Description

Arc bending die

Technical Field

The utility model relates to a mechanical die field, concretely relates to circular arc mould of bending.

Background

In the production and processing of sheet metal products, bending processing of a part of circular arcs requiring specific radius can occur. The conventional bending die cannot directly bend the circular arc, and can only simulate the circular arc effect through continuous and repeated bending. Therefore, the appearance is not beautiful, the production efficiency is greatly lagged behind, and the production time and the production cost of enterprises are greatly influenced.

Another method for processing the arc bending is to make a simple die with the same angle radius to process the bending according to the processing angle and the processing radius of the product. Due to different textures and materials of the materials, the material is easy to bend in place or to rebound during bending in one-step forming, and the precision requirement of actual production cannot be met.

Therefore, design a general novel circular arc mould of bending that can guarantee precision and efficiency of bending, be the inevitable demand of panel beating processing enterprise.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a circular arc mould of bending for solve the panel beating circular arc among the prior art and bend the problem that machining efficiency is low and the precision is poor.

The utility model provides a circular arc mould of bending, including moulding-die one and moulding-die two, moulding-die one is including bending last mould one and the lower mould one of bending, moulding-die two is including bending last mould two and the lower mould two of bending, the contact surface cooperation of bending last mould one and the lower mould one of bending sets up to wave structure, bend two bottoms of last mould and set up to the semicircle arc structure, bend two upper ends of lower mould and set up the cooperation and bend the semicircle arc recess of last mould two semicircle arc structures.

Further, the first bending upper die and the second bending upper die are fixedly installed in an upper die cavity of the bending machine, and the first bending lower die and the second bending lower die are fixedly installed in a lower die cavity of the bending machine.

Furthermore, the middle part of the second bending upper die is of a conical structure.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.

As shown in FIG. 1, the utility model provides a circular arc mould of bending, including moulding-die one and moulding-die two, moulding-die one is including bending mould one 1 and the lower mould one 2 of bending, moulding-die two is including bending mould two 3 and the lower mould two 4 of bending, the contact surface cooperation of bending mould one 1 and the lower mould one 2 of bending sets up to the wave structure, bend and go up mould two 3 bottoms and set up to the semicircle structure, bend two 4 upper ends of lower mould and set up the cooperation and bend the semicircle recess of mould two 3 semicircle structures. In the embodiment, the workpiece is firstly bent into a wave-shaped structure through the pressing die, the contact surface between the material and the die is larger, the stress is more uniform, the coefficient of resilience of the workpiece is smaller, and the processing deviation is better controlled; and then the wavy workpiece is bent into a semi-circular arc structure with a required specific radius by a pressing die, so that the bending effect is good, the bending is not easy to rebound, and the reject ratio is low.

The first bending upper die 1 and the second bending upper die 3 are fixedly arranged in an upper die cavity 5 of the bending machine through bolts, the first bending lower die 2 and the second bending lower die 4 are fixedly arranged in a lower die cavity 6 of the bending machine through bolts, wherein, the upper die cavity 5 of the bending machine drives the first bending upper die 1 and the second bending upper die 3 to move up and down through an external driving mechanism, the first pressing die and the second pressing die are in an open state, at the moment, the workpiece is conveyed between the first bending upper die 1 and the first bending lower die 2 and between the second bending upper die 3 and the second bending lower die 4, and then, the first bending upper die 1 and the second bending upper die 3 are pressed down to bend the workpiece, the limit of the first pressing die and the limit of the second pressing die are adjusted to be consistent, and when the bending is pressed down, the descending distances of the first bending upper die 1 and the second bending upper die 3 are the same, so that the two sets of dies can work simultaneously during each bending, and the working efficiency is improved.

Specifically, the middle part of the second bending upper die 3 is of a conical structure.

In conclusion, the utility model discloses set up moulding-die one and moulding-die two, the work piece is bent into the wave structure through the moulding-die at first, and the material is bigger with the contact surface of mould, and the atress is more even, so the coefficient of resilience of work piece is littleer, and the processing deviation is also better controlled; and then the wavy workpiece is bent into a semi-circular arc structure with a required specific radius by a pressing die, the bending effect is stable, and the reject ratio is low, so that the workload of subsequent shaping procedures is reduced, and the working efficiency is improved.
