Description

Technical Field

[0001] The present invention relates to the technical field of titanium alloy processing, and particularly relates to a straightening device for titanium alloy materials. Background Art

[0002] Titanium alloy refers to an alloy metal made of titanium and other metals. Due to its excellent physical and chemical properties such as high strength, good corrosion resistance, and high heat resistance, titanium alloy metal materials are widely used in many technical fields such as aerospace, automotive ships, and medical equipment. In the production and use of titanium alloy materials, they are often made into plates, tubes, or other special-shaped materials, and various types of profiles can meet different production requirements.

[0003] Titanium alloy materials are generally made by processes such as rolling, extrusion, drawing, and casting. During the production process, titanium alloy materials often undergo deformation, bending, and distortion due to various reasons. The occurrence of these situations will cause the titanium alloy materials not to meet the design requirements. Therefore, after the titanium alloy materials are manufactured, they often need to be straightened by a straightening device to ensure the flatness of the materials.

[0004] However, the straightening devices in the prior art have relatively single functions and often can only process materials of one shape. For example, they can only process plates or tubes alone and are difficult to process materials of multiple shapes simultaneously. In addition, special equipment is often required for straightening some special-shaped parts. The straightening device is difficult to apply to various shapes of titanium alloy materials, and multiple different types of straightening devices are required for straightening, which not only increases the production cost but also reduces the production efficiency.

[0034] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely below. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts also belong to the scope of protection of the present invention.

[0035] As Figures 1-10 shown, the present invention provides a straightening device for a titanium alloy material, which includes a bottom plate 1. A lower straightening unit 2 is fixedly installed on the bottom plate 1, and an upper straightening unit 3 is arranged above the lower straightening unit 2. The lower straightening unit 2 includes a lower straightening box 21 fixedly installed on the bottom plate 1. A vertical partition 22 is arranged at the middle position of the lower straightening box 21 along the length direction. The vertical partition 22 divides the lower straightening box 21 into a first lower straightening part 23 and a second lower straightening part 24. A horizontal partition 25 is arranged in the first lower straightening part 23. The horizontal partition 25 divides the first lower straightening part 23 into a transmission cavity 26 above and a straightening cavity 27 below. A material feeding port 221 is also opened on the vertical partition 22. An inlet 211 is arranged on the end face of the lower straightening box 21 close to the first lower straightening part 23, and an outlet 212 is arranged on the end face close to the second lower straightening part 24. The upper straightening unit 3 includes an installation groove 31 fixedly installed on the top surface of the lower straightening box 21. Linear guide rails 32 are respectively installed on both sides of the installation groove 31 along the length direction. A plurality of gantry frames 33 are slidably connected to the linear guide rails 32. A straightening roll group 34 is installed on the installation groove 31 and the gantry frames 33.

[0036] The straightening device for the titanium alloy material mainly consists of three major structural parts, namely the bottom plate 1, the lower straightening unit 2 and the upper straightening unit 3. Among them, the bottom plate 1 is used for installing and bearing the entire device. The lower straightening unit 2 is used for straightening the tubular titanium alloy material. The upper straightening unit 3 is used for straightening the plate-shaped and other special-shaped titanium alloy materials.

[0037] The lower straightening unit 2 includes a lower straightening box 21 directly fixedly installed on the bottom plate 1. The lower straightening box 21 is divided into a first lower straightening part 23 and a second lower straightening part 24 by a vertical partition 22. Both straightening parts are used for straightening the tubular titanium alloy metal material. The first lower straightening part 23 is divided into a transmission cavity 26 for installing a transmission component above and a straightening cavity 27 for installing a straightening component to perform the straightening work of the pipe below by a horizontal partition 25.

[0038] The upper straightening unit 3 includes an installation groove 31. Linear guide rails 32 are installed on the installation groove 31. Gantry frames 33 are installed on the linear guide rails 32. A straightening roll group 34 for straightening the plate and other special shapes is installed on the gantry frames 33.

[0039] When the straightening device for titanium alloy materials is working and straightening pipes, the pipes are fed into the first lower straightening part 23 through the feeding port 211. After preliminary straightening, they are fed into the second lower straightening part 24 through the material conveying port 221 for secondary straightening. After the two straightening operations are completed, the pipes are sent out of the second lower straightening part 24 through the discharging port 212, and the straightening work is completed. When straightening plates or materials with other special shapes, the titanium alloy materials can be placed between the straightening roller sets 34 installed on the installation groove 31 and the gantry 33 for straightening.

[0040] The straightening device for titanium alloy materials provided by the present invention straightens pipes by setting the lower straightening unit 2, and straightens plates and materials with other special shapes by setting the upper straightening unit 3. The two work together to straighten various different types of titanium alloy materials simultaneously or in batches, improving production efficiency.

[0041] As Figure 4 shown, further, the straightening roller set 34 includes a plurality of horizontal straightening rollers 341, a plurality of vertical straightening rollers 342 and a plurality of support rollers 343. Among them, a plurality of horizontal straightening rollers 341 are installed on the installation groove 31 and the gantry 33 at the same time, and the vertical straightening rollers 342 and the support rollers 343 are alternately installed on the gantry 33.

[0042] The straightening roller set 34 is provided with horizontal straightening rollers 341, vertical straightening rollers 342 and support rollers 343. Among them, when a plurality of horizontal straightening rollers 341 are used alone, they are used to straighten sheet-shaped materials. When the horizontal straightening rollers 341 are used in cooperation with the vertical straightening rollers 342 and the support rollers 343, they can be used to straighten materials with special shapes, such as U-shaped titanium alloy materials, square titanium alloy materials, convex titanium alloy materials, etc.

[0043] As Figure 5 shown, further, the horizontal straightening roller 341 in the installation groove 31 is rotatably connected to the installation groove 31 and is driven by a first motor 3411. Both ends of the horizontal straightening roller 341 on the gantry 33 are installed on the gantry 33 through a connecting plate 3412. The connecting plate 3412 is slidably installed in the gantry 33 and is driven to lift by a second motor 3413 arranged at the top of the gantry 33.

[0044] A plurality of horizontal straightening rollers 341 are respectively installed on the installation groove 31 and the gantry 33. Among them, the horizontal straightening roller 341 installed in the installation groove 31 serves as the driving roller and is controlled to rotate by a first motor 3411 arranged on the outer side wall of the installation groove 31. The horizontal straightening roller 341 installed on the gantry 33 is a driven roller, which cooperates with the horizontal straightening roller 341 in the installation groove 31 to straighten the titanium alloy materials.

[0045] The horizontal straightening roller 341 installed on the gantry 33 can also cooperate with the connecting plate 3412 and the second motor 3413 to adjust the height, so that the distance between the installation groove 31 and the horizontal straightening roller 341 on the gantry 33 can meet the straightening requirements of plates with different thicknesses.

[0046] In addition, the gantry 33 can also slide on the installation groove 31 through the linear guide rail 32 to facilitate the maintenance of the device.

[0047] As Figure 6 shown, further, the installation structure of the vertical straightening roller 342 includes vertical fixed plates 3421 fixed on both sides of the gantry 33. A third motor 3422 is arranged on the outer side of each vertical fixed plate 3421. The output end of the third motor 3422 penetrates through the vertical fixed plate 3421 and is connected to the vertical moving plate 3423. Two mounting plates 3424 are arranged at the upper and lower ends of the vertical moving plate 3423 respectively. The vertical straightening roller 342 is rotatably connected between the two mounting plates 3424.

[0048] Two vertical straightening rollers 342 are installed on each gantry 33, and the installation structures of the two vertical straightening rollers 342 are the same. During use, each vertical straightening roller 342 is controlled to move by its corresponding third motor 3422: the output end of the third motor 3422 is connected to penetrate through the corresponding vertical fixed plate 3421 and the vertical moving plate 3423. The output end of the third motor 3422 pushes the vertical moving plate 3423, and the vertical moving plate 3423 drives the corresponding vertical straightening roller 342 to move. The two vertical straightening rollers 342 move towards each other to adjust the distance to adapt to materials of different thicknesses and sizes.

[0049] As Figure 7 shown, further, the installation structure of the support roller 343 includes vertical slide rails 3431 symmetrically arranged on both sides of the gantry 33. A fixed seat 3432 is fixed at each of the upper and lower ends of the vertical slide rail 3431. A lead screw 3433 is arranged between the two fixed seats 3432. A first movable seat 3434 is installed on the lead screw 3433, and the movable seat 3434 is also slidably connected to the vertical slide rail 3431. The lead screw 3433 is driven by a fourth motor 3435. A second movable seat 3436 is installed on the opposite surface of each of the two first movable seats 3434, and a fifth motor 3437 is installed on the opposite surface of each. The output end of the fifth motor 3437 penetrates through the first movable seat 3434 and is connected to the second movable seat 3436. A support roller 343 is rotatably installed on the opposite surface of each of the two second movable seats 3436.

[0050] Two support rollers 343 are also symmetrically arranged on each gantry 33. When the support rollers 343 are used to straighten the titanium alloy material: the fourth motor 3435 arranged at the top of each fixed seat 3432 controls the screw rod 3433 to rotate, and then drives the corresponding first movable seat 3434 to move up and down on the screw rod 3433, so as to control the height of the support roller 343 in the vertical direction. After the height of the support roller 343 is adjusted, the position of the second movable seat 3436 is controlled by the fifth motor 3437, and then the position of the support roller 343 in the horizontal direction is adjusted to adapt to the thickness of the material. After adjusting the position of the support roller 343 according to the size of the titanium alloy material, the material can be put in for straightening.

[0051] The horizontal straightening roller 341 is mainly used for flattening and straightening the plate, and can be used in conjunction with the vertical straightening roller 342 and the support roller 343 to straighten U-shaped materials, convex materials and square materials.

[0052] Furthermore, the first motor 3411 is a dual-output shaft rotary motor, the second motor 3413 , the third motor 3422 , and the fifth motor 3437 are all linear motors, and the fourth motor 3435 is a rotary motor.

[0053] like Figures 8-10 As shown, further, a plurality of transmission rods 251 and a plurality of mounting rods 252 are vertically penetrated on the horizontal partition 25, and the transmission rods 251 and the mounting rods 252 are arranged alternately. The transmission rod 251 is rotationally connected to the horizontal partition 25, and a horizontal bevel gear 261 is installed on the rod section located in the transmission cavity 26. A driving rod 253 is penetrated through the side wall of the transmission cavity 26, and a vertical bevel gear 262 meshing with the horizontal bevel gear 261 is installed on the rod section of the driving rod 253 located in the transmission cavity 26, and the outer end of the driving rod 253 is connected to the first motor 3411 through a belt 254. A horizontal straightening roller group 271 installed on the transmission rod 251 and the mounting rod 252 is also provided in the straightening cavity 27.

[0054] The horizontal straightening roller set 271 installed in the straightening chamber 27 is controlled and driven by the transmission assembly provided in the transmission chamber 26. When straightening the pipe, the output end of the first motor 3411 controls the driving rod 253 to rotate through the belt 254, and the driving rod 253 drives the vertical bevel gear 262 at its end to rotate, and the vertical bevel gear 262 drives the meshed horizontal bevel gear 261 to rotate, and the horizontal bevel gear 261 drives the transmission rod 251 to rotate, and finally drives the horizontal straightening roller set 271 in the straightening chamber 27 to operate.

[0055] like Figures 8-10As shown in the figure, further, the horizontal straightening roller set 271 includes a driving roller 272 fixedly installed on the transmission rod 251 and a driven roller 273 rotatably installed on the mounting rod 252. A rectangular adjustment slot 255 corresponding to the mounting rod 252 is further formed on the horizontal partition plate 25. A sliding plate 256 is slidably installed in the rectangular adjustment slot 255, and the mounting rod 252 is fixedly installed on the sliding plate 256. The sliding plate 256 is driven to displace by a sixth motor 213 arranged outside the lower straightening box 21.

[0056] The rotating transmission rod 251 drives the driving roller 272 to rotate, thereby driving the pipe being straightened forward. A straightening space for the pipe to pass through is formed between the driving roller 272 and the driven roller 273. The sliding plate 256 can be driven to slide in the rectangular adjustment slot 255 by the sixth motor 213, and further, the distance between the driving roller 272 and the driven roller 273 can be adjusted to adapt to pipes of different diameters.

[0057] As Figure 10 shown in the figure, further, a vertical straightening roller set 241 arranged orthogonally to the horizontal straightening roller set 271 is provided in the second lower straightening part 24. The vertical straightening roller set 241 is installed on a fixing plate 242, and the fixing plate 242 is fixedly connected to the bottom plate 1. The horizontal straightening roller set 271 and the vertical straightening roller set 241 have the same roller configuration structure.

[0058] The function of the vertical straightening roller set 241 provided in the second lower straightening part 24 is the same as that of the horizontal straightening roller set 271, which will not be elaborated here.

[0059] As Figure 1 shown in the figure, further, a tapered guide cylinder 217 is further installed outside the feed inlet 211. The guide cylinder 217 is horizontally arranged, and its axis coincides with the center line of the material passage of the lower straightening box 21.

[0060] By arranging the tapered guide cylinder 217 outside the feed inlet 211, when the pipe is put into the lower straightening box 21, the pipe can be quickly and accurately fed into the lower straightening box 21 from the feed inlet 211 through the tapered guide cylinder 217.

[0061] The following is the complete usage process and working principle of the straightening device for titanium alloy materials provided by the present invention:

[0062] As Figures 1-10As shown, when straightening the pipe, the pipe is fed into the first lower straightening section 23 through the feeding port 211. After preliminary straightening, it is fed into the second lower straightening section 24 through the material conveying port 221 for secondary straightening. After the two straightening operations are completed, the pipe is sent out of the second lower straightening section 24 through the discharging port 212 to complete the straightening work. When straightening the plate or other materials with special shapes, the titanium alloy material is placed between the straightening roller set 34 installed on the installation groove 31 and the gantry 33, and the position of the straightening roller set 34 is adjusted before straightening. The processes of straightening different types of titanium alloy materials are described below respectively.

[0063] The process of straightening the plate-shaped titanium alloy material is as follows:

[0064] As Figure 1 、 Figure 3 and Figure 5 shown, when straightening the plate-shaped titanium alloy material, the distance between the gantry 33 and the horizontal straightening roller 341 on the installation groove 31 is adjusted according to the thickness of the plate to be straightened. During the adjustment, the height of the connecting plate 3412 is controlled by the second motor 3413, and then the height of the horizontal straightening roller 341 on the gantry 33 is controlled. At the same time, the position of the gantry 33 needs to be adjusted through the linear guide 32 so that the positions of the horizontal straightening rollers on the gantry 33 and the installation groove 31 correspond. After the adjustment is completed, the first motor 3411 on the outer side wall of the installation groove 31 is started, and the first motor 3411 drives the horizontal straightening roller 341 located in the installation groove 31 to rotate. At this time, the plate is placed between the upper and lower horizontal straightening rollers 341, and straightening can be carried out.

[0065] The process of straightening the U-shaped titanium alloy material is as follows:

[0066] As Figure 1 、 Figure 4 、 Figure 7 shown, the U-shaped titanium alloy material has two additional vertical side plates compared with the plate-shaped titanium alloy material. When straightening, in addition to adjusting the horizontal straightening roller 341 according to the above-mentioned straightening work of the plate-shaped titanium alloy material, the position of the support roller 343 also needs to be adjusted according to the U-shaped titanium alloy material.

[0067] When adjusting, the distance between the opposite sides of the two supporting rollers 343 on the gantry 33 at even positions is the same as the outer width of the U-shaped titanium alloy material, and the distance between the opposite sides of the two supporting rollers 343 on the gantry 33 at odd positions is the same as the inner width of the U-shaped titanium alloy material. After adjustment, the U-shaped titanium alloy material can be placed for straightening. Under the action of multiple groups of supporting rollers 343, the straightening work of the U-shaped titanium alloy material can be completed. During the straightening process, the multiple supporting rollers 343 and the multiple horizontal straightening rollers 341 work together to straighten the whole U-shaped titanium alloy material. The two supporting rollers 343 on the gantry 33 at even positions straighten the part where the side wall of the U-shaped titanium alloy material bulges outwards, and the two supporting rollers 343 on the gantry 33 at odd positions straighten the part where the side wall of the U-shaped titanium alloy material sinks inwards.

[0068] It should be noted that the gantry 33 at even positions and the gantry 33 at odd positions mentioned above only refer to the gantry 33 on which the supporting rollers 343 are installed, and do not include the gantry 33 on which the vertical supporting rollers 342 are installed. The position of the supporting rollers 343 is jointly controlled by the fourth motor 3435 and the fifth motor 3437.

[0069] The process of straightening the square titanium alloy material is as follows:

[0070] As Figure 1 、 Figure 4 、 Figure 6 shown, when straightening the square titanium alloy material, first adjust the distance between the horizontal straightening rollers 341 according to the process of straightening the plate-shaped titanium alloy material. After the adjustment is completed, adjust the distance between the vertical straightening rollers 342 according to the width of the square titanium alloy material. When adjusting, the output end of the third motor 3422 pushes the vertical moving plate 3423, and the vertical moving plate 3423 drives the corresponding vertical straightening roller 342 to move. The two vertical straightening rollers 342 move towards each other, so as to adjust the distance to adapt to materials of different thicknesses. After the adjustment is completed, the material can be placed for straightening.

[0071] The process of straightening the convex titanium alloy material is as follows:

[0072] As Figure 1 、 Figure 4 、 Figure 7 shown, when straightening the convex titanium alloy material, first adjust the distance between the horizontal straightening rollers 343. The adjustment method is the same as the foregoing and will not be elaborated here. After the adjustment is completed, adjust the height of the supporting rollers 343 according to the thickness of the platform part of the convex titanium alloy material, and adjust the distance between the two supporting rollers 343 on the gantry 33 according to the width of the protrusion. After the adjustment is completed, the convex titanium alloy material can be placed for straightening.

[0073] The process of straightening the tubular titanium alloy material is as follows:
