[0002] Hydraulic press, also known as oil press, can be used in forging, pressing, packaging, sheet shaping and other processes. Among the various types of hydraulic presses, gantry hydraulic presses are often used for shaping metal sheets. Gantry hydraulic presses consist of a workbench and a gantry beam. The sheet to be shaped is placed on the workbench, and the hydraulic system is installed at the gantry beam. The purpose of shaping the sheet placed on the workbench is achieved through the lifting of the hydraulic system.

[0003] Specifically, the hydraulic system achieves the purpose of shaping the metal sheet by controlling the lifting and lowering of the hydraulic column. The hydraulic system is composed of components such as a hydraulic pump and an oil cylinder. When working, the hydraulic pump generates pressure and transmits the pressure to the oil cylinder to realize the reciprocating motion of the hydraulic column. When the hydraulic column descends to contact the plate to be shaped, the hydraulic column will rotate to a certain extent due to a certain force, which will cause an error in the measurement of the downward pressure distance of the hydraulic column, and then cause an error in the shaping of the metal sheet. In addition, due to the limitation of the gantry beam, when the metal sheet is a material with a large mass such as carbon steel or stainless steel, it is impossible to place the metal sheet in the center of the workbench by using a crane to lift it, and due to the large mass of the metal sheet, the subsequent position adjustment of the metal sheet is also inconvenient, affecting the shaping effect of the metal sheet.

[0020] Compared with the prior art, the invention has the following beneficial effects: first, the distance measuring device is mounted on the hydraulic body and the bearing is mounted on the hydraulic column, and the guide wire of the distance measuring device is hung on the outer ring of the bearing. When the hydraulic column is pressed down to contact with the metal sheet and rotates, the traction of the guide wire can make the outer ring of the bearing rotate relative to the inner ring to keep the guide wire in an axial state parallel to the hydraulic column, so as to avoid the distance measurement error caused by the rotation of the hydraulic column, thereby effectively improving the shaping accuracy of the metal sheet.

In addition, by making the height of the first baffle plate and the second baffle plate greater than the upper surface height of the material transfer plane, and the upper surface height of the material transfer plane lower than the upper surface height of the workbench, the sliding device can be effectively limited in the process of rolling along the material transfer plane to prevent the sliding device from escaping from the material transfer track.

The driving end of the lifting cylinder is then lowered to make the metal sheet contact with the shaping jig. The overall position of the hydraulic assembly is adjusted at the door frame according to actual needs, and the hydraulic column is pressed down to cooperate with the shaping jig to perform partial or overall shaping on the metal sheet.

[0027] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0028] Ginseng Figures 1 to 4, is a metal sheet hydraulic shaping equipment disclosed by the present invention, through a distance measuring device 423 assembled on a hydraulic body 422 and a bearing 424 assembled on a hydraulic column 421, a guide wire 4231 of the distance measuring device 423 is hung on the outer ring of the bearing 424, when the hydraulic column 421 is pressed down to contact with the metal sheet (not shown) and rotates, the traction effect of the guide wire 4231 can make the outer ring of the bearing 424 rotate relative to the inner ring to keep the guide wire 4231 in a state parallel to the axial direction of the hydraulic column 421, so as to avoid the distance measurement error caused by the rotation of the hydraulic column 421, thereby effectively improving the shaping accuracy of the metal sheet. Furthermore, the material transfer mechanism 2 composed of the material transfer track 22 and the sliding device 21 can be used to relatively easily move and adjust the position of a metal sheet of a larger mass. The metal sheet is placed above a number of sliding devices 21, and the metal sheet is pushed to cause relative rolling between the sliding device 21 and the material transfer track 22, so that the position of the metal sheet to be shaped is pushed to a position close to the bottom of the hydraulic column, and the hydraulic component 42 is moved as a whole along the length direction of the portal frame 41 so that the hydraulic column 421 is directly opposite to the position of the metal sheet to be shaped, and then the hydraulic column 421 is lowered to achieve the purpose of shaping the metal sheet. Compared with the existing gantry hydraulic press, the present invention effectively avoids the problem of distance measurement error caused by the rotation of the hydraulic column 421 when it contacts the metal sheet, which in turn causes error in the shaping of the metal sheet, and effectively reduces the difficulty of adjusting the position of the metal sheet on the workbench 1.

[0029] Ginseng Figures 1 to 4As shown, a specific embodiment of a metal sheet hydraulic shaping device disclosed by the present invention (hereinafter referred to as hydraulic shaping device) includes: a workbench 1 and a hydraulic mechanism 4, the hydraulic mechanism 4 includes a door-shaped frame 41 and a hydraulic assembly 42, a metal sheet (not shown) is placed on the upper surface of the workbench 1, the hydraulic assembly 42 moves along the length direction of the door-shaped frame 41, and the hydraulic assembly 42 moves downward to contact the metal sheet through a hydraulic column 421; the hydraulic assembly 42 also includes a hydraulic body 422, the hydraulic column 421 passes through the bottom end of the hydraulic body 422, and the outer wall of the hydraulic body 422 is equipped with a distance measuring device 423, the distance measuring device 423 has a guide line 4231, and the hydraulic The outer wall of the pressure column 421 is assembled with a bearing 424, and the end of the guide wire 4231 away from the distance measuring device 423 is hung on the outer ring of the bearing 424. The door-type frame 41 is assembled with a digital display 43, and the digital display 43 is electrically connected to the distance measuring device 423 and displays the extended distance of the guide wire 4231; the workbench 1 has a plurality of sets of material moving mechanisms 2, and the material moving mechanisms 2 include a material moving track 22 and a sliding device 21 installed in the material moving track 22. The material moving track 22 is arranged perpendicular to the length direction of the door-type frame 41, and the sliding device 21 is rollingly matched with the material moving track 22. The metal sheet contacts the upper surfaces of several sliding devices and moves along the length direction of the material moving track 22 with the sliding device 21 to approach the door-type frame.

[0030] Ginseng Figure 1 and Figure 2As shown, the outer wall of the hydraulic body 422 is fixedly connected to the locking hoop 4221, the distance measuring device 423 is assembled on the outer wall of the locking hoop 4221, the outer ring of the bearing 424 is fixedly connected to the mounting seat 44, and the mounting seat 44 includes a first connecting block 441, a second connecting block 442 and a hanging ear 443, the first connecting block 441 and the second connecting block 442 are clamped and locked on the upper and lower sides of the outer ring of the bearing 424, the hanging ear 443 is clamped between the first connecting block 441 and the second connecting block 442, and the hanging ear 443 is provided with a through hole 444 for the guide line 4231 to pass through. It should be noted that in this embodiment, the distance measuring device 423 is selected as an ultrasonic distance measuring sensor, and the downward pressing distance of the hydraulic column 421 is obtained by measuring the distance between the hanging ear 443, and the hanging ear 443 is directly assembled at the hydraulic column 421 when the guide line 4231 and the bearing 424 are not provided. When the hydraulic column 421 is pressed down to contact the metal plate and rotates due to the force, the hanging ear 443 rotates together with the hydraulic column 421 and deflects to a certain extent. At this time, the pressing distance of the hanging ear 443 measured by the distance measuring device 423 set as an ultrasonic distance measuring sensor is the oblique distance, rather than the actual longitudinal vertical downward distance of the hanging ear 443 with the hydraulic column 421. That is, at this time, the downward movement distance of the hydraulic column 421 measured by the distance measuring device 423 is greater than the actual pressing distance of the hydraulic column 421. Therefore, it is possible that the actual downward movement distance of the hydraulic column 421 does not reach the measured value, that is, the hydraulic column 421 does not reach the required downward movement distance, thereby affecting the shaping effect of the metal plate.

[0031] In this embodiment, the distance measurement error caused by the rotational deviation of the hydraulic column 421 can be effectively avoided by designing the guide wire 4231 and the bearing 424. Specifically, in this embodiment, the bearing 424 is selected as a roller bearing. The inner ring of the bearing 424 is fixed to the outer wall of the hydraulic column 421 so that the hydraulic column 421 can drive the bearing 424 to rise and fall as a whole. Moreover, when the hydraulic column 421 contacts the metal plate and rotates, due to the design of the guide wire 4231, the guide wire 4231 pulls the outer ring of the bearing 424 and its inner ring to rotate relative to each other under the action of gravity, thereby maintaining the vertical state of the guide wire 4231. Furthermore, since the lug 443 is clamped on the outer ring of the bearing 424 by the first connecting block 441 and the second connecting block 442 and the guide wire 4231 is hooked on the through hole 444 opened in the lug 443, when the bearing 424 moves downward along with the hydraulic column 421, the lug 443 pulls the bottom end of the guide wire 4231 downward to extend the guide wire 4231, and the guide wire 4231 applies traction to the lug 443 to drive the outer ring of the bearing 424 to return to the correct position. It can be known from the above design that the traction force of the guide wire 4231 can drive the lug 443 and the outer ring of the bearing 424 to return to the correct position. At this time, the guide wire 4231 is in a state parallel to the axis of the hydraulic column 421. Therefore, it can be obtained that the lug 443 is located directly below the distance measuring device 423. At this time, the downward movement distance of the hydraulic column 421 measured by the distance measuring device 423 is a more accurate vertical distance, and is equivalent to the elongated length of the guide wire 4231. The digital display 424 electrically connected to the distance measuring device 423 directly displays the elongated length of the guide wire 4231, which can be regarded as the accurate downward movement distance of the hydraulic column 421.

[0032] Furthermore, after the hydraulic column 421 completes a local shaping of the metal sheet, the hydraulic column 421 rises, and at this time the guide wire 4231 is shortened by a certain distance as the lug 443 rises. At this time, the value displayed by the digital display 424 is the shortening value of the guide wire 4231. Through the aforementioned scheme, the lifting distance of the hydraulic column 421 can be accurately fed back simply and intuitively, thereby achieving the purpose of more accurate shaping of the metal sheet. It should be noted that the guide wire 4231 is wound on a winding device that is commonly used in the prior art and can realize automatic retraction of the wire, which will not be described in detail here. Furthermore, in this embodiment, the displayed value of the digital display 424 can be manually reset to zero to avoid secondary overpressure of the metal sheet.

[0033] Ginseng Figure 1 and Figure 3As shown, the material moving track 23 includes a material moving plane 221, a first extension portion 222 and a second extension portion 223, the first extension portion 222 and the second extension portion 223 are vertically distributed on both sides of the length direction of the workbench 1, one end of the material moving plane 221 is located in the first extension portion 222, and the other end of the material moving plane 221 is located in the second extension portion 223 after vertically passing through the workbench 1. The upper surface of the material moving plane 221 is lower than the upper surface of the workbench 1, the first extension portion 222 and the second extension portion 223 respectively have a first baffle 2221 and a second baffle 2222, the material moving plane 221 is vertically arranged between the first baffle 2221 and the second baffle 2222, and the top surfaces of the first baffle 2221 and the second baffle 2222 are higher than the upper surface of the material moving plane 221. The first extension portion 222 and the second extension portion 223 also have a support leg 23, a bottom plate 24 is fixedly connected between the bottom walls of the first baffle plate 2221 and the second baffle plate 2222, and the top of the support leg 23 is connected to the bottom plate 24; the first baffle plate 2221, the second baffle plate 2222 and the material transfer plane 221 located between the first baffle plate 2221 and the second baffle plate 2222 are all detachably connected to the workbench 1.

[0034] In this embodiment, the material transfer track 22 is composed of a material transfer plane 221, a first extension portion 222 and a second extension portion 223, wherein the sliding device 21 is placed on the material transfer plane 221 and rolls relative to the material transfer plane 221. The setting of the first extension portion 222 and the second extension portion 223 realizes extending a larger area on the basis of the width of the workbench itself 1 as the loading area and unloading area of ​​the workbench 1. When loading, a number of sliding devices 21 are selectively moved to the material transfer plane 221 of the first extension portion 222 or the second extension portion 223 according to the position of the metal sheet, and then the metal sheet is placed above the several sliding devices 21. When pushing the metal sheet, the rolling cooperation between the sliding device 21 and the material transfer plane 221 can save effort to move the metal sheet to the workbench. Furthermore, since the height of the first baffle 2221 and the second baffle 2222 is greater than the upper surface height of the material transfer plane 221 and the upper surface height of the material transfer plane 221 is lower than the upper surface height of the workbench 1, the sliding device 21 can be effectively limited during rolling along the material transfer plane 221 to prevent the sliding device 21 from detaching from the material transfer track 22.

[0035] Ginseng Figure 1In the embodiment shown, the material transfer track 22 composed of the material transfer plane 221, the first extension part 222 and the second extension part 223 is set to three groups in total. Taking the first extension part 222 as the loading end, for example, the plurality of sliding devices 21 distributed in the three groups of material transfer tracks 22 are moved to the first extension part 222 and the material transfer plane 221 of the workbench 1 close to the first extension part 222, and the metal sheet is placed on the plurality of sliding devices 21. The plurality of sliding devices 21 can support the metal sheet uniformly and stably. The metal sheet is pushed toward the workbench 1, and the plurality of sliding devices 21 roll relative to the material transfer plane 221 until the metal sheet is completely moved to the workbench 1, and the stop position of the metal sheet on the workbench 1 can be selected according to the part of the metal sheet that actually needs to be shaped. Furthermore, the support leg 23 can effectively support the first extension portion 222 and the second extension portion 222, and the first baffle 2221 and the second baffle 2222 and the material transfer plane 221 between the first baffle 2221 and the second baffle 2222 can be detachably matched with the workbench 1, so that the first extension portion 222 and the second extension portion 223 can be removed when they are not needed.

[0036] Ginseng Figure 1 and Figure 3As shown, the sliding device 21 includes a pulley 211 and a sliding seat 212. The sliding seat 212 includes a first plate 213 and a second plate 214 that are parallel to each other. Two pulleys 211 are arranged in front and back, and the two ends of the rotating shafts of the two pulleys 211 are respectively connected to the first plate 213 and the second plate 214; the two pulleys 211 are rollingly matched with the material transfer plane 221, and there is a gap between the lower surface of the first plate 213 and the second plate 214 and the first baffle 2221, the second baffle 2222 and the upper surface of the workbench 1. The top surfaces of the first plate 213 and the second plate 214 are fixedly connected to the first protection pad 215. Through the design of the first protection pad 215, when the metal sheet is placed on the sliding device 21, the first protection pad 215 contacts the lower surface of the metal sheet. In this embodiment, the first protection pad 215 is selected as a rubber pad, which can effectively protect the surface of the metal sheet. When the sliding device 21 rolls on the material transfer plane 221, the first baffle 2221, the second baffle 2222 and the workbench 1 are in contact with the left and right sides of the pulley 211 to ensure that the sliding device 21 as a whole can move along the length direction of the material transfer plane 221 without being separated from the material transfer track 22. Further, in this embodiment, the sliding device 21 is limited to the left and right only by the height of the first baffle 2221, the second baffle 2222 and the workbench 1, and there is no longitudinal limit on the sliding device 21, so an upward force can be applied to the sliding device 21 to move it out of the material transfer track 22. The pulley 211 of the sliding device 21 rolls with the material transfer plane 221, so that a metal sheet with a large mass can be moved to the workbench 1 more easily through the sliding device 21, and the position of the metal sheet on the workbench 1 can be adjusted as needed, further reducing the difficulty of the metal sheet shaping process.

[0037] Ginseng Figure 1 and Figure 4 As shown, the workbench 1 is evenly distributed with a plurality of lifting devices 11, and the lifting devices 11 include a lifting cylinder 111 and a lifting plate 112. The lifting cylinder 111 is fixed to the lower surface of the workbench 1, and the driving end of the lifting cylinder 111 passes through the workbench 1 and is connected to the lower surface of the lifting plate 112. The upper surface of the lifting plate 111 is covered with a second protective pad 113. It should be noted that the workbench 1 is evenly distributed with a plurality of reserved holes 12 for the driving end of the lifting cylinder 111 to pass through. Figure 1 and Figure 4 In the state shown, no lifting cylinders 111 are installed below the plurality of reserved holes 12. The hydraulic shaping device further comprises: an oil pump 5, which is connected to the plurality of lifting cylinders 111 via an oil delivery pipeline 51.

[0038] After the sliding device 21 moves the metal sheet to the appropriate position of the workbench 1, the driving end of the lifting cylinder 111 constituting the lifting device 11 is raised, and the lifting plate 1112 connected to the top of the driving end of the lifting cylinder 111 is raised to a state of supporting the lower surface of the metal sheet. At this time, the sliding device 21 can be removed from the material transfer plane 221, and a shaping jig (not shown) is placed between the workbench 1 and the metal sheet. Then, the driving end of the lifting cylinder 111 is lowered to make the metal sheet contact with the shaping jig. According to actual needs, the overall position of the hydraulic assembly 42 is adjusted at the door frame 41, and then the hydraulic column 421 is pressed down to cooperate with the shaping jig to perform partial or overall shaping on the metal sheet. It should be noted that in this embodiment, the oil pump 5 and the oil pipeline 51 are synchronously connected to a plurality of lifting cylinders 111, and the motor of the oil pump 5 is started by controlling the remote control so that the driving ends of the plurality of lifting cylinders 111 are simultaneously raised to lift the metal plates, thereby achieving the purpose of unified control of the plurality of lifting cylinders 111.

[0039] Ginseng Figure 1 As shown, the length direction of the portal frame 41 is consistent with the length direction of the workbench 1, and the two supports of the portal frame 41 are respectively fixed to the upper surface of the workbench 1. A driving chain (not marked) is arranged on the top surface of the portal frame 41 along the length direction, and the hydraulic body 422 is connected to the driving chain to achieve the purpose of driving the hydraulic assembly 42 to move along the length direction of the portal frame 41 as a whole.
