Abstract
The utility model provides a bended tool, which belongs to the technical field of mechanical manufacture equipment. The bended tool comprises an upper tool and a lower tool; wherein the upper tool is an integral structure of a connector and a tool body. The tool body is an inverted-L structure with a bending angle of less than 90 degrees; the lower end of the tool body is provided with a tool tip integrated with the tool body. The lower tool is a regular prism structure; the three continuous surfaces on the upside of the bottom are provided with one more cut grooves. The lower tool is a regular quadrangular structure. The section of the tool grooves is an inverted equilateral right-angled triangle. The bended tool is applied to practical production operation; the minimal bended size of the work-piece basically meets the design requirement; moreover, the depth of the U-shaped bend is about twice of the original bending depth, thereby achieving better expected effect, ensuring the one-time adaptation of the tool length along with the size variation of the bending parts, overcoming the disadvantage of lack of appropriate tool during tool split and accelerating the bending speed.
Description
Technical field
The utility model relates to technical field of mechanical manufacturing equipment, specifically a kind of bending cutter.
Background technology
General, the product of the bending cutter of now being produced is substantially to be customized to the master, product structure is comparatively complicated, most of structural member is the sheet metal bending and forms, not only parts are various in style, and the size of the specification of parts and bending differs, and brought certain degree of difficulty so just for processing department, and also the requirement to the bending operated implement increases.According to existing bender cutter condition survey: the parts that 1, can not roll over reduced size.2, can not the darker U type parts of bending degree.3, the aesthetic appearance of R angle considerable influence parts after the parts bending.4, bending cutter and element size do not match, and can not find suitable cutter when piecing together cutter, have influenced speed of production and quality.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, provides a kind of in order to adapt to the characteristic of product, at existing general bender size, the rapid processing of the multiple bending parts of specially designed a adaptation different size and the bending cutter of production.
The technical solution of the utility model realizes in the following manner, this bending cutter, its structure comprises upper slitter and following cutter, upper slitter is connector and blade unitary whole structure, and blade is inverted "L" shaped, and the blade bent angle is less than 90 °, the lower end of blade is provided with the point of a knife with the blade one, the point of a knife wedge angle is 90 °, and following cutter is the regular prism structure, wherein offers the cutter groove of an above quantity on continuous three faces in bottom surface top.
Following cutter is the four-prism structure.
Offer four cutter grooves on the upper surface of following cutter, in the middle of wherein big groove was arranged on, little groove was arranged on both sides, and four cutter grooves are parallel to each other.
The both sides of following cutter upper surface respectively offer three cutter grooves on relative two surfaces, and in the middle of wherein big groove was arranged on, little groove was arranged on both sides, and three cutter grooves are parallel to each other.
Cutter groove cross section is down equilateral right angled triangle.
The beneficial effect that the utility model is compared with prior art produced is:
The design of the inverted "L" shaped blade of this bending cutter has strengthened the indent size of last tulwar, and whole height, and changed the indent direction of traditional big tulwar, move after making the pressure size of bending cutter, reduced the bending cutter because pressure is excessive, reach concavity and cross the cutter distortion phenomenon that is easy to generate deeply, make the bending cutter increase the degree of depth of bending.But the following cutter of this bending cutter makes the as close as possible edge of cutter groove of cutter down under the situation of cutter ability to bear, so just can obtain as far as possible little bending size.The bending cutter that used size all can be mated rapidly during the parts bending.The mounting means of this bending cutter is basic identical with the mounting means of existing bender cutter, needn't transform existing bender again, has made full use of the function of existing equipment.This bending cutter is applied to the production practical operation, the minimum dimension of workpiece institute bending reaches designing requirement substantially, and deeply nearly one times of the original bending size of the curved depth ratio of folding U type, obtained reasonable pre-its effect, and can be along with the variation of bending element size, tool length can adapt to one-time-reach-place substantially, has reduced the disadvantage that can not find suitable cutter when piecing together cutter, has improved the speed of bending.
Description of drawings
Accompanying drawing 2 is structural representations of cutter down of the present utility model;
Accompanying drawing 3 is user mode reference view of the present utility model.
Mark in the accompanying drawing is represented respectively:
1, upper slitter, 2, following cutter, 3, connector, 4, blade, 5, point of a knife, 6, the cutter groove.
The specific embodiment
Below in conjunction with accompanying drawing bending cutter of the present utility model is done following detailed description the in detail.
Shown in accompanying drawing 1,2, bending cutter of the present utility model, its structure comprises upper slitter 1 and following cutter 2, upper slitter 1 is connector 3 and blade 4 unitary whole structures, and blade 4 is inverted "L" shaped, 60 ° of blade 4 bent angles, the lower end of blade 4 is provided with the point of a knife 5 with the blade one, point of a knife 5 wedge angles are 90 °, and following cutter 2 is four-prism structures, wherein offer cutter groove 6 on continuous three faces in bottom surface top.Wherein, offer four cutter grooves on the upper surface of following cutter 2, the opening of four cutter grooves is 5mm, 8mm, 10mm, 6mm successively, and in the middle of wherein 8mm, 10mm groove were arranged on, 5mm, 6mm groove were arranged on both sides, and four cutter grooves are parallel to each other.The both sides of following cutter 2 upper surfaces respectively offer three cutter grooves on relative two surfaces, and in the middle of wherein big groove was arranged on, little groove was arranged on both sides.Left surface offers 12mm, 17mm and three cutter grooves of 9mm from top to bottom successively; Right flank offers 8mm, 20mm and three cutter grooves of 4mm from top to bottom successively; Three cutter grooves on left and right each side are parallel to each other.Cutter groove 6 cross sections are down equilateral right angled triangle.
This bending cutter has adopted good toughness aspect the material of selecting the bending cutter, the hardness height has the rapidoprint of the mould steel of stronger wearability as upper slitter.
