Abstract

A V-shaped rib rolling and forming machine comprises a roller drive device, a roller frame, an upper roller and lower roller. The upper roller and lower roller have a V-shaped groove. The two roller roll at least twice when in molding. Height of the V-shaped groove increases by degrees with the times, and the peaked top of which has the conversed angle with the same bending rate. The roller drive device consists of a mechanical infinite speed change reducer, a large chain wheel which is rotated with the chain, a guide device which is arranged at the feeding inlet and provided with two rows of the positioning pins, a rotating gear which is coaxial with the roller, a transitional gear which is positioned between the rotating gears and transmitted by the large gear and an adjusting bolt. The machine is continuously formed, with small error and high producing efficiency. Space between the upper and the lower roller can be adjusted.

V-arrangement rib roller head machine

The utility model relates to a kind of V-arrangement rib make-up machine that is used for the band material expanded metal lath of concrete works.

In concrete works, often use a kind of band material---expanded metal lath with the V-arrangement rib, this band V-arrangement rib steel expanded metals also is one of vitals of DIPY construction formwork mesh; Present manufacturing technology is to use V-arrangement rib mould on four-column hydraulic press, suppresses the required V-arrangement rib of band V-arrangement rib steel expanded metals, is simply described as follows:

Fig. 1 is the formed in mould schematic diagram of V-arrangement rib of prior art.

Wherein: 1. suppress die 2. alignment pins 3. moulding web plates 4. convex mould bases 5. punch 6. elastomer block 7. flanging pieces.

With alignment pin after the punching press and put into compacting die (1) by the steel plate net (3) that certain-length is cut out (2) between, by the position, the left and right sides of alignment pin (2) assurance moulding web plate, punch (5) is fixed on convex mould base (4) On, convex mould base (4) is fixed on the slider of hydraulic press bottom surface, when hydraulic machine slide block down, by punch (5) Finish the V work of pressing. The effect of flanging piece (7) is when moulding, and the part of not moulding is applied a pressure, Keep the smooth of moulding, the compression strain of elastomer block (6) is recovered when returning simultaneously, with the worker after the moulding Part pushes away down from punch (5).

The deficiencies in the prior art show: the preceding need of the compacting band material that punching press is good is cut off, coarse positioning, and production efficiency is low, and the workpiece location is inaccurate, and forming errors is big.

The purpose of this utility model provides a kind of V-arrangement rib roller head machine, and continuous immediately roll forming forming V-shape rib reduces forming errors after automatic stamping is finished, and enhances productivity.

The purpose of this utility model is by with continuous band material to be formed, directly sends into number row and synchronously rotates, has the design realization of rolling roll forming between the V roller up and down that V-shaped groove mouth and notch height increase progressively continuously.

V-arrangement rib roller head machine of the present utility model comprises frame, down roller, roll driving apparatus; Described frame comprises support and is fixed on roller bracket on the support; Be equipped with the V-shaped groove mouth on the described down roller and be at least twice and roll the V roller up and down, they are respectively once to roll the V top roll, once roll that V lower roll and secondary roll the V top roll, secondary rolls the V lower roll, the height of the V-shaped groove mouth of roller increases progressively with number of times, and all curvature of rolling the pinnacle place chamfering of V-shaped groove mouth of V roller and chamfering up and down are identical; Described roll driving apparatus is by the mechanical stepless speed change decelerator that is fixed in the support, and chain drive between the mechanical stepless speed change decelerator, which is provided with the hinge wheel of in-line gears, be positioned at the guider that band is expected import department and is provided with and becomes with the material longitudinal axis axisymmetric two registration pins, the identical transmitting gear coaxial with roller, identical transition gear between transmitting gear and adjust the adjustment screw roll V roller spacing up and down and constitute is with the in-line gears transmission of the contiguous transition gear of hinge wheel by hinge wheel.

As the further improvement of V-arrangement rib roller head machine of the present utility model, the described V roller that rolls up and down is to roll the V roller up and down five times, is respectively to roll the V top roll and roll the V lower roll one to five time for one to five time.

V-arrangement rib roller head machine of the present utility model, described band material is expanded metal lath or steel wire.

V-arrangement rib roller head machine of the present utility model, advantage is: at the band material, after the continuous punching production as expanded metal lath, the band material is via guider continuously, directly the V-shaped groove open height by number row synchronous working increases progressively rolls roll forming continuously between the V roller up and down, forming errors is little, the production efficiency height; V-arrangement ribbed roller wheel adopts mechanical type gear Synchronous Transmission, and rotating speed is stepless adjustable; Rolling the gap of V roller roller up and down also can adjust flexibly.

V-arrangement rib roller head machine of the present utility model is suitable for the V-arrangement rib moulding of metal lath, is particularly suitable for the V-arrangement rib moulding of expanded metal lath.

Below in conjunction with embodiment V-arrangement rib roller head machine of the present utility model is described further.
