Abstract
The utility model relates to the technical field of bending dies, in particular to an arc sheet bending die. The arc sheet bending die structurally comprises a male die and a female die with a cavity. An arc forming cavity is formed at the bottom of the cavity. Slide grooves with opposite openings are formed at two ends of the forming cavity respectively. The distance between the bottoms of the two slide grooves is larger than the arc length of an arc sheet. The height of the opening of each of the two slide groove is larger than the thickness of the arc sheet. By the arc sheet bending die, deviation, curving and deformation, before formation, of the arc sheet in the cavity can be avoided.
Description
Technical field
The utility model relates to the bending die technical field, particularly a kind of arc sheet material bending die for the bending metals sheet material.
Background technology
For the metal sheet that the metal sheet on plane need be bent to arc, technological means commonly used is with bending die pressing brake forming.
Bending die comprises die and punch in the prior art, and die offers die cavity, and the bottom of this die cavity is provided with the forming cavity of arc.The concrete forming process of arc sheet material is, at first the metal sheet with the plane is placed into groove, is pressure bonded to the groove of die again by punch, and the metal sheet on plane bends to required curved metal sheet material the most at last.
There is following problem in the prior art, because the curved metal sheet material is the metal sheet on plane before moulding, and the projected length of the metal sheet on plane is greater than the projected length of curved metal sheet material, therefore, directly the metal sheet on the plane before the moulding is put into the process of die cavity, at first be to occur off normal easily, secondly be since the temperature of bending die than higher, the metal sheet on plane causes distortion owing to rolling after being placed into die cavity easily.
The utility model content
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and provides a kind of and be positioned over die cavity for crooked arc sheet material before moulding and can not occur biased, crooked and roll the arc sheet material bending die of distortion.
The purpose of this utility model is achieved through the following technical solutions:
A kind of arc sheet material bending die is provided, comprise punch and the die that offers die cavity, the bottom of described die cavity is provided with the forming cavity of arc, the two ends of described forming cavity offer notch respectively and are the chute that is oppositely arranged, distance between the bottom land of described two chutes is greater than the length of arc sheet material arc length, and the notch height of described two chutes is greater than the thickness of arc sheet material.
Wherein, described chute is the rectangle chute.
Wherein, the distance between the bottom land of described two chutes is than the big 1～2mm of length of arc sheet material arc length.
Wherein, the big 0.5～1mm of thickness of the notch aspect ratio arc sheet material of described two chutes.
The beneficial effects of the utility model: a kind of arc sheet material bending die, the two ends of described forming cavity offer notch respectively and are the chute that is oppositely arranged, distance between the bottom land of described two chutes is greater than the length of arc sheet material arc length, and the notch height of described two chutes is greater than the thickness of arc sheet material.In the utility model, the concrete forming process of arc sheet material is that the sheet material with the plane slips into described die from the side of an end of described die along chute, described two chutes can form positioning action to the arc sheet material before the moulding, the situation that off normal can not occur, simultaneously, the metal sheet on plane bending can not occur and roll and cause the situation of distortion in placing as the process of die cavity.
Description of drawings
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in the accompanying drawing does not constitute any restriction of the present utility model, for those of ordinary skill in the art, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to the following drawings.
Fig. 1 is the structural representation of moulding rear arc sheet material.
Fig. 2 is the structural representation of a kind of arc sheet material bending die of the present utility model.
In Fig. 1 and Fig. 2, include:
1-arc sheet material, 21-die, 22-punch, 23-die cavity, 24-chute.
The specific embodiment
With the following Examples the utility model is further described.
The specific embodiment of a kind of arc sheet material bending die of the present utility model, as shown in Figure 2, comprise the die 21 and the punch 22 that offer die cavity 23, the bottom of described die cavity 23 is provided with the forming cavity of arc, the two ends of described forming cavity offer the chute 24 that notch is oppositely arranged, distance between the bottom land of described two chutes 24 is greater than the length of arc sheet material 1 arc length, and the notch height of described two chutes 24 is greater than the thickness of arc sheet material 1.
In this specific embodiment, arc sheet material 1 concrete forming process is that the sheet material with the plane slips into described die 21 from the side of an end of described die 21 along chute 24, described two chutes 24 can form positioning action to the arc sheet material 1 before the moulding, simultaneously, the metal sheet on plane bending can not occur and roll the situation of distortion in placing as the process of die cavity 23.
In this specific embodiment, described chute 24 is rectangle chute 24.
In this specific embodiment, distance between the bottom land of described two chutes 24 is greater than the length 1～2mm of arc sheet material 1 arc length, the notch height of described two chutes 24 is greater than the thickness 0.5～1mm of arc sheet material 1, and the sheet material of being convenient to the plane slips into chute 24 from the side of an end of described die 21.
Fig. 1 is the structural representation of moulding rear arc sheet material 1.
Should be noted that at last; above embodiment is only in order to illustrate the technical solution of the utility model; but not to the restriction of the utility model protection domain; although with reference to preferred embodiment the utility model has been done to explain; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from essence and the scope of technical solutions of the utility model.
