[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The purpose of this utility model is to provide a punching device to solve the problems existing in the prior art, reduce manual input, and complete the punching of the profile plate surface and both ends with one automatic machine, as well as the printing operation, with a high degree of automation.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1-10As shown, this utility model provides a punching device, including a belt conveyor mechanism 1, a feeding mechanism 2, a transferring mechanism 3, a punching mechanism 4, an end punching mechanism 4, and a printing mechanism 6, all mounted on a device platform. The U-shaped material 9 to be punched is placed on the belt conveyor mechanism 1. The feeding mechanism 2 is used to feed the U-shaped material 9 from the belt conveyor mechanism 1 to the transferring mechanism 3. The transferring mechanism 3 is used to drive the U-shaped material 9 through the punching mechanism 4, the end punching mechanism 4, and the printing mechanism 6 in sequence before dropping it off.

[0032] In one embodiment, the belt drive mechanism includes two drive belts, such as Figure 1 As shown, two transmission belts are located at the two ends of the U-shaped profile 9. The two transmission belts move synchronously to support and transport the U-shaped profile 9 to a position close to the feeding mechanism 2. Then, the feeding mechanism 2 transfers the U-shaped profile 9 to the transfer mechanism 3.

[0033] In one embodiment, the feeding mechanism 2 includes a feeding frame 21, a gripper cylinder 22, and a feeding moving component. The feeding frame 21 is fixed on the equipment platform, and the feeding moving component is installed on the feeding frame 21 and is used to drive the gripper cylinder 22 to move back and forth and up and down. The gripper cylinder 22 is used to feed the U-shaped material 9 on the belt conveyor mechanism 1 to the transfer mechanism 3. The feeding moving assembly includes a feeding support frame 27, a feeding moving frame 26, and a feeding plate 25. The feeding support frame 27 is horizontally placed on the top of the feeding frame 21. The feeding moving frame 26 is mounted on the feeding support frame 27. One end of the feeding plate 25 is movably mounted on the feeding moving frame 26 via a front and rear feeding cylinder 23, and the other end of the feeding plate 25 is movably mounted on the feeding moving frame 26 via a slide rail 33. An upper and lower feeding cylinder 24 is installed on the feeding plate 25. The telescopic ends of the upper and lower feeding cylinders 24 pass through the feeding plate 25 and are connected to the feeding rod where two gripper cylinders 22 are located. The gripper cylinders 22 mounted at both ends of the bottom of the feeding rod are used to clamp the U-shaped material 9. Clamping seats 28 are respectively provided on both sides of the bottom of the gripper cylinders 22 between the feeding frames 21.

[0034] like Figures 2-3As shown, the base of the feeding frame 21 is fixed to the platform surface of the equipment with bolts. A feeding support frame 27 is horizontally mounted on the top of the two feeding frames 21. The two ends of the feeding support frame 27 can also be fixed to the feeding frame 21 with bolts. The feeding moving frame 26 is fixed to the middle position of the feeding support frame 27 with bolts. One end of the feeding plate 25 is connected to the telescopic rod of the front and rear feeding cylinders 23 via a linkage block. The telescopic rods of the front and rear feeding cylinders 23 extend and retract, causing one end of the feeding plate 25 to move back and forth relative to the feeding moving frame 26. The other end of the feeding plate 25 moves back and forth together with the sliding rail 33. The upper and lower feeding cylinders 24 on the feeding plate 25 extend and retract, causing the feeding rod to move up and down. The gripper cylinder 22 can be in the form of an inner gripper. The two inner grippers of the gripper cylinder 22 press and hold the two side walls of the U-shaped material 9 respectively, driving the U-shaped material 9 to move up and down and back and forth, completing the transfer of the U-shaped material 9 from the belt conveyor mechanism 1 to the clamping seat 28. The bracket 32 ​​of the transfer mechanism 3 extends to the bottom of the two clamping seats 28. As the bracket 32 ​​moves up and down, the U-shaped material 9 enters the transfer mechanism 3 for the punching station.

[0035] In one embodiment, such as Figure 4 As shown, the material transfer mechanism 3 includes front and rear material transfer cylinders 31, a bracket 32, a lifting cylinder 34, a support plate 36, and a fixed frame 35. The cylinder base of the front and rear material transfer cylinders 31 is mounted on the platform of the equipment platform, and the telescopic rod of the front and rear material transfer cylinders 31 is connected to the fixed frame 35. The two ends of the fixed frame 35 are respectively equipped with support plates 36, and the bottom of the support plates 36 is slidably mounted on the platform of the equipment platform via slide rails 33. The top of the support plates 36 is provided with a bracket 32, and the lifting cylinder 34 is used to drive the bracket 32 ​​to rise and fall relative to the support plates 36. U-shaped grooves are provided at intervals on the bracket 32.

[0036] The U-shaped grooves on the two side brackets 32 can be staggered or corresponding. The frontmost side of the equipment platform is provided with a feeding mechanism 7, which includes a feeding platform and a feeding guide plate. The movement limit position of the fixed frame 35 in the transfer mechanism 3 is when it moves forward to the feeding platform. During the lifting process of the lifting cylinder 34, the U-shaped material 9 is lifted from the clamping seat 28 of the feeding mechanism 2, so that the two side brackets 32 support the U-shaped material 9. Then the front and rear transfer cylinders 31 move, driving the U-shaped material 9 into the punching mechanism 4, the end punching mechanism 4 and the printing mechanism 6 in sequence. After printing, the fixed frame 35 moves to the limit position close to the feeding platform. The front end of the two side brackets 32 extends out of the fixed frame 35. Therefore, the lifting cylinder 34 lifts the U-shaped material 9, and the U-shaped material 9 will fall onto the feeding platform. Then, through the push of the feeding cylinder, the U-shaped material 9 is discharged from the feeding guide plate.

[0037] In one embodiment, the punching mechanism 4 includes a punching frame 41, punching components and a mold base 45; the punching frame 41 is set on the equipment platform and located between the feeding mechanism 2 and the end punching mechanism 4, and three sets of punching components are equally spaced on the top of the punching frame 41, and a mold base 45 is correspondingly provided at the bottom of each set of punching components.

[0038] The punching assembly includes a punching cylinder 42, a punching plate 43, and punching heads 44. The punching cylinder 42 is fixed on the top of the punching machine frame 41. The end of the telescopic rod of the punching cylinder 42 is equipped with the punching plate 43. Multiple punching heads 44 are arranged at equal intervals on the punching plate 43. The U-shaped material 9 is placed on the mold base 45.

[0039] A positioning cylinder 48 is provided at any end of the U-shaped profile 9 between the punching machine frames 41. The positioning cylinder 48 is used to contact the end of the U-shaped profile 9 to provide positioning for the U-shaped profile 9. A clamping cylinder 47 is also provided at both ends of the U-shaped profile 9 between the punching machine frames 41. The clamping cylinder 47 is used to clamp the end of the U-shaped profile 9.

[0040] like Figures 5-7 As shown, during the lifting process of the lifting cylinder 34, the U-shaped material 9 is lifted from the clamping seat 28 of the feeding mechanism 2, so that the brackets 32 on both sides support the U-shaped material 9. Then, the forward and backward moving cylinder 31 moves, driving the U-shaped material 9 into the punching mechanism 4 in sequence. When the U-shaped material 9 moves to the position of the U-shaped seat 46 on the punching die 57, the lifting cylinder 34 falls down, and the U-shaped material 9 falls into the U-shaped seat 46. At the same time, the positioning cylinder 48 extends and retracts to the set length and contacts the end of the U-shaped material 9. This ensures the positioning of the U-shaped material 9, making the punching position more accurate. The clamping cylinders 47 at both ends clamp the U-shaped material 9, and the punching cylinder 42 drives the punching plate 43 to move downward. The punching head 44 at the bottom of each punching plate 43 completes the punching of the U-shaped material 9. In order to ensure the stability of the movement of the punching plate 43, a telescopic air rod can also be set between the top of the punching plate 43 and the top support of the punching frame 41 to assist the operation.

[0041] In one embodiment, such as Figures 8-9 As shown, the end punching mechanism 4 includes an end punching support frame 51, an end punching cylinder 42, a V-shaped moving block 58, and a punching die 57. The end punching support frame 51 is slidably arranged at both ends of the U-shaped profile 9 on the equipment platform. The front and rear cylinders are used to drive the end punching support frame 51 to move back and forth. An end punching support plate 53 is provided on the end punching support frame 51. The end punching cylinder 42 is installed on the end punching support plate 53. The telescopic rod of the end punching cylinder 42 passes through the end punching support plate 53 and is connected to the V-shaped moving block 58. The V-shaped moving block 58 is used to drive the two punching dies 57 to punch the ends of the U-shaped profile 9.

[0042] The top of the end punching mechanism 4 is equipped with a clamping cylinder 55 via a mounting plate 54. The mounting plate 54 is fixedly installed on the top frame of the equipment platform. The clamping cylinder 55 is used to clamp the end of the U-shaped profile 9 to facilitate end punching.

[0043] The V-shaped moving block 58 includes a main body and symmetrical inclined connecting blocks located on both sides of the main body. A groove is provided on the inclined surface of the inclined connecting blocks. The side of the punching die 57 is slidably assembled with the groove via a clamping block 56. The punching die 57 is mounted on the outer extension arm on the front side of the end punching support plate 53. A groove is provided on the inner side of the outer extension arm. The outer side of the punching die 57 is slidably assembled in the groove on the inner side of the outer extension arm via a compression spring. In this way, the punching die 57 can move forward and inward relative to the outer extension arm. The compression spring serves both as a connector and as a sliding element with the punching die 57. Since the range of motion of the punching die 57 is small, the compression spring is sufficient. Of course, to improve connection and movement stability, other components with telescopic and sliding capabilities can be used instead. During end punching, the telescopic rod of the end punching cylinder 42 extends forward, causing the V-shaped moving block 58 to move forward between the two outer arms on the front side of the end punching support plate 53. Due to the wedge-shaped end face of the inclined connecting block, the punching dies 57 on both sides will move inward and forward to complete the punching of both sides of the profile end. After the end punching is completed, the end punching cylinder 42 retracts, driving the punching die 57 to move backward.

[0044] In one embodiment, such as Figure 10 As shown, the printing mechanism 6 includes a pneumatic-hydraulic booster cylinder 61 and a printing mold 62. The printing mold 62 is set on one side of the U-shaped material 9 on the equipment platform. The printing mold 62 is located at the next station after the end punching mechanism 4. The top of the printing mold 62 is equipped with a pneumatic-hydraulic booster cylinder 61, which is used to press the U-shaped material 9 downward to complete the model printing. The station of the printing mechanism 6 is equipped with a clamping seat 28 and a clamping printing cylinder 63. The U-shaped material 9 is raised and lowered at the printing mechanism 6 along with the bracket 32 ​​of the material transfer mechanism 3. The U-shaped material 9 is placed in the clamping seat 28 of the printing mechanism 6. Then the clamping printing cylinder 63 clamps the printing end of the material, and the pneumatic-hydraulic booster cylinder 61 completes the downward pressing and pressing printing.
