Detailed Description

In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1 to 5 together, a thread forming apparatus for a guide rod according to the present utility model will now be described. The thread forming device for the guide rod comprises a thread rolling wheel 1, a supporting seat 2, an angle adjusting component 3 and a driving component 4.

The thread rolling wheels 1 are arranged in two, parallel threads 101 are arranged on the thread rolling wheels 1, the two thread rolling wheels 1 are driven to rotate in the same direction, under the rotation state of the thread rolling wheels 1, a guide rod to be formed by threads is arranged between the two thread rolling wheels 1, and the two thread rolling wheels 1 are driven to clamp the guide rod. And a supporting seat 2 is arranged between the two thread rolling wheels 1, and the supporting seat 2 is used for supporting the guide rod.

Meanwhile, the two angle adjusting assemblies are arranged, the two angle adjusting assemblies 3 are respectively connected with the two thread rolling wheels 1, the angle adjusting assemblies 3 are used for adjusting the angles of the corresponding thread rolling wheels 1 along the extending direction perpendicular to the guide rod, and the angle adjusting assemblies 3 respectively drive the two thread rolling wheels 1 to incline along opposite directions on the vertical plane where the axes of the two thread rolling wheels are located. The driving assembly 4 is connected with the thread rolling wheel 1 and is used for driving the thread rolling wheel 1 to rotate.

In the thread forming device for the guide rod of the embodiment, the thread rolling wheels 1 of the parallel threads 101 are selected, and the two thread rolling wheels 1 are obliquely arranged in opposite directions on the vertical plane where the axes of the thread rolling wheels are located, so that the thread groove on the guide rod can be conveniently processed. Meanwhile, due to the extrusion effect between the two thread rolling wheels 1, the guide rod to be processed can be conveniently driven to move forwards, the guide rod can be conveniently conveyed and processed by self, and the auxiliary pushing process of workers is reduced.

First, referring to fig. 7 and 9, in the prior art, a thread groove is formed in a guide bar by using a thread rolling wheel with an oblique thread, and the guide bar is difficult to advance only by continuously rotating along with the thread rolling wheel during the thread groove forming process, so that only a certain length of the thread groove can be formed when the guide bar is processed by using the thread rolling wheel with an oblique thread (for example, the section a in fig. 9). If the length of the thread groove on the guide rod is to be increased, multiple groups of thread rolling wheels are coaxially arranged along the extending direction of the guide rod and simultaneously process the guide rod. However, this machining method has a problem that the positions of the ports of two adjacent thread grooves are not well connected.

In practical application, the length of the thread to be processed of the guide rod can reach several meters, tens of meters and even tens of meters, and theoretically, the length of the thread rolling wheel also reaches corresponding several meters, tens of meters and even tens of meters, but the mode occupies large space of a processing workshop, and the thread rolling wheel with the large length cannot be processed at the existing processing level; in addition, the length of the guide rod is different, and the guide rod has various specifications, even if the guide rod can be processed into the thread rolling wheels with various lengths, the thread rolling wheels with corresponding sizes are required to be replaced when the guide rods of each batch are processed, and the processing cost is greatly increased.

Or when the length of the thread groove on the guide rod is increased, the guide rod is conveyed by manual hand-held feeding, but in this way, the guide rod needs to be reworked again from the port of the thread groove after the first section of thread groove is machined. For example, as shown in fig. 9, after the guide bar of the section a is finished, a worker holds the guide bar and pushes the guide bar so that the end B of the guide bar, which is the initial end of the new section, is newly machined to form the thread groove. The operation steps of the process are complex, the machining efficiency is low, and the joint parts of the two sections of thread grooves are manually controlled by staff, so that the problem of poor joint is easy to occur, and the follow-up machining is influenced.

As shown in fig. 6 and 8, the two thread rollers 1 in the present embodiment are inclined in opposite directions, thereby enabling the thread grooves to be formed in the guide bar by the two thread rollers 1 during rotation. Because the two thread rollers 1 are provided with the parallel threads 101, the two thread rollers 1 are obliquely arranged to enable the parallel threads 101 in the two thread rollers 1 to have the inclination difference of front and back angles, so that the guide rod can be driven to move forwards when the guide rod is extruded by rotating the parallel threads 101 with two different angles in the rotation process of the thread rollers 1.

In the thread groove forming mode in this embodiment, two thread rolling wheels 1 can process extrusion forming thread grooves in the rotation process, and simultaneously can utilize the inclination between two thread rolling wheels 1 and extrusion force and thrust to the guide rod, and the guide rod is automatically driven to move forwards when the thread rolling wheels rotate. So can be convenient for make in the course of working, can be sustainable process the guide bar for the engageability of the screw groove of each part of guide bar is better.

In addition, in practical application, the guide rods with various specifications are applied, and based on the thread rolling wheel 1 in the embodiment, one thread rolling wheel 1 can be theoretically used to process guide rods with any specification, namely, the guide rods with the specifications of several meters, tens of meters and even tens of meters can be processed without replacing the thread rolling wheel 1 during production, and the length of the thread rolling wheel 1 is set to be 10 cm-50 cm and other conventional dimensions according to production experience; and the constraint of throwing places, equipment and the like is overcome, and under the complete ideal condition, a thread rolling wheel can be used for processing guide rods with infinite length.

In summary, compared with the prior art, the thread rolling wheel of the embodiment has the following advantages:

1. In the thread rolling process after the guide rod is charged, the guide rod can be automatically conveyed without manual assistance, so that the labor cost is saved, and the production efficiency is high;

2. The processing quality of the thread groove on the guide rod is stable and uniform, and the problem of unsmooth threaded connection is avoided;

Among them, since the thread roller 1 acts on the guide bar in the extrusion friction molding, sparks are easily generated between the thread roller 1 and the guide bar due to high temperature during the high-speed operation of the thread roller 1, and thus cooling is required during the operation of the apparatus. In this embodiment, a cooling system (not shown) is provided, wherein the cooling system preferably comprises a cooling box and a cooling pipe with one end connected to the cooling box, and the other end of the cooling pipe is positioned above the gap between the two thread rolling wheels 1 and used for supplying water to cool the contact part of the guide rod and the thread rolling wheels 1.

Generally, since the length of the guide bar is ten or more meters, the guide bar is too long when the guide bar is processed, which easily causes the guide bar to fall down, and affects the formation of the thread groove in the guide bar. Therefore, as a preferred embodiment, a through groove 40221 is formed in the gear case 4022 along the conveying direction of the guide rod, a sleeve is extended at the through groove 40221, and the processed guide rod part enters the sleeve and gradually passes out from the other end of the sleeve to be further lapped on the supporting frame at the end of the sleeve, so that the guide rod is ensured to be in a horizontal state, and the subsequent forming of the thread groove is facilitated.

In the thread forming device for the guide rod of the embodiment, in the use process, the driving motor 4023 is started, the driving motor 4023 drives the two thread rolling wheels 1 to synchronously rotate through the transmission assembly 402, and the guide rod arranged between the two thread rolling wheels 1 is extruded to form a thread groove while the thread rolling wheels 1 rotate. Further, since the two thread rollers 1 have a certain inclination angle therebetween, a forward pulling force is generated on the guide bar when the two thread rollers 1 rotate. Therefore, when the device is used for thread machining, the machining length of the guide rod can be not limited, and the guide rod can be subjected to thread machining in an unlimited manner, so that the auxiliary machining process of workers can be conveniently reduced, and the labor intensity of the workers is reduced.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
