Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a multi-directional positioning stamping die. Background Technology

[0002] There are many types of stamping dies, which are also classified according to their working nature, die structure, and die material. Stamping dies are special process equipment used in cold stamping to process materials into parts. They are called cold stamping dies. Stamping is a pressure processing method in which pressure is applied to materials at room temperature using dies mounted on a press, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts. In traditional stamping dies, the upper and lower die holders are not properly guided and positioned during the stamping process.

[0003] According to a multi-directional positioning stamping die disclosed in the public notice (Announcement No.: CN211027785U), the aforementioned application includes a positioning mechanism that uses a lifting cylinder to drive a guide plate downwards, thereby causing the upper die base to move downwards as a whole, ensuring the stability of the stamping process. Simultaneously, a sliding rod slides within a sliding groove on the guide component, guiding the downward movement of the upper die base and preventing misalignment between the upper and lower die bases, thus improving the overall yield rate. Furthermore, the guide component is connected to a limiting plate via a connecting plate, facilitating subsequent disassembly and enhancing overall practicality.

[0004] However, in actual use, the upper die of the stamping die is usually guided by a pre-set guide rod. However, due to the impact operation of the stamping die, the upper die is prone to lateral displacement impact force when it is impacted, which can lead to collision and damage between the mounting part of the upper die and the guide rod, resulting in damage to the equipment. In view of this, we propose a multi-directional positioning stamping die. Utility Model Content

[0005] The purpose of this invention is to provide a multi-directional positioning stamping die to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-directional positioning stamping die, including a worktable, a fixed die fixedly installed on the inner wall of the upper surface of the worktable, a column fixedly installed on the upper surface of the worktable, a top frame fixedly installed on the top surface of the column, a hydraulic cylinder fixedly installed on the upper surface of the top frame, an installation plate fixedly installed on the output end of the hydraulic cylinder, a moving die fixedly installed on the lower surface of the installation plate, and a protective component provided inside the installation plate;

[0007] The protective component includes a mounting hole on the inner wall of a mounting plate. A protective ring is rotatably mounted on the inner surface of the mounting hole. An auxiliary ring is rotatably mounted on the lower surface of the protective ring. A positioning ring is fixedly mounted on the arc-shaped outer wall of the protective ring. A circular groove is formed on the arc-shaped inner surface of the protective ring. A contact wheel is rotatably mounted on the inner surface of the circular groove. An L-shaped ring is fixedly mounted on the lower surface of the protective ring. A coil spring is sleeved on the arc-shaped outer wall of the L-shaped ring.

[0008] Preferably, the column is disposed in the mounting hole, and the inner diameter of the protective ring is larger than the outer diameter of the column, so that the protective ring can move vertically along the outer surface of the mounting plate.

[0009] Preferably, the number of contact wheels is set to multiple sets, and the multiple sets of contact wheels are evenly distributed in a circumferential array on the arc-shaped inner surface of the protective ring. Furthermore, an arc-shaped groove is formed on the arc-shaped outer surface of the contact wheel, and the curvature of the arc-shaped groove is in contact with the outer surface of the column, thereby enabling the multiple sets of contact wheels to be more stably in contact with the outer surface of the column.

[0010] Preferably, the inner surface of the mounting hole has an annular opening with a thickness that matches the positioning ring, so that both the protective ring and the auxiliary ring can be stably installed inside the mounting hole, thereby maintaining a certain degree of stability in the vertical direction.

[0011] Preferably, the upper surface of the auxiliary ring is provided with an annular connecting groove that is adapted to the size of the L-shaped ring, so that the shape of the L-shaped ring can restrict the relative position of the protective ring and the auxiliary ring in the vertical direction.

[0012] Preferably, the mounting plate is provided with a heat dissipation assembly, which includes an air intake chamber. The air intake chamber is opened on the inner wall of the mounting plate and is connected to the inside of the mounting hole. The inner wall of the protective ring is provided with an annular cavity, and the inside of the protective ring is provided with a horizontal straight hole.

[0013] Preferably, the air intake chamber is arranged with its upper and lower ends connected, and the two ends of the straight hole are respectively connected to the annular cavity and the annular opening, so that the cavity at the center of the protective ring can be connected to the air intake chamber through the circular groove, the annular cavity, the straight hole and the annular opening.

[0014] Compared with the prior art, this utility model provides a multi-directional positioning stamping die, which has the following beneficial effects:

[0015] 1. This multi-directional positioning stamping die, by setting up protective components, the protective ring and auxiliary ring can move vertically along the outer surface of the column. The several contact wheels inside the two rings are staggered to provide stable lateral force support to the outer periphery of the column. This changes the original sliding friction to rolling friction, reduces the coefficient of friction while maintaining high stability, and ensures the stability and safety of the device during the stamping process.

[0016] 2. This multi-directional positioning stamping die, equipped with heat dissipation components, allows the mounting plate to move rapidly in the vertical direction, resulting in a faster airflow velocity in the suction chamber. This allows the heat generated by the rolling contact between the contact wheel and the column to enter the suction chamber through the circular groove, annular cavity, straight hole, and annular opening, and to be carried outwards. This effectively reduces the heat generated at the contact wheel due to rapid movement, preventing the outer surface of the column from becoming more easily worn due to heat during long-term operation, thus affecting the normal use of the device.

[0023] like Figures 1-5As shown, this utility model provides a technical solution: a multi-directional positioning stamping die, including a worktable 1, a fixed die 2 fixedly installed on the inner wall of the upper surface of the worktable 1, a column 3 fixedly installed on the upper surface of the worktable 1, a top frame 4 fixedly installed on the top surface of the column 3, a hydraulic cylinder 5 fixedly installed on the upper surface of the top frame 4, an installation plate 6 fixedly installed on the output end of the hydraulic cylinder 5, a moving die 21 fixedly installed on the lower surface of the installation plate 6, and a protective component 7 provided inside the installation plate 6. The protective component 7 includes a mounting hole 71, a protective ring 72, an auxiliary ring 73, a positioning ring 74, a circular groove 75, a contact wheel 76, an L-shaped ring 77, and a coil spring 78.

[0024] In one embodiment of this utility model, a mounting hole 71 is formed on the inner wall of the mounting plate 6. A protective ring 72 is rotatably mounted on the inner surface of the mounting hole 71. An auxiliary ring 73 is rotatably mounted on the lower surface of the protective ring 72. A positioning ring 74 is fixedly mounted on the arc-shaped outer wall of the protective ring 72. A circular groove 75 is formed on the arc-shaped inner surface of the protective ring 72. A contact wheel 76 is rotatably mounted on the inner surface of the circular groove 75. An L-shaped ring 77 is fixedly mounted on the lower surface of the protective ring 72. A coil spring 78 is sleeved on the arc-shaped outer wall of the L-shaped ring 77.

[0025] Furthermore, the moving mold 21 and the fixed mold 2 are arranged on the same vertical line. Four sets of columns 3 are arranged in a rectangular array on the worktable 1. Specifically, four sets of protective components 7 are arranged, each corresponding to one of the columns 3. The columns 3 are positioned within the mounting holes 71. The inner diameter of the protective ring 72 is larger than the outer diameter of the column 3, allowing the protective ring 72 to move vertically along the outer surface of the mounting plate 6. Multiple sets of contact wheels 76 are arranged in a circular array evenly distributed on the arc-shaped inner surface of the protective ring 72. Arc-shaped grooves are formed on the arc-shaped outer surface of the contact wheels 76, and the curvature of these grooves fits the outer surface of the column 3. This allows the multiple sets of contact wheels 76 to more stably fit the outer surface of the column 3, providing lateral support to the column 3 and ensuring the stability of the mounting plate 6 under stress.

[0026] In addition, an annular opening with a thickness matching that of the positioning ring 74 is provided on the arc-shaped inner surface of the mounting hole 71, so that the protective ring 72 and the auxiliary ring 73 can be stably installed inside the mounting hole 71, thereby maintaining a certain stability in the vertical direction. Furthermore, an annular connecting groove matching the size of the L-shaped ring 77 is provided on the upper surface of the auxiliary ring 73, so that the shape of the L-shaped ring 77 can restrict the relative position of the protective ring 72 and the auxiliary ring 73 in the vertical direction, so that the two will not separate. At the same time, the two ends of the coil spring 78 are fixedly connected to the bottom inner wall of the annular connecting groove and the arc-shaped outer wall of the positioning ring 74, respectively. In the initial state, the contact wheels 76 in the protective ring 72 and the auxiliary ring 73 are misaligned.

[0027] Furthermore, the mounting plate 6 is provided with a heat dissipation assembly 8 inside. The heat dissipation assembly 8 includes an air intake chamber 81, which is opened on the inner wall of the mounting plate 6 and is connected to the inside of the mounting hole 71. The inner wall of the protective ring 72 is provided with an annular cavity 82, and the inside of the protective ring 72 is provided with a horizontal straight hole 83.

[0028] In this embodiment of the invention, the suction chamber 81 is arranged with its upper and lower ends connected, and the two ends of the straight hole 83 are respectively connected to the annular cavity 82 and the annular opening. This allows the cavity at the center of the protective ring 72 to be connected to the suction chamber 81 through the circular groove 75, the annular cavity 82, the straight hole 83, and the annular opening. During the process of the mounting plate 6 being driven by the hydraulic cylinder 5 to move rapidly downward along the outer surface of the column 3 to achieve stamping, the airflow speed inside the suction chamber 81 is faster due to the absence of obstructions. According to Bernoulli's principle, the air pressure inside the suction chamber 81 is lower at this time. This allows the heat generated by the rolling of the contact wheel 76 at the center of the protective ring 72, which is the contact part between the contact wheel 76 and the column 3, to enter the suction chamber 81 through the circular groove 75, the annular cavity 82, the straight hole 83, and the annular opening and carry the heat outward. This effectively reduces the heat generated by the rapid movement of the contact wheel 76 and prevents the outer surface of the column 3 from being more easily worn due to heat during long-term operation, thus affecting the normal use of the device.

[0029] In this invention, during use, the workpiece to be processed is placed in the fixed mold 2. At this time, the hydraulic cylinder 5 is controlled to drive the mounting plate 6 to impact downward along the outer surface of the column 3, so that the moving mold 21 can stamp and form the workpiece to be processed in the fixed mold 2. During this process, by setting up the protective component 7, the protective ring 72 and the auxiliary ring 73 can move vertically along the outer surface of the column 3. The several contact wheels 76 inside them are staggered to provide a stable lateral force support effect on the periphery of the column 3, changing the original sliding friction into rolling friction, reducing the friction coefficient while maintaining high stability, and ensuring the stability and safety of the device during the stamping process.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
