Description

Technical Field

[0001] This utility model belongs to the field of bearing heat treatment technology, and relates to a mold removal support device for a quenching mold of the inner ring of a self-aligning roller bearing. Background Technology

[0002] After the secondary quenching of the inner ring of a carburized steel bearing is completed, the mold needs to be removed for subsequent processes. Because the ring shrinks and adheres tightly to the mold after secondary quenching, the current method for demolding involves lifting the mold and ring with a hoist. During demolding, the mold is then struck at two points held by clamps. Using a hammering tool to remove the ring takes a considerable amount of time and is labor-intensive. Larger rings grip the mold more tightly, making hammering even more difficult and time-consuming, severely impacting production efficiency. Furthermore, striking the ring while suspended in the air is extremely difficult and requires highly skilled operators; even a slight misalignment can damage the product, resulting in scrap. Utility Model Content

[0003] This utility model proposes a mold removal support device for the quenching mold of the inner ring of a self-aligning roller bearing. The device uses claws to support the middle edge of the inner ring along the circumference of the ring, which can solve the problem of difficult mold removal of the bearing ring after secondary quenching. It reduces the labor intensity of operators, saves time and effort, and is convenient and quick, while reducing the risk of product damage caused by repeated impacts.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A demolding support device for a quenching mold of the inner ring of a self-aligning roller bearing, the demolding support device having multiple claws for supporting the middle edge of the inner ring of the self-aligning roller bearing; the upper end of each claw is bent to one side to form a support platform for supporting the middle edge, and the lower end of each claw is bent to one side to form a fixing platform for fixing to a base; the inner ring of the self-aligning roller bearing is supported on the base by the claws; the base is a circular disk with a through hole in the middle; the base has multiple sliding grooves corresponding to the claws; screws that can move within the corresponding sliding grooves are provided; the upper end of each screw corresponds to a screw hole on the fixing platform of the claw, so that after the screw slides, it is fixedly connected to the claw corresponding to the one supported on the middle edge.

[0006] The chassis has lifting rings for easy lifting; the lifting rings are multiple rings evenly distributed along the circumference.

[0007] This utility model proposes a demolding support device for a self-aligning roller bearing inner ring quenching mold. It utilizes chucks as fulcrums to support the inner ring of the self-aligning roller bearing. Multiple support points allow the mold to be easily knocked off, significantly reducing manual labor intensity and improving demolding efficiency. Furthermore, this device ensures the ring encased in the mold sits securely on the chassis, avoiding the safety risks and difficulty in accurately striking the impact surface previously encountered during suspended operations, thus reducing product impact. The opening diameter of the chucks can be adjusted according to the size of the inner ring's center edge, allowing one set of support devices to meet the needs of supporting the center edge of inner rings of different sizes, thereby achieving the purpose of demolding.

[0011] The present invention will be described in detail with reference to the accompanying drawings and specific embodiments:

[0012] like Figure 1 As shown, and in combination Figure 2 A mold removal support device for a quenching mold of the inner ring of a self-aligning roller bearing is disclosed. The mold removal support device has six claws 2 for supporting the middle edge of the inner ring 1 of the self-aligning roller bearing. The upper end of each claw 2 is bent to one side to form a support platform for supporting the middle edge, and the lower end of each claw 2 is bent to one side to form a fixing platform for fixing to a base plate 5. The inner ring 1 of the self-aligning roller bearing is supported on the base plate 5 by the claws 2. The base plate 5 is a circular disk with a through hole in the middle. The base plate 5 has a plurality of sliding grooves corresponding to the claws. Screws that can move within the sliding grooves are provided. The upper end of each screw corresponds to a screw hole on the fixing platform of the claw, so that after the screw slides, it is fixedly connected to the claw corresponding to the one supported on the middle edge.

[0013] The chassis has lifting rings 7 for easy lifting; the lifting rings 7 are multiple rings evenly distributed along the circumference.

[0014] When using this utility model: Place the base 5 of the support device on the ground, put the screws 3 into the slide groove, align the fixing holes of the claws 2 with the screws and insert them one by one, and pre-tighten the lower end face of the claws with the nuts 4; adjust the opening diameter of the 6 claws according to the outer dimensions of the inner ring middle edge, and adjust the claws to a suitable position, so that the upper end face of the 6 claws can just support the end face of the inner ring middle edge; place the mold 6 along with the self-aligning roller bearing inner ring 1 on the claws 2, and lock the nuts 4; the claws 2 act as a fulcrum to support the inner ring middle edge, and use a hammering tool to strike the mold 6 downwards to make it demold smoothly; when changing product models, simply adjust the device according to the outer dimensions of the middle edge using the above method.
