Description

Technical Field

[0001] The invention belongs to the technical field of profile processing equipment, and in particular relates to a steel lining slotting device for a plastic-steel profile. Background Art

[0002] Plastic-steel profile steel lining is a metal reinforcement material embedded in the plastic profile of plastic-steel doors and windows. It is fixed to the plastic profile by welding, screws or riveting to form a composite structure. Its main purpose is to make up for the insufficient strength of pure plastic profiles and improve the overall performance of doors and windows. Plastic-steel profile steel lining is the core supporting component of building doors and windows. The accuracy and efficiency of its grooving processing directly affect product quality and production efficiency.

[0003] The traditional grooving device for steel lining of plastic steel profile has significant defects in practical application, which are mainly reflected in the following aspects:

[0004] 1. Poor dimensional adaptability: The slotting structure of existing devices (such as tool position, clamping spacing, etc.) is mostly fixed and can only adapt to a single specification of steel lining. When processing steel linings of different sizes, manual disassembly and replacement of tools, adjustment of fixture positions, and even recalibration of equipment parameters are required. This process relies on operator experience, is time-consuming and prone to increased scrap rates due to adjustment errors, seriously restricting the flexibility and automation level of the production line.

[0005] 2. The post-grooving processing is cumbersome: Traditional grooving devices only complete the cutting operation, and a large number of burrs and rough edges often remain on the groove edges. Currently, the industry generally adopts manual grinding or mechanical deburring methods, which not only increases additional labor costs and time costs, but also complicates the production process due to the separation of processes, making it difficult to meet efficient production needs.

[0006] 3. Low functional integration: The existing equipment has a single function. Grooving and grinding need to be completed by independent equipment. The equipment occupies a large area and has high energy consumption. At the same time, positioning deviation is prone to occur when multiple devices work together, affecting processing accuracy and further reducing production efficiency. Summary of the Invention

The height of the grinding disc and the push column can also be adjusted through the coordinated action of the clamping cooperative structure and the telescopic plate, ensuring that the grinding disc is flush with the surface to be processed of the steel liner and that the push column accurately squeezes the waste.

[0027] 4. Adjustable grinding disc diameter:

[0028] The grinding disc is equipped with an adjustment structure inside, which can adjust the diameter of the grinding disc according to processing requirements, further improving the flexibility and applicability of the equipment.

[0029] 5. Efficient steel lining feed drive:

This design ensures the stable movement of the steel lining during the processing and improves the processing efficiency and accuracy.

[0048] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail with reference to the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. The technical solutions of the present invention will be described in detail below with reference to the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0049] See also Figures 1 to 13 This embodiment proposes a plastic-steel profile steel lining grooving device, which includes a body 1, a power box 6, a clamping plate 8, a driving and clamping structure, a transmission structure, a clamping coordination structure and an adjustment structure.

A driving clamping structure for driving the two splints 8 to approach each other is installed inside the body 1. , a transmission structure for driving the transmission roller 9 to rotate is installed inside the body 1, and a clamping cooperation structure is installed on the top of the splint 8, and the clamping cooperation structure is used to drive the grinding disc 4 and the slotting knife 3 to cooperate with the splint 8 to move; an adjustment structure for adjusting the diameter of the grinding disc 4 is installed inside the grinding disc 4, and a motor 43 is fixedly connected to the inside of the power box 6, and the output end of the motor 43 is fixedly connected to the active rotating shaft 7, and a telescopic support plate 48 is fixedly connected to the middle of the slide 2, and the two ends of the telescopic support plate 48 are telescopic ends, and the two ends of the telescopic support plate 48 are respectively fixedly connected to the two splints 8;

[0051] It should be noted that: during the grooving process, waste is squeezed. As the steel liner is fed, the long waste strips generated by the grooving of the steel liner are squeezed downward by the push column 5 to prevent the long waste strips from contacting the grinding disc 4, causing damage to the grinding disc 4 or affecting the operation of the grinding disc 4.

[0052] See also Figure 2 and Figure 3 The driving and clamping structure includes: an electric push rod 10, a rack 11, a first gear 12 and a bidirectional threaded rod 13. The electric push rod 10 is fixedly connected to the inside of the body 1, and the output end of the electric push rod 10 is fixedly connected to the bottom of the power box 6. The bottom of the power box 6 is fixedly connected to the rack 11. The first gear 12 is rotatably connected to the inside of the body 1. The first gear 12 is meshed with the rack 11. The inner wall of the first gear 12 is fixedly connected to the bidirectional threaded rod 13. The bidirectional threaded rod 13 is threadedly connected to the bottom of the two clamping plates 8.

[0053] It should be noted that: the drive clamping structure is used for transmission, and the symmetrically arranged clamping plates 8 are driven to move toward each other by rotating the bidirectional threaded rod 13, so as to achieve clamping and fixing of the steel liner.

[0054] See also Figures 3 to 6The transmission structure includes: a driving bevel gear 14, a driven bevel gear 15, a first telescopic transmission rod 16, a gearbox 17, a first worm 18, a first connecting rod 19, a second worm 20, a first worm wheel 21 and a second worm wheel 22; the power box 6 is internally rotatably connected to the driving bevel gear 14, the driving bevel gear 14 is fixedly connected to the outer wall of the driving shaft 7, the interior of the power box 6 is located below the driving bevel gear 14 and is rotatably connected to the driven bevel gear 15, the bottom of the driven bevel gear 15 is fixedly connected to the first telescopic transmission rod 16, the body 1 is fixedly connected to the gearbox 17, the bottom of the first telescopic transmission rod 16 is fixedly connected to the input end of the gearbox 17, and the bottoms of the two splints 8 are symmetrically rotatably connected to the first worm 1 8.

The first telescopic transmission rod 16 consists of an inner rod 46 and an outer rod 47. The inner rod 46 and the outer rod 47 are slidably connected by splines.

[0055] It should be noted that: the rotation of the output end of the motor 43 is converted into low-speed feeding of multiple sets of transmission rollers 9 through a multi-stage worm gear transmission. The design of the spline sliding connection not only ensures that the first worm 18 can move with the splint 8, but also does not affect the rotation of the first worm 18. The first connecting rod 19 is designed with a spline so that the two first worms 18 are driven to rotate by the output shaft of the gearbox 17.

[0056] See also Figure 4 、 Figures 7 to 9 The clamping cooperative structure includes: a first push block 23, a second connecting rod 24, a mounting ring 25, a second push block 26 and a third connecting rod 27.

[0057] It should be noted that: while the splint 8 clamps the steel liner, the splint 8 can simultaneously adjust the positions of the four second push blocks 26 through the first push block 23, the second connecting rod 24, the mounting ring 25, the second push block 26 and the third connecting rod 27, and the spacing and height of the two grooving knives 3 and the height of the grinding disc 4 can be adjusted by adjusting the second push block 26.

[0058] See also Figures 7 to 13 The grinding disc 4 is composed of four grinding discs 28, and a connecting piece 29 is symmetrically installed between two adjacent grinding discs 28. The two ends of each connecting piece 29 are respectively slidably connected to the two adjacent grinding discs 28; the adjustment structure includes: a third push block 30, a first rotating rod 31, an L-shaped connecting rod 32, a telescopic plate 33, a third worm 34, a second transmission rod 35, a third worm gear 36, an adjustment block 37, a connecting ring 38, an upper mounting plate 39, a connecting plate 40, a connecting block 41 and a lower mounting plate 42. The tops of the two second push blocks 26 near the grinding disc 4 are fixedly connected to the third push block 30. The top of the third push block 30 is rotatably connected to the first rotating rod 31, and the ends of the two first rotating rods 31 close to each other are rotatably connected. The ends of the two first rotating rods 31 close to each other are rotatably connected to the L-shaped connecting rod 32. The sides of the two second push blocks 26 close to the grinding disc 4 are fixedly connected to the telescopic plate 33, and the telescopic plate 33 is rotatably connected to the third worm 34 in the horizontal direction. The telescopic plate 33 is rotatably connected to the second transmission rod 35 in the longitudinal direction. The top of the second transmission rod 35 is rotatably connected to the bottom of the L-shaped connecting rod 32, and the inner part of the telescopic plate 33 is rotatably connected to the first The third worm gear 36 is meshed with the third worm gear 34, and the axis of the third worm gear 36 is slidably connected to the second transmission rod 35 through a spline. The bottom of the second transmission rod 35 is fixedly connected to an adjusting block 37, and the bottom of the telescopic plate 33 is fixedly connected to a connecting ring 38. The bottom of the connecting ring 38 is rotatably connected to an upper mounting plate 39. The adjusting block 37 is slidably connected to the axis of the upper mounting plate 39. The bottom of the side wall of the adjusting block 37 is rotatably connected to four connecting plates 40. The end of the connecting plate 40 away from the adjusting block 37 is rotatably connected to a connecting block 41. The four connecting blocks 41 are The tops are all slidably connected to the upper mounting plate 39, the bottoms of the four connecting blocks 41 are fixedly connected to the corresponding grinding discs 28, the bottoms of the four grinding discs 28 are installed with a lower mounting plate 42, the bottoms of the four grinding discs 28 are all slidably connected to the lower mounting plate 42, the outer wall of one end of the driving shaft 7 is fixedly connected to a driving pulley 44, and one end of the third worm 34 is fixedly connected to a driven pulley 45, the driving pulley 44 and the driven pulley 45 are connected by belt transmission, the grinding disc 4 is hourglass-shaped as a whole, and the horizontal diameter of the grinding disc 28 gradually decreases from one end to the other end.

[0059] It should be noted that the third worm 34 placed horizontally in the telescopic plate 33 is cross-intersected with the second transmission rod 35 placed vertically, the third worm 34 is meshed with the third worm gear 36, and the second transmission rod 35 is connected to the third worm gear 36 through a spline, constraining the telescopic plate 33 to move only in the vertical direction. The upper mounting plate 39 and the lower mounting plate 42 jointly limit the grinding sheet 28 to prevent the grinding sheet 28 from falling apart during the grinding process, thereby ensuring the stability of the grinding plate 4 structure. Figure 12 As shown, the grinding disc 28 rotates clockwise during operation, and the end with a smaller diameter of the grinding disc 28 is located in front of the end with a larger diameter in the direction of movement, so as to prevent the sharp corners of the grinding disc 28 from contacting the steel lining first during the grinding process and causing the steel lining to be scratched.

[0060] The telescopic plate 33 is composed of sliding plates at both ends and a fixed plate in the middle, and the sliding plate is slidably connected to the fixed plate; one side of the middle of the telescopic plate 33 is fixedly connected to the push post 5, and since the two ends of the push post 5 are respectively connected to the two third connecting rods 27 in a horizontal sliding manner, as the two third connecting rods 27 move toward each other, the third connecting rod 27 will slide relative to the push post 5; and because the push post 5 is fixed to the telescopic plate 33, the push post 5 will not move, and the two connecting rods 27 play a certain auxiliary role for the push post 5; since the sliding plates at both ends of the telescopic plate 33 can be retracted into the fixed plate in the middle of the telescopic plate 33, the telescopic plate 33 can be retracted. The fixed plate in the middle of the retractable plate 33 is provided with a through hole, the diameter of the through hole is the same as the diameter of the second transmission rod 35, and the telescopic plate 33 and the second transmission rod 35 are connected by a spline sliding connection. Because the telescopic plate 33 has a certain thickness, the telescopic plate 33 and the second transmission rod 35 are always kept in a vertical state. Because the connection point of the two first rotating rods 31 is located at the top of the second transmission rod 35, when the second transmission rod 35 is perpendicular to the telescopic plate 33, the position of the second transmission rod 35 will be restricted by the first rotating rod 31, which will restrict the fixed plate in the middle of the telescopic plate 33, and then further restrict the position of the push column 5.

[0061] The working principle of the steel lining slotting device for plastic steel profiles provided by the present invention is as follows:

[0062] Steel lining clamping and positioning:

[0063] The steel lining to be processed is placed horizontally in the slide 2 on the top of the machine body 1, with the axis of the steel lining in the same direction as the slide 2, and the electric push rod 10 is started. The output end of the electric push rod 10 is retracted and pulls the power box 6 to move vertically downward. The rack 11 fixed at the bottom of the power box 6 drops synchronously with the power box 6 and drives the first gear 12 engaged with it to rotate clockwise. The first gear 12 drives the coaxially fixed bidirectional threaded rod 13 to rotate synchronously. The reverse threads at both ends of the bidirectional threaded rod 13 are respectively connected to the bottom threads of the two splints 8. The bidirectional threaded rod 13 drives the two splints 8 to move symmetrically toward each other along the slide 2. During the movement of the splint 8, the multiple sets of transmission rollers 9 inside it contact the surface of the steel lining. When the spacing between the splints 8 matches the width of the steel lining, the transmission rollers 9 generate a uniform radial clamping force on the steel lining, and the electric push rod 10 stops moving to complete the fixation of the steel lining.

[0064] The spacing and height of slotting knives 3 are adjusted synchronously:

[0065] The electric push rod 10 pulls the power box 6 to move vertically downward, driving the active rotating shaft 7 fixedly connected to the motor 43 inside it to synchronously descend. The active rotating shaft 7 is connected to the mounting ring 25 through a spline, allowing the mounting ring 25 to slide axially. When the power box 6 descends, the slotting knife 3 is synchronously lowered in height with the active rotating shaft 7, and the first push block 23 on the top of the splint 8 moves toward the splint 8, pushing the second connecting rod 24 to rotate around the hinge point between it and the first push block 23. The rotating second connecting rod 24 pushes the second push block 26 to slide axially along the active rotating shaft 7. The two second push blocks 26 approach each other and drive the slotting knife 3 to move horizontally toward the central axis of the steel liner synchronously through the mounting ring 25 to adjust the slotting width. While the slotting knife 3 descends vertically driven by the power box 6, the width adjustment is achieved through the horizontal sliding of the mounting ring 25, and finally the width and height of the slotting knife 3 are matched with the size of the groove to be processed.

[0066] Height adjustment of grinding disc 4 and push column 5:

[0067] The two second push blocks 26 near the slotting knife 3 drive the two second push blocks 26 near the grinding disk 4 to approach and descend synchronously through the third connecting rod 27. The approaching action of the two second push blocks 26 near the grinding disk 4 will push the sliding plate of the telescopic plate 33 fixed thereto to retract, and the descending movement of the second push blocks 26 will drive the telescopic plate 33 to move downward. The fixed plate in the middle of the telescopic plate 33 is fixedly connected to the push column 5 to ensure that the push column 5 is always aligned with the central axis of the slide groove 2. The telescopic plate 33 drives the push column 5 and the connecting ring 38 to descend, driving the upper mounting plate 39 and the grinding disk 4 to lower their height synchronously until the middle of the grinding disk 4 is flush with the surface of the steel liner to be processed, and the bottom of the push column 5 is flush with the bottom of the lower mounting plate 42.

[0068] Grinding disc 4 diameter adjustment:

[0069] The third push block 30 descends with the second push block 26 and approaches toward each other, and the third push block 30 pushes the first rotating rod 31 to rotate around the hinge point. The two first rotating rods 31 are linked by the L-shaped connecting rod 32. The rotation of the two first rotating rods 31 drives the L-shaped connecting rod 32 to move away from the telescopic plate 33, and the L-shaped connecting rod 32 drives the second transmission rod 35 rotatably connected to its bottom to move away from the grinding disk 4. The second transmission rod 35 drives the adjusting block 37 fixedly connected to its bottom to move away from the grinding disk 4. In the process of moving away from the grinding disk 4, the adjusting block 37 pulls the connecting plate 40, and the connecting plate 40 drives the connecting block 41 rotatably connected to it to slide in the upper mounting plate 39, and drives the grinding disc 28 fixedly connected to its bottom to approach the axis of the upper mounting plate 39. In the process of the grinding discs 4 approaching each other, the connecting piece 29 slides in the grinding disc 4, thereby realizing the adjustment of the diameter of the grinding disc 4.

[0070] Steel lining feed drive:

[0071] The motor 43 in the power box 6 drives the active shaft 7 to rotate at high speed, and the active shaft 7 drives the active bevel gear 14 to rotate. The active bevel gear 14 drives the driven bevel gear 15 engaged with it to rotate, and the driven bevel gear 15 drives the first telescopic transmission rod 16 to rotate synchronously. The first telescopic transmission rod 16 transmits power to the gearbox 17, and outputs it to the first worm 18 after speed change. The first worm 18 drives the first connecting rod 19 to rotate through the spline, driving another group of first worms 18 to rotate synchronously. The two first worms 18 drive the second worm 20 to rotate through the first worm gear 21. The second worm 20 engages to drive the second worm gear 22 and the transmission roller 9 to rotate at a low speed, and the steel lining is fed along the slide 2 under the action of friction.

[0072] Integrated processing of slotting and grinding:

[0073] The steel liner moves with the transmission roller 9 to the bottom of the slotting knife 3. The high-speed rotating slotting knife 3 has been lowered to the set height and adjusted to the set width to mill and slot the steel liner. As the steel liner is fed, the long waste strips generated by the slotting of the steel liner gradually approach the push column 5. The bottom of the push column 5 is designed to be arc-shaped on the side close to the waste. After the waste contacts the push column 5, it is squeezed by the push column 5. Because the position of the push column 5 is fixed, the waste is squeezed downward by the push column 5 to prevent the long waste strips from affecting the work of the grinding disk 4. The slotted steel liner enters the grinding disk 4 area, and the rotating grinding disc 28 grinds the edge of the slot to eliminate burrs.

[0074] Reset after processing is completed:

[0075] After the processing is completed, the piston rod of the electric push rod 10 retracts, driving the power box 6 to rise and reset, the rack 11 drives the first gear 12 to rotate counterclockwise, the bidirectional threaded rod 13 separates the splint 8, the transmission roller 9 stops rotating, the steel lining is manually removed, and the device returns to its initial state to prepare for the next cycle.
