They refer to various parts and accessories made of metal materials and are widely used in various fields such as electrical and mechanical. The processing of mechanical parts benefits from stamping technology. The stamping device is used to align the upper and lower molds, and the metal sheet placed between the upper and lower molds is punched or deformed to make it conform to the shape of the mold slot, forming the required shape of the mechanical parts. During the use of the existing stamping devices on the market, for some mechanical parts that need to be stamped, deformed and bent, a compression elastic mechanism is usually set in the lower die during the stamping and bending process.

[0018] In this embodiment: mechanical parts refer to various parts and accessories made of metal materials, which are widely used in various fields such as construction, machinery, furniture, and electrical appliances. The processing of mechanical parts benefits from stamping technology. The upper and lower molds are matched by a stamping device, and the metal sheet placed between the upper and lower molds is punched or deformed to conform to the shape of the mold slot, forming the required shape of the mechanical parts; During the use of the existing stamping dies on the market, for some mechanical parts that need to be stamped, deformed and bent, a compression elastic mechanism is usually set in the lower die during the stamping and bending process. After the stamping is completed, when the stamping machine moves up and resets the upper die quickly, the elastic mechanism instantly rebounds to push the stamped mechanical parts out of the lower die to complete a single stamping. However, sometimes due to problems such as uneven thickness of the material to be stamped and dirt on the surface, the elastic mechanism cannot smoothly eject the mechanical parts out of the lower die when it rebounds, resulting in a stagnation in the production process, which requires manual unblocking. In order to avoid the above situation, when using the stamping die, firstly, one end of the processed steel plate 3 to be stamped is inserted between the two conveying wheels 6, and the processed steel plate 3 is placed between the two limiting rings 7 to prevent the processed steel plate 3 from escaping, and one end of the processed steel plate 3 is inserted into the inner wall of the fourth slide groove 103, and the end of the first groove 18 is placed directly below the first guide rod 20. At this time, the punch 10 is started, and the punch 10 moves downward with the mounting plate 11 at the output end and the upper die 12 as a whole. When the fixing plate 16 moves downward and contacts the lower die 8, When the upper die 12 is formed, the first guide rod 20 is pressed against the surface of the workpiece 3. At this time, the first guide rod 20 continues to move downward. Since the fixed plate 16 cannot move downward, the fixed plate 16 will squeeze the guide column 15 to compress the first spring 14, thereby forcing the guide column 15 to slide into the guide groove 17 of the outer wall of the upper die 12. At this time, the distance between the fixed plate 16 and the upper die 12 is reduced, causing the first guide rod 20 to gradually pass through the guide groove 17 and quickly punch to the corresponding position of the workpiece steel plate 3. After piercing the corresponding position of the workpiece steel plate 3, the first guide rod 20 enters the through hole 101 with the pierced part, and the pierced waste falls through the through hole 101. Then, the transmission motor 5 is started, and the transmission motor 5 drives the conveying wheel 6 at the output end to rotate. The conveying wheel 6 starts to move with the processed steel plate 3 on the outer wall, and at this time, the other side of the processed steel plate 3 contacts the other conveying wheel 6. The friction force causes the other conveying wheel 6 to rotate, which can reduce the friction resistance of the processed steel plate 3 during transportation and movement. At this time, the processed steel plate 3 is transported in the direction close to the feed frame 4, and each time the transmission motor 5 is started, it will rotate the same number of circles, so that the distance moved by the processed steel plate 3 is the same each time; During the conveying process, the processed steel plate 3 will slide through the fourth slide groove 103. When the processed steel plate 3 continues to move, the position just pierced by the first guide rod 20 will move to the vicinity of the second groove 26. At this time, the punch 10 is started. When the mounting plate 11 and the upper mold 12 move downward, the above operation will be repeated. At this time, due to the gradual reduction in the distance between the upper mold 12 and the fixed plate 16, the first protrusion 19 is gradually protruded outward along the first groove 18, and the corresponding part of the processed steel plate 3 is pressed into the second groove 26, causing the processed steel plate 3 to deform into the second groove 26. When the processed steel plate 3 is deformed into the second groove 26, both sides will be pulled into the second groove 26. At this time, since the processed steel plate 3 is on the inner wall of the fourth slide groove 103, the fixed plate 16 will not hinder the processed steel plate 3. The two sides are pulled and deformed toward the second groove 26. Since the contour of the first protrusion 19 matches the inner contour of the second groove 26, when the first protrusion 19 presses the processed steel plate 3 to bend and deform and enter the second groove 26, the second groove 26 will gradually be squeezed by the outer wall of the first protrusion 19 and the inner wall of the second groove 26, and finally form the shape of the inner contour of the second groove 26. After the first protrusion 19 gradually presses the processed steel plate 3 to enter the second groove 26 for a distance, the cutting tool 25 on the outer wall of the first protrusion 19 will contact the position of the processed steel plate 3 on the surface of the lower mold 8, and cut the processed steel plate 3 as it moves downward. After the first protrusion 19 completely enters the second groove 26, the cutting tool 25 will be in the third groove 102, and the stamping of the mechanical parts is completed. During the downward movement of the fixed plate 16, before it hits the surface of the lower mold 8, the fixed plate 16 will first hit the push rod 392, and the push rod 392 will be forced downward with the extension rod 391 and the third guide rod 30, so that the third guide rod 30 and the second abutment block 32 at the end thereof will slide along the surface of the third inclined surface 35. Since the first slider 29 slides in the second slide groove 28, it is restricted by the second slide groove 28 and cannot move up and down. Therefore, the third guide rod 30 is gradually moved downward along the inner wall of the first slider 29, and the first slider 29 begins to slide obliquely downward along the inclined inner wall of the second slide groove 28. The third guide rod 30 moves and moves downward, so that the moving frame 39 moves and moves downward with it, until the fixed plate 16 hits the surface of the lower mold 8, and the position of the moving frame 39 will move to the bottom of the processed steel plate 3. As the first protrusion 19 presses the processed steel plate 3 into the second groove 26, as the processed steel plate 3 moves downward along the inner wall of the second groove 26, it will contact the moving frame 39 to cause it to slide downward along the prism 37, causing the end of the prism 37 to slide into the moving frame 39, and finally contact the engaging block 41, causing the engaging block 41 to compress the fifth spring 42 and move upward along the fifth slide groove 40. When the engaging block 41 has not yet moved to the end of the fifth slide groove 40, the engaging block 41 has already contacted the outer wall of the processed steel plate 3, as shown in the attached figure. Fig.12 As shown in , at this time, the locking block 41 cannot move further. When the processed steel plate 3 continues to deform into the second groove 26 and press the moving frame 39 downward, the first slider 29 will continuously compress the seventh spring 291 and slide along the inclined second slide groove 28. When the position of the locking block 41 is out of contact with the lower surface of the processed steel plate 3, the processed steel plate 3 is continued to be pressed against the moving frame 39, which will cause the prism 37 to compress the fourth spring 38 and further enter the moving frame 39, causing the locking block 41 to be resisted and continue to move upward, causing the locking block 41 to stick to the side wall of the processed steel plate 3 that has been formed, as shown in the attached figure. Fig.12 As shown in the figure, when the processed steel plate 3 is stamped, the punch 10 moves up quickly with the upper mold 12 as a whole, and the seventh spring 291 quickly brings the first slider 29 to rebound and slide back in the second slide groove 28. At this time, the mechanical parts that are cut off and separated after the stamping are pressed against the moving frame 39, and the weight is much greater than the sum of the elastic forces of the fourth spring 38 and the fifth spring 42. It should be noted that the elastic force of the seventh spring 291 is relatively large. At this time, while the moving frame 39 follows the first slider 29 to slide back, the engaging block 41 will press against the side wall of the formed processed steel plate 3 and move quickly toward the direction of the first storage box 2, and the moving frame 39 is also constantly moving synchronously at this time. In the process of moving, since the first slider 29 will continuously slide along the inclined second slide groove 28, The sliding movement is performed upward, and because the second inclined surface 33 on the second abutting block 32 abuts against the third inclined surface 35, the third guide rod 30 and the moving frame 39 are continuously lifted, and the mechanical parts are synchronously lifted and moved toward the first storage box 2. When the first slide block 29 slides to the end of the second slide groove 28, the sliding movement is suddenly stopped, and the mechanical parts are separated from the upper surface of the moving frame 39 due to inertia, and fall into the first storage box 2 for collection, so that the direction in which the mechanical parts are ejected during demoulding can be controlled, and the problem of random ejection and possible stay on the table in the prior art can be avoided. At this time, there is no pressure, and the fourth spring 38 rebounds and moves the moving frame 39 upward along the outer wall of the prism 37. At this time, the engaging block 41 has no upward abutment force of the prism 37, and the fifth spring 42 rebounds and resets the engaging block 41. In the above process, the bottom of the formed processed steel plate 3 is supported by the upper surface of the moving frame 39 and continuously moves toward the first storage box 2. Therefore, the processed steel plate 3 has a tendency to fall toward the direction close to the locking block 41 by inertia. However, since the locking block 41 is in the state of being moved upward at this time, the attached Fig.12 The state in the middle can prevent the formed processed steel plate 3 from falling backwards due to inertia when moving, and the reset of the seventh spring 291 will bring the first slider 29 to slide along the second slide groove 28. Since the first slider 29 is restricted in the guide track of the inner wall of the second slide groove 28, it cannot shake in the left and right directions except for moving forward and backward, and when the third guide rod 30 and the second contact block 32 at the end slide along the third inclined surface 35, since the first slider 29 is restricted in the second slide groove 28, it cannot shake in other directions. Therefore, in the whole process of throwing the formed processed steel plate 3 into the first storage box 2, the weight of the formed processed steel plate 3 is greater than the sum of the elastic forces of the fifth spring 42 and the fourth spring 38, and the elastic forces of the fifth spring 42 and the fourth spring 38 cannot affect the moving processed steel plate 3, and the formed processed steel plate 3 moving toward the first storage box 2 for unloading is always in the second groove 26 When the formed processed steel plate 3 is moved, the two sides of the inner wall of the second groove 26 can also effectively prevent the formed processed steel plate 3 from falling to the two sides. When the formed processed steel plate 3 is dragged and resisted by the moving frame 39 and the locking block 41 to be exposed outside the notch of the second groove 26, the reset limit of the seventh spring 291 is reached at this time. At this time, the moving frame 39 of the formed processed steel plate 3 will suddenly stop moving, and it will fly out due to inertia, fly out in the direction of the first storage box 2, and at this time, it is close to the notch of the first storage box 2. It should be noted that the stamping process is relatively fast. Although the formed processed steel plate 3 is also ejected at the same time as the punch 10 moves up with the mounting plate 11 and the fixing plate 16, the speed of the punch 10 moving up with the output end is faster. The order is that the output end of the punch 10 moves up quickly after stamping, and the speed is greater than the rebound speed of the seventh spring 291. Therefore, the ejected processed steel plate 3 will not be easy to contact the lower surface of the fixing plate 16; And in the process of the fixed plate 16 moving downward, it will move downward with the first resistance block 21, and the first resistance block 21 will resist the fourth resistance block 45 during the downward movement, so that the first inclined surface 23 and the fourth inclined surface 46 will resist each other, so that the fourth resistance block 45 will carry the push plate 44 to move in the direction away from the sixth spring 43. At this time, the sixth spring 43 is pulled up, and when the fixed plate 16 resists the surface of the lower mold 8, the sixth spring 43 stops stretching. When the stamping is completed, the upward movement of the upper mold 12 will first move the first protrusion 19 upward, and then the first spring 14 rebounds and carries the guide column 15 to gradually slide out of the guide groove 17. Under normal demoulding conditions, at this time The moving frame 39 and the locking block 41 have moved the mechanical parts up a distance along the second groove 26. Finally, when the fixed plate 16 moves up and begins to move up, the resistance to the fourth inclined surface 46 will be released. At this time, the sixth spring 43 rebounds and carries the push plate 44 to slide quickly into the second groove 26. If the demolding is abnormal, the part of the mechanical parts that remain at the bottom of the second groove 26 will be impacted by the rapidly moving push plate 44, and will be knocked onto the fifth inclined surface 48 in the direction close to the through groove 47, and finally slide into the second storage box 201. At this time, it indicates that the thickness of this batch of stamping materials is uneven or sticky and dirty, which is convenient for the staff to distinguish.

[0019] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0020] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
