Its edge structure directly affects the sealing, safety and assembly accuracy of the hatch cover; the hatch cover edge positioning stamping is a technology that performs precise stamping processing on the edge area of ​​the hatch cover. The edge position of the hatch cover is fixed by a special positioning mechanism, and then the stamping die is used to perform specific processing on the edge.

[0003] Commonly used stamping devices are mainly composed of basic components such as the device body, control panel, stamping base, mold and power system. The control panel is used for operators to input instructions and monitor the operating status of the equipment. The stamping base provides a support platform for the mold and workpiece.

The positioning mark will generate an induced current under the action of the induced magnetic field and generate a secondary magnetic field. At this time, the electromagnetic induction coil 940 detects the change in the secondary magnetic field and converts the magnetic field change into an electrical signal through the electromagnetic induction principle. The control system converts the electrical signal transmitted by the electromagnetic induction coil 940 into a digital signal, and uses its internal preset mathematical model to accurately calculate the coordinate position of the positioning mark, and transmits the coordinate information to the control console 20 in a timely manner. 0, so that the staff can quickly know the position information of the hatch cover on the stamping seat 300, reduce positioning time and improve production efficiency; compared with the traditional manual positioning or positioning method relying on visual recognition, the time of each work cycle is greatly shortened, which is especially suitable for batch production scenarios; and this positioning method based on the principle of electromagnetic induction is not affected by factors such as light, hatch cover surface color or material, can work stably in complex industrial environments, and provide high positioning accuracy, meeting the strict requirements of hatch cover stamping on position accuracy. Its characteristics of not being disturbed by external environmental factors enable it to maintain stable positioning performance under different production conditions, effectively improving the accuracy of the hatch cover stamping position, thereby improving product quality.

[0040] In a preferred embodiment, the positioning mark is preferably a marking coating made of a highly magnetic material, and the upper mold 700, the punching seat 300 and the lower mold 400 are preferably made of a non-magnetic steel, and the upper mold 700 and the lower mold 400 are preferably made of a special non-magnetic mold steel. By adjusting the internal composition, the steel forms a stable austenitic structure, eliminates magnetism, and at the same time maintains the high hardness and wear resistance of the mold steel.

[0041] The hydraulic system 600 preferably adopts a hydraulic system 600 composed of a hydraulic cylinder and a hydraulic rod to meet the stamping requirements of the hatch cover.

[0042] like Figure 2 、 Figure 4 、 Figure 8 、 Figure 9 and Figure 10 As shown, as a preferred embodiment of the present invention, the adsorption positioning mechanism 500 includes a slide 510, a lifting assembly 520, a lifting block 530 and an adsorption assembly 540. The slide 510 is distributed on the stamping seat 300 and is slidably connected to the upper surface of the stamping seat 300. The slide 510 is installed with a lifting assembly 520, the lifting assembly 520 is installed with a lifting block 530, and the lifting block 530 is installed with an adsorption assembly 540 for adsorbing the outer surface of the hatch cover.

[0043] The lifting assembly 520 includes a guide column 521, a screw 522 and a screw sleeve 523. There are three guide columns 521, which are vertically fixed on three corners of the slide 510. The screw 522 is vertically fixed on another corner of the slide 510. The screw 522 and the guide column 521 are both vertically slidably matched with the lifting block 530, and a screw sleeve 523 threadedly connected to the screw 522 is installed on the outer side of the screw 522. The screw sleeve 523 is located at the bottom of the lifting block 530 and contacts its bottom end surface. The adsorption assembly 540 is installed on the top end surface of the lifting block 530.

[0044] The sliding seat 510 can slide to any position of the stamping seat 300, and the adsorption assembly 540 can effectively and sufficiently complete adsorption of the bottom end face of the hatch cover. The screw sleeve 523 can drive the lifting block 530 to move vertically by rotating on the screw rod 522, so as to change the adsorption height of the lifting block 530 and the adsorption assembly 540, so that the adsorption assembly 540 can be fully and effectively attached to the bottom end face of the hatch cover, thereby completing fixation of the hatch cover and precise positioning of the hatch cover by cooperating with the electromagnetic positioning mechanism 900, so as to ensure that the hatch cover is in the best positioning state before stamping, and improve the size precision and consistency of the stamped product. In addition, according to different shapes and sizes of the hatch cover, the position and number of the adsorption positioning mechanism 500 on the stamping seat 300 can be flexibly adjusted to adapt to diversified product requirements, and the adsorption positioning mechanism 500 can be applied to stamping positioning of various types of hatch covers, thereby improving the universality and applicability of the equipment.

[0045] In a preferred embodiment, the lifting assembly 520 can also adopt an automatic driving structure, for example, an automatic driving mechanism adopting a servo motor and a screw rod. The servo motor is electrically connected with a control system, and the control system can control the adsorption assembly 540 to rise to a specified position through the identification system arranged on the sliding seat 510, so that the adsorption assembly 540 can quickly and effectively complete positioning and adsorption of the outer surface of the hatch cover. The specific structure can be optimized and allocated according to actual production.

[0046] As shown in Figure 2 、 Figure 4 、 Figure 8 、 Figure 9 and Figure 10 , as a preferred embodiment of the present application, the adsorption assembly 540 comprises an adsorption seat 541, a sliding cavity 542, a sliding ball 543, an adsorption pipe 544, a suction nozzle 545 and a connecting hose 546. The adsorption seat 541 is fixed on the lifting block 530, the sliding cavity 542 for rotating installation of the sliding ball 543 is arranged in the adsorption seat 541, the adsorption pipe 544 is arranged in the middle of the sliding ball 543, one end of the adsorption pipe 544 extends out of the sliding cavity 542 and is fixedly connected with the suction nozzle 545, the other end of the adsorption pipe 544 is connected with the connecting hose 546, and one end of the connecting hose 546 penetrates through the through hole 547 arranged in the side wall of the adsorption seat 541 and is connected with an external suction pump.

[0047] Locking screws 549 and jackets 548 are installed on the four side walls of the adsorption seat 541. The locking screws 549 are located above the jacket 548. One end of the locking screw 549 extends into the sliding cavity 542 and intermittently contacts the outer surface of the sliding ball 543. The jacket 548 cooperates with the through hole 547 on the adsorption seat 541. The jacket 548 preferably adopts an annular sleeve structure made of silicone material. The inner wall of the jacket 548 can effectively and fully fit the outer wall of the connecting hose 546 of different diameters, thereby increasing the contact area between the connecting hose 546 and the adsorption seat 541, thereby improving the connection stability between the connecting hose 546 and the adsorption tube 544, and ensuring that the adsorption component 540 can effectively and continuously complete the positioning and adsorption of the hatch cover.

[0048] The sliding ball 543 can arbitrarily change the direction of the suction nozzle 545 by rotating in the sliding cavity 542, so that the suction nozzle 545 can be rotated to a position directly opposite the hatch cover, ensuring the fit between the two, and then the suction pump can achieve effective adsorption of the suction nozzle 545 and the bottom end face of the hatch cover by cooperating with the connecting hose 546 and the adsorption tube 544, thereby improving the adsorption stability between the suction nozzle 545 and the hatch cover, thereby completing the positioning and adsorption of hatch covers of different specifications and sizes; the locking screw 549 rotates to conflict with the surface of the sliding ball 543, thereby completing the restriction of the sliding ball 543, so that the sliding ball 543 can be stationary in the sliding cavity 542, thereby further improving the adsorption stability between the suction nozzle 545 and the hatch cover, ensuring that the hatch cover is in the best positioning state before stamping, and improving the dimensional accuracy and consistency of the stamping product.

[0049] like Figure 1 、 Figure 2 、 Figure 3 and Figure 11 As shown, as a preferred embodiment of the present invention, four stabilizing mechanisms 800 are vertically symmetrically arranged on the connecting plate 610, and the four stabilizing mechanisms 800 are all located on the outside of the upper mold 700. The stabilizing mechanisms 800 can work synchronously with the hydraulic system 600, and the bottom of the stabilizing mechanism 800 in the initial state is lower than the bottom of the upper mold 700. In this way, when the hydraulic system 600 drives the upper mold 700 and the stabilizing mechanism 800 to move downward synchronously, the stabilizing mechanism 800 can first contact the upper surface of the hatch cover, thereby completing the pre-fixation of the hatch cover, which helps to stabilize the position of the hatch cover before stamping and prevent the hatch cover from shifting during the mold pressing process, thereby improving the stamping accuracy; at the same time, the stabilizing mechanism 800 can complete the clamping and fixation of the upper and lower surfaces of the hatch cover by cooperating with the adsorption positioning mechanism 500, ensuring that the hatch cover is always stably fixed during the stamping process, thereby improving the stamping accuracy of the hatch cover.

[0050] The stabilizing mechanism 800 includes a stud 810, a stabilizing plate 820 and a spring 830. The stud 810 is distributed on the four corners of the connecting plate 610 and is vertically slidably connected thereto. The bottom of the stud 810 is fixed with a stabilizing plate 820. The bottom of the stabilizing plate 820 in the initial state is lower than the bottom of the upper mold 700. The top of the stabilizing plate 820 is connected to the bottom of the connecting plate 610 through a spring 830.

[0051] When the hydraulic system 600 drives the connecting plate 610 downward, the connecting plate 610 drives the stabilizing mechanism 800 and the upper die 700 to move downward synchronously. The stabilizing plate 820 on the stabilizing mechanism 800 can contact the hatch cover before the upper die 700, thereby completing the pre-fixation of the hatch cover. This helps to stabilize the position of the hatch cover before stamping and prevent the hatch cover from shifting during the downward pressing process of the die, thereby improving stamping accuracy.

[0052] The four stabilizing mechanisms 800 can be elastically extended and retracted individually, so that they can adapt to the ups and downs of the product surface while moving downward synchronously with the connecting plate 610, ensuring that each stabilizing plate 820 can fully contact the surface of the hatch cover and provide stable pressure. Compared with the interconnected pressure block system, this design can better fit the uneven surface, improve the fixing effect, and further ensure the stability of the hatch cover during the stamping process; at the same time, due to the independence of the four stabilizing mechanisms 800, when one of the stabilizing mechanisms 800 fails, it will not affect the normal operation of other stabilizing mechanisms 800, thereby improving the fault tolerance of the entire device and ensuring that in the event of failure of some stabilizing mechanisms 800, the hatch cover can still be fixed and stamped to a certain extent, reducing production interruptions caused by the failure of a single stabilizing mechanism 800.

[0053] In a preferred embodiment, one or more layers of concave-convex pads are installed at the bottom of the stabilizing plate 820. The concave-convex pads can not only improve the friction between the stabilizing plate 820 and the outer surface of the hatch cover, thereby improving the pressing efficiency and pressing quality of the stabilizing plate 820 on the hatch cover and improving the stamping accuracy of the hatch cover; it can also prevent the stabilizing plate 820 from causing additional damage to the outer surface of the hatch cover, ensure the integrity of the overall appearance of the hatch cover, and improve the processing efficiency and quality of the hatch cover.

[0054] The working principle of the present invention is:

[0055] For punching of non-magnetic hatch covers, before punching, the positioning mark is coated on the hatch cover at the position where the hole is to be punched, so that the staff or the robot can quickly complete the positioning of the hatch cover; when the hatch cover is placed on the stamping seat 300, the electromagnetic induction coil 940 is energized and generates an induced magnetic field at the upper mold 700. The positioning mark will generate an induced current under the action of the induced magnetic field and generate a secondary magnetic field. At this time, the electromagnetic induction coil 940 detects the change in the secondary magnetic field and converts the magnetic field change into an electrical signal through the electromagnetic induction principle. The control system converts the electrical signal transmitted by the electromagnetic induction coil 940 into a digital signal, and uses its internal preset mathematical model to accurately calculate the coordinate position of the positioning mark, and transmits the coordinate information to the control console 20 in a timely manner. 0, so that the staff can quickly know the position information of the hatch cover on the stamping seat 300, reducing positioning time and improving production efficiency; compared with traditional manual positioning or positioning methods relying on visual recognition, the time of each work cycle is greatly shortened, which is particularly suitable for batch production scenarios; and this positioning method based on the principle of electromagnetic induction is not affected by factors such as light, hatch cover surface color or material, can work stably in complex industrial environments, and provide high positioning accuracy, meeting the strict requirements of hatch cover stamping for position accuracy. Its characteristic of not being disturbed by external environmental factors enables it to maintain stable positioning performance under different production conditions, effectively improving the accuracy of hatch cover stamping position, thereby improving product quality;

[0056] The sliding seat 510 can slide to any position of the stamping seat 300, so that the adsorption component 540 can effectively and fully complete the adsorption of the bottom end surface of the hatch cover. The screw sleeve 523 can drive the lifting block 530 to move vertically by rotating on the screw rod 522, thereby changing the adsorption height of the lifting block 530 and the adsorption component 540, so that the adsorption component 540 can fully and effectively fit with the bottom end surface of the hatch cover, thereby completing the fixation of the hatch cover, and completing the precise positioning of the hatch cover by cooperating with the electromagnetic positioning mechanism 900, ensuring that the hatch cover is in the best positioning state before stamping; the sliding ball 543 can arbitrarily change the direction of the suction nozzle 545 by rotating in the sliding cavity 542, so that the suction nozzle 545 can be rotated to a position directly opposite to the hatch cover, ensuring the fit between the two, and then making the suction pump pass through the connection The coupling hose 546 and the adsorption tube 544 cooperate to achieve effective adsorption of the suction nozzle 545 and the bottom end surface of the hatch cover, thereby improving the adsorption stability between the suction nozzle 545 and the hatch cover, thereby completing the positioning and adsorption of hatch covers of different specifications and sizes; the locking screw 549 rotates to interfere with the surface of the sliding ball 543, thereby completing the restriction of the sliding ball 543, so that the sliding ball 543 can be stationary in the sliding cavity 542, thereby further improving the adsorption stability between the suction nozzle 545 and the hatch cover, ensuring that the hatch cover is in the best positioning state before stamping; and according to hatch covers of different shapes and sizes, the position and number of the adsorption positioning mechanism 500 on the stamping seat 300 can be flexibly adjusted to meet diverse product requirements, and can be applied to the stamping positioning of various types of hatch covers, thereby improving the versatility and applicability of the equipment;

[0057] When the hydraulic system 600 drives the connecting plate 610 downward, the connecting plate 610 drives the stabilizing mechanism 800 and the upper die 700 to move downward synchronously. The stabilizing plate 820 on the stabilizing mechanism 800 can contact the hatch cover before the upper die 700, thereby completing the pre-fixation of the hatch cover. This helps to stabilize the position of the hatch cover before stamping and prevent the hatch cover from shifting during the downward pressing process of the die, thereby improving stamping accuracy.

[0058] The four stabilizing mechanisms 800 can independently and elastically expand and contract, allowing them to adapt to the unevenness of the product surface as they move downward synchronously with the connecting plate 610, ensuring that each stabilizing plate 820 can fully contact the hatch cover surface and provide stable pressure. Compared with an interconnected pressure block system, this design can better conform to uneven surfaces, improve the fixing effect, and further ensure the stability of the hatch cover during the stamping process. At the same time, due to the independence of the four stabilizing mechanisms 800, if one stabilizing mechanism 800 fails, the normal operation of the other stabilizing mechanisms 800 will not be affected, thereby improving the fault tolerance of the entire device. Even if some stabilizing mechanisms 800 fail, the hatch cover can still be fixed and stamped to a certain extent, reducing production interruptions caused by the failure of a single stabilizing mechanism 800.

[0059] The above is the working principle of the hatch cover edge positioning punching device.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
