Description
Technical field
The invention belongs to technical field of metallurgical equipment, are related to a kind of push rod bi-directional adjustable clamping device.
Background technique
The stretching that machine equipment is mainly used for coloured or ferrous metal Strip, pipe rod type material etc. is stretched, by producing metal
Raw certain elongation, not only plays the role of certain aligning and leveling, it is often more important that improve in metal to material
The stress distribution in portion improves the mechanical property of material.Currently, stretching-machine is wide in the application of metallurgy industry, aluminium and aluminium processing industry
It is general.Stretching-machine is to be treated by the several groups jaw in two heads after stretched part clamped, then is stretched to reach
Improve the purpose of inside workpiece stress distribution, jaw is most important to the uniformity of piece-holder, it directly affects workpiece drawing
Effect after stretching.Current most reasonable jaw clamping device is to realize with synchronous clamping with individually clamping the method that combines
Uniform clamping to workpiece is equipped with and the independent clamping cylinder of the one-to-one several groups of jaw, each clamping on synchronous beam
Cylinder is connected with a push rod, and the other end of push rod can be bonded with jaw rear surface；Synchronous beam or so respectively has a synchronized cylinder, with next
The entire synchronous beam movement of control.Since the length of push rod is generally longer, deformed after heat treatment it is larger, so the length of each push rod
Itself has error；And when clamping workpiece, push rod one end and jaw rear surface produce relative sliding to generate abrasion, lead
Push rod length is caused to change, in order to guarantee that the uniform clamping to workpiece must just be adjusted the length of push rod.It deposits at present
In two kinds of main clamping control modes: first is that independent clamping cylinder passes through again after synchronized cylinder pushes entire synchronous beam operation in place
Push rod pushes jaw to be clamped workpiece, and this mode is mainly used for clamping slab；First is that individually clamping cylinder first pushes push rod
It stretches out, then synchronized cylinder pushes entire synchronous beam movement until push rod is bonded with jaw rear surface again, and synchronized cylinder stops dynamic at this time
Make, pushed at high pressure jaw clamps workpiece on independent clamping cylinder, and this mode is mainly used for grabbing thin plates.To sum up, this requires push away
Bar will guarantee that the position of its front end face is identical at extended and retracted position, therefore push rod needs to carry out bidirectional modulation.Traditional
The few push rod regulating devices of clamping device, can only also push rod be carried out by having an other clamping device to be provided with push rod regulating device
It usually needs to synchronize beam when unidirectionally adjusting, and being adjusted entirely to remove, it is time-consuming and laborious.
Summary of the invention
The purpose of the present invention is to provide a kind of push rod bi-directional adjustable clamping device, the beneficial effects of the invention are as follows can be
The bidirectional modulation to push rod extended and retracted position is realized in the case where not removing any part, to guarantee jaw to workpiece
Uniformly clamp, it is simple to operate.
The technical scheme adopted by the invention is that including several push rods, several push rods are mounted on synchronous beam, each push rod
Both ends be separately connected a jaw and independent clamping cylinder, independent clamping cylinder driving push rod movement is to be tensioned to push jaw to clamp
Workpiece；It is also equipped with plate on each push rod, one group of front end double nut is installed at the screw thread of each push rod and one group of rear end is double
Nut, front end double nut and rear end double nut are located at the two sides of plate, and front end double nut and rear end double nut can be adjusted
Position on push rod；Synchronized cylinder, which connects synchronous beam, can drive synchronous beam to run, synchronized cylinder and independent clamping cylinder collective effect with
Realize that jaw treats the clamping of stretched part.
Further, when independent clamping cylinder driving push rod retracts, front end double nut is bonded with the front surface of plate, at this time may be used
The adjusting to pusher retracted position is realized by adjusting position of the front end double nut on push rod；When independent clamping cylinder driving push rod
When stretching, rear end double nut is bonded with the rear surface of plate, at this time can be by adjusting position of the rear end double nut on push rod reality
Now to the adjusting of push rod extended position, to guarantee the consistency of pusher retracted and extended position, and then guarantee jaw position one
It causes, the final uniform reliable grip realized jaw and treat stretched part.

Specific embodiment
The present invention is described in detail With reference to embodiment.
Push rod bi-directional adjustable clamping device of the present invention is as depicted in figs. 1 and 2, and several push rods 2 are mounted on synchronous beam 3,
The both ends of each push rod 2 are separately connected a jaw 1 and independent clamping cylinder 5, and push rod 2 and jaw 1 are separable, independent clamping cylinder 5
Driving push rod 2 is moved to push jaw 1 to clamp workpiece to be tensioned；
It is also equipped with plate 7 on each push rod 2, one group of front end double nut 8 and one group are installed at the screw thread of each push rod 2
Rear end double nut 6, front end double nut 8 and rear end double nut 6 are located at the two sides of plate 7, the double spiral shells of front end double nut 8 and rear end
Mother 6 can adjust the position on push rod 2；Synchronized cylinder 4, which connects synchronous beam 3, can drive synchronous beam 3 to run, synchronized cylinder 4 and individually
5 collective effect of clamping cylinder is to realize that jaw 1 treats the clamping of stretched part.
When independent 5 driving push rod 2 of clamping cylinder retracts, front end double nut 8 is bonded with the front surface of plate 7, can be led at this time
Cross position realization adjusting to pusher retracted position of the adjustment front end double nut 8 on push rod 2；When the driving of independent clamping cylinder 5 pushes away
When bar 2 stretches out, rear end double nut 6 is bonded with the rear surface of plate 7, at this time can be by adjusting rear end double nut 6 on push rod 2
The adjusting to push rod extended position is realized in position, to guarantee that push rod 2 retracts the consistency with extended position, and then guarantees jaw
1 position consistency, the final uniform reliable grip realized jaw 1 and treat stretched part.
The present apparatus can the position in the case where not removing any part by adjusting double nut easily realize push rod stretched
It is each to ensure that jaw is uniformly reliable to the clamping of workpiece height and width direction out with the bidirectional modulation of retracted position
Jaw uniform force, and it is simple to operate.
The above is only not to make limit in any form to the present invention to better embodiment of the invention
System, any simple modification that embodiment of above is made according to the technical essence of the invention, equivalent variations and modification,
Belong in the range of technical solution of the present invention.
