Problems solved by technology
In the practice of the production site, it is found that the eccentric rolling control of the eccentric shaft is used to adjust the dimensional accuracy of the steel wire head. Another reason is that the mechanism of the device crosses and easily interferes with each other, which will cause the concentricity circle of the three helical tooth roller wire wheels during the installation process. The precision quality of the

[0041] Instructions attached figure 1The right side of the main view begins to elaborate: the synchronous pulley internal gear (40) can be used as the inner lining ring of the steel wire rolling bearing, and it can be used as the synchronous torque power output part when rolling the steel wire head, and the three synchronous gears (42) ] are respectively installed in the three holes of the evenly divided synchronous pulley internal gear (40), and then the protruding trapezoids on the three cross sliders (41) are respectively installed into the concave trapezoidal grooves on the synchronous gear (42) , combined into a synchronous gear assembly capable of outputting synchronous power. Steel wire bearing (34) is to be main rolling member by steel ball, and steel ball is set off by four steel wire circles around, it and steel wire bearing shell seat (35), steel wire bearing lock nut (36) and on the synchronous pulley internal gear (40) Groove liner ring belongs to the combination...

The invention discloses a reinforcing wire head axial rolling machine device. Three combination parts composed of roller wire wheels are evenly distributed in a triangular frame cavity. The reinforcing wire head axial rolling machine device is characterized in that the end portions of the roller wire wheels of each combination part protrude to be connected with cross-shaped sliding block grooves in a synchronous transmission gear combination part in a potential and inserted manner to form a synchronous gear transmission mechanism. The three roller wire wheel combination parts can rotate around the rotation center of a reinforcing rib all the time till a reinforcing wire head is manufactured, and the size of the reinforcing wire head can be adjusted only by simply rotating a fine adjustment sleeve. Four tool combination parts are evenly distributed in a rectangular frame cavity and can rotate around the rotation center of the reinforcing rib all the time. Three process steps of feeding (chamfering), returning (rounding) and retracting of the tool combination parts are completed instantly and intermittently by a pair of electromagnet brakes which are controlled by PLC instruction electric signals when a positioning inner gear rotary disc runs, and the size, the angle and the depth of the reinforcing rib can be adjusted only by rotating a manual inner gear drive plate with scale values during metal cutting. In addition, it should be known that when a right reinforcing wire head is rolled, a left roller wire wheel machine head must be selected to run anticlockwise.
Description
technical field [0001] A kind of professional equipment invented and designed for the steel bar straight thread thread head connection joint in the mechanical connection of steel bars in the construction industry. It is specifically suitable for rolling the steel bar straight thread thread head with a nominal diameter of 16mm-50mm, and can also roll the same type of round steel The pitch range of steel bar straight thread head and rolled steel wire head: P2.00, P2.50.P3.00, P3.50, P4.00. Also capable of rolling full length rebar straight threaded screws. Background technique [0002] As far as the current situation is concerned, the construction industry in my country basically adopts "reinforcement mechanical connection", and now the steel bar straight thread thread head connection joint is widely used. The applicant has applied for two invention patents on September 25, 2006. The name of the invention patent is: helical gear rolling steel wire head device. The case has be...
