Description

Technical Field

[0001] The utility model relates to the field of powder metallurgy, in particular to a material shoe with a sensor. Background Art

[0002] In the powder metallurgy industry, the production of cemented carbide or cermet CNC inserts typically follows a production process consisting of powder compacting, sintering, and finishing. Powder compacting is a key process in the production of CNC cermet inserts, and the feed shoe, as an important tool in the powder compacting press, plays a crucial role in the filling process.

[0003] Traditional material shoe designs are relatively simple, typically consisting of a square box and a circular guide tube. However, as the pressing process continues, the raw material in the barrel, tube, and shoe gradually decreases. When the raw material decreases to a certain level, it leads to packing instability, which in turn affects the weight fluctuation of each compact and the density distribution at the tool tip. After sintering, this uneven density distribution can lead to serious deformation problems.

[0004] Especially for TPA mechanical presses, unstable fillers can endanger mold safety. Some companies have previously attempted to add photoelectric sensors to the material barrel to monitor the remaining material level. However, because raw materials often contain black components such as graphite powder, a layer of black material forms on the inner wall of the transparent plastic barrel over time, blocking the sensor's light and preventing it from accurately detecting the remaining material level. Therefore, this solution has not been ideal in practical applications. Utility Model Content

[0005] The purpose of the utility model is to provide a material shoe with a sensor to solve the problem that the prior art cannot accurately sense the remaining situation of the raw materials.

[0006] The utility model is realized by adopting the following technical scheme: a material shoe with a sensor, characterized in that it includes a material shoe, a material guide tube and a material level detection sensor, the material guide tube and the material level detection sensor are both inserted into the material shoe, and the material level detection sensor is located on one side of the material guide tube.

[0007] Furthermore, the material level detection sensor includes a sensor and a sensor sleeve, and the sensor is arranged in the sensor sleeve.

[0008] Furthermore, a mounting plate is provided on the material shoe, and the material guide tube and the material level detection sensor are mounted on the material shoe through the mounting plate.

[0009] Furthermore, the mounting plate is provided with a threaded hole, and the sensor sleeve is provided with an external thread, and the external thread and the threaded hole cooperate with each other.

[0010] Furthermore, the material level detection sensor adopts a 6.5mm proximity sensor with a PNP normally open signal output mode. The sensor line is connected to the input point in the press PLC to achieve signal communication with the press.

[0011] Furthermore, when the head of the material level detection sensor contacts the raw material, the sensor will be turned on and provide a high-level signal to the press. The press determines through the PLC that there is material in the material shoe and continues production; when the material level is lower than the position of the material level detection sensor, the material level detection sensor cannot detect the raw material, and the press will stop production due to no signal received.

[0012] Furthermore, the material guiding pipe and the material level detection sensor are arranged in parallel.

[0013] The beneficial effects of the sensor-equipped material shoe described in the utility model include:

[0014] Improved packing stability: By redesigning the shoe structure and adding a material level sensor to the shoe, this utility model can monitor the remaining material in the shoe in real time. When the material level falls below the sensor, the press immediately stops pressing, thus avoiding packing instability caused by insufficient material. This helps improve the weight stability of each compact and the uniformity of the density distribution at the tool tip.

[0015] Ensuring mold safety: By accurately sensing the remaining material, the utility model prevents the press from continuing to operate when the material is insufficient, thereby preventing equipment failures such as mold damage caused by the upper punch being under pressure or damage to the press mold frame. This helps reduce production costs and improve production efficiency.

[0016] Strong adaptability: The material shoe structure of this utility model is rationally designed, the material guide tube is height-adjustable, and both the sensor access port and the fixing sleeve are threaded, allowing the sensor's detection height to be adjusted at will. This design allows the utility model to adapt to presses of different specifications and models, increasing its scope of application and flexibility.

[0017] Improve product quality: By real-time monitoring and precise control of the remaining amount of raw materials, this utility model helps to improve the quality and stability of products. It avoids the problem of post-sintering deformation caused by unstable fillers, making the products more in line with company standards and customer needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0025] like Figure 1-3 As shown, a material shoe with a sensor includes a material shoe 1, a material guide tube 2 and a material level detection sensor 3. The material guide tube 2 and the material level detection sensor 3 are both inserted into the material shoe 1. A mounting plate 4 is also provided on the material shoe 1. The material guide tube 2 and the material level detection sensor 3 are mounted on the material shoe 1 through the mounting plate 4.

[0026] The mounting plate 4 is provided with a feed hole, the shape of which is the same as that of the material guide tube 2. The material guide tube 2 is inserted into the material shoe 1 through the feed hole. The mounting plate 4 is also provided with a sensor mounting hole, and the material level detection sensor 3 is inserted into the material shoe 1 through the sensor mounting hole.

[0027] The material level detection sensor 3 includes a sensor 31 and a sensor sleeve 32. The sensor 31 is arranged in the sensor sleeve 32. The outer side of the sensor sleeve 32 is provided with a thread, and the sensor mounting hole is provided with a corresponding thread, which facilitates the installation and height adjustment of the material level detection sensor 3.

[0028] Sensor 31 is a 6.5mm proximity sensor with a normally open (PNP) signal output. The sensor circuit is connected to an input point in the press's PLC, enabling signal communication with the press. When material contacts the sensor head, the sensor switches on and provides a high-level signal to the press. The press, through the PLC, determines that material is present in the shoe and continues production. If the material level falls below the sensor position, the sensor cannot detect the material, and the press stops production due to lack of signal reception.

[0029] By adjusting the installation height of the sensor, it can adapt to the filling height of different raw materials and ensure the stability and accuracy of the filling process.
