Description

Technical Field

[0001] The invention belongs to the technical field of shearing machines, and in particular relates to a chassis processing shearing machine for stably fixing metal plates. Background Art

[0002] Shearing machine is a common metal processing machinery and equipment, mainly used for shearing metal plates. It uses blades to shear metal plates, and is suitable for various materials, such as steel plates, stainless steel plates, aluminum plates, etc. Shearing machines are widely used in steel, machinery, construction, automobile and other industries. The working principle of shearing machine is mainly to use blades to shear metal plates under pressure. The shearing process can be divided into the following steps: feeding: the plate is pushed to the shearing position; shearing: the upper blade and the lower blade move relative to each other at a certain angle to shear the metal plate; material withdrawal: the sheared plate is discharged from the equipment.

[0003] There are many different types of shearing machines on the market. Although they can all achieve metal plate shearing, they still have defects. When the existing shearing machines are shearing metal plates, most of them use bevel knife groups for shearing, which makes the sheared metal plates prone to bending and deformation, especially the deformation of metal plates with poor elasticity is the most significant. In order to ensure the subsequent normal use, it is often necessary to use leveling equipment to perform secondary processing on the sheared metal plates, which is not only time-consuming and labor-intensive, but also affects the overall production and processing progress. In addition, most of the existing shearing machines are semi-automatic equipment, lacking automatic feeding mechanisms and limiting and fixing of metal plates. When shearing, feeding and shearing operations are usually performed manually, which is very inefficient and will also affect the overall production and processing quality and processing accuracy to a certain extent. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a chassis processing shearing machine that can stably fix metal plates.

[0005] The technical solution adopted to solve the above technical problems is: a chassis processing shearing machine for fixing and stably processing metal plates, comprising a main frame, the main frame comprising a fixed frame, the top of the fixed frame is fixedly connected with a supporting top seat, the rear end of the fixed frame is provided with a shearing groove, and the top of one side of the rear end of the fixed frame is provided with a lifting slide groove;

[0006] The front end of the main frame is fixedly connected with a feeding support mechanism, on which an automatic feeding mechanism for conveying metal plates is installed, and a guide limiting mechanism is also installed on the top of the feeding support mechanism;

[0007] A hydraulic shearing mechanism for shearing metal plates is installed on the support top seat;

[0008] An automatic leveling mechanism is installed in the shearing groove for automatically leveling the metal plate after shearing.

[0009] Furthermore, a control panel is installed on the top of one side of the fixed frame.

[0010] Through the above technical solution, the control panel is used for integrated control of the equipment, and its input end is electrically connected to other actuators through wires, thereby controlling each actuator to work to achieve stable operation of the equipment.

[0011] Furthermore, the feeding support mechanism includes a feeding platform fixed to the front end of the fixed frame, the bottom of the feeding platform is fixedly connected to the support frame, the top of the feeding platform is provided with a motor slot near the front end, and a protective cover is installed on the motor slot.

[0012] Through the above technical scheme, the feeding support mechanism is mainly used to support and place the metal sheet to be processed. In conjunction with the automatic feeding mechanism and the guide limit mechanism, the metal sheet can be accurately fed to the shearing processing position to ensure high stability and high-precision shearing processing.

[0013] Furthermore, the automatic feeding mechanism includes two symmetrical rectangular holes located on the feeding platform, and the front and rear ends between the inner walls of the two rectangular holes are respectively rotatably connected with a driving roller and a driven roller, and a plurality of auxiliary rollers are also rotatably connected between the inner walls of the two rectangular holes. Conveyor belts are installed between the two groups of driving rollers, driven rollers and multiple auxiliary rollers, and a double-headed driving motor is installed in the motor slot. Transmission shafts are fixedly connected to the output shafts at both ends of the double-headed driving motor, and the other ends of the two transmission shafts are respectively connected to the corresponding driving rollers.

[0014] Through the above technical scheme, the automatic feeding mechanism can hold up the metal sheet and stably feed it to the shearing processing position. During processing, the operator or the manipulator places the metal sheet to be processed horizontally on the top of the feeding platform. Since there are two conveyor belts on the feeding platform, and the height of the two conveyor belts is slightly higher than the horizontal height of the feeding platform, when the double-headed drive motor is started, the two corresponding drive rollers can be driven to rotate synchronously through the two transmission shafts, and then the two conveyor belts can be driven synchronously to operate synchronously, thereby driving the metal sheet placed on the top of the conveyor belt to move in a directional manner. The forward movement of the metal sheet can be set through the control panel, which not only realizes the automatic feeding function, but also ensures the processing accuracy.

[0015] Furthermore, the guide limit mechanism includes two groups of T-slots opened on both sides of the top of the feeding platform, and limit frames are installed on both sides of the top of the feeding platform. A T-bolt is slidably installed in each of the T-slots, and each of the T-bolts is threadedly connected with a first locking knob for locking the corresponding limit frame. Adjustment holes are opened at the rear ends of the two limit frames, and a double-headed threaded fixing shaft is installed between the two adjustment holes. A plurality of rotating pressure wheels are rotatably connected to the double-headed threaded fixing shaft, and both ends of the double-headed threaded fixing shaft are threadedly connected with a second locking knob for locking the height of the double-headed threaded fixing shaft.

[0016] Through the above technical scheme, the guide limit mechanism is mainly used for limiting and fixing the relative position of metal plates of different sizes. For metal plates of different widths, the spacing between the two limit frames can be adjusted, and then the positions of the two limit frames can be locked and fixed by two sets of T-bolts and the first locking knob; at the same time, a double-headed threaded fixing shaft is installed between the two adjustment holes, and a plurality of rotating pressure wheels are rotatably connected to the double-headed threaded fixing shaft. The heights of the plurality of rotating pressure wheels can also be adjusted on the two adjustment holes to adapt to metal plates of different thicknesses. After the adjustment is completed, the height position can be locked and fixed by two second locking knobs. The plurality of rotating pressure wheels can cooperate with the automatic feeding mechanism to limit the metal plate in the vertical direction. Under the action of the vertical limit, the metal plate can be further pushed to the shearing position stably by friction. At the same time, during the shearing process of the metal plate, the plurality of rotating pressure wheels can press and fix the metal plate to ensure stability during the shearing process and prevent it from offsetting or shaking.

[0017] Furthermore, the hydraulic shearing mechanism includes two hydraulic cylinders installed on the top of the supporting top seat, the bottom ends of the two hydraulic cylinder piston rods are fixedly connected to a shearing seat, a shearing knife group is fixedly installed on the shearing seat, limit sliders are provided on both sides of the shearing seat, and sliding grooves matching the limit sliders are opened on both sides of the inner wall of the fixed frame.

[0018] Through the above technical solution, during processing, when the metal sheet moves to the shearing position, the piston rods of the two hydraulic cylinders will drive the shearing seat and the shearing knife group to move downward synchronously, thereby completing the shearing processing of the metal sheet. The bottom shearing surface of the shearing knife group also adopts a bevel design, so that the metal sheet can complete the shearing processing smoothly; in addition, the design of the limit slider and the slide groove can further ensure the shearing accuracy of the shearing knife group.

[0019] The top of the horizontal slide is fixedly connected with the second rotating support, and the top of the horizontal slide is fixedly connected with the second rotating support, and the supporting rod is rotatably connected with the first rotating support.

[0020] Through the above technical solution, since the bottom shearing surface of the shearing knife group is designed with an inclined surface, the shearing process is also completed slowly and continuously from one side to the other during the shearing process. Under normal conditions, the top plane of the rotating support platform is flush with the middle support plane of the fixed frame. When the shearing knife group starts cutting, the shearing knife group starts shearing from one side of the metal plate. During this process, the rotating support platform will rotate with the rotating support shaft as a fulcrum under the pressure of the shearing knife group. At the same time, the rotating support platform will push the horizontal slide to slide in the horizontal slide groove through the supporting connecting rod, and the horizontal slide will further squeeze the second return spring during the movement. During the continuous shearing process, the rotating support platform will further rotate, and the second return spring will also be further squeezed. When the shearing knife group completely cuts off the metal plate, the bottom surface of the shearing knife group will cooperate with the rotating support The platform clamps and fixes the sheared metal plate, and the shearing knife group will continue to move down a short distance. At this time, the lifting slide will also move downward and squeeze the first return spring until the first return spring and the second return spring are compressed to the critical limit position. In this process, the strong up and down extrusion force will quickly flatten and shape the sheared metal plate, thereby completing the leveling work; when the shearing and leveling are completed, the shearing knife group will automatically rise and reset. Due to the loss of the downward pressure of the shearing knife group, the first return spring and the second return spring will also push the rotating support platform in the opposite direction to slowly reset. When the shearing knife group is completely separated from the rotating support platform, the sheared metal plate will generally remain on the rotating support platform. When the subsequent metal plates continue to be fed, the sheared metal plates will be pushed backwards, causing them to naturally fall onto the receiving table, and then slide to the designated position through the receiving table for centralized collection.

[0021] Furthermore, the lifting slide seat is slidably limited in the lifting slide slot, and a fixed cover plate is also installed on the top of the lifting slide slot.

[0022] Through the above technical solution, the lifting slide groove can limit the lifting of the lifting slide, and the fixed cover plate can further limit the top of the lifting slide to ensure that the lifting slide can only slide in the lifting slide groove.

[0023] Furthermore, the installation groove is located on a side away from the lifting slide groove, the horizontal slide seat is slidably installed in the horizontal slide groove through the installation groove, and the horizontal slide seat is sleeved on the outer wall of the horizontal guide rod.

[0024] Furthermore, a material receiving platform is fixedly connected to the rear end of the fixed frame near the bottom.

[0025] Through the above technical solution, the receiving table serves as an intermediate platform, which can guide the metal plates that fall after shearing to a designated location for centralized collection.

[0026] The beneficial effects of the present invention are as follows: (1) The present invention can ensure the support stability of the metal plate during the shearing process by designing an automatic leveling mechanism, and can also synchronously complete the leveling of the metal plate after the shearing is completed, thereby avoiding subsequent secondary processing and saving a lot of manpower and material resources; (2) The present invention can realize the automatic feeding function by designing an automatic feeding mechanism, and the conveyor belt can drive the metal plate to move in a directional manner. The forward movement amount of the metal plate can be set through the control panel, which not only realizes the automatic feeding function but also ensures the processing accuracy; (3) The present invention can be used for limiting and fixing the relative position of metal plates of different sizes by designing a guide limit mechanism. For metal plates of different widths, the distance between the two limit frames can be quickly adjusted. At the same time, the design of multiple rotating pressure wheels can press and fix the metal plate to ensure stability during the shearing process. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] When the shearing knife group 503 is cutting, the shearing knife group 503 will start shearing from one side of the metal plate 8. During this process, the rotating support platform 606 will rotate with the rotating support shaft 605 as the fulcrum under the pressure of the shearing knife group 503. At the same time, the rotating support platform 606 will push the horizontal slide 613 to slide in the horizontal slide groove 609 through the supporting connecting rod 615, and the horizontal slide 613 will further squeeze the second return spring 612 during the movement. When the shearing knife group 503 completely cuts off the metal plate 8, the bottom surface of the shearing knife group 503 will cooperate with the rotating support platform 606 to clamp and fix the sheared metal plate, and the shearing knife group 503 will continue to move down a short distance. At this time, the lifting slide 603 will also move downward and squeeze the first return spring 602 until the first return spring 602 and the second return spring 612 are compressed to the critical limit position. During this process, the strong up and down squeezing force will quickly flatten and shape the sheared metal plate, thereby completing the leveling work;

[0056] When the shearing knife group 503 rises and resets, and is completely separated from the rotating support platform 606, the sheared metal plate will generally remain on the rotating support platform 606. When the subsequent metal plate 8 continues to be fed, the sheared metal plate will be pushed backward, so that it will naturally fall onto the receiving platform 7, and then slide to the designated position through the receiving platform 7 for centralized collection.
