Description
Technical field：
The present invention relates to forging machine tool technical fields, and in particular to a kind of enclosed mechanical press hydraulic-driven exchanges automatically
Workbench.
Background technology：
Pallet changer is because being capable of easily more mold exchange or parts to be processed, therefore have in enclosed mechanical press
It is widely applied.But existing pallet changer is in actual use, through often will appear influence machine particularly after long-time use
A series of problems of bed normal use, forged part quality and production efficiency.
As shown in figures 1 to 6, be pallet changer that mechanical press generally uses, existing pallet changer be primarily present with
Lower problem：(1) existing pallet changer when moving, the problem of idler wheel poor synchronization.Particularly loading larger and/or work
It is particularly evident when environment is poor, such as when having greasy dirt in idler wheel running track, motor will appear when driving driving wheel rotation to be beaten
Sliding phenomenon, and then influence synchronism.(2) thus existing pallet changer causes there are the problem of guiding accuracy is low, stability is poor
Idler wheel is easier sideslip or damage.The removal and backhaul of existing pallet changer are driven using unilateral, are moved by motor band runner hub
It is dynamic, side gear is driven to rotate by gear and transmission shaft, there are gaps due to Gear Contact, are easy to cause error, make for a long time
With accumulated error is caused, unbalance loading and asynchronous problem are eventually led to.And idler wheel along concave guide rail be oriented to, when both sides driving wheel not
During synchronous, sideslip, wheel hub and concave guide rail hard friction centering can only be leaned on, for a long time using wheel hub and concave guide rail is caused quickly to grind
Damage, guiding accuracy reduce.Concave guide rail easily accumulates sundries, and is not easily cleaned, and steel guide rail surface screw has counterbore, long-time eye
Press fragile concave rail flatness and wheel hub roughness.(3) existing pallet changer stop position is inaccurate, influences positioning accurate
Degree.Traditional pallet changer removes or backhaul occurs signal close to being relied on during terminal close to switching and stops driving motor deceleration
Only, then pallet changer stops positioning, but limited block is easily deformed in use for some time by sliding shock limited block,
Eventually lead to stop position inaccuracy.(4) pallet changer can only be installed using the decision of fixed collision block, can not exchange makes
With pallet changer, Automatic change film and production efficiency are influenced.(5) pallet changer can not be accurately positioned and accordingly after removing
Clamp system causes pallet changer to be in active state, and when more mold exchange easily generates movement, causes mold positioning inaccurate
Really.(6) existing pallet changer is positioned using straight pin, for a long time using be easy to cause abrasion, backhaul position inaccurate,
Having changed mold every time needs to reposition, and straight pin using serious wear, is needed to change and repositioned for a long time.(7) it is existing
Pallet changer does not have corresponding overload protection arrangement, once overload uses, easily damages guide rail by pressure, destroys machine tool accuracy.(8) it passes
Pallet changer of uniting mostly replaces mold to be artificial, when needing replacing mold, after pallet changer removes, manually hangs away mold,
Then the mold more renewed will be positioned manually, clamp and proofread die location in replacement process, and after mobile working playback again
Again the center of mold and sliding block is proofreaded, often positioning accuracy is not allowed after pallet changer positioning pin is worn, and to be weighed
It resumes classes pair, whole process is bothersome laborious, and the degree of automation is low, it is impossible to meet mechanical press to automation, intelligent production line
The demand of Automatic Exchange Work Benche.
And now as manufacturing industry fast development and market keen competition need, improve forging and punching parts precision, matter
Amount and production efficiency preferentially select as producible corporationsípurchases equipment.And mechanical press realize it is efficient, accurate, reliable and stable,
Intelligent automation line is Development Trend of Key Technology, proposes requirements at the higher level to mechanical press pallet changer in this way --- it solves
Efficiently, the problem of precision, stability, intelligence, automatic production line
Invention content：
The purpose of the present invention is exactly in order to make up for the deficiencies of the prior art, to provide a kind of enclosed mechanical press hydraulic pressure and drive
Dynamic Automatic Exchange Work Benche, it, which has, is oriented to accurate, accurate positioning, and displacement distance is accurate, while possesses overweight detection alarm work(
Can, have positioning, clamping and interlock function after removal, can realize the automatic function of replacing workbench.Improve exchange work
The speed of platform more mold exchange, repetitive positioning accuracy, stability, reliability are, it can be achieved that intelligence, the automation of unit or production line
Control the advantages that extending pallet changer service life and improve forged product quality, solves in the prior art ask
