Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of punch press, in particular to a high-speed punch press capable of automatic oiling. BACKGROUND

[0002] The high-speed punch press is a kind of punch press equipment for forming blank parts, which forms the parts by high-speed downward impact of the upper die to extrude the blank placed on the lower die. Some cast iron parts adopt hot forming method, which places the heated blank on the lubricated lower die, and then impacts the upper die after lubricating, so that the blank is easily formed. In the hot forming process, the lubrication of the upper die is very important. If the lubrication effect is not good, it will cause defects on the surface of the punched parts, and also easily cause the upper die to wear out quickly.

[0003] The existing lubrication method usually uses a spray head to spray lubrication on the upper die. The sprayed oil or lubricating liquid is recycled to the oil tank through the recovery tank. The filtered oil still has iron filings entering the oil tank. The oil pump sucks the oil through the filter head and then sprays it out through the spray head. After long-term use, it is impossible to detect whether the filter head is blocked. Only the formed parts can be used to judge, which increases the risk of part production. At the same time, when the filter head is blocked, the amount of oil sprayed by the spray head will be reduced and uneven, resulting in insufficient lubrication of the upper die. SUMMARY

[0026] As shown in Figure 1 The upper end of the lifting pipe 23 is fixedly provided with a lifting plate 25, the frame 1 is provided with a lifting cylinder 26 connected with the lifting plate 25, specifically, the cylinder body of the lifting cylinder 26 is fixed on the right end face of the frame 1, and the piston rod end is fixedly connected with the lifting plate 25, initially, the piston rod is in the pushed-out state, when the PLC controller controls the lifting cylinder 26, the piston rod can be lifted upward, so as to lift the filter head 22 at the lower end of the lifting pipe 23 to the upper end face outside of the oil tank 5.

[0027] The upper end wall of the oil tank 5 is provided with a through hole 37 through which the filter head 22 can pass, and an electromagnetic ring 24 is fixedly arranged on the outer wall of the upper end surface of the oil tank 5. When the filter head 22 rises, it can be placed in the inner hole of the electromagnetic ring 24 through the through hole 37. One side of the frame 1 is provided with a second switch 35 and a third switch 36 matched with the lifting plate 25. When the lifting plate 25 is lifted to the top by sliding upward, the second switch 35 and the third switch 36 can be triggered at the same time. The second switch 35 is electrically connected with the electromagnetic ring 24, and when it is triggered, the electromagnetic ring 24 can be powered to have magnetic attraction. After the filter head 22 is lifted to the inner hole of the electromagnetic ring 24 by the lifting plate 25, the electromagnetic ring 24 is activated synchronously and has magnetic attraction. At this time, the iron filings adhered to the surface of the filter head 22 can be adsorbed by the electromagnetic ring 24.

[0028] In order to clean and adsorb the iron filings stuck on the filter head 22, an air pipe is further connected to the upper end of the lifting pipe 23. The air pipe is connected with an air source, and an air valve 34 is arranged on the air pipe. The air valve 34 is connected with the upper end of the lifting pipe 23 through a one-way valve 33. The flow direction of the one-way valve 33 is from the air valve 34 to the lifting pipe 23. The air valve 34 is preferably an electromagnetic air valve. When it is triggered to open, the gas in the air source can be introduced into the lifting pipe 23 to blow the filter head 22, so that the iron filings stuck on the filter head 22 are blown out. The air valve 34 is electrically connected with the third switch 36. When the filter head 22 is placed in the electromagnetic ring 24, the lifting pipe 23 is ventilated, and the iron filings are blown out when the filter head 22 is blown, so that the iron filings are adsorbed on the electromagnetic ring 24.

[0029] The lower mold 4 is provided with a detection assembly matched with the nozzle 6. The detection assembly includes a collection box 7, a collection cover 8, a baffle 9 and a detection cylinder 10. As shown in Figure 2 The piston rod end of the detection cylinder 10 is provided with a liquid level detector 14. The liquid level detector 14 is placed in the collection box 7. Initially, the liquid level detector 14 is in the top position. When the detection cylinder 10 is triggered, the liquid level detector 14 can be slid down to the bottom of the collection box 7. The liquid level detector 14 is a rod-shaped liquid level detector. This is a prior art. The height of the liquid level is detected by the sliding position of the floating ring on the sensor 14 relative to the rod.

[0030] The liquid level detector 14 and the lifting cylinder 26 are connected through a PLC controller. When the liquid level detector 14 does not reach the liquid level height set by the PLC, the lifting cylinder 26 can be triggered to act to clean the filter head 22.

[0031] The spray head 6 is fixed in the collecting cover 8 which is connected with the collecting box 7, and the liquid sprayed by the spray head 6 can be collected in the collecting cover 8. Specifically, the collecting cover 8 is provided with a spray hole 17 matched with the spray head 6. When the spray hole 17 is not blocked, the liquid sprayed by the spray head 6 can lubricate the upper die 3 through the spray hole 17. When the spray hole 17 is blocked by the baffle 9, the liquid sprayed by the spray head 6 will flow back to the collecting box 7 after being sprayed on the baffle 9.

[0032] The baffle 9 is slidingly arranged in the inside of the spray hole 17. Initially, the baffle 9 is in a state of blocking the spray hole 17, as shown in the figure. Figure 2 The upper side wall of the collecting cover 8 is provided with a sliding groove 18 matched with the baffle 9. The baffle 9 is slidingly arranged in the sliding groove 18. One end of the baffle 9 blocks the spray hole 17, and the other end of the baffle 9 is provided with a limiting plate after penetrating the sliding groove 18. The collecting cover 8 is provided with a guide bracket 19 matched with the limiting plate. Specifically, the limiting plate of the baffle 9 is provided with a first spring 11 between the limiting plate and the guide bracket 19. The two ends of the first spring 11 are respectively abutted against the limiting plate and the guide bracket 19.

[0033] The limiting plate of the baffle 9 is fixedly provided with a pull rope 12. The pull rope 12 penetrates the inner hole of the first spring 11 and the guide bracket 19 in sequence and is connected with the movable end of a detection cylinder 10. Specifically, the piston rod end of the detection cylinder 10 is fixedly provided with a detection plate 13. The pull rope 12 is fixed on the detection plate 13. The detection plate 13 extends to the left side and is fixedly connected with a liquid level detector 14 downward. Initially, the piston rod of the detection cylinder 10 is in a state of being pushed out. When the detection cylinder 10 is triggered, the piston rod slides downward, thereby pulling the baffle 9 to slide through the pull rope 12, so that the spray hole 17 is not blocked, and the liquid level detector 14 is placed at the bottom of the collecting box 7.

[0034] The machine frame 1 is provided with a first switch 15 electrically connected with the detection cylinder 10. As shown in the figure, Figure 1 The first switch 15 is arranged on the inside of the left end of the machine frame 1. The sliding block 2 is provided with a contact rod 16 matched with the first switch 15. When the punch press is started, the liquid sprayed by the spray head 6 is collected by the collecting box 7 after being sprayed on the baffle 9. Then, the sliding block 2 is triggered to slide downward by a distance. The contact rod 16 is matched with the first switch 15 to trigger the detection cylinder 10, so that the baffle 9 moves, thereby the spray head 6 sprays the upper die 3 and detects the liquid level of the mobile phone 7. When the liquid level detector 14 detects that the liquid level in the collecting box 7 reaches the PLC preset liquid level height, it indicates that the spray head 6 sprays normally. When the liquid level detector 14 detects that the liquid level in the collecting box 7 is lower than the PLC preset liquid level height, it indicates that the filter head 22 is blocked. At this time, the lifting cylinder 26 is triggered to blow and clean the filter head 22.

[0035] The rack 1 is provided with a warning light 38 outside, which is connected with the liquid level detector 14 through the PLC controller. When the liquid level detector 14 detects that the liquid level in the collecting tank 7 is lower than the preset liquid level of the PLC, the warning light 38 is triggered, at which time the warning light 38 warns the operator to conduct surface detection observation on the punched parts.

[0036] The collecting tank 7 is provided with a drain valve 20 at the bottom, which is connected with the oil tank 5 through a hose. After one-time punching is completed, the PLC controller controls the drain valve 20 to open to add the oil in the collecting tank 7 into the oil tank 5 for recycling.

[0037] The oil tank 5 is provided with a collecting assembly, which comprises symmetrically arranged movable buckets 31 and a collecting cylinder 32. The movable bucket 31 is preferably a semicircular ring-shaped groove. Initially, the two movable buckets 31 are spliced to form a hole in the center through which the lifting pipe 23 passes. The movable bucket 31 is fixedly connected with the piston rod end of the collecting cylinder 32 outside, and the cylinder body of the collecting cylinder 32 is fixedly arranged on the inner side upper wall of the oil tank 5. The collecting cylinder 32 is connected with the liquid level detector 14 through the PLC controller. When the liquid level detector 14 detects that the liquid in the collecting tank 7 does not reach the preset liquid level, the collecting cylinder 32 is triggered to pull the symmetrically arranged movable buckets 31 to both sides, so that the filter head 22 can pass through the gap between the movable buckets 31 when rising. When the filter head 22 is lowered and reset, the PLC controller can trigger the collecting cylinder 32 to reset the movable buckets 31 to the Figure 3 The state, at which time the PLC controller controls the electromagnetic ring 24 to be powered off, so that the iron filings adsorbed on the electromagnetic ring 24 fall into the movable bucket 31 for collection.

[0038] The method for using the high-speed punching machine capable of automatically oiling as described above: the blank is placed on the lower die 4, and the punching machine is started. At this time, the nozzle 6 sprays, the baffle 9 is in the position of shielding the spray hole 17, the liquid sprayed by the nozzle 6 is collected by the collecting cover 8 and then enters the collecting tank 7, and the slider 2 slides a distance to the position where the contact rod 16 contacts the first switch 15. During this period, the liquid collected in the collecting tank 7 reaches a certain liquid level.

[0039] After the contact rod 16 triggers the first switch 15, the detection cylinder 10 lowers and retracts the detection plate 13, so as to place the liquid level detector 14 in the liquid in the collecting tank 7. At the same time, the detection plate 13 pulls the baffle 9 through the pull rope 12 to make the baffle 9 slide relative to the spray hole 17, so as to make the spray hole 17 penetrate and cooperate with the nozzle 6. At this time, the nozzle 6 sprays the upper die 3 through the spray hole 17, and the liquid level detector 14 detects the liquid level in the collecting tank 7.

[0040] When the liquid in the collecting tank 7 is less, i.e. the liquid level detector 14 detects that the liquid level is low and does not reach the set position of the PLC controller, the lifting cylinder 26 and the collecting cylinder 32 are triggered, and the warning light 38 is triggered to light up. The collecting cylinder 32 moves the mobile bucket 31 to slide to both sides, and the lifting cylinder 26 moves the lifting plate 25 to slide upwards so that the filter head 22 is lifted into the electromagnetic ring 24, and the lifting plate 25 triggers the second switch 35 and the third switch 36;

[0041] The second switch 35 triggers the electromagnetic ring 24 to adsorb the iron filings on the surface of the filter head 22, and the third switch 36 triggers the air valve 34 to ventilate, so that the gas is blown from the lifting pipe 25 into the filter head 22 to blow the iron filings stuck in the gap of the filter head 22, and the iron filings are adsorbed by the electromagnetic ring 24;

[0042] When the stamping is completed, the operator sees the warning light 38 light up to check the stamped parts, and the PLC controller controls the lifting cylinder 26 to reset, so that the filter head 22 is reset at the bottom of the oil tank 5, and at the same time, the collecting cylinder 32 is controlled to move the mobile bucket 31 to the initial position. Then, the electromagnetic ring 24 is triggered to be powered off, and the iron filings adhered to the electromagnetic ring 24 fall into the mobile bucket 31 through the perforations 37 after the electromagnetic ring 24 is powered off, so that the iron filings are collected by the mobile bucket 31.

Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalent ones.
