Description

For double hardness cushion rubbers that strip cuts
Technical field
The utility model is related to a kind of double hardness cushion rubbers cut for strip, is mainly used in metal processing sectors.
Background technology
With the fast development of national economy, sheet metal cuts and is played an important role in metal processing sectors, and In the slitting cutting mechanism of the sheet metals such as copper, aluminium, stainless steel, it will usually use cushion rubber.Such as Chinese patent CN201320567075.9, is related to copper and copper alloy belt cutting process, specially a kind of to be applied to cutting for copper and copper alloy belt Device.Solve the technical problem that difficulty is cut when cutting the less copper of thicker and flakiness ratio and copper alloy belt at present.One kind should For copper and the cutting means of copper alloy belt, it is included in upper and lower axle and is respectively provided with the equal round sword of multiple number same diameters and cuts Blade, the blade on blade and lower axle on the upper axle is in the gesture of upper and lower alternating packets appearance, between the adjacent knife blades on each axle Interval be also that size is alternately arranged;Axle cutter is spaced big position and is provided with the first compounded rubber circle, the small position of blade clearance Metal distance collar is installed.The utility model simple structure, effectively reduces shearing force, reduces work difficulty;Reduce multiple The quantity of rubber ring is closed, using robust metal distance collar, manufacturing cost is reduced.Blade is changed to single dege blade, effectively Solve knife line scratch problem.
As shown in the basic composition schematic diagram of Fig. 2 sheet metal slitting cuttings mechanism, there be cushion rubber 1 ' when sheet metal cuts Hereinafter act on:
1)The shearing of blade is balanced as the chopping block of blade when cutting;The only very strong slab of rigidity, or hardness is very Thin plate high, does not use otherwise cushion rubber 1 ' that the lath transverse shape of whole thin plate can be caused uncontrollable, becomes pole out-of-flatness;
2)Using the mutual pressure of upper and lower cushion rubber 1 ', frictional force is produced on plate, pushed away before help plate and divided by shear zone Bar cuts;
3)More cylindrical than dise knife 3 ' bigger using the diameter of male knife side cushion rubber 11 ', female knife side 12 ' diameters of cushion rubber are more cylindrical than dise knife 3 ' Smaller characteristic, makes plate have individual to the minute movement in female knife side in vertical direction, so as to allow the strip for shearing to depart from as early as possible Shear zone, prevents edge from being wiped by blade and touches and produce small gap.
But the common fault in a kind of quality can be all encountered during cutting:That is plate after slitting, all can by strip both sides There is the existing picture of flange.In the cutting of soft plate, flange is existing as especially serious, its transverse shape such as Fig. 3 after flange Shown in flange phenomenon schematic diagram after sheet metal slitting cutting.
The principle schematic institute of sheet material flange is caused such as the typical cutting mechanism male and female knife side arrangement schematic diagrames of Fig. 4 and Fig. 5 Show, sheet material 4 ' produce flange the reason for be the inadequate natural endowment in the fabrication process of cushion rubber 1 ':
1)For cushion rubber 1 ', middle part is entirety, but both sides the corner of cushion rubber 1 ' because foreign object is without support, its rigidity Naturally it is deteriorated;
2)In order to ensure that cushion rubber 12 ' is flexible, either Composite rubber-ring or loose cushion rubber, its width is generally than left and right two Spacing between piece knife 3 ' is small, and left and right two sides will reserve 0.1-0.2 millimeters of space 5 '.And exactly this space 5 ', The space made a concession is provided to the corner of cushion rubber 12 ';
3)Because the surface accuracy of cushion rubber 1 ' can not possibly be made as iron core is so accurate, glue surface 1 ' must also compare iron core Plane is low 0.1-0.2 millimeters, to avoid producing interference to dress knife precision and influence;Just due to this 0.1-0.2 millimeters of gap 5 ', Rigidity along with the corner of cushion rubber 12 ' is very poor, so as to the due rigidity of chopping block institute not having in ideal, in the shearing of blade 3 ' Under effect, the corner of cushion rubber 12 ' will produce and collapse, so as to thin but also soft plate 4 ' may be made not only to be produced in its both sides turn over Side.
Flange this quality problems are solved, inventor contemplates many methods in real work:
1)The surface accuracy of cushion rubber 1 ' is such as improved, to reduce recessed amount and cushion rubber 1 ' Zuo You two of the cushion rubber 1 ' to iron core plane The space 5 ' on side, enable the side of cushion rubber 1 ' in stress against knife face to increase the corner of cushion rubber 1 ' rigidity.But in reality, this meeting Production cost is significantly increased, and reduces the elasticity of cushion rubber 1 '.
2)The hardness of cushion rubber 1 ' is such as improved, the deformation of the corner of cushion rubber 1 ' is reduced, but too high hardness can make cushion rubber 1 ' in zone face On leave rubber print.And cushion rubber 1 ' really up to the mark loses elasticity, the lap for making shearing needs bigger, excessive lap is again Make the stress of cutter shaft 21 ', 22 ' excessive, deformation increases, the situation in the middle of cutter shaft 21 ', 22 ' with edge shearing is inconsistent, so as to produce A series of problems.
As shown in Fig. 6 traditional double hardness cushion rubber schematic diagrames, external cutter manufacture manufacturer devises to solve this problem A kind of pair of hardness cushion rubber 1 ' ':The hardness of outer layer cushion rubber 11 ' ' is high, reaches Shao90, and the hardness of internal layer cushion rubber 12 ' ' is low, is Shao75.For example same Double-layer cushion of this structure, upper strata is hard, and lower floor is soft, and overall still flexible.Such as Fig. 7 traditional double hardness Cushion rubber is cut shown in schematic diagram, and such a configuration obviates list with a kind of high rigidity, or a kind of low hardness apron 1 ' is brought Problem, has reached cushion rubber 1 ' ' outer layer is hard, corner is rigidly good, strip not easy flanging, and internal layer is flexible, can effectively achieve by Strip 4 ' ejects the purpose of shear zone, it is achieved thereby that the high unity of contradiction.
But the shortcoming of the method is exactly big manufacture difficulty, and expense is expensive, its price is 4 times of common single hardness cushion rubber 1 ', Many clients cannot receive, thus in Chinese market few this pair of hardness cushion rubbers 1 ' ' user and producer.
Inventor by continuously attempting to and study at work, there is provided one kind makes simple, with low cost for plate Double hardness cushion rubbers that band cuts, while avoiding single with a kind of high rigidity, or the problem that a kind of low hardness apron is brought.
