Description

Technical Field

[0001] This invention relates to the field of special material heat treatment technology, and in particular to a high-temperature alloy cake hard packaging equipment. Background Technology

[0002] High-temperature alloys are a class of metallic materials based on iron, nickel, and cobalt that can still function normally according to design requirements under high temperatures and stress. They are alloy materials with special chemical compositions, produced using special processes, and designed to meet specific needs. High-temperature alloys can resist oxidation, corrosion, and creep at temperatures of 600-1200℃ and can operate for extended periods under high mechanical stress. Therefore, they are widely used as key materials for various high-temperature resistant components required by aero-engines, marine turbine engines, and energy and chemical industries.

[0003] In the production of high-temperature alloys, temperature control in the forging process is crucial to obtaining high-quality alloy products. However, the temperature control window for the critical forging process in the production of high-temperature alloys is very narrow. In order to reduce temperature loss, the transfer time of the billet after exiting the furnace usually needs to be accurate to the second. Therefore, temperature control is a key factor affecting the mechanical properties of high-temperature alloys during hot working.

[0004] In actual production, to ensure good forgeability, the billet is usually wrapped using methods such as sheathing to reduce heat loss during hot working and transfer. The better the insulation effect of the wrapping material, the better the deformable microstructure properties obtained. Sheathing refers to covering the surface of the billet with insulating materials such as aluminum silicate fiber blankets to slow down heat loss caused by thermal radiation and convection, prevent heat transfer between the mold and the billet, and block heat transfer between the billet and the air. Methods for fixing the insulating material to the billet surface are divided into hard sheathing and soft sheathing. Hard sheathing uses a welded stainless steel outer sleeve for fixation, while soft sheathing uses an adhesive method.

[0005] Currently, factories primarily rely on manual labor to directly wrap raw materials. This method is labor-intensive, involves harsh working conditions, and has low production efficiency. Meanwhile, the construction of intelligent "lights-out" factories demands automation at every stage of the process. Therefore, developing an automated rigid packaging equipment is both necessary and beneficial for improving production efficiency, ensuring product quality, and building automated factories.

[0033] like Figure 3 As shown, the cake lifting mechanism 2 includes a worm gear screw jack (201) and a supporting frustum (202); the worm gear screw jack (201) is fixed inside the limiting frame (103); the supporting frustum (202) is coaxially arranged above the limiting cylinder (104) to support the cake; the output end of the worm gear screw jack (201) passes axially through the supporting platform (102) and the limiting cylinder (104) from bottom to top and is coaxially fixed to the bottom of the supporting frustum (202) to drive the supporting frustum (202) to achieve axial lifting.

[0034] like Figure 4-6 As shown, the steel plate forming mechanism 3 includes a worm gear rotary bearing (301), a disc cam (302), an extrusion assembly, and a pusher frame (308); the disc cam (302) is coaxially disposed above the limiting cylinder (104), and the supporting frustum (202) is located above the disc cam (302); the worm gear rotary bearing (301) is fixed on one side of the upper surface of the supporting platform (102), and its working end is coaxially connected to the bottom of the disc cam (302) for driving the disc cam (302); in this embodiment, the pusher frame (308) is provided with five The components are arranged in a circular pattern on the outer side of the disc cam (302) and their bottoms are fixed to the upper surface of the support platform (102). The sides of each pusher frame (308) are connected to each other as a whole by a connecting rod. The top surface of each pusher frame (308) has a groove (309) along the radial direction of the disc cam (302). The extrusion components are respectively arranged on the top of each pusher frame (308) and their bottoms are respectively slidably connected to the groove (309).

[0035] In this embodiment, the extrusion assembly includes a pusher block (303), a clamping block base (304), and a clamping block (305); the pusher block (303) is slidably connected in the slide groove (309), and the lower end face of the pusher block (303) is radially evenly distributed with racks (310) that mesh with the disc cam (302) to realize the radial movement of the pusher block (303); the clamping block base (304) is fixedly connected to the pusher block (303). The top of the plate is positioned with its working surface facing radially inward. The push block (303) can drive the pressing block base (304) to move radially. The pressing blocks (305) are respectively hinged laterally to the left and right sides of the working surface of each pressing block base (304) to move radially together with the push block (303), so that the steel plate is shaped into an undevelopable curved surface. The working surface of the pressing block (305) is provided with a cross groove in the middle to ensure that different sized plates have four points of contact on each pressing block (305). The working surface of the pressing block (305) has an arc-shaped structure, and its longitudinal curved surface radius is taken as the highest plate curved surface radius in the same group, and its transverse curved surface radius is taken as the largest diameter plate curved surface radius in the same group.

[0039] The specific working process and principle of using the present invention for hard-packing alloy discs are as follows:

[0040] Step S1: Pre-treat the steel plate, such as... Figure 8As shown, the upper and lower steel plates are each processed into ten petals in the shape of "petals"; the petals of the upper steel plate are bent at 55° and the petals of the lower steel plate are bent at 50°; the upper and lower steel plates are fixed with insulation cotton respectively; the number of the push block (303) and the pressing block base (304) is half the number of petals of the pre-treated steel plate; the number of the pressing block (305) and the rubber block (306) is consistent with the number of petals of the pre-treated steel plate.

[0041] Step S2: Place the cake blanks; according to the cake blank specifications, the worktable is raised to the corresponding height so that the half-height of all the cake blanks is on the same horizontal plane. The pre-treated lower steel plate is placed in the center of the support frustum (202), and the robotic arm places the cake blank in the center of the support frustum (202). The sides of the cake blank are wrapped with cut insulation cotton, and then the pre-treated upper steel plate is placed on top of the cake blank. The pressure plate drive module (401) drives the pressure plate (403) through the parallelogram mechanism (402) to press the upper steel plate and insulation cotton onto the cake blank, preventing the steel plate and insulation cotton from moving.

[0042] Step S3: Steel plate forming; the worm gear turntable bearing (301) drives the disc cam (302) to rotate, which drives the push block (303) and the clamping block (305) to move radially, thereby radially clamping the steel plate. At this time, the upper steel plate petals are inside and the lower steel plate petals are outside, making it into an undevelopable curved surface.

[0043] Step S4: Welding the steel plate; the worm gear turntable bearing (301) drives the disc cam (302) to rotate, causing the push block (303) and clamping block (305) to move radially back to the initial position. The welding robot welds ten welding points according to the planned path, such as... Figure 9 As shown.

[0044] Step S5: The pressure plate drive module (401) drives the pressure plate (403) to return to its initial position, the transfer robotic arm clamps the packaged cake, transfers the cake, and the equipment returns to its initial state.
