An automatic clamping hydraulic ramming machine for aluminum processing

Abstract

The invention relates to the technical field of aluminum material processing equipment, and discloses a hydraulic angle ram machine with automatic material clamping for aluminum material processing. A compression cylinder is fixedly installed on the upper part of the front, and a positioning block is fixedly connected to the bottom of the compression cylinder. Through the setting of the negative pressure tuyere and the lower pressure plate, after the assembly is completed, the electromagnet is powered off, and the lower pressure plate moves downward under the action of the pressure spring to compress the aluminum material, which not only replaces the manual fixing of the aluminum material, Moreover, it can prevent the aluminum from being squeezed and lifted, greatly improving the accuracy of the assembly, thereby improving the quality of the collision angle, and the suction of the negative pressure air port is smaller than the deformation of the aluminum, so that when the hydraulic cylinder continues to expand and contract, the supporting slider can Adsorbing and sliding on the lower surface of the aluminum material not only does not affect the butt joint pressure of the aluminum material, but also does not cause the aluminum material to be squeezed and deformed by the hydraulic cylinder, resulting in damage to the aluminum material.

Description

technical field [0001] The invention relates to the technical field of aluminum material processing equipment, in particular to a hydraulic angle ram machine with automatic material clamping for aluminum material processing. Background technique [0002] The corner hitting machine, also known as the corner forming machine, is a special equipment for the production of high-grade broken bridge aluminum alloy doors and windows. It is suitable for the 90-degree angle connection of the corner code structure aluminum doors and windows. Corner group machine, four-head corner group machine, the corner group slide plate is pushed by the corner group oil cylinder, the corner group slide plate moves forward, and the left and right punching shafts are pushed at the same time, and the corner group knife on the punching riveting shaft realizes the 90-degree angle connection of aluminum doors and windows .

Problems solved by technology

[0003] However, the existing hydraulic corner rams still have the following problems in the actual use process: when most traditional corner rams work, the aluminum door and window materials need to be manually combined, and then placed on the positioning block of the corner ram, fixed by After the device is fixed, it is connected by a corner knife, and during the working process, the staff needs to press the aluminum material, which is not only time-consuming and laborious, but also it is difficult to achieve accurate assembly of the aluminum material by manual pressing; In the process of pairing, the jacking hydraulic cylinders are set on both sides, and the aluminum materials are pushed by the jacking hydraulic cylinders to realize the pairing of the aluminum materials on both sides at the angle between the positioning blocks. However, for aluminum materials of different lengths, this method It is difficult to grasp the stroke and action time of the jacking hydraulic cylinder, so that the movement distance of the aluminum material is not well controlled, often resulting in over-fitting or incomplete matching. Extruded, lifted or even deformed by extrusion, which seriously affects the assembly effect of positioning accuracy, thereby affecting the quality of the corner assembly. effect
