Description

Technical Field

[0001] This utility model relates to the field of stamping technology, specifically to a steel stamping device for steel drum production. Background Technology

[0002] The process of stamping steel into steel drums involves stamping. Cut steel sheets are placed into a stamping press, which uses specific dies to press the flat sheet into the shape of a steel drum. After the steel is stamped into a drum shape in the device, a hydraulic system and an upper die are used to lift the drum, which is fitted onto a lower die. Due to the drum's own weight, it may fall downwards within the upper die, posing a slight safety risk. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a steel stamping device for steel drum production, so as to solve the problem mentioned in the background art that the steel drum may fall downward when it is pulled upward by the upper mold and the hydraulic system away from the lower mold.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a steel stamping device for steel drum production, comprising a mold base and guide columns installed at the four corners of the top of the mold base, a hydraulic assembly installed on the four guide columns, an upper mold assembly installed at the bottom of the hydraulic assembly for stamping steel into a steel drum and lifting it upwards, and a side protection assembly installed on the upper mold assembly for providing bottom protection when lifting the steel drum upwards;

[0005] The side protection assembly includes leveling groove plates installed on both sides of the upper mold assembly. Insertion pins are rotatably installed inside the two leveling groove plates, and protective strips are installed on the two insertion pins. A motor for driving the protective strip to rotate and adjust it below the upper mold assembly is installed on one of the leveling groove plates.

[0006] Preferably, the upper mold assembly includes an outer mold kit disposed above the center of the mold base, an arc-shaped plate is fitted into the inner wall of the outer mold kit, and an electric push rod is installed on the outer surface of the outer mold kit to compress the two sides when the steel barrel is lifted upward away from the mold base.

[0007] Preferably, the hydraulic assembly includes a top mount fixedly mounted on four guide columns, on which two hydraulic systems are mounted side by side.

[0008] Preferably, a lower pressure plate is slidably mounted on the four guide columns, with its top connected to the free end of the hydraulic system, and an insertion block is installed in the middle of the bottom surface of the lower pressure plate.

[0009] Preferably, the top of the outer mold kit is equipped with two mating blocks arranged side by side, and the distance between the two mating blocks is the same as the thickness of the socket block. A locking structure that passes through the socket block and the other mating block in sequence is installed on one of the mating blocks.

[0010] Preferably, the mold base includes a load-bearing base body, a slot is provided in the middle of the top surface of the load-bearing base body, an inner mold kit adapted to the outer mold kit is installed on the bottom wall of the slot, a plurality of elastic structures are installed on the bottom wall of the slot, and an annular plate surrounding the outer surface of the inner mold kit is installed on the top of the plurality of elastic structures.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, when the hydraulic component, in conjunction with the upper mold component, lifts the stamped steel barrel upward away from the mold seat, the protective strip is rotated downward by the running motor at least 90°, adjusting the protective strip, which is horizontally arranged on the side of the upper mold component, to the bottom, forming a protective barrier under the steel barrel inside the upper mold component, thus preventing the steel barrel from falling straight down when it moves upward.

[0013] 2. In this utility model, after the steel barrel is stamped, it can move upward together with the upper mold assembly and be taken away from the mold base. During this process, new steel can be put into the mold base. At the same time, after the upper mold assembly moves to the set position, the formed steel barrel is pulled out. Then the hydraulic assembly continues to drive the upper mold assembly to press downward, effectively optimizing the overall efficiency of stamping multiple steel barrels.

[0019] 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 protection scope of the present utility model.

[0020] After the steel is stamped in the stamping device, it generally takes a long time for the upper and lower dies to separate and create a certain distance before the steel drum fitted on the lower die can be pulled out and new steel can be fed in. This waiting time is relatively long. To effectively optimize the overall efficiency of stamping large quantities of steel drums, please refer to [the relevant documentation / resource]. Figures 1-4 This utility model provides a steel stamping device for steel drum production. The mold base 1 serves as the carrier structure of the entire stamping device, welded together with guide pillars 2 installed at the four corners of the top. Hydraulic components 3 are installed near the top of the four guide pillars 2, thus reserving sufficient space for the extrusion operation. An upper mold component 4 installed at the bottom of the hydraulic component 3 cooperates with the mold base 1 to stamp the steel into a steel drum shape and lift the drum upwards. During this process, workers can add new steel to the mold base 1. Simultaneously, after the upper mold component 4 moves to a set position, the formed steel drum is pulled out. Subsequently, the hydraulic component 3 continues to drive the upper mold component 4 downwards for extrusion, resulting in a relatively short overall time. Side protection components 5 installed on the upper mold component 4 provide bottom protection when lifting the steel drum upwards, preventing it from falling before workers can retrieve it.

[0021] After the steel is stamped into the shape of a steel drum in the device, during the process of using the upper mold assembly 4 to lift it upwards away from the mold base 1, the steel drum may fall. Figure 1 and Figure 2As shown, to effectively improve protection, the side protection assembly 5 includes leveling groove plates 501 installed on both sides of the upper mold assembly 4. Insertion pins 502 are rotatably installed inside the two leveling groove plates 501, and protective strips 503 are installed on the two insertion pins 502. A motor 504 is installed on one of the leveling groove plates 501 to rotate and adjust the protective strip 503 to be positioned below the upper mold assembly 4. When the hydraulic assembly 3 moves the upper mold assembly 4 and its internal steel barrel upwards and disengages from the mold base 1, the motor 504, in conjunction with the insertion pins 502, rotates the protective strip 503 downwards by at least 90°. This adjusts the horizontally arranged protective strip 503 on the side of the upper mold assembly 4 so that its main body is positioned below the upper mold assembly 4, thus forming a protective barrier below the steel barrel inside the upper mold assembly 4, preventing the steel barrel from falling directly downwards when the clamping force is unstable.

[0022] In order to effectively remove the stamped steel barrel from the mold base 1, such as Figure 1 and Figure 2 As shown, the upper mold assembly 4 includes an outer mold kit 401 positioned above the center of the mold base 1. An arc-shaped plate 402 is fitted into the inner wall of the outer mold kit 401. An electric push rod 403 mounted on the outer surface of the outer mold kit 401 causes the steel drum to be squeezed on both sides when it is lifted upward away from the mold base 1. The hydraulic assembly 3 includes a top seat 301 fixedly mounted on four guide pillars 2. Two hydraulic systems 302 arranged side by side are mounted on the top seat 301. The extension of the electric push rod 403 generates a set amount of squeezing force on both sides of the steel drum through the arc-shaped plate 402. As the hydraulic systems 302 return to their original position and move the outer mold kit 401 upward, the clamped steel drum also moves upward, thereby achieving separation from the mold base 1.

[0023] like Figure 2 and Figure 3 As shown, a lower pressure plate 303, whose top is connected to the free end of the hydraulic system 302, is slidably mounted on four guide pillars 2. An insertion block 3031 is installed in the center of the bottom surface of the lower pressure plate 303. Two parallel mating blocks 4011 are installed on the top of the outer mold assembly 401, with the distance between the two mating blocks 4011 matching the thickness of the insertion block 3031. A locking structure 4012, which passes through the insertion block 3031 and the other mating block 4011 sequentially, is installed on one of the mating blocks 4011. The upper mold assembly 4 and the hydraulic assembly 3 are in a detachable assembly state. Assembly is completed by locking the mating block 4011 on the outer mold assembly 401 and the insertion block 3031 at the bottom of the lower pressure plate 303 using the locking structure 4012. Similarly, removing the locking structure 4012 allows for the replacement of outer mold assemblies 401 with different configurations.

[0024] like Figure 4As shown, the mold base 1 includes a load-bearing base 101. A slot 1011 is formed in the middle of the top surface of the load-bearing base 101. An inner mold assembly 102 adapted to the outer mold assembly 401 is installed on the bottom wall of the slot 1011. Several elastic structures 103 are installed on the bottom wall of the slot 1011. An annular plate 104 surrounding the outer surface of the inner mold assembly 102 is installed on the top of the elastic structures 103. During the process of the hydraulic system 302 advancing downward and the mold assembly 4 pressing the steel placed on the inner mold assembly 102, the annular plate 104 is also subjected to a compressive force in the latter half of the process, causing the elastic structures 103 to contract downward so that the outer mold assembly 401, the inner mold assembly 102, and the steel can fit together completely. After the steel is stamped into a steel drum, the hydraulic system 302 contracts upward, removing the extrusion pressure on the annular plate 104 and the elastic structure 103. When the elastic structure 103 returns to its original shape, it can generate an upward pushing force on the annular plate 104. Based on this, it also generates an upward pushing force on the steel drum, preventing the steel drum from being firmly fitted onto the outer surface of the inner mold kit 102.
