Description

Technical Field

[0001] The utility model relates to the technical field of valve core pressing tooling, in particular to a valve core pressing tooling for producing solenoid valves. Background Art

[0002] Solenoid valve is an industrial device controlled by electromagnetics. It is a basic component for controlling fluid automation. It is an actuator and is not limited to hydraulic or pneumatic. It is used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, and the accuracy and flexibility of control can be guaranteed. The solenoid valve consists of two parts: the electromagnetic coil and the valve body. The main working principle is to use the electromagnetic force generated by the electromagnetic coil to push the valve core to achieve the on / off or reversing of the fluid.

[0003] Some valve cores are produced by pressing and forming. Some existing solenoid valve pressing tools usually use manual loading and ejection mechanisms below the pressing station to load and unload the material rod when used with vertical pressing devices. This method takes a long time to load and unload the material, resulting in a decrease in the production efficiency of the valve core pressing. Utility Model Content

[0004] The utility model mainly provides a valve core pressing tool for electromagnetic valve production, which solves the problem that the tooling in the prior art has a long loading and unloading time, resulting in reduced production efficiency of the valve core pressing.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A valve core pressing tool for solenoid valve production, comprising a linear displacement mechanism and a valve core pressing mechanism; a mounting seat is provided on the linear displacement mechanism, and the mounting seat is moved to the valve core pressing mechanism by the drive of the linear displacement mechanism; a stabilizing cylinder is provided on the mounting seat, and a pressing channel cooperating with the valve core pressing mechanism is provided on the stabilizing cylinder; a first mounting frame is provided at the feeding end of the stabilizing cylinder, and a lifting mechanism is provided on the first mounting frame, and a second mounting frame is provided at the discharging end of the stabilizing cylinder, and a material end limiting mechanism is provided on the second mounting frame; it also includes a feeding hopper for single feeding, and a feeding platform cooperating with the stabilizing cylinder is provided below the feeding hopper. When in use, the material rod is placed in the lower hopper, and then the material rod at the lower side can fall onto the feeding table. Due to the material induction rod on the feeding table, other material rods cannot fall; then the material rod on the feeding table is pushed into the stabilizing cylinder by the pushing mechanism, and the stabilizing cylinder with the material rod is driven to the pressing station by the linear displacement mechanism, and the material rod is pressed and formed from the opened pressing channel by the valve core pressing mechanism arranged on the pressing station. During the process, the front and rear ends of the material rod can be limited by the material end limiting mechanism in cooperation with the pushing mechanism. After the pressing is completed, the material end limiting mechanism is opened, and the material rod of the stabilizing cylinder is pushed out from the other end by the pushing mechanism, so as to facilitate the loading of the next material rod and the movement of the pressed material rod. By adopting the structure of the present application, the material rod can be driven from the feed table into the stabilizing cylinder through the material pushing mechanism, thereby realizing convenient loading; at the same time, the material rod can be fixed in line by the stabilizing cylinder, the material pushing mechanism and the material end limiting mechanism, so that it can be driven to move by the linear displacement mechanism, and the subsequent pressing mechanism can be convenient for accurately pressing the material rod to prevent dislocation; at the same time, stable unloading of the material rod can be realized through the lower hopper and the feed table.

[0007] Furthermore, the linear displacement mechanism includes two upright frames, a displacement screw threadedly connected between the two upright frames, a displacement guide rod fixedly connected between the two upright frames, and a motor for driving the displacement screw to rotate; the mounting seat is threadedly connected to the displacement screw, and the mounting seat is slidably connected to the displacement guide rod. With this structure, the displacement screw can be driven to rotate by the motor, thereby cooperating with the displacement guide rod to achieve displacement of the mounting seat, and the position movement is more accurate by using the screw.

[0008] Furthermore, a vertical guide rod is provided below the stabilizing cylinder, and a vertical guide hole matching the vertical guide rod is provided on the mounting seat. With this structure, when the valve core pressing mechanism presses the material rod from both sides, the stabilizing cylinder can be easily moved up and down, so that the two pressing blocks of the valve core pressing mechanism drive the material rod to move up and press the material rod, thereby preventing the two pressing blocks of the valve core pressing mechanism from stretching and damaging the connection seat between the stabilizing cylinder and the mounting seat when the mold is closed.

[0009] Furthermore, the ejection mechanism includes a first pushing cylinder horizontally mounted on the first mounting frame, and a ejection head is provided at the output end of the pushing cylinder. The first mounting frame is arranged below the feed table, so that the first mounting frame can be displaced to the bottom of the feed table, so that the first pushing cylinder can reach the outer end of the feed table, which is convenient for pushing the material rod. The feed table can be fixed in position by fixing the side end, so as to avoid the bracket arranged on the low side affecting the displacement of the first mounting frame. The setting of the ejection head can prevent the material rod in the discharge hopper from unloading when the material rod is pushed into the stabilizing cylinder, and the ejection head is located below the discharge opening, so that the material rod will fall only when the ejection head exits the feed table.

[0010] Furthermore, the material end limiting mechanism includes a second push cylinder vertically mounted on the second mounting frame, a limit stop lever is provided at the output end of the second push cylinder, and a rod hole for matching the limit stop lever is provided on the stabilizing cylinder. With this structure, the limit stop lever can be driven up and down by the second push cylinder, thereby limiting the end of the material rod, and opening the material discharge end of the stabilizing cylinder to realize material unloading.

[0011] Furthermore, a V-shaped feeding trough is provided in the feeding hopper, a feeding opening for passing a single feeding rod is provided at the lower end of the V-shaped feeding trough, and a V-shaped limiting groove is provided on the feeding platform. With this structure, only one feeding rod can be fed at a time, and after the feeding rod falls onto the V-shaped limiting groove of the feeding platform, the space between the upper end of the feeding rod and the feeding opening is not enough to allow the next feeding rod to fall from the side, thereby realizing stable feeding of a single feeding rod.

[0012] Beneficial effects: By adopting the structure of the present application, the material rod can be driven from the feed table into the stabilizing cylinder through the material pushing mechanism, thereby realizing convenient loading; at the same time, the material rod can be fixed in line by the stabilizing cylinder, the material pushing mechanism and the material end limiting mechanism, so that it can be driven to move by the linear displacement mechanism, and the subsequent pressing mechanism can be convenient for accurately pressing the material rod to prevent dislocation; at the same time, the stable unloading of the material rod can be realized through the lower hopper and the feed table.
