Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a clamp-free bending edge processing mold. Background Technology

[0002] Machining is a precision processing method that uses various machining equipment to cut and shape metal materials. Parts manufactured through machining typically have strict requirements for dimensional accuracy and surface quality, and their performance directly affects the overall working efficiency and reliability of the equipment.

[0003] In sheet metal forming, to create bent edges with multiple bends, it's often necessary to first clamp the sheet metal to prevent displacement during forming and subsequent processing failure. Currently, the clamping operation is mainly manual: operators must manually operate the clamps to stably hold the sheet metal, and only after confirming proper clamping can subsequent forming processes proceed. However, this manual-operated clamping method increases the workload of operators, and the frequent clamping and unclamping operations make the process cumbersome, resulting in low overall work efficiency.

[0004] Therefore, how to design a bending edge processing mold that can reduce the labor intensity of workers and improve work efficiency is a technical problem that has not yet been solved in the existing technology. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the technical defects of the prior art, which requires manual operation for pressing and fixing the sheet metal, resulting in high labor intensity, complicated procedures and low work efficiency.

The end face of the forming block facing the stepped forming bottom surface is the stepped forming top surface. The forming block can be driven by the forming top mold to move up and down relative to the forming bottom mold.

An elastic rubber pad is installed inside the mounting cavity, located above the connecting plate; When the forming top mold is pressed down, the movable pressing block follows the forming top mold and gradually presses against the high surface of the stepped forming bottom surface; as the forming top mold continues to press down, the movable pressing block squeezes the elastic rubber pad upward under the obstruction of the high surface, and the movable pressing block retracts upward relative to the forming top mold until the forming pressing block presses against the low surface of the stepped forming bottom surface.

[0011] As a preferred embodiment, it also includes a plug-in slot formed on the side of the connecting plate facing the movable pressing block; the other end of the plug-in plate passes through the elongated mounting opening and is matched and plugged into the plug-in slot.

The end face of the forming pressure block facing the stepped forming bottom surface is the stepped forming top surface. The forming pressure block can be driven by the forming top mold to move up and down relative to the forming bottom mold. When the forming pressure block moves down to the lowest point, the stepped forming top surface can cooperate with the stepped forming bottom surface to process the plate into a bent edge.

[0015] In the sheet metal processing, the sheet metal to be processed, which has already been bent at 90°, is first placed on the stepped forming bottom surface, with one end in contact with the forming limiting block and the other end extending downwards along the outer wall of the high surface of the stepped forming bottom surface.

This utility model of a clamp-free bending edge processing mold allows the forming top mold to press down and drive the pressure roller to automatically press and fix the sheet metal. The processing process requires no manual operation, which reduces the labor intensity of workers and eliminates extra time consumption, thereby significantly improving work efficiency.

[0029] During the sheet metal processing, the sheet metal to be processed, which has already been bent at 90°, is first placed on the stepped forming bottom surface 11, with one end in contact with the forming limiting block 2 and the other end extending downward along the outer wall of the high surface 15 of the stepped forming bottom surface 11. After the sheet metal is accurately positioned, the hydraulic equipment is activated to drive the forming top mold 3 to move downward, driving the pressure roller 4 to move downward along the sheet metal surface on the outer wall of the high surface 15 and press it firmly. The forming top mold 3 continues to press down, driving the forming pressure block 5 to press the sheet metal tightly against the stepped forming bottom surface 11.

[0032] The forming block 5 includes a movable pressing block 51 and a forming pressing block 52; wherein, the movable pressing block 51 is telescopically mounted on the forming top mold 3 and is vertically opposite to the high surface 15 of the stepped forming bottom surface 11; the forming pressing block 52 is fixedly disposed on the forming top mold 3 and is vertically opposite to the low surface 14 of the stepped forming bottom surface 11, and the position of the forming pressing block 52 is higher than the initial position of the movable pressing block 51.

[0033] The movable pressing block 51 is retractably mounted on the forming top mold 3 via a movable mounting structure; the movable mounting structure includes a mounting chamber 6, a long mounting opening 61, a connecting plate 62, a plug-in plate 63, and an elastic rubber pad 64; wherein, there is at least one mounting chamber 6, formed on the forming top mold 3; the long mounting opening 61 is formed on the inner bottom wall of the mounting chamber 6; the connecting plate 62 is installed inside the mounting chamber 6; one end of the plug-in plate 63 is fixedly disposed on the movable pressing block 51, and the other end passes through the long mounting opening 61 and is fixedly attached to the connecting plate 62. Fixed connection; the elastic rubber pad 64 is installed in the mounting chamber 6, located above the connecting plate 62; when the forming top mold 3 is pressed down, the movable pressing block 51 follows the forming top mold 3 and presses down, gradually pressing against the high surface 15 of the stepped forming bottom surface 11; as the forming top mold 3 continues to press down, the movable pressing block 51, blocked by the high surface 15, squeezes the elastic rubber pad 64 upward, and the movable pressing block 51 retracts upward relative to the forming top mold 3 until the forming pressing block 52 presses against the low surface 14 of the stepped forming bottom surface 11.

[0034] The mounting chamber 6 has four parts formed on the forming top mold 3, and four elongated mounting openings 61, connecting plates 62, plug-in plates 63 and elastic rubber pads 64 that match the mounting chamber 6 are provided. like Figure 3-4 As shown, it also includes a plug-in slot 65, which is formed on the side of the connecting plate 62 facing the movable pressing block 51; the other end of the plug-in plate 63 passes through the elongated mounting opening 61 and is matched and plugged into the plug-in slot 65.

The guide cylinders 13 are matched and inserted into the guide holes 12, and can move up and down along the guide holes 12, thereby guiding the up and down movement of the forming top mold 3. Through the insertion and cooperation of the guide cylinders 13 and the guide holes 12, a precise trajectory constraint is provided for the vertical movement of the forming top mold 3, preventing deviation during movement.

[0037] The clamp-free bending edge processing mold in this embodiment is used as follows: During the sheet metal processing, the sheet metal to be processed, which has been processed into a 90° bend, is first placed on the stepped forming bottom surface 11, with one end in contact with the forming limiting block 2 and the other end extending downward along the outer side wall of the high surface 15 of the stepped forming bottom surface 11. After the sheet metal is accurately positioned, the hydraulic equipment is started to drive the forming top mold 3 to move downward, and the pressure roller 4 moves downward along the sheet metal surface on the outer side wall of the high surface 15 and presses it firmly. The forming top mold 3 continues to press down, and the movable pressing block 51 follows the forming top mold 3 to press down, gradually pressing against the high surface 15 of the stepped forming bottom surface 11. Under the obstruction of the high surface 15, the movable pressing block 51 presses upward against the elastic rubber pad 64, causing the movable pressing block 51 to retract upward relative to the forming top mold 3 until the forming pressing block 52 presses against the low surface 14 of the stepped forming bottom surface 11. With the cooperation of the stepped forming bottom surface 11 and the stepped forming top surface 53, the sheet metal is finally processed into a bent edge.
