Description

Technical Field

[0001] This invention relates to the field of mold technology, and specifically to a pressing mold and method for producing high-temperature corrosion-resistant nickel-based alloy bars. Background Technology

[0002] Corrosion-resistant nickel-based alloys are a class of alloys with nickel as the base element. Other elements (such as chromium, molybdenum, copper, iron, etc.) are usually added to enhance their corrosion resistance and high-temperature resistance. Due to their excellent chemical corrosion resistance and mechanical properties, these alloys are widely used in petrochemical, marine engineering, aerospace and other fields.

[0003] For example, the patent with authorization announcement number CN220560184U, authorization announcement date March 8, 2024, entitled "A self-cooling pressing mold for producing cemented carbide bars", includes a stamping base and a vertical plate. The vertical plate is vertically fixedly installed on the top of the stamping base. The patent is characterized by: a cooling cavity being formed inside the stamping base; a pressing device being provided on the stamping base; the pressing device including a stamping unit and a side pressing unit; the stamping unit and the side pressing unit being slidably connected; and a cooling unit being provided inside the cooling cavity and the side pressing unit; the stamping unit including a stamping block; stamping inclined plates being provided at both ends of the stamping block; a slot being formed inside the stamping block; an insertion block being provided inside the slot; an arc-shaped mounting block being provided at the bottom of the insertion block; an installation groove being formed inside the arc-shaped mounting block; an extrusion forming mold being provided inside the installation groove; an insertion rod being provided on the insertion block; and a stamping part being provided in the middle of the stamping base. This patented technology enables the round bar blank to be stamped left, right, up, and down by setting up a stamping unit and a side pressing unit, thereby greatly improving the forming speed of the round bar blank and thus improving the production efficiency of alloy bars. The cooling unit can quickly cool the round bar blank after stamping by using condensate and heat conduction, thereby avoiding the need for manual cooling by using clamping components, and improving the production efficiency of bars. For example, patent CN106216517B, authorized on November 30, 2018, entitled "A Stamping Moving Die with a Cooling Circulation Device," describes a moving die, a stationary die, and a cooling circulation device. The cooling circulation device is located on the moving die, which has a die head. The cooling circulation device includes an inner cooling circulation pipe and an outer cooling circulation device. The inner cooling circulation pipe is located inside the moving die and surrounds the die head, with an "L"-shaped cross-section. The outer cooling circulation device includes several nozzles and an outer cooling circulation pipe, which surrounds the outside of the moving die, with a trapezoidal cross-section for each nozzle. The inner cooling circulation pipe includes an inlet and an outlet, with the inlet connected to a water pump. The outer cooling circulation pipe has a circulating water inlet and a cold water inlet, with the outlet connected to the circulating water inlet and the cold water inlet connected to the water pump.

[0004] Although the aforementioned pressing mold or stamping die is equipped with a cooling unit or cooling circulation device to cool the pressed bar, the aforementioned cooling unit or cooling circulation device still uses a water pump as the driving source to drive the flow of coolant, which increases the cost, energy consumption and structural complexity; and the aforementioned pressing mold or stamping die does not have a mechanism to pry up the formed workpiece after pressing the bar, which makes the formed workpiece prone to getting stuck in the cavity, reducing the efficiency of pressing the workpiece. Summary of the Invention

[0005] The purpose of this invention is to provide a pressing mold and method for producing high-temperature corrosion-resistant nickel-based alloy bars, so as to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A pressing die for producing high-temperature corrosion-resistant nickel-based alloy bars includes an upper die and a lower die disposed directly below the upper die. When the upper die and the lower die are fully fitted together, multiple cavities for pressing nickel-based alloy bars are formed in the middle of the two cavities.

[0008] The upper mold includes a horizontal plate, the upper end of which is connected to a hydraulic device (not shown in the figure). Multiple pressure plates are evenly arranged along the length of the horizontal plate below it. The number of pressure plates is the same as the number of cavities. The pressure plates are used to form the cavities when the upper mold and the lower mold are fitted together.

[0009] The lower mold includes a base plate, a mounting plate is provided in the middle of the base plate, a plurality of forming grooves are provided on the mounting plate, the number of forming grooves is the same as the number of cavities, a forming assembly is provided inside the mounting plate, the forming assembly presses out nickel-based alloy rods through the plurality of cavities, and two guide posts are symmetrically arranged on the lower mold, and the two ends of the horizontal plate are slidably sleeved on the outside of the guide posts.

[0010] A molding assembly includes multiple side pressure block groups, the number of which is the same as the number of cavities. The side pressure block groups are slidably disposed on the mounting plate. A first vertical plate is disposed at one end of the mounting plate and is slidably disposed within the substrate. An elastic element is disposed between the first vertical plate and the substrate. Multiple protrusions are evenly disposed along the length of the first vertical plate near the mounting plate, the number of which is the same as the number of cavities. A placement groove is disposed at one end of the molding groove near the mounting plate, and the protrusions are disposed within the placement groove. A second vertical plate is disposed at the other end of the mounting plate. Both the first vertical plate and the second vertical plate are slidably disposed within the substrate.

[0011] A cooling assembly includes two housings containing coolant. The two housings are symmetrically arranged within a substrate. Two pump chambers are also symmetrically arranged within the substrate. Pump rods are slidably arranged within each pump chamber. A first cooling pipe is arranged between the pump chamber and the housing, located within the substrate and at the lower end of the cavity. A second cooling pipe is also arranged between the pump chamber and the housing. One-way valves are installed within both the first and second cooling pipes.

[0012] As described above, the substrate includes a horizontal portion and two vertical portions. The upper end of the horizontal portion has two vertical portions arranged symmetrically. The middle of the upper end of the horizontal portion has a mounting groove. The mounting plate is disposed in the mounting groove. The vertical portions have a sliding groove on their adjacent sides. The guide post is disposed in the sliding groove. The two ends of the horizontal plate are each slidably disposed in the sliding groove of one of the vertical portions.

[0013] As described above, the cross-section of the cavity is circular, and the cavity is composed of the pressure plate, the side pressure block assembly, and the forming groove.

[0014] As described above, the side pressure block assembly includes two side pressure blocks. Each side pressure block has two trapezoidal sliders symmetrically arranged at its lower end. Each trapezoidal slider is slidably disposed within the mounting plate, and a return spring is provided between each trapezoidal slider and the mounting plate.

[0015] As described above, a plurality of extrusion blocks are evenly arranged at the lower end of the horizontal plate along its length direction. The end of the extrusion block near the lower die is V-shaped. Each side pressure block has an inclined surface at its upper end. The V-shaped part at the lower end of the extrusion block can simultaneously extrude the inclined surface of the side pressure block.

[0016] As described above, the forming component also includes multiple steel wire ropes, each of which is slidably disposed within the horizontal portion. The steel wire ropes are used to connect the bottom of the first vertical plate and the second vertical plate. The two ends of the second vertical plate are provided with protruding portions, and a buffer spring is provided between the protruding portions and the horizontal portion.

[0017] The above-mentioned molding component further includes a plurality of fixed toothed plates, which are arranged along the length direction of the first vertical plate. The positions of the fixed toothed plates correspond to the positions of the pressure plate, and the fixed toothed plates are bolted to the first vertical plate. A sliding toothed plate is provided at one end of the pressure plate near the fixed toothed plates, and a compression spring is provided between the sliding toothed plate and the pressure plate.

[0018] As described above, the pump rod includes a pressure rod, which is slidably connected to the horizontal part. The vertical part has semi-circular grooves on both sides of the sliding groove, and the pressure rod is located in the semi-circular grooves. The end of the horizontal plate has two symmetrical semi-circular parts for pressing the pressure rod. A rubber block is provided at the upper end of the pressure rod, and a disc is provided in the middle of the pressure rod. A shock-absorbing spring is provided between the disc and the horizontal part. A piston is provided at the lower end of the pressure rod, and the piston is slidably disposed in the pump chamber.

[0019] As described above, the first cooling pipe is coiled below each of the forming grooves. The first cooling pipe is divided into two sections, one inside the mounting plate and the other inside the horizontal section. The two sections are connected by a plug-in connection. The first cooling pipe is also provided with two drain pipes. The drain pipes connect the lower end of the first cooling pipe to the upper end of one side of the box body. The drain pipes are also divided into two sections, one inside the mounting plate and the other inside the horizontal section.

[0020] A method for producing high-temperature corrosion-resistant nickel-based alloy bars, wherein the method is applicable to a pressing mold for producing high-temperature corrosion-resistant nickel-based alloy bars, and includes the following steps:

[0021] Step 1: Before pressing the corrosion-resistant nickel-based alloy rods, inspect the pressing mold, check the fit between the upper mold and the lower mold, check the integrity of the cavity formed by the pressure plate, the side pressure block group, and the forming groove, and check whether the connection between each component is stable and whether each component can slide normally.

[0022] Step 2: After mold inspection, multiple corrosion-resistant nickel-based alloys to be pressed are manually placed into the forming groove at one time. The hydraulic equipment lowers the horizontal plate, which is guided and limited by the guide post and the vertical section's sliding groove. This causes the horizontal plate to lower the pressure plate and the extrusion block, bringing them closer to the mounting plate. The V-shaped portion at the lower end of the extrusion block simultaneously extrudes multiple extrusion blocks, causing each extrusion block to drive its connected trapezoidal slider to press the return spring. The trapezoidal slider moves along the mounting plate, allowing the pressure plate, the side pressure blocks, and the forming groove to assemble into a cavity with a circular cross-section. This allows multiple pressure plates, side pressure blocks, and the mounting plate to simultaneously press multiple corrosion-resistant nickel-based alloys into rods. During the pressing process into a bar, the horizontal plate can squeeze the pressure rod through the semicircular portions at both ends, causing the pressure rod to squeeze the damping spring through the disc and drive the piston to descend along the pump chamber. This causes the piston to pump the coolant in the pump chamber into the first cooling pipe, allowing the cooling pipe coiled below the forming groove to flow and cool the pressed corrosion-resistant nickel-based alloy bar. The coolant in the first cooling pipe flows into the box body through the drain pipe. When the pressure plate, the side pressure block, and the forming groove are assembled into a cavity with a circular cross-section, the pressure plate drives the sliding toothed plate to squeeze the compression spring and slide it into the pressure plate. Under the action of the compression spring, the sliding toothed plate and the fixed toothed plate are engaged with each other, ensuring that the pressure plate can move smoothly to the designated position.

[0023] Step 3: The pressing mold presses the corrosion-resistant nickel-based alloy to be pressed into a rod and holds it under pressure for a period of time to maintain the shape of the formed rod. After the rod is formed, the horizontal plate is lifted by a hydraulic device. During the lifting, the horizontal plate is still guided and limited along the guide post and the groove of the vertical part. When the horizontal plate rises, it drives the pressure plate and the extrusion block to rise synchronously. When the extrusion block moves away from the side pressure plate, the return spring presses the trapezoidal slider, causing the trapezoidal slider to drive the side pressure block to move in the opposite direction and reset, so that the side pressure blocks move away from each other and expose the pressed corrosion-resistant nickel-based alloy rod, making it easy to remove the rod. When the pressure plate rises, it drives the sliding toothed plate to rise synchronously, so that the sliding toothed plate drives the fixed toothed plate that meshes with it to rise, thereby causing the fixed toothed plate to drive the first vertical plate to rise. The first vertical plate is raised, causing the second vertical plate to be pulled by multiple steel wire ropes. This causes the protruding part of the second vertical plate to press down the buffer spring, so that the second vertical plate retracts into the horizontal part and exposes the forming groove. At the same time, when the first vertical plate rises, it drives multiple protrusions to rise, so that the protrusions pry up the end of the pressed bar near the first vertical plate for easy unloading. In addition, when the horizontal plate rises, the shock-absorbing spring drives the pressure rod and the piston to rise along the pump chamber through the disc. In this way, the piston can transport the coolant in the box to the pump chamber through the second cooling pipe, so that the coolant circulates in the pump chamber, the first cooling pipe, the drain pipe, the box, and the second cooling pipe, which facilitates cooling during the pressing of the corrosion-resistant nickel-based alloy bar.

[0024] In the above technical solution, the beneficial effects of the present invention are as follows:

[0025] 1. The present invention uses a forming groove of a pressure plate and a mounting plate and a side pressure block assembly to form a cavity with a circular cross section, so as to press nickel-based alloy into rods from multiple directions. The upper and lower molds after separation allow the forming groove of the pressure plate and the mounting plate and the side pressure block assembly to separate from each other, so as to expose the formed rods for removal and collection.

[0026] 2. The present invention uses a horizontal plate to passively squeeze the pump rod, so that the pump rod passively drives the coolant to circulate in the pump chamber, the first cooling pipe, the drain pipe, the box and the second cooling pipe, thereby reducing the driving source to reduce costs and facilitating the cooling of the corrosion-resistant nickel-based alloy rod during the pressing process, so as to reduce the risk of burns to workers after the nickel-based alloy rod is shaped and the temperature is reduced.

[0027] 3. The present invention provides protrusions on the first vertical plate that are the same number as the number of cavities. When the first vertical plate rises with the pressure plate and the horizontal plate, it drives the protrusions to rise and pry up the pressed bar. This avoids the bar from getting stuck in the cavity and facilitates the quick unloading of the formed bar to improve the production efficiency of the bar.

[0028] 4. By setting up multiple identical pressure plates, forming grooves and side pressure block groups, the present invention enables multiple nickel-based alloys to be pressed into bars simultaneously in a multi-station mode during the process of the upper and lower molds being fitted together once (mold closing), thereby improving the production efficiency of nickel-based alloy bars.

[0045] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0046] In the description of this invention, it should be understood that the terms "upper", "lower", "vertical", "horizontal", "side", "inner", "outer", "one end", "the other end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0047] like Figure 1-13As shown, the present invention provides a pressing mold for producing high-temperature corrosion-resistant nickel-based alloy bars, including an upper mold 1 and a lower mold 2 disposed directly below the upper mold 1. When the upper mold 1 and the lower mold 2 are fully fitted together, a plurality of cavities 3 for pressing nickel-based alloy bars are formed in the middle of the two.

[0048] The upper mold 1 includes a horizontal plate 10. Multiple pressure plates 100 are evenly arranged below the horizontal plate 10 along its length. The number of pressure plates 100 is the same as the number of cavities 3. The pressure plates 100 are used to form cavities 3 when the upper mold 1 and the lower mold 2 are fitted together.

[0049] The lower mold 2 includes a base plate 21, a mounting plate 22 is provided in the middle of the base plate 21, and a plurality of forming grooves 220 are provided on the mounting plate 22. The number of forming grooves 220 is the same as the number of cavities 3. A forming component 23 is provided inside the mounting plate 22. The forming component 23 presses out nickel-based alloy rods through the plurality of cavities 3. Two guide posts 20 are symmetrically arranged on the lower mold 2. The two ends of the horizontal plate 10 are slidably sleeved on the outside of the guide posts 20.

[0050] The molding assembly 23 includes multiple side pressure block groups 230, the number of which is the same as the number of cavities 3. The side pressure block groups 230 are slidably mounted on the mounting plate 22. A first vertical plate 231 is provided at one end of the mounting plate 22. The first vertical plate 231 is slidably mounted within the substrate 21, and an elastic element 2310 is provided between the first vertical plate 231 and the substrate 21. The side of the first vertical plate 231 closest to the mounting plate 22 extends along its length... A plurality of protrusions 232 are evenly arranged, the number of protrusions 232 being the same as the number of cavities 3. A placement groove is provided at one end of the molding groove near the mounting plate 22, and the protrusions 232 are placed in the placement groove. When the upper end of the protrusion 232 is arc-shaped and it is placed in the placement groove, the arc-shaped structure of the upper end of the protrusion 232 is on the same curved surface as the groove surface of the molding groove 220. A second vertical plate 233 is provided at the other end of the mounting plate 22. Both the first vertical plate 231 and the second vertical plate 233 are slidably arranged in the substrate 21.

[0051] Cooling assembly 4 includes two housings 40 containing coolant. The two housings 40 are symmetrically arranged in the substrate 21. Two pump chambers 41 are also symmetrically arranged in the substrate 21. Pump rods 42 are slidably arranged in the pump chambers 41. A first cooling pipe 43 is arranged between the pump chambers 41 and the housings 40. The first cooling pipe 43 is located in the substrate 21 and at the lower end of the cavity 3. A second cooling pipe 44 is also arranged between the pump chambers 41 and the housings 40. One-way valves 45 are arranged in the first cooling pipe 43 and the second cooling pipe 44.

[0052] In another embodiment of the present invention, the substrate 21 includes a horizontal portion 210 and two vertical portions 211. The upper end of the horizontal portion 210 is provided with two vertical portions 211 in a symmetrical manner. A mounting groove is provided in the middle of the upper end of the horizontal portion 210. The mounting plate 22 is disposed in the mounting groove. A sliding groove is provided on the side of the vertical portions 211 that are close to each other. The guide post 20 is disposed in the sliding groove. The two ends of the horizontal plate 10 are each slidably disposed in the sliding groove of one of the vertical portions 211.

[0053] The specific implementation method is as follows: the mounting groove is used to place and fix the mounting plate 22, and the sliding groove of each vertical part 211 can guide and limit one end of the horizontal plate 10 to prevent the horizontal plate 10 from shifting during the lifting and lowering process.

[0054] In another embodiment of the present invention, the cross-section of the cavity 3 is circular, and the cavity 3 is composed of a pressure plate 100, a side pressure block group 230 and a molding groove 220;

[0055] The specific implementation method is as follows: the cross-section of the cavity 3 is circular so that the corrosion-resistant nickel-based alloy pressed by the cavity 3 can be formed into a rod. The cavity 3 is composed of a pressure plate 100, a side pressure block group 230 and a forming groove 220. When the hydraulic equipment drives the horizontal plate 10 to descend and approach the mounting plate 22, the pressure plate 100, the side pressure block group 230 and the forming groove 220 approach each other to form a cavity 3 with a circular cross-section, so that the cavity 3 presses the corrosion-resistant nickel-based alloy into a rod. After pressing, the hydraulic equipment drives the horizontal plate 10 to rise, so that the pressure plate 100, the side pressure block group 230 and the mounting plate 22 separate from each other, so as to remove the pressed corrosion-resistant nickel-based alloy rod.

[0056] In another embodiment of the present invention, the side pressure block group 230 includes two side pressure blocks 2300. Two trapezoidal sliders 2301 are symmetrically arranged at the lower end of each side pressure block 2300. Each trapezoidal slider 2301 is slidably arranged in the mounting plate 22, and a reset spring 2302 is provided between each trapezoidal slider 2301 and the mounting plate 22.

[0057] The specific implementation method is as follows: When the hydraulic equipment drives the horizontal plate 10 to descend, the horizontal plate 10 can simultaneously squeeze each side pressure block 2300, so that each side pressure block 2300 drives the two trapezoidal sliders 2301 connected to it to squeeze the return springs 2302 and move closer along the mounting plate 22, so that the two side pressure blocks 2300 in the same group move closer to each other and closer to each other with the pressure plate 100 and the forming groove 220 to form the cavity 3 to press the bar; after the bar is pressed and formed, the hydraulic equipment drives the horizontal plate 10 to move upward. At this time, the horizontal plate 10 gradually releases the squeezing of each side plate. In this way, each return spring 2302 can squeeze the trapezoidal sliders 2301 connected to it to move and reset along the mounting plate 22 in the opposite direction, so that the trapezoidal sliders 2301 drive the side pressure blocks 2300 connected to them to move and reset and expose the pressed and formed corrosion-resistant nickel-based alloy bar, which is convenient to remove and collect.

[0058] In another embodiment of the present invention, a plurality of extrusion blocks 101 are uniformly arranged at the lower end of the horizontal plate 10 along its length direction. The end of the extrusion block 101 near the lower mold 2 is V-shaped. Each side pressure block 2300 has an inclined surface 1010 at its upper end. The V-shaped part at the lower end of the extrusion block 101 can simultaneously extrude the inclined surface 1010 of the side pressure block 2300.

[0059] The specific implementation method is as follows: Multiple extrusion blocks 101 are arranged along the length of the horizontal plate 10. The lower end of each extrusion block 101 is V-shaped. Thus, the hydraulic equipment drives the extrusion blocks 101 down towards the mounting plate 22 via the horizontal plate 10. This causes the V-shaped portions at the lower ends of the multiple extrusion blocks 101 to simultaneously extrude the inclined surfaces 1010 of the side pressure blocks 2300. Consequently, two side pressure blocks 2300 within the same group approach each other and are assembled in the forming grooves 220 of the pressure plate 100 and the mounting plate 22 to form a circular cavity 3, so that the two side... The forming groove 220 of the pressure block 2300, pressure plate 100 and mounting plate 22 presses the corrosion-resistant nickel-based alloy into a rod. After the corrosion-resistant nickel-based alloy rod is pressed into shape, the hydraulic equipment drives multiple extrusion plates 100 to rise away from the mounting plate 22 through the horizontal plate 10. This causes the V-shaped part of the extrusion plate 100 to gradually move away from the inclined surface 1010 of the side pressure block 2300, thereby causing the return spring 2302 to press the trapezoidal slider 2301 and drive the side pressure block 2300 to move in the opposite direction to reset, so as to remove and collect the corrosion-resistant nickel-based alloy rod.

[0060] In another embodiment of the present invention, the molding component 23 further includes a plurality of steel wire ropes 234, each steel wire rope 234 being slidably disposed within the horizontal portion 210. The steel wire ropes 234 are used to connect the bottom of the first vertical plate 231 and the second vertical plate 233. The two ends of the second vertical plate 233 are provided with protrusions 235, and a buffer spring 236 is provided between the protrusions 235 and the horizontal portion 210.

[0061] The specific implementation method is as follows: The first vertical plate 231 and the second vertical plate 233 can seal both ends of the cavity 3 to prevent the corrosion-resistant nickel-based alloy pressing rod from being exposed from both ends of the cavity 3 during the pressing process. After the rod is pressed and formed, the first vertical plate 231 is driven to rise under the action of the forming component 23, so that the first vertical plate 231 drives the protrusion 232 to rise and pry up one end of the pressed plate close to the first vertical plate 231. During the rising process of the first vertical plate 231, the first vertical plate 231 squeezes the elastic element 2310 and pulls the second vertical plate 233 through multiple steel wire ropes 234, so that the second vertical plate 233 drives the protrusion 235 to squeeze the buffer spring 236 to move downward along the horizontal part 210, thereby releasing the second vertical plate 233 that has retracted the horizontal part 210 from sealing one end of the cavity 3, so that the rod pried up by the protrusion 232 can be removed.

[0062] In another embodiment of the present invention, the molding component 23 further includes a plurality of fixed toothed plates 237, which are arranged along the length of the first vertical plate 231. The positions of the fixed toothed plates 237 correspond to the positions of the pressure plate 100. The fixed toothed plates 237 are bolted to the first vertical plate 231. A sliding toothed plate 238 is provided at one end of the pressure plate 100 near the fixed toothed plates 237. A compression spring 239 is provided between the sliding toothed plate 238 and the pressure plate 100.

[0063] The specific implementation method is as follows: When the hydraulic equipment drives the pressure plate 100 to descend through the horizontal plate 10 to form the cavity 3, the fixed toothed plate 237 and the sliding toothed plate 238 are pressed against each other. In this way, the sliding toothed plate 238 can push the compression spring 239 and move into the pressure plate 100, so that the sliding toothed plate 238 and the fixed toothed plate 237 can move and lock together during the mutual meshing process, so that the pressure plate 100 can smoothly reach the designated position to press the corrosion-resistant nickel-based alloy rod. After the corrosion-resistant nickel-based alloy rod is pressed and formed, when the hydraulic equipment drives the pressure plate 100 to rise through the horizontal plate 10, the compression spring 239 can squeeze the sliding toothed plate 238 to move outward from the pressure plate 100, so that the sliding toothed plate 238 and the fixed toothed plate 237 that are locked together rise synchronously with the pressure plate 100. Thus, the fixed toothed plate 237 drives the second vertical plate 233 through the first vertical plate 231 and the wire rope 234 to compress the buffer spring 236 along the horizontal part 2. 10 moves downwards, at which point the first vertical plate 231 also compresses the elastic element 2310, thereby causing the second vertical plate 233, which has retracted to the horizontal part 210, to release the seal on one end of the cavity 3, so that the rod pried up by the protrusion 232 can be removed; and after the first vertical plate 231 rises to a certain height and stops moving, the teeth of the fixed toothed plate 237 compress the teeth of the sliding toothed plate 238, causing the sliding toothed plate 238 to push the compression spring 239 again and cause the sliding toothed plate 238 moves into the pressure plate 100 so that the sliding toothed plate 238 and the fixed toothed plate 237 are separated from each other. Thus, under the action of the elastic member 2310, the first vertical plate 231 descends vertically along the horizontal portion 210 to reset, and at the same time, under the action of the buffer spring 236, the second vertical plate 233 rises vertically along the horizontal portion 210 to reset. This allows the second vertical plate 233 to drive the first vertical plate 231 to descend and reset via multiple steel wire ropes 234 so that they can be pressed together again.

[0064] In another embodiment of the present invention, the pump rod 42 includes a pressure rod 420, which is slidably connected to the horizontal part 210. The vertical part 211 has semi-circular grooves on both sides of the sliding groove, and the pressure rod 420 is located in the semi-circular grooves. The end of the horizontal plate 10 is symmetrically provided with two semi-circular parts 102, which are used to squeeze the pressure rod 420. The upper end of the pressure rod 420 is provided with a rubber block 421, and the middle part of the pressure rod 420 is provided with a disc 422. A shock-absorbing spring 423 is provided between the disc 422 and the horizontal part 210. The lower end of the pressure rod 420 is provided with a piston 424, which is slidably disposed in the pump chamber 41.

[0065] The specific implementation method is as follows: When the hydraulic equipment drives the horizontal plate 10 to descend, the semicircular portion 102 of the horizontal plate 10 can squeeze the pressure rod 420, causing the pressure rod 420 to drive the disc 422 to squeeze the shock-absorbing spring 423. This causes the pressure rod 420 to drive the piston 424 to descend along the pump chamber 41, allowing the piston 424 to transport the coolant in the pump chamber 41 to the first cold zone pipe. This allows the flowing coolant in the first cooling pipe 43, which is coiled below the forming groove 220, to carry away the heat after pressing into the rod, and the coolant in the first cooling pipe 43 can be discharged into the housing 40. When the hydraulic equipment drives the horizontal plate 10 to rise... When the semicircular portion 102 of the horizontal plate 10 releases its pressure on the pressure plate 100, the shock-absorbing spring 423 can drive the pressure plate 100 to rise and reset via the disc 422, thereby causing the pressure rod 420 to drive the piston 424 to rise along the pump chamber 41, so that the coolant in the housing 40 can flow into the pump chamber 41 through the second cooling pipe 44. The one-way valve 45 provided on the first cooling pipe 43 and the second cooling pipe 44 allows the coolant to circulate in the pump chamber 41, the first cooling pipe 43, the drain pipe 46, the housing 40 and the second cooling pipe 44, which facilitates cooling during the pressing of the corrosion-resistant nickel-based alloy rod.

[0066] In another embodiment of the present invention, the first cooling pipe 43 is coiled below each forming groove 220. The first cooling pipe 43 is divided into two sections, one section is inside the mounting plate 22 and the other section is inside the horizontal part 210. The two sections are connected by a plug-in connection. The first cooling pipe 43 is also provided with two drain pipes 46. The drain pipes 46 connect the lower end of the first cooling pipe 43 to the upper end of one side of the box body 40. The drain pipes 46 are also divided into two sections, one section is inside the mounting plate 22 and the other section is inside the horizontal part 210.

[0067] The specific implementation method is as follows: the first cooling pipe 43 and the drain pipe 46 are both divided into two sections, and one section of each is set in the mounting plate, while the other section of each is set in the horizontal part 210. Thus, when the mounting plate 22 is installed in the mounting groove of the horizontal part 210, the section of the first cooling pipe 43 in the mounting plate 22 and the section of the first cooling pipe 43 in the horizontal part 210 are interlocked and connected, and the section of the drain pipe 46 in the mounting plate 22 and the section of the drain pipe 46 in the horizontal part 210 are interlocked and connected. In this way, the coolant can circulate in the pump chamber 41, the first cooling pipe 43, the drain pipe 46, the housing 40 and the second cooling pipe 44, which facilitates the cooling of the corrosion-resistant nickel-based alloy rod during the pressing process.

[0068] A method for producing high-temperature corrosion-resistant nickel-based alloy bars, the method being applicable to a pressing mold for producing high-temperature corrosion-resistant nickel-based alloy bars, includes the following steps:

[0069] Step 1: Before pressing the corrosion-resistant nickel-based alloy rods, inspect the pressing mold, check the fit between the upper mold 1 and the lower mold 2, check the integrity of the cavity 3 composed of the pressure plate 100, the side pressure block group 230, and the forming groove 220, and check whether the connection between each component is stable and whether each component can slide normally.

[0070] Step 2: After mold inspection, multiple pieces of corrosion-resistant nickel-based alloy to be pressed are manually placed into the forming groove 220. The hydraulic equipment lowers the horizontal plate 10. As the horizontal plate 10 descends, it is guided and limited by the guide posts 20 and the sliding grooves of the vertical part 211. These grooves prevent the horizontal plate 10 from shifting during lifting. The hydraulic equipment lowers the extrusion blocks 101 via the horizontal plate 10, bringing them closer to the mounting plate 22. This causes the V-shaped portions at the lower ends of multiple extrusion blocks 101 to simultaneously press the inclined surfaces 1010 of the side pressure blocks 2300. This brings two side pressure blocks 2300 within the same group closer together, assembling them in the forming groove 220 of the pressure plate 100 and mounting plate 220 to form a circular cavity 3. This allows the two side pressure blocks 2300, the pressure plate 100, and the forming groove 220 of the mounting plate 22 to press the corrosion-resistant nickel-based alloy into rods. During the pressing process of the corrosion-resistant nickel-based alloy to be pressed into rods... The horizontal plate 10 can press the pressure rod 420 through the semicircular portions 102 at both ends, so that the pressure rod 420 presses the shock-absorbing spring 423 through the disc 422 and drives the piston 424 to descend along the pump chamber 41, so that the piston 424 pumps the coolant in the pump chamber 41 into the first cooling pipe 43, so that the cooling pipe in the first cooling pipe 43 coiled below the forming groove 220 flows to cool the pressed corrosion-resistant nickel-based alloy rod, and the coolant in the first cooling pipe 43 flows into the box 40 through the drain pipe 46; when the pressure plate 100, the side pressure block 2300 and the forming groove 220 are assembled into a cavity 3 with a circular cross-section, the pressure plate 100 drives the sliding toothed plate 238 to press the compression spring 239 to slide into the pressure plate 100, and under the action of the compression spring 239, the sliding toothed plate 238 and the fixed toothed plate 237 are locked together to ensure that the pressure plate 100 can move smoothly to the designated position to press the corrosion-resistant nickel-based alloy rod;

[0071] Step 3: The pressing mold presses the corrosion-resistant nickel-based alloy to be pressed into a rod and holds it under pressure for a period of time to maintain the shape of the formed rod. After the rod is formed, the horizontal plate 10 is raised by the hydraulic equipment. During the rise, the horizontal plate 10 is still guided and limited by the grooves of the guide column 20 and the vertical part 211. When the horizontal plate 10 rises, it drives the pressure plate 100 and the extrusion block 101 to rise synchronously. When the extrusion block 101 moves away from the side pressure plate 100, the return spring 2302 presses the trapezoidal slider 2301, so that the trapezoidal slider 2301 drives the side pressure block 2300 to move in the opposite direction and reset, so that the side pressure blocks 2300 move away from each other and expose the pressed corrosion-resistant nickel-based alloy rod, making it easy to remove the rod. When the pressure plate 100 rises, the extrusion block 100 moves away from the side pressure plate 100 to maintain the shape of the rod. The compression spring 239 can compress the sliding toothed plate 238, causing it to tend to move outwards from the pressure plate 100. This causes the sliding toothed plate 238 and its interlocking fixed toothed plate 237 to rise synchronously with the pressure plate 100. Consequently, the fixed toothed plate 237, through the first vertical plate 231 and the wire rope 234, drives the second vertical plate 233 to compress the buffer spring 236 and move downwards along the horizontal portion 210. At this time, the first vertical plate 231 also compresses the elastic element 2310, thereby causing the second vertical plate 233, which has retracted into the horizontal portion 210, to release the seal on one end of the cavity 3, so that the rod pried up by the protrusion 232 at one end can be removed. After the first vertical plate 231 rises to a certain height, it stops moving. At this time, the fixed toothed plate 237... The teeth of the sliding toothed plate 238 are pressed against the teeth of the sliding toothed plate 238, causing the sliding toothed plate 238 to push the compression spring 239 again and move the sliding toothed plate 238 into the pressure plate 100, so that the sliding toothed plate 238 and the fixed toothed plate 237 are separated from each other. Thus, under the action of the elastic member 2310, the first vertical plate 231 descends vertically along the horizontal portion 210 to reset, and at the same time, under the action of the buffer spring 236, the second vertical plate 233 rises vertically along the horizontal portion 210 to reset. This allows the second vertical plate 233 to drive the first vertical plate 231 to descend and reset via multiple steel wire ropes 234 for re-pressing. At the same time, when the first vertical plate 231 rises, it drives multiple protrusions 232 to rise, so that the protrusions 232 will... After pressing and forming, the end of the bar closest to the first vertical plate 231 is pried up for easy unloading. In addition, when the horizontal plate 10 rises, the semicircular part 102 of the horizontal plate 10 releases the pressure on the pressure plate 100. In this way, the shock-absorbing spring 423 can drive the pressure plate 100 to rise and reset through the disc 422, thereby causing the pressure rod 420 to drive the piston 424 to rise along the pump chamber 41, so that the coolant in the housing 40 flows into the pump chamber 41 through the second cooling pipe 44. The one-way valve 45 provided on the first cooling pipe 43 and the second cooling pipe 44 allows the coolant to circulate in the pump chamber 41, the first cooling pipe 43, the drain pipe 46, the housing 40 and the second cooling pipe 44, which facilitates the cooling of the corrosion-resistant nickel-based alloy bar during the pressing process.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

Step 2: After the mold inspection is completed, multiple corrosion-resistant nickel-based alloys to be pressed are manually placed into the forming groove (220) at one time, and the hydraulic equipment drives the horizontal plate (10) to descend.
