Description

Technical Field

[0001] The utility model relates to the technical field of iron chip separation, in particular to an iron chip separator with high-efficiency chip removal. Background Art

[0002] During the processing and forming of workpieces (such as screws, bolts, etc.), it is inevitable that some iron filings will be mixed in. If they fall directly into the collection bin, it will be difficult to clean up the iron filings. The remaining iron filings can easily scratch the thread surface and affect the quality of the bolts. Therefore, the iron filings must be separated and picked out from the workpiece.

[0003] For example, a chip separator disclosed in Chinese utility model CN202022436938.1 mainly comprises a preliminary separation section extending from a feeding platform, an auxiliary separation section located below the preliminary separation section, a chip dropping port formed between the preliminary separation section and the auxiliary separation section, and a chip collecting seat arranged below the preliminary separation section, the auxiliary separation section and the chip dropping port, wherein the preliminary separation section and the auxiliary separation section respectively have a plurality of screening rods and a dropping gap formed between the screening rods; therefore, the workpiece formed by the forming machine can be separated from the chips by the chip dropping port and the dropping gap during the process of passing through the separation zone. Not only is the structure simple, but the operation can also be used for workpieces of different sizes, thereby increasing the convenience of use.

[0004] Although the workpiece and iron chips are separated through the gap between the screening rods, during separation, due to the different sizes of iron chips and the entanglement of different iron chips, it is difficult for large-sized or multiple iron chips entangled with each other to fall on the screening rod. In addition, the separated iron chips and workpieces are oily, and a separate device is required for sedimentation and oil filtration, which requires secondary transportation and a long sedimentation time and occupies a large area, which is time-consuming and labor-intensive. At the same time, the traditional sedimentation oil filtration effect is poor, the separation rate is less than 50%, and the production cost is high. Utility Model Content

[0005] In view of this, the utility model provides an iron chip separator with high-efficiency chip removal to solve the above technical problems.

The chip removal device comprises a plurality of step-shaped screening rods arranged at the chip removal port, a plurality of conical screening rods arranged at the chip removal port, an oil leakage net arranged at the discharge port, and a chip blocking rod arranged between the chip removal port and the oil leakage net.

[0017] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0018] like Figure 1 to Figure 2 As shown, it is a schematic diagram of the structure of the iron chip separator with high efficiency chip removal provided by the utility model. The iron chip separator with high efficiency chip removal includes a device body 10, a material flow channel 20 arranged on the device body 10, and a chip removal device 30 arranged on the material flow channel 20. It can be imagined that the iron chip separator with high efficiency chip removal also includes some other functional modules such as oil leakage grooves, oscillation devices, etc., which are well known to those skilled in the art and will not be described one by one here.

[0019] The equipment body 10 is a main body part for supporting the above structures, and can be made of rigid materials such as stainless steel, alloy, cast iron, etc. to ensure its stability and reliability. The bottom of the equipment body 10 is connected to a vibration device, such as a vibration motor, so that the iron chips and the workpieces can jump in the chip removal device 30 and be separated by vibrating the equipment body 10.

[0020] The material flow channel 20 is an inclined flow channel for the movement of the workpiece, and includes a feed port 21 located on one side of the equipment body 10 , a discharge port 22 located on the other side of the equipment body 20 , and a chip removal port 23 located between the feed port 21 and the discharge port 22 .

[0021] The feed port 21 is located on one side of the equipment body 10 and is connected to the thread rolling machine or the discharge device of the previous process, and an oil leakage hole is provided at the feed port 21, so that when a workpiece that has been thread rolled, such as a screw, falls from above the feed port 21 into the material flow channel 20 and hits the material flow channel 20, part of the oil on the workpiece will flow out from the oil leakage hole to achieve preliminary degreasing.

[0022] The discharge port 22 is located in the logistics direction of the feed port 21, and the height of the discharge port 21 from the ground is smaller than the height of the feed port 21 from the ground, so that after the workpiece enters the material flow channel 20, it will slide from the feed port 21 to the discharge port 22 along the material flow channel 20 under the action of gravity.

[0023] The chip discharge port 23 is located between the feed port 21 and the discharge port 22, and is disposed adjacent to the discharge port 22, and the opening direction is perpendicular to the horizontal plane, so that when passing through the chip discharge port 23, the iron chips screened by the chip discharge device 30 fall from the chip discharge port 23 under the action of gravity. Correspondingly, a collecting box for collecting iron chips can also be disposed below the chip discharge port 23, which is an existing technology that can be thought of by those skilled in the art, so it will not be described in detail one by one here.

[0024] The chip removal device 30 includes a plurality of step-shaped screening rods 31 arranged at the chip removal port 23, a plurality of conical screening rods 32 arranged at the chip removal port 23, an oil leakage net 33 arranged at the discharge port 22, and a chip blocking rod 34 arranged between the chip removal port 23 and the oil leakage net 33.

[0025] The step-shaped screening rod 31 and the conical screening rod 32 are both arranged at intervals and in parallel on the chip removal port 23, and the axial direction of the rod body is consistent with the inclination direction of the material flow channel 20, and a gap is provided between adjacent rod bodies, so that when the material slides down along the rod body, the iron chips fall from the gap under the action of vibration, and the bolt with the screw head continues to slide down along the rod body. In this embodiment, the step-shaped screening rod 31 and the conical screening rod 32 are arranged in two layers at intervals and staggered, and the step-shaped screening rod 31 is located above the conical screening rod 32 to facilitate the sliding of the workpiece. In addition, the cross-sectional shape of the step-shaped screening rod 31 and the conical screening rod 32 can be circular or mutually interlocking polygons, and no specific limitation is made here. It can be imagined that the gap between the step-shaped screening rod 31 and the conical screening rod 32 can be adjusted according to the size of the workpiece for chip removal.

[0026] The step-shaped screening rod 31 is provided with a step at one end close to the chip blocking rod 34. Specifically, the end of the step-shaped screening rod 31 is directly smaller than the diameter of the rod body to form a step-like structure, thereby forming a larger gap for large-sized iron chips to fall.

[0027] The end of the conical screening rod 32 located near one end of the chip blocking rod 34 is a truncated cone structure, and the height of the truncated cone is consistent with the step length of the step-shaped screening rod 31, so as to increase the maximum gap between the two screening rods and facilitate the falling of large-sized iron chips. It can be imagined that in order to prevent the workpiece from falling therefrom, the screw head of the workpiece needs to be larger than the maximum gap there.

[0028] The oil leakage net 33 is arranged in the logistics direction of the chip blocking rod 34, and is an inclined mesh structure, which can be made of stainless steel, so that the workpiece after chip removal falls on the oil leakage net 33 and filters the oil under the action of gravity.

[0029] The axial direction of the chip guard rod 34 is perpendicular to the axial directions of the step-shaped screening rod 31 and the conical screening rod 32, and the height of the chip guard rod 34 is less than the height of the conical screening rod 32 located at the lower layer, so that the workpiece can slide along the rod body to the oil leakage net 33, and the falling iron chips will be blocked by the chip guard rod 34 and will not fall onto the oil leakage net 33 with the workpiece.

[0030] Compared with the prior art, the iron chip separator with high chip removal provided by the utility model increases the gap at the end by setting the step-shaped screening rod 31 and the conical screening rod 32, so that the iron chips with increased size can also fall from between the screening rods, and the workpiece is ejected and falls to the oil leakage net 33 due to the conical structure and vibration, thereby achieving the purpose of separation. At the same time, by setting the chip blocking rod 34, the falling iron chips are blocked from entering the oil leakage net 33, affecting the chip removal efficiency. Finally, by setting the oil leakage net 33, the workpiece after chip removal is deoiled to improve work efficiency.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
