DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] As Figures 1 to 5As shown in the figure, a positioning pin structure with adjustable position according to an embodiment of the present utility model includes a mold 1; two modules 10 are installed on the top of the mold 1; a material collecting groove 11 is formed in the middle of the module 10; a lower die insert 12 is installed on the top of the mold 1; two mounting blocks 13 are installed in the middle of the lower die insert 12; a positioning pin body 14 is provided in the middle of the mounting block 13; the positioning pin body 14 includes a hanging platform 15, a fixed section 16, a positioning section 17, and a guiding section 18; a hanging platform 15 is provided at the bottom position of the positioning pin body 14; a fixed section 16 is provided in the middle position of the positioning pin body 14; a guiding section 18 is provided at the top position of the positioning pin body 14; a positioning section 17 is provided between the guiding section 18 and the fixed section 16; a fixing groove 19 is formed at the top of the mounting block 13; two material collecting plates 110 are fixedly connected to the bottom of the mold 1; the two material collecting plates 110 are arranged oppositely; the material collecting plates 110 are inclined; during work, the positioning pin body 14 is inserted from the bottom of the mounting block 13. First, the guiding section 18 and the positioning section 17 pass through the middle of the mounting block 13 and move to the top of the mounting block 13, the fixed section 16 enters the middle of the mounting block 13, and the hanging platform 15 is stuck at the bottom position of the mounting block 13. After the positioning pin body 14 is installed in the middle of the mounting block 13, the mounting block 13 is placed in the middle of the lower die insert 12, and then the mounting block 13 is fixed on the lower die insert 12 by screws. The screw through holes also serve as extraction holes. The sheet material is placed on the mold 1 by a manipulator. The positioning section 17 and the guiding section 18 on the positioning pin body 14 correspond to the positioning holes on the sheet material, so as to position and stamp the sheet material. When the sheet material is stamped, the generated waste falls into the middle of the material collecting plate 110 through the material collecting groove 11 and is discharged. The positioning pin body 14 can effectively position the sheet material accurately, reduce the position offset of the sheet material caused by pressure and vibration during the stamping process, and effectively reduce the problem of dimensional error caused by the position offset of the sheet material. The hanging platform 15 on the positioning pin body 14 can effectively reduce the phenomenon of the sheet material falling off when it is fixed. The guiding section 18 can effectively guide the sheet material to be positioned by the positioning section 17. And when the diameter of the positioning pin body 14 changes, the positioning pin body 14 can be directly replaced, effectively reducing the operation of reprocessing the lower die insert 12. The screws installed in the fixing groove 19 can quickly install and disassemble the mounting block 13 in the lower die insert 12. When positioning pins with different diameters are required for the positioning pin body 14, the processing requirements for the lower die insert 12 can be reduced, and the position adjustment of the positioning pin body 14 can be effectively facilitated without secondary processing of the mold 1, effectively improving the processing efficiency and quality.

[0028] As Figures 1 to 3As shown in the figure, two sets of sliding grooves 2 are provided at the top of the mold 1; every two of the sliding grooves 2 form a set; the two sliding grooves 2 are arranged oppositely; a first fixing hole 23 is provided at the bottom of the sliding groove 2; a positioning rod 21 is fixedly connected to the middle of the sliding groove 2; a fixing bolt 22 is installed in the middle of the positioning rod 21; the end of the fixing bolt 22 is threadedly connected to the middle of the first fixing hole 23; during work, the positioning rod 21 is placed inside the sliding groove 2, the fixing bolt 22 is inserted into the middle of the positioning rod 21, the end of the fixing bolt 22 corresponds to the position of the first fixing hole 23, and the fixing bolt 22 is tightened to fix the positioning rod 21 inside the sliding groove 2. The top of the positioning rod 21 is arc-shaped. When the sheet material is placed on the mold 1 for positioning, it is guided through the top of the positioning rod 21, and the two sides of the sheet material are positioned by the positioning rod 21. The positioning rod 21 can keep the sheet material in the correct position on the mold 1, effectively reduce the problem of offset generated during the stamping process, effectively reduce the error caused by the incorrect position of the sheet material, effectively increase the accurate stamping position of the sheet material, and the positioning rod 21 can play a role of fixing and supporting during the stamping process, effectively reducing the deformation of the sheet material caused by the punching force.

[0029] As Figure 1 and Figure 2 shown in the figure, two sets of second fixing holes 3 are provided at the end of the mold 1; the two sets of second fixing holes 3 are arranged oppositely; a fixing screw 31 is threadedly connected to the middle of the second fixing hole 3; a first fixing ring 32 is fixedly connected to the end of the fixing screw 31; during work, one end of the fixing screw 31 is placed in the middle of the second fixing hole 3, and the first fixing ring 32 is rotated to make the fixing screw 31 rotate inside the second fixing hole 3. The first fixing ring 32 is fixed to the end of the mold 1 through the fixing screw 31, and then one end of the steel rope is connected to the first fixing ring 32. The two ends of the mold 1 are tightened by the steel rope to keep the fixed position. Connecting the mold 1 through the first fixing ring 32 and the steel rope can effectively reduce the problem of offset caused by uneven force or vibration during the stamping process of the sheet material, effectively keep the mold 1 in the predetermined position all the time, effectively reduce the error of the sheet material accuracy caused by the change of the position of the mold 1 during the stamping process, and the stable fixing of the mold 1 can maintain the continuity and stability during the stamping process.

[0030] As Figure 5 and Figure 6As shown, two slide rails 4 are fixedly connected to the side wall of the aggregate plate 110; the two slide rails 4 are arranged oppositely; a slide plate 41 is slidably connected to the middle of the two slide rails 4; two springs 42 are fixedly connected to the side wall of the slide plate 41; the ends of the two springs 42 are fixedly connected to the end of the aggregate plate 110; a scraping strip 43 is fixedly connected to the bottom of the slide plate 41; the bottom of the scraping strip 43 is attached to the surface of the aggregate plate 110; two pull ropes 44 are fixedly connected to the side wall of the slide plate 41; the end of the pull rope 44 is fixedly connected to a second fixing ring 46; two fixing hooks 45 are fixedly connected to the middle of the aggregate plate 110; during operation, when the sheet material is being stamped, the waste generated falls into the aggregate plate 110 through the middle of the lower die insert 12. Due to the inclined setting of the aggregate plate 110, the waste naturally slides out. Some waste stays on the surface of the aggregate plate 110. Pull the two pull ropes 44 to make the slide plate 41 slide inside the slide rail 4. When the slide plate 41 is pulled, the two springs 42 are simultaneously elastically stretched. The residual waste is scraped off and discharged by the bottom of the scraping strip 43 being attached to the aggregate plate 110. When the waste is scraped off, relax the pull ropes 44. The slide plate 41 slides and resets inside the slide rail 4 through the elastic contraction of the springs 42. Put the second fixing ring 46 on the middle of the fixing hook 45 to fix the end of the pull rope 44. The slide plate 41 can effectively reduce the waste remaining on the surface of the aggregate plate 110, effectively reduce the accumulation of waste on the surface of the aggregate plate 110 due to not being cleaned in time, effectively reduce the blockage problem caused by the accumulation of waste on the surface of the aggregate plate 110, effectively reduce the unsmooth discharge of subsequent waste, and effectively reduce the wear caused by the accumulation of waste on the surface of the aggregate plate 110, effectively improving the cleaning efficiency of the waste.

[0031] As Figure 5 and Figure 6 shown, two sponge blocks 5 are fixedly connected to the side wall of the slide plate 41; the two sponge blocks 5 are arranged inside the corresponding slide rails 4; during operation, when the slide plate 41 slides inside the slide rail 4, the sponge blocks 5 slide inside the slide rail 4 along with the slide plate 41. The inside of the slide rail 4 is cleaned by the sponge blocks 5. By the sponge blocks 5 sliding inside the slide rail 4 along with the slide plate 41, the clean state of the inside of the slide rail 4 can be effectively maintained, effectively reducing the accumulation of waste inside the slide rail 4 during the process of the aggregate plate 110 collecting waste. The sponge blocks 5 can reduce the resistance on the slide plate 41 during the sliding process due to the accumulation of waste inside the slide rail 4, and can protect the smoothness of the inside of the slide rail 4, effectively keeping the slide plate 41 moving smoothly.

[0032] As Figure 5As shown, two baffles 6 are fixedly connected to the top of the aggregate plate 110; the two baffles 6 are arranged oppositely; the two baffles 6 are arc-shaped; during operation, when the waste falls on the aggregate plate 110, the two baffles 6 block the waste from splashing around when it falls, and the baffles 6 can effectively guide the waste, effectively intercept the splashing waste so that it accurately falls into the aggregate plate 110, and can effectively reduce the pollution caused by the waste scattered around the working environment, thereby maintaining the cleanliness and air quality of the working environment.

[0033] During operation, insert the positioning pin body 14 from the bottom of the mounting block 13. First, the guiding section 18 and the positioning section 17 pass through the middle of the mounting block 13 and move to the top of the mounting block 13. The fixing section 16 enters the middle of the mounting block 13, and the hanging platform 15 is stuck at the bottom position of the mounting block 13. After installing the positioning pin body 14 in the middle of the mounting block 13, place the mounting block 13 in the middle of the lower die insert 12, and then fix the mounting block 13 on the lower die insert 12 with screws. The screw through holes are also used as extraction holes. Place the sheet metal on the die 1 through a manipulator. Align the positioning section 17 and the guiding section 18 on the positioning pin body 14 with the positioning holes on the sheet metal, so as to position and stamp the sheet metal. When the sheet metal is being stamped, the generated waste falls through the aggregate chute 11 to the middle of the aggregate plate 110 and is discharged. Place the positioning rod 21 in the chute 2, insert the fixing bolt 22 into the middle of the positioning rod 21, and align the end of the fixing bolt 22 with the position of the first fixing hole 23. Tighten the fixing bolt 22 to fix the positioning rod 21 inside the chute 2. The top of the positioning rod 21 is arc-shaped. When the sheet metal is placed on the die 1 for positioning, it is guided through the top of the positioning rod 21, and the two sides of the sheet metal are positioned by the positioning rod 21. Place one end of the fixing screw 31 in the second fixing hole 3, turn the first fixing ring 32 to make the fixing screw 31 rotate inside the second fixing hole 3, and fix the first fixing ring 32 at the end of the die 1 through the fixing screw 31. Then connect one end of the steel rope to the first fixing ring 32, and tighten the two ends of the die 1 with the steel rope to maintain a fixed position. When the sheet metal is being stamped, the generated waste falls into the aggregate plate 110 through the middle of the lower die insert 12. Due to the inclined setting of the aggregate plate 110, the waste naturally slides out. Some waste remains on the surface of the aggregate plate 110. Pull the two pull ropes 44 to make the sliding plate 41 slide inside the slide rail 4. When the sliding plate 41 is pulled, the two springs 42 are elastically stretched at the same time. Scrape the remaining waste and discharge it by making the bottom of the scraping strip 43 fit with the aggregate plate 110. After scraping the waste, relax the pull ropes 44, and the sliding plate 41 slides back inside the slide rail 4 through the elastic contraction of the springs 42. Put the second fixing ring 46 on the middle of the fixing hook 45 to fix the end of the pull rope 44. When the sliding plate 41 slides inside the slide rail 4, the sponge block 5 slides inside the slide rail 4 at the same time as the sliding plate 41, and the inside of the slide rail 4 is cleaned by the sponge block 5. When the waste falls on the aggregate plate 110, the two baffles 6 block the waste from splashing around when it falls.
