Description of the Invention: [Technical Field] The present invention relates to a cutter, and more particularly to a cutter cutter structure for perforating paper for a transaction. [Prior Art] Generally, the cutter of the conventional punching machine is shown in the tenth and eleventh drawings. The cutter 4 is pivotally mounted on the blade frame 5, and the cutter 4 is a solid cylindrical structure and is in the cylinder. The circumference of the circumference forms a v-shaped groove with a knife edge, and a horizontally pointed blade edge 41 is defined on the periphery of the V-shaped groove, and the groove-shaped circumferential bread of the groove has a flat inner edge 42 and an upper curve The surface 43 can be used to produce the paper stack a and the space for forming the paper dust after cutting. The vertical distance from the highest point of the upper curved surface 43 to the horizontal line of the apex edge of the oblique edge 41 is set to the valley depth h. The second test = the twelfth figure, the vertical axis is set as the power amount kg (10), the horizontal axis j paper ^ page number \ is known from the drawing, when the tool 4 of the inverted v-shaped groove is at the time, the depth h is For different page counts, the thickness of the hole is 4, and the average of f 2 () kg, 2q = = flat Γ 48·4 kg, 3 〇 page stack, 63 kg, 40 pages. The paper stack requires an average of 95 ^ ^ 120 kg. ...50 pages of paper stacking average [invention content] (the technical problem to be solved) 201117938 Only the inventor found that the tool of the conventional punching machine is the first to contact the paper with the two-point horizontal tool tip. = Pressing down to punch the hole, because the tool tip is leveled, etc.: the tool will be pressed against the paper stack at the beginning of the punching: f resistance 'the initial cutting resistance it suffers is large, The cost of the effort -= step by step is carried out in the gradual manner, usually it is necessary to pluck the groove on the circumference of the bottom of the tool: δ ten, the paper scrap b formed after the punching is centered in the upper curved surface: ::: Squeeze in: etc. - between the slots, due to the paper two: second degree? Therefore, the resistance encountered by the flat side of the tool is also quite increased. 2 - The more difficult punching situation; therefore, the above-mentioned first question, the present invention is necessary to solve.

(Compared with the efficacy of the prior art) It is clear from the above description that the present invention has the following effects compared to the prior art: 1. The initial resistance of the tool of the present invention is generated by the oblique edge of the knife, mainly in punching. The sharp edge before the edge of the knife edge is cut along the sides of the slanted edge 201117938, and ends at the sharp edge of the edge of the oblique edge, so that the drilling resistance is generated in a single point manner, which can reduce the tool. The comprehensive resistance to contact with the paper stack and the punching effect can save the effect of punching holes. 2. The chip-removing rod in the hollow cavity of the invention has the function of automatically withdrawing the paper scraps, which has the doubts of avoiding the paper chip jamming tool, and can reduce the resistance of the tool to the paper stack, and the effect of smooth punching according to the labor saving. [Embodiment] Referring to Figures 1 to 4 in May, the present invention relates to a punching machine tool structure, comprising: a punching seat 1' having a knife frame 1 1 on the punching seat 1; a pressing member 2, the pressing member 2 is provided with a pressing arm 2 1, the pressing arm 21 is pivoted with the knife frame 11 of the punching seat 1; a cutter 3 is a cylinder of a hollow receiving groove 3 i at the bottom of the cutter 3 The end is formed with a cutting edge of the cutting edge 3 2 , and the tool 3 is provided with a pivot hole 3 3 ′. The tool frame 3 is pivoted to the knife frame 1 of the punching seat 1 by the pivot rod 2 2 The angle Θ of the oblique edge 3 2 and the paper stack A may be between 15 and 5 G degrees, and the vertical distance between the front edge 3 2 1 and the edge 3 2 2 of the oblique edge 3 2 is the edge of the blade. The length Η, the inner edge of the trough 3 1 of the cutter 3 is provided with a class abutting portion 34, and the space below the abutting portion 3 4 is formed to form a retreating port 35, which is provided in the trough 3 1 In the factory, the chip retracting rod 3 6 , the spring 3 7 , the spring 3 7 can actuate the pushing and retracting rod 3 6 ' for the paper > 1 Β to retreat; i π 3 5 to exit. Referring to the first to third figures, the puncher tool 3 of the present invention is implemented in 201117938, 'putting the retracting shoulder rod 36 and a spring 3 7 into the trough 3 1 of the cutter 3'. In the knife frame 1 1 of the punching seat 1, the pressing arm 21 of the member 2 is pivoted to the blade frame 11, and the pressing arm 2 1 of the pressing member 2 and the pivot hole of the cutter 3 are pierced by the - pivot 2 2 3 3 pivotally fixed, so that the chip removing rod 3 6 is resisted by the spring 3 7 and positioned on the abutting portion 3 4 of the receiving groove 3 1; also refer to the drawing of the punching machine tool structure In the implementation, the pressure arm 2 of the pressing member 2 drives the oblique edge 3 2 of the cutter 3 to the upper layer of the paper stack A by the sharp edge 3 2 before the edge 3 2 of the cutter 3 is used. At the time, only the single point resistance of the front sharp edge 3 2 i is continuously pressed downward to punch the hole, and the two sides of the front sharp edge 3 2 1 are gradually pushed toward the paper stack a Cut through, at this time, the paper scraps B that have not been cut by the king enter the retreating port 3 5 and abut against the end of the chip retracting rod 36, which is pressed by the paper stack a to continue the upward compression spring 3 7 , when the tool 3 is drilled down again, it is transformed into a bevel edge. 3 2 The single point resistance of the last edge 3 2 2, the finished tool 3 completely cuts the paper scraps B of the paper stack a. When the paper scraps B are cut through, the resistance of the cutter 3 is lost, and the tolerance of the cutter 3 is The spring b 7 of the paper b-compression will elastically press the chip retracting rod 3 6 downward, so that the paper scraping B is pushed out from the retreating port 35 to complete the action of the tool 3 to punch the paper stack A; Please refer to the fifth to ninth diagrams, the vertical axis of the drawing is set as the power summer kilogram (kg), the horizontal axis is set to the angle 0 of the oblique edge 3 2 and the paper stack a, and the oblique edge of the cutter 3 The angle 0 (edge length Η ) between the edge 3 2 and the stack a is 16 degrees (2 mm), 23. 2 degrees (3 mm), 29. 7 £ y 6 201117938 degrees (4 halls), 35.5 degrees (5 coffee) 48. 8 degrees (8 〇, for playing 6 degrees (6 coffee), 45 degrees (7 coffee), 4 〇 ^ 50 MmZZ 〇 W'2 〇 M ' 3 〇 please - and compare the tenth: Diagram of the diagram of the power quantity curve of the figure; '舻再舻-立国一图 is the power consumption ratio of the invention and the conventional use is not thinking' The upper curve is kg, 20 pages / 4" kg: bud through 10 pages / 20 · 6

The preferred power is 9·24 kg, and the 2G page stack is 18.68 kg' 30-sheet overlap 35. 5 degrees is 36 52 kg, 4 sheets of paper stacking 35.5 degrees for % kg, 5G sheet stacking 35.5 degrees for 76 a kg. Compared with the conventional use of the present invention, the cutter 3 of the present invention has a labor-saving effect; The power amount map selected as a better labor-saving angle can be seen from the fifth to the nineth views. The power of the present invention at other angles is also less labor-intensive. In summary, the "punch cutter tool structure" of the present invention refers to a hollow cutter having a hollow pocket and having a beveled edge, by the angle between the edge of the knife and the paper stack. When the edge of the oblique knife is punched, the resistance is generated in the single point manner on the front and the end edge respectively, which can reduce the full contact of the tool with the paper stack, and the chip retracting rod in the container can be automatically The paper scraps out, which has the doubts of avoiding the paper scraping tool, and can reduce the resistance of the paper to the paper stack.
