Description
Technical field
The present invention relates to a kind of coating equipment for automatic casing of prestressing steel bar, relate in particular to and a kind ofly length is not more than 10 meters short size prestressed steel bar carries out the coating equipment for automatic casing that non-integral coats.
Background technology
Length is not more than the screw thread that there is certain size length at 10 meters short size prestressed steel bar two ends, needs the exposed portions serve screw thread for coating the prestressed steel bar two ends that finish as requested.At present, domestic coating equipment for automatic casing of prestressing steel bar all is the long size prestressed steel bars at rolling, adopts and the similar principle of cable equipment, and techniqueflow is links such as rod iron uncoiling, oiling, coating, rolling.Domestic research and development to this equipment improve and also all concentrate on uncoiling, coiled equipment improves, and make the equipment can be to aspects such as big length wire rod, high-speed smooth operations.
At present, at home at the oiling of short size prestressed steel bar, the manufacturing that coats fully-automatic equipment or blank, because it is that part coats that the prestressed steel bar plastic bushing is coated, equipment on the market all can not be satisfied the demand at present, so what producer adopted the oiling of prestressing without bondn rod iron, sleeve pipe coating work is the way of artificial oiling, sleeve pipe, operating needs great amount of manpower, and working environment is relatively poor.
Summary of the invention
Coating to short size prestressed steel bar is compared with the coating of long size prestressed steel bar, has following several difficult point:
1. serialization operation---because short size rod iron will cut after coating automatically, blanking, this makes and must leave certain interval between the rod iron and rod iron on the production line, can not have the draw power that gives as uncoiling and coiled equipment in the whole coil rod coating assembly line between prestressed steel bar, need on equipment, be equipped with automatic traction device prestressed steel bar.
2. cutting link---long size rod iron coats and does not have the cutting link.When producing weak point size prestressed steel bar, because certain clearance between rod iron, this gap has plastics to be connected, so need carry out automatic cutting and separating to coating good rod iron on the production line.Because the gap between rod iron is not too large, so but the dimensional accuracy of cutting directly influences stablizing of production line and problem is carried out in the serialization of production.
3. the prestressed steel bar threaded portion is handled---and short size prestressed steel bar two ends are the screw thread of certain-length, and the screw thread of certain size need be exposed in the rod iron two ends after the coating.If use extrusion apparatus to carry out integral coating to rod iron, so how this part the coating sleeve pipe that need remove being handled also is a great problem, to guarantee that at first double thread part sleeve pipe cuts, form the cutting trace, and the prestressed steel bar threaded portion is not damaged; The size of exposing threaded portion after its less important assurance cutting can conform to specification requirement; At last, the position of cutter sweep in equipment selected also will directly influence the speed of service of a whole set of production procedure.
4. oiling link---prestressing without bondn rod iron need be coated with one deck special protection grease to the rod iron surface before sleeve pipe coats, how to guarantee that grease does not drop onto device external in the machine running process, assurance equipment is clean and tidy as new, and this is a problem should considering to the device design time.
In order to realize work such as automatic oiling, automatic casing coating to short size prestressed steel bar, the present invention has produced a cover coating equipment for automatic casing, it can carry out oiling to short size prestressed steel bar, sleeve pipe coats, and equipment adopts PLC programmable controller system, the whole-course automation operation.
The technical solution adopted for the present invention to solve the technical problems is:
Add feed draw-gear and draw-gear on equipment, the distance of these two draw-gears guarantees to be subjected to the tractive force effect at each the root prestressed steel bar on the production line in running with this less than the length dimension of prestressed steel bar.
The oiling station employing is carried out oiling to the way that grease heats spray to prestressed steel bar.Grease in the constant temperature fuel tank is heated and is in a liquid state, pressure oil pipe through being connected with oil pump is transferred to heating spray fuel tank and finishes spray operation to prestressed steel bar, the liquid fat that drips from prestressed steel bar is back to the constant temperature fuel tank at last, forms a process capable of circulation.Oiling station is the semi-hermetic device, sprays excessive grease and can recycle and do not cause waste, and Zhuan Zhi seal can guarantee the working site cleaning again simultaneously.
Cooling device adopts the cooler bin that can vertically move back and forth, and wheel apparatus is walked in its bottom, and under the drive of mobile motor, cooler bin can vertically move repeatedly.Take the advantage of such way to make complete equipment to coat,, then only need the relative device adjustment of each device on the equipment is got final product if change the prestressed steel bar of another kind of length to the different length prestressed steel bar.
Be furnished with draw-gear and motor thereof on the cutter sweep; Be clamping device behind the draw-gear, its effect is keep rod iron when the prestressed steel bar sleeve pipe is cut stable; It behind the clamping device cutting part, cutting part is divided into three groups: first group is preceding shutoff cutter sweep, can carry out cutting and separating to the rod iron that links to each other: the back is front pressure slot cutter sweep and rear pressure slot cutter sweep for two groups, can form the impression groove to the cutting of prestressed steel bar threaded portion sleeve pipe, make the part sleeve pipe that is coated on two thread segments under manual action, to open with overall separation.The uniqueness of cutter sweep is and can carries out separation cuts and the cutting of screw thread indent to rod iron simultaneously, when one end of prestressed steel bar on the production line runs to the rear pressure slot cutter sweep, electromagnetic sensor sends signal, clamping device on the cutter sweep clamps prestressed steel bar, simultaneously cutting part under the pneumatic means effect with production line on prestressed steel bar advance in the same way with the identical speed of service, three groups of cutting parts carry out cutting work when advancing, after cutting finished, cutting was next time prepared in the position that cutting part can be returned to again under the pneumatic means effect before the motion.Position between three groups of cutting parts on the cutter sweep can be adjusted, and the indent length dimension that makes the prestressed steel bar two ends form can reach instructions for use.
