Description

Technical Field

[0001] This invention relates to the technical field of plate chamfering, and more particularly to a structural device for processing high yield strength plate chamfers. Background Technology

[0002] Chamfering is a common process in sheet metal processing. This process requires manual support for bending, which is inefficient. During chamfering, the two ends of the bending area will have bulges due to compression, affecting the flatness of the side of the sheet after bending. In addition, when bending the radius corner quickly, the inner bend corner will have wrinkles, and the outer bend corner may have a chance of tearing, affecting the pass rate of sheet metal bending. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a structural device for processing high yield strength plates with chamfering to reduce plate bending damage and improve the pass rate and efficiency.

[0004] Based on the technical problems existing in the background art, the present invention proposes a structural device for processing the chamfering of high yield strength plates, including an upper mold, a lower mold, a positioning mechanism for positioning the plate and a side mold. The upper mold and the lower mold slide relative to each other. The positioning mechanism is installed on the lower mold and positions the plate. The side mold is installed on the upper mold and vertically processes the bending angle of the plate. The lower mold has a discharge mechanism installed on both sides. The discharge mechanism abuts against the bending angle of the plate and pushes the plate away from the lower mold.

[0005] Preferably, the upper mold includes an upper mold base, an upper mold pad, a ejector block, a die insert, and a die fixing plate. Two die fixing plates are installed on both sides below the upper mold pad, and die inserts are installed on the inner sides of both die fixing plates. The ejector block is slidably installed between the die inserts.

[0006] Preferably, a guide mechanism is installed on the upper mold base, the guide mechanism passes through the upper mold base and the upper mold pad and is connected to the ejector block, and the guide mechanism guides longitudinal sliding.

[0007] Preferably, the thickness of the punch block is the same as the thickness at the junction of the die insert and the punch block.

[0008] Preferably, a horizontally sliding side mold is installed below the concave mold fixing plate.

[0009] Preferably, the lower mold includes a lower mold base and a lower punch, with the lower punch mounted above the lower mold base and matching the die insert.

[0010] Preferably, the two sides of the concave mold insert are beveled, the beveled angles include concave angles and convex angles, the two sides of the upper mold are right angles, the distance between the two right angles is equal to the distance between the convex angles, and the distance between the two concave angles is less than the distance between the two right angles.

[0011] Preferably, longitudinally sliding movable blocks are installed on both sides of the lower punch, the sliding distance of the movable blocks is fixed, and the side mold is located between the die fixing plate and the movable blocks.

[0012] Preferably, the material discharge mechanism is installed on the lower mold base and located below the movable block.

[0013] Preferably, the lower mold base is slidably connected to the upper mold base.

[0014] Compared with existing technologies, the structural device for processing high yield strength plates proposed in this invention, using the above-mentioned technical solution, achieves the following technical effects:

[0015] This invention enables the bending of both sides of a sheet material through the pressing of an upper and lower mold. The bent area of ​​the sheet material becomes thinner and has an inclined angle. The already bent area is then pressed by a side mold, causing the sheet material to bend again. The two bending angles are close together and the bending points are different. By combining them, a 90-degree bend of the sheet material can be achieved, reducing the degree of bending and the risk of material tearing. At the same time, the pressing of the mold can avoid the situation of the inner inclined angle protruding, making the pressing of the sheet material smoother. Attached Figure Description

[0021] Example

[0022] Please refer to Figures 1-2 This invention proposes a structural device for processing high yield strength sheet chamfers, including an upper mold 1, a lower mold 2, a positioning mechanism 3 for positioning the sheet, and a side mold 4. The upper mold 1 and the lower mold 2 slide relative to each other. The positioning mechanism 3 is installed on the lower mold 2 and positions the sheet. The side mold 4 is installed on the upper mold 1 and vertically processes the bending angle of the sheet. Discharge mechanisms 5 are installed on both sides of the lower mold 2. The discharge mechanisms 5 abut against the bending angle of the sheet and push the sheet away from the lower mold 2. In this invention, the positioning mechanism 3 is installed on the lower mold 2. The positioning mechanism 3 is rod-shaped and stands on the lower mold 2. The length of the positioning mechanism 3 protruding from the lower mold 2 is less than the thickness of the plate. The plate is rectangular and has holes corresponding to the positioning mechanism 3. The holes of the plate are engaged with the positioning mechanism 3. The lower mold 2 presses the plate downward. The protruding part of the lower mold 2 matches the groove of the upper mold 1. The length of the plate is longer than the groove. After pressing, the two sides of the plate will be bent. The side mold 4 will be located between the upper mold 1 and the lower mold 2 and on both sides of the plate. The side mold 4 will move closer to the plate and squeeze the bent plate to form a 90-degree angle to complete the folding. After the folding is completed, the upper mold 1 moves upward, and the discharge mechanism 5 will push the folded plate out of the lower mold 2.

[0023] In a specific embodiment, refer to Figure 1 , Figure 2The upper mold 1 includes an upper mold base 11, an upper mold pad 12, a ejector block 13, a die insert 14, and a die fixing plate 15. Two die fixing plates 15 are installed on both sides below the upper mold pad 12. Die inserts 14 are installed on the inner sides of both die fixing plates 15. The ejector block 13 is slidably installed between the die inserts 14. The two die inserts 14 are located on both sides below the upper mold base 11 and clamp the ejector block 13 between them, forming the main pressing part of the upper mold 1. When the sheet metal is stuck on the upper mold 1, the sheet metal can be pushed out and removed from the upper mold 1 by moving the ejector block 13 downward.

[0024] In a specific embodiment, refer to Figure 1 , Figure 2 A guide mechanism 6 is installed on the upper mold base 11. The guide mechanism 6 passes through the upper mold base 11 and the upper mold pad 12 and is connected to the ejector block 13. The guide mechanism 6 guides the ejector block 13 to slide longitudinally. The guide mechanism 6 is used to drive the ejector block 13 to slide longitudinally. It can control the ejector block 13 and the die insert 14 to form a complete groove of the upper mold 1. It can also move to push out the sheet metal.

[0025] In a specific embodiment, refer to Figure 1 , Figure 2 The thickness of the ejector block 13 is the same as the thickness at the junction of the die insert 14 and the ejector block 13. Since the thickness of the ejector block 13 is the same as the thickness of the thinner part of the die insert 14, the two die inserts 14 and the ejector block 13 can form a smooth and complete groove.

[0026] In a specific embodiment, refer to Figure 1 , Figure 2 A horizontally sliding side mold 4 is installed below the die fixing plate 15.

[0027] In a specific embodiment, refer to Figure 1 , Figure 2 The lower mold 2 includes a lower mold base 21 and a lower punch 22. The lower punch 22 is installed above the lower mold base 21 and matches the die insert 14.

[0028] In a specific embodiment, refer to Figure 1 , Figure 2 The two sides of the concave mold insert 14 are beveled, including an inner concave angle 71 and an outer convex angle 72. The two sides of the upper mold 1 are right angles 221. The distance between the two right angles 221 is equal to the distance between the outer convex angles 72, and the distance between the two inner concave angles 71 is less than the distance between the two right angles 221. The beveled angles on both sides can guide the sheet metal to bend into an obtuse angle when the sheet metal is pressed. The bent sheet metal will be located between the concave mold fixed plate 15 and the movable block 23. Then, the side mold 4 pushes the bent sheet metal to squeeze it. The right angle 221 between the side mold 4 and the lower punch 22 will squeeze the sheet metal to form a 90-degree angle.

[0029] In a specific embodiment, refer to Figure 1 , Figure 2 The lower punch 22 has longitudinally sliding movable blocks 23 installed on both sides. The sliding distance of the movable blocks 23 is fixed. The side mold 4 is located between the die fixing plate 15 and the movable blocks 23.

[0030] In a specific embodiment, refer to Figure 1 , Figure 2 The material discharge mechanism 5 is installed on the lower mold base 21 and located below the movable block 23.

[0031] In a specific embodiment, refer to Figure 1 , Figure 2 The lower mold base 21 is slidably connected to the upper mold base 11. The upper mold base 11 and the lower mold base 21 can drive the two upper and lower molds 2 to clamp and bend and press the sheet metal.
