[0031] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0032] The following is an explanation of the embodiments of the present invention through specific embodiments. Those skilled in the art can understand the advantages and effects of the present invention from the contents disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed in various ways based on different viewpoints and applications without departing from the concept of the present invention. In addition, the drawings of the present invention are only simple schematic illustrations and are not depicted according to actual sizes. It is stated in advance. The following embodiments will further explain the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the scope of protection of the present invention.

[0033] It should be understood that, although the terms "first", "second", "third", etc. may be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are mainly used to distinguish one component from another component, or one signal from another signal. In addition, the term "or" used herein may include any one or more combinations of the associated listed items depending on the actual situation.

[0034] See also Figure 1-2 , is a bolt thread rolling device of this embodiment; wherein the bolt thread rolling device comprises:

[0035] a feeder for accommodating a plurality of bolts to be processed;

[0036] The tooth-rubbing mechanism 1 comprises a first tooth-rubbing plate 11 and a second tooth-rubbing plate 12, wherein the first tooth-rubbing plate 11 and the second tooth-rubbing plate 12 are alternately arranged;

[0037] The pushing mechanism 2 includes a push rod, a push plate 21, and a push knife 22. The output end of the push rod is fixedly connected to the push plate 21, and the push plate 21 is fixedly connected to the push knife 22. The push rod is used to drive the push plate 21 to drive the push knife 22 to reciprocate between the first rubbing tooth plate 11 and the second rubbing tooth plate 12;

[0038] The feeding mechanism 3 includes a feeding seat 31 and a feeding pipe 32. The feeding seat 31 is arranged between the first rubbing plate 11 and the second rubbing plate 12. The feeding pipe 32 has a first end and a second end arranged opposite to each other. The first end of the feeding pipe 32 is connected to the feeder, and the second end of the feeding pipe 32 is connected to the top surface of the feeding seat 31. The middle section of the feeding pipe 32 has a through hole.

[0039] The dividing mechanism 4 includes a dividing knife 41, which has a first end and a second end that are relatively set. The first end of the dividing knife 4 is set in the direction of the through hole, and the second end of the dividing knife 4 is transmission-connected to the push plate 21 so that the first end of the dividing knife 4 can reciprocate along the direction of the through hole, so that the discharge pipe 32 passes through or is blocked by the dividing knife 4.

[0040] Through the above structure, when in use, the operator only needs to fill the feeder with a sufficient amount of bolts to be processed and start the feeder to allow the feeder to continuously transport the bolts to the feed pipe 32 of the feed mechanism 3. When one of the bolts passes through the feed pipe 32 and falls onto the feed seat 31, the dividing knife 41 in the dividing mechanism 4 pushes the falling bolt, so that the dividing knife 41 pushes the falling bolt into the processing area between the first rolling plate 11 and the second rolling plate 12. The second rolling plate 12 starts to run and rolls the above-mentioned bolts with the cooperation of the first rolling plate 11. Among them, during the travel of the dividing knife 41 pushing the knife, the dividing knife 41 in the dividing mechanism 4 is pushed out of the feeding tube 32 by the pushing plate 21. At this time, the feeding tube 32 is in a through state. Therefore, at this time, the last bolt in the feeding tube 32 falls to the top surface of the pushing knife 22 below and is temporarily supported by the top surface of the pushing knife 22. The vertical distance between the top surface of the pushing knife 22 and the dividing knife 41 in the feeding tube 32 can and can only accommodate a vertically placed bolt, so that only one bolt falls here. Then, the push rod returns, the pushing knife 22 and the dividing knife 41 are reset, so that the last bolt loses the support of the top surface of the pushing knife 22 and falls on the feeding seat 31, and the dividing knife 41 blocks the feeding tube 32 again. According to the above steps, the push rod and the thread rolling mechanism 1 continue to work in coordination to realize batch processing of a large number of bolts.

[0041] In the above process, since the dividing knife 41 works together with the push knife 22 under the indirect drive of the push rod, after each processing of one of the bolts, the feed pipe 32 is in a blocked state when the push rod returns, so that there is only one single bolt on the feed seat 31 directly connected to the rolling mechanism 1 at any time, which further avoids the possibility of multiple bolts falling into the area between the first rolling plate 11 and the second rolling plate 12 at the same time, avoids the situation where jamming affects production, and indirectly improves the processing efficiency of a large number of bolts.

[0042] It is worth noting that in the above structure, the vertical distance between the bottom surface of the feed tube 32 and the top surface of the feed base 31 can and only can accommodate one vertically placed bolt, that is, the feed tube 32 has a preset length to prevent the feed tube from obstructing the operation of the push knife 22. And whenever one of the bolts falls onto the top surface of the feed base 31, the bolt can be held up by at least part of the push knife 22, the first thread rolling plate 11 and the second thread rolling plate 12 so as not to fall over. In essence, the feed tube 32, the push knife 22, the first thread rolling plate 11 and the second thread rolling plate 12 form an independent closed space that can only lead to the thread rolling area for processing and is used to accommodate one bolt, thereby improving the processing stability.

[0043] Furthermore, the material dividing mechanism also includes a fixed seat 42, a guide column 43, a connecting plate 44, and an elastic component 45. The fixed seat 42 is installed on the discharge tube 32, and the guide column 43 passes through the fixed seat 42. The guide column 43 has a first end and a second end that are relatively arranged. The first end of the guide column 43 is fixedly connected to the connecting plate 44, and the connecting plate 44 is fixedly connected to the dividing knife 41. The second end of the guide column 43 is installed with an elastic component 45, and the second end of the guide column 43 is arranged toward the push plate 21, so that the push plate 21 pushes the push knife 22 to advance and pushes the guide column 43 at the same time, and the elastic component 45 is compressed. Synchronously, the first end of the guide column 43 drives the connecting plate 44 to drive the push knife 22 to leave the through hole, so that the discharge tube 32 is conductive; when the push plate 21 drives the push knife 21 to reset, synchronously, the elastic component 45 resets and drives the push knife 22 to reinsert into the through hole, so that the discharge tube 32 is blocked. Through the above structure, the push mechanism 2 including the push rod and other large-volume structures is set on one side of the thread rolling mechanism 1, and the material dividing mechanism 4 and the processing area of ​​the bolt are set on the other side of the thread rolling mechanism 1, and the structure is compact and the space utilization rate is good. At the same time, with the help of the elastic component 45 of the coil spring set at the first end position of the guide column 43, the material dividing mechanism 4 can be independent of the push mechanism 2. Whenever the push rod returns, the elastic force of the coil spring is used to automatically reset the material dividing knife 41. Compared with the method of directly fixing the special-shaped material dividing knife with the push plate 21, the stability of the structure is better and it is convenient for later maintenance.

[0044] Furthermore, the bolt thread rolling device also includes an adjustment mechanism 5, and the adjustment mechanism 5 includes an adjustment column 51 and an adjustment plate 52. The adjustment column 51 is fixed on one side of the first thread rolling plate 11, and the adjustment plate 52 has a first end and a second end that are relatively set. The adjustment column 51 is connected to the first end of the adjustment plate 52 by penetration, and the feed tube 32 is connected to the second end of the adjustment plate 52 by penetration. Specifically, the connection between the adjustment plate 52 and the adjustment column 51 is set as a waist hole, so that the adjustment plate 52 can adjust the horizontal position with the adjustment column 51 as a reference. The waist hole extends in the direction where the first end and the second end of the adjustment plate 52 are connected. The end of the adjustment column 51 passing through the waist hole is fixed by a nut with a diameter larger than the diameter of the waist hole. Specifically, the second end of the adjustment plate 52 has a gap for adjusting the tightness of the feed tube 32. At the same time, in this embodiment, it can be seen that Figure 1 The side of the gap has a screw hole connected to the gap, and the screw hole passes through both sides of the gap. After the feed tube 32 passes through the adjustment plate 52 and the angle is adjusted, it is tightened in the screw hole through an external fastener to tighten the gap and completely fix the angle of the feed tube 32.

[0045] By setting the above-mentioned adjustment mechanism 5, the operator can flexibly adjust the position and angle of the feeding mechanism 3 and the dividing mechanism 4 to adapt to the thread rolling mechanisms 1 of different specifications and sizes.

[0046] The contents disclosed above are only preferred feasible embodiments of the present invention, and are not intended to limit the scope of the present invention. Therefore, all equivalent technical changes made using the contents of the present invention's specification and drawings are included in the scope of the present invention.

[0047] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0048] Although the present application has been described through embodiments, those skilled in the art will appreciate that there are many modifications and changes to the present application without departing from the spirit of the present application. It is intended that the attached embodiments include these modifications and changes without departing from the present application.
