Description

Technical Field

[0001] This utility model relates to the field of PP honeycomb panel processing technology, specifically to a PP honeycomb panel stretching and forming equipment. Background Technology

[0002] PP honeycomb panels are made by firmly bonding two thinner panels to both sides of a thicker honeycomb core material. The cross-section has a honeycomb structure, hence the name honeycomb panel. When stretching and plasticizing PP honeycomb panels, they need to be heated. The main purpose of heating PP honeycomb panels is to soften them, making them easier to plastically deform during the stamping process.

[0003] Currently, heating PP honeycomb panels typically involves using a hot air gun or a hot air circulating oven to preheat the panels, or placing the panels on an electric heating plate to transfer heat and preheat the material.

[0004] Regardless of the method used, the PP honeycomb panel needs to be preheated and softened before being quickly placed into a mold and stamped. Because the PP honeycomb panel is heated and softened, it is very hot, and workers are easily burned during the process of placing it into the mold.

[0005] Therefore, this utility model designs a PP honeycomb panel stretching and forming equipment to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a PP honeycomb panel stretching and forming equipment to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a PP honeycomb panel stretching and forming equipment, comprising: a mold base, a lower mold mounted on one side of the top of the mold base, a heating insert mounted on the lower mold, an electric heating plate provided on the inner wall of the heating insert, an L-shaped bracket provided above the electric heating plate, an electric cylinder mounted on the top of the L-shaped bracket, an upper mold connected to the output end of the electric cylinder, a moving component for moving the L-shaped bracket provided on the mold base, a cooling component provided on one side of the mold base, and a PLC controller provided at one end of the mold base.

[0008] Preferably, the lower mold and the heating plate are connected by a heat insulation plate, which serves to insulate the heat.

[0009] Preferably, the moving component includes a long slot, which is formed at one end of the top of the mold base. A screw is rotatably installed in the long slot. The outer wall of the screw and the bottom of the L-shaped bracket are slidably connected by threads. The L-shaped bracket and the long slot are slidably installed. When placing and picking up the PP honeycomb panel, the screw rotates, driving the L-shaped bracket to move, so that the upper mold is away from directly above the lower mold, which protects the worker's arm.

[0010] Preferably, two rollers that are tactilely connected to the mold base are installed at both ends of the L-shaped bracket. When the screw rotates, it drives the L-shaped bracket to move. The L-shaped bracket drives the rollers to roll on the mold base, which can reduce the friction of the L-shaped bracket movement.

[0011] Preferably, the cooling component includes a mounting frame, which is installed on the side of the mold base located on the lower mold. An electric push rod is installed on the mounting frame, and a fan is provided at the output end of the electric push rod. After molding, the electric push rod drives the fan to move above the PP honeycomb panel and blows air to cool the PP honeycomb panel, preventing burns when it is removed.

[0012] Preferably, the top of the upper mold is equipped with a slide rod that is slidably connected to the L-shaped bracket. When the upper mold is raised or lowered, the slide rod slides on the L-shaped bracket, which can improve the stability of the upper mold.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model directly places the unheated PP honeycomb panel into the heating insert on the lower mold. The electric heating plate is energized to heat and soften the PP honeycomb panel. After softening, the electric cylinder drives the lower mold to press down and plasticize the PP honeycomb panel. By heating directly in the lower mold, there is no need for workers to preheat the PP honeycomb panel before placing it in, thus avoiding the situation where workers are burned.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 An embodiment of this utility model provides a PP honeycomb panel stretching and forming equipment, comprising: a mold base 1, a lower mold 2 installed on one side of the top of the mold base 1, a heating insert 4 installed on the lower mold 2, an electric heating plate 5 provided on the inner wall of the heating insert 4, an L-shaped bracket 6 provided above the electric heating plate 5, an electric cylinder 7 installed on the top of the L-shaped bracket 6, an upper mold 8 connected to the output end of the electric cylinder 7, a moving component 9 for moving the L-shaped bracket 6 provided on the mold base 1, a cooling component 10 provided on one side of the mold base 1, and a PLC controller provided at one end of the mold base 1.

[0021] Please see Figure 1-3 In this embodiment, the lower mold 2 and the heating plate 5 are connected by a heat insulation plate 3.

[0022] Please see Figure 1-3 In this embodiment: the moving component 9 includes a long slot 901, which is opened at one end of the top of the mold base 1. A screw 902 is rotatably installed in the long slot 901. The outer side wall of the screw 902 and the bottom of the L-shaped bracket 6 are slidably connected by threads. The L-shaped bracket 6 and the long slot 901 are slidably installed. An installation groove is opened on the mold base 1. One side of the screw 902 passes through the installation groove and is connected to the output end of the servo motor.

[0023] Please see Figure 1-3 In this embodiment: two rollers 903 that are tactilely connected to the mold base 1 are installed at both ends of the L-shaped bracket 6.

[0024] Please see Figure 1-3 In this embodiment: the cooling component 10 includes a mounting bracket 101, which is mounted on the side of the mold base 1 located on the lower mold 2. An electric push rod 102 is mounted on the mounting bracket 101, and a fan 103 is provided at the output end of the electric push rod 102.

[0025] Please see Figure 1-3 In this embodiment: the top of the upper mold 8 is equipped with a slide rod that is slidably connected to the L-shaped bracket 6.

[0026] Working principle: The PP honeycomb panel is placed in the heating insert 4, and the electric heating plate 5 is energized to heat and soften the PP honeycomb panel. Heating directly inside the lower mold 2 is more convenient than heating externally and then removing it from the lower mold 2. The softened panel is easier to shape. After softening for a certain period of time, the electric cylinder 7 drives the upper mold 8 to press down, thus stamping the softened PP honeycomb panel. When removing the PP honeycomb panel after stamping and when placing the PP honeycomb panel before stamping, the screw 902 rotates and drives the L-shaped bracket 6 to move, moving the upper mold 8 away from directly above the lower mold 2, improving the safety of the workers when handling and placing the panel. Before removal, the electric push rod 102 drives the fan 103 to move above the heating insert 4, and the roller 903 blows air to cool the PP honeycomb panel, preventing workers from being burned when handling it.
