Rebar Extrusion Press Machine is to be connected to the steel into the extrusion sleeve, squeeze the sleeve with a squeeze force, so that the plastic deformation and ribbed steel surface tightly formed by the joint. The technology with the traditional lap, welding technology compared with the quality of a stable and reliable joint, I plant extrusion equipment from the ultra-high pressure pump station, high pressure tubing and squeeze clamp, die supporting the use of together to complete the extrusion connection.
JYJ-32/40 Rebar cold extrusion press machine a full set of equipment include: a high-pressure pump station, a hydraulic clamp, a die, 5M high-pressure tubing two, a set of tools.
The purpose of the project: in the highway bridge project is worthy of popularization and application of steel extrusion machine technology in the pile foundation project to make the steel cage to achieve the overall docking, can improve the vertical cage cage to speed up the pile into the speed, , The collapse of the accident occurred, to improve the quality of the pile in the bridge pier and column, cover beams and ordinary reinforced concrete beams, plates to achieve the main bar cold pressure docking, steel joints can be avoided and the joints bent steel bending difficult There is welding stress problem, reduce the electricity load, improve the quality of joints, to speed up the construction progress. cold extrusion press machines Applicable to industrial and civil construction (structure) buildings, high-rise buildings.
Sleeve diameter mm
When one of the following conditions occurs, the extrusion force of the extruder should be calibrated: a. New extrusion equipment before use; b. Old extrusion equipment after overhaul; c. Oil pressure table damaged or strong vibration;
(1)Sleeve indentation abnormal and can not find other reasons; e. Extrusion equipment used for more than one year; f. The number of extruded joints is more than 5000.
(2) equipment before and after the disassembly process, the high-pressure tubing at both ends of the joints and crimping pliers, valve inlet and outlet joints should be kept clean, and should be promptly sealed with a special method. Ultra-high pressure tubing bending radius of not less than 250mm, buckle joints can not be reversed, and shall not have a dead bend.
(3) Extruder The high pressure hose of the hydraulic system shall not be dragged, bent and scored by sharp objects.
(4) die, casing and steel should be used in conjunction with each other, the mold should be connected to the corresponding steel bar mark.
(5) Preparation before extrusion:
A.Steel ends of the rust, mud, oil and other debris should be clean and clean;
B.Steel bars and sleeves should be first test sets, when the steel horseshoe, bending or vertical rib size is too large, should be pre-corrected or polished with a grinding wheel; different diameter steel sleeve can not string with;
C.The end of the steel should be drawn positioning mark and check mark, positioning mark and the end of the steel should be the distance between the length of the sleeve, check the mark and positioning mark the distance should be 20mm;
D.Check the situation of extrusion equipment, should be tested pressure, meet the requirements before the operation. (6) extrusion operation should meet the following requirements:
E.cold extrusion machine should first squeeze one end of the sleeve on the ground, in the construction area to be inserted into the steel and then squeeze the other end of the sleeve.
F.Crimping pliers in place, should be aligned sleeve indentation mark, and should be perpendicular to the axis of steel; c. The extrusion sequence should start from the middle of the sleeve and gradually squeeze to the end;
G.The squeeze operator shall not arbitrarily change the squeezing force,the number of crimp connections or the order of extrusion.
H.After the operation should be finished finished products, sleeves and die, clean up the site, cut off the power, lock the switch box, the final extrusion press and squeeze clamp to the designated location.
