Description
Technical field
The present invention relates to a kind of Ultrathin steel strip for punching continuous on Ultrathin steel strip and roll flushing device continuously.
Background technology
At present, the processing unit (plant) realizing continuous punching on sheet metal or band mainly has two kinds: a kind of conventional ones mould being mounted on forcing press, and another kind is to use punch roller and metal negative roller to cooperate the rolling hole punched device of composition.Wherein, conventional ones mould includes upper die and lower die, upper mold is by die shank, upper bolster, punch, punch retainer, stripper and guide pin bushing etc. form, lower mold is by die, die shoe and guide pillar etc. form, during production, mould is arranged on universal press or high-speed blanking press, pass through uncoiler, levelling machine, plate is sent to mould and carries out punch process by servo feeding mechanisms etc., on the one hand, owing to Ultrathin steel strip is the thinnest, punch and die gap are the least, difficulty of processing is big, on the other hand, due to stripper continuous repeated stock Ultrathin steel strip, easily make strip deformation, thus produce the bad defects such as banding ripple, product is caused to can not meet use requirement.And roll in hole punched device, it is to be provided with metal die block uniformly at the surface perimeter of punch roller, the metal covering that die roller is corresponding is provided with die hole, sheet metal or band pass through between punch roller and die roller, punch roller and die roller are in relative rotational motion, and convex module inserts in corresponding die hole and realizes the continuous punching on sheet material or band.The defect of this continuous punching device being made up of punch roller and die roller is: 1., the quality of fit of convex module and die hole be highly susceptible to the impact of the abrasion of part in drive mechanism; thus it is frequently necessary to shut down and the wearing part of drive mechanism is replaced and punch roller and die roller are accurately adjusted in the position in axial and circumference, the maintenance cost causing equipment is higher, production efficiency reduces；2., this continuous punching device the most often occur punched under metal debris be stuck in die hole in the phenomenon that cannot deviate from; must shut down and manually choose; otherwise too much can block die hole owing to metal debris accumulates in die hole, the equipment that affects runs well；3., owing to requiring higher to the installation of convex module and die hole and quality of fit, the processing cost causing punch roller and die roller is higher, and equipment debugging is the most difficult, and equipment investment is bigger；4., convex module coordinate with die hole, while punching, the sheet material passed through or band produced extruding, be easily deformed when the sheet material passed through or band are relatively thin, affect product quality.
Summary of the invention
It is an object of the invention to: provide a kind of Ultrathin steel strip to roll flushing device continuously, to solve the problem that existing continuous punching device maintenance cost is high, production efficiency is low, equipment investment is big.
The technical scheme is that a kind of Ultrathin steel strip rolls flushing device continuously, described rolling flushing device has upper die and the lower die that a pair rolling coordinates, described upper die and lower die include the center base roller of pair of parallel setting, outside two center base rollers, all it is coated with packing element composition covers rubber roll, the peripheral circumferentially uniform metal core rod being radially installed with some columns of the center base roller of die on described, the outer face of each cylindrical metal core rod flushes with the outer surface of corresponding packing element.
The inner face top of described cylindrical metal core rod is contained in the Ji Gun surface, center of die or is inserted in the blind hole that Ji Gun surface, the center correspondence of die is offered or spinning is in the screwed hole that Ji Gun surface, the center correspondence of upper die is offered.
nullIt is that in utilizing upper die packing element, the metal core rod of installation realizes the continuous punching on Ultrathin steel strip with the resilient engagement of lower die surface glue cylinder that the Ultrathin steel strip of the present invention rolls flushing device continuously，Due to upper、Lower die all have employed covers rubber roll structure，Thus without arranging convex module and the die hole of corresponding matching in two die，The production cost of equipment is not only greatly reduced，Also the drive mechanism parts depreciation impact on two die quality of fits is solved，Thus effectively reduce the maintenance cost of equipment，Improve the production efficiency of equipment，And，Two cover rubber roll rolling be press-fitted in realize continuous punching while effectively avoided the crimp of Ultrathin steel strip by surface coated packing element，Improve the flatness of steel band，Simultaneously，Lower die uses the ganoid rubber roll that covers that metal debris can be avoided at lower die superficial residence，Realize automatic discharging，Thus efficiently solve the problem that in prior art, metal debris easily blocks die hole.
Accompanying drawing explanation
Fig. 1 is the structural representation that Ultrathin steel strip of the present invention rolls flushing device specific embodiment continuously；
Fig. 2 is the use state stereogram that Ultrathin steel strip of the present invention rolls flushing device continuously.
Detailed description of the invention
The Ultrathin steel strip of the present invention rolls the specific embodiment of flushing device as shown in Figure 1 and Figure 2 continuously, and it has upper die 1 and the lower die 2 that a pair rolling coordinates, and on this, die 1 and lower die 2 are and cover rubber roll.Wherein, upper die 1 includes center base roller 10, on this, center base roller 10 periphery is radially arranged the metal core rod 12 of some columns the most uniformly, Bing Shang center base roller 10 is outer is coated with packing element 11 on a circle uniformly, each cylindrical metal core rod 12 is fixed on this in packing element 11, the outer face of each cylindrical metal core rod 12 flushes with the outer plate surface of upper packing element 11, and the inner face top of each cylindrical metal core rod 12 is contained on the surface of center base roller 10.Lower die 2 Shi Youxia center base roller 20 and the lower rubber cylinder 21 being evenly coated at outside lower center base roller 20 are constituted.Upper die 1 be arranged in parallel with lower die 2, Ultrathin steel strip 3 passes through between upper die 1 and lower die 2, it is deformed owing to the upper packing element 11 of upper die 1 mutually extrudes with the lower rubber cylinder 21 of lower die 2, so that the lower rubber cylinder 21 on the built-in cylindrical metal core rod 12 of upper die 1 and lower die 2 surface extrudes, coordinate and realize continuous punching on Ultrathin steel strip 3.
The Ultrathin steel strip of the present invention rolls the feature of flushing device continuously: the rolling 1., by a pair covering rubber roll coordinates, Ultrathin steel strip between making by two rollers is in triaxial stress state all the time, thus avoid Ultrathin steel strip and be squeezed and deform, improve the flatness of Ultrathin steel strip after punching, thus improve the quality of product；2., this Ultrathin steel strip roll continuously flushing device lower die use the ganoid cylindrical metal core rod covering rubber roll built-in with upper die packing element coordinate, the elasticity that can utilize packing element realizes the automatic discharging of metal debris, efficiently solve metal debris in prior art and easily block the problem of die hole, improve the dependability of equipment；3., upper and lower die all uses and covers rubber roll and reduce the difficulty of processing of die, thus effectively reduces the manufacturing cost of equipment；4., upper and lower die all use and cover rubber roll and also efficiently solve prior art convexity module and coordinate with die hole and easily affected problem by drive mechanism parts depreciation, thus be effectively reduced outage rate, reduce the maintenance cost of equipment.
The present invention is not limited to above-described embodiment; in a particular application; each cylindrical metal core rod can also be inserted in the blind hole that Ji Gun surface, center correspondence is offered or spinning is in the screwed hole that Ji Gun surface, upper center correspondence is offered, and it is all within protection scope of the present invention.
