DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1~Figure 5As shown, this embodiment proposes an anchor rod reducing machine for anchor rod production, including a base 1, one end of the top of the base 1 is provided with a guide mechanism 2 for guiding the anchor rod, the other end of the top of the base 1 is fixedly connected with a mounting frame 3, the inner side of the mounting frame 3 is provided with an extrusion mechanism 4, the extrusion mechanism 4 includes two cylinders 41 symmetrically distributed along the center of the mounting frame 3, the output ends of the two cylinders 41 are fixedly connected with movable seats 42, the bottoms of the two movable seats 42 are rotatably connected with rotating shafts 43, the middle parts of the two rotating shafts 43 are fixedly connected with extrusion wheels 44 that contact with the anchor rod, the bottoms of the two rotating shafts 43 are rotatably connected with movable frames 45, the bottoms of the two movable frames 45 are slidably connected with the bottom wall of the inner side of the mounting frame 3, and the bottom end of the inner side of the mounting frame 3 is provided with a driving component 48 that drives the two rotating shafts 43 to rotate synchronously towards each other.

[0024] By controlling the two cylinders 41 to make the two movable seats 42 move towards each other, the two extrusion wheels 44 will come into contact with the anchor rod and squeeze it, so that anchor rods with different diameters can be processed. Then, the two rotating shafts 43 are driven to rotate towards each other synchronously through the driving assembly 48, so that the two extrusion wheels 44 will rotate towards each other synchronously and squeeze the same position of the anchor rod, thereby reducing the diameter of the anchor rod at the squeezed position. Since the two extrusion wheels 44 always keep rotating synchronously, the problem of misalignment of the extrusion positions of the two extrusion wheels 44 and the reduction of the diameter quality of the anchor rod can be avoided.

[0025] Furthermore, the top of the inner side of the mounting frame 3 is fixedly connected with a guide rail 1 46, the bottom of the inner side of the mounting frame 3 is fixedly connected with a guide rail 2 47 arranged parallel to the guide rail 1 46, the two movable seats 42 are slidably connected with the guide rail 1 46, and the two movable frames 45 are slidably connected with the guide rail 2 47. The movable seat 42 and the movable frame 45 are guided by the guide rail 1 46 and the guide rail 2 47 respectively, so that the movable seat 42 and the movable frame 45 can move smoothly.

[0026] Furthermore, the driving assembly 48 includes a spline 481, which is rotatably connected to the bottom end of the inner side of the mounting frame 3. A motor 482 is fixedly installed on the outer side of the mounting frame 3, and the output shaft of the motor 482 is fixedly connected to the spline 481. The inner sides of the two mounting frames 3 are rotatably connected with spline sleeves 483, which are sleeved on the spline 481 and slidingly connected to the spline 481. One end of the two spline sleeves 483 is provided with a transmission member 484 for driving the corresponding rotating shaft 43 to rotate. The transmission member 484 includes a bevel gear 1 4841, which is fixedly connected to one end of the corresponding spline sleeve 483. A bevel gear 2 4842 is fixedly connected to the bottom of the rotating shaft 43, and the bevel gear 1 4841 is meshed with the corresponding bevel gear 2 4842. The bevel gears 1 4841 on the two spline sleeves 483 are symmetrically distributed along the center line of the mounting frame 3, and the rotation directions of the two bevel gears 1 4841 are opposite.

[0027] By starting the motor 482 to drive the spline 481 to rotate, the two spline sleeves 483 can rotate synchronously. Since the spline sleeve 483 is slidably connected to the spline 481, the spline sleeve 483 always keeps synchronous rotation with the spline 481 during the translation of the movable frame 45. This ensures that the translation of the movable frame 45 will not affect the normal rotation of the spline sleeve 483 when reducing the diameter of anchor rods of different diameters, thereby causing the corresponding bevel gear 1 4841 to rotate. Since the two bevel gears 1 4841 are symmetrically distributed along the center line of the mounting frame 3, the rotation directions of the two bevel gears 2 4842 are opposite, which can make the two rotating shafts 43 rotate synchronously towards each other, which makes the two extrusion wheels 44 rotate synchronously towards each other and squeeze the same position of the anchor rod, thereby reducing the diameter of the extruded position of the anchor rod.

[0028] Furthermore, the guide mechanism 2 includes a fixed frame 21, which is fixedly connected to the top of the base 1, and a rotating disk 22 is rotatably connected to one side of the fixed frame 21, and a plurality of guide molds 23 distributed at equal angles along the rotating disk 22 are fixedly connected to the outer edge of the rotating disk 22, and the inner diameters of the plurality of guide molds 23 are different, and the inner diameters are distributed from bottom to top along the circumference of the rotating disk 22, and a hand crank 24 coaxially fixed to the rotating disk 22 is rotatably connected to the other side of the fixed frame 21, and a guide wheel 25 is rotatably connected to the top of the fixed frame 21, and the center of any guide mold 23 can be in the same plane with the axis of the guide wheel 25 through the rotation of the rotating disk 22. Anchor rods of different diameters can be guided by guide molds 23 with different inner diameters, and the rotating disk 22 can be rotated by rotating the hand crank 24, so that the guide molds 23 with different inner diameters can be switched to the corresponding guiding position to guide the anchor rod.

[0029] Working principle: First, the anchor rod is guided between the two extrusion wheels 44 through the guide die 23, and then the two cylinders 41 are controlled to make the two movable seats 42 move toward each other, which makes the two extrusion wheels 44 contact and squeeze the anchor rod, and then the motor 482 is started to drive the spline 481 to rotate, which makes the two spline sleeves 483 rotate synchronously. Since the spline sleeve 483 is slidingly connected with the spline 481, the spline sleeve 483 of the movable frame 45 always keeps synchronous rotation with the spline 481 during the translation process, which makes the translation of the movable frame 45 when reducing the diameter of anchor rods of different diameters will not affect the normal rotation of the spline sleeve 483, so that the corresponding bevel gear 1 4841 rotates, and since the two bevel gears 1 4841 are symmetrically distributed along the center line of the mounting frame 3, the rotation directions of the two bevel gears 2 4842 are opposite, which can make the two rotating shafts 43 rotate synchronously towards each other, which makes the two extrusion wheels 44 rotate synchronously towards each other and squeeze the same position of the anchor rod, thereby reducing the diameter of the anchor rod at the squeezed position.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
