Description

TECHNICAL FIELD

[0001] The present application relates to the field of narrow strip steel production, in particular to a serpentine oscillator. BACKGROUND

[0002] In the production process of narrow strip steel, the strip steel is continuously bent by a serpentine oscillator and then conveyed to a flat plate conveying chain for storage and coiling. During the bending process, the surface of the strip steel often rubs against the edge of the outer opening of the guide groove of the serpentine oscillator, resulting in serious scratches on the surface of the steel, affecting the quality of the product.

[0003] In order to solve this problem, a pair of roller shafts is usually rotatably connected at the outer opening of the guide groove of the serpentine oscillator (for example, the narrow strip steel surface scratch prevention device and serpentine oscillator disclosed in Patent No. CN216728971U), and the serpentine oscillator drives the pair of roller shafts to reciprocate to bend the strip steel. During the movement of the strip steel relative to the roller shafts, the roller shafts rotate, thereby reducing the wear of the strip steel.

[0004] However, when the width of the produced strip steel is inconsistent, the height of the strip steel passing between the pair of roller shafts is different, and the roller shafts cannot better adapt to strip steels of different sizes. That is, when the height of the strip steel passing between the pair of roller shafts is greater than the height of the roller shafts, the roller shafts cannot better bend the strip steel. CONTENT OF THE INVENTION

[0005] In order to facilitate the roller shafts to adapt to strip steels of different heights, the present application provides a serpentine oscillator.

[0006] The serpentine oscillator provided by the present application adopts the following technical solution:

[0007] A serpentine oscillator, comprising a pair of bending plates, the pair of bending plates gradually incline towards each other and form an outer opening of a guide groove, each of the bending plates is provided with an extension roller near the outer opening of the guide groove, the extension roller comprises a connecting roller one connected with the bottom end of the bending plate, a connecting roller two vertically slidably connected with the connecting roller one, the upper end of each of the bending plates is fixedly connected with a driving cylinder, and the piston rod of the driving cylinder is upwardly arranged and connected with the upper end of the connecting roller two.

[0008] By adopting the above technical solution, the strip steel passes between the pair of bending plates and separates from the pair of bending plates along the outer opening of the guide groove. During the movement of the pair of bending plates, the pair of extension rollers bend the strip steel. When the height of the strip steel is different, the driving cylinder on each bending plate is started, the piston rod of the driving cylinder drives the connecting roller two to move relative to the connecting roller one, the connecting roller two moves away from or approaches the connecting roller one, thereby adjusting the height of the extension roller, and facilitating the adaptation to strip steels of different heights.

[0009] Preferably, the piston rod of the driving cylinder is detachably connected with the connecting roller two, and the outer side of the connecting roller one and the connecting roller two is sleeved with a sleeve pipe.

[0010] By adopting the technical scheme, when the strip steel moves relative to the telescopic roller, the strip steel can drive the sleeve pipe of the telescopic roller to rotate, reducing the occurrence of strip steel abrasion.

[0011] Preferably, the outer side of the connecting roller one and the connecting roller two is sleeved with a plurality of sleeve pipes.

[0012] By adopting the technical scheme, the number of sleeve pipes on the outer side of the connecting roller one and the connecting roller two can be increased or reduced to adapt to the height of the telescopic roller, without the need to produce sleeve pipes of several length specifications.

[0013] Preferably, the piston rod of the driving cylinder is detachably connected with the connecting roller two, and the outer side of the connecting roller one and the connecting roller two is sleeved with a sleeve pipe.

[0014] By adopting the technical scheme, the telescopic roller can be adjusted in angle and distance by rotating the adjusting shaft, the adjusting shaft driving the connecting rod one to rotate, and the connecting rod one driving the telescopic roller and the connecting rod two to rotate.

[0015] Preferably, the upper end of the fixed plate is fixedly connected with a supporting block, the upper end of the supporting block is rotatably connected with a reduction shaft, the reduction shaft is coaxially fixedly connected with a gear one, the adjusting shaft is coaxially fixedly connected with a gear two, the diameter of the gear one is smaller than the diameter of the gear two, and the gear one is engaged with the gear two.

[0016] By adopting the technical scheme, the telescopic roller can be adjusted in angle and distance by rotating the adjusting shaft, the adjusting shaft driving the connecting rod one to rotate, and the connecting rod one driving the telescopic roller and the connecting rod two to rotate.

[0017] Preferably, the reduction shaft is fixedly connected with a cover block, the limiting member includes a limiting rod threadedly connected with the cover block, and the lower end of the limiting rod abuts against the upper surface of the supporting block.

[0018] By adopting the technical scheme, the telescopic roller can be adjusted in angle and distance by rotating the adjusting shaft, the adjusting shaft driving the connecting rod one to rotate, and the connecting rod one driving the telescopic roller and the connecting rod two to rotate.

[0019] Preferably, the upper surface of the connecting roller one is provided with a sliding groove, and the lower end of the connecting roller two is inserted into the sliding groove and is in sliding connection with the connecting roller one.

[0020] By adopting the above technical scheme, when the piston rod of the driving cylinder pushes the connecting roller two to move, the connecting roller two slides in the sliding groove, and the sliding groove provides a guiding effect for the movement of the connecting roller two.

[0021] Preferably, the lower end of the connecting roller two is fixedly connected with a limiting block, and the diameter of the upper end opening of the sliding groove is smaller than the diameter of the limiting block.

[0022] By adopting the above technical scheme, the limiting block limits the occurrence of the disconnection of the connecting roller two from the connecting roller one.

[0026] 3. Facilitating the adjustment of the angle of the telescopic roller piece, thereby adjusting the distance between the two telescopic roller pieces. BRIEF DESCRIPTION OF DRAWINGS

[0033] When the height of the strip steel is different, the piston rod of the driving cylinder 11 drives the connecting roller two 32 to move relative to the connecting roller one 31, and the connecting roller two 32 moves away from or close to the connecting roller one 31, so as to adjust the height of the expansion roller 3.

The diameter of the upper end opening of the sliding groove 311 is smaller than the diameter of the limiting block 321, so as to reduce the situation that the limiting block 321 is separated from the sliding groove 311, and thus the connecting roller two 32 is difficult to be separated from the connecting roller one 31.

[0035] Specifically, the lower end of the connecting roller two 32 is fixedly connected with the limiting block 321. The diameter of the upper end opening of the sliding groove 311 is smaller than the diameter of the limiting block 321, so as to limit the situation that the connecting roller two 32 is separated from the connecting roller one 31.

[0036] Referring to Figure 2 and Figure 3 the piston rod of the driving cylinder 11 is fastened with the connecting roller two 32 through screws, and a plurality of sleeves 4 are sleeved outside the connecting roller one and the connecting roller two 32, and the plurality of sleeves 4 are arranged along the length direction of the expansion roller 3.

By rotating the adjusting shaft 14, the adjusting shaft 14 drives the connecting rod one 13 and the telescopic roller piece 3 to rotate, so as to adjust the angle of the telescopic roller piece 3, and further adjust the distance between the two telescopic roller pieces 3.

[0042] The limiting rod 51 is rotated, the limiting rod 51 moves downward and abuts against the support block 6, at this time, the cover block 63 and the reduction shaft 61 are locked, and further the position of the telescopic roller piece 3 is locked. When it is needed to unlock the telescopic roller piece 3, the limiting rod 51 is reversely rotated until the limiting rod 51 is separated from the support block 6, and the bottom end of the limiting rod 51 is higher than the gear one 62. At this time, the cover block 63 is rotated, the cover block drives the reduction shaft 61 to rotate, the reduction shaft 61 drives the adjusting shaft 14 to rotate through the gear one 62 and the gear two 16, and further the telescopic roller piece 3 is slowly adjusted to rotate.
