The invention provides a press-cutting forming processing method of a rubber sealing ring, which aims to solve the following problems in the processing process of a counter-mouth sealing ring at present: (1) when the rubber sheet is subjected to press cutting, the annular blade is directly perpendicular to the rubber sheet to be subjected to press cutting, and the smooth cutting surface is difficult to ensure; the annular blade is perpendicular to the rubber sheet and rotates for press cutting at the same time, so that the smoothness of a cutting surface can be improved, but the rubber sheet is easy to synchronously rotate along with the annular blade under the action of friction force in the cutting process, and the cutting efficiency is reduced; (2) after the rubber sheet is subjected to press cutting, the rubber sealing ring which is cut off can be reserved between the two annular blades, the circular rubber sheet can also be reserved in the inner side blade, the circular rubber sheet needs to be manually taken out, and the annular blade with lower efficiency easily damages an operator.
(II) technical scheme
In order to solve the technical problems, the invention adopts the following technical scheme:
a press-cutting forming processing method for a rubber sealing ring is completed by adopting a press-cutting forming processing machine for the rubber sealing ring, wherein the press-cutting forming processing machine for the rubber sealing ring comprises a horizontal base, and a plurality of supporting legs are uniformly and fixedly arranged on the lower surface of the base. The upper surface of the base is in a horizontal state and is vertically and fixedly provided with a guide rod. A horizontal lifting platform is vertically and slidably matched on the guide rod. The upper surface of the guide rod is vertically and rotatably provided with a lead screw. The lead screw penetrates through the lifting platform and is in threaded fit with the lifting platform. The top of the screw rod is fixedly provided with a rotating handle. The lower surface of the lifting platform is vertically and rotatably provided with a first annular blade and a second annular blade, the axes of which are coincident. The difference between the radius of the second annular blade and the radius of the first annular blade is the section width of the rubber sealing ring. The lifting table can be driven to slide downwards along the guide rod when the screw rod is driven to rotate by the rotating handle, and the first annular blade and the second annular blade are driven to vertically move downwards when the lifting table slides downwards.
An inner gear ring which is coincident with the axis of the first annular blade is fixedly arranged on the inner side wall of the first annular blade. And an outer gear ring which is coincided with the axis of the second annular blade is fixedly arranged on the outer side wall of the second annular blade. A first rotating shaft is vertically and rotatably arranged on the lifting platform, and a first gear which is meshed with the inner gear ring is horizontally and fixedly arranged at the bottom of the first rotating shaft. The top of the first rotating shaft is horizontally and fixedly provided with a second gear. A second rotating shaft is vertically and rotatably arranged on the lifting platform, a third gear meshed with the outer gear ring is horizontally and fixedly arranged at the bottom of the second rotating shaft, and a fourth gear is horizontally and fixedly arranged at the top of the second rotating shaft. The third rotating shaft is vertically and rotatably arranged on the upper surface of the lifting platform, and a fifth gear meshed with the second gear and the fourth gear is fixedly arranged on the third rotating shaft. The fifth gear is rotated to drive the second gear and the fourth gear to rotate, and then the first gear and the third gear are driven to rotate. The first and third gears drive the inner and outer ring gears, respectively, to rotate in opposite directions, thereby causing the first and second ring blades to rotate in opposite directions. In the process that the first annular blade and the second annular blade vertically move downwards to press and cut the rubber sheet, the first annular blade and the second annular blade apply friction forces in opposite directions to the rubber sheet, and therefore the situation that the rubber sheet rotates along with the first annular blade and the second annular blade is avoided.
A horizontal rod is fixedly mounted at the top of the guide rod, and a first sealing column and a second sealing column are vertically and fixedly mounted below the horizontal rod. The lifting platform is positioned in the first annular blade and vertically provided with a first vent groove in sliding fit with the first sealing column. A second ventilation groove in sliding fit with the second sealing column is vertically formed between the first annular blade and the second annular blade on the lifting platform. After the press cutting is finished, the rubber sealing ring is positioned between the first annular blade and the second annular blade, and the cut circular rubber sheet is positioned inside the first annular blade. The lifting platform, the first annular blade and the second annular blade are driven to vertically move upwards by reversely rotating the handle. When the first sealing column is inserted into the first vent groove and the second sealing column is inserted into the second vent groove, the air pressure inside the first annular blade and between the first annular blade and the second annular blade is increased, so that the rubber sealing ring and the circular rubber sheet fall off under the action of the air pressure.
The rubber sealing ring press-cutting molding processing machinery is adopted to perform the rubber sealing ring press-cutting molding steps as follows:
step one, fixing a rubber sheet: the rubber sheet is horizontally placed on the upper surface of the base, and the position of the rubber sheet is adjusted to enable the rubber sheet to be located right below the first annular blade and the second annular blade.
Step two, vertical cutting: the lifting table, the first annular blade and the second annular blade are driven to vertically move downwards by rotating the rotary handle so as to cut the rubber sheet in the vertical direction.
Step three, rotary cutting: the first annular blade and the second annular blade are driven to rotate in opposite directions by rotating the fifth gear, so that the rubber sheet is subjected to rotary cutting while being vertically cut until a rubber sealing ring is cut.
Step four, returning and removing materials: the lifting platform, the first annular blade and the second annular blade are driven to vertically move upwards by reversely rotating the rotating handle. The rubber sealing ring between the first annular blade and the second annular blade and the rubber disc on the inner side of the first annular blade automatically fall off under the action of air pressure.
As a preferred technical scheme of the present invention, a first sealing cylinder in sliding sealing fit with the first sealing column is vertically and fixedly installed on the upper surface of the lifting table, and a second sealing cylinder in sliding sealing fit with the second sealing column is vertically and fixedly installed on the upper surface of the lifting table. In order to improve the sealed effect of first sealed post and the sealed post of second, ensure that first sealed post inserts the inside atmospheric pressure increase of first annular blade behind the first air channel, ensure that the sealed post of second inserts atmospheric pressure increase between first annular blade and the second annular blade behind the second air channel to guarantee that rubber seal and circular rubber piece can drop under atmospheric pressure effect.
As a preferable technical scheme of the invention, the upper end face of the fifth gear is vertically and rotatably provided with a spiral grooved rod, and a horizontal plate is fixedly arranged on the horizontal rod corresponding to the spiral grooved rod. The spiral groove rod penetrates through the horizontal plate and is matched with the horizontal plate through a spiral groove. When the lifting platform drives the fifth gear and the spiral groove rod to move up and down, the spiral groove rod and the horizontal plate generate relative movement in the vertical direction and relative rotation, so that the fifth gear is driven to rotate automatically, the fifth gear does not need to be rotated manually, and the processing efficiency is improved while manpower is saved.
As a preferable technical scheme of the invention, a plurality of first rollers which are in rolling fit with the first annular blade are arranged in the lifting platform around the first annular blade so as to reduce the friction force between the interior of the lifting platform and the first annular blade and ensure the smooth rotation of the first annular blade. A plurality of second rollers which are matched with the second annular blade in a rolling manner are arranged in the lifting platform around the second annular blade so as to reduce the friction force between the interior of the lifting platform and the second annular blade and ensure the smooth rotation of the second annular blade.
As a preferred technical solution of the present invention, the upper surface of the base is provided with a first annular slot at a position corresponding to the first annular blade, and the upper surface of the base is provided with a second annular slot at a position corresponding to the second annular blade. The first annular blade inserts the rubber piece into first annular slot after cutting, and the second annular blade inserts the rubber piece into second annular slot after cutting to avoid first annular blade and second annular blade to cause the damage to the base upper surface.
As a preferable technical scheme of the invention, the upper surface of the base is provided with a plurality of annular air grooves which are superposed with the axes of the first annular blade and the second annular blade, and annular sealing plates are vertically matched in the annular air grooves in a sliding manner. The bottom surface of the annular sealing plate is horizontally and fixedly provided with a lifting plate. The base is internally provided with a holding tank in sliding fit with the lifting plate. The lead screw runs through the lifting plate and is in threaded fit with the lifting plate. The through-hole of intercommunication holding tank is seted up to the base bottom surface. When the screw rod rotates to drive the lifting platform to descend, the lifting plate is synchronously driven to descend. The lifting plate drives the annular sealing plate to descend along the annular air groove when descending, and air in the accommodating groove is discharged from the through hole. The atmospheric pressure in the annular gas tank reduces when the annular seal board descends along annular gas tank to compress tightly the sheet rubber of base upper surface through the atmospheric pressure effect, further guaranteed that the sheet rubber of pressure cutting in-process can not take place the skew.
