Problems solved by technology

[0002] At present, domestic small and medium-sized aluminum profile offline stretching and straightening machines mostly adopt the center-loaded stretching method with no buffer and double cylinders inverted. When the material is broken, the impact energy is mainly absorbed by the main stretching cylinder; but for heavy-duty aluminum profiles Straight machine, due to the relatively large impact energy when the material is cut off, simply absorbing the impact energy by the main stretching cylinder will bring great impact to the equipment and hydraulic system, seriously affecting the service life of the equipment
At the same time, due to the heavy moving parts of the heavy-duty aluminum profile stretching and straightening machine and the large cross-sectional size of the stretched aluminum profile, a new structural form is required to meet its use requirements

Embodiment 1

[0019] This embodiment provides a kind of heavy-duty aluminum extrusion straightening machine, comprising equipment foundation 9, main stretching oil cylinder 5, frame 3 located on equipment foundation 9, stretching head 6 and tailstock 2, stretching head 6 and the tailstock 2 are arranged at the two ends of the frame 3 respectively, the stretching head 6 and the tailstock 2 are provided with jaws, the frame 3 can move along the stretching direction relative to the equipment foundation 9, and the main pull Stretching oil cylinder 5 is located between frame 3 and stretching head 6, and the cylinder tail of this main stretching oil cylinder 5 is supported on frame 3 front ends, and the other end withstands stretching head 6, and described tailstock 2 and frame 3 rigidly connected, the stretching head 6 and the tailstock 2 are all slidably connected with the equipment foundation 9.

[0020] like figure 1 As shown, when the heavy-duty aluminum profile stretching straightener is s...

Embodiment 2

[0025] On the basis of Embodiment 1, this embodiment provides a heavy-duty aluminum extrusion straightening machine, the equipment foundation 9 is provided with a sliding support 10 and a guide rail 4, and the frame 3 is located on the sliding support 10, the stretching head 6 and the tailstock 2 are all provided with traveling wheels that cooperate with the guide rail 4.

[0026] The jaws are inclined pair of clamps, and the included angle with the horizontal direction is 20-25°. Ensure that the profile will not slip when stretched.

[0027] It also includes an idle stroke buffer oil cylinder 8, the main stretching oil cylinder 5 is a plunger cylinder, the tail of the empty stroke buffer oil cylinder 8 is fixedly connected with the stretching head 6, and one end of the piston rod passes through the main stretching oil cylinder 5 and the machine. Frame 3 is connected.

[0028] It also includes a buffer reset oil cylinder 1 and a frame positioning oil cylinder 7, the buffer r...

Abstract

The invention provides a heavy-duty aluminum profile stretching straightening machine, which comprises equipment foundation, main stretching oil cylinder, frame set on the equipment foundation, stretching head and tailstock, both of which are equipped with Jaws, the frame can slide relative to the equipment foundation along the stretching direction, the main stretching oil cylinder is set between the frame and the stretching head, the tail of the main stretching oil cylinder is against the front end of the frame, and the other end is against the front end of the frame. The stretching head and the tailstock are rigidly connected to the machine frame through the latch mechanism when stretching, and both the stretching head and the tailstock can move along the guide rails set on the foundation. The stretch leveler of this structure provided by the present invention can effectively absorb the impact energy when the material is broken, and can effectively avoid the impact on the main stretch oil cylinder and the equipment foundation, thereby improving the service life of the stretch leveler; The combined stretching oil cylinder enables the stretching head to move rapidly in empty space; the special jaw clamping form can ensure that the profile will not slip when stretched.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to a stretching and straightening machine for heavy-duty aluminum profiles. Background technique [0002] At present, domestic small and medium-sized aluminum profile offline stretching and straightening machines mostly adopt the center-loaded stretching method with no buffer and double cylinders inverted. When the material is broken, the impact energy is mainly absorbed by the main stretching cylinder; For straight machines, due to the relatively large impact energy when the material is cut off, simply absorbing the impact energy by the main stretching cylinder will bring great impact to the equipment and hydraulic system, seriously affecting the service life of the equipment. At the same time, due to the heavy moving parts of the heavy-duty aluminum profile stretching leveler and the large cross-sectional size of the stretched aluminum profile, a new st...
