Trace（It is commonly called as abrading）, product beauty had not only been influenced, but also the scratch easy oxidation corrosion of part surface is caused, influence the quality of product.
Utility model content
Against the above deficiency, the purpose of this utility model is that, a kind of smart structural design, reasonable, effectively reduction are provided
The abrasive no trace bender of product surface.
To achieve the above object, technical solution provided by the utility model is：A kind of no trace bender, including upper
Die holder, upper padding plate, cope plate, lower de- plate, lower bolster, die holder, external stripping plate, outer baffle block, bending tool, bending tool block and rolling
Axis, the upper mold seat, upper padding plate and cope plate to form upper module by being sequentially sequentially stacked from bottom to up, and the outer baffle block is arranged on
One side position of upper mold seat, the external stripping plate are arranged on the position between outer baffle block and cope plate by elastic component；Under described
Die holder, lower bolster and lower de- plate to form lower module by being sequentially sequentially stacked from bottom to up, and the bending tool block is arranged on underlay
One side position of plate, position of the bending tool between lower de- plate and bending tool block simultaneously face the external stripping plate, should
The top of bending tool is used for setting the straight slot of the roller bearing close to the bent angle position of lower de- plate, and the roller bearing is located in the straight slot,
And an outer circumferential surface part for the roller bearing is exposed from the bent angle position of bending tool.
As a kind of improvement of the utility model, the roller bearing is wolfram steel pole.
As a kind of improvement of the utility model, a diameter of 6~8 millimeters of the roller bearing.
The beneficial effects of the utility model are：The utility model smart structural design, rationally in the bent angle position of bending tool
Equipped with rotary roller bearing；During bending, sheet metal component plate is placed on lower de- plate, forcing press starts the upper module downlink of driving,
Cope plate is pressed against on sheet metal component plate, and forcing press continues traveling downwardly, and roller bearing, which is pressurized and starts to roll under frictional force effect, makes metal plate
Golden part plate is more conducive to be bent over, and bending technique is completed when forcing press comes downwards to minimum point, and upper module uplink roller bearing reversely rolls
It is dynamic, it is demoulded convenient for sheet metal component plate, sliding friction is modified to rolling friction, greatly reduces frictional force, entire bending workflow
Journey action is smooth, reliable high, and then efficiently solves common die and the phenomenon that bending scratch easily occur, is wanted particularly with there is surface
The product asked substantially increases yield rate, ensures product quality.
Below in conjunction with the accompanying drawings with embodiment, the utility model is further illustrated.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure diagram of bending tool in the utility model.
Specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of no trace bender provided in this embodiment, including upper mold seat 1, upper padding plate 2, on
Template 3, lower de- plate 4, lower bolster 11, die holder 5, external stripping plate 6, outer baffle block 7, bending tool 8, bending tool block 9 and roller bearing 10, institute
It states upper mold seat 1, upper padding plate 2 and cope plate 3 to form upper module by being sequentially sequentially stacked from bottom to up, the outer baffle block 7 is arranged on
One side position of upper mold seat 1, the external stripping plate 6 are arranged on the position between outer baffle block 7 and cope plate 3 by elastic component；Institute
It states die holder 5, lower bolster 11 and lower de- plate 4 to form lower module by being sequentially sequentially stacked from bottom to up, the bending tool block 9 is set
Put the side position in lower bolster 11, position of the bending tool 8 between lower de- plate 4 and bending tool block 9 simultaneously faces
The external stripping plate 6, the top of the bending tool 8 are used for setting the straight slot 81 of the roller bearing 10, institute close to the bent angle position of lower de- plate 4
It states roller bearing 10 to be located in the straight slot 81, and an outer circumferential surface part for the roller bearing 10 is exposed from the bent angle position of bending tool 8.Roller bearing 10
It can freely be rolled in straight slot 81.The cross-sectional profile profile of bending tool 8 is square.
