[0002] With the improvement of people's quality of life and the pursuit of outdoor leisure life, the outdoor furniture market is showing a booming development trend. The types of outdoor furniture are becoming increasingly diverse, covering multiple categories such as tables and chairs, parasols, flower stands and lounge chairs. They are widely used in family courtyards, parks and hotel outdoor leisure places, and their materials have gradually expanded from traditional wood and bamboo to metal, plastic and various composite materials.

[0003] Metal tubing is a common material in outdoor furniture manufacturing due to its high strength, durability, and versatility in design. For example, aluminum alloy and stainless steel tubing are widely used to build the frame structure of outdoor furniture. When processing outdoor furniture tubing, a stamping device is required to process it into parts with specific shapes and sizes.

[0004] Currently, the stamping equipment for outdoor furniture pipe fittings on the market first places the pipe fitting to be processed on the outside of the lower mold, and then uses a hydraulic rod to drive the upper mold base to move downward to perform the stamping work. However, since the size of the lower mold is fixed, when stamping pipe fittings of different sizes, the pipe fittings are prone to shaking, which will affect the subsequent processing quality and thus fail to meet the needs of users. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a stamping device for outdoor furniture pipe fittings, aiming to improve the problem that existing stamping devices for outdoor furniture pipe fittings are inconvenient for stamping pipe fittings of different sizes.

Springs are provided on the outside of the sliding rods. One end of each of the multiple springs is fixedly connected to one end of a corresponding hollow rod. The bottom ends of the two upper sliding rods are fixedly connected to the same connecting plate. Multiple stamping holes are equidistantly opened on one side of the connecting plate.

[0009] As a further description of the above technical solution:

[0010] The stamping mechanism also includes a hydraulic rod, which is fixedly connected to the top inner side of the L-shaped plate, and the output end of the hydraulic rod is fixedly connected to the top of the placement plate.

[0011] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when the movable rod is rotated, the driving bevel gear on its rear side will rotate accordingly, and the driven bevel gear meshing with it will also rotate, thereby driving the lead screw to rotate.

[0031] 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.

[0032] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a stamping device for outdoor furniture pipe fittings, including a base 1, a placement frame 3 fixedly connected to the top of the base 1, a hollow column 5 provided on the inner side of the base 1, a movable rod 6 rotatably connected to the front side of the hollow column 5, a driving bevel gear 7 fixedly connected to the rear end of the movable rod 6 through the hollow column 5, and a plurality of fixed plates 8 fixedly connected at equal intervals on the inner rear side of the hollow column 5, a lead screw 9 rotatably connected to one side of the fixed plate 8, a driven bevel gear 10 fixedly connected to one end of each of the multiple lead screws 9 through the corresponding fixed plate 8, and a driven bevel gear 10 fixedly connected to one end of each of the multiple driven bevel gears 10 meshing with the surrounding area of ​​the driving bevel gear 7, a movable column 11 on the outer side of the lead screw 9, an arc-shaped support plate 12 fixedly connected to one end of each of the multiple movable columns 11 through the corresponding hollow column 5, and an L-shaped plate 16 fixedly connected to the rear side of the base 1, a stamping mechanism 2 provided on the inner top of the L-shaped plate 16, the stamping mechanism 2 being used to facilitate the stamping of the clamped pipe fittings;

[0033] Specifically, the driving bevel gear 7 located behind the rotating movable rod 6 will rotate accordingly, and the driven bevel gear 10, which is tightly meshed with the driving bevel gear 7, will also start to rotate accordingly. This linkage mechanism allows the lead screw 9 connected to the driven bevel gear 10 to rotate. As the lead screw 9 rotates, the outer movable column 11 will move around the perimeter outside the limit rod 13, and the arc-shaped support plate 12 on the movable column 11 will also move accordingly. At this time, the size supported by the arc-shaped support plate 12 can be adjusted according to the actual size of the pipe fitting, thereby ensuring that the arc-shaped support plate 12 can adapt to pipe fittings of different sizes, thus ensuring the subsequent processing quality of the pipe fitting and meeting the needs of the user.

[0034] Reference Figure 1 , Figure 3 and Figure 5The stamping mechanism 2 includes a placement plate 202, which is located on the upper inner side of the L-shaped plate 16. Multiple stamping heads 203 are fixedly connected at equal intervals to the bottom of the placement plate 202. A base plate 204 is fixedly connected to both the left and right sides of the placement frame 3. Hollow rods 205 are fixedly connected to the top of the base plate 204 and the left and right sides of the bottom of the placement plate 202. Sliding rods 206 are slidably connected inside the hollow rods 205. Springs 207 are provided on the outer side of the sliding rods 206. One end of each spring 207 is fixedly connected to one end of a corresponding hollow rod 205. The bottom ends of the two upper sliding rods 206 are fixedly connected to the same... A connecting plate 208 has multiple punching holes 209 evenly spaced on one side. The punching mechanism 2 also includes a hydraulic rod 201, which is fixedly connected to the top of the inner side of the L-shaped plate 16. The output end of the hydraulic rod 201 is fixedly connected to the top of the placement plate 202. The size of the multiple sliding rods 206 is matched with the internal size of the corresponding hollow rods 205, which makes the sliding rods 206 move more smoothly. The internal size of the multiple punching holes 209 is larger than the size of the corresponding punching head 203, which makes it easier for the punching head 203 to pass through the punching holes 209.

[0035] Specifically, the hydraulic rod 201 enables the placement plate 202 to move precisely up and down in the vertical direction. When the placement plate 202 moves downward, it drives the connecting plate 208 to move downward, thereby squeezing the slide rod 206 located on the lower side. During this process, the spring 207 on the outside of the slide rod 206 will generate a corresponding pressure response due to the compression. At the same time, the connecting plate 208 moves upward while moving downward, thereby squeezing the upper spring 207. This bidirectional compression mechanism ensures that the punch head 203 can pass smoothly through the punch hole 209 and perform precise punching operation on the pipe located on the outside of the hollow column 5. In this way, it can be ensured that the pipe to be processed is subjected to uniform pressure in all positions, thereby significantly improving the practicality of the device.

[0036] Reference Figure 1 , Figure 2 and Figure 3 A control panel 15 is fixedly connected to the top right front end of the base 1. The control panel 15 is fixedly connected to the micro motor 4 and the hydraulic rod 201 respectively.

[0037] Specifically, the operation of the micro motor 4 and the hydraulic rod 201 can be controlled through the control panel 15. The micro motor 4 is model BMM-24, and the hydraulic rod 201 is model HSG.

[0038] Reference Figure 4 Multiple movable columns 11 are fixedly connected to both sides of sliders 14, and multiple fixed plates 8 are fixedly connected to one side of multiple limiting rods 13. Multiple sliders 14 are slidably connected to the outer side of the corresponding limiting rods 13 respectively.

[0039] Specifically, the movement trajectory of the movable column 11 can be limited by the limiting rod 13, allowing it to move more smoothly.

[0040] Reference Figure 2 A micro motor 4 is fixedly connected to the rear side of the placement frame 3. The output end of the micro motor 4 passes through the placement frame 3 and is fixedly connected to the rear end of the hollow column 5.

[0041] Specifically, the micro motor 4 can drive the hollow column 5 to rotate, which makes it convenient to perform comprehensive processing on the pipe fitting.

[0042] Working principle: When using this device, first observe the internal dimensions of the pipe to be processed, then place it on the outside of the hollow column 5. Then rotate the movable rod 6, and the driving bevel gear 7 on its rear side will rotate accordingly. The driven bevel gear 10 meshing with it will also rotate, thereby driving the lead screw 9 to rotate. At this time, the movable column 11 on the outside of the lead screw 9 will move around outside the limit rod 13. The arc-shaped support plate 12 on the movable column 11 will move accordingly. The size of the arc-shaped support plate 12 can be adjusted according to the actual internal dimensions of the pipe, so that it can adapt to pipes of different sizes. The pipe is not easy to shake during processing, thus ensuring the subsequent processing quality of the pipe and meeting the needs of users.

[0043] After the pipe is clamped, the hydraulic rod 201 can drive the placement plate 202 to move up and down in the vertical direction. When it moves downward, the connecting plate 208 will squeeze the lower slide rod 206. At this time, the spring 207 on the outside of the slide rod 206 will be squeezed. At the same time, the connecting plate 208 will move upward and squeeze the upper spring 207. At this time, the punch head 203 can pass through the punch hole 209 to perform a punching operation on the pipe located outside the hollow column 5, which can make the force on each position of the pipe to be processed more even, thereby improving the practicality of the device. The micro motor 4 can drive the hollow column 5 to rotate, which can facilitate the comprehensive processing of the pipe. After the punching work is completed, the spring 207 will release the squeezed force and drive the connecting plate 208 to spring back to its original shape.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
