plane are set respectively in the two ends of the blade of described top slitter body; Between described first inclined-plane and the 3rd inclined-plane, on described blade, also order arranges the first horizontal plane, the second inclined-plane and the second horizontal plane; Height of formation difference L between described first horizontal plane and the second horizontal plane; On the blade of described top slitter body, also the first circular arc and the second circular arc are set respectively.
Its further technical scheme is:
Described first circular arc is arranged at the junction of first horizontal plane one end and the first inclined-plane minimum point, the first horizontal plane other end and the junction of the second inclined-plane peak and the junction of the second inclined-plane minimum point and second horizontal plane one end respectively; The arc radius value of described first circular arc is R5 ± 0.01;
Described second circular arc is arranged at the junction of the second horizontal plane and the 3rd inclined-plane minimum point; The arc radius value of described second circular arc is;
The difference of described difference in height L is 0.7 ± 0.02;
Form α angle between described first inclined-plane and horizontal plane, described α angle is 15 ° ± 0.01 °; Form β angle between described second inclined-plane and horizontal plane, described β angle is also 15 ° ± 0.01 °;
Described 3rd forms γ angle between inclined-plane and horizontal plane, described γ angle is 45 ° ± 0.01 °;
Multiple installing hole is also had on described top slitter body.
Beneficial effect of the present invention is as follows:
Structure of the present invention is simple, easy to use, by the two ends at top slitter body, the first rounding and the second rounding are set respectively, what effectively control fin stamping-out connects tool marks, reduce the distortion of material in rip cutting place, the fin of two kinds of different lengths can be cut out simultaneously by the difference of design height on the blade of top slitter body, substantially increase production efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 and Figure 2, a kind of top slitter structure for air-conditioner fin die comprises top slitter body 1, also has multiple installing hole 101 on top slitter body 1.First inclined-plane 103 and the 3rd inclined-plane 107 are set respectively in the two ends of the blade 2 of top slitter body 1; Between the first inclined-plane 103 and the 3rd inclined-plane 108, on blade 2, also order arranges the first horizontal plane 104, second inclined-plane 105 and the second horizontal plane 106; Between first horizontal plane 104 and the second horizontal plane 106, the difference of height of formation difference L, difference in height L is 0.7 ± 0.02.First circular arc 102 and the second circular arc 107 is also set respectively on the blade 2 of top slitter body 1.As shown in convex, above-mentioned first circular arc 102 is arranged at the junction of first horizontal plane 104 one end and the first inclined-plane 103 minimum point, first horizontal plane 104 other end and the junction of the second inclined-plane 105 peak and the junction of the second inclined-plane 105 minimum point and second horizontal plane 106 one end respectively; The arc radius value of the first circular arc 102 is R5 ± 0.01.Above-mentioned second circular arc 107 is arranged at the junction of the second horizontal plane 106 and the 3rd inclined-plane 108 minimum point; The arc radius value of the second circular arc 107 is.Form α angle between first inclined-plane 103 and horizontal plane, α angle is 15 ° ± 0.01 °; Form β angle between second inclined-plane 105 and horizontal plane, β angle is also 15 ° ± 0.01 °.Form γ angle between 3rd inclined-plane 108 and horizontal plane, γ angle is 45 ° ± 0.01 °.
During work, always cutting upper slitter body 1 is arranged on slit sub-die plate by installing hole 101, top slitter makes relative cutting movement with cutter under rip cutting in the course of the work, the material of feeding is cut, after upper bottom knife stamping-out, owing to arranging the first circular arc 102 on the blade 2 of top slitter body 1, second circular arc 107, therefore tool marks are connect after effectively controlling stamping-out, decrease material deformation, when the second horizontal plane 106 of blade 2 in top slitter body 1 realizes the first length with material, when top slitter body 1 continues descending, in top slitter body 1, the first horizontal plane 104 of blade 2 continues to realize the die-cut of material the second length with material.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention is see claim, and when without prejudice to basic structure of the present invention, the present invention can do any type of amendment.
