Abstract
A wavy cutting edge of a thermoforming trimming die belongs to the technical field of plastic forming thermoforming, and a cutting part of the cutting edge is provided with more than one groove, and the interval of each groove is 50 mm; the groove is U-shaped, and the depth of the groove is T +1 mm; and gaps are arranged at the edge positions of two sides of the cutting edge. The utility model discloses the cutting portion of wave blade is wave shape to reduce the service pressure of press, reduce the side cut power, can reach the purpose of cutting off the part in reducing pressure, reduce the loss of board and the harm to the mould.
Description
Technical Field
The utility model belongs to the technical field of the plastic forming thermoforming, especially relate to a thermoforming side cut mould blade.
Background
In the stamping production process of the thermal forming trimming die, when the thermal forming trimming die is long in trimming length or the plate is slightly wavy during trimming, larger force is needed for cutting and trimming the thermal forming cutting die. One of the methods for increasing the pressure is to use a press with a larger pressure value, and after the die is cut off by the cutter, the pressure applied to the die is suddenly increased, and the loss of the machine table due to the increase of the pressure is increased.
Therefore, there is a need in the art for a new solution to solve this problem.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the utility model provides a thermoforming side cut mould wave blade, the cutting portion of wave blade is the wave shape to reduce the service pressure of press, reduce the trimming force, can reach the purpose that cuts off the part when reducing pressure, reduce the loss of board and the harm to the mould.
Thermoforming side cut mould wave blade, characterized by: the cutting part of the cutting edge is provided with more than one groove, and the interval of each groove is 50 mm; the groove is U-shaped, the depth of the groove is T +1mm, and in the formula, T is the thickness of a plate to be cut.
And gaps are arranged at the edge positions of two sides of the cutting edge.
Through the above design scheme, the utility model discloses following beneficial effect can be brought: the utility model provides a thermoforming side cut mould wave blade, the cutting portion of wave blade is the wave shape to reduce the service pressure of press, reduce the trimming force, can reach the purpose that cuts off the part when reducing pressure, reduce the loss of board and the harm to the mould.
The utility model discloses a further beneficial effect lies in: the cutting machine has a simple structure, can achieve the purpose of reducing the loss of the machine without increasing process steps, can reduce about half of trimming pressure, and simultaneously reduces the acting force of the cutting machine table on the die.
Drawings
The invention is further described with reference to the following drawings and detailed description:
figure 1 is the utility model discloses thermoforming side cut mould wave blade structural sketch map.
Fig. 2 is the utility model discloses pressure reaches board effort schematic diagram when thermoforming side cut mould wave blade is cut edge.
In the figure, 1 is a cutting edge, 2 is a groove and 3 is a gap.
Detailed Description
The wavy cutting edge of the thermoforming trimming die is characterized in that as shown in figure 1, more than one groove 2 is formed in the cutting part of the cutting edge 1, and the interval of each groove 2 is 50 mm; the groove 2 is U-shaped, the depth of the groove is T +1mm, and in the formula, T is the thickness of a plate to be cut.
And gaps 3 are arranged at the edge positions of two sides of the cutting edge 1.
Adopt the utility model discloses when thermoforming side cut mould wave blade cuts edge, divide the sheet material into two steps and cut off, as shown in fig. 2, the arrow point direction shows the direction of force, when the side cut length of sheet material is L, the side cut force is 0.5F ~ 0.6F (wherein F is when conventional straight blade, side cut length is the required side cut force of L), in the twinkling of an eye that the sheet material cut off, the pressure of applying on the mould is 0.5F ~ 0.6F, compare with the straight blade that adopts among the conventional prior art, very big reduction side cut force and sheet material back of cutting off, the effort of machine platform to the mould, the damage of machine platform and mould has been reduced, the service life thereof is prolonged.
Claims (2)
