Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of blanking die accessories, in particular to a blanking die supporting mechanism. Background Art
[0002] The blanking die is a continuous production die with the advantages of high production efficiency, high material utilization rate, good surface quality of blanked parts, etc., while greatly reducing the workload of manpower. In the blanking die, the supporting mechanism is an important component, which is mainly used to avoid wear between the sheet and the lower mold during feeding, and to avoid tilting, grooves, bending of the sheet.
[0003] The existing blanking die supporting mechanism mainly supports the blanking parts by the elasticity of the bracket itself and the roller, or drives the bracket to move up or rotate upward and supports the blanking parts by the roller through elastic elements such as springs and torsion springs.
[0004] The existing blanking die support mechanism usually adopts an integrated structure or a bolt-type disassembly structure. However, after being used for a long time, the support structure will inevitably experience the phenomenon of reduced elasticity, wear and looseness, etc., making it difficult to quickly and individually replace a certain component. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide a blanking die supporting mechanism to solve the technical problems mentioned in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a blanking die supporting mechanism, comprising a mounting plate, a guide frame fixed on the top of the mounting plate, a spring connected to the middle of the top of the mounting plate, and a bracket connected to the top of the spring, a slot is opened on the upper side of one side of the bracket, and a roller is connected inside the slot, a slip ring is sleeved on the outside of the roller, a movable plate is arranged below the outer surface of the bracket, and a limiting block is fixed on the outer surface of the movable plate, and a limiting groove is opened below the outer surface of the guide frame.
[0007] By adopting the above technical solution, when it is necessary to replace the roller separately, it is only necessary to push the roller towards the slot with force to make the roller fall off, thereby completing the disassembly. When installing, it is only necessary to put the roller into the slot and then press it into the bracket with force. The roller can be held by the elasticity of the bracket itself to prevent the roller from falling off. When it is necessary to replace the spring or the bracket separately, it is only necessary to press the limit block with force to make the movable plate bend and deform, so that the limit block is moved out of the limit groove to end the limitation of the bracket. After that, it is only necessary to pull the bracket upward to replace the bracket or the spring. During installation, first place the spring in the middle of the top of the mounting plate, then press the limit block to make the movable plate bend, and then insert the bracket into the guide frame. When the limit block corresponds to the limit groove, the movable plate restores its original straight shape through its own elasticity, so that the limit block enters the limit groove to prevent the bracket from falling off from the guide frame when sliding upward.
[0008] Furthermore, the bracket is slidably connected to the guide frame.
[0009] By adopting the above technical solution, during processing, the blanking machine applies pressure to the blank, so that the blank moves down and fits the lower mold. At the same time, the roller is affected by the pressure of the blank and drives the bracket to move down. The spring is compressed while the bracket moves down. After the blanking is completed, the spring drives the roller to move up through the bracket, thereby lifting the blank. At this time, the blank can be transported through the feeding structure.
[0010] Furthermore, the bracket, movable plate and limit block are all made of spring steel.
[0011] By adopting the above technical solution, the bracket, movable plate and limit block are formed by cutting from a piece of spring steel blank. The integrated structure has high strength and stable connection. The bracket can hold the roller through its own elasticity to prevent the roller from falling off, and the movable plate can restore its original straight shape through its own elasticity, so that the limit block enters the limit groove to prevent the bracket from falling off from the guide frame when sliding upward.
[0012] Furthermore, the limiting block abuts against the limiting groove, and the height of the limiting groove is greater than the height of the limiting block.
[0013] By adopting the above technical solution, when the bracket slides upward, the limit block abuts against the limit groove to prevent the bracket from falling off the guide frame. The height of the limit groove is greater than the height of the limit block to avoid affecting the upward and downward sliding of the limit block.
[0014] Furthermore, the roller abuts against the slot, and the roller is rotatably connected to the bracket.
[0015] By adopting the above technical solution, during the conveying process, the blanks are lifted up by the rollers, thereby avoiding the blanks from contacting and abrading with the lower mold, and the rolling of the rollers reduces the abrasion between the rollers and the blanks.
[0016] Furthermore, two slip rings are provided, and both slip rings are made of Teflon material.
[0017] By adopting the above technical solution, the Teflon slip ring has a self-lubricating effect, which can reduce the friction between the roller and the bracket, thereby avoiding wear.
[0018] Furthermore, four mounting holes are respectively opened on both sides of the top of the mounting plate, and the four mounting holes are distributed in a rectangular array.
[0019] By adopting the above technical solution, the staff will pass the bolts through the mounting holes to install the mounting plate into the blanking die, and the disassembly and assembly operations are common and not difficult to perform.
[0020] Furthermore, a sliding sleeve is fixed inside the guide frame, and the sliding sleeve is made of Teflon material.
[0021] By adopting the above technical solution, the Teflon sleeve has self-lubricating property during the up and down movement of the bracket, thereby reducing the friction between the bracket and the guide frame, thereby avoiding wear between the bracket and the guide frame.
[0022] In summary, the utility model mainly has the following beneficial effects:
[0023] 1. The utility model is provided with slots, rollers and slip rings. When the roller needs to be replaced separately, the roller can be removed by pushing the roller toward the slot. When installing, the roller can be held by the slot and then pressed into the bracket. The elasticity of the bracket can prevent the roller from falling off. At the same time, the setting of the slip ring can reduce the friction and wear between the roller and the bracket when the roller rolls. It is convenient to replace the roller, and the structure is simple and the operation is convenient.
[0024] 2. The utility model provides a guide frame, a spring, a bracket, a movable plate, a limit block and a limit groove. When it is necessary to replace the spring or the bracket separately, it is only necessary to press the limit block hard to make the movable plate bend and deform, so that the limit block is moved out of the limit groove to end the limitation of the bracket. After that, it is only necessary to pull the bracket upward to replace the bracket or the spring. During installation, the spring is first placed in the middle of the top of the mounting plate, and then the limit block is pressed to bend the movable plate. At this time, the bracket is inserted into the guide frame. When the limit block corresponds to the limit groove, the movable plate restores its original straight shape through its own elasticity, so that the limit block enters the limit groove, and prevents the bracket from falling off the guide frame when sliding upward. It is convenient to replace the spring and the bracket, and the structure is simple and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0031] The following describes an embodiment of the utility model based on its overall structure.
[0032] Embodiment 1:
[0033] A blanking die support mechanism, such as Figure 1-Figure 4 As shown, it includes a mounting plate 1, a guide frame 3 is fixed on the top of the mounting plate 1, a spring 5 is connected in the middle of the top of the mounting plate 1, a bracket 6 is connected to the top of the spring 5, the bracket 6 is slidably connected to the guide frame 3, the spring 5 drives the roller 11 to move upward through the bracket 6, so as to lift the blanking part, at this time, the blanking part can be conveyed through the feeding structure to facilitate continuous production, and during the conveying process of the blanking part, the roller 11 lifts the blanking part, thereby avoiding the blanking part from contacting with the lower mold and causing wear;
[0034] A slot 10 is provided on the upper side of the bracket 6, and a roller 11 is connected to the inside of the slot 10. The roller 11 abuts against the slot 10. When the roller 11 needs to be replaced separately, the roller 11 only needs to be pushed towards the slot 10 to make the roller 11 fall off, thereby completing the disassembly. When installing, the roller 11 only needs to be put into the slot 10 and then pressed into the bracket 6. The roller 11 is rotatably connected to the bracket 6, and a slip ring 12 is sleeved on the outside of the roller 11. Two slip rings 12 are provided, and the two slip rings 12 are made of Teflon material. Since the roller 11 lifts the blanking part, the blanking part is prevented from contacting with the lower mold and causing wear. At the same time, the roller 11 rolls to reduce the wear between the roller 11 and the blanking part, and the slip ring 12 made of Teflon has a self-lubricating effect, which can reduce the friction between the roller 11 and the bracket 6, thereby avoiding wear.
[0035] A movable plate 7 is arranged below the outer surface of the bracket 6, and a limiting block 8 is fixed on the outer surface of the movable plate 7. When the spring 5 or the bracket 6 needs to be replaced separately, the limiting block 8 only needs to be pressed hard to make the movable plate 7 bend and deform, so that the limiting block 8 is moved out of the limiting groove 9 to end the limiting of the bracket 6; the bracket 6, the movable plate 7 and the limiting block 8 are all made of spring steel material, and the bracket 6, the movable plate 7 and the limiting block 8 are formed by cutting and processing a piece of spring steel blank. The integrated structure has high strength and stable connection; a limiting groove 9 is opened below the outer surface of the guide frame 3, and the limiting block 8 abuts against the limiting groove 9. The height of the limiting groove 9 is greater than the height of the limiting block 8. The limiting block 8 enters the limiting groove 9 to prevent the bracket 6 from falling off from the guide frame 3 when sliding upward.
[0036] See also Figure 1-Figure 4In the above embodiment, four mounting holes 2 are respectively opened on both sides of the top of the mounting plate 1, and the four mounting holes 2 are distributed in a rectangular array. The staff passes the bolts through the mounting holes 2 to install the mounting plate 1 into the blanking die.
[0037] Embodiment 2:
[0038] On the basis of the above-mentioned embodiment 1, in order to reduce the wear of the guide frame 3 and the bracket 6, the following settings are now adopted.
[0039] See also Figure 1-Figure 4 In the above embodiment, a sliding sleeve 4 is fixed inside the guide frame 3, and the sliding sleeve 4 is made of Teflon material. During the up and down movement of the bracket 6, the sliding sleeve 4 made of Teflon material has self-lubricating properties, thereby reducing the friction between the bracket 6 and the guide frame 3, thereby avoiding wear between the bracket 6 and the guide frame 3.
[0040] The implementation principle of the utility model is as follows: first, during processing, the blanking machine applies pressure to the blanking piece, so that the blanking piece moves down and fits with the lower mold. At the same time, the roller 11 is affected by the pressure of the blanking piece and drives the bracket 6 to move down. The bracket 6 compresses the spring 5 while moving down. After the blanking is completed, the spring 5 drives the roller 11 to move up through the bracket 6, thereby lifting the blanking piece. At this time, the blanking piece can be transported through the feeding structure to facilitate continuous production. During the transportation of the blanking piece, the roller 11 lifts the blanking piece, thereby avoiding the blanking piece from contacting with the lower mold and causing wear. During the up and down movement of the bracket 6, the sliding sleeve 4 made of Teflon has self-lubricating properties, thereby reducing the friction between the bracket 6 and the guide frame 3, thereby avoiding wear between the bracket 6 and the guide frame 3. At the same time, the roller 11 rolls to reduce the wear between the roller 11 and the blanking piece, and the slip ring 12 made of Teflon has a self-lubricating effect, which can reduce the friction between the roller 11 and the bracket 6, thereby avoiding wear.
[0041] When it is necessary to replace the roller 11 separately, it is only necessary to push the roller 11 towards the slot 10 with force to make the roller 11 fall off, thereby completing the disassembly. When installing, it is only necessary to put the roller 11 into the slot 10 and then press it into the bracket 6 with force. The roller 11 can be held by the elasticity of the bracket 6 to prevent the roller 11 from falling off; when it is necessary to replace the spring 5 or the bracket 6 separately, it is only necessary to press the limit block 8 with force to make the movable plate 7 bend and deform, so that the limit block 8 is moved out of the limit groove 9 to end the limit of the bracket 6, and then it is only necessary to pull out the bracket 6 upward to replace the bracket 6 or the spring 5. During installation, the spring 5 is first placed in the middle of the top of the mounting plate 1, and then the limit block 8 is pressed to make the movable plate 7 bend. At this time, the bracket 6 is inserted into the guide frame 3. When the limit block 8 corresponds to the limit groove 9, the movable plate 7 restores its original straight shape through its own elasticity, so that the limit block 8 enters the limit groove 9 to prevent the bracket 6 from falling off from the guide frame 3 when sliding upward.
