Description

Technical Field

[0001] The utility model belongs to the technical field of plastic plate processing, and in particular relates to a plastic plate forming tool. Background Art

[0002] In the production of products requiring specific shapes, such as U-shaped structures, traditional methods for forming U-shaped plastic sheets rely primarily on manual operation, mold pressing, or thermoforming. While these methods meet production needs to a certain extent, they all have significant limitations.

[0003] Thermoforming technology heats a plastic sheet to a softened state and then uses external forces (such as air pressure or mechanical pressure) to deform it into the desired shape. However, traditional thermoforming equipment is often complex and cumbersome to operate. Furthermore, custom molds are required for different sizes and shapes of U-shaped sheets, increasing production complexity and cost. While manual operation is flexible, it relies heavily on the operator's skill and experience, resulting in low production efficiency and difficulty in ensuring molding quality. This method is particularly problematic in large-scale production. Utility Model Content

[0004] In response to the above problems, the purpose of this utility model is to provide a plastic plate forming tool to solve the problems of traditional plastic plate U-shaped forming methods that rely heavily on manual operation or complex molds, resulting in low production efficiency, poor forming accuracy, and high labor costs.

[0008] As a further improvement of the above technical solution: a temperature sensor is installed on the fixing plate on one side of the electric heating tube, and the temperature controller is electrically connected to the temperature sensor and the electric heating tube.

[0009] The beneficial effect of this improvement is that the temperature controller can stably control the operating state of the electric heating tube, so that the electric heating tube can stably heat the plastic plate.

[0010] In order to effectively ensure the safety of the use of electric heating tubes;

[0011] As a further improvement of the above technical solution: the top surface of the safety baffle is flush with the top surface of the fixed plate, and the safety baffle is a high-temperature resistant glass plate.

[0012] The beneficial effects of this improvement are: the safety baffle can maintain stable performance in a high temperature environment, and the heat radiation energy of the electric heating pipe can easily penetrate or pass through the safety baffle, while isolating and protecting the electric heating pipe and effectively heating the plastic plate.

[0013] In order to achieve fast and accurate positioning of the bending area of ​​the plastic plate;

[0014] As a further improvement of the above technical solution: the movable block and the fixed block are both square plate structures, and the axes of the pins at both ends of the connecting rod are parallel to the axis of the rotating shaft.

[0015] The beneficial effect of this improvement is that after the plastic plate is heated by being pressed against the surface of the movable block, the movable block is flipped and moved so that one end of the plastic plate is pressed against the fixed block, and the softened part of the plastic plate can be moved above the rotating shaft to achieve fast and accurate bending.

[0016] In order to ensure the stability of the installation of the limit block;

[0017] As a further improvement of the above technical solution: the number of the adjustment slots is two, and they are opened on the rotating plate opposite to each other on the left and right sides.

[0018] The beneficial effect of this improvement is that the two adjustment slots cooperate with the two fastening bolts to stably lock the fixing block, thereby ensuring the installation stability of the limit block.

[0019] In order to fully ensure the safety of the electric heating tube;

[0020] As a further improvement of the above technical solution: the fixed plate below the electric heating tube is padded with heat insulation cotton.

[0021] The beneficial effect of this improvement is that the provision of thermal insulation cotton can effectively improve the safety of the electric heating tube during operation.

[0022] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

The heated and softened plastic plate is easily bent into a U shape by using a rotary molding structure that can limit the plastic plate. The whole process is efficient and smooth, which significantly improves the production efficiency; the limit block 6 can flexibly adjust the position, so that it can easily meet the processing needs of plastic plates of different specifications. A temperature sensor is installed on the fixed plate 1 on one side of the electric heating tube 7. The thermostat 9 is electrically connected to the temperature sensor and the electric heating tube 7. The thermostat 9 can stably control the operating state of the electric heating tube 7. The safety baffle 8 is flush with the top surface of the fixed plate 1, and the safety baffle 8 is a high-temperature resistant glass plate. The safety baffle 8 can maintain stable performance in a high-temperature environment, and the heat radiation energy of the electric heating tube 7 can easily penetrate or pass through the safety baffle 8, while isolating and protecting the electric heating tube 7, effectively heating the plastic plate. The movable block 63 and the fixed block 61 are both square plate structures. The axes of the pins at both ends of the connecting rod 62 are parallel to the axis of the rotating shaft 2. When the plastic plate is against the movable block 63, the fixed block 61 is parallel to the axis of the rotating shaft 2. After the surface is heated, the movable block 63 is flipped and moved so that one end of the plastic plate is against the fixed block 61, and the softened part of the plastic plate can be moved above the rotating shaft 2 to achieve fast and accurate bending. There are two adjusting slots 4, which are relatively opened on the rotating plate 3 on the left and right. The two adjusting slots 4 can be used with two fastening bolts 5 to stably lock the fixed block 61 to ensure the installation stability of the limit block 6. The fixed plate 1 under the electric heating tube 7 is padded with thermal insulation cotton.
