Abstract

The utility model relates to an extruding machine provided with two stages of extruding mechanisms. A first-stage extruding mechanism is composed of a hydraulic cylinder 1, a piston 17, a front connecting plate 2, a connecting rod 3, an extruding mold 6 and a rear connecting plate 7. The hydraulic cylinder is matched with the piston in a sliding mode and is integrally connected with the front connecting plate through fit arrangement. The front connecting plate and the rear connecting plate are connected in series by the connecting rod, and both ends of the connecting rod are fastened by screw nuts. The extruding mold is installed on the rear connecting plate and is positioned on one side between the front connecting plate and the rear connecting plate. A second-stage extruding mechanism comprises a bearing plate composed of a rear connecting plate, a small connecting rod, a pressure plate and a bottom plate. A P type anchor which is integrally held and wrapped with a prestressing cable can be directly and integrally fastened with a single-hole anchor backing plate by the machine.

Description

Extruder

The utility model relates to a kind of extruder for preparing the squash type ground tackle of prestress anchorage cable.

Existing extruder has only the one-level pressing mechanism, and that extrudes bonds all-in-one-piece P type anchor with prestressed cable and can not directly be tightened to a community with the single hole anchor plate; Be assembled into community in order to bond all-in-one-piece P type anchor with the single hole anchor plate, need to increase the manufacturing procedure of single hole anchor plate, cost is improved with prestressed cable; Employing easily breaks away from transportation, carrying through the community that secondary assembling mode is combined into, and has arrived the job site and will ressemble, waste of manpower, time.

The purpose of this utility model is by improving the structure of extruder, provide a kind of can make extrude bond all-in-one-piece P type anchor with the direct fastening extruder that becomes community of single hole anchor plate with prestressed cable.

For reaching above-mentioned purpose, solution of the present utility model is: transform original extruder that has only the one-level extruding that constitutes with hydraulic cylinder, piston, stressed, combination die, bearing plate as have the two-stage pressing mechanism extruder, be to solve the release problems of second level pressing mechanism, the bearing plate of a monoblock is changed into by two blocks of steel plates with identical semicircle orifice form with the base plate that has U-lag being connected into the circular or hexagonal pressing plate of square.

First order pressing mechanism is made of hydraulic cylinder, piston, preceding connecting plate, connecting rod, extrusion die, back connecting plate, piston is slidingly matched with hydraulic cylinder, hydraulic cylinder is connected into one with preceding connecting plate by cooperating to install, connecting rod with preceding connecting plate connect with the back connecting plate, two ends are fastening with nut, extrusion die is installed on the connecting plate of back and in preceding connecting plate and a back side between the connecting plate; Connector bar one end be installed in the back connecting plate on, with the extrusion die heteropleural, the base plate that has U-lag is contained in the other end of connector bar, fastening with nut, the pressing plate of band semicircle orifice be installed on the base plate that has U-lag and between back connecting plate and base plate a side, constitute second level pressing mechanism.

Owing to adopt said structure, the extruder of the utility model has only the extruder of one-level pressing mechanism to compare with existing, has following advantage:

(1) can will bond all-in-one-piece P type anchor and directly be tightened to community with the single hole anchor plate with prestressed cable, avoid P type anchor in the community and the disengaging of single hole anchor plate in handling process, must carry out the situation that secondary assembles at the construction field (site), saved manpower, time;

(2) reduced the single hole anchor plate manufacturing procedure, simplify single hole anchor plate structure;

(3) steady quality, the outward appearance of the prestressed cable community of assurance manufacturing are clean and tidy.

Below in conjunction with drawings and Examples architectural feature of the present utility model is further described:

Embodiment:

A kind of extruder, as shown in Figure 1: described extruder has the two-stage pressing mechanism, with the steel plate of identical semicircle orifice circular or hexagonal pressing plate 12 of the square that is connected into (referring to Fig. 6) and the base plate 13 (referring to Fig. 5) that has a U-lag has been formed bearing plate by two.

First order pressing mechanism is made of hydraulic cylinder 1, piston 17, preceding connecting plate 2, connecting rod 3, extrusion die 6, back connecting plate 7, piston 17 is slidingly matched with hydraulic cylinder 1, hydraulic cylinder 1 is connected into one with preceding connecting plate 2 by cooperating to install, connecting rod 3 with preceding connecting plate 2 and back connecting plate 7 be together in series, two ends are fastening with nut 8, extrusion die 6 be installed on the connecting plate of back and preceding connecting plate with after a side between the connecting plate; Second level pressing mechanism comprises the bearing plate that back connecting plate 7, connector bar 9, pressing plate 12 and base plate 13 are formed, connector bar 9 one ends be installed in the back connecting plate 7 on, with extrusion die 6 heteropleurals, the base plate 13 that has U-lag is contained in the other end of connector bar 9, fastening with nut, and the pressing plate 12 of band semicircle orifice is installed on the base plate 13 that has U-lag and at back connecting plate 7 and have a side (referring to Fig. 2) between the base plate 13 of U-lag.

As a kind of conversion of the present utility model, a wiper block 10 (referring to Fig. 4) that has the isosceles trapezoid groove is installed also on pressing plate 12.

Among Fig. 1: the 4th, Extruding spring, the 5th, P shape anchor, the 11st, single hole anchor plate, the 15th, steel strand wires.

Using method is as follows: at first single hole anchor plate 11 is worn and hung on the steel strand wires 15, steel strand wires are successively by base plate 13, pressing plate 12, extrusion die 6, secondly be installed in Extruding spring 4, P shape anchor 5 on the steel strand wires 15, P shape anchor 5 puts and leans against extrusion die 6 prosopyle places, single hole anchor plate 11 centerings are placed on the wiper block 10 to set upright steel strand wires; After last piston 17 travelled forward P shape anchor 5 pushed through extrusion die 6 moulding, clamp-oning in the cooperation counterbore of single hole anchor plate 11 became a community.Open by two the pressing plates 12 of steel plate, community is taken out from extruder, finish whole extrusion processes being connected into identical semicircle orifice.
