Lubrication application method

Abstract

To provide a lubrication application method that can spray lubricant even on irregularly shaped parts. To provide a lubrication application method that allows arbitrary control of the spraying range. [Solution] The lubrication application method involves placing a workpiece 20 near a lubrication device 10 that includes lubrication nozzles 11-1 and 11-2 for spraying lubricant and a rotary servo that rotates the lubrication nozzles 11-1 and 11-2 with the spray shaft as the axis of rotation. The lubrication device 10 is advanced to the spraying position of the workpiece 20, and the lubrication nozzles 11-1 and 11-2 are rotated by the rotary servo, while lubricant is sprayed from the lubrication nozzles 11-1 and 11-2 to apply lubricant to the workpiece 20.

Description

Technical Field

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, forging presses are general-purpose equipment that produces a variety of products. At that time, since the shape of the mold fixed to the press varies greatly depending on the product, there was a problem that the number of lubricating nozzles for spraying the lubricating liquid onto the mold also increased during continuous production.

Means for Solving the Problems

[0005] A lubricating application method according to an embodiment is configured such that the lubricating nozzle has a rotation mechanism.

Effects of the Invention

[0006] According to the lubricating application method of the present disclosure, a lubricant can be sprayed even on a shaped part. Further, according to the lubricating application method of the present disclosure, the spraying range can be arbitrarily controlled.

Brief Description of the Drawings

[0007] [Figure 1] This is a cross-sectional view showing an example of a lubrication device used in the lubrication application method according to Embodiment 1. [Figure 2] This is a cross-sectional view showing the operation of a lubrication device used in the lubrication application method according to Embodiment 1. [Figure 3] This is a cross-sectional view showing an example of the spraying range of the lubrication application method according to Embodiment 1. [Modes for carrying out the invention]

[0008] Embodiment 1 Embodiments of the present invention will be described below with reference to the drawings. Figure 1 is a cross-sectional view showing an example of a lubrication device used in the lubrication application method according to Embodiment 1.

[0009] In Figure 1, the lubrication device 10 includes lubrication nozzles 11-1 and 11-2, a joint section 12, rotary servos 13-1 and 13-2, a hose joint 14, hoses 15-1, 15-2 and 15-3, electrical wiring and air hoses 16-1 and 16-2.

[0010] Lubrication nozzles 11-1 and 11-2 are nozzles that spray lubricating oil.

[0011] The joint section 12 is a joint that connects the rotary servos 13-1 and 13-2 to the hoses 15-2 and 15-3.

[0012] Rotary servos 13-1 and 13-2 are servo motors that rotate lubrication nozzles 11-1 and 11-2, respectively. Rotary servo 13-1 rotates lubrication nozzle 11-1 using the injection shaft 17 of lubrication nozzle 11-1 as its axis of rotation. Rotary servo 13-2 rotates lubrication nozzle 11-2 in the same manner.

[0013] Hose joint 14 is a joint that connects hose 15-1 with hoses 15-2 and 15-3.

[0014] Hoses 15-1, 15-2, and 15-3 are hoses for supplying lubricating oil.

[0015] The electrical wiring and air hoses 16-1, 16-2 are the electrical wiring and air hoses for operating and controlling the rotary servos 13-1, 13-2. The electrical wiring and air hoses 16-1, 16-2 have a length greater than the amount of rotation (extra length) and are of a length that does not interfere with rotation.

[0016] Next, the operation of the lubricating device in the lubricating application method will be described. FIG. 2 is a cross-sectional view showing the operation of the lubricating device used in the lubricating application method according to Embodiment 1.

[0017] First, as shown in FIG. 2A, the molded work 20 is placed near the lubricating nozzles 11-1, 11-2 of the lubricating device waiting at the position before spraying.

[0018] Next, as shown in FIG. 2B, the lubricating device 10 advances to the spraying position of the work 20. After advancing the lubricating device 10 to the predetermined spraying position, the lubricant is sprayed and the lubricating nozzles 11-1, 11-2 in FIG. 1 are rotated.

[0019] After spraying is completed, the lubricating device 10 is replaced. Through the above operations, the lubricant is sprayed.

[0020] Next, the spraying range of the lubricating application method will be described. FIG. 3 is a cross-sectional view showing an example of the spraying range of the lubricating application method according to Embodiment 1.

[0021] As shown in FIG. 3A, when the lubricating nozzles 11-1, 11-2 are rotated respectively, the direction in which the lubricant is sprayed becomes conical with respect to the spray axis.

[0022] Therefore, the lubricant applied to the work 20 is in the range surrounded by the dotted lines in FIGS. 3B and 3C.

[0023] Thus, according to the lubrication application method of Embodiment 1, the degree of freedom in the spraying area is greatly increased, and it is possible to spray the entire circumference at most. Therefore, even if there are many irregularly shaped parts, the lubrication equipment can be shared, and the amount of capital investment can be reduced. In addition, by sharing the lubrication equipment, the installation space can be reduced. Furthermore, optimal spraying can be performed on parts with complex shapes.

[0024] It should be noted that the present invention is not limited to the embodiments described above, and can be modified as appropriate without departing from the spirit of the invention. For example, the rotation angle of the lubrication nozzle can be set arbitrarily so that it is sprayed only on the necessary parts. [Explanation of Symbols]
