Description

Technical Field

[0001] The utility model relates to the field of lead ingot production, in particular to a lead ingot cold pressing and shaping machine. Background Art

[0002] In the production process of lead ingots, most of the lead ingots are in the shape of long strips with protruding ears on both sides. The protruding ears facilitate the transportation of the lead ingots by forklifts. Two bundling grooves are provided at the bottom of the lead ingots for the convenience of bundling the lead ingots. The lead ingots integrally formed on the production line are in the shape of rectangular parallelepiped without protruding ears and bundling grooves. The protruding ears are for the convenience of later forklift transportation, and the bundling grooves are for the convenience of later bundling. In the existing technology, the lead ingots are cut to form the protruding ears and bundling grooves. The weight of the cut lead accounts for about 5% of the entire lead ingot. The cut lead needs to be re-smelted and re-produced into lead ingots, which not only increases the workload in the production process, but also causes certain losses in cutting. Therefore, there is an urgent need for a lead ingot cold pressing and shaping machine that can press out the protruding ears on both sides of the lead ingot and the bundling grooves at the bottom of the lead ingot while reducing the change in the weight of the lead ingot, thereby saving production costs and improving production efficiency.

[0028] like Figure 1-3As shown, a lead ingot cold pressing and shaping machine includes a bracket 1 and a machine platform 2. The bracket is arranged above the machine platform, and a hydraulic press 3 is provided on the bracket. The hydraulic press is connected to an upper mold 4. A lower mold 5 is provided on the machine platform, and the lower mold is arranged below the upper mold. First protrusions 501 are symmetrically provided at both ends of the lower mold, and the two first protrusions are used to press out the protruding ear portions 18 on both sides of the lead ingot. Second protrusions 502 are symmetrically provided in the middle of the lower mold, and the two second protrusions are symmetrically provided between the two first protrusions. The two second protrusions are used to press out the bundling grooves 19 at the bottom of the lead ingot. A moving mechanism is also provided on the side of the machine platform, and a lead feed conveyor belt (not shown in the figure) and a lead discharge conveyor belt (not shown in the figure) are respectively provided at both ends of the machine platform. The setting directions of the lead feed conveyor belt, the lead discharge conveyor belt and the moving mechanism are consistent. The lead feed conveyor belt conveys the lead ingot to be press-processed to the moving mechanism. The moving mechanism can transport the lead ingot on the lead feed conveyor belt to the machine platform, so as to facilitate the hydraulic press to press the lead ingot. The press-processed lead ingot is transported to the lead discharge conveyor belt via the moving mechanism.

[0029] The moving mechanism includes two first cylinders 9 symmetrically arranged on both sides of the lead inlet conveyor belt and two second cylinders 20 symmetrically arranged on both sides of the lead outlet conveyor belt. The upper ends of the two first cylinders and the second cylinders are provided with first slide rails 8, and a moving frame 6 is slidably connected in the first slide rails on the same side. The number of first slide rails in this embodiment is four, and a moving frame is slidably connected in the two first slide rails located on the same side of the machine. The moving frames are symmetrically arranged relative to the machine. One end of the two moving frames is connected by a connecting frame 10, and the two sides of the connecting frame are connected to the moving frame by two connecting blocks 11. The two connecting blocks are provided with second slide rails 12 in the vertical direction. One end of the two moving frames is slidably connected to the second slide rail. Three groups of brackets 7 are symmetrically provided on the side of the two moving frames close to the machine. The two moving frames can slide in the two first slide rails respectively. Each first cylinder and second cylinder is provided with a cylinder base (not shown in the figure) at the lower end, and a cylinder slide rail (not shown in the figure) is provided under each cylinder base. Each cylinder base is slidably connected to the cylinder slide rail, and each cylinder base is provided with a drive motor for driving the cylinder base to slide. The two connecting blocks are provided with a third slide rail in the horizontal direction, and the connecting frame is slidably connected to the third slide rail. The connecting frame can slide within the two third slide rails, and the cylinder base slides, thereby driving the mobile frame to move. One end of the mobile frame slides along the third slide rail, thereby adjusting the distance between the two mobile frames. The three groups of brackets are evenly spaced and arranged on the inner side of the two mobile frames. The evenly spaced brackets can ensure the stable operation of the device. Each time the mobile frame lifts three lead ingots and transports three lead ingots, the distance between the two brackets is the same. The connecting frame is connected to a transmission screw 14 that can drive the connecting frame to move. The inside of the connecting frame is provided with an internal thread that works with the transmission screw. The connecting frame is driven to move by the rotation of the transmission screw. The transmission screw is connected to a screw motor 15. A sliding platform is provided under the connecting frame. The sliding platform is provided with a fourth slide rail (not shown in the figure). The lower end of the connecting frame is slidably connected to the fourth slide rail. The transmission screw drives the connecting frame to move along the conveying direction of the lead feed conveyor belt in the fourth slide, thereby driving the entire moving mechanism to move through the two connecting blocks. The height of the sliding platform is lower than the height of the machine. The connecting frame is arranged below the lead discharge conveyor belt, which is convenient for the moving mechanism to convey the lead ingots to the lead discharge conveyor belt.

[0030] A lead blocking mechanism 17 is provided on the side of the machine near the lead inlet conveyor belt. The lead blocking mechanism is L-shaped, and one side of the L-shaped opening of the lead blocking mechanism faces the lead inlet conveyor belt, which is convenient for the lead ingot to enter the lead blocking mechanism. A photoelectric sensor is provided at the lower end of the lead blocking mechanism to detect whether there is a lead ingot in the lead blocking mechanism. The lead blocking mechanism can block the lead ingot on the lead blocking mechanism to keep the lead ingot stable, which is convenient for the lead moving device to move the lead ingot to the machine for pressure processing. A temporary storage rack 16 is provided on the side of the machine near the lead outlet conveyor belt. The temporary storage rack is used to temporarily place the lead ingots that have undergone pressure processing. The operator can observe whether the lead ingots are qualified on the temporary storage rack. Burrs and other problems generated during the pressure processing can be quickly processed to ensure the product quality of the lead ingots. A third cylinder is provided on the lower mold. The third cylinder is located between the two second protrusions. The third cylinder is used to push the lead ingots that have undergone pressure processing upward to prevent the lead ingots from sticking to the lower mold. Figure 1 This is the front view of the device. Figure 2 This is the rear view of the device.

[0031] like Figure 4-5 As shown, each bracket includes a mounting base 701 and two supporting legs 702, a waist hole 704 is provided on the mounting base, and a mounting hole of the same size as the waist hole is provided on the movable frame. Each supporting leg is installed on the mounting base by a bolt 703 passing through the waist hole and the mounting hole in sequence. The screw part in the bolt can move in the waist hole, so that the distance between the two supporting legs can be adjusted to accommodate lead ingots of different widths. The inner sides of adjacent supporting legs in each bracket are tilted, which can enable the lead ingot to fall into the bracket to prevent the lead ingot from falling from the bracket during movement. In this embodiment, a photoelectric sensor is provided on the inner side of each group of brackets, and the photoelectric sensor is used to detect whether there is a lead ingot on the bracket.

[0032] like Figure 6-7 As shown, Figure 6 Lead ingots before pressure processing are not easy to transport by forklift and are not easy to bundle. Figure 7 For lead ingots that have undergone pressure processing, the protruding ears on both sides are used to facilitate transportation by vehicles, and the two bundling grooves in the middle are convenient for operators to bundle the lead ingots.

[0033] How it works

[0034] The lead ingot is transported to the lead blocking mechanism by the lead feeding conveyor belt, and the movable rack is in the initial position. The brackets on the two movable racks close to the lead feeding conveyor belt are located directly below the lead ingot. The lead blocking mechanism blocks the lead ingot to keep the lead ingot stable. The height of the upper end of the bracket is lower than the height of the bottom end of the lead ingot. The two brackets approach the lead ingot. When the distance between the two brackets is enough to lift the lead ingot, the first cylinder and the second cylinder rise at the same time, driving the two movable racks to rise, and the bracket lifts the lead ingot. After that, the screw motor starts, and the screw motor drives the connecting rack to move, and the connecting rack drives the movable rack to move, transporting the lead ingot to the top of the lower mold. The first cylinder and the second cylinder descend at the same time, leaving the lead ingot on the lower mold, and the two movable racks then move away from the lead ingot, and the movable rack returns to the initial position. During the movement of the movable frame to the initial position, the hydraulic press drives the upper mold to move downward to perform pressure processing on the lead ingot on the lower mold. After the pressure processing, the third cylinder pushes up to prevent the lead ingot from sticking to the lower mold. The movable frame continues to move from the initial position, and the movable frame rises. The middle bracket on the movable frame moves the lead ingot after pressure processing to the temporary storage rack. The bracket on the movable frame close to the lead inlet conveyor belt lifts the lead ingot that has not been pressure processed. The moving action of the movable frame is repeated in this way to move the lead ingot at the lead blocking mechanism to the lower mold for pressure processing. After the pressure processing, the middle bracket on the movable frame moves the lead ingot to the temporary storage rack. The moving action of the movable frame is repeated again, and the bracket close to the lead outlet conveyor belt moves the lead ingot to the lead outlet conveyor belt.
