Description

Technical Field

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

[0002] High-temperature alloys, also known as heat-resistant alloys or superalloys, are a class of metallic materials that can continue to function normally and reliably for extended periods under high temperatures and stress. High-temperature alloys operate under harsh conditions, typically at 600-1200°C, in oxidizing and corrosive environments, and under complex stress conditions such as high- and low-cycle fatigue or creep. Therefore, they are widely used in hot-end components of aero-engines, various high-temperature components in rocket engines, and high-temperature, corrosion-resistant components required by energy and chemical industries. Consequently, the quality and performance of high-temperature alloys are crucial for the development and safety of these fields.

[0003] In the production of high-temperature alloys, to obtain materials with various excellent properties, it is necessary to ensure good microstructural stability and reliability, such as a fine-grained or ultrafine-grained microstructure. Therefore, temperature control in the forging process is crucial. Furthermore, the temperature control window for critical forging processes is very small, meaning the forging temperature range is narrow. To minimize temperature loss, the transfer time of forgings after exiting the furnace typically needs to be accurate to the second. Therefore, temperature control is one of the key process parameters during hot working.

[0004] In actual production, to ensure forgeability, the heating temperature of forgings is usually set at the upper limit of the deformable temperature range, and methods such as sheathing are used to insulate the forgings to slow down heat loss during the transfer and hot working processes. The higher the insulation efficiency of the insulation material and the shorter the transfer and deformation time of the billet, the better the deformed microstructure properties. Sheathing refers to wrapping the surface of the forging with insulating materials such as aluminum silicate fiber blankets to reduce heat loss caused by thermal radiation and convection, prevent heat transfer between the die and the forging, and block heat transfer between the forging and the air. There are two ways to fix the insulating material to the surface of the forging: hard sheathing and soft sheathing. Hard sheathing uses a welded stainless steel outer sleeve for fixation, while soft sheathing uses an adhesive method for fixation.

[0005] Currently, factories typically use manual packaging to wrap forgings. This method involves high labor intensity, harsh working conditions, and significant fluctuations in packaging time and quality. Therefore, there is an urgent need for an automated packaging device to improve production efficiency and ensure product quality.

[0006] For example, utility model patent No. 201922422514.7 discloses a heat preservation device for steel ingots or billets in the high-temperature alloy forging process. It employs multiple symmetrically arranged robotic arms, each consisting of several joints, and each joint is individually driven by a cylinder or hydraulic cylinder. The robotic arms wrap self-adhesive heat-insulating blankets around the bar stock. However, the technology used only wraps the cylindrical surface, and the drive mechanism is complex and requires multiple controls. Summary of the Invention

[0041] like Figure 10-13As shown, the end-face packaging mechanism 4 includes a gear cover 401, an end-face rotation drive module 402, an end-face translation slider module 403, an end-face translation drive module 404, an auxiliary pressure plate 405, a folding block 406, an auxiliary pressure plate spring 407, a folding block hinge support 408, a folding block spring 409, an end-face rotation bracket 410, a slewing bearing 411, an active-side end-face frame 412, and a passive-side end-face frame 413. The active-side end-face frame 412 and the passive-side end-face frame 413 are respectively arranged on the left and right sides above the frame 1. The slewing bearing 411 is coaxially arranged on the inner end faces of the active-side end-face frame 412 and the passive-side end-face frame 413. The gear cover 401 is fixed on the upper inner side of the active-side end-face frame 412 and the passive-side end-face frame 413 and is located on the outer side of the circumference of the slewing bearing 411 to protect the gear.

Both end face translation drive modules 404 are composed of a drive motor and a lead screw and nut. The lead screw and nut on both sides are fixedly connected to the bottom of the active end face frame 412 and the passive end face frame 413, respectively. The top of the auxiliary pressure plate 405 is provided with a semi-cylindrical protrusion, which is engaged with the top groove of the folding block 406 and can swing around the groove at a certain angle.

The folding block hinge support 408 is evenly distributed around the circumference of the inner wall of the end face rotating bracket 410 on the axial side. There are multiple folding block hinge supports 408, which are evenly distributed around the axis of the rotating bracket 410. The number is consistent with the number of end face pre-processed steel plate petals. In this embodiment, there are six. The folding blocks 406 are hinged one-to-one inside the folding block hinge support 408; the folding block springs 409 are evenly distributed circumferentially between the folding blocks 406 and the end face rotation bracket 410, with one end hinged to the lower part of the folding blocks 406 and the other end hinged to the inner end face of the end face rotation bracket 410.

The number of lobes is consistent with the number of lobes of the end face pre-treated steel plate, which is six in this embodiment. The telescopic frame 501 is fixedly connected to the nut of the telescopic clamping drive module 503 and can follow the movement of the telescopic clamping drive module 503. The telescopic guide slider module 502 consists of guide rails and sliders. The guide rails are evenly distributed around the circumference and fixed inside the axis corresponding to the multi-lobed structure of the end face rotating bracket 410 and the multi-lobed structure of the telescopic frame 501.

In this embodiment, each guide rail has two sliders. There are multiple telescopic guide slider modules 502, which are evenly distributed around the axis of the telescopic frame 501, which is three in this embodiment. The telescopic clamping drive module 503 is coaxially fixed to the outside of the end face rotating bracket 410 and can rotate with the end face rotating bracket 410.

[0043] The specific working process and principle of using the present invention for hard sheathing of bar stock are as follows:

[0044] Step S1: Pre-treatment of the cylindrical steel plate, such as Figure 14 As shown in Figure a, the middle section is bent at a 140° angle, with one end bent into a 25mm long, 120° bend, and the corresponding insulation cotton is then attached to the steel plate. Figure 5 As shown, the pre-treated steel plate and insulation cotton are placed on the column steel plate positioning frame 312 for positioning.

[0045] Step S2: Transfer the bar stock to the steel plate and release it on the V-block 201.

[0046] Step S3: Adjust the center position of the bar stock, such as... Figure 3 The bar stock center position is adjusted by the bar stock lifting system 2 to make the bar stock coaxial with the end face rotating bracket 410. The bar stock lifting system 2 is driven by a servo motor 205 and moves up and down through a worm gear screw jack 204. The lifting guide slider module 206 is responsible for counteracting unbalanced loads, and the lifting limit block 203 prevents the lifting top plate 202 from falling suddenly and protects the screw of the worm gear screw jack 204.

[0047] Step S4: Axial fixation of the bar stock, such as... Figure 1 and 10As shown in Figure -13, the telescopic clamping mechanism 5 clamps the end face of the bar material to achieve axial fixation. In the initial state, the telescopic frame 501 extends inward and is positioned within the folding block 406. The end face translation drive module 404 drives the mechanisms on both sides to clamp the bar material, preventing the bar material from shifting during the cylindrical packaging process and affecting the packaging effect. The end face translation slider module 403 is used to counteract unbalanced loads and protect the lead screw.

[0048] Step S5: Cylindrical packaging, such as Figure 5-8 As shown, the electric cylinder 304 synchronously drives the rocker arms 302 on both sides of the bar to rotate around the rocker arm hinge 311 until the rocker arms 302 press the steel plate firmly onto the bar, and the steel plate finally forms a U-shape, as shown. Figure 14 As shown in b. Under the action of the pressing surface spring 303, the adaptive pressing panel 301 is initially at its maximum angle with the swing rod 302. During the swing of the swing rod 302, the adaptive pressing panel 301 contacts the bar stock, and the angle between it and the swing rod 302 gradually decreases under the action of the bar stock, achieving an envelope wrapping effect and ensuring the quality of the steel plate packaging. After the swing rod electric cylinder 304 is loaded to the set force, it stops moving, and the two side closing electric cylinders 309 start working. The steel plate closing push block 306 presses the two free ends of the U-shaped steel plate onto the bar stock in sequence, first pressing the untreated end of the steel plate and then pressing the end with the bend, as shown in b. Figure 14 As shown in Figure c. For bars of different diameters, to ensure packaging effectiveness, the gap between the final positions of the two steel plate closing push blocks 306 should not be too large. The angle adjustment device 310 can be used to adjust the inclination angle of the closing structure, thus controlling the gap. Since the steel plate closing push block 306 is hinged to the working end of the closing electric cylinder 309, it can swing at a certain angle, ensuring that the tangent point between the working surface of the steel plate closing push block 306 and the cylindrical surface of the bar is at the center of the working surface of the steel plate closing push block 306, thus ensuring packaging effectiveness. The rubber block 313 ensures stable force transmission while allowing the steel plate closing push block 306 to rotate at a certain angle.

[0049] Step S6: Weld the cylindrical steel plates. A welding robot is used to weld the cylindrical steel plates. The end frames on both sides move outwards to release the bar stock. The pre-treated end-face steel plates are then placed on the end faces of the bar stock. (Example:...) Figure 15 As shown in Figure a, the end face steel plate is pre-treated into a six-petal shape, with a circular insulation cotton attached in the middle.

[0050] Step S7: End-face packaging, such as Figure 1 and 10 As shown in Figure -13, the end face translation drive module 404 synchronously drives the two end face frames to move towards the center. When the telescopic frame 501 presses the end face steel plate against the end face of the bar stock, the two end face frames continue to move towards the center. At the same time, the telescopic frame 501 moves outward relative to the end face frame, keeping the spatial position of the contact surface between the telescopic frame 501 and the steel plate unchanged, preventing the end face of the steel plate from bulging during end face packaging, which would affect the packaging quality. The initial state of the folding block 406 is as follows: Figure 12 As shown, the bar rises and gradually folds over upon contact with the steel plate, ultimately pressing the end face of the steel plate firmly against the bar stock surface, completing the end face packaging. The final packaging effect is as follows. Figure 15 As shown in b. The auxiliary pressure plate 405 remains in contact with the steel plate throughout the packaging process, ensuring that the steel plate is pressed firmly against the bar stock. This prevents bulging of the steel plate at the circumference of the bar stock when packaging small-diameter steel plates, which would affect the packaging quality.

[0051] Step S8: Welding the end face steel plate. The welding robot welds each steel plate segment onto the cylindrical steel plate, completing the end face packaging. Since the welding positions are evenly distributed across six points on a circumference, making welding inconvenient, the V-block 201 is lowered before welding. The bar stock is clamped only by the end face packaging mechanisms 4 on both sides, and can rotate under the drive of the end face rotation drive module 402, facilitating welding.

[0052] Step S9: Transfer the bar stock and restore the equipment to its initial state; the transfer robotic arm clamps the packaged bar stock, the two end frames move outward, and the telescopic frame 501 extends inward to transfer the bar stock; the folding block 406 and the auxiliary pressure plate 405 automatically return to their initial state under the action of the folding block spring 409 and the auxiliary pressure plate spring 407.
