Description

Technical Field

[0001] This utility model relates to the field of wind hood processing technology, specifically a high-precision wind hood arc bending extrusion mechanism. Background Technology

[0002] The exhaust hood measures resistance and exhaust volume to evaluate its economic efficiency in terms of power consumption, specifically whether a better capture and control effect can be achieved with a smaller exhaust volume and less energy loss. During the production of the exhaust hood, the rod body needs to be extruded into an arc shape.

[0003] Traditional extrusion mechanisms have certain shortcomings in use. They cannot extrude the rods into the same arc shape, resulting in different arc dimensions for each rod. This reduces the accuracy of the extrusion arc shape and limits the practicality of the extrusion device. Furthermore, they cannot adjust the arc angle of the rod extrusion according to the actual extrusion needs, which also reduces the application range of the extrusion device. Therefore, we propose a high-precision wind hood arc bending extrusion mechanism. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0024] A high-precision wind hood arc bending extrusion mechanism includes a base plate 1, a rectangular box 13 fixedly connected to the surface of the base plate 1, an insertion hole 15 opened in the rectangular box 13, a steel plate 21 slidably connected in the rectangular box 13, an insertion rod 14 inserted into the outside of the rectangular box 13, the insertion rod 14 passing through the insertion hole 15 and extending into the steel plate 21, a pressure sensor 18 fixedly connected to the top of the steel plate 21, a top plate 3 fixedly connected to the top of the base plate 1, a control plate 8 fixedly connected to the surface of the top plate 3, the pressure sensor 18 being electrically connected to the control plate 8, a sliding groove 4 opened in the top plate 3, a vertical plate 9 slidably connected in the sliding groove 4, a top groove 20 opened in the vertical plate 9, and a pressure plate 11 provided on the top of the vertical plate 9.

[0025] In this embodiment, as Figure 1 and Figure 2As shown, a connecting plate 19 is fixedly connected to the bottom of the pressure plate 11. The connecting plate 19 extends into the top groove 20 and is slidably connected to the top groove 20. A rod 10 abuts between the pressure plate 11 and the vertical plate 9. A fastening bolt 12 is threadedly connected to the side of the vertical plate 9. The side end of the fastening bolt 12 extends into the top groove 20 and abuts against the surface of the connecting plate 19. A drive motor 5 is installed on the side of the top plate 3. A threaded rod 6 is fixedly connected to the output end of the drive motor 5. A threaded sleeve 7 is threadedly connected to the outside of the threaded rod 6.

[0026] The electric telescopic rod 16 can drive the bending plate 17 to move downwards, bending the rod 10 and bringing the bottom of the rod 10 against the pressure sensor 18. Then, the electric telescopic rod 16 stops working under the action of the control plate 8, so that the extrusion arc angle of each rod 10 is the same, improving the extrusion forming rate and accuracy of the rod 10. At the same time, the position of the vertical plate 9 can be adjusted according to the actual length of the rod 10, so that the vertical plate 9 can limit and fix rods 10 of different sizes.

[0027] In this embodiment, as Figure 3 and Figure 4 As shown, the threads at both ends of the threaded rod 6 have opposite directions of rotation. The threaded sleeve 7 is fixedly connected to the vertical plate 9. An electric telescopic rod 16 is installed on the top of the top plate 3. A bending plate 17 is fixedly connected to the bottom of the electric telescopic rod 16. The bending plate 17 is set on the top of the rod body 10. The bending plate 17 is opposite to the pressure sensor 18. A caster 2 is set on the bottom of the bottom plate 1. The caster 2 is movably connected to the bottom plate 1. Multiple insertion holes 15 are provided. The multiple insertion holes 15 are evenly distributed in the rectangular box 13. The dimensions of the multiple insertion holes 15 are all the same.

[0028] The insertion rod 14 can be used to connect the insertion hole 15 and the steel plate 21, thereby adjusting the vertical position of the pressure sensor 18 and adjusting the bending angle of the rod 10, making the extrusion mechanism more widely applicable.

[0029] The working process of this utility model is as follows: When the high-precision wind hood arc bending extrusion mechanism designed in this scheme is working, the drive motor 5 drives the threaded rod 6 to rotate. Since the threaded rod 6 and the threaded sleeve 7 are threadedly connected, the vertical plate 9 can be driven to slide in the slide groove 4. The vertical plate 9 can be adjusted according to the length of the rod body 10. Then, the connecting plate 19 at the bottom of the pressure plate 11 is placed in the top groove 20, so that the pressure plate 11 and the vertical plate 9 abut against the surface of the rod body 10. The fastening bolt 12 is rotated to fix the connecting plate 19, thereby limiting the position of the rod body 10. Then, the switch of the electric telescopic rod 16 is turned on, and the electric telescopic rod... 16 drives the bending plate 17 to move downwards, which can bend the rod 10 so that the bottom of the bent rod 10 abuts against the pressure sensor 18. The signal can then be transmitted to the control board 8, which stops the electric telescopic rod 16. This improves the accuracy of bending each rod 10. When the bending angle needs to be adjusted, the steel plate 21 is moved within the rectangular box 13, and then the insert rod 14 is inserted into the insertion hole 15 and the steel plate 21. This allows the position of the steel plate 21 and the pressure sensor 18 to be adjusted, thereby adjusting the bending angle of the rod 10 and improving the practicality and application range of the extrusion mechanism.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
