Abstract

The utility model relates to a fixture device for the extension of a run-on plate and an arc blowout plate. The fixture device is characterized by comprising two L-shaped clamping plates (1), wherein the L-shaped clamping plates (1) are arranged opposite to each other in parallel, and are connected through a spring bolt (2); small plates I (3) are horizontally arranged at the upper ends of vertical plates of the L-shaped clamping plates (1); small plates II (4) are arranged on the edges of horizontal plates of the L-shaped clamping plates (1); and small plates III (5) are arranged at the bottoms of the horizontal plates of the L-shaped clamping plates (1). The fixture device is ingenious in structure and high in operability, has a remarkable effect, and can be used for welded H-shaped components in various specifications, a principle is clear, and remarkable effects can be created; and compared with the conventional manufacturing method, the fixture device has the advantage that the material utilization rate of the run-on plate and the arc blowout plate can be increased to 43.8 percent.

Description

Draw arc-extinguishing plate and prolong grip device

Technical field

The utility model relates to a kind of arc-extinguishing plate that draws and prolongs grip device, is mainly used in the H type structure manufacture process that the main weld welding is drawn, arc-extinguishing plate.Belong to steel construction processing and fabricating technical field.

Background technology

When welded H type member main weld, for with the remove defects of the starting the arc, the arc that falls in the main weld scope, often need to add draw, arc-extinguishing plate, carry out capping according to present processing technology main weld needs after filling is complete with submerged-arc welding, for the appearance of weld that makes the submerged-arc welding capping is attractive in appearance, need to add for the drawing of submerged arc welding machine, arc-extinguishing plate.

According to the feature of machine head of submerged-arc welding machine, add the appearance and size that is located at drawing on the H shaped steel wing plate, arc-extinguishing plate and be: long 150mm, wide 80 * 2+ web thickness; Adding the appearance and size that is located at drawing on the web, arc-extinguishing plate is: long 150mm, wide 80mm.According to code requirement draw, arc-extinguishing plate draws length and is at least 80mm.

A H type member needs eight approximately and draws arc-extinguishing plate, and take a wing plate specification as 40mm, the web specification is that the H type member of 20mm calculates, and the required arc-extinguishing plate area that draws is 0.156m ², weight is 24.5kg, along with the increase of quantities, causes drawing, arc-extinguishing plate and consumable material also can increase thereupon.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of arc-extinguishing plate that draws to prolong grip device, reduce be used for drawing, the spillage of material of arc-extinguishing plate, be used in draw, the arc-extinguishing plate stock utilization gets a promotion.

The purpose of this utility model is achieved in that a kind of arc-extinguishing plate that draws prolongs grip device, it comprises two L-type clamping plate, described two L-type clamping plate are arranged side by side relatively, and connect by spring bolt, riser upper end at described two L-type clamping plate all has been horizontally disposed with platelet I, level board edge at described two L-type clamping plate is equipped with platelet II, is equipped with platelet III in the level board bottom of described two L-type clamping plate.

During work by clamping front end segment run-on tab, make the length of whole device reach former run-on tab length, after use finished, extension fixture is detachable also can be reused, short because of the former run-on tab of front end segment run-on tab Length Ratio, reach the purpose of saving the run-on tab material with this.

Compared with prior art, the beneficial effects of the utility model are:

The utility model device construction is ingenious, and principle is distinct, and is workable, remarkably productive, can be in order to the welded H type member of plurality of specifications, and the benefit of acquisition is very obvious, compares with conventional preparation method, can improve to draw the arc-extinguishing plate stock utilization and reach 43.8%.

The specific embodiment

Referring to Fig. 1-Fig. 3, the utility model relates to a kind of arc-extinguishing plate that draws and prolongs grip device, mainly formed by two L-type clamping plate 1, described two L-type clamping plate 1 are arranged side by side relatively, and connect by spring bolt 2, all be horizontally disposed with platelet I 3 in the riser upper end of described two L-type clamping plate 1, described platelet I3 is used for clamping web segment and draws arc-extinguishing plate, level board edge at described two L-type clamping plate 1 is equipped with platelet II 4, and described platelet II 4 is used for clamping segment wing plate run-on tab; Level board bottom at described two L-type clamping plate 1 is equipped with platelet III 5, is used for lifting holding segment wing plate run-on tab.

Concrete operation step is as follows:

1. segment is drawn, arc-extinguishing plate is welded to H type member termination, method and tradition add that to draw the arc-extinguishing plate method identical;

2. the spring bolt that will draw, arc-extinguishing plate prolongs grip device is unscrewed, can free-extension, and degree of unscrewing can be determined according to web thickness;

3. pull open draw, two clamping plate that arc-extinguishing plate prolongs grip device, device is enclosed within segment draws on the arc-extinguishing plate;

4. tighten draw, spring bolt that arc-extinguishing plate prolongs grip device, make it grip segment and draw arc-extinguishing plate, get final product;

5. carry out follow-up submerged-arc welding procedures.

Claims

1. one kind is drawn arc-extinguishing plate prolongation grip device, it is characterized in that it comprises two L-type clamping plate (1), described two L-type clamping plate (1) are arranged side by side relatively, and connect by spring bolt (2), riser upper end at described two L-type clamping plate (1) all has been horizontally disposed with platelet I(3), level board edge at described two L-type clamping plate (1) is equipped with platelet II(4), be equipped with platelet III(5 in the level board bottom of described two L-type clamping plate (1)).
