Description

Technical Field

[0001] This utility model relates to the field of corner code cutting sawing machine technology, and in particular to an automatic feeding mechanism for corner code cutting sawing machine. Background Technology

[0002] An angle bracket cutting saw is a device used for cutting angle brackets (also known as angle irons), typically used in the manufacture of woodworking or metal products. Angle bracket cutting saws are usually equipped with saw blades, allowing for precise cutting of angle brackets to meet specific size and angle requirements. Currently, existing technologies for feeding angle brackets in angle bracket cutting saws often use a pushing cylinder or push rod to apply thrust. However, during the feeding process, the cutting end of the angle bracket is clamped and positioned by a pressure plate to fix the feeding length. When clamping and fixing the angle bracket, it is prone to deformation under the thrust, leading to reduced cutting accuracy.

[0003] For example, the automatic feeding mechanism of a corner code cutting saw disclosed in Chinese patent literature (announcement number: CN222133665U) uses two ratchet plates on the mounting block tilted towards the worktable and springs installed to provide rotational force. This allows the corner code profile to be pushed towards the worktable by friction pads on the ratchet plates, thus avoiding the possibility of deformation of the corner code profile due to the pushing force and improving the product yield.

[0004] However, during the pushing process, the ratchet plate uses the spring force to limit the corner code on both sides, and the upper clamping plate applies pressure to the upper corner code to fix it. Therefore, a large pushing force is required during pushing, which can easily cause the spring to fail to stably limit the corner code when it deviates, thus reducing the subsequent cutting accuracy. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Currently, when corner codes are pushed and fed, the elastic force of the spring makes it difficult to stably limit the two sides of the corner code, which easily leads to deviation and reduces cutting accuracy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automatic feeding mechanism for a corner code cutting saw includes a cutting saw body, a feeding table fixedly connected to the front of the cutting saw body, and a limit pushing mechanism provided above the feeding table. The limiting and pushing mechanism includes a support plate. A first hydraulic cylinder is fixedly installed on the front of the support plate. One end of the piston rod of the first hydraulic cylinder passes through the support plate and is fixedly connected to a movable plate. A guide rod symmetrically distributed is slidably sleeved on the inner wall of the movable plate. One end of each of the two guide rods is fixedly connected to a push plate. A pressure fixing mechanism is provided above the loading platform.

[0007] Preferably, the push plate has mounting grooves on both sides, and the inner wall of the mounting groove is hinged to a swing rod by a pin. One end of the swing rod is fixedly connected to a limit clamp.

[0008] Preferably, the other end of the swing rod is hinged to a drive rod via a pin, and one end of the drive rod is hinged to a support via a pin.

[0009] Preferably, the front of both supports is fixedly connected to the back of the movable plate, and a corner bracket support block is fixedly connected to the upper end of the loading platform.

[0010] Preferably, the pressure fixing mechanism includes a fixed bracket, both ends of which are fixedly connected to the upper end of the loading platform, and a second hydraulic cylinder is fixedly installed on the upper end of the fixed bracket.

[0011] Preferably, one end of the piston rod of the second hydraulic cylinder passes through the fixed bracket and is fixedly connected to a pressing fixed frame. The inner walls of both sides of the pressing fixed frame are provided with symmetrically distributed limiting grooves, and the inner walls of the limiting grooves are slidably connected to limiting sliders.

[0012] Preferably, a support spring is fixedly connected to the upper end of the limiting slider, one end of the support spring is fixedly connected to the inner top wall of the limiting groove, and a pressing wheel is rotatably connected to the opposing surfaces of the two limiting sliders through a bearing.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the limiting and pushing mechanism, through the linkage between the drive rod and the swing rod, drives the limiting clamp to rigidly limit the corner code on both sides during the pushing process, thereby avoiding the displacement of the corner code during elastic limiting. The pressure fixing mechanism pre-fixes the upper end of the corner code with its pressing wheel, which not only reduces friction during the pushing process, but also stably fixes the corner code after pushing, thereby improving the subsequent cutting accuracy.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] Example like Figure 1-4As shown, this utility model provides a technical solution: an automatic feeding mechanism for a corner code cutting saw, including a cutting saw body 1, a feeding platform 2 fixedly connected to the front of the cutting saw body 1, and a limit pushing mechanism and a pressure fixing mechanism respectively provided above the feeding platform 2, which is adapted to the automated production of the corner code cutting saw and improves the feeding accuracy and cutting stability.

[0021] The cutting saw body 1 is a mature existing technology, so it will not be described in detail.

[0022] A support plate 3 is fixed above the feeding platform 2. A first hydraulic cylinder 31 is installed on the front of the support plate 3. Its piston rod passes through the support plate 3 and is connected to the movable plate 32. The first hydraulic cylinder 31 serves as a power source and can precisely drive the movable plate 32 to move horizontally along the guide rod 33, providing a stable thrust for the pushing and clamping action of the corner code. It is the power basis for realizing automatic feeding.

[0023] The inner wall of the movable plate 32 is slidably fitted with guide rods 33 that are symmetrically distributed. One end of the guide rod 33 is fixed to a push plate 34. The push plate 34 has mounting grooves 35 on both sides. The grooves are hinged to a swing rod 36 through a pin. One end of the swing rod 36 is fixed to a limiting clamp 37, and the other end is hinged to a drive rod 38. The end of the drive rod 38 is hinged to a support 39, and the support 39 is fixed to the movable plate 32.

[0024] When the first hydraulic cylinder 31 pushes the movable plate 32 forward, the drive rod 38, in conjunction with the swing rod 36, swings around the pin of the mounting groove 35, causing the limit clamping block 37 to close synchronously on both sides of the diagonal code for clamping and limiting, avoiding the problem of easy deviation of the elastic limit, realizing the rigid clamping limit, and ensuring the stability of the corner code pushing direction. When the first hydraulic cylinder 31 retracts and drives the movable plate 32 to reset, the drive rod 38, in conjunction with the swing rod 36, swings in the opposite direction around the pin of the mounting groove 35, thereby causing the limit clamping block 37 to open synchronously and cancel the limit on both sides of the diagonal code.

[0025] The upper end of the feeding platform 2 is fixed with corner support block 310, which provides a horizontal support surface for the stacked corners, so that the corners maintain a horizontal posture during the pushing and clamping process, and avoid tilting or deformation due to unstable support. It is the basic load-bearing structure for stable feeding of corners.

[0026] The upper end of the loading platform 2 is fixed with a fixed bracket 4. A second hydraulic cylinder 41 is installed on the upper end of the bracket. Its piston rod passes through the bracket and is connected to the pressing and fixing frame 42. The second hydraulic cylinder 41 drives the pressing and fixing frame 42 to rise and fall vertically, which can realize the elastic pre-pressing and rigid fixing action of the corner code respectively, and provide power for the vertical limit of the corner code.

[0027] Limiting grooves 43 are opened on the inner walls of both sides of the pressing and fixing frame 42. Limiting sliders 44 are slidably connected in the grooves. Support springs 45 are connected to the upper end of the sliders. The other end of the support springs 45 is fixed to the top wall of the groove.

[0028] When the pressing bracket 42 descends, the support spring 45 first undergoes elastic deformation, causing the pressing wheel 46 to lightly press the upper end of the corner code, thus achieving elastic pre-compression. On the one hand, this avoids deformation of the corner code caused by rigid impact, and on the other hand, it utilizes the rolling characteristics of the pressing wheel 46 to reduce frictional resistance when pushing the corner code. As it continues to descend, the support spring 45 is compressed to its limit, providing stroke buffer for the rigid contact of the lower end face of the pressing bracket 42 with the corner code.

[0029] The limiting slider 44 is rotatably connected to the pressing wheel 46 via a bearing. When pushing, the pressing wheel 46 rolls into contact with the corner code, adapting to the surface shape of the corner code, ensuring smooth advancement of the corner code while avoiding scratching the corner code.

[0030] During the elastic pre-compression stage, the pressing roller 46 provides initial limiting to prevent the corner code from moving up and down; during the rigid fixing stage, the pressing fixing frame 42 makes hard contact with the corner code, and combined with the lateral constraint of the limiting clamp 37, the corner code is fixed in all dimensions, laying a stable foundation for the cutting operation.

[0031] The working process of this utility model: Step 1: Stack the corner pieces to be processed sequentially on top of the corner piece support block 310. The corner pieces are kept horizontally by the support block. Start the second hydraulic cylinder 41. The piston rod extends and drives the pressing and fixing frame 42 to descend. The pressing wheel 46 first contacts the uppermost corner piece. The support spring 45 is compressed to generate elastic pre-pressure, realizing the initial limiting of the corner piece. Start the first hydraulic cylinder 31. The piston rod extends and drives the movable plate 32 to move forward. The drive rod 38 pushes the swing rod 36 to move around the pin of the mounting groove 35, thereby driving the limiting clamp 37 to swing relative to each other, realizing the clamping and limiting of the corner piece on both sides. Step two: The first hydraulic cylinder 31 continuously pushes the movable plate 32, and the push plate 34 contacts the end of the corner code. With the centering constraint of the limiting clamp 37, the corner code is smoothly pushed along the corner code support block 310 into the cutting saw body 1 at the end of the loading table 2. During the push, the pressing wheel 46 rolls and follows to reduce frictional resistance and ensure that the corner code does not deviate. After the corner code is pushed into place, the second hydraulic cylinder 41 continues to extend, and the pressing fixing frame 42 compresses the support spring 45 and continues to descend until the lower end face of the pressing fixing frame 42 rigidly contacts the upper end of the corner code. Combined with the lateral constraint of the limiting clamp 37, the corner code is fixed in all dimensions, providing a stable foundation for the cutting operation.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
