Description

Technical Field

[0001] This utility model relates to the processing of automotive one-way valve diaphragms, and more particularly to a multi-station processing and forming device for automotive one-way valve diaphragms. Background Technology

[0002] A one-way valve diaphragm in automobiles is a device installed in the oil or air circuits to control the unidirectional flow of fluids or gases. When fluid or gas flows from one side of the diaphragm to the other, the one-way valve diaphragm automatically opens; conversely, when the fluid or gas flows in the opposite direction, the valve diaphragm closes to prevent backflow. This device is widely used in automobiles.

[0003] Current automotive one-way valve diaphragm production processes involve first designing the diaphragm's structure and material selection based on specifications and performance requirements. Then, molding equipment is used to press the raw material into a single diaphragm sheet. The diaphragm is then manually trimmed from this sheet, completing the diaphragm forming process. Currently, to improve processing speed, a stamping machine is used as the forming structure in the automotive one-way valve diaphragm production process. However, this single-structure forming equipment can only eject a single diaphragm from the raw material. Multiple stamping and continuous ejection can cause the diaphragm to adhere to the scrap material, still requiring manual trimming. This results in low forming efficiency and poor ejection / extraction quality. Therefore, it is necessary to design a multi-station, high-quality automotive one-way valve diaphragm processing and forming device. Utility Model Content

[0004] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a multi-station processing and forming device for automotive one-way valve diaphragms, which realizes the purpose of multi-station processing and forming of automotive one-way valve diaphragms to produce high-quality valve diaphragms.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A multi-station processing and forming device for automotive one-way valve diaphragms includes a frame body. An upper mold is provided on the upper side of the frame body, and a lower mold that cooperates with the upper mold is provided on the moving end of the frame body. The upper mold includes a limiting seat fixed to the stamping end of the frame body, a plurality of valve diaphragm seats provided at the lower end of the limiting seat, and an inner diameter block provided in the middle of the valve diaphragm seats. The lower mold includes an outer cutting seat opposite to the limiting seat. A plurality of valve diaphragm grooves that cooperate with the valve diaphragm seats are opened on the top of the outer cutting seat. An inner diameter hole is opened in the middle of the valve diaphragm grooves. A splitting assembly is provided through the periphery of the upper mold. A separation plate is provided at the lower end of the splitting assembly and penetrates the valve diaphragm seat for cutting the outer edge scrap of the valve diaphragm.

[0007] Preferably, the valve diaphragm seat is matched with the valve diaphragm groove, the inner diameter block can pass through the inner diameter hole, and the inner diameter hole extends to the lower end of the lower mold.

[0008] Preferably, an outer tangent ring is fixedly provided on the top of the outer tangent seat outside each valve diaphragm groove, and the top of the outer tangent ring is provided with a sharp part. The size of the outer tangent ring is the same as the outer diameter of the valve diaphragm.

[0009] Preferably, the separating component includes a hydraulic cylinder that penetrates the upper mold. The lower end of the hydraulic cylinder is provided with a telescopic end. A spring is sleeved on the outer side of the lower end of the hydraulic cylinder at the telescopic end, and the spring is fixedly connected to the separating plate. Both ends of the spring are fixed with rubber seats for elastic connection with the upper mold and the separating plate.

[0010] Preferably, the separation plate has an opening in the middle, and several abutments are provided on the lower end of the separation plate around the opening.

[0011] Preferably, the bottom of the separation plate is provided with a pressing plate, which is a pressure-sensitive pad, and the bottom of the pressing plate is provided with a plurality of suction cups.

[0012] Preferably, a vibration assembly is provided through the separation plate, the vibration assembly including a vibration motor, and a protective pad is provided at the end of the vibration motor.

[0013] Compared with existing technologies, the multi-station processing and forming device for automotive one-way valve diaphragms provided by this utility model can process multiple automotive valve diaphragms at once, effectively and quickly separating the valve diaphragm from waste materials. The structure of the upper mold limiting seat, valve diaphragm seat, and inner diameter block facilitates cooperation with the outer cutting seat valve diaphragm groove and inner diameter hole in the lower mold, allowing for simultaneous cleaning of the inner and outer diameters of the entire valve diaphragm raw material. The multiple valve diaphragm seats and grooves enable the processing and forming device to cut multiple automotive one-way valve diaphragms after demolding, improving the processing adequacy and speed of the valve diaphragm, reducing processing steps, and lowering processing costs.

[0014] The combined use of the upper die opening component and the separation plate can limit the stamped outer diameter waste material, allowing the waste material at the outer diameter edge to be fully separated from multiple valve membranes, improving the processing quality of the forming device. Then, through the use of the lower end pressing plate and multiple suction cups of the separation plate, the outer diameter waste material can be limited on the separation plate when the upper and lower dies open, separating it from the valve membrane product in the valve membrane groove, realizing the separate feeding of valve membranes and waste material, facilitating product separation, reducing waste screening steps, and providing favorable conditions for high-efficiency processing of the forming device.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be described in more detail below with reference to the accompanying drawings. Note: The described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0027] As attached Figure 1 To be continued Figure 4 As shown, the multi-station processing and forming device for automotive one-way valve diaphragms provided in the embodiment of this utility model can be used as a punching and drawing structure when processing the entire valve diaphragm raw material. First, the guide rail moving end in the middle of the frame body 1 is used to move the lower die 12 to the lower part of the upper die 11 and distribute it opposite to the upper die 11. Then, the material punching technology of the existing punching machine is applied, and the upper die 11 punches the lower die 12 and punches the valve diaphragm raw material above the lower die 12 to realize the inner diameter removal of the entire valve diaphragm raw material. To facilitate the simultaneous stamping of multiple automotive one-way valve diaphragms, the upper die 11 can include a limiting seat 111 fixed to the stamping end of the frame body 1. Multiple valve diaphragm seats 112 are provided at the lower end of the limiting seat 111, and an inner diameter block 113 is fixed in the middle of each valve diaphragm seat 112. When the upper die 11 and the lower die 12 are stamping, the valve diaphragm seat 112 will be squeezed against the lower die 12 to limit the processing of the valve diaphragm. The inner diameter block 113 will penetrate the lower die 12 to remove the inner diameter scrap in the middle of the valve diaphragm, thereby realizing the inner diameter processing of multiple one-way valve diaphragms. Next, the lower mold 12 includes an outer cutting seat 121 opposite to the limiting seat 111. Multiple valve diaphragm grooves 122 are formed on the top of the outer cutting seat 121 to cooperate with the valve diaphragm seat 112. An inner diameter hole 123 is formed in the middle of the valve diaphragm groove 122. When the upper mold 11 presses down on the lower mold 12, the valve diaphragm seat 112 is pressed into the valve diaphragm material and fits against the valve diaphragm groove 122, limiting the valve diaphragm. The inner diameter block 113 penetrates the lower mold 12 through the inner diameter hole 123, cutting off the waste material inside the valve diaphragm, thus achieving inner diameter cutting of the entire valve diaphragm material. Then, by using a prying component 2 that penetrates around the upper mold 11, and a separation plate 3 at the lower end of the prying component 2, which penetrates the valve diaphragm seat 112, it is convenient to cut the outer edge of the entire valve diaphragm material from the material, facilitating the separate collection of scraps from different locations, thus promoting environmental protection and recycling.

[0028] Among them, such as Figures 4 to 6 As shown, in the structural design of the upper mold 11 and the lower mold 12, the valve diaphragm seat 112 and the valve diaphragm groove 122 are set to the same shape, so that the valve diaphragm seat 112 and the valve diaphragm groove 122 are matched to limit the inner and outer sides of the valve diaphragm. Then, the outer diameter of the inner diameter block 113 is set to be the same as or slightly smaller than the inner diameter of the inner diameter hole 123, so that the inner diameter block 113 can penetrate the inner diameter hole 123. The lower end of the inner diameter hole 123 is extended to the lower end of the lower mold 12, so that the inner diameter hole 123 can be opened through the lower mold 12. The inner diameter scrap is removed from the lower mold 12 as the inner diameter block 113 is punched, avoiding the accumulation of waste material. This is beneficial to the continuous processing of the processing and forming equipment, increases the degree of removal of the valve diaphragm inner diameter, and improves the processing quality of the processing and forming equipment.

[0029] To more quickly remove waste material from the outer diameter of the valve diaphragm, such as Figure 4As shown, an outer cutting ring 4 can be fixed on the top of the outer cutting seat 121 on the outside of each valve diaphragm groove 122, and a sharp part 41 is provided on the top of the outer cutting ring 4. The size of the outer cutting ring 4 is the same as the outer diameter of the valve diaphragm. When the upper die 11 presses down, the limiting seat 111 on the top of the upper die 11 will press against each outer cutting ring 4 on the top of the outer cutting seat 121, so that the outer cutting ring 4 cuts the outer diameter of multiple valve diaphragms at the same time. This makes it convenient for the processing and forming equipment to remove the edges of the entire valve diaphragm material at the same time, and to process the inner and outer diameters at the same time. This realizes the multi-station large-scale cutting of valve diaphragms, increases the diversity and fullness of the processing and forming equipment, and improves the processing efficiency of the processing and forming equipment.

[0030] In some embodiments, such as Figure 3 and 7 As shown, in order to facilitate the rapid separation of the valve diaphragm from the waste material, such as Figure 5 and 6 As shown, the disassembly assembly 2 can be driven by a hydraulic cylinder. The hydraulic cylinder includes a main body end and a telescopic end 21. The main body end passes through the upper mold 11, and the telescopic end 21 is located at the lower end of the hydraulic cylinder. A spring 22 is then installed at the lower end of the hydraulic cylinder. The spring 22 is sleeved on the outside of the telescopic end 21 of the hydraulic cylinder, and the lower end of the spring 22 is fixedly connected to the separation plate 3. The rubber seats 23 at both ends of the spring 22 facilitate the elastic connection between the spring 22 and the upper mold 11 and the separation plate 3. When the component 2 is used, the processing and forming device can use the extension of the hydraulic cylinder to press down the waste material according to the state of the entire valve membrane raw material, so as to fully separate the waste material from the valve membrane. Then, the hydraulic cylinder is retracted, and the spring 22 drives the separation plate 3 to press on the waste material. Then, through the reset of the upper mold 11, the upper mold 11 is first separated from the valve membrane, and the valve membrane is retained in the valve membrane groove 122. Then, through the continuous rise and reset of the upper mold 11, the spring 22 can be slowly reset to the initial position, preventing the waste material from shifting, increasing the stability of waste material removal, and bringing favorable conditions for the neat processing of the valve membrane and waste material collection.

[0031] Among them, such as Figure 3 and 6 As shown, in some embodiments, to facilitate the cleaning of waste material from the outer diameter of the valve diaphragm, a through-hole 34 can be opened in the middle of the separation plate 3, through which multiple valve diaphragm seats 112 can pass. Then, several abutments 33 are set on the periphery of the through-hole 34 at the lower end of the separation plate 3. The abutments 33 are set to limit the edge of the waste material by the separation plate 3, preventing the waste material from sticking to the valve diaphragm. When the separation plate 3 is in use, the through-hole 34 facilitates the passage of the upper mold 11 through the separation plate 3, and it can be used directly with the lower mold 12. The separation plate 3 can limit the waste material cut by the processing and forming equipment, realizing the separation of the entire valve diaphragm raw material and the outer diameter waste material, increasing the waste material separation structure on the processing and forming equipment, and facilitating the use of the separation plate 3 in conjunction with the outer cutting seat 121.

[0032] Furthermore, to facilitate the separate collection of outer diameter waste and valve diaphragm, and to improve the processing efficiency of the processing and forming equipment, such as... Figure 7 As shown, a pressing plate 31 can be set at the bottom of the separating plate 3. Several suction cups 32 are set at the bottom of the pressing plate 31. The pressing plate 31 can use pressure-sensitive gaskets. Pressure-sensitive gaskets, also known as pressure-sensitive pads, are gaskets composed of pressure-sensitive adhesive and PS foam sealing gaskets. Its principle mainly relies on the combined action of pressure-sensitive adhesive and PS foam sealing gaskets. When subjected to external pressure, the pressure-sensitive adhesive will generate corresponding adhesive force according to the magnitude of the pressure, so that the gasket is tightly adhered to the surface of the lower mold 12. Because this type of gasket can achieve adhesion according to factors such as ambient temperature and bottle cap pressure.

[0033] When the valve membrane material is pressed down by the separation plate 3, the suction cup 32 adheres to the valve membrane material. The suction cup 32 deforms and discharges the gas inside. The material is sucked onto the separation plate 3. With the assistance of the pressure-sensitive pad pressing plate 31, the material can be adhered to the separation plate 3. When the upper mold 11 opens from the lower mold 12, the separation plate 3 can separate the outer diameter waste material from multiple valve membrane products.

[0034] To facilitate the rapid collection of waste, such as Figure 3 As shown, a vibration assembly 5 can be installed on the separation plate 3. The vibration assembly 5 can use a vibration motor 51 as the driving structure. A protective pad 52 is then installed at the end of the vibration motor 51 to provide favorable conditions for the separation plate 3 to be used in the stamping process of the upper mold 11 and the lower mold 12. Through the use of the vibration assembly 5, the outer diameter waste material can be automatically and quickly removed from the separation plate 3, realizing the separate collection of valve membrane and waste material, and providing favorable conditions for the processing of the next valve membrane raw material.

[0035] Of course, the above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
