Description

Technical Field

[0001] This utility model belongs to the technical field of roll welding machines, and particularly relates to a roll welding machine for steel cages. Background Technology

[0002] A reinforcing cage is a precast building material made of welded steel bars, typically used in column-shaped or strip-shaped concrete members. Its core structural feature is that reinforcing bars are placed under the surface of the member exposed to air, while the central part requires no reinforcement, forming a ring-shaped support structure through independent prefabrication. It is mainly used in pile foundations, bridge and culvert construction, and high-rise building foundation construction. By combining with poured concrete, it bears tensile strength, compensating for the insufficient tensile strength of concrete. The fabrication of reinforcing cages requires the use of a welding machine to perform the welding operation.

[0003] For example, patent CN215588117U discloses an automatic roll welding machine for processing rebar cages, including a base, a rotating feed ring, a drive motor, a connecting shaft, and a synchronous separating roller. The rotating feed ring is mounted on the base, and the drive motor is connected to the rotating feed ring on the base. The connecting shaft is connected to the center of the rotating feed ring. This utility model relates to the field of building material processing technology. This automatic roll welding machine for processing rebar cages has a simple structure. Based on the current automatic roll welding machines, it introduces a powered automatic wire feeding structure, which allows the rebar used for transverse reinforcement to have a certain linear speed during conveying, reducing the tensile force generated when the reinforcement rebar is wound onto the rebar cage. On the one hand, it increases the stability of the welded connection, and on the other hand, it matches the rotation speed of the roll welding, avoiding affecting the bonding effect of the rebar connection during roll welding.

[0004] Existing rebar cage welding machines require frequent replacement of limit plates when welding rebar cages of different diameters, making operation cumbersome. Therefore, we propose a rebar cage welding machine. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a roll welding machine for steel cages, which facilitates roll welding operations on steel cages of different diameters.

[0006] In view of this, the present invention provides a welding machine for rebar cages, including a base frame, a limiting frame welded to one end of the base frame, a limiting plate installed on the inner wall of the limiting frame, a central column fixedly connected to the outer wall of the limiting plate, an adjusting push cylinder installed on the outer wall of the central column, a push block installed at the output end of the adjusting push cylinder, an adjusting rod hinged to the outer wall of the push block, a sliding seat hinged to the top of the adjusting rod, an active rod hinged to the connection between the sliding seat and the central column, a support plate fitted into the top of the sliding seat, a linkage rod hinged to the outer wall of the active rod, a driven rod hinged to one end of the linkage rod and hinged to the outer wall of the central column, and the top of the driven rod movably connected to... The support plate is attached to the bottom end. A limiting groove is formed on the outer wall of the support plate. A sliding groove is formed at the connection between the limiting plate and the support plate. A pressing cylinder is installed in the sliding groove. A pressing roller is installed at the output end of the pressing cylinder. A rotary motor is installed on the outer wall of the limiting frame. A gear is installed at the output end of the rotary motor. A rotary gear ring that meshes with the outer wall of the limiting frame is engaged with the meshing surface of the gear. A feeding roller is installed on the side wall of the rotary gear ring. A welding base is installed on the outer wall of the rotary gear ring. An adjusting screw is installed on the inner wall of the welding base. A welding seat is threaded to the outer wall of the adjusting screw. A laser welding head is installed on the outer wall of the welding seat.

[0007] Based on the above structure, the adjustment of the push cylinder causes the push block to slide along the outer wall of the central column. The sliding of the push block drives the active rod to rotate through the adjustment rod. The rotation of the active rod drives the driven rod to rotate synchronously through the linkage rod. Through the parallel and equal active rod and driven rod, the support plate is driven to slide along the groove of the sliding groove, thereby realizing the adjustment operation of the diameter of the steel cage.

[0008] Preferably, the driving rod and the driven rod are parallel and equal in length. In this embodiment, the parallel and equal driving rod and the driven rod facilitate the stable movement of the support plate.

[0009] Preferably, the support plate forms a sliding structure with the sliding groove through the active rod and the driven rod. The support plate is perpendicular to the limiting plate. In this embodiment, the sliding of the push block drives the active rod to rotate through the adjusting rod. The rotation of the active rod drives the driven rod to rotate synchronously through the linkage rod, thereby driving the support plate to slide along the groove of the sliding groove, so as to realize the adjustment operation of the diameter of the steel cage.

[0010] Preferably, the support plate is provided in eight sets, and the positions of the eight sets of support plates are distributed in a circular manner at equal angles with respect to the active rod. In this embodiment, by providing the eight sets of support plates, it is beneficial to support the reinforcing bars and avoid deformation of the reinforcing bars, which could lead to incomplete welding of the reinforcing cage during welding.

[0011] Preferably, the center of the rotating gear ring coincides with the center of the limiting disk. In this embodiment, it is convenient for the rotating motor to drive the rotating gear ring to rotate around the center of the limiting disk through the gear, thereby performing the roll welding operation on the steel cage.

[0012] Preferably, a working motor is installed on the outer wall of the base frame, a working screw is installed at the output end of the working motor, a drag base is threadedly connected to the outer wall of the working screw, an installation plate is installed on the outer wall of the drag base, and an installation clamp is installed on the outer edge of the installation plate. In this embodiment, the working motor drives the installation plate at the top of the drag base to slide through the working screw, thereby dragging the steel bar to move.

[0013] Preferably, the central axis of the mounting plate coincides with the central axis of the limiting plate, and the mounting clamps are provided in eight sets. In this embodiment, the bending of the reinforcing cage during roll welding is avoided, which would affect the overall structural strength of the reinforcing cage.

[0014] The beneficial effects of this utility model are: 1. This welding machine for rebar cages, by setting up a support plate, adjusts the working of the push cylinder to drive the push block to slide along the outer wall of the central column. The sliding of the push block drives the active rod to rotate through the adjusting rod. The rotation of the active rod drives the driven rod to rotate synchronously through the linkage rod. Through the parallel and equal active rod and driven rod, the support plate is driven to slide along the groove of the sliding groove, thereby realizing the adjustment operation of the diameter of the rebar cage.

[0015] 2. This rebar cage welding machine, by setting up a laser welding head and a feeding roller, adjusts the screw to rotate, which drives the laser welding head to approach the rebar through the welding seat. Then, the working motor drives the mounting plate at the top of the base to slide through the working screw, dragging the rebar. At the same time, the rotary motor drives the rotating gear ring to rotate through the gear. The rotating gear ring rotates the laser welding head and the feeding roller to rotate synchronously, thereby performing the rebar cage welding operation. Attached Figure Description
