Description

A kind of punching die

Technical field

The utility model relates to a kind of punching die, is meant a kind of punching die that is used in thin-walled body upper punch equidistant holes especially.

Background technology

At present, finish in the mode of execute-in-place in that thin-walled body upper punch equidistant holes is many, promptly carry out with the mode of bench drill perforate, waste time and energy, efficient is low with back, artificial measuring and calculating location, and the high scrappage that very easily causes the light-wall pipe body deformability and cause thus, and the scrappage of super hole cutter drill bit is also high.In order to raise the efficiency, to reduce cost, many designs that substitute on-the-spot boring with punching have been proposed.China's ZL93215219.8 patent " punching die of window aluminium extruded type " discloses a kind of punching die of window aluminium extruded type, establish locating hole by counterdie, keep supplying mould, the on-off action that bed die becomes to coincide with post, and each can become to reset with flexible member, counterdie has digital-to-analogue seat and die cavity, can keep supplying the jumper bar of mould and tringle and be deep into and charge and attack hole or scarce hole; Die cavity then protrudes for the module of bed die, inserts for the type of squeezing with the groove of module, and module is descended at die cavity, becomes punching, cuts the crowded type of cutting.This design complex structure, the mode that adopts a plurality of moulds to operate simultaneously only suits to operate on punch press, is not suitable at the construction field (site) timely operation and manual operations, particularly in process, can't solve definite problem of position, continuous hole, efficient and accuracy are had a greatly reduced quality.

The utility model content

The problem that the utility model need solve provides a kind of punching die that can use in the erecting bed, and this mould can be supporting with punch press, also can on-the-spot manual operations or with small desk machinery, particularly solved porous and located this difficult problem continuously.

Designed a kind of punching die according to the above-mentioned problem that needs to solve, comprise lower bolster, the lower bolster setting also is fixed on the base plate, be provided with the master mold supporting at the lower bolster middle part with drift, also be installed with one in a side of lower bolster and be in gag lever post in the same plane with lower bolster, gag lever post is shelved on the scale plate that also is installed in lower bolster the same side; On the scale plate of gag lever post both sides, offer through slot, locating rack is connected with the scale plate and locatees and fixing by the bolt that passes two through slots respectively; The locating rack that is the Jiong type is connected across on the gag lever post, and the crossbeam of locating rack is provided with the registration roller wheel assembly, and this registration roller wheel assembly cooperates with chock fixed bar on being shelved on gag lever post, and the working end of chock fixed bar is provided with the master mold chock with the master mold coupling.

During concrete enforcement, needing have scale in the side delineation of scale plate, and this scale cooperates the location with mark on the locating rack.Described registration roller wheel assembly is made up of location running roller, roller frame, back-moving spring and locating rack, location running roller wherein and Jiong type registration roller wheel carrier are coupling, this roller frame is installed on the crossbeam of locating rack by bolt, be enclosed within back-moving spring on the bolt and make the registration roller wheel be pressed on the shaft of chock fixed bar and can roll on shaft, the free end of chock fixed bar can be fixedlyed connected with the end of gag lever post by bolt.The chock fixed bar then is connected with the master mold chock by screw rod, and the master mold chock is with the master mold coupling and be provided with the through hole consistent, that supply drift to pass with master mold.The female die seat hole that is arranged in the lower bolster middle part is placed and be fixed on to master mold, between master mold and female die seat hole for screw togather engage or plug together or location that other suits with fixedly connected.On lower bolster, also be provided with adjustable guide pad before and after the position, guide pad prolongs to parallel with gag lever post, with guide pad every the female die seat hole relative be nip rolls, nip rolls and Jiong forming roll frame are coupling, the roller frame is rack-mount by bolt, support is fixed on the lower bolster, is enclosed within compression back-moving spring on the bolt and makes nip rolls be pressed on the master mold chock and can roll on chock.

The utility model is small-sized frock clamp and mould, simple in structure, parts are few, easy to manufacture, can increase substantially the efficient of on thin-wall pipes, processing different size, shape equidistant holes in the cold punching mode, accurate positioning, crudy are good, scrappage is extremely low, both can also can mate, be beneficial to on-the-spot the use with large-scale die cutting device is supporting with mini-plant.Unit is specially adapted to process the small-sized workshop of anti-theft net class, and " parallel connection " formula multimachine is applicable to main equipment.
