Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, specifically relating to an adjustment device for adjusting the height of the forming inclined block of the upper die base of a stamping die. Background Technology

[0002] Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts. Stamping dies are special process equipment used in stamping to process materials (metal or non-metal) into parts (or semi-finished products). According to the nature of the process, stamping dies are classified into several categories such as blanking dies, bending dies, drawing dies, forming dies, and riveting dies. Bending dies are dies that cause sheet metal blanks or other blanks to bend along a straight line (bending line) to obtain workpieces with a certain angle and shape. Bending dies usually use height-adjustable forming skew blocks to achieve the bending deformation of products.

[0003] Existing bending molds Figure 1 As shown, the height of the shaping inclined block 1 is mostly adjusted by adjusting bolt 2 and then locked by locking nut 3. The adjusting bolt 2 is located directly above the shaping inclined block 1. The height is adjusted by pushing the shaping inclined block 1 with the thread. The upper end of the bolt and the locking nut 3 are mostly located on one side near the upper surface of the upper mold base 4. The upper surface of the upper mold base 4 is mostly connected to functional plates, which will block the upper end of the adjusting bolt 2 and the locking nut 3. During adjustment, the upper mold base 4 needs to be removed, and then the adjusting bolt 2 and the locking nut 3 are rotated and loosened or tightened by tools such as socket wrench and Allen wrench to change the downward pressing distance of the shaping inclined block 1, so as to adjust the bending angle of the product. After adjustment, the upper mold base 4 needs to be installed to test the effect. If it is not adjusted to the correct position, the upper mold base 4 needs to be repeatedly removed and installed for adjustment until the product angle is qualified. The adjustment efficiency is very low. Utility Model Content

[0025] In this utility model, the up / down and front / back directions refer to... Figure 2 The up, down, left, and right directions.

[0026] like Figure 2 and Figure 3As shown, the adjustment device for adjusting the height of the forming inclined block of the upper die base of a stamping die provided by this utility model includes a forming inclined block 1 that is movably disposed in the upper die base 4, an inner adjusting screw 6 disposed in the upper die base 4 and located directly above the forming inclined block 1, and a return spring 7 disposed in the upper die base 4 for driving the forming inclined block 1 to reset; wherein, the lower end of the inner adjusting screw 6 abuts against the upper end of the forming inclined block 1, and the inner adjusting screw 6 is also threadedly connected to the upper die base 4; the upper die base 4 is provided with a horizontal cavity 8, water The inner end of the flat cavity 8 extends to the upper end of the inner adjusting screw 6, and the outer end penetrates the front side wall of the upper mold base 4. The front side wall of the upper mold base 4 is connected to a rotatable outer adjusting bolt 9. The outer adjusting bolt 9 is connected to the upper end of the inner adjusting screw 6 through a transmission assembly 10 located in the horizontal cavity 8. When the outer adjusting bolt 9 rotates, it can drive the inner adjusting screw 6 to rotate through the transmission assembly 10. The height of the shaping inclined block 1 is adjusted by the up-and-down movement of the inner adjusting bolt 6 relative to the upper mold base 4.

[0027] The advantage of this design is that the force application position during adjustment can be moved to the front of the upper mold base through the cooperation of the transmission components, the internal adjusting screw, and the external adjusting bolt. There is no obstruction, and the adjustment can be carried out without disassembling the upper mold base, resulting in high adjustment efficiency.

[0028] In this embodiment, the upper surface of the upper mold base 4 is provided with a groove 11, and a cover plate 12 is provided on the groove 11. The upper surface of the cover plate 12 is flush with the upper surface of the upper mold base 4. The cavity formed by the cover plate 12 and the groove 11 constitutes a part of the horizontal cavity 8. In order to facilitate maintenance, the cover plate 12 covers part of the groove opening of the groove 11.

[0029] For ease of connection, in this embodiment, the front side wall of the upper mold base 4 is provided with a support 13 for installing the external adjusting bolt 9. The external adjusting bolt 9 is movably mounted on the support 13. Specifically, the support 13 is L-shaped and includes a vertically connected vertical plate 14 and a horizontal plate 15. The vertical plate 14 is connected to the front side wall of the upper mold base 4, and the horizontal plate 15 extends forward horizontally. The external adjusting bolt 9 is vertically mounted on the horizontal plate 15 and threadedly connected to the horizontal plate 15. The screw head 16 of the external adjusting bolt 9 is located below the horizontal plate 15.

[0030] To prevent loosening, a tightening bolt 16 is further provided on the horizontal plate 15 to abut against the external adjusting bolt 9 in the front-back direction. The tightening bolt 16 is threadedly connected to the horizontal plate 15, and the head of the tightening bolt 16 protrudes from the front side wall of the horizontal plate 15.

[0031] In this embodiment, the transmission ratio of the transmission assembly 10 is 1:1 (in order to more precisely adjust the height of the shaping inclined block 1, in other embodiments, the transmission ratio of the transmission assembly 10 can also be 0.8:1 or 0.9:1, etc., which can be selected according to the requirements). The transmission assembly 10 is a synchronous belt transmission assembly in the belt transmission assembly. Specifically, the transmission assembly 10 includes an inner synchronous pulley 17 connected to the inner adjusting screw 6, an outer synchronous pulley 18 connected to the outer adjusting bolt 9, and a synchronous belt 19 tensioned on the inner synchronous pulley 17 and the outer synchronous pulley 18.

[0032] After testing, it was found that... Figure 1 The existing adjustment device for adjusting the height of the forming inclined block takes an average of 425 seconds per adjustment (including the time spent on multiple disassembly and reassembly of the upper mold base). However, the adjustment device provided by this invention, which does not require disassembly and reassembly of the upper mold base, takes an average of only about 40 seconds per adjustment. It is more convenient to operate and the time consumption is significantly reduced compared to other methods. Figure 1 The existing technology shown has reduced production capacity by more than 90%, saving the factory capacity and improving production efficiency.

Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
