Description

Technical Field

[0001] The utility model relates to the field of honeycomb core stretching, and in particular to an aluminum honeycomb core stretching blanking structure. Background Art

[0002] In the production and manufacturing process of honeycomb panels, the honeycomb core needs to be stretched. The stretching method can be manual stretching, which is a test of the level of the stretching personnel and requires a long period of training. However, due to the different techniques of each person, there will still be uneven force and uneven stretched holes, resulting in unguaranteed quality and low efficiency. Another method is to stretch the honeycomb core through a stretching machine, and position the honeycomb aluminum strips through the positioning clamping structure and the movable clamping structure, and then stretch them by moving the movable clamping structure. For example, the Chinese patent with application number CN202120313109.6 provides a solution called an aluminum honeycomb core stretching machine, which replaces manual stretching, effectively improves the stretching quality, and improves the stretching efficiency. However, this solution After the stretching is completed, the stretched honeycomb core will fall directly onto the frame, and the operator needs to remove it from the frame before performing the next stretching operation. Since the movable clamping structure and the positioning clamping structure used for stretching are respectively arranged at the left and right ends of the frame, the operator needs to move to the front or rear end of the frame to take out the stretched honeycomb core. After taking out the material, the operator returns to the end of the frame where the positioning clamping structure is installed to load the material. This will cause the operator to move back and forth between the loading and unloading points, and the stretching speed is fast. In the case of long-term operation, this increases the labor intensity of the operator, or it is necessary to arrange staff at both the loading and unloading points, which leads to an increase in labor costs. At the same time, the clamping effect of the positioning clamping structure and the movable clamping structure in the prior art is not good.

[0003] Therefore, those skilled in the art are committed to providing a honeycomb core stretching blanking structure that can effectively solve the above technical problems. Utility Model Content

[0043] The optimal working principle of this utility model is as follows:

[0044] The honeycomb aluminum strip to be stretched is positioned by the positioning clamping unit 5 and the movable clamping unit 6. Specifically, the positioning cylinder 11 drives the needle 13 to move, and the needle 13 moves downward while being guided by the slide rail 26. As the needle 13 moves downward, the honeycomb aluminum strip is positioned, and then the sliding seat 8 is moved. The movement method can adopt any structure in the prior art that can drive the sliding seat 8 to move, such as a gear rack structure or a screw nut structure, and then it can be driven by a motor. Since they are all prior art structures, they will not be repeated here. The stretching is completed by the sliding seat 8. As a further preference, in order to improve the applicability of the utility model, the spacing between each pin unit 9 can be adjusted according to the size of the honeycomb aluminum strip to be stretched before stretching. The specific adjustment method is, By loosening the locking nut 33, then adjusting the position of the pin unit 9, and tightening the locking nut 33 after the adjustment is completed to position it, after the stretching is completed, the needle head 13 returns to its position and is no longer positioned. The stretched honeycomb core falls down onto the first receiving plate 18. At this time, the operator does not need to remove the honeycomb core on the first receiving plate 18 and can continue to stretch the next honeycomb aluminum strip. When the honeycomb cores accumulated on the first receiving plate 18 reach a certain number, the first receiving plate 18 is moved to the right, and then the second receiving plate 19 is moved to the bottom of the positioning frame 2, so as to continue to receive the material through the second receiving plate 19, and the first receiving plate 18 equipped with the honeycomb core is moved out from under the positioning frame 2, which is not only more convenient for the operator to take the material, but also will not affect the second receiving plate 19 receiving the material.

It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
