Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-Figure 3The utility model provides an embodiment: a plate punching device for a plate heat exchanger, comprising a workbench 1, the front end of the workbench 1 is fixedly connected to a control console, a punching machine is arranged on the top of a base 2, the top of the workbench 1 is fixedly connected to a base 2, the workbench 1 here plays a supporting and fixing role for the base 2, the bottom end of the inner wall of the base 2 is fixedly connected to a motor 3, the driving end of the motor 3 is fixedly connected to a turntable 4, and the motor 3 here will drive the turntable 4 to rotate together when it rotates.

[0026] Reference Figure 2-Figure 3 The four sides of the bottom end of the turntable 4 are fixedly connected with support columns 5, and the bottom ends of the support columns 5 are slidably connected to the bottom inner wall of the base 2. The support columns 5 here can ensure the stability of the turntable 4 during rotation. The two ends of the outer wall of the turntable 4 are rotatably connected with the rotating shaft 6, and the other end of the rotating shaft 6 is rotatably connected with a rotating column 7. The outside of the rotating column 7 is slidably connected to the top inner wall of the base 2, and the top of the rotating column 7 is rotatably connected with a clamping body 8. The clamping body 8 here is used to clamp the plate, and the width spacing can be adjusted.

[0027] Reference Figure 1-Figure 3 The bottom end of the clamp body 8 is slidably connected to the top end of the base 2, and the adjacent sides of the two clamp bodies 8 are fixedly connected with rubber pads 9, where the rubber pads 9 are used to protect the plate from damage. The left and right sides of the bottom end of the clamp body 8 are fixedly connected with limit blocks 10, and two slide grooves 11 are provided on the front and back sides of the top of the base 2. The outer part of the limit block 10 is slidably connected to the inner wall of the slide groove 11, and the limit block 10 here can ensure the translational movement of the clamp body 8 when sliding in the slide groove 11, and a support component is fixedly connected to the right side of the inner workbench 1.

[0028] Reference Figure 1 and Figure 4 The support assembly includes a bottom block 12, the left side of the bottom block 12 is fixedly connected to the right side of the workbench 1, and the workbench 1 here supports the bottom block 12 to make it stable. The top of the bottom block 12 is fixedly connected to a top box 13, and the bottom left side of the top box 13 is fixedly connected to the top right side of the base 2. The front end of the support assembly is fixedly connected to a pushing assembly, and the pushing assembly here is used to push out the punched plate, reduce the time of worker intervention, and increase the punching rate.

[0029] Reference Figure 1 and Figure 4 The pushing component includes a column 14, the rear end of the column 14 is fixedly connected to the front end of the top box 13, the inner wall of the column 14 is fixedly connected with a motor 2 15, and the driving end of the motor 2 15 is fixedly connected with a bidirectional threaded rod 16. When the motor 2 15 is started, the bidirectional threaded rod 16 will drive the bidirectional threaded rod 16 to expand to both sides. The front and rear ends of the outside of the bidirectional threaded rod 16 are both threadedly connected with special-shaped blocks 17. When the bidirectional threaded rod 16 expands, it will drive the special-shaped blocks 17 to move to both sides.

[0030] Reference Figure 1 and Figure 4 The right side of the special-shaped block 17 is slidably connected to the inner wall of the top box 13, and the left side of the special-shaped block 17 is rotatably connected to the long axis 18. When the special-shaped block 17 moves, it drives the long axis 18 to rotate, thereby extending it. The other end of the long axis 18 is rotatably connected to another long axis 18, and the other ends of the two other long axes 18 are rotatably connected to a top plate 19. The top plate 19 here is used to directly contact the plate and push it out of the punching range. The bottom end of the top plate 19 is slidably connected to the top of the base 2, and the right side of the top plate 19 is in contact with the left side of the top box 13.

[0031] Working principle: When the staff uses this metal plate punching device, they can first place the plate to be punched on the surface of the base 2 at the top of the workbench 1, and then start the motor 3 inside the base 2. At this time, the motor 3 will drive the turntable 4 to rotate under the drive of electricity. The function of the support column 5 here is to ensure the stability of the turntable 4 during rotation. When the turntable 4 here rotates, it will drive the two rotating shafts 6 thereon to retract inward, and at the same time drive the rotating column 7 to rotate.

[0032] When the rotating column 7 rotates, it will drive the clamps 8 on both sides to clamp inward, so as to fix the plate. At the same time, the clamps here can be adjusted arbitrarily according to the width of the plate, which greatly improves the applicability of the device. The rubber pads 9 here are to further ensure the integrity of the plate and prevent the plate from being damaged due to excessive clamping force. The limit blocks 10 here slide inside the slide groove 11, further ensuring a translational movement of the clamps 8.

[0033] After the clamping is completed, the machine can be operated to punch the plate. After the punching is completed, the motor 15 in the column 14 at the front end of the top box 13 can be started. The bottom block 12 here provides a stable support for the top box 13. After the motor 15 is powered on, it will drive the bidirectional threaded rod 16 to rotate. At the same time, the two special-shaped blocks 17 on it will shrink inward synchronously, driving the long axis 18 on it to move inward and extend forward in an X shape. At this time, the top plate 19 will push out the punched plate, which greatly reduces the need for manual intervention and improves the speed of punching.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
