[0013] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention.

[0014] like Figures 1 to 8The present invention includes a hole counting mechanism, a trimming system, a cutting mechanism and a frame, wherein a hole counting station 1, a trimming station 2 and a cutting station 3 are arranged on the frame in sequence, and the hole counting mechanism, the trimming system and the cutting mechanism are arranged on the hole counting station 1, the trimming station 2 and the cutting station 3 in sequence according to the length of the workpiece. A roller 4 is arranged on the frame, and the profile to be processed passes through the roller 4, and the profile moves from the hole counting station 1 to the cutting station 3. After the hole counting station 1 detects that the profile is in place, the trimming station 2 and the cutting mechanism are operated in sequence; the processes of trimming and forming can be realized, and the trimming and forming processes can be completed in one processing equipment, thereby saving the disadvantages caused by transportation between multiple processes.

[0015] The trimming system includes two groups of trimming mechanisms that are symmetrically arranged on the left and right, and each group of trimming mechanisms includes a trimming static knife 5, a trimming movable knife 6, and a lifting cylinder 7. Since the curling edge is arranged obliquely on the workpiece, in order to cooperate with the curling edge of the workpiece, the trimming static knife 5 is obliquely fixed above the frame, and the setting angle of the trimming static knife 5 matches the curling angle of the profile. The trimming movable knife 6 is arranged to match the trimming static knife 5. The lifting cylinder 7 drives the trimming movable knife 6 to move obliquely back and forth, and the trimming edge of the profile passes between the trimming static knife 5 and the trimming movable knife 6. Through the above arrangement, the profile is fed from the hole counting mechanism, passes through the trimming station 2 and the cutting station 3 in sequence, and the trimming edge of the profile is located between the trimming static knife 5 and the trimming movable knife 6. The trimming edge of the profile can be cut off by the action of the movable knife to complete the trimming.

[0016] A lifting mechanism is also provided, which includes a guide assembly 8, a lifting plate 9, a pull-back cylinder 10 and a lifting spring 11. The roller 4 is arranged on the lifting plate 9, and the pull-back cylinder 10 and the lifting spring 11 are arranged at the bottom of the lifting plate 9. The two ends of the lifting spring 11 are respectively connected to the frame and the bottom of the lifting plate 9. The cylinder seat of the pull-back cylinder 10 is fixed on the frame, and the cylinder rod is connected to the lifting plate 9, and drives the lifting plate 9 to move up and down. After the workpiece is in place, the lifting spring 11 pushes the workpiece, and the lifting spring 11 lifts the workpiece to the bottom surface of the edge-cutting static knife 5. Then the moving knife moves once to complete the edge-cutting. After that, the pull-back cylinder 10 contracts, and the lifting plate 9 is retracted to be flush with the roller 4, and then the roller 4 drives the workpiece to continue to move to the lower station. The combined force generated by the lifting spring 11 and the pull-back cylinder 10 causes the lifting plate 9 to move up and down, ensuring the stability of the lifting action. In order to ensure that the lifting plate 9 can be lifted and lowered along a fixed track, a guide assembly 8 is also provided, the guide assembly 8 includes a guide column 12 and a guide block 13, one side of the lifting plate 9 is fixedly connected to the guide block 13, the guide column 12 is longitudinally arranged on the frame, and the guide block 13 moves longitudinally along the guide column 12. The stability of the lifting plate 9 when it is lifted and lowered is ensured, thereby ensuring that the workpiece can accurately fit the edge trimming static knife 5, and ensuring the edge trimming quality.

[0017] In order to limit the lifting height of the lifting spring 11 and ensure that the workpiece on the lifting plate 9 can just fit the edge trimming knife 5, a number of limit columns 16 are also provided. The bottom end of the limit column 16 is fixed on the frame. The lifting plate 9 is provided with a limit hole. The position of the limit hole matches the limit column 16. The top of the limit column 16 passes through the limit hole. The top of the limit column 16 is provided with a baffle 17. The lifting spring 11 is sleeved outside the sliding column. The lifting spring 11 pushes the lifting plate 9 against the bottom surface of the baffle 17. The height of the baffle 17 is higher than the working height of the cutting station 3. The position of the baffle 17 avoids the position of the profile transfer. The setting height of the baffle 17 is set according to the height of the workpiece and the edge trimming knife 5. It prevents the workpiece from hitting the edge trimming knife 5 and also ensures the stability of the workpiece lifting height.

[0018] A pressure wheel 18 and a limiting wheel 19 are also provided on both sides of the edge scraping static knife 5. The bottom end of the pressure wheel 18 is flush with the edge scraping static knife 5, which can prevent the workpiece from hitting the static knife and extend the service life of the edge scraping static knife 5. The limiting wheels 19 are arranged in pairs on the lifting plate 9. The profile passes through the middle of the limiting wheels 19, and the limiting wheels 19 abut against both sides of the profile. This ensures that the workpiece is stably transmitted on the rack to prevent deviation.

[0019] The cutting mechanism includes a cutting tool, a lifting pressure block 22 and a cutting cylinder 23. The pressure block 22 is arranged beside the cutting tool. An actuating cylinder is arranged on the pressure block 22. The actuating cylinder drives the pressure block 22 to lift and lower. The cutting tool includes a moving cutting knife and a static cutting knife. The static cutting knife is fixed on the cutting station 3. The cutting cylinder 23 is fixed above the static cutting knife. The cutting cylinder 23 drives the moving cutting knife to move toward the static cutting knife. In order to ensure the stability of the workpiece during the cutting process, a pressing groove 24 matching the shape of the processed profile is provided on the bottom surface of the pressure block 22. Before the moving cutting knife cuts, the pressure block 22 is pressed on the workpiece to ensure that the workpiece will not move during the cutting process, thereby improving the quality of the cutting operation of the end face of the workpiece.

[0020] The hole counting mechanism includes an infrared sensor 25 and a mounting frame 26. The infrared sensor 25 is arranged on the frame through the mounting frame 26 and is located above the conveying route of the profile. Position holes 15 are pre-opened on the profile. The infrared sensor 25 identifies the position of the position holes 15. The infrared sensor 25 of the hole counting mechanism senses the position of the workpiece and provides an action signal for the edge trimming mechanism and the cutting mechanism.

[0021] The working process is as follows: the infrared sensor 25 of the hole counting mechanism senses whether the position hole of the workpiece is in place, and provides an action signal for the trimming mechanism and the cutting mechanism. The profile to be processed passes through the hole counting station, the trimming station 2 and the cutting station 3 in sequence, and the curling edge of the profile is located between the trimming static knife 5 and the trimming movable knife 6. After the hole counting station 1 detects that the position hole 15 of the profile is in place, the roller stops rotating, the profile stops moving, and the lifting spring 11 pushes the lifting plate. The lifting spring 11 lifts the workpiece on the lifting plate to fit the bottom surface of the trimming static knife 5. Then, the curling edge of the profile can be cut off by the trimming movable knife action to complete the trimming. After that, the pull-back cylinder 10 contracts, and the lifting plate 9 is lowered back to the level of the roller 4. Then, the roller 4 drives the workpiece to continue to move to the cutting station 3 for trimming. The trimming movable knife cuts and shapes the end of the profile to complete the processing of a workpiece. Then, the lifting plate 9 lifts the profile that has just arrived at the trimming station 2 again to trim the edge, and the above actions are repeated.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
