DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0019] Reference Figures 1 to 5The copper pipe rod straightening positioning assembly shown comprises a left moving frame 1 and a right moving frame 2 which are symmetrically arranged and have the same structure, both of which comprise a fixedly arranged base 3, a moving seat 4 in linear sliding fit is arranged on the base 3, two supporting roller seats 5 are arranged at intervals on the moving seat 4, two liftable supporting rollers 6 are arranged between the two supporting roller seats 5, and a pressing roller 7 which can be pressed downward to the direction of the rotating supporting roller 6 is arranged on one of the supporting roller seats 5.
[0020] The main innovation of the utility model lies in that the supporting roller 6 is movable. In work, the copper pipe or copper rod to be straightened is placed on the left moving frame 1, and then the copper pipe or copper rod is gradually transferred to the right moving frame 2 as it is straightened part by part, in the process, the left moving frame 1 and the right moving frame 2 adjust the supporting position according to the distance of the copper pipe or copper rod extending on both sides of the pressing head, so as to avoid the copper pipe or copper rod from being bent by gravity.
[0021] In the design, the movement of the supporting roller 6 can form dynamic support, so that different positions can be supported according to the specific situation of the copper pipe or copper rod, thereby adapting to the changes in the whole straightening process.
[0022] In the embodiment, in order to ensure that the movement of the moving seat 4 is accurate and stable, a linear rack 8 is arranged on the base 3. The linear rack 8 can make the movement of the moving seat 4 more accurate, so that the position and direction of the copper pipe or copper rod can be kept accurate during straightening. Meanwhile, a driving gear 9 and a first servo motor 10 which cooperate with the linear rack 8 are arranged on the moving seat 4, so that the movement of the moving seat 4 is accurate and fast, and the straightening quality is further improved.
[0023] In the embodiment, a supporting roller base 11 which slides up and down on the two supporting roller seats 5 is arranged between the two supporting roller seats 5, and the supporting roller 6 is rotatably arranged on the supporting roller base 11. In the design, the supporting roller base 11 is an important component for supporting and fixing the supporting roller 6, and the arrangement of the supporting roller base 11 can make the supporting roller 6 slide up and down during straightening, so that a larger straightening range can be provided and copper pipes or copper rods of various specifications can be adapted.
[0024] In the embodiment, a first hydraulic cylinder 16 is arranged below the supporting roller base 11, which is mainly used to drive the lifting movement of the supporting roller base 11. The design of the hydraulic cylinder can make the supporting roller base 11 be accurately controlled in the vertical direction, and the hydraulic cylinder is selected instead of a pneumatic cylinder, mainly because the load capacity of the hydraulic cylinder is stronger. The hydraulic cylinder can effectively resist various forces and pressures generated during straightening of the supporting roller 6, and ensure the safe operation of the supporting roller base 11.
[0025] In the embodiment, the end of the shaft of the two carrier rollers 6 is provided with a driven gear 12, the two driven gears 12 are provided with a transmission gear 13, the inside of the carrier roller base 11 is provided with a driving gear 14 matched with the transmission gear 13 and a second servo motor 15.
[0026] The carrier rollers 6 rotate synchronously left and right during the straightening process, which can drive the copper pipe and copper bar to rotate, provide more straightening angle and adapt to more complex straightening requirements.
[0027] In the embodiment, the carrier roller base 5 is provided with a swing arm 17 and a second hydraulic cylinder 18 for driving the swing arm 17 to rotate and press the two carrier rollers 6, and the pressing roller 7 is rotatably arranged at the end of the swing arm 17.
