Description

Technical Field

[0001] The present application relates to the field of plate processing, and in particular to a fixed plate bending device. Background Art

[0002] A bending machine is a machine that uses a mold to bend cold metal sheets into workpieces of various geometric cross-sectional shapes. It is a sheet forming machine designed for cold rolled sheet metal processing. It has been widely used in sheet metal bending processing in the machinery industry. The bending structure inside the bending machine is the key to determining the bending quality and efficiency.

[0003] At present, mechanical equipment in various industries requires some fixed plates that need to be bent. When the bending machine bends the workpiece, the workpiece to be bent is placed on the lower die, and the hydraulic cylinder drives the protrusion on the upper die to offset the groove of the lower die to complete the bending. However, some workpieces are not easy to remove after bending, which affects work efficiency, and the lower die is generally fixed and installed by multiple bolts, which is troublesome to disassemble and replace. Utility Model Content

[0011] In the above implementation process, a first fixed frame, a first spring and a limiting ring are set, and the limiting ring is pushed by the elastic action of the first spring. The limiting ring pushes the limiting rod, so that the top end of the limiting rod remains through the top of the workbench, thereby abutting and limiting the lower mold, and fixing the lower mold in the groove plate.

[0012] In a specific implementation manner, a slope is provided on the top of the limiting rod, and a pull rod is fixedly connected to the bottom end of the limiting rod.

[0013] In the above implementation process, by setting the inclined surface, when replacing and installing the lower mold, the inclined surface can be directly squeezed to push the limiting rod downward, so that the lower mold can pass over the limiting rod.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0030] See also Figure 1-Figure 5 The present application provides a fixed plate bending device including a fixing component 100 and a pushing component 200 .

[0031] See also Figure 1 , 2 , 3 and 4, the fixing assembly 100 includes a workbench 110, a slot plate 120, a lower mold 130, a limiting rod 140, a first elastic member 150 and a pressing member 170, the slot plate 120 is fixedly connected to the top of the workbench 110, the lower mold 130 is slidably inserted in the slot plate 120, the limiting rod 140 slides through the workbench 110, the first elastic member 150 is arranged between the limiting rod 140 and the workbench 110, and the pressing member 170 is arranged on the top of the workbench 110.

[0032] The lower mold 130 is in a convex shape, and the lower mold 130 and the groove plate 120 are matched. The convex shape of the lower mold 130 can play a good role in limiting and fixing the lower mold 130.

[0033] Specifically, the first elastic member 150 includes a first fixed frame 151, a first spring 152 and a limiting ring 153. The first fixed frame 151 is fixedly connected to the bottom of the workbench 110. The limiting rod 140 slides through the first fixed frame 151. The limiting ring 153 is fixedly sleeved on the outside of the limiting rod 140. The first spring 152 is sleeved on the outside of the limiting rod 140, and the first spring 152 abuts against the first fixed frame 151 and the limiting rod 140. By setting the first fixed frame 151, the first spring 152 and the limiting ring 153, the limiting ring 153 is pushed by the elastic action of the first spring 152, and the limiting ring 153 pushes the limiting rod 140, so that the top end of the limiting rod 140 remains through the top of the workbench 110, thereby abutting and limiting the lower mold 130, and fixing the lower mold 130 in the groove plate 120.

[0034] In a specific implementation scheme, a slope 141 is provided on the top of the limiting rod 140, and a pull rod is fixedly connected to the bottom end of the limiting rod 140. By providing the slope 141, when replacing and installing the lower mold 130, the slope 141 can be directly squeezed to push the limiting rod 140 downward, so that the lower mold 130 can pass over the limiting rod 140.

[0035] In this embodiment, the lower pressure piece 170 includes a vertical plate 171, a hydraulic cylinder 172 and an upper mold 173. The vertical plate 171 is fixedly connected to the top of the workbench 110, the hydraulic cylinder 172 is installed at the end of the vertical plate 171, and the upper mold 173 is installed at the output end of the hydraulic cylinder 172. By setting the vertical plate 171, the hydraulic cylinder 172 and the upper mold 173, the hydraulic cylinder 172 is started to push the upper mold 173, and the upper mold 173 moves down close to the lower mold 130 to bend the fixed plate workpiece.

[0036] In a specific implementation, a connecting ring 1731 is provided on the top of the upper mold 173, and the connecting ring 1731 is connected to the output end of the hydraulic cylinder 172 by bolts. The single bolt connection is relatively simple to assemble and disassemble.

[0037] See also Figure 1 , 2 5. The pusher assembly 200 includes a pusher slide bar 210 and a second elastic member 230. The second elastic member 230 is disposed at the bottom of the workbench 110. The pusher slide bar 210 slides through the workbench 110 and the lower mold 130 and is threadedly connected to the second elastic member 230.

[0038] Among them, the second elastic member 230 includes a second fixing frame 231, a second spring 232 and an internally threaded tube 233. The second fixing frame 231 is fixedly connected to the bottom of the workbench 110, and the internally threaded tube 233 slides through the second fixing frame 231. The second spring 232 is arranged between the internally threaded tube 233 and the second fixing frame 231. The limiting plug rod 140 is threadedly connected to the internally threaded tube 233. By arranging the second fixing frame 231, the second spring 232 and the internally threaded tube 233, when the workpiece is bent, the fixed plate workpiece will also press down the push slide 210 when being bent, and the push slide 210 squeezes the second spring 232. When the workpiece is bent, the elastic recovery effect of the second spring 232 is used to push the internally threaded tube 233, so that the internally threaded tube 233 pushes the push slide 210 to move up, and the push slide 210 pushes the workpiece out of the lower mold 130 for easy material removal. When disassembling and assembling the lower mold 130, the push slide 210 can be rotated to remove it.

[0039] In a specific implementation, the internal threaded tube 233 is rectangular, and an abutment ring is provided on the outer side of the internal threaded tube 233 to abut against the second spring 232. The rectangular design of the internal threaded tube 233 prevents the internal threaded tube 233 from rotating and guides it to move up and down in a straight line.

[0040] The working principle of the fixed plate bending device is as follows: when disassembling and replacing the lower mold 130, first rotate and remove the push slide bar 210, pull the lower mold 130 to drive the limit plug rod 140 to move, and the limit plug rod 140 drives the limit ring 153 to move and squeeze the first spring 152 to pull the top of the limit plug rod 140 into the workbench 110, so that the lower mold 130 can be slid out of the groove plate 120 for replacement. After replacement, the limit ring 153 is pushed by the elastic action of the first spring 152, and the limit ring 153 pushes the limit plug rod 140, so that the top of the limit plug rod 140 keeps passing through the top of the workbench 110, thereby abutting and limiting the lower mold 130, fixing the lower mold 130 in the groove plate 120, avoiding The installation method of multiple bolts improves efficiency. Finally, the push slide 210 is passed through the hole of the lower mold 130 and the workbench 110, and is threaded into the workbench 110. During use, the hydraulic cylinder 172 pushes the upper mold 173 downward to cooperate with the lower mold 130 to bend the fixed plate workpiece. During the bending process, the fixed plate workpiece pushes the push slide 210, and the push slide 210 pushes the internal threaded tube 233 to squeeze the second spring 232. After bending, the hydraulic cylinder 172 drives the upper mold 173 back to its original position. At the same time, the second spring 232 elastically recovers to push the internal threaded tube 233 and the push slide 210. The push slide 210 moves upward to push the workpiece out of the lower mold 130, greatly improving the loading and unloading efficiency.

[0041] It should be noted that the specific model and specifications of the hydraulic cylinder 172 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0042] The power supply and principle of the hydraulic cylinder 172 are clear to those skilled in the art and will not be described in detail here.

[0043] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
