Description

Technical Field

[0001] The utility model relates to the technical field of cylinder jacking machines, in particular to a cylinder jacking machine steel outlet structure capable of reducing damage. Background Art

[0002] Cylinder ejector is a hydraulic device widely used in industrial production, especially in metal processing, molding process and plastic molding. The main function is to drive the workpiece in the mold to complete molding, punching, pressing and other operations through powerful hydraulic force, and demold the finished workpiece from the mold through the equipped steel structure. Cylinder ejector is mainly composed of the main body, hydraulic system, control system, cylinder, steel and auxiliary device parts. The main body includes a workbench, columns, guide rails, etc., which are used to support and fix various components. The hydraulic pump extracts the hydraulic oil from the oil tank, and after filtering and adjusting the valve block, it is delivered to the cylinder. The control system compresses the hydraulic oil by controlling the opening and closing of the valve, thereby pushing the piston in the cylinder up and down. When the piston moves downward, it applies pressure to the workpiece placed in the mold to complete molding or other processing tasks. After the processing is completed, the control system instructs the steel structure to work and push the workpiece out of the mold for removal, effectively improving production efficiency.

[0003] There are still some problems with the steel-discharging structure of the cylinder-discharging machine that is widely used at present. For example, a cylinder-discharging machine with the publication number CN 210387551U maintains a stable extrusion plate when sliding through a guide block and a guide groove, ensuring that the extrusion plate positively extrude the mold tube, so that the output shaft of the hydraulic cylinder can be on the same horizontal line as the metal tube in the mold tube. However, in the actual process of ejecting the workpiece and demoulding, the limit of the steel-discharging machine is inaccurate, so that the cylinder-discharging machine has a great impact on the equipment when it is in operation, and it is easy to hit the water beam, the ejector rod is severely worn and has a short service life, and the rod is easily broken and caused by production accidents.

[0024] See also Figure 1-4 A steel-extruding structure of a cylinder ejecting machine with reduced damage comprises a frame 1, a hydraulic cylinder 2 fixedly mounted on the top surface of the frame 1, a through groove being arranged on the top surface of the frame 1, a ejector rod 3 being fixedly connected to the output end of the hydraulic cylinder 2 and penetrating the through groove, and when the hydraulic cylinder 2 drives the ejector rod 3 to eject vertically downward, it is helpful to reduce the impact force between the ejector rod 3 and the workpiece mold, a connector 4 is threadedly connected to the bottom end of the ejector rod 3, a limiting cylinder 5 and a telescopic water pipe 6 are fixedly mounted on the top surface of the inner wall of the frame 1, four upright posts 7 are fixedly mounted inside the frame 1, and a clamping mechanism 8 and an electric supporting plate 9 are slidably connected to the surface of the upright posts 7.

[0025] Furthermore, the connecting head 4 is a conical structure. The conical structure combined with the limiting tube 5 can realize the precise limiting of the ejector rod 3 to avoid mechanical damage or production accidents caused by excessive ejection. There are multiple groups of connecting heads 4, and the inner wall and surface of each group of connecting heads 4 are provided with threads. The threaded connection between each group of connecting heads 4 is more stable and is not easy to collapse and break during ejection. The subsequent replacement of the connecting heads 4 has low maintenance costs.

[0026] Furthermore, the limiting cylinder 5 is perpendicular to the top surface of the inner wall of the frame 1, the center line of the push rod 3 coincides with the center line of the limiting cylinder 5, the cross-sectional diameter of the limiting cylinder 5 is larger than the cross-sectional diameter of the push rod 3, and a slot is provided at the bottom end of the inner wall of the limiting cylinder 5, and a spring is fixedly connected to the inner wall of the slot. There are two groups of springs, and each group of springs is fixedly connected to a clamping ring 10 at one end away from the slot. The clamping ring 10 is a semicircular ring structure, and there are two groups of clamping rings 10. The diameter of the clamping ring 10 is smaller than the cross-sectional diameter of the connecting head 4, which does not affect the lifting and lowering work of the connecting head 4 while being able to accurately limit and reduce impact.

[0027] Furthermore, the telescopic water pipe 6 forms an angle with the top surface of the inner wall of the frame 1. Two groups of telescopic water pipes 6 are provided, and are distributed in a mirror-symmetrical manner with the limiting cylinder 5 as the center line. The intersection point of the water beams sprayed by the two groups of telescopic water pipes 6 is located directly below the limiting cylinder 5, thereby preventing the water beams from directly impacting the top rod 3 and the connecting head 4.

[0028] Furthermore, the clamping mechanism 8 includes an electric lifting plate, a clamping plate 12, a movable plate 13 and a gripper 14. The surface of the column 7 is slidably connected with the electric lifting plate. The electric lifting plate is a T-shaped structure. The T-shaped structure connects two groups of columns. When the clamping mold is lifted and lowered in parallel, it is more stable and not easy to deviate. There are two groups of electric lifting plates, which are mirror-symmetrically distributed. One end of each group of electric lifting plates close to the limiting cylinder 5 is rotatably connected with the clamping plate 12. The clamping plate 12 is a semicircular structure. The side of the clamping plate 12 close to the limiting cylinder 5 is rotatably connected with the movable plate 13. Two groups of movable plates 13 are arranged, and are distributed parallel to each other. The side of the movable plate 13 close to the limiting cylinder 5 is rotatably connected with the gripper 14. Four groups of grippers 14 are arranged, and are distributed parallel to each other. The clamping plate 12 cooperates with the movable plate 13 and the gripper 14 to rotate and clamp irregular molds more stably and has strong applicability.

[0029] Furthermore, a plurality of groups of water leakage holes are provided on the top surface of the electric support plate 9 and penetrate through its bottom surface. A water storage tank is provided at the bottom of the frame 1 to realize secondary utilization after the workpiece is demoulded by water beam flushing assistance. A water pump and a water pipe are provided inside the column 7. The input end of the water pump is fixedly connected to the water storage tank through the water pipe, and the output end of the water pump is fixedly connected to the telescopic water pipe 6. Recycling is beneficial to reducing production costs.

[0030] When in use, the mold opening is facing downward and inverted at the center of the electric support plate 9. The electric lifting plate is started to drive the two groups of clamping plates 12 to rise and fall to the height of the center of the mold, and the mold is clamped left and right. The four groups of grippers 14 on the left and right sides are closely fitted with the mold surface to complete the mold fixing process. A circular incision with a diameter larger than the connector 4 is opened at the center of the mold using a slotting tool. After the workpiece surface is exposed, the bottom ends of the two groups of telescopic water pipes 6 are aligned with the circular incision, and the water pump is started to inject the water beam into the gap between the workpiece and the mold. Then, the water pump is turned off, and the hydraulic cylinder 2 is started to drive the ejector rod 3 to vertically eject the limiting cylinder 5 along the through groove. While contacting the workpiece surface, the electric support plate 9 is started to slowly descend. While not affecting the ejection of the workpiece by the connector 4 at the bottom end of the ejector rod 3, the inner wall bottom groove of the limiting cylinder 5 elastically connects the connector 4 with the retaining ring 10 through a spring to accurately limit the ejector rod 3. When the workpiece is demoulded, the hydraulic cylinder 2 drives the ejector rod 3 to shrink, and drives the retaining ring 10 to shrink along the inclined surface of the tapered connector 4 toward the inner wall of the groove.
