Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to an auxiliary feeding device for a rubber sheet bending machine. Background Technology

[0002] When processing sheet metal, a bending machine is generally required to bend the sheet metal according to processing needs. Bending machines can be divided into manual bending machines, hydraulic bending machines, and CNC bending machines. The bending machine achieves the bending and shaping of the sheet metal by moving the upper and lower dies and combining the shapes of the upper and lower dies. During the bending process, for some sheet metals with relatively light materials, such as rubber sheets and plastic sheets, the light material itself cannot fall smoothly from the bending working surface under the action of gravity after bending. The traditional method is to manually push the sheet metal to fall, which poses a significant safety hazard. Therefore, a material feeding device is needed to assist the sheet metal bending machine. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an auxiliary feeding device for a sheet bending machine, which solves the safety hazard caused by manually pushing the sheet to fall in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] An auxiliary feeding device for a rubber sheet bending machine includes:

[0006] The bending machine body has a feeding platform on the front side of the bending machine body, which is used to transport L-shaped plates into the bending working surface. The bending machine body has an unloading component on the rear side of the bending machine body, which allows the bent L-shaped plates to leave the bending working surface.

[0007] The unloading assembly includes an unloading plate slidably connected to the bending machine body. An unloading rod extending to the front side of the loading platform is provided on the unloading plate. The bending machine body is also provided with an unloading drive component. The unloading drive component drives the unloading plate to reciprocate towards the loading platform, so as to drive the unloading rod to push the bent sheet material off the loading platform.

[0008] To achieve the above technical solution, by setting up a material ejection component, the bent L-shaped sheet material can be removed from the bending working surface instead of manually, thereby avoiding the safety hazards that exist during manual operation.

[0009] The ejector drive mechanism reciprocates the ejector plate towards the loading platform. During bending, the ejector drive moves the ejector plate away from the loading platform, allowing the ejector rod to leave the bending surface and enabling the bending action to proceed normally. After bending, the ejector drive moves the ejector plate closer to the loading platform until the front end of the ejector rod contacts the sheet metal. The ejector rod pushes the bent portion of the sheet metal, causing it to tilt downwards. At this point, the ejector drive moves the ejector plate away from the loading platform. As the sheet metal tilts downwards, its center of gravity changes, allowing it to fall off the loading platform under gravity. Due to its size limitations, the ejector rod cannot support the sheet metal, so the sheet metal cannot rest on the ejector rod when it retracts.

[0010] In one embodiment of the present invention, an ejector support is provided on the ejector plate, the ejector support supports the ejector rod near the middle position, the ejector rod is hinged to the ejector support, and a rod drive is provided on the side of the ejector plate away from the loading platform, the rod drive drives the ejector rod to rotate around the ejector support to adjust the height of the ejector rod near the loading platform.

[0011] To achieve the above technical solution, by setting a material ejection support to support the material ejection rod, the stability of the material ejection rod during use can be improved. The material rod drive component drives the material ejection rod to rotate around the material ejection support. In actual use, the height of the material ejection rod's front end contacting the board can be adjusted as needed, thereby adapting to the ejection of different boards. Furthermore, during maintenance, the front end of the material ejection rod can be raised for convenient maintenance.

[0012] In one embodiment of the present invention, a material ejection slide rail is provided on the rear side of the bending machine body, and the material ejection plate is slidably connected to the material ejection slide rail.

[0013] To achieve the above technical solution, the material ejection slide rail can limit the sliding of the material ejection plate, thereby ensuring the sliding stability of the material ejection plate.

[0014] In one embodiment of the present invention, a feeding plate is provided on the side of the feeding platform near the bending machine body, the feeding plate extends to the working surface of the bending machine, and the lower side of the feeding plate is recessed away from the bending machine body.

[0015] To achieve the above technical solution, the feeding plate can be set to facilitate the support of the sheet metal. The lower side of the feeding plate is recessed away from the bending machine body, which can provide more displacement space when the unloading rod pushes the sheet metal to fall, thus ensuring the stability of the unloading action of the unloading rod.

[0016] In one embodiment of the present invention, a material plate base is provided between the bottom of the feeding plate and the feeding platform, and the width of the material plate base is smaller than the width of the feeding platform.

[0017] To achieve the above technical solution, by setting a material plate base and making the width of the material plate base smaller than the width of the loading platform, more sufficient material ejection displacement space can be provided for the ejection rod, ensuring the stability of the material ejection action.

[0018] In one embodiment of the present invention, a base support is provided between the loading platform and the material plate base. The base support is a trapezoidal support, and the inclined end of the trapezoidal support is located close to the bending machine body.

[0019] To achieve the above technical solution, by setting the base support as a trapezoidal support and placing the inclined end of the trapezoidal support close to one end of the bending machine body, more sufficient material ejection displacement space can be provided for the ejection rod, and the falling sheet metal can be prevented from getting stuck on the base support, thus ensuring the stability of the material ejection action.

[0020] In one embodiment of the present invention, an ejector plate is provided on the ejector plate near the ejector drive member. The ejector plate is a T-shaped plate, and the ejector drive member is movably connected to the ejector plate.

[0021] To achieve the above technical solution, by setting up a material ejection connecting plate, the material ejection drive component can be easily connected to the material ejection connecting plate, ensuring the synchronous drive of the material ejection drive component to the material ejection connecting plate.

[0022] As described above, the auxiliary unloading device for a sheet metal bending machine of this utility model has the following beneficial effects: by setting an unloading drive component to drive the unloading plate to reciprocate towards the upper loading table, when bending is performed, the unloading drive component drives the unloading plate to move away from the loading table, so that the unloading rod leaves the bending working surface, allowing the bending action to proceed normally. After the bending action is completed, the unloading drive component drives the unloading plate to move closer to the loading table until the front end of the unloading rod can contact the sheet metal. The unloading rod pushes the bent part of the sheet metal, causing the sheet metal to tilt downwards. At that time, the unloading drive component drives the unloading plate to move away from the loading table. After the sheet metal tilts downwards, its center of gravity changes, so it can fall off the loading table under the action of gravity. However, due to its own size limitations, the unloading rod cannot support the sheet metal. Therefore, when the unloading rod moves backwards, the sheet metal cannot sit on the unloading rod.

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please see Figures 1 to 3 This utility model provides an auxiliary unloading device for a sheet metal bending machine, including a loading platform 2 set on the front side of the bending machine body 1. The loading platform 2 is used to transport L-shaped sheet metal into the bending working surface. A material unloading component is set on the rear side of the bending machine body 1 to allow the bent L-shaped sheet metal to leave the bending working surface. The material unloading component includes a material unloading plate 3 slidably connected to the bending machine body 1. A material unloading rod 4 extending to the front side of the loading platform 2 is set on the material unloading plate 3. A material unloading drive component 5 is also set on the bending machine body 1. The material unloading drive component 5 drives the material unloading plate 3 to reciprocate towards the loading platform 2, so as to drive the material unloading rod 4 to push the bent sheet metal off the loading platform 2.

[0030] By setting up a material ejection component, the bent L-shaped sheet material can be removed from the bending work surface instead of manually, thus avoiding the safety hazards that exist during manual operation.

[0031] By setting the ejector drive 5 to drive the ejector plate 3 to reciprocate towards the upper loading platform 2, when bending is performed, the ejector drive 5 drives the ejector plate 3 to move away from the loading platform 2, so that the ejector rod 4 leaves the bending working surface, allowing the bending action to proceed normally. After the bending action is completed, the ejector drive 5 drives the ejector plate 3 to move closer to the loading platform 2 until the front end of the ejector rod 4 can contact the board. The ejector rod 4 pushes the bent part of the board, causing the board to tilt downward. At this time, the ejector drive 5 drives the ejector plate 3 to move away from the loading platform 2. After the board tilts downward, its center of gravity changes, so it can fall off the loading platform 2 under the action of gravity. However, due to its own size limitations, the ejector rod 4 cannot support the board. Therefore, when the ejector rod 4 moves backward, the board cannot sit on the ejector rod 4.

[0032] A material ejection plate 3 is provided with a material ejection support 6, which supports the material ejection rod 4 near the middle position. The material ejection rod 4 is hinged to the material ejection support 6. A material rod drive component 7 is provided on the side of the material ejection plate 3 away from the loading platform 2. The material rod drive component 7 drives the material ejection rod 4 to rotate around the material ejection support 6 to adjust the height of the end of the material ejection rod 4 near the loading platform 2.

[0033] By setting the ejector support 6 to support the ejector rod 4, the stability of the ejector rod 4 during use can be improved. The ejector rod 4 can be driven to rotate around the ejector support 6 by the rod drive component 7. The height of the ejector rod 4 in contact with the board can be adjusted as needed during actual use, so as to adapt to the ejection of different boards. In addition, the front end of the ejector rod 4 can be raised during maintenance, which facilitates maintenance.

[0034] A material ejection slide rail 8 is provided on the rear side of the bending machine body 1. The material ejection plate 3 is slidably connected to the material ejection slide rail 8. By setting the material ejection slide rail 8, the sliding of the material ejection plate 3 can be limited, thereby ensuring the sliding stability of the material ejection plate 3.

[0035] A feeding plate 9 is provided on the side of the feeding platform 2 near the bending machine body 1. The feeding plate 9 extends to the working surface of the bending machine. The lower side of the feeding plate 9 is recessed away from the bending machine body 1. The feeding plate 9 can facilitate the support of the sheet metal. The recessed lower side of the feeding plate 9 away from the bending machine body 1 can provide more displacement space when the ejector rod 4 pushes the sheet metal to fall, ensuring the stability of the ejector rod 4's ejection action.

[0036] A material plate base 10 is provided between the bottom of the feeding plate 9 and the feeding platform 2. The width of the material plate base 10 is smaller than the width of the feeding platform 2. By setting the material plate base 10 and making its width smaller than the width of the feeding platform 2, more space can be provided for the ejection rod 4 to eject material, thus ensuring the stability of the ejection action.

[0037] A base support 11 is set between the loading platform 2 and the material plate base 10. The base support 11 is a trapezoidal support, with the inclined end of the trapezoidal support close to the bending machine body 1. By setting the base support 11 as a trapezoidal support and placing the inclined end of the trapezoidal support close to one end of the bending machine body 1, more sufficient material ejection displacement space can be provided for the ejection rod 4, and the falling plate can be prevented from getting stuck on the base support 11, ensuring the stability of the material ejection action.

[0038] A material ejection plate 12 is provided on the ejection plate 3 near the ejection drive component 5. The material ejection plate 12 is a T-shaped plate. The ejection drive component 5 is movably connected to the material ejection plate 12. By setting the material ejection plate 12, the material ejection drive component 5 can be easily movably connected to the material ejection plate 12, ensuring the synchronous driving of the material ejection drive component 5 to the material ejection plate 12.

[0039] This invention utilizes a material ejection drive to reciprocate the ejection plate towards the upper loading platform. During bending, the ejection drive moves the ejection plate away from the loading platform, allowing the ejection rod to leave the bending working surface and enabling the bending action to proceed normally. After the bending action is completed, the ejection drive moves the ejection plate closer to the loading platform until the front end of the ejection rod contacts the sheet metal. The ejection rod then pushes the bent portion of the sheet metal, causing it to tilt downwards. At this point, the ejection drive moves the ejection plate away from the loading platform. As the sheet metal tilts downwards, its center of gravity changes, allowing it to fall off the loading platform under the influence of gravity. However, due to its size limitations, the ejection rod cannot support the sheet metal, so the sheet metal cannot rest on the ejection rod when it retracts.

[0040] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
