The utility model provides a pressure head of panel bender, the top of pressure head is equipped with a pair of shaping portion, its characterized in that: the shaping portion comprises a first main body and a first auxiliary portion which is arranged at the top of the first main body and extends upwards, the cross section of the first main body is isosceles trapezoid, and the cross section of the first auxiliary portion is rectangular. The cross-section of the shape of first pair of portion is the rectangle, and the top of the vice portion cross-section of second of the cell body of the folding seam that forms promptly is the straight line, and not the point, and stress is more dispersed, has improved the flexibility of folding seam, and the resilience range after the box is folding is less, and the volume reduction range increases.
Description
Technical Field
The utility model relates to a folding technical field, concretely relates to pressure head of panel bender and a collapsible case that is made by this pressure head.
Background
A foldable box is structurally shown in figure 1 and comprises a front side wall 1, a rear side wall 2, a left side wall 3 and a right side wall 4, wherein folding seams 5 are respectively arranged at the adjacent positions of the front side wall 1 and the rear side wall 2 and the left side wall 3 and the right side wall 4 and the middle positions of the left side wall 3 and the right side wall 4, so that the left side wall 3 and the right side wall 4 can be folded towards the inner side of a box body, and the volume of the box body is further reduced. The existing pressure head for pressing and forming the folding seam 5 is shown in figure 2, the top of the pressure head is provided with a pair of forming parts 6 with triangular sections, the formed folding seam 5 is shown in figure 3 and is a pair of groove bodies 7 with triangular sections, and the folding seam 5 of the structure is folded by a box body made of plastic plates such as a honeycomb plate, a hollow plate and the like, the stress on the vertex angle part of the triangle is concentrated, so that the rebound amplitude of the box is large, and the size reduction amplitude is small.
SUMMERY OF THE UTILITY MODEL
In view of the above problem, the utility model provides a pressure head of panel bender, it can solve the technical problem that collapsible case easily kick-backs.
Its technical scheme is such, a pressure head of panel bender, the top of pressure head is equipped with a pair of shaping portion, its characterized in that: the shaping portion comprises a first main body and a first auxiliary portion, wherein the first auxiliary portion is arranged at the top of the first main body and extends upwards, the cross section of the first main body is in an isosceles trapezoid shape, and the cross section of the first auxiliary portion is in a rectangular shape.
Further, the first main body and the first auxiliary part are integrally formed.
Further, the top width of the first main body is equal to the bottom width of the first secondary portion.
The utility model also provides a collapsible case, collapsible case includes preceding lateral wall, back lateral wall, left side wall and right side wall, preceding lateral wall the back lateral wall with the left side lateral wall the position that the right side lateral wall borders on and the left side wall the middle part of right side wall is equipped with the folding seam respectively, the folding seam is formed by the suppression of above-mentioned pressure head.
Further, the folding seam includes a pair of cell bodies, the cell body includes second main part and the vice portion of second that upwards extends from second main part top, the cross-section of second main part is isosceles trapezoid, the cross-section of the vice portion of second is the rectangle.
Further, the top width of the second main body is equal to the bottom width of the second sub-portion.
The utility model discloses a top angle position at the shaping portion of traditional pressure head forms the first subportion that upwards extends, and the cross-section of the shape of first subportion is the rectangle, and the top of the second subportion cross-section of the cell body of folding seam that forms is the straight line, and not the point, and stress is more dispersed, has improved the flexibility of folding seam, and the resilience range after the box folding is less, and the volume reduction range increases; in addition, if the apex angle position of shaping portion cuts and removes and form first subportion, in folding seam shaping earlier stage, not only receive the terminal surface extrusion of first subportion, still receive the extrusion of the both sides wall of first main part, the pressure head resistance is big, and folding seam is difficult for the shaping, and is great to equipment power requirement moreover, and the energy consumption is high, and the utility model discloses upwards extend at the top of shaping portion and form first subportion, in folding seam shaping earlier stage, only receive the terminal surface extrusion of first subportion, the pressure head resistance is little, and folding seam changes the shaping, and is less to equipment power requirement moreover, and the energy consumption is low.
