Abstract
The utility model relates to a bush punching die. A die base plate is fixedly arranged on a punch press workbench through a pressure plate with screws, and a lower die fixing plate is arranged on the base plate; a convex die plate is connected with a lower die fixing plate through pins, and a spring is arranged between the convex die plate and the lower die fixing plate; a hole is formed in the middle of the convex die plate, and the lower part of a stripper plate is connected with the spring through the hole in the middle of the convex die plate; a convex die is arranged on the convex die plate, and a die shank is clamped in a punch press nose; an upper die fixing plate is connected with the die shank, and a concave die is arranged below the upper die fixing plate; a die hole is formed in the middle of the concave die, and a stripper block is arranged in the die hole, is connected with a knockout bar in an upper die and is driven by the knockout bar to move. The stripper block and the knockout bar are arranged in the die hole of the concave die, so that a waste material in the hole is automatically pushed out after punching; the stripper plate is arranged in the convex die, so that a punched workpiece is lifted up to be conveniently taken down; the continuous punching can be carried out, so that the work efficiency is improved, and the safety of operation is also improved.
Description
Technical field
The utility model belongs to mould applications, is specifically related to a kind of lining punching die.
Background technology
Mould is the instrument for formed article, and this instrument has various parts to form, and different moulds is made up of different parts.It mainly realizes the processing of article profile by the change of institute's moulding material physical state.In stamping-out, shaping and punching, die forging, cold-heading, extruding, metallic sintered products compacting, compression casting, and in the compression moulding of goods such as engineering plastics, rubber, pottery or the shaping of injection moulding processing, there is the instrument of the product of given shape and size in order to make under external force blank become.Existing punching die impulse force in the time of punching is very large, and the waste material after punching is often filled in mould and is difficult for taking out, and causes ram efficiency low.
Utility model content
For solving the above-mentioned defect of prior art, the utility model relates to a kind of lining punching die, after punching, fertilizer can be discharged in mould.
The utility model is achieved through the following technical solutions:
A kind of lining punching die, comprise die, convex template, de-material piece, stripper plate, base plate, punch, work bench of punch press, base plate is screwed on work bench of punch press by pressing plate, counterdie fixed head is arranged on base plate, convex template is connected with counterdie fixed head by pin, between convex template and counterdie fixed head, spring is housed, convex template Intermediate Gray is porose, stripper plate bottom is connected with spring by the hole in the middle of convex template, punch is located on convex template, die shank is installed in punch press head, upper mould fixed plate is connected with die shank, die is arranged on upper mould fixed plate below, die middle part is provided with nib, in nib, be provided with de-material piece, de-material piece is connected and motion under knockout rod drives with the knockout rod being arranged in patrix, die setting corresponding to punch.
Described punch is provided with workpiece lining outward for fixation workpiece.
Described workpiece lining is ring assembling structure, and stripper plate top is arranged in the hole of encircling assembling device structure.
The center of described workpiece lining, punch, stripper plate, de-material piece, die point-blank.
The beneficial effects of the utility model: the utility model by arranging de-material piece and knockout rod in the nib of die, can after punching, automatically the waste material in hole be ejected, stripper plate is set in punch, workpiece after punching press can be lifted, conveniently take off workpiece, also can carry out continuous punching, improve operating efficiency, also improve the security of operation.
Brief description of the drawings
Fig. 1 is a kind of lining punching die structure figure.
Detailed description of the invention
A kind of lining punching die, comprise die 3, convex template 5, de-material piece 14, stripper plate 10, base plate 9, , punch 17, work bench of punch press 7, base plate 9 is fixed on work bench of punch press 7 by pressing plate 11 use screws 6, counterdie fixed head 12 is arranged on base plate 9, convex template 5 is connected with counterdie fixed head 12 by pin 13, between convex template 5 and counterdie fixed head 12, spring 8 is housed, convex template 5 Intermediate Grays are porose, stripper plate 10 bottoms are connected with spring 8 by the hole in the middle of convex template 5, convex template 5 tops are provided with punch 17, die shank 1 is installed in punch press head 15, upper mould fixed plate 2 is connected with die shank 1, die 3 is arranged on upper mould fixed plate 2 belows, die 3 middle parts are provided with nib, in nib, be provided with de-material piece 14, de-material piece 14 is connected and motion under knockout rod drives with the knockout rod 16 being arranged in patrix, die 3 setting corresponding to punch 17.
Described punch 17 is outer is provided with workpiece lining 4 for fixation workpiece.
Described workpiece lining 4 is ring assembling structure, and stripper plate 10 tops are arranged in the hole of encircling assembling device structure.
The center of described workpiece lining 4, stripper plate 14, de-material piece 10, die 3 point-blank.
Knockout rod is by external cylinder or drive link control.
When work, on die 3, put, punch 17 underlyings, are positioned over workpiece on punch 17 and fix with workpiece lining 4, along with punch press head 15 moves downward, drive die shank 1 downward, make the downward punching press of die 3; When die sinking resets, along with the elastic force effect of spring 8, jack-up convex template 5 inner strippers 10, lift workpiece; When upwards reset along with die 3, waste material enters in matrix cavity, and now, knockout rod 16 hits de-material piece 14, and waste material is come off in die 3, completes the punching of workpiece.
