Abstract
The utility model discloses an improved hydraulic cylinder piston rod, a groove is arranged at the periphery of one end of the hydraulic cylinder piston rod, a brazing layer is arranged inside the groove, the thickness of the brazing layer is larger than the depth of the groove, and the brazing layer is used for guidance. In order to strengthen the welding, the axial length of the brazing layer is larger than the axial length of the groove. Two grooves are selected for optimization. A sealing groove is arranged between two sections of brazing layers. The shape of the axial cross section of the groove is rectangular, semicircular or inverted trapezoidal. The outer peripheral face of the brazing layer is a polished surface. Tin-bronze welding wires are used as surfacing materials for the brazing layer. Due to the adoption of the tin-bronze welding wires as the surfacing materials, the improved hydraulic cylinder piston rod has small friction force, high hardness and excellent anti-abrasion performance, excellent corrosion resistance, high loading capacity and long service life and greatly reduces the scuffing problems.
Description
Technical field
The utility model relates to hydraulic pressure installation, is specifically related to a kind of hydraulic cylinder piston rod of improvement.
Background technique
The piston rod that the oil hydraulic cylinder of existing bender is used all is to adopt nonmetallic material to lead.The bearing strength of finding this type of guide ring in the use is low, a little less than the anti-bias load ability.And wearing and tearing are accelerated when temperature raises, and guiding descends with bearing value, makes its lost of life.
The model utility content
The utility model is in order to overcome the deficiency that above prior art exists, and a kind of hydraulic cylinder piston rod of simple and reasonable, intensity is high, the life-span is long improvement is provided.
The purpose of this utility model realizes by following technological scheme: the hydraulic cylinder piston rod of this improvement, it is characterized in that: the periphery of an end of hydraulic cylinder piston rod has groove, be provided with braze layer in groove, the thickness of braze layer utilizes this braze layer to lead greater than the degree of depth of groove.
In order to make welding more firm, the axial length of described braze layer is greater than the axial length of groove.
According to the needs that reality is used, described groove can be one, two or more.Groove is preferably two.Be seal groove between two sections braze layers.
The axial cross section of described groove is shaped as rectangle, semicircle or trapezoidal.
The outer circumferential face of described braze layer is a burnishing surface.
Described braze layer adopts the tin bronze welding wire to make resurfacing welding material.
The utility model has following advantage with respect to prior art:
One, the braze layer of the hydraulic cylinder piston rod of this improvement adopts the tin bronze welding wire to make resurfacing welding material, and frictional force is little, the hardness height, and wear resistance is good;
Two, be difficult for generation and kill phenomenon;
Three, good corrosion resistance;
Four, bearing capacity height;
Five, long service life.
Description of drawings
Fig. 1 is the structural representation of the hydraulic cylinder piston rod of a kind of improvement of the present utility model.
Fig. 2 is the A partial enlarged drawing of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The hydraulic cylinder piston rod 1 of improvement as shown in Figure 1, the periphery of one end of hydraulic cylinder piston rod 1 has groove 2, and the axial cross section of groove 2 is shaped as trapezoidal, is provided with braze layer 3 in groove 2, the outer circumferential face of braze layer 3 is a burnishing surface, utilizes this braze layer 3 to lead.Braze layer 3 adopts the tin bronze welding wire to make resurfacing welding material.
As shown in Figure 2, the thickness of braze layer 3 is greater than the degree of depth of groove 2.In order to make welding more firm, the axial length of braze layer 3 is greater than the axial length of groove 2.
According to the needs that reality is used, groove 2 is two.Be seal groove 4 between two sections braze layers 3.
The hydraulic cylinder piston rod 1 of this improvement is braze layer 3 and oil hydraulic cylinder inwall contact matching in reciprocating using process, and frictional force is little, hardness is high, wear resistance is good, be difficult for generation kills phenomenon, good corrosion resistance, bearing capacity height, long service life.
Above-mentioned embodiment is a preferred embodiment of the present utility model; can not limit claim of the present utility model; other any change that does not deviate from the technical solution of the utility model and made or other equivalent substitute mode are included within the protection domain of the present utility model.
