Description

Technical Field

[0001] The present invention relates to the field of metal processing equipment, in particular to a twisting and shaping machine. Background Art

[0002] In the machining industry, the twisting and shaping process is crucial for the forming and straightening of metal pipes and shafts. However, current twisting and shaping equipment on the market suffers from significant deficiencies. Most traditional equipment relies heavily on manual operation, requiring manual intervention for everything from workpiece clamping and positioning to twisting angle adjustment. This not only results in low production efficiency but also hinders precise control of force and angle, leading to poor product consistency and high scrap rates. Furthermore, traditional equipment's rigid structure and limited functionality make it difficult to adapt to diverse processing needs. Working with workpieces of varying sizes and shapes requires not only frequent replacement of entire molds but also time-consuming and complex parameter adjustments, significantly limiting production efficiency and significantly increasing costs. Furthermore, some equipment utilizes simple mechanical transmission structures and lacks precise guiding and positioning devices. This can easily cause vibration and displacement during the twisting operation, severely impacting shaping accuracy. Over time, wear and tear of mechanical components exacerbate precision losses, leading to a continuous decline in product quality. Existing equipment often operates as independent working units, and it is difficult to achieve efficient connection between processes such as workpiece loading, clamping, twisting, and unloading. It is impossible to build an automated production line, which is seriously out of touch with the urgent demand of modern manufacturing for efficient and continuous production.

[0028] The working principle of the present invention is as follows: First, the second motor 34 drives the second lead screw 35 to rotate, causing the movable base 3 to slide along the guide rod 37. This precisely adjusts the distance between the movable base 3 and the fixed base 2 to accommodate aluminum tubes of varying lengths. After the distance is adjusted, a matching clamping die 4 is selected based on the tube's diameter, cross-sectional shape, and other parameters. The matching lower die 42 is secured to the bottom of the fixed base 2's through-hole chamber 21 and to the lower clamping plate 12 of the movable base 3. The upper die 41 is connected to the lower pressure plate 22 of the fixed base 2 and the upper clamping plate 15 of the movable base 3, respectively.

[0029] The first hydraulic cylinder 23 of the fixed base 2 drives the lower pressure plate 22 to descend, driving the upper mold 41 and the lower mold 42 to close, clamping one end of the aluminum tube; the first motor 16 of the movable base 3 drives the first screw 14 to rotate, and the upper clamping plate 15 slides down along the first guide column 13, driving the upper mold 41 and the lower mold 42 of the lower clamping plate 12 to close, clamping the other end of the aluminum tube.

[0030] The second and third hydraulic cylinders 32 and 39 on either side of the movable base 3 work in concert, pushing the rotating drum 1 around the bearing 18 via the connecting ring 17. This, in turn, drives the turntable 11, lower clamping plate 12, and upper clamping plate 15, twisting the right end of the aluminum tube relative to the left, completing the twisting process. The first hydraulic cylinder 23 and first motor 16 respectively drive the upper mold 41 of the fixed base 2 and movable base 3 upward, freeing both upper molds from the aluminum tube. Subsequently, the third motor 27 at the bottom of the placement plate 24 drives the third lead screw 26, raising the upper plate 5 along the second guide post 25 until its pulley 58 contacts the surface of the aluminum tube, lifting the tube from the lower mold 42 of the fixed base 2 and separating it from the lower mold, leaving it suspended in the air and ready for subsequent transport.

[0031] The fourth motor 57 of the right slide 52 drives the fourth lead screw 53, causing the motorized belt mechanism 54 of the left and right slides 51 and 52 to translate along the first sliding slot 56 in the opposite direction toward the aluminum tube. The mating block 55 moves with the lead screw and drives the belt mechanism to clamp the aluminum tube. Simultaneously, the fifth motor 66 of the workbench 6 drives the fifth lead screw 61, adjusting the belt conveyor 64 on the work plate 63 to the designated position. The motorized belt mechanism 54 and the belt conveyor 64 are activated and operate synchronously, using the friction of the belts to transport the twisted and shaped aluminum tube forward, completing the unloading process.
