Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to an error-proofing device for stamping forming dies for automotive parts. Background Technology

[0002] Stamping refers to a processing method that uses a press and dies to apply external force to sheet metal, strip, tube, and profile materials, causing plastic deformation or separation to obtain workpieces (stamped parts) of the required shape and size. An existing patent, CN221362259U, describes a stamping die, including a stamping die frame, a pre-forming die, and a secondary forming die, each respectively mounted on the stamping die frame. Positioning structures are located at the same position between the upper and lower dies of both the pre-forming and secondary forming dies. The positioning structures on the pre-forming die can stamp out a positioning shape on the bipolar plate. The positioning shape, in conjunction with the positioning structures on the secondary forming die, can position the bipolar plate on the secondary forming die. This invention's stamping die can form a positioning shape on the bipolar plate during pre-forming stamping; during secondary forming, it can easily place the bipolar plate in the correct position on the secondary forming die, facilitating the positioning of the bipolar plate during secondary stamping and ensuring the consistency of the bipolar plate's position during pre-forming and secondary forming, thus guaranteeing the product's forming quality.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: When existing forming dies are used for stamping operations, due to the limitations of different manual placement positions, incorrect placement of workpieces can easily lead to incorrect contact when the stamping die moves downwards, resulting in damage to the workpiece and the die body, and causing economic losses. Therefore, we propose an error-proofing device for automotive parts stamping dies to solve the above-mentioned problems. Utility Model Content

[0023] 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.

[0024] Please see Figures 1-6This utility model provides a technical solution: an error prevention device for stamping forming molds of automotive parts, including a mold mechanism 1, a guide rod assembly 1014 fixedly connected to the top surface of the mold mechanism 1, and a moving mechanism 2 sleeved on the outside of the guide rod assembly 1014;

[0025] The moving mechanism 2 has a through hole inside, which is a guide hole 201. There are four guide holes 201, which are respectively opened at the four corners inside the moving mechanism 2. A U-shaped guide frame assembly 2012 with a one-way opening at the bottom end is fixedly connected to the top surface of the moving mechanism 2. A stamping assembly 2011 is fixedly connected to the bottom surface of the moving mechanism 2. A top rod assembly 2014 is inserted into the guide frame assembly 2012. A contact switch 2013 is fixedly connected to the bottom surface of the transverse member in the guide frame assembly 2012. A baffle assembly 2015 is fixedly connected to the outside of the top rod assembly 2014. The baffle assembly 2015 is located directly below the contact switch 2013. A top plate assembly 2016 is fixedly connected to the top surface of the top rod assembly 2014. A return spring 2017 is fixedly connected to the bottom surface of the top plate assembly 2016. The bottom end of the return spring 2017 is fixedly connected to the top end of the guide frame assembly 2012.

[0026] The mold mechanism 1 and guide rod assembly 1014 provide support and guidance for the moving mechanism 2, enabling the moving mechanism 2 to move stably on the guide rod assembly 1014. The guide hole 201, guide frame assembly 2012, stamping assembly 2011, and other components of the moving mechanism 2 work together to ensure the accuracy of the stamping operation. The ejector rod assembly 2014, contact switch 2013, baffle plate assembly 2015, top plate assembly 2016, and return spring 2017 cooperate to monitor and control the stamping process, preventing damage to the mold and workpiece due to incorrect contact.

[0027] See Figure 1 , Figure 2 The top of the mold mechanism 1 is provided with a groove, which is the mold cavity assembly 101. The outer side of the mold mechanism 1 is fixedly connected with the mounting assembly 1011.

[0028] By providing space for placing the workpiece through the mold cavity assembly 101 at the top of the mold mechanism 1, and providing a connection point for the installation of the mold mechanism 1 through the mounting assembly 1011 on the outside, it is convenient to install the mold onto the stamping equipment and ensure the stability of the mold installation.

[0029] See Figure 4 , Figure 5 There are two mounting components 1011, which are fixedly connected to the left and right sides of the mold mechanism 1 respectively.

[0030] By fixing the two mounting components 1011 to the left and right sides of the mold mechanism 1 respectively, the stability of the connection between the mold mechanism 1 and the stamping equipment is increased, so that the mold can better withstand the impact force during the stamping process, reduce shaking and displacement, and ensure the accuracy of the stamping operation.

[0031] See Figure 1 , Figure 2 The two mounting components 1011 have two mounting slots 1012 arranged in a linear array inside, and the top of the mold mechanism 1 has a recessed hole, which is a positioning hole 1013.

[0032] The mounting slot 1012 inside the mounting component 1011 facilitates the installation of the mold mechanism 1 onto the stamping equipment using bolts or other connecting parts, enabling quick installation and disassembly; the positioning hole 1013 at the top of the mold mechanism 1 provides a reference for positioning the workpiece or other components, improving the accuracy of the stamping operation.

[0033] See Figure 5 , Figure 6 There are four positioning holes 1013, which are respectively located at the four corners of the top of the mold mechanism 1;

[0034] By opening four positioning holes 1013 at the four corners of the top of the mold mechanism 1, the accuracy and stability of the positioning of the workpiece or other components are further enhanced, the workpiece is positioned from multiple directions, the positioning error is reduced, and the quality of the stamped parts is improved.

[0035] See Figure 3 , Figure 5 The top surface of the mold mechanism 1 is fixedly connected to the four corners of the top surface of the mold mechanism 1, and the top of the guide rod assembly 1014 is fixedly connected to the cover plate mechanism 3.

[0036] The guide rod assemblies 1014 located at the four corners of the top of the mold mechanism 1 not only provide guidance for the moving mechanism 2, but also enhance the stability of the overall mold structure; the cover plate mechanism 3 at the top of the guide rod assembly 1014 plays a protective role, protecting the internal components from external interference, and at the same time providing installation positions for components such as the hydraulic assembly 301.

[0037] See Figure 1 , Figure 3 A hydraulic component 301 is fixedly connected to the center of the bottom end face of the cover plate mechanism 3. The bottom end of the hydraulic component 301 is connected to the top end of the moving mechanism 2. A warning light 3011 is fixedly connected to the top end face of the cover plate mechanism 3.

[0038] The hydraulic component 301 at the bottom of the cover plate mechanism 3 provides power to the moving mechanism 2, enabling it to move up and down on the guide rod assembly 1014 to achieve the stamping action; the warning light 3011 at the top of the cover plate mechanism 3 will sound an alarm when an abnormality occurs during the stamping process, reminding the operator to deal with it in time, avoid damage to the mold and workpiece, and ensure production safety.

[0039] During operation, firstly, using the mounting components 1011 and mounting slots 1012, the mold mechanism 1 is installed on the stamping equipment using bolts and other connecting parts. There are two mounting components 1011, which are fixed on the left and right sides of the mold mechanism 1 respectively. This symmetrical arrangement ensures the stability of the mold installation. The positioning holes 1013 at the four corners of the top of the mold mechanism 1 are used for precise positioning during mold installation to ensure that the relative position of the mold and the stamping equipment is accurate. At the same time, it is checked whether each component is installed firmly, such as whether the guide rod assembly 1014 is tightly fixed to the top of the mold mechanism 1, and whether the moving mechanism 2 can be smoothly connected to the guide rod assembly 1014.

[0040] Then, the automotive parts to be stamped are placed in the mold cavity assembly 101 at the top of the mold mechanism 1. At this time, the moving mechanism 2 is sleeved on the guide rod assembly 1014. The guide holes 201 at the four corners of the moving mechanism 2 cooperate with the guide rod assembly 1014 to play a precise guiding role, ensuring the stability and accuracy of the moving mechanism 2 during the up and down movement. The U-shaped guide frame assembly 2012 at the top of the moving mechanism 2 is inserted with the push rod assembly 2014, and the contact switch 2013 on the bottom surface of the horizontal component of the guide frame assembly 2012 is in a standby state. The baffle assembly 2015 on the outside of the push rod assembly 2014 is located directly below the contact switch 2013 to prepare for monitoring the stamping process.

[0041] When the stamping equipment is started, the hydraulic component 301 begins to work. The hydraulic component 301 is fixed at the center of the bottom end face of the cover plate mechanism 3, and its bottom end is connected to the top end of the moving mechanism 2, providing power to the moving mechanism 2 and pushing it downwards along the guide rod assembly 1014. The stamping component 2011 at the bottom of the moving mechanism 2 moves downwards accordingly, performing stamping operations on the automotive parts inside the mold cavity assembly 101. During the descent of the moving mechanism 2, if the workpiece is correctly positioned, the ejector rod assembly 2014 will not experience additional resistance and will descend along with the moving mechanism 2. When mechanism 2 descends to a certain position, if the push rod assembly 2014 touches the workpiece or other abnormal obstacles, the push rod assembly 2014 will move upward, thereby triggering the contact switch 2013. The contact switch 2013 transmits a signal to the built-in control system in the warning light 3011. The control system immediately controls the hydraulic assembly 301 to stop working to prevent the stamping assembly 2011 from making incorrect contact with the workpiece and avoid damage to the mold and workpiece. If the push rod assembly 2014 does not touch any abnormality, the stamping operation proceeds normally, and the stamping assembly 2011 applies pressure to the workpiece to form it.

[0042] After the stamping is completed, the hydraulic component 301 reverses its operation, pushing the moving mechanism 2 to move upward along the guide rod assembly 1014 to reset. During the upward movement of the moving mechanism 2, the top plate assembly 2016 at the top of the push rod assembly 2014 is connected to the guide frame assembly 2012 through the reset spring 2017. The reset spring 2017 provides an upward pulling force to help the guide frame assembly 2012 and the moving mechanism 2 rise and reset more stably. It also plays a certain reset role for the push rod assembly 2014, returning it to its initial position and preparing it for the next stamping operation.

[0043] If any abnormal situation occurs during the entire stamping process, such as when the contact switch 2013 is triggered, the control system will control the warning light 3011 to light up. The warning light 3011 is fixed on the top surface of the cover plate mechanism 3. When it lights up, it can promptly remind the operator to stop the equipment, check the mold and workpiece status, and take appropriate measures.

[0044] In summary, this device, equipped with a warning light 3011, can quickly trigger an alarm when an abnormality occurs.

[0045] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
