Description

Technical Field

[0001] This utility model relates to the field of processing technology of thermoplastic composite materials, and in particular to a bending mechanism for thermoplastic composite materials. Background Technology

[0002] Thermoplastic composites (also known as thermoplastic plastics) are a class of linear polymer materials that soften upon heating and harden upon cooling, and this process can be repeated. Therefore, for bending thermoplastic composite products, this characteristic of thermoplastic composites can be used to soften the material at controlled temperature before shaping and bending.

[0003] Currently, there are different methods for heating and shaping thermoplastic composite products, including localized heating, overall heating, and spot heating. Different methods are used for different plasticity requirements. For bending of tubular, strip, or other similarly shaped thermoplastic composite products, localized heating is the most suitable. Localized heating generally includes localized heating with heating wires or hot air guns. After softening the product by heating the localized area at the bend, the thermoplastic product is placed in a mold for bending and shaping.

[0004] However, this process demands a high level of experience and skill from the operators. If the thermoplastic product is heated too softly, it can easily collapse and deform before being placed into the mold. Conversely, if the thermoplastic product is not heated enough, it may fail to bend properly. Furthermore, after softening, the operator must quickly and accurately insert the thermoplastic product into the mold, and then immediately close the mold. The entire process is quite tedious and demands significant skill from the operator, and is prone to various accidents that could lead to undesirable outcomes. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a bending mechanism for thermoplastic composite products, so as to solve the technical problem of the cumbersome and difficult process of first heating the thermoplastic product locally and then sending it into the mold for plastic deformation in the prior art.

[0006] To achieve the above objectives, this utility model provides a bending mechanism for thermoplastic composite materials, including a main base for bending, and the bending mechanism further includes:

[0007] A detachable mold-parting cover plate is attached to the main base. The upper surface of the main base and the lower surface of the mold-parting cover plate are each provided with a curved groove with a semi-circular cross-section, which together form a bending groove for thermoplastic products.

[0008] An air inlet pipe is fixedly connected to the main base. The bottom of the bending groove on the main base is provided with an air blowing port, which is connected to the air inlet pipe. The outer end of the air inlet pipe is connected to an external air source through an air heater.

[0009] Furthermore, the main base is provided with multiple modules, each module is provided with a separate mold cover plate, and each module is provided with a bending groove with a different bending shape.

[0010] Furthermore, a connecting column is fixedly connected to the main base, and a connecting groove is provided at the corresponding position of the mold parting cover plate. The connecting column is slidably connected in the connecting groove, and the outer diameter of the connecting column is the same as the inner diameter of the connecting groove.

[0011] Furthermore, an air extraction pipe is fixedly connected to the main base, and a through hole is provided at the top of the connecting column, which communicates with the air extraction pipe. The outer end of the air extraction pipe is connected to the air extraction machine.

[0012] Furthermore, the air intake pipe and the air extraction pipe are each provided with multiple pipes, and each module is connected to one air intake pipe and one air extraction pipe.

[0013] Furthermore, the front end of the main base is provided with an air valve control button for controlling the opening and closing of the air valves in the air inlet pipe and the air extraction pipe, and each module is provided with a corresponding air valve control button.

[0014] Furthermore, a guide slider is also provided in the bending groove, and the guide slider is movably connected in the bending groove.

[0015] Furthermore, the front end of the guide slider is provided with an end groove for connecting with the thermoplastic product, and a number of balls are rolledly connected to the outer side wall of the guide slider, the balls being rolledly connected to the inner wall of the bending groove.

[0016] The beneficial effects of this utility model are as follows: 1. A main base and a parting plate are provided, and bending grooves are provided on the main base and the parting plate. Hot air is blown out through air vents in the bending grooves to heat and soften the thermoplastic product, combining the local heating function and the bending plasticity of the mold into one. This replaces the operation of first heating and softening and then transferring to the mold for bending plasticity, greatly reducing the dependence on the worker's ability and experience, and reducing various adverse situations caused by accidents.

[0017] 2. Connecting columns are set to connect the main base and the parting plate. Air is drawn through the air extraction pipe and the top through hole of the connecting column, and negative pressure is generated in the corresponding connecting grooves on the connecting column and the parting plate to ensure that the parting plate is tightly connected to the main base, thereby ensuring the overall integrity of the bending groove.

[0018] 3. A guide slider is set to guide the thermoplastic product to move in. Several balls are rolled on the outer wall of the guide slider. The rolling of the balls allows the guide slider to smoothly insert the thermoplastic product into the bending groove, avoiding deformation of the softened thermoplastic product due to hitting the bending point of the bending groove.

[0019] 4. The main base has multiple modules, each with its own parting plate and a bending groove of different shapes. This allows for simultaneous bending of multiple thermoplastic products and meets the needs of various bending shapes. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0028] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0029] The first aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, the current bending operation of thermoplastic composite products involves locally heating and softening the bending area before placing the thermoplastic product into a mold for bending and plastic shaping. This process is quite cumbersome and requires a high level of experience and skill from the operators. Therefore, to reduce reliance on worker ability and experience, this design incorporates a main base 101 for bending and a detachable parting plate 104 connected to the main base 101.

[0030] A semi-circular curved groove is provided on the upper surface of the main base 101 and the lower surface of the mold parting cover 104, which together form a bending groove 105 for thermoplastic products. In addition, an air inlet pipe 102 is fixedly connected to the main base 101, and an air blowing port 107 is provided at the bottom of the bending groove 105 on the main base 101. The air blowing port 107 is connected to the air inlet pipe 102, and the outer end of the air inlet pipe 102 is connected to an external air source through an air heater.

[0031] By blowing hot air through the air outlet 107 within the bending groove 105, the thermoplastic product is heated and softened, combining localized heating and mold bending plasticity into one. This replaces the previous operation of first heating and softening before transferring the product to the mold for bending plasticity, greatly reducing reliance on worker skills and experience, and minimizing adverse situations caused by various accidents.

[0032] To ensure a tight connection between the main base 101 and the parting plate 104, a connecting post 108 is fixedly connected to the main base 101. A corresponding connecting groove is provided on the parting plate 104, and the connecting post 108 is slidably connected in the connecting groove. The outer diameter of the connecting post 108 is the same as the inner diameter of the connecting groove.

[0033] Then, an air extraction pipe 103 is fixedly connected to the main base 101. The top of the connecting column 108 is provided with a through hole, which communicates with the air extraction pipe 103. The outer end of the air extraction pipe 103 is connected to an air extraction machine. Air is extracted through the air extraction pipe 103 and the top through hole of the connecting column 108, generating negative pressure in the corresponding connecting grooves on the connecting column 108 and the parting plate 104. This ensures that the parting plate 104 is tightly connected to the main base 101, thereby ensuring the overall integrity of the bending groove 105.

[0034] The second aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 4 As shown, to make this solution more applicable, multiple modules are provided on the main base 101. Each module has a separate mold cover plate 104, and each module has a bending groove 105 with a different bending shape. Multiple air inlet pipes 102 and air extraction pipes 103 are provided, and each module is connected to one air inlet pipe 102 and one air extraction pipe 103 respectively.

[0035] A valve control button 106 is provided at the front end of the main base 101 to control the on / off state of the valves in the air inlet pipe 102 and the air extraction pipe 103, and each module is provided with a corresponding valve control button 106. Each module is provided with a bending groove 105 of different bending shapes. This not only enables bending operations on multiple thermoplastic products at the same time, but also meets the needs of various different bending shapes.

[0036] In addition, a guide slider 109 is provided within the bending groove 105, and the guide slider 109 is movably connected within the bending groove 105. The front end of the guide slider 109 is provided with an end groove 110 for connecting with thermoplastic products, and a plurality of balls 111 are rolledly connected to the outer side wall of the guide slider 109, and the balls 111 are rolledly connected to the inner wall of the bending groove 105.

[0037] A guide slider 109 is provided to guide the insertion and movement of the thermoplastic product. Several balls 111 are rolled on the outer wall of the guide slider 109. The rolling of the balls 111 allows the guide slider 109 to smoothly insert the thermoplastic product into the bending groove 105, preventing the softened thermoplastic product from being deformed by hitting the bending point of the bending groove 105.

[0038] In summary, this utility model provides a main base 101 and a parting plate 104, with bending grooves 105 on both. Hot air is blown out from air outlets 107 within the bending grooves 105 to heat and soften the thermoplastic product, combining localized heating with mold bending plasticity. This replaces the previous method of first heating and softening before transferring the product to the mold for bending, significantly reducing reliance on worker skill and experience, and minimizing unforeseen complications.

[0039] A connecting column 108 is provided to connect the main base 101 and the parting cover plate 104. Air is drawn out through the air extraction pipe 103 and the top through hole of the connecting column 108, and negative pressure is generated in the corresponding connecting grooves on the connecting column 108 and the parting cover plate 104 to ensure that the parting cover plate 104 is tightly connected to the main base 101, thereby ensuring the overall integrity of the bending groove 105.

[0040] A guide slider 109 is provided to guide the insertion and movement of the thermoplastic product. Several ball bearings 111 are rolled on the outer wall of the guide slider 109. The rolling of the ball bearings allows the guide slider 109 to smoothly guide the thermoplastic product into the bending groove 105, preventing the softened thermoplastic product from deforming due to hitting the bend of the bending groove 105. The main base 101 has multiple modules, each with its own parting plate 104 and a bending groove 105 with a different bending shape. This allows for simultaneous bending of multiple thermoplastic products and meets the needs of various bending shapes.
