Abstract
The invention discloses a forming die for machining a chamfer of a metal plate type holed component upper hole without material removing. The forming die is provided with a punch die. The punch die comprises a die handle, an upper die plate, an upper die body, a lower die body and a lower die plate. The die handle is connected and fastened to the upper die plate through a thread. The upper die body is connected and fastened to the upper die plate through a bolt. The lower die body is connected and fastened to the lower die plate through a bolt. The forming die is characterized in that the lower die body is provided with a guiding positioning shaft and a forming face, the guiding positioning shaft is in a cylindrical shape so as to achieve a component positioning function, and meanwhile an upper die body and lower die body guiding function can be achieved. The forming face is in a frustum shape, the large-diameter end of the forming face is fixedly connected with the lower die body, the small-diameter end of the forming face is fixedly connected with the guiding positioning shaft, and therefore the chamfer of the component upper hole can be directly punched and formed through downward moving punching force of the upper die body. Due to the fact that the above structure is adopted, the forming die has the beneficial effects of being simple in structure, convenient to machine, high in machining precision, light, low in cost, short in machining period, high in work efficiency, attractive in appearance and the like.
Description
Technical field
The present invention relates to metal plastic forming field of mechanical technique, the mould of the chamfering in hole on specifically a kind of use non-removal materials processing panel beating class pored component.
Background technology
It is known that, panel beating class with the chamfering in hole on part generally all by remove material post-treatment molding, lathe turning or drilling machine drilling or milling machine milling or boring machine is generally adopted to process, lathe adds man-hour, need to by turning tool clamping on the scroll chuck of lathe, again workpiece is passed through bolt and be connected laggard row turnery processing with turning tool, could unload by workpiece after bolt being unloaded with spanner again after machining, and the work pieces process for complex contour gets up more difficult, the chamfer machining in hole especially in irregular shape is got up more extremely difficult, not only process loaded down with trivial details, handling inconvenience, inefficiency, processing cost is high and Workpiece Machining Accuracy is low.
Summary of the invention
Present invention aim to address above-mentioned the deficiencies in the prior art, it is provided that a kind of simple in construction, easy to process, machining accuracy is high, lightweight, cost is low, the process-cycle is short, work efficiency is high, good looking appearance mould of the chamfering in hole on non-removal materials processing panel beating class pored component.
The technical solution adopted for the present invention to solve the technical problems is:
The mould of the chamfering in hole on a kind of use non-removal materials processing panel beating class pored component, it is provided with punch die, it includes die shank, cope match-plate pattern, upper mould, counterdie and lower bolster composition, die shank is threaded connection and is fastened on cope match-plate pattern, upper mould is bolted and is fastened on cope match-plate pattern, counterdie is bolted and is fastened on lower bolster, it is characterized in that described counterdie is provided with guide-localization axle and forming surface, described guide-localization axle is cylindrical, to reach the effect of locating element, the effect of upper and lower mould guiding can be played again simultaneously, described forming surface is taper type, described forming surface bigger diameter end is fixing with counterdie to be connected, miner diameter end is fixing with guide-localization axle to be connected, the stamping press being beneficial to be moved down by upper mould is by the direct punch forming of the chamfering in hole on part.
The present invention can be provided with on counterdie and unload charge bar, described in unload charge bar be elastomeric element, described counterdie is provided with and unloads hole, charge bar location, described in unload charge bar and be placed on the unloading in hole, charge bar location of counterdie, be beneficial to the part after by punching press and directly upspring, reach easy to operate effect.
Forming surface of the present invention is cone, and the vertebral body of described forming surface is within C5, and the stamping press being beneficial to be moved down by upper mould is by the direct punch forming of the chamfering in hole on part.
Forming surface outer wall of the present invention can be also kidney-shaped vertebral body, within the circular arc of the kidney-shaped vertebral body of described forming surface may be provided at R5, to reach stamping press that punching press moved down by upper mould by the direct punch forming of the rounding in hole on part.
Due to the fact that employing said structure, there is simple in construction, the advantage such as easy to process, machining accuracy is high, lightweight, cost is low, the process-cycle is short, work efficiency is high, good looking appearance.
