Description

Technical Field

[0001] The invention relates to the technical field of casting processing equipment, in particular to a casting excess material removal device. Background Art

[0002] Casting residue refers to the excess material or parts produced during the casting process. Casting residue usually varies depending on the requirements of the casting process and the needs of product design. Parts of casting residue that are too large, too thick, or do not meet the specifications need to be removed or trimmed to ensure the quality of the final product. At the same time, casting residue needs to be cut off for reuse. By cutting off casting residue, the reliability of the product can be improved.

[0003] In the existing technology, laser cutting is generally used to cut off the excess parts of castings. The casting is placed on a work platform for design and planning, and the position and shape to be cut are determined. According to the characteristics of the laser equipment and materials used, appropriate cutting parameters are selected. When starting cutting, the laser is aimed at the position to be cut so that it cuts along the established route. After the cutting is completed, the excess material is cooled and collected.

[0004] In actual operation, the use of laser cutting of casting residues will produce a heat-affected zone around the cutting line, which will cause deformation of the material and change the color of the material itself. Due to the insufficient depth of laser cutting and the slow cutting speed, for some thicker castings, multiple punching and multiple cutting passes may be required to reach the required cutting depth, thereby increasing the time required for cutting. In the process of laser cutting materials, the laser equipment does not have its own cooling device, and the casting needs to be cooled after cutting. Due to the long-term height, the material state of the casting itself is affected.

[0005] To this end, the existing technology provides some solutions, which include using a shearing machine to cut off the remaining material of the casting, placing the casting on a work platform, using a hydraulic system to power the shearing machine, and cooperating with the upper and lower knives to solve the problems of slow cutting speed and insufficient cutting depth. However, it fails to solve the problem of polishing the surface of the casting. At the same time, the casting is not cooled during the shearing process, which leads to a decrease in the product quality of the casting.

[0006] In view of this, in order to overcome the above technical problems, the present invention designs a casting excess material removal device to solve the above technical problems. Summary of the Invention

[0007] The object of the present invention is to provide a device for removing excess material from a casting, which improves the stability of removing excess material from a casting by intermittently switching the working state.

[0008] In order to achieve the above object, the present invention proposes the following technical solutions:

[0009] The present invention provides a casting waste material cutting device, which includes a hydraulic cylinder, a base, a shearing assembly, a grinding assembly, and an ejection assembly. A hydraulic cylinder is fixedly installed on the right side of the base, and a vertical plate is provided on the right side of the base. The hydraulic cylinder is fixedly installed at 1 / 2 of the vertical plate, thereby achieving uniform pressure application to avoid uneven pressure. The ejection rod of the hydraulic cylinder is connected to the shearing assembly, and a shearing assembly for protection is installed on the base near the hydraulic cylinder. The shearing assembly shears the casting waste material by cross-engaging with the left and right. When the operator is working, the casting waste material is cut off by the cross-engaging of the shearing assembly, thereby protecting the operator during the shearing process to avoid injuries to the personnel caused by the ejection of the casting waste material. The cylinder is connected to the shearing assembly, and a grinding assembly for intermittent clamping is installed above the shearing assembly. When the equipment is working, the shearing assembly does not shear the casting. When the casting with excess material passes through the grinding assembly, the grinding assembly will swing up and down, thereby removing the oxide film on the surface of the casting. When the casting to be sheared enters the shearing assembly, due to the large size of the casting, it shakes during the shearing process. At this time, the grinding assembly can clamp the casting and cool the casting at the same time, thereby cooling the casting during the shearing process, thereby removing the oxide film on the surface of the casting and clamping and cooling the casting during the shearing process.

[0010] A push-out assembly for assisting in cleaning the shearing assembly is installed below the polishing assembly. The push-out assembly is installed above the base plate. When the equipment is working, the casting with residual material is sheared. After a long period of work, the sheared castings will accumulate on the base, thereby causing the subsequent castings that need to be sheared to be unable to be sheared. The push-out assembly can push out the casting that has been sheared for the previous time after the shearing is completed, thereby avoiding the accumulation of castings that make it impossible to shear. While the push-out assembly is working, the residual material sheared off the base can be cleaned up, thereby realizing the pushing out of the sheared castings on the one hand and the cleaning of the residual material sheared on the workbench on the other hand.

[0011] The preferred shearing assembly includes a No. 1 blade, a No. 2 blade, a connecting column, a protective cover, a connecting spring and an extrusion head. A hydraulic cylinder for providing power is fixedly installed on the right side of the base, thereby being able to provide a greater shear force to thicker castings. The output end of the hydraulic cylinder is fixedly connected to a connecting column that changes the working state. The connecting column is U-shaped, and cylindrical protrusions that match the No. 1 blade and the No. 2 blade are respectively provided on both sides of the connecting column. A No. 1 blade is fixedly installed on one side of the connecting column. The No. 1 blade is trapezoidal, thereby achieving cutting of the remaining material of the casting. A sliding groove is provided at the place where the No. 1 blade cooperates with the connecting column. A No. 2 blade is fixedly installed on the other side of the connecting column. The No. 2 blade is rectangular, thereby achieving fixing of the casting during the cutting process. The No. 2 blade A sliding groove is provided at the place where the connecting column cooperates with the connecting column, so that when the connecting column moves left and right through the hydraulic cylinder, the No. 1 blade and the No. 2 blade can cross-engage and shear the casting. The upper ends of the No. 1 blade and the No. 2 blade are fixedly installed with a protective cover clamped by an auxiliary grinding assembly, so as to prevent the sheared casting residue from bursting out during the shearing process, thereby improving the safety of the equipment. The protective cover is divided into two parts, left and right, and the left and right parts of the protective cover are fixedly installed with connecting springs. An extrusion head for clamping is fixedly installed on the end of the connecting spring away from the protective cover. During the shearing process, the extrusion head will be close to both sides of the casting, so that the auxiliary grinding assembly can fix and clamp the casting during shearing, so as to avoid excessive pressure on the casting residue during shearing, which causes the casting to deflect.

[0012] Preferably, the extrusion head is used to clamp the polished casting through the connection spring and the protective cover. The length ratio of the extrusion head and the protective cover is 2:3, so that the polished surface of the casting can be clamped in conjunction with the polishing component during the shearing process to ensure the surface quality of the polished casting. When the length ratio is less than 2:3, the clamping range of the extrusion head on the polished casting surface is insufficient. In the shearing process, there is not enough clamping range and the casting deviates, causing the grinding block to damage the polished surface. When the length ratio is greater than 2:3, a smaller casting causes a gap between the protective cover and the casting when clamped. The sheared excess material pops out through the gap and causes damage to the operator, and the protective cover fails to play a protective role. The extrusion head is fixedly installed at 1 / 3-2 / 3 of the protective cover, so that the casting can be centrally clamped and fixed to avoid deviation.

[0013] Preferably, the grinding assembly includes electromagnets, air bags, a first moving plate, a second moving plate, sliding blocks, connecting rods, the base is slidably installed with a first moving plate for clamping near the first blade, the base is provided with a sliding groove for the sliding of the first moving plate, the lower end of the first moving plate is provided with a sliding block matched with the sliding groove, the base is slidably installed with a second moving plate for clamping near the second blade, the base is provided with a sliding groove for the sliding of the second moving plate, the lower end of the second moving plate is provided with a sliding block matched with the sliding groove, the first moving plate and the second moving plate can move with the movement of the shearing assembly when shearing, thereby achieving the fixing and clamping of the casting during shearing by the grinding assembly, avoiding the offset deformation of the casting due to excessive stress, the first moving plate and the second moving plate are both fixedly installed with air bags for cooling, thereby achieving the cooling of the casting during shearing to speed up the cooling speed of the casting, avoiding the deformation of the casting due to overheating expansion, the electromagnet is fixedly installed with a grinding surface at the end away from the moving plate, the electromagnet is always attached to the two sides of the casting, thereby achieving the removal of the oxidation film on the surface of the casting during transportation, avoiding the corrosion and rust of the casting surface due to the oxidation film, reducing the product quality of the casting, the right side of the first moving plate is fixedly installed with a first connecting rod matched with the shearing assembly, the right side of the second moving plate is fixedly installed with a first connecting rod matched with the shearing assembly, the first connecting rod and the second connecting rod are fixedly installed below the first moving plate and the second moving plate and matched with the pushing assembly, thereby achieving the clamping and fixing of the casting by the clamping assembly when the shearing assembly shears the excess material of the casting, and the pushing assembly can also push the workpiece after shearing is completed, the lower end of the connecting rod is provided with a sliding block matched with the sliding groove on the base.

[0014] Preferably, the electromagnet is fixedly installed with a grinding block for clamping at the end away from the air bag, the length ratio of the grinding block to the electromagnet is 3:2, thereby achieving the grinding of the surface of the casting by the up-and-down movement of the grinding block during transportation, the length ratio of the grinding block to the electromagnet is less than 3:2, the surface of the larger casting cannot be completely ground during transportation, thereby failing to achieve effective grinding and reducing product quality, the length ratio of the grinding block to the electromagnet is greater than 3:2, when the two electromagnets attract or repel each other after being powered, the electromagnet lacks attraction or repulsion due to the excessive length of the grinding block, thereby reducing the grinding effect, the grinding block is fixedly installed at 1 / 4-3 / 4 of the electromagnet, thereby achieving central grinding and avoiding deviation to improve the stability of grinding.

[0015] The preferred ejection assembly includes a No. 1 connecting plate, a No. 2 connecting plate, a baffle, a No. 1 connecting rod, a No. 2 connecting rod, a slider, an ejection spring and a connecting column. The base is provided with a groove for the slider to slide left and right. One end of the slider is fixedly installed with an ejection spring. One end of the ejection spring is fixedly installed with a baffle for ejecting the workpiece. After the shearing is completed, the casting falls on the top of the base. If it is not cleaned for a long time, it will cause accumulation and affect the subsequent inability to cut the remaining material of the casting. The baffle will push out the fallen casting when the remaining material of the casting is cut once, thereby realizing the timely ejection of the casting after the cutting is completed to avoid the accumulation of the workpiece. The slider is fixedly installed with a spring that changes the working principle of different parts. The No. 1 connecting rod is in a state, and the end of the No. 1 connecting rod away from the slider is fixedly installed with a No. 1 connecting plate for cleaning debris, and the slider is fixedly installed with a No. 2 connecting rod which cooperates with the No. 1 connecting rod to change different working states, and the other end of the No. 2 connecting rod away from the slider is fixedly installed with a No. 2 connecting plate which cooperates with the No. 1 connecting plate for cleaning. By cooperating with the No. 1 connecting plate and the No. 2 connecting plate, it is possible to clean up the garbage generated by grinding and cutting of castings for a long time, avoiding accumulation and reducing the stability of the equipment. The No. 1 connecting plate and the No. 2 connecting plate are respectively fixedly installed with connecting columns which cooperate with the grinding assembly, so that the grinding assembly can push out the assembly to clean the debris dropped on the base during the return stroke.

[0016] The No. 1 connecting plate and the No. 2 connecting plate are respectively installed with the No. 1 connecting rod and the No. 2 connecting rod for changing the position of the slider. The movement angle of the No. 1 connecting rod and the No. 2 connecting rod is 30°-90°. When the movement angle is less than 30°, when the No. 1 connecting rod and the No. 2 connecting rod drive the baffle to push out the casting that has completed shearing, the sliding movement distance is too small, resulting in the baffle pushing the workpiece away from being too short, which in turn causes the sheared workpiece to accumulate and affect subsequent shearing. When the movement angle is greater than 90°, when the No. 1 connecting plate and the No. 2 connecting plate drive the No. 1 connecting rod and the No. 2 connecting rod to move outward, the No. 1 connecting rod and the No. 2 connecting rod have too large a movement range, resulting in the connecting rod being stuck, thereby reducing the stability of the equipment.

[0017] The distance moved by the No. 1 connecting plate is equal to the distance between the electromagnets, and a grinding block is fixedly installed on the electromagnet, and the grinding block is an arc-shaped sponge block. Since the distance moved by the No. 1 connecting plate is equal to the distance moved during airbag compression and grinding, the distance of the airbag during compression and grinding is equal to the distance between the electromagnets, so that the compression distance of the airbag is equal to the compression distance of the grinding block, thereby avoiding the casting being offset and causing bending deformation due to excessive compression force of the airbag on one side. One end of the grinding block is flat and the other end is semicircular. One end of the grinding block is flat, which fits the electromagnet better and avoids falling off when grinding the surface by shaking up and down, resulting in the subsequent casting being unable to grind the surface. The other end is semicircular. When the casting passes through the grinding assembly, the semicircular grinding head can fit tightly to the surface of the casting during the up and down shaking process, thereby avoiding the situation where the surface of the casting is not polished during the up and down shaking process.

[0018] Beneficial effects of the present invention:

[0019] 1. The present invention provides a device for removing excess material from castings. The device intermittently switches the working state and uses a shearing component in conjunction with a grinding component to remove excess material from castings during shearing. At the same time, the grinding component can clamp the castings, thereby improving the product quality of the castings.

[0020] 2. The present invention provides a device for removing excess material from castings. The device uses a grinding component and a pushing component to cooperate with each other through left and right reciprocating movement. After the shearing is completed, the pushing component can be used to clean the excess material remaining on the base, and at the same time, the previous casting can be pushed out, thereby ensuring a good working environment.

[0021] 3. The present invention provides a casting excess material removal device, which polishes the surface of the casting by means of up and down reciprocating motion, through the electromagnet and the airbag, and using the friction force of the electromagnet. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Example 1: Figure 1-2As shown, the present invention provides a casting waste material removal device, including a hydraulic cylinder 1, a base 2, and also includes a shearing component 3, a grinding component 4, and an ejection component 5. The hydraulic cylinder 1 is fixedly installed on the right side of the base 2, and a vertical plate is provided on the right side of the base 2. The hydraulic cylinder 1 is fixedly installed at 1 / 2 of the vertical plate. The ejection rod of the hydraulic cylinder 1 is connected to the shearing component 3. A shearing component 3 for protection is installed on the base 2 near the hydraulic cylinder 1. The shearing component 3 shears the casting waste material by cross-engaging with the left and right. When the operator is working, the casting waste material is removed by cross-engaging the shearing component 3, thereby protecting the operator during the shearing process to avoid injury to the operator due to the ejection of the casting waste material. The hydraulic cylinder 1 is connected to the shearing component 3. Next, a grinding assembly 4 for intermittent clamping is installed above the shearing assembly 3. When the equipment is working, the shearing assembly 3 does not shear the casting. When the casting with excess material passes through the grinding assembly 4, the grinding assembly 4 will swing up and down, thereby removing the oxide film on the surface of the casting. When the casting to be sheared enters the shearing assembly 3, due to the large size of the casting, it shakes during the shearing process. At this time, the grinding assembly 4 can clamp the casting and cool the casting at the same time, thereby cooling the casting during the shearing process, thereby removing the oxide film on the surface of the casting and clamping and cooling the casting during the shearing process.

[0032] A push-out assembly 5 for assisting in cleaning the shearing assembly 3 is installed below the polishing assembly 4. The push-out assembly 5 is installed above the base plate. When the equipment is working, the casting with residual material is sheared. After a long period of work, the sheared castings will accumulate on the base 2, thereby causing the castings that need to be sheared later to be unable to be sheared. The push-out assembly 5 can push out the castings that have been sheared for the previous time after the shearing is completed, thereby avoiding the accumulation of castings that make it impossible to shear. While the push-out assembly 5 is working, the residual material sheared off the base 2 can be cleaned up, thereby realizing the pushing out of the sheared castings on the one hand, and the cleaning of the residual material sheared on the workbench on the other hand.

[0033] When the casting residue is removed, the workpiece is first passed through the grinding assembly 4 by the conveying device. At this time, the grinding assembly 4 is close to the surface of the casting. Due to the up and down shaking of the grinding assembly 4, the surface of the casting is ground. Then the casting is conveyed to the shearing assembly 3. When the shearing assembly 3 shears the casting, the left and right movement of the hydraulic cylinder 1 drives the shearing assembly 3 to remove the residue of the casting. The shearing assembly 3 and the grinding assembly 4 cooperate to clamp and fix the casting during shearing. At the same time, the grinding assembly 4 can continue to cool the surface of the casting during the shearing process, thereby avoiding bending deformation and reducing product quality due to excessive temperature at the shearing point of the casting. After the shearing is completed, the residue of the casting will remain on the base 2. The grinding assembly 4 and the pushing assembly 5 cooperate to clean the waste remaining on both sides of the base 2, thereby providing a good working environment for the next shearing. When the residue of the casting is sheared next time, the grinding assembly 4 and the pushing assembly 5 cooperate to push out the casting that has been sheared in the previous time, thereby avoiding the accumulation of workpieces that makes shearing impossible.

[0034] like Figure 2-3 As shown, the shearing assembly 3 includes a No. 1 blade 31, a No. 2 blade 32, a connecting column 33, a protective cover 34, a connecting spring 35 and an extrusion head 36. A hydraulic cylinder 1 for providing power is fixedly installed on the right side of the base 2, so that a greater shear force can be provided to thicker castings. The output end of the hydraulic cylinder 1 is fixedly connected to a connecting column 33 that changes the working state. The connecting column 33 is U-shaped, and cylindrical protrusions that match the No. 1 blade 31 and the No. 2 blade 32 are respectively provided on both sides of the connecting column 33. A No. 1 blade 31 is fixedly installed on one side of the connecting column 33. The No. 1 blade 31 is trapezoidal, so that the remaining material of the casting can be cut. A sliding groove is provided at the matching position between the No. 1 blade 31 and the connecting column 33. A No. 2 blade 32 is fixedly installed on the other side of the connecting column 33. The No. 2 blade is rectangular, so that the casting can be fixed during the cutting process. The No. 2 blade 32 and A sliding groove is provided at the joint of the connecting column 33, so that when the connecting column 33 moves left and right through the hydraulic cylinder 1, the No. 1 blade 31 and the No. 2 blade 32 can cross-engage and shear the casting. The upper ends of the No. 1 blade 31 and the No. 2 blade 32 are fixedly installed with a protective cover 34 clamped by the auxiliary grinding component 4, so that the sheared casting residue can be prevented from bursting out during the shearing process, thereby improving the safety of the equipment. The protective cover 34 is divided into two parts, the left and right parts of the protective cover 34 are fixedly installed with connecting springs 35, and the end of the connecting spring 35 away from the protective cover 34 is fixedly installed with an extrusion head 36 for clamping. During the shearing process, the extrusion head 36 will be close to both sides of the casting, so that the auxiliary grinding component 4 can fix and clamp the casting during shearing, avoiding excessive pressure on the casting residue during shearing, which may cause the casting to deviate.

[0035] When shearing starts, the hydraulic cylinder 1 drives the connecting column 33 to move left and right, and the No. 1 blade 31 and the No. 2 blade 32 shear the remaining material of the casting. At this time, the grinding component 4 will be driven to fix and clamp the casting to avoid excessive pressure causing the casting to shift and reduce the shearing effect. During the shearing process, the protective cover 34 on the blade can assist the grinding component 4 to clamp the workpiece through the extrusion head 36. At the same time, the protective cover 34 can prevent the waste generated during the shearing process from bursting out and causing harm to the operator. When the shearing is completed, the blade moves to both sides and drives the grinding component 4 to cooperate with the ejection component 5 to clean up the remaining casting material on the base 2, thereby ensuring a good working environment for the next shearing.

[0036] like Figure 3-4 As shown, the grinding assembly 4 includes an electromagnet 41, an air bag 42, a No. 1 movable plate 43, a No. 2 movable plate 44, a sliding block 45, and a connecting rod 46. The base 2 is slidably installed with a No. 1 movable plate 43 for clamping near the No. 1 blade 31, and a sliding groove for the sliding of the No. 1 movable plate 43 is provided on the base 2. A sliding block 45 matching the sliding groove is provided at the lower end of the No. 1 movable plate 43. The base 2 is slidably installed with a No. 2 movable plate 44 for clamping near the No. 2 blade 32, and a sliding groove for the sliding of the No. 2 movable plate 44 is provided on the base 2. A sliding block 45 matching the sliding groove is provided at the lower end of the No. 2 movable plate 44. The No. 1 movable plate 43 and the No. 2 movable plate can move with the movement of the shearing assembly 3 during shearing, thereby realizing that the grinding assembly 4 fixes and clamps the casting during shearing to avoid the casting from being subjected to excessive force and causing deviation and deformation. The No. 1 movable plate 43 and the No. 2 movable plate 44 are both fixedly installed with a connecting rod for cooling. The airbag 42 can cool down the casting, thereby cooling the casting during the shearing process to accelerate the cooling speed of the casting, and avoid overheating and expansion of the casting, which may cause deformation of the casting. The airbag 42 is fixedly installed with an electromagnet 41 with a grinding surface at one end away from the movable plate. The electromagnet 41 always adheres to both sides of the casting, thereby removing the oxide film on the surface of the casting during transportation, avoiding corrosion and rust of the casting surface by the oxide film, which reduces the product quality of the casting. A connecting rod 46 cooperating with the shearing component 3 is fixedly installed on the right side of the No. 1 movable plate 43, and a connecting rod 46 cooperating with the shearing component 3 is fixedly installed on the right side of the No. 2 movable plate 44, thereby driving the clamping component to clamp the casting when the shearing component 3 shears the remaining material of the casting. The lower ends of the No. 1 movable plate 43 and the No. 2 movable plate 44 are provided with sliding blocks 45 for cooperating with the sliding grooves on the base 2.

[0037] When the casting is conveyed through the polishing assembly 4, the electromagnet 41 is always attached to the surface of the casting. Since the electromagnet 41 is installed on the air bag 42, the electromagnet 41 moves up and down, thereby achieving polishing of the oxide layer on the surface of the casting. When shearing is performed, the first blade 31 and the second blade 32 drive the first moving plate 43 and the second moving plate 44, respectively. The first moving plate 43 and the second moving plate 44 move towards the casting. At this time, the electromagnet 41 on the air bag 42 clamps the casting. At the same time, the air bag 42 blows air to the surface of the casting to cool it, thereby avoiding deformation of the casting due to high surface temperature. After shearing is completed, the shearing assembly 3 is reset and drives the first moving plate 43 and the second moving plate 44 to move to both sides. At this time, the first moving plate 43 and the second moving plate 44 drive the push-out assembly 5 to move, thereby cleaning the debris generated by polishing the casting and the excess material cut off, and further achieving cleaning of the debris on the base 2. In the next shearing process, the push-out assembly 5 moves with the first moving plate 43 and the second moving plate 44 to the middle, thereby pushing out the casting completed by the previous shearing to avoid accumulation of the casting, which prevents subsequent shearing.

[0038] The electromagnet 41 is fixedly installed with a grinding block 47 for clamping at one end away from the air bag 42. The length ratio of the grinding block 47 to the electromagnet 41 is 3:2, thereby enabling the grinding block 47 to move up and down during conveying to polish the surface of the casting. If the length ratio of the grinding block 47 to the electromagnet 41 is less than 3:2, the surface of the casting cannot be completely polished during conveying, thereby failing to achieve effective polishing and reducing product quality. If the length ratio of the grinding block 47 to the electromagnet 41 is greater than 3:2, when the two electromagnets 41 attract or repel each other, the electromagnet 41 lacks attraction or repulsion due to the excessive length of the grinding block 47, thereby reducing the polishing effect. The grinding block 47 is fixedly installed at 1 / 4-3 / 4 of the electromagnet 41, thereby achieving center polishing to avoid deviation and improve polishing stability.

[0039] As shown in FIG. 1, the base 2 is provided with a shearing assembly 3, a polishing assembly 4, a push-out assembly 5, and a conveying assembly 6. Figure 5-7As shown, the ejection assembly 5 includes a No. 1 connecting plate 51, a No. 2 connecting plate 52, a baffle 53, a No. 1 connecting rod 54, a No. 2 connecting rod 55, an ejection spring 56, a slider 57 and a connecting column 58. A groove for the slider 57 to slide left and right is provided on the base 2. A ejection spring 56 is fixedly installed at one end of the slider 57. A baffle 53 for ejecting the workpiece is fixedly installed at one end of the ejection spring 56. After the shearing is completed, the casting falls on the top of the base 2. If it is not cleaned for a long time, it will cause accumulation and affect the subsequent removal of the casting residue. The baffle 53 will clean the fallen casting when the casting residue is removed once. The first connecting rod 54 that changes different working states is fixedly installed on the slider 57, and the end of the first connecting rod 54 away from the slider 57 is fixedly installed with a first connecting plate 51 for cleaning debris. The slider 57 is fixedly installed with a second connecting rod 55 that cooperates with the first connecting rod 54 to change different working states, and the other end of the second connecting rod 55 away from the slider 57 is fixedly installed with a second connecting plate 52 that cooperates with the first connecting plate 51 for cleaning. Through the cooperation of the first connecting plate 51 and the second connecting plate 52, it is possible to grind and remove products from the casting for a long time. The generated garbage is cleaned up to avoid accumulation that reduces the stability of the equipment. When shearing starts, the No. 1 moving plate 43 and the No. 2 moving plate 44 drive the No. 1 connecting plate 51 and the No. 2 connecting plate 52 to move toward the middle, thereby realizing the cleaning of the debris generated by the grinding component 4 when grinding the casting to ensure the good condition of the next work. After the shearing is completed, the No. 1 moving plate 43 and the No. 2 moving plate 44 drive the No. 1 connecting plate 51 and the No. 2 connecting plate 52 to move to both sides, thereby realizing the cleaning of the casting residue dropped on the base 2. When the next shearing work starts, the baffle 53 is moved by the No. 1 connecting rod 54 and the No. 2 connecting rod 55 In coordination, the No. 1 connecting plate 51 and the No. 2 connecting plate 52 drive the No. 1 connecting rod 54 and the No. 2 connecting rod 55 to swing left and right. At this time, the No. 1 connecting rod 54 and the No. 2 connecting rod 55 drive the slider 57 on the base 2 to move left and right, and then the slider 57 drives the baffle 53 to push out the sheared castings, ensuring that subsequent castings can fall in an orderly manner, avoiding accumulation that affects the shearing working environment. The No. 1 connecting plate 51 and the No. 2 connecting plate 52 are respectively fixed with connecting columns 58 that cooperate with the grinding assembly 4, so that the grinding assembly 4 can push out the assembly 5 to clean up the debris dropped on the base 2 during the return stroke.

[0040] The first connecting plate 51 and the second connecting plate 52 are respectively provided with a first connecting rod 54 and a second connecting rod 55 for changing the position of the sliding block, and the movement angle of the first connecting rod 54 and the second connecting rod 55 is 30°-90°, when the movement angle is less than 30°, the first connecting rod 54 and the second connecting rod 55 drive the baffle 53 to push out to complete the shearing of the casting, the sliding movement distance is too small, which causes the baffle 53 to push out the workpiece for a short distance, and then causes the sheared workpiece to accumulate and affect the subsequent shearing, when the movement angle is greater than 90°, the first connecting plate 51 and the second connecting plate 52 drive the first connecting rod 54 and the second connecting rod 55 to move outward, and the movement range of the first connecting rod 54 and the second connecting rod is too large, which causes the connecting rod to be stuck, and then reduces the stability of the equipment, the movement angle of the first connecting rod 54 and the second connecting rod 55 is 60°, which can prevent the baffle 53 from pushing the workpiece out for a sufficient distance to avoid accumulation during movement, and can also prevent the first connecting rod 54 and the second connecting rod 55 from being stuck during movement.

[0041] When the work starts, the workers deliver the casting with excess material to the polishing assembly 4, the surface of the casting is polished to remove the oxide film on the surface of the casting through the up-down shaking of the electromagnet 41, then the first blade 31 and the second blade 32 are driven by the hydraulic cylinder 1 to move the connecting column 33, and then drive the first blade 31 and the second blade 32 to engage to shear the casting, at this time, the first moving plate 43 and the second moving plate 44 of the polishing assembly 4 are driven by the first blade 31 and the second blade 32 to move the casting, at this time, the electromagnet 41 installed on the first moving plate 43 and the second moving plate 44 clamps and fixes the casting to avoid the casting from being offset due to excessive force, at the same time, the air bag 42 is extruded, the air outlet pipe of the air bag 42 cools and cools the cutting part of the casting to prevent the casting from being deformed due to high temperature, when the first blade 31 and the second blade 32 shear the casting, the protective cover 34 on the blade clamps and fixes the casting, which can prevent the excess material from falling out during shearing and shearing and polishing to cause harm to the operator, after shearing is completed, the first moving plate 43 and the second moving plate 44 move to both sides, driving the first connecting plate 51 and the second connecting plate 52 to move to both sides, which can continue to clean the excess material of the casting that falls on the base 2 during polishing and shearing, when the next shearing starts, the baffle 53 is driven by the first connecting plate 51 and the second connecting plate 52 to push out the casting completed by the previous shearing, to avoid the accumulation affecting the subsequent cutting of the casting excess material.

[0042] Embodiment 2: The staff can change the grinding component 4 as needed, so that the grinding component 4 always grinds the surface of the casting during the working process, thereby improving the surface quality of the casting. The electromagnet 41 can be changed to different working states to energize the electromagnets 41 fixedly installed on the No. 1 movable plate 43 and the No. 2 movable plate 44 respectively, so that the electromagnet 41 on the No. 1 movable plate 43 has a positive pole and the electromagnet 41 on the No. 2 movable plate 44 has a negative pole, thereby making the two electromagnets 41 have different electrodes, so that the electromagnets 41 attract each other. At the same time, the electromagnet 41 on the No. 1 movable plate 43 changes the current passed, so that the electromagnet 41 on the No. 1 movable plate 43 has a negative pole, thereby making the two electromagnets 41 have the same electrode, so that the electromagnets 41 repel each other, thereby making the casting intermittently move left and right between the two electromagnets 41 to achieve grinding and ensure the surface quality of the casting.

[0043] A grinding block 47 for clamping is fixedly installed at one end of the electromagnet 41 away from the airbag 42. The length ratio of the grinding block 47 to the electromagnet 41 is 3:2, so that after power is turned on, the grinding block 47 can move intermittently left and right to grind the surface of the casting. The length of the grinding block 47 to the electromagnet 41 is less than 3:2. For larger castings, the surface cannot be completely polished during transportation, and effective polishing cannot be achieved, which reduces product quality. The length ratio of the grinding block 47 to the electromagnet 41 is greater than 3:2. After the electromagnet 41 is powered on, when the two electromagnets 41 attract or repel each other, the grinding block 47 is too long, resulting in insufficient attraction or repulsion of the electromagnet 41, which reduces the grinding effect. The grinding block 47 is fixedly installed at 1 / 4-3 / 4 of the electromagnet 41, so that center grinding can be achieved to avoid offset and improve grinding stability.

[0044] The electromagnet 41 is always in contact with both sides of the casting. After the electromagnet 41 is energized, the oxide film on the surface of the casting can be removed during the shearing process to prevent the surface of the casting from being corroded and rusted by the oxide film, which reduces the product quality of the casting. A connecting rod 46 that cooperates with the shearing component 3 is fixedly installed on the right side of the No. 1 movable plate 43. A connecting rod that cooperates with the shearing component 3 is fixedly installed on the right side of the No. 2 movable plate 44. It can drive the grinding component 4 to cool the casting when the shearing component 3 shears the remaining material of the casting. The lower ends of the No. 1 movable plate 43 and the No. 2 movable plate 44 are both provided with useful With the sliding block 45 cooperating with the sliding groove on the base 2, after the shearing is completed, the shearing assembly 3 is reset and drives the No. 1 movable plate 43 and the No. 2 movable plate 44 to move to both sides. At this time, the No. 1 movable plate 43 and the No. 2 movable plate 44 drive the ejection assembly 5 to move, and clean up the debris generated by the grinding of the casting and the remaining material removed, thereby realizing the cleaning of the debris on the base 2. In the next shearing process, the ejection assembly 5 moves toward the middle with the No. 1 movable plate 43 and the No. 2 movable plate 44, thereby realizing the ejection of the casting completed in the previous shearing to avoid the accumulation of castings and the inability to perform subsequent shearing.

[0045] At the beginning of the work, the staff transports the casting with the residual material to the grinding assembly 4, and passes the current to the electromagnet 41 so that the electromagnet 41 carries the current of different electrodes, thereby making the electromagnet 41 realize intermittent repulsion and attraction, thereby making the electromagnet 41 grind the surface of the casting to remove the oxide film on the surface of the casting, and then the No. 1 blade 31 and the No. 2 blade 32 are driven by the hydraulic cylinder 1, so that the connecting column 33 moves, thereby driving the No. 1 blade 31 and the No. 2 blade 32 to engage and shear the casting. At this time, the No. 1 moving plate 43 and the No. 2 moving plate 44 of the grinding assembly 4 are driven by the No. 1 blade 31 and the No. 2 blade 32 to move the casting. At this time, the airbags 42 installed on the No. 1 moving plate 43 and the No. 2 moving plate 44 are on the casting. The parts are cooled down to prevent the castings from being deformed due to excessive temperature. When the No. 1 blade 31 and the No. 2 blade 32 shear the castings, the protective cover 34 on the blades clamps and fixes the castings, thereby preventing the sheared and polished residue from bursting out during the shearing process and causing harm to the operator. After the shearing is completed, when the No. 1 movable plate 43 and the No. 2 movable plate 44 move to both sides, they drive the No. 1 connecting plate 51 and the No. 2 connecting plate 52 to move to both sides, thereby continuing to clean up the residue that has fallen on the base 2 due to polishing and shearing. At the beginning of the next shearing, the baffle 53 is driven by the No. 1 connecting plate 51 and the No. 2 connecting plate 52 to push out the castings that have been sheared in the previous time, so as to avoid accumulation that affects the subsequent removal of residue from castings.
