Description
Technical field
The utility model belongs to the hardware ﹠ tools field, relates to a kind of cutter sweep of high polymer material, especially a kind of cutter sweep of polyurethane.
Background technology
At present, stamping factory mould workshop section uses the frequency of polyurethane higher, need in use polyurethane cut off and satisfy actual requirement, this action need workman finishes with instrument, present stage is generally all adopted the saw cutter, but polyurethane has high resiliency, require great effort very much during manually-operated, and, saw out shape and also often do not reach requirement, sawed the also out-of-flatness of back section, form the vestige that a lot of sawtooth stays, can not directly in next process, use, also need it is further processed or repairs, greatly reduce operating efficiency and work quality like this, and saw time, be constantly polyurethane to be rubbed, be easy to generate more chip, can waste more material.
Summary of the invention
The utility model has solved in the prior art cutting polyurethane and has adopted the saw cutter to waste time and energy, and the arrive shortcoming of requirement of shape after saw, and a kind of cutting that is specifically designed to quick polyurethane one class high polymer is provided, and the cutting profile cutter sweep that can meet the demands.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of polyurethane cutter sweep, be arranged on the base, comprise patrix cutter piece and lower die cutter piece, the lower die cutter piece is provided with all and isolates seam, the blade of patrix cutter piece is over against the cutting crack, and patrix cutter piece is hingedly fixed on the handle connecting device and can rotates in the plane at cutting place, crack.The lower die cutter piece is fixed, the rotation of patrix cutter piece, polyurethane is placed on the lower die cutter piece, the extension position of cutting is at the blade place of patrix cutter piece, behind the patrix cutter piece rotation cutting polyurethane, blade is cut into the cutting crack of lower die cutter piece, thereby polyurethane is cut off, and the cutting end face of polyurethane also keeps smooth.
The placed side of lower die cutter piece is a circular arc, and the dual-side height of lower die cutter piece is middle low.The arc-shaped structure of lower die cutter piece can play the effect of location to polyurethane, prevents that polyurethane from moving when cutting, causes the cutting position instability, and the cutting section out-of-flatness makes whole shape not reach requirement.
Fixedly on the counterdie fixed head, the lower die cutter piece is fixed on the counterdie fixed head handle connecting device, and the counterdie fixed head is fixed on the base.Patrix cutter piece is fixed on the handle connecting device, and handle apparatus and lower die cutter piece are fixed on the counterdie fixed head simultaneously, guarantees that like this position of rotation of patrix cutter piece and lower die cutter piece remain unchanged.
Be fixed with spring on the base, the Plane of rotation of spring and patrix cutter piece is on same plane, and the position of the handle of patrix cutter piece aligns the spring that is fixed on the base.When the blade of patrix cutter piece entered into the cutting crack of lower die cutter piece, spring was compressed, and produced elastic force, the direction of elastic force upwards, and is identical with the gyratory directions of patrix cutter piece, and booster action is played in revolution to patrix cutter piece like this, conveniently unclamp patrix cutter piece, thereby reduce operator's labour intensity.
For reduce the operator firmly, thereby increase the moment of cutting by the mode that enlarges the arm of force, the boosting-rod that an end of patrix cutter piece is provided with cutter piece handle and extends from cutter piece handle, the other end of patrix cutter piece is provided with circular hole.
The handle connecting device middle is provided with a groove, and two cell walls are provided with two coaxial circular holes, are installed with connecting screw in the circular hole, and connecting screw is passed the circular hole of patrix cutter piece and patrix cutter piece is fixed on the handle connecting device.
Patrix cutter piece is the acute angle blade towards a side of lower die cutter piece, and described acute angle is 20 °-30 °, and the two sides of blade are for facing directly, and the body two sides of patrix cutter piece are the acute angle that is less than knife edge angular.Polyurethane has higher elasticity, can faster finish cutting by suitable less acute angle blade, and for the polyurethane end face that prevents to sever compresses patrix cutter piece, the angle of patrix cutter block body is less than the angle of blade.
The length of the blade of patrix cutter piece is greater than the width of lower die cutter piece.
The beneficial effects of the utility model are: by the acute angle blade polyurethane is cut, can guarantee that cutting profile meets the requirements, the section of cutting is smooth, saved the operation of then repairing, improved efficient, the arc placed side of lower die cutter piece can position polyurethane, can not move during cutting, guarantee the precision of cutting, combine with handle, save operator's muscle power by boosting-rod, on base, fix a spring, after having cut, the elastic force of generation can impel patrix cutter block reset, has reduced operator's labour intensity.
