[0040] An embodiment of the present application provides a window cutting device for cutting windows of materials such as stamping products 80. Specifically, referring to FIG. 1 and FIG. 2, the window cutting device of an embodiment includes a lower mold mechanism and an upper mold mechanism, wherein the lower mold mechanism includes a first template 10, a sliding seat 20, a positioning column 50, a first slider 31 and a second slider 41, the sliding seat 20 is fixed to the first template 10, the positioning column 50 is arranged on the sliding seat 20 and is used to fix the product 80, the first slider 31 is slidably connected to the sliding seat 20 and is located on one side of the positioning column 50, the first slider 31 is provided with a cutting male mold 32 for cutting the product 80, the second slider 41 is slidably connected to the sliding seat 20 and is located on the other side of the positioning column 50, and the second slider 41 is provided with a cutting female mold 42 for cooperating with the cutting male mold 32. The upper mold mechanism is arranged opposite to the lower mold mechanism, and the upper mold mechanism can move closer to or away from the lower mold mechanism. The upper mold mechanism includes a second mold plate 70 and a first wedge block 71 and a second wedge block 72 arranged on the second mold plate 70. The first wedge block 71 is arranged opposite to the first slider 31, and the second wedge block 72 is arranged opposite to the second slider 41. When the upper mold mechanism moves toward the lower mold mechanism, the first wedge block 71 can abut against the first slider 31 and drive the first slider 31 to move toward the positioning column 50, and the second wedge block 72 can abut against the second slider 41 and drive the second slider 41 to move toward the positioning column 50.
[0041] When the above-mentioned window cutting device cuts a window on the product 80, the product 80 is first placed on the positioning column 50, and then the second mold is moved close to the first mold, so that the first wedge block 71 abuts against the first slider 31, and the second wedge block 72 abuts against the second slider 41. Then, under the drive of the first wedge block 71 and the second wedge block 72, the first slider 31 and the second slider 41 are moved in opposite directions close to the positioning column 50, and finally the cutting male mold 32 and the cutting female mold 42 respectively hit the two sides of the wall of the product 80, thereby punching out the required window in the product 80. Compared with the traditional method of first punching out the basic shape of the product on the stamping production line, and then transferring the product to the cutting mechanism of the subsequent process to cut the window, the window cutting device of the present application can cut the window on the product 80 by pressing the upper mold mechanism down to the lower mold mechanism, so as to adapt to the working mode of the stamping production line, and the required window can be punched on the product 80 on the stamping production line, without transferring the product 80 to the subsequent process for cutting, thus saving process steps and improving production efficiency. In addition, the window cutting device has a simpler structure, is suitable for feeding by a robot arm, is more convenient to maintain, and has low cost.
[0042] 4 and 5, optionally, in one embodiment, the sliding seat 20 is provided with a T-shaped slide groove 21, and the first slider 31 and the second slider 41 are both limited in the T-shaped slide groove 21 and can slide along the T-shaped slide groove 21. Specifically, the lower end size of the first slider 31 and the second slider 41 is larger than the notch size of the T-shaped slide groove 21, so that the first slider 31 and the second slider 41 can be limited in the T-shaped slide groove 21, and the first slider 31 or the second slider 41 can be prevented from escaping from the sliding seat 20 during operation.
[0043] Referring to Figure 2, optionally, in one embodiment, the first slider 31 is provided with a first inclined surface 313 for cooperating with the first wedge block 71. When the upper mold mechanism moves toward the lower mold mechanism, the first wedge block 71 contacts and cooperates with the first inclined surface 313 to move the first slider 31 toward the positioning column 50, thereby achieving the goal of making the cutting male mold 32 on the first slider 31 impact one side of the wall of the product 80. Similarly, the second slider 41 is provided with a second inclined surface 411 for cooperating with the second wedge block 72. When the upper mold mechanism moves toward the lower mold mechanism, the second wedge block 72 contacts and cooperates with the second inclined surface 411 to move the second slider 41 toward the positioning column 50, thereby achieving the goal of making the cutting female mold 42 on the second slider 41 impact the other side of the wall of the product 80, and then making the cutting male mold 32 cooperate with the cutting female mold 42 to punch out a window on the product 80.
[0044] 2 and 3, one end of the cutting male die 32 protrudes from the first slider 31 toward the second slider 41 to form a cutter head, and a matching hole 421 matching the cutter head is provided on one side of the cutting female die 42 close to the first slider 31. When punching the product 80, the cutter head of the cutting male die 32 breaks through the wall of the product 80 and penetrates into the matching hole 421 of the cutting female die 42, thereby punching out a window on the wall of the product 80.
[0045] 3 and 6, optionally, in one embodiment, the positioning column 50 is provided with an avoidance groove 51 and an avoidance opening 52, the avoidance groove 51 passes through the side of the positioning column 50 close to the first slider 31, at least a portion of the first slider 31 is disposed in the avoidance groove 51, the avoidance opening 52 passes through the side of the positioning column 50 close to the second slider 41, the avoidance opening 52 is disposed opposite to the matching hole 421, and the cutter head can pass through the avoidance opening 52 and penetrate into the matching hole 421. Specifically, in this embodiment, the product 80 is a cylindrical structure, and when cutting the window, the product 80 is sleeved on the positioning column 50. By opening an avoidance groove 51 in the positioning column 50 and setting at least a portion of the first slider 31 in the avoidance groove 51, during cutting, the cutting male mold 32 can impact the inner wall of the product 80 through the avoidance opening 52 and penetrate into the matching hole 421 of the cutting female mold 42, thereby punching out a window on the wall of the product 80 and avoiding interference between the first slider 31 and the positioning column 50.
[0046] Furthermore, the first slider 31 includes a matching portion 312 and a cutting portion 311 which are arranged at intervals. The cutting portion 311 is located in the avoidance groove 51 and connected to the cutting male mold 32, and the matching portion 312 is located outside the avoidance groove 51 and is used to match with the first wedge block 71. By forming a gap between the matching portion 312 and the cutting portion 311, it is ensured that the cutting portion 311 can penetrate into the avoidance groove 51 of the positioning column 50 and the product 80, and the matching portion 312 is prevented from interfering with the product 80. Specifically, the first inclined surface 313 is provided on the matching portion 312 so that the matching portion 312 matches with the first wedge block 71 to achieve driving the first slider 31 to move.
[0047] Optionally, in one embodiment, the lower mold mechanism further includes a first elastic reset member (not shown), one end of the first elastic reset member is connected to the side of the first slider 31 away from the positioning column 50, and the other end is connected to the first template 10, and the first elastic reset member is used to drive the first slider 31 to move away from the positioning column 50 when the upper mold mechanism is away from the lower mold mechanism, so that the first slider 31 returns to the initial position after the window is cut, so as to remove the cut product 80 from the positioning column 50. Preferably, the first elastic reset member can be a tension spring.
[0048] Similarly, the lower mold mechanism further includes a second elastic reset member (not shown), one end of which is connected to the side of the second slider 41 away from the positioning column 50, and the other end is connected to the second template 70. The second elastic reset member is used to drive the second slider 41 to move away from the positioning column 50 when the upper mold mechanism is away from the lower mold mechanism, so that the second slider 41 returns to the initial position after the window is cut, so as to remove the cut product 80 from the positioning column 50. Preferably, the second elastic reset member can also be a tension spring.
[0049] Referring to Fig. 1 and Fig. 2, the window cutting device further comprises a push plate 60, a first elastic member (not shown) and a push rod 73, wherein the push plate 60 is movably arranged on the first template 10, and the push plate 60 has a evacuation position for evading the product 80 and a pushing position for pushing the product 80 away from the positioning column 50. The first elastic member is arranged between the push plate 60 and the first template 10, and the first elastic member is used to maintain the push plate 60 in the pushing position, and the push rod 73 is arranged on the second template 70, and when the upper mold mechanism moves toward the lower mold mechanism, the push rod 73 abuts against the push plate 60 and drives the push plate 60 into the evacuation position.
[0050] Specifically, when it is necessary to cut a window on the product 80, the upper mold mechanism moves toward the lower mold mechanism, so that the push rod 73 abuts against the push plate 60 and drives the push plate 60 to resist the elastic force of the first elastic member and descend to the avoidance position. At this time, the product 80 can be placed on the positioning column 50. As the lower mold mechanism continues to descend, the first wedge block 71 and the second wedge block 72 respectively drive the first slider 31 and the second slider 41 to move toward each other, so that the cutting male mold 32 and the cutting female mold 42 cooperate to cut a window on the product 80. After the window is cut on the product 80, the upper mold mechanism moves away from the lower mold mechanism, so that the push rod 73 is separated from the push plate 60. At this time, the first elastic member pushes up the push plate 60 under the action of the elastic force, so that the push plate 60 returns to the pushing position. At this time, the product 80 on the positioning column 50 is pushed up by the push plate 60, so that it is convenient to take the product 80 out of the positioning column 50.
[0051] Furthermore, the push plate 60 is provided with a first air avoidance opening 61, a second air avoidance opening 62 located on one side of the first air avoidance opening 61, and a third air avoidance opening located on the other side of the first air avoidance opening 61. The positioning column 50 is located in the first air avoidance opening 61, the first slider 31 is arranged in the second air avoidance opening 62, and the second slider 41 is arranged in the third air avoidance opening 63, so as to avoid interference between the push plate 60 and the positioning column 50, the first slider 31 or the second slider 41 during the movement.
[0052] Referring to Figure 1, optionally, in one embodiment, the upper mold mechanism also includes a pressing rod 74, which is arranged on the second mold plate 70 and opposite to the positioning column 50. The pressing rod 74 is used to abut and cooperate with the product 80 when the upper mold mechanism moves toward the lower mold mechanism, thereby pressing the product 80 against the positioning column 50 to prevent the product 80 from detaching from the positioning column 50 during the cutting process.
[0053] Furthermore, the pressing rod 74 is telescopically arranged on the second template 70, and a second elastic member (not shown) is arranged between the pressing rod 74 and the second template 70, so that the second elastic member can ensure that the pressing rod 74 can always be connected to the product 80 during the continuous downward pressing process of the upper mold mechanism, which not only ensures that the pressing rod can press the product 80 tightly against the positioning column 50, but also prevents the pressing rod from damaging the product 80. Thus, the quality of the product 80 is guaranteed.
[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0055] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
