Description
Technical Field
[0001] This utility model relates to the field of composite material processing, and more particularly to a welding device for composite materials. Background Technology
[0002] The history of composite materials can be traced back to ancient times. The rice straw or wheat straw reinforced clay used from ancient times to the present and the reinforced concrete that has been used for hundreds of years are both made of two materials. These high-strength, high-modulus fibers can be combined with non-metallic matrices such as synthetic resins, carbon, graphite, ceramics, and rubber, or metallic matrices such as aluminum, magnesium, and titanium to form composite materials with their own characteristics.
[0003] The development of modern high technology is inseparable from composite materials. Composite materials play a vital role in the development of modern science and technology. The depth of research and the breadth of application of composite materials, as well as the speed and scale of their production development, have become one of the important indicators for measuring the level of scientific and technological advancement of a country.
[0004] Currently, in the use of composite material resistance welding equipment, because the electrode clamping mechanism and motor adopt an integrated structure design, it can only clamp and weld products of fixed specifications. If it is necessary to change to products of different specifications, the clamping mechanism must be replaced as well, which is quite troublesome and has poor versatility. Otherwise, oxidation will occur at the welded end, which not only makes the welding process more complicated, but also seriously reduces the welding efficiency.
[0005] Existing technology has flaws and needs improvement. Utility Model Content

[0013] Preferably, the base frame also includes a power supply and a controller, which are located on one side of the heating device.
[0014] Compared to the advantages of existing technologies, this utility model is particularly useful because composite materials are widely used and come in various shapes.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.
[0025] The present invention will now be described in detail with reference to the accompanying drawings.
[0026] like Figure 1-Figure 5 As shown: A welding device for composite materials includes a base frame, a welding device, and a heating device. The welding device and the heating device are both mounted on the base frame, and the heating device is located on one side of the welding device. The welding device includes an upper mold unit, a lower mold unit, and a lower pressing unit. The lower mold unit is mounted on the base frame and arranged parallel to the heating device. The lower pressing unit is located above the lower mold unit, and the upper mold unit is located at the lower end of the lower pressing unit and is arranged opposite to the lower mold unit.
[0027] It should be noted that because the composite materials are widely used and come in various shapes, some products cannot be directly injection molded by an injection molding machine in one go. In such cases, butt welding is required. When two different composite materials are placed into the upper mold unit and the lower mold unit respectively, firstly, the pressing unit drives the upper mold unit to separate from the lower mold unit. Then, the heating device slides laterally between the lower mold unit and the upper mold unit. Subsequently, the pressing unit drives the upper mold unit to press down, heating the joint between the two composite materials in the upper mold unit and the lower mold unit. Then, when the temperature reaches the set value, the pressing unit drives the upper mold unit to rise, the heating device slides out, and the pressing unit presses down again to weld the two composite materials in the upper mold unit and the lower mold unit together. After forming, the pressing unit rises and the composite material is removed from the lower mold unit.

The output ends of the first heating cylinder and the second heating cylinder are both connected to one end of the heating clamp. The heating plate is installed on the heated furniture.
[0030] It should be noted that the slide rail cylinder drives the slide rail bracket to slide on the first and second slide rails, so that the heating plate on the slide rail bracket moves laterally into the welding device to heat the composite material. The first and second heating cylinders drive the heating fixture to move the heating plate up and down, and then retract after heating the composite material in cooperation with the welding device.
[0031] Preferably, the lower mold unit includes a T-shaped plate, a lower mold support, multiple columns, multiple vacuum suction cups, a first finger cylinder, and a second finger cylinder.

The multiple support plates are arranged opposite to each other and are located on one side of the upper mold cylinder. The temperature sensor is located on one side of the upper mold cylinder. Multiple fixing discs are arranged at the bottom of the multiple support plates.
[0036] It should be noted that the upper mold cylinder and multiple fixing plates are used to fix the upper mold composite material set inside the upper mold bracket, while the temperature sensor is used to sense the welding temperature of the composite material and to cooperate with the heating plate for heating.
[0037] Furthermore, the bottom of the upper mold support is provided with an upper mold hole for installing composite materials, and the upper mold hole is also set to an irregular shape.
[0038] Preferably, the pressing unit includes multiple guide seats, multiple guide shafts, multiple linear guides, a pressing plate, a pressing motor, a pressing fixing plate, and a pressing sliding rod. The multiple guide seats are arranged sequentially and at intervals on the base frame.

[0040] Furthermore, the downward pressure motor drives the downward pressure sliding rod to make the downward pressure plate slide up and down within multiple guide shafts, thereby driving the upper mold unit to move up and down and press down for welding.
