Technical Field

[0001] The utility model belongs to the technical field of copper tube hole enlargement, in particular to a port hole enlargement device used for copper tube processing. Background Art

[0002] Since copper has a low hardness, it can often be made into elbows and joints. When making joints, copper pipes generally need to be expanded into a bell mouth to facilitate a tighter connection with the connecting pipe.

[0003] At present, when copper tubes are expanded, the usual method is to manually grasp the copper tube and re-expand it with a radial drill. This method consumes a lot of manpower, has low work efficiency, and the dimensional accuracy cannot be guaranteed. In addition, the expansion head has a high hardness. If the expansion head is directly inserted into the port for expansion at high speed, the port of the copper tube may be cracked. Utility Model Content

[0004] In order to solve the above-mentioned problem that manual hole expansion is required, which consumes a lot of manpower and is inefficient, and the high strength during hole expansion can easily crack the end of the steel pipe, the utility model provides a port hole expansion device for copper pipe processing.

[0005] In order to achieve the above functions, the technical solution adopted by the utility model is as follows: a port reaming device for copper tube processing, comprising a base, a bracket is arranged on the base, a slide rail is arranged on the base, a movable seat is slidably mounted on the slide rail, a support plate is arranged on the movable seat, a rotating shaft is rotatably arranged on the support plate, a rotating plate is connected to the end of the rotating shaft, a reaming head is arranged at the center of the rotating plate, a heating wire is arranged on the rotating plate, the heating wire is in a spiral shape and is located on the outside of the reaming head, a rotating motor is installed on the movable seat, and the output end of the rotating motor is connected to the rotating shaft through a transmission belt.

[0006] As an optimal technical solution of the utility model, a fixed seat is installed on the base, and the fixed seat is symmetrically installed in two groups and located on both sides of the bracket. The fixed seat is located on the primary side close to the movable seat. An electric push rod is installed on the fixed seat, and a claw is connected to the output end of the electric push rod.

[0007] As a preferred technical solution of the utility model, a support plate is installed on the fixed seat, a limit rod is movably penetrated on the support plate, and the end of the limit rod is connected to the claw.

[0008] As a preferred technical solution of the utility model, a cylinder is installed on the base, and the output end of the cylinder is connected to the moving seat.

[0009] As a preferred technical solution of the utility model, the slide rails are provided in two groups and are arranged parallel to each other.

[0010] As a preferred technical solution of the utility model, an arc-shaped groove is transversely provided on the top wall of the bracket.

[0011] As a preferred technical solution of the present utility model, the clamping claw is arranged in a V-shaped structure.

[0012] Compared with the prior art, the utility model adopts the above structure to achieve the following beneficial effects:

[0013] 1. A spiral heating wire is arranged on the outside of the reaming head. When the reaming head moves toward the end of the steel pipe, the heating wire is first located at the outer ring of the end of the steel pipe to heat and soften it, so that the reaming head can be better inserted into the end of the steel pipe for reaming, effectively avoiding the situation where the end of the steel pipe is cracked due to high strength during reaming;

[0014] 2. Through the setting of the claws on both sides, two sets of electric push rods drive two sets of claws to clamp the end of the steel pipe close to the expanded hole, replacing manual pressing and fixing by personnel, reducing labor, and at the same time improving the stability of the steel pipe and the efficiency of expanding the hole.

The present utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1-5 As shown, the utility model provides a port reaming device for copper tube processing, comprising a base 1, a bracket 2 is arranged on the base 1, an arc-shaped groove is horizontally provided on the top wall of the bracket 2 for placing a steel tube 18, a slide rail 3 is arranged on the base 1, two groups of slide rails 3 are arranged and are arranged parallel to each other, a moving seat 4 is slidably installed on the slide rail 3, a support plate 5 is arranged on the moving seat 4, a rotating shaft 6 is rotatably arranged on the supporting plate 5, a rotating plate 7 is connected to the end of the rotating shaft 6, a reaming head 8 is arranged at the center of the rotating plate 7, a heating wire 9 is arranged on the rotating plate 7, and the heating wire 9 is spirally arranged on the outside of the reaming head 8, and the reaming head 8 is slidably arranged to the steel tube. When the end portion of 18 moves, the heating wire 9 is first located at the outer ring of the end portion of the steel pipe 18 to heat and soften it, so that the reaming head 8 can be better inserted into the end portion of the steel pipe 18 for reaming, effectively avoiding the situation where the end portion of the steel pipe 18 is cracked due to the high strength during reaming. A rotating motor 10 is installed on the moving seat 4, and the output end of the rotating motor 10 is connected to the rotating shaft 6 through a transmission belt 11. The rotating motor 10 drives the rotating shaft 6 to rotate through the transmission belt 11, thereby driving the reaming head 8 and the heating wire 9 on the rotating plate 7 to rotate, thereby realizing high-speed rotation reaming of the end portion of the steel pipe 18 after heating and softening.

[0024] like Figure 1 , 2As shown in FIG. 4 , a fixed seat 12 is installed on the base 1. Two groups of fixed seats 12 are symmetrically installed and located on both sides of the bracket 2. The fixed seat 12 is located on the primary side close to the movable seat 4. An electric push rod 13 is installed on the fixed seat 12. The output end of the electric push rod 13 is connected to a claw 14. The claw 14 is a V-shaped structure. The two groups of electric push rods 13 drive the two groups of claws 14 to clamp the end of the steel pipe 18 close to the expanded hole.

[0025] like Figure 5 As shown, a support plate 15 is installed on the fixed seat 12, and a limit rod 16 is movably penetrated on the support plate 15. The end of the limit rod 16 is connected to the claw 14. When the electric push rod 13 drives the claw 14 to move, the limit rod 16 assists in limiting the movement of the claw 14 to ensure stability.

[0026] like Figure 1 , 2 As shown in FIG. 4 , a cylinder 17 is installed on the base 1 , and the output end of the cylinder 17 is connected to the moving base 4 .
