Abstract
The utility model relates to a metal tube wall convex aperture drawing device comprising a hydraulic control cabinet. A start button is arranged on the front surface of the hydraulic control cabinet; a frame is arranged on the top surface of the hydraulic control cabinet; a double-rail hydraulic elevation device is arranged on the frame; a compression protective plate is arranged between the double rails of the double-rail hydraulic elevation device; a drawing mold is arranged below the compression protective plate; a workpiece protection mold sleeve is arranged below the drawing mold; a boss protective sleeve connection rod is arranged on the bottom surface of the workpiece protection mold sleeve; hydraulic guide rails are respectively arranged on the double rails of the double-rail hydraulic elevation device; and a mold loading block is arranged between the two hydraulic guide rails. According to the device provided by the utility model, downward compression is carried out through a hydraulic pressure generating device; the drawing mold is linked and moved; and the convex aperture with a boss is drawn outwards from the inner wall of the metal tube. The device is more convenient and accurate. With the device, size and positioning deviations are prevented, yield is high, working efficiency is improved, and raw material loss is greatly reduced. The device is energy-saving and environment-friendly.
Description
Technical field
The utility model relates to a kind of metal tube tube wall evagination aperture draw-off gear.
Background technology
In automobile (air-conditioning) accessory industry two device joints, connect chew with car air-conditioner silencer Chang Yuxu outwardly and chew shape with connecing of boss through the metal tube inner tubal wall.Prior art generally adopts first foundry goods, then cut with scissors (drawing) empty inner chamber mode, or adopt prefabricated boss parts then synthetic with metal tube perforate welding, the former waste of raw materials serious (waste rate 〉=90%), the latter process is cumbersome, and quality can't guarantee (weld strength variance, leakage etc.) phenomenon; Serious waste of resources, quality is low, at the bottom of the yield rate, the operating efficiency extreme difference, speed is slow, and the activity duration is long, and efficiency is low, and manufacturing cost is large.
The utility model content
The purpose of this utility model provides a kind of metal tube tube wall evagination aperture draw-off gear, overcomes the deficiency of the above-mentioned aspect of prior art existence.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of metal tube tube wall evagination aperture draw-off gear; comprise the hydraulic control cabinet; the front of described hydraulic control cabinet is provided with start button; the end face of hydraulic control cabinet is provided with frame; frame is provided with the double track hydraulic lift; be provided with between the double track of double track hydraulic lift and press down backplate; the below that presses down backplate is provided with drawing mould; the below of drawing mould is provided with workpiece protection die sleeve; the bottom surface of workpiece protection die sleeve is provided with boss sheath connecting rod; be respectively equipped with the hydraulic pressure guide rail on the double track of described double track hydraulic lift, be provided with patrix between two hydraulic pressure guide rails and load piece.
Further, a side of described double track hydraulic lift is provided with up stroke switch and downward storke switch.
Further, described hydraulic control cabinet is connected with semi-automatic floor push by circuit.
The beneficial effects of the utility model are: press by (OK) under the pressure hydraulic generator, the interlock drawing mould, be pulled outwardly from inner wall of metal tube and extract boss, overhanging aperture (connect and chew), convenient, accurate, can not produce size, deviations situation, yield rate is high, increase operating efficiency, simultaneously significantly reduce the raw material loss, energy-conserving and environment-protective, enterprise economic benefit and social benefit.
