Description

  The present invention relates to a machine part cleaning apparatus for cleaning various machine parts that are cold forged by a parts homer.

  Large parts (diameter 20 mm, weight 100 g to diameter 40 mm, weight 300 g) and small parts (diameter 10 mm, weight 100 g or less) that are forged by a parts homer (cold forging machine) are usually one speed per second. In order to cool forging heat and lubricate molds and forgings, it is generally produced by continuous forging while applying cooling oil (oil) mixed with additives such as chlorine and sulfur to the base of turbine oil. . The cooling oil (oil) is made of high clay so as to be effective for lubrication between the pressed product and the mold.

  As a result of the forging process as described above, in particular, a large amount of oil (cooling oil) O is present on the surface of a large part or the inner bottom of the cup-shaped part P as shown in FIGS. 8 (a) and 8 (b). Adhering a lot in an uncontrolled state. Particularly in the case of a complicatedly shaped part such as a cup-shaped part P, the oil O is non-uniform and adheres more than necessary, causing an inconvenient problem. However, for quality control, it is necessary that the oil film of oil O is thinly and uniformly attached to the entire surface of the component P, in order to prevent the occurrence of rust.

  Due to the high temperature (around 300 ° C) due to the generation of forging heat during or after forging production, even in liquefied oil, the oil that has been stored in stock for a while after processing solidifies and becomes a paste. . Moreover, when time passes, it will change color and the value as a goods of components will fall. In the next process, when the finished product is subjected to secondary processing such as cutting and plating, the solidified paste causes many problems in accuracy and automation. However, the fact that the oil film is thin and an appropriate amount of oil uniformly adheres to the surface does not generate rust, and is considered good in production management.

  In order to eliminate these inconveniences, removal of the component surface-adhered oil immediately after forging by some method is performed. Many of the devices are connected inline by a forging machine and chutes and conveyors.

  In general, there are the following methods for removing oil adhering to the component surface. One of them is that the oil removal process for several minutes is completed in an unmanned state automatically with a timer or the like by a centrifuge having a high-speed rotating drum in a state where hundreds to thousands of parts are put in a bucket. However, the following problems occur.

(1). The parts are in close contact with each other in a folded state, and the surface cannot be completely deoiled in some places, resulting in unevenness of the oil film.
(2). Oil accumulated at the bottom of complicated shaped parts, particularly cup-shaped parts, rotates with the parts being tightly fixed, and therefore cannot be deoiled 100% depending on the position and direction.

In addition, the method of spraying cleaning oil (light oil) or hot water in the shower while the parts are moving on the in-line conveyor parts, and transferring them to the product can as they are, has the following problems There is a point.
(1). The oil collected on the bottom of complicated shaped parts and especially cup-shaped parts is fixed in the direction of the parts. it can. FIGS. 9A and 9B show a state where oil removal is insufficient and oil remains attached to the recesses and corners of the cup-shaped part P. FIG.
(2). Since cleaning oil (light oil) is volatile and has a low flash point, hot parts after forging are ignited by mist-like oil, which is very dangerous.
(3). With cleaning oil (light oil) and hot water, there is a risk that the product will rust later.

  The present invention can solve the above-mentioned problems, and can effectively remove excess oil adhering to the machine parts after forging, and the surface of the parts after washing is washed with a rust inhibitor and washed. It is an object of the present invention to provide a machine parts cleaning device that can prevent the oil from being uniformly and thinly attached and prevent the cleaned parts from being rusted.

  Means for solving the above problems will be described with reference numerals of the embodiments described later. The invention according to claim 1 is a mechanical part cleaning apparatus for cleaning various mechanical parts P forged by the parts homer 7.

  Claim 2 is the machine part cleaning apparatus according to claim 1, wherein the opposite ends in the rectangular tube body 25 whose upper and lower ends are opened below the water surface WL in the pool 1 located above the starting end side of the conveyor 2 for conveying and cleaning. The buffer shelf 5 is formed by alternately projecting downwardly inclined shelf plates 26 having soft plate surfaces from both side surfaces 25a, 25a in a plurality of upper and lower stages, and the rectangular cylinder 25 is cleaned from above. The parts P are put in and supplied onto the start end of the conveyor 2 while being sequentially dropped from the upper shelf 26 to the lower shelf 26.

  According to a third aspect of the present invention, in the machine part cleaning apparatus according to the first or second aspect, the vibrator 15 is attached to the conveyor 2 for conveying and cleaning, and the conveyor 2 is vibrated.

  According to a fourth aspect of the present invention, in the machine part cleaning apparatus according to any one of the first to third aspects, clean water containing oil sucked from the pool 1 by the float-type oil skimmer 4 is introduced into the oil / water separation tank 20 and separated. Only fresh water in the tank 20 is returned to the pool 1.

  According to a fifth aspect of the present invention, in the machine part cleaning apparatus according to any one of the first to fourth aspects, the part to be cleaned P carried out from the terminal end side of the conveyor 2 for transporting and cleaning is received at the start end side, and a vibration is generated in this.

According to the mechanical component cleaning apparatus of the first aspect of the present invention, the deoiled cleaning of the component P to be cleaned is performed in the pool 1. Since the parts to be cleaned P can be moved and discharged individually, the occurrence of dents due to interference between the parts to be cleaned P can be prevented. Further, since the parts to be cleaned P are deoiled and cleaned while the parts to be cleaned P are moved by the transport cleaning conveyor 2 in the warm water in the pool 1, the bottoms of the parts to be cleaned P, particularly the cup-shaped parts, are removed. Even oil accumulated in the oil is easily deoiled and can be prevented from solidifying into a paste. And in the to-be-cleaned part P conveyed from the conveyor 2 for conveyance washing and rising from the water surface WL, the washing water CW which consists of clean warm water which avoided the dirty floating oil in the washing water CW in the pool 1 is Since it is ejected by the shower 3, final dirt, fine iron powder and the like can be surely removed.

Therefore, the deoiled oil and the semi-oil state oil can be efficiently sucked and discharged.

  In addition, the cleaning water CW in the pool 1 is mixed with a rust preventive agent and contains an appropriate amount of oil that has been cleaned and deoiled in the pool 1 so that the entire surface of the cleaned parts is thin. Since it adheres uniformly, it can prevent the occurrence of rust after being washed and discharged, and does not impair the product value of machine parts. Further, since the parts to be cleaned P are warmed by the hot water as the cleaning water CW while passing through the pool 1, a very small amount of adhering water that causes rust is evaporated and removed by the residual heat of the parts that have been cleaned.

  In the case where the buffer shelf 5 is provided as in the invention according to claim 2, the parts P to be cleaned put into the rectangular tube body 25 of the buffer shelf 5 are moved from the upper shelf 26 into the wash water CW. While falling to the side shelf 26 sequentially, the oil (cooling oil) O adhering by vibration when hitting each shelf 26 is deoiled or easily deoiled. In this case, since the surface of each shelf plate 26 is soft, the impact when the component P to be cleaned hits the shelf plate 26 is mitigated, the surface of the component P to be cleaned is not damaged, and the falling speed is reduced. Since it becomes loose, it will not be damaged when it falls on the conveyor 2 for transport and washing.

  In the case where the vibrator 15 is attached to the conveyor 2 for conveying and cleaning and the conveyor 2 is vibrated as in the invention according to claim 3, deoiling cleaning with the cleaning water CW in the pool 1 and Deoiling and cleaning by spraying the cleaning water CW in the shower 3 can be performed more effectively.

  The operation of the machine part cleaning apparatus configured as described above will be described. First, the part P to be cleaned, which is forged by the parts homer 7, is placed on the start side horizontal conveyance unit 6 a of the part supply conveyor 6 to be cleaned by the conveyor 8. From here, it passes through the upward inclined conveying section 6a and is fed into the rectangular cylinder 25 of the buffer shelf 5 in the pool 1 from the end side horizontal conveying section 6c. The parts P to be cleaned by the parts homer 7 are cup-shaped parts with a large amount of oil (cooling oil) O attached to the inner bottom as shown in FIGS. 8 (a) and 8 (b). It shall be.

  The parts P to be cleaned put into the rectangular cylinder 25 of the buffer shelf 5 sequentially drop from the upper shelf 26 to the lower shelf 26 in the cleaning water CW made of warm water containing a rust inhibitor. In the meantime, the oil (cooling oil) O adhering by vibrations when hitting each shelf 26 is deoiled or easily deoiled. In this case, since the surface of each shelf plate 26 is soft, the impact when the component P to be cleaned hits the shelf plate 26 is mitigated, the surface of the component P to be cleaned is not damaged, and the falling speed is reduced. Since it becomes loose, it will not be damaged when it falls on the conveyor 2 for transport and washing. By passing through the buffer shelf 5 in this manner, the parts P to be cleaned are slowly and slowly dropped and supplied onto the start-end-side horizontal transfer unit 2a of the conveyor 2 for transfer cleaning while being deoiled and cleaned.

  The parts to be cleaned P supplied onto the start-end-side horizontal transfer unit 2a of the transfer cleaning conveyor 2 transfer the cleaning water CW made of warm water containing a rust preventive agent from the horizontal transfer unit 2a to the upward inclined transfer unit 2a.

  On the other hand, on the water surface WL in the pool 1, dirty deoiled oil that is lighter than water and semi-oiled oil (hot water containing a large amount of oil components) float in a mixed state. The deoiled oil and the semi-oiled oil are sucked and removed by the oil skimmer 4. In this case, the oil skimmer 4 is placed at a position where the central portion of the pool 1 can be easily recovered, and is a float type oil skimmer that can move over almost the entire area of the pool 1 while floating on the water surface WL. Therefore, the deoiled oil and the semi-oil state oil can be efficiently and effectively sucked and discharged. And the deoiled oil which is the clean water containing the oil sucked from the pool 1 by the oil skimmer 4 and the oil in the semi-oil state are separated into oil and fresh water by being introduced into the oil / water separation tank 20, Since only clean fresh water is returned to the pool 1 and recycled, water can be used effectively and it is economical.

  The temperature of the hot water in the pool 1, the concentration of the rust inhibitor and the amount of water are automatically controlled to predetermined values. If the amount of water in the pool 1 decreases, it is replenished one after another, and if the concentration of the rust inhibitor is reduced, it is appropriately prevented. The rusting agent is replenished, and the water temperature is also maintained at a predetermined temperature between 60 ° C. and 80 ° C. by the pipe heater 11.

  Depending on the material of the machine parts that are forged by the parts homer 7, when using cooling oil with high viscosity, the parts to be cleaned conveyed by the conveyor 2 by starting the vibration generator 15 to vibrate the conveyor 2 By applying vibration to P, it is possible to more effectively perform the deoiling cleaning by the cleaning water CW in the pool 1 and the deoiling cleaning by jetting the cleaning water CW in the shower 3.

  FIG. 7 shows the cleaned part Po that has been cleaned as described above. That is, the cleaning water CW contains a rust preventive agent and contains an appropriate amount of oil O that has been cleaned and deoiled in the pool 1, and adheres thinly and uniformly to the entire surface of the component to be cleaned. Therefore, it is possible to prevent the occurrence of rust after being washed and discharged, and the product value of the machine parts is not impaired. Further, while the parts to be cleaned P pass through the pool 1, they are warmed by the hot water that is the cleaning water CW, so that a small amount of adhering water that causes rust is evaporated and removed by the residual heat of the parts that have been cleaned.

  FIG. 5 is a longitudinal side view showing a vibration shooter 36 provided between the end of the conveyor 2 for conveying and cleaning and the product can 27, and FIG. 6 is a plan view thereof. The vibration shooter 36 receives the part P to be cleaned carried out from the terminal end side of the conveyor 2 for conveying and cleaning at the start end side, and gives vibration to the component P by a vibration generator 37, while the end side located at a position lower than the start end side. It is made to slide and discharge on the down-sloped cage-like chute 38, and as shown in FIGS. 5 (a) and 5 (b), on the base 39, there are four front and rear, right and left buffers. A chute mounting base 41 is installed via a spring 40, and a downhill scissor-shaped chute 38 is attached to the chute base 41 and a vibrator 37 is installed via a vibrator support frame 42 to form a scissor-shaped base.
