Description

Technical Field

[0001] This application relates to the field of devices for part processing, and particularly to a sawing machine. Background Art

[0002] A sawing machine is a machine tool commonly used in the processing of metal workpieces. Common sawing machines include a workbench, on which a saw blade and a driving device for driving the saw blade to work for cutting parts are installed. It also includes a cutting fluid spraying device. There is a drainage groove on the workbench, and a waste tray is also provided at the bottom of the sawing machine. The drainage end of the drainage groove is located in the waste tray. When using the sawing machine, an operator controls the driving device to work, so that the saw blade cuts the workpiece. At the same time, the cutting fluid spraying device sprays cutting fluid on the workpiece processing position to reduce the temperature at the processing site. The waste chips generated when cutting the workpiece flow into the waste tray at the bottom of the sawing machine along with the cutting fluid through the drainage groove for collection.

[0003] Since the shapes of the waste chips are irregular, some waste chips may be intertwined, and it is difficult for the cutting fluid to wash the waste chips into the waste tray, resulting in the operator having to manually clean the accumulated waste chips, increasing the workload of the operator. Utility Model Content

[0004] In order to reduce the workload of the operator, this application provides a sawing machine.

[0005] This application provides a sawing machine adopting the following technical scheme:

[0006] A sawing machine includes a workbench. The workbench is hollow and is provided with a door. A material hole communicating with the inside of the workbench is opened at the position corresponding to the processing position on the workbench. The positions on both sides of the material hole on the surface of the workbench are gradually inclined downward along the direction close to the material hole, forming a guiding surface.

[0007] A liquid collecting tray is placed inside the workbench, and the liquid collecting tray is located below the material hole.

[0008] Two first motors are installed on the inner wall of the workbench. The two first motors are respectively located on both sides of the material hole. A cam is installed on the output shaft of the first motor, and the longest radius of the cam is greater than the distance between the axis of the cam and the lower surface of the workbench.

[0009] By adopting the above technical solution, when the sawing machine is working, the cutting fluid carries the waste chips and flows to the guiding surface, and then through the inclined guiding surface, it falls into the liquid collecting tray through the material hole for collection. At the same time, the first motor is started, and the first motor drives the cam to rotate. Since the longest radius of the cam is greater than the distance between the axis of the cam and the lower surface of the workbench, every time the cam rotates one week, the cam strikes the top surface of the workbench once. As the first motor works, the cam continuously strikes the workbench, causing the workbench to vibrate. The waste chips that are not washed away by the cutting fluid and stay on the guiding surface move along with the vibration, and finally the waste chips fall into the liquid collecting tray for collection, reducing the possibility that the operator needs to manually clean the waste chips, thereby reducing the workload of the operator.

[0010] Optionally, the inner top surface of the workbench is connected with a filter box located above the liquid collecting tray. The top of the filter box is open, and the open top of the filter box is aligned with the material hole.

[0011] By adopting the above technical solution, the waste chips and the cutting fluid fall into the filter box through the material hole. The filter box screens the cutting fluid and the waste chips. The waste chips remain in the filter box, and the cutting fluid falls into the liquid collecting tray for collection. The collected cutting fluid can be reused after being processed, saving costs.

[0012] Optionally, an extrusion assembly is provided in the filter box.

[0013] By adopting the above technical solution, the extrusion assembly can extrude the waste chips in the filter box to make the waste chips into a mass, so that more waste chips can be accommodated in the filter box, extending the time for cleaning the filter box, and can also extrude the cutting fluid attached to the waste chips, enabling better recovery of the cutting fluid.

[0014] Optionally, the extrusion assembly includes two pressing plates arranged in the filter box, and the extrusion assembly further includes a power member for driving the two pressing plates to move along the length direction of the workbench.

[0015] By adopting the above technical solution, in the initial state, the power member positions the two pressing plates at the two side edges of the filter box respectively, and the waste chips fall between the two pressing plates. When it is necessary to extrude the waste chips, the operator starts the power member, and the power member works to move the two pressing plates towards each other in the downward direction, thereby extruding the waste chips. After the extrusion is completed, the operator then controls the power member to move the two pressing plates away from each other to reset the two pressing plates.

[0016] Optionally, the power member includes a lead screw rotatably connected to the workbench. The length direction of the lead screw is consistent with the length direction of the workbench. The lead screw is a bidirectional lead screw. Both pressing plates are threadedly connected to the lead screw, and the thread directions of the two pressing plates are opposite. A second motor for driving the lead screw to rotate is further installed on the workbench. A slider is connected to the pressing plate, and the slider is slidably connected to the filter box.

[0017] By adopting the above technical solution, when it is necessary to move the two pressing plates in the direction of approaching each other, the second motor is started, and the second motor drives the lead screw to rotate. At the same time, the slider cooperates with the filter box to guide the pressing plate, so that the pressing plate moves along the length direction of the workbench; when it is necessary to move the two pressing plates in the direction of moving away from each other, the second motor is controlled to work, so that the output shaft of the second motor rotates in the reverse direction, so that the two pressing plates move in the direction of moving away from each other.

[0018] Optionally, a circle of baffles is connected to the top of the filter box, the upper surface of the baffle is connected to the lower surface of the workbench, the lower end of the filter box is also open, and a bottom plate for blocking the open lower end of the filter box is hinged to the lower end of the filter box, and the bottom plate is fixed to the filter box through a buckle.

[0019] By adopting the above technical solution, the baffle guides the cutting fluid and the waste chips, so that the waste chips and the cutting fluid can enter the filter box better.

[0020] Optionally, each baffle of the circle is inclined upward in the direction of moving away from each other.

[0021] By adopting the above technical solution, the cutting fluid and the waste chips can slide down to the filter box better along the inclined baffle.

[0022] Optionally, sliding grooves corresponding to the sliders one by one are formed on the inner wall of the filter box, the length direction of the sliding grooves is arranged along the length direction of the workbench, and each slider is slidably inserted into the corresponding sliding groove.

[0023] By adopting the above technical solution, the slider and the sliding groove cooperate to guide the pressing plate, so that the pressing plate can move along the length direction of the workbench.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. By providing the workbench, the diversion surface, the material hole, the liquid collecting tray, the first motor and the cam, the workload of the operator is reduced;

[0026] 2. By providing the filter box, the waste chips and the cutting fluid can be screened, and the cutting fluid can be recycled, saving costs;

[0027] 3. By providing the pressing plate and the power component, the waste chips can be extruded, the time for cleaning the filter box can be extended, and the cutting fluid can be recycled better. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0033] The following will further elaborate on the present application in conjunction with the Figures 1-4 accompanying drawings.

[0034] An embodiment of the present application discloses a sawing machine. Referring to Figure 1 and Figure 2 , it includes a workbench 1. The workbench 1 is hollow and equipped with a door. At the position corresponding to the processing location on the workbench 1, a material hole 11 communicating with the inside of the workbench 1 is provided. The surfaces of the workbench 1 on both sides of the material hole 11 gradually slope downward in the direction approaching the material hole 11, forming a diversion surface 12. A liquid collecting tray 2 is placed inside the workbench 1. The liquid collecting tray 2 is located below the material hole 11 and is used to collect cutting fluid and waste chips.

[0035] Referring to Figure 2 , the inner top surface of the workbench 1 is connected with a filter box 3 located above the liquid collecting tray 2. The top of the filter box 3 is open, and the top opening of the filter box 3 is aligned with the material hole 11; the lower end of the filter box 3 is also open, and a bottom plate 31 for blocking the lower opening of the filter box 3 is hinged to the lower end of the filter box 3. The bottom plate 31 is fixed to the filter box 3 through a lock, and filter holes are also provided on the bottom plate 31. A circle of baffles 32 is connected to the top of the filter box 3. The upper surface of the baffles 32 is connected to the lower surface of the workbench 1. In order to better guide the cutting fluid and waste chips into the filter box 3, the baffles 32 slope away from each other from bottom to top.

[0036] Referring to Figure 2 and Figure 3 , two first motors 4 are installed on the inner wall of the workbench 1. The two first motors 4 are respectively located on both sides of the material hole 11. A cam 5 is installed on the output shaft of the first motor 4. The longest radius of the cam 5 is greater than the distance between the axis of the cam 5 and the lower surface of the workbench 1.

[0037] When the first motor 4 starts, the cam 5 rotates and strikes the workbench 1, causing the workbench 1 to vibrate, thereby shaking off the waste chips staying on the diversion surface 12 into the collecting workbench 1; the cutting fluid and waste chips fall into the filter box 3 through the material hole 11, and the filter box 3 screens the cutting fluid and waste chips. The waste chips remain in the filter box 3, and the cutting fluid flows into the liquid collecting tray 2 through the pores of the filter box 3 for collection.

[0038] Referring to Figure 2 With Figure 3 , in order to further improve the accommodation capacity of the filter box 3, an extrusion assembly 6 is also provided in the filter box 3. The extrusion assembly 6 includes two pressing plates 61 arranged in the filter box 3, and a power member 62 for driving the two pressing plates 61 to move along the length direction of the workbench 1; the power member 62 includes a lead screw 621 rotatably connected in the workbench 1. The lead screw 621 is a bidirectional lead screw 621, and both pressing plates 61 are threadedly connected to the lead screw 621, and the thread directions of the two pressing plates 61 are opposite.

[0039] Referring to Figure 3 With Figure 4 , sliding blocks 611 are fixedly connected to the opposite two side walls of the pressing plate 61, and sliding grooves 33 corresponding to the sliding blocks 611 one by one are also formed on the inner wall of the filter box 3. The length direction of the sliding grooves 33 is arranged along the length direction of the workbench 1, and each sliding block 611 is slidably inserted into the corresponding sliding groove 33; a second motor 622 for driving the lead screw 621 to rotate is also installed on the workbench 1.

[0040] When it is necessary to extrude the waste chips, the second motor 622 is started to drive the lead screw 621 to rotate, so that the two pressing plates 61 approach each other, thereby extruding the waste chips, enabling the cutting fluid attached to the waste chips to better fall into the liquid collecting tray 2, so that the cutting fluid can be better collected. The collected cutting fluid can be reused after being processed, which can save production costs. The waste chips are agglomerated after extrusion, reducing the volume occupied in the filter box 3, so that the filter box 3 can accommodate more waste chips and extend the time for the operator to clean the filter box 3.

[0041] After the waste chips are extruded, the operator controls the second motor 622 to work, so that the lead screw 621 rotates in the reverse direction, so that the two pressing plates 61 move away from each other until the pressing plates 61 are reset. When it is necessary to clean the waste chips in the filter box 3, the operator opens the lock and opens the bottom plate 31, so as to conveniently clean the waste chips out of the filter box 3.

[0042] The implementation principle of a sawing machine in an embodiment of this application is as follows: When an operator cuts a workpiece, the first motor 4 is started. The first motor 4 operates and drives the cam 5 to rotate. The cam 5 knocks on the inner top surface of the workbench 1, and the waste chips fall off and enter the filter box 3, and the cutting fluid also falls into the liquid collecting box. The second motor 622 is started to make the lead screw 621 rotate forward, and the two pressing plates 61 move towards each other and squeeze the waste chips. After the squeezing is completed, the second motor 622 is controlled to operate, so that the lead screw 621 rotates reversely and drives the two pressing plates 61 to move away from each other and reset. When it is necessary to take out the waste chips, the lock is opened, the bottom plate 31 is rotated and the waste chips are taken out, and finally the bottom plate 31 is rotated and the lock is used to fix the bottom plate 31 to the filter box 3.

[0043] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
