[0031] Reference Figures 1 to 9A processing device for producing set screw pipe joints includes a frame with a conveying mechanism mounted on the frame. A diameter rolling station, a letter rolling station, a flanging station, and a tapping station are sequentially arranged along the conveying path of the conveying mechanism. The conveying mechanism sequentially transports the pipe through each station to complete the diameter rolling, letter rolling, flanging, and tapping processes. The diameter rolling station is equipped with a diameter rolling mechanism, the letter rolling station is equipped with a letter rolling mechanism, the flanging station is equipped with a flanging mechanism, and the tapping station is equipped with a tapping mechanism.

[0032] Specifically, the conveying mechanism includes an arranging track and a conveying frame. The conveying frame is connected to the frame via a slide rail, and a conveying cylinder is installed on one side of the conveying frame. The conveying frame is provided with a first conveying seat, a second conveying seat, a third conveying seat, and a fourth conveying seat in sequence along the conveying path. The first conveying seat, the second conveying seat, the third conveying seat, and the fourth conveying seat are all provided with grooves for placing positioning screw joints. The first conveying seat is used to convey the pipe fittings from the arranging track to the diameter rolling station, the second conveying seat is used to convey the pipe fittings from the diameter rolling station to the letter rolling station, the third conveying seat is used to convey the pipe fittings from the letter rolling station to the flanging station, and the fourth conveying seat is used to convey the pipe fittings from the flanging station to the tapping station. The arranging track is a sloped slide structure, and a discharge port is provided at the end of the arranging track, and a material stopper is provided on one side of the discharge port. A material stopper plate is provided on the side of the first conveying seat facing the arranging track.

[0033] The diameter rolling, letter rolling, flanging, and tapping stations are each equipped with a feeding mechanism for delivering set screw unions located on the conveying mechanism to the corresponding station. Each of the diameter rolling, letter rolling, and flanging stations is equipped with a pushing mechanism for pushing completed set screw unions within the station to the conveying mechanism. The tapping station is equipped with a drop channel, into which completed pipe fittings are dropped by the pushing mechanism.

[0034] The conveying frame described in the present application is driven by a conveying cylinder to perform reciprocating movement, and its working principle is as follows: during the conveying process, the positioning screw coupling at the discharge port is blocked by the material blocking plate and the material blocking frame. When the first conveying seat moves to the bottom of the discharge port, the positioning screw coupling falls into the groove of the first conveying seat. When the conveying frame moves back, it takes the positioning screw coupling away from the discharge port and conveys it to the diameter rolling station. The feeding mechanism of the diameter rolling station pushes the positioning screw coupling to the diameter rolling mechanism for diameter rolling processing. After the processing is completed, the pushing mechanism of the diameter rolling station pushes the positioning screw coupling that has completed the diameter rolling processing back to the conveying mechanism. At the same time, the conveying frame moves in the direction of the arrangement path, and the positioning screw coupling that has completed the diameter rolling processing falls onto the second conveying seat. The conveying method at the letter rolling station, flanging station and tapping station is similar to the above process.

[0035] Specifically, the feeding mechanism includes a feeding push block, which abuts against the end face of the positioning screw coupling to push the positioning screw coupling axially during feeding. The feeding push block is driven by a feeding cylinder. The pushing mechanism includes a plurality of push rods distributed in a ring centered on the positioning screw coupling. The push rods abut against the end face of the positioning screw coupling to push the positioning screw coupling axially during feeding. Several of the push rods are assembled on the pushing push block, which is driven by a pushing cylinder. A vertical plate is assembled on the frame, and the push rods are slidably assembled and connected to the vertical plate.

[0036] In the present application, the rolling mechanism includes a rolling ring and a rolling assembly. During feeding, the feeding mechanism sleeves the positioning screw coupling onto the rolling ring. A connecting shaft is installed in the rolling ring, and the connecting shaft is connected to a rolling drive unit via a sprocket transmission structure. The rolling assembly includes a rolling hydraulic cylinder, which is connected to a rolling frame, and a rolling wheel is installed on the rolling frame. During rolling processing, the rolling drive unit drives the rolling ring to rotate, thereby driving the positioning screw coupling to rotate, and the rolling hydraulic cylinder drives the rolling wheel to press forward, pressing out a rolling groove on the side surface of the positioning screw coupling.

[0037] In the present application, the character rolling mechanism includes a character rolling ring and a character rolling assembly. When feeding, the feeding mechanism puts the positioning screw coupling on the character rolling ring. The character rolling ring is assembled and connected to the frame through a bearing. The character rolling assembly includes a character rolling wheel, and the character rolling wheel is connected to a character rolling drive unit through a pulley transmission structure. The character rolling wheel is a D-shaped structure, and the characters to be rolled on the positioning screw coupling are set on the curved side of the D-shaped structure. In the unprocessed state, the flat side of the D-shaped structure of the character rolling wheel faces the character rolling ring to avoid interference with the action of putting the character rolling ring on the positioning screw coupling. When performing character rolling processing, the character rolling drive unit drives the character rolling wheel to rotate, and the curved side of the D-shaped structure of the character rolling wheel drives the positioning screw coupling to rotate, and at the same time rolls out the characters on the surface of the positioning screw coupling.

[0038] In order to prevent the positioning screw coupling from being worn due to rotation during the processing, the pushing mechanism in the diameter rolling station and the letter rolling station also includes a push ring, which is fixedly assembled with the diameter rolling ring or the letter rolling ring. The outer peripheral side of the push ring is provided with a rolling groove, and the end of the push rod is equipped with a bearing, and the outer ring of the bearing is assembled in the rolling groove. The feeding push block in the diameter rolling station and the letter rolling station is connected to the feeding cylinder through a bearing. The above design enables the feeding mechanism and the pushing mechanism to axially limit the positioning screw coupling during the diameter rolling processing and the letter rolling processing, while preventing the positioning screw coupling from rotating relative to the feeding push block and the push ring, and avoiding wear on the end faces of both sides of the positioning screw coupling.

[0039] In the present application, the flanging mechanism includes a cross arm, a pressing assembly and a stripper plate. The cross arm is fixedly connected to the frame, and the feeding mechanism sleeves the positioning screw coupling on the cross arm during feeding. The cross arm is provided with a plurality of recoil pins distributed in a collinear manner. The pressing assembly includes a fixed plate, which is fixed to the frame via a plurality of guide columns, a pressing cylinder is provided on the fixed plate, the pressing cylinder is connected to an upper template, the upper template is slidably assembled with the guide columns, an upper die seat is provided on the upper template, and a punching groove corresponding to the recoil pin is provided on the upper die seat, the stripper plate and the upper template.

[0040] During flanging processing, the feeding mechanism of the flanging station pushes the positioning screw coupling forward until the positioning screw coupling is sleeved on the cross arm, the downward pressure cylinder drives the upper die seat to press down, and the recoil needle punches the positioning screw coupling under the action of the downward pressure, and the downward pressure bar continues to press down, so that the positioning screw coupling forms an outward bulge with the punching hole as the center.

[0041] Furthermore, the frame is equipped with a spacer cylinder connected to a positioning spacer. As the feed mechanism pushes the set screw union onto the crossarm, the spacer cylinder drives the positioning spacer to the bottom of the crossarm. The positioning spacer prevents crossarm deformation during downward pressure and ensures the accuracy of recoil flanging.

[0042] In the present application, the tapping mechanism includes a tapping seat and a tapping machine. The tapping seat is provided with a second receiving groove for accommodating the positioning screw coupling, and the top of the second receiving groove is provided with a second positioning groove for positioning the protrusion. The tapping machine is connected to a multi-axis device, and the multi-axis device is equipped with a plurality of taps. The positioning screw coupling that has completed the flanging process is formed with a plurality of collinearly distributed protrusions, and the middle of the protrusion is a punched hole punched by the recoil needle. The tap is used to tap the punched hole in the center of the protrusion. Correspondingly, the fourth conveying seat is provided with a first receiving groove for accommodating the positioning screw coupling, and the top of the first receiving groove is provided with a first positioning groove for positioning the protrusion.

[0043] In addition, the flanging station and tapping station are equipped with oil spray nozzles to ensure efficient cooling and lubrication during the processing, thereby improving the workpiece processing quality and equipment service life.

[0044] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention is based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field fall within the protection scope of the present invention.
