Description

Technical Field

[0001] This invention relates to the field of production equipment technology, and in particular to a device for integral pressing and shaping of a fan-shaped corrugated filter plate and its usage method. Background Technology

[0002] Currently, in existing corrugated fan-shaped filter plates, three out of four sides have a peak-and-trough structure, with only the starting edge being flat. When the corrugated fan-shaped filter plate is assembled with the surrounding frame, the peaks and troughs of the curved and long oblique edges of the corrugated fan-shaped filter plate are difficult to fit closely with the frame, resulting in excessive gaps between the filter plate and the frame. Furthermore, the deformation of the filter plate body due to stress and molding causes differences in size between the filter plate and the peaks and troughs of the bottom transition box, creating gaps that easily lead to slurry leakage. The two filter plates are also not tightly bonded. Summary of the Invention

[0003] This invention proposes an integral edge pressing and shaping device for a fan-shaped corrugated filter plate and its usage method, which solves the problems of filter plate deformation, peripheral seal leakage, and filter plate breakage in the prior art.

[0004] The technical solution of the present invention is implemented as follows: a fan-shaped corrugated filter plate integral pressing and shaping device includes a support platform, a lower tire is provided at the upper end of the support platform, a fan-shaped inner tire is provided above the lower tire, the inner tire is connected to the lower end of the upper tire through an elastic connecting component, and the upper end of the upper tire is connected to the upper tire connecting seat.

[0005] Furthermore, the lower end of the inner tube is provided with a first corrugated surface, the outer circular end of the inner tube is provided with an arc-shaped positioning surface, the side of the inner tube near the corrugated edge of the first corrugated surface is provided with an inclined edge positioning surface, the lower end of the upper tire is provided with an inner tube mounting groove, an arc-shaped transition surface is provided in the inner tube mounting groove at the position corresponding to the arc-shaped positioning surface, and an inclined edge transition surface is provided in the inner tube mounting groove at the position corresponding to the inclined edge positioning surface.

[0006] Furthermore, the upper end of the lower tire is provided with a second corrugated surface that mates with the first corrugated surface. The outer circular end of the second corrugated surface is provided with an arc-shaped inner support surface. One side of the corrugated inclined edge of the second corrugated surface is provided with an inclined inner support surface.

[0008] Furthermore, a guide post is provided at the upper end of the lower tire, and a guide post sleeve that cooperates with the guide post is provided on the upper tire, with the upper end of the guide post slidingly placed inside the guide post sleeve.

[0009] Furthermore, the upper tire is provided with a stepped hole, and the elastic connection component includes a polyurethane spring and a double-ended connecting stud. The lower end of the double-ended connecting stud is connected to the inner tube, a polyurethane spring is provided in the stepped hole, and the upper end of the double-ended connecting stud passes through the polyurethane spring and is connected to the washer and nut in sequence.

[0010] A method for using a fan-shaped corrugated filter plate integral edge pressing and shaping device includes the following steps:

[0011] (1) The upper tire connecting seat is connected to the movable worktable, the movable worktable is connected to the hydraulic press, the support platform is set on the fixed worktable, the hydraulic press is started, and the upper tire connecting seat is driven to move upward through the movable worktable, so that the inner tube is separated from the lower tire. Under the dual action of gravity and polyurethane spring, the inner tube is separated from the upper tire. The movable worktable continues to move upward, so that the inner tube is separated from the lower tire.

[0012] (2) Place the workpiece on the second corrugated surface of the device, move the worktable downwards, the guide column enters the guide column sleeve, and the inner tube first contacts the workpiece through the first corrugated surface and presses and positions the workpiece under the action of the polyurethane spring.

[0013] (3) Continue to move the worktable downwards. The upper tire contacts the workpiece. The corrugated straight edge of the prefabricated workpiece is made by the cooperation of the inclined transition surface and the inclined inner support surface.

The crests and troughs of the workpiece are shaped by the first corrugated surface and the second corrugated surface. Hold the pressure for 1 to 2 minutes. Move the worktable upwards to a suitable distance, take out the workpiece, and complete the overall pressing and shaping of the workpiece.

[0014] The beneficial effects of this technical solution are as follows: By using the inclined transition surface and the inclined inner support surface to cooperate with the corrugated inclined straight edge of the prefabricated workpiece, and by using the arc transition surface and the arc inner support surface to cooperate with the outer circular edge of the prefabricated workpiece, a 50° transition is achieved with the filter plate. Under the action of the hydraulic press, the upper mold, the workpiece, and the lower mold are bonded together. The first corrugated surface and the second corrugated surface molds shape the filter plate. The outer circular edge of the filter plate is flattened by the upper arc pressing plane and the lower arc pressing plane, and the corrugated inclined straight edge is flattened by the upper inclined edge pressing plane and the lower inclined edge pressing plane, so that the inclined straight edge of the filter plate becomes a flat plate structure like the starting edge of the filter plate body. This can effectively solve the problems of filter plate body deformation, excessive gaps at the connection between the filter plate body and the frame, transition box, etc., and filter plate breakage.
