Description

TECHNICAL FIELD

[0001] The present invention relates to a thread rolling machine design, in particular to a thread rolling machine capable of avoiding mutual mixing of oil. BACKGROUND

[0002] Referring to Figure 1 The prior art thread rolling machine 1 (schematically shown in the figure) comprises a machine table 11, a cutting fluid supply device 12, a lubricating oil supply device 13 and a driving device 14 arranged on the machine table 11, a movable die plate 15 arranged on the driving device 14, a fixed die plate 16 arranged on the machine table 11 and opposite to the movable die plate 15, and a cover device 17; wherein the driving device 14 has a rotating member 141 arranged on the machine table 11 and driven by power, and a connecting member 142 connected with the rotating member 141 and extending outward, the connecting member 142 is arranged with the movable die plate 15, the cutting fluid supply device 12 can supply cutting fluid to the movable die plate 15 for thread rolling operation, the lubricating oil supply device 13 supplies lubricating oil for the lubricating operation required by the driving device 14, and the cover device 17 has a cover 171 capable of covering the rotating member 141, and a sliding cover 172 arranged at one end of the connecting member 142, the cover 171 forms a containing space 171a for containing the rotating member 142, and an opening 171b is formed on the cover 171 for the sliding cover 172 to slide in and out, so that the sliding cover 172 slides with the connecting member 142 and passes through the opening 171b.

[0003] During high-speed thread rolling operation, the cutting fluid supplied to the movable die plate 15 and the fixed die plate 16 can cool the blank (not shown in the figure), the movable die plate 15 and the fixed die plate 16, so as to avoid the influence of high temperature on the thread rolling operation, and the lubricating oil supplied by the lubricating oil supply device 13 to the driving device 14 during operation can effectively prevent friction and wear between components under load connection, so as to maintain the service life of the thread rolling machine 1 and enable the thread rolling machine 1 to quickly form the blank into a thread by smooth thread rolling operation.

[0004] However, it is found that the cutting fluid supplied on the movable die plate 15 will be splashed randomly when the movable die plate 15 is operated at high speed, and the cutting fluid will adhere to the sliding cover 172. When the connecting member 142 moves back and forth at high speed, the cutting fluid will be brought into the shield 171, and the adhered cutting fluid will be separated and fall into the accommodating space 171a due to the centrifugal force generated by the high-speed displacement of the connecting member 142. The cutting fluid adhered to the inside and outside of the machine table 11 and the shield 171 will be dirty, and the cutting fluid will be mixed with the lubricating oil flowing on the rotating member 141, which will deteriorate the lubricating oil and greatly reduce the lubricating effect of the lubricating oil. In addition, the service life of the thread rolling machine 1 will be affected, which needs to be improved. SUMMARY

[0005] Therefore, the purpose of the present application is to provide a thread rolling machine which can collect cutting fluid and lubricating oil separately to avoid the mixing of the cutting fluid and the lubricating oil during use, so as to effectively maintain the quality of the lubricating oil in use.

[0049] The foregoing and other technical contents, features and effects of the present application will become more apparent from the following detailed description of a preferred embodiment, taken with the accompanying drawings.

[0050] Reference is made to Figure 2In a preferred embodiment of the present application, the thread rolling machine 3 (schematically shown in the figure) comprises a machine table 31, a cutting fluid supply device 32, a lubricating oil supply device 33 and a driving device 34 arranged on the machine table 31, a movable thread plate 35 connected to the driving device 34, a fixed thread plate 36 arranged on the machine table 31 and opposite to the movable thread plate 35, a cover device 37 arranged on the machine table 31, and a collecting groove 38 arranged on the machine table 31. The driving device 34 comprises a rotating member 341 arranged on the machine table 31 and driven by a power source, and a connecting member 342 (part of the connecting member is shown by a dashed line in the figure) connected to the rotating member 341 and extending outward. The connecting member 342 is arranged for the movable thread plate 35. The cutting fluid supply device 32 supplies cutting fluid to the movable thread plate 35 for thread rolling operation, and the lubricating oil supply device 33 supplies lubricating oil to the rotating member 341 for lubrication.

[0051] In addition, the cover device 37 comprises a cover 371 for covering the rotating member 341, and a sliding cover 372 arranged at one end of the connecting member 342. The cover 371 forms a receiving space 371a for receiving the rotating member 341. An opening 371b is formed on the cover 371 for the sliding cover 372 to slide in and out. A scraping member 371c is arranged around the opening 371b. The scraping member 371c is arranged in a multi-point contact mode with the sliding cover 372. The collecting groove 38 is arranged below the connecting member 342. One side of the collecting groove 38 is arranged in the receiving space 371a, and the other side extends outside the cover 371. In this embodiment, the sliding cover 372 extends downward relative to one side of the collecting groove 38, and forms a first blocking member 372a and a second blocking member 372b arranged in a spaced apart mode. The first blocking member 372a and the second blocking member 372b are arranged inside and outside the collecting groove 38, respectively, as shown in the figure. Figure 3

[0052] Referring to Figure 2 , Figure 4a , Figure 4b ​When the thread rolling machine 3 is started to perform the thread rolling operation, the rotating member 341 is driven to rotate, and the connecting member 342 is driven to reciprocate by the rotating member 341. At this time, the movable die plate 35 is driven to reciprocate relative to the fixed die plate 36 by the connecting member 342. Meanwhile, the feeding device (not shown) on one side of the machine table 31 feeds the blank to the space between the movable die plate 35 and the fixed die plate 36. The blank is rolled into a thread by the movable die plate 35. At the same time, the cutting fluid supply device 32 sprays cutting fluid between the movable die plate 35 and the fixed die plate 36 to reduce the temperature generated by the thread rolling operation. The iron filings generated by the thread rolling operation are mixed with the cutting fluid and flow downward with the cutting fluid. The cutting fluid is sprayed on the sliding cover 372 during the reciprocating movement of the movable die plate 35. The cutting fluid is scraped off the sliding cover 372 by the scraping member 371c when the sliding cover 372 slides rapidly through the opening 371b into the cover 371. The cutting fluid is collected by the collecting groove 38 below the connecting member 342 when the cutting fluid falls downward after being scraped off. The first blocking member 372a is arranged in the collecting groove 38 to prevent the cutting fluid from splashing into the accommodating space 371a. The cutting fluid is effectively limited in the collecting groove 38 to prevent the cutting fluid from mixing with the lubricating oil used by the rotating member 341.

[0053] Of course, while the cutting fluid supply device 32 supplies cutting fluid for cooling, the lubricating oil supply device 33 also supplies lubricating oil for reducing friction to the driven components at the same time, so as to effectively reduce the friction heat generated between the components in motion, to reduce the friction heat between the rotating member 341 and the connecting member 342 in motion, so that the rotating member 341 is lubricated during the driving operation and the generated friction heat is also removed in time, effectively preventing friction and wear between the components under load connection. The lubricating oil supplied to the rotating member 341 will be sprayed around under the rapid transmission of the components, which can not only be prevented from splashing out of the machine 31 by the blocking of the cover 371, but also be effectively blocked by the second blocking member 372b located outside the collection groove 38, so as to prevent the lubricating oil from mixing with the cutting fluid collected in the collection groove 38. The first blocking member 372b located in the collection groove 38 can block the cutting fluid that slides and splashes outward, which can eliminate the factors of mutual mixing and deterioration of the cutting fluid and the lubricating oil. Therefore, the design of the scraping member 371c can effectively scrape the cutting fluid splashed on the sliding cover 372 to prevent the cutting fluid from being brought into the cover 371, and the collection groove 38 is located below the connecting member 342 to effectively collect the scraped cutting fluid to avoid the machine 31 being dirty and difficult to clean. At the same time, the sliding cover 372 has the first blocking member 372a and the second blocking member 372b located in the collection groove 38 inside and outside, respectively, to effectively block and intercept the splashed cutting fluid and lubricating oil, respectively, so as to effectively maintain the quality of the cutting fluid and the lubricating oil used respectively, and to avoid the use of deteriorated lubricating oil on the threading machine 3, thereby prolonging the service life of the threading machine 3.

[0054] In summary, the thread rolling machine of the present application has a collecting groove below the connecting member, and two first and second blocking members arranged on the connecting member and extending downward from the side of the collecting groove. The first and second blocking members are arranged inside and outside the collecting groove, respectively. The cutting fluid used for cooling during thread rolling is collected by the collecting groove, so that the cleanliness of the machine is effectively maintained. The first and second blocking members are arranged inside and outside the collecting groove, respectively, so that the cutting fluid and lubricating oil that may be splashed are effectively blocked. The cutting fluid and lubricating oil are not mixed, and the quality of the cutting fluid and lubricating oil is maintained, so that the service life of the thread rolling machine is prolonged.

[0055] The above description is only a preferred embodiment of the present application, and cannot limit the scope of the present application. Any simple equivalent changes and modifications made according to the scope of the present application and the content of the specification should still be within the scope of the present application.
