Abstract
The invention discloses an angle steel clamp welding bench and an angle steel clamp welding process. The welding bench composed of two steel plates and with an inner side included angle slightly larger than 90 degrees is arranged and used for welding angle steel clamps. During welding, the angle steel clamps only need to be placed on the welding bench, two side edges of each angle steel clamp are enabled to fit with two side edges of the welding bench, and at the moment, reinforcing ribs are welded on the inner sides of the angle steel clamps. Therefore, when the angle steel clamps are taken down from the welding bench after welding is finished, welding seams are shrunk, an included angle between two side edges of each angle steel clamp is decreased, part of angle widened on the welding bench can be offset, the included angle between two side edges of each angle steel clamp can return to about 90 degrees, errors of the included angles caused in a welding process are reduced, production qualified rate is improved, and requirements on transformer mounting are met.
Description
Technical field
the present invention relates to a kind of welding bench and welding procedure of angle steel folder.
?
Background technology
often needing to arrange the used for rail vehicle transformer on high speed railway car provides electric energy for vehicle boarded load, or plays the voltage change action in the vehicle converter plant.In order to save vehicle interior space, transformer often directly hangs on under-vehicle, therefore requires the folder on transformer to have very high intensity, needs to guarantee the flatness of lifting surface simultaneously.
look with a left side and look schematic diagram referring to the master who is respectively the used for rail vehicle transformer shown in attached Fig. 1 and 2, the folder of its upper end adopts the angle steel material to be made, in order to strengthen its intensity, during making, require at the inboard of angle steel folder welding reinforcement, the side view of up-to-standard angle steel folder is referring to shown in accompanying drawing 3, and the angle of angle steel folder 2 is that the angle between the 21Yu second side, first side 22 of angle steel folder 2 should be 90 °.If directly welded according to common process during reinforcement 23 in welding, welding is shunk due to weld seam later, and the angle of angle steel folder 2 is less than 90 °, be installed on transformer after its Hoisting Position will not be a plane, transformer can't be lifted on the below of vehicle.
?
Summary of the invention
the objective of the invention is to overcome the shortcoming of prior art, a kind of welding procedure of special welding platform with the angle steel folder that adopts this welding bench of angle steel folder is provided, thereby make the angle steel folder meet instructions for use after the welding reinforcement.
for achieving the above object, the technical solution used in the present invention is:
a kind of welding bench of angle steel folder, described welding bench comprise the first steel plate, with the second steel plate that described the first steel plate is fixedly connected and arranges, the angle between described the first steel plate and described the second steel plate is slightly larger than 90 °.
a kind of welding procedure that adopts the angle steel folder of above-mentioned welding bench, described welding procedure comprises the steps:
(1) described angle steel folder to be welded is positioned on described welding bench, adopts locking pliers to clamp the dual-side of described angle steel folder and make described dual-side fit tightly mutually with described the first steel plate, described the second steel plate respectively;
(2) a plurality of reinforcements are welded according to the order of sequence to the inboard of described angle steel folder;
(3) described angle steel folder is removed from described welding bench, taken off described angle steel folder.
utilization due to technique scheme, the present invention compared with prior art has following advantages: by the inboard angle be comprised of two block plates is set, be slightly larger than the welding bench of 90 °, and utilize this welding bench to be welded the angle clip part, only need be positioned on welding bench by the angle steel folder during welding and make the dual-side of angle steel folder and the dual-side of welding bench fit, at this moment again reinforcement is welded on to the inboard of angle steel folder, like this, after having welded by the angle steel folder when welding bench takes off, weld seam shrinks, angle between the dual-side of angle steel folder reduces, can offset the angle that a part is magnified on welding bench, like this, angle between the dual-side of angle steel folder can return back to 90 ° of left and right, reduced the error that this angle brings in welding process, improved the qualification rate of its production, it the is met transformer requirement of installing.
?
The accompanying drawing explanation
accompanying drawing 1 is looked schematic diagram for the master of used for rail vehicle transformer;
accompanying drawing 2 is looked schematic diagram for the left side of used for rail vehicle transformer;
the side view that accompanying drawing 3 is up-to-standard angle steel folder;
the overall schematic of the welding bench that accompanying drawing 4 is angle steel folder of the present invention;
scheme of installation when accompanying drawing 5 is welded on welding bench for angle steel folder in the present invention.
?
The specific embodiment
below in conjunction with accompanying drawing, technical scheme of the present invention is further elaborated.
shown in Fig. 4-5, a kind of welding bench of angle steel folder, this welding bench 3 comprises the first steel plate 31, be fixedly connected the second steel plate 32, the first steel plates 31 of arranging and the angle between the second steel plate 32 of the first steel plate 31, is slightly larger than 90 °.While adopting 3 pairs of angle clip parts 2 of this welding bench to be welded, welding procedure comprises the steps: at first angle steel folder 2 to be welded to be positioned on welding bench 3, adopt the dual-side of locking pliers cleat angle folder 2 and make the dual- side 21,22 of angle steel folder 2 fit tightly mutually with the first steel plate 31 and the second steel plate 32 respectively, then a plurality of reinforcements 23 are welded in a certain order to the inboard of angle steel folder 2, unclamp locking pliers after welding the clamping of angle clip part 2 is removed angle steel folder 2 from welding bench, take off angle steel folder 2.After adopting above-mentioned welding bench 3 and welding procedure to be welded angle clip part 2, the dual-side of weld seam angle of throat steel clamp part 2 shrinks to the inside, angle between the dual-side of angle steel folder 2 diminishes, the angle of angle steel folder 2 can return back to 90 ° of left and right like this, reduced the error that this angle brings in welding process, improved the production qualification rate of angle steel folder 2, it the is met transformer requirement of installing.Certainly, when making welding bench 3, in the time of should making angle between the first steel plate 31 and the second steel plate 32 be slightly larger than the angle value of 90 ° and angle steel folder 2 welding reinforcement, weld seam shrinks and the angle that reduces is close, the foozle caused in the time of can reducing as much as possible like this 2 welding of angle steel folder as far as possible.
