Description

Technical Field

[0001] The invention belongs to the technical field of profile processing equipment, and particularly relates to a grooving device for steel liners of plastic-steel profiles. Background Art

[0002] The steel liner of plastic-steel profiles is a metal reinforcement material embedded inside the plastic profiles of plastic-steel doors and windows. It is fixed to the plastic profiles by means of welding, screws or riveting to form a composite structure. Its main purpose is to make up for the defect of insufficient strength of pure plastic profiles and improve the overall performance of the doors and windows. As the core support component of building doors and windows, the precision and efficiency of the grooving process of the steel liner of plastic-steel profiles directly affect the product quality and production efficiency.

[0003] Traditional grooving devices for steel liners of plastic-steel profiles have significant defects in practical applications, which are mainly reflected in the following aspects: 1. Poor dimensional adaptability: The grooving structures of existing devices (such as tool positions, clamping distances, etc.) are mostly fixed designs, and can only adapt to steel liners of a single specification. When steel liners of different sizes need to be processed, it is necessary to manually disassemble and replace tools, adjust the fixture positions, and even re-calibrate the equipment parameters. This process depends on the experience of operators, is time-consuming and prone to an increase in the scrap rate due to adjustment errors, seriously restricting the flexibility and automation level of the production line.

[0004] 2. Complicated post-grooving treatment process: Traditional grooving devices only complete the cutting operation, and there are often a large number of burrs and rough edges remaining on the grooved edges. At present, the industry generally uses manual grinding or mechanical deburring methods for treatment, which not only increases the additional labor cost and time cost, but also complicates the production process due to the separation of processes, and it is difficult to meet the requirements of high-efficiency production.

[0005] 3. Low functional integration: Existing equipment has a single function, and grooving and grinding need to be completed by independent equipment. The equipment occupies a large area and consumes a high amount of energy. At the same time, it is easy to have positioning deviations during the collaborative operation of multiple devices, affecting the processing precision and further reducing the production efficiency.

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail in combination with embodiments and drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solutions of the present invention will be described in detail below in combination with embodiments and drawings, but the protection scope is not limited by this.

[0025] See Figures 1 to 13 , this embodiment proposes a steel lining grooving device for plastic-steel profiles, including a machine body 1, a power box 6, a clamping plate 8, a driving and clamping structure, a transmission structure, a clamping cooperation structure and an adjusting structure.

[0026] On one side of the top of the machine body 1, a sliding groove 2 is provided. Above one end of the sliding groove 2, grooving knives 3 are symmetrically arranged. Above the other end of the sliding groove 2, a grinding disc 4 is provided. Above the sliding groove 2, between the grinding disc 4 and the grooving knives 3, a push column 5 is provided. The top of the machine body 1 is slidably connected with a power box 6. One end of the power box 6 is rotatably connected with a driving rotating shaft 7. The grooving knife 3 is slidably connected with the driving rotating shaft 7 through a spline. Inside the sliding groove 2, two clamping plates 8 are symmetrically and slidably connected. On the inner wall of the clamping plate 8, multiple groups of transmission rollers 9 are rotatably connected at equal intervals. Inside the machine body 1, a driving clamping structure for driving the two clamping plates 8 to approach each other is installed. Inside the machine body 1, a transmission structure for driving the transmission rollers 9 to rotate is installed. On the top of the clamping plate 8, a clamping cooperation structure is installed. The clamping cooperation structure is used to drive the grinding disc 4 and the grooving knives 3 to cooperate with the movement of the clamping plate 8; Inside the grinding disc 4, an adjusting structure for adjusting the diameter of the grinding disc 4 is installed. Inside the power box 6, a motor 43 is fixedly connected. The output end of the motor 43 is fixedly connected with the driving rotating shaft 7. In the middle of the sliding groove 2, a telescopic support plate 48 is fixedly connected. The two ends of the telescopic support plate 48 are telescopic ends. The two ends of the telescopic support plate 48 are respectively fixedly connected with the two clamping plates 8; It should be noted that during the grooving process, the waste is extruded. As the steel lining is fed, the long waste generated by the grooving of the steel lining is pushed downward by the push column 5, preventing the long waste from contacting the grinding disc 4 and causing damage to the grinding disc 4 or affecting the operation of the grinding disc 4.

[0027] Please refer to Figure 2 and Figure 3 As shown in FIGS. 9, the driving clamping structure includes: an electric push rod 10, a rack 11, a first gear 12, and a bidirectional threaded rod 13. Inside the machine body 1, the electric push rod 10 is fixedly connected. The output end of the electric push rod 10 is fixedly connected with the bottom of the power box 6. The bottom of the power box 6 is fixedly connected with the rack 11. Inside the machine body 1, the first gear 12 is rotatably connected. The first gear 12 is meshed with the rack 11. The inner wall of the first gear 12 is fixedly connected with the bidirectional threaded rod 13. The bidirectional threaded rod 13 is threadedly connected with the bottoms of the two clamping plates 8; It should be noted that the driving clamping structure is used for transmission. By rotating the bidirectional threaded rod 13, the symmetrically arranged clamping plates 8 are driven to move towards each other, realizing the clamping and fixing of the steel lining.

[0028] Please refer to Figures 3 to 6, the 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 gear 21 and a second worm gear 22; a driving bevel gear 14 is rotatably connected inside the power box 6, the driving bevel gear 14 is fixedly connected to the outer wall of the driving rotating shaft 7, a driven bevel gear 15 is rotatably connected below the driving bevel gear 14 inside the power box 6, the bottom of the driven bevel gear 15 is fixedly connected with a first telescopic transmission rod 16, a gearbox 17 is fixedly connected inside the machine body 1, the bottom of the first telescopic transmission rod 16 is fixedly connected to the input end of the gearbox 17, the bottoms of the two clamping plates 8 are symmetrically rotatably connected with a first worm 18, a first connecting rod 19 is provided at the bottom of one side where the two clamping plates 8 are close to each other, both of the two first worms 18 are slidably connected to the inner wall of the first connecting rod 19 through splines, the output end of the gearbox 17 is slidably connected to the first worm 18 close to the gearbox 17 through splines, the bottoms of the clamping plates 8 are both rotatably connected with a second worm 20, a first worm gear 21 is fixedly connected to the outer wall of each second worm 20, the first worm gear 21 is meshed with the first worm 18, the bottoms of multiple groups of transmission rollers 9 are all fixedly connected with a second worm gear 22, and multiple groups of the second worm gears 22 are all meshed with the second worm 20. The first telescopic transmission rod 16 is composed of an inner rod 46 and an outer rod 47, and the inner rod 46 and the outer rod 47 are slidably connected through splines; It should be noted that: the rotation of the output end of the motor 43 is converted into the low-speed feeding of multiple groups of transmission rollers 9 through multi-stage worm and worm gear transmission. The design of the spline sliding connection can not only ensure that the first worm 18 can move along with the clamping plate 8, but also does not affect the rotation of the first worm 18. The design of the spline of the first connecting rod 19 enables both of the two first worms 18 to be driven to rotate by the output shaft of the gearbox 17.

[0029] Please refer to Figure 4 , Figures 7 to 9 , the clamping cooperation 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. Two first push blocks 23 are symmetrically and fixedly connected to the tops of the two clamping plates 8, and the tops of the four first push blocks 23 are all rotatably connected with a second connecting rod 24; the top of the second connecting rod 24 is rotatably connected with a second push block 26; mounting rings 25 are fixedly connected to the sides where the two grooving knives 3 are far away from each other, the mounting rings 25 are slidably connected to the driving rotating shaft 7 through splines, and the sides where the two mounting rings 25 are far away from each other are respectively rotatably connected with the corresponding two second push blocks 26; a third connecting rod 27 is fixedly connected between the two second push blocks 26 on the same side of the chute 2, and the two ends of the push post 5 are horizontally slidably connected to the two third connecting rods 27 respectively.

[0030] It should be noted that: while the clamping plate 8 clamps the steel lining, the clamping plate 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 adjust the spacing and height of the two grooving knives 3 and the height of the grinding disc 4 by adjusting the second push block 26.

[0031] Please refer to Figures 7 to 13 , the grinding disc 4 is composed of four grinding sheets 28, and connecting sheets 29 are symmetrically installed between two adjacent grinding sheets 28. Both ends of each connecting sheet 29 are slidably connected to the two adjacent grinding sheets 28; the adjusting 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 adjusting block 37, a connecting ring 38, an upper mounting disc 39, a connecting plate 40, a connecting block 41 and a lower mounting disc 42. Third push blocks 30 are fixedly connected to the tops of the two second push blocks 26 close to the grinding disc 4. First rotating rods 31 are rotatably connected to the tops of the third push blocks 30. One ends of the two first rotating rods 31 close to each other are rotatably connected. An L-shaped connecting rod 32 is rotatably connected to one ends of the two first rotating rods 31 close to each other. Telescopic plates 33 are fixedly connected to one sides of the two second push blocks 26 close to the grinding disc 4. A third worm 34 is horizontally rotatably connected to the telescopic plate 33. A second transmission rod 35 is longitudinally rotatably connected to the telescopic plate 33. The top of the second transmission rod 35 is rotatably connected to the bottom of the L-shaped connecting rod 32. A third worm gear 36 is rotatably connected to the inside of the telescopic plate 33. The third worm gear 36 is meshed with the third worm 34. The axis of the third worm gear 36 and the second transmission rod 35 are slidably connected through a spline. The bottom of the second transmission rod 35 is fixedly connected to an adjusting block 37. A connecting ring 38 is fixedly connected to the bottom of the telescopic plate 33. The bottom of the connecting ring 38 is rotatably connected to an upper mounting disc 39. The adjusting block 37 and the axis of the upper mounting disc 39 are slidably connected. Four connecting plates 40 are rotatably connected to the bottom of the side wall of the adjusting block 37. One ends of the connecting plates 40 away from the adjusting block 37 are rotatably connected to connecting blocks 41. The tops of the four connecting blocks 41 are slidably connected to the upper mounting disc 39. The bottoms of the four connecting blocks 41 are fixedly connected to the corresponding grinding sheets 28. A lower mounting disc 42 is installed at the bottom of the four grinding sheets 28. The bottoms of the four grinding sheets 28 are slidably connected to the lower mounting disc 42. One end of the outer wall of the driving rotating shaft 7 is fixedly connected to a driving pulley 44. 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 a belt. The grinding disc 4 is overall in an hourglass shape, and the diameter of the grinding sheet 28 in the horizontal direction gradually decreases from one end to the other end.

[0032] It should be noted that: The third worm 34 horizontally placed inside the telescopic plate 33 and the second transmission rod 35 vertically placed are cross-shaped. The third worm 34 meshes with the third worm gear 36. The second transmission rod 35 is connected to the third worm gear 36 through a spline, restricting the telescopic plate 33 to move only in the vertical direction. The upper mounting plate 39 and the lower mounting plate 42 together play a limiting role on the grinding disc 28, preventing the grinding disc 28 from falling apart during grinding and ensuring the stability of the structure of the grinding disc 4, as Figure 12 shown. The grinding disc 28 rotates clockwise during operation. The smaller-diameter end of the grinding disc 28 is in front of the moving direction of the larger-diameter end, preventing the edges of the grinding disc 28 from coming into contact with the steel lining first during grinding and causing scratches on the steel lining.

[0033] The telescopic plate 33 is composed of sliding plates at both ends and a fixed plate in the middle. The sliding plates are slidably connected to the fixed plate; one side of the middle of the telescopic plate 33 is fixedly connected to the push column 5. Since the two ends of the push column 5 are horizontally slidably connected to the two third connecting rods 27 respectively, as the two third connecting rods 27 move towards each other, the third connecting rods 27 will slide relative to the push column 5; and because the push column 5 is fixed to the telescopic plate 33, the push column 5 will not move, and the two connecting rods 27 play a certain auxiliary role on the push column 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 fixed plate in the middle of the telescopic 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 slidably connected through a spline. Because the telescopic plate 33 has a certain thickness, the telescopic plate 33 and the second transmission rod 35 always remain perpendicular to each other. Also, because the connection point of the two first rotating rods 31 is located at the top of the second transmission rod 35, under the condition that 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, restricting the fixed plate in the middle of the telescopic plate 33, and then further restricting the position of the push column 5.

[0034] The working principle of the steel lining grooving device for plastic-steel profiles provided by the present invention is as follows: Steel lining clamping and positioning: Place the steel lining to be processed horizontally in the chute 2 at the top of the machine body 1, with the axis of the steel lining consistent with the direction of the chute 2. Start the electric push rod 10. The output end of the electric push rod 10 retracts and pulls the power box 6 to move vertically downward. The rack 11 fixed to the bottom of the power box 6 synchronously descends with the power box 6 and drives the first gear 12 meshed with it to rotate clockwise. The first gear 12 drives the coaxial fixed bidirectional threaded rod 13 to rotate synchronously. The reverse threads at both ends of the bidirectional threaded rod 13 are respectively threadedly connected to the bottoms of the two clamping plates 8. The bidirectional threaded rod 13 drives the two clamping plates 8 to move symmetrically and towards each other along the chute 2. During the movement of the clamping plates 8, multiple groups of transmission rollers 9 inside them come into contact with the surface of the steel lining. When the distance between the clamping plates 8 matches the width of the steel lining, the transmission rollers 9 generate a uniform radial clamping force on the steel lining. The electric push rod 10 stops operating, completing the fixation of the steel lining.

[0035] Synchronous adjustment of the spacing and height of the grooving tool 3: The electric push rod 10 pulls the power box 6 to move vertically downward, driving the driving shaft 7 fixedly connected to the motor 43 inside it to descend synchronously. The driving 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 grooving tool 3 synchronously reduces its height with the driving shaft 7. The first push block 23 at the top of the clamping plate 8 moves towards each other with the clamping plate 8, pushing the second connecting rod 24 to rotate around its hinge point with the first push block 23. The rotating second connecting rod 24 pushes the second push block 26 to slide axially along the driving shaft 7. The two second push blocks 26 approach each other, driving the grooving tool 3 to move horizontally towards the central axis of the steel lining through the mounting ring 25 to adjust the grooving width. While the grooving tool 3 vertically descends driven by the power box 6, the width adjustment is achieved through the horizontal sliding of the mounting ring 25, finally making the width and height of the grooving tool 3 both match the dimensions of the groove to be processed.

[0036] Height adjustment of the grinding disc 4 and the push post 5: The two second push blocks 26 close to the grooving tool 3 drive the two second push blocks 26 close to the grinding disc 4 to approach and descend synchronously through the third connecting rod 27. The approaching action of the two second push blocks 26 close to the grinding disc 4 will push the sliding plate of the telescopic plate 33 fixed to it to contract, and the descending movement of the second push block 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 post 5, ensuring that the push post 5 always aligns with the central axis of the chute 2. The telescopic plate 33 drives the push post 5 and the connecting ring 38 to descend, driving the upper mounting disc 39 and the grinding disc 4 to synchronously reduce their heights until the middle of the grinding disc 4 is flush with the surface of the steel lining to be processed, and the bottom of the push post 5 is flush with the bottom of the lower mounting disc 42.

[0037] Diameter adjustment of the grinding disc 4: The third pushing block 30 descends along with the second pushing block 26 and approaches each other. The third pushing block 30 drives the first rotating rod 31 to rotate around the hinge point. The two first rotating rods 31 are linked by an 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. The L-shaped connecting rod 32 drives the second transmission rod 35 rotatably connected to its bottom to move away from the grinding disc 4. The second transmission rod 35 drives the adjusting block 37 fixedly connected to its bottom to move away from the grinding disc 4. During the process of the adjusting block 37 moving away from the grinding disc 4, it pulls the connecting plate 40. The connecting plate 40 drives the connecting block 41 rotatably connected to it to slide within the upper mounting disc 39, and drives the grinding sheet 28 fixedly connected to its bottom to approach the axis of the upper mounting disc 39. During the process of the grinding discs 4 approaching each other, the connecting piece 29 slides within the grinding discs 4, realizing the adjustment of the diameter of the grinding discs 4.

[0038] Steel lining feeding drive: The motor 43 in the power box 6 drives the driving rotating shaft 7 to rotate at a high speed. The driving rotating shaft 7 drives the driving bevel gear 14 to rotate. The driving bevel gear 14 drives the driven bevel gear 15 meshing with it to rotate. The driven bevel gear 15 drives the first telescopic transmission rod 16 to rotate synchronously. The first telescopic transmission rod 16 transmits the power to the gearbox 17. After speed change, the power is output to the first worm 18. The first worm 18 drives the first connecting rod 19 to rotate through a 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 wheel 21. The second worm 20 meshes and drives the second worm wheel 22 and the transmission roller 9 to rotate at a low speed. The steel lining moves along the chute 2 under the action of friction.

[0039] Integrated grooving and grinding processing: The steel lining moves along with the transmission roller 9 to the lower part of the grooving cutter 3. The grooving cutter 3 rotating at a high speed has descended to the set height and is adjusted to the set width, milling and grooving the steel lining. As the steel lining is fed, the long waste produced by the grooving of the steel lining gradually approaches the push column 5. One side of the bottom of the push column 5 close to the waste is arc-shaped. 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, preventing the long waste from affecting the work of the grinding disc 4. The grooved steel lining enters the area of the grinding disc 4, and the rotating grinding sheet 28 grinds the edge of the groove to remove burrs.

[0040] Reset after processing: 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 clamping plates 8. The transmission roller 9 stops rotating. The steel lining is taken out manually, and the device returns to the initial state, preparing for the next cycle.

It cannot be determined that the specific embodiments of the present invention are limited thereto. For those of ordinary skill in the technical field to which the present invention pertains, without departing from the present invention, several simple deductions or substitutions can still be made, and all should be regarded as falling within the scope of patent protection determined by the claims submitted for the present invention.
