Description

Technical Field

[0001] This utility model relates to the field of sheet metal forming and processing technology, and in particular to an automatic heating forming and bending fixture. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] In the processing of plastics, composite materials, or thin metal sheets, it is often necessary to soften the material by heating before bending it to obtain the desired shape. Existing technologies generally adopt a sequential processing mode: the material is first placed in a separate heating device and heated to the forming temperature, and then manually removed and transferred to a bending machine or forming mold for bending operations.

[0004] However, the aforementioned traditional processes have significant technical defects and shortcomings: 1. Dispersed processes and low production efficiency: The heating and bending processes are separated, which involves material transfer between equipment, resulting in a long production process, difficulty in achieving continuous operation, and low overall processing efficiency; 2. High degree of manual intervention and poor safety: The material transfer process relies on manual operation, which is not only labor-intensive, but also makes it difficult to guarantee positioning accuracy; high-temperature materials can easily cause burns to operators, and scratches, bumps and other appearance defects are easily generated during the handling process; 3. Serious energy waste: The material loses heat quickly during the transfer process. In order to ensure that the forming temperature is still reached during bending, the material needs to be overheated during the heating stage, resulting in additional energy consumption and low energy utilization. 4. Unstable molding quality: The material temperature continues to drop during the transfer process, resulting in uneven actual temperature during bending. This affects the softening degree and fluidity of the material, causing deviations in bending angle, inconsistent springback, and fluctuations in molding accuracy, making it difficult to guarantee product yield. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings by providing an automatic heating and forming bending fixture, thereby improving production efficiency and reducing energy consumption.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: an automatic heating and forming bending fixture, comprising: The lower mold base plate is provided with a cavity for placing the material feeding component; The upper mold base plate is composed of two slide rails disposed on the top of the lower mold base plate and located on both sides of the cavity, and a platform slidably disposed on the slide rails. The distance between the platform and the lower mold base plate is not less than the height of the workpiece. The first pushing component is disposed on the lower mold base plate and is used to horizontally push the upper mold base plate to move towards or away from the cavity. At least two bending assemblies are respectively disposed on the lower mold base plate and the upper mold base plate. The bending assembly consists of a bending head, a heating rod disposed inside the bending head, and a second pushing component that pushes the bending head to move closer to or further away from the cavity.

[0007] Furthermore, the bending pressure head consists of a mounting base disposed at the driving end of the second pushing component and a pressure head detachably disposed on the mounting base, and the heating rod is disposed inside the mounting base.

[0008] Furthermore, it also includes a pressing mechanism disposed on the lower mold base plate or the upper mold base plate, the pressing mechanism consisting of a pressing head and a third pushing component that pushes the pressing head to move closer to or further away from the cavity.

[0009] Furthermore, it also includes an ejector mechanism disposed on the lower mold base plate, the ejector mechanism consisting of an ejector head and a fourth pushing component that pushes the ejector head to move closer to or further away from the cavity.

[0010] Furthermore, the ejector head is provided with an air passage, and the ejector mechanism also includes a vacuum system connected to the air passage. The vacuum system is used to draw air so that the ejector head can adsorb the material inside the cavity.

[0011] Furthermore, it also includes at least one heat insulation component, which includes a C-shaped frame fixedly mounted on the lower mold base plate. The side of the C-shaped frame closest to the cavity is the open side. Two cover plates are rotatably mounted on the open side of the C-shaped frame via a torsion spring. When the torsion spring is in its natural state, the two cover plates are not located within the moving area of ​​the corresponding bending head. A gear is provided at the pivot of the cover plate. A rack that can mesh with the gear is provided on the upper mold base plate. When the bending head is located within the corresponding C-shaped frame and moves away from the cavity, the rack meshes with the gear and drives the cover plate to rotate and seal the open side.

[0012] The beneficial effects of this utility model are reflected in: This invention integrates heating and bending processes, eliminating material transfer time, reducing the risk of burns, significantly shortening the production cycle, and significantly improving production efficiency. It adopts a built-in heating rod to heat the material directly to the area to be bent, which has high thermal efficiency, rapid heating, and no need for transfer operations, effectively reducing heat loss and achieving the goal of energy saving and consumption reduction.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figure 1-5 This utility model discloses an automatic heating and forming bending fixture, comprising: The lower mold base plate 1 has a cavity for placing the material feeder. The upper mold base plate 2 is composed of two slide rails disposed on the top of the lower mold base plate 1 and located on both sides of the cavity, and a platform slidably disposed on the slide rails. The distance between the platform and the lower mold base plate 1 is not less than the height of the part. The first pushing component 3 is disposed on the lower mold base plate 1 and is used to horizontally push the upper mold base plate 2 to move towards or away from the cavity. At least two bending components 4 are respectively disposed on the lower mold base plate 1 and the upper mold base plate 2. The bending component 4 consists of a bending head 41, a heating rod 42 disposed in the bending head 41, and a second pushing component 43 that pushes the bending head 41 to move closer to or further away from the cavity.

[0017] This invention integrates heating and bending processes, eliminating material transfer time, reducing the risk of burns, significantly shortening the production cycle, and significantly improving production efficiency. It adopts a built-in heating rod to heat the material directly to the area to be bent, which has high thermal efficiency, rapid heating, and no need for transfer operations, effectively reducing heat loss and achieving the goal of energy saving and consumption reduction.

[0018] In one embodiment, the bending head 41 consists of a mounting base disposed on the driving end of the second pushing member 43 and a head detachably disposed on the mounting base, and the heating rod 42 is disposed inside the mounting base.

[0019] This design breaks down the bending head 41 into a "mounting base + detachable head". The mounting base serves as the carrier of the heating rod 42 and the connection end of the second pushing component 43, realizing the transfer of power and heat. The detachable head design allows for quick adaptation of head of different specifications or shapes to the mounting base. When replacing, there is no need to disassemble the entire bending assembly; only the head needs to be disassembled and reassembled. Combined with the structure of the heating rod 42 integrated into the mounting base, it avoids repeated debugging of the heating system after changing models, greatly improving the production adaptability of multi-specification products.

[0020] It should be noted that, in order to improve the accuracy of the heating temperature of each pressure head, a thermocouple for monitoring the pressure head temperature is installed on the mounting base.

[0021] In one embodiment, a pressing mechanism is further provided on the lower mold base plate 1 or the upper mold base plate 2. The pressing mechanism consists of a pressing head and a third pushing component that pushes the pressing head to move closer to or further away from the cavity.

[0022] With this design, the third pushing component drives the pressing head to move towards the cavity side, which can press and fix the material after it enters the cavity and before bending, replacing the traditional positioning method of manual holding or simple tooling, eliminating positioning deviation caused by manual operation. At the same time, since the movement of the pressing head is independently controlled by the third pushing component, it can be adjusted according to the thickness of the material, making it more compatible.

[0023] In practice, a silicone pad is provided on the side of the pressing head that contacts the material to reduce damage to the material during the pressing process.

[0024] In one embodiment, the system further includes an ejector mechanism disposed on the lower mold base plate 1. The ejector mechanism consists of an ejector head and a fourth pushing component that pushes the ejector head to move closer to or further away from the cavity.

[0025] This design allows the fourth pushing component to drive the ejector head to move towards the cavity side after bending and forming, lifting the material from the cavity, replacing the manual or tool-based prying method, and avoiding scratches on the surface of the material caused by manual operation.

[0026] It should be noted that the first pushing component 3, the second pushing component 43, the third pushing component and the fourth pushing component are preferably pneumatic telescopic components in the prior art.

[0027] In one embodiment, the ejector head is provided with an air passage, and the ejector mechanism also includes a vacuum system connected to the air passage. The vacuum system is used to draw air so that the ejector head can adsorb the material in the cavity.

[0028] With this design, after the material is placed into the cavity, the vacuum system draws air through the air passage, causing the top material pressure head to generate negative pressure to adsorb the material. This, together with the pressing mechanism, forms a "two-way fixation" that further improves the stability of the material positioning.

[0029] It should be noted that vacuum systems are common knowledge in this field, so their specific structural composition and working principle will not be elaborated on further in this article.

[0030] In one embodiment, at least one heat insulation component 5 is also included. The heat insulation component 5 includes a C-shaped frame 51 fixedly disposed on the lower mold base plate 1. The side of the C-shaped frame 51 closest to the cavity is the open side. Two cover plates 52 are rotatably disposed on the open side of the C-shaped frame 51 by a torsion spring. When the torsion spring is in its natural state, the two cover plates 52 are not located in the moving area of ​​the corresponding bending head 41. A gear 53 is disposed at the pivot of the cover plate 52. A rack 54 that can mesh with the gear 53 is disposed on the upper mold base plate 2. When the bending head 41 is located in the corresponding C-shaped frame 51 and moves away from the cavity, the rack 54 meshes with the gear 53 and drives the cover plate 52 to rotate and seal the open side.

[0031] This design allows the upper mold base plate 2 to drive the bending head 41 into the C-shaped frame 51 for heat preservation after the material is bent. Through the cooperation of the cover plate 52, rack 54 and gear 53, a semi-enclosed heat preservation space is formed after the bending head 41 is fully moved in, reducing the heat diffusion to the surrounding environment and thus reducing the subsequent heating time. When the bending head 41 is moved out, the rack 54 will first push the gear 53 to rotate, causing the cover plate 52 to rotate and open, without affecting the normal movement of the bending head 41.

[0032] In practice, insulation boards can be added to both the C-shaped frame 51 and the cover plate 52 to further improve insulation performance.

[0033] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0034] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0035] Additionally, "multiple" refers to two or more.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
