Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and in particular to a stamping coil cleaning device. Background Technology

[0002] Stamping generally refers to stamping products into the required shape from sheet metal. Before stamping, sheet metal is mostly in rolls, also called stamping coils. Stamping coils are generally exposed during transportation, storage, and feeding into stamping equipment, making them prone to accumulating dirt and granular impurities. For dirt, a cleaning step is usually performed after stamping. For granular impurities, air is often blown onto the sheet metal using nozzles. However, the cleaning effect of air blowing is generally limited. Residual dirt and granular impurities adhere to the surface of the sheet metal, which can damage the product surface when the sheet metal is stamped in the mold, resulting in a decrease in product surface quality. Utility Model Content

To this end, this invention proposes a stamping coil cleaning device, which can clean dirt and particulate impurities from the sheet metal before it enters the stamping equipment, achieving a good cleaning effect.

[0004] A stamping coil cleaning device according to an embodiment of the present invention includes a tank and a pair of cleaning wiping cloths. The tank is used to hold cleaning liquid. The cleaning wiping cloths are elastic. The pair of cleaning wiping cloths are distributed vertically. The length direction of the pair of cleaning wiping cloths is both horizontal. A cleaning cloth is provided on the outer circular surface of the cleaning wiping cloths. The gap between the pair of cleaning wiping cloths allows the sheet material to pass through from front to back. The gap between the pair of cleaning wiping cloths is lower than the liquid level of the cleaning liquid, so that the cleaning cloth absorbs the cleaning liquid and wipes the upper and lower surfaces of the sheet material.

[0005] It has at least the following beneficial effects:

[0006] One end of the sheet metal is passed through the gap between a pair of cleaning wipers from front to back, so that two layers of cleaning cloth, distributed vertically, rest against the upper and lower surfaces of the sheet metal. Cleaning liquid is injected into the tank, submerging the gap between the cleaning wipers, causing the cleaning cloths to absorb the liquid. When the stamping equipment or other processing equipment is operating, the sheet metal moves from front to back to be conveyed to the equipment. As the sheet metal moves backward relative to the cleaning wipers and cleaning cloths, relative movement occurs between the cleaning cloths and the sheet metal, allowing the cleaning cloths to wipe away dirt and particulate impurities from the upper and lower surfaces of the sheet metal. The cleaning effect is good. This cleaning device can clean dirt and particulate impurities from the sheet metal before it enters the stamping equipment, ensuring the surface quality of the stamped product.

[0036] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0037] Reference Figures 1 to 4This utility model discloses a stamping coil cleaning device, including a tank 100, a liquid suction device and a pair of cleaning wipes 200.

[0038] The tank 100 is used to hold cleaning fluid, which can be water or cutting fluid, etc.

[0039] The cleaning wipe 200 is elastic. When the cleaning wipe 200 is squeezed, the surface of the cleaning wipe 200 can undergo elastic deformation. A pair of cleaning wipes 200 are distributed vertically, and the length direction of the pair of cleaning wipes 200 is both horizontal. A cleaning cloth 300 is provided on the outer circular surface of the cleaning wipe 200. The gap between the pair of cleaning wipes 200 allows the board to pass through from front to back. The gap between the pair of cleaning wipes 200 is lower than the liquid level of the cleaning liquid, so that the cleaning cloth 300 can absorb the cleaning liquid and wipe the upper and lower surfaces of the board.

[0040] One end of the sheet metal is passed through the gap between a pair of cleaning wipers 200 from front to back, so that two layers of cleaning cloths 300, distributed vertically, press against the upper and lower surfaces of the sheet metal. Cleaning liquid is injected into the tank 100, submerging the gap between the cleaning wipers 200, causing the cleaning cloths 300 to absorb the liquid. When the stamping equipment or other processing equipment is operating, the sheet metal moves from front to back to be conveyed to the equipment. As the sheet metal moves backward relative to the cleaning wipers 200 and cleaning cloths 300, relative movement occurs between the cleaning cloths 300 and the sheet metal, allowing the cleaning cloths 300 to wipe away dirt and particulate impurities from the upper and lower surfaces of the sheet metal. The cleaning effect is good. This cleaning device can clean dirt and particulate impurities from the sheet metal before it enters the stamping equipment, ensuring the surface quality of the stamped product.

[0041] Reference Figures 3 to 5 In some embodiments, the cleaning device further includes a liquid suction device comprising an upper adhesive cotton component 400 and a lower adhesive cotton component 500 distributed vertically. The length direction of the upper adhesive cotton component 400 and the lower adhesive cotton component 500 is both horizontal. The upper adhesive cotton component 400 and the lower adhesive cotton component 500 are positioned above and behind a pair of cleaning wipes 200. The upper adhesive cotton component 400 and the lower adhesive cotton component 500 are above the liquid level of the cleaning liquid. The area between the upper adhesive cotton component 400 and the lower adhesive cotton component 500 is for the sheet metal to pass through. The upper adhesive cotton component 400 and the lower adhesive cotton component 500 are used to absorb the liquid on the sheet metal, so that the sheet metal is dried as soon as possible, so that the sheet metal processed by the stamping equipment is in a dry state.

[0042] Reference Figure 1 , Figure 3 and Figure 5In some embodiments, the cleaning device further includes a support 600, which is movably disposed within the tank 100. The cleaning wiping 200 is connected to the support 600. The cleaning wiping 200 can be placed within the tank 100 via the support 600, and the cleaning wiping 200 can also be moved via the support 600. When a pair of cleaning wiping 200s are above the cleaning liquid, the plate can be passed from front to back through the gap between the pair of cleaning wiping 200s without getting your hands wet.

[0043] Reference Figure 2 In some embodiments, the cleaning wipe 200 includes a roller 210 and an elastic ring 220 movably sleeved on the roller 210. A cleaning cloth 300 is wound around the elastic ring 220. One end of the roller 210 is connected to a support 600 and has a shoulder. The other end of the roller 210 is a screw section with a fastener 230 threaded onto it. When the fastener 230 is tightened, it presses the elastic ring 220 against the shoulder, thereby fixing the elastic ring 220 and the cleaning cloth 300 onto the roller 210, and then fixing the elastic ring 220 and the cleaning cloth 300 onto the support 600. The fixed area on the cleaning cloth 300 contacts the board, thereby wiping the upper / lower surface of the board.

[0044] Loosening fastener 230 causes the elastic ring 220 and cleaning cloth 300 to rotate. As the area of ​​the cleaning cloth 300 wiping the board increases and the wiping time increases, the dirt and particulate impurities on the area of ​​the cleaning cloth 300 in contact with the board increase, and the cleaning cloth 300 also wears down. By rotating the elastic ring 220 and cleaning cloth 300, the area of ​​the cleaning cloth 300 in contact with the board can move forward, allowing other clean areas of the cleaning cloth 300 to come into contact with the board. This allows the other clean areas of the cleaning cloth 300 to wipe the upper / lower surfaces of the board, making full use of all areas of the cleaning cloth 300 while ensuring the cleaning effect of the board. It is conceivable that fastener 230 could be a wing nut.

[0045] Reference Figure 1 , Figure 3 and Figure 5 In some embodiments, the cleaning device further includes a lifting arm 700, which is V-shaped. A support plate 110 is connected to the tank 100. One end of the lifting arm 700 is hinged to the support plate 110. The middle section of the lifting arm 700 is connected to a support 600. The other end of the lifting arm 700 is for hand gripping. When the other end of the lifting arm 700 is swung upward by hand or other tools, the support 600 swings upward with the lifting arm 700, thereby driving the support 600 to swing upward. The support 600 carries a pair of cleaning wiping pads 200 upward to the top of the cleaning liquid. The plate can be passed through the gap between the pair of cleaning wiping pads 200 without having to put hands or other tools into the cleaning liquid.

[0046] The middle section of the lifting arm 700 is connected to the support 600 by a hinge, which ensures that the support 600 remains vertical when swinging upwards and downwards, which in turn ensures that the pair of cleaning wipes 200 maintain an up-down distribution when rising and falling.

[0047] As the boards are continuously conveyed, the cleaning liquid absorbed by the upper adhesive cotton part 400 and the lower adhesive cotton part 500 increases. In order to ensure the effectiveness of the upper adhesive cotton part 400 and the lower adhesive cotton part 500 in absorbing the cleaning liquid, that is, to ensure the effectiveness of wiping the cleaning liquid off the boards, it is necessary to squeeze out the cleaning liquid absorbed by the upper adhesive cotton part 400 and the lower adhesive cotton part 500 in a timely manner.

[0048] Reference Figure 1 In some embodiments, the cleaning device further includes a support 800 and a drive device 900 disposed on the support 800. The support 800 is provided with an upper squeezing group and a lower squeezing group. The drive device 900 is used to drive the upper squeezing group and the upper rubber cotton piece 400 to squeeze each other to squeeze out the cleaning liquid absorbed by the upper rubber cotton piece 400. The drive device 900 is also used to drive the lower squeezing group and the lower rubber cotton piece 500 to squeeze each other to squeeze out the cleaning liquid absorbed by the lower rubber cotton piece 500.

[0049] The bracket 800 is located inside the tank 100. The bracket 800 serves to support the drive device 900, the upper extrusion group and the lower extrusion group inside and above the tank 100.

[0050] Reference Figure 4 and Figure 5 In some embodiments, the upper squeezing assembly includes two upper squeezing rollers 810, both of which are lateral in length. The two upper squeezing rollers 810 are positioned at the front and rear of the upper adhesive cotton component 400, and both are located above the upper adhesive cotton component 400. The output end of the driving device 900 is connected to the upper adhesive cotton component 400. The driving device 900 is used to drive the upper adhesive cotton component 400 to rise, so that the front and rear sides of the upper adhesive cotton component 400 are squeezed by the two upper squeezing rollers 810 respectively. That is, during the rising process of the upper adhesive cotton component 400, the two upper squeezing rollers 810 squeeze the front and rear sides of the upper adhesive cotton component 400, thereby squeezing out the cleaning liquid adsorbed by the upper adhesive cotton component 400.

[0051] Reference Figure 4 and Figure 5In some embodiments, the drive device 900 includes a handle 910 and a pull rod 920. One end of the handle 910 is hinged to the bracket 800, and the other end of the handle 910 faces downward and is close to the upper adhesive piece 400. The other end of the handle 910 is for hand gripping. The middle section of the handle 910 is hinged to one end of the pull rod 920, and the other end of the pull rod 920 is hinged to the upper adhesive piece 400. When the other end of the handle 910 is driven to swing upward, the handle 910 pulls the upper adhesive piece 400 upward through the pull rod 920.

[0052] In some embodiments, the lower squeezing assembly includes two lower squeezing rollers 820, both extending horizontally. The two rollers 820 are positioned at the front and rear of the lower adhesive cotton component 500, respectively, and are both below the component. The output end of a drive device 900 is connected to the lower adhesive cotton component 500, which drives the component to descend, causing the front and rear sides of the component to be squeezed by the two lower squeezing rollers 820. In other words, during the descent of the component, the two lower squeezing rollers 820 squeeze the front and rear sides of the component, effectively removing the cleaning liquid absorbed by the component.

[0053] Reference Figure 4 and Figure 5 In some embodiments, the drive device 900 further includes a cable 930, a first pulley 940, and a second pulley 950. The first pulley 940 and the second pulley 950 are both mounted on the bracket 800. The first pulley 940 is located below the lower rubber cotton component 500, and the second pulley 950 is located above or behind the first pulley 940. One end of the cable 930 is connected to the middle section of the handle 910. The cable 930 is wound around the first pulley 940 and the second pulley 950 in sequence. The other end of the cable 930 is connected to the lower rubber cotton component 500.

[0054] When the other end of the handle 910 is swung upwards, the handle 910 pulls down the lower rubber cotton component 500 through the cable 930, causing the lower rubber cotton component 500 to descend, thereby achieving the simultaneous rise of the upper rubber cotton component 400 and the descent of the lower rubber cotton component 500.

[0055] In some embodiments, the cleaning device further includes an elastic element 960, which drives the upper adhesive pad 400 and the lower adhesive pad 500 closer together, thereby maintaining the clamping effect of the upper adhesive pad 400 and the lower adhesive pad 500 and ensuring that the upper adhesive pad 400 and the lower adhesive pad 500 can fully absorb the cleaning liquid on the board. The elastic element 960 may be a tension spring, with its two ends connected to the upper adhesive pad 400 and the lower adhesive pad 500, respectively.

[0056] Understandably, the support 800 includes two vertical plates distributed to the left and right, both of which are perpendicular to each other in the left-right direction. The two ends of the upper squeezing roller 810 are respectively mounted on the two vertical plates, and the two ends of the lower squeezing roller 820 are respectively mounted on the two vertical plates.

[0057] Reference Figure 4 and Figure 5 There are two of each of the following components: handle 910, lever 920, cable 930, first pulley 940, and second pulley 950. One handle 910, one lever 920, one cable 930, one first pulley 940, and one second pulley 950 form a drive unit. The two drive units are located on two vertical plates. The other ends of the two levers 920 are connected to the two ends of the upper rubber cotton component 400, and the other ends of the two cables 930 are connected to the two ends of the lower rubber cotton component 500. The other ends of the two handles 910 are connected to each other by a grip.

[0058] In some embodiments, the tank 100 is equipped with a magnetic element for adsorbing metal impurities that fall from the board. When the cleaning cloth 300 wipes the board, the metal particulate impurities and metal burrs that fall from the board are adsorbed by the magnetic element, preventing the metal particulate impurities and metal burrs from re-adhering to the board and ensuring the cleaning effect of the board.

[0059] The magnetic component can be a magnet. The bottom of the tank 100 is provided with multiple support feet. A drain pipe is provided at the bottom of the tank 100.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
