All-loading coach body kind is more, is usually formed by numerous rectangular square tube weldings, in the welding process, rectangle
Size, the precision of pipe will will have a direct impact on vehicle weld size and quality, serious to cause overall dimensions of a car that cannot be reached with intensity
To design requirement, there are security risks.
The blanking that rectangular square tube is carried out using the provided by the invention kind of full-automatic straight material blanking machine of rectangular square tube, is subsequently made
With necessarily will produce corresponding component aging, damage, failure etc. in the process.The failure effect of component arrives whole system in order to prevent
Normal use, the parts of blanking machine make to be bolted connection, and facilitate the replacement of inoperative component.In addition, associated bearings, rolling
The components such as wheel, have carried out meeting the lubricant method of the part requirement and be periodically lubricated to it, reduced the abrasion journey of tooling
Degree, extends its service life.
The provided by the invention kind of straight material blanking machine of full-automatic rectangular square tube, by servo-control system, in conjunction with induction mechanism,
Pass through the cooperating of each component, the entire blanking process of realization rectangle cast raw material to finished product.And whole system can be
Arbitrary node suspend and recovery operation, and convenient in emergency circumstances pair setting the protection of whole system, entire body improves equipment operation
Safety.
The course of work of the provided by the invention kind of straight material blanking machine of full-automatic rectangular square tube is described below：Raw material
Feeding process it is as follows：Stock shelf monolithic 3 connects into a stock shelf by four tie-beams 12, and raw material 14 are positioned over feeding
On, include a steel wire rope 13 on each monolithic, motor 6 and speed reducer 8 are installed in stock shelf bottom, 6 output end of motor with subtract
8 input terminal of fast machine is connected by belt pulley system 7, and output end of reducer installs a minor sprocket 16.Stock shelf bottom installation one passes
Lever 10, drive link 10 is divided to be saved for two, is connect with bearing block 22 by link block 9 and is run through entire stock shelf, and is corresponding upper
An idler wheel 20 is installed at the position of rack monolithic 3, and idler wheel 20 is fixed 13 one end of steel wire rope, connected at the top of one stock shelf of the other end.
In addition there are also installed a big sprocket wheel 18, big sprocket wheel 18 is connect with minor sprocket 16 by chain 17.When the motor is energized, motor 6
Output can drive the rotation of 8 input terminal of speed reducer to lead to be the rotation of 8 output end minor sprocket 16 of speed reducer by belt pulley system 7
Crossing chain 17 drives big sprocket wheel 18 to be rotated with drive link 10, is further driven to the rotation of idler wheel 20；The rotation of idler wheel 20 can make steel wire rope
13 is wound on it, to make steel wire rope 13 shorten, will be lifted on raw material 14.It is higher than stock shelf trundle 23 when raw material 14 reach
When, raw material 14 can be slid by root and be blocked by block 21.15 height of assembly that gets stuck is adjustable, it is ensured that raw material 14 can press root successively
It slides into.Stock shelf feeding is completed at this time, and raw material 14 wait for further step, the inductor signal feedback of 21 lower portion of block installation
There are raw material states for induction.Then, the transmission process of raw material is as follows：There are former materials for 21 lower part inductor signal feedback of block
When material, 24 big end of rod for stiring materials of material toggling system 11 is fixed on frame, and cylinder 25 stretches out, and upwarps raw material provoking one, the original
14 blanking of material falls into 26 position of roller bearing.Pressing system 5 pushes down raw material 14 at this time.After pushing down about 2 seconds, feeding system is positioned
System 4 starts feeding to stock shelf end origin position, and inductor 27 is installed in this position, when sensing in the presence of material, positions feeding
Stop, pressing system 5 unclamps and retract the origin of positioning feed system, waits for next step.
Followed by scale sawing step.When raw material 14 are in 27 position of inductor, sizing feed system 2 is accurate
It is standby in place and origin position, the pressing system 5 of servo-control system control at this time clamps raw material 14 again, and allows and position feeding system
Raw material 14 are conveyed a regular length by system 4 again, and after conveying in place, sizing feed system 2 clamps raw material 14, are compressed
System 5 unclamps and returns to positioning 4 origin of feed system.Sizing feed system 2 is by 14 feeding of raw material to 1 sawing position of lathe
When, lathe 1 carries clamping system and clamps raw material 14, and lathe 1 starts sawing at this time, while sizing feed system 2 unclamps folder
Tightly, it is back to need to be clamped at sawing size the next time that whole system is set and waits for feeding；After the completion of a current sawing, lathe
1 clamping system unclamps, the feeding again of sizing feed system 2, so far recycles lathe 1 and carries clamping system clamping, sizing feed system
System 2 is back to next blanking demand size and waits for next processing program.
Incude cyclic program：When raw material 14 are gone out by 2 feeding of sizing feed system to except inductor 27, inductor 27
Feedback signal, whole system can start first step and second step, that is, raw material feeding with it is to be conveyed.Due to raw material
Length is fixed value, so whole system can be calculated according to the size of each whole different cultivars blanking saves raw material the most
Mode carries out blanking, and when single raw material length cannot meet any kind blanking, sizing feed system 2 can be by remaining original
Material material head takes out and abandons to ash can.And at the same time, positioning feed system 4 starts feeding to fixed position, scale
Feed system 2 returns to origin and clamps raw material.
By above technical scheme it is found that a kind of full-automatic rectangular square tube corner sawing machine of the present invention, can use digital control system
The feeding of the former manual operation of substitution and measurement save a large amount of action wastes, promote effective working time, improving production efficiency；
Operating personnel only carry out the feeding stacking of finished product simultaneously, save a labour personnel, reduce recruitment cost；Self reliant rebuilding
Digital control system for relatively external purchase of equipment, adapts to in-company demand, blanking is accurate, avoids the production of quality accident the most
It is raw；Each component use that designs and produces of system is bolted fastening, and rapid wear, trouble location can be replaced, be reduced in time
The cost of system follow-up maintenance.And centralized lubrication is used, to each component intermittent oiling, the service life of elongate member.
The present invention is not limited to the above embodiment, and embodiment is only exemplary, it is intended to for explaining the present invention, and cannot
It is interpreted as limitation of the present invention.
