[0002] Fire doors are doors that can meet the requirements of fire resistance stability, integrity, and heat insulation within a certain period of time. They are fire-resistant partitions with a certain degree of fire resistance, installed in fire-resistant compartments, evacuation stairwells, vertical shafts, and other similar locations. Currently, the small-scale stamping equipment for iron fire doors requires manual insertion of the components into the stamping die during the overall stamping process. If operational errors occur during this process, it can easily lead to hand trapping or other dangerous situations. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a manufacturing equipment and process for iron fire doors, thereby solving the problem that existing small stamping equipment for iron fire doors requires manual insertion of the components into the stamping die during the overall stamping of iron fire door parts. In this process, if operational errors occur, it can easily lead to hand pinching or other dangerous situations.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a manufacturing equipment for iron fire doors, comprising a stamping base and an arched stamping frame. The arched stamping frame is mounted on the upper end of the stamping base. A quick-release heating stamping mechanism is movably mounted on the inner side of the arched stamping frame. A cylinder is provided at the upper end of the arched stamping frame to drive the quick-release heating stamping mechanism to move up and down. A workpiece stamping die base corresponding to the quick-release heating stamping mechanism is provided in the middle of the upper surface of the stamping base. A workpiece positioning slot is provided in the middle of the workpiece stamping die base. A sliding groove is horizontally provided on one side of the inner wall of the workpiece positioning slot. An electromagnetic chuck is slidably mounted in the sliding groove. The electromagnetic chuck's suction end faces the workpiece positioning slot. A micro motor is provided on the inner wall of the rear part of the sliding groove. An internally threaded tube is provided on the outer wall of the electromagnetic chuck. The output end of the micro motor faces the electromagnetic chuck and is driven by a lead screw threaded to the internally threaded tube. A receiving slot is provided at the rear end of the workpiece positioning slot. A limiting block is movably provided on the receiving slot. An electromagnet that generates magnetic attraction force on the limiting block is provided in the middle of the bottom surface of the receiving slot. A spring rod is vertically provided on the edge of the bottom surface of the receiving slot. A positioning slot that fits into the spring rod is provided on the bottom surface of the limiting block. A control panel for controlling the operation of the electromagnetic chuck, micro motor, and electromagnet is provided at the front end of the workpiece stamping die base.

[0005] Furthermore, the quick-release heating stamping mechanism includes a connecting plate and a stamping template. The connecting plate has an assembly slot on its bottom surface. The top of the stamping template is embedded in the assembly slot. A fixing bolt that is threadedly connected to the stamping template is screwed onto the outside of the assembly slot. A heat-conducting plate is provided in the interlayer of the stamping template. Multiple heat-conducting rods are vertically provided at the top of the heat-conducting plate. The heat-conducting rods protrude from the top surface of the stamping template. A heat-conducting sleeve that is sleeved with the heat-conducting rods is provided on the inner wall of the top of the assembly slot. An electric heating element that transmits heat to the heat-conducting sleeve is provided inside the connecting plate.

[0006] Furthermore, when the limiting block retracts into the receiving groove, the top surface of the limiting block and the bottom surface of the workpiece positioning groove are on the same horizontal plane.

[0007] Furthermore, the stamping template is located directly above the workpiece positioning slot.

[0008] Furthermore, the inner wall of the sliding groove is provided with a slide rail to restrict the rotation of the electromagnetic chuck.

[0009] Furthermore, the rear end of the workpiece stamping die base is connected to a conductive wire that supplies power to the electromagnetic chuck, micro motor, and electromagnet.

[0010] Furthermore, the limiting block has a cuboid structure, and the length of the limiting block is equal to the distance that the lead screw drives the electromagnetic chuck to move horizontally through the internal threaded tube.

[0011] Several manufacturing processes for iron fire door manufacturing equipment are also provided, as follows:

[0012] Step S1: Insert the component of the iron fireproof door panel that needs to be stamped into the workpiece positioning slot. After the rear end of the component abuts against the limiting block, release it. At this time, the front end of the component extends beyond the workpiece stamping die base.

[0013] Step S2: Next, operate the control panel. The control panel controls the operation of the electromagnetic chuck through a pre-written program. The electromagnetic chuck attracts and positions the part. At the same time, the electromagnet is energized, which pulls the limit block into the receiving slot. The spring on the spring rod is compressed and deformed. Then, the micro motor drives the lead screw to rotate. The lead screw drives the threaded internal thread tube, which drives the electromagnetic chuck to move horizontally backward. The electromagnetic chuck drives the part to fully enter the workpiece positioning slot.

[0014] In step S3, the cylinder drives the quick-release heating and stamping mechanism to move down and stamp the part that is completely located in the workpiece positioning slot. When the part has a certain thickness and needs to be hot-pressed, a stamping template with hot-pressing function can be assembled. The heat-conducting rod on the stamping template is nested into the heat-conducting sleeve. As the heating element inputs heat into the heat-conducting sleeve, the heat is transferred to the heat-conducting plate in the stamping template through the heat-conducting rod, causing the entire stamping template to heat up.

[0015] The beneficial effects of this invention are: a magnetic drive automatic feeding and discharging structure is provided on the small stamping equipment for manufacturing iron fire doors, which effectively prevents the occurrence of hand pinching or other dangerous situations, and improves the convenience of workers in feeding and picking up materials. At the same time, the stamping structure is equipped with a detachable stamping template, which can be quickly replaced according to different parts and the corresponding stamping method can be selected, which greatly improves the stamping efficiency.

[0024] To select different stamping methods for components of varying thicknesses, the quick-release heated stamping mechanism 3 includes a connecting plate 301 and a stamping template 302. The bottom surface of the connecting plate 301 is provided with an assembly slot 303. The top of the stamping template 302 is embedded in the assembly slot 303. A fixing bolt 304, threadedly connected to the stamping template 302, is screwed onto the outside of the assembly slot 303. A heat-conducting plate 305 is provided inside the interlayer of the stamping template 302. Multiple heat-conducting rods 306 are vertically provided at the top of the heat-conducting plate 305.

An electric heating element 308, which supplies heat to the heat-conducting sleeve 307, is provided inside the connecting plate 301.

[0025] To prevent the limiting block 13 from interfering with the fully inserted component, when the limiting block 13 is retracted into the receiving groove 12, the top surface of the limiting block 13 and the bottom surface of the workpiece positioning groove 6 are on the same horizontal plane.

[0026] In order to carry out normal stamping work, the stamping template 302 is located directly above the workpiece positioning slot 6.

[0027] In order to drive the electromagnetic chuck 8 to move horizontally, the inner wall of the sliding groove 7 is provided with a slide rail to restrict the rotation of the electromagnetic chuck 8.

[0028] For normal operation, the rear end of the workpiece stamping die base 5 is connected to a conductive wire that supplies power to the electromagnetic chuck 8, the micro motor 9, and the electromagnet 14.

[0029] In order to drive the component to fully extend into the workpiece positioning slot 6, the limiting block 13 is a cuboid structure, and the length of the limiting block 13 is equal to the distance that the lead screw 11 drives the electromagnetic chuck 8 to move horizontally through the internal threaded tube 10.

[0030] A manufacturing process for an iron fire door manufacturing equipment is also provided, including the following process steps:

[0031] Step S1: Insert the component of the iron fireproof door panel that needs to be stamped into the workpiece positioning slot 6. After the rear end of the component abuts against the limiting block 13, release it. At this time, the front end of the component extends beyond the workpiece stamping die base 5, effectively preventing hand pinching or other accidents.

[0032] Step S2: Next, operate the control panel 17. The control panel 17 controls the operation of the electromagnetic chuck 8 through a pre-written program. The electromagnetic chuck 8 attracts and positions the part. At the same time, the electromagnet 14 is energized, which pulls the limit block 13 into the storage slot 12. The spring on the spring rod 15 is compressed and deformed. Then, the micro motor 9 drives the lead screw 11 to rotate. The lead screw 11 drives the threaded internal thread tube 10. The internal thread tube 10 drives the electromagnetic chuck 8 to move horizontally backward. The electromagnetic chuck 8 drives the part to fully enter the workpiece positioning slot 6 without the need for manual pushing of the part.

[0033] In step S3, cylinder 4 drives quick-release heating and stamping mechanism 3 to move down and stamp the part that is completely located in workpiece positioning slot 6. When the part has a certain thickness and needs to be hot-pressed, a stamping template 302 with hot-pressing function can be assembled. The heat-conducting rod 306 on the stamping template 302 is nested into the heat-conducting sleeve 307. As the heating element 308 inputs heat into the heat-conducting sleeve 307, the heat is transferred to the heat-conducting plate 305 in the stamping template 302 through the heat-conducting rod 306, so that the entire stamping template 302 heats up.

[0034] After the stamping process is completed, the electromagnetic chuck 8 can also attract the parts and extend out of the workpiece stamping die base 5, improving the convenience of material removal and demolding.
