Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chip removal machine, more particularly, it is a kind of chip removal machine that is convenient to clean. BACKGROUND

[0002] In the field of modern mechanical processing, chip removal machine as a key auxiliary equipment in the process of metal cutting, its performance directly affects the production efficiency and workshop environment quality, however, under the existing technical conditions, chip removal machine in practical application faces significant functional barriers, specifically, when the iron chips generated by the machine tool are compressed or accumulated for a long time, often form a volume expansion, loose structure of iron chip group, this special form of iron chip group is difficult to establish stable friction on the smooth chain plate surface of traditional design, resulting in iron chip often appears in the conveying process, accumulation and even reverse rolling phenomenon, in order to solve this technical problem, the industry generally adopts the method of setting vertical or inclined push rod structure on the chain plate surface, using the mechanical engagement force formed between the push rod and the iron chip group to improve the conveying effect, this design indeed improves the conveying capacity of the chip removal machine for the expanded iron chip group to a certain extent, so that even the iron chip group with large volume and irregular shape can be effectively pushed forward, improving the processing capacity and continuous operation reliability of the chip removal system.

[0003] However, the improved design of setting push rod on the chain plate solves the problem of conveying efficiency, but at the same time, it also causes a series of new use and maintenance problems. The push rod structure not only enhances the conveying capacity, but also forms a large number of uneven surfaces and hidden spaces. These areas are prone to accumulate a mixture of small iron chips, cutting fluid and metal dust. These residual substances will gradually harden over time, not only reducing the effective height and engagement capacity of the push rod, but also possibly increasing the running resistance of the chain plate, accelerating equipment wear and tear. More troublesome is that conventional cleaning methods such as flushing or scraping are inefficient in the face of such complex structures. Maintenance personnel need to invest a lot of time and effort to complete thorough cleaning, and sometimes even need to disassemble part of the chain plate assembly to access the deep dirt. This cleaning difficulty not only reduces the daily maintenance efficiency of the equipment, increases downtime and maintenance cost, but also easily leads to incomplete cleaning, which affects the long-term operation stability and service life of the equipment.

[0017] (Three) beneficial effects

[0018] Compared with the prior art, the present application provides a convenient-to-clean chip removal machine, which has the following beneficial effects:

[0019] The technical innovation of the convenient cleaning chip removal machine lies in the intelligent telescopic push iron structure design, which is different from the fixed installation of the push rod structure on the traditional chip removal machine. The design adopts a controllable telescopic push iron mechanism, and the automatic extension and retraction of the push iron component are realized through a hydraulic lifting system. In the normal conveying state, when the chip group passes, the lifting mechanism will push the steel belt to rise, and the telescopic rod on the chain plate will automatically extend and penetrate into the chip group to form meshing, thereby generating a pushing force. This design solves the problem of slipping and accumulation of traditional chip removal machines when facing expanded chip groups, ensuring the continuity and stability of the conveying process. When maintenance is needed, the operator only needs to control the hydraulic system to reset the steel belt, and all telescopic rods will automatically retract into the chain plate under the action of the spring force, so that the surface of the chain plate returns to a flat state. This component storage mechanism eliminates obstacles on the surface of the chain plate, simplifies the cleaning process, improves the cleaning efficiency, and allows maintenance personnel to directly flush or scrape the flat chain plate surface to easily remove attached small chips and cutting fluid mixtures without additional disassembly steps, greatly reducing maintenance time and labor intensity. This intelligent telescopic push iron structure ensures efficient conveying while achieving convenient cleaning.

[0020] The design introduces a lubrication system that automatically releases an appropriate amount of lubricating oil when the round head component on the chain plate contacts and slides with the steel belt, reducing the friction and wear between moving parts. This intelligent lubrication system is also equipped with an adjustable oil discharge control device. The operator can adjust the spring balance point by simply rotating according to actual working conditions, thereby controlling the release amount of lubricating oil per time, ensuring sufficient lubrication while avoiding waste and secondary pollution caused by excessive oil use. In addition, the chip removal machine is also equipped with a steel belt tensioning mechanism. Through the combination design of fixed wheels and follow-up wheels, combined with a spring buffer system, the steel belt tension can be adjusted. When the position of the steel belt changes, the tensioning mechanism can automatically compensate for the length change, always keeping the steel belt in a proper tension state, ensuring the accurate control and reliable operation of the lifting system. The combination of these multiple cooperative mechanisms improves the conveying efficiency and cleaning convenience of the chip removal machine, prolongs the service life of the equipment, reduces maintenance costs, and provides a new solution for chip removal processing in the metal processing industry.

[0035] When the chain 218 rotates, the plurality of chain plates 219 are driven to rotate. When the round head 223 is not attached to the steel belt 24, the plurality of telescopic rods 220 are retracted into the chain plate 219 under the action of the top spring 224. When the hydraulic cylinder 21 drives the lifting plate 22 to move upward, the steel belt 24 is pushed to move upward. When the chain plate 219 drives the round head 223 to move to the position of the lifted steel belt 24, the synchronous frame 221 is pushed to drive the plurality of telescopic rods 220 to move upward, and then the plurality of telescopic rods 220 extend out of the chain plate 219 and are inserted into the iron filings group. Therefore, the force for moving the iron filings group is increased, so that the situation of slipping is avoided. When cleaning is needed after the conveying is completed, the hydraulic cylinder 21 is only needed to move downward to reset the steel belt 24. Under the action of the top spring 224, the telescopic rod 220 is retracted into the chain plate 219. Therefore, the plurality of telescopic rods 220 do not affect the cleaning of the chain plate 219, and the convenience of cleaning is improved.

[0036] When the hydraulic cylinder 21 drives the lifting plate 22 to move upward, the position of the steel belt 24 relative to the lifting plate 22 does not change because the middle position of the upper end of the steel belt 24 is fixedly connected to the middle position of the lifting plate 22. Then, the steel belt 24 moves upward. The plurality of chain plates 219 are driven to move circularly by the movement of the chain 218, and the round head 223 is pressed against the flow groove 29. When the round head 223 continuously moves and moves along the lifting rod 27, the lifting rod 27 is pressed downward, so that the seal between the oil outlet disc 210 and the control pipe 25 is released. Because the oil inlet pipe 217 is connected to the external oil inlet equipment, a little lubricating oil flows out, so that the friction of the round head 223 sliding along the flow groove 29 is reduced, and the convenience of sliding is improved. When the degree of opening of the lifting rod 27 needs to be adjusted, the compression amount of the return spring 214 is changed by rotating the threaded pipe 216 which is screwed to the threaded sleeve 215, so that the elastic force of the round head 223 is changed. Because the round head 223 is also subjected to the elastic force of the top spring 224, when the elastic force of the return spring 214 increases, the degree of opening of the return spring 214 decreases, so that the oil outlet amount of each time is reduced, so that the corresponding situation can be adapted.

[0037] The tensioning mechanism comprises a plurality of fixed wheels 31 and a plurality of follower wheels 32 clamped on the steel belt 24, and the plurality of fixed wheels 31 and the plurality of follower wheels 32 are arranged at equal intervals respectively, the plurality of fixed wheels 31 are rotatably connected on a fixed frame 33 respectively, the plurality of follower wheels 32 are rotatably connected on a follower frame 34 respectively, a plurality of guide rods 35 are installed on the fixed frame 33, a plurality of guide sleeves 36 are installed on the follower frame 34, the guide rods 35 are slidably connected on the guide sleeves 36, a plurality of springs 37 are installed at equal intervals between the fixed frame 33 and the follower frame 34, and a middle disc 38 is installed at the middle position of each spring 37 respectively, a plurality of adjusting bolts 39 are threadedly connected on the fixed frame 33, a fixed spring 310 is sleeved and installed on the adjusting bolt 39, and the adjusting bolt 39 abuts against the middle disc 38.

[0038] When the hydraulic cylinder 21 drives the steel belt 24 to move upward, since the middle position of the steel belt 24 is fixedly connected on the jacking plate 22, the middle position of the upper end of the steel belt 24 will not move, thereby driving the steel belts 24 on both sides to move, at this time, since the steel belt 24 is engaged on the plurality of fixed wheels 31 and the plurality of follower wheels 32 respectively, and the fixed wheels 31 are rotatably connected on the fixed frame 33, and the follower wheels 32 are rotatably connected on the follower frame 34, and the two are positioned by the guide rods 35 and the guide sleeves 36, at this time, the springs 37 will be compressed, thereby reducing the distance between the fixed frame 33 and the follower frame 34, and further adjusting the length of the upper end of the steel belt 24, when it is needed to adjust the elastic force of the springs 37 with the same displacement, the adjusting bolt 39 is rotated to make the adjusting bolt 39 abut against the middle disc 38, and then the spring 37 is subjected to a thrust force, thereby changing the elastic force of the spring 37 at the same position, and further improving the tensioning force of the steel belt 24.

[0039] In all the schemes mentioned above, the connection between two components can be selected according to the actual situation, such as welding, bolt and nut cooperation connection, bolt or screw connection or other known connection mode, which will not be described one by one, and in the above, when it is mentioned that it is fixedly connected, it is preferred to be welded, although the embodiments of the application have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the application, and the scope of the application is defined by the appended claims and their equivalents.
