Technical Field
The utility model relates to a mould especially can be applied to deep groove ball bearing sealing washer assembling die.
Background
The bearing seal ring is a bearing seal component. Because the sealing of the rolling bearing can be classified into contact sealing and non-contact sealing, the contact sealing includes felt ring sealing, seal ring sealing, and the like. The non-contact type sealing comprises axial curved path sealing, radial curved path sealing, oil groove sealing, check ring sealing and the like. The function of the bearing seal is to prevent dust, water, and other debris from entering the bearing and to prevent lubricant from escaping.
The existing bearing sealing ring is assembled by adopting automatic equipment, the sealing ring is assembled by mainly depending on a die to automatically take and discharge materials and then cutting into a sealing groove of a bearing ring in a stamping mode, and the mode mainly aims at a non-contact sealing structure. And the contact sealing structure can generate the upwarp of the outer lip edge of the sealing ring and the uneven plane after being installed by utilizing the die. The assembly of contact type sealing structures is difficult to adopt the above structure.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose is, according to bearing contact sealing mechanism's design characteristic to and current bearing seal circle because of the problem that the obstructed assembly difficulty that causes greatly in the installation, provide a bearing seal circle assembly elastic mould. If an elastic die is not adopted, the sealing ring is deformed by directly stamping the plane of the sealing ring, and the technological requirements cannot be met.
The technical scheme of the utility model be, a bearing seal assembles elastic die, including outer sleeve 4, baffle supporting spring 5, baffle 6, flexible cover 7, bottom plate 8, screw thread 9 of first neck cover 1 of mould punching press, first 2, the first inner spring of punching press 3, neck cover. The die stamping head is sleeved by a die stamping head neck sleeve, the contact part of the die stamping head and the die stamping head neck sleeve is in threaded connection, a spring in the stamping head is in a compressed state and respectively props against the front end of the stamping head and a partition plate, the partition plate is movably partitioned between the spring in the stamping head and a partition plate supporting spring, the lower end plane of the die stamping head neck sleeve is also in contact with the plane of the partition plate, a partition plate supporting spring 5 is arranged in an outer sleeve 4 of the neck sleeve, and the elastic forces of the partition plate supporting spring and the spring in the stamping head are towards the stamping direction of the stamping head; the lower end of the outer sleeve 4 of the neck sleeve is provided with a bottom plate 8 for supporting the clapboard supporting spring.
The front end of the neck sleeve of the die stamping head is provided with a flexible sleeve 7.
The front end of the die stamping head 2 is provided with a convex platform.
The utility model discloses a working process, 2 front ends of mould punching press head are equipped with the protruding axle and are entangled by the sealing washer, adopt accurate central location back, utilize the mode that flexible material and spring buffering pushed down to carry out the sealing washer assembly, and the screw thread of mould punching press head 2 can be adjusted for adjust the elastic force of mould punching press head 2 at the during operation. Through the elastic force and the stamping process of the secondary spring, the problem that the assembly is difficult due to the fact that the existing bearing sealing ring is greatly blocked in the installation process is solved, if the elastic die is not adopted for stamping, the sealing ring which can be caused by directly stamping the sealing ring plane is deformed, and the technological requirements cannot be met.
Has the advantages that: to the design and the assembly characteristic of the above-mentioned contact's sealing washer, design punching press assembly die structure, the mode of simulation manual assembly sealing washer adopts accurate central positioning back, utilizes the mode that flexible material and spring buffering pushed down to carry out the sealing washer assembly to different sealing washer models, the flexible length of punching press power accessible adjustment spring adjusts sealing washer assembly pressure size. Therefore, the plane of the sealing ring is not damaged after the sealing ring is installed, and the lip edge does not have a flanging phenomenon so as to meet the technical requirements of the process.
Drawings
Fig. 1 is a schematic design diagram of the bearing seal ring assembling elastic die, i.e. the tool assembly of the present invention.
Detailed Description
As shown in the figure, the die stamping head neck sleeve 1, the die stamping head 2, the stamping head inner spring 3, the neck sleeve outer sleeve 4, the clapboard supporting spring 5, the clapboard 6, the flexible sleeve 7 and the bottom plate 8. The stamping die comprises a die stamping head neck sleeve 1, a die stamping head 2, a stamping head inner spring 3, a neck sleeve outer sleeve 4, a partition plate supporting spring 5, a partition plate 6, a flexible sleeve 7, a bottom plate 8 and threads 9. The die stamping head is sleeved by a die stamping head neck sleeve, the contact part of the die stamping head and the die stamping head neck sleeve is in threaded connection, a spring in the stamping head is in a compressed state and respectively props against the front end of the stamping head and a partition plate, the partition plate is movably partitioned between the spring in the stamping head and a partition plate supporting spring, the lower end plane of the die stamping head neck sleeve is also in contact with the plane of the partition plate, a partition plate supporting spring 5 is arranged in an outer sleeve 4 of the neck sleeve, the partition plate is arranged between the partition plate supporting spring 5 and a spring 3 in the stamping head, the upper plane of the partition plate is covered, and the elastic forces of the partition plate supporting spring and the spring in the stamping head are towards the stamping direction; the lower end of the outer sleeve 4 of the neck sleeve is provided with a bottom plate 8 which is used for supporting the clapboard supporting spring. The die stamping head neck sleeve 1 and the outer sleeve 4 of the neck sleeve are rigidly fixed; the die stamping head neck sleeve 1 is fixed with the die stamping head 2 through threads, the die stamping head can be used for adjusting the extending position of the die stamping head neck sleeve 1, and the outer sleeve 4 of the neck sleeve is provided with a flexible sleeve 7 at the front ends of the die stamping head 2, the stamping head inner spring 3 and the die stamping head neck sleeve due to the influence of the adjusting position on the elastic force of the stamping head inner spring 3.
