Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearing production, in particular to a rolling machine for sliding bearings. Background Technique
[0002] A sliding bearing, that is, a bearing that works under sliding friction. The sliding bearing works smoothly, reliably and noiselessly. Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil and does not come into direct contact, which can greatly reduce friction loss and surface wear. The oil film also has a certain vibration absorption capacity. The sliding bearing forms a cylindrical structure by rolling a metal plate through a rolling machine. When rolling and processing in the traditional way, rolling and processing are carried out by matching two arc-shaped grooves with a cylinder.
[0003] However, when rolling and processing, a large force will be applied to the plate. Since the atoms or molecules inside the plate change their positions or arrangements when subjected to external forces, the mutual forces between atoms change, resulting in stress. If not eliminated, it will damage the structure and accelerate fatigue, thus reducing the service life. Therefore, we propose a rolling machine for sliding bearings. Content of the Utility Model
[0004] The purpose of the utility model is to provide a rolling machine for sliding bearings. By using the arc grooves of the fixed block and the moving block, and cooperating with the movable abutting column, the plate can be rolled and processed. After the plate is rolled, the induction coil can be used to heat the annular plate through electromagnetic induction, so as to achieve the purpose of eliminating the stress of the annular plate, avoid structural damage and ensure the service life, and solve the problems raised in the background technique.
[0005] To achieve the above purpose, the utility model provides the following technical scheme: A rolling machine for sliding bearings, including a table, a fixed block and a moving block. The fixed block is fixed on the side surface of the table. Above the table on the other side of the fixed block, an upper side plate is vertically fixed. A first electric push rod is horizontally installed on the outer side surface of the upper side plate. The moving block is fixed at the end of the first electric push rod.

The extending end of the second electric push rod is fixed with a bottom block, and an abutting column that can slide through to between the fixed block and the moving block is fixed above the bottom block.
[0006] By adopting the above technical scheme, first, the arc groove of the fixed block, the movable abutting column and the arc groove of the moving block are used to roll and process the plate, and then the first reaction coil and the second induction coil in the fixed block and the moving block are used to heat the rolled plate through electromagnetic induction to achieve the purpose of eliminating the stress of the rolled plate.
[0007] Optionally, a through opening is provided on the tabletop surface between the fixed block and the moving block, and the abutting post penetrates through the tabletop through the through opening.
[0008] By adopting the above technical solution, driven by the second electric push rod, the abutting post can slide left and right in the through opening.

Specific implementation manner
[0025] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a coiling machine for a sliding bearing, including a tabletop 1, a fixed block 2 and a moving block 3. Support feet 12 are supported and fixed at the four corners of the bottom of the tabletop 1. There are at least four support feet 12, and the heights of all the support feet 12 are the same, realizing the horizontal support of the tabletop 1 in the horizontal direction.
[0026] The fixed block 2 is directly fixed on the left surface of the tabletop 1. Above the right side of the tabletop 1 opposite to the fixed block 2, an upper side plate 4 is vertically fixed. A first electric push rod 41 is horizontally installed on the right surface of the upper side plate 4. The extending end of the first electric push rod 41 penetrates to the left side of the upper side plate 4, and the moving block 3 is fixed at the end of the first electric push rod 41. Arc grooves 5 are opened on the opposite surfaces of the fixed block 2 and the moving block 3. The arc groove 5 on the surface of the fixed block 2 has the same size as the arc groove 5 on the surface of the moving block 3. The first electric push rod 41 can conveniently push the moving block 3 towards the fixed block 2. When the fixed block 2 and the moving block 3 are aligned, the two arc grooves 5 are spliced into a complete circle.
[0027] A lower side plate 6 is vertically fixed to the bottom surface of the tabletop 1 below the upper side plate 4. A second electric push rod 61 is horizontally fixed to the outer surface of the lower side plate 6. The extending end of the second electric push rod 61 penetrates to the left side of the lower side plate 6. A bottom block 611 is fixed to the extending end of the second electric push rod 61. A resisting column 612 is fixed above the bottom block 611. A vertically-through penetrating opening 11 is horizontally formed on the surface of the tabletop 1 at the position of the resisting column 612. The penetrating opening 11 is arranged between the fixed block 2 and the moving block 3, so that the upper part of the resisting column 612 can slide through the penetrating opening 11 to the upper side of the tabletop 1, and the resisting column 612 is located between the fixed block 2 and the moving block 3. The diameter of the resisting column 612 is smaller than the inner diameter of the arc groove 5, and the resisting column 612 and the center points of the arc grooves 5 on both sides are located on the same straight line. The plate can first cooperate with the arc groove 5 of the fixed block 2, and the resisting column 612 bends the plate into a semi-circular arc shape. Then, the second electric push rod 61 pushes the bottom block 611 to the left, and drives the resisting column 612 to approach the fixed block 2 to the left through the bottom block 611. The moving block 3 continues to move towards the fixed block 2 and presses the arc groove 5 of the moving block 3 against the outer ring of the plate to roll the plate into a circle and tightly attach it between the arc grooves 5 and the resisting column 612 on both sides.
[0028] A first induction coil 21 and a second induction coil 31 are respectively embedded in the fixed block 2 and the moving block 3 located on the side of the arc groove 5. The first induction coil 21 is close to the arc groove 5 of the fixed block 2, and the second induction coil 31 is close to the arc groove 5 of the moving block 3. After the rolling process, the first induction coil 21 and the second induction coil 31 can be immediately energized to heat the rolled plate by electromagnetic induction, so as to achieve the purpose of eliminating stress of the rolled plate.
[0029] During use, the first induction coil 21 and the second induction coil 31 are both connected to their controller through wires, and the first electric push rod 41 and the second electric push rod 61 are both connected to the industrial control equipment. First, the plate for rolling is placed close to the side of the fixed block 2, and then the second electric push rod 61 is controlled to drive the bottom block 611 and the resisting column 612 to move towards the fixed block 2. By using the pushing action of the resisting column 612 and cooperating with the arc groove 5 of the fixed block 2, the plate can be first pressed into a semi-circular arc shape until the resisting column 612 presses tightly against the side of the plate and makes the plate bend and deform to tightly attach to the inner surface of the arc groove 5 of the fixed block 2. Then, the first electric push rod 41 is controlled to drive the moving block 3 to approach the fixed block 2, and the moving block 3 abuts against the other side of the plate through the arc groove 5, and finally the plate is squeezed and bent into a circular ring shape and placed between the arc grooves 5 of the fixed block 2 and the moving block 3 and the resisting column 612. Then, the first induction coil 21 and the second induction coil 31 are energized to work, and the induction magnetic field is used to quickly heat the rolled circular ring, so as to achieve the stress elimination of the rolled ring plate. After that, the work of the first induction coil 21 and the second induction coil 31 is stopped. After the circular plate naturally cools down, the first electric push rod 41 and the second electric push rod 61 can be controlled to drive the moving block 3 and the resisting column 612 to move to the right, and then the circular plate can be taken away for processing the sliding bearing.
