[0004] With respect to the above-mentioned related technologies, the inventor believes that the existing spring piece stamping devices on the market cannot effectively stamp the spring pieces during the stamping process, and the spring pieces cannot be effectively limited during the feeding process, resulting in the spring pieces being skewed, misplaced and deviating from the feeding route, so there is room for improvement. Utility Model Content

[0005] The purpose of the present application is to provide a spring sheet punching device to improve the problem that the spring sheet punching device cannot effectively punch the spring sheet, the spring sheet will be skewed and misplaced and deviate from the feeding route during the feeding process, and the spring sheet cannot be effectively limited during transportation.

[0006] The present application provides a spring sheet punching device that adopts the following technical solution:

[0007] A shrapnel stamping device includes a machine body. One end of the machine body is fixedly provided with an adjusting device. The upper and lower inner walls of the machine body are jointly fixedly provided with a stamping assembly. The stamping assembly includes a support plate. One end of the support plate is fixedly connected to one inner wall of the machine body. The top of the support plate is fixedly connected with three first hollow tubes distributed at equal intervals. The inner walls of the three first hollow tubes are all movably sleeved with hydraulic rods. The tops of the three hydraulic rods are all movably penetrated and connected to the lower inner wall of the machine body. The bottoms of the three hydraulic rods are jointly fixedly connected with a pressing plate. The lower inner wall of the machine body is fixedly connected with a base. One end of the base is fixedly connected with a clamping seat. The bottom end of the clamping seat is fixedly connected to the lower inner wall of the machine body. An upper part of one end of the clamping seat is provided with a placement groove. The top of the base is fixedly connected with a plurality of blocks distributed in a rectangular array. The outer surfaces of the plurality of blocks are all provided with card slots.

[0008] By adopting the above technical solution, when it is necessary to stamp the shrapnel, start the three hydraulic rods inside the machine body. The three hydraulic rods jointly descend to drive the pressing plate to descend. The descent of the pressing plate drives the three sliders to slide on the inner wall of the chute. The descent of the pressing plate drives the four second hollow tubes to descend. The second hollow tubes descend and are forced to squeeze the first spring. The first spring is compressed and deformed under force. The inner wall of the second hollow tube fits with the outer surface of the limiting rod to better limit it. When the four dark bolts are disassembled, the stamping blocks of different models can be replaced, so that different shrapnels can be stamped into different shapes. The descent of the pressing plate drives the stamping block connected to the connecting block to descend. The descent of the stamping block stamps the shrapnel in transportation, thereby achieving the purpose of effectively stamping the shrapnel.

[0009] Optionally, the adjusting device includes a fixed box. One end of the fixed box is fixedly connected to one end of the machine body. Both sides of one end of the fixed box are fixedly connected with connecting plates. One ends of the opposite surfaces of the two connecting plates are jointly fixedly connected with a fixing plate. The top of the fixing plate is provided with a through first through groove. The inner wall of the first through groove is slidably connected with a connecting rod. The bottom end of the connecting rod is fixedly connected with a limiting plate. The outer surface of the connecting rod is movably sleeved with two sliding plates. One ends of the opposite surfaces of the two sliding plates are jointly fixedly connected with a second spring. The inner wall of the second spring fits with the outer surface of the connecting rod. The upper part of the outer surface of the connecting rod is penetrated and connected with a first rotating shaft. Both ends of the first rotating shaft are fixedly connected with a fixed frame. A cam is fixedly sleeved on the outer surface of the first rotating shaft. One end of the fixed frame is fixedly connected with a handle. The outer surface of the connecting rod is movably sleeved with a roller.

[0010] By adopting the above technical solution, the elastic piece is fed into the adjusting device through the feeding device used in cooperation with it. The outer surface of the elastic piece is attached to the outer surfaces of the two driven rods, enters the second through groove opened in the fixed box, passes through the gaps between multiple conveying rollers in sequence, passes through the inner wall of the placing groove, and is attached to the inner wall of the clamping groove in sequence. Since the elastic piece may be skewed, misaligned, and deviate from the feeding route during the feeding process, it is necessary to limit the elastic piece. When adjusting the distance of the sliding roller in the first through groove and adjusting the two rollers to a position suitable for the size of the elastic piece, turn the handle. The rotation of the handle drives the fixed frame to rotate, the rotation of the fixed frame drives the first rotating shaft to rotate, and the rotation of the first rotating shaft drives the two cams to rotate. Since the cams are irregularly shaped, when the cams rotate to 180 degrees, the two cams will squeeze the upper slide plate to move downward. The upper slide plate drives the second spring to be compressed and deformed under force, and the second spring drives the lower slide plate to move slightly downward. The lower slide plate drives the roller to move downward, and the bottom end of the roller is attached to the top end of the fixed plate. In this way, the two rollers can be positioned, so as to achieve the purpose of limiting the elastic piece during transportation and avoiding the situation that the elastic piece is skewed, misaligned, and deviated from the feeding route during the feeding process.

[0011] Optionally, one end of the pressing plate is fixedly connected with three sliders distributed at equal intervals. Sliding grooves for cooperating with the sliders are opened on one inner wall of the machine body. The outer surface of the slider is attached to the inner wall of the sliding groove, and both the slider and the sliding groove are in a "T" shape.

[0012] By adopting the above technical solution, since both the slider and the sliding groove are in a "T" shape, the downward movement of the pressing plate can better drive the three sliders to slide on the inner wall of the sliding groove.

[0013] Optionally, four hidden bolts are inserted through the bottom end of the pressing plate. The top ends of the four hidden bolts are commonly threadedly connected through a connecting block, and a stamping block is fixedly connected to the bottom end of the connecting block.

[0014] By adopting the above technical solution, when the four hidden bolts are disassembled, stamping blocks of different models can be replaced, and thus different elastic pieces can be stamped into different shapes.

[0015] Optionally, the bottom end of the pressing plate is fixedly connected with four second hollow tubes distributed in a rectangular array. Limiting rods are movably sleeved on the inner walls of the four second hollow tubes. The bottom ends of the four limiting rods are fixedly connected to the lower inner wall of the machine body. The outer surfaces of the four limiting rods are movably sleeved with first springs, and the upper and lower ends of the first springs are fixedly connected to the bottom end of the second hollow tube and the lower inner wall of the machine body respectively.

[0016] By adopting the above technical solution, the pressing plate descends to drive the four second hollow tubes to descend. When the second hollow tubes descend, they are forced to squeeze the first springs. The first springs are compressed and deformed under the force, and the inner walls of the second hollow tubes are fitted with the outer surfaces of the limiting rods, thereby better limiting them.

[0017] Optionally, two driven rods are rotatably connected together at one end of the opposite surfaces of the two connecting plates.

[0018] By adopting the above technical solution, during transportation, the outer surface of the elastic piece is fitted with the outer surfaces of the two driven rods, making its transportation more stable.

[0019] Optionally, a through second through groove is opened at one end of the fixed box, and a plurality of transport rollers distributed in a rectangular array are rotatably connected together on the inner walls on both sides of the second through groove.

[0020] By adopting the above technical solution, the elastic piece enters the second through groove opened in the fixed box and passes through the gaps between the plurality of transport rollers in sequence, making the transportation of the elastic piece more effective.

[0021] Optionally, two brackets are fixedly connected to both sides of the bottom end of the fixed box, and one ends of the two brackets are fixedly connected to one end of the machine body together.

[0022] By adopting the above technical solution, the two brackets can stably fix the fixed box at one end of the machine body.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. In the present utility model, the pressing plate descends to drive the stamping block connected to the connecting block to descend, and the stamping block descends to stamp the elastic piece during transportation, thereby achieving the purpose of effectively stamping the elastic piece;

[0025] 2. In the present utility model, the two cams squeeze the upper skateboard to move downward, which can position the two rollers, thereby achieving the purpose of limiting the elastic piece during transportation and avoiding the situation that the elastic piece is skewed, misaligned, or deviated from the feeding route during the feeding process.

Specific embodiments

[0033] The following will further elaborate on this application in conjunction with the attached Figure 1 - attached Figure 6 , with further details.

[0034] Embodiment

[0035] A shrapnel stamping device includes a body 1. One end of the body 1 is fixedly provided with an adjusting device 3. The upper and lower inner walls of the body 1 are jointly and fixedly provided with a stamping assembly 2. The adjusting device 3 can limit the position of the shrapnel during transportation to prevent the shrapnel from skewing, misaligning, or deviating from the feeding route during the feeding process. The stamping assembly 2 can effectively stamp the shrapnel;

[0036] The stamping assembly 2 includes a support plate 201, a first hollow tube 202, a slider 205 and a stamping block 209. One end of the support plate 201 is connected to the inner wall of one side of the machine body 1 by welding. Three equally spaced first hollow tubes 202 are fixedly connected to the top end of the support plate 201. Three hydraulic rods 203 are respectively located in the inner walls of the first hollow tubes 202. The bottom ends of the three hydraulic rods 203 are jointly welded to a pressure plate 204. One end of the pressure plate 204 is connected to three equally spaced sliders 205 by welding. Chutes 206 for cooperating with the sliders 205 are provided on the inner walls of one side of the machine body 1. The outer surface of the slider 205 is fitted with the inner wall of the chute 206. Both the slider 205 and the chute 206 are in a "T" shape. Due to the "T" shape of both the slider 205 and the chute 206, the downward movement of the pressure plate 204 can better drive the three sliders 205 to slide in the inner walls of the chutes 206;

[0037] Four hidden bolts 208 are inserted through the bottom end of the pressure plate 204 by bolts. The top ends of the four hidden bolts 208 are jointly threadedly connected through a connecting block 207. The bottom end of the connecting block 207 is connected to the stamping block 209 by welding. When the four hidden bolts 208 are removed, stamping blocks 209 of different models can be replaced, and thus different-shaped elastic sheets can be stamped into different shapes;

[0038] Four second hollow tubes 210 are welded to the bottom end of the pressure plate 204 in a rectangular array. Limiting rods 211 are movably sleeved in the inner walls of the four second hollow tubes 210. The bottom ends of the four limiting rods 211 are connected to the lower inner wall of the machine body 1 by welding. First springs 212 are movably sleeved on the outer surfaces of the four limiting rods 211. The upper and lower ends of the first springs 212 are respectively connected to the bottom end of the second hollow tube 210 and the lower inner wall of the machine body 1 by welding. The downward movement of the pressure plate 204 drives the four second hollow tubes 210 to descend. The downward movement of the second hollow tubes 210 forces the first springs 212 to be compressed. The first springs 212 are compressed and deformed. The inner wall of the second hollow tube 210 is fitted with the outer surface of the limiting rod 211 to better limit it;

[0039] A base 213 is welded to the lower inner wall of the machine body 1. A clamping seat 214 is provided at one end of the base 213. The bottom end of the clamping seat 214 is connected to the lower inner wall of the machine body 1 by welding. A placement groove 215 is provided in the upper part of one end of the clamping seat 214. A plurality of clamping blocks 216 are fixedly connected to the top end of the base 213 in a rectangular array. Card slots 217 are provided on the outer surfaces of the plurality of clamping blocks 216. The elastic sheet passes through the inner wall of the placement groove 215 and is successively fitted with the inner wall of the card slot 217. Since the elastic sheet may be skewed, misaligned and deviated from the feeding route during the feeding process, it is necessary to limit the elastic sheet;

[0040] The adjusting device 3 includes a fixed box 301, a limiting plate 306, a second spring 308 and a bracket 318. One end of the fixed box 301 is connected to one end of the machine body 1 by welding. On both sides of one end of the fixed box 301, connecting plates 302 are welded. At one end of the opposite surfaces of the two connecting plates 302, a fixed plate 303 is jointly welded. At the top end of the fixed plate 303, a through first through groove 304 is opened. The inner wall of the first through groove 304 is slidably connected with a connecting rod 305. The bottom end of the connecting rod 305 is connected to the limiting plate 306 by welding. The connecting rod 305 slides on the inner wall of the first through groove 304 to adjust the appropriate distance from the elastic sheet.

[0041] Two sliding plates 307 are movably sleeved on the outer surface of the connecting rod 305. At one end of the opposite surfaces of the two sliding plates 307, the upper and lower ends of a second spring 308 are jointly connected by welding. The second spring 308 is located on the outer surface of the connecting rod 305. The upper part of the outer surface of the connecting rod 305 is connected through a first rotating shaft 309. Both ends of the first rotating shaft 309 are fixedly connected with a fixed frame 310. A cam 311 is fixedly sleeved on the outer surface of the first rotating shaft 309. One end of the fixed frame 310 is welded with a handle 312. A roller 313 is movably sleeved on the outer surface of the connecting rod 305. By rotating the handle 312, the handle 312 drives the fixed frame 310 to rotate. The fixed frame 310 drives the first rotating shaft 309 to rotate. The first rotating shaft 309 drives the two cams 311 to rotate. Since the cam 311 is of an irregular shape, when the cam 311 rotates to 180 degrees, the two cams 311 will squeeze the upper sliding plate 307 to move downward. The upper sliding plate 307 drives the second spring 308 to be compressed and deformed under force. The second spring 308 drives the lower sliding plate 307 to move slightly downward. The lower sliding plate 307 drives the roller 313 to move downward. The bottom end of the roller 313 is in contact with the top end of the fixed plate 303, so that the two rollers 313 can be positioned.

[0042] At one end of the opposite surfaces of the two connecting plates 302, two driven rods 315 are jointly rotatably connected. A through second through groove 316 is opened at one end of the fixed box 301. On the inner walls of both sides of the second through groove 316, a plurality of conveying rollers 317 distributed in a rectangular array are jointly rotatably connected. On both sides of the bottom end of the fixed box 301, two brackets 318 are connected by welding. One end of the two brackets 318 is jointly connected to one end of the machine body 1 by welding. During the transportation of the elastic sheet, the outer surface of the elastic sheet is in contact with the outer surfaces of the two driven rods, making the transportation more stable. The elastic sheet enters the second through groove 316 opened in the fixed box 301 and sequentially passes through the gaps between the plurality of conveying rollers 317, making the transportation of the elastic sheet more effective. The two brackets 318 can stably fix the fixed box 301 at one end of the machine body 1.

[0043] Working principle: The shrapnel is fed into the adjusting device 3 through the feeding device used in cooperation with it. The outer surface of the shrapnel fits against the outer surfaces of the two driven rods 315, enters the second through groove 316 opened in the fixed box 301, passes through the gaps between multiple transport rollers 317 in sequence, passes along the inner wall of the placement groove 215, and fits against the inner walls of the card slots 217 in sequence. Since the shrapnel may be skewed, misaligned, or deviated from the feeding route during the feeding process, it is necessary to limit the position of the shrapnel. Slide the distance of the sliding roller 313 in the first through groove 304. When the two rollers 313 are adjusted to a position suitable for the size of the shrapnel, turn the handle 312. The rotation of the handle 312 drives the rotation of the fixed frame 310. The rotation of the fixed frame 310 drives the rotation of the first rotating shaft 309. The rotation of the first rotating shaft 309 drives the rotation of the two cams 311. Since the cams 311 are irregular in shape, when the cams 311 rotate to 180 degrees, the two cams 311 will squeeze the upper slide plate 307 to move downward. The upper slide plate 307 is stressed to drive the second spring 308 to be compressed and deformed. The second spring 308 drives the lower slide plate 307 to move slightly downward. The lower slide plate 307 drives the roller 313 to move downward. The bottom end of the roller 313 fits against the top end of the fixed plate 303. In this way, the two rollers 313 can be positioned, so as to achieve the purpose of limiting the shrapnel during transportation and avoiding the situation that the shrapnel is skewed, misaligned, or deviated from the feeding route during the feeding process;

[0044] When it is necessary to punch the shrapnel, start the three hydraulic rods 203 inside the machine body 1. The three hydraulic rods 203 descend together to drive the pressing plate 204 to descend. Since both the slider 205 and the chute 206 are in a "T" shape, the descent of the pressing plate 204 can better drive the three sliders 205 to slide on the inner wall of the chute 206. The descent of the pressing plate 204 drives the four second hollow tubes 210 to descend. The descent of the second hollow tubes 210 forces the first spring 212 to be compressed and deformed. The inner wall of the second hollow tube 210 fits against the outer surface of the limiting rod 211 to better limit it. When the four hidden bolts 208 are removed, the punching blocks 209 of different models can be replaced, so that different shrapnels can be punched into different shapes. The descent of the pressing plate 204 drives the punching block 209 connected to the connecting block 207 to descend. The descent of the punching block 209 punches the shrapnel during transportation, thus achieving the purpose of effectively punching the shrapnel.
