Abstract
Description
Technical Field
[0001] This invention belongs to the field of metal combination processing, specifically a machine for bending and cutting metal. Background Technology
[0002] When flat metals are bent and cut, they are usually first transported to the bending mechanism through positioning. Then, the reciprocating movement of the metal is used to achieve various bending shapes. Finally, the bent metal end is transported to the cutting structure and cut by the cutting mechanism to complete the bending and cutting of the metal.
[0003] A patent document with publication number CN120663141B discloses a bending and cutting device for processing stainless steel round bars, including a conveying processing component, an upper abutment component, a bending component, a conveying limit block and a base plate. An adjustable auxiliary component is installed on one side of the conveying limit block. The adjustable auxiliary component includes a fixed plate fixedly installed above the base plate and a movable plate movably installed above the base plate.
[0004] When bending and cutting thick, flat metal, the metal is usually first fed into the bending mechanism by an automatic feeding mechanism to be bent before cutting. However, during the cutting process, the metal end outside the cutting mechanism lacks effective support, and its suspended state causes violent vibration and displacement at the moment of cutting, resulting in quality defects such as tilted cuts and burr buildup. Furthermore, the two cut surfaces formed after cutting thick metal plates need to be transferred to a centralized grinding station for post-processing. During this process, the exposed sharp burrs can easily scratch the conveyor belt and surrounding equipment, and the generated metal debris can scatter everywhere, polluting the working environment. Moreover, after the cut surfaces are left for a long time, the oxide layer and burrs become tightly bonded, greatly increasing the difficulty and processing cost of subsequent grinding, and seriously affecting the surface quality of the product and the continuity of production.
[0005] Therefore, the present invention provides a machine for bending and cutting metal to solve the problems in the background art described above. Summary of the Invention

A positioning conveyor is fixedly installed on the side of the bending device. A metal conveying mechanism and a positioning fixture are also installed above the machine base. A flat metal component is conveyed and placed inside the metal conveying mechanism and the positioning fixture. A clamping and grinding mechanism is also movably installed above the machine base. The clamping and grinding mechanism is located between the positioning conveyor and the lifting cutting component. The metal conveying mechanism and positioning conveyor are used to convey the flat metal parts to the bending equipment for bending. The lifting cutting component is used to cut the bent flat metal parts. The clamping and grinding mechanism includes a fixed plate fixedly installed above the machine table and a telescopic component fixedly installed on the side of the fixed plate. A clamping and grinding component is fixedly installed at one end of the telescopic component. The clamping and grinding component has an internal feeding chamber and two conveying chambers. The feeding chamber is open on the side facing the flat metal component. The mechanism block has an internal grinding chamber. The grinding chamber, conveying chamber and feeding chamber are connected. The grinding chamber has a movable structure for grinding the two cut surfaces of the flat metal component.
[0007] Preferably, the bending equipment includes a movable component fixedly installed above the machine base, a housing is installed above the movable component, and bending fixtures are installed on the side of the housing facing the flat metal part.
[0008] Preferably, the bending fixture includes a fixed platform fixedly installed on one side of the machine housing and a rotary platform rotatably installed on the outside of the fixed platform, with two bending abutments installed on one side of the rotary platform.
[0009] Preferably, the two bending abutments are installed at the upper and lower positions of the rotating table, and two positioning irregular blocks are fixedly installed on one side of the fixed table. The distance between the two positioning irregular blocks is used to position the flat metal parts.
[0010] Preferably, multiple conveying rollers are movably installed inside the conveying cavity, and the spacing of the conveying rollers is used to convey flat metal parts. The two conveying cavities are opened on opposite sides of the mechanism block.
[0011] Preferably, the mechanism block has two lifting chambers inside, and the lifting chambers are connected to the grinding chamber, the feeding chamber and a corresponding set of conveying chambers.
[0012] Preferably, a receiving abutment is fixedly installed at the bottom of the lifting cavity, and a lifting clamp is installed at the top of the lifting cavity in a lifting manner. The horizontal height of the receiving abutment is lower than the horizontal height of the flat metal part inside the mechanism block. When the lifting clamp descends and contacts the receiving abutment, it is used to clamp the flat metal part inside the lifting cavity.
[0013] Preferably, a movable mechanism is installed at the top of the grinding chamber, a linkage box is fixedly installed below the movable mechanism, a grinding component is movably installed at the bottom of the linkage box, a movable motor is fixedly installed above the linkage box, and the movable motor is fixedly connected to the movable mechanism.
[0014] Preferably, the grinding assembly includes a connecting column rotatably installed inside the linkage box and grinding wheels fixedly installed on both sides of the connecting column. A transmission ring and a transmission shaft are also rotatably installed at the bottom of the linkage box. The transmission shaft and the transmission ring mesh with each other.

[0016] The beneficial effects of this invention are as follows: 1. The present invention discloses a machine for bending and cutting metal. A flat metal part is bent inside a bending device at its end. Then, the positioning conveyor and bending device disengage from the bent end of the flat metal part. The metal conveying mechanism reverses the flow, bringing the bent end of the flat metal part closer to the positioning fixture. At this point, the extension of the telescopic component allows the flat metal part to be inserted into the conveying cavity through the feeding chamber for positioning. Both ends of the flat metal part near the cutting position are clamped and positioned. A lifting cutting component then cuts the part. Both cut surfaces are then placed inside a grinding chamber, where a structure for grinding the two cut surfaces of the flat metal part is used. This completes the combined bending, cutting, and grinding process.
[0017] 2. The machine for bending and cutting metal according to the present invention has two cutting surfaces located inside the grinding chamber. Under the lifting action of the lifting clamp, the lifting clamp descends and abuts against the upper part of the bending part or initial part corresponding to its position. At this time, the receiving strip below the lifting clamp supports the lower part of the corresponding bending part or initial part. That is, the setting of the two lifting clamps and the receiving strip can further position the two cutting surfaces, thereby facilitating subsequent grinding and avoiding the problem of displacement and shaking of the cutting surface of the flat metal part at the beginning of subsequent grinding work.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0022] Example 1: As Figures 1-3 and Figures 5-6 As shown, an embodiment of the present invention provides a machine for bending and cutting metal, including a machine base 1, a lifting cutting component 5 and a bending device 2 mounted on the machine base 1, a positioning conveyor 4 fixedly mounted on the side of the bending device 2, a metal conveying mechanism 11 and a positioning fixture 13 mounted above the machine base 1, a flat metal component 12 being conveyed and placed inside the metal conveying mechanism 11 and the positioning fixture 13, and a clamping and grinding mechanism 3 movably mounted above the machine base 1, the clamping and grinding mechanism 3 being positioned between the positioning conveyor 4 and the lifting cutting component 5. The metal conveying mechanism 11 and the positioning conveying component 4 are used to convey the flat metal part 12 to the bending equipment 2 for bending. The lifting cutting component 5 is used to cut the bent flat metal part 12. The clamping and grinding mechanism 3 includes a fixed plate 31 fixedly installed above the machine base 1 and a telescopic component 32 fixedly installed on the side of the fixed plate 31. A clamping and grinding component 33 is fixedly installed at one end of the telescopic component 32. The interior of the clamping and grinding part 33 is provided with a feeding chamber 333 and two conveying chambers 332. The feeding chamber 333 is open on the side facing the flat metal part 12. The interior of the mechanism block 331 is provided with a grinding chamber 335. The grinding chamber 335, the conveying chamber 332 and the feeding chamber 333 are connected. The interior of the grinding chamber 335 is movably equipped with a structure for grinding the two cut surfaces of the flat metal part 12.
[0023] Specifically, the flat metal part 12 to be bent and cut is inserted into the metal conveying mechanism 11. After being conveyed forward by the metal conveying mechanism 11, the end of the flat metal part 12 extends from the groove of the positioning fixture 13 into the interior of the positioning conveyor 4. As the flat metal part 12 continues to be conveyed, the end of the flat metal part 12 will be bent inside the bending device 2. At this time, the positioning conveyor 4 and the bending device 2 can be moved, thereby allowing the positioning conveyor 4 and the bending device 2 to disengage from the end of the bent flat metal part 12. Through the reverse conveying of the metal conveying mechanism 11, the end of the bent flat metal part 12 is brought closer to the positioning fixture. Install 13 until the cutting point is below the lifting cutting member 5. At this time, through the extension of the telescopic member 32, the clamping grinding member 33 moves towards the flat metal part 12, so that the flat metal part 12 is inserted into the inside of the conveying chamber 332 through the feeding chamber 333 for positioning. That is, at this time, both ends of the flat metal part 12 near the cutting position are clamped and positioned. Then, the lifting cutting member 5 cuts it. The cutting in this form will not cause the metal end to lack effective support, and the suspended state will not cause violent vibration and displacement at the moment of cutting, resulting in quality defects such as tilted cut and burr growth. After the flat metal part 12 is cut, it forms a bent fold. The bent part and the initial part that has not yet been bent are both in the same process. At this time, the end of the bent part is inside the mechanism block 331, while the initial part is inside the metal conveying mechanism 11 and the positioning fixture 13. The initial part is conveyed by the metal conveying mechanism 11 so that the end of the initial part enters the nearest conveying cavity 332. At the same time, the two conveying cavities 332 of the end of the bent part convey it so that the end of the bent part enters the other set of conveying cavities 332. That is, at this time, both cut surfaces are inside the grinding cavity 335. Then, the two cut surfaces of the flat metal part 12 are ground by the structure inside the grinding cavity 335, thereby completing the bending and cutting and the cut surfaces. The combined grinding and polishing process avoids the problem of sharp burrs exposed during concentrated grinding after bending and cutting the flat metal part 12 scraping the conveyor belt and surrounding equipment during the conveying process, and the resulting metal debris scattering everywhere and polluting the working environment. It also avoids the problem of oxide layer and burrs tightly bonding to the cut surface of the flat metal part 12 after being left for a long time, which greatly increases the difficulty and processing cost of subsequent grinding, seriously affecting the surface quality of the product and the continuity of production. After the grinding work is completed, the telescopic part 32 retracts, so that the clamping grinding part 33 moves away from the flat metal part 12 and is taken away by the cut-off bent part, while the remaining initial part continues to undergo the next bending and cutting work.
[0024] like Figures 3-4 As shown, the bending equipment 2 includes a movable component 21 fixedly installed above the machine base 1, a housing 22 installed above the movable component 21, and a bending fixture 23 installed on the side of the housing 22 facing the flat metal part 12.
[0025] The bending fixture 23 includes a fixed platform 232 fixedly installed on one side of the housing 22 and a rotating platform 231 rotatably installed on the outside of the fixed platform 232. Two bending abutments 233 are installed on one side of the rotating platform 231.
[0026] Two bent abutments 233 are installed at the upper and lower positions of the rotating table 231. Two positioning irregular blocks 234 are fixedly installed on one side of the fixed table 232. The distance between the two positioning irregular blocks 234 is used to position the flat metal part 12.
[0027] Specifically, when the end of the flat metal part 12 is conveyed and extended to the side of the positioning fixture 13 via the metal conveying mechanism 11, the bending fixture 23 and the positioning conveyor 4 move synchronously toward the flat metal part 12 under the action of the moving component 21, until the end of the flat metal part 12 is inside the positioning conveyor 4 and the bending fixture 23. The positioning conveyor 4 can perform the work of supporting, positioning and synchronous conveying. When the end of the flat metal part 12 is inside the bending fixture 23, it will be within the distance between the two positioning irregular blocks 234, and the flat metal part 12 will be repositioned. Then, the two bending abutments 233 will be rotated by the rotary table 231. When the bending abutment 233 is above the rotary table 231, it will rotate downwards. When the flat metal part 12 is in motion, it will press against the outer side of the end of the flat metal part 12, causing the end of the flat metal part 12 to bend downward. Similarly, when the other set of bending abutments 233 rotates upward, it will press against the outer side of the end of the flat metal part 12, causing the end of the flat metal part 12 to bend upward. During this bending process, it needs to be coordinated with the positioning conveyor 4 and the metal conveying mechanism 11 to make different turning points of the end of the flat metal part 12 contact the two bending abutments 233. After the flat metal part 12 is bent, the moving component 21 moves and drives the bending fixture 23 and the positioning conveyor 4 away from the flat metal part 12. At this time, under the reverse conveying of the metal conveying mechanism 11, the bent part of the flat metal part 12 can be brought close to the lifting cutting component 5, thereby completing the subsequent cutting work.
[0028] like Figures 6-8 As shown, multiple conveying rollers 334 are movably installed inside the conveying cavity 332. The spacing of the conveying rollers 334 is used to convey the flat metal part 12. Two conveying cavities 332 are opened on the opposite sides of the mechanism block 331.
[0029] The mechanism block 331 has two lifting chambers 336 inside, which are connected to the grinding chamber 335, the feeding chamber 333 and a corresponding set of conveying chambers 332.
[0030] A receiving abutment bar 3362 is fixedly installed at the bottom of the lifting cavity 336, and a lifting clamping plate 3361 is lifted and installed at the top of the lifting cavity 336. The horizontal height of the receiving abutment bar 3362 is lower than the horizontal height of the flat metal part 12 inside the mechanism block 331. When the lifting clamping plate 3361 descends and contacts the receiving abutment bar 3362, it is used to clamp the flat metal part 12 inside the lifting cavity 336.
[0031] A movable mechanism 337 is installed on the top of the grinding chamber 335. A linkage box 339 is fixedly installed below the movable mechanism 337. A grinding component 338 is movably installed at the bottom of the linkage box 339. A movable motor 3391 is fixedly installed above the linkage box 339. The movable motor 3391 is fixedly connected to the movable mechanism 337.
[0032] The grinding assembly 338 includes a connecting column 3382 rotatably installed inside the linkage box 339 and grinding wheels 3381 fixedly installed on both sides of the connecting column 3382. A transmission ring 3392 and a transmission shaft 3393 are also rotatably installed at the bottom of the linkage box 339. The transmission shaft 3393 and the transmission ring 3392 mesh with each other. The output shaft of the mobile motor 3391 is connected to the transmission shaft 3393 with the shaft facing downward. The transmission ring 3392 is sleeved on the outside of the center position of the connecting column 3382.
[0033] Specifically, after the flat metal part 12 is cut, it continues to be conveyed by the metal conveying mechanism 11 and multiple conveying rollers 334, so that both cut surfaces of the flat metal part 12 enter the mechanism block 331. At this time, one end of the bent part formed after the flat metal part 12 is in a set of conveying cavities 332, while the other cut initial part end is in another set of conveying cavities 332. That is, both cut surfaces are in the grinding cavity 335. Under the lifting action of the lifting clamp 3361, the lifting clamp 3361 descends and abuts against the upper part of the bent part or initial part corresponding to its position. At this time, the receiving strip 3362 below the lifting clamp 3361 supports the lower part of the corresponding bent part or initial part. That is, the arrangement of the two lifting clamps 3361 and the receiving strip 3362 can... The positions of the two cut surfaces are further positioned to facilitate subsequent grinding and avoid displacement and vibration of the cut surfaces of the flat metal part 12 at the beginning of the subsequent grinding work. After the two cut surfaces of the flat metal part 12 are further clamped and positioned, the moving mechanism 337 drives the moving motor 3391, the linkage box 339 and the grinding assembly 338 to move toward the two cut surfaces through electric drive. At the same time, the moving motor 3391 drives its output shaft, transmission shaft 3393 and transmission ring 3392 to rotate, thereby driving the connecting column 3382 and the two grinding wheels 3381 to rotate at high speed. At this time, the two moving and high-speed rotating grinding wheels 3381 grind the two cut surfaces respectively, completing the combined processing of bending and cutting of thick metal flat plates and grinding of the cut surfaces.
[0034] Example 2: Figure 6 As shown in the first embodiment, another embodiment of the present invention is as follows: a bellows 3311 is fixedly installed on one side of the mechanism block 331, and a plurality of connecting slots 3312 are opened on the side of the bellows 3311 facing the grinding chamber 335. A duct 3313 is fixedly installed on the side of the bellows 3311 facing outward, and the duct 3313 is connected to an external extraction device.
[0035] Specifically, after the two bent parts and the initial part of the flat metal part 12 are cut off, they are pressed down and held by the two lifting clamps 3361 respectively. At this time, a near-sealed space is formed inside the grinding chamber 335. When the grinding wheel 3381 rotates at high speed to carry out the grinding work, the external suction equipment works, so that the suction force is applied to the inside of the grinding chamber 335 through the air duct 3313, the air box 3311 and multiple connecting grooves 3312. This allows the debris generated during grinding to be collected inside the grinding chamber 335, preventing the debris generated during grinding from flying to the workers and the surrounding environment, reducing the processing risk. Moreover, with the sealing effect of the lifting clamps 3361 and the supporting bar 3362, it is difficult for the debris generated during grinding to enter the conveying chamber 332 and damage the conveying rollers 334. Compared with the traditional grinding structure, the design in this device can extend the working life.
[0036] Working principle: The flat metal part 12 to be bent and cut is inserted into the metal conveying mechanism 11. After being conveyed in the forward direction by the metal conveying mechanism 11, the end of the flat metal part 12 extends from the groove of the positioning fixture 13 into the interior of the positioning conveyor 4. As the flat metal part 12 continues to be conveyed, the end of the flat metal part 12 will be bent inside the bending device 2. At this time, the positioning conveyor 4 and the bending device 2 can be moved, thereby allowing the positioning conveyor 4 and the bending device 2 to disengage from the end of the bent flat metal part 12. Through the reverse conveying of the metal conveying mechanism 11, the end of the bent flat metal part 12 is brought closer to the positioning fixture 13 until the cutting point is below the lifting cutting member 5. At this time, the extension of the telescopic member 32 clamps the part. The grinding part 33 moves toward the flat metal part 12, so that the flat metal part 12 is inserted into the conveying chamber 332 through the feeding chamber 333 for positioning. At this time, both ends of the flat metal part 12 near the cutting position are clamped and positioned. Then, it is cut by the lifting cutting part 5. This type of cutting will not cause the metal end to lack effective support, resulting in a suspended state that causes violent vibration and displacement at the moment of cutting, causing quality defects such as slanted cut and burr growth. After the flat metal part 12 is cut, it forms a bent part and an initial part that has not yet been bent. At this time, the end of the bent part is inside the mechanism block 331, while the initial part is inside the metal conveying mechanism 11 and the positioning fixture 13. The initial part is conveyed by the metal conveying mechanism 11. The end of the bent part enters the nearest conveying chamber 332. Simultaneously, the two conveying chambers 332 at the end of the bent part transport it into another set of conveying chambers 332. At this point, both cut surfaces are inside the grinding chamber 335. The two cut surfaces of the flat metal part 12 are then ground using the structure within the grinding chamber 335, thus completing the combined bending, cutting, and grinding process. This avoids the problem of sharp burrs exposed during concentrated grinding after bending and cutting scraping the conveyor belt and surrounding equipment, and the resulting metal debris scattering and polluting the work environment. It also prevents the oxide layer from tightly bonding with the burrs after prolonged storage, significantly reducing the risk of subsequent grinding. The difficulty and cost of grinding significantly impact product surface quality and production continuity. After grinding, the telescopic component 32 retracts, causing the clamped grinding component 33 to move away from the flat metal component 12. The cut-off bent component is then removed, while the remaining initial component continues the next bending and cutting operation. After the flat metal component 12 is cut, it is further conveyed by the metal conveying mechanism 11 and multiple conveying rollers 334, ensuring that both cut surfaces of the flat metal component 12 enter the mechanism block 331. At this point, one end of the bent component formed after cutting the flat metal component 12 is inside one set of conveying cavities 332, while the other end of the cut initial component is inside another set of conveying cavities 332. In other words, both cut surfaces are inside the grinding cavity 335.Under the lifting action of the lifting clamp 3361, the lifting clamp 3361 descends and abuts against the upper part of the bent part or initial part corresponding to its position. At this time, the receiving strip 3362 below the lifting clamp 3361 supports the lower part of the corresponding bent part or initial part. That is, the setting of the two lifting clamps 3361 and the receiving strip 3362 can further position the two cut surfaces, thereby facilitating subsequent grinding and avoiding the problem of displacement and vibration of the cut surfaces of the flat metal part 12 at the beginning of subsequent grinding work. When the two cut surfaces of the flat metal part 12 are further clamped and positioned... Subsequently, the movable mechanism 337, driven by electricity, moves the movable motor 3391, the linkage box 339, and the grinding assembly 338 toward the two cutting surfaces. Simultaneously, the movable motor 3391 drives its output shaft, transmission shaft 3393, and transmission ring 3392 to rotate, which in turn drives the connecting column 3382 and the two grinding wheels 3381 to rotate at high speed. At this time, the two moving and high-speed rotating grinding wheels 3381 grind the two cutting surfaces respectively, completing the combined processing of bending and cutting of thicker metal flat plates and grinding of the cut surfaces.
