Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping die technology, specifically to a stamping die processing equipment for production. Background Technology
[0002] In the manufacturing process of hardware products, stamping machines are often used for processing. For example, one side of the workpiece to be processed can be pressed into a fixed structure or shape. The specific steps are as follows: First, the workpiece to be processed is placed in the groove of the base, with the side to be stamped facing the stamping system; then, the stamping system drives the die to apply external force to the workpiece to be processed, causing plastic deformation of the workpiece; finally, the processed part is taken out from the groove, thereby obtaining the workpiece of the desired shape.
[0003] A search of the China Patent Network revealed a stamping die processing equipment for production, which allows for the placement and removal of parts outside the stamping die. The operation is not limited by the space between the upper and lower dies, making it convenient and reducing the danger of handling parts.
[0004] However, because the stamped sheet metal has the same size as the internal size of the mold cavity, the gap between the two is very small, causing the stamped sheet metal to fit tightly into the mold cavity. It is difficult to remove by hand alone, and tools are even needed to pry it out. This results in a certain amount of time being spent removing the stamped sheet metal, and there is also a potential risk of scratching the stamped sheet metal. Therefore, a stamping die processing equipment for production is proposed. Utility Model Content
[0005] Based on this, the purpose of this utility model is to provide a stamping die processing equipment for production, so as to solve the technical problem mentioned in the background that it is difficult to remove the stamped sheet, resulting in low stamping efficiency of the sheet.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a stamping die processing equipment for production, including a base plate, a die assembly mounted on the top of the base plate, a positioning plate fixed to the top of the base plate by four sets of positioning shafts above the die assembly, a stamping head of a stamping sheet below the positioning plate, and a hydraulic cylinder for driving the stamping head to rise and fall on the top of the positioning plate.
[0007] The mold assembly includes an outer frame fixed to the top of a base plate. A mold core is movably disposed within the outer frame. A panel is fixed to the front surface of the mold core. Two sets of rectangular grooves are formed on the rear surface of the mold core. A U-frame is slidably disposed within each set of rectangular grooves. A guide rod fixed to the inner rear wall of the outer frame is fitted inside the U-frame. A fixed piece fixed to the inner wall of the U-frame is movably fitted on the outer wall of the guide rod. A movable piece sliding inside the U-frame is fixed near the front end of the outer wall of the guide rod. Two sets of trapezoidal blocks are fixed to the upper surface of the U-frame. One end of each trapezoidal block pushes up a ball joint of a plate. A positioning hole is formed at the contact position between the upper surface of the mold core and the ball joint, and the positioning hole is in communication with the rectangular groove.
[0008] As a preferred technical solution, a spring is sleeved on the outer wall of the guide rod, and the end of the spring is fixed to the outer wall of the fixed plate.
[0009] As a preferred technical solution, a top plate is fixed to the top of the ball head rod, and a receiving groove that matches the top plate is reserved on the top of the mold core.
[0010] As a preferred technical solution, the length of the U-frame is smaller than the length of the rectangular groove.
[0011] As a preferred technical solution, the panel, the mold core and the outer frame constitute a mold cavity, the left and right outer walls of the outer frame are provided with reinforcing arms fixed to the upper surface of the base plate, and the front surface of the panel is welded with a pull handle.
[0012] As a preferred technical solution, the top of the stamping plate head is provided with a top cover fixed to the telescopic end of the hydraulic cylinder, and the bottom of the top cover is reserved with a positioning groove for installing the stamping plate head. The stamping plate head is detachably connected to the positioning groove by bolts.
[0013] As a preferred technical solution, the size of the stamping plate head corresponds to the mold cavity, and the top of the mold core is reserved with a stamping groove that matches the stamping plate head.
[0014] In summary, the present invention has the following main advantages:
[0015] This invention allows the die core to move forward, positioning the stamped sheet metal below the stamping head. This allows for manual removal of the sheet metal without constraint and eliminates the potential risk of crushing injuries, thus providing better protection for workers. Simultaneously, pulling the die core outward causes the ball joint to push the stamped sheet metal upward, allowing for direct removal by the worker. This shortens the time required for sheet metal removal and indirectly improves the efficiency of the equipment in stamping sheet metal. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0025] The embodiments of this utility model will be described below based on its overall structure.
[0026] A stamping die processing equipment for production, such as Figures 1 to 5 As shown, the assembly includes a base plate 100, a mold assembly 200 is mounted on the top of the base plate 100, a positioning plate 110 is fixed to the top of the base plate 100 by four sets of positioning shafts above the mold assembly 200, a stamping head 140 for stamping sheet is provided below the positioning plate 110, and a hydraulic cylinder 120 for driving the stamping head 140 to rise and fall is mounted on the top of the positioning plate 110.
[0027] The mold assembly 200 includes an outer frame 210 fixed to the top of the base plate 100. A mold core 220 is movably disposed inside the outer frame 210. A panel 230 is fixed to the front surface of the mold core 220. Two sets of rectangular grooves 240 are opened on the rear surface of the mold core 220. A U-frame 270 is slidably disposed in each set of rectangular grooves 240. A guide rod 280 fixed to the rear inner wall of the outer frame 210 is sleeved inside the U-frame 270. A fixed piece 282 fixed to the inner wall of the U-frame 270 is movably sleeved on the outer wall of the guide rod 280. A movable piece 281 that slides inside the U-frame 270 is fixed near the front end of the outer wall of the guide rod 280. Two sets of trapezoidal blocks 290 are fixed to the upper surface of the U-frame 270. A ball head rod 260 of the plate is pushed up on one side of the end of the trapezoidal block 290. A positioning hole 250 is opened at the contact position between the upper surface of the mold core 220 and the ball head rod 260. The positioning hole 250 is in a connected state with the rectangular groove 240.
[0028] A spring 283 is sleeved on the outer wall of the guide rod 280, and the end of the spring 283 is fixed to the outer wall of the fixed plate 282.
[0029] The sliders of the U-frame 270 are fixed to the outer walls of the left and right sides and slide on the inner wall of the rectangular groove 240. The inner wall of the rectangular groove 240 is provided with a groove for the slider to slide.
[0030] When the extension end of the hydraulic cylinder 120 is lowered, it can push the stamping plate head 140 to lower and complete the stamping action on the plate on the top of the mold core 220. Afterwards, the extension end of the hydraulic cylinder 120 drives the stamping plate head 140 to rise and return to its original position. At this time, the manual hand applies an external force to the mold core 220 towards the side closer to the body. The mold core 220 will move forward along the outer frame 210. Since the guide rod 280 and the outer frame 210 are in a fixed state, and the U-frame 270 can only slide slightly within the rectangular groove 240 under the constraint of the slider and the slide groove, the U-frame 270 will move forward along the outer wall of the guide rod 280 with the mold core 220 until the mold core 220 moves to the outside of the stamping plate head 140, which makes it easy for the manual to remove the stamped plate without being constrained by the stamping plate head 140.
[0031] When the U-frame 270 moves forward, due to the fixed piece 282, the travel distance of the U-frame 270 is less than the length of the guide rod 280. Therefore, the moving piece 281 on the outer wall of the guide rod 280 will contact the fixed piece 282 and drive the U-frame 270 to move in the rectangular groove 240 towards the outer frame 210. The inclined surface of the trapezoidal block 290 will squeeze the ball head rod 260 to rise upward. The plate stamped on the top of the mold core 220 is lifted upward by the top plate 261, completing the final demolding purpose. This allows the plate to be directly removed when the mold core 220 is manually pulled out.
[0032] When the mold core 220 resets and enters the outer frame 210, the end face of the spring 283 will contact the outer frame 210, pushing the U-frame 270 back to its original position. At the same time, the ball joint 260 will lower and reset due to its own weight, making it easier to lift the stamped plate next time.
[0033] Please refer to this carefully. Figure 4 The top of the ball head 260 is fixed with a top plate 261, and the top of the mold core 220 is reserved with a receiving groove that matches the top plate 261.
[0034] By increasing the contact area between the top plate 261 and the bottom of the ejected plate, the plate can be ejected more effectively to complete the demolding. At the same time, the round groove provides space for the top plate 261 to stand, so that it is flush with the top of the mold core 220, ensuring that the stamped plate achieves the standard shape.
[0035] Please refer to this carefully. Figure 4 The length of the U-frame 270 is less than the length of the rectangular slot 240.
[0036] This allows the U-frame 270 to move within the rectangular groove 240, thereby lifting the ball head rod 260 to complete the demolding of the plate.
[0037] Please refer to this carefully. Figure 1 and Figure 3 The panel 230, the mold core 220 and the outer frame 210 constitute the mold cavity. The left and right outer walls of the outer frame 210 are provided with reinforcing arms fixed to the upper surface of the base plate 100. A pull handle is welded to the front surface of the panel 230.
[0038] The dimensions of the stamping head 140 correspond to the mold cavity, and the top of the mold core 220 is reserved with a stamping groove that matches the stamping head 140.
[0039] The stamping head 140 and the mold cavity work together to complete the stamping of the sheet metal. The reinforcing arm enhances the strength of the mold cavity and prevents outward deformation due to the increase in the number of stampings. At the same time, the manual hand holds the handle and applies a forward pulling force, so that the mold core 220 moves forward synchronously, making it easy for the manual to remove the stamped sheet metal.
[0040] Please refer to this carefully. Figure 2 The top of the stamping plate head 140 is provided with a top cover 130 fixed to the telescopic end of the hydraulic cylinder 120. The bottom of the top cover 130 is reserved with a positioning groove for installing the stamping plate head 140. The stamping plate head 140 is detachably connected to the positioning groove by bolts.
[0041] Bolts allow for flexible disassembly of the stamping head 140, enabling replacement of damaged stamping heads 140 and thus ensuring the precision of the stamped parts.
[0042] In use, the extension end of the hydraulic cylinder 120 lowers, which can push the stamping plate head 140 to lower and complete the stamping action on the plate on the top of the mold core 220. Afterwards, the extension end of the hydraulic cylinder 120 drives the stamping plate head 140 to rise and return to its original position. At this time, the manual hand applies an external force to the mold core 220 towards the side closer to the body. The mold core 220 will move forward along the outer frame 210. Since the guide rod 280 and the outer frame 210 are in a fixed state, and the U-frame 270 can only slide slightly within the rectangular groove 240 under the constraint of the slider and the slide groove, the U-frame 270 will move forward along the outer wall of the guide rod 280 with the mold core 220 until the mold core 220 moves to the outside of the stamping plate head 140, which makes it easy for the manual to remove the stamped plate without being constrained by the stamping plate head 140.
[0043] When the U-frame 270 moves forward, due to the fixed piece 282, the travel distance of the U-frame 270 is less than the length of the guide rod 280. Therefore, the moving piece 281 on the outer wall of the guide rod 280 will contact the fixed piece 282 and drive the U-frame 270 to move in the rectangular groove 240 towards the outer frame 210. The inclined surface of the trapezoidal block 290 will squeeze the ball head rod 260 to rise upward. The plate stamped on the top of the mold core 220 is lifted upward by the top plate 261, completing the final demolding purpose. This allows the plate to be directly removed when the mold core 220 is manually pulled out.
