Description

Technical Field

[0001] The present invention belongs to the technical field of cutting devices, and particularly relates to a cutting device for stainless steel castings. Background Art

[0002] Stainless steel castings refer to components or workpieces manufactured by casting processes using stainless steel materials. Stainless steel is an alloy containing at least 10.5% chromium, with excellent corrosion resistance, high-temperature resistance, and good mechanical properties. Due to these characteristics, stainless steel castings are widely used in many industries, such as chemical, food processing, aviation, machinery, marine, and other fields. After stainless steel castings are formed by casting, it is necessary to cut the redundant sprue parts to ensure the aesthetics of their appearance and overall performance. The cutting of stainless steel castings requires the selection of appropriate cutting techniques and tools to ensure smooth, precise cutting without damaging the castings.

[0003] Common cutting methods for stainless steel castings include laser cutting, water jet cutting, plasma cutting, circular saw cutting, and mechanical grinding, etc. For some thicker castings, plasma cutting is generally used. The gas is heated to a high temperature by an electric arc to make it a plasma, and then the material is cut. There are various types of plasma cutting equipment on the market currently, but the structural designs of most current plasma cutting equipment are too simple. During actual use of the equipment, it is necessary for workers to clamp and fix the stainless steel casting to be cut on the chuck of the equipment, and then drive the casting to rotate synchronously through the rotation of the chuck. At this time, the plasma cutting assembly set at a fixed position can perform rotary cutting on the sprue part of the casting. This cutting method is not only time-consuming and laborious, with low efficiency, but also unable to ensure high processing accuracy. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a cutting device for stainless steel castings.

[0005] The technical solution adopted to solve the above technical problem is: A cutting device for stainless steel castings, including a support mechanism. The support mechanism includes a support frame. A casting conveying mechanism is arranged on the periphery of the support frame. An adjustable conveying structure is installed inside the support frame for the directional conveyance of castings and can be retracted during the cutting process;

[0006] Two groups of casting clamping mechanisms are symmetrically installed on the inner side of the support frame for stably clamping the castings during the cutting process. A cutting adjustment mechanism is slidably installed on the top of the support frame, and a plasma cutting assembly for cutting the castings is fixedly installed on the cutting adjustment mechanism;

[0007] It further includes a casting tray for precisely placing and positioning castings. One side at the rear end of the support frame is fixedly connected with a guiding frame for positioning and righting the casting tray before it enters the adjustable conveying structure.

[0008] One side of the inner wall of the support frame is equipped with a photoelectric induction switch that matches the casting tray.

[0009] Furthermore, a contraction groove is formed on one side of the support frame, a discharge chute is also formed at the bottom of the support frame, a rotating bracket is provided on one side of the inner wall of the support frame, and installation grooves are formed in the middle of both sides of the support frame.

[0010] Through the above technical solution, the discharge chute is designed with an inclined structure, and the outlet of the discharge chute faces the outside of the support frame. Therefore, when the adjustable conveying structure is in a contracted state, the casting tray dropped from the adjustable conveying structure and the sprue waste generated after cutting can both naturally fall onto the discharge chute and be discharged outward along its inclined surface.

[0011] Furthermore, the casting conveying mechanism includes a loading and unloading conveyor frame, a feeding conveyor frame, and a discharging conveyor frame. The loading and unloading conveyor frame, the feeding conveyor frame, and the discharging conveyor frame are in a C-shaped semi-surrounding support frame and are closely connected to the front and rear ends of the adjustable conveying structure.

[0012] Through the above technical solution, the casting conveying mechanism is mainly used for the automatic conveying of stainless steel castings. During actual processing, the casting tray for placing stainless steel castings can be horizontally placed on the loading and unloading conveyor frame, and then the stainless steel casting to be cut is placed on the casting tray. At this time, the loading and unloading conveyor frame will drive the casting tray for conveying and naturally transition to the feeding conveyor frame. Then, through the continuous conveying of the feeding conveyor frame, the casting tray will enter the adjustable conveying structure. When the metal casting is cut, the metal casting will fall on the adjustable conveying structure and then enter the discharging conveyor frame under the conveying of the adjustable conveying structure, and finally be conveyed to the loading position of the loading and unloading conveyor frame. Through the mutual cooperation of the casting conveying mechanism and the adjustable conveying structure, a set of circular conveying structure can be formed, and loading and unloading are at the same position. Workers only need to complete the operations of placing and taking castings, making the entire processing process very convenient and fast. At the same time, a large amount of manpower and material resources are saved, and the processing time is saved.

[0013] Furthermore, the adjustable conveying structure includes a directional conveyor frame rotatably connected to the rotating bracket. The center of the bottom of the directional conveyor frame is fixedly connected with a first rotating support. A second rotating support is provided at the bottom of the contraction groove. An adjusting hydraulic cylinder is rotatably connected between the first rotating support and the second rotating support.

[0014] Through the above technical solution, when the stainless steel casting is conveyed to the designated position on the directional conveyor rack, the clamping mechanisms on both sides will firmly clamp the stainless steel casting. At this time, the piston rod of the adjusting hydraulic cylinder will start to contract, and at this time, the directional conveyor rack will rotate on the rotating bracket, so that the directional conveyor rack can be in an inward-tilting storage state with an angle greater than the vertical angle, while the stainless steel casting is in a suspended processing state. During the cutting process, the metal waste chip jet generated by cutting will neither contact the directional conveyor rack nor accumulate on the directional conveyor rack, thus playing a better protective role for the directional conveyor rack and ensuring its conveying accuracy during continuous operation; after the cutting process is completed, the adjusting hydraulic cylinder will drive the directional conveyor rack to reset and be in a horizontal state. When the clamping mechanisms on both sides unlock the clamping and fixing of the stainless steel casting, the cut stainless steel casting will naturally fall onto the directional conveyor rack and then enter above the discharge conveyor rack under the conveyance of the directional conveyor rack.

[0015] Further, the casting clamping mechanism includes a clamping hydraulic cylinder installed in the installation groove. The output end of the clamping hydraulic cylinder is fixedly connected with a main clamping plate. The middle of the end of the main clamping plate away from the clamping hydraulic cylinder is fixedly connected with an inner fixing plate. A plurality of fixing rods are slidably installed on the periphery of the main clamping plate. One end of each of the plurality of fixing rods is fixedly connected with a limit fixing block, and the other end of each of the plurality of fixing rods is fixedly connected with a clamping end fixing block. A clamping spring is sleeved on the outer wall of each of the plurality of fixing rods. Rubber anti-slip pads are fixedly connected to the outer sides of the plurality of clamping end fixing blocks and the outer side of the inner fixing plate.

[0016] Through the above technical solution, when the casting tray loaded with the stainless steel casting moves to the designated position, the clamping hydraulic cylinders on both sides will work simultaneously. The piston rods of the clamping hydraulic cylinders will extend inward simultaneously, and then drive the two main clamping plates to quickly approach the stainless steel casting. During the continuous contact and extrusion process, multiple groups of fixing rods and clamping end fixing blocks will slide on the main clamping plate and squeeze the corresponding clamping springs. Under the elastic reaction force of the clamping springs, the plurality of clamping end fixing blocks on both sides will firmly clamp the stainless steel casting, and at the same time, the corresponding inner fixing plates will also be closely attached to the middle parts on both sides of the stainless steel casting. When the directional conveyor rack is in the storage state, the stainless steel casting is in a suspended clamping state at this time, so as to ensure that no damage will be caused to other equipment structures during the subsequent cutting process. Further, rubber anti-slip pads are provided on the outer sides of the clamping end fixing blocks and the outer side of the inner fixing plate, which can play an anti-slip role during the clamping process, thus ensuring the stability of the clamping.

[0017] Further, a plurality of round holes for the fixing rods to penetrate are formed on the periphery of the main clamping plate, and the clamping spring is located on the side close to the clamping end fixing block.

[0018] Furthermore, the cutting adjustment mechanism includes two fixed slide rails fixed to the top of the support frame. The outer sides of the two fixed slide rails are both slidably connected with limit sliders. The centers of the tops of the two limit sliders are fixedly connected with lifting guide rods. The tops of the two lifting guide rods are fixedly connected with a support plate. A lifting cylinder is installed at the center of the top of the support plate. The outer walls of the two lifting guide rods are slidably connected with a lifting bracket. The center of the bottom of the lifting bracket is rotatably connected with a ball screw. A ball nut seat is installed on the ball screw. The bottom of the ball nut seat is fixedly connected with a mounting frame. A servo motor for driving the ball screw to rotate is also installed on the lifting bracket.

[0019] Through the above technical solution, the cutting adjustment mechanism is mainly used to adjust the position of the plasma cutting assembly in the X-axis, Y-axis and Z-axis directions to meet different cutting requirements. During the actual working process, the position in the Y-axis direction can be adjusted by the limit slider sliding on the fixed slide rail. When continuously processing stainless steel castings of the same specification, the position adjustment in the Y-axis direction can be fixed and no longer adjusted after being fixed; the lifting cylinder can drive the plasma cutting assembly to adjust in the Z-axis direction. During actual work, the lifting cylinder can drive the lifting bracket to lift through the telescopic movement of the piston rod to achieve height adjustment; furthermore, the servo motor can drive the plasma cutting assembly to adjust in the X-axis direction. During the cutting process, since the excess water ports on the stainless steel casting need to be cut off, the output shaft of the servo motor is required to drive the ball screw to rotate at a constant speed, and then the ball nut seat and the plasma cutting assembly can be driven to move smoothly horizontally, thus completing the cutting operation of the water ports.

[0020] Furthermore, the plasma cutting assembly is fixed to the bottom of the mounting frame.

[0021] Through the above technical solution, when the plasma cutting assembly is working, the high-voltage current it releases forms a plasma arc when passing through the gas. The gas will be heated to a sufficient temperature by the arc, causing the molecules, atoms and even electrons in the gas to ionize, forming a plasma. The arc is concentrated in the cutting area. The metal is heated to the melting point by the ejected high-temperature plasma stream, the metal is melted and blown away. Under the horizontal driving and adjusting action of the cutting adjustment mechanism, a clean cutting seam can be formed at the water port position of the stainless steel casting, thus completing the automatic cutting operation.

[0022] Furthermore, the casting tray includes a tray body, and metal positioning patches are installed at the front and rear ends on both sides of the tray body.

[0023] Through the above technical solution, the tray body is mainly used to place stainless steel castings. Under the transmission of the casting transmission mechanism and through the guiding and straightening effects of the guiding frame, the tray body will move smoothly and accurately onto the directional transmission frame and be transmitted along a fixed route. Metal positioning patches are installed at the front and rear ends on both sides of the tray body. When the photoelectric induction switch installed on one side of the inner wall of the support frame accurately detects the corresponding metal positioning patch, the photoelectric induction switch will convert the detection signal into an electrical signal and transmit the control command to the drive unit of the directional transmission frame to control it to stop working, so that the tray body and the stainless steel casting can stay at the designated position for subsequent precise clamping.

[0024] Further, a protective curtain is fixedly installed at the top of the front opening of the support frame to block the metal jet generated during the cutting process.

[0025] The beneficial effects of the present invention are as follows: (1) By designing a casting transmission mechanism in a C-shaped semi-surrounding structure and cooperating with an adjustable transmission structure, the present invention can realize the automatic feeding and transmission of stainless steel castings. Workers only need to complete the loading and unloading operations, which not only saves time and effort but also has lower technical requirements for operators; (2) By designing an adjustable transmission structure, a casting clamping mechanism, and a cutting adjustment mechanism, the present invention can automatically complete precise transmission, clamping, and cutting operations of stainless steel castings without manual intervention throughout the process, which not only ensures the processing efficiency and accuracy but also can be flexibly adjusted according to the sprue position of the casting to adapt to the cutting processing of different castings; (3) By designing a split-type transmission structure and designing the adjustable transmission structure into a retractable structure, the metal waste jet generated by cutting will neither contact the directional transmission frame nor accumulate on the directional transmission frame, which can better protect the directional transmission frame and at the same time ensure its transmission accuracy during continuous operation.

Detailed implementation manners

[0042] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] As Figures 1 - 15 shown, a cutting device for stainless steel castings in this embodiment includes a support mechanism 1. The support mechanism 1 includes a support frame 101. A shrinkage groove 102 is formed on one side of the support frame 101, and a discharge groove 103 is further formed at the bottom of the support frame 101. A rotating bracket 104 is provided on one side of the inner wall of the support frame 101. Installation grooves 105 are formed in the middle of both sides of the support frame 101. The discharge groove 103 is designed with an inclined structure, and the outlet of the discharge groove 103 faces the outside of the support frame 101. Therefore, when the adjustable conveying structure 3 is in a contracted state, the casting tray 7 dropped from the adjustable conveying structure 3 and the sprue waste generated after cutting can both naturally fall onto the discharge groove 103 and be discharged outward along its inclined surface.

[0044] Regarding the casting conveying mechanism 2, refer to Figures 1 - 7 , a casting conveying mechanism 2 is arranged on the periphery of the support frame 101. The casting conveying mechanism 2 includes a loading and unloading conveying frame 201, a feeding conveying frame 202 and a discharging conveying frame 203. The loading and unloading conveying frame 201, the feeding conveying frame 202 and the discharging conveying frame 203 are in a C-shaped semi-surrounding support frame 101 and are closely connected to the front and rear ends of the adjustable conveying structure 3. The casting conveying mechanism 2 is mainly used for the automatic conveying of stainless steel castings. During actual processing, the casting tray 7 for placing stainless steel castings can be horizontally placed on the loading and unloading conveying frame 201, and then the stainless steel casting to be cut is placed on the casting tray 7. At this time, the loading and unloading conveying frame 201 will drive the casting tray 7 for conveying and naturally transition to the feeding conveying frame 202. Then, through the continuous conveying of the feeding conveying frame 202, the casting tray 7 will enter the adjustable conveying structure 3. When the metal casting is cut, the metal casting will fall on the adjustable conveying structure 3 and then enter the discharging conveying frame 203 under the conveying of the adjustable conveying structure 3, and finally be conveyed to the loading position of the loading and unloading conveying frame 201. Through the mutual cooperation of the casting conveying mechanism 2 and the adjustable conveying structure 3, a set of circular conveying structures can be formed, and the loading and unloading are at the same position. Workers only need to complete the operations of placing and taking the castings, with low technical requirements, making the entire processing process very convenient and fast, while saving a large amount of manpower and material resources and saving processing time.

[0045] Regarding the adjustable conveying structure 3, refer to Figures 8 - 10, an adjustable conveying structure 3 is installed inside the support frame 101 for the directional conveyance of castings and can be retracted during the cutting process; the adjustable conveying structure 3 includes a directional conveying frame 301 rotatably connected to the rotating bracket 104, a first rotating support 302 is fixedly connected to the center of the bottom of the directional conveying frame 301, a second rotating support 304 is provided at the bottom of the contraction groove 102, and an adjusting hydraulic cylinder 303 is rotatably connected between the first rotating support 302 and the second rotating support 304. After the stainless steel casting is conveyed to the designated position on the directional conveying frame 301, the clamping mechanisms 4 on both sides will tightly clamp the stainless steel casting. At this time, the piston rod of the adjusting hydraulic cylinder 303 will start to contract, and at this time, the directional conveying frame 301 will rotate on the rotating bracket 104, so that the directional conveying frame 301 can be in an inwardly inclined retracted state with an angle greater than the vertical angle, while the stainless steel casting is in a suspended machining state. During the cutting process, the metal waste chip jet generated by cutting will neither contact the directional conveying frame 301 nor accumulate on the directional conveying frame 301, which can better protect the directional conveying frame 301 and also ensure its conveying accuracy during continuous operation; after the cutting process is completed, the adjusting hydraulic cylinder 303 will drive the directional conveying frame 301 to reset and be in a horizontal state. After the clamping mechanisms 4 on both sides unlock the clamping and fixing of the stainless steel casting, the cut stainless steel casting will naturally fall onto the directional conveying frame 301 and then enter above the discharge conveying frame 203 under the conveyance of the directional conveying frame 301.

[0046] Regarding the casting clamping mechanism 4, refer to Figures 11 - 12, on the inner side of the support frame 101, two sets of casting clamping mechanisms 4 are symmetrically installed for stably clamping the casting during the cutting process. The casting clamping mechanism 4 includes a clamping hydraulic cylinder 401 installed in the installation groove 105. The output end of the clamping hydraulic cylinder 401 is fixedly connected with a main clamping plate 402. In the middle of the end of the main clamping plate 402 far away from the clamping hydraulic cylinder 401, an inner fixing plate 403 is fixedly connected. A plurality of fixing rods 404 are slidably installed on the periphery of the main clamping plate 402. One end of each of the plurality of fixing rods 404 is fixedly connected with a limit fixing block 405, and the other end of each of the plurality of fixing rods 404 is fixedly connected with a clamping end fixing block 406. A clamping spring 407 is sleeved on the outer wall of each of the plurality of fixing rods 404. Rubber anti-slip pads 408 are fixedly connected to the outer sides of the plurality of clamping end fixing blocks 406 and the outer side of the inner fixing plate 403. When the casting tray 7 loaded with stainless steel castings moves to the designated position, the clamping hydraulic cylinders 401 on both sides will work simultaneously, and the piston rods of the clamping hydraulic cylinders 401 will extend inward simultaneously, thereby driving the two main clamping plates 402 to quickly approach the stainless steel casting. During the continuous contact and extrusion process, the multiple groups of fixing rods 404 and the clamping end fixing blocks 406 will slide on the main clamping plate 402 and squeeze the corresponding clamping springs 407. Under the elastic reaction force of the clamping springs 407, the plurality of clamping end fixing blocks 406 on both sides will tightly clamp the stainless steel casting, and at the same time, the corresponding inner fixing plate 403 will also be closely attached to the middle parts on both sides of the stainless steel casting. When the directional transfer frame 301 is in the storage state, at this time, the stainless steel casting is in a suspended clamping state, so as to ensure that no damage will be caused to other equipment structures during the subsequent cutting process. Further, rubber anti-slip pads 408 are provided on the outer sides of the clamping end fixing blocks 406 and the outer side of the inner fixing plate 403, which can play an anti-slip role during the clamping process, thereby ensuring the stability of the clamping.

[0047] In this embodiment, further, a plurality of round holes for the fixing rods 404 to penetrate are formed on the periphery of the main clamping plate 402, and the clamping spring 407 is located on the side close to the clamping end fixing block 406.

[0048] Regarding the cutting adjustment mechanism 5, refer to Figures 13 - 14, a cutting adjustment mechanism 5 is slidably installed on the top of the support frame 101, and a plasma cutting assembly 6 for casting cutting is fixedly installed on the cutting adjustment mechanism 5; the cutting adjustment mechanism 5 includes two fixed slide rails 510 fixed to the top of the support frame 101, and limiting sliders 501 are slidably connected to the outer sides of the two fixed slide rails 510. The centers of the tops of the two limiting sliders 501 are fixedly connected with lifting guide rods 502, the tops of the two lifting guide rods 502 are fixedly connected with a support plate 503, a lifting cylinder 504 is installed at the center of the top of the support plate 503, a lifting bracket 505 is slidably connected to the outer walls of the two lifting guide rods 502, a ball screw 506 is rotatably connected to the center of the bottom of the lifting bracket 505, a ball nut seat 507 is installed on the ball screw 506, the bottom of the ball nut seat 507 is fixedly connected with a mounting frame 508, and a servo motor 509 for driving the ball screw 506 to rotate is also installed on the lifting bracket 505. The cutting adjustment mechanism 5 is mainly used to adjust the position of the plasma cutting assembly 6 in the X-axis, Y-axis and Z-axis directions to meet different cutting requirements. In the actual working process, the position in the Y-axis direction can be adjusted by sliding the limiting slider 501 on the fixed slide rail 510. When continuously processing stainless steel castings of the same specification, the position adjustment in the Y-axis direction can be fixed and no longer adjusted; the lifting cylinder 504 can drive the plasma cutting assembly 6 to adjust in the Z-axis direction. During actual work, the lifting cylinder 504 can drive the lifting bracket 505 to lift through the telescopic movement of the piston rod to achieve height adjustment; further, the servo motor 509 can drive the plasma cutting assembly 6 to adjust in the X-axis direction. During the cutting process, since the excess water inlet on the stainless steel casting needs to be cut off, the output shaft of the servo motor 509 needs to drive the ball screw 506 to rotate at a constant speed, and then the ball nut seat 507 and the plasma cutting assembly 6 can be driven to move smoothly horizontally, thereby completing the cutting operation of the water inlet.

[0049] The plasma cutting assembly 6 is fixed to the bottom of the mounting frame 508. When the plasma cutting assembly 6 is working, the high-voltage current it releases forms a plasma arc when passing through a gas (usually air, nitrogen or oxygen). The gas will be heated by the arc to a sufficient temperature, causing the molecules, atoms and even electrons in the gas to be ionized to form a plasma. The arc is concentrated in the cutting area, and the metal is heated to the melting point by the sprayed high-temperature plasma stream, melting the metal and blowing it away. Under the horizontal drive and adjustment of the cutting adjustment mechanism 5, a clean cutting seam can be formed at the water inlet position of the stainless steel casting, thus completing the automated cutting operation.

[0050] The device further includes a casting tray 7 for accurately placing and positioning castings. One side at the rear end of the support frame 101 is fixedly connected with a guiding frame 8 for positioning and righting the casting tray 7 before it enters the adjustable conveying structure 3. On one side of the inner wall of the support frame 101, a photoelectric induction switch 9 matching the casting tray 7 is installed. The casting tray 7 includes a tray body 701, and metal positioning patches 702 are installed at the front and rear ends on both sides of the tray body 701. The tray body 701 is mainly used for placing stainless steel castings. Under the conveyance of the casting conveying mechanism 2 and through the guiding and righting effects of the guiding frame 8, the tray body 701 will move smoothly and accurately onto the directional conveying frame 301 and be conveyed along a fixed route. Metal positioning patches 702 are installed at the front and rear ends on both sides of the tray body 701. When the photoelectric induction switch 9 installed on one side of the inner wall of the support frame 101 accurately detects the corresponding metal positioning patch 702, the photoelectric induction switch 9 will convert the detection signal into an electrical signal and transmit a control command to the driving unit of the directional conveying frame 301 to control it to stop working, so that the tray body 701 and the stainless steel casting can stay at the designated position for subsequent precise clamping.

[0051] At the top of the front-end opening of the support frame 101, a protective curtain 10 is fixedly installed to block the metal jets generated during the cutting process to prevent the splashing metal jets from spreading to the outside.

[0052] The working principle of this embodiment is as follows. During processing, the casting tray 7 for placing stainless steel castings can be horizontally placed on the loading and unloading conveying frame 201, and then the stainless steel casting to be cut is placed on the casting tray 7. At this time, the loading and unloading conveying frame 201 will drive the casting tray 7 for conveyance and naturally transition to the feeding conveying frame 202. Then, through the continuous conveyance of the feeding conveying frame 202, the casting tray 7 will enter the adjustable conveying structure 3.

[0053] When the casting tray 7 loaded with stainless steel castings moves to the designated position, the clamping hydraulic cylinders 401 on both sides will work simultaneously, so that the stainless steel casting can be tightly clamped by multiple clamping end blocks 406. At this time, the piston rod of the adjusting hydraulic cylinder 303 will start to contract, and at this time, the directional conveying frame 301 will rotate on the rotating bracket 104, so that the directional conveying frame 301 can be in an inward-tilting storage state at an angle greater than the vertical angle, and at this time, the stainless steel casting is in a suspended clamping state.

[0054] At this time, the cutting adjustment mechanism 5 will drive the plasma cutting assembly 6 to move and adjust in the X-axis and Y-axis directions. Under the driving and adjusting action of the cutting adjustment mechanism 5, a clean cutting seam can be formed at the nozzle position of the stainless steel casting, thus completing the automated cutting operation.

[0055] After cutting is completed, the adjusting hydraulic cylinder 303 drives the directional conveyor frame 301 to reset and be in a horizontal state. When the clamping mechanisms 4 on both sides unlock the clamping and fixing of the stainless steel casting, the cut stainless steel casting will naturally fall onto the directional conveyor frame 301, and then, under the conveyance of the directional conveyor frame 301, it will be transferred above the discharge conveyor frame 203 and finally conveyed to the loading position of the loading and unloading conveyor frame 201. At this time, the operator only needs to remove it.

[0056] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
