Abstract

The invention belongs to the lock field and provides a production method of aluminium alloy lock panel connecting column. The production method includes the following steps: (1) aluminium alloy round bar or rectangular bar is punched or subject to lathe processing to be in the required size; (2) aluminium alloy panel is subject to blanking by a mould, is punched into the required size and then is stretched and moulded into the required shape; (3) the two parts are completed and then forging and stamping are carried out, the aluminium alloy panel is placed into a tunnel heating furnace, is subject to preheating and heat perseveration and then is taken out at 490-530 DEG C, the aluminium alloy panel is placed into the mould and pressure is adjusted according to requirement, and meanwhile the aluminium alloy connecting column is placed into the mould, and the lock panel and the connecting column are subject to one-step forging and stamping. The lock panel of the invention is subject to aluminium alloy forging, the produced aluminium alloy lock panel product is subject to further post treatment, the produced lock panel connecting column is stable in connection, high in rigidity, difficult to fade and anti-static, and post treatment is easy to be carried out on the lock panel.

Description

The production method of aluminium alloy lock panel connecting column
Technical field
The present invention relates to the lock field, relate in particular to a kind of production method of lock panel connecting column.
Background technology
Lock panel on the market adopts the kirsite manufacturing mostly at present, be to adopt zinc alloy diecasting, plating or injector surface etc., lock panel with this technology manufacturing, exist overlay coating easily to come off, color is single, use after about 1 year, special ugly, higher or the like the shortcoming and defect of antistatic, cost not just seems.
Make panel with aluminium alloy, also the someone developed in the past, but all failed, a kind of do not have intensity with aluminium die casting, product, the surface can not anode, can only electroplate or the oil spout effect does not have the good of kirsite, and a period of time does not just have market, two kinds have the people also the lock handle to be made of the forging mode, but can not do good intensity and surface of good effect.It more than is a great problem of lock industry.The no one can solve.
Present lock panel all is to adopt the mode of joint pin to be connected with base plate.
Summary of the invention
The technical problem to be solved in the present invention is the above-mentioned shortcoming that overcomes prior art, provides a kind of novel employing aluminium alloy to make the production method of lock panel connecting column.
The production method of aluminium alloy lock panel connecting column of the present invention, its scheme may further comprise the steps:
(1) prepares the aluminium alloy joint pin: become required size by punching press or machined into aluminium alloy pole or square bar;
(2) prepare aluminium alloy lock panel: aluminium alloy panel mould blanking, strike out required size, drawing and forming is to required shape then;
(3) forging and pressing: above two parts forge and press after finishing again, aluminium alloy panel is put into the tunnel heating furnace, by preheating, heating, being incubated tapping temperature is 490~530 ℃, put into mould and mix up the pressure size on demand, simultaneously the aluminium alloy joint pin is put into mould, with lock panel and forging forming of joint pin.
In order to make the present invention reach better effect, the tapping temperature of step (3) can be preferred 500~520 ℃.
Better for the surface property that makes lock panel, can carry out following processing to lock panel: again lock panel is heat-treated to HB37 after forging and pressing, the product after the heat treatment is removed rim charge earlier, then according to handle, turn-knob the position punching press is set, hole, tapping.
Also can further comprise the steps: the section of the side of manual polishing lock panel, vibrate the surface 2~4 hours of water mill polishing lock panel then.
Also can further comprise the steps: to do and throw: walnut grain and polishing agent with 20~40, slightly threw 5~7 hours, threw 3~5 hours with 60~100 walnut grains are smart again.
Also can further comprise the steps: the smart anode processing of throwing afterwards again.
Described aluminium alloy joint pin is preferably AL6061, AL6063.
When selecting Al6061 for use, before step (2) is heat-treated, also the aluminium alloy joint pin is carried out T4, T6 and handle, AL6061 carries out T5 to be handled.
Joint pin is used to connect the front and back panel (rear board is base plate again) of lock, be located at the back side of the front panel of lock, traditional method is one-body molded or be welded to connect post and make in the mode of back side of panel by the mode of cast molding and panel, and shortcoming is to be difficult for surface treatment, and is not attractive in appearance.The present invention adopts riveted way to make, and adopts aluminium alloy to make, and the intensity height is easy to surface treatment, attractive in appearance.
The aluminum alloy forged mode of lock panel, former no one did, because two of this products are high protruding, area is big, the wall book is very big, impossible in theory with forging mode difficulty.The application passes through process modification, a panel is disposable to process to adopt the riveted joint mode to combine with forging and pressing, the kirsite panel drawback that adopted aluminum alloy forged process improving, the colour stable of product, and color is various, can need collocation arbitrarily with the client, and antistatic, product strength is better than kirsite, and the produce market future is huge.
The aluminium alloy lock panel products of being produced is carried out further post processing, solved the defective that aluminium alloy is difficult to make high-quality surface; Improved the hardness of aluminium alloy panel and joint pin by heat treatment; Improve glossing (prior art all adopts manual polishing, throws technology with mechanical dry now), also adopt anode processing technique then, make aluminum alloy surface reach preferable effect, solved the problem that kirsite panel of the prior art fades easily.
