Description

Technical Field

[0001] This invention relates to a honeycomb core stretching device, and more particularly to a honeycomb core stretching device for honeycomb panel production. Background Technology

[0002] Aluminum honeycomb panels consist of an aluminum face panel, an aluminum honeycomb core, and an aluminum back panel. The aluminum honeycomb core offers advantages such as waterproofing, moisture resistance, no release of harmful gases, high specific strength per unit mass, high specific stiffness, and resistance to deformation. During the production process, an aluminum honeycomb core stretching machine is used to stretch the originally bonded aluminum honeycomb core semi-finished products into a mesh-like honeycomb panel.

[0003] An aluminum honeycomb core stretching machine (CN109175056B) is disclosed, comprising a frame, a fixed support, a sliding support, and a drive unit. Both the fixed and sliding supports are equipped with a chuck mechanism, which includes multiple chucks and a ratchet shaft. Each chuck comprises a chuck bracket, an inner ratchet, a crank, a connecting rod, and a pin. The chuck bracket is slidably mounted on the fixed or sliding support, and the inner ratchet is mounted on the chuck bracket. The ratchet shaft is rotatably mounted on the fixed or sliding support, and chucks are continuously arranged along the axial direction of the ratchet shaft. This invention, through the chuck mechanism, allows pins to be inserted one by one into the blank according to its size and appropriate insertion position, without interference between pins. All pins in the same chuck mechanism can be removed via a single ratchet shaft.

[0004] However, in actual use, this invention requires manual operation and can no longer meet the requirements of automation. Summary of the Invention

[0005] This invention provides a honeycomb core stretching device for honeycomb panel production, which solves the problem that existing technologies cannot meet automation requirements.

[0006] The above-mentioned technical problems of the present invention are mainly solved by the following technical solution: a honeycomb core stretching device for honeycomb panel production, comprising a frame, a fixed frame, a movable frame, and a servo component. The movable frame is slidably mounted on the frame, and the servo component is used to drive the movable frame to reciprocate. Both the fixed frame and the movable frame are provided with pin assemblies. Each pin assembly consists of two horizontally parallel guide rods fixed to the fixed frame or the movable frame, a central reference seat, several sliding seats, a pneumatic ejector pin, and a pneumatic resetter. The central reference seat is simultaneously fixed to the two guide rods, and the several sliding seats are slidably disposed on the two guide rods and distributed on both sides of the central reference seat. The pneumatic ejector pins are vertically mounted on both the reference base and the sliding base. The center positions of all the pneumatic ejector pins are located on one side of the same guide rod and are evenly distributed. The pneumatic resetter is located between any two adjacent sliding bases and between the sliding base and the central reference base. The pneumatic resetter consists of a first cylinder, an adjusting cylinder, and an elastic pressing component. The first cylinder is horizontally fixed on the sliding base or the central reference base. The adjusting cylinder is screwed onto the telescopic rod of the first cylinder. The elastic pressing component is located on the sliding base or the central reference base and can press the adjusting cylinder onto its own sliding base or the central reference base. Both the pneumatic resetter and the pneumatic ejector pins are connected to the pneumatic system.

[0007] The actions of the fixed frame, moving frame, and servo component in this invention are consistent with existing solutions and will not be described in detail here. The pin assembly in this invention is used to control the insertion of the "pins" into the honeycomb core in the mating state. Since the honeycomb core lengthens but its width shortens during the stretching process, the spacing between adjacent "pins" will gradually narrow. Therefore, during the stretching process, the spacing between the "pins" on the pin assembly needs to be adaptively narrowed, and the "pins" need to automatically reset before stretching so that the position of the "pins" inserted each time is fixed. Therefore, this invention uses a central reference seat fixed at the center of the guide rod as a reference. Sliding seats located on both sides of the central reference seat are connected in series with it via pneumatic resetters. The longest extension length of each pneumatic resetter is equal. When the invention is about to insert a "pin" into the honeycomb core, the pneumatic ejector is in a retracted state under the control of the pneumatic system, and the pneumatic resetter is in a fully extended state under the control of the pneumatic system. Therefore, all sliding seats are reset to the preset position. Then, under the control of the pneumatic system, the pneumatic ejector extends and inserts into the honeycomb core. The moving frame begins to stretch the honeycomb core to one side. Simultaneously, under the control of the pneumatic system, the piston chamber inside the pneumatic resetter is connected to the atmosphere and is under normal pressure, allowing its length to be freely compressed, thus satisfying the characteristic of narrowing width during the stretching process of the honeycomb core. The function of the elastic pressing component is to ensure that the adjusting cylinder and the sliding seat or central reference seat remain in contact, and to allow a certain displacement of the contact area. This effectively avoids the problem of the pneumatic resetter jamming due to assembly accuracy issues.

[0008] The present invention can change the maximum length of the pneumatic resetter when fully extended by rotating the adjusting cylinder, so that the present invention can be adapted to various types of honeycomb panels.

[0009] Therefore, the present invention has the following characteristics compared with the prior art: 1. The present invention can autonomously complete the reset of the sliding seat, so there is no need to manually adjust the initial position of the pneumatic pin, and the pneumatic pin can autonomously complete the "pin" insertion and removal action under the control of the pneumatic system; 2. The present invention can change the maximum length of the pneumatic resetter when fully extended by rotating the adjusting cylinder, so that the present invention can be adapted to various types of honeycomb panels.

[0014] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0016] Example 1: See Figure 1 , Figure 2 and Figure 3 A honeycomb core stretching device for honeycomb panel production includes a frame 10, a fixed frame 20, a movable frame 30, and a servo assembly. The movable frame is slidably mounted on the frame. The servo assembly drives the movable frame to reciprocate. Both the fixed frame and the movable frame are equipped with pin assemblies 100. Each pin assembly consists of two horizontally parallel guide rods 110 fixed to the fixed frame or the movable frame, a central reference seat 120, several sliding seats 130, pneumatic ejector pins 140, and a pneumatic resetter 150. The central reference seat is simultaneously fixed to the two guide rods. The several sliding seats are slidably mounted on the two guide rods and distributed on both sides of the central reference seat. Pneumatic ejector pins are vertically mounted on both the central reference seat and the sliding seats. Some pneumatic ejectors are all centered on one side of the same guide rod and are evenly spaced; the pneumatic resetter is located between any two adjacent sliding seats and between the sliding seat and the central reference seat. The pneumatic resetter consists of a first cylinder 151, an adjusting cylinder 152 and an elastic pressing component 153. The first cylinder is horizontally fixed on the sliding seat or the central reference seat. The adjusting cylinder is screwed onto the telescopic rod of the first cylinder. The elastic pressing component is located on the sliding seat or the central reference seat and can press the adjusting cylinder onto the sliding seat or the central reference seat on which it is located. The pneumatic resetter and the pneumatic ejector are both connected to the pneumatic system. The second cylinder is only connected to the pneumatic system at the air injection port at the end away from its telescopic rod.

[0017] See Figure 3 The pneumatic ejector consists of an ejector 141 and a second cylinder 142. The second cylinder is vertically fixed on the sliding seat or the central reference seat. The extension rod of the second cylinder is provided with an ejector fixing plate 143. The ejector is vertically fixed on the ejector fixing plate. The sliding seat and the central reference seat are also provided with ejector guide plates 144. The ejector passes through the ejector guide plates.

[0018] See Figure 4The outer end of the regulating cylinder is provided with an abutment part 154, which is made of wear-resistant alloy and can be fixed to the regulating cylinder by welding. An overlapping piece 155 extends outward from the side wall. The elastic pressing part is an elastic piece with a fixed end at one end and a pressing end abutting on the overlapping piece at the other end.

[0019] The actions of the fixed frame, moving frame, and servo component in this embodiment are consistent with the existing solutions and will not be described again here. The pin assembly in this embodiment is used to control the insertion of the "pins" into the honeycomb core in the mating state. Since the honeycomb core lengthens but its width shortens during the stretching process, the spacing between adjacent "pins" will gradually narrow. Therefore, the spacing between the "pins" on the pin assembly needs to be adaptively narrowed during the stretching process, and the "pins" need to be automatically reset before stretching so that the position of the "pins" inserted each time is fixed. Therefore, this embodiment uses a central reference seat fixed at the center of the guide rod as the reference. Sliding seats on both sides of the central reference seat are connected in series with it via pneumatic resetters. The longest extension length of each pneumatic resetter is equal. When this embodiment prepares to insert the honeycomb core as a "pin," the pneumatic ejector pin is in a retracted state under the control of the pneumatic system, and the pneumatic resetter is in a fully extended state under the control of the pneumatic system. Therefore, all sliding seats are reset to the preset position. Then, under the control of the pneumatic system, the pneumatic ejector pin extends and inserts into the honeycomb core. The moving frame begins to stretch the honeycomb core to one side. Simultaneously, under the control of the pneumatic system, the piston chamber inside the pneumatic resetter is connected to the atmosphere and is under normal pressure, allowing its length to be freely compressed, thus satisfying the characteristic of narrowing width during the stretching process of the honeycomb core. The function of the elastic pressing component is to ensure that the adjusting cylinder and the sliding seat or central reference seat remain in contact, and to allow a certain displacement of the contact area. This effectively avoids the problem of the pneumatic resetter getting stuck due to assembly accuracy issues.

[0020] This embodiment allows the maximum length of the pneumatic resetter to fully extend to be changed by rotating the adjusting cylinder, making it adaptable to various types of honeycomb panels.

[0021] It will be apparent to those skilled in the art that the present invention can be modified in various ways, and such modifications are not considered to depart from the scope of the invention. All such modifications that are obvious to those skilled in the art are included within the scope of the claims.
