It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, the utility model provides a turkish head will be described. The Turkish head comprises a roll frame 1, wherein the roll frame 1 comprises a mounting disc 12 in an annular structure and a plurality of connecting arms 13 fixed on one end face of the mounting disc 12, the connecting arms 13 are provided with lightening holes 131, the connecting arms 13 are uniformly distributed around the axial lead of the mounting disc 12, and the Turkish head further comprises a reinforcing ring 2. The reinforcing ring 2 and the mounting disc 12 are coaxially arranged and located on one side, away from the mounting disc 12, of the connecting arms 13, and the reinforcing ring 2 is fixedly attached to all the connecting arms 13.

The utility model provides a its head of turkey, compared with the prior art, the welded tube is revised after 2 coaxial passes of beaded finish, because the axial lead equipartitions of a plurality of linking arms 13 around mounting disc 12, so each linking arm 13 all can hinder other linking arms 13 through beaded finish 2 and outwards open the deformation, consequently can avoid when the wall thickness of welded tube is thick, reaction force when revising the welded tube can lead to the linking arm 13 in its head of turkey outwards to open the problem of deformation.

In some embodiments, referring to fig. 1 and 2, the end of each lightening hole 131 far away from the mounting plate 12 is provided with a reinforcing block 3 in a sliding way, all the reinforcing blocks 3 are fixedly connected with a reinforcing ring 2, and the reinforcing ring 2 pulls the connecting arms 13 with the outward flaring deformation tendency through the reinforcing blocks 3.

In some embodiments, referring to fig. 1 and 2, the reinforcing block 3 is provided with a first threaded hole 31, the first threaded hole 31 is perpendicular to the sliding direction of the reinforcing block 3, each connecting arm 13 is provided with a fixing bolt 4, and the fixing bolt 4 is inserted into the corresponding first threaded hole 31 and is in threaded connection with the inserted first threaded hole 31, so as to limit the reinforcing block 3 from sliding out of the inserted connecting arm 13. The reinforcing ring 2 can be detachably and fixedly connected with the connecting arm 13 through the threaded connection of the first threaded hole 31 and the fixing bolt 4. When the roll stand 1 needs to be repaired or replaced with some parts, the reinforcement ring 2 can be detached from the connecting arm 13 in order to avoid the influence of the reinforcement ring 2.

In some embodiments, referring to fig. 3, 4 and 5, the turkey head further comprises a removal structure comprising a stop 51, a connector 52, and an ejection screw 53. The stoppers 51 are attached to end surfaces of the two connecting arms 13 away from the mounting plate 12 and avoid the sliding path of the reinforcing block 3. The connecting piece 52 is positioned on one side of the limiting piece 51 far away from the connecting arm 13, the connecting piece 52 is detachably connected with at least one reinforcing block 3, and the connecting piece 52 is provided with a second threaded hole coaxial with the mounting disc 12. The middle of the pushing screw 53 is inserted into the second threaded hole and is in threaded connection with the second threaded hole, and one end of the pushing screw 53 facing the limiting member 51 is used for abutting against the limiting member 51.

Before the operation of the turkey head, the connection of the connecting member 52 with the attached reinforcing block 3 is disconnected, thereby removing the entire demolition structure. When some parts need to be overhauled or replaced in the roll stand 1 and the reinforcing ring 2 needs to be removed, after all the fixing bolts 4 are removed, if an operator directly pulls the reinforcing ring 2 by hand to slide the reinforcing block 3 out of the connecting arm 13, it is difficult because the force applied to the reinforcing ring 2 by the operator is hardly parallel to the sliding direction of the reinforcing block 3.

After all the fixing bolts 4 are removed, the limiting members 51 are attached to the end faces, far away from the mounting plate 12, of the two connecting arms 13, then the connecting members 52 are arranged on the side, far away from the connecting arms 13, of the limiting members 51 and connected with at least one reinforcing block 3, and the connecting members 52 cannot rotate along with the ejector screws 53 under the limitation of the connected reinforcing blocks 3. Then, the pushing screw 53 is driven to rotate so as to move toward the direction of the limiting member 51, and after the pushing screw 53 abuts against the limiting member 51, the pushing screw 53 is continuously rotated so that the pushing screw 53 presses the limiting member 51, and the connecting member 52 moves away from the connecting arm 13.

Since the second threaded hole is coaxially arranged with the mounting plate 12, the pushing screw 53 is parallel to the rotation axis of the roll stand 1, i.e. the sliding direction of the reinforcing block 3, so that the connecting member 52 moves in a direction away from the connecting arm 13, and all the reinforcing blocks 3 can slide out of the connecting arm 13 through the connected reinforcing blocks 3 and the reinforcing ring 2.

Since the lightening holes 131 penetrate the connecting arm 13 along the rotation axis of the roll stand 1 in the prior art, the reinforcing block 3 slides along the rotation axis of the roll stand 1.

In some embodiments, referring to fig. 5, 7 and 8, the detachment structure further includes two sliding shafts 54. The two sliding shafts 54 are both fixedly connected with the limiting piece 51, the sliding shafts 54 are parallel to the axial line of the mounting plate 12, and the two sliding shafts 54 are respectively slidably arranged in the two connecting arms 13 attached to the limiting piece 51. The two sliding shafts 54 can limit the stopper 51 from rotating and falling off with the ejector screw 53. When it is desired to remove the demolition structure, the two sliding shafts 54 are slid out of the penetrated connecting arm 13.

In some embodiments, to enable the removable connection of the connector 52 to at least one reinforcing block 3. Referring to fig. 5 and 6, a connecting screw 6 is fixedly arranged on each of the surfaces of the two reinforcing blocks 3 far away from the mounting disc 12, the connecting screw 6 is parallel to the axial line of the mounting disc 12, and the dismounting structure further comprises two connecting pipes 55. The two connecting pipes 55 are respectively sleeved on the two connecting screw rods 6, the connecting pipe 55 is provided with an internal thread in threaded connection with the sleeved connecting screw rods 6, the connecting pipe 55 penetrates through the connecting piece 52 in a sliding manner, the outer side wall of the connecting pipe 55 is provided with a limiting portion 551 protruding outwards, and the limiting portion 551 is used for being attached to the surface, away from the limiting piece 51, of the connecting piece 52. When the connecting piece 52 moves away from the connecting arm 13, the two reinforcing blocks 3 provided with the connecting screw 6 are pulled by the two limiting parts 551 to slide towards the outside of the connecting arm 13. The connecting pipe 55 is driven to rotate, so that the connecting pipe 55 is screwed to the corresponding connecting screw 6 or is detached from the connected connecting screw 6.

In some embodiments, referring to fig. 6, the position-limiting portion 551 has a hexagonal prism shape, so that the connection tube 55 can be driven to rotate by a tool such as a wrench.

In some embodiments, referring to fig. 3, the detachment structure further includes a drive shaft 56. The driving shaft 56 is perpendicular to the pushing screw 53 and is fixedly connected with one end of the pushing screw 53 far away from the limiting member 51. The driving shaft 56 can drive the pushing screw 53 to rotate in a labor-saving way.

In reality, the resistance of the reinforcing block 3 when sliding out of the penetrated connecting arm 13 may be relatively large due to rust or the like.

In some embodiments, the material of the reinforcement ring 2 is steel in order to provide the reinforcement ring 2 with high strength.

Based on the same inventive concept, the embodiment of the application also provides a welded pipe production line which comprises the Turkish head, and the problem that when the wall thickness of the welded pipe is thick, the connecting arm 13 in the Turkish head is expanded and deformed outwards due to the reaction force generated when the welded pipe is corrected can be solved.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
