Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

Please refer to fig. 1 to 3, which are schematic structural views of a multifunctional high-strength broken bolt tooth plate mold according to the present invention. A multifunctional high-strength broken bolt tooth plate die comprises a static tooth plate 10 and a movable tooth plate 20, wherein a buffering thread rolling structure 30 and an even thread rolling forming structure 40 which are horizontally connected are arranged on the static tooth plate 10 and the movable tooth plate 20. It is contemplated that the multi-functional high-strength broken bolt die further includes other functional components and specific structures, such as a fixed structure of the fixed die 10, a horizontal driving mechanism, a mounting structure, etc., which are well known to those skilled in the art, and thus, will not be described in detail herein.

The static tooth plate 10 and the movable tooth plate 20 are both in rectangular blocks. The static tooth plate 10 is fixed, the horizontal driving mechanism is connected with the movable tooth plate 20 and drives the movable tooth plate 20 and the static tooth plate 10 to move relatively, the static tooth plate 10 and the movable tooth plate 20 are staggered to force the crushing bolt to be clamped between the static tooth plate 10 and the movable tooth plate 20, and tooth rubbing is completed. The length of the static tooth plate 10 is smaller than that of the movable tooth plate 20, and the structure ensures that tooth rolling is more complete.

The buffering thread rolling structure 30 comprises a buffering plane 31, at least two first thread grooves 32 which are arranged on the buffering plane 31 and are parallel to each other at intervals, at least two first thread protrusions 33 which are arranged between the first thread grooves 32 and are parallel to each other, and at least two limiting notches 34 which are arranged on the first thread protrusions at intervals along the length direction of the first thread protrusions. The inner diameter of the first thread groove 32 is gradually reduced towards one side of the uniform thread forming structure 40 along the direction of the first thread groove 32, and the width of the first thread convex part 33 is gradually increased along the length direction of the first thread convex part 33. The thread pitch between the broken bolts is large, the broken bolts are fed from the buffer plane 31 through the change of the inner diameter of the first thread groove 32 and the width of the first thread convex part 32 in the buffer thread rolling structure 30, the broken bolts are slowly crushed and extruded to form holes on the surface of an optical axis of the original broken bolts, and the holes are expanded. In addition, the limiting notch 34 is used for buffering the thread rolling structure 30 to provide a fulcrum when the thread rolling structure rolls the outer wall of the optical axis of the broken bolt, so that the thread loosening phenomenon of the broken bolt is avoided, and the thread quality is improved. The limiting notch 34 is changed along with the width of the first thread convex part 33, when the width of the first thread convex part 31 is smaller, the length of the limiting notch 34 is shorter and the width is longer, and when the width of the first thread convex part 34 is smaller, the length of the limiting notch 34 is longer and the width is shorter.

Even thread rolling forming structure 40 includes that one sets up buffer plane 31 one side and be located the even plane 41 of upper end, one sets up ellipse screw thread forming plane 44 of even plane 41 lower extreme, at least two intervals set up even plane 41 and the insection groove two 42 that meet with insection groove 32, at least two settings are in insection convex part two 43 between insection groove two 42, at least two intervals set up on the ellipse screw thread forming plane 44 and respectively with insection groove three 45 that insection groove 32, insection groove two 42 meet, at least two settings are in insection convex part three 46 between insection groove three 45, and at least two edges insection groove three 45 length direction interval sets up the forming structure 47 in insection groove three 45. The inner diameter of the second thread groove 42 and the inner diameter of the third thread groove 45 are consistent towards the side far away from the uniform thread rolling forming structure 4740 along the direction of the second thread groove 42. The thread groove II 42 on the uniform plane 41 acts on the upper end of the crushing bolt, the shape of the thread formed by the thread groove I32 is further strengthened, and the thread at the upper end of the crushing bolt is kept in a uniform shape.

Similarly, the thread groove III 45 and the thread convex part on the oval thread forming plane 44 act on the upper end of the broken bolt, and the shape of the thread formed by the thread groove I32 is further strengthened, so that the thread at the lower end of the broken bolt is kept in a uniform shape. The three thread protrusions 46 are provided with arc-shaped convex surfaces 451 arranged along the length direction of the three thread protrusions 46, and due to the design of the arc-shaped convex surfaces 451 on the three thread protrusions 46, inward concave spiral grooves 51 are formed between threads at the lower end of the crushing bolt, so that the deformation amount of the lower end of the crushing bolt is increased, and incremental preparation is made for the elliptical threads 52. The formed spiral groove 51 can store sawdust and iron chips, the elliptical thread 52 has strong drilling capacity, and the broken bolt is drilled more smoothly.

The molding structure 47 includes a molding cavity 471 formed in the thread groove III 45, and a positioning groove 472 formed on the thread protrusion III 46 and communicating with the molding cavity 471. The inside diameter of the molding cavity 471 and the size of the positioning groove 472 both increase gradually along the length direction of the thread groove three 45, and the increment extruded by the arc convex surface 451 is extruded into the molding cavity 471, i.e. the arc corner is added on the thread edge to form the elliptical thread 52. The positioning groove 472 is used for positioning and guiding the cavity 471 in the forming process, so that the elliptical thread 52 is formed more completely.

The end of the static tooth plate 10 far away from the buffer area is a discharging end and is provided with a discharging inclined plane, and the discharging inclined plane is beneficial to separating from the die after the broken bolt thread rolling is finished.

In addition, the multifunctional high-strength broken bolt tooth plate die is also provided with a tail tooth rolling structure, and the structure is conventional in the field and is not described herein any further.

The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
