[0033] In order to make the purpose, technical scheme and advantages of the present application more clear, the utility model will be described in further detail below with reference to the drawings.
[0034] It should be noted that the terms "first", "second" and the like (if any) in the specification of the present application are used to distinguish similar objects, and do not necessarily have to describe a particular order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are only examples of the utility model consistent with some aspects of the present application.
[0035] The subframe is an important part of the automobile, as the skeleton and connecting component of the front and rear axle of the automobile, through supporting and connecting the axle and the suspension system to the main frame, ensuring the stability and driving performance of the vehicle. With the rapid development of new energy automobile industry, lightweight has become the key to improve the energy efficiency and endurance of the vehicle, therefore, light materials such as aluminum alloy and advanced casting process such as sand core shell extraction casting technology are widely used in the manufacturing of subframe.
[0036] Sand core shell-extraction casting process forms the complete shape of the subframe by injecting liquid aluminum alloy into a pre-designed shell-extraction mold and shaking the internal sand core to remove the broken sand after cooling and solidification. The sand core shell-extraction casting process not only reduces the number of components of the subframe, eliminates the welding and assembly process, but also significantly reduces the weight of the subframe, thereby improving the overall performance of the vehicle.
[0037] However, the casting quality of the subframe depends on the design of the pouring system, especially the reasonable configuration of the riser, the blind riser, the sprue and the runner. The pouring system not only ensures that the liquid aluminum alloy can smoothly and orderly fill the mold cavity, but also maintains good flow state, pressure transmission and heat balance to avoid casting defects. The sprue, as the entrance of the liquid aluminum alloy into the mold, is usually equipped with a filter screen to filter out inclusions in the liquid aluminum alloy to ensure the quality of the casting. It can be seen Figure 1 The structure of a subframe sprue, riser and runner is shown. It includes a subframe body 1, a sprue 2, a runner 3, a riser 4 and a blind riser 5. Figure 1 The subframe shown adopts a sand core shell-extraction casting process. In the production of the subframe body 1, at least four sprues 2, multiple risers 4 and multiple runners 3 are connected between the subframe body 1 and the sprues 2 and the risers 4.
[0038] After the subframe is cast, the sprues 2, the risers 4 and the runners 3 located at the edge of the side wall of the casting need to be removed. Due to the complex structure and large size of the subframe product, the removal work needs to be performed using a special subframe sprue- riser-runner removal equipment. The blind riser 5 is not within the sawing range of the subframe sprue-riser-runner removal equipment and is removed by cutting in a later machining machine. After the sprues 2, the risers 4 and the runners 3 are removed, the remaining subframe body 1 can be seen Figure 2 A structure diagram of a subframe product is shown.
[0039] Exemplarily, the subframe sprue-riser-runner removal equipment cuts by using a high-speed rotating annular belt-shaped saw blade. However, the saw blade is easily damaged by the impact of the cut-off sprues 2, risers 4 and runners 3 when it is rotating at high speed, which increases the failure rate and maintenance cost of the equipment.
[0040] The utility model provides a kind of subframe sprue-riser-runner removal equipment anti-smashing device, reduce the possibility that belt-shaped saw blade of subframe sprue-riser-runner removal equipment is smashed. See Figures 3-7 , Figure 3 The structure diagram of a kind of subframe sprue-riser-runner removal equipment and anti-smashing device provided by the utility model, Figure 4 The shaft side schematic view of a kind of subframe sprue-riser-runner removal equipment and anti-smashing device provided by the utility model, Figure 5The utility model provides a kind of subframe pouring gate removal equipment anti-smashing device's structure schematic view, Figure 6 The utility model provides another kind of subframe pouring gate removal equipment and the structure schematic view of anti-smashing device, Figure 7 Another kind of subframe pouring gate removal equipment and the shaft side schematic view of anti-smashing device are provided for the utility model.The subframe pouring gate removal equipment anti-smashing device is applied to subframe pouring gate removal equipment.
[0041] Among them, subframe pouring gate removal equipment includes: installation foot 101, lower frame body 102, support column 103, upper frame body 104, power motor 105, upper belt wheel 106, lower belt wheel 107, belt saw blade 108, aluminum chip discharge port 109.Installation foot 101 and lower frame body 102 are integrated structure.There are multiple installation foot 101 in the bottom of lower frame body 102, and reinforcing rib plate is also designed on both sides of each installation foot 101, to strengthen the multidirectional lateral force of lower frame body 102, meet the safety and reliability of subframe pouring gate removal equipment load work.Multiple chemical anchor bolts are used to pass through installation foot 101, to fix installation foot 101 and lower frame body 102 on ground.
[0042] Lower frame body 102 is fixed by high-strength bolt connection installation support column 103, and support column 103 is fixed by high-strength bolt connection installation upper frame body 104, to form subframe pouring gate removal equipment main structure.Drive motor 105 is installed on the motor base inside lower frame body 102, and motor pulley is installed on the shaft end of drive motor 105, and motor pulley is connected with the shaft end of drive motor 105 by interference fit and through key.In the inside of lower frame body 102, lower bearing support is installed, and shaft shoulder is designed on the shaft of lower belt wheel 107, and lower belt wheel 107 shaft shoulder is connected with lower bearing support bearing inner hole by interference fit and through key lower belt wheel 107 shaft end pulley.Motor pulley and lower belt wheel 107 shaft end pulley are connected by multiple triangular belts, to realize the conversion of rotating speed and torque.Motor pulley and lower belt wheel 107 shaft end pulley are installed with motor belt cover outside.
[0043] The lower belt wheel 107 is formed with spokes and rims in a symmetrical hollow manner, which is beneficial to reducing the self weight and increasing the dynamic balance of the lower belt wheel 107. An aluminum chip discharge port 109 is mounted on the side of the lower frame body 102. An upper bearing support is mounted in the inside of the upper frame body 104, and a shaft shoulder is designed on the shaft of the upper belt wheel 106, and the shaft shoulder of the upper belt wheel 106 is in interference fit with the bearing inner hole of the upper bearing support. The upper belt wheel 106 is also formed with spokes and rims in a symmetrical hollow manner, which is beneficial to reducing the self weight and increasing the dynamic balance of the upper belt wheel 106. The belt saw blade 108 is directly sleeved on the rims of the upper belt wheel 106 and the lower belt wheel 107, and the direction of the saw blade is ensured to be downward. During the working process of the sub-frame sprue runner removal equipment, the aluminum chips cut by the belt saw blade 108 are discharged through the aluminum chip discharge port 109.
[0044] The anti-throwing device of the sub-frame sprue runner removal equipment comprises a sprue anti-throwing structure and a runner anti-throwing structure; in the case that the sub-frame sprue runner removal equipment is used to remove the sprue of the sub-frame, the sprue anti-throwing structure is connected to the sub-frame sprue runner removal equipment, and the sprue anti-throwing structure is used to separate the removed sprue and the sub-frame sprue runner removal equipment; in the case that the sub-frame sprue runner removal equipment is used to remove the runner of the sub-frame, the runner anti-throwing structure is connected to the sub-frame sprue runner removal equipment, and the runner anti-throwing structure is used to separate the removed runner and the sub-frame sprue runner removal equipment.
[0045] In order to be suitable for different use scenarios, i.e. the case that the sub-frame sprue runner removal equipment is used to remove the sprue (i.e. the sprue and the runner) of the sub-frame and the case that the sub-frame sprue runner removal equipment is used to remove the runner of the sub-frame, the utility model provides two different structural designs, which comprise a sprue anti-throwing structure and a runner anti-throwing structure.
[0046] The sprue anti-throwing structure is used to separate the removed sprue and the removal equipment itself. In the moment when the sprue is cut or knocked off, there may be splashes or impact forces, and the structure can effectively block these splashes or direct impacts, thereby protecting the equipment from being damaged. As the runner is usually larger and more solid than the sprue, the impact force generated during removal is also larger. The design of the runner anti-throwing structure is to cope with the above situation, i.e. to separate the removed runner and the removal equipment, so as to prevent the equipment from being damaged.
[0047] Case one, the case that the sub-frame sprue runner removal equipment is used to remove the sprue of the sub-frame, can be seen from Figures 3-5 .
[0048] The pouring basin anti-punching structure comprises a pouring basin flow divider 110, a pouring basin flow divider baffle 111 and a pouring basin support 114; the pouring basin support 114 is used to connect the lower frame body 102 of the sub-frame pouring basin runner removal device to support the pouring basin flow divider baffle 111 and the pouring basin flow divider 110; the pouring basin flow divider baffle 111 is obliquely installed on the pouring basin support 114 to make the removed pouring basin slide along the pouring basin flow divider baffle 111, and the pouring basin flow divider baffle 111 comprises a first opening for the passage of the band saw blade 108 of the sub-frame pouring basin runner removal device; the pouring basin flow divider 110 is located on the side of the pouring basin flow divider baffle 111 close to the band saw blade 108, and the pouring basin flow divider 110 comprises a second opening corresponding to the first opening for the passage of the band saw blade 108.
[0049] The pouring basin support 114 is the supporting basis of the entire anti-punching structure and is connected to the lower frame body 102 of the sub-frame pouring basin runner removal device. The main function of the pouring basin support 114 is to provide stable support to ensure that the pouring basin flow divider baffle 111 and the pouring basin flow divider 110 can be firmly installed thereon and maintain a stable position during the removal of the pouring basin. The pouring basin flow divider baffle 111 is obliquely installed on the pouring basin support 114, and the oblique design helps the removed pouring basin to slide along the baffle to avoid accumulation on the equipment or cause safety hazards. In addition, the first opening is designed on the flow divider baffle to allow the band saw blade 108 of the sub-frame pouring basin runner removal device to pass through. The band saw blade 108 is the main tool for removing the pouring basin and needs to be accurately cut under the guidance of the flow divider baffle.
[0050] The pouring basin flow divider 110 is located on the side of the pouring basin flow divider baffle 111 close to the band saw blade 108 and closely cooperates with the flow divider baffle. The second opening is designed on the flow divider to correspond to the first opening on the flow divider baffle, and is also designed to allow the band saw blade 108 to pass through. The main function of the flow divider is to further guide the band saw blade 108 to ensure accurate cutting of the pouring basin and prevent the splashing or impact of the fragments generated during the cutting process.
[0051] During the removal of the sub-frame pouring basin, the sub-frame is placed on the equipment, and the band saw blade 108 cuts the pouring basin. Due to the oblique design and opening guidance of the flow divider baffle and the flow divider, the cut-down pouring basin fragments will slide along the flow divider baffle, avoiding potential threats to the equipment and operators. At the same time, the solid structure of the flow divider and the flow divider baffle can effectively block and disperse the impact force generated during the cutting process to protect the equipment from damage.
[0052] Optionally, the pouring basin flow splitter 110 is rectangular pyramid-shaped with smooth surfaces. The rectangular pyramid-shaped structure has higher stability when subjected to impact forces. Its wider base provides better support area, ensuring that the flow splitter does not sway or tip over during the cutting process. The inclined surface design of the rectangular pyramid shape can more effectively guide the cut-off pouring basin fragments to slide off. When the band saw blade 108 cuts the pouring basin, the fragments will be pushed to the inclined surface of the flow splitter and slide down along the inclined surface to the ground or a collection container, avoiding the accumulation or splashing of fragments on the equipment. Moreover, the rectangular pyramid-shaped flow splitter, occupying the same space, can provide a longer inclined surface length, thereby increasing the sliding distance of the fragments and reducing the contact area of the fragments with the equipment during the sliding process, further reducing the potential damage to the equipment. In addition, the rectangular pyramid-shaped flow splitter has a regular shape and is easy to manufacture by casting, forging or mechanical processing, etc. At the same time, its compact structure facilitates connection and installation with the pouring basin support 114 and the flow splitter baffle.
[0053] Optionally, the pouring basin anti-impact structure further comprises a pouring basin hinge 112 and a pouring basin jacking cylinder 113; the pouring basin hinge 112 is used to connect the side of the pouring basin flow splitter baffle 111 away from the band saw blade 108 and the pouring basin support 114; the first end of the pouring basin jacking cylinder 113 is connected to the side of the pouring basin flow splitter baffle 111 close to the band saw blade 108, and the second end of the pouring basin jacking cylinder 113 is connected to the lower frame 102; the pouring basin jacking cylinder 113 is used to drive the pouring basin flow splitter baffle 111 to move around the pouring basin hinge 112 as the center.
[0054] The pouring basin hinge 112 is a key component that connects the side of the pouring basin flow splitter baffle 111 away from the band saw blade 108 and the pouring basin support 114. It allows the pouring basin flow splitter baffle 111 to swing or rotate within a certain range. Through the connection of the hinge, the pouring basin flow splitter baffle 111 can adjust its inclination angle or position when needed, and can shake off the removed pouring basin by swinging, and can also adapt to pouring basins of different sizes and shapes.
[0055] The pouring basin jacking cylinder 113 is usually composed of a cylinder body, a piston, a piston rod and other components. One end (i.e. the first end) is connected to the side of the pouring basin flow splitter baffle 111 close to the band saw blade 108, and the other end (i.e. the second end) is connected to the lower frame 102 of the device. The pouring basin jacking cylinder 113 drives the pouring basin flow splitter baffle 111 to move around the pouring basin hinge 112 as the center through the reciprocating motion of the piston. When the piston rod of the pouring basin jacking cylinder 113 extends, it pushes the pouring basin flow splitter baffle 111 to move upwards or forwards (the specific moving direction depends on the installation position of the cylinder and the arrangement of the hinge); when the piston rod retracts, the pouring basin flow splitter baffle 111 will move downwards or backwards accordingly.
[0056] During the process of removing the runner, the runner lifting cylinder 113 will work according to the preset program or the instructions of the operator. When the cylinder rod of the runner lifting cylinder 113 extends or retracts, it will drive a series of components (including the runner distributor 110 and the runner distributor baffle 111, etc.) to move in a circular motion around the runner hinge 112 as the center. Optionally, the range of the circular motion is limited within 35° to ensure that the components do not interfere with each other or exceed the preset working range during the movement.
[0057] In one possible implementation, as shown in Figure 5 , the runner anti-impact structure further comprises a runner swing arm 116 and a runner translation cylinder 115; the runner swing arm 116 is located on the extension line of the runner distributor 110, and the side of the runner swing arm 116 away from the runner distributor 110 is connected to the lever end of the runner translation cylinder 115 through the third opening on the runner distributor baffle 111; the runner translation cylinder 115 is used to drive the lever end to move, so as to drive the runner swing arm 116 to swing like a windshield wiper.
[0058] The runner swing arm 116 is designed to be located on the extension line of the runner distributor 110. The swing arm can effectively guide the falling of the cut-off runner fragments. The side of the swing arm away from the runner distributor 110 is connected to the third opening on the runner distributor baffle 111 in a certain way (such as a hinge or a pin shaft) to swing under the action of the translation cylinder. The runner translation cylinder 115 is an actuator that can provide linear reciprocating motion. The lever end of the runner translation cylinder 115 is connected to the runner swing arm 116, and the cylinder rod is extended and retracted to drive the lever end to move, thereby driving the swing arm to swing.
[0059] For example, during the process of removing the runner, the runner translation cylinder 115 will work according to the preset program or the instructions of the operator. When the cylinder rod of the runner translation cylinder 115 extends, it will push the runner swing arm 116 to swing through the lever end; when the cylinder rod retracts, the swing arm will return to the original position accordingly. The swinging motion can optimize the falling path of the runner.
[0060] The pouring and sprue anti-impact structure is designed to cope with the high-speed inertia and strong impact force generated by the removed pouring gate and sprue during the high-speed operation of the band saw blade 108, which can effectively protect the band saw blade 108 from damage. The pouring and sprue shunt baffle 111 and the pouring and sprue shunt block 110 can work cooperatively with the upper saw belt tensioning device to reduce the empty stroke suspension height of the band saw blade 108, reduce the transverse impact force on the saw blade during the removal of the pouring gate and sprue, and significantly improve the rigidity of the cutting contact surface of the annular band saw blade 108. It ensures that the band saw blade 108 performs the removal work of the pouring gate and sprue of the sub-frame in the optimal operating area, thereby realizing the continuous production of the workshop site.
[0061] Case two, the pouring and sprue runner removal equipment for the removal of the pouring gate of the sub-frame can be seen from Figure 6 and Figure 7 .
[0062] The pouring gate anti-impact structure includes a pouring gate shunt block 120 and a pouring gate shunt baffle 121. The pouring gate shunt baffle 121 is obliquely installed on the lower frame body 102 of the pouring and sprue runner removal equipment for the sub-frame, so that the removed pouring gate slides along the pouring gate shunt baffle 121. The pouring gate shunt baffle 121 includes a fourth opening for the band saw blade 108 of the pouring and sprue runner removal equipment for the sub-frame to pass through. The pouring gate shunt block 120 is located on the side of the pouring gate shunt baffle 121 close to the band saw blade 108. The pouring gate shunt block 120 includes a fifth opening corresponding to the fourth opening, and the fifth opening is used for the band saw blade 108 to pass through.
[0063] The main function of the pouring gate shunt baffle 121 is to guide the removed pouring gate part to slide along a specific path, thereby avoiding the removed pouring gate directly impacting or interfering with the operation of the band saw blade 108. The pouring gate shunt baffle 121 is obliquely installed on the lower frame body 102 of the pouring and sprue runner removal equipment for the sub-frame. The oblique design helps the pouring gate part to slide smoothly and reduces the opportunity to contact the saw blade. The pouring gate shunt baffle 121 is provided with a fourth opening, which is a passage designed for the band saw blade 108 to ensure that the saw blade can smoothly pass through the baffle and continue its cutting task.
[0064] The pouring gate shunt baffle 121 is connected quickly and stably by inserting a hinge pin into the pouring gate hinge 122 reserved on the lower frame body 102. The connection mode of the hinge pin is convenient for installation and disassembly, which is conducive to the maintenance and replacement of the equipment. The pouring gate shunt block 120 is located on the side of the pouring gate shunt baffle 121 close to the band saw blade 108, which further ensures that the removed pouring gate part does not interfere with the operation of the saw blade, while providing additional support and protection. The pouring gate shunt block 120 is provided with a fifth opening corresponding to the fourth opening on the pouring gate shunt baffle 121, which together forms a passage for the band saw blade 108. It ensures that the saw blade will not be hindered during the passage.
[0065] By combining the design of the runner diverter block 120 and the runner diverter baffle 121, the runner anti-punching structure can effectively guide the removed runner part, reducing the potential threat of the removed runner to the band saw blade 108. At the same time, the structure also ensures the smooth operation of the saw blade and the easy maintenance of the equipment through the reserved opening and the hinge connection method. Further, it improves the production efficiency, prolongs the service life of the band saw blade 108, and provides strong support for the runner removal work of the sub-frame sprue.
[0066] Optionally, the runner diverter block 120 is a rectangular pagoda shape with a transition shoulder. The levels are distinct, which plays a role in avoiding the long volume of the runner from scratching the equipment band saw blade 108. The diverter effect is obvious for the runner entity that is divided multiple times and has a long volume.
[0067] The runner diverter block 120 is designed as a rectangular pagoda shape with distinct transition shoulders. The transition shoulders not only provide a solid structural support for the runner diverter block 120, but also make it visually layered, making it easy to observe and identify. The runner diverter block 120 with transition shoulders can effectively avoid the long volume of the runner from scratching the equipment band saw blade 108 during removal. When the runner is cut and slides along the runner diverter baffle 121, the transition shoulder can provide a smooth transition path to guide the runner to bypass the saw blade instead of colliding with the saw blade.
[0068] The runner diverter block 120 of the above design is suitable for dealing with runner entities that are divided multiple times and have a long volume. In actual operation, long runner entities are often difficult to handle due to their large volume and irregular shape. However, the runner diverter block 120 with a rectangular pagoda shape and transition shoulders can effectively guide the runner entity to a safe position through its unique diverter effect, thereby avoiding potential damage to the band saw blade 108.
[0069] In one possible implementation, the runner anti-punching structure further includes a runner hinge 122 and a runner jacking cylinder 123; the runner hinge 122 is used to connect the side of the runner diverter baffle 121 away from the band saw blade 108 and the lower frame 102; the first end of the runner jacking cylinder 123 is connected to the side of the runner diverter baffle 121 close to the band saw blade 108, and the second end of the runner jacking cylinder 123 is connected to the lower frame 102, and the runner jacking cylinder 123 is used to drive the runner diverter baffle 121 to rotate around the runner hinge 122 as the center.
[0070] The gate hinge 122 is a key component that connects the gate splitter baffle 121 to the side of the band saw blade 108 and the lower frame 102. It allows the gate splitter baffle 121 to rotate or swing within a certain range, so as to adapt to different working requirements. The gate hinge 122 is usually installed at a proper position of the lower frame 102, so as to ensure that the gate splitter baffle 121 can be connected and rotated smoothly and reliably.
[0071] The gate lifting cylinder 123 is the main power source for driving the gate splitter baffle 121 to move. By extending and retracting its cylinder rod, the gate splitter baffle 121 is driven to rotate around the gate hinge 122, so as to realize dynamic adjustment of the gate splitter. The first end (cylinder body part) of the gate lifting cylinder 123 is connected to the reserved mounting support of the lower frame 102, and the second end (cylinder rod part) is connected to the gate splitter baffle 121.
[0072] When the cylinder rod of the gate lifting cylinder 123 extends and retracts, it can drive the gate splitter block 120 and the gate splitter baffle 121 to perform circular motion around the gate hinge 122 within a range of about 30°. By introducing the two key components of the gate hinge 122 and the gate lifting cylinder 123, the gate anti-punching structure can more easily shake off the removed gate.
[0073] In a possible implementation, the connection structure between the gate anti-punching structure and the riser anti-punching structure and the subframe riser and gate removal device is universal.
[0074] In the above possible implementation, the gate anti-punching structure and the riser anti-punching structure adopt the same connection structure as the subframe riser and gate removal device. That is, the two anti-punching structures can be conveniently installed on the same device without the need to design different connection components for each structure. The universality not only simplifies the installation and maintenance process of the device, but also reduces the manufacturing cost. In order to realize the universality, the lower frame 102 is designed to have multiple reserved mounting points. Specifically, four mounting threaded holes are reserved on the outside of the lower frame 102, which are used to connect the riser supports 114. The riser supports 114 are key components for supporting the riser anti-punching structure, and by fixing these supports on the lower frame 102, it can be ensured that the riser anti-punching structure works stably and reliably.
[0075] On the side and top of the lower frame 102, mounting supports for the riser lifting cylinder 113 and the sprue lifting cylinder 123, and the sprue hinge 122 are reserved respectively. The supports provide stable support points for the cylinders and hinges, ensuring stability and reliability during operation. By reserving these mounting points and supports on the lower frame 102, the riser anti-impact structure and the sprue anti-impact structure can be conveniently installed and fixed. This improves the flexibility and adaptability of the equipment, making the entire system more compact and efficient. In practical applications, the universal connection structure can greatly simplify the installation and debugging process of the equipment, reducing the difficulty of operation and maintenance costs. At the same time, since standardized connection components and installation methods are used, the interchangeability and maintainability of the equipment can also be improved, providing convenience for long-term use and maintenance of the equipment.
[0076] Optionally, the riser anti-impact structure corresponds to a riser anti-impact system, and the sprue anti-impact structure corresponds to a sprue anti-impact system.
[0077] The riser anti-impact system can include the riser anti-impact structure and all related control, monitoring and auxiliary equipment. For example, the system can include a cylinder control system for driving the anti-impact structure, sensors for monitoring the riser removal process, and software algorithms for adjusting and optimizing system performance, etc. The entire system works together to ensure the safety and efficiency of the riser removal process. The sprue anti-impact system is similar to the riser anti-impact system and can include the sprue anti-impact structure and all related control, monitoring and auxiliary equipment. The system can include a cylinder control system, sensors, software algorithms, etc., to ensure the safety and efficiency of the sprue removal process.
[0078] In combination with the above description, it is realized that the same subframe riser and sprue removal equipment can be connected with different anti-impact structures, thereby realizing the reuse of a single device and reducing production costs. Next, taking the process of removing the riser and sprue of a subframe with a single device as an example.
[0079] On the subframe riser and sprue removal equipment, the sprue saw belt anti-impact device (i.e. the sprue anti-impact structure) is first installed, thereby ensuring that the sprue part does not splash and hit the equipment or operators when the belt saw blade 108 is rotating at high speed and cutting off the sprue, providing safety protection.
[0080] Through the touch screen window on the external electrical cabinet, the user needs to set the initialization parameters, including the model of the subframe, the sprue options, etc. Then, the tensioning pressure of the belt saw blade 108 for cutting off the sprue is set to ensure that the saw blade can maintain stability when rotating at high speed and achieve the expected cutting effect. At the same time, the rotation speed of the belt saw blade 108 for cutting off the sprue also needs to be set. According to the material of the subframe and the size of the sprue, selecting the appropriate rotation speed can improve the cutting efficiency and cutting quality.
[0081] After the parameter setting is completed, the device start button is pressed, and the subframe sprue runner removal device enters the standby state, waiting for the next operation of the user.
[0082] After the device is started, the program control power motor 105, the upper pulley 106, the lower pulley 107, and the band saw blade 108 of the subframe sprue runner removal device rotate at high speed according to the set sprue removal parameters. The user operates the manipulator to place the subframe whose runner needs to be removed in front of the subframe sprue runner removal device, and smoothly pushes it into the working area of the band saw blade 108. According to the process flow of removing the subframe sprue runner, the subframe runner is removed one by one, and at the same time, the cylinder rod of the sprue jacking cylinder 123 continuously extends and retracts, driving the sprue distribution block 120 and the sprue distribution baffle 121 to make reciprocating circular motion within 30° around the sprue hinge 122, cleaning away the removed runner. The cutting aluminum chips are discharged through the aluminum chip discharge port 109.
[0083] After the subframe runner removal is completed, the user operates the manipulator to smoothly remove the subframe whose runner has been removed from the working area of the band saw blade 108, and temporarily stores it on one side for stacking. Continue to place the subframe whose runner needs to be removed in front of the subframe sprue runner removal device for continuous, batch, and stable production.
[0084] After the subframe runners of this batch have been removed, the subframe sprue runner removal device is stopped. By simple disassembly and hinge pin connection, the sprue sawing belt anti-smashing device (sprue anti-smashing structure) is installed on the subframe sprue runner removal device. Through the touch screen window on the external electrical cabinet, the subframe model initialization setting and the sprue option setting are set, the parameters such as the tensioning pressure of the sprue band saw blade 108 and the rotation speed of the sprue band saw blade 108 are set, and the device start button is pressed.
[0085] The program control power motor 105, the upper pulley 106, the lower pulley 107, and the band saw blade 108 of the subframe sprue runner removal device rotate at high speed according to the set sprue removal parameters.
[0086] The user operates the manipulator to place the subframe whose runner has been removed and whose sprue needs to be removed in front of the subframe sprue runner removal device, and smoothly pushes it into the working area of the band saw blade 108. According to the process flow of removing the subframe sprue runner, the subframe sprue is removed one by one, and at the same time, the extension and retraction of the cylinder rod of the sprue jacking cylinder 113 drives the sprue distribution block 110, the sprue distribution baffle 111, the sprue translation cylinder 115, and the sprue swing arm 116 to make circular motion within 35° around the sprue hinge 112.
[0087] When the riser lifting cylinder 113 extends, the riser translation cylinder 115 extends, driving the riser swing arm 116 to swing. The removed sprue and riser are cleaned. When the riser lifting cylinder 113 retracts, the riser translation cylinder 115 retracts, driving the riser swing arm 116 to swing back to its original position. The cut aluminum chips are discharged through the aluminum chip discharge port 109. After the removal of the sprue and riser of the subframe is completed, the sprue, riser, and runner produced during the integrated casting of the subframe are removed and cleaned, and the work is completed.
[0088] During the entire operation, the user needs to closely monitor the running state of the equipment and the cutting effect to ensure that the equipment operates within a safe parameter range. When placing and removing the subframe, the user needs to ensure smooth and rapid movements to avoid unnecessary damage to the equipment or work area. When cleaning the cut aluminum chips, the user needs to wear appropriate protective equipment to avoid injury to the skin or eyes caused by cut aluminum chips. When the equipment is shut down or being maintained, the user needs to follow the safety operating procedures of the equipment to ensure the safety and reliability of the equipment.
[0089] For example, the device program system can monitor the speed of the power motor 105 in real time to ensure that the motor operates within the preset parameter range. If the motor speed is abnormal, the system can immediately issue an alarm message to remind the user to check and maintain. The system can also monitor the air pressure values used in the equipment, including the air pressure of the runner lifting cylinder 123 and the riser lifting cylinder 113. By monitoring the air pressure values, the system can ensure that the cylinder can provide sufficient power when needed, while avoiding damage to the equipment caused by excessively high or low air pressure. The system can monitor various set values of the equipment, including the tensioning pressure and rotation speed of the band saw blade 108. By comparing with the actual running values, the system can determine whether the equipment operates according to the preset parameters, thereby ensuring the cutting effect and stability of the equipment. The device program system has a perfect alarm mechanism, which can monitor the running state of the equipment in real time and issue an alarm message when an abnormality occurs. These alarm messages can include motor failure, air pressure anomaly, saw blade breakage, etc., helping the user to discover and solve problems in a timely manner.
[0090] In addition, the system can record the tensioning pressure of the band saw blade 108 each time it is used, which helps to analyze the wear and tear of the saw blade and the cutting effect. By comparing the cutting effect under different tensioning pressures, the tensioning pressure setting of the saw blade can be optimized to improve the cutting efficiency and the service life of the saw blade. The system can record the number of saw cuts of the band saw blade 108 during the removal of the sprue and runner. This helps to evaluate the cutting capacity and service life of the saw blade, so as to reasonably arrange the replacement and maintenance plan of the saw blade. The system can also record the number of sub-frame products produced after each saw cut is completed. This helps to calculate the production capacity and production efficiency of the equipment, providing data support for production planning and scheduling. Through the recording and analysis of the above data, the system can calculate the proportion of a single band saw blade 108 and the sub-frame product. This helps to evaluate the use cost and production benefit of the saw blade, providing a basis for the cost control and decision-making of the enterprise.
[0091] Optionally, the equipment program system can store and manage the above-mentioned monitored and recorded data. These data can be saved in the internal memory of the equipment, or transmitted to a remote server for backup and storage through network connection. Through the stored data, the system can realize the traceability function of information. When it is necessary to query the equipment running status, saw blade usage or product quality information in a certain period of time, the system can quickly provide accurate data support.
[0092] Further, by real-time monitoring of the running state and cutting effect of the equipment, the system can timely issue an alarm information when an abnormality occurs. This helps users to discover and solve problems in time, avoiding the generation of bad waste products. The system can also analyze and mine the stored data to find potential fault hidden dangers and quality problems. Through data analysis, the system can issue early warning information in advance to remind users to take preventive and maintenance measures.
[0093] In summary, the technical scheme provided by the utility model separates the removed sprue and runner from the sub-frame sprue and runner removal equipment, and the removed runner from the sub-frame sprue and runner removal equipment, respectively, through the sprue anti-punching structure and the runner anti-punching structure, thereby reducing the possibility of the band saw blade of the sub-frame sprue and runner removal equipment being punched. Moreover, the universality of the sprue anti-punching structure and the runner anti-punching structure enables the sprue removal work and the runner removal work to be performed on the same sub-frame sprue and runner removal equipment, thereby reducing the production cost.
