Description

Technical Field

[0002] Metal cans are widely used in our production and life. The advantages of metal cans are very obvious. Its airtightness is very good, and it can withstand relatively high internal pressure, which can ensure that the products in the metal can are not easily expired. During the production and processing of tinplate cans, the two ends of the tinplate can need to be formed by bottom-closing and wire-winding. Since the wire-winding shapes at both ends are inconsistent during the bottom-closing and wire-winding of tinplate cans, different molds are used for pressing the edges at both ends of the tinplate can. This results in the need to go through two processes to complete the bottom-closing and wire-winding operation during the bottom-closing and wire-winding operation of tinplate cans, with low production efficiency; during the pressing process of the existing tinplate can bottom-closing and wire-winding, since the tinplate is held manually, the tinplate often shifts, affecting the lid-making efficiency and quality of the tinplate, with a low yield rate, causing waste of the tinplate, and reducing economic benefits; after the tinplate can is pressed, the worker manually takes out the metal can again. The metal cans can only be produced and processed one by one, with low pressing efficiency. Moreover, since the worker needs to take out the pressed metal cans one by one, the worker is easily injured by the mold of the crank press during the process of taking out the cans, increasing the danger of the worker's production and processing.

[0031] The working principle of this fully automatic tinplate can bottom coiling machine:

[0032] 1. Pneumatic and electric startup: Connect the power supply, and the PLC control device 21, the stamping motor 15, the conveying motor 28, and the air pump work.

[0033] 2. Clamping and translating the tank body: The tank body feeding device conveys the tank body to the clamping and translating device. When the tank body reaches the tank body limit block 31, the tank body laser sensor 30 sends a signal to the PLC control device 21. The PLC control device makes the guide rod of the clamping cylinder 5 extend, so that the first clamp 24 clamps the tank body. The guide rod of the translation cylinder 6 contracts, driving the translation slide rail 52 to translate leftward, and the tank body is translated below the upper die 9;

[0034] 3. Suction the bottom of the tank into the upper die: At the same time, the guide rod of the bottom of the tank lifting cylinder 39 extends, sending the bottom of the tank into the first positioning frame 59 of the bottom of the tank. The suction cup 44 on the upper surface of the bottom of the tank sucks the upper surface of the bottom of the tank. The guide rod of the lifting cylinder 46 of the suction cup on the upper surface of the bottom of the tank contracts, and the transverse cylinder 45 of the suction cup on the upper surface of the bottom of the tank extends, sending the bottom of the tank into the second positioning frame 58 of the bottom of the tank. The guide rod of the transverse cylinder 48 of the suction cup on the lower surface of the bottom of the tank extends, driving the suction cup 41 on the lower surface of the bottom of the tank to the lower part of the second positioning frame 58 of the bottom of the tank. The guide rod of the lifting cylinder 42 of the suction cup on the lower surface of the bottom of the tank contracts, and the suction cup 41 on the lower surface of the bottom of the tank sucks the lower surface of the bottom of the tank. The suction cup 44 on the upper surface of the bottom of the tank disengages. The guide rod of the lifting cylinder 42 of the suction cup on the lower surface of the bottom of the tank extends, and the guide rod of the transverse cylinder 48 of the suction cup on the lower surface of the bottom of the tank contracts, driving the bottom of the tank below the upper die 9. The magnet in the upper die 9 sucks the groove of the bottom of the tank upward to the working surface of the upper die 9;

[0035] 4. Tighten the tank body with the lower die: At the same time, the guide rod of the lifting cylinder 37 of the lower die core fixing plate extends, driving the lower die core fixing plate to move upward along the column 20, so that the lower die core 49 is inserted into the inner cavity of the tank body. The guide rod of the expansion and contraction cylinder 71 of the lower die core contracts, driving the moving expansion and contraction block 65 to move downward through the lever 68 and the expansion and contraction bolt 66. Under the action of the moving expansion and contraction block 65 and the fixed expansion and contraction block 67, the lower die core block 491 expands outward in all directions, and the lower die core 49 tightens the inner cavity of the tank body. The guide rod of the clamping cylinder 5 contracts, and the first clamp 24 disengages from the tank body;

[0036] 5. Return the translation slide rail: At the same time, the guide rod of the translation cylinder 6 extends, driving the translation slide rail 52 to translate leftward and return to its position;

[0037] 6. Support the lower die: At the same time, the guide rod of the support cylinder 34 of the lower die core fixing plate extends, so that the upper end surface of the support block 36 of the lower die core fixing plate supports the lower die core fixing plate 50;

[0038] 7. Clamp the tank body with the outer die of the lower die: Subsequently, the guide rod of the outer die cylinder 2 of the lower die extends, clamping the outer die 4 of the lower die to the tank body;

[0039] 8. Punch and wind the upper and lower openings: Subsequently, the guide rod of the punching cylinder 19 extends, the punching clutch 18 engages, causing the flywheel 17 to rotate. The connecting rod 12 drives the guide rod 11 of the upper die fixing plate to move downward. The guide rod 11 of the upper die fixing plate drives the upper die fixing plate 10 to move downward along the column 20. The impact force makes the bottom of the tank in the upper die 9 snap into the lower opening of the tank body, and at the same time, the operations of winding the lower opening and the upper opening are completed;
