Technical Field
The utility model relates to a bender mould technical field especially relates to a die-pressing limit mould of bending.
Background
The special product is folded up and down to form a dead edge, the existing conventional bending die can only press one dead edge, and the other dead edge can collide with materials to interfere and cannot be bent.
Two sets of dies for pressing edges of conventional products, and the dies need to be replaced when the process of pressing the edges is completed.
SUMMERY OF THE UTILITY MODEL
Utility model bend the mould purpose provide one set of mould and realize whole product shaping of bending, reduce and change the mould, debug board time guarantees product shaping size precision and work efficiency.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a die for bending edges, its characterized in that, including last mould, activity lower mould, lower mould fixing base, go up the mould and install on the mould clamp on the bender, go up the mould angle of bending and adopt the acute angle, the activity lower mould is installed on the lower mould fixing base, the activity lower mould is equipped with the recess, and the recess top is equipped with the screw thread, the lower mould fixing base also is equipped with the recess, in activity lower mould bottom was embedded into lower mould fixing base recess, reset spring has been placed in the recess of activity lower mould, reset spring one end is supported at activity lower mould recess top, and the other end supports and leans on lower mould fixing base recess bottom, and lower mould fixing base recess other end is equipped with the.
According to the technical scheme, one side of the movable lower die is provided with an inclined edge, the inclined edge is parallel to the inclined edge on one side of the lower die fixing seat, and the distance between the two inclined edges is smaller than the telescopic amount of the reset spring.
According to a further technical scheme, the lower die is provided with an acute-angle bending groove which is consistent with the bending angle of the upper die.
Compared with the prior art, the beneficial effects of the utility model are that:
realize a mould dual-purpose through the cooperation of activity lower mould and lower mould fixing base, specifically be in the activity lower mould recess and lower mould fixing base inslot cooperation have reset spring, reset spring passes through the fixed screw and fixes, activity lower mould one side is equipped with the hypotenuse and is parallel with lower mould fixing base hypotenuse, and the acute angle is pushed out on the work piece through last mould angle of bending and the cooperation of activity lower mould groove of bending to first process during the use, and the second process is through the cooperation of two hypotenuses with the work piece acute angle flattening. And the other side dead edge of the workpiece is not interfered, so that the time for replacing the die is reduced, the working efficiency is improved, and the machining precision is ensured.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
In the figure: 1 go up mould, 2 lower mould fixing bases, 3 activity lower moulds, 4 fixed screws, 5 reset spring, 6 first process acute angle indentation, 7 second process press dead sides, 8 acute angle bending groove, 9 hypotenuses, 10 last mould angles of bending.
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.
Referring to fig. 1, a die for bending a dead edge by pressing comprises an upper die 1, a movable lower die 3 and a lower die fixing seat 2, the upper die 1 is arranged on an upper die clamp of the bending machine, the top structure of the upper die 1 is matched with the upper die clamp of the bending machine, but the bending angle 10 of the upper die is required to be in an acute angle shape, the movable lower die 3 is arranged on the lower die fixing seat 2, the movable lower die 3 is provided with a groove, the top of the groove is provided with a thread, the lower die fixing seat 2 is also provided with a groove, the bottom of the movable lower die 3 is embedded into the groove of the lower die fixing seat 2, a return spring 5 is arranged in the groove of the movable lower die 3, one end of the reset spring 5 is propped against the top of the groove of the movable lower die 3, the other end is propped against the bottom of the groove of the lower die fixing seat 2, the other end of the groove of the lower die fixing seat 2 is provided with a fixing screw 4, and the fixing screw 4 is screwed on the thread of the movable lower die 3.
In this embodiment, activity lower mould 3 one side is equipped with hypotenuse 9, hypotenuse 9 is parallel with hypotenuse 9 of lower mould fixing base 2 one side, and the distance of two hypotenuses 9 is less than reset spring 5's flexible volume guarantees that when its second process died limit 7, the precision on two hypotenuses 9 inseparables guarantees died limits.
In this embodiment, the movable lower die 3 is provided with an acute bending groove 8 consistent with the bending angle 10 of the upper die, so as to ensure an acute indentation 6 in the first process.
To sum up, the utility model provides a mould of bending purpose is that a mould is dual-purpose, realizes a mould dual-purpose through the cooperation of activity lower mould and lower mould fixing base, specifically has reset spring with lower mould fixing base recess fit in the activity lower mould recess, reset spring passes through the fixed screw fixation, activity lower mould one side is equipped with the hypotenuse and is parallel with lower mould fixing base hypotenuse, the first process is through last mould angle of bending and activity lower mould groove cooperation extrusion acute angle on the work piece during use, the second process is through the cooperation of two hypotenuses with the work piece acute angle flatten. And the other side dead edge of the workpiece is not interfered, so that the time for replacing the die is reduced, the working efficiency is improved, and the machining precision is ensured.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
