Description
Technical Field
The invention relates to the technical field of construction equipment for processing steel bars in building construction, in particular to a steel bar upsetting machine for cold upsetting processing operation of a steel bar connection end part.
Background
In a concrete building structure, the mechanical connection of reinforcing steel bars has the advantages of convenient installation, quick connection and high joint performance, and the upsetting straight thread connection of the reinforcing steel bars is an important method.
The steel bar upsetting machine is a special machine for upsetting the end of a steel bar and mainly comprises a bearing frame, an oil cylinder, a clamping die, a forming die, an upsetting die, a hydraulic pump station and the like. The single-piston single-oil-cylinder four-column spring compression wedge block type upsetting machine is a single-cylinder wedge block type upsetting machine for short, and is a product which is most applied in the market due to small volume, light weight, convenient movement and low cost. The single-cylinder wedge upsetter provides a sufficiently large clamping force in a small-sized frame using the wedge principle, but this apparatus still has significant disadvantages: firstly, the size precision of the processed steel bar upsetting head is poor, because the structure of the existing machine equipment uses spring force to press a wedge block to pre-clamp the steel bar, and the springs can only provide hundreds of kilograms of pressure at most and are not enough to press the wedge block to the position of completely clamping the steel bar, the acting force of an upsetting oil cylinder for pushing the steel bar during upsetting is required to push the wedge block to move to increase the clamping force to clamp the steel bar, therefore, when the upsetting head presses the steel bar to advance, an invalid stroke which can not deform the end of the steel bar until the steel bar is completely clamped by the wedge block is provided in the upsetting action of an oil cylinder piston which is fixed with the upsetting head, and after the steel bar is completely clamped by the wedge block, the advancing distance of the upsetting head is an effective stroke which can not compress the end of the steel bar and deform and expand the steel bar, because the pressures required for clamping the steel bars with different tensile strengths and different diameters are different, the invalid stroke for clamping the steel bar in, even if the shape deviation and the strength deviation of the steel bars with the same diameter can also cause the difference of the invalid strokes of the piston and the upset head, the machine can only set one positioning position for the steel bars with one specification, so the difference of the invalid strokes directly causes the difference of the valid strokes, namely the axial deformation of the processed steel bars is also different, finally the accuracy of the size of the upset head formed by the steel bar upsetting processing is lower, and certain quality hidden trouble is brought to a steel bar connecting joint; secondly, because the full stroke of the upsetting operation of the piston of the oil cylinder of the upsetting machine comprises an effective stroke and an ineffective stroke, the ineffective stroke is even close to 1/2 of the length of the effective stroke, and the upsetting processing period of the oil cylinder comprises upsetting and returning to a set position, the ineffective stroke can prolong the processing period, while the oil cylinder of the upsetting machine is usually a large oil cylinder with hundreds of tons of output force, even if a large-flow pump is used, the metal deformation speed is not too high, the moving speed of the piston is relatively slow, so the upsetting processing period is relatively long, and the working efficiency is low; when the steel bar is processed by upsetting, the steel bar clamping die in the wedge blocks clamps the steel bar every time, tooth tips of the die can be embedded into the surface of the steel bar, after the upsetting action is finished, the piston returns, the upsetting head resets, and the wedge-shaped clamp is opened, the self weight of the steel bar cannot overcome the binding force of the steel bar embedded into the tooth tips of the die, the die cannot be automatically separated from the steel bar, the clamping die on one side can be adhered to the steel bar, the steel bar is driven to move, the steel bar is required to be taken out, the steel bar is required to be knocked to separate from the die, and the production efficiency is.
