Abstract
This utility model relates to the apparatus for bending of a kind of interior bending workpieces, including upper die and lower die, board, described board has been rotatably connected two symmetrical lower molds by rotating shaft, it is fixedly connected with return spring by rivet in described lower mold, the other end of described return spring is fixed on board by rivet, and real above described lower mold be furnished with upper mold；This utility model is by arranging return spring and rotating shaft in lower mold, and when upper mold is descending, lower mold is done the center of circle and rotated, the one-shot forming in the groove of lower mold of interior bending workpieces, when upper mold is up, under the elastic force effect of return spring, lower mold is resetted, time saving and energy saving, simple and practical.
Description
Technical field
This utility model relates to Machining Technology field, particularly relates to the apparatus for bending of a kind of interior bending workpieces.
Background technology
For board, bending is requisite machining operations.Bending is that metal blank is on bender
Under the pressure of mould or lower mold, first pass around elastic deformation, subsequently into the course of processing of plastic deformation.And in prior art for
The workpiece of interior bending, bending needs to carry out four steps, complex operation, wastes time and energy.
Based on above reason, the apparatus for bending of a kind of interior bending workpieces is needed to be devised, by arranging in lower mold
Return spring and rotating shaft, when upper mold is descending, lower mold is done the center of circle and is rotated, the one-shot forming in the groove of lower mold of interior bending workpieces,
When upper mold is up, under the elastic force effect of return spring, lower mold is resetted, time saving and energy saving, simple and practical, i.e. a kind of interior bending
The apparatus for bending of workpiece.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that the bending dress of a kind of interior bending workpieces
Put.
This utility model is to be achieved through the following technical solutions:
The apparatus for bending of a kind of interior bending workpieces, including upper die and lower die, board, described board is rotatably connected by rotating shaft
Being connected to two symmetrical lower molds, described lower mold is fixedly connected with return spring by rivet, the other end of described return spring leads to
Crossing rivet to be fixed on board, real above described lower mold be furnished with upper mold.
Further, the lower shape of described upper mold matches with lower mold interior grooves shape, when upper mold is descending, and lower mold
Do the center of circle to rotate, the one-shot forming in the groove of lower mold of interior bending workpieces.
Further, time in working order, it is matched in clearance in the bottom of described upper mold and lower mold interior grooves, the most right
Workpiece carries out interior bending.
Further, described upper mold is operated by hydraulic gear, stable transmission.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, reasonable in design,
By arranging return spring and rotating shaft in lower mold, when upper mold is descending, lower mold is done the center of circle and is rotated, and interior bending workpieces is in lower mold
One-shot forming in groove, when upper mold is up, under the elastic force effect of return spring, resets lower mold, time saving and energy saving, the most in fact
With.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, upper mold, 2, lower mold, 3, rivet, 4, rotating shaft, 5, return spring, 6, board.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
Referring to Fig. 1, Fig. 1 is structural representation of the present utility model.
The apparatus for bending of a kind of interior bending workpieces, including upper mold 1, lower mold 2, board 6, described board 6 can be turned by rotating shaft 4
Be dynamically connected two symmetrical lower molds 2, and described lower mold 2 is fixedly connected with return spring 5 by rivet 3, described return spring 5
The other end is fixed on board 6 by rivet 3, and real above described lower mold 2 be furnished with upper mold 1；The lower shape of described upper mold 1 with under
Mould 2 interior grooves shape matches；Time in working order, join for gap in the bottom of described upper mold 1 and lower mold 2 interior grooves
Close；Described upper mold 1 is operated by hydraulic gear.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
Protection domain within.
