Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pilot head sleeve stamping technology, specifically relating to a stamping device for pilot head sleeve processing. Background Technology
[0002] In the pneumatic field, the pilot head is one of the core components of a solenoid valve. The main structure of the pilot head includes a copper sleeve (also called a magnetic shielding sleeve), a stationary iron core, a moving iron core, a coil assembly, and a moving iron core spring. The copper sleeve is fixedly connected to the valve seat of the solenoid valve. The stationary iron core is fixedly housed inside the copper sleeve, while the moving iron core is movably housed inside the copper sleeve. The coil assembly is fixedly sleeved on the outside of the copper sleeve, and the moving iron core spring is housed inside the copper sleeve and engages with the moving iron core. By controlling the energization of the coil assembly, the moving iron core can be activated accordingly, thereby controlling the opening and closing of the solenoid valve or switching the fluid flow path.
[0003] Copper bushings typically require stamping during production. Currently, the dies used for stamping copper bushings on the market often have suboptimal structural designs. For example, the fit between the stamping head and die in some dies is not precise enough, which can easily lead to uneven bushing wall thickness during stamping, resulting in areas that are too thin or too thick, affecting the bushing's mechanical strength and magnetic shielding properties. Furthermore, the positioning structure of the dies is not precise enough, making the bushing prone to shifting during stamping, leading to excessive dimensional deviations and a high scrap rate.

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.
[0023] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a stamping device for processing a pilot head sleeve includes a worktable 1, a stamping platform 2 on the worktable 1, a stamping mechanism 3 above the stamping platform 2, and a fixed frame 31 on the worktable 1. A hydraulic cylinder 32 is mounted on the fixed frame 31, and a stamping block 33 is connected to the output end of the hydraulic cylinder 32.
[0024] This utility model proposes a stamping device for processing pilot head sleeves. The worktable 1 serves as the basic support component of the entire stamping device, providing a platform for the installation and fixation of other components, and is the main load-bearing body of the entire device. The stamping platform 2 is set on the worktable 1 and is the specific working plane for placing the pilot head sleeve to be processed, providing a suitable processing position for the stamping operation.
[0025] The stamping mechanism 3 is the core component for completing the stamping action. Installed above the stamping platform 2, it includes a mounting bracket 31 fixed to the worktable 1, which supports and secures the hydraulic cylinder 32, ensuring its stability during operation. The hydraulic cylinder 32, mounted on the mounting bracket 31, is the power source for the stamping mechanism 3, powered by a hydraulic system to achieve reciprocating motion. The stamping block 33 is connected to the output end of the hydraulic cylinder 32 and, driven by the hydraulic cylinder 32, moves up and down with it, directly stamping the pilot head sleeve placed on the stamping platform 2.
[0026] When the stamping device is in operation, the pilot head sleeve to be processed is first placed on the stamping platform 2 on the workbench 1, ensuring its accurate positioning for the stamping operation. Then, the hydraulic system is activated, and the hydraulic cylinder 32 begins to work. The hydraulic oil inside the cylinder 32, under pressure, pushes the piston, causing the output end of the cylinder 32 to extend downwards. Since the stamping block 33 is connected to the output end of the hydraulic cylinder 32, it moves downwards along with the downward movement of the hydraulic cylinder 32's output end, applying pressure to the pilot head sleeve placed on the stamping platform 2 to achieve the stamping process. After the stamping action is completed, the hydraulic cylinder 32 reverses its movement, retracting its output end upwards, causing the stamping block 33 to move upwards and away from the stamped pilot head sleeve. At this point, the processed product can be removed, ready for the next stamping operation.
[0027] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the stamping platform 2 includes a fixed base 21 set on the workbench 1. The fixed base 21 has a placement groove 22. The placement groove 22 is provided with a fixing mechanism 23 for fixing the pilot head sleeve. A fixing column 24 is provided at the center of the placement groove 22.
[0028] Specifically, the fixed base 21 is the basic support structure of the stamping platform 2. It is installed on the worktable 1 to provide stable support for the entire stamping platform 2, ensuring that it will not shake or shift due to external forces during the stamping process, thus guaranteeing the accuracy and stability of the processing.
[0029] The placement groove 22 is provided on the fixed base 21. The function of the placement groove 22 is to provide a special and precise placement position for the pilot head sleeve, so that the sleeve can be accurately positioned on the stamping platform 2, which facilitates subsequent fixing and stamping operations.
[0030] The fixing mechanism 23, located inside the placement slot 22, is a key component for securing the pilot head sleeve. Its design aims to ensure that the pilot head sleeve does not move or wobble due to the stamping force during the stamping process, thereby guaranteeing the stamping accuracy and quality. The fixing mechanism 23 may take various forms, such as spring clamping devices, pneumatic clamps, or threaded locking, depending on the shape, size, and processing requirements of the pilot head sleeve.
[0031] The fixing post 24 is located at the center of the placement groove 22. The function of the fixing post 24 is to further position and support the pilot head sleeve. The shape and size of the fixing post 24 match the internal structure of the pilot head sleeve. When the sleeve is placed in the placement groove 22, the fixing post 24 can be inserted into the sleeve, so that the sleeve is accurately positioned in both the horizontal and vertical directions, ensuring the positional accuracy of the sleeve during stamping.
[0032] When stamping the pilot head sleeve, the pilot head sleeve is first placed in the placement groove 22 of the stamping platform 2. Since the placement groove 22 is specially designed according to the shape and size of the sleeve, the sleeve can be smoothly placed into the groove. At this time, the fixing post 24 located in the center of the placement groove 22 will be inserted into the sleeve to initially position and support the sleeve, so that the sleeve remains stable in the horizontal direction.
[0033] Next, the fixing mechanism 23, which is located inside the placement groove 22, begins to operate. The fixing mechanism 23 secures the sleeve in the placement groove 22, thereby ensuring that the sleeve does not move in the vertical direction.
[0034] Once the pilot head sleeve is accurately fixed on the stamping platform 2, the stamping mechanism 3 of the stamping device begins to operate, performing stamping processing on the sleeve. Because the stamping platform 2 is stably mounted on the worktable 1 via the fixed base 21, and the pilot head sleeve is accurately fixed by the placement slot 22 and the fixing mechanism 23, the sleeve will not shift during the stamping process, thus ensuring the accuracy and quality of the stamping process and enabling the production of pilot head sleeve products that meet design requirements.
[0035] Combination Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the fixing mechanism 23 includes cylinders 231 that are disposed opposite to each other at both ends of the placement groove 22, and the output end of the cylinders 231 is connected to a fixing clamp 232.
[0036] Specifically, there are two cylinders 231, positioned opposite each other at both ends of the placement slot 22. The cylinders 231 provide power to the fixing blocks 232 and are the power source components of the fixing mechanism 23. Each cylinder 231 has a fixing block 232 connected to its output end. The shape and material of the fixing block 232 are designed according to the characteristics of the pilot head sleeve. Its surface in contact with the sleeve typically has a certain degree of friction and a suitable shape to ensure a firm grip on the sleeve while avoiding damage.
[0037] Combination Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the top of the fixing block 232 is provided with a fixing groove 233 that matches the outer periphery of the pilot head sleeve.
[0038] Specifically, the fixing groove 233 is located at the top of the fixing block 232 and is a special structure that matches the outer periphery of the pilot head sleeve. The shape of the fixing groove 233 is strictly designed according to the outer periphery of the pilot head sleeve, and may be circular, elliptical, polygonal, or other special shapes to ensure a tight fit with the outer periphery of the sleeve. At the same time, the surface of the fixing groove 233 is usually finely processed, such as grinding and polishing, to increase its surface smoothness, reduce frictional resistance with the sleeve, and avoid scratches or other damage to the sleeve surface during fixing and stamping.
[0039] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the bottom of the stamping block 33 is provided with a stamping groove 331, and the inner walls on both sides of the stamping groove 331 are provided with guide ramps.
[0040] Specifically, the stamping block 33 is typically made of a high-strength, high-hardness metal material, such as alloy tool steel. This material possesses excellent wear resistance, impact resistance, and hot hardness, enabling it to maintain shape and dimensional stability during multiple stamping processes, ensuring the precision and quality of the stamping process. The stamping groove 331, located at the bottom of the stamping block 33, is the core working area for stamping the pilot head sleeve. The shape and size of the stamping groove 331 are precisely designed according to the required shape and size of the pilot head sleeve, and may be circular, square, irregular, or other shapes, to ensure that the sleeve is formed to meet design requirements during the stamping process. Guide ramps are located on the inner walls of both sides of the stamping groove 331, and are sloping structures that gradually incline inward from the opening of the stamping groove 331. The inclination angle and length of the guide ramps are carefully designed, and their surfaces are typically smoothed to reduce friction when in contact with the pilot head sleeve.
[0041] Combination Figure 1 , Figure 2 and Figure 3 As shown, a switch button 4 is provided on the workbench 1.
[0042] Specifically, the switch button 4 is set on the surface of the workbench 1. Its specific position is usually reasonably arranged according to ergonomic principles and ease of operation. It is generally located in a place that is easy for the operator to reach and within sight, so that the operator can operate it at any time.
[0043] Combination Figure 1 , Figure 2 and Figure 3 As shown, a control panel 5 is installed on the workbench 1.
[0044] Specifically, the control panel 5 is set on the workbench 1. Its position is usually arranged in accordance with the principles of ergonomics, and is generally located in a position that is easy for the operator to observe and operate, so as to facilitate parameter adjustment and equipment control at any time during the processing.
[0045] Combination Figure 1 , Figure 2 and Figure 3 As shown, support legs 6 are provided around the bottom of the workbench 1.
[0046] Specifically, the support legs 6 are installed around the bottom of the worktable 1 and are key components to ensure the stability of the worktable 1 and the entire stamping device. Typically, four support legs 6 are installed, located at the four corners of the bottom of the worktable 1. This ensures that the worktable 1 is evenly stressed and receives good support in all directions, effectively preventing the worktable 1 from tilting or wobbling due to uneven stress.
[0047] Some support legs 6 are equipped with adjustment devices, such as threaded adjustment mechanisms. Threads are provided on the upper or lower part of the support leg 6, allowing its height to be adjusted by rotating it. This design enables the worktable 1 to be leveled on uneven surfaces, ensuring that the surface of the worktable 1 is level and thus guaranteeing the processing accuracy of the stamping device.
[0048] To increase the friction between the support leg 6 and the ground and prevent the workbench 1 from sliding, an anti-slip pad is usually installed on the bottom of the support leg 6. The anti-slip pad is generally made of materials such as rubber and has good anti-slip performance.
[0049] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
