Description

Technical Field

[0001] This utility model belongs to the field of punching die technology, and in particular relates to a forming die position adjustment mechanism. Background Technology

[0002] When sheet metal is punched into products using a die, the sheet is limited by locating blocks on both sides. The friction between the sheet and the locating blocks is sliding friction. Over time, this can cause wear on the locating surfaces of the blocks, and the sliding friction can also generate powder from the sheet, affecting the surface quality of the punched product. Furthermore, current locating blocks use a method of adjustment using elongated holes and bolts, which results in low adjustment precision and inconvenience. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a molding die position adjustment mechanism that is easy to adjust and uses rolling friction between the sheet and the limiting wheel to avoid wear.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a molding die position adjustment mechanism, comprising a frame, a telescopic cylinder, a die seat, an upper pressure die, a linear slide rail, a lower die, a lead screw, a screw sleeve, a guide wheel, and a guide sleeve. The cylinder body of the telescopic cylinder is fixedly installed on the top of the frame. Four linear slide rails are distributed and fixedly installed on the inner walls of the left and right sides of the frame in pairs. Slider blocks are fixedly installed on both sides of the die seat and are slidably installed on the linear slide rails. The piston rod of the telescopic cylinder is fixedly connected to the die seat. The upper pressure die is fixedly installed on the die seat. The lower die is fixedly installed on the frame. One guide sleeve is fixedly installed at the middle position of the front end of the lower die. Two screw sleeves are symmetrically and fixedly installed on the left and right sides of the front end of the lower die. The threaded section of the lead screw is screwed into the screw sleeve. The guide sleeve has a guide hole. The cylindrical section at the inner end of the lead screw is slidably installed in the guide hole. The guide wheel is fixedly sleeved on the lead screw. A limit sleeve is also fixedly sleeved on the guide wheel.

[0005] Preferably, a handwheel is fixedly fitted to the outer end of the lead screw.

[0006] Preferably, four guide rods are fixedly installed in a rectangular arrangement on the download mold, and a guide sleeve is fixedly installed on the mold base.

[0007] Preferably, it also includes a carrier plate and a collection bin. The two ends of the carrier plate are rotatably mounted on the frame via a rotating shaft, and the collection bin is fixedly mounted on the carrier plate. A limit lock nut is screwed onto the outer end of the rotating shaft of the carrier plate.

[0008] Compared with existing technologies, the advantages of this invention are: This mechanism uses guide wheels to support the feed of rollable and storeable sheets, and limits the left and right positions of the sheets through limiting sleeves on the guide wheels, thereby improving the accuracy of the punching operation. During sheet feeding, the combination of the guide wheels and limiting sleeves rotates, avoiding wear caused by sliding friction between the sheet and the limiting blocks during feeding. The screw-based adjustment of the guide wheel position offers advantages such as high adjustment accuracy and fast adjustment speed. Attached Figure Description

[0012] The present invention will now be described in detail with reference to specific embodiments:

[0013] like Figure 1 and Figure 2 The mold positioning adjustment mechanism shown includes a frame 1, a telescopic cylinder 2, a mold base 3, an upper pressure mold 31, a linear slide rail 4, a lower mold 5, a lead screw 7, a screw sleeve 72, a guide wheel 8, and a guide sleeve 10. The cylinder body of the telescopic cylinder 2 is fixedly installed on the top of the frame 1. Four linear slide rails 4 are distributed and fixedly installed on the inner walls of the left and right sides of the frame 1 in pairs. Slider blocks are fixedly installed on both sides of the mold base 3, and the sliders are slidably installed on the linear slide rails 4. The piston rod of the telescopic cylinder 2 is fixedly connected to the mold base 3. The upper pressure mold 31 is fixedly installed on the mold base 3. The lower mold 5 is fixedly installed on the frame 1. One guide sleeve 10 is fixedly installed at the middle of the front end of the lower mold 5. Two screw sleeves 72 are symmetrically and fixedly installed on the left and right sides of the front end of the lower mold 5. The threaded section of the lead screw 7 is screwed into the screw sleeve 72. The guide sleeve 10 has a guide hole. The cylindrical section of the inner end of the lead screw 7 is slidably installed in the guide hole. The guide wheel 8 is fixedly sleeved on the lead screw 7. A limit sleeve 81 is also fixedly sleeved on the guide wheel 8.

[0014] A handwheel 71 is fixedly sleeved at the outer end of the lead screw 7, which facilitates the rotation of the lead screw 7.

[0015] Four guide rods 6 are fixedly installed in a rectangular arrangement on the download mold 5. A guide sleeve is fixedly installed on the mold base 3. The upper end of the guide rod 6 is slidably installed in the guide sleeve. The cooperation between the guide rod 6 and the guide sleeve can improve the straightness of the mold base 3 and the upper pressure mold 31 when they move up and down.

[0016] It also includes a carrier plate 9 and a collection bin 91. The two ends of the carrier plate 9 are rotatably mounted on the frame 1 via a rotating shaft. The collection bin 91 is fixedly mounted on the carrier plate 9. A limit lock nut 92 is screwed to the outer end of the rotating shaft of the carrier plate 9. When the limit lock nut 92 is tightened so that its inner end abuts against the frame 1, it can restrict the rotation of the combination of the rotating shaft, the carrier plate 9 and the collection bin 91. After the limit lock nut 92 is loosened, the combination of the rotating shaft, the carrier plate 9 and the collection bin 91 can be rotated to pour out the material received in the collection bin 91.

[0017] The rotating lead screw 7 moves left and right within the screw sleeve 72 to adjust the position of the guide wheel 8. After adjustment, the clamping bolt 101 can be tightened to fix the inner end of the lead screw 7 to the guide sleeve 10, improving stability during use. The rollable and storeable sheet is placed on the guide wheel 8, and the rollable and storeable sheet can be continuously punched. The left and right sides of the sheet are limited by the limiting sleeve 81. The sheet passes through the area between the upper pressure die 31 and the lower pressure die 5. The other end of the sheet is wound up by the winding device. The piston rod of the telescopic cylinder 2 is activated to extend and push the combination of the mold seat 3, the upper pressure die 31 and the slider to move downward along the linear slide rail 4. The upper pressure die 31 and the lower pressure die 5 punch and form the sheet.
