Description

Technical Field

[0001] The present application relates to the technical field of straightening a bent titanium rod, and in particular to a titanium rod mechanical straightening and straightness detection device. Background Art

[0002] During the production and forming process of titanium rods, due to the influence of process, equipment errors, external forces, etc., there is usually a certain straightness error, that is, there is a bend on the titanium rod body. Therefore, in order to improve the quality of the finished titanium rods, it is usually necessary to test the straightness of the titanium rods and straighten the bent titanium rods.

[0003] At present, titanium rods are still made of metal, so hydraulic straightening is usually used. It is a technical method to straighten titanium rods using hydraulic principles. In this process, hydraulic equipment accurately straightens titanium rods by applying appropriate pressure and force. This method is usually used to process bent or deformed titanium rods to restore them to a predetermined straightness or shape. Hydraulic straightening equipment is usually carried out using a hydraulic press, and the structure is as follows: Figure 1 As shown, it includes a straightening platform and support blocks arranged at intervals thereon, and a hydraulic rod in contact with the titanium rod and applying a straightening external force is also provided on the middle top side of the symmetrical support blocks. When the titanium rod is straightened, the titanium rod is placed on the support blocks on both sides, and the bent portion to be straightened is vertically aligned with the hydraulic rod, and the bent portion is convex toward the hydraulic rod. Then the hydraulic rod is driven downward, and after contacting the titanium rod, the titanium rod is gradually deformed and restored to a straight state by the hydraulic driving force, so that the straightening operation of the bent titanium rod can be quickly performed.

[0004] At present, when the hydraulic straightening operation of titanium rod is performed, since the bottom end of the hydraulic rod has a certain width, after it is applied to the bent part of the titanium rod, the bent part of the titanium rod will move from the convex structure ( Figure 2 as shown) into a concave structure that fits tightly against the hydraulic rod ( Figure 3 As shown in FIG. 1 , the titanium rod with the concave structure in contact with the bottom end surface of the hydraulic rod is separated from the bottom end surface of the hydraulic rod due to its deformation into the concave structure ( Figure 3 The side corners of the hydraulic rod are in contact with the surface of the titanium rod ( Figure 3 As shown in b in the figure, when a large hydraulic force is applied, the corners of the hydraulic rod are very likely to cause scratches on the surface of the titanium rod (the titanium rod is in a state of deformation when it is subjected to hydraulic external force). Figure 3 At the same time, the bending degree of each titanium rod is different. At present, when performing hydraulic straightening operations manually, it is usually necessary to visually check whether the titanium rod is straightened after the hydraulic rod is straightened once (such as Fig.12 However, there are usually certain errors in manual visual inspection, which results in the linear accuracy of the titanium rod being unable to be further guaranteed. Summary of the invention

[0005] In response to the above-mentioned problems, the present application aims to provide a titanium rod mechanical straightening and straightness detection device, which can have only a single contact point before, during and after the titanium rod is straightened and deformed, thereby solving the problem of the titanium rod being detached from the bottom surface of the hydraulic rod after deformation and causing mechanical damage by contact with the side, thereby effectively ensuring the surface quality of the titanium rod during the hydraulic straightening process and eliminating the subsequent polishing operation.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a titanium rod mechanical straightening and straightness detection device, including a straightening platform and support blocks arranged at intervals thereon, and a hydraulic rod in the middle top side of the symmetrical support block that contacts the titanium rod and applies a straightening external force, characterized in that: a driving body having a single contact point with the titanium rod in the state of deformation during the straightening of the titanium rod is arranged at the bottom end of the hydraulic rod, and a detection mechanism for detecting the straightness of the titanium rod is arranged on the support block.

[0007] Preferably, the driving body is a driving column which is arranged at the bottom end of the hydraulic rod and is perpendicular to the axial direction of the titanium rod and has a circular structure.

[0008] Preferably, a limiting groove for limiting the radial displacement of the titanium rod is provided on the bottom surface of the driving column.

[0009] Preferably, the detection mechanism is a detection plate embedded in the symmetrical support block and flush with the surface of the support block.

[0010] The beneficial effect of the present application is that the mechanical straightening and straightness detection device is provided with a driving body that has a single contact point with the titanium rod when the titanium rod is in a straightening and deformation state. The driving body can have only a single contact point before, during and after the straightening and deformation of the titanium rod, thereby solving the problem of the titanium rod being separated from the bottom surface of the hydraulic rod after deformation and causing mechanical damage by contact with the side, thereby effectively ensuring the surface quality of the titanium rod during the hydraulic straightening process and eliminating the subsequent polishing operation.

[0011] The detection mechanism set up can carry out targeted inspections on the parts of the titanium rod that are bent and need to be straightened, solving the problem of large deviations caused by manual visual inspection from the end of the titanium rod, thereby improving the straightness detection accuracy and improving the detection efficiency.

[0025] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0026] See attached Figures 4 to 11 A titanium rod mechanical straightening and straightness detection device shown includes a straightening platform 1 and support blocks 2 arranged at intervals thereon, and a hydraulic rod 3 that contacts the titanium rod and applies a straightening external force is also provided on the middle top side of the symmetrical support blocks 2. The current straightening method for bent titanium rods is to place the titanium rod on the support blocks 2 on both sides, and to vertically correspond the bent portion to be straightened to the hydraulic rod 3, while making the bent portion bulge toward the direction of the hydraulic rod 3, and then drive the hydraulic rod 3 downward, and after contacting the titanium rod, the hydraulic driving force drives the titanium rod to gradually deform and return to a straight state, and then through manual visual inspection, the straightening operation of the bent titanium rod is realized.

[0027] In order to solve the problem of avoiding mechanical damage to the surface of the titanium rod due to deformation of the titanium rod when straightening is currently performed by hydraulic rod, the present application provides a driving body at the bottom end of the hydraulic rod 3 that has a single contact point with the titanium rod as the titanium rod is straightened and deformed. The driving body has only a single contact point before, during, and after the titanium rod is straightened and deformed, thereby solving the problem of mechanical damage caused by the titanium rod being separated from the bottom surface of the hydraulic rod after deformation and contacting the side, thereby effectively ensuring the surface quality of the titanium rod during the hydraulic straightening process and eliminating the subsequent polishing operation.

[0028] At the same time, during the straightening process of the titanium rod, an effective and accurate straightness detection can be performed, and a detection mechanism for detecting the straightness of the titanium rod is provided on the support block 2. The detection mechanism is provided on the support block, and can perform targeted detection on the part of the titanium rod that is bent and needs to be straightened, solving the problem that the current manual inspection from the end of the titanium rod has a large deviation (affected by the bending at other positions on the surface of the titanium rod), thereby improving the straightness detection accuracy and improving the detection efficiency.

[0029] Specifically, Figure 4-5 As shown, the driving body is a driving column 4 which is arranged at the bottom end of the hydraulic rod 3 and is perpendicular to the axial direction of the titanium rod and has a circular structure. During the straightening operation, the hydraulic rod 3 drives the driving column 4 to contact the surface of the curved part of the titanium rod, and drives the curved part to bend and deform downward. As shown in Figure A, in the process of the titanium rod being deformed from a convex structure to a concave structure by the hydraulic pressure, it always has a single (circular arc) contact point with the bottom surface of the driving column 4, thereby effectively solving the problem of damage caused by contact with the bottom corner of the hydraulic rod 3 after the titanium rod is deformed.

[0030] Since both the titanium rod and the driving column 4 are cylindrical structures, the titanium rod may deviate radially from the driving column 4 and separate from the driving column 4 under a large hydraulic external force. Figure 6 As shown in the figure), there will be safety risks. Therefore, to solve this problem, Figure 7 As shown, a limiting groove 4a for limiting the radial displacement of the titanium rod is provided on the bottom surface of the driving column 4. When hydraulic straightening is performed, the titanium rod is embedded in the limiting groove 4a of the driving column 4. When the hydraulic straightening external force is applied, the radial limiting effect on the titanium rod can be effectively achieved, thereby improving the effectiveness and safety of the titanium rod straightening. In order to avoid mechanical damage to the titanium rod in a deformed state caused by the side of the limiting groove 4a, it is preferred that the limiting groove 4a is set as a circular arc structural surface along the circumference of the driving column 4.

[0031] In order to realize the rapid detection of straightness during the straightening process of titanium rods, Figure 8-11 As shown in FIG. 1 , the detection mechanism is a detection plate 5 embedded in the symmetrical support block 2 and flush with the surface of the support block 2. After the titanium rod is hydraulically straightened once, the titanium rod is Fig.11The middle arrow moves to the detection plate 5. Since the detection plate 5 is a planar structure, the straightness alignment state of the titanium rod can be quickly known by observing the gap between the titanium rod and the detection plate 5. At the same time, it also solves the problem that the current manual visual inspection from the end is affected by the bending of other parts of the titanium rod, thereby effectively improving the straightness detection accuracy and detection efficiency.

[0032] The principle of the present application is: when performing hydraulic straightening, the titanium rod is placed on the stacked support blocks 2, and the bent part is made to correspond to the limiting groove 4a of the driving column 4, and the bent part of the titanium rod is made to bulge upward, and then the hydraulic rod 3 drives the driving column 4 to move downward, and the titanium rod is embedded in the limiting groove 4a of the driving column 4, and the hydraulic straightening external force is continued to be applied to make the titanium rod bend and deform. After the hydraulic external force is applied, the titanium rod is shifted to the detection plate 5. By observing the gap between the titanium rod and the detection plate 5, the straightness straightening state of the titanium rod can be quickly known, until there is no gap between the bent part of the titanium rod and the detection plate 5 (the gap can also be tested using the light of a flashlight), and the straightening operation of the titanium rod is completed.

[0033] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
