Description

There is the forming machine ultrasonic cutter device cutting defencive function

Technical field

This utility model relates to forming machine ultrasonic cutter device, and a kind of have the forming machine ultrasonic cutter device cutting defencive function, belongs to tire building processing technique field.

Background technology

The working contents of tyre building machine is that the rubber for tire parts of each rolling are automatically led out fixed length and cut, and becomes green tyres according to a definite sequence assembly.Automatically the dependence ultrasonic cutter that cuts of rubber components is carried out, and during work, ultrasonic cutter slowly moves along guide rail under drive mechanism drives, and cuts rubber components.The operation principle of ultrasound wave cutting is to produce mechanical vibration by conversion high-frequency electrical energy, and sizing material is cut by the mode utilizing edge of a knife vibrational energy activation rubber molecule and to open strand, and the edge of a knife does not directly contact with sizing material.But in process of production, being easily mixed into metal impurities in sizing material in the preceding working procedure that sizing material produces, when impurity is placed exactly in and cuts on route, some solid impurity cannot be cut by ultrasonic cutter by mechanical vibration.But owing to ultrasonic cutter can drive by driven-mechanism by force, the edge of a knife of ultrasonic cutter thus can be made to bump against extruding with impurity, cause ultrasonic cutter fault to damage, need to change ultrasonic cutter, and ultrasonic cutter somewhat expensive, about 30,000 yuan/, cause production cost too high.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art; a kind of forming machine ultrasonic cutter device having and cutting defencive function is provided; the design of its structure is simple; improvement cost is cheap; use reliable and secure; may insure that and can stop at once when ultrasonic cutter is just cut to metal impurities moving, it is to avoid cut-off knife damage by force.

The technical scheme provided according to this utility model: there is the forming machine ultrasonic cutter device cutting defencive function, including ultrasonic cutter, described ultrasonic cutter is arranged on cutter rack, cutter rack is slidedly assemblied on guide rail, cutter rack can move along guide rail under drive mechanism drives, it is characterized in that: described drive mechanism includes motor, torque limiter, driving pulley, driven pulley and Timing Belt, described torque limiter is arranged on the output shaft of motor, described driving pulley is arranged on torque limiter, driving pulley is positioned at the side of guide rail one end, described driven pulley is arranged on the side of the guide rail other end, described Timing Belt is enclosed within driving pulley and driven pulley, described cutter rack is connected on Timing Belt.

This utility model compared with prior art, has the advantage that

The design of this utility model structure is simple, improvement cost is cheap, by adding torque limiter between motor output shaft and driving pulley, the torque range of torque limiter can be finely tuned during use, make it mate ultrasonic cutter and normally cut the mobile driving force needed for sizing material, when the opposite direction having unnecessary power to put on the cut-off knife direction of motion, torque limiter i.e. transships, use reliable and secure, may insure that and can stop at once when ultrasonic cutter is just cut to metal impurities moving, it is to avoid cut-off knife damage by force.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model embodiment.

Detailed description of the invention

Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.

As shown in Figure 1: having in embodiment cuts forming machine ultrasonic cutter 1 device of defencive function and be mainly made up of etc. ultrasonic cutter 1, cutter rack 2, guide rail 3, motor 5, torque limiter 6, driving pulley 7, driven pulley 8 and Timing Belt 9 and form.

As it is shown in figure 1, described ultrasonic cutter 1 is arranged on cutter rack 2, on guides 3, cutter rack 2 can move under drive mechanism drives cutter rack 2 slidable fit along guide rail 3；Described drive mechanism is mainly made up of motor 5, torque limiter 6, driving pulley 7, driven pulley 8 and Timing Belt 9, described torque limiter 6 is arranged on the output shaft of motor 5, described driving pulley 7 is arranged on torque limiter 6, driving pulley 7 is positioned at the side of guide rail 3 one end, described driven pulley 8 is arranged on the side of guide rail 3 other end, described Timing Belt 9 is enclosed within driving pulley 7 and driven pulley 8, and described cutter rack 2 is connected on Timing Belt 9.

Time specifically used, the mobile driving force needed for first normally cutting sizing material 4 according to ultrasonic cutter 1 finely tunes the torque range of torque limiter 6.Then motor 5 drives torque limiter 6 and driving pulley 7 to rotate, and driving pulley 7 and driven pulley 8 coordinate, and orders about Timing Belt 9 and turns round, and drives cutter rack 2 and ultrasonic cutter 1 slowly to move along guide rail 3, cut sizing material 4 when Timing Belt 9 turns round.When cut have impurity on route time; ultrasonic cutter 1 produces resistance when just contacting with impurity; just have unnecessary power and put on the opposite direction of the cut-off knife direction of motion; torque limiter 6 i.e. transships to produce and separates, and motor 5 output shaft dallies, and Timing Belt 9 no longer carries out action; now ultrasonic cutter 1 stops moving on; do not continue to the impurity that cannot cut interior with sizing material 4 by force and carry out bumping against extruding, thus be prevented effectively from ultrasonic cutter 1 fault and damage, cut-off knife is played a protective role.
