Description

Technical Field

[0001] This utility model belongs to the field of stamping and forming technology, and in particular to a steel plate stamping and forming device for the production of polyurethane cold storage panels. Background Technology

[0002] Stamping is a process that uses a press and dies to apply external force to sheet metal, strip metal, pipe metal, and profile metal, causing plastic deformation or separation to obtain workpieces of the required shape and size. However, the production of polyurethane cold storage panels requires stamping of steel plates. In order to improve the processing efficiency of existing steel plate stamping equipment, a conveyor is installed to facilitate material loading, making the loading operation more time-saving and labor-saving. Although this saves time and labor to a certain extent, the dies are installed with multiple bolts, making it time-consuming and labor-intensive to disassemble them.

[0003] A search revealed Chinese patent documents (authorization announcement number CN221817196U), and this application provides a steel plate stamping and forming device for the production of polyurethane cold storage panels, relating to the field of polyurethane cold storage panel processing. The device includes a chassis mechanism, comprising a first chassis and a second chassis. The first chassis is located on one side of the second chassis. A feeding mechanism is fixedly installed on the top of the first chassis, including a conveying component and a power component. A shaping mechanism is fixedly installed on the top of the second chassis, including a buffer component fixedly installed inside the second chassis and a stamping component fixedly installed on the top of the second chassis. A worker places a steel plate into the device, and a motor is started to rotate, driving the conveyor rollers to rotate. While this patent makes the loading operation of the device more time-saving and labor-saving to some extent, the molds are installed using multiple bolts, making disassembly of the molds time-consuming and labor-intensive.

[0024] Working principle This steel plate stamping and forming device for producing polyurethane cold storage panels operates as follows: The lower mold 6 is placed at the designated position on the top of the workbench 1, ensuring the side positioning block 7 is aligned with the adjusting plate 9. The second electric push rod 12 is activated, its drive end retracts, causing the support column 13 to descend. The support column, through the movable rod 14, pulls two sliders 11 to slide relative to each other along the sliding rod 10. The adjustment of the sliders 11 causes the adjusting plate 9 to move synchronously, allowing the positioning rod 8 to insert into the positioning hole at one end of the positioning block 7, thus fixing the lower mold 6. For disassembly, the second electric push rod 12 is activated in reverse, causing the support column 13 to rise and push the sliders 11 apart, allowing the positioning rod 8 to exit the positioning hole. The conveyor... 42. The steel plate to be stamped is transported to the material picking position on the side of the workbench 1. The linear motor 41 drives the mounting bracket 43 to move vertically and horizontally, so that the fixing plate 44 is aligned with both ends of the steel plate. The drive motor 49 drives the lead screw 47 to rotate, so that the two moving blocks 48 move relative to each other along the extension direction of the lead screw 47. The fixing plate 44 approaches and clamps the steel plate synchronously. The linear motor 41 is started to drive the mounting box 46 to lift to a certain height, and the first electric push rod 45 is started to drive the mounting box 46 to move horizontally, transferring the steel plate to the stamping position at the top of the lower mold 6. Then the fixing plate 44 releases the steel plate, completing the loading. The hydraulic rod 5 is started to perform the stamping and forming process.
