Description

Technical Field

[0001] This invention belongs to the field of metal stamping technology, and in particular relates to an automatic continuous stamping machine for small metal parts. Background Technology

[0002] Small metal stamping parts are small metal components manufactured using stamping technology. They are typically made of metal materials such as stainless steel, aluminum alloy, and steel sheet, and possess good corrosion resistance, wear resistance, and high-temperature resistance. They are commonly used in the manufacture of various small mechanical devices and components, such as computers, mobile phones, automobiles, electronic products, home appliances, and furniture.

[0003] Small hardware parts are all made by stamping machines. The existing stamping technology is relatively mature and can automatically and continuously stamp small hardware parts. However, after stamping, the small hardware parts will pile up together, which may lead to scratches and bumps on the small hardware parts, thereby reducing the production quality of the small hardware parts and affecting their precision. Summary of the Invention

[0004] In order to overcome the shortcomings of existing stamping methods that easily lead to the accumulation of metal parts, resulting in a decline in quality and precision, the purpose of this invention is to provide an automatic continuous stamping machine for small metal parts that can automatically arrange and organize them with high quality.

[0005] The technical implementation of this invention is as follows: An automatic continuous stamping machine for small hardware parts includes a stamping machine, a fixed frame, and a transport frame. A stamping head is mounted on the stamping machine. The fixed frame is connected to the left side of the stamping machine, and several transport frames are provided on the fixed frame. The machine also includes a push rod, a return spring, an extrusion plate, an extrusion rod, a lifting frame, a rotating plate, a fixed plate, a rotating plate, a fixed rod, and a push assembly. A stamping groove is formed at the bottom of the stamping machine, and a push rod is slidably connected to the bottom of the stamping machine to push out small hardware parts from the stamping groove. The rod slides in the stamping groove. A return spring connects the push rod to the stamping machine. Two extrusion plates and two extrusion rods are connected to the upper part of the stamping head. A lifting frame is slidably connected to the lower part of the stamping machine. Rotating plates are rotatably connected to both sides of the stamping machine. Fixed plates are connected to the front and rear of the right side of the fixed frame. Several rotating plates supporting small hardware parts are rotatably connected to the two fixed plates close to each other. Fixed rods equal in number to the rotating plates are also connected to the two fixed plates close to each other. Pushing components are provided on the fixed plates.

[0006] In one embodiment, the pushing assembly includes a cylinder, a sliding rod, a pushing frame, a tension spring, and a connecting plate. A cylinder is mounted on the upper part of one of the fixed plates. A sliding rod is connected to the telescopic rod of the cylinder. A pushing frame that pushes out small hardware parts on the rotating plate is slidably connected to the right side of the sliding rod. A tension spring is connected between the pushing frame and the sliding rod. A connecting plate is connected between the two fixed plates.

[0007] In one embodiment, a pulley assembly is also included, with the pulley assembly mounted on the upper part of the fixed frame, and the transport frames all in contact with the pulley assembly.

[0008] In one embodiment, the system further includes a sliding frame, a helical spring, a compression spring, and a limiting block. The upper part of the fixed frame is slidably connected to the sliding frame for limiting the transport frame. A helical spring is connected between the sliding frame and the fixed frame. The front part of the sliding frame is slidably connected to the limiting block, and a compression spring is connected between the limiting block and the sliding frame.

[0009] In one embodiment, it also includes an air supply pipe, a blower, and an air blowing pipe. A blower is mounted on the upper part of another fixed plate, and an air supply pipe is connected to the blower. Several air blowing pipes are connected to the air supply pipe.

[0010] In one embodiment, the rotating plate shafts are all located on the side closest to the adjacent fixed plate.

[0011] In one embodiment, the upper part of the lifting frame is U-shaped.

[0012] In one embodiment, each rotating plate has a sliding groove, and the lifting frame moves within the sliding groove.

[0013] In one embodiment, both the compression rod and the sliding rod are L-shaped.

[0014] In one embodiment, one side of the limiting block is arc-shaped.

[0015] Beneficial effects: 1. This invention uses a pusher rod to push the stamped small hardware parts onto a rotating plate. The lifting frame then pushes the small hardware parts on the rotating plate one by one upwards, so that the rotating plate is full of small hardware parts. The rotating plate separates all the small hardware parts, thereby avoiding scratches on the small hardware parts and improving the production quality of the small hardware parts. Then, by controlling the cylinder, the pusher frame pushes the small hardware parts on the rotating plate onto the transport frame, thereby ensuring continuous stamping of small hardware parts.

[0016] 2. This invention controls the pulley assembly to transport small hardware parts in a transport frame without manual movement, reducing labor intensity and workload; the sliding frame and limiting block limit the transport frame to prevent multiple transport frames from accumulating inside the sliding frame, thus ensuring the normal transport of small hardware parts; and the blower controls the blower to blow air onto the small hardware parts, thus preventing debris from remaining on the small hardware parts.

Detailed Implementation

[0031] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0032] Example 1: An automatic continuous stamping machine for small hardware parts, reference Figures 1-13 The assembly includes a stamping machine 1, a fixed frame 2, a transport frame 21, a pusher rod 3, a return spring 4, an extrusion plate 5, an extrusion rod 6, a lifting frame 7, a rotating plate 8, a fixed plate 9, a rotating plate 10, a fixed rod 11, and a pusher assembly. A stamping head 101 is mounted on the stamping machine 1. A stamping groove 31 is opened at the bottom of the stamping machine 1. A fixed frame 2 is fixedly connected to the left side of the stamping machine 1. Several transport frames 21 are provided on the fixed frame 2. A pusher assembly is slidably connected to the bottom of the stamping machine 1. The push rod 3 slides within the stamping groove 31. A return spring 4 connects the push rod 3 to the stamping machine 1. Two extrusion plates 5 are fixedly connected to the upper right side of the stamping machine 1. The downward movement of the extrusion plates 5 will extrude the push rod 3. Two extrusion rods 6 are fixedly connected to the upper left side of the stamping machine 1. The extrusion rods 6 are L-shaped. A lifting frame 7 is slidably connected to the lower part of the stamping machine 1. A rotating plate 8 is rotatably connected to the lower part of the stamping machine 1, both front and rear. The left side of the rotating plate 8 is open. There is a slide groove 81, and the lifting frame 7 moves within the slide groove 81. When the pressing rod 6 moves downward, it will press the adjacent rotating plate 8. When the rotating plate 8 rotates, it will press the lifting frame 7. The upper part of the lifting frame 7 is U-shaped, so that the upper part of the lifting frame 7 is fully in contact with the lower part of the small hardware. When the lifting frame 7 moves upward, it will press the stamped small hardware. The right side of the fixed frame 2 is fixed with fixed plates 9 at the front and back. On the side of the two fixed plates 9 that are close to each other, several rotating plates 10 are rotatably connected. The rotating plates 10 are all on the side close to the adjacent fixed plates 9. So when the rotating plates 10 rotate upward and separate from the small hardware, they will rotate downward and reset under the gravity of the side of the rotating plates 10 away from the fixed plates 9. On the side of the two fixed plates 9 that are close to each other, there are also fixed rods 11 in the same number as the rotating plates 10. When the rotating plates 10 rotate downward, they will be pressed by the fixed rods 11. The fixed plates 9 are equipped with a pusher assembly.

[0033] refer to Figures 1-11 The pushing assembly includes a cylinder 121, a sliding rod 122, a pushing frame 123, a tension spring 124, and a connecting plate 125. The cylinder 121 is bolted to the upper part of the front fixed plate 9. The sliding rod 122 is fixed to the telescopic rod of the cylinder 121. The sliding rod 122 is L-shaped. The pushing frame 123 is slidably connected to the right side of the sliding rod 122. The tension spring 124 is fixed between the pushing frame 123 and the sliding rod 122. When the pushing frame 123 moves to the left, it will squeeze the small hardware parts stamped on the rotating plate 10. The connecting plate 125 is fixed between the left sides of the two fixed plates 9. When the pushing frame 123 moves to the left, it will contact the connecting plate 125.

[0034] First, the small hardware part material is fed directly above the stamping groove 31. Then, the stamping head 101 is controlled to move downwards to stamp the small hardware part material. The downward movement of the stamping head 101 will drive the extrusion plate 5 to move downwards as well. The downward movement of the extrusion plate 5 will squeeze the push rod 3, causing the push rod 3 to move to the right within the stamping groove 31. The return spring 4 is stretched. After the stamping head 101 has finished stamping the small hardware part material, the small hardware part will be placed in the stamping groove 31. The stamping machine 1 is then controlled to move the stamping head 101 upwards to return to its original position. When the stamping head 101 moves upward, it will drive the extrusion plate 5 to move upward as well. When the extrusion plate 5 moves upward together, it will separate from the push rod 3, and the return spring 4 will return to its original state. This will cause the push rod 3 to move to the left in the stamping groove 31. The push rod 3 will then squeeze the small hardware parts in the stamping groove 31, causing the small hardware parts to move to the left together. When the small hardware parts move to the left, they will slide onto the rotating plate 10 under the different fixed plates 9. At this time, the small hardware parts squeeze the rotating plate 10, and the fixed rod 11 also squeezes the rotating plate 10, thereby limiting the rotation plate 10.

[0035] As the stamping head 101 moves downwards, it also drives the extrusion rod 6 downwards. Since the extrusion rod 6 is L-shaped, its downward movement compresses the rotating plate 8, causing it to rotate. This rotation compresses the lifting frame 7, causing its lower part to move within the slide groove 81, and consequently, the lifting frame 7 to move upwards. Because the upper part of the lifting frame 7 is U-shaped, its upward movement compresses the small hardware component below the fixed plate 9, causing it to move upwards. This upward movement compresses the upper rotating plate 10, causing it to rotate upwards. As the small hardware component continues to move upwards, it separates from the upper rotating plate 10, at which point it is positioned above the upper rotating plate 10. Since the rotating shafts of the rotating plates 10 are all located on the side closest to the adjacent fixed plates 9, after the upper rotating plate 10 rotates upward and separates from the small hardware parts, under the gravity of the side of the rotating plate 10 away from the fixed plate 9, the upper rotating plate 10 will rotate downward to reset, thereby supporting the small hardware parts on the upper rotating plate 10. This causes the small hardware parts below to be continuously lifted upward, making it easier to push subsequent small hardware parts onto the rotating plate 10 below the fixed plate 9. By placing the small hardware parts on different rotating plates 10, the small hardware parts are prevented from piling up, thus avoiding scratches and bumps, improving the production quality of the small hardware parts, and ensuring their precision.

[0036] After small hardware parts are placed on the rotating plate 10 on the fixed plate 9, the cylinder 121 is controlled so that the telescopic rod of the cylinder 121 drives the sliding rod 122 to slide to the left. Since the sliding rod 122 is L-shaped, the sliding rod 122 will compress the tension spring 124 when it slides to the left. The tension spring 124 will then compress the pusher 123, causing the pusher 123 to move to the left as well. The pusher 123 will compress the small hardware parts on the rotating plate 10 when it moves to the left and contacts the connecting plate 125. 23 can push all the small hardware parts on the rotating plate 10 into the transport frame 21 on the left, thereby collecting the small hardware parts on the rotating plate 10, so that the stamping machine 1 can continuously stamp, thereby ensuring the stamping efficiency of the small hardware parts. After the small hardware parts are pushed into the transport frame 21, the cylinder 121 is controlled to make the telescopic rod of the cylinder 121 slide to the right, thereby making the sliding rod 122 move to the right to reset. The movement of the sliding rod 122 to the right will drive the pusher 123 to move to the right to reset through the action of the tension spring 124.

[0037] Example 2: Based on Example 1, refer to Figures 1-11It also includes a pulley assembly 131, which is installed on the upper part of the fixed frame 2, and the transport frames 21 are all in contact with the pulley assembly 131. By controlling the pulley assembly 131, the transport frames 21 can be automatically transported after collection, thus eliminating the need for manual movement, reducing labor intensity and workload.

[0038] refer to Figure 1 , Figure 11 and Figure 12 It also includes a sliding frame 141, a helical spring 142, a compression spring 143, and a limiting block 144. The sliding frame 141 is slidably connected to the upper part of the fixed frame 2. The sliding frame 141 is in contact with the transport frame 21 at both the front and rear. The helical spring 142 is fixed between the sliding frame 141 and the fixed frame 2. The limiting block 144 is slidably connected to the front of the sliding frame 141. The right side of the limiting block 144 is arc-shaped. The compression spring 143 is fixed between the limiting block 144 and the sliding frame 141. When the sliding rod 122 moves to the left, it will squeeze the sliding frame 141.

[0039] When the pusher 123 contacts the connecting plate 125, the cylinder 121 is controlled to continue moving its extension rod to the left, causing the sliding rod 122 to continue sliding to the left. Since the pusher 123 is in contact with the connecting plate 125, it cannot continue moving to the left. At this point, the tension spring 124 is stretched, and the sliding rod 122, continuing to slide to the left, will compress the sliding frame 141, causing it to move to the left. The helical spring 142 is stretched, and the sliding... When the sliding frame 141 moves to the left, it no longer limits the transport frame 21 filled with small hardware parts. Under the action of the pulley assembly 131, the transport frame 21 filled with small hardware parts moves backward for transport. Simultaneously, as the sliding frame 141 moves to the left, the empty transport frame 21 in front of the sliding frame 141 moves backward under the action of the pulley assembly 131. Once the transport frame 21 filled with small hardware parts separates from the sliding frame 141, the cylinder 121 is controlled to extend or retract. The lever drives the sliding rod 122 to move to the right, the tension spring 124 returns to its original position, and the sliding rod 122 no longer compresses the sliding frame 141. The coil spring 142 returns to its original position, causing the sliding frame 141 to move to the right and return to its original position. Since there is a gap between the two transport frames 21, when the transport frame 21 filled with small hardware parts separates from the sliding frame 141, the empty transport frame 21 has not yet fully entered the sliding frame 141. At this time, the empty transport frame 21 will compress the limiting block 144, thus limiting the movement. When block 144 moves to the left, compression spring 143 is compressed. Since the right side of limit block 144 is arc-shaped, empty transport frame 21 will continue to move backward into sliding frame 141. At this time, compression spring 143 returns to its original state, limit block 144 moves to the right, and limit block 144 can then limit subsequent empty transport frames 21, so that there is no need to stop pulley assembly 131, and multiple transport frames 21 will not accumulate in sliding frame 141, thus ensuring the normal transport of small hardware parts.

[0040] refer to Figure 1 and Figure 13 It also includes an air supply pipe 151, a blower 152 and an air blowing pipe 153. The blower 152 is installed on the upper part of the fixed plate 9 on the rear side. The air supply pipe 151 is fixedly connected to the blower 152. Several air blowing pipes 153 are fixedly connected to the lower part of the air supply pipe 151.

[0041] The blower 152 is controlled so that air enters the blowing pipe 153 through the air supply pipe 151 and is then blown out, thereby removing the debris generated during the stamping process of small hardware parts and preventing debris from remaining on the small hardware parts.

[0042] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of the invention.
