[0028] In the description of the present application, unless otherwise clearly defined, words such as "arrangement", "installation", "connection", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present application in combination with the specific content of the technical solution.
[0029] Currently, the production process of the above product 500 is as follows: the above product 500 is produced with a fixed length, the above product 500 with a fixed length is cut into above segments 510, and the above segments 510 are bent into left or right parts of the above product. Among them, the fixed-length cutting and bending of the above product 500 are carried out separately, and positioning needs to be carried out again each time before bending. The production requires a lot of equipment and processes, and the efficiency cannot be effectively improved.
[0030] For this reason, refer to Figures 1 to 5, an embodiment of the present application provides a processing device for cutting and bending the upper strip of a door frame, which can perform fixed-length cutting of the upper strip on the same device, and can perform bending and forming of the upper strip segment 510 without repositioning after cutting. Specifically, the processing device for cutting and bending the upper strip of the door frame in the present application includes two groups of bending dies 100, a punching die 210, a pressing die 220, and a bending mechanism. Among them, the two groups of bending dies 100 are arranged at intervals, and a profiling part 120 for shaping the upper strip segment 510 is arranged on each group of bending dies 100; the punching die 210 is arranged between the two groups of bending dies 100, and the pressing die 220 is arranged opposite to the punching die 210. The pressing die 220 is used to fix the upper strip product 500 to the positioning part of the punching die 210, so that the cutter of the punching die 210 can cut the upper strip product 500 into two upper strip segments 510; a bending mechanism is arranged at one end of each bending die 100 away from the punching die 210. After the upper strip product 500 is cut into two upper strip segments 510, the upper strip segment 510 is pulled onto the profiling part 120 by the bending mechanism for stretching and shaping to form the left or right part of the upper strip. Specifically, the bending mechanism is mainly an oil pressure bending power head, and the oil pressure bending power head includes an oil pressure bending structure and a clamping part 600. The clamping part 600 is mainly used to clamp the upper strip segment 510, and the oil pressure bending structure drives the clamping part 600 to move, so that the clamping part can drive the upper strip segment 510 to bend.
[0031] During use, the loading robot transfers the upper strip product 500 to the processing device of the present application. When the upper strip product 500 is positioned on the punching die 210, the upper strip product 500 is positioned and pre-tightened by the pressing die 220. At the same time, the cut upper strip segment 510 is also clamped and positioned by the pressing die 220. After the upper strip product 500 is punched into the upper strip segment 510 by the cutter, the bending mechanism is started, and the upper strip segment 510 is brought onto the profiling part 120 by the bending mechanism for bending and shaping, so as to form the left and right parts of the upper strip at one time. The entire processing device can perform fixed-length cutting of the upper strip product 500 to form the left and right parts of the upper strip, and at the same time, the bending and forming of the left and right parts of the upper strip can be completed in one action, so that the cutting and bending of the upper strip can be carried out continuously without repeated positioning, greatly improving the production efficiency.
[0032] It should be noted that the cutter is arranged at the middle position of the positioning part. When the pressing die 220 fixes the upper strip product 500 to the positioning part, the position of the pressing die 220 opposite to the cutter is clear. When the cutter punches the upper strip product 500 into the upper strip segment 510, it can still be pre-tightened by the pressing die 220, so that subsequent bending and forming can be carried out.
[0033] Such as Figures 2 to 4As shown, the bending die 100 further includes a mounting base 110. The mounting base 110 includes two sets of locking structures arranged oppositely. The two sets of locking structures act together to fix the profiling part 120 to the mounting base 110. Specifically, the locking structure includes two locking members 111 arranged at intervals. The two locking members 111 are arranged in parallel. The locking member 111 is threadedly connected to the mounting base 110. In the embodiment of the present application, the locking member 111 is a bolt. The locking members 111 of one set of locking structures can approach the locking members 111 of the other set of locking structures. The locking and fixing of the profiling part 120 is completed by adjusting the approaching or separating of the locking members 111 towards each other. Moreover, the design of the locking structure is ingenious and convenient to adjust, and the positions of the two profiling parts 120 can be adjusted according to the conditions of different upper strip products 500.
[0034] In the embodiment of the present application, the number of mounting bases 110 on each bending die 100 can be adaptively adjusted according to the length of the upper strip section 510. Generally, two mounting bases 110 are provided, and each mounting base 110 is provided with two sets of locking structures arranged oppositely, so as to effectively lock and position the profiling part 120.
[0035] Further, the processing device for cutting and bending the upper strip of the door frame further includes a mounting platform. The bending die 100 is fixed to the mounting platform. The punching die 210 is slidably arranged on the mounting platform. The sliding movement of the punching die 210 is executed by a cylinder. The pressing die 220 slides following the punching die 210. Specifically, the punching die 210 is slidably arranged on the mounting platform through a guide rail and slider structure. After the cylinder is fixed to the mounting platform, the cylinder rod of the cylinder is connected to the punching die 210 through a floating joint, so that the punching die 210 can be translated to a relatively open position to receive the upper strip product 500. When the punching die 210 receives the product, the pressing die 220 that moves following presses the upper strip product 500 against the positioning part, and then returns to the original position, so that the subsequent clamping part 600 can clamp the end of the punched upper strip section 510 for bending operation.
[0036] In some embodiments, a pre-positioning assembly 400 is further provided on the mounting platform. The pre-positioning assembly 400 is close to one end of the profiling part 120 away from the punching die 210. The pre-positioning assembly 400 includes a pre-positioning member and a first cylinder. Under the action of the first cylinder, the pre-positioning member can lift one end of the upper strip product 500 away from the punching die 210 to the movement path of the clamping part 600. Among them, the pre-positioning member has a lifting groove adapted to the upper strip section 510. The length of some upper strip sections 510 is too long, and the free end of the upper strip section 510 is prone to bend downward under the action of gravity, which is likely to cause the clamping part 600 to fail to clamp the upper strip section 510 or have an error in the clamping position, resulting in errors in the formed product. The setting of the pre-positioning assembly 400 can lift the free end of the punched upper strip section 510 to a predetermined position (that is, to level the movement path of the clamping part 600), which is convenient for the correct clamping of the clamping part 600.
[0037] In the embodiments of the present application, the bending die 100 further includes an ejecting member 130. The profiling member 120 has a profiling groove for shaping the upper strip section 510. The ejecting member 130 is used to eject the upper strip section 510 on the profiling groove. Specifically, the ejecting member 130 is a second air cylinder. The air cylinder rod of the second air cylinder has a ejecting rod 131, and the ejecting rod 131 can enter the profiling groove. Through the cooperation of the second air cylinder and the ejecting rod 131, it can effectively prevent the upper strip section 510 from being stuck in the profiling groove.
[0038] In some other embodiments, the installation platform is further provided with a transfer member 300, and the transfer member 300 is used to transfer the bent upper strip section 510. Specifically, after the upper strip section 510 is bent, the transfer member 300 takes out the upper strip section 510 from the profiling member 120 and transfers it to a designated position, so that the robot in the next process can correctly receive and transfer it, which is convenient for the construction of automated production. Among them, the transfer member 300 is erected above the bending die 100.
[0039] Specifically, as Figure 5 and Figure 6 shown, the transfer member 300 includes a first module 310, a second module 320 and a third module 330. The third driving block of the third module 330 is provided with a clamping jaw 340 for clamping the upper strip section 510. The third driving block can perform linear reciprocating motion in the horizontal direction. The third module 330 is fixed to the first driving block of the second module 320, and the first driving block can perform linear reciprocating motion in the horizontal direction. The second module 320 is fixed to the second driving block 311 of the first module 310, and the second driving block 311 can perform linear reciprocating motion in the vertical direction. The moving directions of the first driving block and the second driving block 311 are perpendicular.
[0040] Specifically, the transfer member 300 includes a mounting frame 301, and the first module 310 is fixed to the mounting frame 301. Among them, the first module 310 includes a third air cylinder and a second driving block 311. The third air cylinder is fixed to the mounting frame 301, and the second driving block 311 is slidably arranged on the mounting frame 301 through a guide rail slider structure, so that the second driving block 311 can move in the vertical direction. The second driving block 311 is connected to the air cylinder rod of the third air cylinder; the second module 320 is a fourth air cylinder, the fourth air cylinder has a guide rod, the first driving block is fixed to the air cylinder rod of the fourth air cylinder, the third module 330 is a fifth air cylinder, and the clamping jaw 340 is a parallel air jaw, and the parallel air jaw is fixed to the air cylinder rod of the fifth air cylinder.
[0041] In use, the first module 310 lowers the jaw 340 to a position where it can grip the upper strip 510. Then, the second module 320 and the second cylinder act simultaneously. Through the cooperation of the second module 320 and the ejector rod 131, the upper strip 510 is taken out from the profiling groove. Then, the first module 310 rises so that the obtained upper strip 510 reaches the specified position. Then, the third module 330 transports the upper strip 510 to a specified position in the horizontal direction for the pick-and-place robot in the next process to pick up the material.
[0042] In some embodiments, a retractable positioning pin 350 is further provided on the mounting bracket 301. The extension and retraction of the positioning pin 350 is driven by a sixth cylinder. The positioning pin 350 is used to position the rated height of the second driving block 311 so that the pick-and-place robot in the next process can pick up the material more accurately.
[0043] The embodiments of the present application have been described in detail above in conjunction with the accompanying drawings. However, the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present application.
