Description

Technical Field

[0001] The present invention relates to the technical field of hinge processing equipment, and in particular to a cutting device and a processing method for hinge processing. Background Art

[0002] Hinge processing equipment is a specialized machine used to process hinges and related profiles. It is widely used in door and window manufacturing, furniture production, and other applications requiring hinge assembly. A hinge is a common connector whose primary function is to enable relative rotation between two components, such as a door and doorframe. The hinge production process typically involves cutting, stamping, and bending raw materials (such as metal profiles) to meet specific size and shape requirements.

[0003] The existing technology still has many shortcomings in the cutting operation of hinge profiles. Specifically, when cutting long hinge profiles, traditional cutting equipment often requires manual feeding of the profile to the cutting machine's working position for cutting. This operation method not only poses a significant safety hazard and can easily cause operator injury, but also makes it difficult to ensure the accuracy and consistency of profile cutting. In addition, long-term manual feeding operations will significantly increase labor intensity, causing operator fatigue, and thus affecting cutting efficiency.

[0031] In order to clearly and completely describe the objectives and technical solutions of the present invention and to make the advantages more clearly understood, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figures 1 to 6 The present invention provides a technical solution: an adjustment component and a bag dust removal device, comprising: a processing table 1, the processing table 1 is the main body of the entire device, a limit block 2 is fixedly installed on the upper surface of the processing table 1, and a profile groove is opened on the limit block 2 to limit the profile. A feeding component is provided on one side of the processing table 1, and the feeding component is used to feed the profile. A clamping component is installed on one side of the feeding component, and the clamping component clamps the profile to achieve feeding. The feeding component includes a rotatably installed cam plate 3, and a turntable 4 is fixedly installed on one side of the cam plate 3. Through the cam The rotation of the disk 3 drives the turntable 4 to rotate. A U-shaped frame 5 is provided on one side of the turntable 4. A limit rod 6 is provided on the sliding sleeve of the U-shaped frame 5. The clamping assembly includes a driving plate 7. The driving plate 7 can rotate. The two ends of the driving plate 7 are rotatably connected to the transmission plate 8. A clamping plate 9 is rotatably installed on one end of the transmission plate 8. One end of the clamping plate 9 is slidably connected to the limit plate 10. The limit plate 10 limits the clamping plate 9 so that it can move laterally. A pneumatic cutting machine 11 is provided on one side of the clamping assembly. The setting of the pneumatic cutting machine 11 facilitates cutting of the processing profiles of the hinge.

[0033] Place the hinge processing profile on the processing table 1, and make one end of it pass through the limit blocks 2 on both sides of the cam disc 3, so as to initially limit the profile. Then, by driving the rotation of the cam disc 3, the turntable 4 is driven to rotate, and the turntable 4 thereby drives the U-shaped frame 5 to move. Under the trajectory of the cam disc 3 and the limit of the U-shaped frame 5, the limit rod 6 can realize the up and down oblique movement, so that the limit rod 6 drives the clamping assembly to move forward and backward. When the clamping assembly moves forward, the drive plate 7 rotates, and the transmission plate 8 Under the transmission action of the two clamping plates 9, the two clamping plates 9 move toward each other under the limit of the limit plate 10, thereby clamping the profile, thereby realizing clamping and feeding, and the material is conveyed to the bottom of the pneumatic cutting machine 11, and then the profile is cut. When the clamping assembly retreats, the driving plate 7 moves in the opposite direction, so that the clamping plate 9 no longer clamps the profile. This reciprocating process can realize uninterrupted feeding of the profile, avoiding the trouble of manual feeding, not only improving the processing accuracy, but also reducing labor intensity and improving processing efficiency.

[0034] Example 2: On the basis of Example 1, three limit blocks 2 are provided, and the three limit blocks 2 are arranged linearly with respect to the upper surface of the processing table 1. By setting the limit blocks 2, the stability of the profile during the feeding process and the stability during the cutting process are ensured. The lower surface of the processing table 1 is fixedly connected to a support column 12, and the support columns 12 are arranged in a linear array. The support columns 12 stably support the entire processing table 1. Two support platforms 13 are fixedly connected to the side wall of the processing table 1. A pneumatic cutting machine 11 is fixedly installed on the upper surface of one of the support platforms 13. The position of the processing table 1 close to the pneumatic cutting machine 11 is A knife unloading groove is provided at the position to facilitate the exit of the cutting disc. The upper side of the other support platform 13 is fixedly connected to the bottom of the reduction box 15 through a support rod 14. The setting of the reduction box 15 avoids feeding too fast, thereby ensuring processing accuracy. The input end of one side of the reduction box 15 is fixedly connected to the output end of the feeding motor 16, and the output end of the other side of the reduction box 15 is fixedly connected to one end of the rotating shaft 17 through a coupling. The other end of the rotating shaft 17 is fixedly connected to one side of the cam disc 3. The other side of the cam disc 3 is fixedly connected to the turntable 4 through a bolt 18. One side of the turntable 4 is fixedly connected to a limit pin 19. The U-shaped frame 5 is sleeved on the limit pin 19 and is rotatably connected with the limit pin 19. The limit pin 19 limits the U-shaped frame 5, so that the U-shaped frame 5 can rotate on one side of the turntable 4. The middle part of the rotating shaft 17 is rotatably sleeved on the support frame 20 and is rotatably connected with the top of the support frame 20. The support frame 20 limits the rotating shaft 17. A fixed rod 21 is fixedly connected to the bottom of the support frame 20. A roller 22 is rotatably sleeved on the fixed rod 21. The fixed rod 21 limits the roller 22. The outer ring surface of the cam disc 3 is slidably connected to the roller 22. A first protrusion is provided on one side of the outer ring surface of the cam disc 3 23, the first protrusion 23 is close to the bolt 18, and the second protrusion 24 is provided on the other side of the outer ring surface of the cam disc 3, and the second protrusion 24 is away from the bolt 18; the fixing sleeves on both sides of the limit rod 6 are provided with limit rings 25, and the limit rings 25 limit the limit rod 6 on the U-shaped frame 5. A buffer spring 26 is fixedly connected between one of the limit rings 25 and the U-shaped frame 5, and the buffer spring 26 buffers the limit rod 6, thereby preventing the clamping assembly from pushing the profile too hard and causing damage to the profile. A support plate 27 is welded and fixed at one end of the limit rod 6, and the support plate 27 is used to stably support the clamping assembly.

[0035] When the profile passes through the limit blocks 2 on both sides of the cam disc 3, in order to achieve continuous feeding, the feeding motor 16 is started, and the output end of the feeding motor 16 is connected to the input end of the reduction gear 15, thereby driving the rotating shaft 17 to rotate under the limit of the support frame 20 through the output end of the reduction gear 15, and the rotating shaft 17 then drives the cam disc 3 to rotate, and the bottom of the cam disc 3 is slidably connected to the roller 22, thereby improving the rotation stability of the cam disc 3, and the cam disc 3 drives the turntable 4 to rotate through the connection of the bolts 18, and the turntable 4 drives the fixed rod 21 fixed thereon to rotate synchronously, and under the rotation cooperation of the fixed rod 21 and the U-shaped frame 5, when the first protrusion 23 of the cam disc 3 approaches the upper surface of the processing table 1 from the direction away from the processing table 1, the fixed rod 21 pushes up the U-shaped frame 5, and When the first protrusion 23 moves away from the upper surface of the processing table 1 again, the fixing rod 21 pulls the U-shaped frame 5 in the direction away from the pneumatic cutting machine 11 to facilitate the next feeding. When the second protrusion 24 gradually approaches the upper surface of the processing table 1, the fixing rod 21 presses the U-shaped frame 5 downward, and as the second protrusion 24 moves away from the upper surface of the processing table 1 again, at this time, under the limit of the fixing rod 21, the fixing rod 21 drives the U-shaped frame 5 to move in the direction close to the pneumatic cutting machine 11, thereby realizing one-time feeding. In this way, reciprocating feeding can be realized, and then through the connection between the limiting rod 6 and the support plate 27, the clamping assembly continues to feed the profile forward in the direction close to the pneumatic cutting machine 11 uninterruptedly, avoiding the trouble of manual operation, reducing labor intensity, and improving feeding and processing efficiency.

[0036] The third embodiment: On the basis of the second embodiment, the support plate 27 is arranged in an inclined manner, and the lower surface of the support plate 27 is welded and fixed to the limit plate 10. One side of the limit plate 10 is fixedly connected to the clamping motor 28, and the limit plate 10 stably supports the clamping motor 28. A limit slot 29 is provided on the other side of the limit plate 10, and the limit plate 10 limits the clamping plate 9. The limit slot 29 is slidably connected to one end of the clamping plate 9, and the other side of the clamping plate 9 is fixedly connected with an anti-slip soft block 30. The output end of the clamping motor 28 is fixedly connected to the middle of the driving plate 7. The two ends of the driving plate 7 are rotatably connected to one end of the transmission plate 8 by a pin shaft, and the other end of the transmission plate 8 is rotatably connected to the clamping plate 9 by a pin shaft. The side walls of the limit blocks 2 on both sides of the pneumatic cutting machine 11 are fixedly installed with electric push rods 31. The electric push rods 31 are fixedly connected to the limit blocks 2 through the connecting plate, and the output end of the electric push rods 31 is fixedly connected with a pressure block 32. The pressure block 32 squeezes and limits the profile, thereby improving the stability during profile cutting.

[0037] When the U-shaped frame 5 drives the limit rod 6 to move forward, the clamping motor 28 is started at this time, and the clamping motor 28 drives the driving plate 7 fixedly installed at its output end to rotate, and the driving plate 7 drives the transmission plate 8 to move through the rotation connection of the pin shaft. The transmission plate 8 drives the two clamping plates 9 to move toward each other under the limit of the limit groove 29 opened on the limit plate 10 under the rotation connection of the pin shaft, thereby clamping the anti-slip soft block 30 on the profile, thereby moving the profile toward the direction of the pneumatic cutting machine 11. At the same time, the output end of the electric push rod 31 extends, thereby driving the pressure block 32 to press the two sides of the profile, thereby improving the cutting stability of the pneumatic cutting machine 11. When the U-shaped frame 5 drives the limit rod 6 to move in the direction away from the pneumatic cutting machine 11, the clamping motor 28 is driven in the reverse direction, so that the clamping plate 9 no longer clamps the profile, and the electric push rod 31 moves in the reverse direction. This reciprocating process can continuously feed the profile toward the pneumatic cutting machine 11.

[0038] Example 4: Based on Example 3, the external cover of the processing table 1 is provided with a splash-proof transparent cover 33, and a controller 34 is fixedly installed on one side of the splash-proof transparent cover 33. The controller 34 is electrically connected to the pneumatic cutting machine 11, the feeding motor 16, the clamping motor 28, and the electric push rod 31. A material receiving box 35 is provided on one side of the splash-proof transparent cover 33.

[0039] The splash-proof transparent cover 33 prevents the splashing of debris during the cutting process, thereby facilitating subsequent cleaning. The controller 34 controls the various electrical components so that they work together. When the profile is continuously pushed forward, the cut profile is pushed into the material receiving box 35, thereby collecting the materials in a unified manner.
