Description

Technical Field

[0001] The invention belongs to the technical field of mechatronics, and in particular relates to a pressure detection device for simulating hydraulic powder forming in multiple environments. Background Art

[0002] Powder forming presses can produce high-precision, multi-step pressed products at one time, and have a wide range of applications, high production efficiency and material utilization. They are now widely used in the pressing of various metal, ceramic, bakelite and other powder products, and the shapes of the pressed products are becoming more and more complex.

[0003] In the traditional powder molding process, applying pressure is a key step to achieve powder molding. The magnitude and duration of pressure depends on the shape, size and material properties of the desired molded part. Usually, a higher pressure is applied to ensure that the powder mixture is fully compacted and molded. While applying pressure, the powder mixture in the mold will be uniformly compressed to form a part of the desired shape. After a certain period of pressurization, the pressure is released and the mold is removed to obtain a molded part.

[0004] The powder forming presses currently on the market lack pressure detection devices and are unable to detect the extrusion force on the powder, thereby being unable to adjust the applied pressure according to different materials. In addition, powder dust will be generated during use, which can easily cause a poor environment inside the workshop, and the dust inside the device is difficult to clean, thereby reducing the efficiency of the device.

[0005] Hydraulic powder forming can control the forming process by adjusting pressure and speed to reduce the generation of pores and defects, thereby achieving higher forming accuracy and consistency, improving forming quality and product performance. Therefore, compared with traditional powder forming, hydraulic powder forming has the advantages of higher forming accuracy, efficiency and quality, wider application range, and more material saving.

[0006] Patent No. CN216430139U discloses a "hydraulic component detection device", which effectively solves the shortcoming of low detection efficiency through specific technical structure settings. However, in actual use, devices with similar structures still have many defects. For example, the overall structure is relatively simple, and most of them use an open structure to detect hydraulic components. During the detection operation, it is not possible to simulate high or low temperature environments, resulting in a small sample size when the device detects hydraulic components, and the authenticity is poor; at the same time, during the detection operation, it does not have the function of guiding and collecting the leaked hydraulic oil, resulting in the device being unable to continuously detect the hydraulic components, so it is necessary to design a hydraulic component pressure detection device.

[0007] The utility invention patent with patent number CN220615051U discloses a pressure detection device for a powder forming press, which relates to the technical field of detection devices. The detection device includes an equipment installation base plate, a structural support column installed on the upper end of the equipment installation base plate, and a detection table installed on the upper end of the equipment installation base plate; a pressure detection component is arranged inside the detection table, an internal cleaning component is arranged on the upper end of the detection table, an anti-dust protection component is arranged on the outer side of the structural support column, and a detection top plate is fixedly connected to the upper end of the structural support column, and a pressure driving device is arranged on the upper end of the detection top plate. The detection device generates air pressure by squeezing a telescopic hose through a pressure detection component, and then squeezes the inside of the air storage cylinder through a first push piston, thereby increasing the air pressure to push the second push piston to move inside the detection oil pump cylinder, so that the pressure can be displayed. However, in this invention patent, the environment of powder forming is not simulated, and it is difficult to determine the optimal pressure size under different environmental conditions.

[0008] Therefore, a hydraulic powder detection device capable of simulating a variety of environmental conditions is needed to determine the size of the optimal pressure under different environmental conditions. Summary of the invention

[0031] Specifically, the environmental simulation module includes a main box 2, which includes a square entrance at the front end, and a hole on the surface that matches the size of the internal parts is opened to facilitate the installation of the hydraulic motor module and the pressure detection module.

[0033] Specifically, the pressure detection module includes a pressure detection bottom shell 6 arranged at the bottom of the inner side of the main box body 2 and a pressure detection top shell 10 arranged on the pressure detection bottom shell 6. A detection space is formed between the two shells. A detection structure bottom plate 23 is arranged in the detection space. A group of telescopic hoses 24 are arranged on the detection structure bottom plate 23. A pressure detection display assembly is arranged on the side. The pressure detection display assembly includes an air storage cylinder 21, a pushing piston and a detection oil pump cylinder connected in sequence.

[0034] A hydraulic mechanism installation slot 26 is provided in the middle of the pressure detection top housing 10, and the hydraulic motor module is placed in the hydraulic mechanism installation slot 26; the bottom of the hydraulic mechanism installation slot 26 contacts the top of a group of telescopic hoses 24,

[0035] The number of the telescopic hoses 24 is five, namely, a first telescopic hose 241, a second telescopic hose 242, a third telescopic hose 243, a fourth telescopic hose 244, and a fifth telescopic hose 245; see the attached drawings for specific arrangement. Figure 5 .

[0036] There are two groups of pressure detection and display components, which are respectively arranged on both sides of the detection structure bottom plate 23; the left pressure detection and display component includes a left air reservoir 211, a left push piston 201 and a left detection oil pump cylinder 191; the right pressure detection and display component includes a right air reservoir 212, a left push piston 202 and a right detection oil pump cylinder 192. The air reservoir is threadedly connected to the corresponding push piston; and the left air reservoir 211 and the right air reservoir 212 are both connected to five telescopic hoses.

[0037] Specifically, the hydraulic motor module includes a hydraulic module bottom mounting block 15 and a hydraulic module top driving block 16, which are supported by four support rods and provided with a powder holder 8.

The bottom of the hydraulic module bottom mounting block 15 is provided with a hydraulic power drive device 14 in the powder filling space. The output end of the hydraulic power drive device 14 is connected to a hydraulic pusher through a hydraulic pressure main rod 17. The hydraulic pusher 3 is a sac-like structure, and a protective cover 18 is provided on the outer side thereof. The protective cover 18 is in close contact with the inner wall of the powder holder 8, so that the hydraulic pusher can apply pressure to the powder under the drive of the hydraulic power drive device 14.

[0038] Specifically, the waste collection module includes a pull-out residual material storage piece 12, which is arranged in the main box 2 on one side of the pressure detection module; the pressure detection top shell 10 scraper 28, the scraper 28 is moved left and right through a transmission mechanism to clean the dust scattered on the pressure detection top shell 10 into the residual material storage piece 12.

[0039] The transmission mechanism includes a rotating screw 25 and a driving motor 27 . The rotating screw 25 is rotatably disposed on the pressure detection top housing 10 and is connected to the output shaft of the driving motor 27 . The scraper 28 is threadably connected to the rotating screw 25 .

[0040] When the interior of the main box 2 is overheated or overcooled, the thermal imaging camera lens 4 will capture the abnormality inside the box and send a termination signal to stop the environment simulation module from working to protect the entire machine.

[0041] The working process of this embodiment is as follows:

[0042] First, the target model and material powder are dropped from the top into the filling space in the powder filling fixture 8, and the powder filling fixture 8 is installed in the hydraulic mechanism composed of a hydraulic power drive device 14, a hydraulic module top drive block 16, a hydraulic pressure main rod 17, and a hydraulic push plate protective cover 18, and the hydraulic mechanism is installed to the pressure detection module through the hydraulic module bottom mounting block 15 and the hydraulic mechanism mounting groove 26.

[0044] When detecting the hydraulic pressure, the pressure is transmitted to the pressure detection top shell 10 through the bottom mounting block 15 of the hydraulic module to squeeze the five telescopic hoses 24 to generate the effect of air pressure, and then the corresponding groove positioning structure and the protrusion positioning structure and the matching structure with the pressure detection top shell 10 can play the effect of fixing the bottom plate 23 of the detection structure, thereby increasing the stability of its internal structure; through the setting of the left air storage cylinder 211, the right air storage cylinder 212 and the left pushing piston 201 and the left pushing piston 202, the air pressure generated by squeezing the telescopic hose 24 can be further amplified, so that it can be transmitted to the left detection oil pump cylinder 191 and the right detection oil pump cylinder 192 through the left pushing piston 201 and the right pushing piston 202, and then the scale lines set on the surface can be used to facilitate reading, thereby further improving the accuracy and convenience of pressure detection.

[0045] At the same time, by driving the motor 27 to control the rotation of the rotating screw 25, after the hydraulic motor module is removed, the scraper 28 can be driven to move, and the dust scattered on the pressure detection top shell 10 can be brought into the residual material storage part 12; the powder dust diffusion caused by the extrusion inside the device is protected, the dust is reduced from floating in the air, the protection effect on the operator is improved, and the practicality of the device is further improved.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
