Description

Technical Field

[0001] The utility model relates to a feeding device for a bar heating furnace, in particular to a pushing device for feeding anchor chain bars into a medium frequency induction heating furnace, belonging to the technical field of linear conveying devices. Background Art

[0002] Anchor chains are crucial components for the safety of ships and marine engineering equipment. They are composed of linked links. These links are manufactured in an anchor chain manufacturing unit consisting of a bar heater, ring benders, flash welders, weld deburrs, and crossbar presses. The first unit in the unit is a bar heater that integrates both bar conveying and heating. To improve heating quality and efficiency, large-sized bars (with diameters ≥100mm) are often heated in a medium-frequency induction heating furnace. This involves pushing the cold bar into the furnace for heating using a pusher. The hot bar, heated to 840-860°C, is then pushed out of the furnace and conveyed to the ring benders via a feeder for bending.

[0003] The existing anchor chain rod pushing device is driven by an oil cylinder or oil motor, which has a high manufacturing cost. The high temperature and harsh working environment causes the connecting seals and high-pressure hoses of the oil cylinder or oil motor to fail easily due to leakage, which reduces work efficiency, increases maintenance costs and poses a safety hazard of fire.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1 to 3 As shown, this embodiment includes a base frame 1, a drive mechanism 2, six support roller assemblies 3, a pusher mechanism 4, and a guide mechanism 5. The base frame 1 includes a rectangular frame 11 welded from section steel, and a top plate 12 welded and fixed to the rectangular frame 11. A bottom plate 13 is also provided on one end of the rectangular frame 11. The drive mechanism 2 is disposed on the bottom plate 13, and the six support roller assemblies 3 are supported side by side on one side of the top plate 12.

[0019] The driving mechanism 2 includes a horizontal pushing motor reducer combination 21 and a driven shaft seat 22 respectively fixed at both ends of the base plate 13. The driving pulley 211 of the horizontal pushing motor reducer combination 21 is connected to the driven pulley 222 on one end of the driven shaft 221 of the driven shaft seat 22 through a transmission belt 23. The driving sprocket 24 is fixed on the other end of the driven shaft 221. The driven sprocket 25 is fixed on one end of the support shaft 26. The support shaft 26 is supported on the support seat 53 at the other end of the top plate 12. The transmission chain 28 passes around the driving sprocket 25 and the driven sprocket 26 respectively. The two ends of the transmission chain 28 are respectively hinged to the chain joints 43 at both ends of the pushing mechanism 4.

[0020] The support roller assembly 3 includes a support roller 31 and a pair of bearing blocks 32. The support roller 31 is shaped like a frustum with two connected small ends in a V-shape. Extensions 311 at each end of the support roller 31 are supported in the bearing blocks 32, which are fixed to one side of the top plate 12. The bar 100 to be heated is supported on the V-shaped generatrix of the support roller 31.

[0021] like Figure 2 As shown, the push mechanism 4 includes a slide 41 and a push rod 42, and the two ends of the transmission chain 28 are respectively hinged to the chain joints 43 fixed at the two ends of the slide 41. Figure 3 As shown, the slide 41 is in an inverted L-shape, one end of the inverted L-shaped horizontal upper plate 411 is threadedly connected to one end of the push rod 42, one end of the chain joint 43 is respectively fixed to the middle part of the two ends of the horizontal upper plate 411 of the slide 41, and the inner side of the lower end of the vertical stand 412 of the slide 41 is supported on the top plate 12 by two roller bearings 44 arranged at intervals, so that the movement of the slide 41 is smoother. Figure 2The left end of the middle push rod 42 is fixed to the lower corner of the right end of the slide 41. The right end of the push rod 42 is fixedly connected to the left end of the anti-magnetic stainless steel push head 421 to prevent the pushed bar 100 from being magnetized. The axis of the push rod 41 matches the axis of the bar 100 to be heated supported by the six spaced support roller assemblies 3. The anti-magnetic stainless steel push head 421 pushes the bar 100 to be heated supported by the six support roller assemblies 3 into the corresponding medium frequency induction heating furnace for induction heating.

One end of the guide rod 51 is fixed on the other corner of one end of the slide 41. The middle part of the guide rod 51 passes through the guide sleeve 52. The guide sleeve 52 is fixed in the guide sleeve seat 413 at the intersection of the horizontal upper plate 411 and the vertical upright plate 412 of the slide 41. The guide mechanism 5 provides precise guidance for the movement of the push rod 42, ensuring that the heated bar 100 enters the medium frequency induction heating furnace smoothly.

[0023] When the utility model is working, the push motor reducer combination 21 is started by the PLC controller, and the push rod 42 on the right end of the slide 22 is driven through the transmission route of the driving pulley 211-driven pulley 222-driving sprocket 24-driven sprocket 25 to push the bar 100 into the medium frequency induction heating furnace for heating.

[0024] The push rod 42 of the present invention adopts an intermittent operation mode, which significantly reduces energy consumption and improves work efficiency.

[0025] In addition to the above embodiments, the present invention may also have other implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present invention.
