Description

Technical Field

[0001] This utility model relates to the field of steel casting cleaning technology, specifically a polishing and cleaning machine for steel castings. Background Technology

[0002] Cast steel parts refer to parts or blanks obtained by pouring molten steel into a pre-prepared mold cavity through the casting process, followed by cooling, solidification, cleaning, and heat treatment. They are one of the important structural components in the industrial field and are widely used in industries such as machinery manufacturing, automobiles, aerospace, rail transportation, and energy equipment.

[0003] In the processing of cast steel parts, the surface needs to be polished and cleaned by shot blasting machine. However, in long-term production, the shot material is fatigued and broken due to high-speed impact on the workpiece and shot blasting equipment. The broken shot material has a smaller particle size and irregular shape, which not only leads to a decrease in blasting kinetic energy and cleaning efficiency, but may also cause scratches or precision damage to the workpiece surface due to the inclusion of sharp fragments. At the same time, the accumulation of broken shot material can easily cause equipment failures such as blockage of shot material conveying pipeline and failure of dynamic balance of shot blasting impeller, which seriously affects production efficiency and processing quality. Therefore, a polishing and cleaning machine for cast steel parts is proposed to solve the above-mentioned problems. Utility Model Content

It offers advantages such as filtering broken shot blasting material, improving overall production efficiency and processing quality. This solves the problem that while shot blasting is necessary for polishing and cleaning cast steel parts during processing, long-term production often results in shot fragmentation due to fatigue caused by high-speed impact on the workpiece and shot blasting components. The resulting fragmented shot has a smaller particle size and irregular shape, leading to decreased blasting kinetic energy and cleaning efficiency. Furthermore, it may cause scratches or precision damage to the workpiece surface due to the inclusion of sharp fragments. Simultaneously, the accumulation of broken shot can easily cause blockages in the shot conveying pipeline and equipment malfunctions such as impeller dynamic imbalance in the shot blasting machine, severely impacting production efficiency and processing quality.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the embodiments, by Figure 1-4The present invention discloses a polishing and cleaning machine for cast steel parts. The present invention includes a cleaning machine body 1 and a material conveyor 2 connected to the cleaning machine body 1. Two baffle plates 3 are symmetrically fixedly installed on the inner wall of the cleaning machine body 1 to limit shot blasting splash. A perforated screen plate 5 is fixedly connected to the cleaning machine body 1 through an elastic support member 4. The perforated screen plate 5 can vibrate vertically. A power component 6 is provided inside the cleaning machine body 1 to drive the perforated screen plate 5 to vibrate. A material conveying box 7 connected to the material conveyor 2 is embedded in the cleaning machine body 1. A detachable collection component 8 is provided at the bottom of the cleaning machine body 1.

[0028] The cleaning machine body 1 includes a shot blasting device located on top of it, and the shot blasting device is connected to the material conveyor 2. The filtered shot will be transported back to the inside of the cleaning machine body 1 through the material conveyor 2 to facilitate subsequent shot blasting operations.

[0029] By setting a baffle plate 3, a perforated screen plate 5 with elastic support, a power component 6, a material conveying box 7, and a collection component 8 in the body of the cleaning machine, the splashing during shot blasting and the recycling of shot are realized. The vertical vibration shot blasting of the perforated screen plate 5 separates and collects impurities. The structure is reasonably designed and the functions are coordinated, which meets the needs of automated operation for polishing and cleaning of cast steel parts.

[0030] The protective door 9 is hinged to the front opening edge of the cleaning machine body 1. The cleaning machine body 1 is equipped with an observation window to check the internal operation. The edge of the protective door 9 is fitted with a sealing strip to ensure the airtightness when closed. The perforated conveyor belt is horizontally set in the upper part of the interior of the cleaning machine body 1. Its two ends are supported by rollers. The rollers are driven to rotate by a motor installed on the outside of the cleaning machine body. The perforated conveyor belt has screen holes evenly distributed on its surface. The cast steel parts 10 to be polished are placed on the conveyor belt at intervals and move with the conveyor belt to the shot blasting operation area.

[0031] The perforated conveyor belt enables continuous transport of the cast steel parts to be polished, allowing the parts to be shot blasted during movement. This improves the continuity and automation of the cleaning operation. The perforated design allows some of the shot to pass through the conveyor belt and fall down, reducing the accumulation of shot on the perforated conveyor belt.

[0032] The elastic support component 4 includes a connecting frame 41 fixedly connected to the inside of the cleaning machine body 1 and a connecting spring 42 vertically fixedly connected to the top of the connecting frame 41. The top of the connecting spring 42 is fixedly connected to the bottom surface of the perforated screening plate 5.

[0033] The elastic support component 4 provides elastic support for the perforated screen plate 5 through the cooperation of the connecting frame 41 and the connecting spring 42, so that the screen plate can stably vibrate vertically under the drive of the power component 6. The buffering effect of the spring can reduce the rigid impact of vibration on the cleaning machine body 1, extend the service life of the equipment, and at the same time ensure the effective separation of shot blasting and cast steel parts during the vibration of the screen plate.

[0034] Among them, there are multiple elastic support components 4, which are arranged in a rectangular array at the bottom of the perforated sieve plate 5, and the top of the perforated sieve plate 5 is fixedly connected to a splash guard 11.

[0035] The rectangular array distribution of multiple elastic support components 4 ensures the stability of the perforated screen plate 5 during vibration, avoids tilting or displacement caused by single-point force, and enables the screen plate to vibrate evenly to improve the shot blasting separation effect.

[0036] The power assembly 6 includes a drive motor 61 installed on the outside of the cleaning machine body 1, a transmission shaft 62 fixedly connected to the output shaft of the drive motor 61 via a coupling, and several eccentric wheels 63 fixed on the transmission shaft 62. The outer edge of the eccentric wheels 63 is in contact with the bottom of the perforated screening plate 5.

[0037] The centrifugal force characteristic of the eccentric wheel is used to make the perforated screen plate 5 vibrate vertically. The structure is simple and the transmission is reliable. It can provide a stable vibration driving force and ensure that the vibration frequency and amplitude of the screen plate meet the requirements of shot blasting screening.

[0038] The inner wall of the feed box 7 is inclined to guide the directional flow of shot blasting, and a push block is fixedly connected to the bottom inner wall of the feed box 7.

[0039] The inclined inner wall design of the feed box 7 utilizes gravity to achieve directional conveying of shot blasting, reducing the accumulation and blockage of shot blasting within the feed box.

[0040] The collection component 8 includes a guide frame 81 fixed to the bottom of the cleaning machine body 1, a collection box 82 slidably inserted into the guide frame 81, and a weighing sensor provided in the guide frame 81. The opening of the collection box 82 is directly opposite the falling trajectory of the perforated screening plate 5.

[0041] The collection component 8 is slidably connected to the collection box 82 via the guide frame 81, which facilitates regular cleaning and replacement of the collection box 82 by the staff and improves the ease of operation. The setting of the weighing sensor can monitor the weight of the collected material in real time, providing data support for the equipment control system to realize the discharge or early warning function, ensuring the intelligence and efficiency of the collection process. The design of the opening facing the falling trajectory of the screening plate ensures the accurate collection of shot blasting and impurities.

[0042] Working principle:

[0043] The cast steel part 10 to be polished is conveyed to the shot blasting area of ​​the cleaning machine body 1 by a perforated conveyor belt for polishing and cleaning. During the cleaning process, the shot will fall onto the surface of the perforated screen plate 5 through the baffle plate 3.

[0044] The drive motor 61 drives the eccentric wheel 63 to rotate through the transmission shaft 62. The outer edge of the eccentric wheel 63 contacts the bottom of the perforated screen plate 5. The extrusion force generated by centrifugal force drives the perforated screen plate 5 to vibrate vertically, thereby performing the shot blasting and filtering operation.

[0045] After filtration, the shot blasting material will pass through the conveyor box 7 and then through the material conveyor 2 back into the inner side of the cleaning machine body 1, facilitating subsequent shot blasting operations. Defective shot blasting material or some impurities will enter the collection box 82, be collected by the collection box 82, and be centrally processed.
