Description

Technical Field

[0001] This invention relates to the field of metal processing technology, specifically to a metal cutting device with anti-splash function. Background Technology

[0002] In the field of metal processing, during the cutting process, metal workpieces are subjected to shearing or impact forces, which can easily cause spattering.

[0003] Existing anti-splash devices mostly adopt rigid fixed structures, and their height and angle cannot be dynamically adjusted according to the workpiece size and cutting thickness. When cutting thick steel plates, the kinetic energy of the splashes is large, which may penetrate the baffle or cause secondary splashing due to rebound. This not only threatens the safety of operators, but may also damage surrounding equipment. After cutting, the unloading process relies on manual handling. For heavy workpieces, it is easy to cause operator fatigue, and there is a risk of scratches when the hands come into contact with the cutting area. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a metal cutting device with anti-splash function, which solves the problems that traditional rigid protective devices cannot adapt to workpieces of different thicknesses and cannot achieve full-enclosure protection.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a metal cutting device with anti-splash function, comprising a shearing bed and a cutting device. The top of the shearing bed is fixedly connected to the cutting device. An anti-splash device is fixedly connected to the outer wall of the cutting device. A grinding device is slidably connected to the outer wall of the cutting device. The outer wall of the grinding device is fixedly connected to the inner wall of the shearing bed. An auxiliary device is slidably connected to the inner wall of the shearing bed. The cutting end of the cutting device contacts the top of the auxiliary device. The anti-splash device guides the material that bounces off the cutting device after cutting through a flexible component for discharge. The grinding device... The device cleans the cutting end of the cutting device by moving the cutting device. The anti-splash device includes a bellows, which is square in shape. Cylinders are symmetrically fixed to the outer wall of the bellows, and four fixing rods are fixed to the inner wall of the bellows. A limit shaft is fixed to the end of the fixing rod away from the bellows. The limit shaft is frame-shaped. The anti-splash device adopts a combination structure of square bellows and flexible guide plate. The bellows is driven to rise and fall by cylinders. The opening angle of the flexible guide plate is controlled by the limit shaft and the spring. It can form a full-enclosed guide for the processed object that bounces after cutting.

[0008] Preferably, the top end of the bellows is fixedly connected to the outer wall of the cutting device, and the outer wall of the cylinder is fixedly connected to the outer wall of the cutting device.

The flexible guide plate uses its own deformation to conform to the splash trajectory of workpieces of different sizes, avoiding the blind spots of traditional rigid protection. This effectively prevents equipment damage or personnel safety hazards caused by metal chips or workpieces splashing. The automatic reset function of the spring ensures that the guide plate is quickly stored after the cutting operation is completed, without affecting the next operation of the equipment, and at the same time avoids the increase in workshop cleaning costs caused by material scattering.

A material discharge groove is formed on the inner wall of the fixed block, and the inner wall of the material discharge groove is arranged in a linear array along the inner wall of the fixed block. By utilizing the up-and-down movement of the cutting blade in the cutting device, the grinding stone and the surface dotted pattern automatically rub and clean the outer wall of the cutting blade.

[0017] (III) Beneficial Effects

[0018] This invention provides a metal cutting device with anti-splash function. It has the following beneficial effects:

[0019] (I) The metal cutting equipment with anti-splash function adopts a combination structure of corrugated pipe and flexible guide plate through the anti-splash device. The corrugated pipe is driven to rise and fall by a cylinder, and the flexible guide plate is controlled to unfold at an angle by a limit shaft and a spring. It can form a full-enclosed guide for the workpiece that flies after cutting.

[0020] (ii) The metal cutting equipment with anti-splash function, through the anti-splash device, the corrugated structure of the corrugated pipe can extend and retract synchronously with the lifting and lowering of the cutting device. Combined with the sliding characteristics of the flexible guide plate, it can adapt to the cutting of metal plates of different thicknesses. The automatic reset function of the spring ensures that the guide plate can be quickly stored after the cutting operation is completed, without affecting the next operation of the equipment, and at the same time avoids the increase in workshop cleaning costs caused by material spillage.

[0021] (III) The metal cutting equipment with anti-splash function supports the grinding stone through the fixed block and fixed plate in the grinding device. By using the up and down movement of the cutting blade in the cutting device, the grinding stone and surface dots automatically rub and clean the outer wall of the cutting blade. The linear array design of the dots can specifically remove the metal debris or oxide layer remaining on the blade and avoid debris adhesion.

[0022] (iv) The metal cutting equipment with anti-splash function provides a stable placement and limiting structure for the workpiece through the auxiliary device, the sliding plate, auxiliary groove and cutting groove in the auxiliary device, and the flip plate realizes automatic reset through the limiting rod. After the cutting is completed, it can help the workpiece slide down to the discharge groove, which is linked with the flow guiding function of the anti-splash device. The operator does not need to manually clean the workpiece or debris, reducing the frequency of contact with the equipment. Attached Figure Description

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

[0034] Please see Figure 1-8 This invention provides a technical solution: a metal cutting device with anti-splash function.

[0035] A shearing machine 1 and a cutting device 2 are included. The top of the shearing machine 1 is fixedly connected to the cutting device 2. An anti-splash device 3 is fixedly connected to the outer wall of the cutting device 2. A grinding device 4 is slidably connected to the outer wall of the cutting device 2. The outer wall of the grinding device 4 is fixedly connected to the inner wall of the shearing machine 1. An auxiliary device 5 is slidably connected to the inner wall of the shearing machine 1. The cutting end of the cutting device 2 is in contact with the top of the auxiliary device 5. The anti-splash device 3 guides the material that is cut and blown away by the cutting device 2 through a flexible component. The grinding device 4 cleans the cutting end of the cutting device 2 by using the movement of the cutting device 2. A flat metal strip is placed above the shearing machine 1, and then the cutting device 2 is started to cut. During this process, the anti-splash device 3 moves down synchronously. After the cutting is completed, the auxiliary device 5 and the grinding device 4 cooperate to grind and clean the cutting blade 22.

[0036] The anti-splash device 3 includes a bellows 30, which is square in shape. A cylinder 31 is symmetrically fixed to the outer wall of the bellows 30, and a fixing rod 32 is fixed to the inner wall of the bellows 30. There are four fixing rods 32. A limiting shaft 33 is fixedly connected to the end of the fixing rod 32 away from the bellows 30. The limiting shaft 33 is frame-shaped. The top of the bellows 30 is fixedly connected to the outer wall of the cutting device 2, and the outer wall of the cylinder 31 is fixedly connected to the outer wall of the cutting device 2. When the cutting operation is started, the cylinder 31 drives the square bellows 30 to descend along the outer wall of the cutting device 2. The bellows 30 drives the frame-shaped limiting shaft 33 at the top to move down synchronously through the fixing rod 32. At this time, the spring 34 fixed in the groove of the inner wall of the limiting shaft 33 releases elastic potential energy, causing the flexible guide plate 35 to unfold. The outer wall of the flexible guide plate 35 and the cutting area form an enclosing structure.

[0037] A spring-loaded spring 34 is fixedly connected to the inner wall of the limiting shaft 33 via a slot. A flexible guide plate 35 is fixedly connected to the end of the spring-loaded spring 34 away from the limiting shaft 33. A limiting strip 36 is slidably connected to the end of the flexible guide plate 35 away from the spring-loaded spring 34. A discharge pipe 37 is provided below the flexible guide plate 35, and a discharge groove 38 is provided below the corrugated pipe 30. The slot is formed in the wall of the limiting shaft 33. The outer wall of the flexible guide plate 35 is in contact with the workpiece. The outer wall of the flexible guide plate 35 is slidably connected to the inner wall of the corrugated pipe 30. The outer wall of the limiting strip 36 is in contact with the outer wall of the corrugated pipe 30. The discharge pipe 37... The top end of the flexible guide plate 35 is fixedly connected to the bottom end of the shearing machine 1. The discharge trough 38 is opened on the inner wall of the shearing machine 1. After the cutting spatter or the workpiece comes into contact with the flexible guide plate 35, it is guided by its inclined surface to slide downward and finally fall into the discharge pipe 37 and collect in the discharge trough 38 on the inner wall of the shearing machine 1. The end of the flexible guide plate 35 away from the spring 34 slides along the limiting strip 36. The limiting strip 36 only serves to limit the guide plate from sliding out and does not participate in the angle adjustment. After the cutting is completed, the cylinder 31 drives the bellows 30 to rise. The flexible guide plate 35 is squeezed by the inner wall of the bellows 30 and is retracted and reset by the spring 34.

[0038] The polishing device 4 includes a fixed block 40, with a fixed plate 41 symmetrically fixedly connected to the top of the fixed block 40. A compression spring 42 is fixedly connected to the outer wall of the fixed plate 41. A passive plate 43 is fixedly connected to the end of the compression spring 42 away from the fixed plate 41. A polishing stone 44 is fixedly connected to the end of the passive plate 43 away from the compression spring 42. A dotted pattern 45 is fixedly connected to the end of the polishing stone 44 away from the passive plate 43. The outer wall of the dotted pattern 45 is arranged in a linear array along the outer wall of the polishing stone 44. A sliding rod 46 is fixedly connected to the bottom of the passive plate 43. The inner wall of the 0 is provided with a material drop groove 47. The inner wall of the material drop groove 47 is arranged in a linear array along the inner wall of the fixed block 40. The outer wall of the fixed block 40 is fixedly connected to the inner wall of the shearing machine 1. The outer walls of the polishing stone 44 and the polka dot 45 are slidably connected to the cutting end of the cutting device 2. The outer wall of the slide rod 46 is slidably connected to the inner wall of the fixed block 40 through a slide groove, and the slide groove is opened in the wall of the fixed block 40. When the hydraulic cylinder 21 of the cutting device 2 drives the cutting blade 22 to move downward, the outer wall of the cutting blade 22 contacts the polishing stone 44 and the polka dot 45 on the surface in the polishing device 4. As the cutting blade 22 continues to move downwards, the passive plate 43, under the elastic support of the fixed plate 41 and the compression spring 42, drives the polishing stone 44 to adhere tightly to the surface of the cutting blade 22. The dotted surface 45, through the linearly distributed raised structure, specifically scrapes away the metal debris or oxide layer remaining on the blade. At the same time, the sliding rod 46 at the bottom of the passive plate 43 slides along the groove on the inner wall of the fixed block 40 to ensure uniform polishing pressure. The debris generated during polishing is discharged through the linearly distributed discharge groove 47 on the inner wall of the fixed block 40 to avoid accumulation and affect the cleaning effect. After cutting, when the cutting blade 22 returns to its original position, it contacts the polishing stone 44 again to achieve secondary cleaning and ensure that the cutting end is always in a clean state.

[0039] The auxiliary device 5 includes a slide plate 50, an auxiliary groove 51 and a cutting groove 52 on the upper part of the slide plate 50, and the outer wall of the slide plate 50 is slidably connected to the inner wall of the shearing machine 1. The auxiliary groove 51 and the cutting groove 52 are formed on the inner wall of the shearing machine 1. The auxiliary device 5 also includes a limiting rod 53, and a flip plate 54 is rotatably connected to the outer wall of the limiting rod 53. The two ends of the limiting rod 53 are fixedly connected to the inner wall of the shearing machine 1, and the outer wall of the flip plate 54 is slidably connected to the inner wall of the shearing machine 1. During cutting, the workpiece is placed above the slide plate 50, and then the cutting blade 22 moves down to cut the workpiece. After cutting, the workpiece bounces and falls to the top of the flip plate 54 under the action of gravity, pushing the flip plate 54 to rotate along the limit rod 53. After the flip plate 54 tilts, it guides the workpiece to the discharge chute 38, which is linked with the flow guide of the anti-splash device 3. The flip plate 54 returns to its original position by its own gravity and adheres to the inner wall of the shearing machine 1 without affecting the next operation. After cutting, the slide plate 50 is pulled out from the inner wall of the shearing machine 1. During this process, the workpiece above the slide plate 50 falls from the auxiliary groove 51, and the cutting device 2 moves down from the cutting groove 52 and slides against the outer wall of the grinding device 4 for grinding and cleaning.

[0040] The cutting device 2 includes a U-shaped frame 20, with a hydraulic cylinder 21 fixedly connected to the top of the U-shaped frame 20. The output end of the hydraulic cylinder 21 is fixedly connected to a cutting blade 22 via a round shaft. The inner wall of the U-shaped frame 20 is fixedly connected to the outer wall of the cylinder 31, and the outer wall of the U-shaped frame 20 is fixedly connected to the top of the corrugated pipe 30. The outer wall of the cutting blade 22 is slidably connected to the inner wall of the cutting groove 52, and the outer wall of the cutting blade 22 is slidably connected to the outer walls of the polishing stone 44 and the dot 45. The U-shaped frame 20 of the cutting device 2 provides fixed support for the cylinder 31 and the corrugated pipe 30 of the anti-splash device 3, ensuring that the anti-splash range corresponds precisely to the cutting area. The lifting and lowering action of the cutting blade 22 synchronously drives the polishing device 4 to complete the cleaning, without the need for an additional power source.

[0041] When in use, place the flat metal strip above the shearing machine 1, and then start the cutting device 2 to cut. During this process, the anti-splash device 3 moves down synchronously. After the cutting is completed, the auxiliary device 5 and the grinding device 4 work together to grind and clean the cutting blade 22.

[0042] When the cutting operation is started, the cylinder 31 drives the square bellows 30 to descend along the outer wall of the cutting device 2. The bellows 30 drives the frame-shaped limiting shaft 33 at the top to move down synchronously through the fixed rod 32. At this time, the spring 34 fixed in the groove on the inner wall of the limiting shaft 33 releases elastic potential energy, causing the flexible guide plate 35 to unfold. The outer wall of the flexible guide plate 35 and the cutting area form an enclosing structure.

[0043] After the cutting spatter or the workpiece comes into contact with the flexible guide plate 35, it is guided downward by its inclined surface and eventually falls into the discharge pipe 37 and collects in the discharge groove 38 on the inner wall of the shearing machine 1. The end of the flexible guide plate 35 away from the spring 34 slides along the limiting strip 36. The limiting strip 36 only serves to limit the guide plate from sliding out and does not participate in angle adjustment. After the cutting is completed, the cylinder 31 drives the bellows 30 to rise. The flexible guide plate 35 is squeezed by the inner wall of the bellows 30 and is retracted and reset by the spring 34.

[0044] When the hydraulic cylinder 21 of the cutting device 2 drives the cutting blade 22 to move downward, the outer wall of the cutting blade 22 contacts the grinding stone 44 and the surface dots 45 in the grinding device 4. As the cutting blade 22 continues to move downward, the passive plate 43, under the elastic support of the fixed plate 41 and the compression spring 42, drives the grinding stone 44 to adhere tightly to the surface of the cutting blade 22. The dots 45, through the linearly distributed raised structure, selectively scrape away the metal debris or oxide layer remaining on the blade. At the same time, the sliding rod 46 at the bottom of the passive plate 43 slides along the groove on the inner wall of the fixed block 40 to ensure uniform grinding pressure. The debris generated during grinding is discharged through the linearly distributed discharge groove 47 on the inner wall of the fixed block 40 to avoid accumulation and affect the cleaning effect. After cutting, when the cutting blade 22 returns to its original position, it contacts the grinding stone 44 again to achieve secondary cleaning and ensure that the cutting end is always in a clean state.

[0045] During cutting, the workpiece is placed above the slide plate 50, and then the cutting blade 22 moves down to cut the workpiece. After cutting, the workpiece bounces and falls to the top of the flip plate 54 under the action of gravity, pushing the flip plate 54 to rotate along the limit rod 53. After the flip plate 54 tilts, it guides the workpiece to the discharge chute 38, which is linked with the flow guide of the anti-splash device 3. The flip plate 54 returns to its original position by its own gravity and adheres to the inner wall of the shearing machine 1 without affecting the next operation. After cutting, the slide plate 50 is pulled out from the inner wall of the shearing machine 1. During this process, the workpiece above the slide plate 50 falls from the auxiliary groove 51, and the cutting device 2 moves down from the cutting groove 52 and slides against the outer wall of the grinding device 4 to perform grinding and cleaning.

[0046] The U-shaped frame 20 of the cutting device 2 provides fixed support for the cylinder 31 and bellows 30 of the anti-splash device 3, ensuring that the anti-splash range corresponds precisely to the cutting area. The lifting action of the cutting blade 22 synchronously drives the grinding device 4 to complete the cleaning, without the need for an additional power source.
