DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] See also Figures 1 to 3, this embodiment provides a pressing die for producing a spiral plate of a spiral granulator, comprising: a lower half die 1 arranged on the lower workbench of a press machine, and an upper half die 2 arranged on the upper workbench of the press machine; the lower half die 1 comprises: a first base 3 that can be fixed on the lower workbench, a first arc-shaped plate 4 arranged on the first base 3, and a pressure-bearing die arranged on the outer side of the first arc-shaped plate 4 and fixedly connected to the lower workbench; the pressure-bearing die is in the shape of an arc as a whole, and the upper bottom surface of the pressure-bearing die is a first spiral inclined surface; the upper half die 2 comprises: a second base 5 that can be fixed under the upper workbench, and a pressing die arranged on the second base 5, the pressing die is in the shape of an arc as a whole, and the lower bottom surface of the pressing die is a second inclined surface with the same parameters as the first inclined surface. The outer diameter of the first arc plate is the same as the inner diameter of the spiral plate. The cut plate is placed on the first inclined surface, and the press machine drives the upper half die 2 downward to press the plate under the action of the first inclined surface and the second inclined surface.

[0018] A first baffle 6 is provided at the lower end of the first inclined surface, a second baffle 7 is provided on the outer side of the lower end of the first inclined surface, and a third baffle 8 is provided on the outer side of the upper end of the first inclined surface. The first baffle 6, the second baffle 7, and the third baffle 8 are used to constrain the position of the plate so that the plate is always located between the first inclined surface and the second inclined surface during pressing so that it can be correctly pressed and formed.

[0019] The pressure-bearing mold is composed of a plurality of vertically arranged first support plates 9; the outer side wall of the pressure-bearing mold is provided with a first support bar 10 connecting all the first support plates 9. The pressure-bearing mold is generally made of iron. The pressure-bearing mold made of a whole piece of iron is too heavy, and it is difficult to install it on the press machine and it is also difficult to disassemble it. Therefore, multiple first support plates 9 are used to combine into a pressure-bearing mold, and there are gaps between adjacent first support plates 9 to reduce the mass of the pressure-bearing mold. The upper surface composed of the first support plates 9 is a spiral curved surface.

[0020] The first support plate 9 is fixedly connected to the first base 3, the first support bar 10 and the first arc plate by welding, and the height of the first arc plate is higher than the pressure-bearing mold.

The advantage of this connection method is that the upper half mold 2 can be directly assembled on the lower workbench by modularizing, and spiral plates of different specifications can be produced by making first support plates 9, second support bars 12, and first arc plates of different specifications.

[0022] The pressing die is composed of a plurality of vertically arranged second support plates 11; the outer side wall of the pressure-bearing die is provided with a second support bar 12 connecting all the second support plates 11, and the inner side wall of the pressing die is provided with a third support bar 13 connecting all the second support plates 11. The lower surface of the second support plates 11 is a spiral curved surface.

[0023] The second support plate 11 can be fixed to the second base 5, the second support bar 12 and the third support bar 13 by welding. In another connection method: a second threaded hole is provided at the bottom of the second support plate 11, a second circular hole corresponding to the second threaded hole is provided on the second base 5, and a third bolt passes through the second circular hole from the bottom of the second base 5 to connect with the second threaded hole; a third circular hole is provided through the side of the second support plate 11, and a fourth circular hole corresponding to the third circular hole is provided on the second support bar 12 and the third support bar 13, and a fourth bolt passes through the first receiving circular hole and the fourth circular hole at the same time to fix the second support plate 11 to the third support bar 13 and the second support bar 12.
