[0014] As a further improvement of the present invention, the second stamping groove is provided with a clearance end, and the second stamping groove forms a step surface at the connection with the first stamping groove through the clearance end.

[0015] As a further improvement of the present invention, the cutting mechanism includes a connecting plate and a cutting head, the connecting plate is embedded in the second stamping groove and connected to the second stamping plate, and the cutting head is connected to the connecting plate.

[0016] As a further improvement of the present invention, the feeding mechanism includes a feeding plate and a feeding roller, the feeding plate is connected to the punch, the feeding plate is provided with a slide groove, the feeding roller is movably arranged in the slide groove, and the feeding roller is used to convey the profile.

[0017] As a further improvement of the present invention, the lower mold is also provided with a blanking assembly, and the blanking assembly includes a blanking plate, and the blanking plate is connected to the lower mold.

[0022] 1. By adjusting the height of the mold, after each stamping work, the part of the profile that has been stamped will not be completely cut off from the profile to be processed, but a connection point will remain. This can ensure that after the profile is stamped, the feeding mechanism can still feed continuously without adding additional auxiliary devices to achieve the purpose of continuous feeding, which not only saves production costs and subsequent equipment maintenance costs, but also reduces the space occupied by the entire device.

[0024] 3. When stamping profiles of different shapes, it is only necessary to replace the concave die and the punch accordingly, so that the groove is replaced with a U-shaped groove or an L-shaped groove, etc., and at the same time, it is also ensured that the stamping end of the punch is consistent with the shape of the groove, so that profiles of different shapes can be stamped out, which not only improves the convenience of changing the stamping method, but also ensures the diversity and adaptability of the mold when used.

[0025] 4. Adjust the positions of the two feed rollers so that the profile fed into the punch end can be adjusted in length and short sides according to actual needs, thereby controlling the length of the long side and short side of the L-shaped profile after stamping, further improving the flexibility and adaptability of the mold during stamping.

[0026] 5. When the stamped profile is transported to the cutting station, this part of the profile is placed on the transition rod and passes through the two unloading rollers. When the cutting is completed, this part of the profile will fall forward under the action of gravity, thereby achieving the purpose of automatic unloading and avoiding the cut profile from falling directly into the unloading plate. If the cut profile falls directly into the unloading plate, there will be a problem of not being able to unload automatically smoothly due to excessive friction between the profile and the unloading plate, resulting in the need for manual unloading, which not only increases labor expenses but also reduces work efficiency.

DETAILED DESCRIPTION

[0032] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical method of the present invention, but the present invention is not limited to these embodiments.

[0033] like Figure 1-4 As shown, the present invention provides a mold capable of continuously punching and cutting profiles, which includes an upper mold 100 and a lower mold 200. The upper mold 100 completes the mold opening and closing actions with the lower mold 200 by moving up and down, and also includes:

[0034] The feeding mechanism 300 is connected to the lower mold 200 and is used to convey the profile. In the present embodiment, the feeding mechanism 300 can feed continuously, each feeding distance is one station, and has a certain feeding interval. Specifically, the feeding interval keeps a synchronous rhythm with the time of opening and closing the upper mold 100 and the lower mold 200. That is to say, only when the mold is opened, the feeding mechanism 300 will feed the profile to be processed forward one station. Therefore, each time the mold is closed, the profile to be processed has arrived at the designated position waiting for processing, thereby ensuring the smooth completion of the processing and the continuity of the feeding.

[0035] The stamping mechanism includes a die 110 and a punch 210. The die 110 is connected to the upper die 100 and is provided with a groove 120. The punch 210 is connected to the lower die 200 and has a stamping end arranged vertically upward. The die 110 and the punch 210 are arranged correspondingly up and down, wherein the feeding end of the punch 210 is close to the feeding mechanism 300, and the feeding distance of a workstation refers to the feeding distance each time being consistent with the length of the punch 210, that is, before the mold is closed, the profile to be processed is placed on the entire punch 210, and when the upper mold 100 moves downward for mold closing, the punch 210 extends into the groove 120 and stamps the profile into shape.

[0036] In addition, in this embodiment, by adjusting the height of the mold, after each stamping work, the part of the profile that has been stamped is not completely cut off from the profile to be processed, but a connection point remains. This can ensure that after the stamping of the profile is completed, the feeding mechanism can still feed continuously without adding additional auxiliary devices to achieve the purpose of continuous feeding.

[0037] The cutting mechanism 400 is connected to the upper die 100. The cutting mechanism 400 and the stamping mechanism are arranged in a front-to-back correspondence. The cutting mechanism 400 is used to cut the profile formed by the previous stamping. Specifically, after a stamping is completed, the upper die 100 moves upward to open the die. At this time, the feeding mechanism 300 conveys the profile forward one station again. The cutting mechanism 400 can cut the profile that has been stamped. The shearing point is the connection point between the stamped profile and the profile to be processed. At the same time, the profile to be processed will be fed to the punch 210, so that the feeding, stamping and shearing can be carried out continuously, which not only saves the production cost and the maintenance cost of the subsequent equipment, but also reduces the occupied space of the entire device.

[0038] In addition, compared with the use of rolling equipment for continuous feeding, stamping and cutting, the mold plus the feeding mechanism in this embodiment has a total length of only 8 meters, while the rolling equipment plus the feeding mechanism requires 24 meters, which is greatly shortened in length, thereby greatly reducing the footprint of the device and making it more practical.

[0039] Preferably, the die 110 includes a first stamping plate 111 and a second stamping plate 112, the first stamping plate 111 is connected to the second stamping plate 112, the first stamping plate 111 and the second stamping plate 112 are both connected to the upper die 100, and the first stamping plate 111 is close to the feeding mechanism 300, that is, the first stamping plate 111 is close to the feeding end of the punch 210.

[0040] Further preferably, the groove 120 includes a first stamping groove 121 and a second stamping groove 122, the first stamping groove 121 is arranged on the first stamping plate 111, and the second stamping groove 122 is arranged on the second stamping plate 112, and the first stamping groove 121 is connected to the second stamping groove 122. In this embodiment, due to different usage scenarios, the profile needs to be punched into different shapes such as L-shape and U-shape. At this time, it is only necessary to replace the die 110 and the punch 210 accordingly, so that the first stamping groove 121 and the second stamping groove 122 are correspondingly replaced with U-shaped grooves or L-shaped grooves, and the shapes of the first stamping groove 121 and the second stamping groove 122 are consistent. At the same time, it also ensures that the stamping end of the punch 210 is consistent with the shape of the first stamping groove 121 and the second stamping groove 122, so that profiles of different shapes can be stamped out, which not only improves the convenience of changing the stamping method, but also ensures the diversity and adaptability of the mold when used.

[0041] Preferably, the second stamping groove 122 is provided with an air avoidance end 1221, and the second stamping groove 122 forms a step surface at the connection with the first stamping groove 121 through the air avoidance end 1221. In the actual working process, the first stamping plate 111 is not provided with the air avoidance end 1221 in order to more effectively cut the profile, but at the same time it also ensures that the profile will not be completely cut off. The second stamping groove 122 reduces the impact force between the second stamping plate 112 and the profile and the punch 210 during the stamping process by adding the air avoidance end 1221, thereby reducing energy consumption and increasing the service life of the second stamping plate 112 and the punch 210.

[0042] Preferably, the cutting mechanism 400 includes a connecting plate 410 and a cutting head 420. The connecting plate 410 is embedded in the second stamping groove 122 and connected to the second stamping plate 112, and the cutting head 420 is embedded in the connecting plate 410. Therefore, the position of the cutting head 420 can be adjusted by moving the connecting plate 410 along the second stamping groove 122, so that the cutting surface of the cutting head 420 and the blanking end of the punch 210 are in the same vertical direction. That is to say, when cutting the profile, the connection point between the stamped profile and the profile to be processed just protrudes slightly outward from the blanking end of the punch 210, and the cutting position of the profile by the cutting head 420 is located at the connection point. When cutting, the left and right force points at the connection point are close to each other, which is more convenient for cutting.

[0043] Preferably, the feeding mechanism 300 includes a feeding plate 310 and a feeding roller 320, and the feeding plate 310 is connected to the punch 210. Specifically, a fixed plate 220 is provided between the punch 210 and the lower die 200 to raise the height, so that the punch 210 is closer to the upper die 100, reducing the stroke of the upper die 100 when moving up and down to open and close the die, thereby reducing energy consumption. A baffle 230 is provided between the punch 210, the fixed plate 220 and the feeding plate 310 to play a positioning and limiting role. The baffle 230 is set to be rectangular and its height is the same as the height of the stamping end of the punch 210. The setting of the baffle 230 can make the process of feeding the profile from the feed plate 310 to the punch 210 more stable, thereby improving the stability during feeding.

[0044] Further, in Figure 2 In the figure, the feeding mechanism 300 is not completely drawn, but the structure required for feeding has been shown. Specifically, two slide grooves 311 are provided on the feeding plate 310, and the two slide grooves 311 are located on the same axis, and two feeding rollers 320 are movably arranged in the two slide grooves 311, respectively, and a distance is left between the two feeding rollers 320 for conveying the profile. It is precisely because the positions of the two feeding rollers 320 can be adjusted that the profile fed into the stamping end of the punch 210 can be adjusted in length and short sides according to actual needs. For example, when stamping an L-shaped profile, the length of the profile on both sides of the stamping end can be adjusted at any time, thereby controlling the long side length and short side length of the L-shaped profile after stamping, further improving the flexibility and adaptability of the mold during stamping.

[0045] Preferably, the lower die 200 is also provided with a blanking assembly 500, which includes a blanking plate 510. The blanking plate 510 is connected to the lower die 200 and is close to the punch 210. The blanking plate 510 is tilted to facilitate blanking of the cut profile.

[0046] Further preferably, the unloading assembly 500 also includes a transition rod 520 and at least one pair of unloading rollers 530. The transition rod 520 is connected to the lower die 200 and is located between the punch 210 and the unloading roller 530. The unloading roller 530 is connected to the second stamping plate 112. Specifically, the transition rod 520 is located in the vertical space where the unloading plate 510 is located. When the stamped profile is transported to the cutting station, this part of the profile is mounted on the transition rod 520 and passes between the two unloading rollers 530. When the cutting is completed, this part of the profile will fall forward under the action of gravity, thereby achieving the purpose of automatic unloading.

[0047] At the same time, it is precisely because of the provision of the transition rod 520 and the unloading roller 530 that the cut profile is prevented from falling directly into the unloading plate 510. If the cut profile falls directly into the unloading plate 510, there will be a problem that the profile cannot be unloaded automatically smoothly due to excessive friction between the profile and the unloading plate 510, resulting in the need for manual assistance in unloading, which not only increases labor expenses but also reduces work efficiency.

[0048] Preferably, the lower mold 200 is also provided with at least one pair of elastic reset columns 240. The upper mold 100 compresses the elastic reset columns 240 downward when the mold is closed, and the elastic reset columns 240 push the upper mold 100 upward when the mold is opened, thereby reducing energy consumption. The elastic reset columns 240 are provided with guide rollers 250. The guide rollers are located in the vertical space where the stamping mechanism is located. The profile can pass between the two guide rollers 250, thereby guiding the profile to be fed into the punch 210 in a straight line, thereby ensuring the accuracy of the stamping work.

[0049] In addition, the upper mold 100 is also provided with a guide sleeve 130, and the lower mold 200 is also provided with a guide column 260. When the upper and lower molds 200 are closed, the guide column 260 is inserted into the guide sleeve 130 to guide the upper mold 100 and the lower mold 200 to align in the correct position to ensure the smooth progress of stamping and cutting.
