Description

Technical Field

[0001] The utility model relates to the technical field of screw processing, in particular to a nail feeding device for a thread rolling machine. Background Art

[0002] A thread rolling machine is a processing equipment that plastically deforms metal blanks through a thread rolling plate. It is a non-cutting processing method and is suitable for processing external threaded workpieces such as screws. When processing screws and other workpieces, they generally need to enter the thread rolling machine in a vertical state. Therefore, corresponding devices will be used to limit the unformed screws.

[0003] Authorization announcement No. CN207996964U discloses an automatic feeding device for a thread rolling machine, including a guide rail forming a feed track, a guide block arranged on a workbench, a feed track formed between the guide block and the guide rail, and also including a pushing assembly, a block fixed on the guide rail and forming a material passing space between the block and the guide rail, the end of the block away from the guide rail is located above the guide block, and the distance between the block and the upper surface of the guide block is greater than the thickness of the nut plus the elastic washer and the flat washer of the screw and is less than the length of the screw rod; the utility model has the following advantages and effects: the block on the guide rail can prevent the screw from bouncing, reduce the accumulation of screws on the workbench, and enable the pusher plate to smoothly feed the screw into the thread rolling mechanism for thread rolling, thereby achieving the purpose of improving the production efficiency of the screw.

[0004] The existing thread rolling machine nail feeding device can limit the workpiece so that it enters the thread rolling machine in a vertical state, but the limiting component cannot be adjusted according to the specific specifications of the screw. The only option is to replace the corresponding limiting component when processing screws of different specifications, which affects the processing efficiency. Summary of the Invention

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A nail feeding device for a thread rolling machine includes a U-shaped plate with an open top and a limit plate. The limit plate is located at the top of the U-shaped plate. Bearings are fixedly installed on the two end surfaces of one side of the limit plate through reserved grooves. Adjustment screws are installed on the top surfaces of both sides of the U-shaped plate through reserved threaded holes. One end of the adjustment screw is fixed in the rotating circle of the bearing.

[0008] Furthermore, a through groove is provided on the surface of one end of the bottom inner portion of the U-shaped plate, a pad is inserted into the through groove, a bottom plate is fixedly installed on the bottom of the pad, both side surfaces of one end of the bottom of the U-shaped plate are glued and connected with magnet blocks through reserved grooves, and the magnet blocks are used to adsorb and fix the bottom plate, and a baffle is fixedly installed on the end of the U-shaped plate close to the through groove.

[0009] Furthermore, through holes are provided on both side surfaces of the top of the baffle, and insertion rods are inserted into the through holes, and a positioning plate is fixedly installed on the top of the insertion rod.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1 When the screw is inserted into the U-shaped plate 1, the top cover of the screw cannot pass through the gap, and the rod body of the screw can be located in the gap so that the screw can slide in the gap in a vertical state until it enters the interior of the thread rolling machine.

[0020] Among them, Figure 1 、 2 As shown in Figure 3, a through groove 13 is provided on the surface of one end of the bottom of the U-shaped plate 1, and a pad 14 is inserted into the through groove 13. A bottom plate 6 is fixedly installed on the bottom of the pad 14. Both side surfaces of one end of the bottom of the U-shaped plate 1 are glued with magnet blocks 12 through reserved grooves. The magnet blocks 12 are used to adsorb and fix the bottom plate 6. A baffle 8 is fixedly installed on the end of the U-shaped plate 1 close to the through groove 13. When a nail falls into the U-shaped plate 1, since the U-shaped plate is in an inclined state, the nail will be concentrated in the through groove 13 under the action of gravity. Therefore, a person can apply force to the bottom plate 6, so that the magnet block 12 no longer adsorbs the bottom plate 6, and the pad 14 no longer blocks the through groove 13, so that the nail can be moved out of the U-shaped plate 1 through the through groove 13.

[0021] Among them, Figure 1 、 3 The top two side surfaces of the baffle 8 are provided with through holes 9, and a rod 10 is inserted into the through hole 9. A positioning plate 11 is fixedly installed on the top of the rod 10. People can insert the rod 10 into the through hole 9 to increase the height of the baffle 8.

[0022] Among them, Figure 1 As shown, support screws 5 are installed on the two end surfaces of the bottom of the limit plate 4 through reserved threaded holes. When the position of the limit plate 4 is determined, personnel can use tools such as wrenches to rotate the support screws 5 so that their bottoms rest against the U-shaped plate 1 to support the limit plate 4.

[0023] Among them, Figure 1As shown, connection holes 7 are provided on the surfaces of both ends of the U-shaped plate 1 , and personnel can connect and fix the U-shaped plate 1 to the corresponding mechanism through the connection holes 7 .

[0024] It should be noted that the present invention is a nail feeding device for a thread rolling machine. When working, personnel can fix the device at an angle on the feed port of the thread rolling machine, and make the end of the U-shaped plate 1 located at a higher position be connected to the discharge port of the vibration disk. Next, personnel can manually rotate the two adjusting screws 2 at the same time according to the specifications of the screws to be processed. Since the two adjusting screws 2 are connected to the limit plate 4 through the bearing 3, and the limit plate 4 is limited by the two adjusting screws 2 and cannot rotate, when the two adjusting screws 2 rotate, the limit plate 4 will move, so that the gap between the limit plate 4 and the side wall of the U-shaped plate 1 meets the requirements, and then when the vibration disk makes the screw enter the U-shaped plate 1, the top cover of the screw cannot pass through the gap, and the rod body of the screw can be located in the gap, so that the screw slides in the gap in a vertical state until it enters the interior of the thread rolling machine for thread rolling operation.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
