Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder guide sleeve processing technology, specifically a wear-resistant hydraulic cylinder guide sleeve processing and forming machine. Background Technology

[0002] Wear-resistant hydraulic cylinder guide sleeves are an important component of hydraulic systems, primarily used to fix and guide the piston rod, ensuring the normal movement of the piston within the cylinder. The size and model of the guide sleeve directly affect the performance and stability of the hydraulic cylinder. In the initial processing stage, the high-temperature guide sleeve raw material is initially formed by stamping using a forming device. Some forming devices have guide sleeve molds on their bases, and stamping components are located at the top of the forming device via hydraulic rods. During the initial forming of the cylinder guide sleeve, the high-temperature cylinder guide sleeve raw material is placed into the mold, and then... The telescopic end of the pressure rod allows the stamping component to perform preliminary processing and shaping of the high-temperature hydraulic cylinder guide sleeve material inside the mold. After the hydraulic cylinder guide sleeve is preliminarily processed and shaped, the operator needs to remove it from the mold using pliers. Since most of the lower end of the hydraulic cylinder guide sleeve is located inside the mold, the operator can only perform the unloading operation by clamping the exposed upper part when unloading the hydraulic cylinder guide sleeve with pliers. Most of the weight of the hydraulic cylinder guide sleeve is located inside the mold, which is not conducive to the operator adjusting the unloading clamping point according to its weight distribution. Therefore, we propose a wear-resistant hydraulic cylinder guide sleeve processing and forming machine. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a wear-resistant hydraulic cylinder guide sleeve processing and forming machine. This device can automatically push the initially formed wear-resistant hydraulic cylinder guide sleeve out of the corresponding mold by the worker applying pressure with his feet and using the lever principle through the transmission element. Moreover, each component can be automatically reset by the elastic element in the later stage, so that the worker can adjust the clamping point of the wear-resistant hydraulic cylinder guide sleeve according to the weight distribution of the wear-resistant hydraulic cylinder guide sleeve with iron pliers, thereby facilitating the unloading operation of the initially formed wear-resistant hydraulic cylinder guide sleeve, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant hydraulic cylinder guide sleeve processing and forming machine, including a bottom shell, a stamping head installed at the upper end of the bottom shell, a mold provided in the middle of the upper side of the bottom shell, and a feeding mechanism;

[0005] The unloading mechanism includes a top material seat, a vertical slide rod, a foot pedal linkage assembly, and a reset assembly. The top material seat is slidably connected to the mold cavity. A vertical slide rod is provided on the lower side of the top material seat. The lower end of the vertical slide rod passes through a circular hole opened in the middle of the mold and the bottom shell. A foot pedal linkage assembly is provided between the bottom shell and the vertical slide rod. A reset assembly is provided between the foot pedal linkage assembly and the bottom shell. This device can automatically push the initially formed wear-resistant hydraulic cylinder guide sleeve out of the corresponding mold by applying pressure with the operator's foot and using the lever principle through the transmission element. Moreover, each component can be automatically reset by the elastic element in the later stage, so that the operator can adjust the clamping point of the wear-resistant hydraulic cylinder guide sleeve with iron pliers according to the weight distribution of the wear-resistant hydraulic cylinder guide sleeve, thereby facilitating the unloading operation of the initially formed wear-resistant hydraulic cylinder guide sleeve.

[0006] Furthermore, it also includes a microcontroller, which is located outside the bottom shell. The input terminal of the microcontroller is electrically connected to an external power supply, which facilitates the control of electrical components inside the device.

[0007] Furthermore, a top frame is provided on the upper side of the bottom shell via four evenly distributed support rods. A lifting seat is provided in the middle of the top frame via the telescopic end of an electro-hydraulic actuator. The input end of the electro-hydraulic actuator is electrically connected to the output end of the microcontroller. The lower middle part of the lifting seat is fixedly connected to the upper side of the stamping head. The corners of the lifting seat are slidably connected to the adjacent support rods through through holes, thus performing preliminary stamping forming of the wear-resistant hydraulic cylinder guide sleeve.

[0008] Furthermore, the foot pedal linkage assembly includes a U-shaped seat 1, a rotating shaft 1, a connecting rod 1, a U-shaped seat 2, a rotating shaft 2, a connecting rod 2, a foot pedal, and a clearance groove.

The lower side of the vertical slide rod is provided with a U-shaped seat 2. The interior of the U-shaped seat 2 and the right end of the connecting rod 1 are both rotatably connected to the rotating shaft 2 via a bearing 1. The connecting rod 2 is located between the two rotating shafts 2. A clearance groove is provided at the lower end of the front wall of the bottom shell. The front end of the connecting rod 1 passes through the clearance groove and is provided with a foot pedal. Stepping on the foot pedal realizes the lifting operation of the linkage cylinder guide sleeve of the top material seat.

[0009] Furthermore, the reset assembly includes a tension spring and a spring. The spring is disposed between the top wall of the bottom shell and the upper surface of the U-shaped seat II. The spring is movably sleeved on the outside of the vertical slide rod. A tension spring is provided between the lower right end of the connecting rod I and the bottom wall of the bottom shell, so that the foot pedal linkage assembly and other components in the wear-resistant hydraulic cylinder guide sleeve processing and forming machine can automatically reset after movement.

[0010] Furthermore, the feeding mechanism also includes a dovetail groove and a movable guard. The dovetail groove is located at the lower front end of the bottom shell, and the movable guard is slidably connected inside the dovetail groove. The movable guard is installed in conjunction with the foot pedal to protect the foot pedal inside the wear-resistant hydraulic cylinder guide sleeve processing and forming machine from accidental contact.

[0011] Furthermore, a laser sensor is provided on the upper right side of the lifting seat. The laser sensor is bidirectionally electrically connected to the microcontroller to detect and upload the vertical movement distance of the stamping head in the wear-resistant hydraulic cylinder guide sleeve processing and forming machine.

Moreover, each component can be automatically reset later through elastic elements, which makes it convenient for the worker to adjust the clamping points of the wear-resistant hydraulic cylinder guide sleeve according to the weight distribution of the wear-resistant hydraulic cylinder guide sleeve, thereby facilitating the unloading operation of the initially formed wear-resistant hydraulic cylinder guide sleeve.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This embodiment provides a technical solution: a wear-resistant hydraulic cylinder guide sleeve processing and forming machine, including a base shell 1, a stamping head 7 installed on the upper end of the base shell 1, a mold 8 provided in the middle of the upper side of the base shell 1, and a single-chip microcomputer 2 located outside the base shell 1. The input end of the single-chip microcomputer 2 is electrically connected to an external power supply. A top frame 4 is provided on the upper side of the base shell 1 through four evenly distributed support rods 3. A lifting seat 6 is provided in the middle of the top frame 4 through the telescopic end of an electro-hydraulic push rod 5. The input end of the electro-hydraulic push rod 5 is electrically connected to the output end of the single-chip microcomputer 2. The lower middle part of the lifting seat 6 is fixedly connected to the upper side of the stamping head 7. The corners of the lifting seat 6 are slidably connected to the adjacent support rods 3 through through holes. A laser sensor 10 is provided on the upper right end of the lifting seat 6. The laser sensor 10 is bidirectionally electrically connected to the single-chip microcomputer 2. When using the device to process and form the wear-resistant hydraulic cylinder guide sleeve... First, the high-temperature hydraulic cylinder guide sleeve material is loaded into the mold cavity of mold 8. Then, the microcontroller 2 starts the electro-hydraulic push rod 5, causing its extension end to drive the lifting seat 6 to slide vertically down along the support rod 3. The lifting seat 6 drives the stamping head 7 to move down to stamp the high-temperature hydraulic cylinder guide sleeve material in mold 8. During this process, the microcontroller 2 starts the laser sensor 10. The laser sensor 10 emits a light signal to irradiate the bottom wall of the top frame 4 and reflects it back to the initial position. The laser sensor 10 obtains the vertical movement distance of the stamping head 7 based on the propagation time and speed of the light signal. Then, the laser sensor 10 transmits the detection result to the microcontroller 2 in the form of an electrical signal. The microcontroller 2 then uses the extension end of the electro-hydraulic push rod 5 to extend and stop according to the measured result, thereby indirectly and more accurately controlling the vertical movement distance of the stamping head 7, which facilitates the stamping and forming operation of the hydraulic cylinder guide sleeve. It also includes a feeding mechanism 9.

[0022] The unloading mechanism 9 includes an ejector seat 91, a vertical slide rod 92, a foot pedal linkage assembly 93, and a reset assembly 94. The ejector seat 91 is slidably connected to the mold cavity of the mold 8. The lower side of the ejector seat 91 is provided with a vertical slide rod 92. The lower end of the vertical slide rod 92 passes through a circular hole opened in the middle of the mold 8 and the bottom shell 1. The foot pedal linkage assembly 93 is provided between the bottom shell 1 and the vertical slide rod 92. The reset assembly 94 is provided between the foot pedal linkage assembly 93 and the bottom shell 1. The foot pedal linkage assembly 93 includes a U-shaped seat 931, a rotating shaft 932, a connecting rod 933, a U-shaped seat 934, a rotating shaft 935, a connecting rod 936, a foot pedal 937, and a clearance groove 938. The U-shaped seat 931 is set on the bottom wall of the bottom shell 1. The interior of the U-shaped seat 931 is connected to the rotating shaft 94. 932 is rotatably connected to a connecting rod 933. A U-shaped seat 934 is provided on the lower side of the vertical slide rod 92. The interior of the U-shaped seat 934 and the right end of the connecting rod 933 are rotatably connected to a rotating shaft 935 via a bearing. A connecting rod 936 is provided between the two rotating shafts 935. A clearance groove 938 is provided at the lower end of the front wall of the bottom shell 1. The front end of the connecting rod 933 passes through the clearance groove 938 and is provided with a foot pedal 937. The reset assembly 94 includes a tension spring 941 and a spring 942. The spring 942 is located between the top wall of the bottom shell 1 and the upper surface of the U-shaped seat 934. The spring 942 is movably sleeved on the outside of the vertical slide rod 92. A tension spring 941 is provided between the lower right end of the connecting rod 933 and the bottom wall of the bottom shell 1. The feeding mechanism 9 also includes a dovetail groove. 95 and movable guard 96, dovetail groove 95 is opened at the lower front end of the bottom shell 1, movable guard 96 is slidably connected inside the dovetail groove 95, movable guard 96 is installed in conjunction with foot pedal 937, after the hydraulic cylinder guide sleeve is stamped, the single-chip microcomputer 2 controls the electro-hydraulic push rod 5 to make the lifting seat 6 drive the stamping head 7 to move up and reset, then the operator steps on foot pedal 937 with his right foot, foot pedal 937 drives the front end of connecting rod 1 933 to rotate downward around the axis of rotating shaft 1 932 (moving and avoiding the movement of the front end of connecting rod 1 933 by the avoidance groove 938 opened on the bottom shell 1), during the process of the rear end of connecting rod 1 933 rotating upward around the axis of rotating shaft 1 932, the lever principle is used to make the U-shaped seat 2 through rotating shaft 2 935 and connecting rod 2 936. 934 drives the vertical slide bar 92 to move vertically upward along the circular hole. The upper end of the vertical slide bar 92 drives the ejector seat 91 to move vertically upward along the inner wall of the mold cavity. In turn, the ejector seat 91 pushes the forming cylinder guide sleeve in the mold cavity upward and ejects it. During this process, the upper and lower ends of the connecting rod 936 adaptively rotate around the axis of the corresponding rotating shaft 935. The tension spring 941 gradually increases its tension as the rear end of the connecting rod 933 rotates upward around the axis of the rotating shaft 932 (the tension spring 941 itself is always in a stretched state). The spring 942 continuously contracts as the U-shaped seat 934 moves vertically upward (the spring 942 is always in a contracted state), thus facilitating the unloading operation of the forming cylinder guide sleeve in the mold cavity by the operator. After the forming cylinder guide sleeve is unloaded,The worker releases the pressure applied to the foot pedal 937. The U-shaped seat 934, through the compression and reset force of the spring 942, moves the vertical slide rod 92 vertically downwards along the circular hole to reset. The rear end of the connecting rod 933, through the tension and reset force of the tension spring 941, flips downwards around the axis of the rotating shaft 932 to reset, thus restoring the feeding components inside the device to their initial state, preparing for the next feeding of the molded hydraulic cylinder guide sleeve. The worker then slides the movable cover 96 to the right along the dovetail groove 95, causing the movable cover 96 to cover the upper end of the foot pedal 937, preventing accidental activation. This device, through the worker's foot pressure and lever principle, automatically ejects the initially molded wear-resistant hydraulic cylinder guide sleeve from the corresponding mold via transmission elements. Furthermore, each component can automatically reset later through elastic elements, allowing the worker to adjust the clamping points using pliers according to the weight distribution of the wear-resistant hydraulic cylinder guide sleeve, thus facilitating the feeding operation of the initially molded wear-resistant hydraulic cylinder guide sleeve.

[0023] The working principle of the wear-resistant hydraulic cylinder guide sleeve processing and forming machine provided by this utility model is as follows: When using the device to process and form the wear-resistant hydraulic cylinder guide sleeve, firstly, the high-temperature cylinder guide sleeve raw material is loaded into the mold cavity of the mold 8. Then, the microcontroller 2 starts the electro-hydraulic push rod 5, causing its extension end to drive the lifting seat 6 to slide vertically down along the support rod 3. The lifting seat 6 drives the stamping head 7 to move down to stamp and form the high-temperature cylinder guide sleeve raw material in the mold 8. During this process, the microcontroller 2 starts the laser sensor 10. The laser sensor 10 emits a light signal to irradiate the bottom wall of the top frame 4 and reflects it back to the initial position. The laser sensor 10 obtains the vertical movement distance of the stamping head 7 based on the propagation time and speed of the light signal. Then, the laser sensor 10... The detection result is transmitted to the microcontroller 2 as an electrical signal. The microcontroller 2 then controls the extension and retraction of the electro-hydraulic actuator 5 based on the measured result, thereby indirectly and precisely controlling the vertical movement distance of the stamping head 7. This facilitates the stamping process of the hydraulic cylinder guide sleeve. After the hydraulic cylinder guide sleeve is stamped, the microcontroller 2 controls the electro-hydraulic actuator 5 to cause the lifting seat 6 to move the stamping head 7 upwards and reset. Then, the operator steps on the foot pedal 937 with their right foot. The foot pedal 937 causes the front end of the connecting rod 933 to rotate downwards around the axis of the rotating shaft 932 (the movement of the front end of the connecting rod 933 is avoided by the clearance groove 938 on the bottom shell 1). During the upward rotation of the rear end of the connecting rod 933 around the axis of the rotating shaft 932... Utilizing the lever principle, the U-shaped seat 934 drives the vertical slide bar 92 to move vertically upward along the circular hole via the second rotating shaft 935 and the second connecting rod 936. The upper end of the vertical slide bar 92 drives the ejector seat 91 to move vertically upward along the inner wall of the mold cavity. The ejector seat 91 then pushes the forming cylinder guide sleeve upward through the mold cavity. During this process, both the upper and lower ends of the second connecting rod 936 adaptively rotate around the corresponding axis of the second rotating shaft 935. The tension spring 941 gradually increases its tension as the rear end of the first connecting rod 933 rotates upward around the axis of the first rotating shaft 932 (the tension spring 941 itself is always in a stretched state). The spring 942 continuously contracts as the U-shaped seat 934 moves vertically upward (the spring 942 is always in a contracted state), thus facilitating operation. The operator performs the unloading operation of the molding cylinder guide sleeve in the mold cavity. After the molding cylinder guide sleeve is unloaded, the operator releases the stepping force applied to the foot pedal 937. The U-shaped seat 934, through the compression and reset force of the spring 942, drives the vertical slide rod 92 to move vertically downward along the round hole to reset. The rear end of the connecting rod 933, through the tension and reset force of the tension spring 941, flips downward around the axis of the rotating shaft 932 to reset, thereby restoring the unloading component in the device to its initial state, preparing for the next unloading of the molding cylinder guide sleeve. Then, the operator slides the movable cover 96 to the right along the dovetail groove 95 with his foot, so that the movable cover 96 covers the upper end of the foot pedal 937 to prevent the foot pedal 937 from being accidentally touched.

[0024] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an MCS-51, the electro-hydraulic actuator 5 can be a DYTZB1000-500, and the laser sensor 10 can be a WH-LRF laser rangefinder. The microcontroller 2 controls the operation of the electro-hydraulic actuator 5 and the laser sensor 10 using methods commonly used in the prior art.
