Abstract

The utility model provides a die cutting device of a crank press. A punch is arranged on a cantilever [4] extended from a mainbody [1] in the direction of a punching die. A pillow part is arranged on the base extended from the mainbody in the direction of the punching die. The cantilever and the base are supported by a cantilever upright column [2]. An upper die and a lower die are arranged on the punch and on the pillow part. The die comprises an annular blanking knife [11, 12] and a line shear knife [16, 17, 19, 20], wherein the installation device of the line shear knife is at one side of the blanking knife facing the cantilever upright column and the cut line formed by the incision of the line shear knife perforates the connection part on the waste material to make the waste material is gradually cut up and got rid of during operation. When another line of lid is punched down, the former line of the waste material is annihilated to shorten the width between the sheet bar strike area and the cantilever upright column and to make the sheet bar feed more in the direction of the upright column, accordingly the sheet bars with different width can be used on the crank press with smaller cantilever length.

Description

The blanking units of crank press
Technical field the utility model relates to a kind of blanking units of crank press, belongs to the metalworking technology field.
The background technology crank press is the equipment that is usually used in making food product packets tinning upper and lower covers, and operating process is need use iron sheet at iron sheet upper punch lower cover, i.e. blanking, and can extrude annular groove simultaneously on demand, circular lid and square lid etc. are arranged.The blanking units of crank press is the mechanism that implements die-cut blanking, stamps out operations such as annular groove, wherein drift is installed in fuselage on the cantilever that the stamping die direction stretches out through guide rail, and bolster portion is installed in fuselage and stretches on the base that direction stretches out to stamping die equally.The mould up and down that the blanking units of crank press in the past, its stamping die only are mounted in drift and bolster portion is a pair of or some to becoming one group the blanking die that comprises the pressure ring channel mould, and the combination of the mould of the endless knife of die-cut lid material and compacting annular groove is promptly only arranged.This decompressor when implementing punching operation, the plate of accepting punching press after being cut off lid material part, surplus waste material still join together by the part that is not cut off, promptly the width of plate still keeps original width.Plate on the open market is a broad, as carrying out punching operation to this plate outermost, just need cantilever that enough length is arranged so that the iron sheet inboard is not kept off by the column of fuselage upper support crank mechanism and cantilever, otherwise will make decompressor reach the iron sheet outside.But limit by machine cost and material behavior, crank press from the column of supporting cantilever to cantilever on length the stamping die centre of percussion, it is very long to be that jib-length can not make, this carries out punching operation after just causing plate will be cut into fillet earlier, thereby cause the waste in material and man-hour, increased the manufacturing cost of food product packets tinning.Change continually simultaneously and pull material, also cause the further raising of cost.
Summary of the invention is at above-mentioned defective, and technical problem to be solved in the utility model is to transform the blanking units of crank press, so that a kind of blanking units that reduces the crank press of food product packets tinning manufacturing cost to be provided.
The blanking units of the crank press that the utility model provides, drift is installed in fuselage on the cantilever that the stamping die direction stretches out through guide rail, bolster portion is installed in fuselage on the support that the stamping die direction stretches out, cantilever and support are with the cantilever upright supports, mould is installed in drift and the bolster portion up and down, the blanking cutter that comprises annular in the mould, also comprise the lines shear knife up and down in the mould, the installation site of lines shear knife is in the side of blanking cutter to the cantilever column, and the formed line of cut of the lines shear knife edge of a knife connects the coupling part on the waste material.
The blanking units of the crank press that the utility model provides, said its shear line of lines shear knife can be designed to different shape and direction, but must be to connect the coupling part between the material-dropping hole on the waste material.From angle design simply and easily, can be designed to be parallel to the cross-wise lines shear knife of plate moving direction and the locational vertical lines shear knife of the convergence centre of percussion when plate moves, make in blanking, cross-wise lines shear knife and the longitudinal shear cutter block-by-block that matches cuts off the waste material of the centre of percussion to cantilever column one side.
The blanking units of the crank press that the utility model provides, the horizontal shear knife of a slice and two shear knife is longitudinally arranged in the mould, shear knife is linear, horizontal shear knife is in the side of blanking cutter to the cantilever column, shear knife, and divides in the blanking cutter left and right sides again to a side of cantilever column at horizontal shear knife longitudinally; From plate upper punch hole site, horizontal lines shear knife connects near the vertical coupling part between punching and the hole in the delegation of endless knife, and the lines shear knife connects near delegation of endless knife punching and the lastrow horizontal coupling part between punching more longitudinally.When punching operation, plate with about the mode of back and forth advancing line by line accept punching press.No matter exactly set up two longitudinally the purpose of shear knife make plate turn left or turn right and advance, always there is a slice longitudinal shear cutter coupling part that the waste material that enters Stamping Area on the plate is horizontal to cut off, waste material is shredded and cooperate with horizontal shear knife.
The blanking units of the crank press that the utility model provides, the guide rail that drift is connected with fuselage tilts, the plane of counterdie is installed on the pillow-cushion part, be that the charging plane then is the inclined plane vertical with guide rail, the cantilever column is below the charging plane, a finished product output bucket is being installed between the mould up and down, the plane of on finished product output bucket and the pillow-cushion part counterdie being installed, be that a charging gap greater than sheet thickness is arranged between the charging plane, on the upper and lower mould closed position, leave the hole, wherein the blanking cutter position leaves the hole greater than the blanking cutter, and finished product output bucket downside has an outlet to guide the finished product collecting box into.After die-cut operation was finished, finished product was enclosed within on the patrix, and resetting at drift is with push rod finished product to be taken off from patrix.At this, pass through to the hole of when drift resets finished product being stayed from finished product output bucket and reach product output bucket top, utilize the vertical drop after finished product is taken off from patrix again, make it avoid the hole of being stayed on the finished product output bucket and drop on the bucket end and slide to outlet and fall in the finished product collecting box.This structure makes finished product be moved apart the punching operation district in time and is collected, and has guaranteed that big plate is not subjected to the influence of finished product discharging speed in the high speed stamping operation.
The blanking units of the crank press that the utility model provides, be provided with in order to cut off the lines shear knife of coupling part on the waste part in the side of blanking cutter to the cantilever column, make progressively chopping eliminating of waste material quilt when operation, after another capable lid is stamped down, the waste material of previous row is all wiped out, thereby dwindled the width between plate strike zone and the cantilever column, plate can further be sent into to the column direction, thereby how wide plate all can be used on the crank press of less jib-length.
