Description

Technical Field

[0001] The invention relates to the technical field of cold rolling forming, and in particular to a metal cold rolling forming device. Background Art

[0002] U-shaped steel is a common steel material with unique shape and characteristics. It is widely used in the fields of construction and civil engineering. During the production and processing of U-shaped steel, the metal plate will be cold-rolled into U-shaped steel through a cold rolling forming device. The cutting mechanism of the cold rolling forming machine is very likely to form a certain amount of metal chips during the cutting process. Some of the metal chips will splash onto the profile or forming roller on the rear side during the cutting process, thereby forming adhesion. If not cleaned in time, it is easy to cause pits in the formed U-shaped steel.

[0003] The Chinese patent document with authorization announcement number CN220879921U discloses a cold rolling guide roller surface cleaning device, which utilizes a circulating felt conveyor belt in cooperation with a cold rolling roller to clean impurities on the cold rolling roller. At the same time, when the impurities on the cold rolling roller are more viscous, the felt conveyor belt will be driven to flip as a whole, thereby increasing the friction between the felt conveyor belt and the cold rolling roller, thereby increasing the effect of the felt conveyor belt on removing impurities on the cold rolling roller, ensuring the cleaning effect of the cold rolling roller, and at the same time utilizing the flexible structure of the felt conveyor belt for wiping to prevent the scraper from directly contacting and damaging the cold rolling roller.

[0004] However, the structural design of the above-mentioned related technology: although it is capable of cleaning the surface of the cold rolling roller, in order to reduce the friction and wear between the metal plate and the cold rolling roller during the cold rolling forming process of the metal plate, it is necessary to spray lubricating oil on the cold rolling roller. At the same time, the lubricating oil can also cool the roller and the strip to reduce heat loss. Although the device removes impurities on the cold rolling roller during the cleaning process, it will also take away a large amount of lubricating oil on the cold rolling roller, resulting in a lack of lubricating oil on the cold rolling roller, thereby affecting the service life of the cold rolling roller and the forming quality of the metal plate.

[0005] Therefore, we propose a metal cold rolling forming device to solve the above-mentioned problems. Summary of the invention

[0006] The invention provides a metal cold rolling forming device, aiming to solve the problem in the related art that a large amount of lubricating oil on the cold rolling roller will be taken away during the process of cleaning the cold rolling roller.

[0011] Beneficial effect: the reciprocating screw drives gear one to rotate through gear three, thereby causing the two brush rollers to rotate. The upper brush roller cleans the lower roller while rotating. During the cleaning process, the reciprocating screw drives the connecting sleeve to move horizontally through the threaded plate. When the connecting sleeve moves to the rotating shaft, the limiting mechanism separates from the base. At this time, the reciprocating screw drives the two brush rollers to revolve around the reciprocating screw through the limiting mechanism, thereby causing the two brush rollers to interchange positions, so that the two brush rollers can be used alternately, relieving fatigue of the bristles on the brush rollers and increasing the service life of the brush rollers. When the two brush rollers have completed the position interchange, the limiting mechanism is inserted into the base again. At this time, the negative pressure pump sucks the lubricating oil on the brush roller after use, and the sucked lubricating oil is sprayed onto the lower roller through the horizontal pipe to avoid waste of lubricating oil.

A fixed tube 36 is installed at the other end of the brush roller 31, and the cavity in the brush roller 31 is connected with the fixed tube 36.

[0049] like Figure 3 and Figure 4 As shown, a rotating ring 37 is rotatably connected to the outer side of the fixed tube 36 on the two brush rollers 31, and a ring groove 29 for the rotating ring 37 to rotate is provided on one side of the support plate 22.

A liquid inlet hole connected to the negative pressure chamber 28 is provided on the ring groove 29 of the support plate 22, and the liquid inlet hole on the support plate 22 is adapted to the fixed tube 36.

[0050] like Figure 2 , Figure 4 and Figure 5 As shown, the driving mechanism includes a reciprocating screw 41, a gear three 42 and a motor 45. The motor 45 is installed on one side of the base 21. The reciprocating screw 41 is rotatably connected to one side of the inner wall of the base 21. The driving shaft of the motor 45 is installed at one end of the reciprocating screw 41, and the gear three 42 is installed at the other end of the reciprocating screw 41. The reciprocating screw 41 is arranged between the two rotating shafts 33, and the gears one 34 on the two rotating shafts 33 are both meshed with the gear three 42.

[0051] The motor 45 can drive the gear three 42 to rotate through the reciprocating screw 41. During the rotation process, the gear three 42 drives the rotating shaft 33 in the gear one 34 to rotate. The rotating shaft 33 drives the brush roller 31 to rotate, so that impurities such as iron filings or dust on the lower roller 13 can be cleaned.

[0052] like Figure 2 , Figure 4 and Figure 5 As shown, the outer thread of the reciprocating screw 41 is connected to a threaded plate 43, and the threaded plate 43 can move back and forth along the length direction of the reciprocating screw 41. Both ends of the threaded plate 43 are equipped with connecting sleeves 44 that are sleeved on the connecting shaft 35. The connecting sleeve 44 can slide on the connecting shaft 35 and can slide to the rotating shaft 33 along the length direction of the connecting shaft 35.

[0053] like Figure 4 and Figure 5 As shown, the limiting mechanism includes a rotating plate 51 and two limiting components 52. A cavity is opened inside the rotating plate 51.

The two limiting components 52 are symmetrically arranged on one side of the rotating plate 51 with the axis of the reciprocating screw 41 as the center, and the connecting shaft 35 is installed on the other side of the rotating plate 51.

[0054] like Figures 5 to 7 As shown, the limit assembly 52 includes a limit plate 521 slidably connected to one side of the rotating plate 51, a connecting plate 522 is installed on the outer side of one end of the limit plate 521, and the other end of the limit plate 521 extends into the cavity of the rotating plate 51, and an elastic member 523 is installed between the rotating plate 51 and the connecting plate 522. In this embodiment, the elastic member 523 is an elastic sheet, and in other embodiments, the elastic member 523 is a spring.

[0055] like Figures 4 to 7 As shown, a hole for inserting a limit plate 521 is opened on one side of the inner wall of the base 21. When the limit plate 521 is inserted on the base 21, it can limit the rotation of the rotating plate 51 on the base 21. When the rotating plate 51 cannot rotate, the connecting shaft 35 cannot revolve around the axis of the reciprocating screw 41, and the motor 45 drives the threaded plate 43 to slide along the length direction of the connecting shaft 35 through the reciprocating screw 41.

[0056] like Figure 5 and Figure 6 As shown, two reset components 55 are installed in the cavity of the rotating plate 51 , a second limit component 53 is installed on one side of the reset component 55 , and one end of the limit plate 521 is slidably disposed in the second limit component 53 .

[0057] like Figure 6 and Figure 7 As shown, the limiting component 2 53 includes a sleeve 531 and two limiting parts, the two limiting parts are respectively installed on both sides of the sleeve 531, the sleeve 531 is installed on one side of the reset component 55, one end of the limiting plate 521 is located inside the sleeve 531, and a rubber sleeve is arranged between the limiting plate 521 and the sleeve 531 to increase the friction between the limiting plate 521 and the sleeve 531.

[0058] Continue to refer Figure 6 and Figure 7As shown, the limiting member includes a mounting box 532 and a limiting rod 536. The mounting box 532 is mounted on one side of the sliding sleeve 531. An elastic member 533 is mounted on one side of the inner wall of the mounting box 532. In the present embodiment, the elastic member 533 is a spring. In other embodiments, the elastic member 533 is an elastic sheet. A slide plate 534 is mounted on one end of the elastic member 533. One end of the limiting rod 536 is mounted on the slide plate 534. The other end of the limiting rod 536 passes through the mounting box 532 and extends to the interior of the sliding sleeve 531. Limiting holes 524 for inserting the limiting rod 536 are provided on both sides of the limiting plate 521.

[0059] like Figure 7 As shown, a slide bar 535 is installed on the top of the slide plate 534, and the top end of the slide bar 535 passes through the installation box 532 and extends to the outside of the installation box 532. The installation box 532 is provided with a groove for the slide bar 535 to slide along the extension direction of the elastic member 533.

[0060] like Figure 6 and Figure 7 As shown, two guide plates 54 are installed on the inner wall of the rotating plate 51, and the guide plate 54 is located on one side of the sliding rod 535. The guide plate 54 has a horizontal portion and a bent portion. The bent portions of the two guide plates 54 are bent in opposite directions. During the sliding movement of the sliding rod 535 on the bent portions of the guide plates 54, the two sliding rods 535 are separated from each other. The sliding rod 535 drives the limiting rod 536 to gradually disengage from the limiting hole 524 through the sliding plate 534. When the sliding rod 535 slides to the end of the guide plate 54, the limiting rod 536 can be completely disengaged from the limiting hole 524.

[0061] like Figures 5 to 7 As shown, the reset assembly 55 includes a movable seat 554, a winding roller 555 and a connecting rope 556. The sliding sleeve 531 is installed on one side of the movable seat 554. The winding roller 555 is rotatably connected to the inner wall of the movable seat 554. The connecting rope 556 is wound on the outer side of the winding roller 555. One end of the connecting rope 556 passes through the rotating plate 51 and is installed on the threaded plate 43. In this embodiment, the connecting rope 556 is a steel wire rope. In other embodiments, the connecting rope 556 is a nylon rope. A coil spring (not shown in the figure) is provided at one end of the winding roller 555 to reel in the connecting rope 556.

[0062] like Figure 6 and Figure 7 As shown, a slider 553 is installed at the bottom of the movable seat 554, and a guide rail 551 is arranged on the outer side of the slider 553. The guide rail 551 is installed on the inner wall of the cavity of the rotating plate 51. The guide rail 551 is slidably connected with the slider 553. An elastic member 3 552 is installed on one side of the slider 553. One end of the elastic member 3 552 is installed on one side of the inner wall of the cavity of the rotating plate 51. In this embodiment, the elastic member 3 552 is a spring. In other embodiments, the elastic member 3 552 is an elastic sheet.

[0063] like Figure 4 As shown, a collecting groove 61 is installed on the inner bottom wall of the base 21, and an adsorbent 62 is installed on the top of the collecting groove 61. The adsorbent 62 is fan-shaped and has a groove for the brush roller 31 to pass through. The adsorbent 62 is made of magnetic material. In the initial state, the brush roller 31 below is located in the groove of the adsorbent 62, so that the adsorbent 62 can remove metal impurities on the brush roller 31 below.

[0064] When in use, the motor 45 drives the gear three 42 to rotate through the reciprocating screw 41, and the gear three 42 drives the two brush rollers 31 to rotate through the two gears 1 34. At this time, the brush roller 31 in contact with the lower roller 13 cleans the lower roller 13, thereby removing dust or iron filings on the lower roller 13. The reciprocating screw 41 can also drive the threaded plate 43 to move during the rotation process, so that the connecting sleeve 44 on the threaded plate 43 is close to the rotating shaft 33. During the movement of the threaded plate 43, the threaded plate 43 drives one end of the connecting rope 556 to move. The threaded plate 43 moves to move the winding roller 555 to release the connecting rope 556. When the connecting rope 556 is released to the limit, the connecting sleeve 44 moves to the end of the connecting shaft 35. As the threaded plate 43 continues to move, the threaded plate 43 drives the movable seat 554 to move through the connecting rope 556. The elastic member three 552 is gradually stretched. At this time, the movable seat 554 drives the limiting rod 536 to move through the sliding sleeve 531. The limiting rod 536 drives the limiting plate 521 to gradually separate from the base 21. The elastic member 1 523 is gradually compressed. At the same time, the sliding rod 535 moves along the trajectory of the guide plate 54.

[0065] When the connecting sleeve 44 moves to the outside of the rotating shaft 33, the limiting plate 521 is completely separated from the base 21, and the sliding rod 535 moves to the end of the guide plate 54, so that the limiting rod 536 moves out of the limiting hole 524 of the limiting plate 521. At this time, the reciprocating screw 41 first drives the connecting shaft 35 in the connecting sleeve 44 to rotate around the axis of the reciprocating screw 41 through the threaded plate 43, thereby driving the rotating plate 51 to rotate. During the rotation of the rotating plate 51, the rotating shaft 33 drives the two brush rollers 31 to interchange positions, thereby By replacing the new brush roller 31, the two brush rollers 31 are used alternately, thereby alleviating the fatigue of the bristles on the brush roller 31 and increasing the service life of the brush roller 31. At the same time, the fixed tube 36 on the used brush roller 31 corresponds to the liquid inlet hole on the annular groove 29. During the rotation of the rotating plate 51, the end of the limit plate 521 is against the base 21, but because it is not directly opposite to the hole on the base 21, the limit plate 521 is not inserted into the hole of the base 21, and the limit plate 521 does not restrict the rotation of the rotating plate 51.

[0066] When the positions of the two brush rollers 31 are interchanged, the elastic member 523 is reset and drives the limit plate 521 to be inserted into the hole of the base 21 again. At this time, the limit rod 536 is misaligned with the limit hole 524 of the limit plate 521, and the reciprocating screw 41 drives the connecting sleeve 44 away from the rotating shaft 33 through the threaded plate 43, so that the threaded plate 43 is gradually reset. At the same time, the reciprocating screw 41 drives the two gears 34 to rotate through the gear three 42, so as to drive the two brush rollers 31 that have interchanged their positions to rotate.

[0067] During the rotation of the two brush rollers 31, the adsorption member 62 first adsorbs the metal impurities on the used brush roller 31, and then the negative pressure pump 23 is started. At this time, negative pressure is generated in the used brush roller 31, and the dust and lubricating oil on the bristles of the brush roller 31 are sucked into the cavity of the brush roller 31 through the negative pressure. After the lubricating oil enters the cavity, it enters the negative pressure chamber 28 through the fixed pipe 36. At this time, the lubricating oil in the negative pressure chamber 28 is filtered by the oil filter 27 and then transported to the cross pipe 25 by the connecting pipe 24. The lubricating oil in the cross pipe 25 is sprayed onto the lower roller 13 through the oil spray pipe 26, so that the scraped lubricating oil is sprayed onto the lower roller 13 again, thereby avoiding the waste of lubricating oil.

[0068] When the threaded plate 43 is resetting, the winding roller 555 winds up the connecting rope 556 , and at the same time the elastic member 552 drives the movable seat 554 to reset. When the movable seat 554 is reset, the limiting rod 536 on the movable seat 554 is inserted into the limiting hole 524 on the limiting plate 521 again.

[0069] As the usage time increases, the metal impurities adsorbed on the adsorbent 62 will gradually increase. When the two brush rollers 31 are switched again, the brush rollers 31 are likely to take away the metal impurities on the adsorbent 62. To overcome the above disadvantages, the present invention provides a second embodiment.

[0070] like Figure 8 and Fig. 9 The second embodiment of the present invention is shown in FIG. 1 . The difference between the second embodiment and the first embodiment lies in that a scraper 63 is slidably connected to the inner wall of the adsorption member 62, and the scraper 63 can rotate around the axis of the reciprocating screw 41, and connecting rods 64 are installed on both sides of the scraper 63. The adsorption member 62 is provided with an arc groove for the connecting rod 64 to slide, and one end of the connecting rod 64 passes through the adsorption member 62 and extends to the outside of the adsorption member 62. A fixing sleeve 65 is installed on the outside of one end of the connecting rod 64, and an elastic member four 66 is installed on one side of the fixing sleeve 65. In this embodiment, the elastic member four 66 is a spring, and in other embodiments, the elastic member four 66 is an elastic sheet or an elastic rope. A mounting plate 67 is installed on one end of the elastic member four 66, and the mounting plate 67 is installed on one side of the adsorption member 62.

[0071] like Figure 8As shown, push plates 46 are installed on the two connecting sleeves 44, and the push plates 46 can push the connecting rod 64 to move.

[0072] During the process of the two brush rollers 31 being interchanged in position, the upper push plate 46 pushes the connecting rod 64 to move, causing the scraper 63 to move in the adsorption member 62, and at the same time, the elastic member 66 is stretched, thereby scraping the metal impurities adsorbed in the adsorption member 62 out of the adsorption member 62. When the two brush rollers 31 are interchanged in position, the reciprocating screw 41 drives the push plate 46 to gradually disengage from the connecting rod 64 through the connecting sleeve 44 on the threaded plate 43. At this time, the scraper 63 is reset by resetting the elastic member 66.

[0073] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
