Description

Technical Field

[0001] The utility model relates to the technical field of pipe straightening, in particular to a high-efficiency straightening device for a precision rolled pipe. Background Art

[0002] Finished rolled tube, also known as cold-rolled precision steel tube, is a production process of seamless steel tube. It has the advantages of high precision, good surface finish and excellent comprehensive performance. It is widely used in the manufacturing of transportation vehicles such as automobiles, motorcycles, electric vehicles, petrochemical industry, energy and power industry, and machinery manufacturing field.

[0003] The finished rolled tube will undergo multiple transmissions and transportations during the production and processing. However, during the production and processing or transmission and transportation process, the finished rolled tube will experience collisions and extrusions. Collisions and extrusions will cause the steel tube to bend and deform. The bending and deformation not only affect the appearance of the finished rolled tube, but also affect the use of the finished rolled tube. Therefore, it is necessary to straighten it. The existing finished rolled tube straightening usually adopts a method of clamping and fixing the two ends of the finished rolled tube, and then applying force to the bent part to straighten it. However, in the existing steel tube straightening method, if the steel tube has multiple bending deformations and the bending directions are inconsistent, it is necessary to clamp the steel tube multiple times to straighten the multiple bending parts of the steel tube one by one, which has cumbersome operations and low efficiency in steel tube straightening. For this reason, the present application proposes an efficient straightening device for finished rolled tubes. Utility Model Content

[0004] The purpose of the utility model is to provide an efficient straightening device for a finishing tube in view of the deficiencies in the prior art, which realizes the efficient straightening function of the finishing tube by rotating the finishing tube in coordination with the support arm and the translation of the straightening arm, thereby solving the problem of low straightening efficiency of the finishing tube.

[0010] Preferably, a guide slide bar is horizontally fixed between the pair of fixed plates, and the guide slide bar movably passes through the slide seat.

[0011] Preferably, a first hydraulic push rod is vertically fixed on the slide seat, and the support arm is horizontally fixed on the telescopic end of the first hydraulic push rod.

[0012] Preferably, a pair of blocks are provided on the facing sides of the supporting arm and the straightening arm, and a second driving mechanism for driving the pair of blocks to move towards each other is provided on the supporting arm and the straightening arm.

[0013] Preferably, the second driving mechanism includes a slide groove opened on the support arm and the straightening arm, a bidirectional screw rod rotatably installed in the slide groove, and a second motor installed at the end of the support arm and the straightening arm for driving the bidirectional screw rod to rotate, a pair of the blocks are slidably engaged with the slide groove, and a pair of the blocks are symmetrically threadedly engaged with the bidirectional screw rod.

[0014] The beneficial effects of the utility model are:

[0016] 2) After the rotary clamping mechanism clamps one end of the finishing tube, the utility model starts the third motor to drive the rotary chuck to rotate, thereby driving the finishing tube to rotate. Therefore, on the basis of the rotation of the finishing tube and the translation of the support arm and the straightening arm, the finishing tube is straightened. Since the finishing tube is in a rotating state, the finishing tube is supported and pressed by the continuous translation of the support arm and the straightening arm, thereby achieving efficient straightening of the finishing tube.

At the same time, the first driving mechanism 6 is used to drive the slide 3 to drive the support arm 4 and the downward pressure straightening mechanism 5 to translate along the length direction of the finishing tube. On the basis of the rotation of the finishing tube and the translation of the support arm 4 and the downward pressure straightening mechanism 5, the downward pressure straightening mechanism 5 is used to perform downward pressure straightening treatment on the finishing tube. During the straightening treatment of the finishing tube, since the finishing tube is in a rotating state, efficient straightening of the finishing tube can be achieved.

[0029] As a preferred implementation scheme of this embodiment, the downward straightening mechanism 5 includes a fixed frame 11 fixed on the slide 3, a second hydraulic push rod 13 vertically fixed on the top wall of the fixed frame 11, and a straightening arm 14 fixedly installed at the telescopic end of the second hydraulic push rod 13.

[0030] As a preferred implementation manner of this embodiment, the rotating clamping mechanism 2 includes a fixed arm 20 fixed at one end of the top of the processing table 1, a rotating chuck 21 rotatably mounted on the fixed arm 20 facing the processing table 1, and a third motor 22 mounted on the third motor 22 for driving the rotating chuck 21 to rotate. The rotating chuck 21 is used to clamp and fix one end of the fine rolled tube. Starting the third motor 22 drives the rotating chuck 21 to rotate, thereby driving the fine rolled tube to rotate.

[0031] As a preferred implementation mode of this embodiment, the first driving mechanism 6 includes a pair of fixed plates 7 fixed on the upper surface of the processing table 1 and a one-way screw 8 horizontally rotatably installed between the pair of fixed plates 7. The one-way screw 8 threadedly penetrates the slide 3. A first motor 10 for driving the one-way screw 8 to rotate is installed on one of the fixed plates 7. When the first motor 10 is started to drive the one-way screw 8 to rotate, the slide 3 can be driven to drive the support arm 4 and the straightening arm 14 to translate along the length direction of the fine rolling tube. A guide slide bar 9 is horizontally fixed between the pair of fixed plates 7. The guide slide bar 9 movably penetrates the slide 3. The guide slide bar 9 is used to guide the translation of the slide 3.

[0032] In a further embodiment, a pair of blocks 15 are provided on the facing sides of the support arm 4 and the straightening arm 14, and a second driving mechanism 16 for driving the pair of blocks 15 to move toward each other is provided on the support arm 4 and the straightening arm 14.

[0033] Working steps

[0034] When in use, one end of the finishing tube is passed through the support arm 4 and the straightening arm 14 and clamped and fixed on the rotating clamping mechanism 2, and then the third motor 22 is started to drive the rotating chuck 21 to rotate, driving the finishing tube to rotate. At the same time, the first motor 10 is started to drive the one-way screw 8 to rotate, driving the slide 3 to drive the support arm 4 and the straightening arm 14 to translate along the length direction of the finishing tube. On the basis of the rotation of the finishing tube and the translation of the support arm 4 and the straightening arm 14, the first hydraulic push rod 12 and the second hydraulic push rod 13 are controlled to push the support arm 4 and the straightening arm 14 to move closer to each other and abut against the finishing tube, so as to achieve the straightening of the finishing tube. In the straightening process of the finishing tube, since the finishing tube is in a rotating state, the supporting arm 4 and the straightening arm 14 continuously translate to support and press the finishing tube, so as to achieve efficient straightening of the finishing tube. Furthermore, by starting the second motor 19 to drive the bidirectional screw 18 to rotate, a pair of blocks 15 on the support arm 4 and the straightening arm 14 can be driven to move closer to each other, which is used to limit the finishing tube on both sides between the support arm 4 and the straightening arm 14, assist in the straightening of the finishing tube, and further improve the straightening efficiency and straightening effect of the finishing tube.
