Problems solved by technology

In the face of a large demand for special-shaped concrete pipes in the market, domestic concrete and cement product enterprises have introduced foreign special-shaped pipe steel frame seam welding machines, but due to the monopoly position of foreign countries, the product prices are extremely expensive, which increases the burden on enterprises
In addition, the currently imported special-shaped steel bar frame seam welding machine can only produce circular tube steel bar frame and square tube steel bar frame, and cannot produce more complex special-shaped tube steel bar frames.
[0003] The patent No. 201010548189.X is an invention patent "a traction type seam welding machine". Its diameter-changing mechanism is driven by an electric motor, so when changing the diameter, all welding stations move the same distance, and can only process circular tube steel skeletons , it is impossible to produce special-shaped steel skeletons; in order to realize the synchronous rotation of the traction faceplate and the main faceplate, two sprockets on a square steel are used to drive the traction faceplate and the main faceplate respectively, and the method of mechanical synchronization is easy to cause damage to the sprockets; for Clamp the longitudinal bars and drag the axial displacement of the steel frame. The traction faceplate is equipped with multiple cylinders, resulting in a complex structure and high cost. Once there are cylinders that do not clamp the longitudinal bars, it is easy to cause the failure of dragging the axial displacement of the steel frame.

Embodiment Construction

[0038] Such as figure 1 , 2 As shown, the automatic variable-diameter roll welding machine for special-shaped steel bar skeletons of the present invention includes a support mechanism 1 , a diameter-reducing mechanism 2 , a traction mechanism 3 , a driving mechanism 4 and a welding mechanism 5 . The support mechanism 1 is used to support the weight of the longitudinal reinforcement, the variable diameter mechanism 2 is used to change the relative position of the welding seat 25 relative to the center of the main face plate 24, so that the longitudinal reinforcement 324 forms the required steel skeleton cross-sectional shape, and the traction mechanism 3 is used to drag The moving reinforcement skeleton moves longitudinally and realizes the synchronous rotation of its traction faceplate 32 and the main faceplate 24 of the variable diameter mechanism 2. The driving mechanism 4 is used to drive the main faceplate 24 of the variable diameter mechanism 2 to rotate at a constant spe...

Abstract

The invention relates to an automatic variable-diameter seam welder for steel reinforcement frameworks of special pipes, comprising a support mechanism, a diameter changing mechanism, a drawing mechanism, a driving mechanism and a welding mechanism, wherein the support mechanism is used for supporting the weight of longitudinal bars; the diameter changing mechanism is used for changing the position of a welding seat, relative to the center of a main disk chuck, so as to form the required cross section shape of the steel reinforcement framework; the drawing mechanism is used for dragging the steel reinforcement framework to move longitudinally and achieving synchronous rotation of a drawing disk chuck and the main disk chuck of the diameter changing mechanism; the driving mechanism is used for driving the main disk chuck of the diameter changing mechanism to rotate at uniform speed; and the welding mechanism is used for realizing welding of annular bars and longitudinal bars of the steel reinforcement framework. The seam welder for the steel reinforcement frameworks of the special pipes can be used for machining steel reinforcement frameworks of special pipes with different cross section shapes, including steel reinforcement frameworks of circular pipes, oval pipes, rectangular pipes, oblong pipes, ovoid pipes, single-circle arched pipes, three-circle arched pipes, four-circle arched pipes and V-shaped pipes, and is convenient to use and high in production efficiency.

Description

technical field [0001] The invention relates to a production machine for reinforced concrete products, more specifically, an automatic variable-diameter roll welding machine for special-shaped steel bar skeletons. Background technique [0002] At present, the automatic variable-diameter seam welding machine independently produced in my country can only be used to process circular steel bar skeletons with different diameters, and has no ability to produce special-shaped steel bar skeletons. In the face of a large demand for special-shaped concrete pipes in the market, domestic concrete and cement product companies have introduced foreign special-shaped pipe steel frame seam welding machines, but due to the monopoly position of foreign countries, the product prices are extremely expensive, which increases the burden on enterprises. In addition, the currently imported special-shaped steel bar frame seam welding machine can only produce circular tube steel bar frame and square t...
