Description

Technical Field

[0001] The utility model relates to the technical field of bar straightening, in particular to a new type of hydraulic cold straightening machine for cathode steel bars. Background Art

[0002] When producing cathode steel bars, usually due to uneven cooling during the cooling process, the cathode steel bars are bent or deformed. In the past, only through adjustment during the rolling process or intervention during the cooling process, the deformation amount was minimized as much as possible. For the rolled pieces that have already been deformed, they can only be treated as waste products, resulting in a reduction in the finished product yield and unsatisfactory economic indicators.

[0003] A straightening machine is a device for straightening metal profiles, bars, tubes, wires, etc. The straightening machine extrudes the bars and the like through straightening rolls to change their straightness. Generally, there are two rows of straightening rolls with different numbers. There are also two-roll straightening machines that rely on the angle change of the two rolls to straighten materials with different diameters. The main types include pressure straightening machines, balance roll straightening machines, shoe roll straightening machines, rotary reverse bending straightening machines, etc. The straightening rolls of the existing steel bar straightening machines are generally of a fixed design and cannot be used when straightening steel bars with different sizes and diameters, which has limitations. It is necessary to prepare multiple straightening devices suitable for different models of steel bars, which undoubtedly increases the investment cost of the enterprise and is difficult to meet the use requirements.

[0004] The existing straightening machines cannot straighten flat steel. In the past, only by adjusting the steel bars during the rolling process of the steel bars, the deformation amount was minimized as much as possible. For the steel bars that have already been deformed during the cooling process, they can only be treated as waste products, resulting in a large amount of waste of steel bars and a low finished product rate of cathode steel bars. The utility model provides a pressure straightening machine that presses the bent cathode steel bars against a reference baffle through the pressure provided by a hydraulic device, forcing the bent cathode steel bars to undergo local plastic deformation and improving the degree of bending, so as to meet the standard requirements and solve the problem of straightening the bent or deformed cathode steel bars. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a new type of hydraulic cold straightening machine for cathode steel bars to solve the problem of low finished product rate caused by bending and deformation of cathode steel bars due to uneven cooling.

[0006] To achieve the above purpose, the basic scheme provided by the utility model is: a new type of hydraulic cold straightening machine for cathode steel bars, including a cross beam, one end of the cross beam is fixedly connected with a straightening machine frame, a hydraulic jack is fixedly connected to the straightening machine frame, a hydraulic motor is electrically connected to the hydraulic jack, the other end of the cross beam is fixedly connected with a reference baffle, and the hydraulic jack and the reference baffle are arranged opposite to each other.

[0007] The working principle of the utility model is as follows: during use, first place the cathode steel bar to be straightened on the crossbeam, so that the cathode steel bar is located between the reference baffle and the straightening frame. Then, a worker adjusts the cathode steel bar to make the bent part of the cathode steel bar between the reference baffle and the hydraulic jack. Next, start the hydraulic jack through the hydraulic motor, and the hydraulic jack presses the cathode steel bar to be straightened against the reference baffle. Under the action of the hydraulic jack, the cathode steel bar is forced to produce plastic deformation, and the bent cathode steel bar can be straightened.

[0008] The beneficial effect of the utility model lies in that: the utility model realizes the improvement of the bending degree of the cathode steel bar by pressing the bent cathode steel bar against the reference baffle through the hydraulic jack, so that the cathode steel bar meets the standard requirements. This device can straighten the steel bar that has already undergone bending deformation, solving the problem that the cathode steel bar is bent and deformed due to uneven cooling during the cooling process, resulting in a low yield of the cathode steel bar.

[0009] Scheme 2, which is the preference of the basic scheme. Blocks are fixedly connected to both ends of the reference baffle, and the hydraulic jack can provide greater pressure to straighten the cathode steel bar with a larger bending degree.

[0010] Scheme 3, which is the preference of the basic scheme. Reinforcing ribs are fixedly connected to the crossbeam, and the other ends of the reinforcing ribs are fixedly connected to the reference baffle, increasing the stability of the reference baffle and making the reference baffle more firm.

[0011] Scheme 4, which is the preference of the basic scheme. A first pressing plate is fixedly connected to the hydraulic jack, increasing the contact surface between the hydraulic jack and the cathode steel bar and facilitating the straightening of the cathode steel bar.

[0012] Scheme 5, which is the preference of the basic scheme. A second pressing plate is fixedly connected to the first pressing plate, raising the first pressing plate so that it can adapt to cathode steel bars of different specifications.

[0013] Scheme 6, which is the preference of the basic scheme. A transport roller path is provided between the crossbeams. A bearing seat is provided on the transport roller path, and a ground roller is rotatably connected to the bearing seat. The rotatably connected ground roller facilitates the staff to adjust the position of the cathode steel bar. Description of the Drawings

The hydraulic jack 3 and the reference baffle 5 are arranged opposite to each other, and at both ends of the reference baffle 5 there are fixedly connected stop blocks 6.

[0019] The implementation mode of this embodiment is as follows: When it is necessary to straighten the deformed cathode steel bars, first use a crane to place the deformed cathode steel bars on the ground roller 12, so that the cathode steel bars are located between the reference baffle 5 and the straightening frame 2. Then, a worker moves the cathode steel bars on the ground roller 12 to make the cathode steel bars slide on the ground roller 12, and adjust the deformed part of the cathode steel bars between the hydraulic jack 3 and the reference baffle 4. Then, another worker starts the hydraulic motor 4. Under the action of the hydraulic motor 4, the first pressing plate 8 on the hydraulic jack 3 extends. Then, under the action of the hydraulic jack 3, the first pressing plate 8 presses the deformed cathode steel bars against the reference baffle 4.
