Abstract
Provided is a reinforcing bar thread rolling machine. A thread rolling die is disposed between a main machine head body and a knife body holder via a camshaft, which is connected with the main machine head body and the knife body holder via reversible buckle guide sleeves. One side of the camshaft relative to the main machine head body is engaged with an internal gear ring via a shaft-mounted gear, wherein the internal gear ring is simultaneously engaged with an adjusting gear. An included angle between the reversible buckle guide sleeve axis and the machine head axis is identical to a helix angle, and the reversible buckle guide sleeves allow 180-degree direction adjustment. Rib stripping knives are clamped via clamping bolts on machine head knife blocks, which are radially arranged on a side surface of the knife body holder via a T-shaped groove structure and are capably of sliding along the T-shaped groove via springs and top threads at two ends. The processing of positive and negative threads can be realized without adding extra components on the machine head, and the machine head can replace a negative thread machine head, effectively reducing the machine cost. The rib stripping knives enable to flexibly adjust the processing size via the machine head knife blocks and are suitable for rib stripping processing of reinforcing bars of different sizes. Meanwhile, the reinforcing bar thread rolling machine is convenient to dismount and allows regrinding and reuse of the rib stripping knives.
Description
Technical field
The utility model relates to a kind of screw-rolling machine, particularly a kind ofly is used to connect the thread roller of steel bar of building spiral.
Background technology
At present, when connecting the building spiral, because the reinforcing wire head needs positive silk to be connected with anti-silk, every machine of thread roller of steel bar therefore commonly used all has 2 heads, 1 of positive silk, 1 of anti-silk, positive silk anti-silk each stature, many costs of accessory cost height like this.In addition, the rib peeling knife sheet of traditional thread roller of steel bar cannot grind repeatedly, and having gone bad just needs to change blade, and is so not only loaded down with trivial details but also increased cost.
The utility model content
The purpose of this utility model provides the anti-silk of a kind of positive silk only with a head just can all process and rib peeling knife can use repeatedly thread roller of steel bar.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of thread roller of steel bar is equipped with cylindrical die roll and rib peeling knife on the head that joins with the reductor terminal pad, and it is characterized in that: described cylindrical die roll is installed between the crosshead body and cutter hub frame of head by camshaft; Described camshaft joins by positive left-hand thread guide pin bushing and described crosshead body and cutter hub frame respectively, and in gear and inner gear ring engagement that a relative side of crosshead body is adorned by axle, described inner gear ring is meshed with adjusting gear simultaneously; Described positive left-hand thread guide pin bushing axis is identical with the spiral shell lift angle with the angle of head axis, by bolting, and can carry out 180 degree transposing directions.
Further, described rib peeling knife is held on the head cutter piece by fishbolt, and described head cutter piece is radial by T-shape groove structure and is installed on the described cutter hub frame side, by the spring and the jackscrew at two ends, can slide along the T-shape groove.
Preferably, the quantity of described camshaft, gear, cylindrical die roll is three, is uniformly distributed along the circumference.
Preferably, the quantity of described rib peeling knife, head cutter piece, spring and jackscrew is four, is uniformly distributed along the circumference.
The beneficial effects of the utility model are, adopt positive left-hand thread guide pin bushing to make cylindrical die roll produce row spiral shell lift angle, 180 degree transposing directions by positive left-hand thread guide pin bushing, can realize the switching of positive and negative spiral shell lift angle, on a head, need not increase the processing that other parts can be realized positive and negative screw thread, alternative anti-silk head effectively reduces machine cost; Make the inner gear ring rotating certain angle by adjusting gear,, can adjust the distance between axles of cylindrical die roll, can realize that the reinforcing bar of different-diameter carries out roll extrusion through the camshaft conversion; Rib peeling knife can be adjusted processing dimension flexibly by head cutter piece, and the reinforcing bar that is fit to different size is shelled rib processing, and is simultaneously for convenience detach, and rib peeling knife is carried out regrinding, can use repeatedly.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is thread roller of steel bar handpiece structure figure one described in the utility model;
Fig. 2 is thread roller of steel bar handpiece structure figure two described in the utility model;
Fig. 3 is a thread roller of steel bar handpiece structure schematic diagram described in the utility model.
Among the figure:
1, crosshead body; 2, head overcoat; 3, cutter hub frame; 4, head cutter piece; 5, rib peeling knife; 6, clamp stud; 7, jackscrew; 8, hole; 9, positive left-hand thread guide pin bushing; 10, cylindrical die roll; 11, camshaft; 12, gear; 13, jump ring; 14, inner gear ring; 15, adjusting gear; 16, spring.
The specific embodiment
As Figure 1-3, provided this reality novel described thread roller of steel bar handpiece structure and schematic diagram have been arranged, it joins by bolt and reductor terminal pad, crosshead body 1, head overcoat 2 and cutter hub frame 3 are inter-connected via a bolt joint and are one, cylindrical die roll 10 is installed between the crosshead body 1 and cutter hub frame 3 of head by camshaft 11, camshaft 11 is an eccentric shaft in this section, by its rotation, can change the distance in the distance of shaft centers head axle center of cylindrical die roll 10.
Described camshaft 11 joins with described crosshead body 1 and cutter hub frame 3 by positive left-hand thread guide pin bushing 9 respectively, the gear of adorning by axle in a relative side of crosshead body 1 12 meshes with inner gear ring 14, adopt jump ring 13 to carry out spacing, described inner gear ring 14 is meshed with adjusting gear 15 simultaneously, the quantity of camshaft 11, gear 12, cylindrical die roll 10 is three, is uniformly distributed along the circumference; Gear 15 is adjusted in rotation, can drive inner gear ring 14 and rotate, and rotates thereby drive three gears 12, further makes the distance between axles of three cylindrical die rolls produce and changes, locked after, can adapt to the reinforcing bar of processing different specification size.
Described positive left-hand thread guide pin bushing 9 axis are identical with the spiral shell lift angle with the angle of head axis, pass through bolting, as angle among the figure is 2 degree, can be used to process the reinforcing bar that the spiral shell lift angle is 2 degree, after carrying out 180 degree transposing directions, its angle is 2 degree of bearing, and changes the direction of rotation of head simultaneously, can process anti-silk screw thread, realize anti-silk processing.
