Abstract

The invention provides an automatic reducing device of a seam welder, relating to a reducing mechanism of a cement tube reinforcement cage welding device, which can adapt a continuous vertical rib feeding mode. The automatic reducing device comprises a reducing cylinder and a reducing cylinder control mechanism, wherein the reducing cylinder is arranged on a main disk and used for driving a welding head to move radically, and the reducing cylinder control mechanism is arranged on a tie bar trolley and used for controlling the reducing cylinder to move axially. The main disk is provided with a central hole; the reducing cylinder comprises a reducing screw rod, a rear disk, a front disk, a chain 1, a steering wheel group 1, a chain 2, a steering wheel group 2 and a connection link. The reducing cylinder control mechanism comprises a reducing control rod the cross section of which is a hexagon, a clutch and a driving mechanism; the driving mechanism is fixedly connected to the trolley; and the reducing control rod is connected with the driving mechanism through the clutch. After the reducing control rod of the invention is meshed with the reducing screw rod,, the reducing control rod can drive the reducing screw rod to rotate when rotating; the rotation of the reducing screw rod drives the front disk and the rear disk to move axially; and the axial movement of the front disk and the rear disk can drive the welding head to move radically via the chain 1 and the chain 2, thereby realizing reducing.

Description

technical field [0001] The invention relates to a diameter-changing mechanism of cement pipe-making steel bar skeleton welding equipment. Background technique [0002] At present, domestic drainage pipes are mainly reinforced concrete drainage pipes. The production of reinforced concrete drainage pipes is mainly divided into two steps: steel skeleton production and concrete product molding. Among them, there are two ways to make the steel skeleton: 1. Manual binding; 2. Welding with special equipment. The steel frame is divided into longitudinal bars and ring bars. In the prior art, the processing process of the steel bar frame welding equipment is: first straighten and cut the steel wires to make longitudinal bars, and arrange a certain number of longitudinal bars on the corresponding circumference. All the longitudinal bars rotate around the center, wind the ring bars to the longitudinal bars, and form the required pitch, and perform resistance welding where the longitud...
