Description

Technical Field

[0001] This application relates to the field of pipe processing, and in particular to a pipe flanging die. Background Art

[0002] Currently, pipe flanging refers to the process of folding a section of the pipe wall near the port along the radial direction of the pipe, either outward or inward.

[0003] The existing pipe flanging methods usually draw the flanging length on the pipe, then put on a flange, and evenly tap the inner wall of the pipe orifice with the small head of a small hammer to form a bell mouth, and then use the big head of the hammer to flatten the bell mouth.

[0004] The above-mentioned existing technical solutions have the following defects: Using a hammer to manually flange the pipe results in a high labor intensity for workers. Utility Model Content

[0005] This application provides a pipe flanging die in order to reduce the labor intensity of workers when flanging pipes.

[0006] The above technical objective of this application is achieved through the following technical solutions:

[0007] A pipe flanging die includes a base, a frame, a fixing device, and a pressing device. The fixing device is fixedly connected to the base and is used to fix the pipe. The pressing device is slidably connected to the base and is used to extrude and flange the edge of the pipe. The pressing device includes a driving member and a mounting block. The mounting block is slidably connected to the base. One end of the driving member is fixedly connected to the mounting block, and the end of the driving member away from the mounting block is fixedly connected to the frame. An insertion rod and a limiting ring are further arranged on the mounting block. One end of the insertion rod is fixedly connected to the side wall of the mounting block close to the fixing device. The limiting ring is sleeved outside the insertion rod and is fixedly connected to the mounting block. The distance between the inner wall of the limiting ring and the outer wall of the insertion rod is the width of the pipe flanging.

[0008] By adopting the above scheme, a pressing device and a fixing device are fixedly connected to the base. The fixing device is used to clamp the pipe that needs to be flanged, and the pressing device flanges one end of the pipe. When it is necessary to perform a flanging operation on the pipe, first place the pipe into the fixing device, and the fixing device clamps the pipe. Then insert the end of the pipe that needs to be flanged onto the insertion rod, start the driving member, and the driving member drives the mounting block to move towards the end close to the fixing device, thereby completing the flanging of the pipe. The distance between the inner wall of the limiting ring and the outer wall of the insertion rod is the width of the pipe flanging. Through the above settings, the effect of reducing the labor intensity of workers when flanging pipes is achieved.

[0009] Further, the fixing device includes an upper pressing member, a lower pressing member and a connecting rod. The upper pressing member and the lower pressing member are vertically corresponding. One connecting rod is correspondingly arranged at each of the two ends of the upper pressing member and the lower pressing member. Each connecting rod penetrates through the upper pressing member and the lower pressing member. The two ends of the connecting rod are respectively fixedly connected to the base and the frame body. The upper pressing member and the lower pressing member are both slidably connected to the connecting rod. The upper pressing member presses down the lower pressing member to clamp the pipe.

[0010] By adopting the above scheme, the fixing device includes an upper pressing member and a lower pressing member, which are vertically corresponding. Then, one connecting rod is correspondingly arranged at each of the two ends of the upper pressing member and the lower pressing member. Then each connecting rod penetrates through the upper pressing member and the lower pressing member. Then the two ends of the connecting rod are respectively fixedly connected to the base and the frame body so that the upper pressing member and the lower pressing member can both slide along the connecting rod. When using the fixing device to clamp the pipe, first adjust the height of the lower pressing member, then abut the pipe against the lower pressing member, and then push the upper pressing member. The upper pressing member slides along the connecting rod until the upper pressing member and the lower pressing member completely clamp the pipe.

[0011] Further, a shaping device is arranged on one side of the fixing device close to the pressing device. One shaping device is correspondingly arranged for each of the upper pressing member and the lower pressing member. Each shaping device includes a pushing rod and a shaping plate. One end of the pushing rod is fixedly connected to the pressing device, and the other end of the pushing rod is fixedly connected to the shaping plate. The shaping plate is used to extrude the fixing device to shape the flanging part of the pipe.

[0012] By adopting the above scheme, a shaping device is fixedly connected to each of the upper pressing member and the lower pressing member on the side close to the pressing device. The shaping device includes a pushing rod and a shaping plate. Then one end of the pushing rod is fixedly connected to the pressing device, and the other end of the pushing rod is fixedly connected to the shaping plate. When using this device to carry out the flanging operation on the pipe, after the pipe is clamped by the fixing device, the pressing device slides towards one end close to the fixing device. At this time, push the pushing rod, and the pushing rod drives the shaping plate to move towards the pressing device. The shaping device gives the pressing device a reverse force on the flanging of the pipe, thereby compacting the flanging area.

[0013] Further, a lifting member is arranged between the upper pressing member and the frame body. One end of the lifting member is fixedly connected to the upper pressing member, and the other end of the lifting member is fixedly connected to the frame body. The lifting member is used to drive the upper pressing member to move along the connecting rod.

[0014] By adopting the above scheme, a lifting member is arranged between the upper pressing member and the frame body. One end of the lifting member is fixedly connected to the upper pressing member, and the other end of the lifting member far from the upper pressing member is fixedly connected to the frame body. By lifting the lifting member, the positional relationship between the upper pressing member and the connecting rod is controlled. After the pipe abuts against the lower pressing member, adjust the lifting member. The lifting member drives the upper pressing member to slide on the connecting rod until the upper pressing member completely abuts against the pipe, thereby completing the limitation of the position of the pipe.

[0015] Furthermore, protective layers are fixedly connected to the positions where the upper pressing member and the lower pressing member are in contact with the pipe. The protective layers are used to protect the surface of the pipe.

[0016] By adopting the above scheme, protective layers are provided at the positions where the upper pressing member and the lower pressing member are in contact with the pipe. The protective layers are fixedly connected to both the upper pressing member and the lower pressing member. When the pipe is placed between the upper pressing member and the lower pressing member, during the process of pushing the push rod to make the upper pressing member and the lower pressing member clamp the pipe tightly, the protective layers can protect the pipe and prevent the pipe from being damaged by the upper pressing member and the lower pressing member.

[0017] Furthermore, a heating member is fixedly connected to the side wall of the pressing device close to the fixing device. The heating member is used to heat-melt the pipe inserted into the limiting ring.

[0018] By adopting the above scheme, a heating member is fixedly connected to the side wall of the pressing device. When the pipe is in contact with the pressing device, the heating member is used to heat-melt the pipe, and then the curling of the pipe is completed under the action of the pressing device and the shaping device.

[0019] Furthermore, a feeding device is arranged on the side of the fixing device away from the pressing device. The feeding device includes a feeding rack and rollers. One end of the feeding rack is fixedly connected to the base, and a roller is rotatably connected to the end of the feeding rack away from the base. The roller is used to be in contact with the pipe.

[0020] By adopting the above scheme, a feeding device including a feeding rack and rollers is arranged on the side of the fixing device away from the pressing device. One end of the feeding rack is fixedly connected to the base, and a roller is rotatably connected to the end of the feeding rack away from the base. When using this device to perform the flanging operation on the pipe, first, the pipe is brought into contact with the roller, and then the pipe is pushed so that the pipe comes into contact with the fixing device.

[0021] Furthermore, pedestals are arranged at both ends of the roller. One end of the pedestal is fixedly connected to the feeding rack, and the end of the pedestal away from the feeding rack is rotatably connected to the roller.

[0022] By adopting the above scheme, a pedestal is arranged at both ends of the roller. Then one side of the pedestal is fixedly connected to the feeding rack, and the side of the pedestal away from the feeding rack is rotatably connected to the roller. Through the above settings, the roller is rotatably connected to the feeding rack.

[0023] In summary, the present application has the following technical effects:

[0024] 1. By setting up a flanging die, a pressing device and a fixing device are fixedly connected to the base. The fixing device is used to clamp the pipe that needs to be flanged, and the pressing device flanges one end of the pipe. When flanging the pipe is required, first place the pipe into the fixing device, and the fixing device clamps the pipe. Then insert the end of the pipe that needs to be flanged onto the insertion rod, start the driving part, and the driving part drives the mounting block to move towards the end close to the fixing device, thereby completing the flanging of the pipe. The distance between the inner wall of the limiting ring and the outer wall of the insertion rod is the width of the pipe flanging. Through the above settings, the effect of reducing the labor intensity of workers when flanging the pipeline is achieved;
