Abstract
The utility model discloses an abrasion resistant heald lifting arm for a dobby, which belongs to the technical field of weaving machine components. The abrasion resistant heald lifting arm for the dobby comprises a heald lifting arm body as well as a junction part and a shaft hole arranged at two ends of the heald lifting arm body, wherein the shaft hole is internally provided with an oil-containing bearing; a U-shaped groove is formed in the junction part; the U-shaped groove is internally provided with a replaceable abrasion resistant pad; the abrasion resistant pad is made of nylon; the junction part and the shaft hole are integrally formed in the heald lifting arm body. By adopting the heald lifting arm, the abrasion resistance of a conventional heald lifting arm for the dobby is improved, the service life of the heald lifting arm is prolonged, the heald lifting arm is prevented from being frequently replaced, the production efficiency of a weaving machine is improved, the production cost of companies is lowered, and meanwhile, the heald lifting arm does not need to change the structure of the conventional heald lifting arm and is easy to use and convenient to popularize.
Description
Technical field
The utility model relates to a kind of heald lifting arm, more particularly, relates to a kind of antiwear dobbies heald lifting arm.
Background technology
Dobbies is to control the key device of weaving loom, and shedding mechanism (shedding mechanism) is wherein the topmost executing agency of dobbies, determines the stationarity of weaving loom motion and the quality of fabric tissue.The effect of shedding mechanism is the Changing Pattern interweaving according to fabric organization chart's upper warp and woof, drives in time according to the order of sequence warp thread to move up and down, and forms shed open, wait for that weft yarn enters after shed open, two-layer warp thread alternatively up and down again, reciprocity position, form new shed open, so iterative cycles, can form fabric.
Heald lifting arm is the vitals on shedding mechanism, is its important part, for driving the warp thread formation shed open that moves up and down.Existing heald lifting arm (221 type dobbies heald lifting arm) in use for some time, generally can produce comparatively serious wearing and tearing, affects the stability of weaving loom work and the quality of fabric, can only entirety change, to ensure the normal operation of weaving loom.And on a dobbies, often need dozens of heald lifting arm, integral replacing heald lifting arm must bring the more wasting of resources and higher production cost, cause economic loss to weaving enterprise; In addition, the replacing operation of heald lifting arm is comparatively loaded down with trivial details, and the length that expends time in, changes heald lifting arm continually, will inevitably affect the production efficiency of enterprise, affects the production schedule of enterprise.
Summary of the invention
1. the technical problem that utility model will solve
The purpose of this utility model is to overcome the deficiency that existing dobbies heald lifting arm wears no resistance, service life is short, need frequently change, a kind of antiwear dobbies heald lifting arm is provided, the technical scheme that adopts the utility model to provide, improve the ABRASION RESISTANCE of traditional dobbies heald lifting arm, thereby extend its service life, avoid the frequent replacing of heald lifting arm, improved the production efficiency of weaving loom, saved the production cost of enterprise; Meanwhile, the utility model is without the structure that changes traditional heald lifting arm, easy to implement, is convenient to promote.
2. technical scheme
For achieving the above object, the technical scheme that the utility model provides is:

Further, the material of described anti-abrasion pad is nylon.
Further, described junction surface and axis hole are shaped on heald lifting arm body.
3. beneficial effect
The technical scheme that adopts the utility model to provide, compared with existing known technology, has following beneficial effect:
(1) the antiwear dobbies heald lifting arm of one of the present utility model, it comprises heald lifting arm body, is located at junction surface and the axis hole at heald lifting arm body two ends, in axis hole, be provided with oiliness bearing, improve the lubricity that heald lifting arm rotates, the wearing and tearing of heald lifting arm are reduced, and oiliness bearing occurs, after wearing and tearing, only needing to change oiliness bearing, has reduced the maintenance cost of heald lifting arm; Junction surface is provided with " U " shape groove, in " U " shape groove, is provided with removable anti-abrasion pad, and anti-abrasion pad can regularly replace, and changes simple and conveniently, and with low cost, and replacing speed is fast, can affect hardly the production efficiency of weaving loom;
(2) the antiwear dobbies heald lifting arm of one of the present utility model, the material of its anti-abrasion pad is nylon, nylon tool has good wearability and corrosion resistance, has greatly improved the service life of anti-abrasion pad; And nylon is easy to moulding, make anti-abrasion pad easily manufactured, with low cost.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of antiwear dobbies heald lifting arm of the present utility model.
Label declaration in schematic diagram:
1, heald lifting arm body; 101, junction surface; 102, axis hole; 2, oiliness bearing; 3, anti-abrasion pad.
Detailed description of the invention
For further understanding content of the present utility model, in conjunction with the accompanying drawings and embodiments the utility model is described in detail.
Embodiment
In conjunction with Fig. 1, the antiwear dobbies heald lifting arm of one of the present embodiment, comprise heald lifting arm body 1, be located at junction surface 101 and the axis hole 102 at heald lifting arm body 1 two ends, junction surface 101 and axis hole 102 are shaped on heald lifting arm body 1, particularly, heald lifting arm body 1 can adopt punching press or casting integrated moulding, sound construction, technique is simple, is suitable for batch production.Axis hole 102 is for matching with heald lifting arm rotating shaft, in heald lifting arm motion process, be very easily worn, for reducing the wearing and tearing probability of axis hole 102, in axis hole 102, be provided with oiliness bearing 2, this oiliness bearing 2 adopts powder metallurgical technique to make, in it, can contain the lubricating oil of 10%～40% volume fraction, fuel feeding voluntarily, improve the lubricity that heald lifting arm rotates, the wearing and tearing of heald lifting arm are reduced, and oiliness bearing 2 occurs after wearing and tearing, only need to change oiliness bearing 2, reduce the maintenance cost of heald lifting arm, simultaneously, it is low that oiliness bearing 2 has cost, energy absorbing, noise is little, can in the longer working time, not add lubricated wet goods feature, be specially adapted to the working environment of weaving loom, reduce textile industry noise, improve spinstry environment.Junction surface 101 is provided with " U " shape groove, specifically in the present embodiment, should be provided with two by " U " shape groove, " U " shape groove is for being connected with metal contiguous block, in swing process, " U " shape groove is very easily wearing and tearing also, for avoiding the junction surface 101 of directly wearing and tearing, in " U " shape groove, be provided with removable anti-abrasion pad 3, anti-abrasion pad 3 can regularly replace, and changes simple and convenient, and with low cost, replacing speed is fast, can affect hardly the production efficiency of weaving loom; In addition, the material of anti-abrasion pad 3 is nylon, and nylon tool has good wearability and corrosion resistance, has greatly improved the service life of anti-abrasion pad 3; And nylon is easy to moulding, make anti-abrasion pad 3 easily manufactured, with low cost.
