TECHNICAL FIELD

[0001] The utility model relates to straightening machine technical field, especially relate to the round steel straightening machine for producing transformer corrugated oil tank. BACKGROUND

[0002] The transformer corrugated oil tank is a full-sealing structure oil tank, and its main feature is that the corrugated plate wall has heat dissipation and expansion and contraction functions. The corrugated plate wall automatically expands and contracts with the change of ambient temperature and load, so as to ensure that the transformer oil is completely isolated from air, and the transformer does not need to be maintained during the service life. When the transformer corrugated oil tank is produced, the material of the transformer corrugated oil tank needs to be straightened at the round steel straightening machine. The round steel straightening machine is a device for straightening round steel by using straightening pressure wheels, and is mainly used for improving the flatness of round steel.

[0003] At present, when the round steel material for the transformer corrugated oil tank is sent to the round steel straightening machine for straightening, the round steel is usually manually fed into the straightening wheel groove of the pressure wheel along the feed port of the straightening machine by workers. The manual feeding operation of workers is laborious, and multiple round steel straightening machines often need multiple workers to manually feed. The feeding efficiency of workers is also easily affected by human fatigue, so that the round steel straightening machine cannot meet the high-efficiency straightening demand of the raw material of the transformer corrugated oil tank. Therefore, we propose the round steel straightening machine for producing the transformer corrugated oil tank. UTILITY MODEL CONTENTS

The tail column of the push column 8 is welded to the surface of the feeding plate 9. A connecting disc 10 is bolted to the other side of the feeding plate 9 away from the push column 8. The disc of the connecting disc 10 is welded to the telescopic rod head of the electric push rod 11. A tail plate 12 is welded to the surface of the seat of the electric push rod 11. The tail plate 12 is bolted to the surface of the bracket 13. The base rod of the bracket 13 is welded to the surface of the U-shaped pallet 5 via the base plate 14.

[0025] The base rod of the bracket 13 is welded to the surface of the base plate 14, and the base plate 14 is welded to the surface of the vertical plate body on the other side of the U-shaped support plate 5 away from the L-shaped connecting plate 4.

[0026] By adopting the above technical solution, the base rod of the bracket 13 obtains stable support after being welded to the surface of the substrate 14, and then the substrate 14 can be welded together at the U-shaped support plate 5.

[0027] Among them, a baffle 16 is welded at the symmetrical frame opening of the U-shaped material frame 7 above the rubber disc 15;

[0028] By adopting the above technical solution, the welded baffle 16 at the opening of the U-shaped material frame 7 can prevent the round steel from falling out of the U-shaped material frame 7 above the rubber disc 15.

[0029] The arc-shaped groove of the receiving seat 6 is fitted with the arc-shaped bottom of the U-shaped material frame 7, and the receiving seat 6 is welded to the arc-shaped bottom of the U-shaped material frame 7.

[0030] By adopting the above technical solution, the receiving seat 6 uses an arc-shaped seat groove to receive the arc-shaped bottom of the U-shaped material frame 7 for welding.

[0031] The diameter of the pusher 8 is the same as the width of the cavity of the U-shaped material frame 7, and the opening of the U-shaped material frame 7 faces the inlet hole of the feed rack 2.

[0032] By adopting the above technical solution, the pusher 8 can enter the U-shaped material frame 7 to feed the round steel used for producing transformer corrugated oil tanks into the pressure rollers of the straightening machine body 1 through the feeding hole of the feeding frame 2 for straightening.

[0033] Among them, two sets of L-shaped connecting plates 4 are symmetrically welded on the frame surface of U-shaped support plate 5, and the vertical plate of L-shaped connecting plate 4 is locked to the machine box of straightening machine body 1 by bolts.

Then, the surface of the bracket plate 13 is fixed by bolts to the tail plate 12 of the electric push rod 11. Then, the connecting plate 10 at the telescopic rod head of the electric push rod 11 is locked with the feeding plate 9 by bolts. Then, the round steel for producing corrugated transformer tanks can be placed in the U-shaped material frame 7 and stacked. Then, the electric push rod 11 can be connected to an external controller for control. The extension of the telescopic rod allows the feeding plate 9 and the push column 8 to enter the U-shaped material frame 7 via the extension rod of the electric push rod 11. The push column 8 then pushes the bottom layer of round steel inside the U-shaped material frame 7 with the rubber disc 15, so that the round steel is fed into the pressure rollers of the straightening machine body 1 through the feeding hole of the feeding frame 2 for straightening. When the round steel is straightened and pulled away from the U-shaped material frame 7, the electric push rod 11 can pull back the push column 8 to leave the U-shaped material frame 7, so that the stacked round steel falls on the bottom wall of the cavity of the U-shaped material frame 7. Then, the electric push rod 11, together with the push column 8, can perform the next round steel straightening and feeding. This cycle repeats, so that the round steel in the U-shaped material frame 7 can be pushed into the straightening machine body 1 one by one for straightening. Afterwards, the worker only needs to add round steel from the U-shaped material frame 7.
