Description

Technical Field

[0001] The invention relates to the technical field of stamping, in particular to an installation structure for clamping a die. Background Art

[0002] A stamping die is a special process equipment that processes materials into parts (or semi-finished products) during cold stamping. Existing stamping dies are mostly fixed directly with flanges or bolts when in use. When installing or disassembling the stamping die, multiple bolts need to be repeatedly rotated in sequence, which has high work intensity and reduces the work efficiency of the staff. The thickness of the mold (surface thickness, main rib thickness, auxiliary rib thickness, etc.) is generally designed to be above 50mm. However, if the project is a trial production or a small batch with a small output, using this thick mold will cause a lot of waste, so the mold thickness needs to be reduced, but too much thinning will affect the mold strength. In order to find the relationship between the mold service life and the mold design thickness, a large number of mold processing tests are required.

[0003] The patent application with publication number CN112275916A discloses a die installation mechanism for stamping automobile parts, including a mounting plate, a first fixing plate and a second fixing plate are fixedly connected to the mounting plate, a die is arranged between the first fixing plate and the second fixing plate; a push rod is arranged on the first fixing plate, a receiving hole is provided at one end of the push rod close to the die, a telescopic rod is slidably connected in the receiving hole, a first compression spring is arranged in the receiving hole, a clamping block is fixedly connected at one end of the telescopic rod, a first support rod is rotatably connected to the clamping block, a second support rod is rotatably connected to the side wall of the push rod, and an end of the second support rod away from the push rod is rotatably connected to the middle part of the first support rod; a first groove is provided on one side of the die, the clamping block abuts against the side wall of the first groove, and one end of the first support rod abuts against the bottom of the first groove.

DETAILED DESCRIPTION

[0031] The following will be combined with the attached Figures 1 to 9 The technical solution of the present invention is described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The present invention provides a mounting structure for clamping a mold by improving the Figure 1-Figure 9As shown, the stamping device 1 and the detachable stamping die 2 are included. The stamping device 1 includes a stamping table 101, and a die cavity 102 cooperating with the stamping die 2 is provided on the stamping table 101; a stamping cavity 202 is provided on the top of the stamping die 2, and a vertical mounting cavity 203 is provided inside the stamping die 2, and a meshing cavity 1 205 and a meshing cavity 207 coaxially arranged with the mounting cavity 203 are also provided inside the stamping die 2, and a sliding cavity 1 206 connected to the meshing cavity 1 205 is provided on both sides, and a sliding cavity 208 connected to the meshing cavity 207 is provided on both sides; a ball threaded rod 211 is installed in the mounting cavity 203, and a linkage gear 213 cooperating with the ball threaded rod 211 is rotatably provided in the meshing cavity 1 205. A linkage sleeve 218 cooperating with the ball threaded rod 211 is rotatably arranged in the meshing cavity 207; a locking strip 214 meshing with the linkage gear 213 is slidably arranged in the sliding cavity 1 206; an inner sliding arm 221 and an outer sliding arm 223 are slidably arranged in the sliding cavity 208; a first magnetic plate 222 is arranged on the outer side of the inner sliding arm 221, and a second magnetic plate 226 is arranged on the side of the outer sliding arm 223 close to the inner sliding arm 221; an extrusion insert plate 232 located on the outer side of the stamping die 2 is also movably arranged in the stamping cavity 202; when the ball threaded rod 211 is squeezed by the extrusion insert plate 232 and moves inward along the mounting cavity 203, the locking strip 214 and the outer sliding arm 223 pop out to both sides and lock the die cavity 102.

[0033] In this embodiment: the installation structure of the clamping die is mainly divided into two parts: the stamping device 1 and the stamping die 2. When the device is used, the stamping die 2 is first installed. During installation, the T-shaped seats 201 on both sides of the stamping die 2 slide inward along the T-shaped slots 103 on both sides of the die cavity 102, and then the extrusion plug plate 232 is installed. After the stamping die 2 is installed, the pull ring 113 is released. At this time, under the action of the locking spring 112, the plug block 111 and the connecting rod 110 automatically pop out and insert into the positioning groove 234. When the extrusion part 212 is squeezed, the ball thread rod 211 is squeezed and moves vertically downward along the installation cavity 203. Under the clockwise drive of the linkage gear 213, the locking strips 214 on both sides will move outward along the sliding cavity 1 206 and insert into the inner locking groove 104. And under the drive of the linkage sleeve 218 and the linkage rod 220, the inner sliding arm 221 will slide outward. Since the first magnetic plate 222 and the second magnetic plate 226 have the same magnetic properties, the repulsive force between the first magnetic plate 222 and the second magnetic plate 226 is greater than the elastic force of the return spring 1 225, so the outer sliding arm 223 will move outward along the sliding cavity 208 and insert into the outer locking groove 105. After the stamping is completed, the cylinder 117 drives the output shaft 118 to move upward. At this time, under the linkage of the first swing arm 122 and the second swing arm 123, the support arm 124 and the roller brush 125 will move upward and clean the bottom of the stamping plate 119. The debris on the stamping plate 119 after cleaning will fall into the stamping cavity 202 below, and the debris will enter the dust suction pump 114 through the upper dust suction channel 230 and the lower dust suction channel 106 in turn.

[0034] See attached Figure 2 and attached Figure 4 T-shaped slots 103 are provided on both sides of the mold cavity 102, and T-shaped seats 201 matching therewith are provided on the outer walls of both sides of the stamping mold 2; an extrusion portion 212 is provided on the top of the ball thread rod 211, and a receiving portion 204 matching therewith is provided on the top of the installation cavity 203.

[0035] In this embodiment, when the extrusion part 212 is extruded, in order to store it, a storage part 204 is designed. In order to quickly install and position the stamping die 2, a T-slot 103 and a T-seat 201 structure are designed.

[0036] See attached Figure 6 -Attached Figure 8A symmetrical swing seat 219 is arranged on the outer wall of the linkage sleeve 218, and a linkage rod 220 is movably arranged between the swing seat 219 and the inner sliding arm 221; reset grooves 209 are opened on the inner walls of both sides of the sliding cavity 208, and convex plates 224 are arranged on the outer walls of both sides of the outer sliding arm 223, and multiple groups of reset springs 225 are arranged on the inner side of the convex plate 224, and the convex plate 224 is connected to the inner wall of the reset groove 209 through the reset spring 225; the first magnetic plate 222 and the second magnetic plate 226 have the same magnetic properties.

[0037] In this embodiment: when the extrusion portion 212 is extruded, the ball screw rod 211 is extruded and moves vertically downward along the installation cavity 203. Under the clockwise drive of the linkage gear 213, the locking strips 214 on both sides will move outward along the sliding cavity 1 206 and insert into the inner locking groove 104. And under the drive of the linkage sleeve 218 and the linkage rod 220, the inner sliding arm 221 will slide outward. Since the first magnetic plate 222 and the second magnetic plate 226 have the same magnetic properties, the repulsive force between the first magnetic plate 222 and the second magnetic plate 226 is greater than the elastic force of the reset spring 1 225, so the outer sliding arm 223 will move outward along the sliding cavity 2 208 and insert into the outer locking groove 105. In order to control the locking and unlocking of the outer sliding arm 223 by adjusting the magnitude of the repulsive force between the inner sliding arm 221 and the outer sliding arm 223, the magnetic properties of the first magnetic plate 222 and the second magnetic plate 226 are made the same.

[0038] See attached Figure 2 -Attached Figure 5 Symmetrical positioning grooves 234 are provided on the outer walls of both sides of the extrusion plug plate 232, a locking cavity 107 cooperating with the extrusion plug plate 232 is provided on the inner wall of the mold cavity 102, and a through hole 108 is provided on the inner wall of the locking cavity 107; a plug-in 109 is movably installed in the locking cavity 107, and the plug-in 109 includes a plug-in block 111 movably arranged in the locking cavity 107, and a connecting rod 110 movably arranged in the through hole 108 is fixedly arranged on the outer side of the plug-in block 111. A locking spring 112 is sleeved on the outer side of the connecting rod 110, a pull ring 113 is provided on the outer wall of the plug-in 109, and a handle 233 is also provided on the outer side of the extrusion plug plate 232.

[0039] In this embodiment, when the stamping die 2 needs to be replaced, the pull ring 113 is first stretched to both sides. When the insert block 111 is separated from the positioning groove 234, the extrusion insert plate 232 is pulled outward through the handle 233. After the stamping die 2 is replaced, the extrusion insert plate 232 is installed on the outside thereof, and then the pull ring 113 is released. At this time, under the action of the locking spring 112, the insert block 111 and the connecting rod 110 are automatically ejected and inserted into the positioning groove 234.

[0040] See attached Figure 2 and attached Figure 7 -Attached Figure 8 The locking bar 214 is provided with a meshing portion 215 that cooperates with the linkage gear 213, and symmetrical sliding grooves 217 are provided on the upper and lower inner walls of the sliding cavity 206, and protrusions 216 that cooperate with it are provided on the upper and lower outer walls of the locking bar 214; the inner walls on both sides of the mold cavity 102 are provided with inner locking grooves 104 that cooperate with the locking bar 214 and outer locking grooves 105 that cooperate with the outer sliding arm 223.

[0041] In this embodiment, in order to further improve the stability of the locking strip 214 when sliding, a sliding groove 217 and a protrusion 216 structure are designed.

[0042] See attached Figure 1 and attached Figure 4 A top plate 116 is fixedly provided on the top of the stamping table 101, and a cylinder 117 is installed on the top plate 116. The cylinder 117 includes an output shaft 118, and a stamping plate 119 that cooperates with the stamping cavity 202 is detachably installed on the bottom of the output shaft 118; symmetrical upper mounting seats 120 are provided on both sides of the top plate 116, and lower mounting seats 121 are provided on both sides of the output shaft 118. A first swing arm 122 is movably installed on the upper mounting seat 120, and a second swing arm 123 is movably installed between the bottom of the first swing arm 122 and the lower mounting seat 121. A support arm 124 located below the stamping plate 119 is provided on the outer wall of the second swing arm 123, and a plurality of groups of roller brushes 125 are movably installed on the support arm 124.

[0043] In this embodiment: after the stamping is completed, the cylinder 117 drives the output shaft 118 to move upward, and at this time, under the linkage of the first swing arm 122 and the second swing arm 123, the support arm 124 and the roller brush 125 will move upward and clean the bottom of the stamping plate 119. When stamping, the cylinder 117 drives the output shaft 118 to move downward, and at this time, under the linkage of the first swing arm 122 and the second swing arm 123, the support arm 124 and the roller brush 125 move downward and deflect to both sides, and will not interfere with the stamping operation.

[0044] See attached Figure 1 -Attached Figure 4 The stamping die 2 is provided with a plurality of upper dust suction channels 230 passing therethrough, the stamping table 101 is provided with a lower dust suction channel 106 cooperating therewith, a dust suction pump 114 is also installed at the bottom of the stamping table 101, and a filter screen 231 is installed at the inlet of the upper dust suction channel 230.

[0045] In this embodiment, during the stamping process, debris will be generated on both sides of the parts, that is, the bottom of the stamping plate 119 and the inside of the stamping cavity 202. The debris on the stamping plate 119 after cleaning will fall into the stamping cavity 202 below, and the debris will enter the dust suction pump 114 through the upper dust suction channel 230 and the lower dust suction channel 106 in turn.

[0046] See attached Figure 6 and attached Figure 8 A second return spring 227 is also provided at the bottom of the installation cavity 203, and the ball threaded rod 211 is connected to the top of the second return spring 227; a rotation groove 228 is provided on the upper and lower sides of the linkage sleeve 218, and an annular rail 229 matching with it is provided on the upper and lower inner walls of the second engagement cavity 207.

[0047] In this embodiment, when the stamping die 2 is disassembled, in order to automatically reset the ball screw rod 211, the ball screw rod 211 is connected to the bottom of the installation cavity 203 through the reset spring 227. When the extrusion plug plate 232 is removed, the ball screw rod 211 is restored to its original state under the action of the reset spring 227. Since the linkage gear 213 and the linkage sleeve 218 are both threadedly connected to the ball screw rod 211, the locking bars 214 on both sides will move inward along the sliding cavity 1 206 and disengage from the inner locking groove 104 under the counterclockwise drive of the linkage gear 213. And under the counterclockwise rotation of the linkage sleeve 218 and the drive of the linkage rod 220, the inner sliding arm 221 will slide inward. Since the first magnetic plate 222 and the second magnetic plate 226 have the same magnetic properties, the repulsive force between the first magnetic plate 222 and the second magnetic plate 226 is less than the elastic force of the reset spring 1 225, so the outer sliding arm 223 moves inward along the sliding cavity 208 and disengages from the outer locking groove 105. In order to install the linkage sleeve 218 and ensure that it swings back and forth relative to the meshing cavity 207, a rotating groove 228 and an annular rail 229 structure that cooperate with each other are designed. When squeezed, in order to ensure that the ball screw rod 211 moves vertically and does not rotate relative to the installation cavity 203, a limit groove and a limit block structure (not shown) are designed in the squeezing portion 212 and the receiving portion 204.

[0048] See attached Figure 1 -Attached Figure 2 A plurality of reinforcing ribs 210 are arranged on the outer wall of the punching cavity 202 , and a conveyor belt 115 is also arranged on the side of the punching platform 101 .

[0049] In this embodiment, in order to further improve the strength of the punching cavity 202 and avoid deformation after long-term use, thereby affecting the precision of the parts, a reinforcing rib 210 is designed. In order to facilitate the conveying of the punched parts to the next process, a conveyor belt 115 is designed.

[0050] Working principle of the present invention: When the device is used, the stamping die 2 is first installed. During installation, the T-shaped seats 201 on both sides of the stamping die 2 are slid inward along the T-shaped slots 103 on both sides of the die cavity 102, and then the extrusion plug plate 232 is installed. After the stamping die 2 is installed, the pull ring 113 is released. At this time, under the action of the locking spring 112, the plug block 111 and the connecting rod 110 automatically pop out and insert into the positioning groove 234. When the extrusion part 212 is squeezed, the ball thread rod 211 is squeezed and moves vertically downward along the installation cavity 203. Under the clockwise drive of the linkage gear 213, the locking strips 214 on both sides will move outward along the sliding cavity 1 206 and be inserted into the inner locking groove 104. And under the drive of the linkage sleeve 218 and the linkage rod 220, the inner sliding arm 221 will slide outward. Since the first magnetic plate 222 and the second magnetic plate 226 have the same magnetic properties, the repulsive force between the first magnetic plate 222 and the second magnetic plate 226 is greater than the elastic force of the return spring 1 225, so the outer sliding arm 223 will move outward along the sliding cavity 208 and insert into the outer locking groove 105. After the stamping is completed, the cylinder 117 drives the output shaft 118 to move upward. At this time, under the linkage of the first swing arm 122 and the second swing arm 123, the support arm 124 and the roller brush 125 will move upward and clean the bottom of the stamping plate 119. The debris on the stamping plate 119 after cleaning will fall into the stamping cavity 202 below, and the debris will enter the dust suction pump 114 through the upper dust suction channel 230 and the lower dust suction channel 106 in turn.

[0051] When the stamping die 2 needs to be removed, the pull ring 113 is first stretched to both sides. After the insert block 111 is disengaged from the positioning groove 234, the extrusion plug plate 232 is pulled outward through the handle 233. When the extrusion plug plate 232 is removed, the ball screw rod 211 is restored to its original state under the action of the return spring 227. Since the linkage gear 213 and the linkage sleeve 218 are both threadedly connected to the ball screw rod 211, under the counterclockwise drive of the linkage gear 213, the locking strips 214 on both sides will move inward along the sliding cavity 1 206 and disengage from the inner locking groove 104. And under the counterclockwise rotation of the linkage sleeve 218 and the drive of the linkage rod 220, the inner sliding arm 221 will slide inward. Since the first magnetic plate 222 and the second magnetic plate 226 have the same magnetic properties, the repulsive force between the first magnetic plate 222 and the second magnetic plate 226 is smaller than the elastic force of the return spring 1 225 , so the outer sliding arm 223 moves inward along the sliding cavity 208 and disengages from the outer locking groove 105 .
