Description

Technical Field

[0001] This utility model relates to the field of water pump manufacturing, and specifically to an automated device for bending water pump pull-up fasteners. Background Technology

[0002] As an important component of water pumps, the water pump pull-out assembly has high requirements for shape and dimensional accuracy.

[0003] Currently, the bent parts of the snap fastener assembly need to be manually placed into the fixture, and only one part can be produced after one part is placed, which results in low production efficiency.

[0004] In addition, the positioning of the zipper assembly often relies on manual operation, which not only increases the difficulty of operation, but also makes it difficult to guarantee the accuracy of positioning, resulting in inconsistent quality of parts and insufficient positioning accuracy during the production process.

[0005] Moreover, the existing working environment is not clean enough, the existing equipment is too low, and the operators need to sit on low stools and bend over to operate it. Working for a long time can easily lead to fatigue, and the equipment lacks protective devices. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automated device for bending water pump pull-out components. By using automated equipment and bending molds for manufacturing, it can ensure that the bending angle and shape of the components meet the design requirements, while improving production efficiency and product quality, reducing labor intensity, and improving the working environment.

[0007] The objective of this utility model is achieved through the following technical solution: an automated device for bending a water pump pull buckle assembly, wherein the water pump pull buckle assembly includes a pull strap and a buckle body, and the device includes:

[0008] The frame has a platform for loading the water pump pull-out assembly, and a discharge port is opened on one side of the frame for unloading the water pump pull-out assembly.

[0009] The cylinder is fixed to the frame by a cylinder mounting plate, and the piston rod of the cylinder is used to connect and drive the pressure rod.

[0010] A rotary disk assembly is mounted on a frame below the cylinder and faces the placement platform. Several workstations are evenly arranged along the circumference of the rotary disk assembly, and a forming mold is set at each workstation. The water pump pull-out assembly is pre-placed and positioned on the forming mold. When the rotary disk assembly rotates, the forming molds at each workstation pass under the pressure rod one by one. The water pump pull-out assembly is pressed and formed by the cooperation between the pressure rod and the forming mold.

[0011] A feeding mechanism, mounted on a frame between the rotary table assembly and the discharge port, is used to grip the water pump pull-out assembly press-formed on the molding die and convey it to the discharge port to complete the feeding process; and

[0012] The touch screen system is fixed on the cylinder mounting plate and is used to electrically connect to the electrical control box. The electrical control box is mounted on the frame below the rotary table assembly and is electrically connected to the cylinder, the rotary table assembly and the feeding mechanism to achieve control.

[0013] As a further technical solution, the rotary disk assembly includes a turntable disposed below the cylinder, and a cam divider disposed below the turntable for driving the turntable to rotate. A cam disk is mounted on the output shaft of the cam divider, and a photoelectric switch is disposed directly opposite the cam disk. When the input shaft of the cam divider rotates one revolution, the cam disk rotates one revolution synchronously. At this time, the photoelectric switch is triggered and sends a signal to the electrical control box to control the cam divider to stop running. At the same time, the cylinder presses down and the pressure rod presses the part into the forming mold for forming.

[0014] As a further technical solution, the turntable is sequentially equipped with four workstations: a part forming position, a waiting position, a loading operation position, and a waiting bending position. The part forming position is located directly below the cylinder's pressure rod, where the water pump pull-up assembly is press-fitted and formed. The waiting position is located directly below the unloading mechanism, where the unloading mechanism clamps the water pump pull-up assembly from the waiting position and unloads it from the discharge port. The loading operation position faces the placement platform, where the operator loads the material.

[0015] As a further technical solution, the forming mold includes a mold base fixed on a turntable. A groove is opened in the center of the mold base for inserting two symmetrical clamping blocks, so that the sidewalls of the clamping blocks rest against the groove. The mold base and the corresponding clamping blocks are connected by a tension spring, so that the mold base and the clamping blocks are kept in a constant fit. A positioning pin hole is opened at the bottom of the groove for installing a positioning pin. Fixing holes are opened at the bottom of the groove on both sides of the positioning pin hole for installing shoulder bolts. After the shoulder bolts are fitted with compression springs, they are connected to the bottom of the bending mold, so that the bottom surface of the bending mold contacts the clamping blocks. At the same time, the bending mold is inserted into the openings of the two clamping blocks. The positioning pin passes through the two clamping blocks and then through the bending mold, and extends out from the top of the bending mold to cooperate with the center hole B opened on the buckle body to position the water pump buckle assembly.

[0016] As a further technical solution, a U-shaped groove is provided on the bending mold, and a forming groove is provided in the center of the U-shaped groove for the water pump pull buckle assembly to be press-fitted and formed. A center hole A is provided in the center of the forming groove for the positioning pin to pass through. Threaded holes are provided at the bottom of the U-shaped groove on both sides of the forming groove for connecting shoulder bolts.

[0017] As a further technical solution, the upper end of the clamping block has a hook-shaped structure, with a pull strap positioning groove B on the upper end surface. A pull strap positioning groove A is opened at the top of the mold base corresponding to the pull strap positioning groove B. When the side wall of the clamping block rests against the groove, the upper end surface is flush with the top of the mold base, and the pull strap is placed into the pull strap positioning groove A and the pull strap positioning groove B to achieve positioning. A vertical groove is opened at the center of the pressure rod along the vertical direction, and horizontal grooves are opened on both sides of the pressure rod along the horizontal direction. When the water pump pull buckle assembly is pressed into the bending mold, the pull strap is stuck into the vertical groove, thereby reducing the bending angle and realizing material springback compensation. At the same time, the upper end of the clamping block is stuck into the horizontal groove. The clamping block applies pressure to the water pump pull buckle assembly to ensure secondary forming of the material. A cylindrical hole communicating with the vertical groove is opened at the center of the pressure rod for the positioning pin to pass through.

[0018] As a further technical solution, the tension spring is tightened and fixed by screws through screw holes A on the mold base and screw holes B on the clamping block. The distance between screw holes A and B is greater than the center distance of the hook of the tension spring, so that the tension spring is kept in a certain tension state, ensuring that the mold base and the clamping block are kept in a close fit. The bottom contact position of the mold base and the clamping block adopts a rounded corner structure, so that the clamping block can rotate around the axis of the rounded corner structure.

[0019] As a further technical solution, a safety light curtain is installed at the opening on the side of the rack facing the placement platform, and the safety light curtain is electrically connected and communicates with the touch screen system; an oil-water separator is installed on the rack.

[0020] As a further technical solution, guide posts are provided on both sides of the cylinder. The guide posts are slidably guided by guide sleeves that are correspondingly installed on the cylinder mounting plate. The lower end of the guide post is fixed to the cylinder push plate. The piston rod of the cylinder is connected to drive the cylinder push plate through a floating joint. A pressure rod is fixedly connected below the cylinder push plate. The cylinder's downward stroke is adjusted through the cylinder limit sleeve.

[0021] As a further technical solution, the feeding mechanism includes a three-axis cylinder, a slide cylinder, and a guide rod cylinder. The slide cylinder is mounted on the frame via a slide plate. The three-axis cylinder is mounted on the slide of the slide cylinder and slides laterally along the slide cylinder to achieve movement between the forming mold and the discharge port. The guide rod cylinder is connected to the push plate of the three-axis cylinder via a guide rod cylinder mounting plate. The three-axis cylinder drives the guide rod cylinder to move up and down vertically, and the guide rod cylinder clamps the water pump pull-out assembly.

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. An automatic feeding mechanism is designed to ensure that the buckle assembly is fed into the bending station at a constant speed and accurate position, reducing manual intervention and improving production efficiency. The automatic feeding, bending and positioning mechanism reduces manual intervention, speeds up the production process and significantly improves production efficiency. At the same time, the adjustability of the multi-functional bending die allows the equipment to flexibly adapt to buckle assemblies of different specifications and shapes, further improving overall capacity and enhancing the versatility and flexibility of the equipment.

[0024] 2. By using mechanical or photoelectric positioning technology, we ensure that each pull-button assembly is accurately positioned before bending, laying the foundation for precise bending. Through standard mold bending and forming processes, we can ensure that each bending operation meets the design requirements, thereby producing water pump pull-button assemblies with stable and reliable quality.

[0025] 3. The introduction of automated equipment greatly reduces the labor intensity of operators, rather than requiring them to perform heavy physical labor;

[0026] 4. Design an intuitive and easy-to-use control panel and monitoring system (touchscreen system) to facilitate operators in monitoring equipment status, adjusting parameters, and reducing operational difficulty;

[0027] 5. It integrates safety protection measures, such as an emergency stop button and safety light curtains, to ensure the safety of operators. At the same time, the equipment design also takes ergonomic principles into account, allowing operators to work in a more comfortable and healthier environment.

[0028] 6. The equipment is designed with ease of maintenance and upgrades in mind, and its modular design allows for easy disassembly and replacement of various components. Attached Figure Description

[0049] Reference Appendix Figure 15 , 16 The water pump pull buckle assembly includes a pull strap 10 and a buckle body 11, with a center hole B11-1 opened in the center of the buckle body 11.

[0050] like Figure 1 As shown, a placement platform 213 is provided on the frame 21. Operators load the water pump pull-up assembly via the placement platform 213. A discharge port 212 is opened on one side of the frame 21 for unloading the water pump pull-up assembly. A safety light curtain 22 is installed at the opening on the side of the frame 21 facing the placement platform 213. The safety light curtain 22 is electrically connected to the touch screen system 24 for communication, thereby triggering an alarm signal when an operator enters the safe area during equipment operation, controlling the equipment to stop operation to ensure personnel safety. Preferably, an oil-water separator 23 is installed on the frame 21. The oil-water separator 23 can filter moisture and grease from the compressed air entering the equipment from the outside, extending the cylinder's service life.

[0051] Reference Appendix Figure 1 , 27. Cylinder 25 is fixed to frame 21 via cylinder mounting plate 28. The piston rod of cylinder 25 is used to connect and drive pressure rod 1. Further, guide posts 25-1 are provided on both sides of cylinder 25, and two guide sleeves 25-2 are correspondingly provided on cylinder mounting plate 28. The guide posts 25-1 pass through the corresponding guide sleeves 25-2 to achieve sliding guidance. The lower end of the guide post 25-1 is fixedly connected to cylinder push plate 25-4. The piston rod of cylinder 25 is connected to and drives cylinder push plate 25-4 via floating joint 25-3. Pressure rod 1 is fixedly connected below cylinder push plate 25-4. Preferably, the downward stroke of cylinder 25 is adjusted via cylinder limiting sleeve 25-5, which is mounted on cylinder shaft (piston rod).

[0052] like Figure 1 , 4 As shown in Figure 5, the rotary disk assembly 210 is set on the frame 21 below the cylinder 25 and faces the placement platform 213. Several workstations are evenly arranged along the circumferential direction on the rotary disk assembly 210 (four in this embodiment, but other numbers are also possible). Each workstation is equipped with a forming mold 210-3. The water pump pull-out assembly is pre-placed and positioned on the forming mold 210-3. When the rotary disk assembly 210 rotates, the forming mold 210-3 on each workstation passes under the pressure rod 1 one by one. Through the cooperation between the pressure rod 1 and the forming mold 210-3, the water pump pull-out assembly is pressed and formed.

[0053] Furthermore, such as Figure 4 , 5 As shown, the rotary disk assembly 210 includes a turntable 210-2 positioned below the cylinder 25. A cam divider 210-1 is positioned below the turntable 210-2, driving the turntable 210-2 to rotate. A cam disk 210-4 is mounted on the output shaft of the cam divider 210-1, and a photoelectric switch 210-5 is positioned directly opposite the cam disk 210-4. When the input shaft of the cam divider 210-1 rotates one revolution, the cam disk 210-4 rotates one revolution synchronously. At this time, the photoelectric switch 210-5 is triggered and sends a signal to the electrical control box 29, controlling the cam divider 210-1 to stop operating. Simultaneously, the cylinder 25 presses down, and the pressure rod 1 presses the part into the bending mold 5 of the forming mold 210-3 for forming. The cam divider 210-1 is threadedly connected and fixed to the frame 21 via a divider fixing plate 210-6.

[0054] Reference Appendix Figure 1 , 6The turntable 210-2 has four stations arranged sequentially: part forming station I, waiting station II, loading operation station III, and waiting bending station IV, each at a 90° angle to the others. Part forming station I is located directly below the pressure rod 1 of cylinder 25, where the water pump pull-up assembly is press-formed. Waiting station II is located directly below the unloading mechanism 211, which picks up the water pump pull-up assembly from waiting station II and transports it to the discharge port 212 for unloading. Loading operation station III faces (directly opposite) the placement platform 213 for easy loading by the operator. Waiting bending station IV serves as a transfer station, located between part forming station I and loading operation station III. After easy loading, the assembly first enters waiting bending station IV, and then is rotated by turntable 210-2 to part forming station I for press-forming.

[0055] like Figures 8-11 As shown, the molding die 210-3 includes a die base 2 fixed on a turntable 210-2. A groove 2-6 is formed in the center of the die base 2. Two symmetrical clamping blocks 3 are inserted into the groove 2-6. The sidewalls 3-5 of the clamping blocks 3 rest against the groove 2-6, and the die base 2 and the corresponding clamping blocks 3 are connected by a tension spring 6, keeping the die base 2 and the clamping blocks 3 in a constant contact state. Further, as... Figure 13 As shown, a locating pin hole 2-3 is opened at the bottom of the groove 2-6 to fix the locating pin 4. A fixing hole 2-2 is opened at the bottom of the groove 2-6 on both sides of the locating pin hole 2-3. The fixing holes 2-2 are used to install the shoulder bolt 8. After the shoulder bolt 8 is fitted with a compression spring 9, it connects to the bottom of the bending die 5, so that the bottom surface of the bending die 5 contacts the clamping block 3. At the same time, the bending die 5 is inserted into the openings 3-7 of the two clamping blocks 3. The locating pin 4 passes through the two clamping blocks 3 and then through the bending die 5, extending from the top of the bending die 5 (e.g., ...). Figure 8 , 9 As shown), the positioning pin 4 can cooperate with the center hole B11-1 opened on the buckle body 11 to position the water pump buckle assembly.

[0056] Reference Appendix Figure 17 A U-shaped groove 5-4 is opened on the bending mold 5. A forming groove 5-3 is provided in the center of the U-shaped groove 5-4. The water supply pump pull buckle assembly is press-fitted and formed. A center hole A5-1 is opened in the center of the forming groove 5-3 for the positioning pin 4 to pass through. Threaded holes 5-2 are opened at the bottom of the U-shaped grooves 5-4 on both sides of the forming groove 5-3 to connect the shoulder bolt 8.

[0057] like Figure 13 , 14As shown, the upper end 3-6 of the clamping block 3 has a hook-shaped structure. A pull strap positioning groove B3-1 is formed on the surface of the upper end 3-6. A pull strap positioning groove A2-1 is formed on the top of the mold base 2 at the corresponding position of the pull strap positioning groove B3-1. When the side wall 3-5 of the clamping block 3 rests against the groove 2-6, the surface of the upper end 3-6 is flush with the top of the mold base 2 (as shown). Figure 8 , 10 (As shown), the pull strap 10 is positioned by inserting it into the pull strap positioning groove A2-1 and the pull strap positioning groove B3-1. (See attached diagram) Figure 12 A vertical groove 1-1 is formed at the center of the pressure rod 1, and horizontal grooves 1-2 are formed on both sides of the pressure rod 1. When the water pump pull assembly is pressed into the bending die 5, the pull strap 10 is engaged in the vertical groove 1-1, thereby reducing the bending angle and realizing material springback compensation. At the same time, the upper end 3-6 of the clamping block 3 is engaged in the horizontal groove 1-2. The clamping block 3 applies pressure to the water pump pull assembly to ensure secondary forming of the material. A cylindrical hole 1-3 communicating with the vertical groove 1-1 is formed at the center of the pressure rod 1 for the positioning pin 4 to pass through.

[0058] Reference Appendix Figure 10 , 11 13, 14, The tension spring 6 is tightened and fixed by screws 7 through screw holes A2-5 on the mold base 2 and B3-3 on the clamping block 3. Preferably, the distance between screw holes A2-5 and B3-3 is greater than the center distance of the hooks of the tension spring 6, so that the tension spring 6 maintains a certain tension state and ensures that the mold base 2 and the clamping block 3 remain in a close contact state. The bottom contact position between the mold base 2 and the clamping block 3 adopts a rounded corner structure, allowing the clamping block 3 to rotate around the axis of the rounded corner structure. Further, such as Figure 13 As shown, notches 2-4 are provided on both sides of the mold base 2 to facilitate fixing the mold base 2 to the turntable 210-2 with bolts. Figure 14 As shown, the lower end of the clamping block 3 has a clearance hole 3-2 to avoid the compression spring 9 and prevent interference. The clamping block 3 is also provided with a screw hole C3-4 for installing screws 7, which serves to position the clamping block 3 in the mold base 2 and prevent position displacement. At the same time, the screw hole C3-4 is located on the same surface as the screw hole B3-3 and is close to the lower end of the clamping block 3.

[0059] like Figure 1 , 3As shown, the unloading mechanism 211 is mounted on the frame 21 between the rotary disk assembly 210 and the discharge port 212. The unloading mechanism 211 is used to grab the water pump pull-out assembly pressed and formed on the molding die 210-3 and transport it to the discharge port 212 to complete the unloading. Further, the unloading mechanism 211 includes a three-axis cylinder 211-1, a slide cylinder 211-2, and a guide rod cylinder 211-4. The slide cylinder 211-2 is mounted on the frame 21 via a slide plate 211-5. The three-axis cylinder 211-1 is mounted on the slide of the slide cylinder 211-2 and slides laterally along the slide cylinder 211-2 to realize the movement between the molding die 210-3 and the discharge port 212. The guide rod cylinder 211-4 is connected to the push plate of the three-axis cylinder 211-1 via the guide rod cylinder mounting plate 211-3. The three-axis cylinder 211-1 drives the guide rod cylinder 211-4 to move up and down in the vertical direction, and the guide rod cylinder 211-4 is used to clamp the water pump pull-out assembly.

[0060] Reference Appendix Figure 1 , 7 The touch screen system 24 is fixed on the cylinder mounting plate 28. The touch screen system 24 is electrically connected to the electrical control box 29. The electrical control box 29 is installed on the frame 21 below the rotary disk assembly 210. The electrical control box 29 is electrically connected to the cylinder 25, the rotary disk assembly 210 and the feeding mechanism 211 to realize signal control.

[0061] The working process of this utility model:

[0062] During operation, parameters are first set using the touchscreen system 24, and the electrical control box 29 supplies power to the entire system and equipment. The operator loads the water pump pull-tab assembly from the loading operation position III onto the platform 213, positioning the pull strap 10 through the pull strap positioning groove A2-1 and pull strap positioning groove B3-1, and positioning the buckle body 11 through the center hole B11-1 and positioning pin 4. After pre-positioning... Figure 10 As shown, at this time, the pressure rod 1 has not yet been pressed down.

[0063] The cylinder 25 is activated, providing downward pressure for bending and forming the part. Cylinder 25 is mounted on a cylinder mounting plate 28, and a floating joint 25-3 is installed on the cylinder head to compensate for concentricity deviations during vertical movement. The floating joint 25-3 is also connected to a cylinder push plate 25-4. Guide posts 25-1 are installed on both sides of the cylinder push plate 25-4. The guide posts 25-1 cooperate with bearings (guide sleeves 25-2) mounted on the cylinder mounting plate 28 to slide up and down, ensuring the axial accuracy of the cylinder 25's vertical movement. Simultaneously, a pressure rod 1 is installed at the bottom of the cylinder push plate 25-4, pressing the part into the bending die 5 for forming. A cylinder limit sleeve 25-5 is mounted on the cylinder shaft and can be used to adjust the downward stroke of cylinder 25.

[0064] like Figure 6 As shown, the turntable 210-2 is sequentially equipped with four stations: Part Forming Station I, Waiting to Pick Up Station II, Loading Operation Station III, and Waiting to Bending Station IV, each station being 90° apart. Part Forming Station I is located directly below the pressure rod 1 of cylinder 25, where the water pump pull-up assembly is press-fitted. Waiting to Pick Up Station II is located directly below the unloading mechanism 211, which picks up the water pump pull-up assembly from Waiting to Pick Up Station II and transports it to the discharge port 212 for unloading. Loading Operation Station III faces (directly opposite) the placement platform 213, facilitating loading by the operator. Waiting to Bending Station IV serves as a transfer station, located between Part Forming Station I and Loading Operation Station III. After loading, the assembly first enters Waiting to Bending Station IV to wait, and then the turntable 210-2 rotates to Part Forming Station I for press-fitting.

[0065] Furthermore, when the input shaft of the cam divider 210-1 rotates one revolution, the cam disk 210-4 rotates one revolution synchronously. At this time, the photoelectric switch 210-5 is triggered and sends a signal to the electrical control box 29, controlling the cam divider 210-1 to stop operating. Simultaneously, the cylinder 25 presses down, and the pressure rod 1 presses the part into the bending mold 5 of the forming mold 210-3 for forming (the structure of the cam disk 210-4 is determined according to the performance parameters of the selected cam divider 210-1). Under the control of the cam divider 210-1, the turntable 210-2 rotates 90° each time. After each 90° rotation, at the part forming position I, the cylinder 25 controls the pressure rod 1 to press down to complete the pressing and forming of a set of water pump pull-up assembly. After the part completes one bending and forming, the cam divider 210-1 performs the next station change. At this time, the bent and formed part is moved to the waiting position II (near the unloading mechanism 211). At the same time, the three-axis cylinder 211-1 moves down, and the guide rod cylinder 211-4 clamps the bent and formed part. After the three-axis cylinder 211-1 moves up to the designated position, the slide cylinder 211-2 moves to the discharge port 212. After reaching the designated position, the guide rod cylinder 211-4 releases the bent and formed part, and the part falls into the material box.

[0066] At the waiting position II, the unloading mechanism 211 clamps the water pump pull buckle assembly that has been pressed and formed at the previous station and unloads it from the discharge port 212. At the loading operation position III, the operator completes the loading. The waiting bending position IV serves as the waiting station.

[0067] Since the safety light curtain 22 is installed on both sides of the mounting frame 21, it can trigger an alarm signal when personnel enter the safe area while the equipment is running, and the equipment can stop operating to ensure personnel safety.

[0068] It is understood that, for those skilled in the art, any equivalent substitutions or modifications to the technical solutions and inventive concepts of this utility model should fall within the protection scope of the appended claims.
