Description

Technical Field

[0001] The utility model relates to the technical field of automatic welding equipment, in particular to a continuous stamping and bending die for a seismic-resistant connecting piece. Background Art

[0002] Seismic connectors are important components used to improve seismic performance in structures such as buildings, bridges, and tunnels. They are connectors that can maintain the integrity and stability of the structure under strong vibrations. The design of one type of seismic connector includes parts that need to be bent and formed, which are used to connect the structure from two directions. When stamping such seismic connectors, existing engineering molds require personnel to manually pick up and place the product to the stamping position, which makes the stamping efficiency of the engineering molds low and also has certain operational safety issues.

[0003] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0004] The utility model provides a continuous stamping and bending die for a seismic-resistant connecting piece, which is used to solve the above-mentioned problem.

[0005] A technical solution adopted by the utility model is: to provide a continuous stamping and bending die for a seismic-resistant connector, comprising: an upper die base and a lower die base, wherein an upper punch is arranged on the upper die base, and a lower concave die is arranged on the lower die base at a position corresponding to the upper punch;

[0006] The lower die base is also provided with a first push rod and a second push rod, which are driven by the first cylinder and the second cylinder respectively, and the ends of the first push rod and the second push rod are closed to form a rough positioning area;

[0007] A stacking assembly is also provided in the movement direction of the second push rod for stacking the products to be punched. When the mold is closed, the second push rod pushes the product at the bottom of the stacking assembly to the rough positioning area, after which the product falls into the lower die and is punched.

[0008] Furthermore, a third push rod is provided on the lower die base, which is driven by a third cylinder and the driving direction is directed to the rough positioning area. A corresponding discharge trough is provided on the lower concave die. When the die is opened, the third push rod pushes the formed seismic-resistant connecting part out of the discharge trough.

[0009] Furthermore, the first cylinder, the second cylinder and the third cylinder are respectively arranged on the lower mold base through the first bottom plate, the second bottom plate and the third bottom plate, and a plurality of push rod limiters are arranged on the first bottom plate, the second bottom plate and the third bottom plate, which play a guiding and limiting role in the extension and retraction of the first push rod, the second push rod and the third push rod.

[0010] Furthermore, the stacking assembly includes a fixed frame, which is arranged on the second bottom plate through a fixed rod, and a space is reserved between the fixed frame and the second bottom plate for a second push rod to pass through. A stacking through hole is provided in the middle of the fixed frame, and a plurality of limiting rods are provided along the periphery of the stacking through hole. The products are stacked in the limiting rods, and the bottom product falls on the second bottom plate. When the mold is closed, the second push rod pushes the bottom product to the rough positioning area.

DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", "front", "back", "horizontal", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention. They cannot indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0022] See also Figures 1 to 4 , the first embodiment of the utility model provides a continuous stamping and bending die for a seismic-resistant connector, comprising: an upper die base 1 and a lower die base 2;

[0023] An upper punch 11 is provided on the upper die base 1, and a lower die 21 is provided on the lower die base 2 at a position corresponding to the upper punch 11. The upper punch 11 and the lower die 21 complete the stamping and bending forming of the product 3 through the action of the molding surface and the molding cavity;

[0024] The lower die base 2 is provided with a first push rod 222, a second push rod 232 and a third push rod 242, which are driven by the first cylinder 221, the second cylinder 231 and the third cylinder 241 respectively, wherein the first push rod 222 and the second push rod 232 form a rough positioning area when their ends are closed;

[0025] A stacking assembly is provided in the movement direction of the second push rod 232 for stacking the products 3 to be punched. When the mold is closed, the second push rod 232 pushes the product 3 at the bottom of the stacking assembly to the rough positioning area, and then the product 3 falls into the lower die 21 and is punched.

[0026] Specifically, the first cylinder 221, the second cylinder 231 and the third cylinder 241 are respectively arranged on the lower mold base 2 through the first base plate 22, the second base plate 23 and the third base plate 24, so that the structure on the lower mold base 2 is more flexible, and different products 3 can be adapted by adjusting the angles of each cylinder and the push rod and adjusting the profiles of the ends of the first and second push rods.

[0027] In order to make the cylinder more stable when driving the push rod, and the product can stably and accurately reach the rough positioning area, several push rod limiters are also set on each push rod:

[0028] The first push rod 222 has a relatively short travel distance, and only two lateral push rod limiters 223 are provided, which are located on both sides of the first push rod 222 and play a guiding and limiting role in the extension and retraction of the first push rod 222;

[0029] Since the second push rod 232 is to push the product 3 out of the stacking assembly and send it to the rough positioning area, the activity is relatively long, so ten lateral push rod limiters are provided, which are distributed on both sides of the second bottom plate 23, and play a guiding and limiting role for the extension and retraction of the second push rod 232;

[0030] The third push rod 242 is required to push the formed anti-seismic connector out of the discharge chute 211 , and two cross-type push rod limiters are provided, which are respectively located on the third bottom plate 24 and the lower concave mold 21 , and play a guiding and limiting role in the extension and retraction of the third push rod 242 .

[0031] The stacking assembly includes a fixed frame 233, which is arranged on the second bottom plate 23 through a fixed rod 234, and a space is reserved between the fixed frame 233 and the second bottom plate 23 for the second push rod 232 to pass through. The fixed frame 233 has a stacking through hole in the middle, and a plurality of limiting rods 235 are arranged along the periphery of the stacking through hole. The products 3 are stacked in the limiting rods 235, and the bottom product 3 falls on the second bottom plate 23;

[0032] When the mold is closed, the second push rod 232 pushes the bottom product 3 to the rough positioning area. After the mold is opened, the second push rod 232 retreats, and the stacked products 3 fall on the second bottom plate 23 again.

[0033] Specifically, the thickness of the second push rod 232 is smaller than the thickness of the product 3 so as to smoothly push the lowest product 3.

[0034] A positioning plate 25 is also provided on the lower die 21, and a fine positioning through hole is provided on the positioning plate 25. When the die is closed, the ends of the first push rod 222 and the second push rod 232 are closed, and the product 3 reaches the rough positioning area and falls from the rough positioning area into the fine positioning through hole under the influence of gravity, so that it can be stamped and formed more accurately.

[0035] Specifically, the positioning plate 25 has an opening, which is connected to the positioning through hole and is consistent with the direction of the discharge slot 211. When the mold is opened, the third push rod 242 extends to push the product 3 out of the discharge slot 211 and the opening.

[0036] The beneficial effects of the continuous stamping and bending die of the seismic-resistant connector of the utility model are:

[0037] 1. By setting the first and second drivable push rods and the stacking assembly for placing the products, the automatic placement of the products is realized. The second push rod pushes the product to the lower concave die and forms a rough positioning area with the first push rod to locate the product position. By setting the third drivable push rod, it cooperates with the lower concave die with the discharge trough to push the formed anti-seismic connector out of the discharge trough for blanking, which greatly shortens the loading and blanking time, realizes the automation of stamping, makes the stamping efficiency of the engineering mold extremely high, and eliminates safety hazards;

[0038] 2. The design of the bottom plate makes the lower die structure more flexible, and the design of the push rod limiter and the positioning plate makes the positioning more accurate.

[0039] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
