[0002] A cassette bottom bracket is a mechanical connection between a rotating shaft and a rotating bearing. It usually consists of two parts: an inner sleeve that is fixed to the rotating shaft at one end and an outer sleeve that is connected to the rotating bearing or other components. Mountain bike cassette bottom brackets are usually designed to be more durable and able to withstand harsh environments to meet the needs of mountain biking. They may use stronger bearings and more rigid construction to handle the challenges of bumps, impacts, and mud.

[0003] When forging the center shaft, some current cassette center shaft precision forging devices require workers to manually put the raw materials into the heating furnace for heating and then transfer them to the forging device for forming, and finally manually take out the formed center shaft, resulting in low work efficiency during forging. In addition, if the workers make operating errors in the process of clamping and transporting the raw materials, the raw materials may fall to the ground, which in turn causes damage to the raw materials and affects product quality.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a cassette-type center shaft precision forging device is provided, in order to achieve a more practical purpose. Utility Model Content

[0025] Among them, the molding mechanism includes a cooling groove 13, a lower mold 14 is installed directly above the cooling groove 13 through a bracket, an upper mold 15 is installed directly above the lower mold 14 through a bracket, a molding groove 16 is provided at the top of the lower mold 14, a molding mold 17 is installed in the molding groove 16, a through groove 18 is penetrated at the bottom end of the lower mold 14, and the through groove 18 is connected with the molding groove 16. Through the stamping of the upper mold 15, the card-type central axis can be formed into a required shape, and the excess waste generated during the molding will fall from the through groove 18 into the cooling groove 13, which is convenient for overall recycling.

[0026] Among them, a first screw rod 19 is rotatably installed in the first slide groove 4, and the first screw rod 19 passes through the front and rear sides of the first slider 5 and is threadedly connected to the first slider 5. Through the rotation of the first screw rod 19, under the limiting action of the first slide groove 4, the first slider 5 moves back and forth, and then drives the second mounting seat 7 to move through the connecting block 6, so that a pair of clamping blocks 10 can drive the central axis to move forward and backward and transport it to different processing areas for processing.

[0027] A first motor 20 is installed on one side of the first mounting seat 3 , and an output end of the first motor 20 is transmission-connected to the first screw 19 via a coupling. The first motor 20 drives the first screw 19 to rotate, thereby driving the first slider 5 to move.

[0028] Among them, a bidirectional screw 21 is rotatably installed in the second slide groove 8, and the bidirectional screw 21 passes through the left and right sides of a pair of second sliding blocks 9 and is threadedly connected with a pair of second sliding blocks 9. Through the rotation of the bidirectional screw 21, under the limiting action of the second slide groove 8, a pair of second sliding blocks 9 move toward or away from each other at the same time, driving a pair of clamping blocks 10 to move toward or away from each other at the same time, thereby realizing the clamping or loosening of the center axis.

[0032] Working principle of this embodiment: When using the cassette-type central shaft precision forging device to forge the central shaft, the staff first places the central shaft material to be forged in the middle position of a pair of clamping blocks 10, and then turns on the second motor 22. The second motor 22 drives the bidirectional screw 21 to rotate. Under the limiting action of the second slide 8, a pair of second sliders 9 move toward each other at the same time, driving a pair of clamping blocks 10 to move toward each other at the same time, clamping the central shaft material in the middle, and then turns on the first motor 20. The first motor 20 drives the first screw 19 to rotate. Under the limiting action of the first slide 4, the first slider 5 moves forward, and then drives the second mounting seat 7 to move through the connecting block 6, so that the pair of clamping blocks 10 can drive the central shaft material into the heating furnace 1 1, and then control a pair of clamping blocks 10 to loosen the middle shaft raw material and move away from the heating furnace 11, and finally open the heating furnace 11 to heat the middle shaft raw material. After the heating is completed, control the pair of clamping blocks 10 to take out the middle shaft raw material, and then turn on the third motor 23. The third motor 23 drives the first mounting seat 3 to rotate, so that the pair of clamping blocks 10 drive the middle shaft raw material to move to a position near the lower mold 14 and then place the middle shaft raw material in the forming mold 17, and then open the upper mold 15 to form the middle shaft, and the waste generated by the forming falls from the through groove 18 into the cooling groove 13 for cooling and recycling. A pair of clamping blocks 10 clamps the finished product after forming and transports it to the top of the recovery groove 12, and then loosens the finished product and drops it into the recovery groove 12 to complete the unloading.
