Description
Technical field
The present invention relates to machinery field, and in particular to a kind of mechanical stop limiter for pressure forming machine.
Background technology
During pressure forming, especially in hydraulic extrusion press forming process, position control be it is very crucial, directly
The axial dimension of product is influenced, the axial dimensional errors scope of product is small to bring simplified technique, reduction processing, stock utilization
The high, benefit such as cost is low, the market competitiveness is strong.
In the prior art, the following two methods of generally use carry out extruding object spacing：
1. using hydraulic pressure combination electrical control is leaned on, the multiple elements such as proportioning valve, displacement sensor need to be increased, and had by fluid
The influence of the factors such as temperature, press deformation, control accuracy, the precision of control element is very big, it is not easy to realizes, and cost increase
Very much, and in hot extrusion influenced by the unstable of workpiece heat temperature, control is more complicated, and it is difficult effect to implement
Fruit is bad.
2. using the method with locating piece, this method can not be finely adjusted, and operation is extremely inconvenient, in product variety specification
When changing more, production efficiency is just seriously affected.
The content of the invention
For in the prior art the defects of, the main object of the present invention is to provide a kind of easy to operate, stable quality, cost
Low, practicable mechanical stop limiter.
Mechanical stop limiter provided by the invention includes：The left mechanism and right mechanism that are symmetrical set, screw, wedge,
Cross-arm, bottom plate；The left mechanism and right mechanism each include the cross-arm, screw and wedge；The wedge is two, respectively
The both ends of the screw of axial level are inserted in, one of wedge is fixed on the bottom plate below screw, another wedge screw thread connects
It is connected on screw；The cross-arm is set above the wedge, and the wedge top surface is to be inclined by end to the center of out screw rod axial direction
Oblique plane, the bottom surface of the cross-arm match setting with the wedge top surface.
The bottom surface of the cross-arm matches setting with the wedge top surface, namely the top surface of wedge is inclined-plane, the bottom surface of cross-arm
It is that the inclined-plane coordinated with wedge top surface is set, i.e. the centre of cross-arm bottom surface is plane, but its both sides is to incline from outside to inside to bottom
Oblique inclined-plane, cross-arm just form inverted trapezoidal mesa-shaped.
That is, the object for extruding is placed above cross-arm, and the raising and lowering of cross-arm is to rely on two
Wedge realizes towards and away from movement, and two wedges towards and away from movement is drive it by the rotation of screw
In wedge is opposite or dorsal glide is realized.
Further, above-mentioned mechanical stop limiter further includes：Screw rod transmission bar, connecting rod, transmission mechanism, motor；It is described
Screw one end is connected by gear transmission mode with the top of screw rod transmission bar；The bottom of the screw rod transmission bar of the left mechanism leads to
The first end for crossing angular wheel and connecting rod connects, and the screw rod transmission bar of the right mechanism and the motor axis connection of motor are described
Motor shaft is connected with the second end of the connecting rod by angular wheel；The axial direction of the connecting rod is horizontally disposed with.
Further, the angle of inclination of the top surface of wedge described in above-mentioned mechanical stop limiter is 5-15 °.Under normal conditions
Will be considered that only by single wedge move can cross-arm top surface run-off the straight, and actually by substantial amounts of practical operation
Experiment, when the top surface inclination degree of wedge is maintained at 5-15 °, in squeeze job especially in squeeze operation, cross-arm top surface meeting
Remain horizontal, therefore the present invention simple structure can realize that the accurate of squeeze job controls by doing so.
Further, above-mentioned mechanical stop limiter further includes：Match the upper cushion block and lower cushion block set；The lower cushion block is set
The top surface of the cross-arm is placed in, the cross-arm top surface is horizontally disposed with；The upper cushion block is arranged at the top of the lower cushion block；It is described
Upper cushion block and lower cushion block are provided with four groups.Its operation principle is moving toward one another between the two by upper cushion block and lower cushion block
Article to be extruded carries out squeeze job, and cushion block is set along extruding uniform plane, and carrying out extruding by cushion block can treat
It is more uniform to extrude article compression.
Further, in above-mentioned mechanical stop limiter, the bottom surface of the upper cushion block is provided with one layer of wearing layer, the underlay
The top surface of block is provided with one layer of wearing layer.Wearing layer can be antifriction metal (AFM) layer, such as copper, in connecing for cushion block and article to be extruded
It is in order to improve the service life of equipment, easy to maintenance that contacting surface, which sets one layer of wearing layer,.
Further, above-mentioned mechanical stop limiter further includes rotary encoder；The rotation angle of the motor passes through rotation
Encoder settings.By rotary encoder come realize the control of the rotation angle of motor can whole operation process it is electrified,
Operating personnel can complete the operation of the raising and lowering of cross-arm on the touchscreen.
In conclusion mechanical stop limiter provided by the invention can realize that bulk article axial dimension is stablized, can control
The precision of product processed is within 0.1mm, and from workpiece temperature, the influence of excircle dimension, forming pressure, and can also lead to
Cross electrical control and carry out trace regulation, substantially reduce labor intensity and human cost.
