DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] When implementing: Figure 1-6As shown, a bending device for processing sheet metal parts of machine tools comprises a workbench 1, an adjustment support box 2 and a positioning support plate 3: the top outer wall of the workbench 1 is provided with an adjustment support box 2, the side outer wall of the adjustment support box 2 is slidably mounted with a positioning support plate 3, a bending adjustment mechanism 4 is provided inside the adjustment support box 2, a bending control mechanism 5 is provided above the positioning support plate 3, a portable disassembly mechanism 6 is provided on the side of the bending control mechanism 5, and the bending adjustment mechanism 4 comprises a control motor 41, a reciprocating screw rod 42, an auxiliary Auxiliary support shaft 43 and control block 44, the top outer wall of the middle position of the adjustment support box 2 is provided with a control motor 41, the control motor 41 is connected to the top outer wall of the reciprocating screw 42, the bottom outer wall of the reciprocating screw 42 is connected to the top outer wall of the auxiliary support shaft 43, the bottom outer wall of the auxiliary support shaft 43 is rotatably installed with the bottom inner wall of the adjustment support box 2, the outside of the reciprocating screw 42 is provided with a control block 44, and the outer walls on both sides of the control block 44 are symmetrically provided with protrusions, and the protrusions slide with the side inner walls of the adjustment support box 2. The control block 44 is symmetrically provided with a control panel on the side outer wall, and the side outer wall of the control panel is connected to the side outer wall of the positioning support plate 3; when the supporting height of the positioning support plate 3 needs to be controlled, the control motor 41 needs to be turned on first. When the control motor 41 is turned on, it will automatically drive the reciprocating screw 42 to rotate and then drive the auxiliary support shaft 43 to rotate. The setting of the auxiliary support shaft 43 here plays an auxiliary supporting effect on the reciprocating screw 42. When the reciprocating screw 42 rotates, it will automatically drive the control block 44 to move. Here, due to the convex blocks set on both sides of the control block 44 and the setting of sliding installation on the side inner wall of the adjustment support box 2, the reciprocating screw 42 will only drive the control block 44 to realize the sliding trajectory movement in the vertical direction when rotating. Then, the movement of the control block 44 will automatically drive the control panel to move and then drive the positioning support plate 3 to move. When the positioning support plate 3 moves to the appropriate position, the control motor 41 can be turned off. It is noted here that the control motor 41 has a self-locking function, and the positioning support plate 3 can still maintain its position unchanged after being turned off.
[0025] The bending control mechanism 5 includes a hydraulic cylinder 51, a mounting plate 52 and an upper mold 53. The hydraulic cylinder 51 is installed on the top outer wall of the positioning support plate 3, and the output end of the hydraulic cylinder 51 is connected to the top outer wall of the mounting plate 52. The mounting plate 52 is arranged below the positioning support plate 3, and the upper mold 53 is installed on the bottom outer wall of the mounting plate 52. When the control device needs to be operated to bend the sheet metal parts of the machine tool, it is first necessary to adjust the position of the sheet metal parts of the machine tool to be bent and place them above the lower mold 71, and then turn on the hydraulic cylinder 51. When the hydraulic cylinder 51 is turned on, its output end will automatically extend and drive the mounting plate 52 to move downward. Then, the downward movement of the mounting plate 52 will automatically drive the upper mold 53 to move and then bend the sheet metal parts of the machine tool.
[0026] The portable disassembly and replacement mechanism 6 includes a contact support plate 61 and a limiting T-shaped strip 62. The top outer wall of the upper mold 53 located at the edge position is provided with a contact support plate 61, and the side outer wall of the contact support plate 61 is provided with a limiting T-shaped strip 62, and the limiting T-shaped strip 62 is connected to the top outer wall of the upper mold 53. The side outer wall of the contact support plate 61 is symmetrically penetrated with a first threaded groove 63, and the side outer wall of the mounting plate 52 is provided with a contact mounting groove 64. The side outer wall of the mounting plate 52 located at the contact mounting groove 64 is provided with a limiting T-shaped groove 65, and the side outer wall of the mounting plate 52 located at the limiting T-shaped groove 65 is symmetrically provided with a second threaded hole 66, the opening diameter of the first threaded groove 63 is equal to the opening diameter of the second threaded hole 66, and the first threaded groove 63 and the second threaded hole 66 are threadedly installed with the positioning bolt 67; when it is needed according to the machine When the bending requirements of bed sheet metal parts require the replacement of a suitable upper mold 53, it is first necessary to unscrew the positioning bolt 67 from the inside of the resistance support plate 61, and then the resistance support plate 61 changes from a locked state to an active state, and then pull the resistance support plate 61 toward the horizontal side to pull the upper mold 53 out from the inside of the mounting plate 52. When installing a new upper mold 53, it is first necessary to adjust the upper mold 53 to a suitable position and push the limiting T-shaped bar 62 into the inside of the limiting T-shaped slot 65. When the limiting T-shaped bar 62 moves to the bottom end of the limiting T-shaped slot 65, the resistance support plate 61 is just stuck in the inside of the resistance mounting slot 64. At the same time, the first threaded groove 63 and the second threaded hole 66 are in a corresponding state of overlap. Then, the positioning bolt 67 is passed through the first threaded groove 63 and screwed into the inside of the second threaded hole 66 at the corresponding position to complete the installation of the new upper mold 53.
[0027] A lower mold 71 is arranged above the workbench 1, and two groups of support blocks 72 are symmetrically arranged on both sides of the lower mold 71. The support blocks 72 are connected to the top outer wall of the workbench 1, and the side outer walls of the support blocks 72 are provided with limit slots 73. The support blocks 72 are located between the top inner wall and the bottom inner wall of the limit slot 73 and are connected with a positioning shaft 74. The side outer wall of the lower mold 71 at the bottom is symmetrically provided with two groups of limit blocks 75. The limit blocks 75 are slidably installed between the limit slots 73, and the limit blocks 75 are slidably installed on the outside of the positioning shaft 74. A support spring 76 is connected between the bottom outer wall of the limit block 75 and the bottom inner wall of the limit slot 73, and the support spring 76 is sleeved on the outside of the positioning shaft 74; when the above-mentioned bending control mechanism 5 bends the machine tool sheet metal parts so that the upper mold 53 contacts the machine tool sheet metal parts, the machine tool sheet metal parts automatically move downward due to the extrusion force and drive the lower mold 71 to move downward. When the lower mold 71 moves downward, it will automatically drive the limit block 75 to slide inside the limit slot 73. At this time, the limit block 75 slides on the outside of the positioning shaft 74 and synchronously squeezes the support spring 76 to contract. At the same time, the support spring 76 automatically generates a reaction force under the extrusion to support the limit block 75. In this way, the above process can achieve the effect of buffer support for the bending of machine tool sheet metal parts.
[0028] When the utility model is in use, it is first necessary to adjust the positioning support plate 3 to a suitable support height according to the bending needs of the sheet metal parts of the machine tool. At this time, it is first necessary to turn on the control motor 41. When the control motor 41 is turned on, it will automatically drive the reciprocating screw 42 to rotate and then drive the auxiliary support shaft 43 to rotate. The setting of the auxiliary support shaft 43 here has an auxiliary supporting effect on the reciprocating screw 42. When the reciprocating screw 42 rotates, it will automatically drive the control block 44 to move. Here, due to the setting of the convex blocks set on both sides of the control block 44 and the sliding installation of the inner wall of the side of the adjustment support box 2, the reciprocating screw 42 will only drive the control block 44 to realize the sliding trajectory movement in the vertical direction when rotating. Subsequently, the movement of the control block 44 will automatically drive the control plate to move and then drive the positioning support plate 3 to move. When the positioning support plate 3 moves to the appropriate position, the control motor 41 can be turned off. It is noted here that the control motor 41 has a self-locking function. After being turned off, the positioning support plate 3 can still maintain its position unchanged after moving.
[0029] When the control device needs to be operated to bend the sheet metal parts of the machine tool, at this time, it is necessary to first adjust the position of the sheet metal parts of the machine tool to be bent and place them above the lower mold 71, and then turn on the hydraulic cylinder 51. When the hydraulic cylinder 51 is turned on, its output end will automatically extend and drive the mounting plate 52 to move downward. Then, the mounting plate 52 moves downward and automatically drives the upper mold 53 to move and then bend the sheet metal parts of the machine tool; when the above-mentioned bending control mechanism 5 bends the sheet metal parts of the machine tool so that the upper mold 53 contacts the sheet metal parts of the machine tool, the sheet metal parts of the machine tool are automatically moved downward by the extrusion force and drive the lower mold 71 to move downward. When the lower mold 71 moves downward, it will automatically drive the limit card block 75 to slide inside the limit card slot 73. At this time, the limit card block 75 slides outside the positioning shaft 74 and synchronously squeezes the support spring 76 to contract. At the same time, the support spring 76 is squeezed and automatically generates a reaction force to support the limit card block 75, so that the above process can achieve the effect of buffer support for the bending of sheet metal parts of the machine tool;
[0030] When it is necessary to replace a suitable upper mold 53 according to the bending requirements of the sheet metal parts of the machine tool, it is first necessary to unscrew the positioning bolt 67 from the inside of the resistance support plate 61, and then the resistance support plate 61 changes from a locked state to an active state, and then the resistance support plate 61 is pulled horizontally to the side to pull the upper mold 53 out from the inside of the mounting plate 52. When installing a new upper mold 53, it is first necessary to adjust the upper mold 53 to a suitable position and push the limiting T-shaped bar 62 into the inside of the limiting T-shaped slot 65. When the limiting T-shaped bar 62 moves to the bottom end of the limiting T-shaped slot 65, the resistance support plate 61 is just stuck in the inside of the resistance mounting slot 64. At the same time, the first threaded groove 63 and the second threaded hole 66 are in a corresponding state of overlap. Then, the positioning bolt 67 is passed through the first threaded groove 63 and screwed into the inside of the second threaded hole 66 at the corresponding position to complete the installation of the new upper mold 53.
[0031] It is noted here that the above-mentioned hydraulic cylinder 51 can be operated using existing hydraulic drive technology, and the control motor 41 is powered by existing technology. Whether it is powered by a power supply unit or an external wire, it belongs to the existing conventional technical operation means and will not be described in detail here.
[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
