Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum alloy workpiece processing, and in particular relates to a demoulding mechanism used for bending and forming aluminum alloy workpieces. Background Art

[0002] The titanium plating process for aluminum profiles belongs to the coating technology. It adds pre-plating and electroplating process steps on the basis of the conventional titanium plating process. The aluminum profile process is to place the activated plated parts in an aqueous solution of salt and hydrochloric acid for chemical treatment. In the process of processing aluminum profiles, especially the processing of strip aluminum profile workpieces, the existing bending methods are divided into manual bending and hydraulic bending. This method is not convenient for precise adjustment of the bending angle of the aluminum profile, resulting in low processing accuracy of the device and unable to meet the producer's multi-angle bending needs.

[0003] To this end, an aluminum profile mold bending mechanism with a bulletin number of "CN212285429U" includes a base, a working groove is opened inside the base, a movable groove is opened through the upper surface of the working groove, and a plurality of first limit rods and second limit rods are respectively provided at the two side edges of the movable groove, and the plurality of first limit rods and second limit rods are symmetrically arranged, a slider is cooperated and connected in the movable groove, a fixed rod is provided on the upper surface of the slider, and a bending pressure wheel is sleeved on the outer wall of the fixed rod. When in use, the strip aluminum profile to be bent is placed between the first limit wheel and the second limit wheel, the driving part is started, and the slider is driven to move, so that the bending pressure wheel moves and contacts with the aluminum profile.

[0004] For the above-mentioned aluminum profile mold bending mechanism, although the bending angle of the aluminum profile can be freely adjusted by controlling the moving distance of the slider, so that the user can freely bend the aluminum profile at multiple angles according to actual needs, it still has the following obvious defects during use: the above-mentioned mold is used to bend the aluminum alloy by directly sliding horizontally and applying pressure to the bending part during the bending process, but the limiting wheel is fixed on the base so that the workpiece with elasticity of the bending is tensioned outward on the inner side of the limiting wheel, so that when the workpiece is taken out, the tensioning force makes the workpiece stuck in the base, which makes it difficult and laborious to take out, thereby reducing the efficiency of the aluminum alloy bending processing, and when taking out, the outward elastic force at both ends of the aluminum alloy workpiece may cause personal injury.

This item can clamp the aluminum alloy workpiece at the bending position by pushing the clamping limiting wheel through the limiting cylinder member during the bending process, thereby ensuring the stability of the aluminum alloy workpiece during the bending process.

[0008] Preferably, the top end of the vertical plate extends to the outside of the upper end of the strip groove, and the workpiece bending push wheel and the clamping limit wheel on the inner side of the vertical plate are arranged at the center position of the end face of the workbench.

[0009] Preferably, a limit push adjustment cylinder is provided at one end of the workpiece limit roller component, and the limit push adjustment cylinder is installed at the front and rear ends on the left side of the workbench end surface. This item can adjust the spacing of the workpiece limit roller component through the limit push adjustment cylinder according to the spacing of the bending inner diameter of the aluminum alloy workpiece, so as to achieve the bending angle of different inner diameter spacings at the bending point of the aluminum alloy workpiece.

[0010] Preferably, the workpiece bending pushing roller component includes pushing rollers that are laterally symmetrically arranged, and a bending adjustment cylinder for longitudinally adjusting the pushing roller is installed on one side of the workpiece bending pushing roller component. This item can limit and tighten the two ends of the bent aluminum alloy workpiece through the pushing roller, which can play a role in bending and shaping the aluminum alloy workpiece, and is beneficial to the bending and forming of the aluminum alloy workpiece.

[0011] Preferably, the surface of the workpiece conveyor belt arranged on the workpiece conveying roller for transmission is arranged as an anti-slip layer, and the workpiece conveyor belt is kept in a horizontal state with the surface of the workbench before the aluminum alloy workpiece is bent. This has the effect of automatically conveying the aluminum alloy workpiece to one side of the workbench for easy picking up through the cooperation of the workpiece conveying roller and the workpiece conveyor belt after the aluminum alloy workpiece is lifted up, demolded and suspended in the air.

[0012] The technical effects and advantages of the utility model are as follows: the demoulding mechanism for bending and forming aluminum alloy workpieces first places the aluminum alloy workpiece horizontally between the workpiece bending push wheel and the clamping limit wheel, and then pushes the clamping limit wheel to clamp the aluminum alloy workpiece at the bending position through the limit cylinder, thereby ensuring that the aluminum alloy workpiece maintains stability during bending. At this time, the hydraulic cylinder pushes the movable limit bar block to move in the bar groove, so that the workpiece bending push wheel drives the clamped aluminum alloy workpiece to move forward for bending. The workpiece limiting roller component is pushed to tighten the two ends of the aluminum alloy. As the aluminum alloy workpiece gradually moves and is bent, the workpiece limiting roller component follows the limiting pushing and adjusting cylinder to limit and tighten the two ends of the aluminum alloy workpiece. Subsequently, the bending adjusting cylinder is set to push the workpiece bending roller component to tighten and fix the middle part of the gradually bent aluminum alloy bending part to ensure the shaping of the aluminum alloy workpiece after bending, and can bend the aluminum alloy workpiece into aluminum alloy workpieces with different inner diameters and lengths, thereby being able to process aluminum alloy workpieces with different bending angles.

[0013] After the aluminum alloy workpiece is bent and formed, the limit pushing and adjusting cylinder and the bending adjusting cylinder drive the workpiece limit roller component and the workpiece bending pushing roller component to move and loosen the tightness of the aluminum alloy workpiece to remove the outward elastic tension. Then, the horizontal plate of the lifting cylinder moves upward to make the workpiece conveying roller move upward with it, and the workpiece conveying roller drives the upper part of the bent aluminum alloy workpiece through the workpiece conveyor belt. At the same time, the workpiece conveying roller drives the workpiece conveyor belt to rotate to drive the aluminum alloy workpiece to one side and move it out of the workbench for the staff to take it, thereby realizing the effect of automatic ejection and demoulding of the bent aluminum alloy workpiece, and there will be no problem that the elastic tension generated after the aluminum alloy workpiece is bent cannot be removed and the elastic force of taking out the aluminum alloy workpiece with elastic tension hits the staff and causes injuries.
