Description

Technical Field

[0001] This invention relates to the field of umbrella technology, and more specifically to a device for punching holes in umbrella ribs during umbrella manufacturing. Background Technology

[0002] Umbrellas are a common tool for people to avoid rain. Their main structure consists of an umbrella canopy and ribs. The umbrella canopy is used to block rain or sun, while the ribs support the umbrella canopy and guide its opening and closing. The ribs are made of high-strength metal or fiber materials, and the number of ribs varies depending on the size of the umbrella canopy. This ensures that the umbrella canopy provides sufficient support in windy and rainy conditions so that it will not collapse and can maintain a certain shape to block rain or sun.

[0003] During the production process of umbrella ribs, in order to better connect and integrate the umbrella ribs with umbrella rivets and other components, a drilling device is needed to process holes on the surface of the umbrella ribs to form through holes. The drilling device can quickly and accurately process holes in the umbrella ribs according to preset angles and hole sizes. It has a high degree of automation, and the hole sizes are uniform and the positioning is accurate, effectively improving the speed and efficiency of umbrella rib processing.

[0004] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: When the existing punching device punches holes in the umbrella ribs, the umbrella ribs are subjected to sudden and concentrated downward pressure generated by the punch during the punching process. Since the umbrella ribs need to be fixed during the punching process, the umbrella ribs are clamped and fixed by the fixing device and then pressed downward. If the punching position is not exactly in the relative position where the umbrella ribs are fixed by the fixing device, it is easy for the umbrella ribs to bend and deform after being punched. At the same time, the lower end of the punching will cause the surface of the umbrella ribs to bulge and have poor flatness. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings and deficiencies of the prior art by providing an umbrella rib punching device for umbrella processing that prevents the umbrella ribs from deforming during processing and achieves high flatness after processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rib drilling device for umbrella processing, comprising a base and a processing table fixedly installed on the top surface of the base. The top surface of the base is provided with internal push cylinders on both sides of the processing table. A pressure block is provided on the end of each internal push cylinder facing the processing table. A lifting frame is also provided on the processing table, and a downward pressing cylinder is installed on the lifting frame. A stamping device is connected to the lower end of the downward pressing cylinder. The processing table includes a placement plate fixedly installed on the top surface of the base and a placement groove integrally formed on the upper surface of the placement plate. The bottom surface of the placement groove has a grinding structure with its bottom end penetrating the bottom of the placement plate. Several rib support structures are symmetrically distributed on both sides of the placement groove within the placement plate. Each rib support structure includes a side push cylinder and a push-out frame located at the end of the side push cylinder. Several deformable columns are provided within the push-out frame. Each deformable column includes a sliding frame with a sliding groove integrally formed on its inner wall within the push-out frame and a sliding rod whose outer end is slidably disposed on the inner wall of the sliding groove. A return spring is provided between the end of the sliding rod and the inner wall of the sliding groove. The slide bar has a horizontal sliding bar with a polished outer wall at its end. The horizontal sliding bar has a bonding block at its end. The bonding block includes a silicone bonding block body and an arc-shaped groove integrally formed on one side of the bonding block body, penetrating the bonding block body from above. The inner wall of the arc-shaped groove has a 7-shaped rubber sheet. The outer wall of the rubber sheet has several hemispherical friction grooves integrally formed. The grinding structure includes a connecting plate and a sliding channel integrally formed in the connecting plate from top to bottom. A tray is slidably placed in the sliding channel. The bottom of the tray has an upward-pushing cylinder penetrating the top surface of the base. The top surface of the tray has a rotary motor. The top of the rotary motor is connected to a grinding disc. The stamping device includes a pressure plate connected to the bottom of the downward-pressing cylinder and a buffer groove integrally formed on the lower surface of the pressure plate. The pressure plate has several penetrating columns. The bottom of the penetrating columns is fixedly connected to a pressure block. A pressure spring is provided between the top surface of the pressure block and the bottom surface of the pressure plate, surrounding the penetrating columns. A pressing block is provided on the top surface of the pressure block at the corresponding position of the buffer groove. A punched block is provided at the bottom of the pressure block.

[0007] A further improvement is that the grinding disc includes a rotating ring fixed to the top of the rotary motor and several rotating plates fixedly disposed on the outer wall of the rotating ring, and several first abrasive blocks are embedded on the upper surface of the rotating plates.

[0008] A further improvement is that a first outer ring in the shape of a circle is integrally formed between several of the rotating plates, and a second frosted block with the same shape as the first outer ring is embedded in the upper surface of the first outer ring.

[0009] A further improvement is that a second outer ring in the shape of a circle is integrally formed between several of the rotating plates within the first outer ring, and a third frosted block of the same shape as the second outer ring is embedded in the upper surface of the second outer ring.

[0010] After adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0011] In use, the umbrella ribs to be punched are placed in the placement slot on the processing table, and the side-push cylinder of the umbrella rib support structure is activated to push the ejection frame. The deformable columns filled in the ejection frame adhere to and press against the surface of the umbrella rib. When pressure is generated, the sliding rods of the deformable columns move along the sliding groove and compress the return spring. Multiple deformable columns are simultaneously compressed, causing them to shrink and deform to varying degrees, thus adhering to the surface of the umbrella rib. The bonding blocks at their tops are pressed and adhered to the surface of the umbrella rib, providing additional fixed support for the umbrella rib. During punching, the outer walls of the transverse rods of the multiple deformable columns absorb the excessive pressure generated by punching, thereby fully supporting the umbrella rib, preventing bending deformation during punching, improving the fixing firmness, making the punched umbrella ribs straighter, and reducing the scrap rate.

[0012] After the stamping process, protrusions will appear on the lower surface of the stamped umbrella ribs. These protrusions can be removed by a grinding structure. First, an upward-pushing cylinder pushes the tray upward along the sliding channel, causing the rotary motor and grinding disc to move upward synchronously and fit against the lower surface of the punched umbrella ribs. The rotary motor is then started, causing the grinding disc to rotate. This causes the rotating plate and the first abrasive block on it to rotate and fit against the lower surface of the umbrella ribs for friction and grinding. This allows the protrusions on the lower surface of the umbrella ribs to be quickly rubbed off after punching, and the debris generated by the friction falls from the gaps between the multiple rotating plates. This results in a high degree of flatness on the surface of the formed umbrella ribs and prevents protrusions from affecting assembly. Attached Figure Description

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0025] See Figure 1-10As shown, the technical solution adopted in this specific embodiment is: a rib drilling device for umbrella processing, including a base 1 and a processing table 3 fixedly installed on the top surface of the base 1. An internal push cylinder 4 is also provided on both sides of the processing table 3 on the top surface of the base 1. A pressure block 5 is provided on the end of the internal push cylinder 4 facing the processing table 3. A lifting frame 6 is also provided on the processing table 3. A downward pressing cylinder 7 is installed on the lifting frame 6. A stamping device 8 is connected to the lower end of the downward pressing cylinder 7. The processing table 3 includes a placement plate 31 fixedly installed on the top surface of the base 1 and a placement groove 32 integrally formed on the upper surface of the placement plate 31. A grinding structure 33 with its bottom end penetrating the bottom of the placement plate 31 is provided on the bottom surface of the placement groove 32. Several rib support structures 34 are symmetrically distributed on both sides of the placement groove 32 within the placement plate 31. The umbrella rib support structure 34 includes a side-push cylinder 341 and an ejection frame 342 disposed at the end of the side-push cylinder 341. The ejection frame 342 contains several deformable columns 343. Each deformable column 343 includes a sliding frame 44 with an integrally formed sliding groove 46 on its inner wall within the ejection frame 342, and a sliding rod 42 with its outer end wall slidably disposed on the inner wall of the sliding groove 46. A return spring 45 is provided between the end of the sliding rod 42 and the inner wall of the sliding groove 46. A horizontal moving rod 41 with a polished outer wall is provided at the end of the sliding rod 42. An adhesive block 43 is provided at the end of the horizontal moving rod 41. The adhesive block 43 includes an adhesive block body 431 made of silicone material and an arc-shaped groove 432 integrally formed on one side of the adhesive block body 431, penetrating the adhesive block body 431 from above. The inner wall of the arc-shaped groove 432 has a 7-shaped groove. The rubber sheet 433 is integrally formed with several hemispherical friction grooves 434 on its outer wall. In use, the umbrella rib requiring punching is placed in the placement groove 32 on the processing table 3, and the side-push cylinder 341 of the umbrella rib support structure 34 is activated, pushing the ejector frame 342. This causes the deformable pillars 343 filled in the ejector frame 342 to adhere to and press against the surface of the umbrella rib. When pressure is generated, the sliding rod 42 of the deformable pillar 343 moves along the sliding groove 46, compressing the return spring 45, thereby displacing the end of the transverse rod 41, changing the length of the entire deformable pillar 343. Multiple deformable pillars 343 are simultaneously compressed, and different deformation amounts occur depending on their position on the umbrella rib, resulting in different deformations of the multiple deformable pillars 343. The shrinkage and deformation of the material adheres to the surface of the umbrella ribs, causing the adhesive block 43 at its tip to be pressed and adhered to the surface of the umbrella ribs. The adhesive block body 431 of the adhesive block 43 is made of silicone material and has an arc-shaped groove 432 on its surface. This allows the outer wall of the umbrella ribs to be inserted into the arc-shaped groove 432 and generate strong friction. At the same time, the rubber sheet 433 is compressed and deformed, causing the rubber sheet to wrap around the outer surface of the umbrella ribs and generate huge friction through the friction groove 434. At this time, the umbrella ribs can be frictionally anti-slip and reinforced, and additional support can be fixed by compression. At this time, stamping can be performed. The lifting frame 6 raises and lowers the pressing cylinder 7 and the stamping device 8. After reaching the appropriate position, the pressing cylinder 7 is activated, which quickly pushes the stamping device 8 to punch holes in the umbrella ribs. During the stamping process...The excessive pressure generated during stamping is absorbed by the outer wall of the transverse rod 41 of multiple deformable columns 343, thereby fully supporting the umbrella ribs, preventing bending deformation during stamping, improving fixing firmness, making the punched umbrella ribs straighter, and reducing the scrap rate;

[0026] In actual testing, the umbrella rib support structure of this invention was used to fix an umbrella rib with a length of 300mm and a cross-sectional diameter of 2.5mm. Measurements showed that without this support structure, the average bending deformation of the umbrella rib after punching was 0.8mm; with this support structure, the bending deformation was reduced to below 0.1mm, demonstrating a significant deformation suppression effect. The scrap rate decreased from 12% to less than 2%. Furthermore, the bonding block 43, made of silicone and equipped with an arc-shaped groove 432 and a friction groove 434, achieved a static friction coefficient of over 0.6 on the umbrella rib surface during actual clamping tests. This provides better anti-slip and fixing effects compared to ordinary rubber clamping blocks (friction coefficient approximately 0.3), and no umbrella rib displacement occurred during the stamping process.

[0027] The grinding structure 33 includes a connecting plate 331 and a sliding channel 332 integrally formed within the connecting plate 331. A tray 335 is slidably disposed within the sliding channel 332. A push cylinder 35 penetrating the top surface of the base 1 is provided at the bottom of the tray 335. A rotary motor 334 is provided on the top surface of the tray 335. A grinding disc 333 is connected to the top of the rotary motor 334. The grinding disc 333 includes a rotating ring 51 fixed to the top of the rotary motor 334 and several rotating plates 52 fixedly disposed on the outer wall of the rotating ring 51. Several first abrasive blocks 53 are embedded in the upper surface of the rotating plates 52. After stamping, a protrusion will be generated on the lower surface of the stamped umbrella rib. This protrusion can be removed by the grinding structure 33. First, the push cylinder 35 is used to push the tray 335 along... The sliding channel 332 is pushed upward, which causes the rotary motor 334 and the polishing disc 333 to move upward synchronously and fit against the lower surface of the punched umbrella rib. The rotary motor 334 is started, which drives the polishing disc 333 to rotate, thereby causing the rotating plate 52 to rotate under the action of the rotating ring 51. This causes the first abrasive block 53 on the rotating plate 52 to rotate. The first abrasive block 53 has a rough surface and a high coefficient of friction. When it contacts the lower surface of the umbrella rib, it can rub and remove the protrusions. This allows the umbrella rib to quickly rub the protrusions on the lower surface of the umbrella rib after punching, and the debris generated by friction falls from the gap between the multiple rotating plates 52 through centrifugal force. This results in a high degree of flatness on the surface of the formed umbrella rib and prevents the protrusions caused by punching from affecting the assembly.

[0028] This grinding structure is used to grind the protrusions on the lower surface of the punched umbrella ribs, with a grinding time of 3 seconds per hole. Surface roughness measurements show that the roughness Ra of the protruding area was approximately 6.3 μm before grinding, and decreased to below 0.8 μm after grinding, significantly improving surface smoothness and fully meeting the requirements for umbrella rib assembly.

[0029] A first outer ring 54 in the shape of a circle is integrally formed between several rotating plates 52. A second abrasive block 56 with the same shape as the first outer ring 54 is embedded on the upper surface of the first outer ring 54, which is conducive to continuous fine polishing of the lower surface of the umbrella rib after forming through the first outer ring 54, thereby improving the polishing effect and polishing speed.

[0030] Between several rotating plates 52, a second outer ring 55 in the shape of a circle is integrally formed within the first outer ring 54. A third abrasive block 57 with the same shape as the second outer ring 55 is embedded on the upper surface of the second outer ring 55, which is conducive to fine polishing of the lower surface of the umbrella rib over a larger area, further improving the polishing effect and polishing speed.

[0031] Under the same polishing time (3 seconds), when only the first abrasive block 53 on the rotating plate 52 is used, the average surface roughness Ra is 1.2 μm; after adding the first outer ring 54 and the second outer ring 55 for multi-stage polishing, the Ra value is further reduced to 0.6 μm, and the polishing uniformity and efficiency are improved by about 30%.

[0032] The stamping device 8 includes a pressure plate 81 connected to the bottom end of the pressing cylinder 7 and a buffer groove 82 integrally formed on the lower surface of the pressure plate 81. The pressure plate 81 has several penetrating posts 83, and pressure blocks 84 are fixedly connected to the bottom ends of the penetrating posts 83. A pressure spring 85 is provided between the top surface of the pressure block 84 and the bottom surface of the pressure plate 81, surrounding the penetrating posts 83. A retaining block 86 is provided on the top surface of the pressure block 84 at the corresponding position in the buffer groove 82. A punched block 87 is provided at the bottom end of the pressure block 84. During stamping, the pressure plate 81 is first lowered, and the punched block 87 at the bottom of the pressure block 84 is then pressed against the umbrella... When the pressure cylinder 7 is activated, it causes the pressure plate 81 to descend rapidly. During the descent, the pressure spring 85 surrounding the penetrating column 83 is first squeezed. After the pressure spring 85 is squeezed to its limit, the pressing block 86 at the top of the pressure block 84 presses against the inner wall of the buffer groove 82. At this time, the pressure can be fully output to the punching block 87 for punching. This allows the pressure release to have a buffer process, avoiding the sudden application of excessive pressure, which would cause the umbrella rib to bend due to excessive pressure during punching. This ensures the straightness of the umbrella rib during the punching process.

[0033] By monitoring pressure changes during the stamping process using a pressure sensor, traditional stamping devices without a buffer structure can reach a peak pressure of 800N at the moment of contact with the umbrella ribs, which can easily lead to local deformation of the umbrella ribs. This invention, through the cooperation of the pressure spring 85 and the buffer groove 82, reduces the peak pressure to below 500N and extends the pressure rise time by about 40%, effectively avoiding impact deformation.

[0034] The working principle of this invention is as follows: In use, the umbrella ribs requiring punching are placed in the placement slot 32 on the processing table 3. The side-push cylinder 341 of the umbrella rib support structure 34 is activated, pushing the ejector frame 342. This causes the deformable pillars 343 filled within the ejector frame 342 to adhere to and press against the surface of the umbrella rib. When pressure is generated, the sliding rod 42 of the deformable pillar 343 moves along the sliding groove 46, compressing the return spring 45. This causes displacement at the end of the transverse rod 41, changing the length of the entire deformable pillar 343. Multiple deformable pillars 343 are simultaneously compressed, and different deformation amounts occur depending on their position on the umbrella rib. Consequently, the multiple deformable pillars 343 shrink and deform to varying degrees, adhering to the umbrella rib. The surface of the umbrella rib is pressed and adhered to the surface of the umbrella rib by the adhesive block 43 at its tip. The adhesive block body 431 of the adhesive block 43 is made of silicone material and has an arc groove 432 on its surface. This allows the outer wall of the umbrella rib to be inserted into the arc groove 432 and generate strong friction. At the same time, the rubber sheet 433 is compressed and deformed, and the rubber sheet wraps around the outer surface of the umbrella rib and generates huge friction through the friction groove 434. At this time, the umbrella rib can be frictionally anti-slip and reinforced, and additional support can be fixed by compression. At this time, stamping can be performed. The lifting frame 6 raises and lowers the pressing cylinder 7 and the stamping device 8. After reaching the appropriate position, the pressing cylinder 7 is activated, which quickly pushes the stamping device 8 to punch holes in the umbrella rib. During stamping, the excessive pressure generated by the stamping is absorbed by the outer wall of the transverse rods 41 of multiple deformation columns 343, thereby fully supporting the umbrella ribs, preventing bending deformation during the stamping process, improving the fixing firmness, making the punched umbrella ribs straighter, and reducing the scrap rate. At the same time, after the stamping is completed, a protrusion will appear on the lower surface of the stamped umbrella ribs, which can be removed by the grinding structure 33. First, the upward push cylinder 35 pushes the tray 335 upward along the sliding channel 332, thereby causing the rotary motor 334 and the grinding disc 333 to move upward synchronously and fit against the lower surface of the punched umbrella ribs. The rotary motor 334 is started, causing the rotary motor 334 to drive the grinding disc 333 to rotate. This causes the rotating plate 52 to rotate under the action of the rotating ring 51, thereby causing the first abrasive block 53 on the rotating plate 52 to rotate. The first abrasive block 53 has a rough surface and a high coefficient of friction. When it contacts the lower surface of the umbrella rib, it can remove the protrusions by friction. This allows the protrusions on the lower surface of the umbrella rib to be quickly rubbed after punching, and the debris generated by friction falls from the gap between the multiple rotating plates 52 through centrifugal force. This results in a high degree of flatness on the surface of the formed umbrella rib and prevents the protrusions caused by punching from affecting assembly. The umbrella rib punching device of the present invention has significant advantages in terms of umbrella rib fixing, punching buffer, and grinding flatness. It can greatly improve the processing quality and efficiency of umbrella ribs and is suitable for industrial mass production.
