Description

A kind of novel perforations pin cleaning plant

Technical field

The utility model relates to field of metallurgical equipment, for the working surface cleaning of two moving metal extrusion press peckers, is a kind of novel perforations pin cleaning plant.

Background technology

In the extruding metal process, need to be cleared up pecker, remove the glutinous metal residues stayed on pecker, to guarantee normally carrying out of follow-up extruding metal operation.Existing pecker cleaning plant is when the cleaning pecker, and very large moment is born in driving and coupling part, not only makes connecting portion too huge, and has affected cleaning effect, has reduced service life.

The utility model content

The purpose of this utility model is to provide a kind of novel perforations pin cleaning plant, in the effective removal that realizes the pecker metal residues, reduce the stressed of feeder, improved stability and the reliability of pecker cleaning plant, reduce the size of attaching parts, extended service life.

The technical solution of the utility model is a kind of novel perforations pin cleaning plant, which comprises at least feeder, cleaning plant, gland, pressure ram, recipient and pecker, gland, pressure ram and recipient are fixed on extruder, it is characterized in that: feeder is fixed on gland, the swing arm of feeder can freely swing centered by gland, and the swinging end of swing arm is fixedly connected with the cleaning support of cleaning plant; Shift(ing) ring is arranged in the endoporus of cleaning support, spring by axial compression shift(ing) ring and the cleaning support between, the cleaning ring is fixed on shift(ing) ring near on the end face of recipient, locating ring is fixed on the end face of cleaning ring, shift(ing) ring, spring, cleaning support, locating ring and cleaning ring form cleaning plant jointly, and pecker can be through the endoporus of cleaning plant.

Described feeder comprises pedestal, drive unit and swing arm; Pedestal is fixedly connected with gland; One end of swing arm and pedestal are hinged fixing, and the other end is swinging end, with cleaning plant, is fixedly connected with; The body of drive unit and pedestal are hinged fixing, and its drive end and swing arm are hinged fixing.

Described swing arm is bent to form " C shape " structure through five times, and end is the level of state.

Described drive unit is pneumatic cylinder or hydraulic cylinder.

Characteristics of the present utility model are by having increased spring and shift(ing) ring, make cleaning plant in scale removal process, frictional force that will be larger with strike off that power passes to recipient and pressure ram bears, make feeder not bear frictional force and strike off power, can meet the requirement of metal residues on the Automatic clearance pecker simultaneously; This novel perforations pin cleaning plant weight is little, cost is low and stable performance, and then has extended the service life of whole device.

In figure: 1, feeder; 2, cleaning plant; 3, gland; 4, pressure ram; 5, recipient; 6, pecker; 11, pedestal; 12, drive unit; 13, swing arm; 21, shift(ing) ring; 22, spring; 23, cleaning support; 24, locating ring; 25, cleaning ring.

The specific embodiment

As shown in Figure 1, feeder 1 is to consist of pedestal 11, drive unit 12 and swing arm 13, and pedestal 11 is fixedly connected with the gland 3 of extruder.

Swing arm 13 is bent to form " C shape " structure through five times, and end is swinging end, and is the level of state, and the front end of swing arm 13 and pedestal 11 are hinged fixing, and swing arm 13 ends are fixedly connected with cleaning plant 2.

Drive unit 12 is hydraulic cylinder or pneumatic cylinder, and its cylinder body end and pedestal 11 are hinged fixing, and lever end and swing arm 13 are hinged fixing, and drive unit 12 can drive swing arm 13 to freely swing around gland 3.

As shown in Figures 2 and 3, cleaning plant 2 be by, shift(ing) ring 21, spring 22, cleaning support 23, locating ring 24 and cleaning ring 25 form jointly, and shift(ing) ring 21 is arranged in the internal holes of cleaning support 23, and between shift(ing) ring 21 and cleaning support 23, axial compression has spring 22.

Cleaning ring 25 is fixed on shift(ing) ring 21 near on the end face of recipient 5, on the end face of cleaning ring 25, also is fixed with locating ring 24.

Pecker 6 can be through the endoporus of cleaning plant 2.

Pressure ram 4 and recipient 5 all are fixed on extruder, and pressure ram 4 is consistent with the extruding center of recipient 5.

During work, at first, drive unit 12 drives swing arm 13 and swings, make cleaning plant 2 be admitted to extruding center, now, due to the effect of spring 22, shift(ing) ring 21 is positioned at initial position, between recipient 5 and cleaning plant 2, certain interval is arranged, and pressure ram 4 does not contact with cleaning plant 2 with pecker 6 yet.

As shown in Figure 4, when cleaning starts, pecker 6 advances, and the endoporus that passes cleaning plant 2 advances, and shift(ing) ring 21 Compress Springs 22 advance, and locating ring 24 contacts with recipient 50 with cleaning ring 25; Pecker 6 moves on through cleaning ring 25.

Now, cleaning ring 25 bears very large frictional force, and this frictional force passes to recipient 5 by locating ring 24, and cleaning support 23 only bears less spring force in the horizontal direction with feeder 1, and stressing conditions is good.

As shown in Figure 5, pecker 6 retreats, and drives that cleaning plant 2 retreats simultaneously and contacts and stop motion with pressure ram 4; Pecker 6 continues to retreat, cleaning ring 25 metal residues that will strike off on pecker 6.

Now, cleaning ring 25 bears the very large power of striking off, and this strikes off power and passes to pressure ram 4 by shift(ing) ring 21, and cleaning support 23 does not bear with feeder 1 power of striking off in the horizontal direction, and stressing conditions is good.

When pecker 6 exits cleaning plant 2 fully, the metal residues on pecker 6 strikes off complete, and the drive unit 12 in feeder 1 will drive swing arm 13, and then drives cleaning plant 2 and leave extruding center, recovers initial station.
