Description

Technical Field

[0001] The invention relates to the technical field of aluminum tube flanging, and in particular to an aluminum tube flanging device and a process method. Background Art

[0002] In some usage scenarios of aluminum tubes, the front end of the aluminum tube needs to be connected to some auxiliary parts. In order to facilitate installation, one end of the aluminum tube needs to be flanging; at the same time, flanging the aluminum tube can also make the end face of the aluminum tube smoother, avoiding safety accidents caused by the aluminum tube being too sharp; the flanging process of the aluminum tube can also increase the stability of the aluminum tube structure, thereby reducing the probability of deformation of the end face of the aluminum tube during use; therefore, in some application scenarios, flanging the aluminum tube is a very critical process.

[0003] The existing aluminum tube flanging equipment generally uses stamping to flanging the end face of the aluminum tube. Although this method is highly efficient and has a fast processing speed, it is easy to cause cracking and rupture at the edge due to excessive impact during the stamping process. At the same time, the existing aluminum tube flanging equipment cannot automatically adapt to aluminum tubes of different lengths and diameters, and manual replacement of clamps of different sizes is required. Therefore, there is a need for an aluminum tube flanging equipment and process method that can perform flanging processing on aluminum tubes of different specifications and effectively reduce the risk of cracking at the edge to solve the shortcomings of the existing aluminum tube flanging equipment.

[0004] For example, the patent with announcement number CN214349198U provides an aluminum tube flanging die, which includes a lower die and an upper die. The lower die is driven by a motor to rotate a lead screw, and the lead screw drives a slider to slide to the right, so that the connecting rod drives the vertical rod to move downward and drives the arc plate to move upward to eject the aluminum tube after flanging. This application can eject the aluminum tube after flanging, so that it is easy to take it out manually, avoid the occurrence of safety accidents, and speed up production efficiency. Although this solution can facilitate manual picking by moving the vertical rod downward and the arc plate upward, the aluminum tube placed in the semicircular groove cannot adjust the clamping position according to the size, so that the clamping function of aluminum tubes of different specifications cannot be realized; this solution can only process one aluminum tube at a time, and cannot perform stamping processing on multiple aluminum tubes, so it cannot improve the processing efficiency; at the same time, a large impact is required to perform a flanging forming on an aluminum tube, which can easily cause the flanging to crack. If a flanging stamping is decomposed into multiple flanging stampings, the impact force on the aluminum tube at a time can be reduced, which can effectively reduce the probability of cracking during the flanging process; the flanging process of this solution requires two power sources for control, and cannot achieve integrated control of a single power source, thereby failing to reduce the difficulty of maintenance and the difficulty of direct coordinated control of the power source.

[0013] An aluminum tube flanging process method, such as the above-mentioned aluminum tube flanging equipment, comprises the following steps: Step 1: First open the inlet folding plate on the transposition assembly, and then insert the aluminum tube into the second semicircular groove on the transposition slide to realize the loading of the aluminum tube, and then manually rotate the stamping ball on the stamping device, and the stamping ball drives the stamping screw and the stamping fixed plate to slide in the direction of the aluminum tube, so that the side of the stamping fixed plate contacts the front end of the aluminum tube, thereby adapting to aluminum tubes of different lengths; Step 2: The electric push rod on the compacting device drives the hydraulic oil from the rear oil tank into the first hydraulic control pipe and the hydraulic control oil cylinder of the hydraulic control device, and then the hydraulic oil drives the hydraulic control plunger to move forward, and the hydraulic control plunger drives the vertical slide bar to slide upward through the hydraulic control connecting rod, and the vertical slide bar drives the transposition slide seat on the transposition assembly to slide upward, so that the second semicircular groove at the upper end of the transposition slide seat and the first semicircular groove at the lower end of the compacting shell are closed; Step 3: When the hydraulic plunger slides forward to the maximum distance, the pressure assembly will be connected with the interior of the hydraulic oil cylinder, and the hydraulic oil will enter the pressure shell from the hydraulic oil cylinder. The pressure will push the pressure plunger out of the pressure collar, so that the hydraulic oil will flow from the pressure shell into the oil supply pipe and the compacting cylinder. At this time, the hydraulic oil drives the compacting plunger to extend forward in the compacting cylinder, and the compacting plunger drives the compacting slide plate to press down through the first connecting rod.

The hydraulic oil will enter the second hydraulic control pipe while entering the first hydraulic control pipe, and then flow into the stamping pipeline through the second hydraulic control pipe and the stamping through hole. At this time, the hydraulic oil will flow from the stamping pipeline into the second hydraulic push rod, the third hydraulic push rod, and the fourth hydraulic push rod, respectively, so that the second hydraulic push rod, the third hydraulic push rod, and the fourth hydraulic push rod are extended forward respectively, to realize the multiple stamping function in the process of aluminum tube transfer; Step 7: When the processed aluminum tube is aligned with the discharge port, the hydraulic oil enters the first hydraulic push rod through the stamping pipe, causing the first hydraulic push rod to extend forward. The first hydraulic push rod will push the aluminum tube directly out of the discharge port to realize the processed discharge function.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The compaction device drives the hydraulic oil from the rear oil tank into the hydraulic control device through the electric push rod. When the pressure reaches a certain level, the hydraulic oil enters the compaction oil cylinder from the hydraulic control device, so that the compaction plunger extends forward in the compaction oil cylinder. The compaction plunger drives the compaction slide plate downward through the first connecting rod. The compaction slide plate drives the second clamping plate to flip downward through the adjustment slider and the first clamping plate. The second clamping plate and the second semicircular groove will clamp the aluminum tube to achieve the clamping function of aluminum tubes of different specifications. (2) The hydraulic control device, when the hydraulic oil flows into the hydraulic control oil cylinder, the hydraulic oil drives the hydraulic control plunger to extend forward. The hydraulic control plunger drives the shifting slide seat to slide downward through the hydraulic control connecting rod and the vertical slide rod, so that the inclined plug column drives the aluminum tube to move to the next second semicircular groove to achieve the transfer function. (3) The hydraulic oil will enter the second hydraulic control pipe at the same time as entering the first hydraulic control pipe, and then flow into the stamping pipe through the second hydraulic control pipe and the stamping through hole. At this time, the hydraulic oil will flow from the stamping pipe into the second hydraulic push rod, the third hydraulic push rod, and the fourth hydraulic push rod respectively, so that the second hydraulic push rod, the third hydraulic push rod, and the fourth hydraulic push rod are extended forward respectively, so as to realize the aluminum tube transfer function and the multiple stamping function at the same time.
