DETAILED DESCRIPTION

[0035] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0036] A specific embodiment of the present invention, as Figure 1-Figure 3 As shown, a high-temperature alloy part forming and post-processing device is disclosed, including an auxiliary forming component 1 and a post-processing component 2. The auxiliary forming component 1 is used for auxiliary pressing during high-temperature alloy forming, and the post-processing component 2 is used for processing and processing the high-temperature alloy after forming and waste processing.

[0037] The high-temperature alloy forming and post-processing device of this embodiment includes an auxiliary forming component 1 and a post-processing component 2; the auxiliary forming component 1 is used for auxiliary pressing during the forming of the high-temperature alloy, and the post-processing component 2 is used for processing and forming the high-temperature alloy after forming and waste processing to achieve the forming of high-temperature alloy parts.

[0038] like Figure 1 As shown, the auxiliary molding assembly 1 includes a gear rack structure 11, a pressing structure 12 and a supporting structure 13. The supporting structure 13 is used to support the gear rack structure 11 and the pressing structure 12.

[0039] To ensure stable operation of the entire structure and precise transmission of the pressing structure 12, this embodiment uses a rack and pinion structure 11 for transmission. The rack and pinion structure 11 includes a first rotating shaft 111, a second rotating shaft 112, a gear train 113, and a rack 114. The first rotating shaft 111 is the input shaft of the gear train 113, providing power to the rack and pinion structure 11; the second rotating shaft 112 is the gear output shaft, providing power to the pressing structure 12.

[0040] Gear train 113 includes multiple gears: a first gear 1131, a second gear 1132, a third gear 1133, and a fourth gear 1134. Second gear 1132 is mounted on first gear 1131 and third gear 1133, meshing with these gears, respectively. Specifically, first gear 1131 is mounted on first shaft 111, while third gear 1133 and fourth gear 1134 are mounted on second shaft 112.

[0041] Furthermore, a rack 114 is provided at the lower portion of the fourth gear 1134 , and the fourth gear 1134 can roll on the rack 114 under the drive of the second rotating shaft 112 .

[0042] It should be noted that, in order to improve transmission efficiency, the diameters of the first gear 1131 , the third gear 1133 , and the fourth gear 1134 are the same, and the total meshing ratio of the gears is 1:1.

[0043] The pressing structure 12 includes a rotating rod 121 and a pressing rod 122 . The rotating rod 121 is rotated to push the pressing rod 122 upward, so that the pressing rod 122 can press the molten metal.

[0044] The pressing rod 122 is arranged at the end of the rack 114 away from the fourth gear 1134, and is hinged to the rack 114 to form a lever structure with the rack 114 as the fulcrum. The pressing rod 122 has a first end and a second end. The first end is provided with a first spring 1221. Specifically, the first spring 1221 is arranged perpendicular to the axis of the pressing rod 122. When the rotating rod 121 pushes the pressing rod 122 upward, the first spring 1221 can buffer the upward force. The second end is provided with a pressure head 1222. When the first end is tilted, the pressure head 1222 can press the unsolidified molten metal. The pressure head 1222 is disc-shaped and made of graphite, which can increase the contact area with the molten metal.

[0045] Furthermore, a second spring 1223 is disposed near the second end of the pressing rod 122. One end of the second spring 1223 is connected to the pressing rod 122, and the other end is connected to the support structure 13. The second spring 1223 is oriented perpendicular to the axis of the pressing rod 122 and serves to reset the pressing rod 122. When the rotating rod 121 leaves the pressing rod 122, the second spring 1223 causes the second end of the pressing rod 122 to move upward, returning to its original position.

[0046] The rotating rod 121 is mounted on the second rotating shaft 112, with its length perpendicular to the central axis of the second rotating shaft 112. The rotating rod 121 rotates along with the second rotating shaft 112. When the rotating rod 121 rotates below the pressing rod 122, the end of the rotating rod 121 aligns with the first end of the pressing rod 122. The rotating rod 121 pushes the first spring 1221 upward, thereby lifting the first end of the pressing rod 122 and pressing the second end downward.

[0047] The position of the first spring 1221 corresponds to the position of the end of the rotating rod 121 rotated to the bottom of the rotating rod 121. When the end of the rotating rod 121 rotates to the bottom of the first spring 1221, it contacts the first spring 1221. The rotating rod 121 continues to rotate, compressing the first spring 1221 upward, and causing the first end of the pressing rod 122 to rise. Under the action of the lever, the end of the second end descends, causing the pressure head 1222 to contact and press the mold and the molten metal. The pressure head 1222 moves downward to apply pressure to the unsolidified molten metal, promoting the flow of molten metal during the casting process. The rotating rod 121 continues to rotate and leaves the first spring 1221. Under the reset action of the second spring 1223, the pressure head 1222 leaves the pouring cup mouth.

[0048] The support structure 13 is used to support the rack and pinion structure and the pressing structure 12 , and includes a support frame 131 and a track 132 . The support frame 131 is movable on the track 132 .

[0049] Support frame 131 includes multiple columns. A slider is mounted at the bottom of the frame and is mounted on a track 132, allowing it to slide within the track. A pressing structure 12 and a rack-and-pinion structure 11 are mounted on support frame 131, with a rack 114 positioned at its upper end. The pressing structure 12 and gear train 113 are capable of moving along the rack 114, driving the pressing structure 12, rack-and-pinion structure 11, and support frame 131 along the track 132. This allows the pressing structure 12 to repeatedly compact the molten metal in the casting.

[0050] During use, the first rotating shaft 111 rotates in the forward direction, driving the gear train 113 to rotate. The fourth gear 1134 rolls on the rack 114, driving the entire mechanism to slide on the track 132 of the support structure 13, until the pressure head 1222 is aligned with the beaker and stops. The first rotating shaft 111 rotates in the reverse direction, and the rotating rod 121 rotates, with its end located at the first end of the pressing rod 122. The rotating rod 121 squeezes the first spring 1221, causing the first end to move upward, and under the action of the lever, the second end presses down on the unsolidified molten metal in the mold to promote the flow of the molten metal. The rotating rod 121 continues to rotate and leaves the first spring 1221. The pressing rod 122, under the action of the second spring 1223, causes the pressure head 1222 to leave the pouring cup mouth.

[0051] Compared to the prior art, in this embodiment, rack 114 drives the entire mechanism to slide on track 132. After the pressure head 1222 of pressing rod 122 is aligned with the molten metal in the mold, lever 121 is used to move the first end of pressing rod 122 upward and the second end downward to press down on the unsolidified molten metal, thereby compacting air holes and shrinkage defects. This embodiment combines the rack and pinion structure 11 with the principle of leverage, resulting in a simple structure, precise and efficient operation, while also increasing the filling force of high-temperature alloy castings and reducing the forming limit of thin-walled parts.

[0052] like Figure 2 As shown, the post-processing assembly 2 includes a tool switching structure 21. The tool switching structure 21 includes a cam 211, a roller 212 and a tool 213.

[0053] There are two cams 211, which are arranged opposite to each other, corresponding to the cutting station and grinding station of the tool 213. Specifically, the profile of the cam 211 is a 1 / 4 arc line. The cam 211 has a cam 211 motor, which drives the cam 211 to rotate.

[0054] The roller 212 is disposed below the cam 211. The roller 212 has a roller reset structure 2121 for resetting the roller 212 after the contour line of the cam 211 is separated from the roller 212.

[0055] The upper end of roller reset structure 2121 is fixed to roller 212. Roller reset structure 2121 includes a guide post, a linear bearing, and a third spring. The guide post and the third spring are connected, and the guide post can drive roller reset structure 2121 in vertical linear motion. The third spring is used to reset roller 212.

[0056] The cutter 213 is arranged on a cutter frame 213. The cutter frame 213 is connected to the roller reset structure 2121 and is arranged at the lower part of the roller reset structure 2121. When the cam 211 presses the roller 212 downward, the cutter 213 performs cutting or grinding.

[0057] The tool 213 includes a cutting tool 2131 and a grinding tool 2132 respectively arranged at both ends of the tool frame 213. The upper parts of the cutting tool 2131 and the grinding tool 2132 are connected with a fixing block.

[0058] To accommodate casting risers of varying heights, cutting tool 2131 and grinding tool 2132 are equipped with cutting tool adjustment mechanisms and grinding tool adjustment mechanisms, respectively. These mechanisms include guide posts equipped with motors. Driven by these motors, the fixed block of tool 213 raises and lowers tool 213. When cutting tool 2131 is in use, it descends to perform cutting; when grinding tool 2132 is in use, it descends to perform grinding.

[0059] Furthermore, the central angle of the arc of the cam 211 corresponds to the rotation speed of the cam 211 and the duration of the cutting or grinding process. When the cam 211 contacts the roller 212 at the start of the arc, the roller 212 is pressed down to perform cutting or grinding. When the cam 211 rotates to the end of the arc, the cutting or grinding process is completed.

[0060] The tool 213 switching structure 21 further includes a slide rail and a slider. The slider is arranged on the slide rail, and the roller reset structure 2121 is arranged on the slider. The roller reset structure 2121 can move along the slide rail with the slider to switch the cutting station and the grinding station.

[0061] Furthermore, a first limit block and a second limit block are provided at both ends of the slide rail for limiting the movement of the slider, wherein the first limit block corresponds to the cutting station and the second limit block corresponds to the grinding station.

[0062] During use, the cam 211 rotates, pressing down the roller 212 and the roller reset mechanism 2121. The roller reset mechanism 2121 causes the cutter 213 to descend, and the cutting tool 2131, under the control of the cutting tool adjustment mechanism, extends to cut the workpiece. After cutting, the cam 211 moves away from the roller 212, the roller reset mechanism 2121 causes the cutter 213 to reset, and the cutting tool adjustment mechanism causes the cutting tool 2131 to rise and leave the workpiece.

[0063] Under the action of the slider, roller 212 begins to move along the guide rail from the first stop until it stops at the second stop. Cam 211 then rotates, pressing down roller 212 and roller reset mechanism 2121. Roller reset mechanism 2121 lowers tool holder 213, and grinding tool 2132, controlled by the cutting tool 2131 adjustment mechanism, extends to grind the workpiece. After grinding, cam 211 moves away from roller 212, roller reset mechanism 2121 resets tool 213, and tool 213 adjustment mechanism raises grinding tool 2132 away from the workpiece.

[0064] The roller 212 moves toward the cutting station and stops at the first limit block.

[0065] Compared to existing technologies, this embodiment incorporates a tool 213 switching mechanism 21, which includes a cam 211, a roller 212, a tool 213, a slider, and a slide rail. The slider and slide rail drive the roller reset mechanism 2121 and the tool 213 to the cutting or grinding station. Cutting or grinding is performed using the profile curve of the cam 211, ensuring accurate delivery of the tool 213 to the cutting or grinding station and rapid switching between cutting and grinding operations. This ensures precise control, stability, reliability, and efficiency.

[0066] like Figure 3 As shown, the post-processing component 2 also includes a waste chip recovery structure 22. Since the shapes of cutting chips and grinding chips are different, cutting chips are slender and large, while grinding chips are small particles. According to different waste chips, a waste chip recovery structure 22 is provided, including a filter 221 and a dust hopper 222. In order to facilitate collection, the filter 221 and the dust hopper 222 are both tilted, and the filter 221 is vertically arranged on the upper part of the dust hopper 222. The filter 221 is used to filter cutting chips, and the dust hopper 222 is used to collect grinding chips. When the waste chips fall from the work station, the filter 221 filters out the smaller grinding chips, leaving the slender cutting chips, and the cutting chips and grinding chips in the waste chips are separated.

[0067] In this embodiment, the waste chip recovery structure 22 adopts a filter 221 structure to process the cutting chips and grinding chips separately according to the difference between cutting chips and grinding chips. The cutting chips are slender and large, while the grinding chips are small. The waste chips are filtered out by the filter 221, and the grinding chips with small particles fall directly into the dust collecting hopper 222 at the bottom of the filter 221 for collection, which solves the problem of debris mixing and accumulation in the integrated cutting and grinding processing, and can efficiently process cutting chips and grinding chips.

[0068] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
