[0018] A method for machining a concealed rail, using the concealed rail machining machine, comprises the following machining steps:

[0019] Step 1: Punching the stop. The controller controls the operation of the workpiece conveyor belt, automatic material bridge, and punching the stop mold processing component, so that the semi-finished middle rail part is conveyed by the workpiece conveyor belt to the feeding positioning station. The workpiece conveying station moves up and down and back and forth with the automatic material bridge to drive the semi-finished middle rail part into the punching stop mold processing component. The punching processing push component of the punching stop mold processing component moves to push the semi-finished middle rail part into the lower punching stop mold group for clamping and positioning. The upper punching stop mold punch group moves to punch the semi-finished middle rail part through stamping to complete the punching stop. Then the upper punching stop mold punch group resets, and the punching stop workpiece reset push component moves to push the semi-finished middle rail part away from the lower punching stop mold group and into the corresponding workpiece conveying station. The automatic material bridge moves to move the semi-finished middle rail part to the next processing step.

[0020] The second step is head shaping and chamfering. The controller controls the automatic material bridge to reset and the head shaping mold processing components to move. The head pusher pushes the middle rail semi-finished part into the head shaping and chamfering lower mold assembly for clamping and positioning. The head shaping and chamfering upper mold punch assembly moves to shape and chamfer the head of the middle rail semi-finished part through upsetting. Then the head shaping and chamfering upper mold resets, the head pusher resets, and pushes the middle rail semi-finished part away from the head shaping and chamfering lower mold assembly and into the corresponding workpiece conveying station.

[0023] Step 5: Edge punching. The controller controls the automatic material bridge to reset and controls the edge punching processing components to move, causing the edge punching pusher to move and push the middle rail semi-finished part into the lower edge punching die for clamping and positioning. The upper edge punching die punch group moves, punching the edge directly to complete the edge punching round hole. Then the upper edge punching die punch group resets, and the edge punching reset pusher moves to push the middle rail semi-finished part away from the lower edge punching die and into the corresponding workpiece conveying station. The automatic material bridge moves to move the middle rail semi-finished part to the next processing step.

[0024] Step 6: Straight edge budding. The controller controls the automatic material bridge to reset and controls the straight edge budding processing components to move, causing the straight edge budding pusher to move and push the middle rail semi-finished part into the lower straight edge budding module for clamping and positioning. The upper straight edge budding die needle-pulling group moves, using the needle to punch straight along the straight edge to complete the straight edge budding. Then, the upper straight edge budding die needle-pulling group resets, and the straight edge budding reset pusher moves to push the middle rail semi-finished part away from the lower straight edge budding module and into the corresponding workpiece conveying station. The automatic material bridge moves to transfer the middle rail semi-finished part to the next processing step.

[0025] Step 7: 180-degree flip, the controller controls the automatic material bridge to reset and controls the second flipping component to move, the second positioning pushers on the left and right sides of the frame move to position and clamp the two ends of the middle rail semi-finished part, the second rotation drive source moves to drive the middle rail semi-finished part to rotate 180 degrees, then the second rotation drive source stops working, the second positioning pushers reset, the automatic material bridge moves to move the middle rail semi-finished part to the next processing step;

[0026] Step 8: Straight edge punching. The controller controls the automatic material bridge to reset and controls the straight edge punching processing parts to move, causing the straight edge punching pusher to move and push the middle rail semi-finished part into the lower straight edge punching die for clamping and positioning. The upper straight edge punching die punch group moves, punching straight along the straight edge to complete the straight edge punching of the round hole. Then the upper straight edge punching die punch group resets, and the straight edge punching reset pusher moves to push the middle rail semi-finished part away from the lower straight edge punching die and into the corresponding workpiece conveying station. The automatic material bridge moves to move the middle rail semi-finished part to the next processing step.

[0027] Step 9: Edge trimming and budding. The controller controls the automatic material bridge to reset and controls the edge trimming and budding processing components to move the edge trimming and budding pusher to push the middle rail semi-finished part into the lower edge trimming and budding module for clamping and positioning. The upper edge trimming and budding die needle-pulling group moves, using the needles to push straight towards the edge to complete the edge trimming and budding. Then, the upper edge trimming and budding die needle-pulling group resets, and the edge trimming and budding reset pusher moves to push the middle rail semi-finished part away from the lower edge trimming and budding module and into the corresponding workpiece conveying station. The automatic material bridge moves to transfer the middle rail semi-finished part to the next processing step.

[0028] Step 10: 90-degree flip, the controller controls the automatic material bridge to reset and controls the third flipping component to move, the third positioning pushers on the left and right sides of the frame move to position and clamp the two ends of the middle rail semi-finished part, the third rotation drive source moves to drive the middle rail semi-finished part to rotate 90 degrees, then the third rotation drive source stops working, the third positioning pusher resets, the automatic material bridge moves to move the middle rail semi-finished part to the next processing step;

[0029] Step 11: Punching the lower stop point. The controller controls the automatic material bridge to reset and controls the lower stop point processing components to move. The lower stop point processing pusher moves to push the middle rail semi-finished part into the lower stop point lower die assembly for clamping and positioning. The lower stop point upper die punch assembly moves, and the tearing hook punch of the lower stop point upper die punch completes the punching of the lower stop point. Subsequently, the lower stop point upper die punch assembly resets, and the lower stop point workpiece reset pusher moves to push the middle rail semi-finished part away from the lower stop point lower die assembly and into the corresponding workpiece conveying station. The automatic material bridge moves to move the middle rail semi-finished part to the next processing step.

[0030] Step 12: Punching the side hook. The controller controls the automatic material bridge to reset and controls the side hook processing component to move. The side hook processing pusher of the side hook processing component moves to push the middle rail semi-finished part into the lower side hook die assembly for clamping and positioning. The upper side hook die punch assembly moves to complete the punching of the side hook through the side hook punch of the upper side hook die punch assembly. Then the upper side hook die punch assembly resets. The side hook workpiece reset pusher moves to push the middle rail semi-finished part away from the lower side hook die assembly and into the corresponding workpiece conveying station. The automatic material bridge moves to move the middle rail semi-finished part to the next processing step.

[0031] Step 13: Punching the upper stop point. The controller controls the automatic material bridge to reset and controls the upper stop point processing component to move. The upper stop point processing pusher of the upper stop point processing component moves to push the semi-finished middle rail part into the lower die assembly of the upper stop point for clamping and positioning. The upper die punch assembly of the upper stop point moves, and the tearing hook punch of the upper die punch assembly completes the punching of the upper stop point. Subsequently, the upper die punch assembly of the upper stop point resets, and the upper stop point processing pusher resets, pushing the semi-finished middle rail part away from the lower die assembly of the upper stop point and into the corresponding workpiece conveyor station. The automatic material bridge moves to move the finished middle rail part to the discharge positioning station so that it can be conveyed to the workpiece conveyor belt for the next processing step.

[0032] The advantages of this invention are as follows: the use of this structure for the hidden rail processing machine and the processing method of this machine can solve the bottleneck of the middle rail in the processing of hidden rails, and effectively improve the quality stability, mold safety and continuous processing productivity.

[0055] Reference Figures 1 to 6 As shown, a method for processing a hidden rail, using the aforementioned hidden rail processing machine, comprises the following processing steps:

[0056] Step 1: Punching the stop. Controller 15 controls the operation of the workpiece conveyor belt, automatic feed bridge 16, and punching stop mold processing component 2, causing the semi-finished middle rail part to be conveyed by the workpiece conveyor belt to the feeding positioning station 17. The workpiece conveying station moves up and down and back and forth with the automatic feed bridge 16 to drive the semi-finished middle rail part into the punching stop mold processing component 2. The punching processing pusher of the punching stop mold processing component 2 pushes the semi-finished middle rail part into the lower punching stop mold 23 for clamping and positioning. The upper punching stop punch assembly 22 operates, punching the semi-finished middle rail part to complete the punching stop through stamping. Subsequently, the upper punching stop punch assembly 22 resets, and the punching stop workpiece reset pusher 24 operates, pushing the semi-finished middle rail part away from the lower punching stop mold 23 and into the corresponding workpiece conveying station. The automatic feed bridge 16 operates to move the semi-finished middle rail part to the next processing step.

[0057] The second step: head shaping and chamfering. Controller 15 controls the automatic material bridge 16 to reset and the head shaping mold processing component 3 to operate. The head pusher 31 pushes the mid-rail semi-finished part into the head shaping and chamfering lower die 33 for clamping and positioning. The head shaping and chamfering upper die punch assembly 32 operates, shaping and chamfering the head of the mid-rail semi-finished part through upsetting. Subsequently, the head shaping and chamfering upper die resets, the head pusher 31 resets, pushing the mid-rail semi-finished part away from the head shaping and chamfering lower die 33 and into the corresponding workpiece conveying station. The automatic material bridge 16 operates to move the mid-rail semi-finished part to the next processing step.

[0058] The third step: tail shaping and chamfering. Controller 15 controls the automatic material bridge 16 to reset and controls the tail shaping mold processing component 4 to move. The tail pusher 41 of the tail shaping mold processing component 4 moves, pushing the middle rail semi-finished part into the tail shaping lower mold assembly 43 for clamping and positioning. The tail shaping upper mold punch assembly 42 moves, completing the tail shaping by side-tapping the tail shaping clamping block. Subsequently, the tail shaping upper mold punch assembly 42 resets, and the tail shaping reset pusher 44 moves, pushing the middle rail semi-finished part away from the tail shaping lower mold assembly 43 and into the corresponding workpiece conveying station. The automatic material bridge 16 moves, so that the middle rail semi-finished part is transferred to the next processing step.

[0059] Step 4: A 90-degree flip occurs. Controller 15 controls the automatic feed bridge 16 to reset and controls the first flipping component 5 to move. The first positioning pushers 51 on both sides of the frame 1 move to clamp the two ends of the mid-rail semi-finished part. The first rotation drive source 52 moves to rotate the mid-rail semi-finished part 90 degrees. Then, the first rotation drive source 52 stops working, the first positioning pushers 51 reset, and the automatic feed bridge 16 moves to transfer the mid-rail semi-finished part to the next processing step.

[0060] Step 5: Edge punching. Controller 15 controls the automatic material bridge 16 to reset and controls the edge punching processing component 6 to move, causing the edge punching pusher 61 to move, pushing the mid-rail semi-finished part into the edge punching lower die 63 for clamping and positioning. The edge punching upper die punch assembly 62 moves, punching the edge directly to complete the edge punching round hole. Then, the edge punching upper die punch assembly 62 resets, and the edge punching reset pusher 64 moves, pushing the mid-rail semi-finished part away from the edge punching lower die 63 and into the corresponding workpiece conveying station. The automatic material bridge 16 moves, so that the mid-rail semi-finished part is transferred to the next processing step.

[0061] Step 6: Straight edge budding. Controller 15 controls the automatic material bridge 16 to reset and controls the straight edge budding processing component 7 to activate the straight edge budding pusher 71, pushing the mid-rail semi-finished part into the lower straight edge budding module 73 for clamping and positioning. The upper straight edge budding die needle-pulling assembly 72 activates, using the needle to push straight along the straight edge to complete the straight edge budding. Subsequently, the upper straight edge budding die needle-pulling assembly 72 resets, and the straight edge budding reset pusher 74 activates, pushing the mid-rail semi-finished part away from the lower straight edge budding module 73 and into the corresponding workpiece conveying station. The automatic material bridge 16 activates to move the mid-rail semi-finished part to the next processing step.

[0062] Step 7: A 180-degree flip occurs. Controller 15 controls the automatic feed bridge 16 to reset and controls the second flipping component 8 to move. The second positioning pushers 81 on both sides of the frame 1 move to clamp the two ends of the mid-rail semi-finished part. The second rotation drive source 82 moves to rotate the mid-rail semi-finished part 180 degrees. Then, the second rotation drive source 82 stops working, the second positioning pushers 81 reset, and the automatic feed bridge 16 moves to transfer the mid-rail semi-finished part to the next processing step.

[0063] Step 8: Straight edge punching. Controller 15 controls the automatic material bridge 16 to reset and controls the straight edge punching processing component 9 to move, causing the straight edge punching pusher 91 to move, pushing the middle rail semi-finished part into the straight edge punching lower die 93 for clamping and positioning. The straight edge punching upper die punch assembly 92 moves, punching straight along the straight edge to complete the straight edge punching of the round hole. Then, the straight edge punching upper die punch assembly 92 resets, and the straight edge punching reset pusher 94 moves, pushing the middle rail semi-finished part away from the straight edge punching lower die 93 and into the corresponding workpiece conveying station. The automatic material bridge 16 moves, so that the middle rail semi-finished part is transferred to the next processing step.

[0064] Step 9: Edge trimming and budding. Controller 15 controls the automatic material bridge 16 to reset and controls the edge trimming and budding processing component 10 to activate, causing the edge trimming and budding pusher 101 to push the mid-rail semi-finished part into the edge trimming and budding lower module 103 for clamping and positioning. The edge trimming and budding upper die needle-pulling assembly 102 activates, using the needle to push directly towards the edge to complete the edge trimming and budding. Subsequently, the edge trimming and budding upper die needle-pulling assembly 102 resets, and the edge trimming and budding reset pusher 104 activates, pushing the mid-rail semi-finished part away from the edge trimming and budding lower module 103 and into the corresponding workpiece conveying station. The automatic material bridge 16 activates to move the mid-rail semi-finished part to the next processing step.

[0065] Step 10: A 90-degree rotation occurs. Controller 15 controls the automatic feed bridge 16 to reset and controls the third rotation component 11 to move. The third positioning pushers 111 on both sides of the frame 1 move to clamp the two ends of the mid-rail semi-finished part. The third rotation drive source 112 moves to rotate the mid-rail semi-finished part 90 degrees. Then, the third rotation drive source 112 stops working, the third positioning pusher 111 resets, and the automatic feed bridge 16 moves to transfer the mid-rail semi-finished part to the next processing step.

[0066] Step 11: Punching the lower stop point. Controller 15 controls the automatic feed bridge 16 to reset and controls the lower stop point processing component 12 to operate. The lower stop point processing pusher 121 of the lower stop point processing component 12 operates, pushing the mid-rail semi-finished part into the lower stop point die assembly 123 for clamping and positioning. The lower stop point upper die punch assembly 122 operates, using the tearing hook punch of the lower stop point upper die punch to complete punching the lower stop point. Subsequently, the lower stop point upper die punch assembly 122 resets, and the lower stop point workpiece reset pusher 124 operates, pushing the mid-rail semi-finished part away from the lower stop point die assembly 123 and into the corresponding workpiece conveying station. The automatic feed bridge 16 operates to move the mid-rail semi-finished part to the next processing step.

[0067] Step 12: Punching the side hook. Controller 15 controls the automatic material bridge 16 to reset and controls the side hook processing component 13 to operate. The side hook processing pusher 131 of the side hook processing component 13 operates, pushing the mid-rail semi-finished part into the lower side hook die 133 for clamping and positioning. The upper side hook punch assembly 132 operates, completing the side hook punching through the side hook punch of the upper side hook punch assembly 132. Subsequently, the upper side hook punch assembly 132 resets, and the side hook workpiece reset pusher 134 operates, pushing the mid-rail semi-finished part away from the lower side hook die 133 and into the corresponding workpiece conveying station. The automatic material bridge 16 operates to move the mid-rail semi-finished part to the next processing step.

[0068] Step 13: Punching the upper stop point. Controller 15 controls the automatic material bridge 16 to reset and controls the upper stop point processing component 14 to operate. The upper stop point processing pusher 141 of the upper stop point processing component 14 operates, pushing the semi-finished middle rail part into the lower upper stop point die 143 for clamping and positioning. The upper stop point upper die punch assembly 142 operates, using its tearing hook punch to complete punching the upper stop point. Subsequently, the upper stop point upper die punch assembly 142 resets, and the upper stop point processing pusher 141 resets, pushing the semi-finished middle rail part away from the lower upper stop point die 143 and into the corresponding workpiece conveying station. The automatic material bridge 16 operates, so that the finished middle rail part is moved to the discharge positioning station 18 for conveying to the workpiece conveyor belt for the next processing step.
