Description

Technical Field

[0001] The present application relates to the technical field of titanium rod rolling processing, and in particular to an auxiliary lifting device for continuous rolling processing of titanium rods. Background Art

[0002] Titanium rods are metal rods made of titanium and titanium alloys. They are widely used in aviation, medical, chemical and other fields due to their high strength, low density, good corrosion resistance and biocompatibility. The manufacturing process of titanium rods includes smelting, forging, heat treatment, and machining. Machining usually refers to the rolling process. The large-diameter titanium rod blanks after smelting are rolled through multiple stages to form small-diameter titanium rods with smaller outer diameters.

[0003] At present, titanium bars are continuously rolled using a multi-roll rolling mill, the structure of which is as shown in the attached manual. Figure 1 As shown, the multi-roller rolling mill has rolling holes which are jointly formed by upper and lower rolling rollers and arranged horizontally and vertically, and the diameter of the rolling holes gradually decreases along the horizontal direction. The rolling process of the titanium rod is as follows: first, the titanium rod blank with a larger outer diameter is heated in a heating furnace to a rolling temperature, and then the end of the heated titanium rod blank is taken out and passed through the rolling hole of the corresponding diameter. The rolling rollers are driven by a motor and a reducer (the rotation directions of the upper and lower adjacent rolling rollers are opposite, and the rotation direction is adjusted by a gear set). The titanium rod passes through the rolling hole and is squeezed by the external force of the upper and lower rolling rollers, thereby realizing a one-time diameter reducing rolling operation. After the titanium rod passes through the current rolling hole, its end is continuously passed through the rolling hole of the corresponding diameter size again to realize a secondary diameter reducing rolling operation, such as Figure 2 As shown, the diameters of ae and e decrease in sequence, such as Figure 3 The outer diameter change process of the titanium rod rolling is shown in the figure), thereby continuously realizing the step-by-step diameter reduction rolling operation of the titanium rod. This continuous rolling operation mode can greatly improve the efficiency of titanium rod rolling, shorten the rolling time, and ensure that the required rolling operation is completed before the titanium rod has a large temperature drop. It can effectively save the energy consumption caused by the frequent heating of the titanium rod, while improving the rolling efficiency of the titanium rod and reducing the processing cost.

[0004] The above rolling process should be able to achieve continuous rolling, so that the structure of the rolling mill is compact. For example, the rolling holes are horizontally and longitudinally distributed, and the reciprocating rolling operation needs to be carried out in the above-mentioned ae-threading method. Therefore, during rolling, the titanium rod needs to be continuously lifted and lowered to correspond to the corresponding rolling holes. In order to achieve flexible and fast continuous rolling, that is, the correspondence between the titanium rod and the rolling hole, the correspondence with the current rolling hole is currently achieved by manually lifting the end of the titanium rod. However, the titanium rod is heated at high temperature during the rolling process, and the manual lifting operation will always be in a high-temperature burning environment. In the process of driving the end of the titanium rod to correspond to the rolling hole, there is also a great risk of being scalded, which is not conducive to safe production. If the titanium rod is hoisted, the flexibility will be reduced, and the rolling operation cannot be completed during the temperature drop of the titanium rod. It needs to be reheated again, which increases the rolling cost and operation cycle. Summary of the invention

[0005] In response to the above-mentioned problems, the present application aims to provide an auxiliary lifting device for the continuous rolling processing of titanium rods, which can solve the current safety hazards caused by the need to manually align the titanium rods with the rolling holes, and at the same time solve the safety hazards of manual adjustment, while also realizing the guidance of the titanium rods and the rolling holes. Compared with manual alignment of the rolling holes, it can further improve the operational efficiency of continuous rolling.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: an auxiliary lifting device for continuous rolling processing of titanium bars, wherein a multi-roll rolling mill is used for continuous rolling of titanium bars, and the multi-roll rolling mill has rolling holes composed of upper and lower rolling rollers and arranged horizontally, transversely and vertically, and the hole diameter of the rolling hole gradually decreases along the horizontal direction, and it is characterized in that: the auxiliary lifting device is arranged on the outside of the rolling roller, and the auxiliary lifting device includes an auxiliary guide mechanism which can be adjusted laterally and vertically and corresponds to the axial direction of the rolling hole.

[0007] Preferably, the auxiliary lifting device comprises a frame-type bracket symmetrically arranged on both sides of the rolling roller and having a horizontal support rod, and the auxiliary guide mechanism is a guide roller slidably and rotatably sleeved on the horizontal support rod.

[0008] Preferably, the frame-type support includes a cylinder support rod that drives the horizontal support rod to rise and fall vertically and makes the guide roller correspond to the rolling holes on the upper and lower sides.

[0009] Preferably, a guide cylinder with a conical structure is arranged on the outside of each rolling hole.

[0010] The beneficial effect of the present application is that the auxiliary lifting device is arranged on the outside of the rolling roller, that is, the titanium rod is supported before and after the titanium rod is penetrated into the rolling hole, thereby solving the safety hazard that currently exists when the titanium rod needs to be manually aligned with the rolling hole. The auxiliary guiding mechanism is arranged, which can be adjusted horizontally and vertically to correspond to different rolling holes, that is, the titanium rod is driven to adjust and correspond to the rolling hole of the corresponding inner diameter, so that under the support of the lifting device and the auxiliary guiding mechanism driving the titanium rod and the rolling hole to guide, the safety hazard of manual adjustment is solved, and the guidance of the titanium rod and the rolling hole is also realized, which can further improve the operating efficiency of continuous rolling compared with manual alignment of the rolling hole.

[0021] 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.

[0022] See attached Figures 1 to 9 An auxiliary lifting device for continuous rolling of titanium bars is shown, Figure 1-5 As shown, the titanium rod is continuously rolled using a multi-roll rolling mill 1, which has rolling holes 1a composed of upper and lower rolling rollers 11 and arranged horizontally and vertically, and the hole diameter of the rolling hole 1a gradually decreases along the horizontal direction. The rolling process of the titanium rod is as described in the above background technology.

[0023] In order to solve the risk of burns caused by manual lifting of titanium bars in the current titanium bar rolling process, as well as the problem of increased rolling costs and operation cycles due to the use of hoisting, the present application is provided with an auxiliary lifting device, which is arranged on the outside of the rolling roller 11, that is, the titanium bar is supported before and after the titanium bar passes through the rolling hole 1a, thereby solving the current safety hazard of manually aligning the titanium bar with the rolling hole 1a.

[0024] Specifically, Figure 6-7 As shown, the auxiliary lifting device includes an auxiliary guiding mechanism which can be adjusted laterally and vertically and corresponds to the rolling hole 1a in the axial direction. The auxiliary guiding mechanism can be adjusted laterally and vertically to correspond to different rolling holes 1a, that is, the titanium rod is driven to adjust and correspond to the rolling hole 1a of the corresponding inner diameter. Therefore, under the support of the lifting device and the guiding effect of the auxiliary guiding mechanism driving the titanium rod and the rolling hole 1a, the safety hazard of manual adjustment is solved, and the guidance of the titanium rod and the rolling hole 1a is also achieved. Compared with manual alignment of the rolling hole 1a, the operating efficiency of continuous rolling can be further improved.

[0025] Specifically, Figure 6-7 As shown in FIG. 1 , the auxiliary lifting device comprises a frame-shaped bracket 2 symmetrically arranged on both sides of the rolling roller 11 and having a horizontal support rod 21, and the auxiliary guide mechanism is a guide roller 3 slidably and rotatably sleeved on the horizontal support rod 21. The horizontal support rod 21 serves as the rotation axis of the guide roller 3, and the guide roller 3 can slide horizontally on the horizontal support rod 21. The use process is as follows Figure 6 As shown, the end of the titanium rod is first placed and supported on the guide roller 3, and then the guide roller 3 is driven to slide on the horizontal support rod 21. After the titanium rod corresponds to the rolling hole 1a, the guide roller 3 is driven to rotate (preferably, a driving handle is extended on the side wall of the guide roller 3, not shown in the figure), and the end of the titanium rod is transported to the rolling hole 1a. Through the active drive of the rolling roller 11, the titanium rod passes through the rolling hole 1a and a single rolling operation is achieved.

[0026] After passing through the rolling hole 1a to the other side of the rolling roller 11, the position of the guide roller 3 on this side on the horizontal support rod 21 is pre-adjusted so that the rear end of the titanium rod can be supported on the guide roller 3 on this side. Then the guide roller 3 is driven to slide on the horizontal support rod 21 and correspond to the rolling hole 1a of the corresponding aperture. The above operation method is used again to drive the guide roller 3 to rotate, and the end of the titanium rod is transported to the rolling hole 1a, and is driven by the rolling roller 11 for rolling. Such reciprocating operation can realize continuous rolling of the titanium rod, thereby solving the current problem of manual lifting and easy burns caused by contact with the titanium rod.

[0027] Since the continuous rolling process of the rolling mill of the present application is staggered rolling up and down and left and right (as shown in the above ae rolling route), the titanium rod needs to be moved not only horizontally but also vertically lifted. Therefore, on the basis of the horizontal movement achieved by the horizontal support rod 21, in order to achieve vertical lifting, as shown in the above ae rolling route, the titanium rod needs to be moved horizontally and vertically. Figure 6 As shown, the frame support 2 includes a cylinder support rod 22 that drives the horizontal support rod 21 to rise and fall vertically and makes the guide roller 3 correspond to the rolling holes 1a on the upper and lower sides. The cylinder support rod 22 is preferably controlled by a foot pedal to facilitate the operation and driving of the rolling personnel. The entire continuous rolling lifting process is as follows Figure 8 As shown: In the first state diagram of the figure, the cylinder support rod 22 on the left is lifted by the operator's foot, and the heated titanium rod is placed on the guide roller 3 by a forklift or hoisting method, and then the guide roller 3 is driven to rotate to transport the titanium rod to the rolling hole 1a; as shown in the second state diagram, before the titanium rod passes through, the cylinder support rod 22 is driven to lift to the corresponding height, and the position of the guide roller 3 is adjusted to receive the rolled titanium rod; after receiving, as shown in the third state diagram, the foot is operated to control the cylinder support rod 22 to move downward After being lowered, it corresponds to the rolling hole 1a on the lower side, driving the guide roller 3 to rotate and conveying the titanium rod to the rolling hole 1a; as shown in the fourth state diagram, the cylinder support rod 21 on this side is lowered in advance, waiting to receive the rolled titanium rod, and after receiving it, the titanium rod is driven to be lifted to the first state diagram. In this way, the titanium rod can be rolled continuously, and the current safety hazards of manual operation and the problem that it is difficult to correspond to the rolling hole 1a due to the weight of the titanium rod body can be solved. On the basis of safe rolling, the rolling efficiency of the titanium rod can be further improved.

[0028] In the above operation process, since the titanium rod is driven to correspond to the rolling hole 1a by the manual sliding guide roller 3, there will be an alignment deviation, resulting in a decrease in alignment efficiency. Therefore, in order to solve this problem, Fig. 9As shown, a conical guide cylinder 4 is provided on the outside of each rolling hole 1a, and its outer end opening is relatively large. When the sliding guide roller 3 and the titanium rod are roughly corresponding to the rolling hole 1a, the larger outer end of the guide cylinder 4 is convenient for the entry of the titanium rod, that is, the titanium rod is allowed to have a certain position deviation. After the end of the titanium rod enters the guide cylinder 4, as its inner diameter decreases, the titanium rod and the rolling hole 1a can be accurately corresponded, thereby improving the alignment efficiency of the titanium rod and the rolling hole 1a.

[0029] The principle of the present application is: the auxiliary lifting device of the present application is arranged on both sides of the rolling roller 11, and when operating: Figure 8 As shown: the cylinder support rod 22 on the left side of the first state diagram in the figure is lifted by the operator's foot, and the heated titanium rod is placed on the guide roller 3 by a forklift or hoisting method, and then the guide roller 3 is driven to rotate to transport the titanium rod to the rolling hole 1a; as shown in the second state diagram, before the titanium rod passes through, the cylinder support rod 22 is driven to lift to the corresponding height, and the position of the guide roller 3 is adjusted to receive the rolled titanium rod; after receiving, as shown in the third state diagram, the foot-operated control cylinder support rod 22 is lowered to correspond to the rolling hole 1a on the lower side, and the guide roller 3 is driven to rotate to transport the titanium rod to the rolling hole 1a; as shown in the fourth state diagram, the cylinder support rod 21 on this side is lowered in advance to wait for receiving the rolled titanium rod. After receiving, the titanium rod is driven to lift to the first state diagram. In this way, titanium rod rolling can be carried out continuously.

[0030] 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.
