Description

Technical Field

[0001] The utility model relates to the technical field of cold processing of titanium flat bars, in particular to a full-automatic tension control system for cold processing of titanium flat bars. Background Art

[0002] When processing titanium flat bars, cold drawing equipment is usually used to produce titanium flat bars. The production method is mainly through winch cold drawing and resistance cold drawing. Since the size of titanium flat bars is generally small, resistance cold drawing is usually used, that is, the raw material is pulled by a reel with strong force, so that the raw material passes through a resistance wheel group composed of multiple resistance wheels on the cold drawing equipment to produce tensile deformation to form a qualified titanium bar. However, the existing traction reel is mostly driven by an ordinary motor to drive the material through the cold drawing equipment. The motor speed is mostly in a constant state, and it is difficult to change the speed according to the tension of the titanium bar. When the tension of the titanium bar changes, the motor speed is constant, which will cause the traction reel to be too loose or too tight when pulling the titanium bar. If the traction force is too loose, the titanium bar will easily be twisted after passing through the cold drawing equipment. If the traction force is too tight, the titanium bar will be too thin or even broken after passing through the cold drawing equipment, affecting the qualified rate of the titanium bar, easily generating waste, causing waste of raw materials, and being relatively inconvenient.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 3In the embodiment of the utility model, a fully automatic tension control system for cold working of titanium flat bars includes a cold drawing device, an adjustment mechanism 400 is provided on one side of the cold drawing device, and a tension detector 300 is provided between the cold drawing device and the adjustment mechanism 400;

[0024] The adjustment mechanism 400 includes a box body 410 , and a driving motor 420 is fixedly connected inside the box body 410 . The motor shaft of the driving motor 420 is fixedly connected to a magnetic powder brake 430 . The output end of the magnetic powder brake 430 passes through one side of the box body 410 and is fixedly sleeved with a traction wheel 431 .

[0025] Specifically, the titanium bar 100 is a titanium flat bar produced by the cold drawing equipment. During production, the titanium bar 100 is pulled by the traction wheel 431 and continuously produced through the cold drawing equipment. By starting the drive motor 420, the traction wheel 431 rotates to reel in the titanium bar 100 and pulls the titanium bar 100 to move, so that the titanium bar 100 is stretched and deformed by the pulling force of the traction wheel 431 through the resistance wheel group on the cold drawing equipment. When the traction wheel 431 pulls the titanium bar 100, the tension detector 300 is close to the titanium bar 100. The tension of the titanium bar 100 can be detected by the tension detector 300, and the magnetic powder brake 430 is controlled to adjust the rotation of the traction wheel 431 according to the tension of the titanium bar 100, so as to automatically adjust the tension of the titanium bar 100, so that the tension on the titanium bar 100 is more uniform, and the breakage and scrapping caused by uneven force during stretching are reduced, thereby improving the production qualification rate, reducing the waste of materials, and saving the use of raw materials.

[0026] Embodiment 1

[0027] like Figure 1-3 As shown, in this embodiment, a guide wheel 110 is provided on one side of the traction wheel 431, the tension detector 300 is located between the guide wheel 110 and the traction wheel 431, and a guide frame 200 is provided on one side of the guide wheel 110, and the center of the guide frame 200 and the groove of the guide wheel 110 are located in the same vertical plane.

[0028] In this embodiment, the guide frame 200 and the guide wheel 110 can both be installed on the bracket, and the bracket is fixed to the ground. The guide frame 200 is close to the resistance wheel group on the cold drawing equipment. The titanium bar 100 will pass through the guide frame 200 after passing through the resistance wheel group. The titanium bar 100 is supported and limited by the guide frame 200 and the guide wheel 110, so that when the titanium bar 100 is pulled, it is not easy to separate from the tension detector 300 due to the limitation of the guide frame 200 and the guide wheel 110.

[0029] like Figure 1-3As shown, in this embodiment, an electric control box 440 is fixedly connected to one side of the box body 410, and a control device is arranged inside the electric control box 440, the control device is electrically connected to the tension detector 300 and the magnetic powder brake 430, the magnetic powder brake 430 is a double-extension shaft magnetic powder clutch, the control device is a programmable logic controller, the tension detector 300 is a through-shaft tension sensor, and the traction wheel 431 is located above the bottom surface of the box body 410.

[0030] In specific implementation, the programmable logic controller, i.e., PLC, can store instructions for executing operations such as logic operations, sequential control, timing, counting and arithmetic operations through the internal memory, and control various types of mechanical equipment or production processes through digital or analog input and output. It is a prior art. The drive motor 420 and the magnetic powder brake 430 can be controlled by the programmable logic controller in the electric control box 440. When the titanium bar 100 is relaxed or tightened, the tension detector 300 sends a signal to the programmable logic controller, so that the programmable logic controller automatically adjusts the torque of the magnetic powder brake 430 according to the program, so that the magnetic powder brake 430 adjusts the speed of the traction wheel 431 to restore the original tension of the titanium bar 100. The traction wheel 431 has a certain height from the ground, so that the titanium bar 100 wound thereon is not easy to contact the ground. The double-extension shaft magnetic powder clutch can steplessly adjust the speed of the traction wheel 431. The tension detector 300 can be installed on a bracket, and the bracket is fixed on the ground. The tension change of the titanium bar 100 can be detected by the through-axis tension sensor.

[0031] Embodiment 2

[0032] On the basis of the first embodiment, a buzzer is provided to warn personnel.

[0033] like Figure 1-3 As shown, in this embodiment, a buzzer is disposed inside the box body 410 .

[0034] During specific implementation, the buzzer is also connected to the programmable logic controller. When the titanium bar 100 shows obvious tension changes, the tension detector 300 can send a signal to the programmable logic controller. The programmable logic controller adjusts the magnetic powder brake 430, thereby adjusting the speed of the traction wheel 431. At the same time, the buzzer can alarm to remind personnel to check and manually check whether the tension of the titanium bar 100 is fully restored. If not, manual auxiliary adjustment can be performed.
