Description

Technical Field

[0001] This utility model relates to the field of stamping die technology for metal products, and in particular to a stamping die for metal products. Background Technology

[0002] A stamping die is a special piece of equipment used in cold stamping to process materials into parts. Stamping is a pressure processing method that uses a die mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts.

[0003] The original mold may have a slight deviation in the relative position of the upper and lower mold bases. During the mold closing process, the guide pillar and guide sleeve may collide. Due to the fast mold closing speed, a large impact will be generated, which will make the spring on the guide pillar bear a large force. The continuous impact will increase the fatigue wear of the spring.

[0004] This utility model was developed based on the above-mentioned shortcomings. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of the prior art and provide a stamping die capable of producing slow-moving metal products.

[0006] To achieve the above objectives, the present invention adopts the following solution:

[0007] A stamping die for metal products, comprising:

[0008] The upper mold assembly includes an upper template and a first mold core and a second mold core disposed on the upper template, wherein the first mold core and the second mold core are spaced apart.

[0009] The lower mold assembly includes a lower template, on which a first template is provided that can be adapted to the position of a first mold core, and the lower mold assembly is also provided with a second template that can be adapted to the position of a second mold core.

[0010] A buffer assembly is disposed between an upper template and a lower template. The buffer assembly includes multiple pressing blocks disposed on the upper template. The pressing blocks are spaced apart at the four corners of the upper template, and the two pressing blocks located at the same corner are arranged at right angles. The lower template is provided with a sliding groove that can be adapted to the position of each pressing block. A slider that can slide relative to the sliding groove is provided in each sliding groove. The slider is provided with a limiting part that can prevent it from disengaging from the sliding groove. The lower template is also provided with a limiting groove that allows the limiting part to move within it. The bottom of the slider is provided with a groove that can cooperate with the limiting groove to form a pneumatic spring cavity. The lower template is provided with a through groove that can communicate with the sliding groove.

[0011] Each of the aforementioned top pressing blocks is provided with protruding protrusions.

[0012] The lower template includes a base plate and a first support plate spaced apart. Multiple connecting plates are provided between the first support plate and the base plate to connect the two. A lower plate body is provided on the first support plate. The lower plate body is provided with the sliding groove. The first support plate is provided with a top surface that can prevent the slider from disengaging from the sliding groove. The limiting groove is provided on the first support plate. The slider is provided between the first support plate and the lower plate body.

[0013] The diameter of the through groove is smaller than the diameter of the slide groove.

[0014] A positioning component is provided between the upper template and the lower plate. The positioning component includes positioning grooves spaced around the upper template and extending from the side of the upper template toward the center. The lower plate is provided with positioning blocks that can be adapted to the positioning grooves.

[0015] A locking assembly is also provided between the lower plate and the first support plate.

[0019] The lower plate is also provided with a positioning post that can pass through the middle of the second template.

[0020] Compared with existing technologies, this utility model has the following advantages: When processing sheet metal, the sheet metal is placed on the lower template. At this time, the external pneumatic equipment injects gas into the through groove, causing the slider to reach the preset position. The press starts, causing the upper die assembly to move downward and the lower die assembly to cooperate in stamping the sheet metal. During the downward movement of the upper die assembly, the top pressure block gradually contacts the slider. The groove and limit groove of the slider are filled with gas, which acts as a pneumatic spring, making the downward stamping of the upper die assembly smoother. After reaching the preset stamping position, the upper die assembly moves in the opposite direction. The user takes out the stamped sheet metal and then repeats the above process. The cooperation of the groove and limit groove of the slider forms a pneumatic spring, which can be reused. Compared with metal springs, it is lower in cost and more convenient to use.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to embodiments:

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] like Figures 1 to 5 As shown, a stamping die for metal products includes: an upper die assembly 1, which includes an upper template 11 and a first die core 12 and a second die core 13 disposed on the upper template 11, the first die core 12 and the second die core 13 being spaced apart; a lower die assembly 2, which includes a lower template 21, the lower template 21 being provided with a first template 22 that can be adapted to the position of the first die core 12, the lower die assembly 2 also being provided with a second template 23 that can be adapted to the position of the second die core 13; and a buffer assembly 3, which is disposed between the upper template 11 and the lower template 21, the buffer assembly 3 including a plurality of pressing blocks 31 disposed on the upper template 11, the plurality of pressing blocks 31 being spaced apart. Top pressure blocks 31 are spaced apart at the four corners of the upper template 11, with two top pressure blocks 31 located at the same corner at right angles. The lower template 21 is provided with sliding grooves 32 that can adapt to the positions of each top pressure block 31. Each sliding groove 32 is provided with a slider 33 that can slide relative to it. The slider 33 is provided with a limiting part 331 that can prevent it from disengaging from the sliding groove 32. The lower template 21 is also provided with a limiting groove 211 that allows the limiting part 331 to move within it. The bottom of the slider 33 is provided with a groove 332 that can cooperate with the limiting groove 211 to form a pneumatic spring cavity 212. The lower template 21 is provided with a through groove 213 that can communicate with the sliding grooves 32. An external pneumatic device is connected to the lower template 21 by injecting gas through the through groove 213.

[0030] When the sheet metal needs to be processed, the sheet metal is placed on the lower die plate 21. At this time, the external pneumatic equipment injects gas into the through groove 213, causing the slider 33 to reach the preset position. The press starts, causing the upper die assembly 1 to move downward and the lower die assembly 2 to cooperate in stamping the sheet metal. During the downward movement of the upper die assembly 1, the top pressing block 31 gradually contacts the slider 33. The groove 332 and the limiting groove 211 of the slider 33 are filled with gas, which is used as a pneumatic spring, making the downward stamping of the upper die assembly 1 smoother. After reaching the preset stamping position, the upper die assembly 1 moves in the opposite direction. The user takes out the stamped sheet metal and then repeats the above process. The cooperation of the groove 332 and the limiting groove 211 of the slider 33 forms a pneumatic spring, which can be reused. Compared with metal springs, it is lower in cost and more convenient to use.

[0031] Each of the aforementioned top pressing blocks 31 is provided with a protruding protrusion 311. The protruding part of the protrusion 311 can contact the slider 33 first, and has sufficient stroke to process the plate, avoiding direct collision between each mold core and the template, thus preventing damage to the stamping die.

[0032] The lower template 21 includes a base plate 214 and a first support plate 215 spaced apart. Multiple connecting plates 216 connect the first support plate 215 and the base plate 214. A lower plate body 217 is mounted on the first support plate 215, and the lower plate body 217 has the aforementioned sliding groove 32. The first support plate 215 has a top abutment surface 2151 that prevents the slider 33 from disengaging from the sliding groove 32. A limiting groove 211 is located on the first support plate 215, and the slider 33 is positioned between the first support plate 215 and the lower plate body 217. The separate design of the first support plate 215 and the lower plate body 217 facilitates the machining of the limiting groove 211 and the sliding groove 32, and also facilitates positioning and installation. They can be replaced separately when the stamping die is damaged, and the separate connection facilitates the installation of the slider 33.

[0033] The diameter of the through groove 213 is smaller than the diameter of the slide groove 32, which can prevent the slider 33 from sliding out of the through groove 213.

[0034] A positioning component 4 is provided between the upper template 11 and the lower plate 217. The positioning component 4 includes positioning grooves 41 spaced around the upper template 11. The positioning grooves 41 extend from the side of the upper template 11 toward the center. The lower plate 217 is provided with positioning blocks 42 that can be adapted to the positioning grooves 41.

[0035] A locking component 5 is also provided between the lower plate 217 and the first support plate 215. The locking component 5 includes a through hole 51 on the lower plate 217, and a locking block 52 connected to the first support plate 215, which passes through the through hole 51. The locking block 52 is provided with a protruding hook 53 that abuts against the upper surface 2170 of the lower plate 217. The hook 53 abuts against the upper surface 2170 of the lower plate 217, enabling the lower plate 217 and the first support plate 215 to be locked together.

[0036] The locking block 52 has a protruding hook 53 on one side, giving this side a second abutting surface 521. The lower plate 217 is also provided with a locking block 54 that can be connected to the locking block 54 and abut against the second abutting surface 521. When the locking block 54 is connected to the lower plate 217 by screws, the bottom surface of the locking block 54 can abut against the second abutting surface 521 to prevent the locking block 52 from disengaging.

[0037] Multiple positioning blocks 218 are provided on the four sides of the adjacent lower plate 217, and the positioning blocks 218 are locked to the lower plate 217 by screws. The positioning blocks 218 can cooperate with the locking assembly 5 to form a double lock, making the lock more secure.

[0038] The inner side of the positioning block 218 on the same side is also provided with a strip-shaped stamping block 219, and part of the strip-shaped stamping block 219 protrudes to the upper surface 2170 of the lower plate 217. The strip-shaped stamping block 219 is not only used for positioning, but also for stamping out strip grooves on the plate.

[0039] The lower plate 217 is also provided with a positioning post 21a that can pass through the middle of the second template 23. The positioning post 21a facilitates the positioning and installation of the second template 23. At the same time, the top surface of the positioning post 21a is arc-shaped, which makes it easy to punch an arc-shaped groove on the plate.

[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
