Abstract
The utility model relates to a punching device for an adjusting shim. The utility model mainly solves the problems in the prior art of difficulty processing and low working efficiency in the manual processing way, and high cost in the laser processing way. The punching device for the adjusting shim comprises a base; a plurality of punched holes are formed on the base; punches are arranged in the punched holes; and a crack is formed on the side of the base, and intersects with the punched holes. The punching device for the adjusting shim has the advantages of simple structure and low manufacturing cost, is simple to operate and improves the working efficiency.
Description
Technical field
The utility model relates to a kind of hole punched device, relate in particular to a kind of simple in structure, the adjustment pad hole punched device of low cost of manufacture.
Background technology
The cold punching die requirement on machining accuracy is than higher, some large-scale vehicle exterior cladding element moulds particularly, and domestic level of processing is difficult to guarantee its precision.After the NC digital control processing finishes, often need the accurate processing of pincers worker to debug the operating accuracy that satisfies mould repeatedly, reach the product design requirement.The general industry of mould all adopts silicon steel sheet, and this material material is harder, and fatigue resistance is stronger, uses the coil feed line blanking to make.The purchase size of product all is to be provided by manufacturing firm, and the size that producer provides needs post-production to use, pincers worker generally uses scissors to process, because material is too hard, scissor cut processing is very difficult, particularly endoporus uses scissors to be difficult to reach the circularity requirement, has a strong impact on operating efficiency.More external large mold manufacturing firms utilize the laser cutting machined, though natural precision is guaranteed, have increased processing cost, have caused waste.Therefore need a kind of cost of design equipment low, easy to process.China utility model 200720032812.X discloses a kind of pad hole punched device, it comprises pedestal, in the middle of pedestal, be provided with groove, have through hole and lower through-hole in the last lower base of groove, be connected with depression bar by connecting rod on the pedestal, be provided with jumper bar between depression bar and the pedestal, overcoat back-moving spring on the jumper bar, depression bar is connected with the jumper bar upper end, jumper bar passes the fairlead in the through hole, and the lower end of jumper bar is equipped with upper blade, and the upper surface of groove is equipped with demoulding baffle plate, the lower surface of groove is equipped with the former seat, is equipped with down towards sword in the middle of the former seat.The light sheet material that this device will be processed is placed on the demoulding baffle plate, presses down-pressed pole, promotes jumper bar by linkage and moves downward, and jumper bar drives upper blade and carries out punching.But the demoulding baffle plate of this device is too little, when processed thin plate is big, need with hand steered firmly, processed thin plate may produce inclination, influences the degree of accuracy of punching press.
Summary of the invention
The utility model has mainly solved the manual processing of available technology adopting, processing difficulties, and inefficiency, and use the high problem of Laser Processing cost, provide a kind of simple in structure, the adjustment pad hole punched device of low cost of manufacture.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of adjustment pad hole punched device, comprise base, on base, have several punchings, be provided with drift in the described punching, have one the slit on the side of base, described slit and punching are intersected.Punching runs through base, and the slit of offering on the base is used to place the plate of needs processing, during punching, only needs drift is put into punching, with hammer the drift upper end is knocked, and can finish the punching to plate, and is simple to operation.The utility model is simple in structure, and is easy to make, reduced production cost.
A kind of preferred version as such scheme, described base is square platy structure, and open on the leading flank of base in described slit, and this slit is extanded rearward near the trailing flank position by leading flank, and on the left and right side, forming opening, the plane and the described punching at place, described slit are perpendicular.This slit is opened in centre position, base side, makes base form the structure that a cross section is a U-shaped, and slit and punching are perpendicular, makes that the hole of going out is more accurate.
As a kind of preferred version of such scheme, the thickness in described slit is 0.5mm ~ 0.8mm.Make and to insert processed plate.
As a kind of preferred version of such scheme, the upper end of described drift is provided with a circle convex edge.Drift beats by hammer and carries out punching, is provided with the convex edge in the drift upper end, has increased the area of drift upper end, and it is more accurate to make that hammer beats, handled easily.
A kind of preferred version as such scheme is with cushion collar on described drift, described cushion collar upper end withstands on lower end, described convex edge, and the cushion collar lower end withstands on the described base.Cushion collar plays cushioning effect to drift, in addition, by the cushion pad resilience drift is resetted when drift is pressed into bottom dead centre.
The utility model has the advantages that simple in structure, low cost of manufacture, simultaneously simple to operate, improved operating efficiency.
Description of drawings
Fig. 1 is a kind of structural representation of facing of the present utility model;
Fig. 2 is a kind of plan structure schematic diagram of the present utility model;
Fig. 3 is a kind of side-looking structural representation of the present utility model.
The specific embodiment:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described.
Embodiment:
A kind of adjustment pad of present embodiment hole punched device, as shown in Figure 1, comprise a base 1, on base, have two punchings 2 that run through base, on the leading flank of base, have slit 4, as shown in Figures 2 and 3, extend towards the base trailing flank in this slit, terminates in the position near trailing flank, and form opening on the left and right side, punching is passed in this slit, and the plane at place, slit and punching are perpendicular.Be provided with drift 3 in punching, this drift upper end is provided with convex edge 6, is with cushion collar 5 on drift, and the cushion collar upper end fixes on the lower end, convex edge, and the cushion collar lower end withstands on the base.Base adopts the 45# steel plate of 120*110*20mm to make in the present embodiment, the diameter that is opened in two punchings on the base is respectively 12mm and 14mm, the thickness in slit is 0.5mm, the rear end in this slit is that dotted line is 10mm to the distance between the upper end among Fig. 2 to the distance of the trailing flank of base, and cushion collar adopts polyurethane to make.
Device is put into the slit with processed thin plate earlier in use, and the drift that will be with cushion pad is then put into punching, knock the drift upper end with hammer, drift moves downward finishes punching, and when drift was pressed into bottom dead centre, cushion collar was returned to the origin-location by resilience with drift.
Specific embodiment described herein only is that the present invention's spirit is illustrated.The technical staff of the technical field of the invention can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although this paper has used terms such as drift, base, punching, cushion collar, convex edge morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present invention more easily; They are construed to any additional restriction all is contrary with spirit of the present invention.
