Abstract

The utility model discloses a paper punching die used in printing machine comprising an upper die, a drift punch and a lower die. The lower die is a female die with a punching. The upper die and the drift punch assembly are connected via a bearing to form a male die. A bolt wrings the drift punch directly and fixes a chuck of the upper die to form a drift punch assembly. The drift punch adopts the metal material with low intensity and good toughness. The size of the drift punch is 0.01-0.02mm bigger than the size of the drift hole of the lower die. The beneficial effects of the paper punching die used in printing machine are convenient operation, long service life and high accuracy. The paper punching die used in printing machine can save producing time and increase producing efficiency.

Description

Be used for the paper punching die on the printing machine
Technical field
The utility model relates to a kind of paper punching die, especially is the paper punching die on the printing machine of being used for of the supporting punching frock of record-paper printing processing machine.
Background technology
The paper punching die is the one group of parts that aims at the paper punching on the printing machine, and power is done in opposite directions upper and lower axle and rotated by gear drive, drives upper and lower mould and rotates.When paper by between the upper and lower mould time, finish punching by the matched moulds of upper and lower mould to paper.General upward axle is a moving axis, upper and lower mould is thrown off its rise, and upper and lower mould can be loaded and unloaded.
As shown in Figure 1, the drift 3 of the punching die that is used for the record-paper punching of prior art is contained in mould, be punch, drift 3 adopts high strength, high rigidity metal material, steel band 6 is contained in down on the mould, be die, high-strength steel strip during steel band 6 adopts is finished punching to paper by the drift 3 and the matched moulds of steel band 6.
Because the step pitch between the Kong Yukong on the steel band 6 is that the conversion by pitch forms on punch press, makes circle by artificial riveting again, the cumulative errors of general step pitch can reach 0.70~0.90mm, and artificial riveting system can make the steel band hole at circumferential not coplanar again.These reasons cause the steel band life-span in use very short, and the existence of accumulated error also causes the wearing and tearing of drift to be accelerated.Shown in Fig. 2,3, because drift is totally to be installed by last mould, promptly between per 2 drifts 3,1 construction bolt 9 is arranged, drift 3 is pressed on the patrix chuck, when changing drift 3, all bolts 9 be unclamped, could change drift.All to go up grinding machine so change drift at every turn, to guarantee the same circularity of drift cylindrical.In use precision is not high, inconvenient operation, and the life-span is shorter.
Summary of the invention
In order to address the above problem, it is a kind of by the band steel structure form being improved to the form of whole steel ring punching bed die that the utility model provides, and improved the paper punching die on the printing machine of being used for of punching precision.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of paper punching die that is used on the printing machine, comprise patrix, drift, counterdie, and counterdie has the die of punching above being; Patrix is connected by bearing with punch-head assembly, forms punch; Bolt directly screws drift and the patrix chuck is fixed and is formed punch-head assembly.
What described drift adopted is the metal material of low-intensity, good toughness.
The size of described drift is than the big 0.01-0.02mm of size of counterdie punching.
The beneficial effects of the utility model are: easy to operate, and long service life, the machining accuracy height is saved and is produced man-hour, enhances productivity.

Among the figure: 1, go up axle; 2, patrix; 3, drift; 4, lower shaft; 5, counterdie; 6, band steel; 7, bearing; 8, punching; 9, bolt; 10, patrix chuck; 11, bolt; 12, drift.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the paper punching die that is used on the printing machine of the present utility model is described in further detail:
Shown in Fig. 4,5,6, the structure that is used for the paper punching die on the printing machine of the present utility model is: counterdie 5 has the die of punching 8 above being, patrix 2 is connected by bearing 7 with drift 12 assemblies, form punch, directly screw drift 12 with patrix chuck 10 fixing drift 12 assemblies that form by bolt 11.
What described drift 12 was adopted is the metal material of low-intensity, good toughness.
The size of described drift 12 is than the big 0.01-0.02mm of size of counterdie punching 8.
In sum, paper punching die of the present invention, at first, cancelled steel band, utilize machining center directly punching 8 to be got on counterdie 5, the step pitch accumulated error that punching 8 and punching are 8 can be accurate to 0.3~0.5mm, has also guaranteed the problem of punching 8 at circumferential not coplanar simultaneously; Secondly, drift 12 adopts the metal material of low-intensity good toughness, and counterdie 5 adopts high strength, high rigidity metal material, drift 12 overall sizes are than the punching 8 big 0.01~0.02mm of counterdie, under the impulsive force of matched moulds first, drift 12 can deform according to the size of punching on the die 8, the time guaranteed the quality of fit of concavo-convex mould.And drift 12 is independently to be installed for shaping size at patrix 2 dishes, and promptly bolt 11 directly screws drift 12, can be on equipment when wearing and tearing the direct single drift 12 of replacing, omitted the step of last grinding machine cylindrical grinding; Simultaneously bearing 7 has been installed on patrix 4, when loading a die at first during matched moulds, has not been needed to rotate and wholely go up axle 1 or lower shaft 4, as long as rolling bearing 7 just can be aimed at drift 12 and punching 8 easily.
