Description

Technical Field

[0001] The utility model relates to the technical field related to titanium alloy bar processing, in particular to a device for improving the bending of materials after the cold-drawn large coil is peeled and unloaded. Background Art

[0002] Titanium alloy bars have the advantages of high specific strength, excellent corrosion resistance, good biocompatibility, and good welding, hot and cold pressure processing and machining properties. They can be processed into various titanium profiles, titanium bars, titanium plates and titanium pipes. They are widely used in aviation, aerospace, ships, nuclear industry, petroleum, chemical industry, medical and other fields.

[0003] Titanium alloy bars will produce residual stress after cold plastic deformation. Even under zero pressure, a certain compressive stress will still remain. At this time, the titanium alloy bars need to be peeled and cut, but the residual stress inside the cold-drawn material causes the titanium alloy bars to deform. The titanium alloy bars are bent, causing difficulties in subsequent peeling and feeding, which seriously affects the production efficiency and stability of the production process.

[0024] The details are as follows;

[0025] See also Figure 1 , Figure 2 , the workbench, the curvature correction device 1, the feeding and pressing device 2, the peeling device 3, the material cutting device and the discharging and pressing device 7 are arranged on the workbench in this order along the material conveying direction, the curvature correction device 1 includes the support frame 16 and the double-wheel conveying mechanism and the first hydraulic device 11 installed on the support frame 16, the movable end of the first hydraulic device 11 is rotatably installed with the ejecting wheel 9, the ejecting wheel 9 is located in the middle position of the double-wheel conveying mechanism, and a gap is formed between the ejecting wheel 9 and the mechanism for the material to pass through;

[0026] It also includes the control system, which establishes communication with the first hydraulic device 11 and the two-wheel conveying mechanism, and is used to control the first hydraulic device 11 and the two-wheel conveying mechanism to perform actions in sequence.

[0027] The control system generally consists of a controlled object, a controller, an actuator, and a sensor. The sensor is responsible for measuring the state information of the first hydraulic device 11 and the two-wheel conveying mechanism, and transmits the information to the controller through the feedback channel. In the controller, the feedback signal measured by the sensor is compared with the given desired control signal, and the control output is obtained according to the selected control algorithm. The control output acts on the actuator to control the controlled object, so that the controlled object produces the desired control effect. The control system in this utility belongs to the prior art, and this utility will not be redundantly described.

[0028] In detail, in this embodiment, the device for improving the bending of materials after peeling and unloading of cold-drawn large coils as described in the utility model is adopted. When in use, the cold-drawn material is extended into the curvature correction device 1 in the opposite direction of the material curvature, and the control system sends a signal to the first hydraulic device 11, and the first hydraulic device 11 starts to work, so that the pushing wheel 9 pushes the material upward to correct the curvature of the material, so that the material after peeling is no longer bent, which is beneficial to the vertical correction of the material loading and the stability of the material cutting length.

[0029] See also Figure 1 , Figure 2 The double-wheel conveying mechanism includes two symmetrically arranged feed rotating wheels 10, and the feed rotating wheels 10 are rotatably mounted on the support frame 16. The feed rotating wheels 10 are driven to rotate by a first motor 8 fixedly mounted on the support frame 16, and the first motor 8 establishes communication with the control system.

[0030] Furthermore, after the first hydraulic device 11 finishes working, the control system sends a signal to the control panel of the first motor 8 to start the first motor 8. When the first motor 8 is working, it drives the output shaft to rotate. When the output shaft rotates, it drives one of the feed rotating wheels 10 to rotate. The two feed rotating wheels 10 are connected by a belt rotation to achieve the material transportation requirements.

[0033] After passing through the peeling device 3, the material is transported to the length sensor 5. The length to be cut is set in the control mechanism 4. When the length of the material passing through the length sensor 5 reaches the set length value, the control mechanism 4 sends a signal to the third hydraulic device fixedly installed on the workbench. The movable end of the third hydraulic device is connected to the cutter disc 6. When the third hydraulic device starts working, the cylinder rod of the third hydraulic device extends to drive the cutter disc 6 to cut the material, so as to realize the cutting and unloading requirements of the material.

[0038] It should be noted that the feeding and pressing device 2 has the same structure as the discharging and pressing device 7, and performs the work of conveying and pressing the materials.

[0039] To elaborate, the material after unloading is conveyed through the discharging and pressing device 7, wherein the second hydraulic device 12 drives the discharging and pressing wheel 13 to press the material, wherein the interval between the discharging and pressing wheel 13 and the discharging rotating wheel 14 is adjustable to meet the needs of conveying and pressing materials of different sizes, keep the material in a compacted state at all times, and avoid the material from jumping during transportation. Then, the second motor 15 is started to work, and the second motor 15 drives the output shaft to rotate. When the output shaft rotates, it drives one of the discharging rotating wheels 14 to rotate. The multiple discharging rotating wheels 14 are connected by belt rotation to realize the discharging and transmission of the material.
