Description

Technical Field

[0001] This utility model belongs to the field of punch press technology and relates to a scrap material receiving device for punch presses. Background Technology

[0002] In the automobile production process, many parts need to be processed using punch presses. Moreover, the requirements for punch presses vary depending on the shape and size of the parts. For example, smaller and simpler parts can be processed by a single or a few punch presses, while larger and more specialized parts require a larger punch press and multiple punch presses working in succession.

[0003] During the punching process, some waste material is often generated. For example, during the first step of punching, a ring-shaped waste material is often produced, while the middle part is processed in the first step. This waste material is usually thrown into a hopper next to the punch press. After the waste material in the hopper accumulates to a certain amount, sometimes a trolley is used to drag the hopper to a waste recycling area to empty the waste. However, in some production sites, due to limited space, workers need to manually remove the waste material from the hopper, load it into a trolley, and then manually drag the trolley out of the production area. In the latter case, because the hopper is quite deep, workers have to bend over and reach their hands into the hopper to remove the waste material, resulting in poor operational efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a waste material receiving device for punch presses, aiming to solve the problem of poor operation results.

[0005] To solve the above-mentioned technical problems, this utility model provides a scrap material receiving device for punch presses, comprising:

[0006] A fixed base plate is rectangular, and a first fixing plate and a second fixing plate are vertically arranged on the top of the fixed base plate. The cross-sections of the first fixing plate and the second fixing plate are L-shaped.

[0007] The first rotating column and the second rotating column are both vertically arranged on the top of the fixed base plate;

[0008] A first rotating cylinder and a second rotating cylinder, wherein a plurality of first rotating cylinders are rotatably arranged vertically on the outer wall of the first rotating column, and a plurality of second rotating cylinders are rotatably arranged vertically on the outer wall of the second rotating column;

[0009] A first rotating plate and a second rotating plate are provided on the side of each first rotating cylinder and a second rotating plate are provided on the side of each second rotating cylinder.

[0010] A positioning mechanism is provided to fix the free ends of the first rotating plate and the second rotating plate at the same height. The fixed base plate, the first fixed plate, the first rotating plate and the second rotating plate can form an upward-opening receiving space.

[0011] The present invention is further configured such that the top of both the first fixing plate and the second fixing plate are provided with a reinforcing part, and the top of the first rotating column and the second rotating column are respectively fixedly connected to one of the reinforcing parts.

[0012] The present invention is further configured such that a first terminating portion with an arc-shaped cross-section is vertically arranged on the inner side of the first fixing plate, and a second terminating portion with an arc-shaped cross-section is vertically arranged on the inner side of the second fixing plate. The first rotating cylinder is movably fitted to the inner side of the first terminating portion, and the second rotating cylinder is movably fitted to the inner side of the second terminating portion. When the free ends of the first rotating plate and the second rotating plate are fixedly connected, the first rotating plate abuts against the first terminating portion, and the second rotating plate abuts against the second terminating portion.

[0013] The present invention is further configured such that rolling elements are rotatably provided at the top of the first rotating cylinder, the bottom of the first rotating cylinder located at the bottom, the top of the second rotating cylinder, and the bottom of the second rotating cylinder located at the bottom. The rolling elements are used to move and abut against each other between adjacent first rotating cylinders, between the top first rotating cylinder and the corresponding reinforcing part, between the bottom first rotating cylinder and the fixed base plate, between adjacent second rotating cylinders, between the top second rotating cylinder and the corresponding reinforcing part, and between the bottom second rotating cylinder and the fixed base plate.

[0014] The present invention is further configured such that the positioning mechanism includes a positioning seat disposed on the outside of the first rotating plate, a rotating column disposed on the outside of the positioning seat, a positioning block rotatably connected to the outer wall of the rotating column, the length of the positioning block being greater than the width of the positioning seat, a telescopic member slidably connected to the side of the positioning block, and a positioning hole for inserting the telescopic member is provided on the positioning seat.

[0015] The free end of the second rotating plate is provided with a vertical part perpendicular to the second rotating plate. A clearance opening is provided on the vertical part. When the positioning block is in a horizontal state, rotating the second rotating plate can cause the positioning block, the positioning seat and the telescopic member to pass through the clearance opening until the vertical part is attached to the outside of the first rotating plate. When the positioning block is in a vertical state, the positioning block abuts against the outside of the vertical part, and the telescopic member can be inserted into the positioning hole by moving it.

[0016] The present invention is further configured such that a third termination portion is provided on the outer side of the vertical portion, and the top of the positioning block on the side opposite to the first rotating column abuts against the third termination portion.

[0017] The present invention is further configured such that the side of the positioning block is provided with two telescopic rails, both of which have an L-shaped cross section, and the telescopic member is provided with telescopic parts on both sides, and the two telescopic parts are respectively movably attached to the inner side of the two telescopic rails.

[0018] The present invention is further configured such that an operating part perpendicular to the telescopic member is provided at the outer end of the telescopic member, and an anti-detachment part is provided between the outer ends of the two telescopic rails.

[0019] Compared with existing technologies, this utility model provides a waste material receiving device for punch presses. When receiving stamping waste, the free ends of all the first and second rotating plates are fixedly connected. The cross-sections of the first and second rotating plates, the first fixed plate, and the second fixed plate are rectangular or nearly rectangular, thus forming an upward-opening shape to accommodate the waste material together with the fixed base plate. When cleaning the internal waste, the highest first and second rotating plates are opened first, and then the waste above them is cleaned; alternatively, depending on the actual situation, the corresponding layers of first and second rotating plates can be opened after cleaning; or the waste close to the first and second rotating plates can be cleaned first and then opened for cleaning. In any of these cases, the required cleaning depth is relatively low, thus reducing the cleaning difficulty. After the higher waste is cleaned, the lower waste is cleaned sequentially. This eliminates the need for workers to bend over excessively, reducing operational convenience and intensity, and improving operational efficiency. Meanwhile, since the adjacent sides of the fixed base plate (i.e. the sides where the first rotating plate and the second rotating plate are located) can be fully opened, the waste is cleaned more thoroughly. At the same time, during the cleaning process, the first fixed plate and the second fixed plate can also limit the waste to prevent it from spilling, which also makes the waste cleaning effect and operation effect better.

[0020] It should also be understood that the application is intended for use in situations where the site is limited and it is difficult or impossible to drive a vehicle to tow a fixed base plate or other structure. Attached Figure Description

[0030] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the scrap material receiving device for punch presses proposed in this utility model. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0031] A scrap material receiving device for punch presses, such as Figures 1 to 8 As shown, it includes:

[0032] A fixed base plate 1 is rectangular, and a first fixed plate 2 and a second fixed plate 3 are vertically arranged on the top of the fixed base plate 1. The cross-sections of the first fixed plate 2 and the second fixed plate 3 are L-shaped.

[0033] The first rotating column 4 and the second rotating column are both vertically arranged on the top of the fixed base plate 1;

[0034] The first rotating cylinder 5 and the second rotating cylinder 6 are arranged in a vertically distributed manner on the outer wall of the first rotating column 4.

[0035] A first rotating plate 7 and a second rotating plate 8 are provided on the side of each first rotating cylinder 5, and a second rotating plate 8 is provided on the side of each second rotating cylinder 6.

[0036] A positioning mechanism is provided to fix the free ends of the first rotating plate 7 and the second rotating plate 8 at the same height. The fixed base plate 1, the first fixed plate 2, the first rotating plate 7 and the second rotating plate 8 can form an upward-opening accommodating space.

[0037] The top of both the first fixing plate 2 and the second fixing plate 3 is provided with a reinforcing part 9, and the top of the first rotating column 4 and the second rotating column are respectively fixedly connected to one of the reinforcing parts 9.

[0038] The inner side of the first fixing plate 2 is vertically provided with a first terminating part 10 with a circular arc cross-section, and the inner side of the second fixing plate 3 is vertically provided with a second terminating part 11 with a circular arc cross-section. The first rotating cylinder 5 is movably attached to the inner side of the first terminating part 10, and the second rotating cylinder 6 is movably attached to the inner side of the second terminating part 11. When the free ends of the first rotating plate 7 and the second rotating plate 8 are fixedly connected, the first rotating plate 7 abuts against the first terminating part 10, and the second rotating plate 8 abuts against the second terminating part 11.

[0039] Rolling elements 12 are rotatably provided at the top of the first rotating cylinder 5, the bottom of the first rotating cylinder 5 located at the bottom, the top of the second rotating cylinder 6, and the bottom of the second rotating cylinder 6 located at the bottom. The rolling elements 12 are used to move and abut against each other between adjacent first rotating cylinders 5, between the top first rotating cylinder 5 and the corresponding reinforcing part 9, between the bottom first rotating cylinder 5 and the fixed base plate 1, between adjacent second rotating cylinders 6, between the top second rotating cylinder 6 and the corresponding reinforcing part 9, and between the bottom second rotating cylinder 6 and the fixed base plate 1.

[0040] The positioning mechanism includes a positioning seat 13 disposed on the outside of the first rotating plate 7, a rotating column 14 disposed on the outside of the positioning seat 13, a positioning block 15 rotatably connected to the outer wall of the rotating column 14, the length of the positioning block 15 being greater than the width of the positioning seat 13, a telescopic member 16 slidably connected to the side of the positioning block 15, and a positioning hole 17 for the telescopic member 16 to be inserted into the positioning seat 13.

[0041] The free end of the second rotating plate 8 is provided with a vertical part 18 perpendicular to the second rotating plate 8. The vertical part 18 is provided with a clearance opening 19. When the positioning block 15 is in a horizontal state, rotating the second rotating plate 8 can cause the positioning block 15, the positioning seat 13 and the telescopic member 16 to pass through the clearance opening 19 until the vertical part 18 is attached to the outside of the first rotating plate 7. When the positioning block 15 is in a vertical state, the positioning block 15 abuts against the outside of the vertical part 18, and the telescopic member 16 can be inserted into the positioning hole 17 by moving it.

[0042] A third termination part 20 is provided on the outer side of the vertical part 18, and the top of the positioning block 15 on the side opposite to the first rotating column 4 abuts against the third termination part 20.

[0043] The positioning block 15 has two telescopic rails 21 with L-shaped cross sections on its side. The telescopic component 16 has telescopic parts 22 on both sides, and the two telescopic parts 22 are respectively movably attached to the inner side of the two telescopic rails 21.

[0044] The outer end of the telescopic member 16 is provided with an operating part 23 perpendicular to the telescopic member 16, and an anti-detachment part 24 is provided between the outer ends of the two telescopic rails 21.

[0045] The scrap receiving device for punch presses provided by this utility model has all the free ends of the first rotating plate 7 and the second rotating plate 8 fixedly connected when receiving stamping scrap. The cross-sections of the first rotating plate 7, the second rotating plate 8, the first fixed plate 2, and the second fixed plate 3 are rectangular or nearly rectangular, thus forming an upward-opening shape to accommodate the scrap together with the fixed base plate 1. When cleaning the internal scrap, the highest first rotating plate 7 and the second rotating plate 8 are opened first, and then the scrap above are cleaned; or, depending on the actual situation, the corresponding layer of first rotating plates 7 and the second rotating plate 8 can be opened after cleaning; or the scrap close to the first rotating plate 7 and the second rotating plate 8 can be cleaned first and then opened for cleaning. In any of these cases, the required cleaning depth is relatively low, thus reducing the cleaning difficulty. After the higher scrap is cleaned, the lower scrap is cleaned sequentially. This eliminates the need for workers to bend over excessively, reducing operational convenience and intensity, and improving operational efficiency. Meanwhile, since the adjacent sides of the fixed base plate 1 (i.e. the sides where the first rotating plate 7 and the second rotating plate 8 are located) can be fully opened, the waste is cleaned more thoroughly. At the same time, during the cleaning process, the first fixed plate 2 and the second fixed plate 3 can also limit the waste to prevent it from spilling, which also makes the waste cleaning effect better.

[0046] It should also be understood that the application is intended for use in situations where the site is limited and it is difficult or impossible to drive a vehicle to tow the fixed base plate 1 and other structures.

[0047] In actual use, the positioning block 15 is in a vertical state, and the inner side of the positioning block 15 abuts against the outer side of the vertical part 18, while the inner side of the vertical part 18 abuts against the outer side of the first rotating plate 7. Therefore, the free ends of the first rotating plate 7 and the second rotating plate 8 are fixedly connected, which can limit the waste material.

[0048] When opening the first rotating plate 7 and the second rotating plate 8, the operating part 23 needs to be pulled outward first. This causes the telescopic member 16 and the two telescopic parts 22 to move outward. At the same time, the telescopic parts 22 are guided by the telescopic rail 21, thus maintaining stable movement. After the telescopic member 16 disengages from the positioning hole 17 (the two are slightly interference-fitted), rotate the positioning block 15 to a horizontal position. At this time, the second rotating plate 8 can be rotated outward directly. The positioning block 15, positioning seat 13, telescopic member 16, operating part 23, etc. can all pass directly through the clearance opening 19. After the second rotating plate 8 is opened, the first rotating plate 7 can also be opened directly. After all the waste is cleaned up, first rotate the first rotating plate 7 until it touches the first termination part 10 and can no longer rotate. Then rotate the second rotating plate 8 until it touches the second termination part 11. At the same time, the vertical part 18 also fits against the outside of the first rotating plate 7, and the second rotating plate 8 also touches the end of the first rotating plate 7. Then, rotate the positioning block 15 to a vertical position and insert the telescopic member 16 into the positioning hole 17 to fix the first rotating plate 7 and the second rotating plate 8. When the positioning block 15 is actually rotated, it reaches the third termination part 20, indicating that it has reached a vertical position, preventing the rotation angle from being too large or too small. Furthermore, throughout the entire use, the anti-detachment part 24 prevents the telescopic member 16 and the telescopic part 22 from disengaging from the telescopic rail 21.

[0049] The first termination part 10 and the second termination part 11 not only serve as limiters to prevent the first rotating plate 7 and the second rotating plate 8 from rotating too much, but also act as a barrier to prevent waste material from being inserted into the gaps between the first rotating cylinder 5 and the first fixed plate 2, and between the second rotating cylinder 6 and the second fixed plate 3. This ensures that the first rotating plate 7 and the second rotating plate 8 can rotate normally and easily, while also preventing waste material from getting stuck and making it difficult to clean.

[0050] The reinforcing part 9 enhances the structural strength and operational stability of the first and second rotating columns 4 and 6. The rolling element 12 (spherical or cylindrical) minimizes resistance between the first and second rotating cylinders 5 and 6 and the structures above and below, making the rotation of the first and second rotating plates 7 and 8 easier. Simultaneously, the inner wall of the first rotating cylinder 5 movably fits against the outer wall of the first rotating column 4, and the inner wall of the second rotating cylinder 6 movably fits against the outer wall of the second rotating column. This eliminates the need for bearings and other structural components, saving costs and reducing the likelihood of damage.

[0051] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

[0052] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
