Description

Technical Field

[0001] The invention relates to a screw thread rolling machine, in particular to a screw thread rolling machine with a cooling device. Background Art

[0002] See Figure 1 The existing screw thread rolling machine 1 includes a machine table 11, a feed track 12 arranged on the machine table 11 and inputting a blank 2, a thread rolling device 13 arranged on the machine table 11 and rolling the blank 2 into shape, and a transmission device 14 driving the thread rolling device 13 to move in conjunction; wherein, the machine table 11 has a base 111 for the thread rolling device 13 to be installed, and a transmission box 112 arranged next to the base 111 and for the transmission device 14 to be installed; in addition, the thread rolling device 13 has a movable tooth plate 132 that can slide on the base 111, and a fixed tooth plate 131 provided on the base 111 and arranged opposite to the movable tooth plate 132. When the screw thread rolling machine 1 is actuated, it conveys the blanks 2 one by one to the thread rolling device 13 via the feed track 12, and drives the movable tooth plate 132 to move via the transmission device 14, so that the blanks 2 are rolled between the movable tooth plate 132 and the fixed tooth plate 131 to form a finished screw.

[0003] However, after actual use, it was found that during the thread rolling process of the thread rolling device 13, the blank 2 was subjected to strong squeezing and rubbing forces between the movable thread plate 132 and the fixed thread plate 131. In addition to the heat energy generated by the friction between them, the movable thread plate 132 was continuously driven at high speed by the transmission device 14, which also caused the machine 11 to generate high heat. The high heat caused the machine 11 to produce thermal expansion, affecting the accuracy of the thread rolling process of the movable thread plate 132. Relatively speaking, the quality of the blank after thread rolling is questionable. At the same time, when the temperature of the machine 11 is too high, it will also cause wear and tear, affecting the service life of the screw thread rolling machine, which needs to be improved.

[0059] The foregoing and other technical contents, features and effects of the present invention will be clearly understood in the following detailed description of the preferred embodiments with reference to the accompanying drawings.

[0060] See Figure 2 and Figure 3 In the first preferred embodiment of the present invention, the screw thread rolling machine 3 with a cooling device in this embodiment includes a machine table 31, a feed track 32 provided on the machine table 31 for feeding the blank 4, a thread rolling device 33 that slides on the machine table 31 and rolls the blank 4 into shape, a transmission device 34 that drives the thread rolling device 33 to move in a linked manner, and a cooling device 35 provided on the machine table 31; wherein, the machine table 31 is divided into a transmission area 311 for the transmission device 34 to be provided, and a table body area 312 for the thread rolling device 33 to slide, and the table body area 31 2 comprises a main body 3121 and a guard plate 3122 disposed on the main body 3121. Furthermore, the thread rolling device 33 comprises a movable thread plate 331 that is driven by the transmission device 34 and displaced on the main body 3121, and a fixed thread plate 332 disposed on the main body 3121 and opposite to the movable thread plate 331. For example, the main body 3121 supports the thread rolling device 33, and the guard plate 3122 is located above the main body 3121 and covers a portion of the thread rolling device 33 to protect the thread rolling device 33.

[0061] Continuing with the above, the cooling device 35 comprises a cooler 351, at least one flow channel 352 disposed in the platform area 312 and communicating with the cooler 351, a plurality of pipe units 353 respectively connecting the cooler 351 and the flow channel 352, and a liquid (not shown) flowing through the cooler 351, the flow channel 352 and the pipe unit 353; in addition, the cooler 351 comprises a cooling body 3510, and an input port 3511 and an output port 3512 disposed on the cooling body 3510 for inputting and outputting the liquid, and the above-mentioned The liquid can actually be a coolant. The cooling body 3510 can reduce the temperature of the liquid and connect the output port 3512 of the pipe unit 353 to the circulation channel 352 to input the liquid into the circulation channel 352. The liquid passes through the circulation channel 352 and is then transported to the input port 3511 through the pipe unit 353, so that a circulation is generated between the circulation channel 352 and the cooler 351, and the liquid is output through the cooler 351 to the pipe unit 353 and flows into the circulation channel 352 for heat exchange and flow. In this embodiment, it can be as follows Figure 3 The flow channel 352 can be set on the platform 3121, as shown in FIG. Figure 4 The flow channel 352 is provided on the guard plate 3122, or can be Figure 5 The flow channels 352 may be provided on both the platform 3121 and the guard plate 3122, and the pipe unit 353 is connected to each flow channel 352. Furthermore, the pipe unit 353 is also connected to the input port 3511 and the output port 3512 of the cooling body 3510, so that after the liquid is discharged through the cooling body 3510, it enters the flow channels 352 in sequence through the pipe unit 353 and then flows back to the cooling body 3510. In the following description of this embodiment, the flow channels 352 may be provided on the platform 3121 as an example.

[0062] See Figure 2 、 Figure 3When the screw thread rolling machine 3 is actuated, the blanks 4 are transported one by one into the thread rolling device 33 via the feed track 32, and the movable tooth plate 331 is driven to move by the transmission device 34, so that the blank 4 is threaded between the movable tooth plate 331 and the fixed tooth plate 332. During the process, when the movable tooth plate 331 is repeatedly displaced on the table body 3121 quickly, the heat generated by the movable tooth plate 331 and the fixed tooth plate 332 squeezing the blank 4 will be conducted to the table body 3121 and the guard plate 3122. Due to the design of the cooling device 35, the blank 4 is threaded between the movable tooth plate 331 and the fixed tooth plate 332. The flow channel 352 is provided in the body 3121. After the liquid is cooled by the cooling body 3510, it is input into the flow channel 352. The liquid can circulate in the flow channel 352 for heat exchange, thereby effectively lowering the temperature of the body 3121. As a result, the temperature of the guard plate 3122 and the thread rolling device 33 disposed adjacent to the body 3121 can be lowered. This effectively prevents the thermal expansion effect caused by overheating, which would affect the smoothness and accuracy of the thread rolling operation of the thread rolling device 31, and further increases the service life of the screw thread rolling machine 3.

[0063] See Figure 6 In the second preferred embodiment of the present invention, the screw thread rolling machine 3 with a cooling device in this embodiment still includes a machine table 31, a feed track 32 provided on the machine table 31 for inputting the blank 4, a thread rolling device 33 that slides on the machine table 31 and threads the blank 4, and a transmission device 34 that drives the thread rolling device 33 to move in a linked manner, and a cooling device 35 provided on the machine table 31 and other components. The aforementioned components and the effects to be achieved are the same as those in the first embodiment and will not be described in detail. In particular, in this embodiment, a first collecting tank 313 and a second collecting tank 314 for storing cutting fluid and lubricating oil are respectively provided below the machine table 31. , and the pipeline unit 353 is connected to the input port 3511 of the cooler 351 and the second collecting tank 314, so that the liquid becomes the lubricating oil to serve as a cooling medium, and the circulation channel 352 flows into the second collecting tank 314. At the same time, in this embodiment, the liquid flows through the cooling body 3510 and the circulation channel 352 and is input to the transmission area 311, and then flows from the transmission area 311 into the second collecting tank 314 for heat exchange and cooling effect. Since the liquid is lubricating oil passing through the cooling body 3510, the temperature of the lubricating oil can be reduced, and the deterioration of the lubricating oil due to high temperature can be reduced. Alternatively, it can be as follows Figure 7The transmission area 311 has a transmission box 3110 for the transmission device 34 to be installed, and a heat dissipation channel 3111 formed in the wall of the transmission box 3110. At the same time, a circulation channel 352 can be formed in the guard plate 3122. The aforementioned pipe unit 353 is connected to the at least one circulation channel 352 and the heat dissipation channel 3111, so that the lubricating oil flows through the cooler 351, the at least one circulation channel 352, the heat dissipation channel 3111, and then enters the second collecting tank 314. The aforementioned circulation channels 352 are connected to the at least one circulation channel 352 and the heat dissipation channel 3111. 52 is connected to the heat dissipation channel 3122, so that the lubricating oil flows through the cooler 351, the heat dissipation channel 3112, the circulation channels 352, etc., and finally enters the second collecting tank 314. Since the coolant is the lubricating oil passing through the cooler 351, the temperature of the lubricating oil can be reduced to prevent the lubricating oil from deteriorating. At the same time, the temperature of the guard plate 3122, the platform body 3121 and the transmission box 3110 can be reduced, so that the overall operating temperature of the screw rolling machine 3 can be reduced, thereby extending the overall service life of the screw rolling machine 3.

[0064] See Figure 8 In the fourth preferred embodiment of the present invention, the screw thread rolling machine 3 with a cooling device in this embodiment still includes a machine table 31, a feed track 32 provided on the machine table 31 for inputting blanks, a thread rolling device 33 that slides on the machine table 31 and rolls the blanks 4 into shape, and a transmission device 34 that drives the thread rolling device 33 to move in a linked manner, and a cooling device 35 provided on the machine table 31 and other components. The aforementioned components and the effects to be achieved are the same as those in the first embodiment and will not be described in detail. In particular, in this embodiment, the input port 3511 is connected to the first collecting tank 313 by the pipe unit 353, and the pipe unit 353 is connected to the input port 351 of the cooler 351. 511. The first collecting tank 313 converts the liquid into the cutting fluid, and inputs the cutting fluid into the cooling body 3510 through the pipe unit 353 to serve as a cooling medium; therefore, the cutting fluid is used as the liquid through the cooling device 35, and after the cutting fluid passes through the cooler 351 and is cooled, it is sequentially transported to the circulation channel 352 and the thread rolling device 33, which can simultaneously cool the circulation channel 352 and the thread rolling device 33. In addition to lowering the temperature of the table body 3121 and the thread rolling device 33, it can also lower the temperature of the cutting fluid, so that the temperature of the table body area 312 can be lowered, thereby extending the service life of the screw thread rolling machine 3.

[0065] In summary, the screw thread rolling machine with a cooling device of the present invention is designed such that the flow channel is provided in the table body or the guard plate, or in both the table body and the guard plate, and a cooler connected to the flow channel and capable of cooling a liquid; therefore, after the liquid is cooled by the cooler, the liquid is then introduced into the flow channel, where the liquid circulates in the flow channel for heat exchange, thereby lowering the temperature of the table body and the thread rolling device. This effectively prevents thermal expansion from affecting thread rolling accuracy and further extends the overall service life, thereby truly achieving the purpose of the present invention.
