Abstract
The present invention relates to a kind of aperture knife tool of elastomeric material, including cylindric hollow cylinder, it is columnar blade at the lower ending opening of cylinder, it is wedge shaped on the inside of blade, blade lateral surface is vertical cylinder face, cylinder upper-center is provided with the chuck being connected with drill chuck, and passage is offered on the cylinder of chuck both sides.The beneficial effects of the invention are as follows：Manufacture and design simply, cost is low, easy to use.
Description
Technical field
The present invention relates to a kind of aperture knife tool of elastomeric material.
Background technology
Motorcycle, automobile engine manufacturing process in, air-leakage test be together highly important process.Polyurethane
Rubber because it is flexible big, tensile strength is high, wearability is good, oil resistant the features such as and be often selected as gas inspection gasket material, and gather
The quality of urethane rubber slab crudy will directly influence the accuracy of gas inspection.
Polyurethane rubber seal pad used in certain model motorcycle cylinder body air-leakage test, it is desirable to processing one thereon directly
Footpath 56mm macropore, a width are 14mm elongated hole and 6 diameter 10mm aperture.Past uses fluted drill machining small, and
Blade cutting macropore or the countersink with the processing metallic plate of cylindrical strip sawtooth process macropore by hand, and processing efficiency is low,
Circular hole is non-round, and side mouth is uneven, and production quality is difficult to reach requirement, and quality accident occurs when frequently resulting in detection.It is close to solve this
The processing problem of packing, devise the circular dedicated tool of special continuous side mouth.
The content of the invention
The technical problem to be solved in the present invention is：Based on above mentioned problem, there is provided a kind of aperture knife tool of elastomeric material.
The technical solution adopted for the present invention to solve the technical problems is：A kind of aperture knife tool of elastomeric material, including
Cylindric hollow cylinder, be columnar blade at the lower ending opening of cylinder, blade inner side is wedge shaped, and blade lateral surface is vertical
Straight cylindrical surfaces, cylinder upper-center are provided with the chuck being connected with drill chuck, passage are offered on the cylinder of chuck both sides.
Further, the material of cylinder is 45 steel.
Further, the angle of blade wedge shape is 5~30 °.
The beneficial effects of the invention are as follows：Manufacture and design simply, cost is low, easy to use.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Wherein：1. cylinder, 2. blades, 3. chucks, 4. passages.
Embodiment
Presently in connection with accompanying drawing, the present invention is further illustrated.These accompanying drawings are simplified schematic diagram only with signal side
Formula illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
A kind of aperture knife tool of elastomeric material as shown in Figure 1, including cylindric hollow cylinder 1, the lower end of cylinder 1
Opening is columnar blade 2, and the inner side of blade 2 is wedge shaped, and the lateral surface of blade 2 is vertical cylinder face, and the upper-center of cylinder 1 is set
There is the chuck 3 being connected with drill chuck, passage 4 is offered on the cylinder 1 of the both sides of chuck 3.
The angle of the wedge shape of blade 2 is 5~30 °
Cutter section cutting edge is wedge shaped, and processed rubber plate thickness is bigger, and key groove is smaller；It is straight on cutter external cylindrical surface
Line, to ensure to process the dimensional accuracy of bore dia；Cutter top is provided with four passages, is not only convenient for the rubber that will cut from knife
Excluded in tool and (ejected with thin bar or blown out with compressed air), can also mitigate cutter deadweight.The main points of design are wedge-shaped working edges
Mouth must be continuous circular arc, rather than be split into zigzag as processing the countersink of metal.
The optional scope of the dedicated tool material is very big, and nearly all ferrous metal all can be selected, and 45 steel costs are minimum
And it is easily worked.The cutter larger to processing capacity, selective hardening must be carried out to the edge of a knife.The processing of cutter is equal on lathe and drilling machine
Can carry out.It is required that the processing roughness of cutter outer round surface and internal conical surface is as low as possible, preferably on lathe hand polish with
Improve surface roughness precision.
The processing of rubber gasket can be implemented on common bench drill using the dedicated tool：Workpiece is suitably compressed, is
Cutting edge is protected, chock plate or annular groove space must be reserved under rubber slab workpiece, the edge of a knife is collided with hard thing during preventing that rubber slab from cutting through；
To improve cutter life, processing district can be suitably added suds or machinery oil implements lubrication.
Actual use shows, is needed 10 seconds using tool sharpening diameter 56mm hole；It is neat to be processed hole side mouth, it is coarse
Spend for 2.0~3.0 μm；10 workpiece are surveyed, average pore size is diameter 56.2mm.Using the dedicated tool machining accuracy and synthesis
Quality is high.
The design and manufacture of the cutter are simple, and cost is low, can also processing leather, cardboard, plastics in addition to for processing rubber plate
Thin plate (piece), cloth, asbestos, sponge etc..
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
