Description

Technical Field

[0001] This utility model relates to the field of thermoforming production line technology, specifically to a thermoforming heating furnace material sheet stop installation structure, which is suitable for matching multiple molds and realizing rapid positioning and centering of the material output from the heating furnace. Background Technology

[0002] With the acceleration of global economic activity, the concentration of carbon dioxide in the atmosphere continues to increase, and greenhouse gas emissions and global warming have become major environmental problems facing humanity. The automotive industry is one of the significant sources of greenhouse gas emissions. Studies show that a 10% reduction in vehicle weight can reduce fuel consumption by approximately 8% and emissions by 5-6%. Therefore, lightweighting of automobiles has become a crucial breakthrough direction for energy conservation and emission reduction. Thermoforming technology, due to its ability to produce high-precision, high-strength, and thin parts, has become the preferred technology for manufacturing automotive reinforcement plates and is widely used in the production of body structural components.

[0003] In recent years, thermoforming technology has developed rapidly in China's automotive manufacturing sector, with related technologies maturing and applications expanding rapidly. However, the high development cost and significant technological barriers of thermoforming molds have resulted in persistently high production costs. Therefore, improving the production efficiency of thermoforming production lines has become a key research topic for automotive parts suppliers. In thermoforming production lines, the heating furnace is a critical piece of equipment; its accuracy in material discharge positioning and mold-changing efficiency directly affect the overall performance of the production line. Traditional stopper installation structures have several shortcomings during mold-changing, mainly in the following aspects:

[0004] First, traditional stoppers are typically fixed to the main crossbeam with multiple screws, requiring individual screw removal each time a mold is changed, a cumbersome and time-consuming process. Second, adjusting the stopper's position relies on manual adjustment of its forward, backward, left, and right positions, lacking a fixed positioning benchmark, making it difficult to quickly determine the installation position and prone to deviations. Furthermore, the design of traditional stoppers does not adequately consider the needs of multi-mold matching; each mold change requires readjusting the stopper's position, increasing manual operation time and equipment waiting time, leading to resource waste such as dry running of the heating furnace. These problems not only reduce production efficiency but also increase labor costs and energy consumption, limiting the further development of thermoforming production lines towards high-efficiency, automated production.

[0005] To address the aforementioned issues, several improved stopper mounting structures have emerged in the market. For example, some structures simplify the installation process by adding positioning slots or clamping devices; however, these designs still require additional adjustment steps, and their positioning accuracy and ease of operation need further improvement. Furthermore, existing improved structures lack a universal positioning design when matching multiple molds, resulting in limited improvements in mold change efficiency. Therefore, there is an urgent need for a stopper mounting structure that enables rapid assembly and disassembly, precise positioning, and compatibility with multiple molds to improve the automation level and production efficiency of thermoforming production lines, while reducing operational complexity and production costs. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide an installation structure for a stopper for sheet material in a thermoforming heating furnace, which solves the problems of cumbersome mold changing operation and low positioning accuracy of traditional stopper installation structures, and realizes the functions of quick disassembly and assembly, precise positioning and adaptation to multiple molds.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A mounting structure for a stopper for sheet material in a thermoforming furnace includes a main crossbeam, a stopper, and screws. Multiple identical and spaced-apart pins are fixedly mounted on the main crossbeam. The stopper includes a mounting portion and a stopping portion. The mounting portion has positioning holes that fit onto the pins for positioning. One end of the stopping portion is connected to the mounting portion, and the other end contacts the sheet material exiting the furnace for stopping and positioning. The screws are located on the side of the mounting portion and press against the main crossbeam to fix the stopper to the main crossbeam.

[0009] Furthermore, the pins are arranged linearly along the length of the main crossbeam, and the spacing between the pins is equal.

[0010] Furthermore, the positioning hole of the mounting part matches the shape of the pin, forming a clearance fit.

[0011] Furthermore, the screw is disposed on the side of the mounting part, and by pressing against the side surface of the main crossbeam, a fixed structure is formed to prevent the stopper from moving relative to the main crossbeam.

[0012] Furthermore, the mounting part is concave, and the main crossbeam is located within the concave shape.

[0013] Furthermore, the stop portion and the mounting portion are integrally formed, and the stop portion extends outward from the edge of the mounting portion.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention provides an installation structure for a stopper for sheet material in a thermoforming heating furnace. By optimizing the installation and positioning method of the stopper, it significantly improves the mold changing efficiency and material discharge positioning accuracy of the thermoforming production line, providing important support for automated production.

[0016] Firstly, this invention achieves rapid and precise positioning of the stop by setting pins of the same size and evenly spaced intervals on the main crossbeam, which form a clearance fit with the positioning holes on the stop mounting part. The structural design of the positioning holes fitting onto the pins eliminates the need for additional adjustments to the stop's front-back, left-right, and right-side positions during installation, effectively avoiding the positional deviation problems caused by manual adjustment in traditional stop devices. This high-precision positioning structure ensures the centering stability of the material sheets during furnace discharge, thereby improving the processing quality of thermoformed parts.

[0017] Secondly, the mounting section of the stopper adopts a concave structure, with the main crossbeam located within the concave shape. Combined with the fixing method of screws tightening the main crossbeam from the side, the disassembly and assembly process of the stopper is simplified. Compared to the cumbersome operation of traditional stoppers requiring the removal of multiple screws, this invention only requires loosening the side screws to complete the stopper replacement, making operation convenient and significantly shortening mold change time. This quick-assembly and disassembly design is particularly suitable for thermoforming production lines with multiple molds, meeting the production needs of frequent mold changes and reducing manual operation time and equipment waiting costs.

[0018] Furthermore, the stop and mounting sections are integrally molded, with the stop extending outward from the edge of the mounting section to form a stable stop position in contact with the material sheet. This structure not only enhances the overall strength of the stop but also ensures the reliability of the material sheet's positioning during the furnace discharge process, preventing production interruptions caused by stop loosening or misalignment. The linear arrangement and equidistant spacing of the pins further ensure the consistency of stop installation on the main crossbeam for different molds, enhancing the structure's versatility and adaptability.

[0019] In summary, this utility model, through the cooperation of positioning holes and pins, the tightening and fixing of concave mounting parts and screws, and the design of an integrally formed stop part, achieves the functions of rapid installation, precise positioning, and stable stopping, significantly improving the automation efficiency and stability of thermoforming production lines, reducing production costs, and providing reliable technical support for the efficient production of lightweight automotive parts.

[0027] Please see Figure 1This is a stop installation structure for a thermoforming furnace material sheet, suitable for thermoforming production lines. It is used to match multiple molds and achieve rapid positioning and centering of the material exiting the furnace. The structure includes a main crossbeam 4, a stop 2, and screws 5. Multiple identical and spaced pins 3 are fixedly installed on the main crossbeam 4, arranged linearly along the length of the main crossbeam 4 with equal spacing between them, for positioning in conjunction with the stop 2.

[0028] The stopper 2 includes a mounting part and a stop part. The mounting part has a positioning hole that matches the shape of the pin 3, forming a clearance fit. The positioning hole is fitted onto the pin 3 to achieve precise positioning of the stopper 2 relative to the main crossbeam 4. The mounting part has a concave structure, with the main crossbeam 4 located within it. The positioning hole is located at the bottom of the concave structure, forming a fitted fit with the pin 3. One end of the stop part is connected to the mounting part, and the other end extends outward to contact the material sheet 1 exiting the heating furnace for stop positioning. The stop part and the mounting part are integrally formed, enhancing the overall strength and stability of the stopper 2.

[0029] Screw 5 is located on the side of the mounting part of the stopper 2. By tightening against the side surface of the main crossbeam 4, the stopper 2 is fixed to the main crossbeam 4. The screw 5 forms a tight connection with the side surface of the main crossbeam 4, preventing the stopper 2 from moving relative to the main crossbeam 4 and ensuring the stability of the installation structure.

[0030] In actual operation, when installing the stopper 2, simply fit the positioning hole of the mounting part onto the pin 3 on the main crossbeam 4. The stopper 2 can be quickly positioned by the linearly spaced, evenly spaced arrangement of the pins 3 and the clearance fit of the positioning holes. Then, by tightening the screw 5 on the side of the mounting part, it is pressed against the side surface of the main crossbeam 4, thus fixing the stopper 2. For disassembly, simply loosen the screw 5 to remove the stopper 2 and replace it with a stopper 2 suitable for other molds. No additional adjustments to the front, back, left, or right positions are required, making the operation simple and efficient.

[0031] This embodiment achieves rapid installation and precise positioning of the stopper 2 through the fitting of the positioning hole and the pin 3, the concave structure of the mounting part, and the side-tightening fixation of the screw 5. The contact design between the stop and the material sheet 1 ensures the centering accuracy of the material output from the heating furnace, adapts to the need for rapid changeover of multiple molds, and is suitable for the efficient operation of thermoforming production lines.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
