Description

A kind of steel reinforcement cage welding tooling and its fixed electrode

Technical field

The utility model relates to a kind of steel reinforcement cage welding tooling and its fixed electrodes, belong to pattern welding equipment technical field.

Background technique

The component insides such as all kinds of stakes, column, beam in construction project need to be arranged framework of steel reinforcement (being commonly called as steel reinforcement cage) to constrain Concrete, to guarantee the globality of concrete component.For example, being needed in the work progress of bridge and skyscraper bored concrete pile Steel reinforcement cage is placed in ground stake holes to enhance the tensile property of bored concrete pile.The steel reinforcement cage includes that multiple extending directions are consistent It main reinforcement and is arranged vertically with main reinforcement extending direction or spiral circular stirrup, stirrup is fixed on the outer of main reinforcement with welding manner Steel reinforcement cage can be divided into rectangular steel reinforcement cage, round steel reinforcement cage and other shapes of steel according to the distribution form of main reinforcement by week or inner circumferential Muscle cage is specifically determined according to Components Shapes such as stake, column, beams.

Under normal conditions, the production needs of steel reinforcement cage are completed by specific welding assambly, and common specific welding assambly is Seam welder, makees electrode to fix copper ring (disk), and the main reinforcement rod iron (lengthways main steel bar) of steel reinforcement cage is overlapped on fixed copper ring (disk) On, drive float electrode to carry out point-to-point welding with the cylinder of main reinforcement rod iron equivalent amount, or with another electrode edge Fixed copper ring (disk) makees rotation to be welded.Individually below by taking rectangular steel reinforcement cage and round steel reinforcement cage as an example, to seam welder Structure is briefly described.

Referring to FIG. 1 to FIG. 2, the seam welder schematic diagram as shown in the figure to be welded in the prior art for rectangular steel reinforcement cage is being rolled The one end main shaft 1-1 fixed installation of welding machine 1 is rectangular to lead muscle disk 2, and the main shaft 1-1 other end assembles rectangular copper dish 3 by liner disk 1-2 (rectangular copper dish 3 are used as fixed electrode), and block 4 is installed in rectangular copper dish 3, insulation is equipped between block 4 and rectangular copper dish 3 Pad 6,5 one end of main reinforcement rod iron pass through the rectangular pilot hole 2-1 led on muscle disk 2, and the other end is overlapped in rectangular copper dish 3, pass through peace Block 4 in rectangular copper dish 3 is to the positioning of main reinforcement rod iron 5 (block is used as main reinforcement rod iron workpiece locating mechanism).Due to rectangular It is longer to lead distance between muscle disk 2 and rectangular copper dish 3, the intermediate position under its own gravity of main reinforcement rod iron 5 is sagging, causes to lead 5 end of concrete steel stick tilts, and not only prevents main reinforcement rod iron 5 from contacting with the rectangular fitting completely of copper dish 3, but also two neighboring block The card slot that 4 edges are formed is difficult to realize the positioning action to main reinforcement rod iron 5.

Referring to Fig. 3~Fig. 5, the seam welder schematic diagram as shown in the figure in the prior art for round steel reinforcement cage, in seam welder 1 One end of main shaft 1-1 circle be fixedly mounted lead muscle disk 8,10 (positioning disk of positioning disk 9 and round copper dish is fixedly mounted in the other end 9, the round combination of copper dish 10 is as fixed electrode), and make by insulating bushing 7 main shaft 1-1, the circle of positioning disk 9 Yu seam welder 1 Shape copper dish 10 are isolated, and 5 one end of main reinforcement rod iron passes through the round pilot hole 8-1 led on muscle disk 8, and the other end is overlapped on 9 He of positioning disk In round copper dish 10, by the card slot of 9 edge of positioning disk is arranged in, to the positioning of main reinforcement rod iron 5, (card slot is used as main reinforcement rod iron work Part positioning mechanism).Similar with aforementioned FIG. 1 to FIG. 2, which also will appear because circle leads muscle disk 8 Distance is longer between positioning disk 9 and round copper dish 10 leads to that the intermediate position of main reinforcement rod iron 5 is sagging, end tilts, main reinforcement rod iron 5 It cannot be contacted with the round fitting completely of copper dish 10,9 edge card slot of positioning disk is difficult to realize the work of the positioning to main reinforcement rod iron 5 With.

It can be seen that in the prior art, it is either rectangular, or the seam welder of round steel reinforcement cage, all there is certain lack It falls into, specifically: longer due to leading distance between muscle disk and copper dish, main reinforcement rod iron is under its own gravity under intermediate position It hangs down, causes main reinforcement rod iron end to tilt, on the one hand main reinforcement rod iron can be prevented to contact from being bonded completely with copper dish, pole in welding process It is also easy to produce electric spark, because electric spark is to the corrosiveness of copper dish, reduces the electric conductivity of copper dish, rosin joint, dry joint etc. is caused to lack It falls into, has seriously affected the welding quality of steel reinforcement cage, so periodically must integrally replace to copper dish, thus increased steel reinforcement cage Production cost；After another aspect main reinforcement rod iron end tilts, workpiece locating mechanism cannot reliably position main reinforcement rod iron, difficult To guarantee that range error is in control range between main reinforcement rod iron, the installation accuracy of steel reinforcement cage in work progress is reduced.
