Description
Technical field
The utility model relates to a kind of friction plate, the air operated friction clutch of punching machine is generally divided into wet type and two kinds of dry type
Clutch.There is hydraulic oil inside wet clutch, friction plate engages friction under air pressure promotion in oil film, and dry clutch does not have
There is hydraulic oil, and pushes lower be frictionally engaged by air pressure.The importance of clutch in large-tonnage punch body depends on rubbing
The performance of pad.More particularly to a kind of large-tonnage clutch for puncher powder metallurgy frictional disk.
Background technique
In recent years, as Chinese punching machine machinery industry rapidly develops, punching machine industry downstream claimed range is wider, and punching machine has
Certain rigid demand characteristic.Heavy-duty machinery press machine and its covering production line, large-scale transfer press automobile panel are
The most important sheet metal part for indicating car mass, is the typical parts of large-scale stamping parts, and there are mainly two types of methods at present for production: one
It is to be equipped with automatic mechanical hand by more big heavy-duty machinery press machine, forms automatic flexible stamping line；Second is that application is big
The production of type multiple position press.Sheet Metal Forming Technology saves material and the energy due to having for processing than tradition machinery, high-efficient, to behaviour
Author's technical requirements are not high and can be made by various mold applications and be machined be unable to reach these advantages of product, because
And its purposes is more and more extensive.
Chinese patent 2012101437011, disclosed a kind of clutch friction plate, on clutch friction plate anchor ring
It is circumferentially equidistantly equipped with helicla flute, it is radial equidistantly equipped with through slot along clutch friction plate, it is radial etc. along clutch friction plate
Spacing is equipped with half through slot, and the through slot and half through slot are set in distance, and the through slot and half through slot connect with helicla flute.This
The wearability and thermal diffusivity of mechanism are relatively poor, and structure is complicated, and maintenance cost is high.
Company research and development technology personnel make thorough investigation and study and develop to large-tonnage clutch for puncher powder metallurgy frictional disk, the product
Precision is high, product structure is simple, advantage of lower cost, is matched in large-tonnage clutch, is wet in large-tonnage clutch for puncher
Formula multi-disc clutch and brake, this clutch and brake are combined into one, sensitive, clutch and brake inertia
Small, speed is fast, has reliable clutch and braking ability.Friction material is copper-base powder metallurgy, is immersed in diesel engine oil, and strong
Circulating cooling processed, therefore generate heat and wear small, long service life and market application prospect is extensive.
Summary of the invention
The utility model mainly solves the deficiencies in the prior art, provides a kind of performance for improving material, mentions simultaneously
Rise the large-tonnage clutch for puncher powder metallurgy frictional disk of product quality.
Above technical problems of the utility model are mainly solved by the following technical scheme:
Large-tonnage clutch for puncher powder metallurgy frictional disk, including pairing steel sheet, the pairing steel sheet inside are equipped with dress
Distribution, the surface and the back side of the pairing steel sheet are respectively equipped with copper-based liner, and the copper-based liner surface, which is equipped with, uniformly divides
Cloth by up time slot and inverse time slot phase composition arc groove.
Preferably, the pairing steel sheet is square and quadrangle chamfering.Its outer dimension by relative to assembly method
Shape determines there is unique trait.
Preferably, the arc radius of the up time slot and inverse time slot is 145~155mm, this arc radius is with diameter
Centering is uniformly distributed in arc-shaped on the basic circle of 235~245mm, and the groove width 1.1 of the up time slot and inverse time slot~
The arc groove of 1.3mm, 0.4~0.5mm of groove depth, up time slot and inverse time slot two-way each 48 are uniformly distributed.
Preferably, being equipped with oil-through hole 5, oil-through hole between 2 outer circle of corner location and copper-based liner of the pairing steel sheet 1
5 quantity is 4, is positioned by shape, cuts 42.4 hole 4- φ, while can be with the position of fixed friction piece.
Therefore, the large-tonnage clutch for puncher powder metallurgy frictional disk of the utility model, product is with oil-through hole and double circles
The characteristics of arc slot, by guaranteeing that there is thermal diffusivity, stationarity and peace in punching course to 100% detection is carried out before product export
Quan Xing, it is simple and reasonable for structure the features such as.With dynamic friction coefficient height and necessary thermal stability；Static and dynamic friction coefficient is close；It is resistance to
Mill property is good, and the service life is long；Good running-in ability；Good anti-card, stable driving torque and braking ability；Enough intensity,
It can bear higher operating pressure and speed；Corrosion resistance brakes uniform, smooth engagement is soft etc., is applicable in and uses the big of high load
Tonnage clutch for puncher uses field.
