[0056] 5) Conveyor No. 2 will transport intermediate component No. 4 to hydraulic press No. 3 in multiple steps at a certain step length;

[0057] 6) The No. 3 hydraulic press first hydraulically presses the No. 4 intermediate part into the No. 5 transition part, and then through multiple segmented hydraulic presses, it is formed into a T-shaped hollow elevator guide rail semi-finished product.

[0058] Beneficial Effects: Compared with the prior art, the features of this invention are: 1. The entire process of conveying the blank, the transition parts, the intermediate parts, and the hydraulic forming is fully automated; 2. Multiple segmented forming allows this production line to be suitable for forming T-shaped hollow elevator guide rails of any length, expanding the application range of this assembly line; 3. During the roller conveying of the T-shaped hollow elevator guide rail blank, the roller presses the blank with constant pressure, avoiding both uneven roller conveying due to insufficient blank thickness and uneven blank thickness. 4. Excessive blank thickness can cause the rollers to crush the blank or prevent it from being rolled at all; 5. During the rolling process of the T-shaped hollow elevator guide rail blank, the two sets of guide wheel groups, under the action of spring force, always clamp the blank in the middle position of the rolling component, which avoids tilting during rolling due to insufficient blank width and prevents rolling failure due to excessive blank width; 6. Under the action of the spring force of the No. 1 telescopic spring, the No. 1 upper mold assembly of the No. 1 hydraulic press automatically adjusts the centering of the T-shaped hollow elevator guide rail blank, improving the forming accuracy.

Detailed Implementation

[0106] To more clearly illustrate the technical solution of the present invention, the technical solution of the present invention will be further described in detail below with reference to the accompanying drawings:

[0107] like Figure 1 , Figure 23-29 As shown, the T-shaped hollow elevator guide rail forming production line of the present invention includes conveyor 0, hydraulic press 1, conveyor 2, hydraulic press 3, conveyor 4 and hydraulic press 5.

[0108] The No. 0 conveyor, No. 1 hydraulic press, No. 1 conveyor, No. 2 hydraulic press, No. 3 hydraulic press, No. 4 hydraulic press, and No. 3 hydraulic press are arranged in a straight line.

[0109] Hydraulic press 1 first hydraulically presses the T-shaped hollow elevator guide rail blank A, which is rolled from conveyor 0, into intermediate part B, and then into intermediate part C through multiple segmented hydraulic presses. Conveyor 2 first conveys intermediate part C to hydraulic press 3 at certain step lengths. Hydraulic press 3 first hydraulically presses intermediate part C into intermediate part D, and then into intermediate part E through multiple segmented hydraulic presses. Conveyor 4 second conveys intermediate part E to hydraulic press 5 at certain step lengths. Hydraulic press 5 first hydraulically presses intermediate part E into intermediate part F, and then into semi-finished T-shaped hollow elevator guide rail G through multiple segmented hydraulic presses.

[0110] like Figure 2As shown, the No. 0 conveyor 0 comprises a No. 0 roller conveyor assembly 01, a No. 0 conveyor support assembly 02, and a No. 0 dual-axis cylinder 03. The No. 0 roller conveyor assembly 01 is mounted vertically on the No. 0 guide rod 022 of the No. 0 conveyor support assembly 02 via its flange-type linear bearing 011. The two No. 0 dual-axis cylinders 03 are respectively installed in the left through hole 021.1 and the right through hole 021.2 on the top surface of the No. 0 conveyor support assembly 02. The ends of the piston rods of the two No. 0 dual-axis cylinders 03 are connected to the No. 0 roller conveyor assembly 01. When the piston rods of the two No. 0 dual-axis cylinders 03 extend or retract, they drive the No. 0 roller conveyor assembly 01 to move vertically along the No. 0 guide rod 022.

[0111] like Figure 3-5 As shown, the No. 0 roller conveyor assembly 01 includes a roller conveyor plate 012, rollers 013, double sprockets 014, and a roller conveyor motor 015. Several rollers 013 are mounted in a linear array on the bottom surface of the roller conveyor plate 012 via No. 0 bearing 017. A double sprocket 014 is mounted at one end of each roller 013. The roller conveyor motor 015 is mounted on the top surface of the roller conveyor plate 012. A sprocket is mounted on the output shaft of the roller conveyor motor 015. The double sprockets 014 mounted at one end of each roller 013 are connected in pairs by chains (not shown in the figure). The sprocket mounted on the output shaft of the roller conveyor motor 015 is connected to the double sprocket 014 mounted on one of the rollers 013 by chains (not shown in the figure). When the output shaft of the roller conveyor motor 015 rotates, it drives the roller 013 to rotate via chain drive. Four flanged linear bearings 011 are installed in a linear array at the four corners of the roller conveyor plate 012, and four pressure rods 016 are installed in a linear array on the bottom surface of the roller conveyor plate 012.

[0112] like Figure 6-8 As shown, the No. 0 conveyor bracket assembly 02 includes a No. 0 bracket 021, a No. 0 guide rod 022, and a guide wheel set 023;

[0113] Four guide rods 022 are linearly arrayed on the top surface of bracket 021. Two sets of guide wheel assemblies 023 are movably mounted in grooves 021.2 and 021.4 of bracket 021 via horizontal telescopic springs 024. The horizontal telescopic springs 024, installed between spring hole 021.3 and spring hole 0231.1, drive the guide wheel assemblies 023 to move horizontally in groove 021.2 of bracket 021, thereby changing the distance between the two sets of guide wheel assemblies 023 to accommodate the rolling of blanks of different widths.

[0114] like Figure 9-10 As shown, the guide wheel assembly 023 includes an open slot 0231, a vertical telescopic spring 0232, a long strip plate 0233, a guide wheel 0234, and a strip-shaped limiting plate 0235;

[0115] The long strip plate 0233 is movably mounted in the opening slot 0231 via a vertical telescopic spring 0232. Several guide wheels 0234 are mounted in a linear array on the long strip plate 0233 via their rotating shafts. The strip-shaped limiting plate 0235 is mounted on one end of the rotating shaft of the guide wheel 0234. When the vertical telescopic spring 0232 is compressed, the long strip plate 0233 moves downward, thereby driving the guide wheel 0234 mounted on it and the strip-shaped limiting plate 2235 mounted on one end of the rotating shaft of the guide wheel 0234 to move downward, changing the distance between the lower surface of the strip-shaped limiting plate 0235 and the top surface of the bracket 021 to accommodate the conveying of blanks of different thicknesses.

[0116] When the blank reaches the No. 0 conveyor, the piston rods of the two No. 0 dual-shaft cylinders 03 retract, driving the No. 0 rolling assembly 01 to move down along the No. 0 guide rod 022. The roller 013 presses the blank with constant pressure. At the same time, the four pressure rods 016 installed on the bottom surface of the rolling plate 012 move down, pressing the guide wheel set 023. The guide wheel set 023 moves down, so that the distance between the lower surface of the strip limit plate 0235 and the top surface of the No. 0 bracket 221 is equal to the thickness of the blank. Under the combined action of the thrust of the guide wheel set 023 on both sides of the blank and the spring force of the horizontal telescopic spring 024, the distance between the two sets of guide wheel sets 023 is adaptively adjusted according to the width of the blank, thereby reliably locking the blank between the two sets of guide wheel sets 023. The rolling motor 015 starts, driving the blank to roll reliably and smoothly towards the No. 1 hydraulic press 1.

[0117] like Figure 11 As shown, the No. 1 hydraulic press 1 includes a No. 1 bed 11, a No. 1 clamping plate 12, a No. 1 upper mold assembly 13, a No. 1 linear bearing 14, a No. 1 guide rod 15, a No. 1 hydraulic cylinder 16, and a No. 1 lower mold 17. A rubber layer with several protrusions is adhered to the bottom surface of the No. 1 clamping plate 12 to increase the coefficient of friction. Three No. 1 hydraulic cylinders 16 are mounted on the top surface of the No. 1 bed 11, with their hydraulic rods passing through a through hole in the middle of the top surface of the No. 1 bed 11. Four No. 1 linear bearings 14 and No. 1 guide rods 15 are linearly arrayed on the top surface of the No. 1 bed 11. The flange end of the No. 1 linear bearing 14 is fixedly connected to the top surface of the No. 1 upper mold assembly 13. The top surface of the No. 1 upper mold assembly 13 is also connected to the end of the hydraulic rod of the No. 1 hydraulic cylinder 16 installed in the middle of the top surface of the No. 1 bed 11. The No. 1 lower mold 17 is installed on the worktable of the No. 1 bed 11. The hydraulic rods of the two No. 1 hydraulic cylinders 16 installed in the front and rear positions of the top surface of the No. 1 bed 11 pass through the through holes opened in the front and rear positions of the top surface of the No. 1 bed 11 and the through hole 131.1 on the top surface of the No. 1 upper mold assembly 13, and their ends are fixedly connected to the top surface of the No. 1 clamping plate 12.

[0118] When the hydraulic rod of hydraulic cylinder 16, located in the middle of the top surface of bed 11, extends or retracts, it drives upper mold assembly 13 to move up and down. When the hydraulic rods of two hydraulic cylinders 16, located at the front and rear positions of the top surface of bed 11, extend or retract, they drive clamping plate 12 to move up and down. Lower mold 17 is mounted on the worktable of bed 11.

[0119] like Figure 12-14 As shown, the first upper mold assembly 13 includes a first upper mold body 131, an adjustment block 132, a first telescopic spring 134, and a first shaft spring retaining ring 133;

[0120] An extension shaft is machined on one side of the adjustment block 132, and a rounded corner is machined on the lower end of the other side of the adjustment block 132. A telescopic spring 134 is fitted on the extension shaft on one side of the adjustment block 132, and then passes through the through holes on both sides of the upper mold body 131. The adjustment block 132 is installed at the opening on the lower side of the upper mold body 131 through the spring retaining ring 133 on the first shaft.

[0121] The working process of hydraulic press No. 1 is as follows:

[0122] 1) When the upstream T-shaped hollow elevator guide rail blank A moves to the No. 1 hydraulic press 1, the hydraulic rod of the No. 1 hydraulic cylinder 16, which is installed in the middle position on the top surface of the No. 1 bed 11, extends and drives the No. 1 upper mold assembly 13 to move down. The adjusting block 132 gradually jams the T-shaped hollow elevator guide rail blank A. Under the action of the spring force of the No. 1 telescopic spring 134, the T-shaped hollow elevator guide rail blank A automatically adjusts its position so that the longitudinal symmetrical center line of the T-shaped hollow elevator guide rail blank A coincides with the longitudinal symmetrical center line of the No. 1 lower mold 17.

[0123] 2) The hydraulic rods of the two hydraulic cylinders 16 installed at the front and rear positions on the top surface of the first bed 11 extend out, driving the first clamping plate 12 to move down, and the first clamping plate 12 reliably presses the T-shaped hollow elevator guide rail blank A onto the first lower mold 17.

[0124] 3) The hydraulic rod of the hydraulic cylinder 16, which is installed in the middle position on the top surface of the bed 11, continues to extend, driving the upper mold assembly 13 to continue to move down, hydraulically transforming the T-shaped hollow elevator guide rail blank A into the transition piece B.

[0125] 4) The hydraulic rod of the No. 1 hydraulic cylinder 16, which is installed in the middle position on the top surface of the No. 1 bed 11, retracts, causing the No. 1 upper mold assembly 13 to move upward. The hydraulic rods of the two No. 1 hydraulic cylinders 16, which are installed in the front and rear positions on the top surface of the No. 1 bed 11, retract. The No. 1 clamping plate 12 moves upward. The No. 1 clamping plate 12 no longer presses the No. 1 transition piece B on the No. 1 lower mold 17. The No. 1 transition piece B moves forward a certain distance.

[0126] 5) Repeat steps 2-4 until the T-shaped hollow elevator guide rail blank A is hydraulically molded into intermediate part C.

[0127] like Figure 15 As shown, the No. 1 conveyor 2 includes a No. 1 platform 21, a No. 1 gantry frame 22, a No. 1 rodless cylinder 23, a No. 1 guide rail 24, a robotic arm 25, and a No. 1 slider 26;

[0128] Two No. 1 gantry frames 22 are installed at the front and rear ends of No. 1 platform 21. No. 1 rodless cylinder 23 is installed on the two No. 1 gantry frames 22. Two No. 1 guide rails 24 are installed parallel to each other on the protrusions on the top surface of No. 1 platform 21. The robot arm 25 is installed on the No. 1 guide rail 24 through No. 1 slider 26 and is fixedly connected to the slider of No. 1 rodless cylinder 23.

[0129] When the slider of rodless cylinder 23 moves, it drives the robotic arm 25 to move along guide rail 24.

[0130] Furthermore, such as Figure 16 As shown, the robotic arm 25 includes a crossbeam 251, a gripper 252, and a tension spring 253. The gripper 252 is movably mounted in a square through slot of the crossbeam 251 via the tension spring 253. The lower end of the gripper 252 is an electromagnetic chuck. When the second intermediate part C reaches the robotic arm 25, the electromagnetic chuck at the lower end of the gripper 252 is energized and attracts the vertical sides of the second intermediate part C. The slider of the first rodless cylinder 23 moves, driving the robotic arm 25 and the second intermediate part C attracted on the gripper 252 along the first guide rail 24 to complete the transport of the second intermediate part C over a certain distance. Then, the electromagnetic chuck at the lower end of the gripper 252 is de-energized. Under the action of the tension spring 253, the gripper 252 moves outward, releasing the attraction to the second intermediate part C. The slider of the first rodless cylinder 23 drives the robotic arm 25 back to the initial position, waiting to transport the second intermediate part C again.

[0131] like Figure 17-18 As shown, the second hydraulic press 3 includes a second bed 31, a second small hydraulic cylinder 32, a second left side mold 33, a second large hydraulic cylinder 34, a second clamping plate 35, a second right side mold 36, and a second lower mold 37; the second clamping plate 35 is T-shaped, and a rubber layer is pasted on the bottom surface of its vertical plate. The rubber layer has several protrusions to increase the coefficient of friction.

[0132] Two large hydraulic cylinders 34 are installed on the top surface of the second bed 31. Their hydraulic rods pass through the through holes on the top surface of the second bed 31, and the ends of their hydraulic rods are connected to the top surface of the second clamping plate 35.

[0133] The second lower mold 37 is installed on the workbench of the second bed 31. The cross-sectional shape of the second lower mold 37 matches the cross-sectional shape of the T-shaped elevator guide rail.

[0134] When the hydraulic rod of the No. 2 large hydraulic cylinder 34 installed on the top surface of the No. 2 bed 31 extends or retracts, it drives the No. 2 clamping plate 35 to move up and down.

[0135] Two small hydraulic cylinders 32 are installed on the left and right side plates in the middle of the second bed 31. The hydraulic rods of the small hydraulic cylinders 32 pass through the through holes in the middle side plates of the second bed 31. The ends of the hydraulic rods of the two small hydraulic cylinders 32 installed on the left side plate are connected to the second left mold 33. The ends of the hydraulic rods of the two small hydraulic cylinders 32 installed on the right side plate are connected to the second right mold 36. The cross-sections of the second left mold 33 and the second right mold 36 match the fourth intermediate part E.

[0136] The working process of hydraulic press No. 2, part 3 is as follows:

[0137] 1) When the second intermediate part C moves to the second hydraulic press 4, the hydraulic rod of the second large hydraulic cylinder 34 installed on the top surface of the second bed 31 extends, which drives the second clamping plate 35 to move down, and the second clamping plate 35 reliably presses the second intermediate part C onto the second lower mold 37.

[0138] 2) When the hydraulic rod of the second small hydraulic cylinder 32, which is installed on the left and right side plates in the middle of the second bed 31, extends, it will drive the second left mold 33 and the second right mold 36 to move towards each other, and hydraulically transform the second intermediate part C into the third transition part D.

[0139] 3) The hydraulic rod of the No. 2 large hydraulic cylinder 34 installed on the top surface of the No. 2 bed 31 retracts, causing the No. 2 clamping plate 35 to move upward. The No. 2 clamping plate 35 no longer presses the No. 2 intermediate part C onto the No. 2 lower mold 37. The hydraulic rod of the No. 2 small hydraulic cylinder 32 installed on the left and right side plates in the middle of the No. 2 bed 31 retracts, causing the No. 2 left side mold 33 and the No. 2 right side mold 36 to move away from the No. 3 transition part D. The No. 3 transition part D moves forward a certain distance.

[0140] 4) Repeat steps 1-3 until intermediate part C is completely hydraulically compressed into intermediate part E.

[0141] like Figure 19 As shown, the second conveyor 4 includes a second platform 41 and a lateral rolling assembly 42;

[0142] Two sets of lateral rolling conveyor assemblies 42 are installed on the top surface of the second platform 41, and the space constructed between the two sets of lateral rolling conveyor assemblies 42 matches the shape of the fourth intermediate part E.

[0143] like Figure 20-21 As shown, the lateral rolling assembly 42 includes a lateral mounting plate 421, a worm gear 422, a roller assembly 423, a worm shaft 424, a slave timing pulley 425, a timing belt 426, a main timing pulley 427, and a drive motor 428.

[0144] The starting end face of the lateral mounting plate 421 is machined with rounded corners to facilitate the flow of the upstream intermediate component E.

[0145] The roller assembly 423 includes a cylindrical roller, a worm gear, and a short shaft, with the cylindrical roller and worm gear mounted on the short shaft;

[0146] Several roller kits 423 are installed in a linear array in the square through holes on the inclined surface of the side mounting plate 421. The worm shaft 424 is installed on the back side of the inclined surface of the side mounting plate 421 through a bearing with a seat. Several worms 422 are fitted on the worm shaft 424. The worms 422 fitted on the worm shaft 424 mesh with the worm wheel of the roller kit 423.

[0147] The drive motor 428 is installed at one end of the vertical surface of the side mounting plate 421. A main synchronous pulley 427 is installed on the output shaft of the drive motor 428. A driven synchronous pulley 425 is fitted at one end of the worm shaft 424. The main synchronous pulley 427 installed on the output shaft of the drive motor 428 and the driven synchronous pulley 425 fitted at one end of the worm shaft 424 are connected by a synchronous belt 426.

[0148] When the output shaft of the drive motor 428 rotates, it drives the short shaft of the roller assembly 423 and the cylindrical roller to rotate together through the synchronous belt mechanism and the worm gear mechanism, thereby driving the fourth intermediate piece E placed between the two sets of lateral rolling assemblies 42 to move forward.

[0149] like Figure 22 As shown, the No. 3 hydraulic press 5 includes a No. 3 bed 51, a No. 3 small hydraulic cylinder 52, a No. 3 left module 53, a No. 3 large hydraulic cylinder 54, a No. 3 clamping plate 55, a No. 3 lower mold 56, four No. 3 guide rods 57, a No. 3 linear bearing 58, and a No. 3 right module 59.

[0150] A rubber layer is pasted on the bottom surface of the second clamping plate 35. The rubber layer has several protrusions to increase the coefficient of friction.

[0151] Two large hydraulic cylinders 54 are installed on the top surface of the No. 3 bed 51. Their hydraulic rods pass through the through holes on the top surface of the No. 3 bed 51, and the ends of their hydraulic rods are connected to the top surface of the No. 3 clamping plate 55.

[0152] When the hydraulic rod of the No. 3 large hydraulic cylinder 54 installed on the top surface of the No. 3 bed 51 extends or retracts, it drives the No. 3 clamping plate 55 to move up and down.

[0153] A small hydraulic cylinder 52 is installed at the front end of the left and right side plates in the middle of the No. 3 bed 51. A linear bearing 58 is installed on the left and right side plates in the middle of the bed 51 on both sides of the small hydraulic cylinder 52. Two guide rods 57 pass through the linear bearing 58 installed on the left side plate in the middle of the No. 3 bed 51, and their flange ends are fixed to the left module 53. The other two guide rods 57 pass through the linear bearing 58 installed on the right side plate in the middle of the No. 3 bed 51, and their flange ends are fixed to the right module 59. The hydraulic rods of the small hydraulic cylinders 52 on the left and right sides pass through the through holes in the middle side plate of the No. 3 bed 51, and their ends are fixed to the left module 53 and the right module 59. The upper inner edges of the left module 53 and the right module 59 are all machined with rounded corners.

[0154] The cross-sectional shape of the No. 3 lower mold 56 matches the cross-sectional shape of the T-shaped hollow elevator guide rail, and there is a notch at the front end. It is installed on the worktable of the No. 3 bed 51.

[0155] The working process of hydraulic press No. 3, part 5 is as follows:

[0156] 1) When the fourth intermediate part E moves to the third hydraulic press 5, the hydraulic rod of the third large hydraulic cylinder 54 installed on the top surface of the third bed 51 extends, which drives the third clamping plate 55 to move down, and the third clamping plate 55 reliably presses the fourth intermediate part E onto the third lower mold 56.

[0157] 2) When the hydraulic rod of the small hydraulic cylinder 52 installed on the middle left side plate of the third bed 51 extends, it will drive the left side mold 53 of the third bed to move closer to the middle part E of the fourth bed;

[0158] 3) When the hydraulic rod of the small hydraulic cylinder 52 installed on the middle left side plate of the third bed 51 retracts, it will drive the left mold 53 of the third bed away from the middle part E of the fourth bed;

[0159] 4) When the hydraulic rod of the No. 3 small hydraulic cylinder 52 installed on the middle right side plate of the No. 3 bed 51 extends, it will drive the No. 3 right side mold 59 to approach the No. 4 intermediate part E, and squeeze the other side of the No. 4 intermediate part E into a horizontal position. At this time, the No. 4 intermediate part E is processed into the No. 5 transition part F.

[0160] 5) When the hydraulic rod of the small hydraulic cylinder 52 installed on the middle right side plate of the No. 3 bed 51 retracts, it will drive the No. 3 right side mold 53 away from the No. 5 transition piece F;

[0161] 6) The hydraulic rod of the No. 2 large hydraulic cylinder 54 installed on the top surface of the No. 3 bed 51 retracts, which drives the No. 3 clamping plate 55 to move upward. The No. 3 clamping plate 55 no longer clamps and clamps the No. 5 transition piece F onto the No. 3 lower mold 56. The No. 5 transition piece F moves forward a certain distance.

[0162] 7) Repeat steps 1-6 until the fourth transition piece F is fully hydraulically formed into a T-shaped hollow elevator guide rail semi-finished product G.

[0163] The forming method of T-shaped hollow elevator guide rail is as follows:

[0164] 1) Conveyor 0 transports the T-shaped hollow elevator guide rail blank A to hydraulic press 1;

[0165] 2) Hydraulic press 1 first hydraulically presses the T-shaped hollow elevator guide rail blank A into the first transition part B, and then hydraulically presses it into the second intermediate part C through multiple segments.

[0166] 3) Conveyor 2 will transport intermediate part C to hydraulic press 3 in multiple steps at a certain step size;

[0167] 4) Hydraulic press 3 first hydraulically presses intermediate part C into transition part D, and then hydraulically presses it into intermediate part E in multiple segments.

[0168] 5) Conveyor 4 will transport intermediate part E to hydraulic press 5 in steps 4 times.

[0169] 6) Hydraulic press 5 first hydraulically presses intermediate part E to form transition part F, and then through multiple segmented hydraulic presses, forms T-shaped hollow elevator guide rail semi-finished product G.
