Description

Technical Field

[0001] This invention belongs to the field of casting gate trimming technology, and in particular relates to a trimming device for metal casting. Background Technology

[0002] After casting, metal castings generally need to undergo gate removal. For ductile iron castings, the existing technologies for gate removal mainly include hydraulic separators, cutting, and manual hammering. In order to reduce labor costs and improve production efficiency, some companies use automatic gate removal equipment.

[0003] A Chinese patent with publication number CN117123768B discloses a metal casting gate trimming device, including a trimming table for removing the gate of the casting. Mounting plates are fixedly installed on both sides of the trimming table, and a conveyor belt for conveying the casting is installed inside the mounting plates. A hydraulic rod is fixedly installed on the trimming table, and a pushing mechanism for removing the gate of the casting is provided above the conveyor belt. The pushing mechanism is fixedly connected to the lower end of the hydraulic rod. A positioning mechanism for fixing the casting is slidably connected to one side of the trimming table. The positioning mechanism is connected to the pushing mechanism. This invention incorporates a pushing mechanism, which includes a connecting rod located at the lower end of a T-shaped rod, and a push ring at the lower end of the connecting rod.

[0004] When the above-mentioned casting gate trimming device is working, the castings on the conveyor belt can achieve position correction when passing through the guide block. When the castings reach the bottom of the push ring, they must meet the concentric position requirement in order to remove the gate. However, the castings passing through the guide block are easily affected by the vibration during the transmission process before reaching the push ring, which causes them to become misaligned. This makes it impossible for the push ring to be accurately fitted onto the castings to remove the gate. At the same time, the above-mentioned casting gate trimming device cannot complete the continued conveying of the castings after the gate treatment by the same set of transmission systems. Summary of the Invention

[0005] The purpose of this invention is to provide a finishing device for metal casting. Through the specific structural design of the casting conveying mechanism, steering power mechanism, finishing component, limiting part, transmission component and pushing component, it solves the problems of existing casting gate finishing devices, which cannot achieve precise fitting of the push ring onto the casting to remove the gate, and cannot continue to convey the casting after the gate treatment by the same set of transmission system.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: The present invention is a dressing device for metal casting, including a casting conveying mechanism, wherein the casting conveying mechanism includes a casting conveyor belt, and a conveyor belt support platform is provided on the inner side of the casting conveyor belt; an X-axis guide rail and a Y-axis guide rail connected to each other are installed on the top of the conveyor belt support platform, and an arc-shaped return seat for docking with the casting conveyor belt is connected to one side of the Y-axis guide rail; a steering power mechanism is rotatably arranged above the casting conveyor belt, and a dressing mechanism is slidably arranged at the bottom of the steering power mechanism; the steering power mechanism includes a steering screw threadedly connected to the dressing mechanism, and the X-axis guide rail... The intersection of the Y-axis guide rail and the arc-shaped return seat forms a turning point one, and the intersection of the Y-axis guide rail and the arc-shaped return seat forms a turning point two. The steering screw is used to control the reciprocating motion of the dressing mechanism between turning point one and turning point two. The dressing mechanism includes two symmetrically arranged Y-axis push plates, with a concentric dressing component between the Y-axis push plates. The casting conveyor belt is used to transport the metal casting to turning point one, and the Y-axis push plates are used to transport the metal casting to turning point two. The concentric dressing component removes the circumferential gate of the metal casting through lifting and lowering movement. The steering power mechanism rotates 90° to transport the dressed metal casting along the arc-shaped return seat onto the casting conveyor belt.

[0007] In this embodiment of the invention, the casting conveying mechanism further includes a support frame for mounting the conveyor belt support platform. A Y-axis support seat is fixedly provided on the side of the conveyor belt support platform near the Y-axis guide rail. A discharge motor is installed on one side of the Y-axis support seat. The output end of the discharge motor is connected to a discharge screw. The bottom of the X-axis guide rail is attached to the top of the casting conveyor belt. The bottom of the Y-axis guide rail is attached to the top of the Y-axis support seat. The bottom of the arc-shaped return seat is attached to the top of the conveyor belt support platform.

[0008] In this embodiment of the invention, the X-axis guide rail is composed of an X-axis alignment port and an X-axis guide cavity, and the Y-axis guide rail is composed of a Y-axis alignment port and a Y-axis guide cavity. The X-axis guide cavity and the Y-axis guide cavity are connected through the Y-axis alignment port. One end of the arc-shaped return seat is attached to the casting conveyor belt, and the other end of the arc-shaped return seat is connected to the Y-axis guide cavity. A scraper plate located at the end of the Y-axis guide rail is fixed on the top of the Y-axis support seat.

[0009] In this embodiment of the invention, an L-shaped support seat is slidably arranged inside the Y-axis support seat. The top surface of the L-shaped support seat, the top surface of the casting conveyor belt, and the inner bottom surface of the arc-shaped return seat are flush with each other. An internally threaded tube sleeved on the unloading screw is fixed on one side of the L-shaped support seat, and the internally threaded tube is threadedly connected to the unloading screw.

[0010] In this embodiment of the invention, the steering power mechanism further includes a rotary mounting bracket, a bearing plate coaxial with the bottom of the rotary mounting bracket, a horizontal extension platform fixed on the periphery of the bearing plate, a radial channel provided between the horizontal extension platform and the bearing plate, a guide shaft fixed on one side of the radial channel, and a steering screw rotatably provided on the other side of the radial channel. A steering motor mounted on the motor mount on the top of the bearing plate is connected to the steering screw.

[0011] In this embodiment of the invention, the trimming mechanism includes a trimming component; wherein, the trimming component includes a movable carrier plate that slides against the bottom of the support plate, a connecting seat that slides with the radial channel is fixed on the top of the movable carrier plate, the connecting seat is sleeved between the guide shaft and the steering screw, and the steering screw is threadedly connected to the connecting seat, a trimming cylinder located inside the radial channel is installed on the top of the movable carrier plate, and a concentric trimming component is connected to the output shaft of the trimming cylinder.

[0012] In this embodiment of the invention, two sets of mounting seats are symmetrically fixed at the bottom of the movable carrier plate, and a vertical guide seat is fixed on one side of each set of mounting seats. A limit part is slidably provided inside the vertical guide seat. A lifting frame is fixedly installed on the output shaft of the trimming cylinder, and vertical toothed plates are fixed on opposite sides of the lifting frame.

[0013] In this embodiment of the invention, the trimming mechanism further includes a transmission assembly; wherein, the transmission assembly includes a rotating cylinder disposed below the movable carrier plate, a support shaft coaxial with the rotating cylinder is provided on the inner side of the rotating cylinder, each set of mounting seats is rotatably connected to the corresponding support shaft, the rotating cylinder and the support shaft are connected by a fastener, a transmission gear meshing with a vertical toothed plate is fixedly installed at the end of the support shaft, and a connecting sleeve is fixedly installed on the inner wall of the rotating cylinder.

[0014] In this embodiment of the invention, the trimming mechanism further includes a pushing component; wherein, the pushing component includes a Y-axis pushing plate, two L-shaped support members are symmetrically fixed on one side of the Y-axis pushing plate, a support rod is fixedly arranged between the L-shaped support members, the support rod is rotatably arranged inside the corresponding connecting sleeve, a linkage frame is fixedly arranged between the L-shaped support members, and one end of the linkage frame slides through the corresponding limiting part.

[0015] The present invention has the following beneficial effects: 1. The present invention uses the rotation of the casting conveyor belt to make the metal casting pass through the X-axis alignment port and enter the X-axis guide cavity. During this process, the position of the metal casting in the X-axis direction is corrected by the X-axis alignment port. The entire dressing mechanism is controlled by the steering screw to move from the first turning point to the second turning point. During this process, the metal casting between the two Y-axis push plates is pushed from the Y-axis alignment port to the Y-axis guide cavity. The position of the metal casting in the Y-axis direction is corrected again by the Y-axis alignment port. Thus, the position of the metal casting in the movement process is corrected by the combined action of the X-axis alignment port and the Y-axis alignment port. This ensures that the metal casting at the second turning point maintains a concentric position with the concentric dressing part, thereby achieving precise positioning of the metal casting and the concentric dressing part in the movement process.

[0016] 2. After the gate is removed, the present invention controls the rotation of the entire steering power mechanism to move the trimming mechanism above the casting conveyor belt. During this process, since the concentric trimming part is still fitted onto the metal casting, the metal casting after the gate is removed is pushed by the concentric trimming part to slide from the second steering point to the arc-shaped return seat, and then slides along the arc-shaped return seat onto the casting conveyor belt. As the casting conveyor belt continues to rotate, the metal casting that returns to the casting conveyor belt through the arc-shaped return seat continues to be conveyed to the rear end. In this way, the simultaneous conveying of unprocessed and processed metal castings can be completed through the same belt conveyor system, which greatly reduces the manufacturing cost of the casting trimming device.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] For a specific implementation example, please refer to Implementation Example 1. Figure 1-13 This invention relates to a finishing device for metal casting, comprising a casting conveying mechanism 1, which includes a casting conveyor belt 101 (it should be noted that the casting conveyor belt 101 is a major component of a common belt conveyor system in the prior art; other components of the belt conveyor system are not shown in the figure). A conveyor belt support platform 102 is provided on the inner side of the casting conveyor belt 101, which supports the inner top surface of the casting conveyor belt 101, thereby supporting the metal casting 4 conveyed on the casting conveyor belt 101. The contact surface between the conveyor belt support platform 102 and the casting conveyor belt 101 is designed to be smooth to reduce wear. An X-axis guide rail 103 and a Y-axis guide rail 104, which are interconnected, are mounted on the top of the conveyor belt support platform 102 (the X-axis and Y-axis directions are as follows...). Figure 2 As shown), an arc-shaped return seat 105 for docking with the casting conveyor belt 101 is connected to one side of the Y-axis guide rail 104. The metal casting 4 after the gate 9 is removed returns to the casting conveyor belt 101 along the arc-shaped return seat 105 under the action of external force, and the casting conveyor belt 101 continues to transport the metal casting 4.

[0035] A steering power mechanism 2 is rotatably mounted above the casting conveyor belt 101 (this steering power mechanism 2 is rotatably mounted on an external frame for support). A dressing mechanism 3 is slidably mounted at the bottom of the steering power mechanism 2. The steering power mechanism 2 includes a steering screw 201 threadedly connected to the dressing mechanism 3. The intersection of the X-axis guide rail 103 and the Y-axis guide rail 104 forms a first steering point, and the intersection of the Y-axis guide rail 104 and the arc-shaped return seat 105 forms a second steering point. The steering screw 201 is used to control the reciprocating motion of the dressing mechanism 3 between the first and second steering points. Initially, the dressing mechanism 3 is arranged along the Y-axis direction and is located at one of the steering points. The dressing mechanism 3 includes... The system includes two symmetrically arranged Y-axis push plates 801, with a concentric trimming component 504 between them. Initially, the horizontal distance between the two Y-axis push plates 801 is the same as the inner width of the X-axis guide rail 103, and the bottoms of both Y-axis push plates 801 are attached to the top of the X-axis guide rail 103. The casting conveyor belt 101 is used to transport the metal casting 4 to turning point one, and the Y-axis push plates 801 are used to transport the metal casting 4 to turning point two. The concentric trimming component 504 removes the circumferential gate 9 of the metal casting 4 through lifting and lowering motion. The steering power mechanism 2 rotates 90° to transport the trimmed metal casting 4 along the arc-shaped return seat 105 onto the casting conveyor belt 101.

[0036] In this embodiment of the invention, such as Figure 4 and Figure 5 As shown, the casting conveying mechanism 1 also includes a support frame 106 for mounting the conveyor belt support platform 102. A Y-axis support seat 107 is fixedly installed on the side of the conveyor belt support platform 102 near the Y-axis guide rail 104. A discharge motor 108 is installed on one side of the Y-axis support seat 107. The output end of the discharge motor 108 is connected to a discharge screw 109. The bottom of the X-axis guide rail 103 is attached to the top of the casting conveyor belt 101. The bottom of the Y-axis guide rail 104 is attached to the top of the Y-axis support seat 107. The bottom of the arc-shaped return seat 105 is attached to the top of the conveyor belt support platform 102.

[0037] Furthermore, the X-axis guide rail 103 is composed of an X-axis alignment port 110 and an X-axis guide channel 111, and the Y-axis guide rail 104 is composed of a Y-axis alignment port 112 and a Y-axis guide channel 113. The X-axis guide channel 111 and the Y-axis guide channel 113 are connected through the Y-axis alignment port 112. One end of the arc-shaped return seat 105 is attached to the casting conveyor belt 101, and the other end of the arc-shaped return seat 105 is connected to the Y-axis guide channel 113. The top of the Y-axis support seat 107 is fixed with a scraper 114 located at the end of the Y-axis guide rail 104. The scraper 114 is used to push the gate 9 that has been removed and fallen into the Y-axis guide channel 113 out of the Y-axis guide channel 113 for collection.

[0038] In this embodiment of the invention, such as Figure 1and Figure 6 As shown, an L-shaped support 115 is slidably disposed inside the Y-axis support 107. The top surface of the L-shaped support 115, the top surface of the casting conveyor belt 101, and the inner bottom surface of the arc-shaped return seat 105 are flush with each other. An internally threaded tube 116 is fixed on one side of the L-shaped support 115 and sleeved on the unloading screw 109. The internally threaded tube 116 is threadedly connected to the unloading screw 109. Initially, the front end of the L-shaped support 115 is close to the side of the casting conveyor belt 101 to ensure that the metal casting 4 in the X-axis guide cavity 111 can slide along the Y-axis guide rail 104 into the L-shaped support 115 and slide along the L-shaped support 115 to the turning point two.

[0039] In this embodiment of the invention, such as Figure 7 As shown, the steering power mechanism 2 also includes a rotary mounting bracket 202. A bearing plate 203 coaxial with the bottom of the rotary mounting bracket 202 is fixed. The rotary mounting bracket 202 is rotatably mounted on the external frame, thereby supporting the entire steering power mechanism 2. At the same time, a drive motor is mounted on the external frame. The output shaft of the drive motor is connected to a drive gear. An arc-shaped gear seat that meshes with the drive gear is fixedly mounted on the circumferential side of the bearing plate 203 (the above structure is a conventional setting in the prior art and is therefore not shown in the figure). A horizontal extension platform 204 is fixed on the circumferential side of the bearing plate 203. A radial channel 205 is provided between the horizontal extension platform 204 and the bearing plate 203. A guide shaft 206 is fixed on one side of the radial channel 205, and a steering screw 201 is rotatably mounted on the other side of the radial channel 205. A steering motor 207 mounted on the motor mount on the top of the bearing plate 203 is connected to the steering screw 201. The smooth movement of the entire trimming mechanism 3 on the bearing plate 203 is achieved through the cooperation of the guide shaft 206 and the steering screw 201.

[0040] Specific embodiment two, based on specific embodiment one, such as Figure 8 , Figure 10 and Figure 11As shown, the trimming mechanism 3 includes a trimming component 5; wherein, the trimming component 5 includes a movable carrier plate 501 that slides against the bottom of the carrier plate 203, a connecting seat 502 that slides with the radial channel 205 fixed on the top of the movable carrier plate 501, the connecting seat 502 being sleeved between the guide shaft 206 and the steering screw 201, and the steering screw 201 being threadedly connected to the connecting seat 502, and a trimming cylinder 503 located inside the radial channel 205 mounted on the top of the movable carrier plate 501, the output shaft of the trimming cylinder 503 being connected to a concentric trimming cylinder 503. The concentric trimming part 504 has the same inner diameter as the metal casting 4 to ensure that it can be fitted onto the metal casting 4 to remove the gate 9 when it moves downward. Two sets of mounting seats 505 are symmetrically fixed at the bottom of the moving carrier plate 501. Each set of mounting seats 505 has a vertical guide seat 506 fixed on one side. The vertical guide seat 506 has a limit part 6 slidably set inside. A lifting frame 507 is fixedly installed on the output shaft of the trimming cylinder 503. Vertical toothed plates 508 are fixed on opposite sides of the lifting frame 507.

[0041] In this embodiment of the invention, such as Figure 9 and Figure 12 As shown, the trimming mechanism 3 also includes a transmission assembly 7; wherein, the transmission assembly 7 includes a rotating cylinder 701 disposed below the movable carrier plate 501, and a support shaft 702 coaxial with it is provided on the inner side of the rotating cylinder 701. Each set of mounting seats 505 is rotatably connected to the corresponding support shaft 702. The rotating cylinder 701 and the support shaft 702 are connected by a fixing member 703 (that is, the support shaft 702 drives the rotating cylinder 701 to rotate synchronously through the fixing member 703). A transmission gear 704 that meshes with the vertical toothed plate 508 is fixedly installed at the end of the support shaft 702, and a connecting sleeve 705 is fixedly installed on the inner wall of the rotating cylinder 701.

[0042] In this embodiment of the invention, such as Figure 9 and Figure 13 As shown, the trimming mechanism 3 also includes a pushing component 8; wherein, the pushing component 8 includes a Y-axis pushing plate 801, two L-shaped support members 802 are symmetrically fixed on one side of the Y-axis pushing plate 801, and a support rod 803 is fixedly arranged between the L-shaped support members 802. The support rod 803 is rotatably arranged inside the corresponding connecting sleeve 705, so that the pushing component 8 can be driven to move up and down through the circumferential movement of the connecting sleeve 705. During the up and down movement, the pushing component 8 moves horizontally simultaneously. A linkage frame 804 is fixedly arranged between the L-shaped support members 802. One end of the linkage frame 804 slides through the corresponding limiting part 6. Through the cooperation between the linkage frame 804 and the limiting part 6, it is ensured that the pushing component 8 will not tilt during the movement (that is, the pushing component 8 always remains horizontal).

[0043] like Figure 3 As shown in (A1), the trimming mechanism 3 is at turning point one at this time, as... Figure 3 As shown in (A2), the dressing mechanism 3 is at turning point two. The rotation of the casting conveyor belt 101 causes the metal casting 4 to pass through the X-axis alignment port 110 and enter the X-axis guide cavity 111. During this process, the X-axis alignment port 110 corrects the position of the metal casting 4 in the X-axis direction. When the metal casting 4 on the front side is transported to turning point one, the casting conveyor belt 101 stops running. At this time, the metal casting 4 on the front side is between the two Y-axis push plates 801. Then, the steering motor 207 is started to drive the steering screw 201 to rotate. The steering screw 201 controls the entire dressing mechanism 3 from turning point one. The metal casting 4 moves from the Y-axis alignment port 112 to the Y-axis guide cavity 113 via the two Y-axis push plates 801 during the movement to the second turning point. The position of the metal casting 4 in the Y-axis direction is corrected again by the Y-axis alignment port 112. Thus, the position of the metal casting 4 during the movement is corrected by the combined action of the X-axis alignment port 110 and the Y-axis alignment port 112. This ensures that the metal casting 4 at the second turning point maintains a concentric position with the concentric trimmer 504, thereby achieving precise positioning of the metal casting 4 and the concentric trimmer 504 during the movement.

[0044] Next, the dressing cylinder 503 is activated to control the concentric dressing component 504 to move downwards. The synchronously moving lifting frame 507 drives the vertical toothed plate 508 downwards and rotates the transmission gear 704. The support shaft 702, rotating synchronously with the transmission gear 704, drives the rotating cylinder 701 to rotate synchronously. Under the cooperation of the connecting sleeve 705 and the support rod 803, the pushing assembly 8 is driven upwards and horizontally away from the concentric dressing component 504. The downward-moving concentric dressing component 504 is fitted onto the metal casting 4, cutting off its gate 9. The cut-off gate 9 falls into the L-shaped support seat 115 within the Y-axis guide cavity 113. After the gate 9 is removed, the entire steering power mechanism 2 is rotated 90° to... The dressing mechanism 3 moves above the casting conveyor belt 101. During this process, since the concentric dressing component 504 is still fitted onto the metal casting 4, the concentric dressing component 504 pushes the metal casting 4, after the gate 9 has been removed, to slide from the turning point two into the arc-shaped return seat 105, and then slides along the arc-shaped return seat 105 onto the casting conveyor belt 101. Subsequently, the dressing cylinder 503 controls the concentric dressing component 504 to move upward a certain distance, causing the concentric dressing component 504 to detach from the casting 4. The upward-moving vertical toothed plate 508 drives the transmission gear 704 to rotate in the opposite direction, driving the pushing component 8 to move downward while moving horizontally towards the concentric dressing component 504. Then, by controlling the entire steering power mechanism 2 to rotate in the opposite direction by 90°, the reset is completed (i.e., returning to the starting point). Figure 1At the indicated position), the concentric dressing component 504 continues to move upwards under the control of the dressing cylinder 503 until the reset is completed. The pushing components 8 on both sides move closer to each other again until the reset is completed. Then, the entire dressing mechanism 3 is controlled to move from the second turning point to the first turning point (i.e., the dressing mechanism 3 returns to the initial position) by the reverse rotation of the steering screw 201. Then, the unloading motor 108 is started to drive the unloading screw 109 to rotate. Under the threaded engagement of the unloading screw 109 and the internal threaded tube 116, the L-shaped support 115 is driven to move a distance away from the casting conveyor belt 101. The scraper plate 114 removes the lower part of the casting. The gate 9 that falls into the Y-axis guide cavity 113 is pushed out of the Y-axis guide cavity 113 and collected (collected by a collection box located below the scraper plate 114). After the L-shaped support seat 115 is moved in the reverse direction to complete the reset, the gate 9 on the periphery of the metal casting 4 can be removed one after another according to the same control method. The metal casting 4 returns to the casting conveyor belt 101 through the arc-shaped return seat 105 and continues to be transported to the rear end. In this way, the unprocessed metal casting 4 and the processed metal casting 4 can be transported at the same time through the same belt transmission system, which greatly reduces the manufacturing cost of the casting finishing device.
