Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and more specifically, it relates to a progressive die for producing bushings for automobiles. Background Technology

[0002] In modern automotive manufacturing, various precision bushing parts are widely used as key transmission and connection components in core parts such as engines, suspension systems, and steering systems. These bushings have extremely high requirements for dimensional accuracy and surface quality. To meet the mass production needs of the automotive industry, progressive dies have become the main process equipment for the production of bushing parts, enabling high-efficiency and high-precision continuous stamping forming.

[0003] However, during the long-term use of progressive dies, the precision positioning elements inside the die inevitably experience wear due to repeated impact loads and friction. This wear directly affects the positioning accuracy and forming quality of the workpiece. When the wear reaches a certain level, it may even lead to an increase in the scrap rate, seriously affecting production efficiency and product qualification rate.

[0004] In practical mold maintenance and upkeep, rapid response and efficient repair are key requirements for ensuring continuous production line operation. When precision positioning components wear out and need replacement, traditional disassembly and assembly methods often require numerous disassembly steps and specialized tools. This is not only complex and time-consuming but also requires skilled maintenance personnel, making it particularly inconvenient under urgent production conditions. Current technology lacks designs for positioning components that facilitate rapid installation and disassembly, leading to excessively long mold repair times. This not only increases production costs and downtime losses but also risks damaging other mold components due to improper installation or disassembly errors, severely impacting mold lifespan and production line efficiency.

An upper die is fixedly mounted on the bottom surface of the top plate, and a lower die is fixedly mounted on the top surface of the bottom plate. A fixing mechanism is provided on the top plate, comprising a fixing sleeve and an insert rod. The fixing sleeve abuts against the top surface of the top plate, and the insert rod is inserted into the fixing sleeve. A guide sleeve is fixedly mounted at the bottom end of the insert rod, and the guide sleeve is inserted into the top plate. A guide rod is fixedly mounted on the bottom plate, and the guide rod is slidably connected to the inner side of the guide sleeve. A movable groove is provided on the inner side of the fixing sleeve, and multiple sets of locking blocks are slidably connected to the movable groove. A locking groove is provided on the outer wall of the insert rod, and the multiple sets of locking blocks are engaged in the locking groove.

[0007] The present invention is further provided that the top end of the insertion rod and the inner side of the multiple sets of the locking blocks are provided with inclined surfaces. The inclined surface design facilitates the smooth cooperation between the insertion rod and the locking blocks, reduces friction and improves assembly efficiency.

[0008] The present invention is further configured such that push springs are connected between the outer sides of the multiple sets of card blocks and the movable grooves, and multiple sets of push springs are provided. The push springs provide elastic force so that the card blocks can automatically reset and remain fastened, thereby improving the stability and reliability of the device.

[0009] The present invention is further provided with an unlocking sleeve slidingly provided on the outer wall of the card slot. The outer wall of the unlocking sleeve is set as an inclined surface. The inclined surface structure facilitates smooth force application during operation, thereby achieving quick unlocking and resetting.

[0010] The present invention is further configured such that a sliding plate is fixedly provided on the inner side of the unlocking sleeve, and multiple sets of sliding plates are provided. A sliding groove is provided on the outer wall of the insertion rod, and multiple sets of sliding grooves are provided and are slidably connected to multiple sets of sliding plates respectively. The cooperation between the sliding plate and the sliding groove improves the smoothness and reliability of the unlocking action.

[0011] The present invention is further configured such that a sliding rod is fixedly provided on the inner side of multiple sets of the sliding plate, the sliding rod is slidably connected to the plug rod and a pull block is fixedly provided at the top end, the pull block is designed to facilitate manual pulling to unlock, and improves the ease of operation.

[0012] The present invention is further provided that the top end of the fixing sleeve is provided with a clearance hole, which avoids interference and ensures the smoothness of the device during installation and disassembly.

[0013] The present invention is further configured such that a positioning hole is provided on the top plate, and the top end of the guide sleeve is inserted into the positioning hole.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a progressive die for producing automotive bushings, which has the following advantages: 1. This device effectively solves the problem of wear affecting production quality of precision positioning elements in existing progressive dies by using a fixed fit between the top and bottom plates and an innovative design of the fixing device. When the guide sleeve wears out after long-term use, the insertion structure of the fixed sleeve and the insert rod, combined with the automatic locking function of the locking block in the movable groove, ensures that the replaced guide sleeve and guide rod maintain a precise sliding fit, avoiding the decrease in positioning accuracy and forming quality problems caused by wear. This effectively guarantees the high precision requirements and product qualification rate of automotive bushing production, and significantly improves the service life and production stability of progressive dies.

[0015] 2. The unique quick installation mechanism of this device overcomes the shortcomings of traditional disassembly and assembly methods, which are complicated and time-consuming, through the clever cooperation between the inclined surface of the insertion rod and the locking block and the automatic reset function of the push spring. When the guide sleeve needs to be replaced, maintenance personnel do not need to use a lot of special tools or perform complicated disassembly procedures. They can complete the installation with just a simple plug-in operation, which greatly reduces the mold maintenance time and technical requirements, avoids the risk of mold damage caused by improper installation, and provides a reliable guarantee for the rapid response and efficient maintenance of the production line.

[0016] 3. The innovative quick disassembly device of this apparatus uses the linkage operation of the pull block driving the slide rod and the slide plate, combined with the sliding of the unlocking sleeve along the slot to push multiple blocks to disengage simultaneously, realizing one-click quick disassembly of the guide sleeve. This effectively solves the problem of the lack of a design that facilitates quick disassembly and assembly in the existing technology. When production tasks urgently require the rapid replacement of worn parts, it can significantly shorten downtime and maintenance cycle, significantly reduce production costs and downtime losses, and ensure the efficient operation and economic benefits of the continuous die in the mass production of automotive bushings.
