Description

Technical Field

[0001] This utility model relates to the field of gasket processing, and in particular to a limiting tooling for gasket stamping. Background Technology

[0002] A gasket, also known as a washer, is a part placed between a connected component and a nut. It is generally a flat metal ring used to protect the surface of the connected component from scratches by the nut and to distribute the pressure exerted by the nut on the connected component. Gaskets are typically manufactured using long plate stamping. During stamping, to prevent the center of the material from warping, tooling such as a pressure plate is needed to hold the material in place.

[0003] Current fixed tooling typically uses a pressure plate to limit the position of the raw material. However, because the raw material needs to move, this results in significant wear on the pressure plate, which can damage the raw material and reduce the surface quality of the product. Therefore, it is necessary to improve this structure to overcome the aforementioned drawbacks. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a limiting tooling for gasket stamping. This utility model is achieved through the following technical solution:

[0005] A limiting fixture for stamping gaskets includes a base plate. Several pressure roller mechanisms are symmetrically arranged on the base plate. Each pressure roller mechanism includes a rotating rod and a pressure roller. The rotating rod is rotatably connected to the base plate, and the pressure roller is rotatably mounted on the rotating rod. The pressure roller mechanism also includes a sliding block, which is slidably mounted on the side of the base plate and contacts the rotating rod.

[0006] In the above technical solution: the base plate is used to set the other components; the pressure roller mechanism is used to limit the arching of the raw material in the middle; the rotating rod is used to realize the change of the pressure roller position; the pressure roller is used to contact the raw material and reduce friction; the sliding block is used to lock the rotating rod after it rotates to the working position, so that it remains in the working position.

[0007] A further feature of this invention is that the pressure roller mechanism includes a fixing block and a guide rail. The fixing block is fixed to the side of the base plate, and the guide rail is also disposed on the side of the base plate. The guide rail runs vertically, and the guide rail is slidably connected to the sliding block.

[0008] In the above technical solution: the fixed block is used to limit the lowest position of the sliding block; the guide rail is used to limit the sliding direction of the sliding block.

[0009] A further feature of this invention is that a guide rod is fixedly connected to the sliding block, and the guide rod passes through the fixed block. A spring is sleeved on the guide rod, with one end of the spring contacting the fixed block and the other end contacting the sliding block.

[0010] In the above technical solution: the guide rod is used to improve the stability of the sliding block; the spring is used to enable the sliding block to automatically return to its original position to lock the rotating rod when the rotating rod rotates to the working position, so that the pressure roller on the rotating rod remains in contact with the raw material.

[0011] A further feature of this invention is that a limit block is fixedly provided at the end of the guide rod away from the sliding block.

[0012] In the above technical solution: the limiting block is used to limit the highest position of the sliding block's movement, preventing the spring from pushing the guide rod out as a whole.

[0013] A further feature of this invention is that a step is provided on each of the two sides of the upper surface of the base plate, the rotating rod is rotatably disposed at the step, and the width of the step is the same as the width of the rotating rod.

[0014] In the above technical solution: the step limits the rotation angle of the rotating rod to 90 degrees; the step is used to ensure that when the rotating rod rotates to the working position, the bottom of the rotating rod will not obstruct the sliding of the sliding block.

[0015] A further feature of this invention is that the rotating rod is L-shaped, and the pressure roller is rotatably mounted on the horizontal portion of the rotating rod.

[0016] In the above technical solution: the rotating rod is L-shaped, so that when the sliding block contacts the vertical part of the rotating rod and achieves the limit, the pressure roller on the horizontal part of the rotating rod can maintain pressure on the raw material plate.

[0017] A further feature of this invention is that the cross-section of the guide rail is "T" shaped.

[0018] In the above technical solution, the guide rail is T-shaped, which allows the sliding block to better apply limiting support force to the rotating rod.

[0019] This utility model discloses a limiting fixture for gasket stamping, which, compared with the prior art:

[0020] This utility model, by setting up a pressure roller mechanism, ensures that the raw material always remains in contact with the pressure roller during movement, reducing the wear of the pressure roller mechanism. In addition, the rotating rod can rotate, making feeding more convenient and eliminating the need to repeatedly disassemble the pressure plate.

[0021] This invention, by setting up a sliding block, a guide rod, and a spring, allows the sliding block to limit the rotation rod when it is in the working position, thereby ensuring close contact between the pressure roller and the raw material and improving the effect of this tooling.
