Abstract

The utility model relates to a device for machining metallic fiber materials, and the scheme is disclosed to solve the problems that the existing fiber material machining devices have a plurality of machining procedures, the route is long, the curve is numerous and the friction resistance is large during the continuous machining, and the machining quality of the fiber material is affected. In the utility model, a boosting fiber feeding roller of which the circumference surface is provided with a V-shaped groove is added before a back procedure, and the boosting fiber feeding roller is driven by power with adjustable rotary speed. A guide wheel is arranged in front of the boosting fiber feeding roller, the horizontal position of the guide wheel is variable, and thus, the guide wheel can adjust the working wrap angle of the boosting fiber feeding roller. Because the speed of the boosting fiber feeding roller is adjustable, the drawing tension of the fiber materials of the back procedure can be effectively reduced, the friction is reduced, the machining quality of the fiber materials is improved, and the productivity of the whole machine can be improved.

Description

The metal wire rod process equipment that has afterburning line sending roller

The utility model belongs to the metal wire rod process equipment, and it is specifically related to a kind of structure of new profile and wire process equipment.

In the production and processing of metal wire rod, the situation that often has multiple working procedure on every production line, to work continuously, for example, the elimination of internal stress, surface clear and upright, plating processing, passivation and washing etc.The driving power of wire rod mainly is the pulling force that wire rod is applied by power take-up equipment, because circuit is long, bending and friction point are many, causes in the operation drawing tension excessive and influence crudy easily, can also cause take-up pulley to drive difficult even wire rod is broken.

The purpose of this utility model is for solving the special this programme that proposes of aforesaid technical problem---have the wire rod process equipment of afterburning line sending roller, it is to set up one or more afterburning line sending rollers on demand at the inter process of the wire rod process equipment that uses at present, guarantees the crudy of wire rod so that the drawing tension of later process descends.

By as above design, the wire rod process equipment that has afterburning line sending roller that this programme provided includes the process equipment of actinobacillus wheel, guide roller, each operation, power-actuated take-up pulley, it is characterized in that before later process, setting up an afterburning line sending roller, it is by power drive, adjustable-speed, have on the periphery of its afterburning line sending roller and the part wire rod can be held the V-shaped groove that crouches wherein, have one in its place ahead for adjusting the guide wheel of afterburning line sending roller cornerite, the horizontal level of this guide wheel is adjustable.

In this programme, the angle of afterburning roller V-shaped groove is 5～120 °.

Adopt this programme can embody following superiority: 1. because of having reduced the drawing tension of the later process of afterburning line sending roller, so avoid a series of wire rod inherence that causes because of drawing tension is excessive and the problem of surface quality effectively; 2. can between multiple working procedure, establish a plurality of afterburning line sending rollers in case of necessity, make drawing tension balanced and reasonable on the whole production line; 3. afterburning line sending roller is that two sides by V-shaped groove contact with wire rod, and reliable transmission is to also not damaged of wire rod; 4. can reduce the bearing power of take-up pulley, reduce the wearing and tearing of equipment; 5. can boost productivity effectively; 6. its simple in structure, reliable low cost of manufacture is suitable for making in batches promoting the use of.

Fig. 1 is the structural representation that this programme has the wire rod process equipment of afterburning line sending roller.

Fig. 2 is that the structure of afterburning line sending roller and the section of processed wire rod contact schematic diagram.

Fig. 3 is the structural representation that has the wire rod process equipment of wire tension feedback closed loop adjusting.

The embodiment of existing accompanying drawings this programme.In wire rod process equipment commonly used, processed wire rod 2 through the process equipment 3,7 of guide roller 4 and multiple working procedure such as A, B, is got up by power-actuated take-up pulley rolling again after actinobacillus wheel 1 is drawn again.This programme is to set up an afterburning line sending roller 6 before later process, and its circumferential surface has the single or multiple V-shaped grooves that part wire rod appearance can be crouched wherein, and its angle α is 5～150 °.It is by power drive and adjustable-speed, and it should select harder metal material manufacturing for use, as cast steel.The afterburning roller of line sending is forward afterburning to wire rod, can alleviate the bearing power of the frictional resistance and the take-up pulley of process B equipment, be provided with an adjustment guide wheel 5 before the afterburning roller of line sending, the horizontal level of guide wheel is adjustable, to adjust the cornerite between the afterburning roller of wire rod and line sending, to satisfy technological requirement widely.

For the line sending speed that makes afterburning line sending roller and the speed of take-up pulley are complementary, afterburning line sending roller will be selected the harder power drive of speed characteristics for use, and promptly velocity variations is less during load variations, can select for use the buncher of tape speed feedback and technology phase time to answer.The take-up pulley of back then can adopt softer torque motor of characteristic or frictional drive, and its duty is adjusted to can provide certain force of strain and don't can overspeed for afterburning line sending roller.Generally speaking can be by manually regulating according to the tensioning degree of range estimation wire rod.If the line sending speed of afterburning line sending roller is greater than the linear velocity of take-up pulley, wire rod on the V-shaped groove has just lost the drawing tension to afterburning line sending roller, wire rod is sent power to because of self stress just can get loose to lose with the V-shaped groove face, can not cause the phenomenon of heap line, and this just makes artificial the adjustment greatly simplify.

In the time on same lines, must adopting the afterburning roller of multiple tracks line sending, should be by process sequence, from the unwrapping wire to the take-up, the speed characteristics of its power should be step by step by hard to soft, as reducing the negative velocity feedback amount of buncher step by step.

The technology strict to some wire tension also can adopt the closed-loop adjustment of tension feedback.As shown in Figure 3, increase by one in the back of the afterburning roller of line sending and produce the slide roller 9 of change in location according to wire tension, and drive the sliding contact C of a potentiometer 10 indirectly by it, the current potential that C order is exported corresponding with the position of slide roller.Slide roller is pulled upwardly when the drawing tension of wire rod surpasses certain normal value for a certain reason, the C point output potential of potentiometer changes accordingly, afterburning line sending roller speedup or take-up pulley are slowed down, this moment, the drawing tension of wire rod reduced, and was in balance and stable state until slide roller.The counterweight that changes movable pulley then can change the tension state of wire rod.

The model machine of this programme is through experiment operation proof: it has stable and reliable for performance, line tree crudy greatly takes on a new look, reduces take-up power, minimizing equipment attrition, improved productivity ratio, is subjected to user's favorable comment deeply.
