Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 6, a novel connection structure of a cookware aluminum welding nail comprises a cookware body 1 and an aluminum welding nail 2, wherein a paint layer is coated on the cookware body 1, a positioning jack 3 is arranged on the cookware body 1, a positioning insertion block 4 is arranged at the front end of the aluminum welding nail 2, and the positioning insertion block 4 is inserted into the positioning jack 3;
still integrated into one piece has circular arc hem portion 5 on each lateral wall of aluminium weld nail 2, the outer end of circular arc hem portion 5 with pan body 1 butt is fixed together through laser welding.
Present product is in the production process, and the structural shape of aluminium welding nail 2 all is comparatively single tradition, lacks the prepositioning structure between aluminium welding nail 2 and the pan body 1, and the experience of splicing welder master completely removes to carry out the accuse to the welding position when handling, consequently has certain flaw certainly, for example the position precision of product is not high, and the uniformity is relatively poor etc.. According to the utility model, the pre-positioning function before welding can be realized through the matching of the positioning plug block 4 and the positioning jack 3, so that the welding position precision is higher.
The shape of the common aluminum welding nail 2 is square, cylindrical and the like, when the shape of the aluminum welding nail 2 is smooth, even if the aluminum welding nail is provided with the positioning insertion block 4 and the positioning insertion hole 3, the insertion direction is limited, but the aluminum welding nail still can rotate axially during welding, so that the welding effect is reduced. In order to solve the defects of the prior art, the embodiment is that each side wall of the positioning insertion block 4 is provided with an anti-rotation rib 6 outwards in a protruding manner, the positioning insertion hole 3 is provided with an anti-rotation groove 7 in which the anti-rotation rib 6 is inserted. The anti-rotation ribs 6 and the anti-rotation grooves 7 are matched to prevent axial rotation possibly existing during welding, and normal operation of laser welding is ensured.
Preferably, the cutting angle of the connection part of the arc edge part 5 and the pot body 1 is alpha, and alpha is less than 15 degrees. Adopt this preferred scheme, can make and almost reach plane welded degree between aluminium welding nail 2 and the pan body 1 to can make the welding degree of difficulty littleer, the welding seam after the welding is more level and more smooth, and the welding firmness is stronger.
The most common iron pan that all is of pan, with the help of the characteristic of iron pan, this embodiment is in the interior terminal surface of circular arc hem portion 5 coats and is coated with magnetic layer 8, magnetic layer 8 can with pan body 1 adsorb together to make the position precision of circular arc hem portion 5 higher, with the uniformity of further promotion product, be difficult to throw off after adsorbing simultaneously, so that follow-up welding operation carries out.
Preferably, the aluminum welding nail 2 is also coated with a paint layer which is the same as the cookware body 1. Of course, the aluminum welding nail 2 can also adopt a paint layer different from the cookware body 1 to match more product color combinations, which is not repeated herein.
In order to facilitate the connection and use of the panhandle, the rear end of the aluminum welding nail 2 is provided with a panhandle connecting groove. Referring to fig. 5, the connecting groove of the handle may be a threaded groove 9; referring to fig. 6, the diameter of the reducing groove 10 may be gradually reduced from inside to outside. The specific form of the connecting groove of the pan handle is various and is not limited in particular.
Laser welding is an efficient precision welding method using a laser beam with high energy density as a heat source. Laser welding can be achieved by using a continuous or pulsed laser beam, and the principle of laser welding can be divided into heat conduction type welding and laser deep fusion welding. The laser radiation heats the surface to be processed, the surface heat is diffused inwards through heat conduction, and the workpiece is melted by controlling laser parameters such as the width, the energy, the peak power, the repetition frequency and the like of laser pulses to form a specific molten pool. The utility model can firmly weld the aluminum welding nail coated with the paint layer and the pot body together by means of the characteristic of laser welding instead of the existing energy storage welding mode.
According to the novel connecting structure of the aluminum welding nail 2 for the cookware, provided by the utility model, during actual production operation, firstly, the cookware body 1 and the aluminum welding nail 2 are respectively coated with a paint layer, then the positioning insertion block 4 is inserted into the positioning insertion hole 3 in an aligning manner, the position of the anti-rotation rib 6 is matched with the position of the anti-rotation groove 7 in the insertion process, the arc attaching part 5 is attached to the outer wall of the cookware body 1 after the positioning insertion, the magnetic layer 8 can be adsorbed with the cookware body 1, a good pre-assembly effect is realized, and finally, the cookware body 1 and the aluminum welding nail 2 are fixed together by laser welding.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, changes and equivalent structural changes made to the above embodiments according to the technical spirit of the present invention still fall within the protection scope of the technical solution of the present invention.
