A hydraulic press device for producing metal trash cans

Abstract

This invention relates to the field of hydraulic press technology and discloses a hydraulic press device for producing metal trash cans, including a main body with four positioning rods fixedly connected to the top of the main body. When the arc-shaped plate continues to press the top of the can and rotates, it provides guiding friction to the can body. At this time, the metal area at the top of the can body is bent and shaped as the arc-shaped plate rotates. When the can body pushes the arc-shaped plate upwards, the arc-shaped plate pre-presses the metal at the top of the can body. Then, when the arc-shaped plate drives the metal of the can body to rotate and curl the edge, it enhances the curling force while reducing the likelihood of cracks appearing in the metal body during the curling process. By assisting in increasing the curling strength of the metal body, the arc-shaped plate further improves the integrity of the curling angle and increases the curling efficiency.

Description

Technical Field

[0001] This invention relates to the field of hydraulic press technology, specifically to a hydraulic press device for producing metal trash cans. Background Technology

[0002] A hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to achieve various processes. A hydraulic press generally consists of three parts: the machine itself, the power system, and the hydraulic control system. It uses the static pressure of liquid to process metal, plastic, rubber, wood, powder and other products. It is often used in pressing and pressing forming processes, such as: forging, stamping, cold extrusion, straightening, bending, flanging, deep drawing of thin plates, powder metallurgy, and press fitting.

[0003] Metal trash cans require a hydraulic press to form the edges during production. When forming the edges of a round trash can, a mold with a curved cavity is typically used. The metal at the edge of the can is compressed and bent within the mold cavity, achieving the purpose of edge curling. However, due to the curvature of the mold cavity, the metal at the edge can only bend along the curve of the cavity. This compression can easily lead to cracks and incomplete curling angles at the edge, affecting the integrity and efficiency of the finished product. Summary of the Invention

[0004] The purpose of this invention is to provide a hydraulic press device for producing metal trash cans, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a hydraulic press device for producing metal trash cans, comprising a main body, four positioning rods fixedly connected to the top of the main body, and further comprising:

[0007] A rotating mechanism is installed on the top of the main body to prevent incomplete edge curling during the edge curling process.

[0008] An auxiliary mechanism is installed at the bottom of the rotating mechanism to prevent deformation of the barrel body when the rotating mechanism is working.

[0009] Furthermore, the four positioning rods are fixedly connected to a top plate at the ends furthest from the main body, and also include:

[0010] Hydraulic components are installed on the top of the top plate;

[0011] The elastic component is installed on the top of the main body.

[0012] Furthermore, the rotating mechanism includes an upper mold disposed at the bottom of the hydraulic assembly, and the rotating mechanism also includes:

[0013] The sliding component is installed on the inner wall of the upper mold;

[0014] A rotating assembly is mounted on the side wall of the sliding assembly.

[0015] Furthermore, the auxiliary mechanism includes a rotating frame disposed at the bottom of the sliding component, and the auxiliary mechanism also includes:

[0016] Deformation component, which is installed on the side wall of the rotating frame.

[0017] Furthermore, a hydraulic cylinder is bolted to the top of the top plate, and the output end of the hydraulic cylinder slides through to the bottom outer wall of the top plate. A bearing plate is bolted to the output end of the hydraulic cylinder.

[0018] The support plate is slidably connected to the outer surface of the four positioning rods, and the bottom of the support plate is bolted to the mounting bracket.

[0019] Furthermore, the elastic component includes a fixing frame bolted to the top of the main body, two expansion plates slidably connected to the top of the fixing frame, and a spring frame slidably connected between the two expansion plates;

[0020] The elastic end of the spring frame is fixedly connected to the side wall of the main body.

[0021] Furthermore, the upper mold is fixedly connected to the bottom of the mounting frame, and several right-angled blocks are fixedly connected to the top outer wall of the upper mold;

[0022] The sliding assembly includes several tension springs fixedly connected to the inner wall of the top of the upper mold. A rotating frame is fixedly connected to the bottom of the tension springs, and an auxiliary rod is fixedly connected between two rotating frames.

[0023] Arc-shaped rods are fixedly connected to both the left and right sides of the rotating frame.

[0024] Furthermore, the rotating assembly includes an arc-shaped plate slidably connected to the outer surface of the arc-shaped rod, and a limiting spring is fixedly connected between the two arc-shaped plates;

[0025] Among them, a right-angled block two is slidably connected between the two arc-shaped plates, and an arc-shaped strip is fixedly connected to the bottom of the right-angled block two.

[0026] Furthermore, the rotating frame is rotatably connected inside the rotating bracket;

[0027] The deformation assembly includes an elastic plate fixedly connected to the side wall of the rotating frame, with one end of the elastic plate away from the rotating frame fixedly connected to the side wall of the rotating frame.

[0028] Furthermore, two rectangular grooves are formed in the sidewall of the elastic plate;

[0029] The rectangular groove is internally slidably connected by H-frame 1, and H-frame 2 is rotatably connected between the two H-frames 1. A bending spring is fixedly connected between the two H-frames 1.

[0030] The present invention has the following beneficial effects:

[0031] 1. In this invention, when the arc-shaped plate continues to press the top of the barrel and rotates, the arc-shaped plate will provide guiding friction to the barrel. At this time, the metal area at the top of the barrel will be bent and shaped as the arc-shaped plate rotates. When the barrel pushes the arc-shaped plate to slide upward, the arc-shaped plate will pre-press the metal at the top of the barrel. Then, when the arc-shaped plate drives the barrel metal to rotate and curl the edge, the arc-shaped plate can enhance the curling force while reducing the occurrence of cracks in the barrel metal during the curling process. By assisting in promoting the curling strength of the barrel metal, the arc-shaped plate further improves the integrity of the curling angle and improves the curling efficiency.

[0032] 2. In this invention, when the rotating frame rotates downward, it also pushes the inner wall of the barrel through the elastic plate, causing the deformed H-frame to contact the barrel at the bottom of the barrel's edge-rolling area. By blocking the inner wall of the barrel through multiple elastic plates, the pressure on the top of the barrel and during the rolling process can be reduced, which can lead to dents or twisting deformation of the barrel's side wall. This would affect the subsequent edge-rolling efficiency and also easily cause deviations in the roundness of the barrel during production, thus improving the production quality and surface integrity of the barrel.

[0033] 3. This invention enhances the contact strength and stability between the curved plate and the barrel body during rotation and edge rolling by the drag force generated by the curved plate. This reduces slippage between the curved plate and the barrel body during rotation and edge rolling, ensuring the edge rolling strength and continuity of the curved plate during edge rolling. This further improves the processing strength of the hydraulic equipment during barrel production and the precision and efficiency of subsequent edge rolling.

[0034] 4. In this invention, when the arc-shaped plate slides, it slides on the top of the barrel. When the arc-shaped plate slides, it can reduce the occurrence of uneven edge curling and local bulges in areas of the barrel without the arc-shaped plate during the edge curling process. At the same time, when the right-angle block two drives the arc-shaped strip to slide, the sliding of the arc-shaped strip can compress and shrink the barrel after edge curling, thereby reducing the occurrence of springback and opening after edge curling. This further improves the consistency and uniformity of the barrel during the edge curling process, while also improving the integrity of the edge curled part and increasing the production efficiency of the barrel.

[0035] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Please see Figure 1 - Figure 11 As shown, the present invention is a hydraulic press device for producing metal trash cans, including a main body 1, four positioning rods fixedly connected to the top of the main body 1, and further including:

[0052] Rotating mechanism 2 is installed on the top of the main body 1 to prevent incomplete edge curling angle when curling the edge of the barrel body;

[0053] Auxiliary mechanism 3 is installed at the bottom of rotating mechanism 2 to prevent deformation of the barrel body when rotating mechanism 2 is working.

[0054] The top plate 101 is fixedly connected to one end of the four positioning rods away from the main body 1, and the system also includes:

[0055] Hydraulic assembly 11 is installed on the top of top plate 101;

[0056] Elastic component 12 is installed on the top of the main body 1.

[0057] The rotating mechanism 2 includes an upper mold 201 disposed at the bottom of the hydraulic assembly 11, and the rotating mechanism 2 also includes:

[0058] Sliding component 21 is installed on the inner wall of the upper mold 201;

[0059] Rotating component 22 is mounted on the side wall of sliding component 21.

[0060] The auxiliary mechanism 3 includes a rotating frame 301 disposed at the bottom of the sliding component 21, and the auxiliary mechanism 3 also includes:

[0061] Deformation component 31 is installed on the side wall of rotating frame 301.

[0062] A hydraulic cylinder 111 is bolted to the top of the top plate 101. The output end of the hydraulic cylinder 111 slides through to the bottom outer wall of the top plate 101. A bearing plate 112 is bolted to the output end of the hydraulic cylinder 111.

[0063] The bearing plate 112 is slidably connected to the outer surface of the four positioning rods. The bottom of the bearing plate 112 is bolted to the mounting bracket 113. When the hydraulic cylinder 111 works, it will push the bearing plate 112 and the mounting bracket 113 to slide downward. When the mounting bracket 113 slides downward, it will cause the upper mold 201 and the multiple arc plates 221 inside the upper mold 201 to squeeze the metal at the top of the barrel.

[0064] The elastic component 12 includes a fixing frame 121 bolted to the top of the main body 1, two expansion plates 122 slidably connected to the top of the fixing frame 121, and a spring frame 123 slidably connected between the two expansion plates 122.

[0065] The elastic end of the spring frame 123 is fixedly connected to the side wall of the main body 1.

[0066] The upper mold 201 is fixedly connected to the bottom of the mounting bracket 113, and several right-angled blocks 202 are fixedly connected to the top outer wall of the upper mold 201;

[0067] The sliding assembly 21 includes several tension springs 211 fixedly connected to the inner wall of the top of the upper mold 201. A rotating frame 212 is fixedly connected to the bottom of the tension springs 211, and an auxiliary rod is fixedly connected between two rotating frames 212.

[0068] Arc-shaped rods 213 are fixedly connected to the left and right sides of the rotating frame 212. When the upward sliding arc plate 221 slides to the bottom of the right-angle block 202 and contacts the right-angle block 202, the continued downward movement of the upper mold 201 will cause the arc plate 221 to continue to slide upward under the push of the barrel body.

[0069] The rotating assembly 22 includes an arc plate 221 that is slidably connected to the outer surface of the arc rod 213, and a limiting spring is fixedly connected between the two arc plates 221;

[0070] Among them, a right-angled block 222 is slidably connected between the two arc-shaped plates 221, and an arc-shaped strip 223 is fixedly connected to the bottom of the right-angled block 222. When the metal of the barrel pushes the arc-shaped plate 221 to slide upward, the sliding of the arc-shaped plate 221 will drive the rotating frame 301 to slide synchronously through the rotating frame 212.

[0071] The rotating frame 301 is rotatably connected to the inside of the rotating bracket 212;

[0072] The deformation component 31 includes an elastic plate 311 fixedly connected to the side wall of the rotating frame 301, and the end of the elastic plate 311 away from the rotating frame 301 is fixedly connected to the side wall of the rotating frame 212.

[0073] Two rectangular grooves are provided on the side wall of the elastic plate 311;

[0074] The rectangular groove is internally slidably connected to H-frame 312, and H-frame 313 is rotatably connected between the two H-frames 312. A bending spring is fixedly connected between the two H-frames 312. When the elastic plate 311 deforms during the rotation of the rotating frame 301, the curvature of the deformed elastic plate 311 will gradually extend. At the same time, when the elastic plate 311 deforms, the two H-frames 312 will move closer to each other under the elastic contraction of the bending spring between them.

[0075] In use, the barrel to be processed is first placed on the surface of the two expansion plates 122 and the bottom of the barrel is in contact with the top of the fixing frame 121. Then, the operator starts the hydraulic cylinder 111. When the hydraulic cylinder 111 works, it pushes the bearing plate 112 and the mounting frame 113 to slide downward. When the mounting frame 113 slides downward, it causes the upper mold 201 and the multiple arc plates 221 inside the upper mold 201 to squeeze the metal at the top of the barrel. When the top of the barrel is squeezed by the arc plates 221, the metal at the top of the barrel will be bent and rolled under the pressure of the multiple arc plates 221, thereby achieving the purpose of rolling the edge during the production of the barrel.

[0076] When the mounting bracket 113 drives multiple arc-shaped plates 221 to slide downwards and press the barrel body through the upper mold 201, the arc-shaped plates 221 will slide upwards within the upper mold 201 and compress the tension spring 211 under the reaction force of pressing the barrel body. At this time, the arc-shaped plates 221 will apply an initial pressure to the barrel body. When the upward-sliding arc-shaped plates 221 slide to the bottom of the right-angle block 202 and contact the right-angle block 202, the continued downward movement of the upper mold 201 will cause the arc-shaped plates 221 to continue sliding upwards under the push of the barrel body. At this time, the arc-shaped plates 221 will rotate under the guidance of the inclined surface of the right-angle block 202 under the push of the barrel body. Due to the setting of the inclined surface of the right-angle block 202, the arc-shaped plates 221 will generate a rotational torque around the arc-shaped rod 213 while sliding upwards under the constraint of the inclined surface of the right-angle block 202, presenting as follows. Figure 10In the state of position G, when the arc plate 221 continues to press the top of the barrel and rotates, the arc plate 221 will provide a guiding friction to the barrel. At this time, the metal area at the top of the barrel will be bent and shaped as the arc plate 221 rotates. When the barrel pushes the arc plate 221 to slide upward, the arc plate 221 will pre-press the metal at the top of the barrel. Then, when the arc plate 221 drives the barrel metal to rotate and curl, the arc plate 221 can enhance the curling force while reducing the occurrence of cracks in the barrel metal during the curling process. By assisting in promoting the curling strength of the barrel metal, the arc plate 221 can further improve the integrity of the curling angle and improve the curling efficiency.

[0077] When the metal of the barrel pushes the arc-shaped plate 221 upward, the sliding of the arc-shaped plate 221 will drive the rotating frame 301 to slide synchronously through the rotating frame 212. When the rotating frame 301 slides with the rotating frame 212, the rotating frame 301 will rotate downward under the obstruction of the edge of the upper mold 201. When the rotating frame 301 rotates downward, it will push the bottom of the elastic plate 311 and generate a downward pulling force on its bottom. At the same time, when the rotating frame 301 rotates downward, the rotating frame 301 will also exert a force on the inner wall of the barrel through the elastic plate 311. The H-frame 312 is pushed and deformed to contact the barrel body at the bottom of the edge-rolling area. The multiple elastic plates 311 block the inner wall of the barrel body, which can reduce the pressure on the top of the barrel body or the localized force concentration when the curved plate 221 squeezes the barrel body. This can prevent the barrel body side wall from denting or twisting, which would affect the subsequent edge-rolling efficiency and also easily cause the barrel body's roundness to deviate during the production process. This improves the production quality and surface integrity of the barrel body.

[0078] When the elastic plate 311 deforms during the rotation of the rotating frame 301, its curvature gradually extends. Simultaneously, as the elastic plate 311 deforms, the two H-frames 312 move closer together under the elastic contraction of the bending springs between them. When the two H-frames 312 approach each other, they push the second H-frame 313, causing its side away from the first H-frame 312 to contact the inner wall of the upper mold 201. At this point, the moved second H-frame 313 and the deformed elastic plate 311 become stuck between the inner wall of the barrel and the inner wall of the upper mold 201, creating a large gap between them. Friction also generates a downward drag force on the curved plate 221 during the edge-rolling process of the barrel. This drag force enhances the contact strength and stability between the curved plate 221 and the barrel body when the plate rotates and rolls the edge. This reduces the possibility of slippage between the curved plate 221 and the barrel body during the rotation and edge-rolling process, ensuring the edge-rolling strength and continuity of the curved plate 221. This further improves the processing strength of the hydraulic equipment during barrel production and the precision and efficiency of subsequent edge-rolling.

[0079] When the curved plate 221 slides upward and contacts the bottom of the right-angle block 202 and rotates, the rotation of the curved plate 221 will cause the right-angle block 222 to rotate synchronously. Since the right-angle block 222 contacts the inclined surface of the right-angle block 202 when the curved plate 221 contacts the bottom of the right-angle block 202, and then the curved plate 221 rotates during the compression of the barrel, the rotation of the curved plate 221 will cause the right-angle block 222 to drive the curved strip 223 to slide between the two curved plates 221. When the right-angle block 222 slides, it will compress the sidewall between the two curved plates 221. When the sidewall of the two curved plates 221 on opposite sides is pushed by the right-angle block 222, the two... The arc plates 221 on the arc rod 213 will slide away from each other. When the arc plates 221 slide, they will slide on the top of the barrel. When the arc plates 221 slide, they can reduce the occurrence of local bulges in the area of ​​the top of the barrel without arc plates 221 during the edge rolling process. At the same time, when the right-angle block 222 drives the arc strip 223 to slide, the sliding of the arc strip 223 can compress the barrel after edge rolling, thereby reducing the occurrence of springback and opening after edge rolling. This further improves the consistency and uniformity of the barrel during the edge rolling process, and also improves the integrity after edge rolling, thus improving the production efficiency of the barrel.
