Description

Technical Field

[0001] The utility model relates to the field of aluminum profile production equipment, in particular to a clamping arm device for aluminum bars. Background Art

[0002] In the field of aluminum processing technology, the handling and processing of aluminum bars is an important task. The traditional handling method is usually carried out manually or with simple mechanical equipment. This method is not only inefficient, but also easily causes damage to the aluminum bars during the handling process, affecting product quality.

[0003] In the field of aluminum profile processing technology, aluminum is extruded from aluminum bars (aluminum ingots) through an extrusion process to form aluminum profiles with a certain cross-sectional shape and high mechanical properties. Before and after the extrusion process, the aluminum bars are sent to the center line of the extruder through a bar feeder, and then the aluminum bars are extruded, or the aluminum bars after extrusion need to be moved out of the extrusion station.

[0004] However, the existing rod feeding machine simply clamps and transports the aluminum rods through two aluminum rod clamping arms. The upper and lower clamping angles and spaces of the aluminum rod clamping arms are limited. The aluminum rod clamping arms are prone to jumping when moving forward, or they are still easy to slide during the clamping process, which not only affects the handling efficiency, but also may cause the aluminum rod to fall, causing damage to the surface of the aluminum rod, and causing safety accidents. In addition, the above-mentioned rod feeding method causes inaccurate positioning of the aluminum rod, resulting in inaccurate center line alignment in the subsequent extrusion process, which seriously affects the performance and quality of the final aluminum rod product.

[0019] 4. Each movable clamping arm of the present application is composed of two tightening plates. On the one hand, the clamping area can be increased and the clamping stability can be improved. On the other hand, by designing the connecting rod, the transmission stability of the cylinder assembly can be improved through the connecting rod transmission.

[0020] 5. The design of staggered distribution of aluminum bar clamps on the same vertical plane is conducive to further increasing the pressure clamping points in different directions on the aluminum bar. This solution uses hydraulic activity to enable the upper and lower clamping arms to apply pressure in different directions to the aluminum bar instead of increasing the clamping force, thereby avoiding additional damage to the aluminum bar and ensuring product quality.

[0021] 6. The present application designs an aluminum rod positioning mechanism, and moves the aluminum rod to the vicinity of the specified position by moving the clamp arm slide. When the aluminum rod moves through the preset position, the aluminum rod positioning transmitter indicates that the aluminum rod has reached the preset position, thereby achieving precise positioning.

When the aluminum bar is clamped, each aluminum bar clamp 13 jointly applies pressure in different directions to the aluminum bar, so that the aluminum bar will not fall off during the clamping process, thereby avoiding additional damage to the aluminum bar. This design ensures the stability of the aluminum bar during the clamping process, while also reducing the cost of implementing such a mechanical clamping device, thereby achieving cost control for the enterprise. At the same time, the plurality of rollers arranged in the aluminum bar clamp 13, in a relaxed state, can slide left and right along the rollers through the guiding effect of the rollers. This design makes it more convenient to remove the aluminum bar, improves work efficiency, and also reduces the labor intensity of the operator.
