Abstract
The utility model provides an upper die of a bending machine, which comprises an upper die body, wherein the upper section of the upper die body is provided with an upper die bayonet, the lower section of the upper die body is provided with an upper die pressure head, the upper die bayonet is a rectangular groove matched with the bending machine, the lower edge of the rectangular groove is outwards extended and provided with a boss, and a rectangular avoiding cavity is arranged in the middle of the upper die body below the boss. The utility model has simple structure, low manufacturing cost and convenient installation, and the rectangular avoiding cavity is arranged in the middle of the upper die body, thereby not only avoiding the interference of parts during bending, but also lightening the weight of the upper die and ensuring that the upper die is more labor-saving to disassemble and replace; four angles in the rectangular avoidance cavity position in the middle of the upper die body are in arc transition, so that cracking caused by stress concentration can be prevented, and meanwhile, the strength is ensured.
Description
Technical Field
The utility model relates to the technical field of bending dies, in particular to an upper die of a bending machine.
Background
The bending machine is equipment capable of processing metal plates, and mainly structurally comprises a machine tool support, a hydraulic driving device, an upper die fixing support, an upper die, a workbench, a lower die fixing support and the like. The machine tool completes the processing of the parts by the upper die and the lower die in an extrusion forming mode through a hydraulic driving device.
The upper die and the lower die for the bending machine are of detachable structures, and the matched upper die and the matched lower die are replaced according to the size and the appearance requirements of different parts. However, the existing bending machine is limited by the structural limitations of the upper die and the lower die, and can only bend parts with simple structures. For some special-structure C-shaped parts, because 4 continuous 90-degree bends exist, the parts can interfere with an upper die during bending, and the parts cannot be bent.
Disclosure of Invention
In order to solve the problem that the existing bending machine cannot bend C-shaped parts with special structures, the utility model provides an upper die of the bending machine, which has the characteristics of simple structure, convenience in manufacturing and low cost.
Therefore, the technical scheme of the utility model is as follows: the utility model provides an upper die of bender, includes the last die body, and the upper segment of going up the die body is equipped with last mould bayonet socket, hypomere and is equipped with mould pressure head, its characterized in that: the upper die bayonet is a rectangular groove matched with the bending machine, a boss extends outwards from the lower edge of the rectangular groove, and an avoiding cavity is formed in the middle of an upper die body below the boss.
The technical scheme is further improved as follows: the avoidance cavity is a rectangular cavity, and four corners of the rectangle are in arc transition; and the arc transition is adopted, so that the cracking caused by stress concentration can be prevented, and the strength is ensured at the same time.
The technical scheme is further improved as follows: the width between the bottom surface of the boss and the upper die body is gradually decreased, so that the supporting strength of the boss is ensured.
The technical scheme is further improved as follows: the upper die pressing head is of a conical structure matched with the bending angle, and the end part of the upper die pressing head is in symmetrical convex arc transition through the middle part of the upper die pressing head, so that the bending effect is ensured.
Has the advantages that: compared with the prior art, the utility model has the following advantages:
1. the upper section of the upper die body is provided with a rectangular groove matched with the mounting position of the bending machine, so that the upper die body is convenient to dismount and mount and high in universality;
2. the rectangular avoiding cavity is arranged in the middle of the upper die body, so that interference of parts during bending can be avoided, the weight of the upper die is reduced, and the upper die is more labor-saving to disassemble and replace; four corners of a rectangular avoidance cavity in the middle of the upper die body are in arc transition, so that cracking caused by stress concentration can be prevented, and meanwhile, the strength is ensured;
3. the upper die is simple in structure, easy to manufacture and low in manufacturing cost.

Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings, but the embodiment should not be construed as limiting the present invention.
The utility model is shown in fig. 1 to 5:
the utility model provides an upper die of bender, includes upper die body H, and the upper segment of upper die body is equipped with the mould bayonet socket, the hypomere is equipped with mould pressure head 1, go up the mould bayonet socket and be the rectangular channel 2 that suits with the bender, the lower edge of rectangular channel is outwards extended and is equipped with boss 3, is equipped with in the middle of the upper die body of boss below and dodges cavity 4. An avoiding cavity is arranged in the middle of the upper die body, so that interference of a part (such as a part D in the figure 4) during bending can be avoided, the weight of the upper die is reduced, and the upper die is more labor-saving to disassemble and replace;
the avoidance cavity is a rectangular cavity, and four corners of the rectangle are in transition by adopting circular arcs 41; and the arc transition is adopted, so that the cracking caused by stress concentration can be prevented, and the strength is ensured at the same time.
The width A between the bottom surface of the boss 3 and the upper die body is gradually reduced so as to increase the strength of the boss.
The upper die pressing head 1 is in a conical structure 11 which is adaptive to the bending angle, and the end part of the upper die pressing head is in transition through a convex arc 12 which is symmetrical in the middle.
Those skilled in the art will appreciate that the details of the present invention are not described in detail herein.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
