Description

Technical Field

[0001] This utility model relates to the field of sheet metal bending technology, and in particular to a bending device for a dryer duct plate. Background Technology

[0002] Dryer duct plate bending equipment plays a crucial role in the bending process of dryer duct plates. It is used to bend the duct plates of the dryer, completing the production of the dryer duct, so as to facilitate the bending of the dryer duct plates and the subsequent assembly and use of the dryer duct plates. Dryer duct plate bending equipment is mostly used in the duct component processing lines of household dryer manufacturers to bend cold-rolled steel plates and galvanized steel plate blanks into specific air guiding structures, as well as in industrial dryer manufacturers to process multi-angle bending and forming of thick-walled duct plates.

[0003] When bending the duct plates of a dryer to facilitate subsequent assembly and use, and to complete the production of the dryer's air ducts, duct plate bending equipment is required. Existing duct plate bending equipment often employs continuous and intermittent operation, combining physical stamping and mechanical friction to achieve bending. Most are semi-automatic models equipped with basic feeding and positioning structures, requiring manual assistance for loading / unloading and some parameter adjustments. This processing method has significant limitations: manual positioning accuracy is easily affected by operator experience; multiple bending processes require repeated manual adjustments to the plate position, extending the processing time per piece; and it can easily lead to accumulated errors, causing sealing problems during duct plate assembly and reducing the overall performance stability of the dryer. This results in a significant increase in production costs, reduced product quality, and shortened service life. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a drying machine air duct plate bending device, which aims to improve the problem of repeatedly manually adjusting the position of the plate in the prior art.

[0018] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 An embodiment of this utility model provides a drying machine duct plate bending device, including a shell 1, on which support plates 3 are fixedly connected to the left and right sides. A slide rail 4 is provided on the inner wall of the support plate 3. A sliding disk 5 is slidably connected to the inner wall of the slide rail 4. A support column 6 is rotatably connected to the outer wall of the sliding disk 5. A rotating disk 7 is rotatably connected to the outer wall of the support column 6. A sliding groove 8 is provided on the inner wall of the rotating disk 7. A connecting rod 9 is slidably connected to the inner wall of the sliding groove 8. A gripper 10 is fixedly connected to the right end of the connecting rod 9. A roller 11 is rotatably connected to the inner wall of the gripper 10. A replacement mechanism 2 is fixedly connected to the top of the shell 1. The replacement mechanism 2 is used for quick disassembly and installation of replacement templates. Specifically, the outer shell 1 serves as the basic frame, with the support plates 3 fixed on its left and right sides providing stable support for the moving parts. The slide rail 4 on the inner wall of the support plate 3 guides the sliding disk 5 to move precisely along a straight line, adjusting the lateral position of the bending station. In conjunction with the rotation function of the support column 6, the bending angle range of the sheet metal can be flexibly adjusted. The slide groove 8 on the inner wall of the rotating disk 7 slides in conjunction with the connecting rod 9, driving the gripper 10 to achieve opening and closing action. The roller 11 on the inner wall of the gripper 10 reduces friction with the sheet metal during clamping, avoiding surface scratches, and ensuring that the sheet metal does not shift during bending. The replacement mechanism 2 at the top is a core innovative component. Through the quick-release structure, it enables the rapid disassembly and installation of the template, adapting to the bending requirements of different specifications of air duct plates, greatly improving the processing efficiency and adaptability of the equipment.

[0019] Please see the appendix Figure 2 and attached Figure 4 The replacement mechanism 2 includes a base 201, the bottom of which is fixedly connected to the top of the outer shell 1. A rotating column 202 is rotatably connected to the inner wall of the base 201. A protective shell 203 is fixedly connected to the front end of the rotating column 202. A handle 204 is fixedly connected to the outer wall of the protective shell 203. A first spring 205 is fixedly connected to the inner wall of the protective shell 203. A lock head 206 is fixedly connected to the rear end of the rotating column 202. A mold 207 is slidably connected to the outer wall of the protective shell 203. A locking groove 208 is opened on the inner wall of the mold 207. Specifically, the replacement mechanism 2 enables the rapid replacement of mold 207 through the coordinated operation of various components. The base 201 provides fixed support for the overall structure, and the rotating column 202 can rotate flexibly around the base 201. Rotating the handle 204 drives the protective shell 203 and the rotating column 202 to rotate, so that the rear locking head 206 is aligned with the locking groove 208 of the mold 207. The first spring 205 inside the protective shell 203 provides elasticity, holds the components, and provides a certain clamping force to help stabilize the mold 207. When disassembling, rotating the handle 204 in the opposite direction causes the locking head 206 to disengage from the locking groove 208, and the mold 207 can easily slide out along the outer wall of the protective shell 203. This structure makes the replacement of mold 207 convenient, and the spring elasticity lock ensures that the mold 207 is installed accurately and stably.

[0020] Please see the appendix Figure 1 Appendix Figure 5 and attached Figure 6 A sliding rod 12 is fixedly connected to the front side of the outer shell 1.

This structure combines the sliding of the sliding block 15 with the positioning of the through holes, which can flexibly adjust the processing positioning reference and adapt to the bending requirements of different specifications of air duct plates.

[0021] Please see the appendix Figure 3 Appendix Figure 5 and attached Figure 6 The inner wall of the adjusting block 16 is slidably connected to a support rod 18, the top of the support rod 18 is fixedly connected to a support platform 19, the outer wall of the rotating disk 7 is fixedly connected to a fixing block 22, the inner wall of the fixing block 22 is rotatably connected to a pin 23, the inner wall of the support rod 18 is fixedly connected to a second spring 20, and the inner wall of the support rod 18 is slidably connected to a locking tongue 21. Specifically, the support rod 18 sliding on the inner wall of the adjusting block 16 can be adjusted up and down. The top support platform 19 provides stable support for the plate. The second spring 20 inside the support rod 18 pushes the locking tongue 21 out and inserts it into 17 to adjust the height. The fixing block 22, together with the pin 23, locks the clamp 10 to prevent loosening and causing the plate to fall off.

[0022] Working principle: The support plates 3, which are fixedly connected to the left and right sides of the outer shell 1, provide a platform for the operation of subsequent components. The slide rails 4 on the inner wall of the slide plate 5 provide guidance for the sliding of the slide plate 5, which can move vertically. The rotation of the rotating plate 7 is supported by the rotating support column 6 on the outer wall of the slide plate 5. When the rotating plate 7 is rotating, the connecting rod 9 is affected by the slide groove 8 and retracts inward along the oblique angle with the fixed gripper 10 to clamp the plate to be bent. At the same time, the roller 11 on the inner wall of the gripper 10 can provide a certain lateral sliding for the plate. With the help of the rotating support column 6, the clamping of the plate reduces the manual support and alignment work. It can also be combined in a movable manner, so that a single person can control the bending task of a long plate, which increases the positioning accuracy and saves manpower. The replacement mechanism 2 is fixedly connected to the top of the outer shell 1. The replacement mechanism 2 is used for quick disassembly and installation of the replacement mold 207 to adapt to the needs of plates with different bending degrees. The replacement mechanism 2 includes a base 201, which serves as the foundation of the mechanism and provides working space for subsequent components. A rotating column 202 on its inner wall connects the base 201 and the locking groove 208. A protective shell 203 fixed to the front end of the rotating column 202 provides an installation platform for the handle 204 fixed to the outer wall, which facilitates the control of the rotation of the rotating column 202. A first spring 205 fixed to the inner wall of the protective shell 203 provides a certain rebound force to pop out and unlock the replacement mechanism 2 for easy handling and replacement. A lock head 206 fixed to the rear end of the rotating column 202 is inserted into the locking groove 208 opened in the inner wall of the mold 207. After rotation, it can be locked in quickly to prevent the replacement mold 207 from loosening and falling off.
