Description

Technical Field

[0001] This utility model relates to the field of pressing machine technology, specifically a thermoforming pressing machine. Background Technology

[0002] Thermosensitive molding and pressing machines are specialized pieces of equipment that play a vital role in industrial production and related fields. They primarily utilize the properties of thermosensitive materials, employing specific processes and mechanical structure designs to perform molding and pressing operations on various materials. These machines typically feature precise temperature control, pressure regulation, and time setting functions, ensuring that the materials undergo physical or chemical changes under suitable thermal and pressure conditions during processing, thereby achieving the desired molding and pressing effects.

[0003] The existing patent announcement number CN219274176U discloses an aluminum alloy forming stamping machine, including a base. A support leg is fixedly connected to the bottom of the base, and a die is fixedly connected to the upper end of the base. A demolding mechanism is provided inside the die. A bracket is fixedly connected to the upper end of the base, and a cylinder is provided at the top of the bracket. The piston rod of the cylinder is slidably connected to the bracket, and a connecting sleeve is bolted to the piston rod. By providing a demolding mechanism inside the die of the stamping machine, when the punch enters the die and jointly stamps the aluminum alloy blank, the top plate in the demolding mechanism presses down and compresses the first spring until the travel sleeve on the top plate abuts against the bottom of the die. When the punch and die separate, the first spring pushes the top plate back, thereby ejecting the formed aluminum alloy product from the die and preventing the product from getting stuck in the die and difficult to demold.

[0004] Using the above technical solution, when stamping workpieces, operators need to manually feed the workpieces, requiring frequent hand contact with the mold area. This increases the risk of hand injuries due to misoperation or equipment malfunction. Furthermore, manual placement of the workpiece can easily lead to positional deviations, resulting in inaccurate stamping positions or mold impacts. Therefore, we provide a thermal forming press machine. Utility Model Content

[0021] This utility model provides a technical solution: such as Figures 1-4 As shown, in this embodiment, a thermoforming pressing machine includes a processing table 11. A protective cover 12 is fixedly connected to one side of the top of the processing table 11. A fixed shell 13 is disposed in a slot opened on the top of the processing table 11, and a transfer frame 18 is disposed inside the fixed shell 13. A support 14 is disposed on one side of the top of the processing table 11, and a reciprocating motor 15 is disposed on the top of the support 14. A rotating rod 16 is disposed at one end of the reciprocating motor 15 near the protective cover 12. The fixed shell 13 is fixedly connected to the slot opened on the top of the processing table 11. A support 14 is fixedly connected to one side of the top of the workbench 11. The top of the support 14 is fixedly installed on the outside of the reciprocating motor 15. The output end of the reciprocating motor 15 is fixedly connected to one end of the rotating rod 16. Two levers 17 are provided on the outside of the rotating rod 16. A feed hopper 19 is provided on the side of the top of the workbench 11 near the fixed housing 13. An inclined surface 110 is provided on the top of the fixed housing 13 near the feed hopper 19.

The output end of the top of the cylinder 114 is fixedly connected to the bottom of the top plate 115. The outside of the top plate 115 passes through the groove opened at the bottom of the feed hopper 19 near the fixed shell 13. A hydraulic cylinder 31 is fixedly installed on the top of the protective cover 12. A hot press plate 32 is fixedly installed on the bottom of the hydraulic cylinder 31. A lower mold 33 is provided on the top of the processing table 11 near the interior of the protective cover 12. A gripper mechanism 2 is provided on the top of the processing table 11.

[0022] In this embodiment, when the device is used to perform thermoforming on workpieces, multiple workpieces are first placed in the feed hopper 19. The feed hopper 19 has a sloping interior, and the workpieces will slide down sequentially to a position near the top plate 115. To ensure that the workpieces do not accumulate in the feed hopper 19, the limiting slide groove 111 and the limiting slide column 113 can be used to push and pull the sorting plate 112 to orderly sort the workpieces in the feed hopper 19, making it easier for the top plate 115 to lift the workpieces one by one, thus avoiding jamming caused by excessive workpiece pushing. The starting cylinder 114 can drive the top plate 115 to lift the orderly arranged workpieces. During the lifting process, the reciprocating motor 15 is started to drive the rotating rod 16 to rotate 90°, which can push the lifted workpieces to the inclined surface 110 opened in the fixed shell 13. After the transfer frame 18 is started, the workpieces placed on it are transferred in sequence. The mechanical gripper 27 is used to transport the workpieces to the lower mold 33 inside the protective cover 12. The hot press plate 32 is heated, and after the hydraulic cylinder 31 is started, the heated hot press plate 32 is used to perform thermoforming and pressing processing on the workpieces.

[0023] like Figures 1-4 As shown, the gripper mechanism 2 includes a mounting shell 21. A support column 22 is fixedly connected to one side of the bottom of the mounting shell 21. The bottom of the support column 22 is fixedly connected to the top of the processing table 11. The other side of the bottom of the mounting shell 21 is fixedly installed to the top of the protective cover 12. A support plate 23 is fixedly connected to the side of the mounting shell 21 away from the protective cover 12. A drive motor 24 is fixedly installed on the top of the support plate 23. The output end of the drive motor 24 is fixedly connected to one end of a lead screw 25. The outside of the lead screw 25 is threadedly connected to a threaded groove in a moving block 26. A mechanical gripper 27 is movably installed on the bottom of the moving block 26.

[0024] In this embodiment, when it is necessary to clamp the workpiece placed on the transfer frame 18, the drive motor 24 can be started to drive the lead screw 25 to rotate. Therefore, the moving block 26 will move on the lead screw 25. After the mechanical gripper 27 is started to clamp the workpiece, the drive motor 24 can be started again to transport the workpiece gripped by the mechanical gripper 27 to the lower mold 33 for subsequent processing.

[0025] This utility model provides a thermosensitive molding and pressing machine, the specific working principle of which is as follows: When the device is used for thermoforming of workpieces, the operator first places a batch of workpieces into the inclined feed hopper 19. Under the action of gravity, the workpieces slide down the slope in an orderly manner to the top plate 115. To ensure continuous and stable feeding, the device is equipped with an automatic sorting mechanism linked by the limiting slide groove 111 and the limiting slide column 113. The sorting plate 112 is periodically pushed and pulled to keep the workpieces in a single-layer arrangement. After the workpieces are in place, the control system starts the lifting cylinder 114, which drives the top plate 115 to precisely lift the bottom layer of workpieces. At the moment the lifting action is completed, the reciprocating motor 15 immediately drives the rotating rod 16 to perform a 90° rotation. The lifted workpiece is smoothly pushed onto the guide ramp 110 of the fixed shell 13. After the workpiece slides down the ramp 110, it is received by the synchronously started transfer frame 18 and transported to the gripping station. At this time, the drive motor 24 drives the precision lead screw 25 to rotate, so that the moving block 26 is precisely positioned along the guide rail. The mechanical gripper 27 then completes the workpiece gripping action. Finally, the drive motor 24 runs again, driving the mechanical gripper 27 holding the workpiece to move above the thermoforming mold, accurately placing the workpiece in the designated position in the lower mold cavity, heating the hot press plate 32, and starting the hydraulic cylinder 31 to perform thermoforming pressing on the workpiece using the heated hot press plate 32.
