Description

Technical Field

[0001] This application relates to the field of stamping equipment technology, and more specifically, to a sheet metal stamping device for appliance bases. Background Technology

[0002] The sheet metal stamping device for home appliance bases is an automated equipment specifically designed for producing bases for home appliances. It mainly applies high pressure to metal sheets through molds to complete processes such as punching and bending. It includes a drive structure, mold assembly, and control system.

[0003] In related technologies, to address the issues of manual loading and unloading and subsequent start / stop via switches, which is cumbersome and inefficient, and automatic machine start / stop requiring manual coordination with machine speed, which can easily lead to accidents and poses a safety hazard, a patent with publication number CN218835894U provides a stamping machine for producing sheet metal parts for small household appliances. This device uses an independent tray on the lower die, which can be attracted by a magnet when the upper die is raised, causing the steel ball to detach from the positioning groove. When the tray falls, the entire workpiece can slide out along the slope of the inclined groove, automatically delivering the workpiece without manual removal, saving time and effort and reducing danger. Furthermore, after the tray is removed, stamping can be paused by photoelectric sensing, and work can only resume after loading again, eliminating the need for manual start / stop, making it safer and more convenient.

[0004] Although the existing technical solution mentioned above can achieve the effect of automatically sending out the workpiece by setting a magnet to attract the back of the tray when the upper mold rises, after the tray is unloaded, it is necessary to wait for the tray to reset before the next piece of the appliance base sheet metal part can be placed, and then the sheet metal part can be stamped again, which affects the efficiency of the stamping device.

[0005] In view of this, we propose a sheet metal stamping device for appliance bases. Utility Model Content

Detailed Implementation

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] Reference Figure 1 and Figure 2 This application discloses a sheet metal stamping device for a home appliance base, including a stamping table 1. Columns 11 are fixedly installed on both sides of the top of the stamping table 1. A top plate 12 is fixedly installed on the top of each column 11. An upper mold 2 is installed at the bottom of the top plate 12. The upper mold 2 is raised and lowered under the drive of a hydraulic cylinder 5. An electromagnet 21 is installed at the bottom of the upper mold 2. A lower mold 3 is installed on the top of the stamping table 1. A receiving component 4 is installed between the upper mold 2 and the lower mold 3. The receiving component 4 receives and sends out the sheet metal part of the home appliance base under the drive of the hydraulic cylinder 5.

[0031] When the equipment is stamping the sheet metal parts of the appliance base, the upper mold 2 is driven to descend by the hydraulic cylinder 5. At the same time, the hydraulic cylinder 5 drives the receiving component 4 to open, so that the upper mold 2 and the lower mold 3 can cooperate to stamp the sheet metal parts of the appliance base. After stamping, the electromagnet 21 is activated to attract the stamped sheet metal parts and lift them up. During the lifting process, the hydraulic cylinder 5 drives the receiving component 4 to reset. After the sheet metal parts are raised to a position higher than the receiving component 4, the electromagnet 21 is turned off, causing the electromagnet 21 to lose its magnetism, so that the sheet metal parts fall to the top of the receiving component 4. During the next stamping, the hydraulic cylinder 5 drives the upper mold 2 to descend and drives the receiving component 4 to open, so that the sheet metal parts slide down, completing the unloading process.

[0032] As the electromagnet 21 lifts the sheet metal part, the workers can place the sheet metal part of the appliance base to be stamped on the top of the lower mold 3, ensuring the working efficiency of the stamping equipment.

[0033] Reference Figure 1 , Figure 2 and Figure 3The hydraulic cylinder 5 is fixedly mounted on the top of the top plate 12. A buffer 51 is fixedly mounted on the output end of the hydraulic cylinder 5. A mounting plate 52 is fixedly mounted on the bottom of the buffer 51. The mounting plate 52 is detachably mounted from the upper mold 2. Two rows of limiting posts 53 are fixedly mounted on the top of the mounting plate 52. The receiving assembly 4 includes a receiving plate A41 and a receiving plate B42. The top of the receiving plate A41 is set as an inclined surface A411 near the receiving plate B42. The top of the receiving plate B42 is set as an inclined surface B421. Two fixed posts 53 are provided at the bottom of both the receiving plate A41 and the receiving plate B42. The connecting rods 43 on both sides are rotatably mounted on the outside of the stamping table 1 via rotating columns 44. A gear 45 is fixedly mounted on one end of each of the two rotating columns 44. The gear 45 rotates under the drive of external force. A limit rod 47 is fixedly mounted on the outside of each of the two connecting rods 43. A lifting rod 46 is fixedly mounted on the top of each of the two rows of limit columns 53. The two lifting rods 46 are both mounted on the outside of the corresponding column 11. Several tooth blocks 461 are fixedly mounted on the bottom of the two lifting rods 46 on the side closest to each other. The tooth blocks 461 on both sides are respectively engaged with the corresponding gears 45.

[0034] The hydraulic cylinder 5 drives the buffer component 51 to rise and fall, which in turn drives the mounting plate 52 to rise and fall, thereby driving the upper mold 2 to rise and fall.

[0035] Hydraulic cylinder 5 drives the buffer component 51 to rise and fall, which in turn drives the mounting plate 52 to rise and fall, thereby driving the two rows of limit posts 53 to rise and fall. The limit posts 53 then drive the lifting rod 46 to rise and fall, which in turn drives several toothed blocks 461 on both sides to rise and fall. These blocks mesh with two gears 45, causing the two gears 45 to drive the two rotating columns 44 to rotate. This, in turn, drives the two connecting rods 43 on both sides to rotate, causing the receiving plates A41 and B42 to open and reset, thus completing the receiving and sliding action of the sheet metal parts for the appliance base. When the receiving plates A41 and B42 are opened to a certain angle, the tooth block 461 disengages from the gear 45. In order to prevent the receiving plates A41 and B42 from rotating downward under the action of gravity, two limiting rods 47 are used to abut against the two sides of the stamping table 1 to limit the receiving plates A41 and B42. In actual use, the receiving plate A41 is longer than the receiving plate B42, and the cooperation of the inclined surface A411 and the inclined surface B421 ensures that the sheet metal parts of the appliance base slide down from one side of the receiving plate A41.

[0036] Reference Figure 1 and Figure 3The top of the mounting plate 52 has a row of balls 521 on both sides. The top of the upper mold 2 is fixedly provided with two L-shaped strips 22 corresponding to the two rows of balls 521. The top of the mounting plate 52 is fixedly provided with two threaded sleeves 522. The inner side of the two threaded sleeves 522 is threaded with bolts B523. The bottom of the two bolts B523 is fixedly provided with protrusions B524. The top of the upper mold 2 has two grooves B23 that match the protrusions B524.

[0037] When installing the upper mold 2, the two L-shaped strips 22 cooperate with the two rows of balls 521 to hang the upper mold 2 on the bottom of the mounting plate 52, so that the groove B23 and the threaded sleeve 522 are basically aligned. The two protrusions B524 contact and cooperate with the two grooves B23 to complete the positioning between the upper mold 2 and the mounting plate 52. The upper mold 2 is installed by threading the two bolts B523 and the two threaded sleeves 522.

[0038] Reference Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The bottom of the lower mold 3 is fixedly provided with two slide bars 31, and the top of the stamping table 1 is fixedly provided with two fixing bars 13 that match the slide bars 31. The bottom of the lower mold 3 is provided with a positioning component 32, and the top of the stamping table 1 is provided with a groove A14 that matches the positioning component 32. The bottom of the lower mold 3 is also fixedly provided with two fixing plates 33. The inner side of the two fixing plates 33 is provided with a common insert plate 34. The inner side of the insert plate 34 is threaded with a bolt A35. The positioning component 32 includes a protrusion A321. The top of the protrusion A321 is fixedly provided with a spring 322. The bottom of the lower mold 3 is provided with a device groove 36, and one end of the spring 322 is fixedly provided with the inner side of the device groove 36.

[0039] When installing the lower mold 3, the two slide bars 31 slide into the two fixed bars 13 from one side. During the sliding process, the protrusion A321 is squeezed by the top of the stamping table 1, which puts the spring 322 in a compressed state until the protrusion A321 slides into the groove A14. Under the elastic action of the spring 322, the protrusion A321 and the groove A14 are engaged, completing the positioning of the lower mold 3 and the stamping table 1. Then, the insert plate 34 is inserted into the inside of the two fixed plates 33. By rotating the bolt A35, the top of the bolt A35 abuts against the bottom of the stamping table 1, completing the installation of the lower mold 3.

[0040] In summary, when the sheet metal stamping device for the appliance base disclosed in this application is in use, the device stamps the sheet metal part of the appliance base by driving the buffer 51 to descend through the hydraulic cylinder 5, which in turn drives the mounting plate 52 to descend, thereby driving the upper mold 2 to descend. At the same time, the hydraulic cylinder 5 drives the buffer 51 to descend, which in turn drives the mounting plate 52 to descend, thereby driving the two rows of limit posts 53 to descend. The two rows of limit posts 53 drive the lifting rod 46 to descend, which in turn drives several toothed blocks 461 on both sides to descend, meshing with two gears 45. The two gears 45 drive the two rotating columns 44 to rotate, thereby driving the two connecting rods 43 on both sides to rotate, causing the receiving plate A41 and receiving plate B42 to open, allowing the upper mold 2 to descend. Mold 2 and lower mold 3 can cooperate to stamp the sheet metal parts of the appliance base. After stamping, the electromagnet 21 is activated to attract the stamped sheet metal parts and lift them up. During the lifting process, the hydraulic cylinder 5 drives the receiving plate A41 and receiving plate B42 to reset, so that the sheet metal parts are raised to a position higher than the receiving component 4. Then, the electromagnet 21 is turned off, so that the electromagnet 21 loses its magnetism, and the sheet metal parts fall to the top of the receiving plate A41 and receiving plate B42. During the next stamping, the hydraulic cylinder 5 drives the upper mold 2 to descend, and the hydraulic cylinder 5 drives the receiving plate A41 and receiving plate B42 to open, so that the sheet metal parts slide down from one side of the receiving plate A41, completing the unloading work.
