Description

Technical Field

[0001] This utility model relates to the field of thin-walled sheet metal forming technology, specifically to a rapid forming device for thin-walled sheet metal parts. Background Technology

[0002] Thin-walled sheet metal parts refer to components manufactured from thin metal sheets through a series of processing techniques. They are widely used in many fields such as automobiles, home appliances, aerospace, communication equipment, electronic products, and industrial machinery. Due to their advantages such as lightweight, high strength, and high processing precision, thin-walled sheet metal parts have become a very important type of component in modern industry.

[0003] Some thin-walled sheet metal parts can be rapidly formed by stamping. Before stamping, the corresponding lower die needs to be installed and fixed on the work platform. General forming equipment has difficulty in quickly installing and fixing the lower die. When producing different thin-walled sheet metal parts, changing the lower die takes a lot of time, resulting in low forming efficiency for thin-walled sheet metal parts. At the same time, the stamped thin-walled sheet metal parts need to be cut to remove excess edges and corners. General forming equipment has limited functions, and workers need to further process the edges and corners, resulting in low production efficiency for thin-walled sheet metal parts. To address the above problems, a rapid forming device for thin-walled sheet metal parts is proposed. Utility Model Content

[0004] To address the aforementioned technical problems, a rapid prototyping device for thin-walled sheet metal parts is provided. This device solves the problem that while some thin-walled sheet metal parts can be rapidly formed by stamping, the corresponding lower mold needs to be installed and fixed on the work platform before stamping. General forming devices often struggle to quickly install and fix the lower mold, and changing the lower mold when producing different thin-walled sheet metal parts takes considerable time, resulting in low forming efficiency. Furthermore, the stamped thin-walled sheet metal parts require cutting to remove excess edges and corners. General forming devices have limited functionality, requiring further edge and corner processing by operators, further contributing to the low production efficiency of thin-walled sheet metal parts.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a rapid prototyping device for thin-walled sheet metal parts, comprising a work platform, a T-shaped slide rail fixedly connected to the upper left end of the work platform, a Y-shaped connecting slide rail fixedly connected to the right side of the T-shaped slide rail, a lower mold slidably connected to the surface of the T-shaped slide rail via a T-shaped groove, fixed plates fixedly connected to the lower ends of both the front and rear sides of the lower mold, a positioning rod slidably connected to the upper center position of the fixed plate, a positioning hole opened on the upper side of the work platform and below the fixed plate, the lower end of the positioning rod penetrating the upper side of the fixed plate and slidably connected to the interior of the positioning hole, a sliding plate fixedly connected to the upper side of the positioning rod, a spring sleeved on the surface of the positioning rod, the upper end of the spring fixedly connected to the lower side of the sliding plate, and the lower end of the spring... The upper side of the end is fixedly connected to the fixed plate. A connecting block is fixedly connected to the center position of the upper side of the slide plate. A pin is slidably connected to the outer side of the connecting block. The end of the pin passes through the outer side of the connecting block and is fixedly connected to the fixed block. The front and rear ends of the upper side of the working platform are fixedly connected to the mounting supports. A stamping push rod is fixedly installed at the center position of the upper side of the mounting support. The output end of the stamping push rod passes through the upper side of the mounting support and is fixedly connected to the mounting rod. A mounting box is slidably connected to the surface of the mounting rod. Cutters are provided at the four sides of the lower side of the mounting box. Several mounting holes are opened through the right side of the mounting rod. High-strength bolts are threaded to both sides of the mounting box. The ends of the high-strength bolts pass through the surface of the mounting box and are threaded to the inside of the mounting holes.

[0006] Preferably, a handle is fixedly connected to the outside of the pin.

[0007] Preferably, the upper ends of both the front and rear sides of the lower mold are provided with fixing holes, and the fixing block is slidably connected to the inside of the fixing hole.

[0008] Preferably, the lower side of the mounting rod is engaged with an upper mold.

[0009] Preferably, support legs are fixedly connected to the four lower corners of the work platform.

[0010] Preferably, a model groove is provided at the center of the upper side of the lower mold.

[0011] Compared with the prior art, the advantages of this utility model are as follows: By setting up a T-shaped slide rail, a Y-shaped connecting slide rail, a fixing plate, a positioning rod, a positioning hole, a sliding plate, and a spring, the lower mold can be quickly installed and fixed. When producing different thin-walled sheet metal parts, the time spent on changing the lower mold is reduced, and the forming efficiency of thin-walled sheet metal parts is improved. By setting up an installation rod, an installation box, a cutting tool, an installation hole, and high-strength bolts, excess edges and corners can be cut off during stamping, increasing the punching function and avoiding further edge and corner processing by workers, thereby improving the production efficiency of thin-walled sheet metal parts.

The lower mold 5 is slidably connected to the surface of the T-shaped slide rail 3 through a T-shaped slide groove 6. A model groove 7 is provided at the upper center of the lower mold 5.

[0018] Specifically, a fixing plate 8 is fixedly connected to the lower ends of both the front and rear sides of the lower mold 5. A positioning rod 9 is slidably connected to the upper center of the fixing plate 8. A positioning hole 10 is opened on the upper side of the working platform 1 and below the fixing plate 8. The lower end of the positioning rod 9 passes through the upper side of the fixing plate 8 and is slidably connected to the inside of the positioning hole 10, which can effectively fix the position of the lower mold 5 and prevent the lower mold 5 from sliding. A sliding plate 11 is fixedly connected to the upper side of the positioning rod 9. A spring 12 is sleeved on the surface of the positioning rod 9. The upper end of the spring 12 is fixedly connected to the lower side of the sliding plate 11, and the lower end of the spring 12 is fixed to the fixing plate 8. The upper side of 8 is fixedly connected to ensure that the lower end of the positioning rod 9 can be inserted into the interior of the positioning hole 10. A connecting block 13 is fixedly connected at the center of the upper side of the slide plate 11. A pin 14 is slidably connected to the outside of the connecting block 13. A handle 15 is fixedly connected to the outside of the pin 14 to facilitate pulling the pin 14. The end of the pin 14 passes through the outside of the connecting block 13 and is fixedly connected to a fixing block 16. Fixing holes 17 are opened at the upper ends of both the front and rear sides of the lower mold 5. The fixing block 16 is slidably connected to the interior of the fixing hole 17 to control the position of the lower end of the positioning rod 9 and prevent it from affecting the sliding of the lower mold 5.

[0019] Specifically, mounting supports 18 are fixedly connected to the front and rear ends of the upper side of the work platform 1. A stamping push rod 19 is fixedly installed at the center of the upper side of the mounting support 18. The output end of the stamping push rod 19 passes through the upper side of the mounting support 18 and is fixedly connected to a mounting rod 20. An upper mold 21 is snapped into the lower side of the mounting rod 20. The upper surface of the upper mold 21 can be snapped into the lower end of the mounting rod 20 by rotation. A mounting box 22 is slidably connected to the surface of the mounting rod 20. Cutters 23 are set at the four sides of the lower side of the mounting box 22. The mounting box 22 and the cutter 23 of appropriate height are selected according to the thickness of the metal sheet and the thickness of the upper mold 21. Several mounting holes 24 are opened through the right side of the mounting rod 20. High-strength bolts 25 are threadedly connected to both sides of the mounting box 22.

[0020] Working principle: First, place the lower mold 5 to be used on the Y-shaped connecting slide rail 4. Then, slide the lower mold 5 to the left so that it slides on the T-shaped slide rail 3. When the lower mold 5 moves directly below the mounting rod 20, pull the handle 15 outward. The fixing block 16 disengages from the fixing hole 17. Under the elastic force of the spring 12, the slide plate 11 and the positioning rod 9 move downward. The positioning rod 9 inserts into the positioning hole 10. Under the constraint of the positioning rod 9 and the T-shaped slide rail 3, the installation and fixing of the lower mold 5 are completed. Select the appropriate height of the mounting box 22 and the cutter 23, and place the mounting box... First, move the mounting box 22 to the upper end of the mounting rod 20, fix the upper mold 21 to the lower end of the mounting rod 20, and then move the mounting box 22 to the corresponding height and fix it with high-strength bolts 25. Use the robot and clamps to place the metal sheet on the upper side of the lower mold 5. The stamping push rod 19 controls the mounting rod 20, the cutter 23 and the upper mold 21 to move downward. Under the action of the upper mold 21 and the lower mold 5, the metal sheet is pressed into shape. At the same time, the cutter 23 stamps the four sides of the metal sheet to remove excess edges and corners, thus completing the forming and production of thin-walled sheet metal parts.
