Description

Technical Field

[0001] The present invention relates to the technical field of titanium ingot pressing forming, and particularly to a titanium ingot electrode forming system. Background Art

[0002] In recent years, with the rapid development of the aviation industry, the titanium alloy industry has developed rapidly, and the application and market prospect of the corresponding electrode forming pressing hydraulic press are also quite broad.

[0003] After the existing titanium ingot electrode bar products are formed at the end of the pressing process by the press, it is necessary to move the pressed and formed products from the position of the mold cavity to the conveying equipment to complete the processes of discharging, weighing, flipping, and stacking before the next product can be filled and stamped to ensure continuous production. At present, in the simple type of titanium ingot forming hydraulic press, each process such as handling and transferring between processes is realized by manual handling with a crowbar. Since the electrode block is heavy, manual stacking is not only difficult, with low work efficiency, but also has cumbersome processes and cannot be continuous. This not only increases the product cost and reduces the production efficiency, but also is not conducive to batch industrial production and the requirements of modern industrial management. In addition, on some advanced titanium ingot forming hydraulic presses, professional manipulators are used to achieve handling. This method improves the production efficiency of the products, but the equipment cost and maintenance cost are also greatly increased.

[0035] A hydraulic cylinder, also known as an oil cylinder, is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or oscillating motion). It has a simple structure and reliable operation. When used to achieve reciprocating motion, it can eliminate the need for a speed reduction device, and there is no transmission gap, resulting in smooth motion. At the same time, the oil cylinder has a higher power density than the conventional motor-reducer mechanical structure, so it is widely used in the hydraulic systems of various machines. However, in the specific application scenario of the titanium ingot forming automation production line, if a single oil cylinder is used in combination with a conveying roller table to meet the transfer between the processes of discharging, weighing, flipping, and palletizing after the titanium ingot is pressed and formed, due to its long stroke, it is necessary to increase the length of the cylinder barrel and piston to increase the sliding distance of the piston. However, this inevitably increases the installation space and cannot be used under the condition of a small installation space, resulting in poor flexibility in use. When the piston rod, which is a shaft or rod-like part, extends, it is in a cantilever state. The longer its length, the more likely it is to bend under the action of its own gravity, and it is not easy to repair after damage, which greatly affects the production efficiency. Moreover, in the application scenario of the titanium ingot pressing process transfer, if a single oil cylinder is used, its stroke must be increased. After the long-stroke piston rod extends completely, the end push head will inevitably droop, and its acting force axis will be inclined, resulting in crossing with the center of the titanium ingot being pushed, and then causing the pressed green titanium ingot to collide with the roller of the transmission line body, resulting in defects such as missing edges and corners of the product, affecting the product quality.

[0037] The present invention provides a titanium ingot electrode forming system, as Figures 1 to 5As shown in the figure, the titanium ingot electrode forming system includes: a press 1, an aggregate device 2, and a pusher device 3; the aggregate device 2 and the pusher device 3 are arranged at the front end of the press 1; the pusher device 3 includes a bracket 31 and a first pusher oil cylinder 32, the first pusher oil cylinder 32 includes a first piston rod 321, a cylinder block 322, and a second piston rod 323, the first end of the first piston rod 321 is fixedly connected to the bracket 31, the first end of the cylinder block 322 is sleeved on the second end of the first piston rod 321 and is slidably connected to the bracket 31, and the first end of the second piston rod 323 is sleeved on the second end of the cylinder block 322; the gap between the first piston rod 321 and the first end of the cylinder block 322 forms a first hydraulic cylinder 324, the gap between the second piston rod 323 and the second end of the cylinder block 322 forms a second hydraulic cylinder 325, and the gap between the first piston rod 321 and the second piston rod 323 and the cylinder block 322 form a third hydraulic cylinder 326; the aggregate device 2 includes a first platform 21 and a second platform 22, and the second piston rod 323 is used to push the titanium ingot arranged at the upper end of the first platform 21 to the upper end of the second platform 22.

[0038] In this embodiment, by arranging the first piston rod 321, the second piston rod 323, and the cylinder block 322, the problem that the end of the second piston rod 323 sags, resulting in the inclination of the acting force axis, is solved. While realizing a double-rod output of one cylinder, the cylinder block 322 itself can also slide relative to the bracket, thereby improving the rigidity of the output end of the second piston rod 323, improving the space utilization rate, reducing the labor cost, and further realizing the rapid and stable transfer of the titanium ingot.

[0039] According to some preferred embodiments of the present invention, the cross-sections of the first piston rod 321 and the second piston rod 323 are T-shaped, and both the first end and the second end of the first pusher oil cylinder 32 are hermetically connected to the piston rod.

[0040] According to some preferred embodiments of the present invention, when the third hydraulic cylinder 326 is filled with oil, the first piston rod 321 remains stationary, the cylinder block 322 moves forward. After the first piston rod 321 is completely exposed, the cylinder block 322 fixes the second piston rod 323 to move forward, dividing the overall stroke into two parts, breaking it into smaller parts, realizing a large stroke through the relay of short-stroke hydraulic cylinders, and each stroke has a reliable support, so that the second piston rod 323 still maintains sufficient rigidity after extending, ensuring the smoothness of pushing the material, solving the problem of the cantilever sag of the piston rod end of the long-stroke oil cylinder after extending, avoiding the collision and damage of the titanium ingot product with uneven pressing density of particulate materials caused by the non-parallel acting line, and improving the product quality.

[0041] According to some preferred embodiments of the present invention, when the first hydraulic cylinder 324 is filled with oil, the cylinder block 322 retracts; when the second hydraulic cylinder 325 is filled with oil, the second piston rod 323 retracts.

[0042] According to some preferred embodiments of the present invention, the bracket 31 is connected to the piston rod through a hinge bracket.

[0043] According to some embodiments of the present invention, the bracket 31 is arranged perpendicular to the discharging direction of the press 1.

[0044] According to some preferred embodiments of the present invention, the first platform 21 is a rotating table. After the titanium ingot is transported to the first platform 21, the rotating table drives the titanium ingot to rotate 90°, and the wider side of the titanium ingot contacts the pusher device 3, so as to facilitate the pusher device 3 to push the titanium ingot.

[0045] According to some preferred embodiments of the present invention, the second platform 22 is a cage turning assembly. After the pusher device 3 pushes two titanium ingots to the cage turning assembly, the cage turning assembly is used to assemble the two titanium ingots.

[0048] In this embodiment, by setting the push head 33, the force on the titanium ingot is ensured to be uniform, avoiding the titanium ingot from being knocked and damaged due to dislocation, and improving the product quality.

[0049] According to a titanium ingot electrode forming system provided by the present invention, as Figures 1 to 5 shown, the pusher device 3 further includes a fixing rod 34 and a guide sleeve 35. The guide sleeve 35 is fixedly arranged on the outer side wall of the cylinder block 322. The fixing rod 34 is fixedly connected to the second piston rod 323. The guide sleeve 35 is sleeved on the fixing rod 34 and is slidably matched with the fixing rod 34.

[0050] In this embodiment, by setting the fixing rod 34 and the guide sleeve 35 in cooperation, the cylinder block 322 and the second piston rod 323 are prevented from rotating during the movement process.

[0051] According to some preferred embodiments of the present invention, the guide sleeve 35 is arranged at a position horizontally behind on the outer side wall of the cylinder block 322.

[0052] According to a titanium ingot electrode forming system provided by the present invention, as Figures 1 to 5As shown, the pusher device 3 further includes a first guide rail 36 and a slider 37. The slider 37 is fixedly arranged at the bottom of the cylinder block 322, and the first guide rail 36 is fixedly arranged at the upper end of the bracket 31.

[0053] In this embodiment, by providing the first guide rail 36 and the slider 37, the movement accuracy of the cylinder block 322 is ensured, and deviation is avoided.

[0054] According to a titanium ingot electrode forming system provided by the present invention, as Figures 1 to 5 shown, the pusher device 3 further includes a limit block 38. The limit block 38 is arranged at one end of the first guide rail 36 close to the first piston rod 321 for limiting the recovery process of the cylinder block 322.

[0055] In this embodiment, by providing the limit block 38 to limit the recovery process of the cylinder block 322, it is ensured that the first piston rod 321 and the second piston rod 323 are completely recovered and fitted.

[0056] According to some embodiments of the present invention, when the first piston rod 321 and the second piston rod 323 are both completely recovered, the first end of the cylinder block 322 contacts and is limited by the limit block 38, and the second end of the first piston rod 321 and the first end of the second piston rod 323 are fitted and limited.

[0057] According to some preferred embodiments of the present invention, cross grooves are provided at the second end of the first piston rod 321 and the first end of the second piston rod 323 to ensure that when the first piston rod 321 and the second piston rod 323 are completely retracted and fitted, the oil can still flow back to the fuel tank along the grooves, and no additional back pressure will be generated.

[0058] According to a titanium ingot electrode forming system provided by the present invention, as Figures 1 to 5 shown, the pusher device 3 further includes a displacement detection component 39. The displacement detection component 39 is arranged at the second end of the first piston rod 321 for measuring the displacement of the second piston rod 323.

[0059] In this embodiment, by providing the displacement detection component 39, the position accuracy of the pusher device 3 is ensured, and accurate handling and positioning of the formed product can be achieved.

[0060] According to some preferred embodiments of the present invention, a wire drawing ruler pusher head displacement detection component 39 is arranged at one end of the bracket 31 close to the articulated frame. A wire drawing ruler pusher head displacement detection component interface is installed at a position slightly below the center of the pusher head 33 to form the displacement detection component 39. Avoidance holes are provided in the middle of the articulated frame and the limit block 38 for the wire drawing ruler pusher head displacement detection component 39 to pass through.

[0061] According to some preferred embodiments of the present invention, the displacement detection component 39 employs a displacement sensor.

[0062] According to some embodiments of the present invention, the pusher device 3 further includes a controller, which is used to read the displacement data of the pusher head 33, and then control the flow rate of the output pump and the output value of the servo valve, ensuring the accuracy of the position of the pusher device 3, and enabling precise handling and positioning of the formed product.

[0064] According to a titanium ingot electrode forming system provided by the present invention, as Figures 6 to 8 shown, the press 1 includes a lower crossbeam 11, an upper crossbeam 12, a lower die mechanism 13, and an upper die mechanism 14. The lower die mechanism 13 is fixedly connected to the lower crossbeam 11 through a first lifting assembly 15, and the upper die mechanism 14 is fixedly connected to the upper crossbeam 12 through a second lifting assembly 16.

[0065] According to some preferred embodiments of the present invention, the lower crossbeam 11 is of a welded structure, and a solid body made of 35# steel is nested and welded with a rib plate at the center corresponding to the electrode forming position.

[0066] According to a titanium ingot electrode forming system provided by the present invention, as Figures 6 to 8 shown, the lower die mechanism 13 includes a bottom die seat 131, a die core, and a die sleeve 132. The axis of the bottom die seat 131 coincides with the center line of the lower crossbeam 11, and the die core and the die sleeve 132 are installed at the upper end of the bottom die seat 131.

[0067] According to some embodiments of the present invention, the lower crossbeam 11 is provided with a lower die mechanism 13 at the upper part. The bottom die seat 131 in the lower die mechanism 13 is located at the central position of the upper part of the lower crossbeam 11. The bottom die seat 131 has a certain material contact strength, and its outer shape is slightly larger than the outer shape of the titanium ingot.

[0068] According to a titanium ingot electrode forming system provided by the present invention, the lower die mechanism 13 further includes a second pusher oil cylinder 133, a second guide rail 134, and a U-shaped stopper 135.

[0073] The technical solution of the present invention is further explained below in conjunction with a specific embodiment. It should be noted that this specific embodiment is only for those skilled in the art to better understand the technical solution of the present invention, and should not be regarded as an unreasonable limitation on the protection scope of the present invention.

[0074] Embodiment 1

[0075] After the titanium electrode titanium ingot is placed in the die sleeve and the die core die hole, the upper die mechanism moves downward for pressing. The forming force is transmitted to the bottom die seat through the product, and then diffused to the solid body in the center of the lower beam through the bottom die seat. After the pressing is completed, the first jacking component is started to lift the die sleeve, and the second push cylinder is started to drive the U-shaped block at the front end to move along the second guide rail laid on the lower cross beam to the lower end of the die sleeve. The first jacking component falls, and the lower end of the die sleeve contacts the top of the U-shaped block. At this time, the upper die mechanism moves downward again to squeeze the formed titanium electrode titanium ingot into the notch of the U-shaped block. After the titanium ingot is completely removed, the third push cylinder nested in the notch of the U-shaped push block is started to push the product to the specified position of the production line. Then, the third push cylinder retreats, the first jacking component starts to lift slightly, the second push cylinder retreats, and the first jacking component moves downward until the die sleeve contacts the bottom die seat, and the next working cycle can be carried out.

[0076] The third pushing cylinder in the mold transports the formed titanium ingot to the designated position of the rotating table. Further, the rotating table rotates the formed titanium ingot product 90° to make the stainless steel titanium ingot pusher in the pushing device at the center of the titanium ingot cross section vertical. Further, the pushing device receives the instruction from the program PLC to push the titanium ingot from the rotating table to the weighing table. After weighing, the pushing device pushes the titanium ingot to the rotating cage flipping assembly according to the program instruction. The rotating cage flipping assembly is a special equipment for rotating and splicing the pressed titanium pole blocks. After the rotating cage flipping assembly assembles the two titanium pole blocks, the pusher head in the pushing device receives the instruction to push the titanium ingot to the stacking table for stacking. The stacking table is composed of an unpowered roller. Under the action of the pushing device, benefiting from the high power density of the cylinder, the pressed products are stacked one by one in a push-to-front manner to form long strip electrodes with flat appearance and seams connected. At this point, a working cycle ends, and the pushing device retreats to wait for the next working cycle.

[0077] Compared with the prior art, the titanium ingot electrode forming system of the embodiment of the present invention has the following technical effects:

[0078] (1) Due to the concentrated load characteristics of the electrode pressing process, the lower crossbeam is embedded with a solid structure, which reduces the weight of the mold, simplifies the mold structure, and improves the stiffness of the lower crossbeam. Under the same conditions, the stiffness of the lower crossbeam is increased from about 1 / 6000 to 1 / 9000.

[0079] (2) The U-shaped stopper is nested with the second and third push cylinders. After the product is demoulded, the second push cylinder nested in the U-shaped stopper can push the product to the designated position of the production line, solving the problem of connection between processes during the pressing of titanium ingot electrodes.

[0080] (3) The third push cylinder in the lower die mechanism can also be used for dual purposes, with the function of mobile die changing. When maintaining the die punch and die core, the upper and lower die assemblies can be removed by removing the connection end with the die lifting cylinder, eliminating the need for the hydraulic press to be equipped with a mobile workbench function accessory;

[0081] (4) The working conditions are improved. In the process of pushing the formed titanium ingot, there is no need to repeatedly manipulate the bulky titanium block like a manual crowbar, and the number of operators can be reduced. It has the characteristics of reliable operation, labor saving, improved production efficiency and product quality, and meets the requirements of mass production of products.

[0082] (5) A pushing device is adopted, that is, through the cooperation of a single-cylinder double-piston-rod oil cylinder and a linear guide rail structure, and by using a displacement detection component of a wire-drawing ruler push head and a controller to accurately control the process position of the titanium ingot being pushed, the accuracy of the position of the pushing device is ensured, and accurate handling and positioning of the formed product can be realized. Compared with a professional manipulator, it has the characteristics of simple structure and control principle, convenient use, high reliability, low operation and manufacturing cost, and matching production capacity, good production connection and convenient operation, which has significant economic benefits for equipment users.

[0083] (6) By adopting the structure form of a single-cylinder double-piston-rod oil cylinder and a linear guide rail, the thickness dimension space of the two cylinder bottoms is saved, and the extending stroke of the output piston rod can be greatly increased in a limited space, the overall length and installation space are greatly reduced in the same stroke, or the output shaft stroke is greatly increased in the same space, with high space utilization rate and many usage scenarios, solving the long-stroke connection between the titanium ingot electrode pressing processes; at the same time, the two piston rods share the same cylinder barrel, the two piston rods are opposed, one cylinder has two output rods, and the cylinder body is movable; for the rear end of the oil cylinder, the rear cylinder moving rod is fixed; for the front end of the oil cylinder, the front rod moving cylinder is fixed. In this way, the overall stroke is divided into two parts, breaking it into smaller parts, realizing a large stroke through the relay of short-stroke hydraulic cylinders and having reliable support for each stroke segment, so that the second piston rod still maintains sufficient rigidity after connecting the push head and extending, ensuring the smoothness of pushing, solving the problem of the cantilever drooping of the piston rod end of the long-stroke oil cylinder after extension, avoiding the collision and damage of the titanium ingot product due to uneven pressing density of granular materials caused by the non-parallel action line of the second piston rod, and improving the product quality.
