Abstract
The utility model discloses a bracing bar for a surface colouration machining operation for piston ring spiral bracing springs, relating to the technical field of machining for piston ring spiral bracing springs. The bracing bar comprises a straight bar body and a connection lifting rope, wherein rope threading holes are arranged at the both ends of the straight bar body respectively, and the both ends of the connection lifting rope are separately connected with the two rope threading holes respectively. The bracing bar disclosed by the utility model can be used for machining a plurality of the piston ring spiral bracing springs simultaneously, and realizing the high efficiency of colouration.
Description
Technical field
The utility model relates to the processing technique field of piston ring helical supporting spring.
Background technology
In the processing of piston ring helical supporting spring, the client's proposition that has needs the requirement of sorrel or filemot piston ring helical supporting spring, for this reason; Existing manufacturing enterprise great majority adopt pit furnace, and perhaps other devices of heating carry out heat treated with piston ring helical supporting spring; Reaching painted purpose, but in these heating units, air can not produce complete convection current; Heat energy only depends on conduction or thermal radiation, and temperature is seriously inhomogeneous, when piston ring helical supporting spring is put into heating unit; The central point piston ring helical supporting spring is with very serious near the piston ring helical supporting spring aberration of furnace wall, and the product of producing is difficult to reach requirement of client, and; Piston ring helical supporting spring is prone to produce reaction with oxygen at the hot conditions lower surface, the piston ring helical supporting spring surface is produced oxidation takes place, and gets rusty easily; Also exist production efficiency low in addition, the phenomenon that tank liquor is difficult in maintenance.
In order to change the defective of prior art, the contriver proposes a kind ofly to adopt liquid high-temperature sub SODIUMNITRATE that piston ring helical supporting spring is carried out the working method of immersion treatment, and it is even to have a piston ring helical supporting spring surface chromaticness, the characteristics that the percentage of A-class goods is high.
Summary of the invention
The utility model purpose is to be the supporting piston ring helical supporting spring surface colour process operation strut of soaking technology.
The utility model comprises that the straight shape body of rod is connected lifting rope with one, at the two ends of the straight shape body of rod lacing hole is set respectively, the two ends of said connection lifting rope respectively with two detachable connections of lacing hole.
Take off an end that connects lifting rope earlier; The piston ring helical supporting spring that reaches 200 is set on the straight shape body of rod of a basic utility model; The connection lifting rope that to take off again reconnects; Lifting rope not only can prevent piston ring helical supporting spring slippage from the straight shape body of rod, also can will have in the straight shape body of rod immersion high-temperature sub SODIUMNITRATE liquid of piston ring helical supporting spring at middle the clamping hanger that connects lifting rope.The utility model can be processed many piston ring helical supporting springs simultaneously, can realize painted high efficiency.
Reduce to for the contact surface that makes the piston ring helical supporting spring and the straight shape body of rod and to contact, to improve the uniform coloring property of product, the said straight shape body of rod of the utility model is a flat, thickness≤2mm.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is that the A-A of Fig. 1 is to sectional drawing.
Embodiment
As shown in Figure 1, utility model is provided with a straight shape body of rod 1 and is connected lifting rope 2 with one, at the two ends of the straight shape body of rod 1 lacing hole 3,4 is set respectively, and the two ends that connect lifting rope 2 are respectively through hook and 3,4 detachable connections of two lacing holes.
As shown in Figure 2, the straight shape body of rod 1 is a flat, and thickness D is about 1.5 to 2mm.
Claims (2)
1. piston ring helical supporting spring surface colour process operation strut is characterized in that comprising that the straight shape body of rod is connected lifting rope with one, at the two ends of the straight shape body of rod lacing hole is set respectively, the two ends of said connection lifting rope respectively with two detachable connections of lacing hole.
2. according to the said piston ring helical supporting spring surface colour of claim 1 process operation strut, it is characterized in that the said straight shape body of rod is a flat, thickness≤2mm.
