Abstract

The utility model discloses a metal-wire hydraulic packaging machine belonging to an on-line packaging device of a wire-rolling production line. The device adopts a hydraulic cylinder arranged on a line of centers of two pressed rotating discs as a drive source so as to directly drive the movable rotating discs to press a wire coil; and the wire coil is pressed to be compact, and the resilience amount is small after pressure is released. The device adopts a miniature hydraulic shear to cut off a seizing line; the miniature hydraulic shear is high in cutting speed and reliable in running, and is suitable for continuous operation. The device is flexile to operate, is reliable to run, and is particularly suitable for the modern high-line rolling production line.

Description

A kind of metal wire rod hydraulic press-packing

Technical field:

The utility model belongs to a kind of baling equipment of metal wire rod rolling line, especially belongs to a kind of bundled packing apparatus of dish circle of carbon steel soft or hard line continuous rolling production line, and it is specially adapted to the high-speed and continuous Rolling Production of wire rod.

Background technology:

The coil of wire hold-down mechanism of the baling press that existing wire rod rolling production line uses, most screw thread pair mechanisms that adopt; The screw rod that promptly adopts motor-reductor to drive in the screw thread pair rotates, and makes the nut that is fixed in the movable disk seat drive movable disk seat moving linearly, compresses the coil of wire (seeing accompanying drawing 3) thereby drive movable disk.Because when the screw thread pair design feature has determined to arrange in the space, nut-screw mechanism can only be arranged in the interior bottom of support of baling press, this position that compresses power that just causes it to produce is lower than coil of wire center line (mostly more than 500mm) forever, and this is to cause one of principal element that compresses weak effect; Simultaneously since the many faying faces of parts to accumulate the gap big more, cause the strain of entire mechanism big, rigidity is poor, therefore, the big and springback capacity of the final lengths springback capacity of the coil of wire that packing is good after the release changes greatly, entire length tolerance often exceed standard (seeing accompanying drawing 3,4).

Existing baling press mostly uses miniature electric resin wheel cutting machine to cut off the bundle silk of tying up the coil of wire.In continuous production operation, spark splashes, and grinding wheel is changed frequent, and miniature electric resin wheel cutting machine is because of frequent damage of unsuitable long-time frequent starting.

Summary of the invention:

The coil of wire that the purpose of this utility model provides after a kind of packing is closely knit, and final lengths is stable, and length tolerance meets the requirement of national standard defined, can adapt to the baling press of long-time continuous operation.

At first, the utility model adopts the alternative screw thread pair driving of hydraulic system movable disk seat drive movable disk to do rectilinear motion and compresses the coil of wire; This device will compress on the line of centres that main hydraulic cylinder is arranged in fixedly rotating disk and movable disk, and this line of centres and the coil of wire compress central lines, make thrust can be used to compress the coil of wire to greatest extent; And the big portion of springback capacity after the ubiquitous coil of wire release that causes because of hold-down mechanism accumulation gap and strain of existing baling press fundamentally the eliminated problem that exceeds standard.

Secondly, the utility model adopts micro hydraulic to shear and pricks silk, and it is reliable that this micro hydraulic is cut the fast operation of the big speed of the little shearing force of volume, can adapt to the long-time continuous operation.Owing to do not produce the dust spark, can save metal and improve working conditions.

Technical scheme:

The technical scheme that its technical problem that solves the utility model adopts is: 1, this device adopts hydraulic system to replace screw thread pair to drive the movable disk seat, directly hydraulic cylinder is arranged in movable disk one fixedly on the line of centres of rotating disk, hydraulic stem and movable disk seat are hinged.When the loose coil of wire lift up between two rotating disks and an end against fixing rotating disk behind the position that falls on the cylinder, the primer fluid pressing system, piston rod (indirectly) promotes the movable disk compressing coil of wire and squeezes forward, start cylinder and fixedly rotating disk drive coil of wire rotation simultaneously, thereby realize technology purpose the coil of wire " jam-packed " while rotating.Around here, this device can be adjusted the traffic direction and the speed of movable disk neatly according to actual conditions.The movable parts of the hold-down mechanism that this device adopted are few, and the motion contact-making surface is few, and the gap accumulation is few, and rigidity is big, and thrust is big, and therefore, the springback capacity of the coil of wire is very little after the release.2, this device adopts high-pressure mini Driven by Hydraulic Cylinder cold shear to cut off the bundle silk of tying up the coil of wire, owing to adopt high-pressure hydraulic, the shear rate that micro hydraulic is cut is fast, and is reliable, and no dust spark can adapt to the long-time continuous operation.

Beneficial effect;

In high-speed wire rolling is produced, the utility model adopts the technical scheme of " make movable disk roll up center line along the line by hydraulic stem promotion movable disk seat and compress the coil of wire ", the precise control of movable disk flexible operation, effectively thrust is powerful, therefore, the finished product coil of wire packing height that packing is come out, springback capacity is little after the release, the final lengths of the coil of wire is precise and stable, complies with the national standard requirements fully.

This device employing micro hydraulic is cut and is replaced the resin wheel cutting machine to be used for shearing the bundle silk, and the bundle silk is sheared efficient and convenient, does not produce the spark dust, has fundamentally improved working environment.

The specific embodiment:

Shown in Figure 2 as Fig. 1, the said a kind of metal wire rod hydraulic press-packing of the utility model comprises:

Main hydraulic cylinder 1 movable disk seat 2 movable disks 3 are fixing rotary disk basement about 5 knotting frames 6 cylinders 7 frames 8 of rotating disk 4 fixedly; Wherein, be provided with running mechanism 9 in the movable disk seat 2, about knotting be provided with micro hydraulic cutting machine 10. its characteristics in the frame 6 and be: 1, main hydraulic cylinder 1 is arranged in movable disk 3 and fixedly on the line of centres of rotating disk 4, when the piston rod of main hydraulic cylinder 1 advances, drive movable disk 3 by hinging pin shaft 11 direct promotion movable disk seats 2 and compress the coil of wire along coil of wire center line; Because the thrust of hydraulic system is big, control performance and maneuvering performance are far superior to screw thread pair, and the utility model packing function is compacted into closely knit length with the loose coil of wire and coils accurately.2, being contained on two d-axis of two pairs of travelling wheels of movable disk seat 2 of the present utility model, the assembly clearance of whole rotary disk basement only is made up of rolling bearing gap and wheel and orbit gap, rather than as the screw thread pair driving mechanism, also have transmission system gap, screw rod spindle nose roller bearing shop crack, four semiaxis assemblage gap bolt and nut gaps or the like (to see accompanying drawing 3,4), thus the rectilinear motion of the movable disk seat of this device reliable and stable.3, bundle silk of the present utility model cuts off and adopts micro hydraulic to cut 10, and as shown in Figure 5: cutting edge 2 is fixed on the hydraulic stem, starts high pressure micro hydraulic cylinder 1 and promotes hydraulic stem, just can drive cutting edge 2 fast shut-off and prick silk.
