Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and specifically relates to a stamping die and a protective structure. Background Technology

[0002] Stamping dies are core equipment in the forming and processing of sheet metal. By applying instantaneous impact force through a press (such as a punch press or hydraulic press), the sheet metal is sheared, bent, stretched, or formed, thereby efficiently mass-producing parts with consistent shapes and dimensions. During stamping operations, the closed area of ​​the die is a relatively dangerous area. If an operator's limb accidentally enters this area, it can cause severe crushing, shearing injuries, or even fatal accidents. Secondly, during stamping, the sheet metal is sheared or punched, producing sharp debris that can fly and cause physical injuries such as cuts or punctures. Furthermore, due to high-speed impact and friction during stamping, the debris may be hot, causing burns upon contact with skin, posing a safety hazard to the operator. Therefore, a new structure is proposed to address these problems. Utility Model Content

[0027] Please see Figures 1 to 6 A stamping die and protective structure, comprising: a protective component 300 and a slide rail assembly 200, wherein the protective component 300 includes a pair of mirror-symmetrically arranged protective plates 310, the bottom of the protective plates 310 having a slide groove 312, and the slide rail assembly 200 is installed below the protective component 300.

[0028] The slide rail assembly 200 is installed on the upper surface of the worktable 100. The slide rail assembly 200 includes a slide rail body 210 that slides and matches the slide groove 312. Several sets of steel balls 211 are embedded in the top of the slide rail body 210 from left to right.

[0029] The upper surface of the worktable 100 has a mold closing area on the rear side. A lower mold base is installed below the mold closing area, and an upper mold base is installed above the lower mold base. The top center of the upper mold base is connected to the lower output end of the hydraulic press above it.

[0030] The slide rail assembly 200 is installed directly in front of the mold closing area. The slide rail body 210 has a T-shaped cross-section. The worktable 100 at the left and right positions of the slide rail body 210 has an installation groove 101 on its upper surface.

The bottom of the protective plates 310 does not contact the upper surface of the workbench 100. A pair of magnetic strips 311 are glued to the opposite side of each set of protective plates 310, and the magnetic strips 311 glued to the two sets of protective plates 310 have opposite poles facing each other.

[0034] A rolling groove 313 is horizontally opened on the upper inner surface of the slide groove 312. The depth of the rolling groove 313 matches the radius of the steel ball 211. Several sets of steel balls 211 are of the same specification and are all movably embedded in the top of the slide rail body 210.

[0035] A support platform 110 is installed sequentially from front to back on the right side of the workbench 100, and an electric push rod 120 is installed on the upper surface of each support platform 110.

[0036] The left output ends of the two sets of electric push rods 120 are fixed to the side of their respective protective plates 310, and the specifications of the left and right sides of the worktable 100 are exactly the same.

[0037] Example 1: Please refer to Figures 1 to 6 In actual use, a mold closing area is provided on the rear side of the upper surface of the workbench 100. A lower mold base is installed below the mold closing area, and an upper mold base is installed above the lower mold base. The top center of the upper mold base is connected to the lower output end of the hydraulic press above it (the stamping process is existing technology, and its structure and working principle will not be described in detail here). A slide rail assembly 200 is installed horizontally in front of the mold closing area. The slide rail assembly 200 includes a slide rail body 210 and a base plate. The base plate is fixed to the upper surface of the workbench 100 by bolts. The slide rail body 210 is welded to the upper surface of the base plate. The cross-section of the slide rail body 210 is a T-shaped structure, and several [unclear] are embedded in the top of the slide rail body 210 from left to right. A set of steel balls 211 of the same specification are mounted on the slide rail assembly 200. A protective assembly 300 is installed above the slide rail assembly 200. The protective assembly 300 includes a pair of protective plates 310 for protection. The protective plates 310 have an L-shaped structure. The two sets of protective plates 310 are of the same specification and are arranged in a mirror symmetrical manner. A slide groove 312 matching the specification of the slide rail body 210 is opened below the protective plate 310. A rolling groove 313 for the steel balls 211 to roll is opened on the upper inner surface of the slide groove 312. Both sets of protective plates 310 are made of acrylic material. A pair of magnetic strips 311 are glued to the opposite side of the two sets of protective plates 310. The magnetic strips 311 glued to the two sets of protective plates 310 are of the same specification and have opposite poles facing each other.

[0038] A support platform 110 is installed on the front and rear positions of the right side of the workbench 100. An electric actuator 120 is mounted on the upper surface of each support platform 110. The output end of the electric actuator 120 on its left side is fixed to the side of the corresponding protective plate 310. The structure and specifications of the left and right sides of the workbench 100 are identical. The four sets of electric actuators 120 are a synchronous mechanism. In actual use, all four sets of electric actuators 120 are activated simultaneously (the electric actuator 120 is existing technology, and its internal structure and working principle will not be described here), pushing the two sets of protective plates 310 to move relative to each other. During the movement... Several sets of steel balls 211 roll along the inner side of the rolling groove 313, which can effectively reduce the friction between the slide rail body 210 and the slide groove 312, making the movement of the protective plate 310 more stable and effortless. When the opposite sides of the two sets of protective plates 310 come into contact, the two sets of magnetic strips 311 on the left and the two sets of magnetic strips 311 on the right are attracted and fixed, thereby attracting and fixing the two sets of protective plates 310. At this time, the two sets of protective plates 310 respectively shield the front side and the left and right sides of the mold closing area, which can effectively prevent the metal chips cut off from splashing, and significantly improve the protection effect for the operator.

[0039] Example 2: Please refer to Figure 1 , Figure 3 and Figure 4 On the upper surface of the worktable 100 below the left and right sides of the slide rail assembly 200, there is an installation groove 101. A magnetic block 102 is installed on the lower inner surface of the installation groove 101. A limiting plate 220 is installed inside the installation groove 101. At the bottom of the limiting plate 220, there is a magnetic block 221 of the same specifications as the magnetic block 102 but with opposite poles. The two limiting plates 220 are of the same specifications, and a pressure sensor 230 is installed on the opposite side of the two limiting plates 220. When the two limiting plates 220 are inserted into the two installation grooves 101, the magnetic block 102 and the magnetic block 221 are attracted and fixed. When the two protective plates 310 move in opposite directions, the space in front of the mold closing area is opened. When the two sets of protective plates 310 simultaneously press the pressure sensor 230 on the side of the opposite limiting plate 220 (the pressure sensor 230 is existing technology, and its internal structure and working principle will not be described here), after the pressure sensor 230 senses the pressure signal, it stops the hydraulic press from continuing to work through the external control system. This makes it easier for the operator to check the mold closing area and protect the operator's safety. Secondly, the two sets of limiting plates 220 can be pulled upward from the two sets of mounting slots 101 respectively, so that the magnetic block 221 at the bottom of the limiting plate 220 is separated from the magnetic block 102 at the bottom of the mounting slot 101. Then the two sets of limiting plates 220 can be removed, which is convenient for maintenance and replacement of the limiting plates 220.
