Abstract
The invention discloses a bending machine. The bending machine comprises an upper support, a lower support, a lower mold located on the lower support and an upper mold located over the lower mold. Two hydraulic air cylinders are symmetrically arranged on the upper support and are connected through a supporting rod, and the upper mold is connected with the supporting rod; and the lower support and the supporting rod are provided with a first sensor and a second sensor respectively. Only one set of molds is required to be adopted, and the bending machine can adapt to multiple bending specifications, the phenomenon that in the production process, the molds are frequently replaced is avoided, the production continuity is effectively improved, and the production efficiency is improved.
Description
Technical field
The present invention is specifically related to a kind of bender.
Background technology
Existing bender adopts hydraulic cylinder to drive mold to press down the sheet metal be placed on bed die usually, complete the bending to sheet metal, but this bending pattern, one set of die can only adapt to a kind of bending specification, in order to reach different bending demands in the middle of actual production, and more mold exchange of having to frequently, not only waste time and energy, have impact on the efficiency of production, and the purchase of the mould of a large amount of different sizes, too increase the input of cost.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, provide a kind of just can the bender of the multiple bending specification of simultaneous adaptation without the need to frequent more mold exchange.
Technical scheme: for achieving the above object, the invention provides a kind of bender, comprise upper bracket, lower carriage, the mold that is positioned at the bed die above lower carriage and is positioned at directly over bed die, described upper bracket is symmetrically arranged with two hydraulic cylinders, described two hydraulic cylinders are interconnected by support bar, described mold is connected to support bar, and described lower carriage and support bar are respectively equipped with first sensor and the second sensor.
Further, described bed die comprises base, is positioned at two rollers on base and two iron blocks with roller integrated molding.
Further, described lower carriage is provided with two tight fixed bolts, and described tight fixed bolt runs through lower carriage, base, roller and iron block.
Preferably, the angle of described support bar and hydraulic cylinder is 90 degree, this ensure that mold is perpendicular to sheet metal when carrying out bending to sheet metal, optimizes the effect of bending.
Preferably, described first sensor and the second sensor are all connected to control display screen.
Design principle of the present invention is: first sensor and the second sensor can induce relative distance between them and real time data transmission be presented at and control on display screen, the distance pressed down needed for sheet metal can calculate the minimum of a value of the relative distance of first sensor and the second sensor, by being the numerical value that mold presses down end in the minimum of a value controlling display screen sets this relative distance, required bending specification can be obtained, like this by controlling the setting of the relative distance minimum of a value of first sensor and the second sensor on display screen, multiple bending specification can be adapted to, and the setting of bed die upper roller can change the opening amplitude of bed die, more enrich the diversified demand of bending.
Beneficial effect: compared with prior art, only one group of mould need be adopted just to adapt to multiple bending specification, avoid regular more mold exchange in process of production, the continuity of production obtains effective reinforcement, and production efficiency have also been obtained lifting in the present invention.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
As shown in Figure 1, the invention provides a kind of bender, comprise upper bracket 1, lower carriage 2, the mold 4 that is positioned at the bed die 3 above lower carriage 2 and is positioned at directly over bed die 3, described upper bracket 1 is symmetrically arranged with two hydraulic cylinders 5, described two hydraulic cylinders 5 are interconnected by support bar 6, described mold 4 is connected to support bar 6, and described lower carriage 2 and support bar 6 are respectively equipped with first sensor 7 and the second sensor 8.
In the present invention, bed die 3 comprises base 31, be positioned at two rollers 32 on base 31 and two iron blocks 33 with roller 32 integrated molding, before bending operation starts, unclamp tight fixed bolt 21 adjusts the opening that two iron blocks 33 are formed size by rotation roller 32, the size of opening directly determines the size of the radian of bending, tighten up tight fixed bolt 21, make base 31, roller 32 and iron block 33 keep fixing, then according to the specification requirement of bending, the minimum of a value of first sensor 7 and the second sensor 8 relative distance is set at control display screen 9, to treat that the sheet metal of bending is positioned on bed die 3, primer fluid air cylinder 5 on control display screen 9, hydraulic cylinder 5 does and moves back and forth up and down, mold 4 pairs of sheet metals are driven to carry out bending, as needed when the bending of different size requires, only again need adjust the openings of sizes of bed die 3 and set the minimum of a value of corresponding first sensor 7 and the second sensor 8 relative distance.
