Description
Technical Field
The invention relates to the technical field of bending equipment, in particular to a novel rotary lug type hinge die.
Background
At present, in the bending machine die industry, the application of the hinge die is very wide. When a common die is bent, the bending operation cannot be performed under the condition that the opening is small and the interior of the common die needs to be bent when the four-side semi-closed product is produced. Because the fixed appearance of the common mould determines that the common mould can only be used for open type bending, when the semi-closed bending and combined type bending are needed, the common mould can not be used. In this case, the hinge mold is produced at the same time. The hinge mold can be used for greatly unfolding a user under the condition that part of the hinge mold is not suitable for the common mold due to the advantage of adjustable length, so that the industrial problem is solved.
The defects and shortcomings of the hinge die in the prior art (please refer to fig. 6-7) are as follows:
1. the current hinge die is not perfect in design, and has a plurality of small problems in practical use. Two movable moulds are flagging naturally under the circumstances that does not receive the power, during operation, the pressure sword of movable mould and the surface contact of work piece just can make two movable moulds move to operating position (namely the pressure sword of movable mould aligns with the pressure sword of hinge mould main part), before bending, such design makes the pressure sword of movable mould and work piece surface produce the friction, because the roughness and the roughness on work piece material and surface are different, the coefficient of friction that produces is different, when two movable moulds of left and right sides are different to the frictional force that the work piece applyed, probably will make the work piece produce and shift from left to right, the work piece shifts the back, it just can lead to the work piece to scrap to bend again.
2. When the die is in the die withdrawing state, the total height of the die is higher than the working state, friction resistance is generated on the surface of a workpiece for reducing the pressing edge of the movable die, the falling speed of a lifting mechanism of the bending machine is needed, the lifting is slow, and therefore the working efficiency is not high greatly.
3. The friction frequency generated between the pressing edge of the movable die and the surface of the workpiece is higher, so that the service life of the die is short.
4. The existing common hinge mold has high production and manufacturing cost, complex process and troublesome combination and assembly.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 5, the present invention provides a technical solution: a novel rotary lug type hinge die comprises a hinge die main body 1 and rotary movable dies 2 on two sides, wherein a main body pressing die 11 extends from the lower end of the middle part of the hinge die main body 1, a main body pressing blade 12 is arranged on the bottom edge of the main body pressing die 11, the rotary movable dies 2 are rotatably mounted at two ends of the hinge die main body 1 through positioning pin shafts 7, lug dies 21 extend from the bottom of the outer sides of the rotary movable dies 2, auxiliary pressing blades 22 for horizontally aligning with the main body pressing blade 12 are arranged on the bottom edge of the rotary movable dies 2, and the weight size of the rotary movable die 2 positioned on the inner side of each positioning pin shaft 7 is larger than that of the rotary movable die 2 positioned on the outer side of each positioning pin shaft; when the main body pressing blade 12 and the auxiliary pressing blade 22 are horizontally aligned, the top of the rotary movable die 2 is abutted against the end of the hinge die main body 1, and movable groove cavities 13 for the inward rotation of the rotary movable die 2 are formed in the two sides of the hinge die main body 1.
Because the weight size of the rotary movable die 2 positioned on the inner side of the positioning pin shaft 7 is larger than the weight size of the rotary movable die 2 positioned on the outer side of the positioning pin shaft 7, the rotary movable die 2 has a tendency of rotating outwards around the positioning pin shaft 7, when the main body pressing edge 12 and the auxiliary pressing edge 22 are horizontally aligned, the top of the rotary movable die 2 is abutted against the end part of the hinge die main body 1, the hinge die main body 1 limits the rotary movable die 2 to rotate outwards continuously, so that the main body pressing edge 12 of the hinge die main body 1 and the auxiliary pressing edge 22 of the rotary movable die 2 are horizontally aligned, namely, the main body pressing edge 12 and the auxiliary pressing edge 22 are positioned on the same straight line under a natural state and a working state, when the lifting mechanism of the bending machine drives the rotary lug type hinge die to press and bend a workpiece, the main body pressing edge 12 and the auxiliary pressing edge 22 are simultaneously contacted with the surface of the workpiece, therefore, the left and right displacement of the workpiece in the pressing process is effectively avoided, effectively reduce the disability rate of bending, the stability of work piece product is strengthened.
The hinge die comprises a hinge die main body 1, a connecting plate 4 is fixedly connected to the rear end face of the hinge die main body 1 through a plurality of assembling bolts 3, and rotary movable dies 2 are rotatably mounted at two ends of the connecting plate 4 through positioning pin shafts 7. The hinge module is formed by assembling a hinge module main body 1, a connecting plate 4, a positioning pin shaft 7 and a rotary movable module 2, and has the advantages of simple structure, lower manufacturing cost and convenient combination and assembly.
The movable groove cavity 13 is provided with an arc side wall 131 and an inclined side wall 132, the arc center of the arc side wall 131 is located on the central axis of the positioning pin 7, the inner side end of the rotary movable die 2 is provided with a movable die inclined side wall 23 for fitting with the inclined side wall 132, an arc transition portion is adopted between the bottom of the movable die inclined side wall 23 and the end of the auxiliary pressing edge 22, and the arc transition portion is in sliding fit with the arc side wall.
Due to the structural arrangement, the rotary movable die 2 can flexibly rotate inwards, the main body pressing blade 12 and the auxiliary pressing blade 22 can be perfectly aligned in a natural state, and a good bending effect can be achieved during working.
The top of rotatory movable mould 2 is passed through connecting bolt 6 fixed mounting and is had horizontal stopper 5, the horizontal spacing groove 14 that is used for conflicting with horizontal stopper 5 cooperation is seted up at the both ends of hinge mould main part 1. The horizontal width of the horizontal limiting block 5 is smaller than the distance between the central axis of the positioning pin shaft 7 and the outer side wall of the rotary movable die 2. When the main body pressing edge 12 and the auxiliary pressing edge 22 are horizontally aligned, the horizontal limiting block 5 is embedded into the horizontal limiting groove 14, the horizontal limiting groove 14 can limit the trend that the rotary movable die 2 continues to rotate outwards, and the main body pressing edge 12 and the auxiliary pressing edge 22 are horizontally aligned in a natural state (or a working state).
The sections of the main body pressing edge 12 and the auxiliary pressing edge 22 are right-angled.
