Description

Technical Field

[0001] This utility model belongs to the technical field of hardware tool processing equipment, specifically referring to a shot blasting device for tool and pliers processing. Background Technology

[0002] As an important category of hardware tools, the manufacturing process of pliers involves multiple steps, including metal cutting, forming, heat treatment, and surface treatment. The specific processing flow includes: forging the pliers body, milling, heat treatment, and surface treatment. In the surface treatment stage, shot blasting is typically used as the main processing equipment. High-speed shot impacts the workpiece surface, effectively removing oxide scale and burrs, while also achieving surface strengthening. During shot blasting, the shot undergoes two changes: some fragments break due to impact, while others retain their original intact shape.

[0003] First, when processing mixtures of whole pellets, pellet fragments, and ferromagnetic impurities, traditional single-layer screen separation systems suffer from low separation efficiency, failing to achieve precise grading and screening of materials with different particle sizes. This results in insufficient purity of the recovered pellets, severely impacting their subsequent reuse. Second, when removing magnetic impurities from pellet mixtures, existing magnetic separators generally employ a fixed installation structure. While this design ensures equipment stability, it requires complex disassembly for routine maintenance, significantly increasing the difficulty and time cost of maintenance. Utility Model Content

[0029] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0030] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0031] like Figures 1-7As shown, in some embodiments, a shot blasting device for tool pliers processing has a housing 1 as its main support structure. A screening mechanism 3 is installed at the discharge port of the housing 1. This mechanism adopts a composite multi-layer structure design, in which a separation plate 31, a screening plate 32, and a waste collection plate 33 are arranged sequentially from top to bottom to form a complete grading and processing system.

[0032] Specifically: the separation plate 31 has multiple separation holes 312 evenly arranged in an array on its surface. These separation holes 312 are used to separate the workpiece after shot blasting from the used shot. The screening plate 32 has a second surrounding plate 321 as an overall support frame, and multiple screening holes 322 are also set on its surface. These screening holes 322 are used to screen out qualified shot. Specifically, qualified shot is left on the screening plate 32, while waste slag falls through the screening holes 322 to the waste slag collection plate 33, realizing the recycling of shot.

[0033] In particular, multiple positioning grooves 36 are machined on the side of the second enclosure 321. These positioning grooves 36 are connected to the iron removal mechanism 4 and are used to remove ferromagnetic impurities generated during the processing.

[0034] Specifically, the iron removal mechanism 4 includes a guide baffle 41 installed at an inclined angle and a removable and replaceable magnetic plate 43. The guide baffle 41 is carefully designed and installed directly above the magnetic plate 43, a configuration with a clear protective purpose. When shot falls from a height, the inclined guide baffle 41 effectively alters the trajectory of the shot, preventing it from directly impacting the surface of the magnetic plate 43 below. This design avoids direct impact damage to the magnetic plate 43 and also prevents weakening of the adsorption force due to impact, thus ensuring that the magnetic plate 43 maintains optimal iron removal efficiency. Furthermore, the removable magnetic plate 43 allows for quick installation or removal as needed. This modular design greatly simplifies the equipment maintenance process, enabling convenient maintenance and efficient replacement of the iron removal mechanism 4.

[0035] The specific operation process in this embodiment is as follows:

[0036] After the workpiece is shot blasted inside the housing 1, the mixture falls into the screening mechanism 3;

[0037] At the separation plate 31, after vibration treatment, the workpiece is left on the upper part of the separation plate 31, and the clean workpiece is output. The mixture of shot and residue falls onto the screening plate 32 through the separation hole 312.

[0038] The mixture of pellets and residues is screened through sieve 322 to obtain qualified pellets. During this process, magnetic impurities in the pellets are adsorbed by magnet plate 43 to improve the purity of the pellets.

[0039] Subsequently, the residue falls through the screening hole 322 to the waste residue collection plate 33, from which it is discharged.

[0040] Through the layered screening mechanism 3, combined with the iron removal mechanism 4, efficient separation and recycling of workpieces, qualified shot, waste residue and magnetic impurities are achieved, significantly improving production efficiency and product quality, and enabling the recycling of shot.

[0041] Furthermore, in some embodiments, a vibration motor 5 is additionally installed on the side of the screening mechanism 3. This vibration motor 5 generates mechanical vibration through electric drive and transmits this vibration to the connected screening mechanism 3, thereby producing a continuous and stable vibration effect for the entire screening mechanism 3. This vibration design can effectively improve screening efficiency, ensure that the material after shot blasting is fully screened, and reduce the occurrence of material blockage.

[0042] Furthermore, in some embodiments, the screening mechanism 3 also includes a limiting module, which includes a limiting sleeve 34 and a limiting rod 35. Specifically, the limiting sleeve 34 is installed on the upper edge of the screening plate 32 and the upper edge of the waste collection plate 33; correspondingly, the limiting rod 35 is installed at the bottom support position of the separation plate 31 and the bottom support position of the screening plate 32, respectively.

[0043] This limiting structure design ensures that the functional plates maintain a precise relative position under high-speed vibration and impact loads, effectively preventing misalignment, displacement or loosening of the plates due to long-term use, thereby ensuring the working stability and long-term reliability of the entire screening process.

[0044] Furthermore, in some embodiments, a first surrounding plate 311 is provided on the outer periphery of the separation plate 31. The first surrounding plate 311 is arranged along the outer edge of the separation plate 31 to prevent material from falling during the screening process. A workpiece discharge port 313 is provided at the end of the first surrounding plate 311, through which the screened workpieces enter the workpiece collection box.

[0045] Furthermore, in some embodiments, a shot discharge port 323 is also designed at the end of the second enclosure 321. The pure shot after screening will be output smoothly and orderly through the shot discharge port 323. This design ensures the smooth discharge of the shot and also helps to improve the working efficiency and stability of the entire shot blasting device.

[0046] Furthermore, in some embodiments, the waste collection plate 33 includes a third enclosure plate 331 and a waste discharge port 332. The third enclosure plate 331 is also located on the outer periphery of the waste collection plate 33, and its sides are evenly distributed with multiple positioning grooves 36. These positioning grooves 36 are connected to the iron removal mechanism 4 in a manner that ensures no loosening occurs during shot blasting. The waste discharge port 332 is also located at the end of the third enclosure plate 331 to facilitate automatic sliding of the waste.

[0047] Furthermore, in some embodiments, the iron removal mechanism 4 also includes a structurally stable fixing plate 42, which is positioned midway between the guide baffle 41 and the magnet plate 43, serving a crucial connecting and supporting role. Specifically, both ends of the fixing plate 42 are connected to the positioning groove 36 via an embedded connection, and elastic gaskets are provided at the connection between the fixing plate 42 and the positioning groove 36, providing a buffering effect. This connection method ensures both installation accuracy and overall structural stability.

[0048] Of particular note is the unique toothed structure of the magnetic plate 43. This design not only increases the adsorption area and improves the iron removal efficiency, but its serrated edges also better capture and collect fine iron filings generated during shot blasting, thus significantly improving the overall iron removal effect and performance of the device. The magnetic plate 43 can be made of a permanent magnet or an electromagnet.

[0049] Furthermore, in some embodiments, the aperture size of the separation hole 312 in the screening mechanism 3 is designed to be significantly larger than that of the screening hole 322. This structural design ensures that during the screening process, larger particles of shot are intercepted by the screening hole 322 after passing through the separation hole 312 and enter the recycling system, while smaller particles of waste enter the waste collection plate 33 through the screening hole 322. This achieves graded screening and recycling of shot, improves shot blasting efficiency, and reduces abrasive consumption.

[0050] Furthermore, in some embodiments, a shot blaster 2 is installed at the top center of the housing 1. The shot blaster 2 is used to spray steel shot onto the surface of the workpiece. The internal space of the housing 1 is provided with a track turning part 12. The track turning part 12 adopts a continuously circulating conveyor belt structure, which can drive the tool pliers workpiece to be processed to continuously turn over during the shot blasting process, ensuring that all surfaces of the workpiece can be uniformly shot blasted.

[0051] In addition, a sealing cover plate 11 is specially designed and installed at the material outlet of the shell 1. The sealing cover plate 11 adopts an openable and closable structure, which can maintain the sealing of the shell 1 during shot blasting and facilitate the removal of the workpiece after the processing is completed.

[0052] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0053] The embodiments have been described above, and such description is not restrictive. The figures shown are only one embodiment, and the actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
