Description

Technical Field

[0001] This invention relates to the field of sheet metal shearing technology, specifically to a rotary compensator-based shearing equipment. Background Technology

[0002] Rotary compensators are core adaptable components in pipeline thermal compensation systems. They mainly consist of a bellows body, a rotary sealing structure, a limiting connection structure, and end connection flanges. With their advantages of rotation, bidirectional axial and radial compensation, high pressure resistance, and high sealing stability, they are widely used in pipeline systems such as thermal pipelines, chemical pipelines, and power grids that require compensation for thermal expansion and contraction deformation and buffering of installation deviations and vibration displacement. The bellows body, as the core deformation and sealing component of the rotary compensator, directly determines the overall sealing performance, deformation compensation accuracy, and service life of the compensator through its processing quality. The bellows body is mainly formed from stainless steel sheets and strips of different specifications through processes such as fixed-length shearing, rolling, welding, and shaping. Therefore, the shearing process of stainless steel sheets is the first critical step in the production of rotary compensators. Currently, the industry generally uses traditional mechanical or hydraulic shearing equipment to complete the shearing operation for compensator sheets.

[0003] However, the existing conventional shearing equipment has inherent defects in its shearing structure design. Traditional shearing machines mostly use a unidirectional, single-cutting structure. The overall working logic is that after a single downward cut to complete the shearing of the sheet metal, the cutter must completely move upward to reset, disengage from the shearing station, and make room for the sheet metal feeding gap before it can push the sheet metal to move a fixed distance again. Then the cutter moves downward again to perform the next shearing operation. The entire machine can only complete a single sheet metal shearing operation to complete one complete reciprocating lifting motion. This unidirectional shearing operation mode results in a low percentage of effective operation per work cycle and an increased percentage of ineffective working time spent waiting for sheet metal feeding and idling for the cutter to reset. Especially when adapting to the batch continuous thin sheet metal blanking processing scenario of rotary compensators, the frequent reset waiting process will reduce the overall blanking processing efficiency and cannot match the large-scale, assembly line production rhythm of rotary compensators. Summary of the Invention

Compared with existing shearing machines that require one reciprocating motion to complete the shearing, the shearing efficiency is much higher.

[0015] 2.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 12 As shown, the present invention includes the following embodiments: Example 1: A rotary compensator processing shearing equipment includes a frame 1 and a feed chute 11 extending through the frame 1 from front to back; slide rods 2 are vertically fixed to the left and right inner walls of the frame 1; two slide rods 2 pass through L-shaped seats 3 vertically; a tool holder 4 is fixedly connected between the two L-shaped seats 3; a cutter 5 is fixedly connected to the front side of the tool holder 4; the cutter 5 and the left and right ends of the tool holder 4 are at different heights; a connecting rod 6 is rotatably connected to the lower side of the two L-shaped seats 3; a crank 61 is rotatably connected to the lower end of the connecting rod 6; the two cranks 61 are fixedly connected by a handle 62; the handle 62 is rotatably connected to the frame 1, and one of the cranks 61 is driven by a main motor 63; the main motor 63 drives the connecting rod 6 and the L-shaped seat 3 to move through the crank 61; the cutting... The blade 5 reciprocates up and down and passes over the feed chute 11; a pressure plate 7 is provided above the shearing table 12 located on the front side of the frame 1; a pull hole 71 is provided on the upper surface of the pressure plate 7; the lower end of a T-shaped rod 72 is slidably connected in the pull hole 71; the upper end of the T-shaped rod 72 is fixedly connected to the frame 1; the upper end of the T-shaped rod 72 is connected to the upper end of the pressure plate 7 by a tension spring 73; a notch 13 is provided on the rear edge of the shearing table 12 near the end position; a U-shaped seat 74 is slidably connected to the shearing table 12 near the notch 13; the U-shaped seat 74 is pressed forward by the extrusion block 31 on the L-shaped seat 3; a right-angled trapezoidal groove 75 is provided on the side of the U-shaped seat 7 facing the pressure plate 7; the inclined surface of the right-angled trapezoidal groove 75 is in contact with the driven rod 76; the driven rod 76 is connected to the pressure plate 7.

[0022] When processing the rotary compensator, stainless steel strips or thin plates (hereinafter collectively referred to as plates) need to be cut to a fixed length. The cut plates are used to roll the bellows body of the compensator. After the plates are placed on the shearing table 12 at the front of the frame 1, the plates are controlled to move backward. The plates will pass through the gap between the lower surface of the pressure plate 7 and the upper surface of the shearing table 12. The plates will then pass through the feed chute 11 and pass over the cutter 5. The cutter 5, the pressure plate 7 and the shearing table 12 form a clamping gap that is staggered, so the plates can move backward smoothly. After the sheet material moves backward a certain distance, the main motor 63 drives the output end to rotate. The main motor 63 drives the handle 62 to rotate, and the handle 62 drives the crank 61 to rotate. The structure of the two cranks 61 is two discs and an eccentric shaft fixedly connected between the two discs. As the cranks 61 rotate, they drive the connecting rod 6 to pull and push the L-shaped seat 3 up and down. During the downward movement of the L-shaped seat 3, it drives the connected extrusion block 31 to move downward. The opening of the U-shaped seat 74 faces forward, and the rear side is set into an isosceles trapezoidal structure. Thus, during the process of the extrusion block 31 extruding the rear side of the U-shaped seat 74, the U-shaped seat 74 moves forward along the shearing table 12. During the forward movement of the U-shaped seat 74, it drives the inclined surface inside the right-angled trapezoidal groove 75 to extrude the driven rod 76. Thus, the driven rod 76 is guided downward by the inclined surface inside the right-angled trapezoidal groove 75. As the moving rod 76 moves downward, it pulls the pressure plate 7 downward. As the pressure plate 7 moves downward, it causes the pull hole 71 and the pull rod to move and pull the tension spring 73. The pressure plate 7 will press the plate tightly in the pressing gap between the pressure plate 7 and the shearing table 12. As the extrusion block 31 moves in the plane position of the isosceles trapezoidal structure behind the U-shaped seat 74, the plate is continuously pressed. As the L-shaped seat 3 continues to move downward, the L-shaped seat 3 will drive the knife holder 4 and the cutter 5 to move downward. The cutter 5 is tilted because the left and right heights are inconsistent. Therefore, the lower edge of the cutter 5 can cut the pressed plate during the downward movement. The cut plate will slide down the slope at the lower position of the rear side of the frame 1. After the cutter 5 crosses the pressing gap, the extrusion block 31 will also move away from the rear plane of the U-shaped seat 74, releasing the forward pressing on the U-shaped seat 74. Subsequently, the tension spring 73 pulls the pressure plate 7 upward. During this upward movement, the pressure plate 7 disengages from the sheet material, releasing the pressure. The upward movement of the pressure plate 7 also drives the driven rod 76 upward, which in turn compresses the inclined surface of the right-angled trapezoidal groove 75, causing the U-shaped seat 74 to move backward along the shearing table 12. The sheet material then moves backward a short distance, and the main motor 63 again controls the L-shaped seat 3 to move upward. The L-shaped seat 3 then drives the pressing block 31 to press the rear end of the U-shaped seat 74. The isosceles trapezoidal inclined plane guides the material into the plane position. The pressure plate 7 will press the material onto the upper surface of the shearing table 12 again. Then the cutter 5 will pass through the pressing gap. As the upper edge of the cutter 5 moves upward, it will cut the pressed material. The cut material will fall to the slope at the lower rear side of the frame 1. As the L-shaped seat 3 moves upward, the extrusion block 31 will move from the plane position at the rear end of the U-shaped seat 74 to the inclined position. The material is released from the pressure and moves backward again. This process is repeated to achieve back-and-forth shearing.

[0023] In this embodiment, the L-shaped seat 3 drives the cutter 5 to move back and forth across the clamping gap in conjunction with the pressure plate 7 to clamp the board, thereby allowing the board to be sheared by the cutter 5 moving up and down. Compared with existing shearing machines that require one reciprocating motion to complete the shearing, the shearing efficiency is higher.

[0024] Example 2: Two L-shaped seats 3 are provided with adjustment grooves 32 on opposite sides; adjustment blocks 33 are slidably connected in the adjustment grooves 32; adjustment blocks 33 are fixedly connected to pressing blocks 31; adjustment grooves 32 are threaded through and connected to adjustment bolts 34 with handles; adjustment bolts 34 are rotatably connected to adjustment blocks 33.

[0025] In this embodiment, the adjusting block 33 is fixedly connected to the extrusion rod 35; the extrusion block 31 is rotatably connected to the extrusion rod 35; the extrusion block 31 is shaped like a circular sleeve; and the driven rod 76 is rotatably connected to the pressure plate 7.

[0026] Before shearing the sheet metal, two adjusting bolts 34 are simultaneously turned. Turning the adjusting bolts 34 causes the adjusting block 33 to rotate. Under the influence of the adjusting bolts 34, the adjusting block 33 moves forward and backward along the adjusting groove 32. As the adjusting block 33 moves forward, the pressing block 31 is moved relatively forward, thus extending the pressing distance of the U-shaped seat 74 further forward. This causes the driven rod 76 to be pressed further downward by the inclined surface within the right-angled trapezoidal groove 75. Consequently, the distance between the pressure plate 7 and the shearing table 12 is reduced, allowing for tighter pressing of thinner sheet metal. The lower surface of plate 7 is fixedly connected to the pressure strip by a buffer pad. The buffer pad is made of rubber material. On the one hand, it can buffer the plate during the pressing process, and on the other hand, it can compensate for the error of the front and back position of the adjusting bolt 34 adjusting the adjusting block 33. Plates with slight thickness deviations can also be pressed. After the pressing block 31 moves backward with the adjusting block 33, the forward movement distance of the U-shaped seat 74 under the pressure becomes smaller, which makes the downward movement distance of the driven rod 76 under the pressure of the inclined surface in the right-angled trapezoidal groove 75 less. This allows the pressure plate 7 to press thicker plates, making it suitable for shearing different plates and with a wider range of applications. In addition, the extrusion block 31 is formed into a circular sleeve and is rotatably connected to the outside of the extrusion rod 35, thereby reducing the friction between the extrusion block 31 and the rear side of the U-shaped seat 74, making the extrusion block 31 extrude the U-shaped seat 74 more smoothly; the driven rod 76 is rotatably connected to the pressure plate 7, which also reduces the friction between the driven rod 76 and the inclined surface of the right-angled trapezoidal groove 75.

[0027] Example 3: A reinforcing roller 8 is rotatably connected between the two L-shaped seats 3; the reinforcing roller 8 is located behind the cutter holder 4; a reinforcing plate 81 is fixedly connected to the reinforcing roller 8 along the tangential direction; the reinforcing plate 81 can rotate with the reinforcing roller 8 and contact the upper and lower surfaces of the cutter 5; a drive groove 36 is provided inside the L-shaped seat 3; a worm gear 361 fixedly connected to the reinforcing roller 8 is rotatably connected in the drive groove 36; the worm gear 361 (simplified in the figure) is meshed and driven by a worm 362 (simplified in the figure); the worm 362 is driven by an auxiliary motor 363.

[0028] After the L-shaped seat 3 moves the blade holder 4 and the cutter 5 to their extreme positions, the auxiliary motor 363 drives the worm gear 362 to rotate. During the rotation of the worm gear 362, the worm wheel 361 rotates, which in turn drives the reinforcing roller 8. The reinforcing roller 8 then rotates, causing the reinforcing plate 81 to flip upwards. The reinforcing plate 81 flips to the upper surface of the cutter 5 and contacts it. Then, during the shearing process of the blade holder 4 and the cutter 5, the reinforcing plate 81 provides support to the upper surface of the cutter 5, thus increasing its strength. Similarly, after the L-shaped seat 3 moves the blade holder 4 and the cutter 5 to their extreme positions, the auxiliary motor 363 drives the worm gear 362 to rotate. When the worm gear 362 rotates in the opposite direction, it drives the worm wheel 361 to rotate. The rotation of the worm wheel 361 drives the reinforcing roller 8 to rotate in the opposite direction. The reinforcing roller 8 drives the reinforcing plate 81 to flip downwards. The reinforcing plate 81 flips to the lower surface of the cutter 5 and contacts the lower surface of the cutter 5. In this way, the cutter 5 can be supported by the reinforcing plate 81 during the upward shearing process, which improves the strength of the cutter 5 in shearing the plate, thereby improving the operating stability of the shearing equipment. In addition, the meshing of the worm wheel 361 and the worm gear 362 also has a self-locking effect, which prevents the worm wheel 361 from driving the worm gear 362 to rotate, while the worm gear 362 can drive the worm wheel 361 to rotate, thus improving the stability of the reinforcing plate 81.

[0029] Example 4: Two L-shaped seats 3 are provided with locking grooves 37 on their adjacent sides; the two locking grooves 37 in the same L-shaped seat 3 are located above and below the tool holder 4 respectively; a locking bar 371 is movably connected in the locking groove 37; the locking bar 371 is connected to the bottom of the locking groove 37 through a miniature telescopic rod 372; after the reinforcing plate 81 is flipped upward, the locking bar 371 can move above the reinforcing plate 81, and after the reinforcing plate 81 is flipped downward, the locking bar 371 can move below the reinforcing plate 81.

[0030] In this embodiment, the length of the locking bar 371 is adapted to the width of the reinforcing plate 81.

[0031] After the reinforcing plate 81 flips upwards and supports the upper surface of the cutter 5, the miniature telescopic rod 372 above the cutter holder 4 is activated. The miniature telescopic rod 372 can be a miniature electric push rod, an electromagnet, or one of these. During its extension, the miniature telescopic rod 372 above the cutter holder 4 causes the locking bar 371 to extend out of the locking groove 37. The locking bar 371 above the cutter holder 4 then moves to the upper surface of the reinforcing plate 81, thus limiting and locking the upper surface of the reinforcing plate 81. This increases the strength of the reinforcing plate 81 while preventing it from flipping over. In addition, the locking bar 37... The length of 1 further enhances the limiting effect on the reinforcing plate 81; when the reinforcing plate 81 needs to be flipped downwards, simply control the miniature telescopic rod 372 above the blade holder 4 to shorten and move the locking bar 371 away from the reinforcing plate 81. The locking bar 371 returns to the locking groove 37. Then, control the reinforcing plate 81 to flip downwards and contact and support the lower surface of the cutter 5. At this time, control the miniature telescopic rod 372 below the blade holder 4 to move the locking bar 371 out of the locking groove 37. The locking bar 371 moves to the lower surface of the reinforcing plate 81, thereby locking the reinforcing plate 81 and preventing the reinforcing plate 81 from flipping upwards.

[0032] Example 5: The cutter 5 has a stepped hole 51 extending through it from front to back; an internal hexagon bolt 52 passes through the stepped hole 51; the end of the internal hexagon bolt 52 is threadedly connected to the cutter holder 4.

[0033] It should be noted that the cutter 5 can be replaced periodically by loosening the internal hex bolt 52.

[0034] Example 6: The upper surface of the tool holder 4 is provided with an upper block 41; the tool holder 4 is provided with a lower block 42; the upper block 41 is located at a lower position on the upper surface of the tool holder 4; the lower block 42 is located at a higher position on the lower surface of the tool holder 4.

[0035] In this embodiment, the tool holder 4 has a central groove 43 inside; a central gear 45 is rotatably connected to the central groove 43 via a torsion spring 44; the upper surface of the tool holder 4 has an upper groove 46 corresponding to the upper block 41; the upper block 41 is slidably connected to the upper groove 46; the lower surface of the tool holder 4 has a lower groove 47 corresponding to the lower block 42; the lower block 42 is slidably connected to the lower groove 47; the upper groove 46, the central groove 43, and the lower groove 47 are all connected; the upper block 41 and the lower block 42 are driven by meshing with the central gear 45 through teeth.

[0036] As the blade holder 4 moves the cutter 5 upwards, the upper edge of the cutter 5 shears the sheet metal. The upper block 41 is retracted into the upper groove 46 to avoid interference with the sheet metal during the shearing process, ensuring smooth shearing of the sheet metal by the upper edge of the cutter 5. Subsequently, the reinforcing plate 81 is flipped upwards, disengaging from the blade holder 4 and the lower surface of the cutter 5. The reinforcing plate 81 releases pressure on the lower block 42, and the torsion spring 44 drives the intermediate gear 45 to rotate. The intermediate gear 45 then drives the meshing upper block 41 and lower block 42 to move. The lower block 42 slides downwards along the lower groove 47, and the upper block 41 slides downwards along the upper groove 46. As the upper block 41 slides out, it pushes the plate that was just cut above the cutter 5. The upper block 41 is positioned close to the cutter 5, and the position of the upper block 41 pushing the plate closer to the cutter 5 is higher than the position away from the cutter 5. This causes the plate to slide off the upper surface of the blade holder 4 and finally fall to the outside of the shearing equipment. After the reinforcing plate 81 flips upward, the reinforcing plate 81 will squeeze the upper block 41. The upper block 41 will move along the upper groove 46 under pressure. The upper block 41 will drive the middle gear 45 to rotate against the torsion spring 44, so that the lower block 42 will also retract into the lower groove 47. This makes the lower surface of the blade holder 4 flat again and prevents the lower block 42 from protruding and interfering with the shearing of the plate by the cutter 5. As the cutter 5 moves down to cut the sheet metal, the reinforcing plate 81 flips downwards, releasing the pressure on the upper block 41. The torsion spring 44 drives the middle gear 45 to rotate, causing the middle gear 45 to drive the upper block 41 to extend out of the upper groove 46 and the lower block 42 to extend out of the lower groove 47. After the lower block 42 extends, it pushes the sheet metal that was just cut down downwards, allowing the sheet metal to fall down and be moved out quickly. Since the upper block 41 and the lower block 42 are close to the position where the sheet metal was last cut, the sheet metal can be pushed away in time. In this embodiment, by pushing away the upper block 41 and the lower block 42 in time after the sheet metal is cut, the output efficiency is improved. In addition, it can also avoid the sheet metal piling up and affecting the flipping of the reinforcing plate 81 in preparation for the conveying of the sheet metal to be cut, making the sheet metal cutting process more stable.
