[0035] like Figure 1 As shown, an embodiment of the utility model provides an advance and retract device for a flat-head thread rolling machine, including a chassis 1, and a plurality of legs 101 are installed on the lower end surface of the chassis 1. Specifically, in this embodiment, four legs 101 are provided and distributed at the four corners of the lower end surface of the chassis 1 to support the chassis 1.

[0036] A flat head thread rolling machine body 3 is installed on the chassis 1. Specifically, a fixing frame 2 is fixed to the middle of the flat head thread rolling machine body 3, a fixing block 201 is fixed to the bottom of the fixing frame 2, and two fixing rods 102 are symmetrically fixed on both sides of the upper end surface of the chassis 1, and both ends of the fixing block 201 are distributed and sleeved and fixed on the two fixing rods 102, so that the fixing block 201 is detachably fixed to the middle of the upper end surface of the chassis 1, that is, the flat head thread rolling machine body 3 is detachably fixed to the chassis 1, which is convenient for later disassembly and assembly.

[0037] like Figure 1 and Figure 2 As shown, a feed hole 301 is provided in the middle of one end of the flat head thread rolling machine body 3, and a fixing plate 4 is arranged on the side of the feed hole 301 away from the flat head thread rolling machine body 3, and a plurality of fixing screws 401 are fixed to the edge of the fixing plate 4 to fix to the end of the flat head thread rolling machine body 3, and a feed and retract mechanism 5 is detachably fixed in the middle of the fixing plate 4.

[0038] The knife advance and retreat mechanism 5 includes a driving assembly 501, and the driving assembly 501 includes a driving motor and a reduction motor. The reduction motor is installed at the output end of the driving motor, and an output tube 502 is provided at the output end of the reduction motor. An elastic member 503 is provided in the output tube 502. One end of the elastic member 503 is connected to a screwdriver rod 504 for inserting into the feed hole 301, and a knife body 505 is fixed to one end of the screwdriver rod 504 that inserts into the flat-head thread rolling machine body 3 through the feed hole 301. Therefore, in this device, the knife advance and retreat is realized by adding an elastic member 503 to the driving assembly 501, one end rotates and the other end is stationary, realizing the automatic knife advance and retreat function within the range of 3-7 cm, reducing manual intervention, and improving the convenience and safety of operation. In addition, the flat-head knife is directly driven by the main motor of the flat-head thread rolling machine body 3, ensuring the stability and accuracy of power transmission.

[0039] In this embodiment, the above-mentioned drive motor can be selected but not limited to a DC permanent magnet motor with a model of 702T57-6385 and specifications of 24VDC voltage, 4A current, 70W power, and 1500PIM speed.

[0040] In addition, in other embodiments, the driving component 501 may also use an electric push rod, and its model may be selected from but is not limited to the 50mm stroke electric push rod of MS6000-50-207-8-3000-24.

[0041] In a specific implementation, the elastic member 503 may be selected from but not limited to a nitrogen spring balance, which can be used to play a certain buffering role when the screwdriver rod 504 drives the cutter body 505 to feed, and can effectively prevent the cutter body 505 from collapsing.

[0042] like Figure 3 and Figure 4As shown, a fixing seat 6 is fixed to one side of the driving component 501 facing the middle of the fixing plate 4, a positioning block 7 is fixed to the middle of the side of the fixing seat 6 away from the driving component 501, and a groove for the positioning block 7 to be embedded is opened in the middle of the fixing plate 4, and a card slot is extended at the bottom of the groove, and two movable plates 8 are symmetrically inserted on both sides of the fixing seat 6, and one end of the movable plate 8 inserted into the fixing seat 6 is connected to a limiting plate 9 parallel to it, and the limiting plate 9 is located in the positioning block 7 and extends from both sides of the positioning block 7, so that after the positioning block 7 is inserted into the groove in the fixing plate 4, it can also be fixed by using the card slot in the groove where the limiting plate 9 is inserted.

[0043] During specific implementation, a movable cavity 601 is opened in the middle of the fixed seat 6, and the two movable plates 8 are inserted into the movable cavity 601, and a return spring 10 is installed between the two movable plates 8. The return spring 10 elastically abuts the movable plate 8 to extend out of the outer side of the fixed seat 6, and the return spring 10 elastically abuts the limit plate 9 to extend out of the outer side of the positioning block 7.

[0044] The working process of the utility model technical solution is as follows:

[0045] When in use, the flat-head thread rolling machine advance and retract device is directly connected to the control knife body 505 by setting a drive component 501, an elastic member 503 and a screwdriver rod 504 to achieve automatic advance and retract operations within the range of 3-7 cm. There is no need for cumbersome manual adjustments, and it is convenient to cooperate with the main motor to directly drive the flat-head knife, thereby ensuring the stability of power transmission. In combination with the above-mentioned automated advance and retract mechanism 5, it can greatly improve the convenience and safety of operation.

[0046] At the same time, the disassembly and assembly of the driving component 501 on the fixed plate 4 can be controlled by pressing the movable plate 8 to control the extension and retraction of the limit plate 9 on both sides of the positioning block 7, so as to fix the fixing seat 6 at the end of the driving component 501 to the fixed plate 4, that is, the driving component 501 is fixed to the fixed plate 4. Conversely, the driving component 501 can be removed, which is conducive to the rapid disassembly and assembly and maintenance of the automated advance and retract mechanism 5 in the later stage, and is easy to use.

[0047] In summary, the present device can not only automatically advance and retract the knife within a certain centimeter range without complicated manual adjustment, but also facilitates the rapid disassembly and assembly of the advance and retract mechanism 5 at a later stage, which is conducive to inspection and maintenance, and is safe and convenient to use as a whole.
