[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the solution will be further described in detail below in conjunction with specific embodiments.

[0036] like Figures 1 to 9 As shown, an embodiment of the present invention provides a sheet oiling mechanism 91, which includes a fixed sleeve 21, a movable sleeve 31, and an oil spray assembly for connecting to an oil supply device. The upper end of the fixed sleeve 21 is provided with a connecting mechanism for connecting to the front side of a workbench 81 on a machine tool. The rear side of the workbench on the machine tool is provided with an upper die seat. The fixed sleeve 21 is perpendicular to the workbench on the machine tool; the movable sleeve 31 is slidably arranged in the fixed sleeve 21, and a long strip hole 32 for slidingly cooperating with a fixed pin 33 is vertically provided on the movable sleeve. , the fixed pin is perpendicular to the movable sleeve, and a first limiting hole 22 is provided on one side of the fixed sleeve for one end of the fixed pin to pass through, and a second limiting hole is provided on the other side of the fixed sleeve for the other end of the fixed pin to pass through, and the first limiting hole and the second limiting hole are arranged opposite to each other; the lower end of the movable sleeve is connected to the oil injection assembly, and the oil injection assembly includes an oil nozzle 52 for spraying oil to the sheet material 71 set on the lower die base 85 on the lower worktable 84 of the machine tool, and a limiting member for contacting the lower worktable of the machine tool.

[0037] The sheet metal oiling mechanism provided in the embodiment of the present invention is fixed on the workbench of the machine tool through a connecting mechanism, and then the sheet metal is placed directly below the connecting mechanism, that is, directly below the sheet metal oiling mechanism, and the oil nozzle is placed close to the sheet metal, and the movable sleeve is connected to the fixed sleeve through a fixing pin. Figure 1 As shown, the oil supply device then supplies oil to the oil injection assembly, and the oil nozzle sprays the oil on the sheet material to achieve oiling of the sheet material. After the oiling is completed, the sheet material returns to the position directly below the upper die seat, that is, returns to the processing area of ​​the lower die seat; in the process of closing the mold, the fixed sleeve will move downward with the upper workbench of the machine tool and gradually approach the lower workbench of the machine tool. When the limiter contacts the lower workbench of the machine tool, when the workbench of the machine tool continues to descend, the fixed sleeve slides downward along the movable sleeve, and at the same time, the fixed pin slides downward along the long strip hole. Therefore, the sheet material oiling mechanism will not affect the normal operation of the mold until the mold is completely closed and the processing of the sheet material is completed. It can be seen that the present invention can realize automatic oiling of the sheet material without manual oiling, thereby effectively improving the oiling efficiency and reducing the labor intensity of the operator.

[0038] Furthermore, the connecting mechanism includes a fixed plate 11 and two T-blocks 12. The two T-blocks 12 are relatively arranged on the left and right sides of the top surface of the fixed plate. The upper end of the fixed sleeve is connected to the fixed plate. The front side of the workbench on the machine tool is provided with at least two T-slots 82 for slidingly fitting with the T-blocks. With this solution, during installation, it is only necessary to install the T-block into the T-slot, so that the installation between the sheet oiling mechanism and the workbench on the machine tool is more convenient; at the same time, since the T-block slides with the T-slot, the T-block can move forward and backward in the T-slot but cannot move left and right. When it is necessary to adjust the front and rear position of the sheet oiling mechanism in the mold, it is only necessary to slide the T-block forward and backward in the T-slot to the required position. It can be understood that the T-slot extends in the front and rear direction of the workbench on the machine tool; as Figure 6 and Figure 7 As shown, the connecting mechanism, that is, the sheet oiling mechanism, is located in front of the upper die base 83.

[0039] Specifically, there are multiple T-slots 82, and each T-slot is evenly distributed in the extension direction of the worktable on the machine tool, so that the installation position of the sheet oiling mechanism in the left and right directions of the worktable on the machine tool can be easily adjusted by simply matching the T-block with different T-slots.

[0040] Preferably, the number of the first limiting holes 22 and the second limiting holes is at least two, and each of the first limiting holes and the second limiting holes is arranged one by one opposite to each other. With this solution, according to the opening position of the mold, that is, the vertical distance between the upper mold base and the lower mold base, appropriate first limiting holes and second limiting holes are selected to cooperate with the fixing pin to adjust the vertical length of the movable sleeve and the fixed sleeve during installation to ensure that the distance between the nozzle and the sheet material is appropriate, such as Figure 6 As shown, the sheet metal can achieve a better oiling effect, and the sheet metal oiling mechanism can be used when the mold is in different opening positions. It can be understood that the first limiting holes 22 and the second limiting holes are distributed vertically on the fixed sleeve; during installation, the fixing pin is passed through the first limiting hole, the elongated hole, and the second limiting hole, thus achieving a connection between the movable sleeve and the fixed sleeve, preventing the movable sleeve from falling out of the fixed sleeve.

[0041] Furthermore, the fuel injection assembly includes a horizontally arranged oil reservoir 41 and a fixed base 51. An oil inlet pipe 42 for connecting to the fuel supply device is provided on one side of the oil reservoir. Multiple fixed bases 51 are provided, each with one end connected to the base plate 44 of the oil reservoir. Each fixed base 51 is provided with a fuel nozzle 52. The inner cavity of the oil reservoir communicates with each fuel nozzle 52 via oil passages provided within the base plate and each fixed base. With this solution, the fuel supply device is connected to the fuel nozzle 52 via the oil inlet pipe, the inner cavity of the oil reservoir, and the oil passages in the base plate and each fixed base, thereby supplying fuel to the fuel nozzle.

[0042] It is understood that the oil inlet pipe is connected to the inner cavity of the oil storage box. The amount of oil applied can be controlled by a controller. Specifically, an electronic switch valve and an oil quantity sensor, each electrically connected to the controller, are provided on the connecting pipeline between the oil supply device and the oil inlet pipe. When the oil quantity signal sent by the oil quantity sensor indicates that the oil injection quantity of the oil injection assembly has reached a value set in the controller, the controller controls the electronic switch valve to close and stop supplying oil to the oil injection assembly, thereby controlling the amount of oil applied. When the sheet metal needs to be oiled, the controller controls the electronic switch valve to open, and the oil supply device begins to supply oil to the oil nozzle, causing the oil nozzle to spray oil onto the sheet metal, thereby oiling the sheet metal.

[0043] Specifically, the oil storage box 41 is a rectangular box, the lower end of the movable sleeve is connected to the top plate 46 of the oil storage box, and the oil inlet pipe is arranged on the front side plate 47 of the oil storage box; the rear side of the top plate is rotatably connected to the rear side plate 48 of the oil storage box, and a fixing part 43 is provided on at least one of the left plate 45 and the right plate of the oil storage box, and the fixing part 43 is used to keep the top plate 46 covering the upper port of the oil storage box 41. With this solution, it is only necessary to remove the fixing part and then rotate the top plate to open the upper port of the oil storage box, thereby facilitating the cleaning of the inner cavity of the oil storage box. It can be understood that when applying oil, the positional relationship between the fixed sleeve and the oil storage box is as follows Figure 1 As shown; when the mold is fully closed, the positional relationship between the fixed sleeve and the oil storage box is as follows; Figure 2 shown.

[0044] Preferably, there are four fixing seats 51, and the four fixing seats 51 are connected to the bottom surface of the four corners of the bottom plate 44 respectively. Each fixing seat is provided with two oil nozzles, so that the oil sprayed by each oil nozzle can better cover the entire sheet material, thereby enabling the sheet material to obtain a better oiling effect. It is understandable that the installation position and number of the oil nozzles can be set on the fixing seat according to the size of the sheet material so that the sheet material can receive a better oiling effect; when the oil injection assembly is descending, it contacts the lower workbench of the machine tool after passing through the avoidance opening of the lower die seat, such as Figure 8 and Figure 9 As shown, when the mold is completely closed, the sheet oiling mechanism is located in the avoidance port; when oiling, the sheet is placed at the upper end of the avoidance port, as shown in FIG. Figure 6 and Figure 7 As shown; after the oiling is completed, the sheet metal returns to the rear of the avoidance.

[0045] Specifically, there are two limiting members, which are respectively connected to the left side plate 45 and the right side plate of the oil storage box, so that the oil storage box can be better limited, so that the fuel injector and the workbench under the machine tool maintain a certain distance in the vertical direction, avoiding collision between the fuel injector and the workbench under the machine tool.

[0046] Furthermore, the limiting member includes a horizontally arranged mounting seat 61 and a vertically arranged connecting rod 63. One end of the mounting seat 61 is vertically connected to the left side plate, the upper end of the connecting rod is connected to the lower side surface of the other end of the mounting seat, and the lower end of the connecting rod 63 is used to contact the lower workbench of the machine tool, thereby realizing the connection between the limiting member and the left side plate of the oil storage box, and at the same time making the structure of the limiting member relatively simple.

[0047] Specifically, the position limiting member also includes a buffer block 62, the upper end of which is connected to the lower end of the connecting rod 63. This allows the buffer block to contact the lower worktable of the machine tool, providing a better buffering effect and protecting the connecting rod from significant impact. Preferably, the T-block is welded to the fixed plate, which is a rectangular plate. When the mold is fully closed, the buffer block just contacts the lower worktable of the machine tool. The fixed sleeve is welded or threaded to the fixed plate. The movable sleeve is welded to the top plate of the oil reservoir box. The mounting seat is welded to the oil reservoir box. The fixing seat is welded to the bottom plate of the oil reservoir box. The left, front, right, and rear side plates of the oil reservoir box are welded into a rectangular structure, which is then welded to the bottom plate of the oil reservoir box.

[0048] The present invention avoids the problems of wasting oil, namely drawing oil, uneven oiling, and untimely oiling when the roller brush is manually oiled, can effectively improve the oiling efficiency, and also reduces the possibility of quality risks of the sheet material.

It should be pointed out that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Moreover, after reading the contents of the present invention, relevant technical personnel in this field can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
