[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0020] In the description of the present invention, it should be understood that terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.
[0021] like Figures 1-6As shown, the stamping device proposed in this embodiment includes a stamping machine 100 and a feeding assembly 200, wherein the stamping machine 100 is used to perform stamping processing on the elevator door panel, and the feeding assembly 200 is used to transport the elevator door panel to be processed to the stamping area of the stamping machine 100, and transport the workpiece out of the stamping machine 100 after the stamping is completed. The feeding assembly 200 is electrically connected to the stamping machine 100, can receive the feedback signal of the stamping machine 100, and adjust its own conveying speed and positioning accuracy according to the returned data, so as to ensure that the elevator door panel can be accurately fed into the stamping position, thereby improving the stamping accuracy and processing quality.
[0022] The stamping machine 100 includes a PLC controller 107 and a workbench 103. The PLC controller 107 is arranged on the stamping machine 100. A first rangefinder 109 and a second rangefinder 110 are respectively provided at both ends of the workbench 103. The first rangefinder 109 and the second rangefinder 110 are configured to detect the position of the elevator door panel. The first rangefinder 109 and the second rangefinder 110 are both electrically connected to the PLC controller 107. At the same time, the PLC controller 107 is electrically connected to the feeding assembly 200. The first rangefinder 109 and the second rangefinder 110 output signals to the PLC controller 107, which can not only detect whether the elevator door panel is in place, but also detect the distance between the first rangefinder 109 and the elevator door panel. Combined with the preset distance between the first rangefinder 109 and the workbench 103, the feeding assembly 200 is controlled by the PLC controller 107 to place the elevator door panel stably on the workbench 103, thereby improving the automation level and stability of the stamping operation.
[0023] In this embodiment, the feeding assembly 200 is responsible for transporting the unstamped elevator door panel from the side where the first rangefinder 109 is located to the workbench 103 to achieve precise positioning. When in use, the feeding assembly 200 drives the elevator door panel to move. When the elevator door panel passes through the detection range of the first rangefinder 109, the first rangefinder 109 starts to output real-time distance data and transmits it to the PLC controller 107. At this time, the PLC controller 107 controls the feeding assembly 200 to move the elevator door panel toward the workbench 103. At the same time, the first rangefinder 109 continuously monitors the distance between the first rangefinder 109 and the elevator door panel. When the distance reading between the first rangefinder 109 and the elevator door panel is equal to the preset distance between the first rangefinder 109 and the workbench 103, it indicates that the elevator door panel has contacted the workbench 103, which is vertically in place.
[0024] While the feeding assembly 200 drives the elevator door panel to move vertically toward the workbench 103, the feeding assembly 200 also drives the elevator door panel to move horizontally toward the workbench 103. When the reading of the first rangefinder 109 suddenly decreases for the first time, it indicates that the elevator door panel begins to move above the workbench 103. When the reading of the first rangefinder 109 steadily decreases, it indicates that the elevator door panel is moving vertically toward the workbench 103. When the reading of the first rangefinder 109 suddenly increases again, it indicates that the elevator door panel has completely passed the first rangefinder 109 and entered the stamping position. This is horizontal positioning. The feeding assembly 200 is controlled by the PLC controller 107 so that the vertical and horizontal positioning of the elevator door panel are achieved at the same time. At this time, the stamping operation can be performed.
[0025] After the stamping work is completed, the feeding assembly 200 moves the processed elevator door panel out of the workbench 103 in the direction of the second rangefinder 110 in the reverse order; this process is similar to the working mode of the first rangefinder 109. When the elevator door panel gradually leaves the workbench 103 and enters the detection range of the second rangefinder 110, the second rangefinder 110 begins to monitor the position change of the elevator door panel and controls the feeding assembly 200 to gradually move the elevator door panel out of the stamping area, completing the entire automated process of feeding and discharging.
[0026] The feeding assembly 200 proposed in this embodiment realizes the precise movement of the elevator door panel in the vertical and horizontal directions through the combination of the elevator 201 and the feeding track 202; the feeding track 202 is provided with a feeding screw 203 and a screw motor 206, and the screw motor 206 drives the elevator 201 to slide on the feeding track 202 through the feeding screw 203, thereby realizing the precise positioning and transportation of the elevator door panel; the elevator 201 is responsible for driving the elevator door panel to move in the vertical direction, and the screw motor 206 controls the elevator 201 to move in the horizontal direction on the feeding track 202 by driving the rotation of the feeding screw 203.
[0027] In actual application, the PLC controller 107 precisely controls the elevator 201 and the screw motor 206, and ensures that the elevator door panel can accurately stay at the set stamping position by monitoring the position of the elevator door panel in real time; when the elevator door panel is placed on the elevator 201, the elevator 201 completes the vertical movement of the elevator door panel to ensure that the door panel is vertically aligned with the stamping table. At the same time, the screw motor 206 drives the elevator 201 to translate horizontally through the feeding screw 203, and accurately feeds the elevator door panel into the stamping position, realizing the automation and precise feeding of the elevator door panel, thereby improving production efficiency and precision.
[0028] Compared with traditional feeding devices, this embodiment has higher flexibility and adaptability, and can effectively meet the feeding requirements of elevator door panels of different sizes.
[0029] The stamping machine 100 proposed in this embodiment includes a stamping machine frame 101, and a slider 105 is provided on the stamping machine frame 101. The slider 105 is slidably connected to the stamping machine frame 101 through a sliding connection device. A punch 106 is provided on the slider 105, and the punch 106 can move up and down in the vertical direction under the drive of the slider 105; in this embodiment, a PLC controller 107 is fixed on the slider 105, and the PLC controller 107 is used to control the up and down movement of the punch 106, thereby realizing precise positioning and stamping force control during the stamping process.
[0030] A stamping die 108 is provided on the workbench 103, and the position of the punch 106 and the position of the stamping die 108 completely correspond in the vertical direction, ensuring that the punch 106 can accurately cooperate with the stamping die 108 during the stamping process. The PLC controller 107 controls the movement of the slider 105 to achieve precise control of the punch 106, ensure the accuracy of the stamping position, and ensure that the elevator door panel is stably and accurately subjected to the impact force during the stamping process, thereby improving the stamping accuracy and production efficiency.
[0031] At the same time, through the control of the PLC controller 107, the stamping parameters can be automatically adjusted according to different production requirements, thereby improving the stability of the production line and the overall work efficiency.
[0032] The stamping frame 101 proposed in this embodiment is provided with a hydraulic drive mechanism 102 and a stamping guide rail 104, the slider 105 is slidably connected to the stamping guide rail 104, the hydraulic drive mechanism 102 is fixedly connected to the slider 105, and the hydraulic drive mechanism 102 is configured to drive the slider 105 to rise and fall on the stamping guide rail 104. The design of the hydraulic drive mechanism 102 enables the slider 105 to move up and down smoothly and accurately on the guide rail 104, thereby completing the stamping operation of the elevator door panel.
[0033] The hydraulic drive mechanism 102 provides stable power through the hydraulic system, which can achieve high-precision control and ensure that the punch 106 can move up and down within the specified trajectory. The hydraulic drive mechanism 102 has a high power output capacity and can cope with stamping tasks with large workloads. It is especially suitable for use in large-scale production environments.
[0034] The sliding connection between the slider 105 and the stamping guide rail 104 ensures that the slider 105 moves smoothly and without offset, thereby avoiding the uneven stamping phenomenon that may occur during the stamping process and ensuring the accuracy of each stamping. In addition, the configuration of the hydraulic drive mechanism 102 also makes the speed and force of the stamping process easier to adjust, and can be optimized and adjusted according to the specific requirements of different materials and elevator door panels, thereby improving production efficiency and stamping accuracy.
[0035] The elevator 201 of this embodiment is provided with a telescopic head 204, which is rotatably connected to the elevator 201 and has a variable length. A door panel clamp 205 is provided on the telescopic head 204. The door panel clamp 205 is configured to move the elevator door panel, ensuring that the elevator door panel can be accurately clamped and moved to the stamping position on the workbench 103 during the stamping process.
[0036] The telescopic function of the telescopic head 204 enables it to adjust its length as needed to adapt to elevator door panels of different sizes. The door panel clamp 205 is configured on the telescopic head 204 and is specifically used to clamp and fix the elevator door panel to ensure that the elevator door panel is stable and motionless during the stamping process, avoiding accuracy deviation caused by loosening.
[0037] During use, when the telescopic head 204 is positioned above the elevator door panel workbench 103, the telescopic head 204 rotates outward to avoid interference with the punch 106, which can effectively avoid collision between the telescopic head 204 and the punch 106 during the stamping process, thereby ensuring the smooth progress of the stamping process.
[0038] While improving stamping accuracy, it also optimizes the space utilization of the stamping machine, avoids unnecessary structural interference, and makes the entire stamping process simpler, more efficient and safer.
[0039] The stamping fixture proposed in this embodiment also includes a stacking table 300, which includes a lifting plate 301 and a compression spring 302. The lifting plate 301 is arranged on the compression spring 302, and the compression spring 302 is arranged on the stamping machine table 100. The lifting plate 301 is located on both sides of the workbench 103. The lifting plates 301 on both sides of the workbench 103 are respectively used to place the elevator door panels before and after stamping.
[0040] Since the compression spring 302 can be extended and retracted, when the elevator door panel on the lifting plate 301 is reduced, the pressure on the compression spring 302 gradually decreases, and the compression spring 302 can gradually extend to lift the lifting plate 301 and the elevator door panel on the lifting plate 301. By utilizing the elastic characteristics of the compression spring 302, the position of the lifting plate 301 is automatically adjusted when the elevator door panel is reduced, ensuring that the lifting plate is always at an appropriate height so that the door panel clamp 205 can smoothly clamp the elevator door panel.
[0041] The use of compression spring 302 enables the stacking platform 300 to automatically adjust the height of the lifting plate according to the number of elevator door panels without the need for additional power drive, avoiding the difficulty of clamping caused by the stacking platform being too high or too low, and improving the efficiency and accuracy of the stamping process.
[0042] The door panel clamp 205 proposed in this embodiment is a vacuum suction cup clamp. The working principle of the vacuum suction cup clamp is to create negative pressure inside the suction cup to form a strong adsorption force with the surface of the elevator door panel. The adsorption force is evenly distributed on the surface of the elevator door panel, reducing the common problem of local excessive clamping of mechanical clamps and avoiding deformation of the door panel due to excessive clamping.
[0043] In addition, the vacuum suction cup fixture has the characteristics of quick installation and release. The vacuum suction cup can quickly absorb the elevator door panel and clamp it stably, which improves the level of automation. Especially in high-frequency production environments, the vacuum suction cup fixture can significantly improve production efficiency.
[0044] During actual use, the vacuum suction cup fixture can instantly absorb the door panel, ensuring that the elevator door panel enters the stamping position quickly and stably.
[0045] The vacuum suction cup fixture proposed in this embodiment is suitable for weakly magnetic or non-magnetic materials such as aluminum alloy elevator door panels and composite elevator door panels.
[0046] In another embodiment of the present invention, the door panel clamp 205 is an electromagnetic clamp. The working principle of the electromagnetic clamp is to control the clamping and release of the elevator door panel by activating and de-energizing the electromagnet. The control of the electromagnetic clamp is very simple, and the precise operation of the electromagnetic clamp can be achieved through a PLC controller or an automation system. For elevator door panels with complex shapes or large sizes, the electromagnetic clamp can provide stable and reliable clamping force.
[0047] The door panel clamp 205 proposed in another embodiment of the present invention is an electromagnetic clamp, which is suitable for magnetic metal materials such as traditional steel elevator door panels.
