Description

Technical Field

[0001] The present invention relates to the technical field of instrument production, and in particular to high-precision molding equipment and a manufacturing process for an elastic element of a pressure instrument. Background Art

[0002] The elastic element in the pressure instrument is the core component that converts the pressure signal into mechanical displacement. Its performance directly affects the accuracy and reliability of the instrument. The elastic elements in the pressure instrument include: spring tube, diaphragm, diaphragm box, bellows and spring.

[0003] In the existing technology, the production of diaphragms is divided into stamping and laser cutting. In order to ensure the accuracy of the diaphragm, laser cutting is mostly used for production. However, during the cutting process, the metal particles generated by the cutting are easily attached to the space between the metal plate and the supporting component before solidification. After solidification, the diaphragm and the supporting component will be adhered, and the bottom will be uneven, requiring secondary grinding and polishing, which increases the production difficulty and reduces the production efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-precision forming device and manufacturing process for the elastic element of a pressure gauge, so as to solve the problem proposed in the above-mentioned background technology that during the laser cutting machine cutting process, the metal particles generated by the cutting are easily attached to the space between the metal plate and the supporting component before solidification. After solidification, the diaphragm and the supporting component will be adhered, and the bottom will be uneven, requiring secondary grinding and polishing, thereby increasing the production difficulty and reducing the production efficiency.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-precision molding device and manufacturing process for elastic elements of pressure instruments, comprising a body mechanism, the body mechanism comprising a support frame, a bearing mechanism is provided at the upper end of the support frame, the bearing mechanism comprises a support seat, a workpiece placement mechanism is provided at the upper end of the support seat, the workpiece placement mechanism comprises a support bracket, an inclined guide plate is fixedly connected to the interior of the support seat, a discharge port is fixedly connected to the middle part of the lower end of the inclined guide plate, connecting pipes are fixedly connected to both ends of the support bracket, a winding bin is fixedly connected to both ends of the support bracket, and a winding mechanism is fixedly connected to both ends of the winding bin.

At the same time, the connecting pipe is placed on both sides of the support frame to concentrate the air flow on the bottom surface of the plate for flow. In this way, the air flow ejected by the laser cutting head during cutting is combined to adsorb the unsolidified metal particles, thereby avoiding the adhesion of the formed diaphragm to the No. 2 support frame. In this way, the smoothness of the diaphragm surface after production can be guaranteed, which is convenient for subsequent polishing and improves production efficiency.
