Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sensor diaphragm processing, and particularly relates to a corrugated forming mechanism for a sensor diaphragm. Background Art
[0002] The sensor diaphragm is an important component in a sensor. It serves as the sensitive part of the sensor and can convert external pressure or the pressure of a liquid into force. When the liquid level changes, the diaphragm will undergo minute deformation, thereby transmitting these pressure changes to the interior of the sensor, enabling the sensor to measure the pressure of the liquid or the liquid level height. In addition, the diaphragm is usually designed to have corrosion resistance, high temperature resistance, or pressure resistance characteristics to protect the components inside the sensor from being eroded or damaged by liquids or gases. They can also prevent dust, impurities, etc. from entering the sensor, thus playing a protective role.
[0003] The design of the corrugated diaphragm with annular concentric corrugations can generate a large displacement when subjected to pressure. This design not only increases the displacement amount at the center of the diaphragm but also enables the diaphragm to strain and move towards the side with lower pressure when subjected to different pressures, thereby generating a displacement that has a certain relationship with the pressure difference. This displacement is one of the important parameters for the operation of the sensor and is directly related to the sensitivity and measurement accuracy of the sensor.
[0004] The current corrugated diaphragm forming equipment has low precision and low efficiency. Since the sensor diaphragm is a high-precision part, strict quality control is required, and the processing efficiency needs to be improved while ensuring precision. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a corrugated forming mechanism for a sensor diaphragm to solve the problems of unstable forming quality and low efficiency in the processing of corrugated diaphragms.
[0006] Technical solution: The utility model provides a corrugated forming mechanism for a sensor diaphragm, including: a base, a support frame, a corrugated forming mechanism, a pressing mechanism, and a driving mechanism; the support frame is arranged on the base in a three-sided surrounding structure, with one side open as the diaphragm feeding port, and a top plate is provided above the support frame; the corrugated forming mechanism includes: a forming clamp seat, a corrugated forming die, and a limiting and fixing component. The forming clamp seat is arranged above the base, a backing plate is provided between the forming clamp seat and the base, a hole is provided in the middle of the forming clamp seat, and a corrugated forming die is arranged in the hole. The corrugated forming die is of a cylindrical structure, and there is a corrugated structure on the upper surface. The limiting and fixing component is arranged on the forming clamp seat and surrounds the corrugated forming die to play a role in clamping and limiting; the pressing mechanism includes: guide posts, a lower pressing plate, a forming press head, and a lower pressing head. There are two guide posts, which vertically pass through the top plate and are connected to the lower pressing plate below. A through hole is provided in the middle of the lower pressing plate, and a forming press head is arranged below the through hole. The lower pressing head passes through the middle of the top plate and is aligned with the through hole below; the driving mechanism is arranged above the top plate, and the driving end below is connected to the lower pressing head.
[0007] Further, in the above-mentioned corrugated forming mechanism for a sensor diaphragm, grooves are provided in the middle of both sides of the support frame to provide space for diaphragm feeding.
[0008] Further, in the above-mentioned corrugated forming mechanism for a sensor diaphragm, three grooves with a "convex" cross-section are provided at intervals of 120° on the forming clamp seat.
[0009] Further, in the above-mentioned corrugated forming mechanism for a sensor diaphragm, there are three limiting and fixing components, including: a sliding block, a clamping block, and a diaphragm limiting block. The sliding block is a block structure with a "convex" cross-section, which matches the shape of the groove and is arranged in the groove. The clamping block is arranged above the sliding block, and the diaphragm limiting block is arranged at one end of the clamping block facing the center of the forming clamp seat. Due to the "convex" structure, the sliding block is limited and can only slide in the groove, improving stability.
[0010] Further, in the above-mentioned corrugated forming mechanism for a sensor diaphragm, the connecting end of the clamping block and the diaphragm limiting block protrudes towards the center of the forming clamp seat, and an anti-slip groove is provided on the protruding surface. The contact area between the clamping block and the diaphragm limiting block is reduced, thereby increasing the pressure, and an anti-slip groove is provided on the contact surface, improving the precise positioning and stability of the diaphragm.
[0011] Further, in the above-mentioned corrugated forming mechanism for a sensor diaphragm, the inner side of the diaphragm limiting block is an arc surface. The three diaphragm limiting blocks enclose the corrugated forming die to form a circle, and the height of the diaphragm limiting block is slightly higher than that of the corrugated forming die, thereby forming a diaphragm placement groove.
[0012] Further, in the above-mentioned sensor diaphragm corrugation forming mechanism, a guide sleeve is provided outside the guide post, which improves the accuracy of the downward pressing of the lower pressing head and the quality of the diaphragm corrugation forming.
[0013] Further, in the above-mentioned sensor diaphragm corrugation forming mechanism, the area of the downward pressing end surface of the forming head is equal to the area of the corrugated surface on the upper surface of the corrugation forming die, which conforms to the diaphragm size.
[0014] It can be seen from the above technical solutions that the present utility model has the following beneficial effects: The sensor diaphragm corrugation forming mechanism of the present utility model has a simple structure and convenient operation. The diaphragm limiting block wraps the corrugation forming die to form a diaphragm placement groove, with accurate positioning and high stability. The downward pressing mechanism improves the accuracy of the downward pressing of the lower pressing head through the setting of the guide post, and cooperates with the through hole in the middle of the lower pressing plate to press the forming head downward. The area of the downward pressing end surface of the forming head is equal to the area of the corrugated surface on the upper surface of the corrugation forming die, so that the forces received by the diaphragm in the plane direction when the diaphragm is pressed into corrugations are balanced, improving the quality of the corrugated diaphragm.

[0021] As Figure 2 A corrugated forming mechanism for a sensor diaphragm shown in the figure, the downward pressing mechanism 4 includes: guide columns 41, a lower pressing plate 42, a forming head 43, and a downward pressing head 44.

The downward pressing head 44 passes through the middle of the top plate 21 and is aligned with the through hole below.
[0022] Embodiment 2
[0023] Based on Embodiment 1, in this embodiment, as Figure 3 A corrugated forming mechanism for a sensor diaphragm shown in the figure, the forming clamp seat 31 is provided with three grooves 311 with a "convex" cross-section at intervals of 120°; there are three limiting and fixing components 33, including: a sliding block 331, a clamping block 332, and a diaphragm limiting block 333. The sliding block 331 is a block structure with a "convex" cross-section, which matches the shape of the groove 311 and is arranged in the groove 311. The clamping block 332 is arranged above the sliding block 331, and the diaphragm limiting block 333 is arranged at one end of the clamping block 332 towards the center of the forming clamp seat 31. Due to the "convex" structure, the sliding block 331 is limited and can only slide in the groove 311, improving stability.

The contact area between the clamping block 332 and the diaphragm limiting block 333 is reduced, thereby increasing the pressure, and the anti-slip groove 334 is provided on the contact surface, improving the precise positioning and stability of the diaphragm.
[0025] In this embodiment, the inner side of the diaphragm limiting block 333 is an arc surface. The three diaphragm limiting blocks 333 surround the corrugated forming die 32 to form a circle. The height of the diaphragm limiting block 333 is slightly higher than that of the corrugated forming die 32, thereby forming a diaphragm placement groove 34.

The area of the pressing end surface of the forming punch 43 when pressed down is equal to the area of the corrugated surface on the upper surface of the corrugated forming die 32, which conforms to the diaphragm size. This improves the accuracy of the pressing of the lower pressing head 44, and the forces received by the diaphragm in the plane direction when the corrugations are pressed out are balanced, improving the quality of the corrugated diaphragm.
