[0002] A stamping machine generally refers to a stamping press. Stamping production is mainly for processing plate-like materials. Through the mold, various processes such as blanking, punching, and forming can be performed. For example, the hydraulic drive device in the hydraulic stamping mechanism presses down the stamping block, and then the raw materials placed on the placement table are stamped and formed. When the existing stamping mold is in use, it is mostly fixed directly with flanges or bolts. When installing or disassembling the stamping mold, all the bolts need to be repeatedly rotated in sequence, which has high work intensity and reduces the work efficiency of the staff.

[0003] The patent application with publication number CN116921550A discloses an oblique stamping device for parts processing, which specifically relates to the field of stamping equipment, including a press machine, on which an oblique stamping mechanism is arranged, the oblique stamping mechanism includes a positioning die, on which a punching die hole is arranged, a wedge block is arranged on the outside of the positioning die, the wedge block moves laterally, and a punch is fixedly installed on the position of the wedge block corresponding to the punching die hole; a burr pressing structure is arranged inside the press machine, and the burr pressing structure includes a counter-pressure block, and a grinding part is arranged at one end of the counter-pressure block close to the punching die hole. The invention uses the counter-pressure block to drive the grinding part to move and grind the burrs, which not only eliminates the influence of the burrs on the positioning die, but also avoids deformation and stress on the inner wall of the part forming hole, thereby increasing the service life of the equipment and improving the processing accuracy and quality of the parts.

[0017] 1.

When the driving member moves inward, the linkage gears on both sides drive the insertion strip to move to both sides. When the insertion strip is locked into the lower lock hole and squeezes the bottom of the swing plate, the swing plate swings outward at this time. Since the magnetic properties of the inner magnetic plate and the outer magnetic plate are the same, the repulsive force between the inner magnetic plate and the outer magnetic plate is greater than the elastic force of the reset spring 1, so the linkage lock block will move outward along the upper lock hole 1 and be inserted into the upper lock hole 2.

This design is ingenious and effective, which greatly improves the stability and practicality of the stamping workbench with a ejection structure.

[0018] 2. The present invention can quickly unload parts after stamping through the ejection mechanism. When the cylinder moves upward, under the linkage of the bracket and the short swing arm, the lifting plate will move obliquely upward and squeeze the ejector block and the ejector rod. Since the bottom of the ejector rod extends out of the ejector block, the ejector rod will lift the unloading plate upward and tilt it toward the outer unloading slide. And the lifting plate moves obliquely upward, so the heights of the two groups of ejector blocks on the outside are slightly lower than the two groups of ejector blocks on the inside. At this time, the parts are lifted and slide into the unloading slide. This design improves the unloading efficiency of the stamping workbench with an ejection structure.

DETAILED DESCRIPTION

[0034] The following will be combined with the attached Figures 1 to 12The 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.

[0035] The present invention provides a stamping workbench with an ejection structure through improvement. Figure 1-Figure 12 As shown, it includes a stamping device 1, a mold mechanism 2 and an ejection mechanism 3. The stamping device 1 includes a stamping table 101. A mold cavity 102 is provided on the top of the stamping table 101. The mold mechanism 2 can be detachably installed in the mold cavity 102. A cover plate 202 is movably provided on the outer wall of the mold mechanism 2. A stamping cavity 206 is provided on the cover plate 202. Upper lifting holes 205 that cooperate with each other are provided through the cover plate 202 and the mold mechanism 2. A lower lifting hole 104 that cooperates with the upper lifting hole 205 is provided at the bottom of the mold cavity 102. The ejection mechanism 3 includes an ejector block 301, which is movably provided in the upper lifting hole 205 and the lower lifting hole 104. The side of the stamping table 101 A vertical mounting frame 123 is provided, a cylinder 124 is installed on the top of the mounting frame 123, and a punch head 125 is movably installed at the bottom output end of the cylinder 124; a sliding groove 131 is opened on the inner wall of the mounting frame 123, a bracket 126 is fixedly provided on the inner side of the output end of the cylinder 124, and a slide seat 127 slidably set in the sliding groove 131 is fixedly connected to the inner side of the bracket 126, and a long swing arm 128 is movably provided at the bottom of the punching table 101, and a short swing arm 129 is also movably connected to the slide seat 127, and the slide seat 127 is movably connected to the long swing arm 128 through the short swing arm 129, and a lifting plate 130 cooperating with the ejection mechanism 3 is fixedly provided in the middle of the long swing arm 128.

[0036] In this embodiment: the stamping workbench with the ejection structure is mainly divided into three parts: the stamping equipment 1, the mold mechanism 2 and the ejection mechanism 3. When the equipment is used, the mold mechanism 2 is first installed. During installation, the ejection mechanism 3 is first stretched downward to disengage the ejector block 301 from the upper lifting hole 205. Then the arc-shaped portions 201 on both sides of the mold mechanism 2 are slid inward along the arc-shaped seats 103 on both sides of the mold cavity 102, and then the positioning plate 117 is installed. At this time, when the extrusion column 220 is squeezed and the driving member 219 moves inward, the linkage gears 221 on both sides drive the insertion strip 222 to move to both sides. When the insertion strip 222 is inserted into the lower lock hole 107 and squeezes the bottom of the swing plate 110, the swing plate 110 swings outward. Since the repulsive force between the inner magnetic plate 111 and the outer magnetic plate 116 is greater than the elastic force of the return spring 115, the linkage lock block 112 moves outward along the upper lock hole 108 and is inserted into the upper lock hole 231. Since the swing ring 225 is threadedly connected to the screw rod 224, the swing ring 225 is deflected under the drive of the screw rod 224. At this time, under the action of the linkage arm 232, the locking pieces 226 on both sides move inward along the slideway 214 and the vertical track 216 and are inserted into the lower lock cavity 106.

[0037] When the cylinder 124 moves upward, under the linkage of the bracket 126 and the short swing arm 129, the lifting plate 130 moves obliquely upward and squeezes the top block 301 and the top rod 303. Since the bottom of the top rod 303 extends out of the top block 301, the top rod 303 lifts the unloading plate 302 upward and tilts it toward the outer unloading slide 120. And the lifting plate 130 moves obliquely upward, so the heights of the two groups of top blocks 301 on the outer side are slightly lower than the two groups of top blocks 301 on the inner side. At this time, the parts are lifted and slide onto the unloading slide 120 and the conveying mechanism 122.

[0038] See attached Figure 4 -Attached Figure 6 A vertical lifting groove 209 is provided inside the mold mechanism 2, a driving cavity 212 is provided at the bottom of the lifting groove 209, a symmetrical locking groove 218 is provided in the middle of the mold mechanism 2, and symmetrical meshing cavities 210 are provided on both sides of the lifting groove 209; a driving member 219 is slidably provided in the lifting groove 209, a screw rod 224 is fixedly provided at the bottom of the driving member 219, an insertion strip 222 is slidably provided in the locking groove 218, a linkage gear 221 is rotatably provided in the meshing cavity 210, and meshing teeth 223 are provided on both the driving member 219 and the insertion strip 222, and the linkage gear 221 meshes with the driving member 219 and the insertion strip 222 respectively.

[0039] In this embodiment, when the driving member 219 moves inward, the linkage gears 221 on both sides drive the inserting strips 222 to move in both sides. When the inserting strips 222 are inserted into the lower lock hole 107 and press the lower side of the swing plate 110, the swing plate 110 swings outward.

[0040] See attached Figure 4 -Attached Figure 6 A linkage cavity 213 coaxial with the driving cavity 212 is provided in the middle thereof, symmetrical slideways 214 are provided on both sides of the linkage cavity 213, symmetrical insert blocks 215 are provided at the bottom of the mold mechanism 2, the slideways 214 are connected to the insert blocks 215 through vertical channels 216, and a through hole 217 is provided on the inner side of the insert blocks 215; a swing ring 225 meshing with the screw 224 is installed in the linkage cavity 213, the slideways 214, the vertical channels 216 and the insert blocks 215 are connected to each other by the slideways 214, the vertical channels 216 and the insert blocks 215. 5 is slidably provided with a locking member 226; the locking member 226 includes an upper slider 227 slidably provided in the slideway 214 and a lower slider 229 slidably provided in the insert block 215, the upper slider 227 is connected to the lower slider 229 through a connecting plate 228, and the connecting plate 228 is movably provided in the vertical channel 216; a linkage arm 232 is movably installed on the outer wall of the swing ring 225, and the swing ring 225 is movably connected to the upper slider 227 through the linkage arm 232.

[0041] In this embodiment, when the squeezing column 220 is squeezed, the swing ring 225 is threadedly connected to the screw rod 224, so the swing ring 225 is deflected under the drive of the screw rod 224. At this time, under the action of the linkage arm 232, the locking members 226 on both sides move inward along the slideway 214 and the vertical channel 216 and are inserted into the lower lock cavity 106.

[0042] See attached Figure 4 -Attached Figure 5 The top of the driving member 219 is provided with an extrusion column 220, and the top of the lifting groove 209 is provided with an extrusion chamber 211 matched therewith; the bottom of the driving chamber 212 is also provided with a return spring 230, and the bottom of the screw rod 224 abuts against the top thereof.

[0043] In this embodiment: when the extrusion column 220 is squeezed, an extrusion cavity 211 is designed to accommodate it. When the mold mechanism 2 is disassembled and the positioning plate 117 is removed, the screw 224 and the driving member 219 move outward and return to their original positions under the action of the reset spring 230. At this time, when the driving member 219 moves outward, the linkage gears 221 on both sides drive the insertion strip 222 to move inward. When the insertion strip 222 is separated from the lower lock hole 107, under the action of the repulsive magnetic force, the swing plate 110 swings inward and returns to its original position. Since the repulsive force between the inner magnetic plate 111 and the outer magnetic plate 116 is less than the elastic force of the reset spring 115, the linkage lock block 112 will move inward along the upper lock hole 108 and separate from the upper lock hole 231. Since the swing ring 225 is threadedly connected to the screw rod 224 , the locking members 226 on both sides will move outward along the slideway 214 and the vertical channel 216 and disengage from the lower lock cavity 106 under the drive of the screw rod 224 .

[0044] See attached Figure 7 -Attached Figure 8 , arc-shaped portions 201 are provided on both sides of the mold mechanism 2, and arc-shaped seats 103 cooperating with the arc-shaped portions 201 are provided on the inner walls of both sides of the mold cavity 102; a plurality of groups of lower locking holes 107 cooperating with the insert strips 222 are provided on the inner wall of the arc-shaped seat 103, and an upper locking hole 108 arranged in parallel is also provided above the lower locking hole 107, and the lower locking hole 107 is connected with the upper locking hole 108 through a connecting cavity 109; a swing plate 110 is movably installed in the middle of the connecting cavity 109, and an inner magnetic plate 111 is installed on the side of the swing plate 110 facing the upper locking hole 108; a linkage locking block 112 is movably provided in the upper locking hole 108, and an outer magnetic plate 116 cooperating with the inner magnetic plate 111 is provided on the inner side of the linkage locking block 112, and the inner magnetic plate 111 and the outer magnetic plate 116 have the same magnetic properties.

[0045] In this embodiment: when the outer positioning plate 117 is installed, the screw 224 and the driving member 219 move inward under the extrusion. At this time, when the driving member 219 moves inward, the linkage gears 221 on both sides drive the insertion strip 222 to move to both sides. When the insertion strip 222 is inserted into the lower lock hole 107 and squeezes the bottom of the swing plate 110, the swing plate 110 swings outward at this time. Since the repulsive force between the inner magnetic plate 111 and the outer magnetic plate 116 is greater than the elastic force of the reset spring 115, the linkage lock block 112 will move outward along the upper lock hole 108 and be inserted into the upper lock hole 231.

[0046] See attached Figure 7 -Attached Figure 8, upper locking holes 231 cooperating with the linkage locking block 112 are also provided on both sides of the mold mechanism 2; symmetrical sliding grooves 113 are provided on the upper and lower inner walls of the upper locking hole 108, and vertical plates 114 are provided on the upper and lower inner walls of the linkage locking block 112, and multiple groups of return springs 115 are connected to the outer side of the vertical plates 114, and the vertical plates 114 are connected to the inner wall of the sliding groove 113 through the return springs 115.

[0047] In this embodiment: when the swing plate 110 swings, in order to automatically drive the interlocking lock block 112 to lock and unlock the upper lock hole 231 through the repulsive force between the inner magnetic plate 111 and the outer magnetic plate 116, the interlocking lock block 112 is connected to the inner wall of the slide groove 113 through the reset spring 115.

[0048] See attached Figure 2 and attached Figure 7 A lower plug hole 105 cooperating with the inner plug block 215 is provided on the bottom inner wall of the mold cavity 102 , and a lower locking cavity 106 cooperating with the lower slider 229 is provided on the inner side of the lower plug hole 105 .

[0049] In this embodiment, in order to fix the mold mechanism 2 into the mold cavity 102 , a lower locking cavity 106 is opened at the bottom of the mold cavity 102 .

[0050] See attached Figure 4 and attached Fig. 9 A positioning plate 117 cooperating with the mold mechanism 2 is movably installed on the outer side of the mold cavity 102, a symmetrical external plug-in block 118 is arranged on the inner side of the positioning plate 117, and a positioning hole 208 cooperating with the external plug-in block 118 is opened on the top of the mold mechanism 2; a handle 119 is arranged on the outer side of the positioning plate 117, an inclined unloading slide 120 is fixedly arranged on the top of the positioning plate 117, a conveying mechanism 122 is arranged on the outer side of the stamping table 101, and a plurality of groups of bolts 121 are screwed to the positioning plate 117.

[0051] In this embodiment, when the mold mechanism 2 is installed in the mold cavity 102, a positioning plate 117 is designed to position and automatically lock it. When the stamped parts are lifted, a material unloading slide 120 is designed to transport them to the conveying mechanism 122.

[0052] See attached Fig.10 -Attached Fig.12 A blanking plate 302 is movably installed on the top of the top block 301, and a top rod 303 is movably arranged inside the top block 301. A symmetrical limiting arm 304 is arranged on the top of the top rod 303, and the bottom of the top rod 303 extends out of the bottom of the top block 301; multiple groups of bosses 305 are arranged on the outer wall of the top block 301, and multiple groups of return springs 306 are connected to the bosses 305. The ejection mechanism 3 is connected to the bottom of the stamping table 101 through the return springs 306.

[0053] In this embodiment: when the cylinder 124 moves upward, under the linkage of the bracket 126 and the short swing arm 129, the lifting plate 130 will move obliquely upward and squeeze the top block 301 and the top rod 303. Since the bottom of the top rod 303 extends out of the top block 301, the top rod 303 will lift the unloading plate 302 upward and tilt it toward the outer unloading slide 120. And the lifting plate 130 moves obliquely upward, so the heights of the two groups of top blocks 301 on the outer side are slightly lower than the two groups of top blocks 301 on the inner side. At this time, the parts are lifted and slide into the unloading slide 120. When the cylinder 124 moves downward, the lifting plate 130 will move obliquely downward and separate from the top block 301 and the top rod 303. At this time, the ejection mechanism 3 returns to its original position under the action of the return spring 306.

[0054] See attached Figure 3 A T-shaped slot 203 is provided on the side of the mold mechanism 2, a T-shaped rail 204 matching with the cover plate 202 is provided at the bottom, and a plurality of reinforcing ribs 207 are provided on the outer wall of the stamping cavity 206.

[0055] In this embodiment, in order to further facilitate the replacement of stamping cavities 206 of different specifications, a detachable cover plate 202 structure is designed. In order to further improve the stability and strength of the stamping cavity 206 and avoid deformation after long-term use, a reinforcing rib 207 structure is designed.

[0056] Working principle of the present invention: When the device is used, the mold mechanism 2 is first installed. During installation, the ejection mechanism 3 is first stretched downward to disengage the ejector block 301 from the upper lifting hole 205. Then the arc-shaped portions 201 on both sides of the mold mechanism 2 are slid inward along the arc-shaped seats 103 on both sides of the mold cavity 102, and then the positioning plate 117 is installed. At this time, when the extrusion column 220 is squeezed and the driving member 219 moves inward, the linkage gears 221 on both sides drive the insertion strip 222 to move to both sides. When the insertion strip 222 is inserted into the lower lock hole 107 and squeezes the bottom of the swing plate 110, the swing plate 110 swings outward at this time. Since the repulsive force between the inner magnetic plate 111 and the outer magnetic plate 116 is greater than the elastic force of the reset spring 115, the linkage lock block 112 will move outward along the upper lock hole 108 and be inserted into the upper lock hole 231. Since the swing ring 225 is threadedly connected to the screw rod 224, the swing ring 225 deflects under the drive of the screw rod 224. At this time, under the action of the linkage arm 232, the locking members 226 on both sides move inward along the slideway 214 and the vertical channel 216 and are inserted into the lower lock cavity 106.

[0057] When the cylinder 124 moves upward, under the linkage of the bracket 126 and the short swing arm 129, the lifting plate 130 moves obliquely upward and squeezes the top block 301 and the top rod 303. Since the bottom of the top rod 303 extends out of the top block 301, the top rod 303 lifts the unloading plate 302 upward and tilts it toward the outer unloading slide 120. And the lifting plate 130 moves obliquely upward, so the heights of the two groups of top blocks 301 on the outer side are slightly lower than the two groups of top blocks 301 on the inner side. At this time, the parts are lifted and slide onto the unloading slide 120 and the conveying mechanism 122.
