Description

Technical Field

[0001] This utility model relates to the field of pressure molding equipment technology, and in particular to a press that automatically adjusts the ellipticity of a rubber skeleton. Background Technology

[0002] A press is a sophisticated and versatile press with a wide range of applications and high production efficiency. Presses can be widely used in cutting, punching, blanking, bending, riveting and forming processes. They process metal parts by applying strong pressure to cause plastic deformation or fracture.

[0003] As a key supporting structure for rubber products, the shape accuracy, especially the ellipticity, plays a decisive role in the performance and quality of rubber products. For example, in automobile tire production, the accuracy of the ellipticity of the rubber skeleton directly affects the tire's balance and driving stability. In the manufacturing of sealing rubber parts, deviations in ellipticity can lead to poor sealing performance and leakage problems.

[0004] The traditional method for adjusting the ellipticity of a rubber skeleton involves the operator rotating the skeleton on a roundness dial and then manually tapping the raised areas to adjust the ellipticity. This method is not highly automated, involves high labor intensity for the operator, has low production efficiency, increases enterprise costs, and causes inconvenience for the operator. Existing technology uses a specific mold to compress the rubber skeleton to form a specific ellipticity. However, in actual use, repeated mold closing causes wear, and the pressure during compression becomes unstable, resulting in defects that are not visible to the naked eye, thus causing quality problems in the produced rubber skeletons.

[0042] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an automatic rubber skeleton ellipticity adjustment press, including a support platform 1, which serves as the basic support structure for the entire press, used to support and stabilize the various components of the press. Columns 4 are fixedly connected to the four corners of the top of the support platform 1, connecting the support platform 1 to the top plate 5, providing vertical support for the entire press. The tops of the multiple columns 4 are fixedly connected to the top plate 5, providing an installation platform for the shaping mechanism 2.

A storage component 6 is provided on the inner wall of the support platform 1 for storing tools and parts related to the operation and maintenance of the press, facilitating access and management. A positioning component 7 is provided at the bottom of the support platform 1 to determine the accurate position of the press in the work area, ensuring the stability and processing accuracy of the press during operation. The shaping mechanism 2 includes a hydraulic rod 201, which drives the mounting plate 202 to move up and down through telescopic movement, thereby applying pressure to the rubber skeleton. The top of the hydraulic rod 201 is fixedly connected to the top of the support platform 1. A mounting plate 202 is fixedly connected to the bottom center of the top plate 5. The bottom end of the hydraulic rod 201 is fixedly connected to the mounting plate 203, which is used to connect the hydraulic rod 201 to the mounting plate 203 and the punch 204. Mounting plates 203 are fixedly connected to the left and right sides of the outer wall of the mounting plate 202. The bottom of the mounting plate 203 is provided with a punch 204, and the top of the support platform 1 is provided with a concave mold 205. The punch 204 and the concave mold 205 cooperate to apply pressure to the rubber skeleton placed in the concave mold 205. This causes plastic deformation to achieve the required ellipticity. Bolts 207 are threaded around the outer wall of the die 205 to fix the die 205 to the support table 1, ensuring the stability of the die 205 during operation. The bottom ends of multiple bolts 207 are threaded to the support table 1. Multiple pressure sensors 206 are fixedly connected around the top of the die 205 to monitor the pressure applied by the punch 204 to the rubber skeleton in real time, providing pressure data to the operator for precise control of the molding process.

[0043] Specifically, the support platform 1, as a basic component, provides stable support for the entire press. The columns 4, fixedly connected to the four corners of its top, extend upwards and are fixed to the top plate 5, forming the frame structure of the press and ensuring the stable installation of each component. The top plate 5 supports the shaping mechanism 2 and provides mounting points for the hydraulic rod 201. The top of the hydraulic rod 201 is connected to the middle of the bottom of the top plate 5, and the lower end is connected to the mounting plate 202. Through telescopic movement, it drives the mounting plate 202 to move up and down. The left and right sides of the mounting plate 202 are connected to mounting plates 203, allowing the punch 204 to be fixed to the bottom of the mounting plate 203 and move synchronously with the mounting plate 202. The die 205 is used to extrude the rubber skeleton. The die 205 is placed on the top of the support platform 1 and fixed to the support platform 1 by bolts 207. This provides molding space for the rubber skeleton. The pressure sensor 206 is fixed around the top of the die 205 to monitor the pressure data when the punch 204 extrudes the rubber skeleton in real time. The quick-installation mechanism 3 is set on the outer wall of the molding mechanism 2 to facilitate quick installation of the punch 204. The storage component 6 is located on the inner wall of the support platform 1 and can store tools or parts. The positioning component 7 is at the bottom of the support platform 1 and is used to accurately position the press. All components work together to achieve automatic adjustment of the ellipticity of the rubber skeleton.

[0044] Reference Figure 3 and Figure 4The quick-installation mechanism 3 includes two sliders 301, which are fixedly connected to the front and rear sides of the top of the punch 204, respectively. These sliders provide a sliding base for the connection between the punch 204 and the mounting plate 202, and participate in the positioning and fixing of the punch 204. A U-shaped rod 302 is slidably connected to the top right end of the mounting plate 202, allowing it to slide on the mounting plate 202 and adjust the position of the insert block 303. Insert blocks 303 are fixedly connected to the opposite sides of the U-shaped rod 302 for insertion into the slots 308 of the sliders 301, thereby fixing the sliders 301 and the punch 204. A fixing seat 304 is fixedly connected to the top of the right mounting plate 203, providing a fixed support point for the springs 305 and the pull rod 306, ensuring their proper functioning. Multiple springs 305 are fixedly connected to the right side of the outer wall of the U-shaped rod 302, using their elastic force to push the U-shaped rod 302 to the left, causing the insert block 303 to insert into the slot 308, thus automatically fixing the punch 204. The right ends of multiple springs 305 are fixedly connected to the left side of the fixed base 304. A pull rod 306 is fixedly connected to the middle of the right end of the U-shaped rod 302, allowing the operator to manually pull the U-shaped rod 302 to overcome the elastic force of the springs 305, causing the insert block 303 to disengage from the slot 308, facilitating the disassembly of the punch 204. The right end of the pull rod 306 penetrates the fixed base 304, ensuring that the pull rod 306 can freely pull the U-shaped rod 302 while providing guidance and limiting for the movement of the pull rod 306. The top front and rear sides of the mounting plate 202 are provided with sliding grooves 307, and the middle of the two sliders 301 is provided with slots 308. The slots 308 match the inserts 303 and are used to insert the inserts 303 to achieve a fixed connection between the punch 204 and the mounting plate 202. The two sliders 301 are slidably connected to the corresponding sliding grooves 307 respectively, so that the punch 204 can be accurately installed on the mounting plate 202 along the predetermined track. The multiple inserts 303 are slidably connected to the corresponding slots 308 respectively.

[0045] Specifically, two sliders 301 are fixed to the front and rear sides of the top of the punch 204, and are slidably connected to the grooves 307 opened on the front and rear sides of the top of the mounting plate 202, providing guidance and initial positioning for the installation of the punch 204, so that the punch 204 can be accurately installed in place along the grooves 307. The U-shaped rod 302 is slidably connected to the right end of the top of the mounting plate 202, and the insert block 303 fixed on the opposite side corresponds to the slot 308 opened in the middle of the slider 301. The fixing seat 304 on the top of the right mounting plate 203 provides a fixed support point for the spring 305 and the pull rod 306. Multiple springs 305 are connected to the U-shaped rod 306. The outer right side of the 2nd outer wall and the left side of the fixing seat 304 play a key role in installing the punch 204 by utilizing their own elastic force. The pull rod 306 is fixed to the middle of the right end of the U-shaped rod 302 and passes through the fixing seat 304, which makes it convenient for the operator to manually pull the U-shaped rod 302. The compression spring 305 causes the insert block 303 to disengage from the slot 308, so as to install or remove the punch 204. When the pull rod 306 is released, the spring 305 returns to its original position and pushes the U-shaped rod 302, which drives the insert block 303 to insert into the slot 308, so as to achieve a firm fixation of the punch 204. The coordinated action of each component simplifies the installation process of the punch 204 and improves work efficiency.

[0046] Reference Figure 1 , Figure 2 and Figure 5 The storage component 6 includes a storage box 601, the bottom of which is slidably connected to the bottom of the inner wall of the support platform 1. It is used to store tools and parts related to the operation and maintenance of the press. Multiple partitions 602 are fixedly connected to the front and rear sides of the inner wall of the storage box 601 to divide the internal space, allowing different types of tools or parts to be stored separately for easy organization and retrieval. Protective doors 603 are rotatably connected to the left and right sides of the front end of the outer wall of the support platform 1, and can be opened or closed to protect the items inside the storage box 601 from damage. External environmental influences or accidental drops; the positioning component 7 includes multiple positioning feet 701 to achieve precise positioning of the press in the work area. The outer walls of the multiple positioning feet 701 are fixedly connected to the four corners of the bottom of the support platform 1. The middle of the outer wall of each of the multiple positioning feet 701 is provided with a positioning hole 702. By inserting the positioning component, the press can be accurately aligned with the preset position of the work area. The right side of the outer wall of the support platform 1 is fixedly connected to a controller 8, which is used to regulate the working parameters and operating status of the press. The controller 8 is electrically connected to the hydraulic rod 201.

[0047] Specifically, in the storage component 6, the bottom of the storage box 601 is slidably connected to the bottom of the inner wall of the support platform 1, making it easy to pull out or push in, facilitating the storage and retrieval of tools. Multiple partitions 602 on the front and back sides of the inner wall can classify and place tools, improving the orderliness of storage. The protective door 603, which is rotatably connected to the left and right sides of the front end of the outer wall of the support platform 1, can protect the tools in the storage box 601 from external interference and prevent tools from falling or being damaged. In the positioning component 7, multiple positioning feet 701 are fixed at the four corners of the bottom of the support platform 1, providing stable support for the press. The positioning hole 702 opened in the middle of its outer wall can be used to accurately position the press in the work area by inserting positioning pins, etc., to prevent displacement from affecting the working accuracy. The controller 8 on the right side of the outer wall of the support platform 1 is electrically connected to the hydraulic rod 201. The operator can conveniently control the extension and retraction of the hydraulic rod 201 through the controller 8, thereby accurately controlling the pressure applied to the rubber skeleton by the shaping mechanism 2, realizing effective control of the process of adjusting the ellipticity of the rubber skeleton.

[0048] Reference Figure 1 , Figure 2 and Figure 3 A support frame 9 is fixedly connected to the top of the top plate 5 to provide a stable support structure for the display screen 10, ensuring that the display screen 10 maintains a stable position during the operation of the press. The display screen 10 is fixedly connected to the front of the outer wall of the support frame 9 to intuitively display relevant data information during the operation of the press. Two guide rods 11 are fixedly connected to the top left and right sides of the support platform 1 to provide a precise guide path for the movement of the mounting plate 203, ensuring the stability and accuracy of the mounting plate 203 during the up and down movement. The two mounting plates 203 are slidably connected to the corresponding guide rods 11, so that the mounting plate 203 can move smoothly along the guide rods 11, thereby ensuring the positional accuracy of the punch 204 when shaping the rubber skeleton. Slide bars 12 are fixedly connected to the bottom left and right sides of the storage box 601, and slide rails 13 are opened on the bottom left and right sides of the inner wall of the support platform 1. The two slide bars 12 are slidably connected to the corresponding slide rails 13, so that the storage box 601 can slide smoothly in the support platform 1.

[0049] Specifically, the support frame 9 provides a stable mounting position for the display screen 10, enabling the display screen 10 to clearly display the data information of the pressure sensor 206, which is convenient for operators to view in real time. The guide rods 11 on the top left and right sides of the support platform 1 are slidably connected to the mounting plate 203, ensuring that the mounting plate 203 and the connected punch 204 move vertically and smoothly under the drive of the hydraulic rod 201, improving the shaping accuracy. The slide bar 12 at the bottom of the storage box 601 is slidably connected to the slide rail 13 at the bottom of the inner wall of the support platform 1, allowing the storage box 601 to enter and exit the support platform 1 more smoothly, facilitating the storage and retrieval of tools and improving the overall operational convenience of the equipment.

[0050] Reference Figure 1 , Figure 2 and Figure 4 Two reinforcing rods 14 are fixedly connected to the top of the outer wall of each of the multiple columns 4. The top of each reinforcing rod 14 is fixedly connected to the top plate 5, which enhances the connection strength between the columns 4 and the top plate 5. By increasing the support structure, the stability of the entire press frame is improved. Limiting blocks 15 are fixedly connected to the bottom of each of the two insert blocks 303. Limiting grooves 16 are opened on the front and rear sides of the top of the mounting plate 202. The two limiting blocks 15 are slidably connected to the corresponding limiting grooves 16, which not only ensures the smooth sliding of the insert blocks 303 on the mounting plate 202, but also precisely controls the position of the insert blocks 303, thereby ensuring the accuracy and stability of the punch 204 installation.

[0051] Specifically, the reinforcing rods 14 on the multiple columns 4 are connected to the top plate 5 to enhance the structural stability between the columns 4 and the top plate 5 and improve the overall strength of the press. The bottom limiting block 15 of the insert block 303 is slidably connected to the upper limit groove 16 of the mounting plate 202 to limit the movement range of the insert block 303, ensure that the insert block 303 and the slot 308 in the quick-installation mechanism 3 cooperate stably, and ensure that the punch 204 is firmly installed.

[0052] Working principle: First, the rubber skeleton to be processed is placed stably in the groove of the die 205. The die 205 is threadedly connected to the support table 1 by bolts 207 around its perimeter to ensure its stability. Next, the hydraulic rod 201 is activated. The top of the hydraulic rod 201 is fixed to the middle of the bottom end of the top plate 5. After activation, it drives the mounting plate 202 to move downward. It should be noted that although the specific installation of the guide rod 11 is not mentioned above, in actual operation, the guide rod 11 plays a key guiding role, enabling the punch 204 to move smoothly downward along the predetermined trajectory under the drive of the mounting plate 202. As the punch 204 moves downward, it closely cooperates with the die 205, applying pressure to the rubber skeleton placed in the die 205, causing the rubber skeleton to gradually... The material is compressed into an elliptical shape. During this process, multiple pressure sensors 206 distributed around the top of the die 205 play an important role. They are in contact with the bottom of the punch 204 and receive the downward pressure applied by the punch 204 in real time. The pressure sensors 206 transmit the received pressure values ​​to the display screen 10. The operator can clearly observe the pressure values ​​applied at various points on the bottom of the punch 204 through the display screen 10. By comparing whether the pressure received by each part is consistent, the operator can judge whether the pressure of each part of the punch 204 is equal during the downward pressing process. If the pressure of each part is uniform, it can ensure that the rubber skeleton is subjected to balanced force during the molding process, thereby effectively controlling the quality of the rubber skeleton and avoiding quality problems such as ellipticity deviation caused by uneven pressure.

[0053] Furthermore, when installing the punch 204, first pull the tie rod 306 to the right. Since the tie rod 306 is fixedly connected to the middle of the right end of the U-shaped rod 302, the movement of the tie rod 306 will cause the U-shaped rod 302 to move to the right as well. During this process, the multiple springs 305 connected to the right side of the outer wall of the U-shaped rod 302 are compressed, generating elastic deformation and storing elastic potential energy. Next, align the slider 301 on the punch 204 with the sliding grooves 307 opened on the front and rear sides of the top of the mounting plate 202. At this time, the slot 308 opened in the middle of the slider 301 corresponds to the sliding groove 307. Then, release the... The previously compressed spring 305, due to its elastic restoring force, needs to return to its original shape. During this process, the spring 305 pushes the U-shaped rod 302 to the left, causing the insert block 303, which is fixedly connected to the opposite side of the U-shaped rod 302, to be inserted into the slot 308 in the middle of the corresponding slider 301. Through the sliding connection between the insert block 303 and the slot 308, the slider 301 is fixed, thereby quickly completing the installation of the punch 204. This design simplifies the installation process of the punch 204, saves installation time, and improves work efficiency.
