Abstract

The utility model relates to a novel punching module suitable for rapidly punching shape holes in the middle of an aluminium alloy hollow section material, which comprises an upper and a lower modules, wherein the upper module is clamped on a sliding punching head of a punching machine, the lower module corresponding to the upper module is fixedly arranged on the front end of a lower module seat plate of a purpose-made lower die carrier fixed on a working table of the punching machine, and a gap slightly larger than the wall thickness of the aluminium alloy section material is arranged between the lower plane of the front-section part of the lower module seat plate and the upper plane of the lower die carrier. The largest cross section of the lower module corresponds to the shape of an inner cavity of the section material and is in a loose fit with the inner cavity, the blanks of the section material are sheathed on the limited position of the front section of the lower module seat plate provided with the lower module and then the section material can be punched with required shape holes.

Description

Aluminium alloy hollow section material punching module

The utility model relates to a kind of punching die, particularly a kind of aluminium alloy hollow section perforating die that is suitable for the shape hole on the quick punch process aluminium alloy hollow section middle part.

At present, to hollow section, particularly for the shape hole on the used aluminium alloy hollow section middle part of assembling aluminum alloy doors and windows, generally all continue to use: operation means such as " line---shaping of deburring angle is manually filed in boring---milling reaming---" shape.This explained hereafter cycle length, worker expend with high, but the output value is extremely low; And, not only can't guarantee the hole shape quality with common punch die punch process, and easily make whole piece section bar distortion hurt, so that scrap.

The utility model just can particularly impact the punching die of processing aluminium alloy hollow section middle part upper shape hole for the public provides a kind of quick punch process hollow section that is specifically designed to.

This novel perforating die also is partly to be made of upper module and lower module two on the whole, the upper module clamping is on the slip drift of punch press, lower module then is with corresponding with upper module position, device is on the front end position of the lower module seat board on the special following mould bases, lower module seat board leading portion partly lower plane and the last plane of following mould bases between to be slightly larger than the clearance distance of aluminium alloy hollow section wall thickness, and be packed in down with its rear end on the position, rear end of mould bases, following mould bases then is packed on the punch press, on lower module and the lower module seat board, lower plane and down mould bases last plane all with the last plane parallel of punch press workbench, the shape and size of the maximum cross section of lower module are to prepare mutually with loose fit with the geomery of the cross section of aluminium alloy hollow section inner chamber, the cross sectional dimensions of lower module seat board is slightly smaller than the size of the maximum cross section of lower module, so that the leading portion of lower module and lower module seat board partly all can be inserted among the inner chamber of aluminium alloy extrusions deeply.

When using the utility model, only need aluminium alloy hollow section cover is being installed on the qualification position at lower module seat board leading portion position of lower module, start punch press, can quick punching out go out required shape hole, and the shape hole that processes like this needn't be again through manual amendment; To difform shape hole, gone up corresponding upper and lower module as long as change the outfit.The structure of this novel perforating die is very simple, and very practical, the shape hole processing technology of the aluminium alloy hollow section middle part of routine can be simplified greatly, saves man-hour, manpower, workpiece to be difficult for impaired distortion, can reduce production costs effectively.

Below, we are described in detail embodiment of the present utility model by accompanying drawing:

Fig. 1 is the utility model working condition configuration diagram;

Fig. 2 is the utility model general structure diagrammatic sketch;

Fig. 3 is the upward view of lower module.

Being used to assemble the aluminium alloy hollow section of aluminum alloy doors and windows, mainly is that cross section is tetragonal section bar, and its wall thickness is generally all thinner, and shearing force required during to its punching out shape hole is very little, uses so the utility model can be installed on the small-sized punch press below 25 tons.The version of its upper module (2) the upper module version with commonly used common perforating die basically is identical, is mostly to make punch, and resembles and be installed on the slip drift of punch press (1) the common upper module; Its lower module (3) is to make corresponding die naturally.The cross section of lower module (3) is to be and the corresponding quadrangle of aluminium alloy hollow section inner chamber cross section, and the size of its maximum cross section is to prepare with loose fit with aluminium alloy hollow section inner cavity size; Lower module (3) is with on the fastening fitting plane that is installed in lower module seat board (4) front end position of the fitting plane of its rear end and positioning spigot, and with the shop bolt location, the design in forming cavity in the lower module (3) and filings-containing cavity, chip removal chamber can be similar with common perforating die.The cross section of lower module seat board (4) is the quadrangle that lateral dimensions is smaller than lower module (3) maximum cross section lateral dimensions.The rear end of lower module seat board (4) and following mould bases (6) the rear end section of fitting, be that a wall thickness that is higher than an aluminium alloy hollow section on leading portion part plane adds 0.05～1 millimeter protruding platform more in addition, instantly the rear end of module seat board (4) is packed in down after mould bases (6) position, rear end, just form a treaty naturally greater than about 0.05～1 millimeter slit of aluminium alloy hollow section wall thickness between the lower plane of its leading portion part and lower module (3) and the last plane of following mould bases (6), when aluminium alloy hollow section (7) overlapped on lower module seat board (4) the leading portion position that is installing to lower module (3), the lower plane of aluminium alloy hollow section (7) was 0.05～1 millimeter with the last interplanar distance of following mould bases (6) is also just maximum.Simultaneously, following mould bases (6) is to be packed on the workbench of punch press (1), the upper and lower plane of lower module (3) and lower module seat board (4), and the last plane of mould bases (6) parallels with the work top of punch press (1) down, so encapsulation is parallel to the work top of punch press (1) too at the last lower plane of the aluminium alloy hollow section (7) of this novel perforating die, when upper module (2) carried out punching to it, aluminium alloy hollow section (7) scratched with regard to slippage not occurring or is gone out the shape hole that distortion is lost shape by punching out.To the most simple and practical limit method of aluminium alloy hollow section (7), clamping is fixed a shape and is resembled arc position limiting clamp (5) the micrometer on lower module seat board (4) upper limit allocation exactly.Like this, the blank to same size requires after the one-time positioning, just can carry out batch machining.
