Description
Technical field
The present invention relates to a kind of radiator centre and dry complementary equipment required when welding, particularly relate to the one adopted when a kind of 16 width radiator centres dry weldering and restrain tool.
Background technology
The contained tool drying weldering for radiator centre assembles and be used in baking weldering process clamping radiator centre, make it to be ensured by tool relative to the positional precision of fuse kludge, thus ensure that the radiator centre drying postwelding is not by the impact of workman's technical merit, makes the machining accuracy of product reach unanimity.This contained tool being used for radiator centre is mainly used in assembling in radiator centre manufacture process, dries welder's sequence.For the design of the contained tool of radiator centre for the purpose of ensureing that involved procedure requires, ensure emphatically assembling product size and dry weldering quality; Package size mainly refers to the spacing dimension of radiator centre two backplate, and all the other such as main leaf spacing dimensions are then ensured by kludge; Dry weldering quality and mainly refer to that, except baking soldering equipment relative parameters setting, restrain tool dries weldering quality impact on product, it mainly ensures with product quality and appearance and size.
In prior art, although the requirement on machining accuracy of product can be ensured at the assembling procedure of product, but in follow-up baking welder sequence, because contained tool is not usually adjusted to the right place (keeping certain spacing with radiating tube) by workman, under high temperature, (625 DEG C) dry weldering and cause contained tool to contact with radiating tube to cause the perforation of radiating tube or heat-radiation belt corrode to produce bad scrapping.
Summary of the invention
The shortcoming of prior art in view of the above, the object of the present invention is to provide a kind of contained tool drying weldering for radiator, prevent and produce the bad phenomenon such as adhesion ablation, perforation because of contained tool and radiating tube spacing deficiency in baking weldering process, improve and dry weldering quality.
For achieving the above object and other relevant objects, the invention provides a kind of contained tool drying weldering for radiator centre, comprise body, be arranged at the left clamping section of body left end and be arranged at the right clamping section of body right-hand member, described body comprises the first cross bar and second cross bar isometric with the first cross bar, the left end of the left end of the first cross bar and the second cross bar is flushed connection by left clamping section, the right-hand member of the right-hand member of the first cross bar and the second cross bar is flushed connection by right clamping section, first cross bar and the second cross bar are rectangular structure, the two ends of the first cross bar and the second cross bar two ends are provided with trapezoidal groove and each trapezoidal groove is 17.3mm to the distance of each end, the width of trapezoidal groove is 5.2mm, 66 circular grooves are evenly provided with and circular groove is arranged at the centre of the trapezoidal groove at two ends at the middle part of the first cross bar and the second cross bar, spacing between two adjacent circular grooves is 8.2mm, the diameter of circular groove is 3.5mm.Because radiator centre is when keeping flat, the surface of radiating tube usually outstanding radiator centre, therefore when with restraining the tool clamping radiator core period of the day from 11 p.m. to 1 a.m, the first cross bar and the second cross bar can with radiating tube adhesion, thus radiating tube burnt, bore a hole; When in order to do not allow the first cross bar and the second cross bar and the adhesion of radiating tube portion time, contained tool can be made again inadequate to the clamping force of radiator centre, the relative position of radiating tube and heat-radiation belt is offset in baking weldering process.Each trapezoidal groove is 17.3mm to the distance of each end, and this distance matches with the distance of the radiating tube at the edge of 16 width radiator centres to the edge of backplate; The width of trapezoidal groove is 5.2mm, the width of the radiating tube at the edge of this width and 16 width radiator centres matches, after contained tool so just can be made to clamp radiator centre, just the radiating tube at the edge of 16 width radiator centres can be contained in trapezoidal groove.The number of circular groove is 66, and the number of the radiating tube of the centre of this number and 16 width radiator centres matches; Spacing between two adjacent circular grooves is 8.2mm, this spacing be and 16 width radiator centres centre radiating tube between distance match; The width of circular groove is 3.5mm, the width of the radiating tube of the centre of this width and 16 width radiator centres matches, after contained tool so just can be made to clamp radiator centre, just the radiating tube of the centre of 16 width radiator centres can be contained in circular groove.Prevent and produce the bad phenomenon such as adhesion ablation, perforation because of contained tool and radiating tube spacing deficiency in baking weldering process, improve and dry weldering quality.
