Detailed Description
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present invention only, and are not intended to limit the present invention.
Examples: as shown in fig. 1-3, the high-precision scrap-jumping prevention stamping die comprises an upper die holder 2 and a lower die holder 1 which can relatively move up and down, wherein two guide posts 4 are symmetrically arranged on two sides of the lower die holder 1, the tops of the guide posts 4 are fixedly connected with guide post holes 3 on two sides of the upper die holder 2 in a penetrating manner, a lower die base plate 5 for buffering and fixing is fixedly arranged on the top end of the lower die holder 1, a lower die plate 6 for processing is arranged on the top end of the lower die base plate 5, a stripper column 14 is respectively arranged on two sides of the middle part of the lower die plate 6, positioning holes 18 are symmetrically formed on two sides of the lower die plate 6 and the lower die base plate 5, positioning pins 7 are fixedly arranged on two sides of the bottom of the upper die holder 2, the positioning pins 7 are symmetrically arranged with the positioning holes 18, the bottom of the upper die holder 2 is fixedly connected with a stripper baffle 8 through two symmetrical springs 9, two sides of the stripper baffle 8 are alternately connected with the positioning pins 7 through holes, two sides of the stripper baffle 8 are symmetrically arranged on two sides of the stripper baffle 8, a cutter 13 is correspondingly arranged on two sides of the stripper column 13, and one end of the cutter 11 penetrates through the middle part of the stripper column 11 is arranged on the cutter 11.
The top of the spring 9 is provided with a spring positioning block 10, the spring positioning block 10 is movably connected with the upper die holder 2, the bottom of the spring 9 is in threaded connection with the stripping baffle 8, and the spring is fixed with the upper die holder through the spring positioning block.
The stripping column 14 consists of a bearing sleeve 15, an elbow 16 and a connecting rod 17, wherein the outer wall of the bottom of the bearing sleeve 15 is in threaded connection with the lower die plate 6 through a set threaded coil, two ends of the connecting rod 17 are respectively welded and fixed with the inner wall of the bearing sleeve 15 and the bottom of the elbow 16, one convex side of the elbow 16 is close to the center of the lower die plate 6, the convex part of the elbow 16 is utilized to fix a plate material, and the movement of the plate material before stamping is reduced.
Wherein, punching press hole 12 is the back taper platform shape, and when punching press cutter 11 down punching press, punching press cutter 11 can extrude the periphery of waste material, makes its deformation, and its shape then can not change along with punching press cutter 11, reduces the burr that appears in the course of working, improves the quality of processing work piece.
When the upper die holder 2 moves downwards, firstly, the locating pin 7 enters the inside of the locating hole 18, at this time, under the cooperation of the locating pin 7 and the locating hole 18, the positions of the lower die base plate 5 and the lower die plate 6 relative to the upper die holder 2 and the punching cutter 11 cannot be changed, the punching cutter 11 is beneficial to aligning with the punching hole 12, the lower die plate 6 is limited in the horizontal and vertical directions through the locating pin 7, and the machining precision is improved.
When the stripping baffle 8 and the lower die plate 6 are completely bonded, the stripping column 14 is just inserted into the groove 13, the spring 9 is deformed at the moment, the punching cutter 11 enters the punching hole 12 to punch the mixed material, and the stripping baffle 8 is pressed against the lower die plate 6 and the plate material by utilizing the deformation of the spring 9 in the compression process, so that the movement of the plate material in the punching process is reduced.
When the stripper baffle 8 and the lower die plate 6 are separated, the spring 9 firstly pushes the stripper baffle 8 downwards under the action of restoring force, so that the stripper baffle 8 props against waste materials when the punching tool 11 returns, and the waste materials are prevented from moving away from the lower die plate 6 along with the movement of the cutting tool 11, thereby playing the role of preventing the waste materials from jumping.
Specifically, the plate is placed between two stripping columns 14, an elbow 16 for preventing the plate from being separated from the lower die plate 6 is welded at the top of each stripping column 14, when the upper die holder 2 is extruded downwards, the positioning pin 7 firstly enters the inside of the positioning hole 18, the position of the lower die plate 6 relative to the punching tool 11 cannot be changed through the cooperation of the positioning pin 7 and the positioning hole 18, and the follow-up punching tool 11 can smoothly enter the punching hole 12 through limiting in the horizontal and vertical directions, so that the punching precision can be effectively improved; when the stripper baffle 8 contacts with the lower die plate 6, the stripper column 14 is clamped with the groove 13, the stripper baffle 8 does not move downwards continuously, at this time, the spring 9 can generate certain compression, the punching cutter 11 moves downwards continuously under the action of external force and enters into the punching hole 12, the punching hole 12 is in a reverse taper table shape, when the punching cutter 11 punches downwards, the punching cutter 11 can squeeze the periphery of the waste to deform the periphery, the shape of the periphery does not change along with the punching cutter 11, when the upper die holder 2 returns upwards, the stripper baffle 8 and the lower die plate 6 are separated, the spring 9 pushes the stripper baffle 8 downwards under the action of restoring force, so that the stripper baffle 8 props against the waste when the punching cutter 11 returns, the waste is effectively prevented from separating from the stripper column 14 and the lower die plate 6, and a punched workpiece can be separated out of the die through the punching hole 12.
This kind of high accuracy prevents jumping waste material stamping die utilizes locating pin 7 and locating hole 18 cooperation, makes the relative position between lower bolster 6 and the punching press cutter 11 be difficult for taking place to change and then improves machining precision, when placing the sheet material, places the sheet material between two and takes off the material post 14, and in-process that upper die base 2 replied, spring 9 is under the effect of restoring force support and takes off material baffle 8, takes off material baffle 8 and can support the waste material, prevents that the waste material from breaking away from lower bolster 6 along with punching press cutter 11 more to play the effect of preventing jumping the waste material.
Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present invention, and the present invention is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present invention has been described in detail with reference to the foregoing embodiments.
