Description

Technical Field

[0001] This utility model relates to the field of variable diameter aluminum alloy pipe processing technology, specifically to a variable diameter aluminum alloy pipe forming device. Background Technology

[0002] The working principle of the variable diameter aluminum alloy tube forming device is mainly based on internal high pressure forming technology. The hydraulic system applies pressure inside the tube to cause plastic deformation, and the shape is controlled by the constraint of the mold cavity.

[0003] Chinese patent CN215845073U discloses a high-pressure (water-expanded) forming mold for corrugated pipes. It includes an upper mold and a lower mold that cooperate with each other. The lower mold includes a slider; one side of the slider is bolted to the mold core, and the lower side of the slider is slidably connected to a lower base plate. A placement seat is embedded in the center of the lower base plate, and two through holes are symmetrically arranged on both sides of the placement seat, penetrating the lower base plate. A support frame is provided on the lower side of the lower base plate, and an mounting plate is fixedly installed inside the support frame. A limit cylinder is threadedly fixed to the lower side of the mounting plate. The output shaft of the limit cylinder passes through the mounting plate and is connected to a limit movable block. The upper side of the limit movable block is bolted to a limit post. Through the cooperation of the tension plate and the limit post, high forming speed and stable production are achieved, allowing for the processing of multiple corrugations at once. The number of tension plates can be adjusted according to the required number of corrugations to produce different types of corrugated pipes.

[0004] During molding, the upper and lower molds need to be bonded together. During the bonding process, the above solution cannot accurately control the bonding degree, which can easily cause the upper and lower molds to collide. Collisions can easily damage the internal parts of the equipment, affecting the service life of the equipment. Moreover, water leakage is likely to occur at the bonding point, which can easily lead to molding errors. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a variable diameter aluminum alloy tube forming device, which facilitates the operator's control of the gap between the forming mold and the placement groove, prevents the forming mold from colliding with the equipment, thereby protecting the internal components of the equipment and extending the service life of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a variable diameter aluminum alloy pipe forming device, including a processing equipment, a support frame fixedly installed on the top of the processing equipment, a fast low-pressure water injector fixedly installed on the top of the support frame, an adjusting plate fixedly installed on the bottom of the fast low-pressure water injector, a forming mold fixedly installed on the bottom of the adjusting plate, and hydraulic cylinders symmetrically fixedly installed on the top of the adjusting plate.

[0007] Preferably, a fixing ring is fixedly installed at the outer end of the molding die, a sealing gasket is fixedly installed at the bottom of the fixing ring, and a sealing groove is provided on the top of the processing equipment;

[0008] Preferably, a pressing plate is fixedly installed on one side of the fixing ring, a storage groove is provided on the top of the processing equipment, a plurality of springs are fixedly installed inside the storage groove, a baffle is fixedly installed on the top of each spring, and a sensor is fixedly installed on the inner wall of the storage groove.

[0010] Preferably, the filter assembly includes a water inlet pipe, which is fixedly installed on the top of the rapid low-pressure water injector, and a filter screen is fixedly installed inside the water inlet pipe.

[0011] Preferably, the inner wall of the water inlet pipe is provided with a threaded groove, and a threaded head is threadedly connected inside the threaded groove. A transmission pipe is fixedly installed on the top of the threaded head.

[0012] Preferably, the bottom of the rapid low-pressure water injector is through an adjusting plate, and the hydraulic cylinder is fixedly connected to the top of the support frame and passes through its interior.

[0013] Preferably, the sealing gasket and sealing groove are sized to fit each other, the contact head at the bottom of the baffle is in active contact with the sensor, and the four springs are evenly distributed inside the storage groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This solution incorporates a pressing plate, a storage slot, a spring, a baffle, and a sensor. When the molding die is adjusted downwards, the pressing plate is simultaneously adjusted. When the pressing plate contacts the baffle, it applies downward pressure. When the baffle contacts the sensor, the sensor transmits a signal to the equipment control system. This allows operators to easily control the gap between the molding die and the storage slot, while also preventing collisions between the molding die and the equipment, thus protecting the internal components and extending the equipment's lifespan.

[0016] 2. This solution uses a fixing ring, a sealing gasket, and a sealing groove. The fixing ring moves the sealing gasket downwards, adjusting it into the sealing groove, thus sealing the connection between the sealing groove and the sealing gasket. This makes the process of forming variable diameter aluminum alloy pipes using a rapid low-pressure water injection method more stable and reduces the forming error of variable diameter aluminum alloy pipes.
