[0002] Hydraulic bending machines are one of the most widely used types of bending machines, and are widely used in various metal processing fields. In the machinery manufacturing industry, they are used to process the shells and brackets of various mechanical parts. In the automotive manufacturing industry, they can be used to produce car body panels and frame components. In electronic equipment manufacturing, they are often used to process products such as chassis and cabinets. In the building decoration industry, they can bend aluminum alloy, stainless steel and other plates to make door and window frames, decorative lines and so on.

[0003] Existing hydraulic bending machines, when hydraulically bending sheet metal, cause air to be drawn into the hydraulic oil during operation. This air forms tiny bubbles in the oil, and when these bubbles burst, they may produce tiny particulate impurities, which can affect the performance of the hydraulic system, causing unstable flow and vibration, resulting in shaking during sheet metal bending. Therefore, we have introduced a sheet metal anti-shake bending machine. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 - Figure 6A sheet metal anti-shaking bending machine includes a workbench body 1, a hydraulic telescopic rod 2 on the top of the workbench body 1, an upper mold body 3 fixedly mounted on the telescopic end of the hydraulic telescopic rod 2, a support base 4 on the outer wall of the workbench body 1, a lower mold body 5 fixedly mounted on the top of the support base 4, a baffle body 6 on the outer wall of the support base 4, a sheet metal body 7 on the top of the lower mold body 5, a sliding groove 8 on the outer wall of the baffle body 6, a fixing block 9 slidably connected to the outer wall of the workbench body 1, a pulley 10 rotatably connected to the inner wall of the fixing block 9, a fixing component 11 on the top of the fixing block 9, and a fixing component 11 on the outer wall of the fixing block 9. An air pump 12 is fixedly installed on the wall. An air pipe 13 is fixedly connected to the outer wall of the air pump 12. A square box 14 is fixedly installed on the outer wall of the workbench body 1. A hydraulic pump 15 is fixedly installed on the outer wall of the square box 14. A connecting pipe 16 is fixedly connected to the outer wall of the hydraulic pump 15. A connecting pipe 27 is fixedly connected to the bottom of the hydraulic pump 15. One end of a connecting pipe 318 is fixedly connected to the inner wall of the square box 14. A hydraulic pump 29 is fixedly connected to the other end of the connecting pipe 318. A connecting pipe 420 is fixedly connected to the outer wall of the hydraulic pump 219. A filter assembly 21 and a scraping assembly 22 are respectively provided in the inner cavity of the square box 14.

[0029] The filter assembly 21 includes a motor 211, an annular sleeve 212 is fixedly sleeved on the outer edge of the output shaft of the motor 211, and filter screen cylinder one 213 and filter screen cylinder two 214 are fixedly installed on the top of the annular sleeve 212 respectively.

[0030] In the above structure, by configuring the filter assembly 21, the hydraulic pump 15 is activated, which draws hydraulic oil from the inner cavity of the hydraulic telescopic rod 2 through the connecting pipe 16 and delivers it to the inner cavity of the filter cylinder 214 through the connecting pipe 17. Then, the motor 211 is activated, causing the outer edge of the output shaft of the motor 211 to drive the annular sleeve 212 to rotate. This causes the filter cylinders 213 and 214 at the top of the annular sleeve 212 to also rotate, thus rotating the inner cavity of the filter cylinder 214. As the hydraulic oil rotates in the filter cylinder 214, larger solid particles or impurities in the hydraulic oil are thrown into the inner wall of the filter cylinder 214. At the same time, smaller solid particles or impurities in the hydraulic oil are also thrown into the inner wall of the filter cylinder 213. Then, by starting the hydraulic pump 219, the hydraulic pump 219 draws the filtered hydraulic oil from the inner cavity of the square box 14 through the connecting pipe 318, and then transmits the hydraulic oil to the inner cavity of the hydraulic telescopic rod 2 through the connecting pipe 420.

[0031] In a preferred embodiment: the fixing component 11 includes a cylinder 111, a support rod 115 is slidably sleeved on the inner wall of the cylinder 111, a solenoid valve 112 is provided on the outer wall of the cylinder 111, an mounting base 113 is fixedly installed on the top of the fixing block 9, one end of a connecting rod 114 is rotatably connected to the outer wall of the mounting base 113, a contact rod 117 is rotatably connected to the other end of the connecting rod 114, a spring 116 is provided on the outer wall of the support rod 115, one end of a connecting rod 118 is rotatably connected to the outer wall of the connecting rod 114, a square plate 119 is rotatably connected to the other end of the connecting rod 118, and a connecting rod 110 is rotatably connected to the outer wall of the square plate 119.

[0032] In a preferred embodiment: the top shape of the support rod 115 is the same as the bottom shape of the square plate 119, and the top and bottom of the support rod 115 are connected through each other. The cylinder 111, solenoid valve 112, mounting base 113, connecting rod 114, support rod 115, spring 116, contact rod 117, connecting rod 118, square plate 119 and connecting rod 110 are regarded as a movable component, and the movable component is arranged on both sides of the outer wall of the baffle body 6 of the plate body 7.

[0033] In the above structure, the arrangement of the cylinder 111, solenoid valve 112, mounting base 113, connecting rod 114, support rod 115, spring 116, contact rod 117, connecting rod 118, square plate 119, and connecting rod 110 allows the air pump 12 to be activated, delivering gas to the inner cavity of the cylinder 111 through the air pipe 13. This causes the support rod 115 to slide along the inner wall of the cylinder 111 under the pressure of the gas. As the support rod 115 slides, the spring 116 is compressed, and simultaneously, the support rod 115 drives the connecting rods 118 and 110 to rotate. The contact rod 117, pushed by the connecting rod 118 and the connecting rod 110, will cause the connecting rod 114 to rotate 90 degrees, thereby fixing the bottom of the contact rod 117 to the top of the plate body 7. Then, by activating the solenoid valve 112, the gas inside the cylinder 111 will be depressurized and discharged, causing the support rod 115 to reset the contact rod 117, the connecting rod 118, the square plate 119, and the connecting rod 110 under the compression and rebound of the spring 116. The same operation can also be used to fix and reset the movable component on the other side of the baffle body 6 to the plate body 7.

[0034] In a preferred embodiment: the scraping component 22 includes a second groove 221, an annular slider 222 is slidably connected to the inner wall of the second groove 221, a second spring 223 is provided at the top of the annular slider 222, a sealing plate 224 is fixedly assembled at the bottom of the annular slider 222, an air pump 225 is fixedly installed on the outer wall of the square box 14, an air pipe 226 is fixedly connected to the outer wall of the air pump 225, and a solenoid valve 227 is provided on the outer wall of the air pipe 226;

[0035] In a preferred embodiment: the outer wall of the sealing sheet 224 has the same shape as the inner wall of the second slide groove 221, and the outer wall of the second spring 223 is slidably fitted to the inner wall of the second slide groove 221; the inner wall of the annular slider 222 has the same shape as the outer wall of the second filter cylinder 214 and the first filter cylinder 213, and the inner wall of the annular slider 222 is slidably fitted to the outer wall of the second filter cylinder 214 and the first filter cylinder 213.

[0036] In the above structure, by setting the annular slider 222, the second air pump 225 is activated, which transmits gas to the bottom of the second slide groove 221 through the second air pipe 226. Under the push of the gas, the annular slider 222 drives the sealing plate 224 to slide along the inner wall of the second slide groove 221. At the same time, when the annular slider 222 and the sealing plate 224 slide, the second spring 223 is also compressed. When the inner wall of the annular slider 222 slides along the outer wall of the first filter cylinder 213 and the second filter cylinder 214, the impurities and particles filtered on their outer walls are scraped off. At the same time, by activating the second solenoid valve 227, the gas in the inner cavity of the second slide groove 221 is depressurized and discharged through the second air pipe 226. Thus, the annular slider 222 and the sealing plate 224 are reset under the compression and rebound of the second spring 223.

[0037] In a preferred embodiment: the outer wall shape of the pulley 10 is the same as the inner wall shape of the slide groove 8, and the pulley 10 is slidably fitted to the inner wall of the slide groove 8.

[0038] In the above structure, by setting the slide groove 8 and the pulley 10, the outer wall of the pulley 10 will slide along the inner wall of the slide groove 8.

[0039] In a preferred embodiment: the outer walls of filter cylinder 1 213 and filter cylinder 2 214 are respectively provided with a plurality of holes, and the plurality of holes are respectively connected to filter cylinder 1 213 and filter cylinder 2 214 through the holes, and the diameter of the holes on the outer walls of the two filter cylinders 1 213 is smaller than the diameter of the holes on the outer walls of the two filter cylinders 214.

[0040] In the above structure, the arrangement of filter cylinder 1 213 and filter cylinder 214 allows the several holes on the outer wall of filter cylinder 214 to filter larger solid particles or impurities in the hydraulic oil, while the several holes on the outer wall of filter cylinder 1 213 can filter smaller solid particles or impurities in the hydraulic oil, thereby achieving the effect of efficient filtration of hydraulic oil.

[0041] Working principle: When in use, the hydraulic pump 15 is started, which draws hydraulic oil from the inner cavity of the hydraulic telescopic rod 2 through the connecting pipe 16 and delivers it to the inner cavity of the filter cylinder 214 through the connecting pipe 27. Then, the motor 211 is started, causing the outer edge of the output shaft of the motor 211 to drive the annular sleeve 212 to rotate. This causes the filter cylinders 213 and 214 at the top of the annular sleeve 212 to rotate as well. Under the rotation of the filter cylinder 214, the lubricating fluid in the inner cavity of the filter cylinder 214 is filtered through several holes on the outer wall of the filter cylinder 214, which then filter larger solid particles or... Impurities are filtered out, and several holes on the outer wall of the filter screen cylinder 213 filter out smaller solid particles or impurities in the lubricating fluid. Then, by starting the hydraulic pump 2 19, the hydraulic pump 2 19 draws the filtered hydraulic oil from the inner cavity of the square box 14 through the connecting pipe 3 18, and then transmits the hydraulic oil to the inner cavity of the hydraulic telescopic rod 2 through the connecting pipe 4 20. This achieves the filtration of the hydraulic oil in the inner cavity of the upper mold body 3, maintains the cleanliness of the hydraulic oil in the inner cavity of the upper mold body 3, and avoids the impact of impurities and contaminants in the hydraulic oil on the performance of the hydraulic system, as well as the valve core jamming, unstable flow, and vibration caused by such contaminants.

[0042] Simultaneously, by activating air pump 225, air pump 225 transmits gas to the bottom of slide groove 221 through air pipe 226. Under the push of the gas, the annular slider 222 drives the sealing plate 224 to slide along the inner wall of slide groove 221. At the same time, when the annular slider 222 and the sealing plate 224 slide, they also drive the spring 223 to be compressed. When the inner wall of the annular slider 222 slides along the outer wall of filter cylinder 1 213 and filter cylinder 2 214, it scrapes off the impurities and particles filtered on their outer walls. At the same time, by activating solenoid valve 227, the solenoid valve 227 releases the gas in the inner cavity of slide groove 221 through air pipe 226. Thus, the annular slider 222 and the sealing plate 224 are reset under the compression and rebound of spring 223.

[0043] Then, when the sheet metal is being processed and bent, the air pump 12 is activated, which delivers gas to the inner cavity of the cylinder 111 through the air pipe 13. This causes the support rod 115 to slide along the inner wall of the cylinder 111 under the pressure of the gas. As the support rod 115 slides, the spring 116 is compressed. Simultaneously, as the support rod 115 drives the connecting rods 118 and 110 to rotate, the contact rod 117, pushed by the connecting rods 118 and 110, causes the connecting rod 114 to rotate 90 degrees, thus achieving the desired rotation of the contact rod 117. The bottom of 7 is positioned and fixed to the top of the main body 7 of the plate. Then, by activating the solenoid valve 112, the solenoid valve 112 will depressurize and discharge the gas in the inner cavity of the cylinder 111. This causes the support rod 115 to drive the contact rod 117, the connecting rod 118, the square plate 119, and the connecting rod 110 to reset under the compression and rebound of the spring 116. Through the same operation, the other movable component of the baffle body 6 can also be positioned, fixed, and reset to the main body 7 of the plate. This effectively avoids the situation where the other end of the main body 7 tilts up and accidentally injures the worker when one end of the plate body 7 is bent.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
