Description
Technical field
The utility model belongs to metal cutting technology field, especially relates to a kind of cutting tool.
Background technology
Steel plate is one of material be most widely used in manufacturing industry, one of cutting main technique of daily metal foil is exactly utilize plate shearing machine cutting stock or shaping, or be the gas flame cuttiug techniques such as plasma or oxycetylene cut, for plate shearing machine cutting, cutter is layout in a row generally, can be made up of some blades, though this steel plate cutting tip can cut the steel plate of different lengths, but its cutter only cuts by simple Side by side groupings clamping, after its combination, cutter blade is not on the same line, steel plate edge after cutting or have burr, or owing to combining the space closely do not produced between each blade, and the cutting caused is not thorough, the harsh conditions such as steel plate adhesion, the blanking having a strong impact on steel plate is shaping.For gas flame cuttiug, the most obvious shortcoming is exactly that cutting edge burr is numerous, and, because heat in metal cutting produces chemical change around part of the steel plate, cause steel plate inside metallographic to change, have a strong impact on the using function of part of the steel plate.In view of the above problems, design a kind of board cutting tool and become a problem demanding prompt solution.
Utility model content
The purpose of this utility model is to solve the problems of the technologies described above, and provide a kind of sheet material cutting tool, this Tool in Cutting is functional, can cut the steel plate of different in width, and joint-cutting is neat and artistic, and cutting quality is good.
The technical solution of the utility model is as follows:
A kind of sheet material cutting tool, comprises fixture block, bolt, A blade, B blade and C blade; The both sides of described A blade are provided with tenon, and the partial cross sectional shape be connected with tenon is one trapezoidal, and blade is opened in trapezoidal wider one end; Described B blade and C blade cross section shape are trapezoidal shape, and its blade is all opened in trapezoidal narrower one end; The both sides of described B blade and the side of C blade are equipped with the groove matched with above-mentioned tenon; Described C blade is connected with A blade, the both sides of B blade are connected with A blade respectively, form a composite blade, described composite blade is clamped by fixture block, described fixture block is a concave architecture, the inclined-plane, both sides of its inside grooves two sides and blade fits tightly, and described bolt is pressed on described gang tool tightly through fixture block.
Beneficial effect: the utility model adopts tenon and groove split-mounting type structure, except the steel plate of different in width can be cut, effectively can also ensure each blade unit rear knife edge in a straight line, improve knife combination precision, obvious joint-cutting burr can not be produced when cutting, more there will not be cutting not thorough, the harsh conditions of steel plate adhesion.

Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this description can be well understood to other advantages of the present utility model and effect.
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Embodiment 1: as shown in Figure 1, a kind of sheet material cutting tool, comprises fixture block 1, bolt 2, A blade 3, B blade 5 and C blade 4.The concrete contour shape of insert is: the cross section of B blade 5 and C blade 4 is all identical trapezoidal, and the shape of cross section of A blade 3 is that above-mentioned two trapezoidal hypotenuses respectively with the addition of a parallelogram, and blade was opened on the trapezoidal end.Concrete structure is, the both sides of A blade 3 are provided with tenon, and blade is opened in trapezoidal wider one end; B blade 5 both sides are provided with the groove matched with above-mentioned tenon, and blade is opened in trapezoidal narrower one end; The side of C blade 4 is provided with the groove matched with above-mentioned tenon, and blade is opened in trapezoidal narrower one end.Above-mentioned cutter is formed three kinds of blade unit, and specifically C blade 4 is connected with A blade 3, and the both sides of B blade 5 are connected with A blade 3 respectively; Each blade above-mentioned relies on the cooperation between the tenon on respective blade or groove to carry out connection combination, forms an overall blade.After each blade unit is complete, clamp at the other end fixture block 1 of blade, this fixture block 1 is a concave structure, is provided with concave tracks in its inside grooves both sides panel, and in order to install restriction blade, blade can be free to slide in this track.Be fastened by bolts at fixture block 1 and the cutter combined, specifically on fixture block 1, offer three bolts hole, bolt is loaded in bolt hole, twist bolt downwards, make bolt end tightly be pressed in above-mentioned each blade upper end, realize the positioning and clamping of cutter.
Embodiment 2: as shown in Figure 6, for the steel plate that width is less, can directly adopt B blade 5 to cut, although B blade 5 both sides are provided with groove, but does not affect the clamping of fixture block 1, can directly use separately yet.
Embodiment 3: as shown in Figure 7, a kind of mode of the utility model blade unit, be made up of three pieces of blades, comprise fixture block 1, bolt 2, A blade 3, C blade 4, cut because this kind of combination is mainly used in slightly narrow steel plate, so do not need too many blade unit, so do not use above-mentioned B blade 5.
Further, be clamping blade better, bottom the concave tracks on the groove both sides panel of above-mentioned fixture block 1, make rough shape, with the frictional force increased and between blade two sides, firmly promptly blade.
Further, because the clamping force of fixture block 1 both sides to blade is upwards, for improving clamping force further, special is zigzag by above-mentioned rough shape, and the teeth directional of sawtooth is perpendicular to inclined-plane, blade both sides.
Further, the clamping for ease of this sheet material cutting tool uses, and above-mentioned fixture block 1 can be offered the counterbore of respective numbers, in order to construction bolt, avoids bolt head to emerge the end face of fixture block 1, affects cutter clamping and use.
The utility model is a kind of assemble type cutter, according to the width needs of cutting steel plate, can increase or reduce respective blade quantity and regulate tool length.Concrete knife number is odd number combination, also may be combined with out 7 pieces of blades, 9 pieces of blades even the cutter form of the multiple quantity such as 13 pieces of blades in addition to the above embodiments, while employing requirement blade unit, need be equipped with the fixture block 1 of corresponding length.The utility model can be used for as on the cutting apparatus such as plate shearing machine, and the concrete shape of fixture block 1 can do corresponding change according to the concrete cutting apparatus be used for, and is convenient to cutter clamping, or increase fixture carries out clamping to cutter, easy to use.
Because this tool length can need increase and decrease blade to adjust according to processing, cutting size range is large; Tenon socket joint is adopted to connect, not only easy to install, also can ensure each combination blade on the same line, prevent blade from misplacing, improve cutting quality.This modular cutting tool assembly also can effectively prevent conventional tool because of part edges tipping breach, and causes the overall situation of even scrapping of reprocessing of cutter to occur; Cold machining is adopted to steel plate, steel plate metallographic structure can not be caused to change, infringement serviceability.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
