Description

Technical Field

[0001] This invention relates to the field of stamping, and more particularly to an automated stamping equipment for metal materials. Background Technology

[0002] In existing metal can bottom stamping technology, after the stamping head stamps multiple metal can bottoms sequentially on the metal sheet, a special guiding mechanism is usually needed to guide the stamped can bottoms to a collection mechanism. The collection mechanism then neatly stacks the can bottoms one by one. This split-structure design means that in addition to the stamping machine, the entire stamping equipment must also have additional guiding and collection mechanisms arranged along the production line, which significantly extends the overall length of the equipment. At the same time, to meet the accuracy requirements of guiding and stacking, sufficient transition and maintenance space must be reserved between each mechanism, further increasing the horizontal and vertical footprint of the equipment. In addition, some existing solutions use multiple stamping machines with independent collection devices to complete the forming and collection of can bottoms. The equipment is scattered and the mechanisms are large, which not only occupies a large area but also has the problems of high energy consumption and relatively low efficiency. These drawbacks are particularly prominent in the case of limited workshop space. They not only compress the layout space of other auxiliary equipment but also increase the difficulty of production line planning and infrastructure costs, which is not conducive to achieving a compact and intensive automated production layout. Summary of the Invention

[0003] In order to overcome the shortcomings of existing metal material tank bottom stamping technology, which requires additional guiding and collecting mechanisms along the production line and whose split structure design results in large equipment footprint and low processing efficiency, this invention provides an automated metal material stamping equipment.

[0005] Preferably, a limiting ring plate is fixedly attached to the mounting frame, and the limiting ring plate is in close contact with the upper surface of the mold base.

[0006] Preferably, an electric heating coil is installed on the limiting ring plate.

[0007] In another embodiment, preferably, the support shaft has an air supply channel structure; the support shaft has several air outlet structures that connect to the air supply channel; the mold base has several first air jet holes that connect to the corresponding air outlet holes, and the first air jet holes pass through the upper and lower stamping mold grooves respectively; an air supply valve is fixedly connected to the electric lifting frame; the air supply valve is rotatably connected to the support shaft, and the air supply port of the air supply valve connects to the air supply channel of the support shaft.

[0013] Preferably, a buffer block is fixed to the surface of the pallet.

[0014] The beneficial effects of this invention: The automated metal stamping equipment of this invention features a die base with upper and lower stamping die grooves. A stamping head, in conjunction with the upper stamping die groove of the die base, stamps the bottom of a metal can onto a metal sheet. An electric lifting frame, in conjunction with a tilting motor, rotates the die base, causing the metal can bottom to be flipped to the lower area of ​​the die base. Then, the stamping head again, in conjunction with the upper stamping die groove of the die base, stamps the next metal can bottom onto the metal sheet. Simultaneously, the metal can bottoms in the lower stamping die groove of the die base fall downwards into a collection bin for stacking and collection, eliminating the need for additional guiding and conveying mechanisms. The mechanism eliminates the transition space required for long-distance conveying of the tank bottom, significantly reduces the overall footprint of the equipment, significantly shortens the process interval time, and improves the output efficiency per unit time. It achieves integrated processes of stamping, flipping, demolding, and stacking with extremely simple mechanical movements, taking into account the simultaneous optimization of space utilization, operational reliability, and production cycle. It solves the technical problems of existing metal material tank bottom stamping processing technology, which requires additional guide and collection mechanisms along the production line direction, and the split structure design that leads to large equipment footprint and low processing efficiency.

[0018] Example 1: An automated metal stamping equipment according to this example, such as... Figures 1-5 As shown, the assembly includes a mounting frame 1, a stamping main unit 2, a stamping head 21, an electric lifting frame 3, a support shaft 31, a die base 32, a tilting motor 33, an air supply valve 34, and a collection tank 5. The stamping main unit 2 is mounted on the mounting frame 1. The stamping head 21 is mounted on the stamping main unit 2. The electric lifting frame 3 is slidably connected to the mounting frame 1. The support shaft 31 is rotatably connected inside the electric lifting frame 3. The die base 32 is fixedly connected to the support shaft 31. A stamping die groove 3201 is opened on the upper and lower sides of the die base 32, aligned with the area below the stamping head 21. The tilting motor 33 is mounted on the electric lifting frame 3. The output shaft of the tilting motor 33 is fixedly connected to the support shaft 31. A... The device is equipped with an air supply channel 3101 structure; the support shaft 31 has several air outlets 3102 structures that connect to the air supply channel 3101; the mold base 32 has several first air jet holes 3202 that connect to the corresponding air outlets 3102, and the first air jet holes 3202 pass through the upper and lower stamping mold grooves 3201 respectively; an air supply valve 34 is fixedly connected to the electric lifting frame 3, and the air supply valve 34 is externally connected to a pressurized air supply device, and the air supply valve 34 is initially in a closed state; the air supply valve 34 is rotatably connected to the support shaft, and the air supply port 3401 of the air supply valve 34 connects to the air supply channel 3101 of the support shaft 31; a collection bucket 5 is placed on the mounting frame 1, and the collection bucket 5 is aligned with the lower part of the mold base 32.

[0019] like Figure 2 As shown, a limiting ring plate 4 is fixedly attached to the mounting bracket 1. The limiting ring plate 4 is initially in close contact with the upper surface of the die base 32. During the process of the stamping head 21 punching the metal sheet into the stamping die groove 3201 on the upper side of the die base 32, the die base 32 is restricted by the limiting ring plate 4 and will not cause the support shaft rod 31 to deflect. The limiting ring plate 4 provides a limiting fixation to prevent the die base 32 from overturning. An electric heating coil 41 for heating the area of ​​the metal sheet to be stamped is installed on the limiting ring plate 4.

[0020] Before use, the staff sets up the metal sheet conveying equipment under the stamping host 2, allowing the metal sheet conveying equipment to convey the various parts of the metal sheet sequentially between the stamping head 21 and the die base 32. Whenever a part of the metal sheet to be stamped aligns with the stamping die groove 3201 on the upper side of the die base 32, the part of the metal sheet to be stamped is pressed against the upper surface of the electric heating coil 41 of the limiting ring plate 4. The electric heating coil 41 quickly heats the part of the metal sheet to be stamped. Then, the stamping host 2 controls the stamping head 21 to press the part of the metal sheet to be stamped downward into the stamping die groove 3201 on the upper side of the die base 32, and a metal can bottom is obtained by stamping. Because the part of the metal sheet to be stamped is heated, the residual stress on the edge structure of the stamped metal can bottom is eliminated, preventing deformation and cracking.

[0021] After each metal can bottom is stamped, the stamping host 2 drives the stamping head 21 upwards away from the metal can bottom on the die base 32. The metal can bottom is then clamped in the stamping die groove 3201 on the upper side of the die base 32. At the same time, the electric lifting frame 3 moves the die base 32 and the metal can bottom downwards away from the limiting ring plate 4. Then, the tilting motor 33 drives the support shaft and the die base 32 to rotate 180 degrees, so that the metal can bottom is flipped to the lower side of the die base 32. At this time, the metal can... The bottom is held firmly in the stamping die groove 3201 on the lower side of the die base 32. Then, the electric lifting frame 3 promptly drives the die base 32 to return to its original position, so that the upper side of the die base 32 after flipping is in close contact with the limiting ring plate 4. The stamping host 2 drives the stamping head 21 to begin stamping the next metal can bottom in conjunction with the stamping die groove 3201 on the upper side of the die base 32. At the same time, the air supply valve 34 briefly switches to the open state, and the external pressurized air supply equipment supplies air to the support shaft through the air supply channel of the air supply valve 34. 3101 delivers pressurized airflow, which is ejected downwards through the air outlet 3102 of the support shaft and the first jet hole 3202 of the mold base 32. The pressurized airflow blows the bottom of the metal cans in the lower stamping mold groove 3201 of the mold base 32 downwards. The blown-out metal can bottoms are stacked downwards and collected in the collection bucket 5. This integrates the stamping action and demolding collection action, which were originally two separate workstations, into the same cycle of the mold base 32 flipping. This eliminates the need for additional guiding and transmission mechanisms and the transition space required for long-distance transport of the metal can bottoms, significantly reducing the overall footprint of the equipment. After flipping, the downward orientation of the lower stamping mold groove 3201 makes the can bottom fall off the path short and vertically controllable, which reduces energy consumption and failure rate, and ensures that the can bottoms fall into the bucket in a stable posture for neat stacking. This structure achieves the integration of stamping, flipping, demolding and stacking processes with minimal mechanical action, taking into account the simultaneous optimization of space utilization, operational reliability and production cycle.

[0022] Example 2, based on Example 1, such as Figures 1-5As shown, in this embodiment, a ring-shaped air passage 3203 structure is formed inside the mold base 32; a side through hole 3103 structure is formed on the support shaft 31, which connects to the air supply channel 3101 and is connected to the ring-shaped air passage 3203; a plurality of second jet holes 3204 structures are formed on the mold base 32, which connect to the ring-shaped air passage 3203 and respectively penetrate the upper and lower stamping die grooves 3201; a first partition 310 is provided in the middle of the air supply channel 3101 of the support shaft 31. 4. The first partition 3104 divides the air supply channel 3101, the air outlet 3102 and the side through hole 3103 into independent upper and lower areas; the mold base 32 is provided with a second partition 3205 structure, which divides the first jet hole 3202, the annular air passage 3203 and the second jet hole 3204 into independent upper and lower areas; the air supply port 3401 of the air supply valve 34 is connected to the lower area of ​​the air supply channel 3101; the collection bucket 5 is provided with a number of through holes 501 structures.

[0023] Each time the die holder 32 completes a 180-degree rotation of the stamped metal can bottom, the gas supply port 3401 of the gas supply valve 34 remains connected to the lower region of the gas supply channel 3101. After a brief switch to the open state, the pressurized airflow flows through the gas supply port 3401 of the gas supply valve 34 into the lower region of the gas supply channel 3101. The pressurized airflow flows through the lower region of the gas supply channel 3101 and the lower region of the first jet, and then is ejected downwards through the lower regions of the first jet hole 3202 and the second jet hole 3204. The pressurized airflow pushes the metal can bottom in the stamping die groove 3201 on the lower side of the die holder 32 downwards into the collection bucket 5. As the metal can bottom moves downwards along the inner wall of the collection bucket 5, it is ejected from the first jet hole 3202 and the second jet hole 3204. The pressurized airflow from the lower region of the two jet holes 3204 continuously blows onto the upper surface of the metal can bottom. At this time, the metal can bottom is in an inverted state, and the upper surface of the metal can bottom is inclined downwards in all directions. The pressurized airflow uses this inclined structure to naturally guide the airflow and blow away the stamping debris remaining on the edge structure of the metal can bottom. The stamping debris is discharged outwards through the through hole 501 of the collection bucket 5 with the pressurized airflow. This ensures that the stamping debris will not damage the surface or affect the flatness of the stacked metal can bottom as it is stacked. During this process, there is no upward blowing of pressurized airflow in the stamping die groove 3201 on the upper side of the die holder 32. This ensures that the metal can bottom in the stamping die groove 3201 on the upper side of the die holder 32 will not be affected by the pressurized airflow when the next metal can bottom is stamped simultaneously.

[0024] Example 3, based on Example 1, such as Figures 1-7As shown, in this embodiment, a guide ring 51 is fixedly attached to the collection bucket 5. After the metal can bottom that has been stamped off falls downward from the stamping die groove 3201 of the die base 32, the metal can bottom will align with the middle position of the collection bucket 5 along the inclined inner wall structure of the guide ring 51. The metal can bottom then falls precisely downward into the collection bucket 5, improving the neatness of the stacking of the metal can bottom in the collection bucket 5. The inner left and inner right sides of the guide ring 51 are respectively rotatably connected to a support plate 52 via a rotating shaft. An electric push rod 53 is installed on the left and right sides of the mounting frame 1. The telescopic ends of the two electric push rods 53 are respectively close to the support plate 52 on the same side. In the initial state, the telescopic ends of the electric push rods 53 push the support plate 52 to flip up in the direction of the guide ring 51 to an inclined state. A buffer block 54 is fixedly attached to the surface of each of the two support plates 52.

[0025] After the metal can bottom is stamped, the edge structure falls into the collection bucket 5 in an inverted state. Because the distance between the stamping die groove 3201 of the die base 32 and the collection bucket 5 is relatively long, when the metal sheet used for the metal can bottom is thin, the edge structure of the metal can bottom is prone to breakage when it falls downwards and collides with the inner wall of the collection bucket 5. Therefore, in this embodiment, before the metal can bottom falls into the collection bucket 5, the edge structure of the metal can bottom first contacts the buffer blocks 54 on the two support plates 52. 54 provides support and cushioning for the edge structure of the metal can bottom. Then, the electric push rod 53 retracts away from the support plate 52. Under the action of gravity, the support plate 52 naturally flips downward into a hanging state. The support plate 52 drives the buffer block 54 to flip downward and leave the metal can bottom. The metal can bottom then falls into the collection bucket 5 for stacking and collection. This ensures that the can bottom can fall into the collection bucket 5 in a stable and accurate manner for stacking and stacking. At the same time, it also provides structural protection for thin stamped metal materials under long-distance material dropping conditions.
