Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The first embodiment is as follows:

referring to fig. 1, the pneumatic flattening die for the bending machine comprises a die body 1, wherein the die body 1 comprises an upper die 11 and a lower die 12, the upper die 11 is connected with the lower die 12, a bending groove 2 is formed in the top surface of the upper die 11 along the length direction, the bending groove 2 is matched with a blade of the bending machine, a material is placed on and covers the surface of the bending groove 2, the material is descended by the blade and bends at the bending groove 2 along with the blade, a flattening gap is formed between the upper die 11 and the lower die 12, the bent part of the material is taken out and placed into the gap, and the bent part is flattened by descending of the upper die 11 and the lower die 12.

The second embodiment:

referring to fig. 2, a difference between the first embodiment and the second embodiment lies in that the upper mold 11 and the lower mold 12 are detachably connected, wherein a T-shaped insert block is disposed at the bottom of the upper mold 11, a T-shaped slot is disposed at the top of the lower mold 12, the upper mold 11 and the lower mold 12 are connected together in a manner that the insert block and the slot are inserted into each other, and when one of the two molds is damaged by connection during separation, local replacement is facilitated, and overall replacement is avoided, thereby reducing the replacement cost of the apparatus.

Example three:

referring to fig. 3, the difference between the second embodiment and the first embodiment is that the upper mold 11 and the lower mold 12 are connected by fixing, wherein the fixing includes integral molding, welding, and the like. The strength of the whole equipment is improved in a fixed mode.

Example four:

referring to fig. 4-7, this embodiment is different from the first embodiment in that a guide bar 121 is disposed on a side surface of a lower die 12, symmetrical spring holes are disposed at a bottom end of the lower die 12, the lower die 12 is inserted into a base of a bending machine, a spring in the base is inserted into the spring hole, the guide bar 121 is inserted into a guide groove of the base, the lower die 12 is guided in a descending process through the arrangement of the guide bar 121 and the guide groove, a movement track does not deviate, and a spring structure is matched with the spring structure, the spring is compressed and deformed in a descending process of the lower die 12, the base of the bending machine is located in a gap of a flat shape, the upper die 11 slowly descends, the gap gradually decreases until the upper die 11 contacts the base, so that a bent material is placed on the base, and the portion of the bending groove 2 is flattened by pressure when the upper die 11 descends.
