Description

Technical Field

[0001] The utility model relates to the technical field of copper tube processing, in particular to a trimming device for copper tubes. Background Art

[0002] Copper tubes, also known as red copper tubes, are a type of non-ferrous metal tubes and are seamless tubes produced by pressing and drawing. Copper tubes have the characteristics of good electrical conductivity and thermal conductivity. They are the main materials for conductive accessories and heat dissipation accessories of electronic products, and have become the first choice for modern contractors in the installation of tap water pipes, heating, and refrigeration pipes in all residential commercial housing.

[0003] After processes such as truncation processing and expansion / contraction processing of copper tubes, the edges of the copper tube openings are often not flat enough, and the edges of the copper tube openings need to be trimmed. Traditional methods for trimming the edges of copper tube openings mostly involve workers using edge-cutting knives and grinding tools for manual trimming. Such methods not only have low efficiency but also are prone to hand injuries. Summary of the Utility Model

[0005] A trimming device for copper tubes includes a processing table, a transfer and positioning mechanism, and a trimming mechanism installed on the processing table. The transfer and positioning mechanism includes a first limiting plate, a first connecting frame, a rack, a first guide rail, a second limiting plate, a second connecting frame, a second guide rail, a cylinder, and a second motor. The first guide rail is installed on one side of the placement groove of the processing table. The cylinder is installed on the outer wall of one side of the processing table. The second guide rail is installed at the output end of the cylinder and is inserted into the processing table through the limiting arms at both ends for stability. The first limiting plate and the second limiting plate are arranged oppositely, and the second limiting plate is movably connected to the first limiting plate through a connecting arm. The first connecting frame is installed on one side of the first limiting plate, and the first limiting plate can slide along the first guide rail through the first connecting frame. The second connecting frame is installed on one side of the second limiting plate, and the second limiting plate can slide along the second guide rail through the second connecting frame. The rack is fixed on the first connecting frame. The second motor is installed in the slot of the processing table and is engaged with the rack through the gear at its output end.

[0006] By adopting the above technical solution, it is convenient to place the copper tube, limit the copper tube, and adapt to copper tubes of different lengths for trimming treatment.

[0008] By adopting the above technical solution, it is convenient to trim the copper tube.

[0009] Arc-shaped grooves are provided at the opposite surfaces of the upper end plates and the lower end plates of the first limiting plate and the second limiting plate.

[0010] By adopting the above technical solution, the copper tube can be better limited and clamped.

[0011] The connecting arms are fixed at the four corners of the second limiting plate and penetrate through the first limiting plate.

[0012] By adopting the above technical solution, the first limiting plate and the second limiting plate are stably connected, so as to facilitate the limitation of the copper tube.

[0013] The second motor is arranged at one end close to the processing table.

Then, the second motor can be driven to drive the first guide rail to move through the gear at its output end. The first connecting frame moves horizontally along the rack, and the second connecting frame moves horizontally along the second guide rail, thereby driving the copper tube between the first limiting plate and the second limiting plate to be transferred directly below the trimming machine. Then, the first motor is driven to drive the moving seat to move downward through the lead screw, and the moving seat drives the trimming machine to move synchronously, which is convenient for placing the copper tube, limiting the copper tube, and adapting to copper tubes of different lengths for trimming.

[0019] 2. Arc-shaped grooves are provided at the opposite surfaces of the upper end plates and the lower end plates of the first limiting plate and the second limiting plate.

Specific embodiments

[0024] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model.

[0025] Referring to Figures 1-3 , a trimming device for copper tubes includes a processing table 1 and a transfer and positioning mechanism and a trimming mechanism installed on the processing table 1. The moving and positioning mechanism includes a first limit plate 7, a first connecting frame 8, a rack 9, a first guide rail 10, a second limit plate 11, a second connecting frame 13, a second guide rail 14, a cylinder 16 and a second motor 17. The first guide rail 10 is installed on one side of the placement groove 101 of the processing table 1. The cylinder 16 is installed on the outer wall of one side of the processing table 1. The second guide rail 14 is installed at the output end of the cylinder 16 and is inserted into the processing table 1 through the limit arms 15 at both ends for stability. The first limit plate 7 and the second limit plate 11 are arranged oppositely, and the second limit plate 11 is movably connected to the first limit plate 7 through the connecting arm 12. The first connecting frame 8 is installed on one side of the first limit plate 7, and the first limit plate 7 can slide along the first guide rail 10 through the first connecting frame 8. The second connecting frame 13 is installed on one side of the second limit plate 11, and the second limit plate 11 can slide along the second guide rail 14 through the second connecting frame 13. The rack 9 is fixed on the first connecting frame 8. The second motor 17 is installed in the groove of the processing table 1 and meshes with the rack 9 through the gear at its output end.

[0026] The trimming mechanism includes a support 2, a first motor 3, a lead screw 4, a moving seat 5 and a trimming machine 6. The first motor 3 is installed at the top of the support 2. The lead screw 4 is installed at the output end of the first motor 3. The moving seat 5 is in transmission connection with the lead screw 4 and moves up and down along the support 2. The trimming machine 6 is installed on the moving seat 5;

[0027] The copper tubes can be vertically placed one by one between the first limiting plate 7 and the second limiting plate 11, and then the driving cylinder 16 is driven to push the second guide rail 14. The second guide rail 14 pushes the second limiting plate 11 to approach the first limiting plate 7 through the limiting arm 15, and the first limiting plate 7 and the second limiting plate 11 clamp the copper tubes. Then, the second motor 17 can be driven to move the first guide rail 10 through the gear at its output end. At this time, the first connecting frame 8 moves horizontally along the rack 9, and the second connecting frame 13 moves horizontally along the second guide rail 14, thereby driving the copper tubes between the first limiting plate 7 and the second limiting plate 11 to be transferred to directly below the trimming machine 6.

[0028] After all the copper tubes clamped between the first limiting plate 7 and the second limiting plate 11 are trimmed, the cylinder 16 can be operated to pull the second guide rail 14, so that the second limiting plate 11 moves away from the first limiting plate 7 to remove the copper tubes.

[0029] The connecting arms 12 are fixed at the four corners of the second limiting plate 11 and penetrate through the first limiting plate 7; arc-shaped grooves are provided on the opposite surfaces of the upper end plates and the lower end plates of the first limiting plate 7 and the second limiting plate 11. The arc-shaped grooves are provided to facilitate the first limiting plate 7 and the second limiting plate 11 to jointly clamp and limit the copper tubes. Arc-shaped grooves are provided at both the upper end and the lower end of the first limiting plate 7 and the second limiting plate 11, so that the copper tubes are clamped more stably.

[0030] The second motor 17 is arranged at one end close to the processing table 1; a certain length is left without arc-shaped grooves on one side of both the first limiting plate 7 and the second limiting plate 11. Through the drive of the second motor 17, the first limiting plate 7 and the second limiting plate 11 move in one direction, and the copper tubes placed at the arc-shaped grooves of the first limiting plate 7 and the second limiting plate 11 can all be moved to directly below the trimming machine 6 for trimming treatment by the trimming machine 6.

[0031] A notch corresponding to the height of the connecting arm 12 is also provided on the processing table 1. When the second limiting plate 11 approaches the first limiting plate 7, the connecting arm 12 can extend into the notch and move in the notch.
