Abstract
The utility model relates to a contracting fixture of a traction node of a linear motion actuator radial steering frame, which comprises an extruding element used for extruding the traction node and a contracting element used for bearing the traction node, wherein, the contracting element is a cylindrical workpiece, the upper part of a through hole of the cylindrical workpiece is contracted in the shape of a flare, and the lower part of the contracting element is also provided with a collection guide element. A guide sleeve of the traction node is contracted in a whole by utilizing the extruding tool and the contracting tool, thereby guaranteeing the perfect match of the external sleeve with the rubber, removing the residual stress of the rubber, and ensuring that the traction node meets the requirements of the omnidirectional rigidity match and the fatigue lifetime.
Description
Technical field
The utility model relates to a kind of railcar process equipment with workpiece, specifically, relate to a kind of linear electric motors radially the phase inversion frame with the overall shrinkage frock of drawing node.
Background technology
Therefore the vibration of the linear electric motors radial steering of railcar itself has particularity, and applied various traction nodes have its particularity, for the rigidity coupling of node with have specific (special) requirements fatigue life.Yet existing traction node still has problems after at the characteristic changing structure of linear electric motors, traction electric machine generally is to be made of overcoat, mandrel and the rubber of filling between the two, mode with sulfuration is produced, in the process of sulfuration, rubber must have certain amount of contraction, if and the size of metal-coating is adjusted, can not eliminate the participation stress of rubber, thereby can not adapt to the needs of use.
The utility model content
The purpose of this utility model is can not adapt to the radially deficiency of hitch frame use needs of linear electric motors at what existing traction node existed, and a kind of novel contraction frock that is used for the traction node is carried out post-production is provided.
The technical solution of the utility model is: a kind of linear electric motors radial steering contraction frock of traction node, comprise an extrusion that is used to push the traction node, and the contractibility of a support traction node, described contractibility is the workpiece of a tubular, and the top flue of this cylindrical work pieces through hole shrinks.
Preferably, the below of described contractibility also is provided with the collection guide.
Preferably, described extrusion is cylindrical, and columniform lower bottom part is provided with and draws the pressure edge that the overcoat of node is complementary.
The beneficial effects of the utility model are: utilize compression tool and pucker tool, fairlead to the traction node carries out overall shrinkage, thereby make perfect cooperation between overcoat and the rubber, eliminate the residual stress of rubber, order traction node can satisfy the Rigidity Matching and requirement fatigue life of all directions.

Fig. 4 is the vertical view of the contractibility of the utility model specific embodiment.
The specific embodiment
Specific embodiment of the utility model as shown in Figures 1 to 4, a kind of linear electric motors radial steering contraction frock of traction node, comprise an extrusion 3 that is used to push traction node 4, and the contractibility 2 of a support traction node 4, described contractibility 2 is the workpiece of a tubular, and the top flue of this cylindrical work pieces through hole shrinks 7.The below of described contractibility also is provided with collects guide 1.Described extrusion 3 is cylindrical, and columniform lower bottom part is provided with and draws pressure that the overcoat of node is complementary along 5.
As shown in Figure 1, during work, traction node 4 is positioned over tubaeform contraction 7 places of contractibility 2, subsequently, extrusion 3 begins the family extruding from the top, the pressure of extrusion 3 is pushed down the overcoat that draws node along 5 correspondences, presses the mandrel that withstands the traction node along the depressed part 6 of 5 central authorities.Along with the carrying out of extruding, the overcoat of traction node begins to shrink.Traction node 4 after contraction machines skids off and is collected from collecting guide 1.
Claims (3)
1, a kind of linear electric motors radial steering contraction frock of traction node, it is characterized in that: comprise an extrusion that is used to push the traction node, and the contractibility of a support traction node, described contractibility is the workpiece of a tubular, and the top flue of this cylindrical work pieces through hole shrinks.
2, the linear electric motors radial steering as claimed in claim 1 contraction frock of traction node, it is characterized in that: the below of described contractibility also is provided with the collection guide.
3, linear electric motors radial steering as claimed in claim 1 is with the contraction frock of traction node, and it is characterized in that: described extrusion is cylindrical, and columniform lower bottom part is provided with and draws the pressure edge that the overcoat of node is complementary.
