Abstract
The utility model discloses a cutting blade for precision rubber preformers, which comprises a blade body, one side face of the blade body is provided with a first inclined surface, and a position, opposite to the first inclined surface, on the other side face of the blade body is provided with a second inclined surface. The cutting blade disclosed by the utility model has the beneficial effects that the structure design of a tool point is elaborate, so that the stress state of a tool is good, the lateral loads of the two sides of the tool can be mutually cancelled out, and the service life of the tool can be prolonged by more than five times; and meanwhile, an operation of tool sharpening can be avoided, thereby reducing the labor intensity of operators, improving the labor productivity, saving the energy and reducing the operating cost.
Description
Technical field
The utility model relates to a kind of cutting blade that is used for the accurate preforming machine of rubber.
Background technology
Rubber is all processed through multiple working procedure by natural rubber or synthetic rubber, and wherein one important procedure is exactly preformed.The blade of the rotary-type shearing of preforming machine commonly used is the single-blade face at present; That is to say that cutting blade has only an inclined plane; Because cutting blade rotary speed when shearing is exceedingly fast, moment accomplishes and shears, and on the single-blade face, can produce bigger lateral load; Again because in order to guarantee that the shearing quality cutting blade need remain on the distance of 0.1mm to 0.2mm with die head; The knife edge portion mechanical strength of outstanding knife rest is the weakest, so the knife edge portion of cutting blade can produce distortion inevitably under the effect of lateral load, after deflection meets or exceeds the spacing between cutting blade and the die head, can wipe mutually with die head and bump and damage.
Summary of the invention
For overcoming above-mentioned defective; The utility model technical issues that need to address are: provide a kind of and can improve the mechanical strength force-bearing situation of weak knife edge portion the most; Guarantee that cutting blade can not produce distortion, thus the cutting blade that is used for the accurate preforming machine of rubber that prolongs its service life.
The utility model solves the in-problem technical scheme of prior art: a kind of cutting blade that is used for the accurate preforming machine of rubber; Comprise cutter hub; One side of cutter hub has first inclined plane, and the another side of said cutter hub is provided with second inclined plane in relative position, first inclined plane.The knife edge cross section of cutting blade is approximate isoceles triangle shape like this; During shearing, the lateral load that knife edge portion produces on first inclined plane and second inclined plane is in the opposite direction, and size is close; Can cancel each other; And the ability that isosceles triangle bears lateral load will be superior to right angled triangle greatly, makes knife edge portion can not produce distortion, guarantees the service life that cutting blade is long; In addition, because knife edge cross section is approximate isoceles triangle shape, during shearing; The wearing and tearing that occur on first inclined plane and second inclined plane are superimposed faster than the rate of wear of the knife edge; Make that cutting blade need not to whet a knife, remain sharp state, save the shutdown tool changing; Can reduce operating personnel's labour intensity like this, raise labour productivity.
The folded angle in the another side of said second inclined plane and cutter hub is 12 ° to 20 °; The width on second inclined plane is 0.2mm to 1.5mm.Second inclined plane can solve cutting blade problem on deformation and knife edge rust problem preferably by such angular range and width range setting.
The folded angle in the another side of said second inclined plane and cutter hub is 16.7 °; The width on second inclined plane is 1mm.Guaranteeing that cutting blade has under the situation of enough resistance change mechanical strengths, make the cutting blade knife edge be in the sharpest state like this, reduce shearing resistance, reduce energy resource consumption, practice thrift operating cost.
The knife edge included angle that forms between said first inclined plane and second inclined plane is 30 ° to 40 °; The width on first inclined plane is 3mm to 7mm.
The knife edge included angle that forms between said first inclined plane and second inclined plane is 35.7 °; The width on first inclined plane is 5mm.
Said cutter hub is provided with " U " v notch v, and the openend of " U " v notch v deviates from the blade direction of cutter hub.The setting of " U " v notch v can make things convenient for the installation and the adjusting of cutter hub.
The quantity of said " U " v notch v is two.
The beneficial effect of the utility model is: knife edge structural design is exquisite, makes that the stress of cutter is good, and the lateral load of both sides can be cancelled each other, and can prolong the service life of cutter more than five times; Simultaneously can exempt sharpening work, reduce operating personnel's labour intensity, improve labor productivity, energy savings reduces operating cost.

The specific embodiment
Pass through specific embodiment below, and combine Figure of description that the technical scheme of the utility model is further specified:
Embodiment: a kind of cutting blade such as Fig. 1, shown in Figure 2 that is used for the accurate preforming machine of rubber; Comprise that thickness is the cutter hub 1 of 1.7mm; One side 5 of cutter hub 1 is provided with first inclined plane 4, and the another side 2 of cutter hub 1 is provided with second inclined plane 3 in 4 relative positions, first inclined plane; Second inclined plane 3 is 16.7 ° with the another side 2 folded angle of cutter hub 1, and the width M on second inclined plane 3 is 1mm; The knife edge included angle β that forms between first inclined plane 4 and second inclined plane 3 is 35.7 °; The width N on first inclined plane 4 is 5mm.As shown in Figure 3, cutter hub 1 is provided with two " U " v notch vs 6, and the openend of " U " v notch v 6 deviates from the blade direction of cutter hub 1.
Above-described embodiment is a kind of preferred version of the utility model, is not the utility model is done any pro forma restriction, under the prerequisite that does not exceed the technical scheme that claim puts down in writing, also has other variant and remodeling.
Make the content of detailed description in this specification, belong to the those skilled in the art known prior art.
