DETAILED DESCRIPTION

[0023] The utility model will be further described in detail in combination with the drawings.

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0025] Please refer to Figures 1-4 , the utility model provides technical scheme: a kind of thread forming with thread rolling plate, the thread rolling plate includes static plate 1 and dynamic plate, static plate 1 and dynamic plate are symmetrically arranged, the static plate 1 or the dynamic plate is sequentially provided with inlet area 2, transition area 3, thread forming area 4 and discharge area 5 from left to right, first thread 6 is uniformly distributed on the inlet area 2, the top of first thread 6 is triangle, second thread 7 is uniformly distributed on the thread forming area 4, and the top of second thread 7 is trapezoidal, transition thread 12 for connecting first thread 6 and second thread 7 is uniformly distributed on the transition area 3, and the static plate 1 or the dynamic plate is slidably connected with detachable plate 8, and thread forming area 4 and discharge area 5 are located on detachable plate 8, and detachable plate 8 is located on the side of transition area 3 away from inlet area 2.

[0026] Among them, static plate 1 or the dynamic plate is provided with groove 9, for the installation of detachable plate 8.

[0027] Groove 9 is internally provided with T-shaped sliding groove 10, and T-shaped connecting rod 11 is integrally formed on the end of detachable plate 8 facing groove 9.

[0028] In turn, detachable plate 8 can be pushed out of the thread rolling plate up and down, since the workpiece advancing direction is located in the length direction of the thread rolling plate, the direction of T-shaped sliding groove 10 is perpendicular to the length direction of the thread rolling plate,

[0029] In the embodiment, the top angle of first thread 6 of the inlet area 2 is inclined and curved outward, and the internal angle of the triangle at the top of first thread 6 is 60°. Under the premise of ensuring accuracy, the inclined and curved first thread 6 can avoid the slipping of the lead screw during the thread rolling process, and improve the stability of thread rolling.

[0030] Preferably, the surface of the inlet area is sandblasted, which can increase the surface roughness of the inlet area, increase the friction, and further reduce the risk of lead screw slipping.

[0031] Each of the second threads 7 corresponds to the first thread 6 one by one, and the second thread 7 is on the extension line of the first thread 6.

[0032] The inclined surface 13 is arranged at the bottom of the detachable plate 8 and is away from the thread forming area 4, facilitating discharging after the thread rolling of the screw rod is completed. Preferably, the inclined surface 13 gradually decreases from top to bottom along the width direction of the detachable plate 8, so that the heights of the upper and lower sides of the inclined surface are different, for example, the length of the upper side of the inclined surface 13 is a, and the length of the lower side is b, wherein b is greater than a, that is, the depth of the lower side of the inclined surface cutting into the detachable plate 8 is greater, and the screw rod gradually loses the extrusion of the moving plate before completely sliding out of the discharging area 3, avoiding the deflection and sliding of the screw rod, and ensuring stable discharging.

[0033] The feeding area and the transition area 3 are integrally arranged, and the 60° triangular thread is adopted to preliminarily extrude the thread into a triangular shape, which prevents the screw rod from slipping and reduces the occurrence of material folding; the specification of the 60° triangular thread changes according to the change of the specification of the trapezoidal thread, and the volumes of the two are basically the same.

[0034] The thread forming area 4 and the discharge port occupy more than 1 / 2 of the whole thread rolling plate, and the overall size is consistent with the target size of the screw rod, so that the product precision is ensured by adopting a one-time forming process; in the embodiment, the thread forming area 4 is connected to the static plate 1 or the moving plate in a sliding manner, and can also be connected to the static plate 1 or the moving plate by an internal thread, a positioning pin or the like. Since the product precision is extremely high, the service life of the thread forming area 4 is relatively low, and the production cost can be reduced and the production precision of the thread rolling plate can be improved by the form of the insert block, so as to ensure the product size; the thread forming of the part is completed after the transverse extrusion of the static plate 1 and the moving plate.

[0035] The working principle of the utility model is as follows: the application is used for the machining and forming of a screw rod or a worm rod, in the machining, the static plate 1 and the moving plate are fixed by an external device, the screw rod or the worm rod is made based on the thread rolling forming principle, the screw rod or the worm rod enters along the feeding area, sequentially passes through the first triangular thread 6 on the feeding area 2, the second trapezoidal thread 7 on the transition area 3, then passes through the thread forming area 4, and finally is guided out along the discharging area 5.
