Description

Technical Field

[0001] This invention relates to the field of machining equipment technology, and in particular to a fully automatic cutting, punching and tapping integrated machine. Background Technology

[0002] Currently, machining in industrial production is primarily done manually. Workers operate cutting machines, punch presses, and tapping machines, using simple clamps to perform cutting, punching, and tapping operations. These machines require workers to be constantly at the machine stations, operating the cutting machine for cutting and the punch press and tapping machine for punching and tapping. This results in high labor intensity and inherent safety risks for workers.

[0003] Since the work is primarily done manually, the following problems exist:

[0004] 1. High labor intensity. When there are many orders, workers need to work overtime and for long hours. Because their hands and feet are constantly moving, workers are often exhausted.

[0005] 2. The work involves certain risks. Because the work is done manually, there are opportunities for workers' hands to come into close contact with molds and tooling, or even to penetrate deep into the molds. Accidents may occur when workers are fatigued.

[0006] 3. Quality is difficult to guarantee. Due to manual operation, quality is controlled by humans. Workers are frequently rotated, making it difficult to ensure that quality requirements are met, thus the yield rate cannot be guaranteed. In particular, new workers may not fully understand the quality requirements, which can lead to certain quality deviations. Summary of the Invention

For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0061] refer to Figures 1-13 This embodiment provides a fully automatic cutting, punching, and tapping integrated machine, mainly used for cutting, punching, and tapping a whole raw material 10. In this embodiment, it is mainly used for processing machine parts. The raw material 10 includes an upper concave cavity 101, a lower concave cavity 102, two upper sidewalls 103 forming the upper concave cavity 101, and two lower sidewalls 104 forming the lower groove 131. The two lower sidewalls 104 extend to both sides to form lower steps 105. The fully automatic cutting, punching, and tapping integrated machine includes a central control system, a cooling water tank assembly 8, and components arranged sequentially along the workpiece processing sequence.

[0062] The first process is material preparation and loading. A material preparation rack assembly 1 is set up, including a transport channel 11 and a pusher 12. The transport channel 11 has at least two transport lines spaced apart along its width. The transport channel 11 is responsible for fixing the raw material 10 within its width position. The pusher 12 then pushes the raw material 10 along the length of the transport channel 11 to the next process step.

[0063] The transport channel 11 is provided with a plurality of drive wheels 13 spaced apart along its length, and the drive wheels 13 are provided with a plurality of grooves 131 spaced apart along the width of the transport channel 11. The plurality of drive wheels 13 and the plurality of grooves 131 arranged in a straight line along the length of the transport channel 11 form a transport line. A whole raw material 10 is placed on the transport line. The drive wheels 13 can be configured as unpowered driven wheels or as powered driving wheels, and the drive wheels 13 serve to roll and transport the raw material 10.

[0064] The pushing component 12 includes a pushing cylinder 121 and a pushing plate 122. A pushing block 123 and a pushing block 124 are provided on both sides of the pushing plate 122. The pushing block 123 is located inside the pushing plate 122 along the pushing direction and is connected to the pushing plate 122 by an elastic element 125. The pushing blocks 124 are located outside the pushing plate 122 along the pushing direction. The pushing plate 122 moves along the pushing direction under the action of the pushing cylinder 121 and pushes the raw material 10 placed on the conveyor line to the next process with the pushing block 123 and the pushing block 124.

[0065] The pusher 12 has several push blocks 123 and 124 arranged on the inner and outer sides of the pusher plate 122. Each set of push blocks includes one push block 123 and one push block 124. A set of push blocks is arranged corresponding to each groove 131 along the length of the transport channel 11. The push blocks 123 and 124 are respectively engaged in the upper concave cavity 101 of the raw material 10. The pusher plate 122 has a channel corresponding to the push blocks for the raw material 10 to pass through and be transported. The push blocks 123 and 124 are in frictional engagement with the upper concave cavity 101 of the raw material 10, and the frictional force is used to push the raw material 10. The elastic element 125 between the push block 123 and the pusher plate 122 is a spring, which provides cushioning during the pushing process.

[0066] The second process is feeding and retraction. The feeding unit 2 includes a feeding guide rail 21 and a clamping device 22. The clamping device 22 is driven by a clamping power unit 23 to clamp the raw material 10 and moves back and forth along the length of the feeding guide rail 21, feeding the raw material 10 to or from the next process. When the clamping device 22 clamps the raw material 10 and pushes it to the next process, the pushing member 12 in the first process can be set to synchronously push to assist the power, or the pushing member 12 can not push, but utilize the deformation of the elastic element 125 on a push block 123 to assist the pushing of the clamping device 22. It should be noted that after the clamping device 22 clamps the raw material 10, the pushing member 12 has a reset action. The raw material 10 remains stationary under the clamping of the clamping device 22, and the pushing member 12 retracts to the starting position under the drive of the pushing cylinder 121, ready for the next pushing operation.

[0067] The clamping device 22 includes a movable seat 221 and a plurality of clamping members disposed on the movable seat 221. One clamping member is disposed corresponding to one of the transport lines. The movable seat 221 is slidably connected to the feeding guide rail 21. The clamping members are disposed towards the cutting and pressing group 3. The movable seat 221 is provided with a plurality of feeding channels 227 on the side facing the material preparation rack group 1, so that the raw material 10 pushed by the first process can pass through to the position of the clamping member for clamping. One feeding channel 227 is disposed corresponding to one of the clamping members.

[0068] The clamping component includes an upper clamping component 222 and a lower clamping component 223. The upper clamping component 222 and the lower clamping component 223 are driven by the clamping power unit 23 to move closer or further apart. A sensor 224 is provided between the upper clamping component 222 and the lower clamping component 223. The sensor 224 is located at the upper end of the extended channel of the feed channel 227. When the sensor 224 senses that the raw material 10 is pushed to the position of the clamping component, after a certain period of sensing, the system controls the clamping power unit 23 to drive the upper clamping component 222 and the lower clamping component 223 to move closer together to clamp the raw material 10. The time period is set according to the pushing speed of the raw material 10. After a certain period of time, it is ensured that the distance of the raw material 10 pushed out and beyond the clamping component is sufficient for the next processing step. It should be noted that in this embodiment, the clamping components are configured as symmetrical clamping structures, or they can be configured as single-sided clamping. That is, one of the upper clamping component 222 and the lower clamping component 223 is configured as a fixed component 225, and the other is configured as a movable component 226. The configuration can be adjusted accordingly based on production requirements.

[0069] Both the upper clamping member 222 and the lower clamping member 223 include a fixed member 225 and a movable member 226. The movable member 226 has elasticity relative to the fixed member 225. The movable members 226 of the upper clamping member 222 and the lower clamping member 223 are arranged opposite to each other. The movable member 226 has a built-in spring. When it is clamped close to the material 10, the force acting on the clamping surface of the material 10 has a certain buffering force, which can avoid damage to the material 10.

[0070] The movable seat 221 is driven by a hydraulic cylinder, a pneumatic cylinder, or a servo motor and slides along the track line of the feeding guide rail 21. The clamping power unit 23 uses compressed air as power. After the upper clamping member 222 and the lower clamping member 223 are symmetrically clamped by the pneumatic cylinder, the movable seat 221 drives the clamping member to feed the material to the next process. The material 10 on the material rack group 1 is fed into the next process for processing while keeping the center position unchanged according to the required length.

[0071] Since the next process involves cutting, a retraction process is set in the second process. After the cutting is completed, the retraction on that side is performed first, that is, the moving seat 221 is moved away, and the clamping part is used to retract the raw material 10 on that side to prevent the cutting blade from scratching the cutting surface.

[0072] The third process involves pressing and cutting the raw material 10. The cutting and pressing assembly 3 includes a pressing component and a cutting machine 34. The pressing component includes a first pressing assembly 31 and a second pressing assembly 32. A space is provided between the first pressing assembly 31 and the second pressing assembly 32 for the cutting machine 34 to work in. The first pressing assembly 31 is located close to the clamping device 22 and is fixedly installed. The second pressing assembly 32 is movable relative to the first pressing assembly 31. This movable arrangement of the second pressing assembly 32 is used for retracting the blade on the other side of the cut after the cutting is completed, and this retraction process is performed simultaneously with the retraction process of the moving seat 221 in the second process. The cutting machine 34 is driven by a motor for rotation and a servo motor for feed motion, driving the cutter to cut the material to the length required by the drawing. The cutting power of the cutting machine 34 can be set to servo power, hydraulic cylinder drive, or pneumatic cylinder drive.

[0073] The clamping components include a track assembly and a drive cylinder. A movable stage 33 is slidably mounted on the track assembly, and the two clamping components are mounted on the movable stage 33. The movable stage 33 is driven by the drive cylinder to move closer to or away from the first clamping component along the track assembly. When the two clamping components are close to the first clamping component, they are in the cutting process, and a fixed distance is set between the two clamping components and the first clamping component. Within this distance gap 318, a space is formed for the cutting activity of the cutting machine 34. The two clamping components are used to place and move the cut raw material 10, and to act on the retraction of the cut raw material 10. The first clamping component is used to place the raw material 10, and to feed the raw material 10 and perform retraction operations on the feeding group 2.

[0074] Both the first clamping group 31 and the second clamping group 32 include an upper clamping member 311, a lower clamping member 312, and a clamping power unit 313. In the relative positions of the upper clamping member 311 and the lower clamping member 312, the lower clamping member 312 is fixed, and the upper clamping member 311 is driven by the clamping power unit 313 to move vertically towards or away from the lower clamping member 312. The upper clamping member 311 and the lower clamping member 312 are correspondingly provided with several upper clamping stations 314 and lower clamping stations 315, with one upper clamping station 314 corresponding to one lower clamping station 315. Each transport line is correspondingly provided with one set of the upper clamping stations 314 and lower clamping stations 315.

[0075] The lower pressing station 315 and the lower pressing member 312 are respectively recessed to form cavities, and protrusions 316 are provided in the cavities. The lower pressing station 315 forms grooves 317 on both sides of the protrusions 316 with the cavity. The upper pressing station 314 forms gaps 318 on both sides of the protrusions 316 with the cavity. The raw material 10 has an upper concave cavity 101, a lower concave cavity 102, two upper sidewalls 103 forming the upper concave cavity 101, and two lower sidewalls 104 forming the lower groove 131. The two lower sidewalls 104 extend to both sides to form lower steps 105. During pressing, the protrusions 316 of the lower pressing station 315 and the lower pressing member 312 are respectively placed in the lower concave cavity 102 and the upper concave cavity 101, the upper sidewalls 103 are inserted into the gaps 318, and the lower steps 105 are placed in the grooves 317.

[0076] The fourth process is the punching assembly 4. The punching assembly 4 includes a punching machine 41, used to punch threaded holes in the cut material according to the drawing requirements. The punching power of the punching machine 41 can be set to a hydraulic or pneumatic-hydraulic booster cylinder or a pneumatic cylinder.

[0077] The fifth process is the tapping assembly 5. The tapping assembly 5 includes a tapping machine 51, which uses a servo motor for rotational power and a lead screw to determine the lead stroke, tapping the material with punched bottom holes according to the drawing requirements. The tapping head of this tapping machine 51 can also be configured to use a stepper motor for rotational motion, pushed to the working position by a cylinder.

[0078] This embodiment includes a material transfer group 7 and a tooling group for transporting and placing the cut raw material 10 between each process.

[0079] Specifically, several tooling fixtures 6 are evenly spaced between the cutting and clamping group 3, the punching group 4, and the tapping group 5 to hold the cut raw materials 10, and are divided into tooling fixture 61, tooling fixture 62, tooling fixture 63, and tooling fixture 64. Tooling fixture 62 is located below the punching group 4 and is used to hold the cut raw materials 10 to be punched for the punching process. Tooling fixture 64 is located below the tapping group 5 and is used to hold the cut raw materials 10 to be tapped for the tapping process. Tooling fixture 61 and tooling fixture 63 are respectively located between the cutting and clamping group 3 and the punching group 4, and between the punching group 4 and the tapping group 5. Each tooling fixture 6 includes several processing positions 65, and one processing position 65 is provided for each of the transport lines. Each processing position 65 includes a limiting member 66 to restrict the forward and backward movement of the cut raw materials 10.

[0080] A material transfer group 7 is provided between the cutting and clamping group 3, the punching group 4 and the tapping group 5. The material transfer group 7 is powered by a servo motor, which makes the nut rotate on the screw to move a distance. The material is moved to the next process by the gripping of the air gripper.

[0081] Specifically, the material transfer group 7 includes a first material transfer group 71, a second material transfer group 72, and a third material transfer group 73; a discharge position 67 is provided after the tapping group 5; the first material transfer group 71 is located between the cutting and pressing group 3 and the punching group 4, the second material transfer group 72 is located between the punching group 4 and the tapping group 5, and the third material transfer group 73 is located between the tapping group 5 and the discharge position 67; the first material transfer group 71, the second material transfer group 72, and the third material transfer group 73 are driven synchronously by the same power.

[0082] The first transfer group 71 has a first moving position and a second moving position. At the first moving position, it is used to acquire the cut raw material 10 from the two clamping parts, and also to acquire the cut raw material 10 when it is on the tooling 61. At the second moving position, it is used to place the acquired cut raw material 10 onto the tooling 61 and the tooling 62. The second transfer group 72 has a third moving position and a fourth moving position. At the third moving position, it is used to acquire the cut raw material 10 from the tooling 62 and the tooling 63. At the fourth moving position, it is used to place the acquired cut raw material 10 onto the tooling 63 and the tooling 64. The third transfer group 73 has a fifth moving position and a sixth moving position. At the fifth moving position, it is used to acquire the cut raw material 10 from the tooling 64. At the sixth moving position, it is used to place the acquired cut raw material 10 to the unloading position 67.

[0083] The material transfer group 7 includes a material transfer guide rail 74 and at least one material picker 75. The material picker 75 moves back and forth along the length of the material transfer guide rail 74 to transfer the cut raw material 10 to the next process. The first material transfer group 71 and the second material transfer group 72 are involved in the transportation and unloading of the raw material 10. Therefore, both the first material transfer group 71 and the second material transfer group 72 include two material pickers 75 and a moving frame 76 that houses the two material pickers 75. The two material pickers 75 are evenly spaced from the workstations. The moving frame 76 is slidably connected to the material transfer guide rail 74. The back-and-forth movement of the moving frame 76 drives the two material pickers 75 to simultaneously acquire or place the raw material 10 on two tooling fixtures 6. The three material transfer group 73 is equipped with a material picking component 75 and a moving frame 76 for the material picking component 75. After the material picking component 75 picks up the raw material 10 at the four tooling 64, it moves to the unloading position 67 to directly unload the material. Therefore, only one material picking component 75 needs to be set up.

[0084] The material handling component 75 includes a material handling gripper, and one set of material handling grippers is provided for each processing position 65. The material handling gripper includes a first gripper 751, a second gripper 752, and a gripper power unit 753 arranged on the left and right sides respectively. The first gripper 751 and the second gripper 752 each have a first-level step 754 and a second-level step 755 on opposite sides. When the material handling gripper clamps the cut raw material 10, the end face of the first-level step 754 abuts against the end face of the clamping end of the cut raw material 10, and the second-level step 755 is placed in the upper concave cavity 101 of the clamping end of the cut raw material 10. It should be noted that in this embodiment, the gripper can be replaced by a vacuum suction cup for material handling.

[0085] In this embodiment, a cooling water tank assembly 8 and a hydraulic station assembly are also included. The cooling water tank assembly 8 provides cooling water for the punching and tapping processes, ensuring the smooth operation of these processes. The hydraulic station assembly provides a pressure source for the cylinders used in the punching and tapping processes. A tailings and waste outlet 9 is provided below the feeding assembly 2 of the entire machine. The entire machine has a built-in tailings and waste collection channel, which receives the waste produced by each assembly during operation and collects it at the tailings and waste outlet 9 for recycling. On the entire machine, the central control system includes sensors distributed to each assembly. Multiple sensors can accurately sense the working status of each process, and workers only need to hear abnormal sounds from the sensors to troubleshoot the problem.

[0086] The fully automatic cutting, punching, and tapping machine provided in this embodiment operates as follows: The entire raw material 10 is placed on the material preparation rack group 1 and pushed to the feeding group 2; then the feeding group 2 feeds the raw material 10 into the cutting group according to the required length, and after being pressed by the cutting and clamping group 3, it is cut by the cutter of the cutting group; after cutting, the feeding group 2 and the second clamping group 32 perform a retraction action to prevent the cut surface of the material from being scratched by the cutter, and then the cutter returns to the standby position; the cut material is transferred by the first transfer group 71 to the second tooling position 62 of the punching group 4, and the hydraulic cylinder, under the power provided by the hydraulic station, pushes the mold to punch the bottom hole of the raw material 10 according to the drawing position; the punched material is then transferred by the second transfer group 72 to the tapping group 5, and the automatic tapping machine 51 drives the tap to tap the material, while cooling water is used for lubrication and cooling; the tapped material is then taken out from the fourth tooling position 64 by the third transfer group 73 and transferred to the unloading position 67 for unloading.

[0087] The above description is merely a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention by those skilled in the art within the scope of the technology disclosed in the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
