[0019] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0020] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0021] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0022] Combination Figure 1-3As shown, the metal U-shaped tube processing and feeding device includes a machine base 1. The machine base 1 is equipped with a slide 2 and a sliding cylinder 3 for driving the slide 2 to move left and right. The slide 2 is equipped with a pair of left and right support seats, wherein the left support seat is marked 41 and the right support seat is marked 42. A pair of sliding grooves are opened in the support seats, and a sliding rod 6 is provided in the sliding groove. A pressure seat 7 is provided at the top of the pair of sliding rods 6, and the pressure seat 7 rests on the support seats. A retaining ring 7 is provided at the bottom of the sliding rod 6, and a spring 8 is provided on the sliding rod 6 between the retaining ring 7 and the support seat. The pressure seat 7 and the support seats are respectively opened with opposite upper and lower placement grooves 9. The placement grooves 9 are U-shaped structures. A through push groove 10 is opened on the support seat directly opposite the lower placement groove. The machine base 1 has a middle opening 11, and a pair of left and right push components are provided in the middle opening 11. The push components are used to push the pressure seat 7, and an opening and closing component is provided between the push components.

[0023] In this embodiment, the opening and closing assembly is set to correspond to the feeding station, and the two left and right pushing assemblies are set to correspond to the processing station. A feeding vibratory feeder is also provided on the machine platform, and a feeding rack is provided at the outlet of the feeding vibratory feeder. A pushing assembly is provided at the bottom of the feeding rack, and the pushing assembly and the opening and closing assembly are arranged in front of and behind each other.

[0024] As shown in the figure, in the initial state, the left support base faces the opening and closing assembly. First, the opening and closing assembly pushes the sliding rod inside the left support base upward, causing the sliding rod to open the pressure seat on it. The spring is further compressed, and the pressure seat moves away from the left support base, forming a feeding port. Then, the pushing assembly pushes the U-shaped tube at the bottom of the feeding frame into this feeding port. The U-shaped tube is positioned in the placement slot on the left support base, thus feeding the U-shaped tube. The opening and closing assembly resets, and under the restoring force of the spring, the pressure seat resets, fixing the tube.

[0025] The sliding cylinder drives the slide block to move to the left to the left push assembly, awaiting processing. At the same time, the right support seat moves to the loading position, waiting to load the next U-shaped pipe fitting onto the right support seat. After the previous U-shaped pipe fitting is processed, the push assembly on the same side is used to push open the left pressure seat, and at the same time, push the U-shaped pipe fitting out of the placement slot on the left support seat.

[0026] As a preferred structure, such as Figure 4-5 The push assembly includes a push cylinder 12 and a support block 13 fixedly installed on the machine base 1. The drive shaft of the push cylinder 12 is provided with a push plate 14. The push plate 14 has a slot 15, and the support block 13 is located in the slot 15. The front side of the push plate 14 is provided with a guide frame 16, and the rear side is provided with a rising push block 17 that matches the push slot. The machine base 1 is provided with a dropping frame 18 directly opposite the guide frame.

[0027] In the diagram, the guide frame and the unloading frame are staggered, with the bottom of the guide frame located below the top of the unloading frame. After the previous U-shaped tube is processed, the left pressure seat is pushed away from the left support seat by the push assembly on the same side. Specifically: First, the push cylinder drives the push plate to move upward, which in turn moves the guide frame and the rising push block on it upward, while also pushing the sliding rod on the left pressure seat upward. As the push plate moves upward, the left pressure seat moves away from the left support seat under the push of the sliding rod, and the rising push block continues to move upward through the push groove, pushing the U-shaped tube on the left support seat to the guide frame. At the same time, the top of the unloading frame aligns with the bottom of the guide frame, and the U-shaped tube is unloaded through the unloading frame.

[0028] As the left pressure seat moves away from the left support seat, the spring is further compressed. After the U-shaped tube is unloaded, the push cylinder resets, and the support block and guide frame also reset. Simultaneously, under the action of the spring, the pressure seat falls back onto the support seat.

[0029] In practice, when the previous U-shaped fitting is being processed, a U-shaped fitting is already loaded onto the right support seat at the loading position, and the U-shaped fitting is fixed by the right pressure seat. After the previous U-shaped fitting is unloaded, the sliding mechanism moves one station to the right, the right support seat moves to the corresponding processing position, and the left support seat moves to the loading position.

[0030] In this structure, such as Figure 5 The support block 13 has a guide groove 19 on its back, and the rising push block 17 is located in the guide groove 19. The guide groove mainly serves to guide and limit the rising push block, ensuring that the rising push block pushes the U-shaped tube out of the support seat and ensuring the stability of the pushing action.

[0031] In this device, a stand 20 is mounted on the frame 1. A pressing cylinder 21 is mounted on the top of the stand 20, facing downwards, corresponding to the support block. A pressing head 22 is mounted on the drive shaft of the pressing cylinder 21. When the support seat moves to the processing position, the pressing seat, under the action of a spring, presses down on the U-shaped tube. Simultaneously, the pressing seat is directly below the pressing cylinder on the same side. To further ensure processing stability, the pressing cylinder drives the pressing head to press against the pressing seat below it, further compressing the U-shaped tube.

[0032] In addition, such as Figure 4 In this assembly, the opening and closing component includes an opening and closing cylinder 23, and the drive shaft of the opening and closing cylinder 23 is equipped with an opening and closing base plate 24. When the support seat is in the feeding position, the opening and closing component lifts the pressure seat on it, causing the pressure seat to move away from the support seat and form a feeding port. Specifically: the opening and closing cylinder drives the opening and closing base plate to move upward, the opening and closing base plate pushes the slide rod inside the support seat upward, the slide rod lifts the pressure seat, the spring is further compressed, and the pressure seat moves away from the support seat to form a feeding port, waiting for feeding.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
