Abstract
The utility model relates to an inner pipe of an oil pressure butter, which is characterized in that a metal membrane is plated on the inner pipe of the oil pressure buffer. As plating technology is adopted to replace the traditional technology for heating processing, the surface plating thickness is easier to control, and the hardness can achieve the required range of heating processing hardness; and the unstable inner pipe size caused by heating processing deformation can be avoided as well, and the variable quantity of the cylindricity of the inner wall of the inner pipe before and after a metal layer is plated is obviously less than that of the cylindricity of the inner wall of the inner pipe before and after the heating processing so that the matching size of an inner hole an a piston is easier to control, therefore, the quality consistency of the buffer can be guaranteed.
Description
Technical field
The utility model relates to pipe in a kind of hydraulic buffer, is specially and in hydraulic buffer, manages metal-coated membrane.
Background technique
Development along with industrial technology; Increasing traditional processing method is replaced by automation; People are more and more stronger to the requirement of production capacity; The right the simplest method of production capacity that increases is exactly to improve the service speed of machine, but its result often causes the shortcoming of the damage aggravation of excessive vibrating noise, machine and product.And, cause the loss that to retrieve because excessive impact force can make that Security significantly reduces; Use the industry oil compression buffer can provide smooth-going linearity to slow down in the place that needs absorb kinetic energy or impact force; Steadily and quietly stop or changing the moving direction of workpiece with minimum strength, also can perfect increase production capacity and make production line and operator's safety is protected.
Hydraulic buffer is widely used in: mechanism hand, taking-up arm, feeder apparatus, wire mark machine, pad printing machine, conveyor, haulage machinery, electric mechanical; Laboratory, teaching equipment, machine tool, food packing machine, rubber and plastic machinery; Steam turbine car manufacturing industry, carpenter, building machinery, air traffic industry; National defense and military equipment, health care equipment, environmental protection equipment.
The benefit of hydraulic buffer can be generalized into following points: enhance productivity; The prolonged mechanical life-span; Simplify Machine Design; Reduce maintenance cost; Reduce vibrating noise.
The major part hydraulic buffer is equipped with interior pipe, and the matching gap of interior pipe oil drainage hole quantity, size and arrangement mode equidimension and piston and interior pipe is for producing the key of damping force, so interior pipe quality is the core of decision cushioning effect; Pipe all adopts heat treated mode to improve interior pipe wear resistance and intensity in the general buffer in market; But control because of thermal effectiveness is difficult (like hardness and thin hardened layer); Pipe size distortion in being prone to cause causes the mass stability because of interior pipe processing differentia influence buffer.
Summary of the invention
To above-mentioned defective, the technical problem that the utility model need solve provides pipe in a kind of stay-in-grade hydraulic buffer.
The scheme that the utility model solves the problems of the technologies described above is: pipe in a kind of hydraulic buffer, and in its surface plating layer of metal film, adopt coating technology to substitute traditional heat treatment process, generally adopt nickel plating or chromium plating.Because of plating mode overlay coating thickness more easy to control and hardness, pipe is unstable because of the size that heat treatment deformation caused in also can avoiding, and makes endoporus and piston fit dimension be easier to control, so can guarantee the quality conformance of buffer.
On the such scheme basis, described thickness of metal film is 3 μ m～60 μ m.
The technique effect of the utility model is following:
1. interior pipe nickel plating or chromium plating can reach the claimed range of heat treatment hardness;
2. metal cladding front and back inner tube wall cylindricity variable quantity is significantly less than the cylindricity variable quantity of heat treatment front and back inner tube wall.
Description of drawings
With pipe generalized section in the hydraulic buffer of metallic diaphragm.
Label among the figure:
1-interior pipe; 2-metallic diaphragm.
Embodiment
Shown in pipe generalized section in accompanying drawing has the hydraulic buffer of metallic diaphragm; Pipe in a kind of hydraulic buffer; Adopt nickel plating or chrome-plated process plating layer of metal film on its surface, this thickness of metal film is 3 μ m～60 μ m, and coating hardness is HV250 °～HV1300 °.
Coating in the utility model has replaced with the surface abrasion resistance property of managing in the heat treatment increase hydraulic buffer and the mode of intensity; Surface metal layer thickness and intensity are controlled easily; Overcome interior pipe because of dimensional changes that heat treatment deformation caused; Make the matching size of endoporus and piston be easier to control, the quality of buffer is kept consistency.Not only hardness is equal to heat treatment hardness, and the cylindricity variable quantity of metal cladding front and back inner tube wall is less than the cylindricity variable quantity of inner tube wall before and after the heat treatment.
Claims (3)
1. manage in a hydraulic buffer, it is characterized in that: in its surface plating layer of metal film.
2. pipe in the hydraulic buffer according to claim 1, it is characterized in that: described thickness of metal film is 3 μ m～60 μ m.
3. pipe in the hydraulic buffer according to claim 1 and 2, it is characterized in that: said metallic film is nickeling layer or chromium coating.
