Description

Technical Field

[0001] The invention relates to the technical field of gradual grinding, in particular to a casting riser grinding device. Background Art

[0002] In the foundry industry, the production of castings is a complex and delicate process, and the presence of risers is an unavoidable part of this process. Riser refers to the component used to guide the molten metal into the mold and remove gases during the casting process. It includes the runner (the channel that guides the molten metal into the mold) and the riser (which is used to contain excess molten metal and remove gases from the mold). Once the molten metal cools and solidifies, these risers become redundant components of the casting and need to be removed or trimmed during subsequent processing to facilitate the final use of the product.

[0003] The primary purpose of polishing the riser is to remove excess material from the casting surface, resulting in a smoother and more aesthetically pleasing surface and ensuring that the casting's dimensional accuracy meets design requirements. Polishing also helps improve casting quality by preventing performance degradation caused by residual riser residue. A good polishing process not only enhances the product's appearance but also its mechanical properties, making it particularly important for applications requiring stringent surface finish requirements.

[0004] However, in traditional casting production, the polishing of risers is often performed manually. Workers typically use handheld grinders to meticulously polish the risers on castings. While this method can achieve certain results, it also has significant drawbacks. First, manual polishing is inefficient, especially when faced with large-scale production tasks, and cannot meet the needs of rapid production. Second, labor costs are high, and with the continuous rise in labor costs, this method is increasingly burdened by costs. More importantly, the polishing process generates a large amount of metal dust, which not only pollutes the environment but also poses a potential threat to the health of operators. Long-term exposure to this dust can lead to occupational diseases such as respiratory illnesses. Summary of the Invention

[0005] The purpose of the present invention is to provide a casting riser grinding device, which adopts automated equipment to replace manual work for casting riser grinding, thereby improving efficiency, reducing labor costs, and avoiding damage to the human body caused by manual work.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0008] The lower end of each clamping disc is connected to a magnetic iron-absorbing disc that can move up and down relative to it, the edge of the lower end of each rotating plate is downwardly provided with multiple connecting shafts, the edge of each magnetic iron-absorbing disc is provided with multiple connecting slip rings that are slidably connected to the corresponding connecting shafts, the edge of the lower end of each connecting shaft is provided with a limiting ring outwardly, and a supporting spring of the corresponding connecting shaft is provided between each limiting ring and the corresponding connecting slip ring. A plurality of rotating motors corresponding to the positions of the magnetic iron-absorbing discs are upwardly installed in the lower part of the frame body, and the power output shaft of each rotating motor is upwardly connected to an electromagnetic suction cup, and each electromagnetic suction cup is located below the magnetic iron-absorbing disc;

[0009] The mounting platform is provided with a scanning frame upwardly in the transmission belt, the scanning frame corresponds to the position of one of the rotating motors, and the scanning frame is provided with a three-dimensional laser scanner outwardly toward the conveying plate;

[0010] The mounting platform is provided with a first mounting bracket upward in the transmission belt, the first mounting bracket corresponds to the position of one of the rotating motors, a first horizontal sliding bracket is provided on the upper end of the first mounting bracket outwardly toward the direction of the conveying plate, a first sliding mounting platform is slidably connected to the first horizontal sliding bracket, a first telescopic motor for driving the first sliding mounting platform to slide is installed on the first horizontal sliding bracket, a first electric hydraulic cylinder is vertically installed on the first sliding mounting platform, a cutting motor is installed at the lower end of the first electric hydraulic cylinder, and a horizontally arranged cutting saw blade is connected to the power output shaft of the cutting motor;

[0011] The mounting platform is provided with a second mounting bracket upward in the transmission belt, and the second mounting bracket corresponds to the position of one of the rotating motors. A second horizontal sliding bracket is provided at the upper end of the second mounting bracket outward toward the conveying plate, and a second sliding mounting platform is slidably connected to the second horizontal sliding bracket. A second telescopic motor for driving the second sliding mounting platform to slide is installed on the second horizontal sliding bracket, and a second electric hydraulic cylinder is vertically installed on the second sliding mounting platform. A vertical grinding motor is installed at the lower end of the first electric hydraulic cylinder, and a power output shaft of the vertical grinding motor is connected to a horizontally arranged horizontal grinding disc.

[0012] By adopting the above technical solution, before grinding the casting riser, the casting is first hoisted onto the clamping disc, and a rectangular insert is inserted into the drive socket to rotate the threaded drive shaft, driving the threaded sleeve to move and drive the movable clamp to clamp the lower edge of the casting. Then the casting moves on the clamping disc along with the transmission belt;

[0013] When it moves to the position of the 3D laser scanner, the electromagnet suction cup below is energized to generate magnetic attraction, which moves the magnetic suction cup downward and compresses the support spring. At this time, the clamping disc can be driven by the rotating motor to drive the casting to rotate. The 3D laser scanner is used to perform 3D scanning and modeling of the casting, and the dimensions are compared with the standard model to determine the positions of the pouring nozzle and the flash. After the scanning is completed, the rotation position of the casting is fixed, the electromagnet is powered off, and the magnetism is lost. The magnetic suction cup is reset under the action of the support spring, and the casting continues to move with the transmission belt.

[0014] When the casting moves to the first mounting position, the electromagnet suction cup below is energized to generate magnetic attraction to the magnetic suction cup, fixing the position of the casting to prevent it from rotating during cutting. Then, according to the scanning results, the first telescopic motor drives the cutting saw blade to descend to a suitable height, and the first telescopic motor drives the cutting saw blade to gradually move toward the gate. The cutting motor drives the cutting saw blade to rotate and cut off the gate. Then, the rotary motor drives the casting to rotate, so that the riser is close to the cutting saw blade, and the riser is cut off again.

[0015] When the casting moves to the second mounting position, the electromagnet suction cup below is energized to generate magnetic attraction to the magnetic suction cup, fixing the position of the casting to prevent it from rotating during grinding. Then, according to the scanning results, the second telescopic motor drives the horizontal grinding disc to descend to the appropriate height, and the second telescopic motor drives the horizontal grinding disc to gradually move toward the gate. The vertical grinding motor drives the horizontal grinding disc to gradually grind the cutting position of the pouring gate smooth. After completion, the casting continues to move with the transmission belt. Finally, on the other side of the transmission belt, the movable clamp is released, and the polished casting is lifted off the clamping disc to complete the grinding of a casting.

[0016] The present invention is further configured as follows: the mounting platform is provided with a horizontal slide rail in the direction of the conveying plate in the transmission belt, and a horizontal conveying motor is installed at one end of the horizontal slide rail, and a horizontal screw rod connected to a power output shaft of the horizontal conveying motor is rotatably connected in the horizontal slide rail, and the horizontal slide rail is slidably connected to a horizontal screw rod sleeve cooperating with the horizontal screw rod, and a vertical slide rail is upwardly provided with a vertical conveying motor, and a vertical slide rail is installed at the lower end of the vertical slide rail.

[0017] By adopting the above technical solution, when the casting moves to the position of the horizontal grinding motor, the electromagnet suction cup below is energized to generate magnetic attraction to the magnetic suction cup, and the horizontal conveying motor drives the vertical slide rail to move along the horizontal slide rail with the horizontal screw sleeve. The vertical conveying motor drives the horizontal grinding motor to move along the vertical slide rail with the vertical screw sleeve, so that the conical grinding head is close to the flash of the casting, and the horizontal grinding motor drives the conical grinding head to rotate at high speed to grind the flash of the casting. During the grinding process, the rotating motor drives the casting to rotate continuously, and the horizontal conveying motor cooperates to drive the conical grinding head forward and backward to complete the grinding of the casting flash, thereby realizing the grinding of the casting flash.

[0018] The present invention is further configured as follows: an intelligent recognition camera is installed on the upper end of the vertical slide rail facing outward toward the conveying plate.

[0019] The present invention is further configured as follows: each driving wheel is a gear, the transmission belt is a gear belt meshing with the driving wheels, and the power output shaft of the driving motor is connected to one of the driving wheels.

[0020] The present invention is further configured as follows: the frame is provided with a runway-shaped inner track outside the transmission belt, the frame is provided with a runway-shaped outer track outside the inner track, and the lower end of the conveying plate is equipped with two positioning rollers that are respectively connected to the inner track and the outer track in a rolling manner.

[0021] The present invention is further configured as follows: the upper end of each clamping disc is provided with a plurality of clamping rails arranged from the center of the circle outward, each clamping rail is rotatably connected to a threaded drive shaft, the outer end of each threaded drive shaft passes through the corresponding clamping rail and is provided with a drive head, each drive head is provided with a non-circular drive socket, each clamping rail is slidably connected to a threaded sleeve threadedly connected to the corresponding threaded drive shaft, and each movable clamp is provided at the upper end of the corresponding threaded sleeve.

[0022] The present invention is further configured such that: the cross section of the driving socket is rectangular.

[0023] The present invention is further configured such that the edge of each magnetic iron-absorbing disk is connected to the corresponding connecting slip ring via an upwardly bent bending strip.

[0024] The present invention is further configured as follows: a linear motor is provided outwardly from the free end of the first horizontal sliding frame, the free end of the linear motor is connected to the side of the frame through a connecting frame, a mounting bar is provided downwardly of the mover of the linear motor, and a transfer electromagnet is installed on one side of the mounting bar.

[0025] By adopting the above technical solution, before cutting the pouring riser, the linear motor drives the transfer electromagnet to move to the pouring riser and generates magnetism when powered on. When the pouring riser or the pouring riser is cut off, it is sucked by the transfer electromagnet and then transported to the other end by the linear motor. After the power is cut off and the magnetism is lost, the pouring riser falls off, and the cut pouring riser can be recycled to prevent the pouring riser from falling and accumulating on the device.

[0026] The present invention is further configured as follows: the frame is provided with a material storage trough below the free end of the linear motor.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] First, the device of the present invention realizes the full process automation from casting loading, positioning, scanning, cutting to polishing through automated assembly line design, reduces the need for manual intervention, and significantly improves production efficiency. Compared with traditional manual polishing methods, the device reduces dependence on manpower, reduces labor costs, and reduces errors caused by manual operation.

[0029] Secondly, the excess metal flakes (flash) that appear at the edges or joints of the casting are caused by the overflow of molten metal from the mold during the casting process. The present invention can also automatically polish the flash at the edges or joints of the casting through the conical grinding head, without the need for manual operation, thereby improving production efficiency.

[0030] Third, the present invention uses a three-dimensional laser scanner to perform three-dimensional modeling and compare it with a standard model, which can accurately identify the positions of the pouring spout and flash, ensure the accuracy of cutting and grinding, and improve the processing quality of the casting.

[0031] Fourthly, through adjustable sliding mechanisms (such as horizontal sliding frames, vertical slide rails, etc.) and multi-angle grinding tools (such as conical grinding heads), it can flexibly cope with castings of different shapes and sizes and has strong adaptability.

[0032] Fifth, the present invention transfers the cut risers to the side by attracting them through a transfer electromagnet to prevent the risers from falling and accumulating on the device, so that the cut risers can be recycled.

[0033] Sixth, the present invention innovatively uses an electromagnet chuck to fix the casting, which can accurately control the rotation of the casting during the cutting and grinding process without affecting the movement of the casting with the transmission belt.

[0053] The mounting platform 2 is provided with a horizontal slide rail 48 in the direction of the conveyor plate 6 within the transmission belt 4. A horizontal conveying motor 49 is mounted on one end of the horizontal slide rail 48. A horizontal screw rod 50 connected to the power output shaft of the horizontal conveying motor 49 is rotatably connected to the horizontal slide rail 48.

When grinding the burrs, the size and position of the burrs can be accurately judged through AI video recognition technology, which makes it easier to grind the burrs.

[0054] Working principle: Before grinding the casting riser, first hoist the casting onto the clamping disc 11, insert a rectangular insert into the drive socket 15, and rotate the threaded drive shaft 13 to drive the threaded sleeve 16 to move and drive the movable clamp 17 to clamp the lower edge of the casting. Then the casting moves on the clamping disc 11 along with the transmission belt 4.

[0055] When it moves to the position of the three-dimensional laser scanner 28, the electromagnet suction cup 25 below is energized to generate magnetic attraction to the magnetic iron-absorbing disc 18, which moves downward and compresses the support spring 23. At this time, the clamping disc 11 can be driven by the rotating motor 24 to drive the casting to rotate. The three-dimensional laser scanner 28 is used to perform three-dimensional scanning and modeling of the casting, and the size is compared with the standard model to determine the position of the pouring head and the flash. After the scanning is completed, the rotation position of the casting is fixed, the electromagnet is powered off, and the magnetism is lost. Under the action of the support spring 23, the magnetic iron-absorbing disc 18 is reset, and then the casting continues to move with the transmission belt 4.

[0056] When the casting moves to the position of the first mounting bracket 29, the electromagnet suction cup 25 below is energized to generate magnetic attraction to the magnetic suction cup 18, fixing the position of the casting to prevent it from rotating during cutting. Then, according to the scanning result, the first telescopic motor 32 drives the cutting saw blade 35 to drop to a suitable height, and the first telescopic motor 32 drives the cutting saw blade 35 to gradually move toward the gate. The cutting motor 34 drives the cutting saw blade 35 to rotate and cut off the gate. Then, the rotating motor 24 drives the casting to rotate so that the riser is close to the cutting saw blade 35 and the riser is cut off again. Before cutting, the linear motor 36 drives the transfer electromagnet 39 to move to the gate or riser and energizes it to generate magnetism. When the gate or riser is cut off, it is attracted by the transfer electromagnet 39 and then transported to the other end by the linear motor 36. After the power is turned off and the magnetism is lost, the gate or riser falls into the storage trough 40. After completion, the casting continues to move with the transmission belt 4;

[0057] When the casting moves to the position of the second mounting bracket 41, the electromagnet suction cup 25 below is energized to generate magnetic attraction to the magnetic suction cup 18, fixing the position of the casting to prevent it from rotating during grinding. Then, according to the scanning results, the second telescopic motor 44 drives the horizontal grinding disc 47 to descend to a suitable height. The second telescopic motor 44 drives the horizontal grinding disc 47 to gradually move toward the gate. The vertical grinding motor 46 drives the horizontal grinding disc 47 to gradually grind the cutting position of the pouring riser to be smooth. After completion, the casting continues to move with the transmission belt 4.

[0058] When the casting moves to the position of the horizontal grinding motor 56, the electromagnet suction cup 25 below is energized to generate magnetic attraction to the magnetic suction cup 18, and the horizontal conveying motor 49 drives the vertical slide rail 52 to move along the horizontal slide rail 48 with the horizontal screw sleeve 51, and the vertical conveying motor 53 drives the horizontal grinding motor 56 to move along the vertical slide rail 52 with the vertical screw sleeve 55, so that the conical grinding head 57 is close to the flash of the casting, and the horizontal grinding motor 56 drives the conical grinding head 57 to rotate at a high speed to grind the flash of the casting. During the grinding process, the rotating motor 24 drives the casting to rotate continuously, and the horizontal conveying motor 49 cooperates to drive the conical grinding head 57 forward and backward to complete the grinding of the casting flash. After grinding is completed, the casting continues to move with the transmission belt 4;

[0059] Finally, on the other side of the transmission belt 4, the movable clamping block 17 is released, and the polished casting is lifted off the clamping disc 11 to complete the polishing of one casting.
