[0002] The tapered roller bearing stamping device is a specialized piece of equipment used to produce key components of tapered roller bearings. It is primarily used in automated production processes to stamp materials into specific shapes for bearing cages, including components such as stamped pistons and stamping rods, achieving high-efficiency production. Currently, after stamping the workpiece, operators need to manually demold it. Because the workpiece and mold are too tightly fitted, demolding is difficult. Therefore, a tapered roller bearing stamping device that facilitates demolding is needed. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a tapered roller bearing stamping device that facilitates demolding. It solves the problem that after the tapered roller bearing stamping device has stamped the workpiece, the operator needs to manually demold the workpiece because the workpiece and the mold are too tightly attached, making it difficult to demold the workpiece.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tapered roller bearing stamping device for easy demolding, comprising a worktable, a first mold fixedly connected to the worktable, a second mold provided on one side of the first mold, two first U-shaped frames fixedly connected to one side of the second mold, a rotating arm hinged to the first U-shaped frame by a pin, a second U-shaped frame fixedly connected to one end of the rotating arm, a threaded plate installed on one side of the second U-shaped frame, a threaded rod threadedly engaged on the threaded plate, a spring sleeved on the threaded rod, both ends of the spring fixedly connected to the threaded plate, two threads in opposite directions on the threaded rod, one end of the threaded rod connected to a support plate through a bearing, the other end of the threaded rod being engaged through the support plate, a motor installed on one end of the threaded rod, and the motor fixedly connected to the worktable.

[0005] As a further embodiment of this utility model: a bracket is fixedly connected to the workbench, a cylinder is installed on the bracket, a piston rod is fixedly connected to the bottom side of the cylinder, the piston rod is through-engaged with the bracket, a connecting plate is fixedly connected to the bottom end of the piston rod, and a punch is installed on the bottom side of the connecting plate.

[0006] As a further embodiment of this utility model: two telescopic rods are installed on the connecting plate, and the top ends of the telescopic rods are fixedly connected to the bracket.

[0008] As a further embodiment of this utility model: two sliding grooves are provided on the worktable, and a slider is slidably engaged with the inner wall of the sliding groove, and the slider is fixedly connected to the bottom side of the second mold.

[0009] As a further embodiment of this utility model: four rubber pads are installed on the bottom side of the workbench, and the four rubber pads are respectively arranged at the four corners of the bottom side of the workbench.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This easy-to-demold tapered roller bearing stamping device, through the setting of a first mold, a second mold, a first U-shaped frame, a rotating arm, a second U-shaped frame, a spring, a threaded plate, a threaded rod, and a motor, allows the operator to start the motor after the workpiece is processed, driving the threaded rod to rotate. Because the threaded rod has threads in opposite directions, it can push the two threaded plates to move in opposite directions and stretch the spring. The threaded plates drive the second U-shaped frame and the rotating arm to move, and the rotating arm pulls the first U-shaped frame and the second mold to move until the second mold is completely separated from the workpiece. The operator can then remove the workpiece, which facilitates quick demolding of the processed workpiece and prevents the workpiece from sticking tightly to the mold, thus saving the operator a lot of time and effort when removing the workpiece and improving the ease of use of the device.

[0012] 2. This easy-to-demold tapered roller bearing stamping device, through the setting of a bracket, cylinder, piston push rod, telescopic rod, connecting plate and punch, allows for automatic and efficient stamping of the workpiece. When stamping the workpiece, the operator activates the cylinder on the bracket, which extends the piston push rod and pushes the connecting plate downward. The connecting plate then pushes the punch downward, thereby performing automatic and efficient stamping of the workpiece. This prevents the stamping process from being too complicated and cumbersome, which would reduce the working efficiency of the device, thus improving the functionality and practicality of the device.

Detailed Implementation

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a tapered roller bearing stamping device that is easy to demold, including a worktable 1, a bracket 9 fixedly connected to the worktable 1, a cylinder 10 installed on the bracket 9, a piston push rod 11 fixedly connected to the bottom side of the cylinder 10, the piston push rod 11 being through-engaged with the bracket 9, a connecting plate 13 fixedly connected to the bottom end of the piston push rod 11, and a stamping die 14 installed on the bottom side of the connecting plate 13;

[0020] Two telescopic rods 12 are installed on the connecting plate 13. The top ends of the telescopic rods 12 are fixedly connected to the bracket 9. Because of the telescopic rods 12, when the connecting plate 13 moves, the telescopic rods 12 extend or retract together with the connecting plate 13. This facilitates limiting the movement of the connecting plate 13 while ensuring its normal movement and preventing accidental displacement during movement, thus improving the stability of the connecting plate 13 during movement. A first mold 2 is fixedly connected to the workbench 1. A second mold 3 is provided on one side of the first mold 2. Two first U-shaped frames 4 are fixedly connected to one side of the second mold 3. A rotating arm 5 is hinged to the first U-shaped frame 4 by a pin. A second U-shaped frame 6 is fixedly connected to one end of the rotating arm 5. The first mold 2 A groove 15 is provided on the worktable 1 below, and a storage box 16 is provided below the groove 15. The storage box 16 is slidably engaged with the inner wall of the worktable 1. A handle 17 is fixedly connected to one side of the storage box 16. Because of the storage box 16, when the device performs stamping processing on the workpiece and generates chips, the chips fall into the storage box 16 through the groove 15 and accumulate. After the storage box 16 is full of chips, the operator pulls the handle 17, and the handle 17 drives the storage box 16 to accumulate in the worktable 1 until the storage box 16 is completely separated from the worktable 1. This facilitates the centralized processing of the chips generated during processing, prevents the chips from accumulating on the worktable 1, and affects subsequent stamping processing, thus improving the functionality of the device.

[0021] Two sliding grooves 18 are provided on the workbench 1. A slider 19 is slidably engaged with the inner wall of the sliding groove 18. The slider 19 is fixedly connected to the bottom side of the second mold 3. Because of the sliding grooves 18, when the second mold 3 moves, it drives the slider 19 to slide within the sliding grooves 18, thereby limiting the movement of the second mold 3 and preventing accidental tilting or displacement, thus improving the stability of the second mold 3 during movement. A threaded plate 21 is installed on one side of the second U-shaped frame 6. A threaded rod 7 is threadedly engaged with the threaded plate 21. A spring 22 is sleeved on the threaded rod 7. The two ends of the spring 22 are fixedly connected to the threaded plate 21. There are two square... The threaded rod 7 has one end connected to the support plate 23 via a bearing, and the threaded rod 7 is also connected to the support plate 23 through a through-hole engagement. A motor 8 is installed at one end of the threaded rod 7, and the motor 8 is fixedly connected to the worktable 1. Four rubber pads 20 are installed on the bottom side of the worktable 1, and the four rubber pads 20 are respectively arranged at the four corners of the bottom side of the worktable 1. Because the rubber pads 20 are installed on the bottom side of the worktable 1, they prevent the bottom side of the worktable 1 from directly contacting the ground, preventing the bottom side of the worktable 1 from being too smooth, which would make the device easily slip due to external forces, thereby affecting the normal stamping process of the workpiece and improving the overall stability of the device.

[0022] The working principle of this utility model is as follows: When stamping a workpiece, the operator places the bearing workpiece on the first mold 2 and the second mold 3, and then activates the cylinder 10 on the bracket 9. The cylinder 10 causes the piston rod 11 to extend and push the connecting plate 13 downward. The connecting plate 13 pushes the punch 14 downward, thereby performing automatic and efficient stamping of the workpiece. When the stamping process generates debris, the debris falls into the storage box 16 through the groove 15 and accumulates. After the storage box 16 is full of debris, the operator pulls the handle 17, which causes the storage box 16 to accumulate in the worktable 1. The process continues until the storage box 16 is completely separated from the worktable 1, thereby collecting and processing the debris generated during processing. After the workpiece is processed, the operator starts the motor 8 to drive the threaded rod 7 to rotate. Because the threaded rod 7 has threads in opposite directions, the threaded rod 7 can push the two threaded plates 21 to move in opposite directions and stretch the spring 22. The threaded plates 21 drive the second U-shaped frame 6 and the rotating arm 5 to move. The rotating arm 5 pulls the first U-shaped frame 4 and the second mold 3 to move until the second mold 3 is completely separated from the workpiece. The operator then takes out the workpiece, thereby quickly demolding the processed workpiece.
