Abstract
The utility model relates to an improved structure of punching apparatus, comprising a pressboard, a tool fixed seat and a base, wherein the tool fixed seat is structured by a plurality of cylindrical cutting tools, a recovery spring and a file slot and is fixedly arranged on a fixed sheet holder provided with a plurality of guide channels through a fastening lock; the fixed sheet holder is fixed on a base platform by riveting; pressing plates are pivotally connected with each other through pivot ears which are arranged on both sides of the pressing plates and protrude towards both sides of the base platform; a reinforced construction with reinforced edges is formed by circumference parts of various hollow grooves of the base platform being bended towards the end face; the height of the reinforced edges are just close to the base material thickness of the platform which is then made to have better supporting intensity, thereby the base materials of the base platform can still adopt thinner thickness and pressure-proof and deformation resistant structural strength, consequently the phenomena of bending and depression can be avoided; and a connecting part between the pivot ears on both sides of the base platform and the platform can be lengthened to be close to the back end of the platform, thereby the supporting bending resistance on both sides of the platform can be improved.
Description
Technical field
The utility model is relevant with the adjustable porous perforating machine that bound document is used, and specifically, is that base has the puncher that improves structure.
Background technology
Existing adjustable porous perforating machine has a pressboard, a cutter holder and a base, the cutter holder has cutter, returning spring, a file groups of slots that is cylindricality to establish and form, and fasten body locking by one and be positioned on the fixing frame plate of some tool guide grooves, again with the fixing frame plate rivet clasp on the formed platform of base, the platform centre of base is provided with the dead slot that some relative cutters stretch out, but upwards protrude out the pivot ear that voltage supply making sheet both sides are pivoted respectively in both sides, but its sheathed paper supply in below is opened the receiver that chip stores.Make each cutter of being suppressed on the cutter holder behind the pressboard pressurized implement the punching operation to file paper, in operation process, press power is transmitted to the platform dead slot of file paper to base by cutter on the one hand, on the other hand through cutter be transmitted to cutter holder and fixing frame plate etc. mutually the overlap joint member of conflicting then indirectly-acting in platform, platform is the formation plate equipment structure, can cause the bent recess phenomenon after frequent stressed use a period of time, cause the drilling operation irregularity, influence product quality.For solving this problem, there is the people directly to increase the metal base thickness of base, so should increase material cost and cause the heavy inconvenience of puncher again.
Summary of the invention
Main purpose of the present utility model is to provide a kind of improvement structure of puncher, each dead slot peripheral region at base platform becomes the reinforcement edge-reinforcing structure close with land thickness to the bottom surface towards bending, uses and improves platform support bending strength and need not increase sheet metal thickness;
Another purpose of the present utility model is to provide a kind of improvement structure of puncher, and with the extension that extends backward of base platform both sides pivot ear and platform body junction, connecting width by this increases, and improves the bending resistance support strength of platform both sides.
The technical solution of the utility model is: a kind of improvement structure of puncher, comprise a pressboard, cutter holder and base are formed, wherein the cutter holder is by the cutter of some tool cylindricalitys, returning spring, the file slot assembles and forms, and be positioned on the fixing frame plate of some tool guide grooves by fastening body locking, the fixing frame plate rivet clasp is in base platform, the pivot ear that pressboard mat both sides and base platform both sides protrude out is pivoted mutually, it is characterized in that, each dead slot peripheral region of base platform becomes one to strengthen the reinforced structure of edge to the bottom surface towards bending, and strengthen the height of edge just can be close with the base material thickness of platform.
As further improvement, the pivot ear of base platform both sides and platform body connecting portion extend backward and extend convergence platform rear end.
Above-mentioned improvement project advantage is: the some dead slot peripheries on the base platform dash curved the extension to the bottom surface and constitute the effect of strengthening rim structures, the height of rim is close with the thickness of platform, make base platform have preferable support strength, so, the base material of base platform still can adopt thin thickness and have preferable withstand voltage and resistance to deformation structural strength, thereby avoids the bent recess phenomenon.

The specific embodiment
Consult each accompanying drawing, puncher shown in Figure 1 mainly is made up of a pressboard 10, cutter holder 20 and a base 30; Wherein, cutter holder 20 is established for 23 groups by cutter 21, returning spring 22, the file slot of some tool cylindricalitys and is formed, and be positioned on the L shaped fixing frame plate 25 of some tool guide grooves 251 by fastening body 24 locking, but cutter holder 20 integral body mat fixing frame plates 25 rivet clasps are in the appropriate location of base 30 platforms 31; Platform 31 centre of base 30 are provided with the dead slot 32 that some relative cutters 21 stretch out, but and upwards protrude out the pivot ear 33 that a voltage supply making sheet 10 both sides are pivoted respectively in both sides, base is installed with one for 30 times can fall into the receiver 34 (Fig. 2, shown in Figure 3 is consulted in cooperation) that stores for the cutting chip, after making file paper 40 insert the slot 23 of cutter holder 20, mat is pushed pressboard 10 forces each cutter 21 to finish drilling operation towards cutting paper, and the paper bits fall in the receiver 34 via dead slot 32.
See shown in Figure 3, because file paper 40 places the slot 23 of cutter holder 20 bottoms, when pressboard 10 compresses each cutter 21 top, each cutter 21 direct die cut paper, if file paper 40 numbers are more, then pressboard 10 need apply bigger pressing force, and acts on simultaneously through cutter 21 on the dead slot 32 of file paper 40 and platform 31, stressed on the other hand paper passes to cutter holder 20, fixing frame plate 25 again, and also indirectly-acting is on the platform 31 of base 30; Therefore, locate stressed maximum around the dead slot 32 of platform 31 with respect to cutter 21 cutting mouths 211, hereat, the utility model is by the reinforcement edge of establishing in the dead slot 32 periphery upper punches of base 30 platforms 31 321, effectively increase its support strength after stressed, can prevent to produce collapse-deformation behind platform 31 pressurizeds.
Consult Fig. 4, base 30 platforms 31 need directly or indirectly bear compacting stress, its span (being the width of platform 31) is big more, then its bending strength is poor more, edge this, the utility model is strengthened the edge 321 except dead slot 311 places in platform 31 are provided with, and also the pivot ear 33 of platform 31 both sides extend backward with platform body connecting portion 331 and extends convergence platform rear end, with the support flexing resistance of increase platform 31 both sides.
