Description

Technical Field

[0001] This utility model relates to the field of bending machine mold clamping, specifically an electro-hydraulic servo CNC bending machine mold quick clamping mechanism. Background Technology

[0002] The die fixing and clamping mechanism of a CNC bending machine is a device used to securely install and clamp the die in a CNC bending machine. Through precise design and structure, it ensures that the die will not loosen or shift during processing, thereby providing accurate bending angles and stable processing quality. This mechanism is usually made of high-strength materials and has reliable clamping force and adjustment functions to adapt to dies of different specifications and shapes. In CNC bending operations, the die fixing and clamping mechanism is a key component for improving production efficiency and processing accuracy.

[0003] Chinese patent CN213256696U discloses a bending machine mold fixing device, including a first connecting plate, a second connecting plate, a movable clamping plate, a fixed clamping plate, an operating rod, and a connecting shaft. The first connecting plate is detachably connected to the bending machine slider. The rotation of the operating rod drives the adjustment of the distance between the movable clamping plate and the fixed clamping plate to clamp the mold. This device can meet the needs of quick installation and disassembly of bending molds. At the same time, the manufacturing and application costs are low, which greatly reduces the cost of bending machine mold fixing devices.

[0004] The bending machine mold fixing device of the above-mentioned patent mainly clamps the two sides of the mold during the fixing process, but does not fit and clamp the two ends of the mold, causing the mold to shift in position during fixing and subsequent use, and the clamping stability is poor. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-clamping mechanism for an electro-hydraulic servo CNC bending machine mold. The module can be pressed and the clamping piece rotated to achieve initial quick clamping. When fully adapting a shorter module, the elasticity of the first spring and the lateral movement of the adapting block allow the adapting block to fit against the side of the module. Secondly, the fitting piece moves outside the movable rod to fit the module's width. Finally, bolts sequentially penetrate the fitting piece and the module to fix the module's position. This allows for final fixation after quick clamping and adaptation, solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-clamp mechanism for an electro-hydraulic servo CNC bending machine mold, comprising a base, a pair of first supports on both sides of the base, a clamping piece on one side of the outer side of the pair of first supports, the clamping piece being rotatably connected to the first supports via a connecting shaft, a movable cavity being transversely provided inside the clamping piece, an adapter block being slidably provided inside the movable cavity, a pair of second supports on both sides of the base, a first spring being provided between the adapter block and the second supports, the elasticity of the first spring actively pushing the adapter block to fit the module, actively fitting the module and adapting to the length of the module.

[0007] Preferably, a handle is provided laterally between the two second supports, and the handle is rotatably connected to the adapter block. The second support and the clamp are integral structures, and the two ends of the first spring are welded and fixed to the adapter block and the second support respectively. The handle can be placed on the outside of the second support to pull the adapter block, avoid the adapter block from moving repeatedly in the movable cavity, and improve the stability of the entire quick clamp structure.

[0008] Preferably, a module is provided at the upper end of the base, and an adhesive piece is provided at the middle position of the adapter block facing the module. The adhesive piece is embedded inside the adapter block and slidably connected to the inside of the adapter block. A movable rod is provided through the sliding position of the adapter block and the adhesive piece, and the movable rod is welded and fixed to the adapter block. The movable rod provides a stable movement trajectory for the adhesive piece, so that the adhesive piece can move towards the module and adapt to the thickness of the module.

[0009] Preferably, a second spring is provided around the outside of the movable rod, and the two ends of the second spring are welded and fixed to the bonding piece and the adapter block respectively. The elasticity of the second spring can actively move the bonding piece away from the mounting groove. When it is necessary to adapt and pass through the bolt, the user can manually push the bonding piece to actively make the bonding piece fit the module.

[0010] Preferably, the lower ends of both sides of the base are provided with grooves that connect with the external slots of the clips. The reserved grooves facilitate the storage of the clips after rotation, and prevent the base from affecting the rotation of the clips and the placement of the modules.

[0011] Preferably, the rear end of the module is provided with a mounting groove, which extends through and to both ends of the clamping piece. A bolt is provided through the inside of the mounting groove, and a nut that engages with the bolt thread is provided on one side of the outside of the mounting groove. The reserved mounting groove facilitates the bolt to be exposed after it passes through, and the nut can be rotated outside the bolt at the exposed position, which facilitates the clamping and fixing of the bolt to the adapted module.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention allows the module to be pressed down and the clamping piece to rotate, pre-clamping the two sides of the module for efficient clamping. Simultaneously, to accommodate modules of different lengths, the elasticity of the first spring actively pushes the adapter block, ensuring it fits snugly against both sides of the module. This adapts to the module's length when fixing it. Furthermore, when the bolt penetrates the fitting piece and enters the mounting slot after embedding into the module, the nut can rotate around the bolt outside the mounting slot, allowing the adapter block to adapt to the module's length. After the fitting piece slides outside the movable rod to adapt to the module's width, the module is stably and efficiently fixed and clamped. Attached Figure Description

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] like Figure 1 As shown, the quick-clamp mechanism of the electro-hydraulic servo CNC bending machine mold in this embodiment includes a base 1. The upper end of the base 1 is provided with a module 2 of the electro-hydraulic servo CNC bending machine mold. When the module 2 is pressed and quick-clamped, the base 1 can lift and support the upper module 2.

[0021] Furthermore, in order to pre-clamp both sides of the module 2, a pair of first brackets 3 are provided on both sides of the base 1. A clamping piece 4 is provided on one side of the outer side of the pair of first brackets 3, and the clamping piece 4 is "L" shaped. The bent position of the clamping piece 4 is rotatably connected to the first bracket 3 through the connecting shaft 5. After the module 2 is pressed down, the clamping piece 4 rotates within the pair of first brackets 3 with the connecting shaft 5 as the center.

[0022] Among them, such as Figure 2As shown, a torsion spring 6 is arranged around the outside of the connecting shaft 5, and the two ends of the torsion spring 6 are welded and fixed to the outer wall of the first bracket 3 and the connecting shaft 5 respectively. The elasticity of the torsion spring 6 can continuously give the clamp 4 a rotational force, and the clamps 4 on both sides of the base 1 rotate to the sides of the base 1 to achieve flipping.

[0023] To accommodate modules 2 of different lengths, a movable cavity 7 is provided transversely inside the clip 4. An adapter block 8 is provided inside the movable cavity 7, and the outside of the adapter block 8 is slidably connected to the inside of the movable cavity 7. The adapter block 8 can move towards the module 2 by moving within the movable cavity 7, and can also adapt to the length of the module 2 by moving towards the module 2.

[0024] The base 1 has a pair of second brackets 11 on both sides, and the second brackets 11 and the clamping piece 4 are integrated. A first spring 13 is provided between the adapter block 8 and the second brackets 11, and the two ends of the first spring 13 are welded and fixed to the adapter block 8 and the second brackets 11 respectively. The elasticity of the first spring 13 can actively push the adapter block 8 toward the module 2, so that the adapter block 8 can fit tightly against and adapt to the module 2.

[0025] In addition, in order to limit the movement of the adapter block 8 and improve the stability of the movement of the adapter block 8, a handle 12 is provided laterally between the two second brackets 11, and the handle 12 is rotatably connected to the adapter block 8. The adapter block 8 can be pulled laterally through the handle 12. At the same time, the rotation of the handle 12 can also cover the outside of the second bracket 11. The restriction of the handle 12 by the second bracket 11, combined with the elasticity of the first spring 13, can make the adapter block 8 stable during rotation.

[0026] To improve the stability of the bonding piece 10, a bonding piece 10 is provided at the middle position of the adapter block 8 facing the module 2. The bonding piece 10 is embedded inside the adapter block 8 and is slidably connected to the inside of the adapter block 8. A movable rod 9 is provided through the sliding position of the adapter block 8 and the bonding piece 10, and the movable rod 9 is welded and fixed to the adapter block 8. While the bonding piece 10 slides laterally inside the adapter block 8, it can move towards the module 2. The bonding piece 10 and the clamping piece 4 can clamp the module 2 to achieve the thickness adaptation of the module 2.

[0027] Furthermore, such as Figure 3 As shown, a second spring 17 is arranged around the outside of the movable rod 9, and the two ends of the second spring 17 are welded and fixed to the bonding piece 10 and the adapter block 8 respectively. The elasticity of the second spring 17 can actively push the bonding piece 10 away from the module 2.

[0028] To prevent the protruding clamp 4 from affecting the rotation of the base 1, the lower ends of both sides of the base 1 are provided with grooves 15. The grooves 15 are connected to the external slots of the clamp 4. When the clamp 4 rotates around the connecting shaft 5, it can fill into the groove 15. The reserved grooves 15 can prevent the clamp 4 from affecting the clamping of the module 2.

[0029] To improve the clamping effect on module 2, such as Figure 4 As shown, a mounting groove 16 is provided at the rear end of module 2. The mounting groove 16 extends through and to both ends of the clamping piece 4. A bolt is installed through the inside of the mounting groove 16. The mounting groove 16 extends into the fitting piece 10. A nut 14 is provided on one side of the outside of the mounting groove 16. The inside of the nut 14 is engaged with the external thread of the bolt. After the bolt passes through, the nut 14 can be rotated outside the bolt to fix the bolt. The nut 14 can fix the bolt and fix the module 2 at the same time, which can be adapted to the length and width of the module 2.

[0030] Working principle: After clamping and fixing module 2 of the electro-hydraulic servo CNC bending machine mold with clamping blocks, module 2 presses down on clamping plate 4 and presses clamping plate 4. After being pressed, clamping plate 4 rotates inside the first bracket 3 with connecting shaft 5 as the center. Clamping plate 4 rotates and wraps around both sides of module 2 to achieve quick clamping. When clamping shorter modules 2, after module 2 is pressed down, handle 12 rotates out from outside the second bracket 11. The elasticity of the first spring 13 causes the adapter block 8 to move towards module 2 and fit against both sides of module 2. The bolt passes through the fitting plate 10 and module 2 in sequence and then protrudes from the mounting groove 16. Rotate nut 14 outside the bolt protruding from the mounting groove 16 to fix the bolt and module 2. The length and thickness of the adapter module 2 are adapted to achieve quick clamping while stably clamping modules 2 of different sizes.
