Abstract

The utility model discloses a multi -purpose bending machine belongs to mechanical equipment technical field. This bender includes frame, hydro -cylinder, hydraulic pump, switching -over valve, hydro -cylinder upper end fixed connection in the frame, the direct fixed connection of hydro -cylinder pole on last cutting die, the hydro -cylinder sets up two at least, goes up the cutting die and bends length the most greatly divided by the value less than or equal to no. 2 of the figure gained of hydro -cylinder with what rice calculated, goes up that the cutting die is fixed down to be provided with cutting die under the assorted, is provided with the mould connecting hole under and on the cutting die at last cutting die. This bender is much higher than present bender precision of the same kind through advance copy bender bending precision to the span is 6 meters panels bends to the example, this bender can control the error at both ends within 1mm, this bender is after corresponding mould is connected in the configuration on last cutting die and cutting die down, can the mould pressing designs the work piece of shape.

Description

A kind of Multi-purpose bending machine
Technical field
The utility model relates to a kind of bender, and particularly a kind of Multi-purpose bending machine, belongs to mechanical equipment technical field.
Background technology
Bender is a kind of common plate forming machinery, can as the equipment of the corresponding part of compacting after mixing corresponding mould, current large-tonnage bender take hydraulic pressure as main power source, hydraulic power bender generally conventional is at present general higher at the bending precision of length less than 3 meters, but after 3 meters of length, precision generally can decrease, such as certain 6 meters of hydraulic bending press is when the sheet material of bending 6 meters, the error at two ends can reach larger, greatly affect the bending and molding quality of sheet material, this is relevant to the syndeton of bender, current bender oil cylinder and upper slitter mould holder syndeton complexity, adopt in the longitudinal direction and be spliced, sometimes guide rail guiding is also relied on, and also often connector is equipped with on upper cutting die length direction, the deviation of these structures in assembling and running all can cause pressing down in process at upper cutting die precision produces the problems referred to above, and commercially available bender often can only be used for bending at present, function singleness.
Summary of the invention
The purpose of this utility model is to overcome the problems referred to above existed in existing bender, provides a kind of Multi-purpose bending machine.
For realizing the purpose of this utility model, have employed following technical scheme: a kind of Multi-purpose bending machine, comprise frame, oil cylinder, hydraulic pump, reversal valve, described cylinder upper end portion is fixedly connected in frame, cylinder rod is directly fixedly connected on cutting die, described oil cylinder at least arranges two, the maximum bending length that upper cutting die calculates with rice is less than or equal to two divided by the value of the number gained of oil cylinder, the lower cutting die matched is fixedly installed under upper cutting die, upper cutting die and lower cutting die are provided with mould connecting hole, further, the oil-in of described oil cylinder is all positioned at the same valve chamber of reversal valve, oil-out is all connected in the same valve chamber of reversal valve, further, described upper cutting die is fixedly connected with cylinder rod by flange, oil cylinder distributes along upper cutting die intermediate symmetry, the oil cylinder of ragged edge is 1/2nd of the spacing of two adjacent oil cylinders to the distance of upper cutting die end, further, described bender is six meters of benders, upper cutting die is connected with three oil cylinders, one of them oil cylinder is positioned in the middle of cutting die, two other oil cylinder distributes along intermediate symmetry, the oil cylinder of ragged edge is 1/2nd of the spacing of two adjacent oil cylinders to the distance of upper cutting die end.
Positive Advantageous Effects of the present utility model is: the oil cylinder of this bender is directly fixedly connected with upper cutting die by flange, connector is few, assembly precision is high, according to bender length, oil cylinder quantity is reasonably set, current similar bender precision is much higher than through testing this bender bending precision, be 6 meters of sheet metal bending for span, this bender can control error at two ends within 1mm, the raising of precision can improve the bending quality of sheet material, reduce the waste of sheet material, after this bender configures and is connected corresponding mould on upper cutting die with lower cutting die, can the workpiece of extruded designs because shape, mold pressing precision can be realized equally high.
Accompanying drawing explanation
Fig. 1 is schematic front view of the present utility model.
Fig. 2 is schematic side view of the present utility model.
Detailed description of the invention
In order to explain enforcement of the present utility model more fully, provide embodiment of the present utility model.These embodiments are only to elaboration of the present utility model, do not limit scope of the present utility model.
Explanation detailed further to the utility model by reference to the accompanying drawings, shown in the drawings of a 6m bender, have employed three oil cylinders, is respectively labeled as: 1: hydraulic pump in accompanying drawing; 2: reversal valve; 3: frame; 4: oil cylinder; 5: upper cutting die; 6: lower cutting die.As shown in drawings, a kind of Multi-purpose bending machine, comprise frame 3, oil cylinder, hydraulic pump 1, reversal valve 2, 4 are depicted as an oil cylinder, oil cylinder 4 upper end is fixedly connected in frame 3, cylinder rod is directly fixedly connected on cutting die 5, oil cylinder at least arranges two, the maximum bending length that upper cutting die calculates with rice is less than or equal to two divided by the value of the number gained of oil cylinder, upper cutting die 5 is fixedly connected with cylinder rod by flange, oil cylinder distributes along upper cutting die intermediate symmetry, the oil cylinder of ragged edge is 1/2nd of the spacing of two adjacent oil cylinders to the distance of upper cutting die end, for the 6m bender of the present embodiment, upper cutting die is connected with three oil cylinders, one of them oil cylinder is positioned in the middle of cutting die 5, two other oil cylinder distributes along intermediate symmetry, the oil cylinder of ragged edge is 1/2nd of the spacing of two adjacent oil cylinders to the distance of upper cutting die end.Be fixedly installed the lower cutting die 6 matched under upper cutting die, the oil-in of all oil cylinders is all positioned at the same valve chamber of reversal valve, and oil-out is all connected in the same valve chamber of reversal valve, ensures the synchronous and pressure uniform of hydraulic jack action like this.The utility model, except may be used for sheet metal bending, after upper cutting die and lower cutting die match corresponding mould, can use by mold pressing workpiece, and possesses the function of forcing press simultaneously.
After detailed description embodiment of the present utility model, the personage being familiar with this technology can be well understood to, do not departing under above-mentioned claim and spirit and can carry out various change and amendment, all above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all belong to the scope of technical solutions of the utility model, and the utility model is not also limited to the embodiment of example in description.
