It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the present invention.
It is to be understood that the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, like reference numerals refer to like elements throughout.
Referring to fig. 1 to 9 in combination, the present embodiment discloses a composite trimming structure for straight trimming and oblique trimming, including:
the main cutter block 1 is provided with a straight trimming lower cutting edge 11 and an inclined trimming lower cutting edge 12, and the straight trimming lower cutting edge 11 is adjacent to the inclined trimming lower cutting edge 12;
the upper pressing piece 5 is used for pressing the plate on the lower main cutter block 1;
the upper straight trimming insert 4 is arranged beside the upper blanking part 5, the upper straight trimming insert 4 is provided with a straight trimming upper cutting edge 41, and the straight trimming upper cutting edge 41 corresponds to the straight trimming lower cutting edge 11, so that the upper straight trimming insert 4 is trimmed straight by descending; and
the upper inclined trimming insert 3 is provided with an inclined trimming upper cutting edge 31, and the inclined trimming upper cutting edge 31 corresponds to the inclined trimming lower cutting edge 12, so that the upper inclined trimming insert 3 is obliquely trimmed by moving towards the lower main cutter block 1;
the composite trimming structure further comprises a lower waste material cutter block 2, a waste material cutting lower cutting edge 21 is arranged on the lower waste material cutter block 2, a waste material cutting upper cutting edge 42 is further arranged on the upper straight trimming insert 4, the waste material cutting upper cutting edge 42 is adjacent to one end, close to an inclined trimming position, of the straight trimming upper cutting edge 41, when the upper straight trimming insert 4 moves downwards, the waste material cutting lower cutting edge 21 and the waste material cutting upper cutting edge 42 are matched with a waste material area B for cutting a plate material, and when the upper inclined trimming insert 3 is obliquely inserted, the upper inclined trimming 3 is located above the lower waste material cutter block 2.
In practical implementation, the trimming structure of the above and following embodiments all belong to a part of a trimming die, and the trimming die includes an upper die and a lower die, the lower main cutter block 1 and the lower scrap cutter block 2 are disposed on the lower die, the upper pressing member 5, the upper straight trimming insert 4 and the upper inclined trimming insert 3 are disposed on the upper die, and the upper die is provided with an inclined wedge (not shown, this structure is an existing structure, and details thereof are not described here) for guiding the upper straight trimming insert 4.
When the composite trimming structure is used for trimming, a lower main cutter block 1, a lower waste cutter block 2 and a lower die are all in static states, the upper die is a movable die and moves downwards to drive an upper straight trimming insert 4 and an upper inclined trimming insert 3 to move downwards, the straight trimming upper cutting edge 41 is inserted into a plate material before the inclined trimming upper cutting edge 31, namely the straight trimming is completed before the inclined trimming, because the lower die is provided with the lower waste cutter block 2 and the upper straight trimming insert 4 is additionally provided with a waste material cutting upper cutting edge 42, the upper main cutter block 1 is subjected to straight trimming and waste material cutting in the descending process to divide a waste material area B into two parts, one part of waste material falls off (an area B1 in figure 9), then the upper inclined trimming insert 3 is inserted into the plate material for inclined trimming, the other part of waste material falls off while the inclined trimming (an area B2 in figure 9), and the trimming structure enables the waste material to be divided into two parts, during trimming, an included angle corresponding to the straight trimming and the oblique trimming cannot be formed on the waste material, the waste material is separated in the straight trimming process before the included angle is formed, and the waste material is separated in the oblique trimming process at the other part, so that the situation that the waste material is clamped on the die is avoided, the trimming reliability is improved, and the continuous work of the die is facilitated. Of course, in the actual implementation process, the oblique trimming can be performed before the straight trimming by adjusting the feeding amount or the structure of the upper-type oblique trimming insert 3 and the upper-type straight trimming insert 4, even the oblique trimming and the straight trimming can be performed simultaneously, and the waste material can be divided into two parts regardless of the sequence.
In some embodiments, the lower waste cutter block 2 is provided with an avoiding structure for avoiding the upper inclined trimming insert 3.
Specifically, in some embodiments, the scrap cutting lower edge 21 includes an upper edge section 213, a transition edge section 212, and a lower edge section 211, which are sequentially disposed, wherein the height position of the upper edge section 213 is higher than that of the lower edge section 211, the lower edge section 211 is closer to the straight trimming lower edge 11, and the positions of the lower edge section 211 are lower than those of the straight trimming lower edge 11.
During trimming, in order to ensure reliable trimming, both straight trimming and oblique trimming generally have an excessive cutting amount, the positions of all the positions of the low-position edge section 211 are lower than the position of the straight trimming lower edge 11, so that the space between the low-position edge section 211 and the end point of the straight trimming lower edge 11 becomes an excessive cutting avoiding space of the upper oblique trimming insert 3 during oblique trimming, and the avoiding space can avoid the oblique trimming insert and also has the function of avoiding parts.
In some embodiments, the inclined trimming overcut amount corresponding to the endpoint of the lower edge 11 adjacent to the straight trimming edge when the inclined trimming upper edge 31 is subjected to inclined trimming is X; the height difference between the end point of the lower blade section 211 close to the straight trimming lower edge 11 and the end point of the straight trimming lower edge 11 close to the lower blade section 211 is Y; the downward feeding amount of the straight trimming upper cutting edge 41 is Z; y is larger than X + the thickness of the part plate, Z is larger than Y + m, wherein m is larger than or equal to 1 mm. For example, when the thickness of the sheet is less than 2mm, such as when trimming a sheet with a thickness of 0.8mm or 1.2mm, the value of X may be 2mm, the value of Y may be 4mm, and the value of Z may be 6mm, although the value of X, Y, Z is not limited thereto.
In some embodiments, the scrap cutting lower edge 21 is rounded throughout.
The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
