Description

TECHNICAL FIELD

[0001] The present application relates to the field of stamping processing, in particular to a punch slider assembly with reflective photoelectric alignment. BACKGROUND

[0002] Currently, the field of stamping processing widely uses punches with reflective photoelectric alignment assemblies. Such punches mainly achieve material clamping or stamping processing in the mold by pushing the slider, which can effectively improve production efficiency and processing precision. In actual application, the cooperation between the punch and the slider ensures the stability and consistency of the mold operation. However, as the use time increases, the friction and frequent movement between the punch and the slider cause the surface to gradually wear, especially in the embedded slider structure, the wear phenomenon is more significant.

[0003] The occurrence of wear problems directly affects the processing precision and product quality. In order to maintain high precision of processing, it is usually necessary to adjust the punch to compensate for the amount of wear. This adjustment process currently mainly relies on the reverse calculation of the product result size. However, this method has obvious shortcomings. First, the detection of product size depends on manual inspection or semi-automatic detection means, and the detection efficiency and accuracy cannot be completely guaranteed. Secondly, since the detection is carried out after the product is processed, once the product with poor size appears, it often causes a certain waste of materials and increase in cost, and the processing parameters cannot be timely discovered and adjusted.

[0004] The fundamental reason for the above-mentioned shortcomings lies in the limitations of the existing technology in wear compensation and real-time monitoring. Due to the lack of effective online monitoring and feedback mechanism, the accumulation of wear is often difficult to be discovered in time, which leads to adjustment lag, and further affects the production efficiency and product quality. In addition, the existing adjustment method relies too much on the size detection of the final product, and lacks comprehensive control and optimization of the processing process. CONTENT OF THE INVENTION

[0005] The purpose of the present application is to at least overcome at least one of the deficiencies of the prior art, and to provide a punch slider assembly with reflective photoelectric alignment, which can early warn the wear condition through more accurate wear monitoring, reduce the product failure rate, and reduce the production cost.

[0006] To achieve the above-mentioned purpose, the present application discloses a punch slider assembly with reflective photoelectric alignment, which comprises a punch and a slider opposite to the punch, wherein the punch is provided with a first working slope, and the slider is opposite to the first working slope and is matched with the first working slope through a second working slope, and when the punch goes down, the slider is pushed to move horizontally through the first working slope and the second working slope.

[0007] In order to realize compensation after wear, the upper part of the punch is fixed on a mounting seat, and a replaceable gasket is arranged between the mounting seat and the punch, and the overall length of the punch and the mounting seat is adjusted by replacing the gasket;

[0008] In order to realize alignment detection, an installation position is concavely arranged on the edge of the first working inclined surface of the punch, and a sensing assembly is detachably installed in the installation position, the sensing assembly comprising a body and a reflection type photoelectric sensor installed in the body and facing the second working inclined surface. Correspondingly, a working groove is concavely arranged on the second working inclined surface of the slider, and the groove bottom of the working groove is provided with a light-absorbing coating.

[0009] In some embodiments, a backing plate is detachably installed on the second inclined surface of the slider, and the service life of the slider is greatly improved by replacing the contact of the slider with the backing plate.

[0010] Compared with the prior art, the present application has at least one of the following beneficial effects:

[0011] 1. Accurate wear monitoring and early warning: by arranging a detachable sensing assembly on the first working inclined surface of the punch, real-time alignment detection is realized by using a reflection type photoelectric sensor, which can effectively monitor the wear between the punch and the slider, and give early warning to avoid the decline of machining precision.

[0012] 2. Improve production efficiency and reduce scrap rate: through accurate wear monitoring and real-time feedback, compensation adjustment can be made before wear occurs, thereby reducing the size of the poor caused by wear, reducing the scrap rate, and improving the production efficiency.

[0013] 3. Reduce production cost: through the design of replaceable gasket and backing plate on the slider, the corresponding parts can be replaced in time after wear occurs, without the need to replace the entire punch or slider, effectively prolonging the service life of the components and reducing maintenance and replacement costs.

[0014] 4. Enhance the durability of the slider: the detachable backing plate installed on the second working inclined surface of the slider not only provides additional protection and reduces wear, but also effectively improves the durability and service life of the slider, reducing the need for frequent replacement of the slider during production.

[0015] The above listed beneficial effects are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementation methods will be further disclosed in the embodiments or other description parts of the present application. BRIEF DESCRIPTION OF DRAWINGS

[0024] Referring to the accompanying drawings, Figs. 1-3 In the present embodiment, the punch slider assembly with reflective photoelectric alignment is composed of a punch 1, a slider 2, a sensing assembly 3, a mounting seat 4, a rigid metal gasket 5, and a backing plate 6, and the like. Each component part cooperates with the electronic detection system through precise mechanical connection to realize efficient wear monitoring and compensation, thereby significantly improving the precision and production efficiency of stamping processing.

[0025] The punch 1 is the core component of the assembly, made of high-strength alloy steel material to ensure its excellent wear resistance and strength during long-term stamping. One side of the punch 1 is provided with a first working slope, and the design angle of the slope is 15 degrees, which is precisely processed to ensure smooth and flawless surface. The slider 2 is made of wear-resistant steel, and its corresponding side is provided with a second working slope matched with the first working slope of the punch 1. The angle of the slope matches the punch 1 to ensure that the vertical pressure can be effectively converted into horizontal motion force when the punch 1 descends, pushing the slider 2 to slide smoothly. The precise matching of the two slopes ensures efficient and stable force transmission during stamping, reducing friction resistance and processing errors.

[0026] To compensate for wear, the upper part of the punch 1 is fixed on the mounting seat 4, which is made of aluminum alloy material with good strength and toughness. A plurality of rigid metal gaskets 5 are arranged between the punch 1 and the mounting seat 4. These gaskets 5 are made of high-strength steel plates with high rigidity and wear resistance, which can effectively maintain the precise fit between the punch 1 and the mounting seat 4 during stamping. When the punch 1 and the slider 2 are worn after long-term use, the overall length of the punch 1 and the mounting seat 4 can be adjusted by replacing the gaskets 5 to maintain the precise fit between the two, thereby compensating for wear caused by long-term use and ensuring the continuity and stability of the stamping process. Through this compensation mechanism, the service life of the assembly is extended, the maintenance process is simple, and the production cost is reduced.

[0027] The induction assembly 3 is installed in the mounting groove at the edge of the first working slope of the punch 1, which is concave by CNC precise processing to ensure the precise fixing position of the induction assembly 3. The induction assembly 3 includes a body and a pair of photoelectric sensors composed of high-sensitivity light-emitting diodes and photodiodes embedded in the body, facing the second working slope of the slider 2. The second working slope of the slider 2 is concave with a working groove, and the groove bottom is coated with a high-reflectivity light-absorbing coating to enhance the detection accuracy of the photoelectric sensor 3. When the punch 1 descends to push the slider 2 to move, the photoelectric sensor 3 emits a light beam and receives the reflected light signal from the second working slope of the slider 2. By monitoring the reflection of the light signal in real time, the system can accurately determine whether the relative position between the punch 1 and the slider 2 has deviated. Once the position deviation caused by wear is detected, the system will immediately issue a warning signal to prompt the operator to adjust or replace the gaskets 5 to prevent the decline of processing accuracy and product quality problems.

[0028] The second working slope of the sliding block 2 is also detachably mounted with a pad plate 6 made of hard alloy or ceramic composite material, which has extremely high wear resistance and impact resistance. The pad plate 6 is fixed in the working groove of the sliding block 2 by bolts and is designed as a modular structure for quick replacement. The pad plate 6 is mainly introduced to replace the direct contact between the sliding block 2 and the punch 1, further reducing the wear of the surface of the sliding block 2. When the frequent contact between the sliding block 2 and the punch 1 causes the surface of the pad plate 6 to wear, the normal working state of the sliding block 2 can be restored by replacing the pad plate 6 without replacing the entire sliding block 2, thereby significantly prolonging the service life of the sliding block 2 and reducing the maintenance cost.

[0029] In actual operation, the operator first installs the punch 1 on the mounting seat 4 and installs the rigid metal gasket 5 with appropriate thickness according to the specific stamping requirements. The mounting seat 4 is fixed with the punch 1 by bolts to ensure its stability. The sliding block 2 is installed at the corresponding position of the die and cooperates with the first working slope of the punch 1 through the second working slope. When the equipment starts to run, the punch 1 descends and converts the vertical pressure into horizontal movement force through the interaction of the first and second working slopes, pushing the sliding block 2 to slide smoothly. At the same time, the photoelectric sensor 3 in the sensing assembly 3 starts to work and continuously monitors the relative position between the punch 1 and the sliding block 2. When the sensing assembly 3 detects that the position deviation caused by wear reaches the preset threshold, the system immediately issues an alarm to prompt the operator to check and replace the corresponding gasket 5 or pad plate 6 to maintain the processing precision and product quality.

[0030] For example, in a factory specializing in the stamping production of automobile parts, after adopting the punch sliding block assembly of the embodiment, the product size stability of the production line is significantly improved through real-time monitoring and timely compensation for wear, and the scrap rate is reduced from the original 0.5% to 0.2%. At the same time, the design of the replaceable rigid metal gasket 5 and pad plate 6 makes the maintenance of the equipment more convenient, reduces the downtime of the equipment caused by the wear of the sliding block 2, thereby improving the overall production efficiency and reducing the production cost. Compared with the traditional punch sliding block assembly, the embodiment not only prolongs the service life of the assembly, but also realizes automatic wear monitoring and compensation through advanced photoelectric alignment technology, improving the intelligent level of the production line.

[0031] In summary, through detailed structural design and advanced reflective photoelectric alignment technology, the punch slider assembly successfully realizes the optimization of wear monitoring and compensation. Each component works together through precise mechanical cooperation and efficient electronic detection system, not only improving the machining precision and production efficiency, but also significantly improving the durability and maintenance convenience of the assembly through the design of rigid metal gasket 5 and high wear-resistant pad plate 6, further reducing the production cost. The technical scheme is suitable for various high-precision stamping processing environments, meeting the needs of modern manufacturing for efficient, stable and intelligent production equipment.

[0032] While exemplary embodiments of the present disclosure have been described, it will be understood by those skilled in the art that various changes and modifications can be made thereto without departing from the spirit and scope of the present disclosure in its essence. Therefore, all changes and modifications are intended to be included within the scope of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and equivalents thereof are included therein.
