Description

Technical Field

[0001] This utility model relates to the technical field of cutting fluid injection devices, and in particular to a directional cutting fluid injection device for a band saw. Background Technology

[0002] A band saw is a machine tool that uses a ring-shaped saw band for cutting. Its working principle is that the high-speed rotation or reciprocating motion of the saw blade causes the saw teeth to contact the workpiece, thereby achieving sawing. The motor drives the saw wheel to rotate, and the saw blade mounted on the saw wheel moves accordingly. The saw teeth on the saw blade generate cutting force on the workpiece to complete the cutting. However, the saw blade generates a lot of heat during the cutting process, so a cutting fluid spray device is needed to cool the tool and the workpiece. In addition, the coolant has good lubrication function, which can reduce tool wear and extend tool life.

[0003] Existing cutting fluid injection devices generally include a reservoir, a pump, a shaped hose, and a directional nozzle. When the pump is started, it draws cutting fluid and delivers it to the directional nozzle through the shaped hose. The directional nozzle then sprays the cutting fluid onto the desired cooling position of the tool. The shaped hose is a flexible pipe with shape retention capability, which allows the spray position of the directional nozzle to be adjusted arbitrarily and maintain stable operation. After the cutting fluid is injected into the reservoir, the pump can be started to spray the cutting fluid through the directional nozzle.

[0004] In actual use, due to the working characteristics of band saws, the aforementioned spraying device is often used to cut long strip-shaped workpieces. Because the contact cutting position is relatively long and the spray cooling range of a single spray pipe is limited, the cooling and lubrication effect of the cutting fluid spraying device is reduced, which in turn leads to a reduction in the service life of the cutting tool. Therefore, a cutting fluid directional spraying device for band saws is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cutting fluid directional injection device for band saws, which aims to improve the problem that the limited spray cooling range of a single cutting fluid injection device affects the cooling and lubrication effect when machining long strip-shaped workpieces.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a directional injection device for cutting fluid of a band saw, comprising a storage tank, a pump fixedly connected to the right side surface of the storage tank, a shaped hose fixedly connected to the right output end of the pump, a spray housing fixedly connected to the bottom outlet end of the shaped hose, several partitions fixedly connected inside the spray housing, the partitions dividing the interior of the spray housing into multiple spray channels, a guide sleeve fixedly connected inside the spray channel, a spray pipe fixedly connected to the left side of the guide sleeve, a limit ring rotatably connected to the bottom surface of the spray channel, and an adjustment unit provided above the limit ring for rotating and adjusting the position of the limit ring.

[0007] As a further description of the above technical solution:

[0008] The outer wall of the right end of the guide sleeve is fixed to the inner wall of the injection channel.

[0009] As a further description of the above technical solution:

[0010] The limiting ring is fitted onto the outside of the injection pipe.

[0011] As a further description of the above technical solution:

[0012] The adjustment unit includes a rectangular cylinder, which is fixedly connected to the upper end of the limiting ring. A threaded cylinder is fixedly connected to the upper surface of the spray housing. A screw is threadedly connected inside the threaded cylinder. A knob is fixedly connected to the upper end of the screw, and a rectangular rod is fixedly connected to the bottom end of the screw.

[0013] As a further description of the above technical solution:

[0014] The upper surface of the spray housing has a through hole, the bottom end of the rectangular rod passes through the through hole, and the bottom end of the rectangular rod is inserted into the interior of the rectangular cylinder.

[0015] As a further description of the above technical solution:

[0016] The outer side of the knob has anti-slip texture.

[0017] As a further description of the above technical solution:

[0018] A tapered strip is fixedly connected to the right end of the partition.

[0019] As a further description of the above technical solution:

[0020] The guide sleeve has a chamfer on its right side.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, through the combination of the set baffle, spray channel, guide sleeve, spray pipe, limiting and adjusting unit, the cutting fluid entering the spray housing can be divided into multiple streams for spraying, thereby increasing the spray cooling range to adapt to long strip-shaped workpieces.

The structure is simple and the operation is convenient.

[0023] 2.

[0032] 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.

[0033] Reference Figures 1-2 This utility model provides an embodiment of a cutting fluid directional injection device for a band saw, including a storage tank 1. A pump 2 is fixedly connected to the right side surface of the storage tank 1. A shaped hose 3 is fixedly connected to the right output end of the pump 2. The shaped hose 3 achieves the function of fixing its shape after bending through an internal reinforcing structure (such as a metal coil or plastic spiral) or special material. A spray housing 4 is fixedly connected to the bottom outlet end of the shaped hose 3. When the pump 2 is started, the cutting fluid inside the storage tank 1 can be drawn and transported to the inside of the spray housing 4 through the shaped hose 3. The above structure is a prior art in this field and will not be described in detail here. Several partitions 5 are fixedly connected inside the spray housing 4. The partitions 5 divide the inside of the spray housing 4 into multiple spray channels 6. When the cutting fluid enters the inside of the spray housing 4, it can be sprayed out in multiple streams through the spray channels 6.

[0034] Reference Figures 2-4 A guide sleeve 7 is fixedly connected inside the injection channel 6. The outer wall of the right end of the guide sleeve 7 is fitted and fixed to the inner wall of the injection channel 6. The cutting fluid flowing into the injection channel 6 can completely enter the corresponding guide sleeve 7. A spray pipe 8 is fixedly connected to the left side of the guide sleeve 7. After the cutting fluid enters the guide sleeve 7, it can flow in the spray pipe 8. At the same time, the guide sleeve 7 is made of flexible rubber, so that the connection with the spray pipe 8 can be bent, thereby allowing the spray pipe 8 to rotate and adjust relative to the guide sleeve 7 and maintain connection stability.

[0035] A limiting ring 9 is rotatably connected to the bottom surface of the injection channel 6. The limiting ring 9 is sleeved on the outside of the injection pipe 8. The limiting ring 9 can limit and support the injection pipe 8, so that the injection pipe 8 can be used stably. At the same time, since the limiting ring 9 can rotate relative to the injection channel 6, when the limiting ring 9 rotates, it can drive the injection pipe 8 to rotate accordingly, thereby adjusting the injection direction of the injection pipe 8.

[0036] An adjustment unit 10 is provided above the limiting ring 9. The adjustment unit 10 includes a rectangular cylinder 101, which is fixedly connected to the upper end of the limiting ring 9. When the rectangular cylinder 101 moves, it can drive the limiting ring 9 to move synchronously. A threaded cylinder 102 is fixedly connected to the upper surface of the spray housing 4. A screw 103 is threadedly connected inside the threaded cylinder 102. When the screw 103 rotates, it can move up and down relative to the threaded cylinder 102. A knob 104 is fixedly connected to the upper end of the screw 103. The operator can drive the screw 103 to rotate quickly by turning the knob 104. The outer side of 104 is provided with anti-slip texture to increase the friction between the screw and the worker's hand and reduce slippage. The bottom end of the screw 103 is fixedly connected to a rectangular rod 105. When the screw 103 moves, it can drive the rectangular rod 105 to move synchronously. The upper surface of the spray housing 4 is provided with a through hole. The bottom end of the rectangular rod 105 passes through the through hole. The through hole can avoid obstructing the rotation of the rectangular rod 105. The bottom end of the rectangular rod 105 is inserted into the inside of the rectangular cylinder 101. When the rectangular rod 105 rotates, it can drive the rectangular cylinder 101 to rotate synchronously, thereby allowing the limit ring 9 to be rotated and adjusted.

[0037] When the operator turns the knob 104, it will drive the screw 103 to rotate synchronously. At this time, the screw 103 will move and rotate relative to the threaded cylinder 102 in the up and down direction, which will drive the rectangular rod 105 to move and adjust synchronously in the up and down direction. At this time, the rectangular rod 105 will drive the rectangular cylinder 101 to rotate synchronously to adjust the position of the limiting ring 9. At the same time, the rectangular rod 105 will move up and down inside the rectangular cylinder 101 to avoid obstructing the movement of the limiting ring 9.

[0038] Reference Figures 5-6 A tapered strip 11 is fixedly connected to the right end of the baffle 5. When the cutting fluid flows into the spray housing 4 and flows to the left, it can flow along the inclined surface of the tapered strip 11 into the adjacent spray channel 6, which can reduce the influence of the baffle 5 on the flow of the cutting fluid. A chamfer 12 is provided on the right side of the guide sleeve 7. Similarly, when the cutting fluid flows into the guide sleeve 7, the chamfer 12 can guide the flow of the cutting fluid, so that the cutting fluid can flow quickly into the guide sleeve 7.

[0039] Working principle: The operator can rotate the knob 104 according to the length of the workpiece being processed, which in turn drives the screw 103 to rotate. The screw 103 drives the rectangular rod 105 to move linearly up and down relative to the threaded cylinder 102 and rotate, which in turn drives the rectangular cylinder 101 and the limiting ring 9 to rotate accordingly, causing the spray pipe 8 to rotate and the spray position to be adjusted. Multiple spray pipes 8 are set to provide multi-point spray cooling, which increases the cooling range. At the same time, the angle of the spray pipe 8 can be adjusted to adapt to workpieces of different lengths, improving the adaptability of the device. The structure is simple and the operation is convenient.

[0040] Then, the shaping hose 3 can be moved to the desired spray position, and the infusion pump 2 can be started to draw the cutting fluid from the reservoir 1 into the spray housing 4 through the shaping hose 3, and then into the guide sleeve 7. Finally, it is sprayed out through the spray pipe 8 to reach the cutting position. When the cutting fluid enters the spray housing 4, it can flow quickly into the guide sleeve 7 along the inclined surfaces of the tapered strip 11 and the chamfer 12.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
