Description

Technical Field

[0001] This utility model relates to the technical field of aluminum pipe processing, and in particular to an integrated machine for flaring and grooving aluminum pipes. Background Technology

[0002] The aluminum tube is tubular in shape, with one end being flared to a diameter greater than the original diameter. A groove is also machined around the flared end to facilitate assembly. The traditional processing method involves step-by-step processing: the flaring is completed first, the material is collected, and then the collected tube is stored for the next processing step.

[0003] Existing flaring and grooving integrated machines, such as the one disclosed in utility model patent application number 201922062803.0 for automotive pipe fittings, mainly include a support plate. One end of the support plate is bolted to one end face of the base, and one end of the connecting mounting plate is bolted to the upper surface of the support plate. One end of the cylinder is bolted to the upper surface of the connecting mounting plate, and one end of the grooving push rod is fixed to one end face inside the cylinder by embedding. In use, one end of the automotive pipe fitting is installed at one end of the pipe fitting fixing device, with the flared end of the automotive pipe fitting facing upwards. The cylinder is powered on and started, and the grooving push rod moves up and down. When the grooving push rod descends, the grooving device and grooving blade groov the flared end of the rotating automotive pipe fitting, cutting a groove on the rotating automotive pipe fitting.

[0004] However, most existing equipment does not heat the aluminum tubes, making them prone to cracking during cold working. Furthermore, waste chips can easily remain inside the aluminum tubes after grooving, affecting their subsequent use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an integrated machine for flaring and grooving aluminum tubes, which can not only heat the aluminum tubes before flaring and grooving to prevent cracking, but also blow out the waste residue remaining in the aluminum tubes in time after processing.

[0006] This utility model discloses an integrated flaring and grooving forming machine for aluminum tube fittings, comprising a receiving mechanism; it also includes a fixing mechanism, a moving mechanism, a flaring mechanism, a heating mechanism, and a blowing mechanism. The fixing mechanism is installed on the receiving mechanism and fixes the aluminum tube fitting; the moving mechanism is installed on the receiving mechanism and drives the flaring and blowing mechanisms to move; the flaring mechanism is installed on the moving mechanism and flares and grooves the aluminum tube fitting; the heating mechanism is installed on the flaring mechanism and heats the aluminum tube fitting; the blowing mechanism is installed on the moving mechanism and blows out residual waste debris inside the aluminum tube fitting. The operator fixes the aluminum tube fitting in the receiving mechanism to the fixing mechanism. The moving mechanism moves the flaring and blowing mechanisms closer together. After the heating mechanism heats the aluminum tube fitting, the flaring mechanism flares and grooves it. Then, the fixing mechanism releases the fixation of the aluminum tube fitting, and the moving mechanism moves the flaring and blowing mechanisms away. The aluminum tube fitting moves with the blowing mechanism, which then blows out the waste debris inside the aluminum tube fitting. Finally, the operator removes the aluminum tube fitting from the blowing mechanism.

[0007] Preferably, the storage mechanism includes a workbench, a control switch, a locking strip, a storage box, and handles. The bottom of the workbench is connected to the ground and has a feed inlet. The control switch is installed on the workbench, the locking strip is installed at the feed inlet, the storage box is slidably installed on the locking strip, and a partition is provided inside the storage box. Both sets of handles are installed on the storage box. The aluminum tube to be processed is placed inside the storage box. The worker places the aluminum tube on the fixing mechanism and then presses the control switch to control the fixing mechanism to fix the aluminum tube. After processing, the aluminum tube is removed from the blowing mechanism and placed back into the other side of the partition inside the storage box. When all processing is completed, the worker pulls the two sets of handles to slide the storage box out.

[0008] Preferably, the fixing mechanism includes a fixed platform, two sets of guide columns, two sets of hydraulic cylinders, and two sets of clamping plates. The fixed platform is installed on the workbench, both sets of guide columns are installed on the fixed platform, the two sets of hydraulic cylinders are installed opposite each other on the fixed platform, and the two sets of clamping plates are slidably installed on the two sets of guide columns and connected to the top of the two sets of hydraulic cylinders respectively. The operator places the aluminum tube between the two sets of clamping plates, and the control switch controls the start of the two sets of hydraulic cylinders. The two sets of hydraulic cylinders push the two sets of clamping plates closer to hold the aluminum tube.

[0009] Preferably, the moving mechanism includes a servo motor, a first reducer, and a bidirectional lead screw. A moving slot is provided on the worktable. The servo motor is mounted on the worktable, and the output end of the servo motor is connected to the input end of the first reducer. The output end of the first reducer is connected to the input end of the bidirectional lead screw. The bidirectional lead screw is rotatably mounted in the moving slot of the worktable. When the servo motor is started, it drives the bidirectional lead screw to rotate through the first reducer. The bidirectional lead screw drives the flaring mechanism and the blowing mechanism to move closer, facilitating the heating, flaring, and grooving of the aluminum tube. After processing is completed, the bidirectional lead screw reverses, driving the flaring mechanism and the blowing mechanism away, facilitating the blowing mechanism to blow out the waste debris inside the aluminum tube.

[0010] Preferably, the flaring mechanism includes a first slider, a motor, a second reducer, a drive shaft, a flaring head, and a threading cutter. The first slider is slidably mounted in the movable slot of the worktable and is threadedly connected to a bidirectional lead screw. The motor is mounted on the first slider, the second reducer is mounted on the first slider, the drive shaft is rotatably mounted on the first slider, the flaring head is mounted on the drive shaft, and the threading cutter is mounted on the flaring head. The bidirectional lead screw drives the first slider to approach the aluminum tube, starts the motor, and the motor drives the drive shaft to rotate through the second reducer. The drive shaft drives the flaring head to rotate to flare the aluminum tube, and at the same time, the flaring head drives the threading cutter to rotate to slot the aluminum tube.

[0011] Preferably, the heating mechanism includes a protective sleeve, a control panel, and a resistance wire. The protective sleeve is installed on the first slider, the bottom end of the control panel is connected to the top end of the first slider, and the resistance wire is installed on the first slider and sleeved on the outside of the protective sleeve. The operator adjusts the heating temperature of the resistance wire through the control panel according to the thickness of the aluminum tube. The control panel heats the aluminum tube to prevent it from cracking. The protective sleeve can prevent the aluminum tube from breaking and splashing onto the resistance wire during the flaring process, thus protecting the resistance wire.

[0012] Preferably, the purging mechanism includes a second slider, an air pump, an air supply pipe, a valve, and a rubber sealing ring. The second slider is slidably installed in the moving groove of the worktable and is connected to the bidirectional lead screw via a thread. The bottom end of the air pump is connected to the top end of the second slider. The air supply pipe is installed inside the second slider and communicates with the exhaust port of the air pump. The valve is installed on the air supply pipe, and the rubber sealing ring is installed on the air supply pipe. The bidirectional lead screw drives the second slider to approach the aluminum tube, so that the aluminum tube is inserted into the air supply pipe. After processing, due to the friction between the rubber sealing ring and the aluminum tube, it is easy to move the aluminum tube. When the aluminum tube is removed from the protective sleeve, the valve is opened, and the air pump delivers compressed air through the air supply pipe into the aluminum tube to blow out the waste inside the aluminum tube.
