Description

Technical Field

A top column 10 is provided on the right half of the support platform 4. A first waste material cutting block 8 and a second waste material cutting block 9 respectively matching the first waste material cutting hole 6 and the second waste material cutting hole 7 are provided on the left section of the lower surface of the upper mold pressing plate 1. The lower surface of the upper mold pressing plate 1 is provided with a first waste material cutting block 8 and a second waste material cutting block 9 respectively matching the first waste material cutting hole 6. The right section on the surface is provided with a pressure column 11 that cooperates with the left and right sides of the top column 10, and the right end portion on the support platform 3 is provided with a top block 13. One side of the upper surface of the top block 13 is provided with a cutting edge. The connecting line segment between the side of the top block 13 with the cutting edge and the side of the second part A6-2 facing away from the first part A6-1 is parallel to the connecting line segment between the left and right ends of the cushion block 5. The top of the top block 13 is flush with the top of the top column 10, and a shear pressure block 12 that cooperates with the top block 13 is provided on the lower surface of the upper mold plate 1.

[0029] In this embodiment, when in use, a plate 24 is placed on the pad 5 between the upper die pressing plate 1 and the lower die pressing plate 2.

After that, the upper die pressing plate 1 leaves the lower die pressing plate 2, and the plate 24 is pulled toward the right end of the upper die pressing plate 1 by a machine (a robot or other conveying device) for a certain distance, and then the upper die pressing block 1 and the lower die pressing block 2 are molded together for a second cutting. At the same time, after the plate 24 is pulled to move, the first plate 24 is cut by the first excess material cutting hole 6 and the first excess material cutting hole. The portion of the cutout portion of block 8 that is not cut out by the second excess material cutting hole 7 and the second excess material cutting block 9 is just cut out by the second excess material cutting hole 7 and the second excess material cutting block 9 (the moving distance can be adjusted according to the actual situation). After that, the upper mold pressing plate 1 leaves the lower mold pressing plate 2, and the machine continues to pull the plate 24 to move, and the remaining portion after being cut out by the second excess material cutting block 9 and the second excess material cutting hole 7 and the first excess material cutting block 8 and the first excess material cutting hole 6 is moved to the top column 10, and then the upper mold pressing plate 1 is moved to the lower mold pressing plate 2 again, so that the pressing column 11 presses the plate 24 on the left side or right side or both sides of the top column 10, so that the portion of the plate 24 that is not supported by the top column 10 bends downward, and after one or more downward pressing of the pressing column 11 (such as Fig.12 After that, the thin plate U-shaped part 25 is formed. After that, the shearing block 12 on the upper die plate 1 and the top block 13 on the lower die plate 2 work together to cut the thin plate U-shaped part 25 from the plate 24. The whole process does not require manual participation, and the manufacturing process is continuous, which improves production efficiency.

[0030] As a preferred embodiment, the pad 5 is provided with two rows of the cutting hole groups and two rows of top pillars 10, each row of the cutting hole groups includes at least one pair of cutting hole pairs, each pair of cutting hole pairs includes at least one first excess material cutting hole 6 and one second excess material cutting hole 7, the queue of each row of the cutting hole groups is parallel to the connecting line segment between the left and right ends of the pad 5, the right side of each row of the cutting hole groups corresponds to a row of top pillars 10, the connecting line segment between a row of the cutting hole groups and the corresponding row of top pillars 10 is parallel to the connecting line segment between the left and right sides of the pad 5, each row of the top pillars 10 is parallel to the connecting line segment between the left and right ends of the pad 5, and the space between two adjacent top pillars 10 in each row The distance is equal to the distance between the first excess material cutting hole 6 and the second excess material cutting hole 7 in each row, the two rows of the cutting hole groups on the pad 5 are symmetrically arranged, and the two rows of the cutting hole groups are arranged facing each other on the side of the second part B7-2, and the symmetry axis between the two rows of the cutting hole groups is parallel to the connecting line segment between the left and right ends of the pad 5, the two rows of the top columns 10 are symmetrically arranged, and the symmetry axis between the two rows of the top columns 10 is parallel to the connecting line segment between the left and right ends of the pad 5, the top block 13 is set on the support platform 4 at one end of each row of top columns 10 facing away from the corresponding cutting hole group, and the shear pressure block 12 is located directly above the gap between the two rows of the top columns 10.

[0031] After such arrangement, two thin plate U-shaped parts 25 can be processed simultaneously on a plate, so that the shearing block 12 on the upper die plate 1 and the top block 13 on the lower die plate 2 can simultaneously cut off the two thin plate U-shaped parts 25 when they work together.

[0032] As a preferred embodiment, a second guide plate 15 is provided on the side of each row of the top pillars 10 on the lower die plate 2 facing away from the hole cutting group, the height of the right end of the second guide plate 15 is lower than the height of the left end, the connecting line segment between the left and right ends of a second guide plate 15 is colinear with the axis of a row of the top pillars 10, and the right end of the second guide plate 15 extends outside the lower die plate 2. By providing the second guide plate 15, the thin plate U-shaped parts 25 cut off by the shearing block 12 on the upper die plate 1 and the top block 13 on the lower die plate 2 are guided by the second guide plate 15 to the outside of the lower die plate 2 for easy collection.

[0033] As a preferred embodiment, the support platform 4 is further provided with a movable column 16 and a fixed column 17 that cooperate with each other in each row of the top columns 10. A shear column 18 parallel to the connecting line segment between the left and right ends of the support platform 4 is provided between the upper and lower ends of the movable column 16. The movable column 16 is connected to the support platform 4 through a linear elastic member. The fixed column 17 is fixedly arranged on the side of the shear column 18 facing away from the movable column 16. The telescopic direction of the linear elastic member is parallel to the connecting line segment between the left and right ends of the support platform 4. 6 has an inclined surface on the side facing away from the shear column 18, and the opening direction of the acute angle formed between the inclined surface and the upper surface of the support platform 4 faces the shear column 18.

The fixed column 17 is provided with a concave cavity 20 that opens downward, and the opening of the concave cavity 20 penetrates the lower surface of the support platform 4, and one end of the shear hole 21 extends into the concave cavity 20.

[0034] Since some thin plate U-shaped parts 25 need to be processed with through holes 26 on their side walls (such as Fig.14 ), therefore, after such arrangement, when the upper mold plate 1 and the lower mold plate 2 are closed, the extrusion block 19 squeezes the movable column 16 toward the fixed column 17, so that the shear column 18 on the movable column 16 and the shear hole 21 on the fixed column 17 work together to process the through hole 26, and the residual material sheared by the shear column 18 and the fixed column 17 leaves the fixed column 17 from the opening of the cavity 20.

One end of the spring 22 is fixedly connected to one end of the slide groove 23, and the other end of the spring 22 is fixedly connected to the moving column 16. After such arrangement, the slide groove 23 prevents the moving route of the moving column 14 from being deviated, and the arrangement of the spring 22 ensures that the moving column 16 automatically leaves the fixed column 17 after the extrusion block 19 moves upward along with the upper die plate 1.
