Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a stamping die that is convenient and accurate in positioning. Background Technology

[0002] Stamping positioning dies are a very important tool in stamping production. They are mainly used to ensure the accurate positioning of stamped parts during the stamping process, so as to guarantee the precision and consistency of the products.

[0003] With the advancement of technology, stamping positioning dies are also constantly evolving, employing advanced CNC machining technology, material technology, and surface treatment technology to improve the performance and service life of the dies.

[0004] In summary, stamping positioning dies play an important role in modern manufacturing, and their design and manufacturing level directly affects product quality and production efficiency.

[0005] Currently, when center-stamping or punching disc-shaped plates, the plates need to be placed in the groove of the die, and the punch moves up and down to press the plates, thereby achieving the shape pressing or hole forming processing of the plates. However, since some plates are quite thick, in order to ensure the quality of their forming or the effect of punching, they need to be heated to a red temperature to reduce the hardness of the metal plates, and then placed directly in the groove of the die for stamping. However, the high temperature of the metal plates during processing can cause the metal die to overheat, which can easily cause burns to workers. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a convenient and accurate positioning stamping die.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Design a stamping die that is easy to position accurately, including a base, a support plate fixed to the upper end of the base, an annular frame provided at the upper end of the support plate, and the lower end of the annular frame fixedly assembled with the surface of the support plate, a lower die slidably inserted into the inner side of the annular frame, and a concave die inserted into the interior of the lower die.

[0009] The upper end of the support plate is provided with a guide rod, and the lower end of the guide rod is welded and fixed to the surface of the support plate. The guide rods are symmetrically distributed along both sides of the annular frame. The surface of the guide rod is provided with a connecting plate. An inner sleeve is provided through the inside of the connecting plate, and the connection between the inner sleeve and the connecting plate is fixed by welding. The inner sleeve is slidably sleeved with the guide rod.

[0010] An upper mold is provided between two connecting plates. The ends of the connecting plates are welded and fixed to the edges of the upper mold. A punch is provided at the center of the upper mold, and the punch is fixed to the upper mold by screws.

[0011] In detail, a cylinder is fixed at the upper end of the base, and a through hole is provided through the surface of the support plate. The cylinder slides through the through hole, and the position of the cylinder corresponds one-to-one with the position of the connecting plate.

[0012] In detail, the cylinder has a piston rod inside for telescopic movement, and the end of the piston rod is fixedly assembled to the connecting plate with screws.

[0013] In detail, the guide rod is slidably fitted with a rod sleeve, and the outer ring wall of the rod sleeve is fixed with a side seat by a bracket. Side seats are respectively provided on both sides of the die.

[0014] In detail, threaded posts are provided at the lower ends of both sides of the die cavity, and the upper ends of the threaded posts are welded and fixed to the surface of the die cavity. A collar is provided through the inside of the side seat, and the connection position between the collar and the side seat is fixed by welding. The threaded posts and the collar are slidably connected through the surface of the collar.

[0015] In detail, the end of the threaded column is provided with a threaded sleeve, the end face of the threaded sleeve is tightly fitted with the end face of the collar, and a knob is fixed on the outer ring wall of the threaded sleeve.

[0016] In detail, the annular frame has an annular cavity inside, and a mounting plate is installed through one side of the annular cavity. The mounting plate is fixed to the annular frame by welding.

[0017] In detail, the mounting plate is located inside the annular cavity and is covered with a filter screen. The edge of the filter screen is welded to the surface of the mounting plate, and the filter screen covers the outside of the cold water outlet and the cold water inlet.

[0018] The design scheme proposed in this utility model has the following beneficial effects in application:

[0019] 1. The positioning of the lower die and the ring frame ensures the stability of the lower die and the support plate. The lower die also supports the die cavity, ensuring the accuracy and stability of the stamping process. The extension and retraction of the piston rod of the cylinder can drive the punch of the upper die to move downward and stamp the disc plate in the die cavity to form or punch holes. The die cavity and the guide rod sleeve are connected and fixed by the side seat structure, which facilitates the disassembly and replacement of the die cavity structure or the periodic cleaning of the groove of the die cavity.

[0020] 2. The annular frame has an annular cavity inside, through which cold water can be injected into the annular cavity through the cold water inlet and circulated through the cold water outlet. This prevents the metal mold from conducting heat and causing burns to the operators when processing thick plates that need to be heated to a red-hot state. In addition, it can conduct heat to cool the workpiece after stamping. Attached Figure Description

[0030] An upper mold 18 is provided between two connecting plates 17. The ends of the connecting plates 17 are welded and fixed to the edges of the upper mold 18. A punch 19 is provided at the center of the upper mold 18, and the connection between the punch 19 and the upper mold 18 is fixedly assembled by screws.

[0031] It should be further explained that a cylinder 20 is fixed at the upper end of the base 10, and a through hole is provided through the surface of the support plate 11. The cylinder 20 is slidably connected through the through hole. The position of the cylinder 20 corresponds one-to-one with the position of the connecting plate 17. The cylinders 20 are distributed on both sides to ensure the stability of the upper mold 18 moving downward.

[0032] It should be further noted that the cylinder 20 is equipped with a piston rod for telescopic movement. The end of the piston rod is fixedly assembled with the connecting plate 17 by screws. The piston rod can ensure the stability of the upper mold 18 moving up and down.

[0033] It should be further explained that a rod sleeve 21 is slidably sleeved on the surface of the guide rod 15, and a side seat 22 is fixed to the outer ring wall of the rod sleeve 21 by a bracket. Side seats 22 are respectively provided on both sides of the die 14. The side seats 22 distributed on both sides can ensure the positioning and support of the die 14.

[0034] It should be further explained that threaded posts 23 are provided on both lower ends of the die cavity 14. The upper ends of the threaded posts 23 are welded and fixed to the surface of the die cavity 14. A collar 24 is provided through the inside of the side seat 22. The connection position of the collar 24 and the side seat 22 is fixed by welding. The threaded posts 23 and the collar 24 are slidably connected through the surface, which can realize the quick positioning and docking of the die cavity 14 and the side seat 22.

[0035] It should be further noted that a threaded sleeve 25 is provided at the end of the threaded post 23.

The threaded sleeve 25 and the threaded column 23 are threadedly connected to each other, which can realize the fixation of the die 14 and the side seat 22. Then, the die 14 is placed into the lower mold 13, which can realize the stable placement of the die 14 during stamping. By sliding the sleeve 21 on the guide rod 15, it can be ensured that the die 14 can only move up and down during stamping, avoiding the situation where there is a gap between the die and the lower mold 13, which would cause shaking and stamping errors.

[0039] When stamping or punching thick plates, the plates are first heated until red-hot and then placed into the die 14. The heated metal plates are easy to process. To avoid heat conduction in the metal mold structure, cold water is injected into the annular cavity 30 through the cold water inlet 33 and drained through the cold water outlet 32 ​​to achieve cold water circulation, thereby achieving the effect of water cooling and heat conduction.
