Hydraulic High Performance Rebar Processing Machine Steel Bar Cold Extrusion Machine

Working principle of Steel Bar Cold Extrusion Machine

Insert the steel bars to be connected into the extrusion sleeve, and squeeze the sleeve with the extrusion pliers to produce a joint formed by plastic deformation and the surface of the ribbed steel bar tightly pressed together.

Advantages of Steel Bar Cold Extrusion Machine

1. Better than the traditional lap joint and welding technology, it has the advantages of stable joint quality, no environmental impact, all-weather construction, good joint shock resistance, and low-temperature resistance.
2. The technical construction is fast, and the traditional welding method can save a lot of time on the structure.
3. The cold extrusion technology of the steel bar can reduce the engineering cost compared with the traditional steel welding connection construction.

4. The use of this machine is not affected by environmental restrictions and weather, there is no fire hazard, arc light stimulates and saves electricity.

5. Compared with lap jointing, welding, threading, and bundling processes, it has strong applicability, versatility, and low comprehensive use cost. It is a joint type with good performance and stable quality in various steel bar connection processes.

Application of Steel Bar Cold Extrusion Machine

Construction engineering, reinforced concrete structure construction, high-rise frame buildings, ordinary highways, expressways, ordinary railways, high-speed railways, tunnels, bridges, airport construction, flood control dams, earthquake-resistant buildings, marine breakwaters, and other steel connection applications.

Precautions for steel bar cold extrusion machine products

1. The steel bar is squeezed and connected, and the center spacing of the steel bar is required to be 90mm.

2. The axis of the connecting steel bar should be kept in line with the axis of the steel bar sleeve to prevent eccentricity and bending.

3. The connection quality must be implemented in accordance with the relevant regulations of the specification.

Operating Instructions for Rebar Cold Extrusion Press

1. The extrusion force should be calibrated before using the steel bar cold extrusion equipment (the complete set of steel bar cold extrusion pliers, ultra-high pressure electric hydraulic pump, etc.) (the size of the extrusion force is controlled by the reading of the oil pressure gauge).
2. It is necessary to check in advance whether the extrusion die and the cold extrusion sleeve of the steel bar are matched with the ribbed steel bar. The stamping die should be marked with the corresponding cold extrusion specification mark of the steel bar. The extrusion force and the width of the extrusion die used in the extrusion operation, the indentation diameter or the fluctuation range of the length of the cold extrusion sleeve of the steel bar after extrusion, as well as the number of extrusion passes, shall meet the technical parameter requirements determined by the technical provider of the cold extrusion sleeve of the steel bar.
3. The matching ribbed steel bar and steel bar cold extrusion sleeve should be checked before use, and the unclean parts (rust, sediment, oil, etc.) of the crimping part should be cleaned up; it is necessary to check whether the steel bar cold extrusion sleeve is If it is found that the steel bar is bent, horseshoe-shaped or the longitudinal rib size is too large, it should be corrected or ground with a hand-stretched grinding wheel.
