The load-bearing capacity of the inverted wire drawing machine varies according to the model. The larger the diameter of the processed steel bar, the larger the corresponding load-bearing capacity of the inverted wire drawing machine. When drawing steel bars, the force borne by the equipment is different according to the different diameter reduction of the steel bars. The models and sizes of the inverted wire drawing machine are different. When drawing steel bars, the load-bearing capacity of the wire drawing machine frame should be greater than the tension required for the steel bar diameter reduction, so as to ensure that the steel bar diameter reduction is not deformed or tilted when the wire drawing machine frame is pulled. When selecting the chain, it should be purchased strictly according to the design data, and the tension of the chain should be greater than the tension required for the steel bar diameter reduction. The 800 type inverted wire drawing machine can use ordinary ring chain, and the diameter of the ring chain steel bar is 12-16mm. The chain of the 1200 type inverted wire drawing machine uses a double-group chain. The chain has a load-bearing capacity of up to 40 tons, which can meet the tension required for processing a diameter of 20mm.
What should be done before the inverted wire drawing machine is put into operation? 1. Before starting the inverted wire drawing machine, make sure that the gear oil is filled in the reducer;
2. Before starting the inverted wire drawing machine, the equipment must be fixed first, and a solid foundation must be required according to the anchor holes reserved on the equipment to avoid vibration. 3. It is required to make the wire drawing axis symmetrical with the center line of the die hole through debugging, so as to make the stress of the wire and the wire drawing die uniform and avoid damage. In addition, frequent starting and stopping should be avoided, because the friction caused by the tensile stress at the start of drawing is much greater than the friction during normal drawing, which will inevitably increase the wear of the die.
4. Some of the shortcomings of the wire can also be avoided through corresponding measures, mainly involving surface pretreatment and heat treatment, which are for wires used for drawing; 5. The wire drawing box of the inverted wire drawing machine should be filled with wire drawing powder to increase the lubricity of the steel bars. 6. Before starting the machine, check that the air, water, and electrical circuits of the inverted wire drawing machine are unobstructed. Only when everything is normal can the machine be started.
