Description

Technical Field

[0001] This utility model relates to the field of ductile iron processing technology, and in particular to a shot blasting device for processing ductile iron. Background Technology

[0002] Ductile iron, a high-strength cast iron material developed in the 1950s, boasts comprehensive properties approaching those of steel. Based on its superior performance, it has been successfully used to cast parts subject to complex stresses and requiring high strength, toughness, and wear resistance. However, traditional shot blasting systems for machining ductile iron parts typically combine shot blasters with roller conveyors. Shot blasting is best suited for strip-shaped or long ductile iron workpieces, such as pipes and long rods. When processing smaller workpieces, these smaller pieces are prone to getting stuck in the roller conveyor gaps or falling out, causing conveyor blockages, preventing proper shot blasting, and even leading to equipment malfunctions. Small workpieces are also susceptible to insufficient shot blasting due to roller obstruction and shot blaster layout limitations. Furthermore, traditional shot blasting systems cannot be flexibly adjusted according to workpiece size. Therefore, this paper proposes a shot blasting system for machining ductile iron to address these issues. Utility Model Content

[0003] The technical problem this invention aims to solve is to address the aforementioned technical deficiencies by providing a shot blasting device for processing ductile iron. This structure enables multi-dimensional shot blasting on the outer side of the workpiece, avoiding the blind spots of traditional devices. It can adapt to both larger and smaller workpieces, meeting the conveying and shot blasting needs of smaller workpieces, and overcoming the limitation of traditional devices being only suitable for strip-shaped ductile iron workpieces.

[0004] The technical solution adopted by this utility model is as follows: A shot blasting device for processing ductile iron is provided, including a shot blasting channel. The device is characterized by: two conveying mechanisms arranged within the shot blasting channel; the left-end conveying mechanism includes two conveyor belts; the two conveyor belts are aligned end-to-end, with the rear conveyor belt located at the right end of the front conveyor belt; stop bars are installed on the left side of both conveyor belts, with the front stop bar lower than the rear stop bar; the right-end conveying mechanism and the left-end conveying mechanism are symmetrical and have the same structure; six shot blasters are arranged within the shot blasting channel; two shot blasters are located at the upper and lower ends of the front of the shot blasting channel; the other four shot blasters are located at the four corners of the shot blasting channel, with the upper two shot blasters located at the front of the shot blasting channel and the lower two shot blasters located at the rear of the shot blasting channel; and an adjusting device for adjusting the right-end conveying mechanism is also included.

[0005] To further optimize this technical solution, an adjustment device for a shot blasting apparatus used for processing ductile iron includes two electric push rods installed at the right end of the shot blasting channel; the output ends of the two electric push rods are fixedly connected to two conveyor belts at the right end.

[0006] To further optimize this technical solution, a support is fixedly connected to the lower end of the conveyor belt at the left end of a shot blasting device for processing ductile iron; a movable frame is fixedly connected to the lower end of the conveyor belt at the right end, and a movable wheel is provided at the lower end of the movable frame.

[0007] To further optimize this technical solution, a shot blasting device for processing ductile iron also includes a base for supporting the shot blasting channel.

[0008] To further optimize this technical solution, a shot blasting device for processing ductile iron has mounting columns for installing dust curtains above both ends of the shot blasting channel.

[0009] To further optimize this technical solution, a chain conveyor is proposed as the conveyor belt for a shot blasting device used for processing ductile iron.

[0010] Compared with traditional shot blasting devices for processing ductile iron, the advantages of this invention are as follows:

[0011] 1. The installation of conveyor belts and shot blasting equipment allows for shot blasting of the upper and lower end faces of the workpiece, the upper and side surfaces of the workpiece, and the outer side of the workpiece.

[0012] 2. The structure of the rear stop bar and conveyor belt is designed to blast the lower left and lower right corners of the workpiece, resulting in more thorough shot blasting. Continuous shot blasting can be performed via the conveyor belt.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1-4 As shown, a shot blasting device for processing ductile iron includes a shot blasting channel 1. The device is characterized by: two conveying mechanisms within the shot blasting channel 1; the left-end conveying mechanism includes two conveyor belts 2; the two conveyor belts 2 are aligned end-to-end, with the rear conveyor belt 2 located at the right end of the front conveyor belt 2; both conveyor belts 2 have stop bars 3 installed on their left sides, with the front stop bar 3 lower than the rear stop bar 3; the right-end conveying mechanism and the left-end conveying mechanism are symmetrical and have the same structure; six shot blasters 4 are provided within the shot blasting channel 1; two shot blasters 4 are located at the upper and lower ends of the front of the shot blasting channel 1; the other four shot blasters 4 are located at the four corners of the shot blasting channel 1, with the upper... The two shot blasters 4 on the front are located at the front of the shot blasting channel 1, and the two shot blasters 4 below are located at the rear of the shot blasting channel 1; it also includes an adjustment device for adjusting the right-end conveyor mechanism; the adjustment device includes two electric push rods 5 installed at the right end of the shot blasting channel 1; the output ends of the two electric push rods 5 are fixedly connected to the two conveyor belts 2 at the right end; a bracket 6 is fixedly connected to the lower end of the left-end conveyor belt 2; a movable frame 7 is fixedly connected to the lower end of the right-end conveyor belt 2, and a movable wheel 8 is provided at the lower end of the movable frame 7; it also includes a base 9 for supporting the shot blasting channel 1; mounting columns 10 for installing dust curtains are provided above both ends of the shot blasting channel 1; the conveyor belt 2 is a chain conveyor.

[0021] In use, some ductile iron workpieces are placed on the two front conveyor belts 2. The two conveyor belts 2 transport the workpieces, and the workpieces move as follows: Figure 3 As shown, the workpiece first corresponds to the shot blasters 4 at both ends downwards. The shot blasters 4 at both ends shot blast the upper and lower end faces of the workpiece. At the same time, the two inclined shot blasters 4 at the top shot blast the upper part and the side of the workpiece. When the shot blasting is completed, the part in contact with the conveyor belt 2 and the part blocked by the stop bar 3 cannot be shot blasted sufficiently. The workpiece will move to the two conveyor belts 2 at the rear. At this time, the position of the two conveyor belts 2 at the rear and the workpiece changes. As a result, the two inclined shot blasters 4 at the bottom shot blast the parts on the left and right sides of the lower end of the workpiece that have not been shot blasted sufficiently. At the same time, the position of the stop bar 3 changes. The shot blasters 4 shot blast the parts on the left and right sides of the workpiece that have not been shot blasted sufficiently. Thus, the outer side of the workpiece is shot blasted sufficiently, and the shot blasting is more thorough.

[0022] The structure of the rear stop bar 3 and the conveyor belt 2 is such that the parts that are not fully shot blasted are the lower left and lower right corners of the workpiece, which correspond to the inclined shot blaster 4 for shot blasting, so that the shot blasting is more thorough and can be used for continuous shot blasting through the conveyor belt 2.

[0023] When the workpiece is large or small, the electric push rod 5 can be activated, which will drive the right-end conveyor mechanism to move and change the distance between the left and right conveyor belts 2. This allows for easy adjustment according to the size of the workpiece, making it convenient to perform shot blasting on workpieces of different sizes. Traditional shot blasting devices are mostly roller conveyors, which are suitable for conveying strip-shaped ductile iron workpieces. However, if small workpieces are being processed, they are prone to jamming or falling during transport, making them inconvenient for polishing.

[0024] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0025] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
