[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 1 and Figure 2 As shown in FIGS. and, the full-automatic automotive sun visor shaft pipe bending machine includes a workbench 1. A loading box 2 is arranged on the front panel of the workbench 1. A material ejection mechanism 3 is arranged below the loading box 2 for ejecting the materials in the loading box 2 upward out of the loading box 2. A discharging mechanism 4 extends rearward from the upper end surface of the loading box 2 towards the workbench 1. A pushing mechanism 5 is synchronously arranged below the discharging mechanism 4. The pushing mechanism 5 is used to push the materials on the discharging mechanism 4 and drop them onto the material receiving mechanism 6 arranged below the end of the discharging mechanism 4. A feeding mechanism 7 is arranged on the left side of the material receiving mechanism 6, and a pipe bending mechanism 8 is arranged on the right side of the material receiving mechanism 6. The feeding mechanism 7 is used to send the materials on the material receiving mechanism 6 to the pipe bending mechanism 8 for pipe bending operation.

[0033] Specifically, refer to Figures 3 to 5 As shown in the figure, the aforementioned loading box 2 includes a bottom plate 201, a front plate 202 oppositely arranged with the front panel of the aforementioned workbench 1, and two end plates 203 on both sides. In the embodiment of the present utility model, the aforementioned bottom plate 201 is set to be in a downward inclined state, so that the materials entering the loading box 2 can freely fall to the downward inclined end of the bottom plate 201. And since a material ejection port 204 is opened at the downward inclined end of the bottom plate 201, the material ejection mechanism 3 arranged below the material ejection port 204 can eject the materials at the end of the bottom plate 201 out of the loading box 2 through the material ejection port 204.

[0034] In addition, in the present utility model, a feeding box adjusting plate 205 with the same size as the aforementioned end plate 203 is embedded inside the feeding box 2, and a feeding box adjusting shaft 206 is sleeved through holes along the length direction of the aforementioned bottom plate 201 on the feeding box adjusting plate 205. Thus, the feeding box adjusting plate 205 can move back and forth on the feeding box adjusting shaft 206, thereby controlling the length or size of the material fed into the feeding box 2, being able to adapt to the feeding of materials of different sizes, and having strong adaptability.

[0035] Referring to Figure 3 , for the ejector mechanism 3, it includes an ejector member 301, an ejector cylinder 302 and a linear guide rail 303. The ejector cylinder 302 is arranged below the ejector member 301, and one end of the ejector cylinder 302 is fixedly connected to the aforementioned linear guide rail 303 through a slider 304. Thus, by the ejector cylinder 302 sliding up and down on the linear guide rail 303, the ejector member 301 can be pushed to move up and down synchronously, and then through the aforementioned ejection port 204, the material can be ejected from the feeding box 2.

[0036] When the material is ejected from the aforementioned feeding box 2, it will move towards the discharging mechanism 4 extending rearward from the upper end face of the feeding box 2 towards the workbench 1. Referring to Figure 6 and Figure 7 , the aforementioned discharging mechanism 4 includes a first discharging plate 401 and a second discharging plate 402 that are inclined downward. The second discharging plate 402 is placed on the upper end face of the aforementioned first discharging plate 401. Since both discharging plates are arranged in a downward inclined state, the material can automatically move towards the end of the discharging plate without any external driving force. Since the second discharging plate 402 is placed on the upper end face of the aforementioned first discharging plate 401, there is a lap joint between the two discharging plates. In the embodiment of the present utility model, a plurality of pushing grooves 403 are opened at the above-mentioned lap joint. A pushing mechanism 5 is arranged below the pushing grooves 403, and the pushing mechanism is used to push the material freely moving to the above-mentioned lap joint out of the lap joint and continue to move towards the end of the aforementioned second discharging plate 402. The setting of the lap joint can, on the one hand, prevent the material from accumulating on the discharging mechanism 4, and on the other hand, can discharge and push the material sequentially and orderly, saving the process time and improving the operation efficiency.

[0037] Referring to Figure 6 and Figure 7, specifically for the above-mentioned pusher mechanism 5, it includes a pusher cylinder 501, a pusher pin shaft bracket 502 disposed above the pusher cylinder 501 and fixedly connected to the pusher cylinder 501, and a pusher cylinder fixed seat 503 disposed below the pusher cylinder 501 and fixedly connected to the aforementioned workbench 1. The pusher cylinder fixed seat 503 is fixedly connected to the aforementioned workbench 1, which can avoid the situation of material jamming caused by pusher misalignment during the pusher process. And a plurality of pin shafts holes 505 for accommodating pusher pin shafts 504 are provided on the aforementioned pusher pin shaft bracket 502. The number of the above-mentioned pin shafts holes 505 is not only equal to that of the aforementioned pusher grooves 403, but also the hole positions correspond one by one to the groove positions of the aforementioned pusher grooves 403. Of course, the number of the aforementioned pin shafts holes 505 and the number of pusher grooves 403 can be selected according to actual needs, and can be 4, 6, 8, 10, etc. During actual operation, when the pusher cylinder 501 is started, synchronously, the pusher cylinder 501 will drive the pusher pin shaft bracket 502 to move up and down, and then drive the pusher pin shafts 504 located on the pusher pin shaft bracket 502 to move up and down. When the pusher pin shafts 504 cross over the aforementioned pusher grooves 403, the materials staying on the lap joint of the aforementioned discharge plate can be pushed out and move to the next process.

[0038] When the material is pushed out from the lap joint of the discharge plate, it will freely move forward to the end of the aforementioned second discharge plate 402. A receiving mechanism 6 is provided below the end of the second discharge plate 402. Refer to Figure 7 , the receiving mechanism 6 includes a receiving groove 601 and a receiving groove base 602 disposed below the receiving groove 601 and fixedly connected to the workbench 1. The material will automatically fall onto the receiving groove 601, and the inner diameter of the receiving groove 601 is slightly larger than the outer diameter of the material, which can make the material fall steadily into the receiving groove 601 and will not fall to a position outside the receiving groove 601.

[0039] In the present utility model, a feeding mechanism 7 is provided on the left side of the above-mentioned receiving mechanism 6. The feeding mechanism 7 is used to feed the material falling into the receiving groove 601 into a bent pipe mechanism 8 disposed on the right side of the receiving mechanism 6.

[0040] Specifically, refer to Figure 8 , the feeding mechanism includes a lead screw 701, a servo motor 702 for driving the lead screw 701 to rotate, a lead screw slider 703 sleeved and threadedly connected to the lead screw 701, guide rails 704 distributed on both sides of the lead screw slider 703, and a feeding member 705 disposed on the guide rails 704 and connected to the lead screw slider 703. During actual operation, when the servo motor 702 is started, it drives the lead screw 701 to rotate, and then the lead screw drives the lead screw slider 703 to rotate. The lead screw slider 703 can drive the feeding member 705 to perform a linear motion on the guide rails 704. When the feeding member 705 approaches the receiving groove 601, the material in the receiving groove 601 can be pushed out of the receiving groove 601 and move towards the bent pipe mechanism 8 on the right side of the receiving groove 601.

[0041] Refer to Figure 9 and 10 For the elbow bending mechanism 8, it includes a clamping block 801 and a steering member 802 rotatably connected to the clamping block. An arc-shaped groove 803 is formed in the steering member 802. When the material is pushed by the feeding member 705 to the clamping block 801 and continues to move towards the steering member 802, while the steering member 802 drives the material to rotate, and in cooperation with the arc-shaped groove 803 formed in the steering member 802, the material can be pressed into the required elbow state.

[0042] In addition, in the present utility model, a positioning block is further provided in front of the steering member 802 facing the workbench 1 for positioning the material during the elbow bending process to prevent elbow bending deviation.

[0043] The above embodiments are only used to illustrate the technical concept and characteristics of the present utility model, and their purpose is to enable those skilled in the art to understand the content of the present utility model and implement it accordingly. It should not be used to limit the protection scope of the present utility model.
