Abstract
The present invention discloses a crossbeam punching pressure machine mainly comprising a main body of the pressure machine, a micro-motion device, a transmission system, a hydraulic pressure system, a pneumatic system, a lubricating monitoring system, an electric control system, etc., wherein the main body of the pressure machine mainly comprises an upper beam 1, a slide block 2, a vertical post 3, a base 4, a movable work bench 5, a tension pad 6, a clamping device 7 of the movable work bench, an upper mode clamping device 10, upper beating materials 11, etc. The crossbeam punching pressure machine makes four main gears divided into a left main gear set and a right main gear set which are synchronized through regulating middle gears and spline wheel hubs on the left and the right sides. The engaging error is less than 0.05mm. The crossbeam punching pressure machine uses treble monitoring for bearings of the transmission system. The first monitoring is formed by the method that all the bearings carry out pressure monitoring. The second monitoring is formed by the method that important bearings carry out lubricating monitoring with small flow rate. The third monitoring is formed by the method that slide bearings of an important connecting rod and a crank carry out temperature monitoring. Because the punching beam has the advantages of high quality and light weight, the loading capacity of a heavy cart is improved by about 25%.
Description
Technical field
The present invention relates to a kind of crossbeam punching out forcing press, the petrail punching out forcing press of loading and unloading before and after the double crank type on particularly a kind of girder assembly production line that is used for heavy-duty car factory.
Background technology
The present 4000T crossbeam punching out forcing press that uses in Jiangling Motor Co., Ltd. is the Japanese Xiao Song product of late 1980s, is machine one electricity one liquid integrated very strong product, is mainly used in the punching out of Medium Truck crossbeam.As be used for the punching out of heavy-duty car crossbeam, its ability and technical following deficiency arranged then: 1) integration capability deficiency.Existing forcing press blanking pressure and work capacity deficiency, punching out crossbeam beam slab thickness is less than 8mm, and length is less than 9m.And the crossbeam plate thickness of heavy-duty car is more than the 10mm, and length need become combination beam by overlapping riveted joint or assembly welding and just can be used for heavy vehicle more than 9m, and cost height, efficient are low.2) noise control difficulty.Existing forcing press main transmission complexity, gear, bearing are more, and the movement parts size is big, Heavy Weight, transmission accuracy is poor, and synchronism is bad, and the noise when causing forcing press work is more than 90dB.3) the lubricated monitoring of transmission system is unreliable.The lubricated monitoring of existing forcing press is the terminal monitoring of system, and each oil site is monitoring separately not, and this also is the reason that occurs damage of bearings often, and therefore lubricated monitoring system is reliable inadequately.4) fine motion system motor electric current is excessive.Existing forcing press is when die trial, die change or adjustment, and the fine motion motor needs frequent starting and braking, and its direct starting current is 600% of a rated current, and electric current is excessive, and too big to the electrical network impact, peripheral equipment all will be shut down when its started.
Summary of the invention
The present invention designs the crossbeam punching out forcing press that is applicable to heavy-duty car, mainly adopts following technical scheme:
1) for improving the work capacity and the blanking pressure of crossbeam punching out forcing press, satisfy the requirement of punching press heavy-duty car crossbeam integration capability, upper beam and base width that the present invention will have crossbeam punching out forcing press now increase more than the 0.5m, length increases more than the 2m, highly increase more than the 0.5m, weight increases more than 50%.Processed head and shoulders above existing processing, assembling and lifting transport capacity if the parts of large scale and weight are whole like this, so the present invention will put the beams in place and base respectively is divided into three by structural requirement, and they be combined with bolt and key.
2) for reducing the noise of transmission system, the present invention adopts the adjustable gear structure in assembling back, and the synchronism and the machining accuracy of raising gears engaged, four master gears are formed two primary cog set, guarantee that two every group master gear synchro-meshing errors are less than 0.05mm, the tooth thickness error of four master gears is controlled at 0.03～0.05mm, adjust the synchronism of two groups of gears after the assembling again, make four master gear synchro-meshing errors at 0.03～0.05mm, guarantee that four master gears transmit heavily loaded moment of torsion synchronously, reduce the noise of transmission system.
3) because transmission system of the present invention very huge, whole upper beam weighs more than 600 ton, the driving parts size is big, complex structure, after the damage of bearings dismounting very the difficulty, maintenance cycle is long, so the reliability of its lubricated monitoring system is very important.For improving the reliability of lubricated monitoring system, the present invention adopts triple lubricated monitoring systems.Be that each important oil site all is provided with lubricated low discharge, axle temperature and the triple monitoring of system's terminal pressure separately, lubricated low discharge monitoring system can show the flow and the lower bound warning of each oil site in real time, the axle temperature monitoring system can show the temperature and the upper limit alarm of each oil site bearing in real time, all centralized displaying is on display panel for the measured data of these triple monitoring, and result of use is very good.
4) be to overcome the super-high-current problem that the fine motion motor produces when die change, die trial or adjustment; the Starting mode of fine motion motor of the present invention adopts soft starting mode; the soft start current limliting can motor FLA 50%～600% between regulate, the current limliting time can be regulated between 0～30 second simultaneously.Reached the rated speed state in case controller detects motor, output voltage will automatically switch into total head output.
5) for improve to concentrate monitoring control ability, the present invention adopts touch screen technology will have the automation dish of forcing press and the setting on the main controlling board and function for monitoring, part operation function and forcing press Stateful Inspection function etc. now and all is pooled on the multi-touch screen screen operation CRT.Replace original button signal with touch signal, becoming has the operating of contacts signal to be contactless operation.Touch the corresponding button as required and turn over to respective picture, at the feedback control function and the sequential control function of touch-screen, set various functional pictures can arbitrarily be accessed by the operator, realize the concentrated supervision control to equipment control, are convenient to fault diagnosis.
The present invention compares with existing forcing press, control system is more advanced, monitor more concentrated, handled easily and maintenance, noise is low to be reached below the 72dB, and more reliable safety monitoring system is arranged, production efficiency is higher, the output of punching out beam can improve twice, and 19.8 ten thousand heavy goods vehicles crossbeams can be provided every year, and punching out longeron cost reduces about 30% than original combination longeron.Because the quality height of punching out beam of the present invention, in light weight can make the lifting capacity of heavy goods vehicles improve about 25%.The present invention also can improve the localization rate of parts and components of heavy-duty car equipment, substitutes import, saves nearly ten million dollar of foreign exchange for country is annual.
