Description

[Detailed description of the invention] The present invention relates to a punch lubricant application device.

Conventionally, for example, when applying lubricant to the outer peripheral surface of a forging punch, it has been applied by hand using a brush or the like, or by spraying the lubricant. For this reason, the hand-applying method requires manpower, and it is labor-intensive and inefficient to apply it evenly, and even the spray-only method requires manpower, and more lubricant is sprayed than necessary, leading to waste and fire hazards. There were many inconveniences, including the risk of outbreaks.

According to the present invention, many of these conventional inconveniences are eliminated, and it is possible to provide a punch lubricant application device that can be unmanned, efficiently applies lubricant to the necessary minimum amount, and is safe. It is something.

An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 to 3, A is a lubricant storage tank, B is a lubricant supply pump, C is a lubricant injection nozzle, D is a lubricant application member, and E is a conveyance device for the lubricant application member. P is a punch to which lubricant is applied.

The lubricant stored in lubricant storage tank A is pipe 1.
The lubricant is supplied to the lubricant supply pump B through the lubricant supply pump B. As shown in FIG. 4, in the lubricant supply pump B, a piston 5 is slidable inside a cylinder body 4 whose both ends are fixed to cylinder covers 2 and 3. Air chamber 6 divided by piston 5
A, 6b are provided with air inlet/output lowers a, 7b. The piston rod 8 protrudes through one cylinder cover 2, and a lubricant storage chamber 9 is provided between the piston rod 8 and the cylinder cover 2, which becomes a narrower diameter portion 8a from the middle, and this chamber is used to suck lubricant. A port 10a and a discharge port 10b are provided.

The tip of the narrow diameter portion 8a is a threaded portion 8b. A cylindrical body 11 is fitted into the threaded portion 8b, and a nut 12 for adjusting the stroke of the piston is screwed onto the tip of the threaded portion protruding from the cylindrical body. By changing the screwing position of the nut 12, it is possible to adjust the stroke as well as the amount of lubricant to be discharged.

The lubricant in the lubricant storage chamber 9 is supplied to the lubricant injection nozzle C through the pipe 13. As shown in FIG. 5, a nozzle body 15 is fixed to the tip of the cylindrical body 14 of the lubricant injection nozzle C, which has a center hole 15a and a female thread 15b, and has a dish-shaped recess 15c on the upper surface. . The nozzle lid also has a center hole 16a, a male screw 16b screwed into the female screw 15b, and a plurality of radial communication holes 16c communicating from the center hole 16a to the recess 15c. The body 16 is screwed and fixed to the nozzle body. A narrow gap 17 is provided on the outer periphery of the opposing surfaces of the nozzle body 15 and the nozzle lid 16, and communicates with the recess 15c. Note that instead of a gap, a thin triangular radial groove may be provided on the opposing surface. Such a lubricant injection nozzle C is fixedly supported on the frame 17. The frame 17 also has the function of receiving the surplus of the injected lubricant, and a surplus lubricant receiving box 1 is provided at the bottom of the opening 18 provided on the bottom surface.
9 is arranged.

As shown in Figures 1 and 6, the lubricant application member is made of a material that can withstand high temperatures and is formed in a state in which it is easily impregnated with lubricant. Individual scrubbers 20a
A large number of... are prepared, and each is arranged radially to form a ring shape to form the stainless steel scrubber 20.

The stainless steel wire 21 is passed through the ring of each scrubbing brush 20a and fixed so that the ring-shaped inner diameter is large enough to elastically contact the punch P. Further, a cylindrical fixing frame 22 is arranged around the outer periphery of the stainless steel scrubbing brush 20, and the individual scrubbers 20a are fixed to this using stainless steel wires 23. stainless steel scrubber 20
A lubricant injection nozzle C is fitted into the center of the ring. Further, the fixed frame 22 includes a substantially ring-shaped holding frame 24a,
24b, and this holding frame is attached to the mounting plate 25.
It is connected to the conveying device E via.

The transport device E for lubricant application members is as shown in Figures 1 to 3 (5), and has two parallel guide rods 27a and 27b erected on a fixed gate-shaped frame 26. For example, it is supported by a hydraulic cylinder 2B. At the tip of the ram 28a of the hydraulic cylinder 28, a guide rod 27a,
A movable frame 29 that can be moved up and down by sliding on 27b is connected. Two guide rods 30a, 301) pass through the movable frame 29 so as to be slidable in the horizontal force direction, and a hydraulic cylinder 31, for example, is attached to the movable frame 29 so that its ram 31a can be freely extended in the horizontal direction. A mounting plate 25 for a lubricant application member is connected to the tip of the ram 31a, and the tips of the guide rods 30a and 30b are fixed to this mounting plate.

Next, the operation of applying lubricant to the punch P will be explained. As shown in the first figure, the lubricant supply pump B is operated in a state in which the lubricant application member is located within the frame 17 and the lubricant injection nozzle C is located at the center of the ring. The piston 5 shown in FIG. 4 rises from the lower position, so that the lubricant in the storage chamber 9 is discharged from the discharge port 10b and sent to the injection nozzle C through the pipe 13(6). Lubricant is in the center hole 15
a, from 16a to the recess 15c through the communication hole 16c...
, the stainless steel scrubber 20 is applied from the gap 17 in all directions.
It blows towards you. Since the stainless steel scrubbing brush 20 has sufficient impregnating properties, it is sufficiently impregnated with lubricant, but the excess lubricant drips onto the frame 17 and flows out from the opening 18 into the receiving box 19 and is stored therein. Then, the hydraulic cylinder 28 is operated to move the ram 28a forward slightly and raise it to the movable frame 29. Then, the hydraulic cylinder 31 is operated to move the ram 31a forward in the horizontal direction. In this position, the lower end of the punch P is positioned below the punch P like a lubricant application member, and the lower end of the punch P faces the center of the ring of the stainless steel scrubber 20. Then, the hydraulic cylinder 28 is operated again, and the ram 28
27b for advancing a is slid and moved upward, and during this time, the punch is fitted into the ring of the stainless steel scrubber 20, and the scrubber comes into elastic contact with the outer periphery of the punch, and then rises from D to D. For this reason, the lubricant impregnated in the scrubbing brush 20 oozes out and adheres to the outer peripheral surface of the punch.

Next, operate the hydraulic cylinder 28 in the opposite direction to release the ram 2.
When the movable frame 8a is moved backward, the movable frame is lowered, the hydraulic cylinder 31 is actuated to move the ram 31a backward, and the hydraulic cylinder 28 is actuated again to further move the ram 28a back, so that the movable frame is moved back as shown by the solid line in FIG. Return to position.

After the desired forging process is performed by operating the punch P, when the punch returns to the original position shown by the solid line in FIG. 1, the lubricant is applied to the punch again by the above-described operation.

When adjusting the amount of lubricant sprayed, the threaded portion 8b is raised or lowered by tightening or loosening the nut 12 shown in FIG. As a result, the volume of the lubricant storage chamber 9 at the position where the piston rod 8 is lowered decreases or increases.

In other words, the amount of lubricant stored changes. Since the stored amount corresponds to the amount of lubricant sprayed once to the lubricant application member, the amount of lubricant sprayed is adjusted depending on the amount of lubricant coming off.

As described above, according to the present invention, when applying lubricant to a punch, there is no need to rely on manual labor, and unmanned operation is possible, improving efficiency. In addition, since the amount of lubricant to be sprayed can be adjusted, waste can be eliminated, the lubricant can be applied uniformly to the outer peripheral surface of the punch, and there are many excellent effects such as being safe without the risk of fire.
