In addition, the groove top is established step surface and is matched with load bearing component top evagination, can control the rotation direction of load bearing component.
[description of drawings]
Fig. 1 is the structural representation of seamless bender among the embodiment of the present utility model;
Fig. 2 is the schematic diagram that seamless bender is processed sheet material among the embodiment of the present utility model.
[specific embodiment]
Below in conjunction with accompanying drawing and specific embodiment the technical solution of the utility model is described in detail.
As shown in Figure 1, a kind of seamless bender comprises upper mould piece 10 and the following module 20 of being with groove.Be provided with the load bearing component 200 that two cross sections are circular arc in the groove of following module 20, the inner wall section of groove is an arc, suitable with the shape of cross section of load bearing component 200, the top of two load bearing components 200 is the plane, and is positioned on the same horizontal plane with the end face of following module 20.Upper mould piece 10 is positioned at the top of two load bearing component 200 junctions.This load bearing component 200 is used for carrying sheet material 30, and sheet material 30 develops with the plane on load bearing component 200 tops.Wherein, upper mould piece 10 is spininess or taper, aims at the junction of two load bearing components 200 sheet material 30 is exerted pressure.When upper mould piece 10 moves down when sheet material 30 exerted pressure, pressure spot is between two load bearing components 200, sheet material 30 is to the groove inner bending, upper mould piece 10 continues to exert pressure downwards, pressure forces two load bearing components, 200 inside backward rotation, and the plane on the top of load bearing component 200 and sheet material are fitted and rotated.Increased the contact area of sheet material 30 like this, reduced pressure, can on sheet material, not produce folding line with load bearing component 200.
In the present embodiment, the cross section semicircular in shape of two load bearing components 200 can be smaller part circle or large semi-circular, and next-door neighbour's setting, and the plane on the top of two load bearing components 200 is on same plane.When the cross section of load bearing component 200 is large semi-circular, be formed with the slit between the plane on two tops, the slit 10 pairs of sheet materials 30 of upper mould piece of being more convenient for are exerted pressure sheet material 30 are bent in the slit, and load bearing component 200 cross sections when being large semicircle its center of gravity higher, easier rotating.When the cross section of load bearing component 200 is smaller part when circular, the slit suitable with upper mould piece 10 can be set in the junction of two load bearing components 200, so that aiming at slits, upper mould piece 10 downwards sheet material 30 is exerted pressure.The radius of two load bearing components 200 can be equally big, two load bearing components 200 stressed more even.Certainly radius also can be different big, guarantees that the plane on the top of two load bearing components 200 gets final product on same plane.
In the present embodiment, the groove top is provided with step surface (not indicating among the figure), and protrude in the outside, load bearing component 200 tops, can ride on this step surface, has limited the rotation direction of load bearing component 200, and promptly two load bearing components 200 are only inwardly to rotate in opposite directions.In addition, be bent to form hook downwards behind the evagination of the outside, load bearing component 200 tops, corresponding step surface is arranged to the inclination shape suitable with this hook, by easier being stuck on the step surface of hook, and the rotation direction of control load bearing component 200.
As illustrated in fig. 1 and 2, above-mentioned seamless bender in the process that sheet material is processed is: sheet material 30 is placed on the following module 20, and the sheet material 30 and the plane on interior load bearing component 200 tops that are provided with of groove are developed, upper mould piece 10 moves down exerts pressure to sheet material 30, when sheet material 30 and load bearing component 200 are stressed, the sheet material 30 slit inner bendings of meeting between load bearing component 200, force two load bearing components 200 inwardly to rotate simultaneously, make the top of load bearing component 200 and partial sidewall protrude groove around the center of circle separately.The plane, top of load bearing component 200 keeps fitting with the sheet material 30 that is bent in rotating process always, has increased the lifting surface area of mould to sheet material 30 like this, can not produce folding line on sheet material 30.
In addition, load bearing component 200 can be three, four or other quantity, and the arc quantity of corresponding grooves also is provided with the number of corresponding load bearing component 200.
Above-mentioned seamless bender, in the groove of module the load bearing component that two cross sections are circular arc is set under adopting, the shape of the shape of groove and two load bearing components is suitable, guaranteed to rotate when load bearing component is stressed, the plane on the top of load bearing component at grade, make the plane on sheet material and load bearing component top fit, guaranteed sheet material is added man-hour, the plane on the top of sheet material and load bearing component fits together always, increased the contact area of sheet material and load bearing component, reduce pressure, can on sheet material, not produce folding line.
In addition, step surface is established on the groove top, matches with the side top evagination of load bearing component, can control the rotation direction of load bearing component.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
