Description

Technical Field

[0001] The invention relates to the field of stamping, in particular to the field of automobile parts stamping, and in particular to an automobile stamping die which is convenient for cleaning waste materials. Background Art

[0002] When stamping auto parts, waste is inevitably generated. After stamping, the waste will fall into the cavity below and accumulate continuously. Therefore, the waste below needs to be cleaned regularly. Based on the search for waste cleaning of stamping dies, some existing technologies have been found, which are now introduced one by one:

[0003] First, a Chinese utility model patent with authorization announcement number CN218891097U discloses an automobile stamping die that facilitates waste cleaning. The waste is collected by a collection frame. When the waste needs to be removed, the collection frame is pulled out, and larger waste is manually disposed of. Then, smaller waste is pushed out by a push plate to achieve waste cleaning.

[0004] Second, a Chinese utility model patent with authorization publication number CN221734662U discloses a stamping die for facilitating waste collection, in which a motor drives a scraper to move left and right on a screw rod, scraping fertilizer into a collection trough.

[0005] It can be seen from this that in the existing technology, it is common to push the waste away by moving tools such as push plates to achieve the purpose of waste cleaning. However, this technology has some shortcomings when applied to the stamping die in the above video. For example: 1. Different automotive parts have different specifications of stamping dies, that is, the size of the cavity where the waste is located is different. The push plate technology cannot be applied to the waste cleaning of stamping dies of different specifications; 2. Most automotive parts used for stamping are metal parts. During stamping, metal waste continues to accumulate and eventually forms a shape similar to a conical hill. When the waste is pushed by the push plate, the waste at the bottom bears the gravity from the waste above. Therefore, a large metallic harsh sound will be generated, which will cause discomfort to the staff in the surrounding environment and affect hearing in the long run. In addition, over time, the metal waste at the bottom and the bottom of the cavity of the stamping die for stacking waste will produce scratches and wear, thereby further increasing the metallic harsh sound and affecting the pushing of the waste.

[0006] Based on the above, the present invention proposes an automobile stamping die that is convenient for cleaning waste. Summary of the Invention

[0007] To solve the problems mentioned in the above background, the present invention provides an automobile stamping die that is convenient for cleaning waste materials.

[0008] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows.

[0009] An automobile stamping die that facilitates cleaning of waste materials comprises a workbench on which a stamping die, a cleaning member, and a conveyor belt are arranged. A plurality of stamping stations are arranged in an array on the stamping die, and a lower chamber is provided below each stamping station. The conveyor belt and the cleaning member are respectively located on both sides of the stamping die.

[0010] The cleaning component includes a movable bracket, on which a longitudinal bracket and a driving member for driving the longitudinal bracket to move are provided, and the moving direction of the longitudinal bracket is parallel to the width direction of the stamping die;

[0011] A slide is slidably provided on the longitudinal support, and a moving direction of the slide is parallel to a moving direction of the longitudinal support. A first spring is provided between the slide and the longitudinal support, and the elastic force of the first spring drives the slide to move closer to the conveyor belt;

[0012] Two push plates are hingedly provided at one end of the longitudinal bracket facing the conveyor belt, and a connecting rod bracket is hingedly provided between the push plates and the slide seat. The two push plates are respectively located on both sides of the longitudinal bracket. Initially, the push plates face the side of the conveyor belt perpendicular to the moving direction of the longitudinal bracket.

[0013] As a further improvement and optimization of the present invention, two corresponding connecting rod brackets are provided, and the hinge axis formed at the hinge between the push plate and the longitudinal bracket, the hinge axis formed at the hinge between the connecting rod bracket and the push plate, and the hinge axis formed at the hinge between the connecting rod bracket and the slide seat are all arranged vertically.

[0014] As a further improvement and optimization of the present invention, a bottom plate is extended from the bottom of the lower chamber toward one side of the conveyor belt, the upper surface of the bottom plate is flush with the bottom of the lower chamber, and side plates are extended vertically upward on both sides of the bottom plate. The facing sides of the two side plates are respectively located in the same plane with the two cavity walls of the lower chamber along the width direction, and the suspended end of the bottom plate is located above the conveyor belt.

[0015] As a further improvement and optimization of the present invention, the driving member includes a rack arranged on the longitudinal bracket and a gear and a first motor arranged on the movable bracket. The extension direction of the rack is parallel to the moving direction of the longitudinal bracket, the gear is engaged with the rack, and the first motor and the gear form a power connection.

[0016] As a further improvement and optimization of the present invention, the cleaning component further includes a displacement component for driving the movable bracket to move in the vertical direction and along the length direction of the stamping die.

[0017] As a further improvement and optimization of the present invention, the shift assembly includes a fixed bracket provided on the workbench, wherein two fixed brackets are provided and are respectively close to the two ends of the stamping die, a horizontal bracket is slidably provided between the two fixed brackets, the moving direction of the horizontal bracket is arranged vertically, and a first linear module is provided on the fixed bracket for driving the horizontal bracket to move;

[0018] The movable bracket is slidably arranged on the transverse bracket, and the moving direction of the movable bracket is parallel to the length direction of the stamping die. The transverse bracket is provided with a second linear module for driving the movable bracket to move.

[0019] As a further improvement and optimization of the present invention, the slide is annular in shape, and a friction seat is provided on the longitudinal bracket for sliding in the vertical direction. The friction seat passes through the slide, and a second spring is provided between the friction seat and the longitudinal bracket. The elastic force of the second spring drives the friction seat to move away from the slide, and a second driving member is also provided on the longitudinal bracket. The second driving member is used to drive the friction seat to move closer to the slide.

[0020] As a further improvement and optimization of the present invention, the second driving member includes a screw whose extension direction is parallel to the moving direction of the longitudinal bracket and a second motor for driving the screw to rotate. A socket is provided on the outside of the screw, and the socket and the longitudinal bracket form a sliding connection along the moving direction of the longitudinal bracket. The socket is provided with a slope one and a slope two at the end of the friction seat. The slope one is in contact with the slope two. When the screw is rotated to drive the socket to move, the friction seat can be driven to move close to the sliding seat through the cooperation of the slope one and the slope two, so that the friction seat conflicts with the sliding seat.

[0021] As a further improvement and optimization of the present invention, a coil is provided on the longitudinal bracket, and a magnet is provided on the slide seat, and the magnet is located inside the coil.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In this solution, the lower chamber can be adapted to different sizes and specifications to push out the waste. Therefore, this solution has a wider scope of application and better versatility, solving the problem 1 mentioned in the background technology.

[0024] 2. During stamping, metal scraps will accumulate in the lower chamber into a hill-like shape. In this solution, the push plate needs to first deflect to adapt to the size of the lower chamber and enter the lower chamber before pushing the scraps out. The advantage is that the two push plates are arranged at an angle to enter the lower chamber. Therefore, during cleaning, the scrap hill will be pushed down first, and then pushed out. After the scrap hill is pushed down, the squeezing force on the scrap at the bottom due to the weight of the scrap above will become smaller. Therefore, in the subsequent process of pushing the scraps out, the noise will be significantly reduced, and the wear on the lower chamber caused by the movement of the scraps will also be reduced, solving the problem 2 mentioned in the background technology.

[0036] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0037] Reference Figures 1-9 , an automobile stamping die that is convenient for cleaning waste, includes a workbench 100, on which a stamping die 101, a cleaning component 200 and a conveyor belt 300 are arranged.

[0038] The stamping die 101 is provided with a plurality of stamping stations in an array, and a lower chamber 102 is provided under each stamping station. The waste materials dropped during stamping are stacked in the lower chamber 102. The stamping die 101 and the lower chamber 102 can be realized by existing technology and will not be described in detail.

[0039] The conveyor belt 300 and the cleaning component 200 are respectively located on both sides of the stamping die 101. A bottom plate 103 extends from the bottom of the lower chamber 102 toward the side of the conveyor belt 300. The upper surface of the bottom plate 103 is flush with the bottom of the lower chamber 102. Side plates 104 extend vertically upward on both sides of the bottom plate 103. The facing sides of the two side plates 104 are respectively located in the same plane with the two cavity walls of the lower chamber 102 along the width direction. The suspended end of the bottom plate 103 is located above the conveyor belt 300.

[0040] During use, the stamping process of automobile parts is realized through the stamping die 101. This is achievable with the existing technology and will not be elaborated. The waste generated by the stamping will fall into the lower chamber 102 and accumulate. The lower chamber 102 is regularly cleaned of waste by the cleaning component 200. The cleaned waste falls onto the conveyor belt 300 and is pulled away by the conveyor belt 300.

[0041] Reference Figure 4-Figure 9 The cleaning component 200 includes a cleaning component and a shifting component. The shifting component pulls the cleaning component to transfer between different lower chambers 102, and the cleaning component is used to clean the waste in the lower chamber 102.

[0042] Reference Figure 4 and Figure 5 The shift assembly includes a fixed bracket 201 arranged on the workbench 100, and two fixed brackets 201 are provided and are respectively close to the two ends of the stamping die 101, and a horizontal bracket 203 is slidably arranged between the two fixed brackets 201, and the moving direction of the horizontal bracket 203 is arranged vertically, and a first linear module 202 for driving the horizontal bracket 203 to move is provided on the fixed bracket 201, and a movable bracket 205 is slidably provided on the horizontal bracket 203, and the moving direction of the movable bracket 205 is parallel to the length direction of the stamping die 101, and a second linear module 204 for driving the movable bracket 205 to move is provided on the horizontal bracket 203; the first linear module 202 and the second linear module 204 adopt the existing electric telescopic rod technology or the existing screw linear motion technology, etc., which will not be repeated. Through the cooperation of the two, the lower surface of the cleaning end of the cleaning component arranged on the movable bracket 205 can be flush with the bottom of the lower chamber 102.

[0043] Reference Figure 6-Figure 9The cleaning component includes a longitudinal bracket 206 slidably arranged on the movable bracket 205, and the moving direction of the longitudinal bracket 206 is parallel to the width direction of the stamping die 101. The movable bracket 205 is provided with a driving member 1 for driving the longitudinal bracket 206 to move. Furthermore, the driving member 1 includes a rack 207 arranged on the longitudinal bracket 206 and a gear 208 and a first motor 209 arranged on the movable bracket 205. The extension direction of the rack 207 is parallel to the moving direction of the longitudinal bracket 206. The gear 208 is engaged with the rack 207, and the first motor 209 and the gear 208 are connected by power. Preferably, the power connection is formed by a worm gear, and the gear 208 is driven to rotate by the first motor 209, thereby driving the rack 207 to move, and the rack 207 moves with the longitudinal bracket 206.

[0044] A slide 211 is slidably provided on the longitudinal bracket 206 , and the moving direction of the slide 211 is parallel to the moving direction of the longitudinal bracket 206 . A first spring 213 is provided between the slide 211 and the longitudinal bracket 206 , and the elastic force of the first spring 213 is used to drive the slide 211 to move closer to the conveyor belt 300 .

[0045] Two push plates 210 are hingedly provided at one end of the longitudinal bracket 206 facing the conveyor belt 300, and a connecting rod bracket 212 is hingedly provided between the push plate 210 and the slide 211. There are two corresponding connecting rod brackets 212, and the hinge axis formed at the hinge between the push plate 210 and the longitudinal bracket 206, the hinge axis formed at the hinge between the connecting rod bracket 212 and the push plate 210, and the hinge axis formed at the hinge between the connecting rod bracket 212 and the slide 211 are all arranged vertically.

[0046] The two push plates 210 are respectively located on both sides of the longitudinal support 206 . Initially, the push plates 210 face the sides of the conveyor belt 300 and are perpendicular to the moving direction of the longitudinal support 206 .

[0047] The waste cleaning process of the lower chamber 102 is specifically as follows:

[0048] By driving the shifting assembly, the lower surface of the push plate 210 can be flush with the bottom of the lower chamber 102 and the opening of the lower chamber 102 is located between the two opposite sides of the push plates 210;

[0049] Then, the driving member drives the longitudinal bracket 206 to move closer to the conveyor belt 300. During this process, the push plate 210 will contact the opening of the lower chamber 102. Therefore, the push plate 210 will deflect backward, and the slide 211 will also retreat. The first spring 213 is compressed until the opposite sides of the two push plates 210 are in contact with the two cavity walls of the lower chamber 102 along the length direction of the stamping die 101. Then the longitudinal bracket 206 continues to move, and the waste in the lower chamber 102 is pushed out by the push plate 210, and finally falls onto the conveyor belt 300.

[0050] From this we can see that:

[0051] 1. In this solution, the lower chamber 102 of different sizes can be adapted to push out the waste. Therefore, this solution has a wider scope of application and better versatility, solving the problem 1 mentioned in the background technology.

[0052] 2. During stamping, metal waste will accumulate into a hill-like shape in the lower chamber 102. In this solution, the push plate 210 needs to first deflect to adapt to the size of the lower chamber 102 and enter the lower chamber 102, and then push the waste out. The advantage is that the two push plates 210 are arranged at an angle to enter the lower chamber 102. Therefore, during cleaning, the waste hill will be pushed down first, and then pushed out. After the waste hill is pushed down, the squeezing force on the bottom waste from the weight of the waste above will become smaller. Therefore, in the subsequent process of pushing the waste out, the noise will be significantly reduced, and the wear of the lower chamber 102 caused by the movement of the waste will also be reduced, solving the problem 2 mentioned in the background technology.

[0053] In a preferred embodiment, after the waste is pushed onto the conveyor belt 300, the driving member drives the longitudinal support 206 to retreat and reset. During this process, since there is a tendency for the two push plates 210 to reset and deflect, the push plates 210 are easily stuck when retreating. In addition, if there is too much metal waste, the push plates 210 are also prone to deflect when pushing the waste, so that there is a gap between the push plates 210 and the lower chamber 102, and some waste will leak from the gap, resulting in incomplete cleaning. In order to solve this problem, reference is made to FIG. Figure 8 and Figure 9 The slide 211 is annular in shape, and a friction seat 217 is provided on the longitudinal bracket 206 for sliding in the vertical direction. The friction seat 217 passes through the slide 211. A second spring 218 is provided between the friction seat 217 and the longitudinal bracket 206. The elastic force of the second spring 218 is used to drive the friction seat 217 to move away from the slide 211. A second driving member is also provided on the longitudinal bracket 206 for driving the friction seat 217 to move closer to the slide 211.

[0054] Furthermore, the second driving member includes a screw rod 215 extending in a direction parallel to the moving direction of the longitudinal bracket 206 and a second motor 214 for driving the screw rod 215 to rotate. A nested seat 216 is provided on the outside of the screw rod 215. The nested seat 216 is also connected to the longitudinal bracket 206 in a sliding manner along the moving direction of the longitudinal bracket 206. Therefore, the nested seat 216 can be driven to move by the second motor 214. The nested seat 216 is provided with a slope 1 and a slope 2 at the end of the friction seat 217. The slope 1 is in contact with the slope 2. When the nested seat 216 is driven to move by the second motor 214, the friction seat 217 can be driven to move close to the second motor 214 through the cooperation of the slope 1 and the slope 2. The movement of the slide 211 eventually causes the friction seat 217 to conflict with the slide 211. That is to say, after the push plate 210 adapts to the size of the lower chamber 102 and initially enters the lower chamber 102, the second motor 214 can be used to drive the friction seat 217 to conflict with the slide 211. The friction force between the two limits the push plate 210 so that it maintains its current state and no longer deflects. When cleaning is completed and the push plate 210 retreats and leaves the lower chamber 102, the second motor 214 drives the embedded seat 216 to retreat, the second spring 218 releases the elastic force, the friction seat 217 is out of conflict with the slide 211, and the first spring 213 releases the elastic force to reset the push plate 210.

[0055] In a preferred embodiment, since the sizes of different lower chambers 102 are different, the time point at which the push plate 210 initially enters the lower chamber 102 and adapts to the size of the lower chamber 102 is uncertain. Therefore, real-time monitoring can be performed using existing sensor technology to start the second motor 214 at the corresponding time, or by referring to Figure 9 A coil 219 is set on the longitudinal bracket 206, and a magnet 220 is set on the slide 211. In the process of the push plate 210 adapting to the size of the lower chamber 102 and gradually entering the lower chamber 102, the slide 211 moves with the magnet 220, thereby generating current. After initially entering the lower chamber 102, the slide 211 no longer moves and the current disappears. Based on this, it is possible to monitor the time point when the push plate 210 adapts to the size of the lower chamber 102 and initially enters the lower chamber 102. It should be noted that the current is used to monitor whether the magnet 220 moves, thereby indirectly monitoring whether the slide 211 moves, and finally reaching the time point when the push plate 210 adapts to the size of the lower chamber 102 and initially enters the lower chamber 102. Among them, detecting whether current occurs and whether the current disappears are both achievable by existing technologies and will not be elaborated on.

[0056] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
