Description

Technical Field

[0001] The invention relates to the technical field of glass fiber reinforced plastic punching, and more specifically, to punching equipment and a punching method for producing high-strength and lightweight glass fiber reinforced plastic protective parts. Background Art

[0002] FRP, the full name of which is glass fiber reinforced plastic, is a composite material with synthetic resin as the matrix material and glass fiber and its products as the reinforcing material. It has high strength and hardness. At the same time, compared with metal materials, it has a lower density, which makes FRP products both strong and light.

[0003] In order to connect with other FRP guards, it is necessary to punch holes on the surface of the FRP guards. In order to meet different connection methods, holes of different specifications need to be punched on the surface of the FRP guards, so that the FRP guards can be connected to each other by plugging and bolting. In order to meet specific functional requirements, the arrangement of the stamped holes of some FRP guards is different.

[0004] The existing FRP protective parts punching equipment can only punch holes of the same specification. When the FRP protective parts need to punch other types of holes, the staff needs to take them to another device for punching. This process delays the punching time of the FRP protective parts, resulting in a decrease in the FRP punching speed and production efficiency.

[0005] When the punched holes of some FRP protective parts need to be arranged, personnel are required to manually move the FRP protective parts so that holes of different arrangements and combinations can be punched on the surface of the FRP protective parts. Manually moving the FRP protective parts is cumbersome to operate, and the moving values ​​are not accurate. It is impossible to automatically punch holes of multiple arrangements at the same time, resulting in the inability to accurately align the holes when installing the subsequent FRP protective parts.

[0006] Therefore, it is necessary to design a FRP protective part stamping equipment with adjustable stamping shape and adjustable hole arrangement to improve the above-mentioned technical problems. Summary of the invention

[0057] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0058] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0059] For example, see Figure 1-12 The present invention provides the following technical solutions: punching equipment for producing high-strength lightweight fiberglass protective parts, including a second base frame 2 and a first base frame 1 arranged on one side of the second base frame 2, a punching mechanism 5 is arranged on the upper side of the first base frame 1, a sliding mechanism 4 is arranged on the upper side of the second base frame 2, and a first grinding mechanism 6 and a second grinding mechanism 8 are respectively arranged on both sides of the sliding mechanism 4, and the first grinding mechanism 6 and the second grinding mechanism 8 have the same structure.

[0060] Specifically, the punching mechanism 5 is used to punch holes of different shapes and different arrangements on the surface of the FRP, the sliding mechanism 4 is used to control the movement of the FRP protective part, the clamping mechanism 3 is used to clamp the four sides of the FRP, and the first grinding mechanism 6 and the second grinding mechanism 8 are used to grind holes of different shapes and different arrangements inside the FRP protective part.

[0061] See also Figure 2 and Figure 3 The sliding mechanism 4 includes a base 43, which is fixedly connected to the upper side of the second base frame 2, and a slide rail 41 is fixedly connected to the upper side of the base 43. A first servo motor 42 is fixedly connected to one side of the base 43, and a screw rod 44 is fixedly connected to the output end of the first servo motor 42. The other end of the screw rod 44 is connected to the bearing of the base 43, and a first slide seat 45 and a second slide seat 48 are slidably connected to the upper side of the screw rod 44 respectively. The first slide seat 45 and the second slide seat 48 are connected to the ball bearings of the screw rod 44 inside, and a collection box 47 is fixedly connected between the first slide seat 45 and the second slide seat 48, and a filter screen 46 is fixedly connected to the inside of the collection box 47.

[0062] Specifically, the rotation of the output end of the first servo motor 42 is used to control the rotation of the screw rod 44, thereby controlling the movement of the first slide 45 and the second slide 48, and then controlling the movement of the fiberglass protective part clamped by the clamping mechanism 3. The collection box 47 is used to collect waste materials during stamping of the fiberglass protective part. The filter screen 46 is used to filter the dust during grinding and separate it from the fiberglass waste to prevent the dust from being mixed with the fiberglass waste during subsequent waste recycling, resulting in the waste being unable to be recycled.

[0063] See also Figure 4-Figure 6, a clamping mechanism 3 is provided on the upper side of the collecting box 47 and the second slide 48, and the two clamping mechanisms 3 have the same structure. A glass fiber reinforced plastic stamping part 7 is provided between the two clamping mechanisms 3. The clamping mechanism 3 includes a first cylinder 31, which is fixedly connected to the first slide 45, and a fixed frame 36 is fixedly connected to one side of the first cylinder 31. A connecting rod 32 is hinged at the output end of the first cylinder 31, and a first tripod 33 and a second tripod 37 are hinged at the upper and lower ends of the connecting rod 32, respectively. Both ends of the first tripod 33 and the second tripod 37 are provided with a slide groove, and the slide grooves of the first tripod 33 and the second tripod 37 are slidably connected with a second slide column 39 and a first slide column 35, and a second right-angle clamping plate 38 is fixedly connected to the outer side of the second slide column 39, and a first right-angle clamping plate 34 is fixedly connected to the outer side of the first slide column 35, one end of the second right-angle clamping plate 38 is hinged to one end of the fixed frame 36, and one end of the first right-angle clamping plate 34 is hinged to the other end of the fixed frame 36.

[0064] Specifically, in the initial state, the output end of the first cylinder 31 is in a fully retracted state, the first right-angle clamp 34 and the second right-angle clamp 38 are in an open state, and the shape is a W shape at this time. The extension of the output end of the first cylinder 31 controls the first tripod 33 and the second tripod 37 to move, the second slide column 39 and the first slide column 35 slide inside the slide groove of the first tripod 33 and the second tripod 37, and the first right-angle clamp 34 and the second right-angle clamp 38 start to rotate. When the output end of the first cylinder 31 is fully extended, the first right-angle clamp 34 and the second right-angle clamp 38 are in a closed state, and the shape is a U shape at this time. The first right-angle clamp 34 and the second right-angle clamp 38 clamp and fix the four sides of the fiberglass protective component.

[0065] By extending and retracting the output end of the first cylinder 31, the first right-angle clamp 34 and the second right-angle clamp 38 are controlled to open or close, thereby clamping and fixing the four sides of the FRP protective member, effectively preventing the FRP protective member from shifting to the other two sides when the two sides of the FRP protective member are clamped and stamped, causing the stamping holes to be offset, thereby achieving the effect of clamping the four sides of the FRP protective member at the same time.

[0066] In the second embodiment, when the punched holes of some FRP protective parts need to be arranged, personnel are required to manually move the FRP protective parts so that holes of different arrangements and combinations are punched on the surface of the FRP protective parts. Manually moving the FRP protective parts is cumbersome to operate, and the movement value is not accurate. It is impossible to automatically punch holes of multiple arrangements at the same time, resulting in the inability to accurately align the holes when the FRP protective parts are subsequently installed. Therefore, the following structure is designed to solve the above technical problems.

[0067] See also Figure 7The punching mechanism 5 includes a bracket 51, one side of the bracket 51 is fixedly connected with a fixed plate 54, the interior of the fixed plate 54 is respectively provided with a first arrangement component 52 and a second arrangement component 53, and the lower side of the fixed plate 54 is respectively provided with a first pressure head adjustment component 56 and a second pressure head adjustment component 55, and the first pressure head adjustment component 56 and the second pressure head adjustment component 55 have the same structure.

[0068] Specifically, the first arrangement component 52 and the second arrangement component 53 are used to arrange and combine the punched holes, and the first press head adjustment component 56 and the second press head adjustment component 55 are used to adjust the shapes of the holes to be punched.

[0069] See also Figure 8 The first arrangement component 52 includes a first sliding plate 523, one side of the first sliding plate 523 is provided with a tooth column, the other side of the first sliding plate 523 is slidably connected to the fixed plate 54, the upper side of the first sliding plate 523 is fixedly connected to the second cylinder 521, the output end of the second cylinder 521 passes through the first sliding plate 523 and is fixedly connected to the first pressing plate 524, and two first sliding rods 522 are respectively provided on the upper side of the first pressing plate 524, and the first sliding rods 522 are both slidably connected to the first sliding plate 523.

[0070] Specifically, the extension and retraction of the output end of the second cylinder 521 is used to control the first pressing plate 524 to move up and down, thereby controlling the punching head to punch the fiberglass reinforced plastic protective piece.

[0071] The second arrangement component 53 includes a second sliding plate 533, one side of the second sliding plate 533 is provided with a gear column, the other side of the second sliding plate 533 is slidably connected to the fixed plate 54, the upper side of the second sliding plate 533 is fixedly connected to the third cylinder 531, the output end of the third cylinder 531 passes through the second sliding plate 533 and is fixedly connected to the second pressing plate 534, the upper side of the second pressing plate 534 is respectively provided with two second sliding rods 532, and the second sliding rods 532 are both slidably connected to the second sliding plate 533.

[0072] The working principle of the second arrangement component 53 is the same as that of the first arrangement component, and will not be elaborated on here.

[0073] A gear 541 is meshed between the first sliding plate 523 and the second sliding plate 533 . A first motor 542 is fixedly connected to the lower side of the fixed plate 54 . An output end of the first motor 542 passes through the fixed plate 54 and is fixedly connected to the gear 541 .

[0074] Specifically, the rotation of the output end of the first motor 542 is used to control the rotation of the gear 541, so that the second sliding rod 532 and the second sliding plate 533 slide in different directions respectively, thereby arranging and combining the punched holes.

[0075] See also Fig.12 , a, b and c are three different arrangements of holes on the surface of the FRP protective part. The square is a punch head. In the initial state, the arrangement of the two punch heads is a. When the output end of the first motor 542 rotates forty-five degrees, the two punch heads are staggered by half. When the output end of the first motor 542 rotates ninety degrees, the two punch heads are completely staggered.

[0076] When the arrangement of the holes to be punched is a, the extension of the output end of the second cylinder 521 controls the first pressing plate 524 to move downward, thereby controlling the two punching heads to punch the fiberglass protective plate.

[0077] When the arrangement of holes to be punched is b, the output end of the first motor 542 rotates forty-five degrees. At this time, the two punching heads are staggered by half. The output end of the first motor 542 rotates forty-five degrees, and the output end of the second cylinder 521 extends to control the first pressing plate 524 to move downward, thereby controlling the two punching heads to punch the fiberglass protective plate.

[0078] When the arrangement of holes to be punched is c, the output end of the first motor 542 rotates ninety degrees. At this time, the two punching heads are completely staggered. The rotation of the output end of the first motor 542 and the extension of the output end of the second cylinder 521 control the first pressing plate 524 to move downward, thereby controlling the two punching heads to punch the fiberglass protective plate.

[0079] By adjusting the rotation angle of the output end of the first motor 542, the two punching heads are controlled to punch out holes with different arrangements on the surface of the fiberglass protective component, effectively avoiding the phenomenon that the staff manually moves the fiberglass, resulting in inaccurate arrangement of the punched holes, and achieving the effect of automatic arrangement of the punched holes and accurate arrangement of the punched holes.

[0080] Embodiment three: In the existing FRP protective part punching equipment, one punching device can only punch holes of the same specification. When the FRP protective part needs to punch other types of holes, the staff needs to take it to another device for punching. This process delays the punching time of the FRP protective part, resulting in a decrease in the FRP punching speed and production efficiency. Therefore, the following structure is designed to solve the above technical problems.

[0081] See also Fig. 9 and Fig.10The first pressure head adjustment assembly 56 includes a guide sliding block 567, which is fixedly connected to the lower side of the first pressure plate 524. A positioning column 563 is fixedly connected to the inside of the guide sliding block 567, and a circular punch 564 is fixedly connected to the lower side of the positioning column 563. A square punch 565 is slidably connected to the outer side of the circular punch 564. Semicircular punches 566 are slidably connected to both sides of the square punch 565. A first hydraulic cylinder 561 is provided on the upper side of each semicircular punch 566. The first hydraulic cylinder 561 is fixedly connected to the guide sliding block 567 and a first pressure block is fixedly connected to the output end. A second hydraulic cylinder 562 is provided on the upper side of the square punch 565. The second hydraulic cylinder 562 is fixedly connected to the guide sliding block 567 and a second pressure block is fixedly connected to the output end.

[0082] Specifically, the extension of the output end of the first hydraulic cylinder 561 is used to control the first pressure block to press the semicircular punch 566, and the extension of the output end of the second hydraulic cylinder 562 is used to control the second pressure block to press the square punch 565. In the initial state, the output end of the first hydraulic cylinder 561 and the output end of the second hydraulic cylinder 562 are both in a retracted state.

[0083] Two first positioning grooves are provided on the upper side of the square punch 565, two second positioning grooves are provided on the upper side of the circular punch 564, a first platform is provided in the middle of the square punch 565, and a second platform is provided on one side of the semicircular punch 566. The first positioning groove supports the second platform, and the second positioning groove supports the first platform.

[0084] Specifically, since the circular punch 564 is fixed by the positioning column 563, the square punch 565 is supported by the circular punch 564, and the semicircular punch 566 is supported by the square punch 565, the semicircular punch 566 and the square punch 565 will not fall downward.

[0085] When it is necessary to punch a circular hole, the extension of the output end of the second cylinder 521 controls the first pressure plate 524 to move downward, thereby controlling the circular punch 564, the semicircular punch 566 and the square punch 565 to move downward. When the lower ends of the circular punch 564, the semicircular punch 566 and the square punch 565 simultaneously contact the top surface of the fiberglass protective member, since the circular punch 564 is fixed by the positioning column 563, and the upper ends of the semicircular punch 566 and the square punch 565 are not pressed, when the output end of the second cylinder 521 is fully extended, the semicircular punch 566 and the square punch 565 are supported by the top surface of the fiberglass protective member, causing it to lift upward, and the circular punch 564 moves downward to punch a circular hole on the surface of the fiberglass protective member.

[0086] When it is necessary to punch a square hole, the output end of the second hydraulic cylinder 562 extends to control the second pressing block to press the square punch 565. The extension of the output end of the second cylinder 521 controls the first pressing plate 524 to move downward, thereby controlling the circular punch 564, the semicircular punch 566 and the square punch 565 to move downward. When the lower ends of the circular punch 564, the semicircular punch 566 and the square punch 565 simultaneously contact the top surface of the fiberglass protective member, since the circular punch 564 is fixed by the positioning column 563, the square punch 565 is pressed by the second pressing block, while the upper end of the semicircular punch 566 is not pressed. When the output end of the second cylinder 521 is fully extended, the semicircular punch 566 is supported by the top surface of the fiberglass protective member, causing it to lift upward, and the circular punch 564 and the square punch 565 move downward to punch a square hole on the surface of the fiberglass protective member.

[0087] When it is necessary to punch an elliptical hole, the output end of the first hydraulic cylinder 561 extends to control the first pressing block to press the semicircular punch 566, the output end of the second hydraulic cylinder 562 extends to control the second pressing block to press the square punch 565, and the extension of the output end of the second cylinder 521 controls the first pressing plate 524 to move downward, thereby controlling the circular punch 564, the semicircular punch 566 and the square punch 565 to move downward. When the lower ends of the circular punch 564, the semicircular punch 566 and the square punch 565 simultaneously contact the top surface of the fiberglass protective member, since the circular punch 564 is fixed by the positioning column 563, the square punch 565 is pressed by the second pressing block, and the semicircular punch 566 is pressed by the first pressing block. When the output end of the second cylinder 521 is fully extended, the semicircular punch 566, the circular punch 564 and the square punch 565 move downward to punch an elliptical hole on the surface of the fiberglass protective member.

[0088] By combining the semicircular punch 566, the circular punch 564 and the square punch 565 into a spliced ​​punching head, the shapes of the punching heads can be combined into circular, square and elliptical shapes respectively under the sliding of the semicircular punch 566, the circular punch 564 and the square punch 565 according to actual needs, thereby effectively preventing the fiberglass protective part from being taken to another device for punching when other types of holes need to be punched, thereby achieving the effect of adjustable stamping shape and high stamping efficiency.

[0089] Embodiment 4: Since FRP is a composite of glass fiber and resin, it has high hardness and brittleness. When stamping, burrs are easily generated on the edge of the material due to stress concentration. After stamping, the inner wall of the hole needs to be polished to prevent the subsequent FRP protective parts from being unable to be inserted into the punched hole during installation. The existing stamping hole polishing is single and cannot polish stamping holes of different shapes and different arrangements, resulting in slower polishing speed and lower hole polishing efficiency. Therefore, the following structure is designed to solve the above technical problems.

[0092] In the initial state, the elliptical grinding block 65 is horizontally downward. When a circular hole needs to be polished, the output end of the second motor 64 rotates one hundred and twenty degrees clockwise, thereby rotating the square grinding block 61, the circular grinding block 62 and the elliptical grinding block 65. At this time, the circular grinding block 62 is horizontally downward, and the output end of the third hydraulic cylinder 66 extends and retracts back and forth, controlling the circular grinding block 62 to frictionally polish the inner wall of the circular hole back and forth.

When it is necessary to grind the holes in arrangement a, the output end of the third hydraulic cylinder 66 retracts and contracts back and forth to control the grinding block to grind the holes.

[0098] The square grinding block 61, the circular grinding block 62 and the elliptical grinding block 65 are moved by controlling the extension and retraction of the output end of the fourth hydraulic cylinder 68, so as to grind holes of different arrangements. The rotation of the output end of the second motor 64 is used to control the rotation of the square grinding block 61, the circular grinding block 62 and the elliptical grinding block 65, so as to adjust the grinding block suitable for the shape of the punched hole according to its shape, thereby achieving the effect of adaptive grinding of holes of different shapes and different hole arrangements.
