Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and in particular relates to a stamping die with positioning function. Background Technology

[0002] A stamping die with positioning function is a die design that ensures that raw materials or semi-finished products are in a precise position during the stamping process through specific structures or technical means.

[0003] Traditional stamping die positioning functions typically involve cutting notches in the stamping material and then using positioning blocks on the die to position the material. This method requires cutting notches in the stamping material, increases process steps, reduces stamping efficiency, and still results in the stamping material shifting position even when only using notches and positioning blocks for positioning, leading to poor positioning results. Utility Model Content

[0004] The purpose of this invention is to provide a stamping die with a positioning function. Specifically, by setting a positioning part, the sheet metal to be stamped is placed on the lower die, and the sheet metal contacts the limiting strip. Then, an electric push rod is activated, driving the connecting plate on the right side to move to the left. Under the action of gears, the two racks move in opposite directions. At this time, the two moving frames approach each other, and after the positioning push shaft contacts the sheet metal, it pushes the sheet metal to the center of the lower die for positioning. This method can quickly complete the positioning, reduces the number of operation steps, and has a better positioning effect. It solves the problem of traditional stamping die positioning functions, which usually involve cutting notches in the stamping material and then using positioning blocks on the die to position the stamping material. This method requires cutting notches in the stamping material, increasing the process steps and reducing stamping efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a stamping die with a positioning function, including a base, a lower die being positioned on the top of the base, a limit strip being fixedly connected to the top of the lower die, and further comprising:

[0007] A positioning part is installed inside the base and is used to quickly position the stamped sheet metal.

[0008] The limiting strip is used to limit the front and rear directions of the stamped sheet metal, and the lower mold and the base are assembled together for easy installation and disassembly.

[0009] Furthermore, the lower mold has insertion holes at all four corners, two positioning blocks are fixedly connected to the bottom of the lower mold, the base has a cavity at the center, slots are provided at the front and rear positions inside the base, and threaded holes are provided at all four corners inside the base.

[0010] The lower mold is positioned by inserting a positioning block into a slot at its bottom. The lower mold is fixed to the base by inserting a bolt into the insertion hole and threading it into the threaded hole. The positioning block and the lower mold are integrally formed, which can improve the stability after the lower mold is installed.

[0011] Furthermore, the positioning part includes two movable frames, which are distributed on the left and right sides of the base;

[0012] A drive assembly, which is installed inside the base, is used to drive the moving frame to move.

[0013] A movable component, mounted on top of the movable frame, is used to achieve a flexible clamping function; and

[0014] A limiting component is mounted on the front and back of the drive component, and the limiting component is used to improve stability;

[0015] The drive assembly is used to drive the two moving frames to move closer and further apart, thereby quickly positioning the stamped sheet metal.

[0016] Furthermore, a connecting rod is provided at the end of the movable frame, and a positioning push shaft is fixedly connected to both the front and back of the connecting rod. The connecting rod is connected to the movable frame through a movable component. The positioning push shaft and the connecting rod are integrally formed, and the bottom of the positioning push shaft is slightly higher than the top of the lower mold.

[0017] When the positioning push shaft comes into contact with the stamping sheet, it pushes the sheet and uses the movable components to flexibly compress the sheet.

[0018] Furthermore, the drive assembly includes an electric push rod fixedly connected to the inner wall of the base and two racks. Each of the two racks is fixedly connected to a connecting plate on the side away from each other. The bottom of the movable frame slides through the base and extends to the surface of the connecting plate for fixed connection. The racks are used to drive the movable frame to move. Since the lower mold is detachable, it is convenient to maintain the parts of the drive assembly in the future.

[0019] The output end of the electric push rod is fixedly connected to the connecting plate on the right side, and the two racks are meshed with gears on their sides that are close to each other. The center of the gears is rotatably connected to the base through a rotating shaft.

[0020] Furthermore, the movable component includes a baffle fixedly connected to the outside of the connecting rod, and two limiting grooves are opened on the top of the movable frame. A limiting rod is slidably connected inside the limiting groove. The limiting rod is fixedly connected to the surface of the connecting rod on the side facing the connecting rod, and a spring is sleeved on the outside of the limiting rod. The baffle is installed on the connecting rod by welding and is used for blocking.

[0021] The limiting rod is used to support and limit the connecting rod. One end of the spring is fixedly connected to the connecting rod, and the other end of the spring is fixedly connected to the surface of the moving frame. When the positioning push shaft is pushed, the spring is compressed, so that the positioning push shaft can be springed back to its original position by elastic force.

[0022] Furthermore, the limiting component includes a limiting plate slidably connected to the outside of the rack, a stabilizing protrusion fixedly connected to the side of the limiting plate facing the rack, a sliding groove opened on the side of the rack facing the limiting plate, and the stabilizing protrusion slidably connected inside the sliding groove; the stabilizing protrusion and the limiting plate are integrally formed, and the rack slides on the stabilizing protrusion, enabling it to move in a linear manner;

[0023] The stabilizing ridge is used to support the rack and improve the stability of the rack during movement.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model, by setting a positioning part, specifically places the sheet metal to be stamped on the lower mold and contacts the sheet metal with the limiting strip. Then, the electric push rod is activated to drive the connecting plate on the right side to move to the left. Under the action of the gear, the two racks move in opposite directions. At this time, the two moving frames approach each other, and after the positioning push shaft contacts the sheet metal, it will push the sheet metal to the center of the lower mold for positioning. This method can quickly complete the positioning, reduce the operation steps, and has a better positioning effect.

[0026] 2. This utility model uses a movable component. Specifically, after the push shaft positions the plate, the moving frame will move a certain distance again. At this time, the positioning push shaft is limited by the plate and does not move. The limiting rod slides in the limiting groove and squeezes the spring to achieve the purpose of flexible compression. This avoids the positioning push shaft from continuously moving and squeezing and deforming the plate, effectively protecting the plate from damage.

[0027] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0037] Please see Figures 1-5 As shown, this utility model is a stamping die with a positioning function, including a base 1, a lower die 11 positioned on the top of the base 1, a limit strip 12 fixedly connected to the top of the lower die 11, and further including:

[0038] Positioning part 2 is installed inside the base 1 and is used to quickly position the stamped sheet metal.

[0039] The limiting strip 12 is used to limit the front and rear directions of the stamped sheet metal. The lower mold 11 and the base 1 are assembled together for easy installation and disassembly.

[0040] The lower mold 11 has four holes 111 at its four corners. Two positioning blocks 112 are fixedly connected to the bottom of the lower mold 11. The center of the base 1 is hollow. The base 1 has slots 13 at the front and rear positions. The base 1 has threaded holes 14 at its four corners.

[0041] The lower mold 11 is inserted into the slot 13 via the positioning block 112 at the bottom, which is used to position the lower mold 11 during installation. The lower mold 11 is fixed on the base 1 by inserting a bolt into the insertion hole 111 and threading it into the threaded hole 14.

[0042] The positioning part 2 includes two movable frames 21, which are distributed on the left and right sides of the base 1;

[0043] Drive component 22 is installed inside the base 1 and is used to drive the moving frame 21 to move.

[0044] Movable component 23, mounted on top of the movable frame 21, serves to achieve flexible clamping; and

[0045] Limiting component 24 is installed on the front and back of drive component 22, and the limiting component 24 is used to improve stability;

[0046] The drive assembly 22 is used to drive the two moving frames 21 to move closer and further apart, thereby quickly positioning the stamped sheet metal.

[0047] A connecting rod 211 is provided at the end of the movable frame 21. Positioning push shafts 212 are fixedly connected to both the front and back of the connecting rod 211. The connecting rod 211 is connected to the movable frame 21 via a movable component 23.

[0048] When the positioning push shaft 212 comes into contact with the stamping sheet, it will push the sheet and use the movable component 23 to flexibly squeeze the sheet.

[0049] The drive assembly 22 includes an electric push rod 221 fixedly connected to the inner wall of the base 1 and two racks 222. A connecting plate 213 is fixedly connected to the side of the two racks 222 that are far apart from each other. The bottom of the moving frame 21 slides through the base 1 and extends to the surface of the connecting plate 213 for fixed connection. The sheet material to be stamped is placed on the lower mold 11 and the sheet material is brought into contact with the limiting strip 12. Then, the electric push rod 221 is activated to drive the connecting plate 213 on the right side to move to the left. Under the action of the gear 223, the two racks 222 move in opposite directions. At this time, the two moving frames 21 are close to each other. After the positioning push shaft 212 contacts the sheet material, it will push the sheet material to the center of the lower mold 11 for positioning. This method can quickly complete the positioning, reduce the operation steps, and has a better positioning effect.

[0050] Among them, the output end of the electric push rod 221 is fixedly connected to the connecting plate 213 on the right side, and the two racks 222 are meshed with a gear 223 on the side close to each other. The center of the gear 223 is rotatably connected to the base 1 through a rotating shaft.

[0051] The movable component 23 includes a baffle 231 fixedly connected to the outside of the connecting rod 211. The top of the movable frame 21 has two limiting grooves 232. A limiting rod 233 is slidably connected inside the limiting grooves 232. The limiting rod 233 is fixedly connected to the surface of the connecting rod 211 on the side facing the connecting rod 211. A spring 234 is sleeved on the outside of the limiting rod 233. After the positioning push shaft 212 positions the plate, the movable frame 21 will move a certain distance again. At this time, the positioning push shaft 212 is limited by the plate and does not move. The limiting rod 233 slides in the limiting groove 232 and squeezes the spring 234 to achieve the purpose of flexible compression, thereby avoiding the continuous movement of the positioning push shaft 212 from squeezing and deforming the plate, and effectively protecting the plate from damage.

[0052] The limiting rod 233 is used to support the connecting rod 211 and limit the connecting rod 211. One end of the spring 234 is fixedly connected to the connecting rod 211, and the other end of the spring 234 is fixedly connected to the surface of the moving frame 21. When the positioning push shaft 212 is pushed, the spring 234 is squeezed, which makes it easy to spring back the positioning push shaft 212 to reset through elastic force.

[0053] The limiting component 24 includes a limiting plate 241 slidably connected to the outside of the rack 222. A stabilizing protrusion 242 is fixedly connected to the side of the limiting plate 241 facing the rack 222. A sliding groove 243 is opened on the side of the rack 222 facing the limiting plate 241, and the stabilizing protrusion 242 is slidably connected inside the sliding groove 243.

[0054] The stabilizing rib 242 is used to support the rack 222 and improve the stability of the rack 222 during movement.

[0055] One specific application of this embodiment is:

[0056] In use, the base 1 is installed on the stamping machine. Then, the lower die 11 is inserted into the slot 13 on the base 1 through the positioning block 112 at the bottom. At this time, the lower die 11 and the base 1 are aligned and positioned by the positioning block 112, so that the insertion hole 111 and the threaded hole 14 on the lower die 11 are aligned. Then, the mounting bolts are used to fix the lower die 11 and the base 1. When stamping is required, the sheet metal to be stamped is placed on the lower die 11 and the sheet metal is brought into contact with the limit strip 12. Then, the electric push rod 221 is started to drive the connecting plate 213 on the right to move to the left. At this time, the moving frame 21 will move together, and drive the connecting rod 211 and the positioning push shaft 212 to move together. At the same time, the rack 222 in front moves to the left. At this time, the gear 223 will be pushed to rotate, which will drive the rack 222 in the rear to move to the right. At this time, the two moving frames 21 are close to each other, and the rack 222 will be stabilized on the limit plate 241 through the slide groove 243 during movement. The sliding of the convex strip 242 makes the movement of the rack 222 more stable. As the two moving frames 21 approach each other, the positioning push shaft 212 contacts the plate and pushes the plate to the center of the lower mold 11, positioning the plate at the center of the lower mold 11. This method can quickly complete the plate positioning. Since the plate may have certain size differences, after the positioning push shaft 212 positions the plate, the moving frame 21 will move a distance again. At this time, the positioning push shaft 212 is limited by the plate and does not move. The limiting rod 233 slides in the limiting groove 232 and squeezes the spring 234, thereby preventing the positioning push shaft 212 from continuously moving and deforming the plate, effectively protecting the plate from damage. After the plate is positioned, the electric push rod 221 is activated to move in the opposite direction, causing the two moving frames 21 to move away from each other and the positioning push shaft 212 to leave the lower mold 11, so that the stamping work can be performed. The lower mold 11 is detachable, which is convenient for subsequent replacement with different lower molds 11.
