Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to an automatic copper tube flaring device. Background Technology

[0002] Copper pipes are commonly used components in air conditioning and refrigeration systems for heat exchange and flow distribution. During copper pipe processing, flaring or shrinking is required. Currently, flaring devices typically consist of a hydraulic cylinder, a flaring die, and a clamp. The clamp holds the copper pipe in place, and the hydraulic cylinder drives the flaring tool towards the end of the pipe to flare it. For large-volume copper pipe flaring, the need for continuous manual clamping and unloading results in low processing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an automatic copper tube flaring device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic copper tube flaring device, comprising a machine base and a flaring mold. A horizontal hydraulic cylinder a is fixedly installed on the machine base, and the flaring mold is coaxially mounted on the piston rod of the hydraulic cylinder a. A hopper and a guide groove are fixedly installed on the upper side of the machine base. The guide groove and the flaring mold are in the same vertical plane. Opposite feeding grooves are provided on both sides of the lower part of the hopper. The lower end of the feeding groove is connected to the upper opening of the guide groove. Multiple rollers are installed along the length direction in the guide groove. The rollers are driven to rotate by a motor. The outer side of the rollers is provided with annular grooves for engaging with copper tubes. A feeding wheel is installed on the upper side of the machine base via a support. The feeding wheel is driven to rotate by a stepper motor. Multiple semi-circular grooves are provided along the circumference of the outer side of the feeding wheel. Copper tubes are inserted into the semi-circular grooves one by one and move downward along the feeding groove as the feeding wheel rotates. A pipe clamp is provided between the end of the flaring mold and the end of the guide groove to clamp the end of the copper tube.

[0005] Preferably, the pipe clamp includes an upper clamping block and a lower clamping block that engage with each other. Guide rods are fixedly installed at the four lower corners of the upper clamping block. The guide rods pass downward through the lower clamping block and the machine base. A rectangular base plate is fixedly installed between the lower ends of the guide rods. A vertically downward-facing hydraulic cylinder b is fixedly installed at the bottom of the machine base. The piston rod of the hydraulic cylinder b is fixedly connected to the base plate.

[0006] Preferably, the upper part of the feeding trough is an arc segment, and the arc segment is coaxial with the feeding wheel.

[0007] Preferably, the inner width of the feeding trough is equal to the diameter of the semi-circular trough.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses a hopper to store copper tubes after feeding, and a feeding wheel can feed the copper tubes one by one onto the roller. The roller transports the copper tubes to the left to the tube clamp for clamping, and then the bulging die expands the opening. After the bulging is completed, the tubes are output to the right. Repeating the above steps, this utility model does not require manual clamping and disassembling of copper tubes, which effectively improves the efficiency of the bulging process.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Please see Figure 1-3 This utility model provides a technical solution: an automatic copper tube flaring device, including a machine base 1 and a flaring mold 13. A horizontal hydraulic cylinder a2 is fixedly installed on the machine base 1. The flaring mold 13 is coaxially mounted on the piston rod of the hydraulic cylinder a2, and the hydraulic cylinder a2 pushes the flaring mold 13 to move horizontally. A hopper 3 and a guide groove 4 are fixedly installed on the upper side of the machine base 1. The hopper 3 is used to store copper tubes. The guide groove 4 and the flaring mold 13 are in the same vertical plane. Opposite feeding grooves 11 are provided on both sides of the lower part of the hopper 3. The lower end of the feeding groove 11 is connected to the upper opening of the guide groove 4. The upper part of the feeding groove 11 is an arc segment, which is coaxial with the feeding wheel 9.

[0015] Multiple rollers 12 are installed along the length of the guide groove 4. The rollers 12 are driven to rotate by a motor. The outer side of the rollers 12 is provided with annular grooves for engaging with copper tubes. The rollers are used for transverse conveying of copper tubes. A feeding wheel 9 is installed on the upper side of the machine base 1 via a support. The feeding wheel 9 is driven to rotate by a stepper motor. Multiple semi-circular grooves 10 are provided along the circumference of the outer side of the feeding wheel 9. Copper tubes are inserted into the semi-circular grooves 10 one by one and move downward along the feeding groove 11 as the feeding wheel 9 rotates. The inner width of the feeding groove 11 is equal to the diameter of the semi-circular grooves 10. The feeding wheel 9 distributes the copper tubes. A pipe clamp 5 is provided between the end of the bulging mold 13 and the end of the guide groove 4. The pipe clamp 5 is used to clamp the end of the copper tube and prevent it from moving due to the extrusion of the bulging mold 13 during bulging.

[0016] The pipe clamp 5 includes an upper clamping block 51 and a lower clamping block 52 that engage with each other. Guide rods 6 are fixedly installed at the four lower corners of the upper clamping block 51. The guide rods 6 pass downward through the lower clamping block 52 and the machine base 1.

A vertically downward-facing hydraulic cylinder b8 is fixedly installed at the bottom of the machine base 1. The piston rod of the hydraulic cylinder b8 is fixedly connected to the base plate 7. When the hydraulic cylinder b8 extends, it pulls the upper clamping block 51 to press down the lower clamping block 52 to clamp the copper pipe. After flaring, the roller 12 sends the copper pipe out to the right.
