Description

Technical Field

[0001] The utility model relates to the technical field of plate casting machines, in particular to a shaping device for plate casting machines. Background Art

[0002] The plate casting machines widely used in the market currently include a high-level lead melting furnace (or a low-level lead melting furnace), a lead valve device, a lead spoon pouring mechanism, a mold opening and closing mechanism, a shaping and conveying mechanism, a grid horizontal positioning mechanism, a flat-cutting knife mold, a grid collecting mechanism and a circulating water tank.

[0003] Publication (announcement) No.: CN102909351A discloses a flat-cutting plate casting machine, which includes a high-position lead melting furnace, a series lead valve device, a lead spoon lead pouring mechanism, a mold opening and closing mechanism, a shaping and conveying mechanism, a grid horizontal positioning mechanism, a flat-cutting knife mold, a grid leveling and weighing mechanism, a grid sheet collecting mechanism, and a circulating water tank, which are connected in sequence to form an assembly line device, and the device works in a coordinated manner under automatic electrical control.

[0004] Although the above scheme realizes the automatic casting, compaction molding and automatic weighing and screening of lead alloy grids, its leveling mechanism is a hydraulic drive device that drives the leveling plate to press down to flatten the grid below. Although this leveling mechanism can facilitate the compression of the plate, if the lower pressure plate wears during use, the plate cannot be placed horizontally when placed on the lower pressure plate, which will result in poor flattening effect and damage to the plate. Utility Model Content

[0005] The main purpose of the utility model is to provide a casting machine shaping device, which solves the problem that if the lower pressure plate is worn during use, the plate cannot be placed horizontally when placed on the lower pressure plate, which will lead to poor flattening effect and damage to the plate.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A plate casting machine shaping device comprises a workbench and a mounting frame fixedly connected to the top of the workbench, a shaping mechanism arranged at the bottom of the mounting frame, and a detection mechanism arranged at the top of the workbench;

[0008] The shaping mechanism includes an electric push rod fixedly connected to the bottom of the mounting frame, an upper pressing plate fixedly connected to the output end of the electric push rod, and a lower pressing plate arranged directly below the upper pressing plate for carrying the plate to be processed;

[0009] The detection mechanism comprises an infrared transmitter and an infrared receiver which are movably arranged on the top of the workbench and are used to detect the flatness of the upper surface of the lower pressing plate.

[0010] Preferably, the shaping mechanism further includes a placement groove opened at the top of the workbench, a through hole opened at the center of the bottom of the placement groove, and a hydraulic cylinder fixedly connected to the bottom of the workbench.

[0011] Preferably, the shaping mechanism further includes an electromagnet embedded in the workbench, a spring groove opened on the inner side wall of the placement groove, a connecting spring fixedly connected to the bottom of the spring groove, a locking block fixedly connected to the end face of the connecting spring, and a locking groove opened on the outer side wall of the lower pressing plate.

[0012] Preferably, there are two sets of the overall structures composed of the electromagnet, the spring groove, the connecting spring, the locking block, and the locking groove, and the two sets of the overall structures are symmetrically arranged with respect to the central vertical plane of the lower pressing plate.

[0013] Preferably, the detection mechanism further includes a movable frame movably arranged on the top of the workbench, a servo motor fixedly connected to the top of the workbench, and a lead screw fixedly connected to the output end of the servo motor.

[0014] Preferably, the movable frame is in the shape of "冂", and a guiding hole is penetrated through the outer side wall of the vertical plate of the movable frame, and a limiting rod is fixedly connected to the top of the workbench, and the limiting rod penetrates through the movable frame through the guiding hole.

[0015] Preferably, the detection mechanism further includes a driving motor fixedly connected to the outer side wall of the movable frame, and a cleaning roller fixedly connected to the output end of the driving motor.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. In the utility model, when the electromagnet is powered off, the electromagnet will lose its magnetic force, so that the connecting spring pushes the locking block to move until one end of the locking block is completely inserted into the locking groove, realizing the fixation of the lower pressing plate. Then, the plate to be processed can be placed on the top of the lower pressing plate, and by starting the electric push rod to descend, the upper pressing plate is driven to descend, so that the upper pressing plate and the lower pressing plate are used to extrude and shape the plate.

[0018] 2. In the utility model, by starting the servo motor, the servo motor drives the lead screw to rotate, and then drives the movable frame to move in a straight line. At this time, the driving motor is in a working state, driving the cleaning roller to rotate, so as to clean the lower pressing plate. During this process, the infrared emitter is in a working state. When the infrared receiver can receive the signal emitted by the infrared emitter, it means that the lower pressing plate is in a horizontal state. Otherwise, the lower pressing plate needs to be replaced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] Embodiment 1: Figure 1-5 As shown, a plate casting machine shaping device comprises a workbench 1, and a mounting frame 2 fixedly connected to the top of the workbench 1, a shaping mechanism arranged at the bottom of the mounting frame 2, and a detection mechanism arranged at the top of the workbench 1;

[0027] The shaping mechanism includes an electric push rod 301 fixedly connected to the bottom of the mounting frame 2, an upper pressing plate 302 fixedly connected to the output end of the electric push rod 301, and a lower pressing plate 303 arranged directly below the upper pressing plate 302 for carrying the plate to be processed;

[0028] The detection mechanism includes an infrared transmitter 407 and an infrared receiver 408 movably disposed on the top of the workbench 1 for detecting the flatness of the upper surface of the lower pressing plate 303 .

[0029] The shaping mechanism also includes a placement groove opened on the top of the workbench 1, a through hole opened at the center of the bottom of the placement groove, and a hydraulic cylinder 304 fixedly connected to the bottom of the workbench 1, wherein the output end of the hydraulic cylinder 304 extends to the interior of the placement groove through the through hole, and the cross-section of the placement groove matches the cross-section of the lower pressure plate 303.

[0030] The shaping mechanism also includes an electromagnet 305 embedded in the workbench 1, a spring groove opened on the inner wall of the placement groove, a connecting spring 306 fixedly connected to the bottom of the spring groove, a locking block 307 fixedly connected to the end face of the connecting spring 306, and a locking groove opened on the outer wall of the lower pressure plate 303, wherein the locking block 307 is made of ferromagnetic material, and the longitudinal section of the locking block 307 matches the longitudinal section of the locking groove.

[0031] There are two groups of integral structures consisting of the electromagnet 305 , the spring slot, the connecting spring 306 , the locking block 307 , and the locking slot. The two groups of integral structures are symmetrically arranged about the mid-vertical plane of the lower pressure plate 303 .

[0032] By placing the lower pressure plate 303 in the placement groove, the opening of the locking groove will be opposite to the spring groove, and then by cutting off the power to the electromagnet 305, the electromagnet 305 will lose its magnetic force, so that the connecting spring 306 pushes the locking block 307 to move until one end of the locking block 307 is completely inserted into the interior of the locking groove, thereby fixing the lower pressure plate 303. After that, the plate to be processed can be placed on the top of the lower pressure plate 303, and by starting the electric push rod 301 to descend, the upper pressure plate 302 is driven to descend, so that the upper pressure plate 302 and the lower pressure plate 303 are pressed and shaped.

[0033] Embodiment 2: Figure 1-5 As shown, a plate casting machine shaping device comprises a workbench 1, and a mounting frame 2 fixedly connected to the top of the workbench 1, a shaping mechanism arranged at the bottom of the mounting frame 2, and a detection mechanism arranged at the top of the workbench 1;

[0034] The shaping mechanism includes an electric push rod 301 fixedly connected to the bottom of the mounting frame 2, an upper pressing plate 302 fixedly connected to the output end of the electric push rod 301, and a lower pressing plate 303 arranged directly below the upper pressing plate 302 for carrying the plate to be processed;

[0035] The detection mechanism includes an infrared transmitter 407 and an infrared receiver 408 movably disposed on the top of the workbench 1 for detecting the flatness of the upper surface of the lower pressing plate 303 .

[0036] The detection mechanism also includes a movable frame 401 movably arranged on the top of the workbench 1, a servo motor 402 fixedly connected to the top of the workbench 1, and a screw rod 403 fixedly connected to the output end of the servo motor 402, wherein the movable frame 401 is movably connected to the screw rod 403, and the movable frame 401 is driven to perform linear motion by the screw rod 403.

[0037] The movable frame 401 is in the shape of "冂", and a guide hole is penetrated through the outer side wall of the vertical plate of the movable frame 401. The top of the workbench 1 is fixedly connected to the limit rod 404, and the limit rod 404 penetrates through the movable frame 401 through the guide hole. Among them, the infrared emitter 407 and the infrared receiver 408 are fixedly connected to the opposite inner side walls of the movable frame 401, and their openings are arranged facing each other.

[0038] The detection mechanism further includes a driving motor 405 fixedly connected to the outer side wall of the movable frame 401, and a cleaning roller 406 fixedly connected to the output end of the driving motor 405. The bottom surface of the cleaning roller 406 is flush with the top surface of the lower pressing plate 303.

[0039] Before shaping the sheet material, by starting the servo motor 402, the servo motor 402 drives the lead screw 403 to rotate, and then drives the movable frame 401 to perform a linear motion. At this time, the driving motor 405 is in a working state, driving the cleaning roller 406 to rotate, so as to clean the lower pressing plate 303. And by whether the infrared receiver 408 can receive the signal emitted by the infrared emitter 407, it is judged whether the lower pressing plate 303 is in a horizontal position. That is, when the infrared receiver 408 can receive the signal emitted by the infrared emitter 407, it means that the lower pressing plate 303 is in a horizontal state. Otherwise, the lower pressing plate 303 needs to be replaced;

[0040] By energizing the electromagnet 305, the electromagnet 305 will have magnetic force at this time, so as to adsorb the locking block 307, so that the locking block 307 compresses the connecting spring 306 until the locking block 307 is completely located inside the spring groove. Then, by starting the hydraulic cylinder 304, it is pushed to move the lower pressing plate 303 upward, so that the lower pressing plate 303 can be replaced.
