Description

Technical Field

[0001] This invention relates to the field of casting technology, and in particular to a method and system for forming titanium alloy parts. Background Technology

[0002] Titanium alloys are high-temperature alloys. During the casting process of titanium alloy castings, a large number of pores appear inside the castings, which cannot be solved even by hot isostatic pressing. At the same time, when the castings solidify and shrink, the thick parts cannot be fed in time, forming large shrinkage cavities.

[0003] After casting, the risers and gating gates need to be cut and ground. To improve processing efficiency, cutting and grinding are usually done in one process. However, the transition between cutting and grinding may be interrupted or delayed due to various reasons, affecting processing efficiency, reducing production efficiency, and increasing processing cycle time. Because cutting and grinding chips are mixed in integrated cutting and grinding equipment, but their different forms increase the difficulty of sorting, recycling, and processing during post-processing cleaning and treatment due to differences in shape and material. Summary of the Invention

[0004] Based on the above analysis, the present invention aims to provide a method and system for forming titanium alloy parts, in order to solve the problems of low cutting and grinding efficiency of post-cast risers in titanium alloy casting and the difficulty in handling the mixture of chips and grinding shavings.

[0005] The objective of this invention is mainly achieved through the following technical solutions:

[0006] One aspect of the present invention provides a method for forming titanium alloy parts, comprising the following steps:

[0007] Step 1: Titanium alloy casting;

[0008] Step 2: Cutting and grinding the gating system of the titanium alloy casting;

[0009] Step 3: The titanium alloy casting is further machined and shaped.

[0010] Further, step 1 includes:

[0011] Step 1.1: The titanium alloy solution is poured from the crucible into the mold;

[0012] Step 1.2: Compact the unsolidified titanium alloy solution;

[0013] Step 1.3: Casting and shaping of titanium alloy parts.

[0014] Furthermore, in step 1.1, the vacuum consumable electrode solidification furnace has a rotating shaft, and the crucible is placed on the rotating shaft; in the first cycle, the rotating shaft rotates in the forward direction, causing the molten metal in the crucible to be poured into the mold; the rotating shaft rotates in the reverse direction, and the crucible is reset.

[0015] Further, the compaction conditions in step 1.2 are as follows: In the second cycle, compaction is performed using a casting auxiliary device. When the casting auxiliary device presses down, the temperature of the molten metal is 930℃-1750℃, and the pressure applied by the casting auxiliary device to the molten metal or the incompletely solidified casting is 45000Pa-90000Pa, with a holding time of 5min-7min.

[0016] Further, step 1.2 includes:

[0017] Step 1.2.1: The pressing rod of the casting auxiliary device moves to above the molten metal in the mold, and the rotating rod rotates until its end is below the end of the pressing rod;

[0018] Step 1.2.2: Rotate the lever upwards to push the end of the pressing lever upwards, and press the other end of the pressing lever downwards to press down the molten metal.

[0019] Furthermore, a rotating rod is radially arranged on the output shaft. The length direction of the rotating rod is perpendicular to the axis. The rotating rod pushes the pressure rod upward under the rotation of the output shaft.

[0020] Furthermore, step 2 specifically includes:

[0021] Step 2.1: Switching between gating and grinding operations for titanium alloy castings;

[0022] Step 2.2: Chips and grinding shavings are collected separately using a waste chip collection device.

[0023] Further, step 2.1 specifically includes:

[0024] Step 2.1.1: The tool assembly of the integrated cutting and grinding device is located at the cutting position to cut the gate and riser of the casting;

[0025] Step 2.1.2: The cutting tool of the tool assembly is retracted, and the tool assembly moves to the grinding station to grind the gating gate of the casting.

[0026] Furthermore, in step 2.2, the waste collection device includes a filter screen and a dust collection hopper arranged inclined along the length direction, as well as an impact structure and a tilting structure; the filter screen is vertically arranged on the upper part of the dust collection hopper, and the impact structure and the tilting structure are respectively arranged on both sides of the filter screen.

[0027] Furthermore, in step 2.2, the chips and grinding debris are sorted and collected by a waste chip collection device, specifically including:

[0028] Step 2.2.1: The chips remain on the filter screen, and the grinding debris is filtered into the dust collection hopper;

[0029] Step 2.2.2: After the grinding debris enters the dust collection hopper, it is collected by the dust collector;

[0030] Step 2.2.3: The impact structure impacts the filter screen, causing the chips inside the filter screen to descend along the inclined plane into the chip collection hopper; the chips that do not descend are poured into the collection hopper by the tilting structure.

[0031] Furthermore, in step 2.1.1, the cutting method of the cutting tool is as follows: the cam of the cam assembly in the integrated cutting and grinding device rotates, the arc contour of the cam presses down on the roller assembly, the roller assembly drives the tool assembly to descend, so that the cutting tool approaches the casting gating and riser.

[0032] Furthermore, the cutting tool adjustment structure is adjusted using a cutting tool to bring the cutting tool to the gating and riser of the casting for cutting.

[0033] Further, in step 2.1.2, the tool assembly moves to the grinding station, specifically including:

[0034] The cam profile disengages from the roller, the roller resets under the reset structure, and drives the tool assembly to reset. The roller assembly and the tool assembly move along the guide rail with the slider to the second limit block.

[0035] Furthermore, the cutting tool performs grinding on the gating and riser of the casting, specifically as follows:

[0036] The cam rotates, and its arc-shaped profile presses down on the roller assembly. The roller assembly drives the cutting tool downward, bringing the grinding tool close to the gating gate of the titanium alloy casting. The grinding tool adjustment mechanism is used to adjust the grinding tool downward to the gating gate of the titanium alloy casting for grinding.

[0037] Furthermore, in section 2.2.3, the manner in which the impact structure impacts the filter screen is as follows:

[0038] The first eccentric wheel of the impact structure rotates, one end of the first connecting rod slides in the groove of the eccentric wheel, and the second connecting rod connected to the other end of the first connecting rod slides back and forth in the straight rail, driving the impact hammer set at the front end of the second connecting rod to impact the filter screen, and the chips attached to the filter screen are peeled off after being impacted.

[0039] Furthermore, in section 2.2.3, the non-descending chips are poured into the collection hopper via a tilting structure, specifically as follows:

[0040] The tilting structure rotates through the rotation of the second eccentric wheel, which drives the L-shaped rod to rotate. The third connecting rod, which is fixed at the other end of the L-shaped rod, drives the swing rod to swing. When one end of the L-shaped rod that is fixed in the groove of the second eccentric wheel rises to the highest point in the groove of the second eccentric wheel, the third connecting rod drives the swing rod to swing to the lowest position at the upper end of the swing rod. At this time, the remaining chips in the filter screen are tilted and poured into the chip collection hopper.

[0041] In another aspect, the present invention provides a titanium alloy part forming system for implementing the aforementioned titanium alloy part forming method.

[0042] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0043] (1) Compared with the prior art, in the titanium alloy casting process, after pouring the molten metal, the present invention uses the rotating shaft of the vacuum consumable electrode solidification furnace to drive the gear system to rotate, and the rack drives the entire mechanism to slide on the track. After the pressure head of the pressure rod is aligned with the molten metal in the mold, the lever principle is used to rotate the rod to push the first end of the pressure rod upward and the second end downward to press down the unsolidified molten metal, thereby compacting the porosity and shrinkage defects. The present invention combines the gear and rack structure and the lever principle, which is simple, precise and efficient. At the same time, it can increase the filling force of high-temperature alloy casting, reduce the forming limit of thin-walled parts, save energy and reduce emissions, and is easy to operate.

[0044] (2) Compared with the prior art, the present invention utilizes the precise and controllable contour curve of the cam in the cutting machine to control the cutting or grinding process. The cam and roller work together to switch between cutting and grinding efficiently through the pulley and slider. By setting the adjustment structure for cutting or grinding, the switching method of cutting and grinding is applicable to the processing of casting risers of different heights.

[0045] (3) Compared with the prior art, this invention classifies and collects waste chips and grinding shavings according to their morphology using a waste chip collection device. A filter screen is used to collect the chips, and a dust collection hopper is used to collect the grinding shavings. Since the chips are thin and filamentous, they easily adhere to the filter screen. An impact structure is used to detach the chips from the filter screen and allow them to enter the dust collection hopper. For any remaining chips, a tilting structure is used to pour them into the dust collection hopper. This solves the problem of chip mixing and accumulation in integrated cutting and grinding processes, and can efficiently handle both cutting and grinding chips.

[0046] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the specification or be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained from the content specifically pointed out in the text and accompanying drawings. Attached Figure Description

Detailed Implementation

[0057] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which 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 intended to limit the scope of the present invention.

[0058] Example 1

[0059] A specific embodiment of the present invention, such as Figure 1 As shown, a method for forming titanium alloy parts is disclosed, including the following steps:

[0060] Step 1: Titanium alloy casting;

[0061] Step 2: Cutting and grinding the gating system of the titanium alloy casting;

[0062] Step 3: The titanium alloy casting is further machined and shaped.

[0063] In step 1, the titanium alloy casting process includes:

[0064] Step 1.1: The titanium alloy solution is poured from the crucible into the mold;

[0065] Step 1.2: Compact the unsolidified titanium alloy solution;

[0066] Step 1.3: Casting and shaping of titanium alloy parts.

[0067] In step 1.1, the titanium alloy solution is poured into a mold from the crucible of the vacuum consumable electrode solidification furnace 1. Specifically, the vacuum consumable electrode solidification furnace 1 has a rotating shaft 11, and the crucible is mounted on the rotating shaft 11.

[0068] The titanium alloy solution is poured from the crucible into the mold in the following manner: In the first cycle, the rotating shaft 11 rotates in the forward direction, causing the molten metal in the crucible to pour into the mold; the rotating shaft 11 rotates in the reverse direction, and the crucible is reset.

[0069] In step 1.2, the compaction method is as follows:

[0070] Step 1.2.1: The pressing rod 25 of the casting auxiliary device moves to above the molten metal in the mold, and the rotating rod 24 rotates until its end is below the end of the pressing rod 25.

[0071] Step 1.2.2: Rotate rod 24 to push the end of pressing rod 25 upward, and press the other end of pressing rod 25 down to press the molten metal.

[0072] In step 1.2.1, during the second cycle, the rotating shaft 11 rotates in the forward direction. The gear system 22 on the rotating shaft 11 is provided with a rack 23 at the lower part. The gear system 22 rolls on the rack 23 until it reaches the pressure rod 25 located at the other end of the rack 23.

[0073] It should be noted that the gear train 22 has an output shaft 221, and a ratchet 26 and a pawl are provided in the gear train 22. In the first cycle, when the rotating shaft 11 rotates in reverse, the crucible resets, the pawl slides on the back of the teeth of the ratchet 26, preventing the ratchet 26 from continuing to rotate, and the gear train 22 and the output shaft 221 also stop rotating. In the second cycle, when the rotating shaft 11 rotates in the forward direction, the ratchet 26 and the pawl rotate normally, and the gear train 22 and the output shaft 221 rotate normally.

[0074] Furthermore, the lower part of the auxiliary device is provided with a support structure 21, which is set on the track. The rack 23 is set on the support structure 21, and the rotation of the gear train 22 on the rack 23 enables the entire auxiliary device to slide on the track.

[0075] In step 1.2.2, specifically, a rotating rod 24 is radially arranged on the output shaft 221. The length direction of the rotating rod 24 is perpendicular to the axis. Under the rotation of the output shaft 221, the rotating rod 24 pushes the pressure rod 25 upward, so that the end of the pressure rod 25 near the rotating rod 24 is lifted upward, thereby pressing the end of the pressure rod 25 away from the rotating rod 24 with the pressure head 252 downward to press the unsolidified molten metal.

[0076] It should be noted that the compaction conditions are as follows: the temperature of the molten metal is 930℃-1750℃ when the casting auxiliary device 2 presses down, the pressure applied by the auxiliary device to the molten metal or the incompletely solidified casting is 45000Pa-90000Pa, and the pressure holding time is 5min-7min.

[0077] Compared to existing technologies, in this embodiment, after the molten metal is poured during casting, the rotating shaft 11 of the vacuum consumable electrode solidification furnace 1 drives the gear train 22 to rotate. After the pressure head 252 of the pressing rod 25 is aligned with the molten metal in the mold, the rack 23 drives the entire mechanism to slide on the track. After the pressure head 252 of the pressing rod 25 is aligned with the molten metal in the mold, the rotating rod 24 uses the lever principle to push the first end of the pressing rod 25 upward and the second end downward to press down the unsolidified molten metal, thereby compacting porosity and shrinkage defects. This embodiment combines the gear and rack 23 structure with the lever principle, resulting in a simple, precise, and efficient structure. At the same time, it can increase the filling force of high-temperature alloy casting, thereby reducing the forming limit of thin-walled parts.

[0078] Step 2 specifically includes:

[0079] Step 2.1: Cutting and grinding the gating system of titanium alloy castings;

[0080] Step 2.2: Chips and grinding shavings are collected separately by the waste chip collection device 4.

[0081] In step 2.1, in order to improve the processing efficiency of the gating and riser, the gating and riser of the titanium alloy casting is cut and ground by an integrated cutting and grinding device 3.

[0082] Step 2.1 specifically includes:

[0083] Step 2.1.1: The tool assembly 34 of the integrated cutting and grinding device 3 is located at the cutting position to cut the gating and riser of the casting;

[0084] Step 2.1.2: The cutting tool of the tool assembly 34 is retracted, and the tool assembly 34 moves to the grinding station to grind the gating gate of the casting.

[0085] In step 2.1.1, the cutting method of the cutting tool is as follows: the cam rotates, and the arc contour of the cam presses down on the roller assembly 3232. The roller assembly 3232 drives the tool assembly 34 to descend, so that the cutting tool 341 approaches the casting gating and riser. The cutting tool adjustment structure is used to adjust the cutting tool 341 to descend to the casting gating and riser, and to perform cutting processing of the titanium alloy gating and riser.

[0086] It is important to note that the cam has a circular arc profile. The central angle of the cam's arc corresponds to the cam's rotational speed and the duration of cutting and grinding. When the cam initially contacts the roller 321 along the arc, it presses down on the roller 321 to perform cutting or grinding. When the cam rotates to the end of the arc, the cutting or grinding is completed.

[0087] In step 2.1.2, the tool assembly 34 moves to the grinding station, specifically including:

[0088] The cam profile disengages from roller 321, and roller 321 resets under roller reset structure 322, driving tool assembly 34 to reset. Roller assembly 3232 and tool assembly 34 move along the guide rail with slider 332 to the second limit block.

[0089] The cutting tool performs grinding on the gating and riser of the casting, specifically as follows:

[0090] The cam rotates, and the arc profile of the cam presses down on the roller assembly 3232. The roller assembly 3232 drives the cutting tool to descend, bringing the grinding tool 341 close to the casting gate and riser. The grinding tool adjustment structure is used to adjust the grinding tool to descend to the casting gate and riser for grinding.

[0091] Compared with the prior art, this embodiment utilizes the precise and controllable contour curve of the cam in the integrated cutting machine to control the cutting or grinding process. The cam and roller 321 work together to switch between cutting and grinding efficiently through the pulley slider 332. By setting the adjustment structure for cutting or grinding, the switching method of cutting and grinding is applicable to the processing of casting risers and gating gates of different heights.

[0092] In step 2.2, the chips and grinding waste are collected separately by the waste chip collection device 4, specifically including:

[0093] Step 2.2.1: The chips remain on the filter screen 41, and the grinding chips are filtered into the dust collection hopper 42.

[0094] Step 2.2.2: After the grinding debris enters the dust collection hopper 42, it is collected by the dust collector.

[0095] Step 2.2.3: The impact structure 411 impacts the filter screen 41, causing the chips inside the filter screen 41 to descend along the inclined surface into the chip collection hopper; the chips that do not descend are poured into the collection hopper by the tilting structure 412.

[0096] To accommodate different types of chips and grinding shavings—long, thin chips and small grinding shavings—a waste chip collection structure is installed at the lower part of the workstation of the integrated cutting and grinding device 3. The waste chip collection device 4 includes an inclined filter screen 41 and a dust collection hopper 42. The filter screen 41 is vertically positioned above the dust collection hopper 42. The filter screen 41 filters the chips, and the dust collection hopper 42 collects the grinding shavings.

[0097] In step 2.2.1, the waste chips fall to the waste chip collection structure, the filter screen 41 intercepts the chips, and the grinding chips are filtered into the dust collection hopper 42.

[0098] In step 2.2.3, because the chips are thin and filamentous, they easily adhere to the filter screen 41 and are not easy to slide down the inclined surface. An impact structure 411 is provided on one side of the filter screen 41 to knock off the chips attached to the filter screen 41 and slide them into the chip collection hopper.

[0099] Specifically, the first eccentric wheel 4111 rotates, and one end of the first connecting rod 4112 slides in the groove of the eccentric wheel, causing the second connecting rod 4114, which is connected to the other end of the first connecting rod 4112, to slide back and forth in the straight rail 4113. This causes the impact hammer 4115, which is located at the front end of the second connecting rod 4114, to impact the filter screen 41, causing the chips attached to the filter screen 41 to peel off after the impact. It should be noted that a second return spring is provided between the impact hammer 4115 and the second connecting rod 4114, so that the impact hammer 4115 returns to its original position immediately after the impact.

[0100] The tilting structure 412 in step 2.2.3 is located on the other side of the filter screen 41. The rotation of the second eccentric wheel 4121 drives the L-shaped rod 4122 to rotate. Utilizing the lever effect, the third connecting rod 4123, which is fixed at the other end of the L-shaped rod 4122, drives the swing rod 4124 to swing. When one end of the L-shaped rod 4122 reaches the highest point in the groove of the second eccentric wheel 4121, the third connecting rod 4123 drives the swing rod 4124 to swing until the end of the swing rod 4124 is at the lowest position. At this time, the remaining chips in the filter screen 41 are poured into the chip collection hopper.

[0101] Compared to existing technologies, this embodiment classifies and collects waste chips and grinding shavings based on their morphology using a waste chip collection device 4. A filter screen 41 collects the chips, and a dust collection hopper 42 collects the grinding shavings. Since the chips are thin and filamentous, they easily adhere to the filter screen 41. An impact structure 411 is used to detach the chips from the filter screen 41 and allow them to enter the dust collection hopper. For any remaining chips, a tilting structure 412 is used to pour them into the dust collection hopper. This solves the problem of chip mixing and accumulation in integrated cutting and grinding processes, and enables efficient handling of cutting and grinding chips.

[0102] Example 2

[0103] This embodiment discloses a titanium alloy part forming system for implementing the titanium alloy part forming method of Embodiment 1, such as... Figures 2-7 As shown, it includes casting equipment, casting auxiliary device 2, integrated cutting and grinding device 3, and waste chip collection device 4.

[0104] like Figure 2 As shown, the casting equipment includes a vacuum consumable electrode solidification furnace 1 and a crucible. The vacuum consumable electrode solidification furnace 1 has a rotating shaft 11, and the crucible is mounted on the rotating shaft 11. During the first cycle, when the rotating shaft 11 rotates in the forward direction, the molten metal in the crucible is poured into the mold for casting. When the rotating shaft 11 rotates in the reverse direction, the crucible is reset.

[0105] like Figure 3 As shown, the casting auxiliary device 2 includes a support structure 21, a gear train 22, a rack 23, a rotating rod 24, and a pressure rod 25.

[0106] Gear train 22, rack 23, rotating rod 24, and pressure rod 25 are mounted on support structure 21. Support structure 21 is mounted on the lower track, and rack 23 is mounted on support structure 21. Gear train 22 and pressure rod 25 are respectively located at the upper ends of rack 23. Rotation of gear train 22 on rack 23 allows the entire auxiliary device to slide on the track.

[0107] The gear train 22 is equipped with a ratchet 26 and a pawl. In the first cycle, when the rotating shaft 11 reverses direction, the crucible resets, and the pawl slides on the back of the teeth of the ratchet 26, preventing the ratchet 26 from continuing to rotate. In the second cycle, when the rotating shaft 11 rotates in the forward direction, the ratchet 26 and the pawl rotate normally.

[0108] The gear train 22 has an output shaft 221, on which a rotating rod 24 is radially arranged, the length direction of which is perpendicular to the axis. A pressure rod 25 is hinged to a rack 23; one end of the pressure rod 25 is provided with a compression spring 251, and the other end is provided with a pressure head 252, with a first return spring 253 provided near the pressure head 252. When the rotating rod 24 rotates on the output shaft 221, the end of the rotating rod 24 is below the end of the pressure rod 25's compression spring 251. As the output shaft 221 rotates, the rotating rod 24 pushes the pressure rod 25 upwards, causing the pressure head 252 of the pressure rod 25 to press down on the unsolidified molten metal.

[0109] like Figure 4 As shown, the integrated cutting and grinding device 3 includes a cam assembly 31, a roller assembly 3232, a slide rail assembly 33, and a cutter assembly 34. The roller assembly 3232 is located at the lower part of the cam assembly 31, and the cutter assembly 34 is located at the lower end of the roller assembly 3232 and connected to the roller assembly 3232.

[0110] The cam assembly 31 includes two cams, the roller assembly 3232 includes a roller 321 and a roller reset structure 322, and the tool assembly 34 includes a tool and a tool adjustment structure.

[0111] The cam has a circular arc profile. The central angle of the cam's arc corresponds to the cam's rotational speed and the duration of cutting and grinding. When the cam contacts the roller 321 from the beginning of the arc, it presses down on the roller 321 to perform cutting or grinding. When the cam rotates to the end of the arc, the cutting or grinding is completed.

[0112] To accommodate risers and gating gates of varying heights, a tool adjustment mechanism is provided, which includes an adjustment motor and guide pillars. Cutting tool 341 and grinding tool 342 are respectively positioned at both ends of the tool holder. When cutting, the cutting tool 341 is raised or lowered to the riser / gating gate position via the tool adjustment mechanism, moving the fixed plate accordingly. Similarly, when grinding, the grinding tool 342 is raised or lowered to the riser / gating gate position via the grinding tool adjustment mechanism, moving the fixed plate accordingly.

[0113] The slide rail 331 structure includes a slide rail 331 and a slider 332, and a roller reset structure 322 is disposed on the slider 332. A first limit block and a second limit block are provided at both ends of the slide rail 331 for limiting the slider 332.

[0114] like Figure 5 As shown, the waste chip collection device 4 includes an inclined filter screen 41 and a dust collection hopper 42. The filter screen 41 is vertically arranged on the upper part of the dust collection hopper 42. The filter screen 41 is used to filter chips, and the dust collection hopper 42 is used to collect grinding chips.

[0115] like Figure 6As shown, an impact structure 411 is provided on one side of the filter screen 41 to knock off the chips attached to the filter screen 41 and slide them into the chip collection hopper. The impact structure 411 includes a first eccentric wheel 4111, a first connecting rod 4112, a straight rail 4113, an impact hammer 4115, and a second return spring.

[0116] The first connecting rod 4112 is disposed in the groove of the first eccentric wheel 4111, and the end of the second connecting rod 4114 is connected to the end of the first connecting rod 4112. The second connecting rod 4114 can slide in the straight rail 4113. The impact hammer 4115 is disposed at the other end of the second connecting rod 4114, and a second return spring is disposed between the second connecting rod 4114 and the impact hammer 4115.

[0117] like Figure 7 As shown, a tilting structure 412 is provided on the other side of the filter screen 41. The tilting structure 412 includes a second eccentric wheel 4121, an L-shaped rod 4122, a third connecting rod 4123, and a swing rod 4124. One end of the L-shaped rod 4122 is disposed in the groove of the second eccentric wheel 4121, and the other end is connected to the third connecting rod 4123, with the middle part hinged to a fixed plate. The third connecting rod 4123 is disposed in the middle of the swing rod 4124, and the end of the swing rod 4124 is fixedly connected to one side of the filter screen 41.

[0118] The second eccentric wheel 4121 rotates, driving the L-shaped rod 4122 to rotate. Utilizing the lever effect, the third connecting rod 4123, which is fixed at the other end of the L-shaped rod 4122, drives the swing rod 4124 to swing. When one end of the L-shaped rod 4122 reaches the highest point in the groove of the second eccentric wheel 4121, the third connecting rod 4123 drives the swing rod 4124 to swing until the end of the swing rod 4124 is at the lowest position. At this time, the remaining chips in the filter screen 41 are poured into the chip collection hopper.
