The lower die comprises an annular guide ring 7 arranged on the workbench, and the annular guide ring 7 is used for positioning the wheel rim 20. Specifically, the upper die is a rigid structure consisting of a connecting plate 1, a first circular plate 3, an annular pressing ring 4 and a second circular plate 6, the upper die is driven by an oil press to reciprocate along the vertical direction, and the first circular plate 3 plays a role in transitional connection.
Further, the outer diameter of the second annular plate 6 is matched with the outer diameter of the tire 10 to be pressed, and the inner diameter of the second annular plate 6 is slightly larger than the outer diameter of the rim 20 to be pressed.
Further, the outer diameter of the annular pressing ring 4 is matched with the inner diameter of the retainer ring 30 to be pressed.
Further, the outer diameter of the annular guide ring 7 is matched with the inner diameter of the rim 20 to be pressed.
The working process of the invention is as follows:
as shown in fig. 2, the annular guide ring is firstly placed on the workbench, the rim is placed right above the annular guide ring, the tire is placed right above the rim, and at this time, the oil press is started, and the oil press drives the upper die to move downwards, so that the rim is pressed into the tire; as shown in fig. 3, the upper die moves upwards, the check ring is placed right above the tire, the upper die moves downwards, the second circular plate continues to move downwards when contacting with the upper surface of the tire, the tire is compressed and extruded, at the moment, the gap between the tire and the rim is increased, and the annular pressing ring of the upper die presses the check ring to the installation position between the tire and the rim; as shown in fig. 4, the tire 10, rim 20, and retainer ring 30 are mounted.
The invention also aims to provide a composite method for press fitting of a solid tire rim of a forklift, which comprises the following steps:
(1) Placing the annular guide ring on a workbench;
(2) Sequentially placing a rim and a tire right above the annular guide ring, and keeping the centers consistent;
(3) Starting the oil press, driving the upper die to move downwards by the oil press, and pressing the rim into the tire through the second circular ring plate;
(4) The oil press drives the upper die to move upwards, the check ring is placed right above the tire, and the centers of the check ring and the tire are kept consistent;
(5) The oil press drives the upper die to move downwards, and the second circular plate firstly realizes compression and extrusion on the tire in the descending process, so that the gap between the tire and the rim is increased; then, the descending annular pressing ring presses the check ring to the mounting position between the tire and the rim;
(6) And (5) finishing press fitting.
