Description

Technical Field

[0001] The invention relates to the technical field of material guide structures, in particular to a material guide structure for pre-treating round pipes used for processing stainless steel products. Background Art

[0002] In smart manufacturing, stainless steel sinks are a common stainless steel product that uses round pipe pretreatment. In production, round stainless steel pipes need to be pretreated, such as cutting, punching, bending and grinding, and then assembled into sinks.

[0003] When punching holes in a round tube, manual loading is required, and then the round tube is transported to the designated punching position through a material guide structure. In addition, the punching process requires fixing and unloading, which is labor-intensive, increases labor costs, and is cumbersome and time-consuming. Therefore, those skilled in the art provide a material guide structure for pre-processing round tubes for stainless steel product processing to solve the problems raised in the above background technology. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the background technology and to provide a material guiding structure for pre-processing round pipes used for processing stainless steel products.

[0006] Preferably, a feeding port corresponding to the slot is provided at the lower end of the trough, and a connecting rod is provided between the rotating rings. The round tubes pre-stored in the trough are discharged through the feeding port.

[0007] Preferably, a discharge port is provided at one side of the lower end of the clamp ring, through which the round pipe after opening processing is discharged.

[0008] Preferably, symmetrically distributed clamping rods are provided between the clamping ring and the ring seat. The clamping rods fix the clamping ring on one side of the ring seat, thereby fixing the clamping ring, and the clamping ring limits the circular pipe during transportation.

[0009] Preferably, a sliding sleeve is embedded and installed inside the clamping ring, a positioning rod is slidably inserted inside the sliding sleeve, a clamping block is provided at one end of the positioning rod, a limiting ring is sleeved on the outer wall of the positioning rod, and a spring sleeved on the outer side of the positioning rod and connected to the clamping ring at one end is provided at one end of the limiting ring. The guide rod is slidably supported inside the clamping rod through the sliding sleeve, and the elastic force of the spring acts on the positioning rod through the limiting ring, so that the clamping rod is elastically supported.

[0010] Preferably, the outer wall of the rotating ring is rotatably mounted with balls distributed in an annular array, the inner wall of the ring seat is provided with an annular ring track, and the balls are rotatably mounted inside the ring track. When the rotating ring rotates, the balls roll inside the guide rail to support the rotating ring during the rotation process, thereby improving the smoothness of the rotating ring during the rotation process.

[0011] Preferably, the upper end of the base is provided with guide rollers which are located below the ring seat and are equidistantly distributed. The guide rollers support the round tubes being cut, and then the round tubes are transported by adjusting the rotation of the guide rollers.

[0012] Preferably, the upper end of the base is provided with a symmetrically distributed bearing bracket, one end of the bearing bracket is provided with a motor 1, one end of the motor 1 is provided with a screw rotatably mounted inside the bearing bracket, and a nut is threadedly mounted on the outer wall of the screw. The bearing bracket rotatably supports the screw.

[0013] Preferably, a slider is provided at one end of the nut, a guide rail slidably mounted with the slider is provided between the bearing brackets, and a mounting block connected to the hydraulic rod is provided at one end of the nut. The nut slides on the outer wall of the guide rail through the slider to guide the nut to slide, and when the nut moves, the hydraulic rod is driven to move through the mounting block.

[0014] Preferably, the method steps for pretreatment of round tubes are as follows:

[0015] S1: Use a laser cutting machine or a CNC cutting machine to accurately cut the stainless steel round tube, cut the length of the stainless steel tube according to the design requirements, and feed the stainless steel tube into the trough. Multiple round tubes are pre-stored inside the trough at the same time. The round tube at the bottom of the trough is supported by the outer wall of the rotating ring. When the slot corresponds to the feeding port of the trough, the round tube at the bottom of the trough enters the slot. When the rotating ring rotates, it drives the round tube inside the slot to rotate. When the rotating ring rotates, it drives the round tube to rotate. At the same time, the round tube is limited by the clamping ring, which avoids the round tube from detaching during the transportation process, so that the round tube is effectively guided;

[0016] S2: After the round tube is transferred 90 degrees, the motor 1 drives the screw to rotate. Because the nut is guided by the slider on the outer wall of the guide rail, the nut drives the mounting block to move horizontally, and then drives the hydraulic rod to move horizontally, corresponding to the position where the round tube needs to be opened. At this time, the hydraulic rod drives the motor 3 to move toward the round tube, and the motor 3 drives the cutting head to rotate to open a hole in the round tube for the hole opening processing of the round tube. After the processing, the motor 3 is away from the round tube through the hydraulic rod to ensure that the subsequent rotating ring drives the rotation of the round tube;

[0017] S3: When the round tube rotates downward, the round tube ends being limited by the clamping ring, and the round tube is discharged through the discharge port and received by the guide roller to convey the round tube after the hole is opened. When the round tube is opened, the clamping groove pushes the round tube to move and squeezes the clamping block. The clamping block exerts an extrusion force on the spring, and the spring is pulled and extended. When the clamping block fits the outer wall of the round tube, the round tube is clamped, so that the round tube is positioned when the hole is opened. In the process of guiding and transporting the round tube, the clamping groove corresponds to the material trough again, and the material trough intermittently feeds the clamping groove, thereby realizing continuous feeding of the round tube and reducing manual participation.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention places the round tube in the clamping groove inside the rotating ring, and when the rotating ring rotates, it drives the round tube to be automatically transported. When the round tube is transported to the corresponding cutting head, the round tube is drilled. After the drilling of the round tube, the rotating ring rotates, driving the round tube to rotate, so as to realize automatic unloading of the round tube, and at the same time, the round tube is pre-stored through the material trough. When the rotating ring rotates to drive the clamping groove to correspond to the material trough, the automatic transportation of the round tube is realized, thereby reducing human participation and reducing labor costs. In the process of stainless steel water tank processing, the round tube is conveniently pre-processed and punched through the pre-storage material guiding structure.

When the rotating ring 4 rotates, because the circular tubes are distributed in a circle and the circular tubes pass through the circular outer wall of the rotating ring 4, when the rotating ring 4 rotates, the circular tubes themselves are rotated by the friction force, but the circular tubes are guaranteed to be stable in the material trough 7. When the rotating ring 4 rotates, it will drive the card slot 20 to rotate. After the card slot 20 corresponds to the material trough 7, the circular tube enters the card slot 20 through the loading port 16.

When the rotating ring 4 rotates, because the circular tubes are distributed in a circle and the circular tubes pass through the circular outer wall of the rotating ring 4, when the rotating ring 4 rotates, the circular tubes themselves are rotated by the friction force, but the circular tubes are guaranteed to be stable in the material trough 7. When the rotating ring 4 rotates, it will drive the card slot 20 to rotate.

[0056] When the circular tube is conveyed and the hole opening structure is corresponding, the block 34 will be pressurized first. Because the block 34 is elastically supported, when the circular tube fits the outer wall of the block 34, the elastic force of the spring 32 acts on the circular tube to position the circular tube during the hole opening process, thereby ensuring the stability of the circular tube during the hole opening.

[0060] Embodiment 4:

[0061] The steps for pretreatment of round pipes are as follows:

[0062] S1: Use a laser cutting machine or a CNC cutting machine to accurately cut the stainless steel round tube, cut the length of the stainless steel tube according to the design requirements, and feed the stainless steel tube into the material trough 7. A plurality of round tubes are pre-stored inside the material trough 7 at the same time. The round tube at the bottom of the material trough 7 is supported by the outer wall of the rotating ring 4. When the slot 20 corresponds to the feeding port 16 of the material trough 7, the round tube at the bottom of the material trough 7 enters the slot 20. When the rotating ring 4 rotates, it drives the round tube inside the slot 20 to rotate. When the rotating ring 4 rotates, it drives the round tube to rotate. At the same time, the round tube is limited by the clamping ring 17, which avoids the round tube from detaching during the transportation process, so that the round tube is effectively guided;

[0063] S2: After the round tube is transferred 90 degrees, the motor 13 drives the screw 10 to rotate. Because the nut 24 is guided by the slide block 23 on the outer wall of the guide rail 11, the nut 24 drives the mounting block 25 to move horizontally, and then drives the hydraulic rod 26 to move horizontally, corresponding to the position where the round tube needs to be opened. At this time, the hydraulic rod 26 drives the motor 3 27 to move toward the round tube, and drives the cutting head 28 to rotate through the motor 3 27 to open a hole in the round tube for the hole opening processing of the round tube. After the processing, the motor 3 27 is away from the round tube through the hydraulic rod 26 to ensure that the subsequent rotating ring 4 drives the rotation of the round tube;

[0064] S3: When the round tube rotates downward, the round tube ends being limited by the clamping ring 17, and the round tube is output through the discharge port 18 and received by the guide roller 2 to convey the round tube after the hole is opened. When the round tube is opened, the clamping groove 20 pushes the round tube to move and squeezes the clamping block 34. The clamping block 34 exerts an extrusion force on the spring 32, and the spring 32 is pulled and extended. When the clamping block 34 fits against the outer wall of the round tube, the round tube is clamped, so that the round tube is positioned when the hole is opened. In the process of guiding and transporting the round tube, the clamping groove 20 corresponds to the material groove 7 again, and the material groove 7 realizes intermittent feeding of the clamping groove 20, thereby realizing continuous feeding of the round tube and reducing manual participation.

At the same time, the round tube is limited by the clamping ring (17), so as to avoid the round tube from being separated during the transportation process, so that the round tube is effectively guided. S2: After the round tube is transferred 90 degrees, the motor 1 (3) drives the screw (10) to rotate. Since the nut (24) is guided by the slide block (23) on the outer wall of the guide rail (11), the nut (24) drives the mounting block (25) to move laterally, thereby driving the hydraulic rod (26) to move laterally to the position where the round tube needs to be drilled. At this time, the hydraulic rod (26) drives the motor 3 (27) to move toward the round tube, and drives the cutting head (28) to rotate through the motor 3 (27) to drill a hole in the round tube for drilling processing of the round tube. After the processing, the motor 3 (27) is away from the round tube through the hydraulic rod (26) to ensure that the subsequent rotating ring (4) drives the rotation of the round tube; S3: When the round tube rotates downward, the round tube stops being limited by the clamping ring (17), and the round tube is discharged through the discharge port (18) and received by the guide roller (2), so that the round tube after the hole is opened is transported. When the round tube is opened, the clamping groove (20) pushes the round tube to move and squeezes the clamping block (34). The clamping block (34) is forced to apply a squeezing force to the spring (32), and the spring (32) is pulled and extended. When the clamping block (34) fits on the outer wall of the round tube, the round tube is clamped, so that the round tube is positioned when the hole is opened. In the process of guiding and transporting the round tube, the clamping groove (20) corresponds to the material trough (7) again, and the material trough (7) intermittently feeds the clamping groove (20), thereby realizing continuous feeding of the round tube and reducing manual participation.
