Description

Technical Field

[0001] The utility model relates to a punching device, in particular to a chair frame punching device for producing folding chairs. Background Art

[0002] In the production process of folding chairs, punching holes in the chair frame is an essential process. However, after the existing punching machine completes the punching operation, the chair frame often slides down naturally without any special collection mechanism to assist. This situation leads to an obvious problem: during the sliding process, the chair frame is easy to rub against hard objects or rough surfaces outside, leaving scratches on the surface of the chair frame.

[0003] These scratches not only affect the aesthetics of the folding chair and reduce the overall quality of the product, but may also become more severe in long-term use, and even affect the function and safety of the chair. In addition, since the chair frame is made of metal, the appearance of scratches may also cause rust and other problems, further shortening the service life of the folding chair.

[0004] The utility model provides a punching device for automatically collecting chair frames. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a chair frame punching device for producing folding chairs which is provided with a collecting mechanism.

[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0022] This embodiment mainly describes the structure of the punching device, which is as follows:

[0023] A chair frame punching device for producing folding chairs, such as Figure 1-Figure 3 As shown, it includes a punching machine 1, and also includes a guide plate 2, a rotating shaft 3, a baffle 4, a first servo motor 5 and a support frame 6. The guide plate 2 is fixedly connected to the discharge end of the punching machine 1, the rotating shaft 3 is rotatably connected in the guide plate 2, and the rotating shaft 3 is radially provided with a baffle 4. The first servo motor 5 fixedly connected to the side of the guide plate 2 supplies energy to the rotating shaft 3. The support frame 6 is fixedly connected to the lower part of the punching machine 1. The receiving frame 8 is connected in the support frame 6, specifically located below the guide plate 2. The receiving frame 8 is U-shaped, and the middle part of the receiving frame 8 is horizontal for placing the chair frame. A buffer pad is provided in the middle part of the receiving frame 8. In this embodiment, the buffer pad is a foam pad 13 made of soft material. The first servo motor 5 drives the rotating shaft 3 to rotate at a uniform speed, the baffle 4 receives the chair frames one by one, and the rear baffle 4 guides the chair frames into the receiving frame 8.

[0024] like Figure 1 and Figure 3 As shown, it also includes a limit rod 7, a second servo motor 9 and a screw 10. The limit rod 7 is fixedly connected to the support frame 6. The receiving frame 8 is slidably connected to the limit rod 7. The second servo motor 9 is fixed to the support frame 6 and the output end is connected to the screw 10. The screw 10 is provided with a closed reciprocating thread. The screw 10 is connected to the receiving frame 8 through a thread. Turning on the second servo motor 9 can drive the screw 10 to rotate, and the screw 10 drives the receiving frame 8 to reciprocate horizontally, so that the chair frame exported by the guide plate 2 can be received.

[0025] like Figure 3As shown, a linear sensor 11 is also included. The linear sensor 11 is arranged on the receiving frame 8. The linear sensor 11 is electrically connected to the second servo motor 9. The function of the linear sensor 11 is to convert the linear mechanical displacement into an electrical signal. Therefore, the linear sensor 11 is placed at the front end of the receiving frame 8. When the chair frame falls from the guide plate 2, the linear sensor 11 is triggered. The linear sensor 11 drives the second servo motor 9 to run with the electrical signal. The second servo motor 9 drives the screw rod 10 to rotate, thereby moving the receiving frame 8 forward a certain distance. Since the screw rod 10 is provided with a closed reciprocating thread, the effect in actual production is that the chair frame continues to fall into the horizontally reciprocating receiving frame 8, ensuring the neat stacking of the chair frames, and the subsequent staff can take out the stacked and leveled chair frames as a whole.

[0026] like Figure 1 As shown, a placement box 12 is also included. The placement box 12 is fixed on the support frame 6. The placement box 12 is used to centrally place working tools such as screwdrivers.

[0027] like Figure 1 As shown, it also includes an adjusting foot 14, which is arranged at the bottom of the punching machine 1. By adjusting the adjusting foot 14, the punching machine 1 can be leveled to make punching smooth.
