[0004] The ingot removal rod is clearance-fitted with the sliding bearing and interference-fitted with the dust cover, allowing the ingot removal rod to be positioned within the ingot removal seat via the dust cover. In the prior art, the ingot removal rod is very prone to damage, and when the ingot removal rod is damaged, the entire ingot removal system often needs to be replaced, resulting in high maintenance costs for ingot removal. Utility Model Content

[0005] The purpose of this invention is to provide a stamping device for disassembling and assembling ingots, which facilitates the easy disassembly of the ingot-removing rod and the ingot-removing seat, thereby making it convenient to replace the ingot-removing rod separately.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a stamping device for ingot removal and assembly, comprising a worktable, a stamping table on the worktable, a column on one side of the stamping table, a connecting plate on the upper end of the column, a stamping cylinder at one end of the connecting plate, a turntable rotatably connected to the stamping table, a plurality of material discharge ports evenly spaced along the turntable for the ingot removal rods to fall through, a storage box for storing the ingot removal rods on the lower side of the worktable, one side of the turntable suspended above the storage box, and a support sleeve on the turntable at the material discharge port, the upper surface of which is abutted by the hexagonal ring platform of the ingot removal seat.

[0007] A further feature of this invention is that a movable sleeve is provided on one side of the support sleeve, the side of the movable sleeve is hinged to the side of the upper end face of the support sleeve, and the movable sleeve has an inclined surface for the dust cover of the end of the spindle picker to abut against; when the movable sleeve rotates to the upper side of the support sleeve, the upper end face of the movable sleeve is abutted by the hexagonal ring platform of the spindle picker.

[0008] A further feature of this invention is that when the movable sleeve rotates to the upper side of the support sleeve and the upper end face of the movable sleeve is contacted by the hexagonal ring platform of the ingot-removing seat, the end of the ingot-removing rod is located on the inner side of the support sleeve.

[0009] A further feature of this invention is that: a central shaft rotatably connected to a stamping platform is provided at the center of the turntable, a driven gear is provided at the lower end of the central shaft, a servo motor is fixed on the lower side of the stamping platform, and a driving gear meshing with the driven gear is provided on the output shaft of the servo motor.

[0010] A further feature of this invention is that transparent plastic plates are provided at both the front and rear positions of the piston rod of the stamping cylinder.

[0011] A further feature of this invention is that a connecting rod is provided between the upper ends of the two transparent plastic plates, and a fixed arm connected to the connecting rod is provided on the lower side of the connecting plate.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. When it is necessary to remove the ingot-removing rod from the ingot-removing seat, place the ingot-removing rod upwards and embed the ingot-removing seat into the support sleeve. At this time, the hexagonal ring platform on the ingot-removing seat abuts against the upper end face of the support sleeve. By rotating the turntable and the operator picking up and placing the ingot-removing seats on the support sleeve one by one, when the support sleeve rotates to the position below the stamping cylinder, the piston rod of the stamping cylinder moves down and the end of the piston rod can press against the upper end of the ingot-removing rod. Then, the interference fit between the ingot-removing rod and the dust cover is broken, allowing the ingot-removing rod to detach from the underside of the ingot-removing seat. At the same time, when the turntable rotates to the suspended position above the storage box, the ingot-removing rod can fall down along the discharge port into the storage box, so that the disassembled ingot-removing rod can be stored in the storage box. Finally, the ingot-removing rod and the ingot-removing seat can be easily separated, making it convenient to replace the ingot-removing rod individually.

[0014] 2. When a new spindle picking rod needs to be installed on the spindle picking seat, rotate the movable sleeve on one side of the support sleeve upwards, so that the movable sleeve rotates to the upper side of the support sleeve. Then, insert one end of the dust cover of the spindle picking seat downwards into the movable sleeve, so that the dust cover is supported in the inclined part, and the hexagonal ring platform is supported at the upper end face of the movable sleeve. Then, insert the head end of the spindle picking rod downwards into the spindle picking seat, with the bevel gear at the end of the spindle picking rod facing upwards. When the support sleeve and the movable sleeve rotate to the position below the stamping cylinder, the piston rod of the stamping cylinder moves down and the end of the piston rod can press on the bevel gear of the spindle picking rod. Then, the spindle picking rod can be pushed into the dust cover, thereby realizing the interference fit between the spindle picking rod and the dust cover. Finally, the spindle picking rod and the spindle picking seat can be easily assembled, thus facilitating the replacement of the spindle picking rod.

[0015] 3. When the movable sleeve rotates to the upper side of the support sleeve and the upper end face of the movable sleeve is in contact with the hexagonal ring platform of the ingot picking seat, the end of the ingot picking rod is located inside the support sleeve, thereby avoiding interference between the end of the ingot picking rod and the stamping table after it passes through the material drop hole due to excessive length.

[0016] 4. When the turntable is rotating, the servo motor intermittently drives the drive gear to rotate, and then the drive gear drives the turntable to rotate intermittently through the driven gear, which facilitates continuous stamping operations on the turntable;

[0017] 5. When the piston rod of the stamping cylinder is performing the stamping operation up and down, the transparent plastic plates installed at both the front and rear positions of the piston rod can play a safety protection role, preventing the operator from being accidentally injured by the piston rod during operation.

[0018] 6. The two transparent plastic plates are connected by a connecting rod, and the connecting plate is fixed to the connecting rod by a fixing arm. Attached Figure Description

[0025] The technical solutions in the embodiments will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] A stamping device for ingot removal and assembly, as described in the following example. Figure 1 The stamping equipment for ingot removal and assembly includes a workbench 1, on which a stamping table 2 is fixed by bolts. A vertical column 21 is fixed to one side of the stamping table 2 by bolts. A connecting plate 22 is fixed to the upper end of the column 21 by bolts. A stamping cylinder 3 is fixed to one end of the connecting plate 22 by bolts. Transparent plastic plates 9 are provided at the front and rear positions of the piston rod of the stamping cylinder 3. A connecting rod 91 is fixed between the upper ends of the two transparent plastic plates 9. A fixed arm 221, which is fixedly connected to the connecting rod 91, is fixed to the lower side of the connecting plate 22 by bolts.

[0027] Reference Figure 1 , Figure 2 , Figure 3A turntable 4 is rotatably connected to the stamping table 2. A central shaft 42 is fixed at the center of the turntable 4 and is rotatably connected to the stamping table 2 via bearings. A driven gear 421 is fixed at the lower end of the central shaft 42. A servo motor 8 is fixed on the lower side of the stamping table 2. A drive gear 81 that meshes with the driven gear 421 is fixed on the output shaft of the servo motor 8. The turntable 4 has multiple dropping ports 41 that are evenly spaced along the turntable 4 for the stamped ingot picking rods 101 to fall. A storage box 5 for storing the ingot picking rods 101 is placed on the lower side of the worktable 1. One side of the turntable 4 is suspended above the storage box 5. A support sleeve 6 is welded on the turntable 4 at the dropping port 41. The upper end of the support sleeve 6 can be contacted by the hexagonal ring platform of the ingot picking seat 10.

[0028] Reference Figure 1 , Figure 3 , Figure 4 A movable sleeve 7 is also provided on one side of the support sleeve 6, and the side of the movable sleeve 7 is hinged to the side of the upper end face of the support sleeve 6. The movable sleeve 7 is integrally provided with a beveled part 71 for the dust cover 102 at the end of the ingot picking seat 10 to abut. When the movable sleeve 7 rotates to the upper side of the support sleeve 6, the upper end face of the movable sleeve 7 is abutted by the hexagonal ring platform of the ingot picking seat 10. At the same time, when the movable sleeve 7 rotates to the upper side of the support sleeve 6 and the upper end face of the movable sleeve 7 is abutted by the hexagonal ring platform of the ingot picking seat 10, the end of the ingot picking rod 101 is located inside the support sleeve 6.

[0029] Principle: When it is necessary to remove the ingot removal rod 101 from the ingot removal seat 10, the ingot removal rod 101 is positioned upwards and the ingot removal seat 10 is embedded in the support sleeve 6. At this time, the hexagonal ring platform on the ingot removal seat 10 abuts against the upper end surface of the support sleeve 6. The ingot removal seats 10 are then removed and placed on the support sleeve 6 one by one by the operator through the rotation of the turntable 4. When the support sleeve 6 rotates to the position below the stamping cylinder 3, the piston rod of the stamping cylinder 3 moves downwards, and the end of the piston rod presses against the upper end of the ingot removal rod 101. Then the interference fit between the ingot removal rod 101 and the dust cover 102 can be broken, allowing the ingot removal rod 101 to detach from the underside of the ingot removal seat 10. At the same time, when the turntable 4 rotates to the suspended position above the storage box 5, the ingot removal rod 101 can fall into the storage box 5 along the material drop port 41, thereby storing the disassembled ingot removal rod 101 through the storage box 5. Finally, the ingot removal rod 101 and the ingot removal seat 10 can be easily separated, making it convenient to replace the ingot removal rod 101 separately.

[0030] When a new spindle-removing rod 101 needs to be installed on the spindle-removing base 10, the movable sleeve 7 on one side of the support sleeve 6 is rotated upward, so that the movable sleeve 7 rotates to the upper side of the support sleeve 6. Then, one end of the dust cover 102 of the spindle-removing base 10 is inserted downward and rearward into the movable sleeve 7, so that the dust cover 102 is supported in the inclined surface 71, and the hexagonal ring platform is supported at the upper end face of the movable sleeve 7. Then, the head end of the spindle-removing rod 101 is inserted downward and rearward into the spindle-removing base 10, and the spindle-removing rod 101... With the bevel gear at the end of 01 facing upwards, when the support sleeve 6 and the movable sleeve 7 rotate to the position below the stamping cylinder 3, the piston rod of the stamping cylinder 3 moves down and the end of the piston rod can press on the bevel gear of the ingot removal rod 101. Then, the ingot removal rod 101 can be pushed into the dust cover, thereby realizing the interference fit between the ingot removal rod 101 and the dust cover. Finally, the ingot removal rod 101 and the ingot removal seat 10 can be easily assembled, thus facilitating the replacement of the ingot removal rod 101.
