[0002] In the production process of some existing pipe fittings, punching needs to be carried out on them. The punching process is to punch through holes on the pipe fittings through punching tools; after punching is completed, shaping of the through holes is required. The shaping process is to insert a shaping tool into the through hole. Through the insertion of the shaping tool, defects such as burrs at the edge of the through hole can be removed, improving the processing quality of the through hole.

[0003] In the prior art, the punching process and the shaping process need to be completed on two different sets of equipment respectively. The operator needs to first clamp the pipe fitting onto the punching device and process through holes on the pipe fitting through the punching device; then clamp the pipe fitting onto the shaping equipment and shape the through hole through the shaping equipment. This separate processing method makes it impossible to complete the punching and shaping processes on the same device. In actual production, completing the above processing operations requires occupying two workstations, which is not conducive to the compactness of the production line. Moreover, after the pipe fitting is completed with punching processing, it is necessary to transfer the pipe fitting to the shaping processing station, increasing the complexity of the processing process.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0020] As Figures 1 to 3 shown, a pipe fitting punching and shaping device includes a processing mechanism. The processing mechanism includes a fixed clamping block 8 and a movable clamping block corresponding to the fixed clamping block 8. The movable clamping block is connected to a movable clamping block driving oil cylinder 10. The movable clamping block is driven to move by the movable clamping block driving oil cylinder 10. The movable clamping block driving oil cylinder 10 is arranged on one side of the movable clamping block close to the fixed clamping block 8. Clamping grooves 13 are provided on both the fixed clamping block 8 and the movable clamping block. The cross-section of the clamping groove 13 is semi-circular, and the radius of the clamping groove 13 matches the radius of the pipe fitting 20. An punching oil cylinder 6 is arranged above the fixed clamping block 8. An punching tool 7 is connected to the punching oil cylinder 6. A punching tool guiding hole is provided on the fixed clamping block 8. One end of the punching tool guiding hole communicates with the clamping groove 13 on the fixed clamping block 8. The punching tool 7 extends into the punching tool guiding hole. Among them, the processing mechanism further includes a support base 5, and the punching oil cylinder 6 is fixedly arranged on the support base 5.

[0021] One side of the fixed clamping block 8 is provided with a shaping oil cylinder 9, and a shaping tool is connected to the shaping oil cylinder 9. A shaping tool guiding hole 14 is provided on the fixed clamping block 8. One end of the shaping tool guiding hole 14 communicates with the clamping groove 13 on the fixed clamping block 8. The shaping tool extends into the shaping tool guiding hole 14. The interval angle between the shaping tool guiding hole 14 and the punching tool guiding hole is 90 degrees.

[0022] A feeding mechanism is arranged on one side of the processing mechanism, and a rotation adjustment mechanism is arranged on the other side of the processing mechanism. The rotation adjustment mechanism is used to clamp one end of the pipe fitting 20 and drive the pipe fitting 20 to rotate around its own central axis.

[0023] Among them, the feeding mechanism includes a second moving device 11 and a feeding clamp 12 arranged on the second moving device 11. The feeding clamp 12 is driven to move by the second moving device 11. Preferably, the feeding clamp 12 adopts a cylinder clamp.

[0024] The rotation adjustment mechanism includes a first moving device 1. An installation seat 2 is arranged on the first moving device 1. A rotation driving device 3 is arranged on the installation seat 2. A rotation clamp 4 is connected to the rotation driving device 3. The rotation driving device 3 drives the rotation clamp 4 to rotate around the horizontal axis. Preferably, the rotation driving device 3 adopts a servo motor, and the rotation clamp 4 adopts a cylinder clamp.

[0025] After the rotating clamping fixture 4 clamps the pipe fitting 20, the pipe fitting can be rotated by the rotation driving device 3. When two or more holes need to be processed simultaneously at the same axial position on the pipe fitting, after one hole is processed, the rotation driving device 3 can drive the pipe fitting to rotate and turn the pipe fitting to the next position point where a hole needs to be processed.

[0026] In this embodiment, both the first moving device 1 and the second moving device 11 are electric guide rails. In addition, the first moving device can also use devices such as cylinders and hydraulic cylinders as driving parts to drive the mounting seat 2 to move. Similarly, the second moving device 11 can also use devices such as cylinders and hydraulic cylinders as driving parts to drive the feeding clamping fixture 12 to move.

[0027] For the convenience of tool replacement, the punching tool 7 and the punching oil cylinder 6 are connected by a quick-release connection mechanism, and the sizing tool and the sizing oil cylinder are also connected by a quick-release connection mechanism to ensure the quick disassembly and replacement of the tools.

[0028] In addition, during the punching process, the waste material being punched down will pass through the waste material detection device during its falling process. The waste material detection device includes a group of infrared opposed sensors. When the waste material passes between the sensors, the sensors can detect the falling of the waste material. If the falling of the waste material is not detected after punching is completed, the control system will issue a fault alarm.

[0029] When this device performs a punching operation on the pipe body, the specific method is as follows:

[0030] The pipe body is clamped on the feeding clamping fixture 12, and the second moving device 11 drives the pipe body to move so that the pipe body moves between the fixed clamping block 8 and the movable clamping block. Then, the movable clamping block driving oil cylinder 10 drives the movable clamping block to move and clamp the pipe body;

[0031] The punching oil cylinder 6 drives the punching tool 7 to move downward and punch a hole in the pipe body to form a through hole on the pipe body; after punching is completed, the punching tool 7 moves upward to reset; the movable clamping block moves away from the fixed clamping block 8 and loosens the pipe body;

[0032] The first moving device 1 drives the rotating clamping fixture 4 to move towards the pipe body and makes the rotating clamping fixture 4 clamp one end of the pipe body. Subsequently, the feeding clamping fixture 12 loosens the pipe body, and the first rotation driving device 3 drives the rotating clamping fixture 4 to rotate. When the through hole on the pipe body rotates to align with the sizing tool, the first rotation driving device 3 stops; then the feeding clamping fixture 12 clamps the pipe body, the rotating clamping fixture 4 loosens the pipe body, the movable clamping block driving oil cylinder 10 drives the movable clamping block to move and clamp the pipe body, and the sizing oil cylinder 9 drives the sizing tool to move. After the sizing tool extends into the through hole on the pipe body, it then withdraws from the through hole;

[0033] Finally, the movable clamping block releases the pipe body, and the second moving device 11 drives the pipe body to move and makes the pipe body exit from between the fixed clamping block 8 and the movable clamping block, thus completing the punching operation and the shaping of the through hole.

[0034] The present invention has the following advantages: The utility model can simultaneously complete the punching and shaping processes of the pipe fitting 20 on the same device, without occupying two workstations, which is beneficial to improving the compactness of the production line; and after the punching of the pipe fitting 20 is completed, the pipe fitting 20 is automatically rotated from the punching angle state to the shaping angle state by the rotation adjustment mechanism, without manual operation, improving the processing efficiency.
