Description

Technical Field

[0001] The present invention relates to the technical field of bolt production equipment, and in particular to a steel coil shot blasting equipment for producing bolts. Background Art

[0002] Castings (such as bolts) must be shot blasted during the processing process. This is not only to remove the oxide scale and sand on the surface of the casting, but also an indispensable preparatory process before the casting quality inspection.

[0003] The disclosure number of the existing disclosed technology is CN111168558A, which is a drum-type shot blasting machine, belonging to the technical field of shot blasting machines. A shot blasting machine (8) is fixed on the upper part of a shot blasting chamber (9), a drum (12) is fixedly installed inside a drum bracket (13), one side of the shot blasting chamber (9) is provided with an opening, the drum bracket (13) is rotatably provided at the opening of the shot blasting chamber (9), the drum bracket (13) is connected to a drum turning motor (14) for driving the drum to turn over, a drum rotating motor (22) for driving the drum (12) to rotate, and a sealing frame (35) that matches the shot blasting chamber (9) is also provided on the drum bracket (13). After the drum bracket (13) drives the drum (12) to turn over into the shot blasting chamber (9), the sealing frame (35) is fitted with one side of the opening of the shot blasting chamber (9) to achieve sealing of the shot blasting chamber (9). The present invention forms a sealed space by fitting the drum bracket to the shot blasting chamber, thereby improving the traditional sealing structure.

[0004] However, the above invention patent still has certain defects when used: due to its relatively single rolling direction during operation, it is easy to have problems such as a single throwing angle and a limited grinding area when throwing shot blasting, resulting in a decrease in the workpiece cleaning and processing efficiency, and the inability to reduce the actual cleaning dead angle of the workpiece. In addition, its single-station operation means that it takes a long time to remove the internal materials and add new materials and shot blasting before each operation, which leads to an extension of the overall operation time, is not conducive to rapid production processing operations, and causes a decrease in operating efficiency. In addition, during the shot blasting operation, due to the vibration of the machine body and the collision of the shot blasting with the inner wall of the device, and the workpiece and the shot blasting, a large noise will be generated. The mixture of multiple noises will cause the overall operating noise to increase significantly, affecting the physical and mental health of the operators. Summary of the Invention

[0052] Working principle: In actual use, personnel can first put the shots and bolts needed to be used into the shot blasting chamber 5 and the bolt chamber 8 from the feed ports 3 at different positions, which is convenient for subsequent addition and use. In addition, the shots will pass through the dust collector 4 during the falling process to remove the debris and dust mixed therein, thereby improving the subsequent use effect of the shot blasting. Then, the operation of the second brake motor 23 can drive the adjusting disk 17 to rotate, so that the upper processing cylinder 10 can be accurately moved to the bottom of the partition 7, so that the docking tube 9 at its top can be accurately aligned with the shot blasting tube 35 and the bolt tube 36, to ensure the accuracy of subsequent feeding and prevent material leakage. In order to ensure the accuracy of docking, it can be installed on the surface of the above structure. Install the displacement sensor and the corresponding infrared transmitter and infrared receiver. Through the induction of the sensing equipment, it can ensure that the above components are docked. Then, the motor 12 is operated to realize the winding of the connecting rope 14. At this time, the sealing plate 34 will be driven to open, so that the materials in the shot blasting tube 35 and the bolt tube 36 can fall into the interior of the processing ball 30. After the shot blasting and bolt addition are completed, the motor 12 is reversed to cover the sealing plate 34 to the surface position of the processing ball 30 again to achieve its sealing operation. In addition, the sealing plate 34 and the surface position of the processing ball 30 are both equipped with electromagnets for enhancing the stability of the seal. The adsorption of the two is achieved by energizing to avoid separation during high-speed rotation, which causes leakage of internal materials. Then, the second brake motor 2 is used. 3 can move the processing cylinder 10 loaded with materials to the top of the first brake motor 21. At this time, the new processing cylinder 10 can be moved to the material to add materials to realize the addition of materials, which is convenient for subsequent direct rotation and use. Moreover, the processing cylinder 10 that has been processed before can be moved to the other end accordingly, which is convenient for personnel to remove the internal bolts and shot blasting. The overall operation process fluency is greatly improved, the pause time between steps is short, and it is no longer necessary to spend a long time to unload and load materials. The multi-station structure can effectively improve the operation efficiency. Then, in the subsequent grinding operation, first, the docking plate 22 on the top of the first brake motor 21 and the docking groove 2 at the bottom of the processing cylinder 10 are connected. 6 is clamped, and then the operation of the first brake motor 21 can drive the processing cylinder 10 to run at a high speed, so that the internal shot blasting can collide with the bolt to realize the cleaning and grinding operation of the bolt and remove burrs. After the operation of the first brake motor 21 is completed, the operation of the third brake motor 24 can drive the internal processing ball 30 to rotate at high speed in different directions, so that the internal bolt and shot blasting can fully contact again, thereby improving the processing efficiency. In the two high-speed rotation and grinding processes in different directions, the first grinding ball 31 and the second grinding ball 33 inside it will also contact the bolt during the rotation process, thereby improving the actual processing and grinding effect again, improving the overall processing effect, and in the operation process,The first sound insulation layer 2, the second sound insulation layer 15, and the third sound insulation layer 16 can absorb and weaken the noise generated by the impact between the shot and the device, and between the shot and the object, thereby reducing the noise. On this basis, the processing cylinder 10 will be restricted by the limiting ring 11 and the carrying ring 37 to prevent it from deflecting during high-speed rotation, thereby reducing the noise generated by random rotation and vibration, and improving the overall noise reduction effect. The device as a whole has the advantages of excellent shock and noise reduction performance, high operating efficiency, and good processing effect.
