[0028] Reference Figure 1 and Figure 2 The embodiment of the present application provides a groove pressing device, which specifically includes a first frame 110. A first driving member and a cooling platform 120 capable of linear motion in a horizontal direction are arranged on the top of the first frame 110. The first driving member is used to drive the cooling platform 120 to perform linear reciprocating motion. A channel for the circulation of a cooling medium is arranged in the cooling platform 120. When in use, cooling water or other cooling liquid is introduced into the channel.

[0029] At least one second frame 130 is disposed on the first frame 110, and the second frame 130 is disposed above the cooling platform 120 and does not affect the movement of the cooling platform 120. In this embodiment, two second frames 130 are disposed on the first frame 110, and each second frame 130 is provided with a pressing groove.

[0030] The groove pressing part includes a second driving member 210, a transmission structure and a groove pressing assembly 300. The transmission structure is slidably arranged on the second frame 130. The groove pressing assembly 300 is installed on one side of the transmission structure facing the cooling platform 120, and the other side is connected to the second driving member 210 fixed to the second frame 130. The second driving member 210 is used to drive the groove pressing assembly 300 to move closer to or away from the cooling platform 120. The groove pressing assembly 300 includes a groove pressing knife 310 and a pre-pressing member 320. A heating rod is arranged in the groove pressing knife 310. Specifically, a plurality of heating holes 311 for placing heating rods are provided in the grooving knife 310, and the pre-pressing piece 320 is covered outside the grooving knife 310. The pre-pressing piece 320 is movably connected to the transmission structure so that the pre-pressing piece 320 can move to fit the grooving knife 310. It should be noted that when the grooving operation is not performed, the pre-pressing piece 320 does not contact the grooving knife 310, and under the action of external force, the pre-pressing piece 320 can move to fit the grooving knife 310. When grooving, the inner side of the pre-pressing piece 320 fits with the grooving knife 310.

[0031] When the grooving device of the present application is in use, after the cooling platform 120 has positioned the product to be grooved, the cooling platform 120 is driven by the first driving member to perform linear motion to move the position of the product to be grooved to directly below the grooving portion. After the grooving knife 310 and the pre-pressing member 320 are installed and calibrated, the transmission structure is driven by the second driving member 210 to perform linear motion to drive the grooving portion to move toward or away from the product, thereby completing the grooving of the product.

[0032] In the embodiment of the present application, the transmission structure plays a guiding role, which is convenient for accurately guiding the grooving part to the position of the product to be grooved; when grooving, as the second driving member 210 continues to move, the grooving part slowly approaches the product, and the first thing to contact the product is the pre-pressing member 320. The pre-pressing member 320 also plays a role in pre-tightening and fixing the product during grooving to avoid displacement or shaking of the position of the product during the grooving process. As the grooving knife 310 continues to approach, the pre-pressing member 320 slowly fits the grooving knife 310. Under the action of the force provided by the second driving member 210, the grooving knife 310 and the pre-pressing member 320 cooperate to achieve V-groove pressing of the product.

[0033] Among them, before grooving, the grooving knife 310 is preheated by a heating rod, and the grooving operation is performed after the grooving knife 310 is heated to the rated temperature. After the grooving is completed, a cooling medium is introduced into the channel of the cooling platform 120, so that the product can be cooled in time after the grooving is completed, which is convenient for shaping and finalizing the groove; when grooving, the grooving knife 310 drives the pre-pressed part 320 to press against the product for 15 to 25 seconds, and then the grooving is completed, and then the grooving knife 310 returns to a certain height. The height to which the grooving knife 310 returns is based on not affecting the contact between the pre-pressed part 320 and the product, so as to achieve rapid separation of the grooving knife 310 and the pre-pressed part 320. Because the pre-pressed part 320 is a movable connection transmission structure, under the action of gravity, the pre-pressed part is still pre-pressed on the product to form a groove, and the pre-pressed part 320 is used to shape the product when it is cooled and finalized, thereby reducing the rebound amount caused by rapid cooling after grooving, thereby greatly improving the forming quality of the V-groove. The present application adopts a first driving member to drive the cooling platform 120 to adjust the position of the product, and cooperates with the setting of the pre-pressing member 320. The structurally optimized grooving device makes the grooving forming size accuracy high, the rebound rate of the forming groove small, and can effectively solve the problem of product deviation or shaking during grooving.

[0034] In some embodiments, Figure 1 and Figure 2 As shown, the first driving member includes a motor 141 and a screw rod 142. The cooling platform 120 is slidably connected to the first frame 110 through a slide rail slider structure so that the cooling platform 120 can perform linear motion. The motor 141 is fixed to the first frame 110 and is connected to the cooling platform 120 through a screw rod 142. Specifically, the screw nut of the screw rod 142 is fixedly connected to the cooling platform 120. The screw rod 142 is rotatably set on the first frame 110 through a screw rod fixing seat and is guided by a guide rail slider structure. The rotation of the motor 141 is converted into a linear reciprocating motion of the cooling platform 120 through the screw rod 142 to achieve precise displacement of the cooling platform 120. Compared with the original manual adjustment of the cooling platform 120, the displacement adjustment of the cooling platform 120 is more precise through the cooperation of the motor 141 and the screw rod 142.

[0035] In some embodiments, the transmission structure includes a mounting seat 260, such as Figure 7 As shown, the mounting seat 260 has a fixing groove 261, and the groove pressing knife 310 is partially inserted into the fixing groove 261 and fastened by a plurality of first fasteners 330. The fixing groove 261 plays a positioning role, which facilitates the rapid assembly of the groove pressing knife 310. At the same time, it is more convenient to replace the groove pressing knife 310 of different sizes by locking through the first fasteners 330.

[0036] Further, such as Figure 3 and Figure 4As shown, there is a gap between the groove pressing knife 310 and the groove wall of the fixed groove 261, and part of the pre-pressing member 320 is located in the gap so that the pre-pressing member 320 has enough space to move. The first fastener 330 is threadedly connected to the mounting seat 260 and enters the fixed groove 261 to resist the groove pressing knife 310. In the embodiment of the present application, the first fastener 330 is preferably a bolt, such as Figure 7 As shown, the mounting seat 260 has a threaded hole 262 adapted to the first fastener 330. The first fastener 330 facilitates the disassembly and assembly of the groove pressing knife 310 through a threaded connection, and facilitates the rapid replacement of groove pressing knives 310 of different models.

[0037] Further, such as Figure 1 and Figure 5 As shown, the pre-pressed part 320 has a contoured groove 325, and the shape of the contoured groove 325 is similar to that of the grooving knife 310. The pre-pressed part 320 is movably connected to the first fastener 330. Different types of grooving knives 310 correspond to different pre-pressed parts 320. When different types of grooving knives 310 are replaced, the pre-pressed part 320 should be replaced together. The first fastener 330 not only realizes the locking of the grooving knife 310, but also satisfies the connection with the pre-pressed part 320, so that the pre-pressed part 320 can move in the vertical direction without separating from the mounting seat 260. The connection is simple and the matching replacement is also convenient.

[0038] Further, such as Figure 6 As shown, both sides of the pre-pressed part 320 are provided with U-shaped grooves 324 for the first fastener 330 to pass through, and the extension direction of the U-shaped grooves 324 is parallel to the movement direction of the groove pressing knife 310, so that the pre-pressed part 320 does not contact the groove pressing knife 310 when the groove pressing operation is not performed, and the pre-pressed part 320 can move to fit the groove pressing knife 310 under the action of external force, and when the groove is pressed, the inner side of the pre-pressed part 320 fits the groove pressing knife 310. Among them, the number and position of the U-shaped grooves 324 correspond to the number and position of the first fastener 330.

[0039] In a preferred embodiment, Figure 5 As shown, the pre-pressed part 320 is a plate part. The pre-pressed part 320 can be made of die steel. The middle of the plate part is concave to make the two sides approach each other, thereby forming a contoured groove 325. The thickness c of the plate part is 1 to 3 mm.

[0040] In some embodiments, when the groove pressing device is not started, the bottom of the pre-pressing member 320 is at a certain distance from the bottom of the groove pressing knife 310. Specifically, Figure 4 As shown, the end of the forming structure of the grooving knife 310 is spaced from the position of the forming structure corresponding to the profiling groove 325 (here, Figure 5 The distance d1 of the lowest position of the groove 321 in the groove is set to 10 to 15 mm.

[0041] It should be noted that the surface of the pre-press 320 that contacts the product is provided with Teflon.

[0042] In some other embodiments, the second driving member 210 is a cylinder, and each second frame 130 is provided with two second driving members 210 to simultaneously drive the transmission structure to move. The transmission structure also includes a connecting plate 220. The cylinder is connected to the connecting plate 220 through a floating joint, and the connecting plate 220 is connected to the mounting seat 260 through a double-headed screw plug 230. Figure 1 As shown, the second frame 130 is in an inverted U shape, and the two ends of the connecting plate 220 are respectively connected to the vertical plates 131 located on both sides of the second frame 130 through the slide rail slider structure, so that the transmission structure can perform linear motion in the vertical direction.

[0043] Specifically, Figure 8 As shown, the cross section of the connecting plate 220 is U-shaped, and the slide rail and slider structure includes a slide rail 252 fixed to the vertical plate 131 and a slider 251 matched with the slide rail 252, and the slider 251 is connected to the connecting plate 220 through an L-shaped connecting block 240. Both ends of the connecting plate 220 are slidably connected to the vertical plate 131 through the slide rail and slider structure, and the slide rail and slider structure plays a guiding role.

[0044] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
