Description

Technical Field

[0001] The invention relates to the technical field of stamping equipment, in particular to a parts stamping machine for manufacturing automobile engine water pumps. Background Art

[0002] The cylinder block of an automobile engine contains multiple channels for cooling water circulation, connected to the radiator at the front of the vehicle via pipes, forming a large water circulation system. A water pump, driven by a fan belt, pumps hot water out of the engine's cylinder channels and cools it down. Next to the water pump is a thermostat. When the car is first started, it's closed, allowing the cooling water to circulate only within the engine, bypassing the radiator. Once the engine temperature reaches above 95°C, it opens, pumping hot water into the radiator. Cooling air from the vehicle's forward motion blows through the radiator, removing heat. The engine water pump is a crucial component for cooling the engine. Manufacturing automobile engine water pumps is a common process, requiring stamping equipment to produce the blank.

[0003] At present, when the blank is stamped, the opening and closing of the movable die and the fixed die cannot be fully utilized, resulting in a waste of resources.

[0011] Preferably, the movable mold is installed directly below the guide column, so that the movable mold drives the guide column to move, and then the guide column guides the movable mold. There are two hydraulic cylinders, and the two hydraulic cylinders are symmetrically installed along the guide column. The two symmetrical hydraulic cylinders apply driving force to the movable mold together, so that the force on the movable mold is balanced.

[0012] The guide pillars will move together with the movable mold, and the guidance of the guide pillars can make the movable mold move more smoothly and less prone to shaking, reducing the impact of external forces and vibrations, making the overall structure stable.

[0013] Preferably, the pusher assembly includes an elliptical base plate and a through hole, a circular hole is opened at the center of the elliptical base plate, the elliptical base plate is mounted on the outside of the guide post through the circular hole, the through hole is opened inside the movable mold, a pusher rod is fixedly installed at the side of the bottom of the elliptical base plate, the pusher rod and the through hole are on the same vertical line, a first spring is fixedly installed between the elliptical base plate and the movable mold, the guide post passes through the center of the first spring, and as the movable mold moves upward to open the mold, the stamped material parts will be stuck in the inner cavity of the movable mold, and as the top of the elliptical base plate contacts the lower surface of the ceiling, and the movable mold continues to move upward, and under the support of the elliptical base plate, the first spring is compressed, and the bottom end of the pusher rod passes through the through hole. At this time, the bottom end of the pusher rod pushes the material parts stuck at the bottom of the movable mold, so that the material parts are separated from the movable mold, thereby realizing the function of blanking.

[0014] Preferably, the bottom end of the push rod extends to the inside of the through hole, so as to facilitate the use of the through hole to guide the push rod to push downward smoothly for unloading. There are two push rods, and the two push rods are symmetrically installed along the guide column.

[0015] Preferably, there are two diamond-shaped telescopic frames, and the two diamond-shaped telescopic frames are symmetrically installed along the material receiving plate. Using two symmetrical diamond-shaped telescopic frames for support can make the entire mechanism stable, and the diamond-shaped telescopic frames are installed below the ceiling.

[0016] Preferably, the pin passes through the center of the rectangular hole to facilitate limiting the connecting plate so that the connecting plate can move smoothly. The receiving plate is installed at an angle to facilitate the automatic sliding of material parts that fall into the receiving plate.

[0017] Preferably, the pulling assembly includes a rectangular frame and a strip groove, the top of the rectangular frame is fixedly connected to the bending part of the bottom of the diamond-shaped telescopic frame, the strip groove is opened on two sides corresponding to the fixed mold, a connecting rod is slidably installed inside the rectangular frame, a movable extrusion plate is fixedly installed at one end of the connecting rod away from the rectangular frame, a U-shaped rod is fixedly installed at the side outside the movable extrusion plate, and the bottom end of the U-shaped rod extends to the inside of the strip groove.

[0018] Preferably, the rectangular frame is installed directly below the diamond-shaped telescopic frame, so that when the diamond-shaped telescopic frame is extended, the rectangular frame can be driven to move, and the movable extrusion plate is installed on the step surface on the side of the fixed mold, so that the extrusion force can be applied by moving the movable extrusion plate.

[0019] The cam is fixed on the top of the mold, and the cam is fixed on the top of the mold with a plurality of springs, and the cam is fixed on the top of the mold with a plurality of springs.

[0020] Preferably, the outer side of the clamping plate is a curved surface, which can reduce the contact area with the end of the blank, and the clamping plate is adapted to the outer side of the convex slider, which is convenient for limiting the convex slider and facilitating the sliding of the convex slider.

[0021] The movable mold moves downward, and the diamond-shaped telescopic frame is pressed downward, which can cause the diamond-shaped telescopic frame to be compressed and extended. At this time, the rectangular frame is driven to move to the side away from the fixed mold, and then the connecting rod pulls the movable extrusion plate to move. The symmetrical movable extrusion plates on both sides move together, and the ends of the movable extrusion plates are set in a wedge shape, so that the convex-shaped slider is subjected to an inward extrusion force. At this time, the convex-shaped slider drives the arched elastic piece to move inward, and the second spring is compressed;

[0022] As the movable mold moves downward to stamp the blank, the arc surface on the outside of the arched elastic sheet is always in contact with the end of the blank, thereby positioning the blank and preventing it from tilting. As the blank is stamped and formed, the overall length of the material component becomes shorter, and at this time the arc surface on the outside of the arched elastic sheet is separated from the end of the material component.

[0023] The present invention provides a parts stamping machine for manufacturing automobile engine water pumps. It has the following beneficial effects:

[0024] 1. The stamping machine for parts manufactured by the automobile engine water pump uses an oil supply pump to supply oil to the hydraulic cylinder, which makes the hydraulic cylinder work. The extension and contraction of the output end of the hydraulic cylinder can make the movable mold move downward and upward, thereby adjusting the height of the movable mold. The movable mold is placed directly above the fixed mold, which facilitates the cooperation of the movable mold and the fixed mold for stamping work.

[0025] 2. The stamping machine for parts manufactured by the automobile engine water pump will move with the movable mold through the guide pillars. The guide of the guide pillars can make the movable mold move more smoothly and less prone to shaking, reducing the impact of external forces and vibrations, making the overall structure stable.

[0026] 3. In the automobile engine water pump manufacturing parts stamping machine, as the top of the elliptical base plate contacts the lower surface of the ceiling and uses the movable mold to continuously move upward, and under the support of the elliptical base plate, the first spring is compressed, and the bottom end of the pusher rod passes through the through hole. At this time, the bottom end of the pusher rod pushes the material parts stuck at the bottom of the movable mold, so that the material parts are separated from the movable mold, thereby realizing the function of unloading.

[0027] 4. The stamping machine for manufacturing parts of automobile engine water pumps, as the movable mold applies vertical pulling force to the diamond-shaped telescopic frame, the diamond-shaped telescopic frame shrinks and shortens, and then drives the end of the receiving plate toward the bottom of the movable mold through the connecting plate. At this time, the pusher rod is used to push the material parts out and drop them into the receiving plate, and the material is received in time. At this time, the receiving plate transports and exports the material parts.

[0028] 5. The stamping machine for manufacturing parts of automobile engine water pumps uses the two ends of the blank to contact the arc surface of the arched elastic sheet, so that the blank and the arched elastic sheet are in line contact, reducing the contact area, making it easier to stamp and form the blank after it is subjected to the punching pressure, and using two symmetrical arched elastic sheets at both ends of the blank to preliminarily limit the blank, so that the blank is always in the center of the top of the fixed mold.

[0029] 6. The stamping machine for manufacturing parts of automobile engine water pumps can move the rectangular frame by extending the diamond-shaped telescopic frame when the movable mold moves downward to close the mold. At this time, the connecting rod pulls the extrusion plate, thereby causing the convex slider to move inward under the extrusion force. As the movable mold moves downward to stamp the blank, the arc surface on the outside of the arched elastic sheet is always in contact with the end of the blank, thereby positioning the blank and preventing it from skewing. As the blank is stamped and formed, the overall length of the material component becomes shorter, and at this time the arc surface on the outside of the arched elastic sheet is separated from the end of the material component.

[0039] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0040] The first embodiment, as Figure 1-Figure 5 As shown, the present invention provides a technical solution: a parts stamping machine for manufacturing automobile engine water pumps, comprising:

[0041] The frame 1 has a supporting frame body, a ceiling 2 is fixedly installed on the top of the frame 1, and a fixed mold 3 is fixedly installed in the middle of the top of the frame 1;

[0042] A movable die mechanism 4 is used to stamp the blank and is installed on the top of the ceiling 2;

[0043] Among them, the movable mold mechanism 4 includes a hydraulic cylinder 41 and a guide column 42. The hydraulic cylinder 41 is fixedly installed on the step surface at the top of the ceiling 2 through a bracket. A sleeve is fixedly installed in the middle of the step surface at the top of the ceiling 2. The guide column 42 is slidably installed on the step surface at the top of the ceiling 2 through the sleeve. An oil supply pump 43 is fixedly installed on the top of the ceiling 2, and the oil supply pump 43 is installed between them. The output end of the hydraulic cylinder 41 is fixedly installed with a movable mold 44. The movable mold 44 is installed just above the fixed mold 3. The top of the movable mold 44 is in contact with the guide column. The bottom end of 42 is fixedly connected, and a pusher assembly 45 is installed in the middle of the top of the movable mold 44. The staff starts the oil supply pump 43 to work, and uses the oil supply pump 43 to supply oil to the hydraulic cylinder 41, so that the hydraulic cylinder 41 works. The extension and contraction of the output end of the hydraulic cylinder 41 can make the movable mold 44 move downward and upward, thereby adjusting the height of the movable mold 44, and combining the movable mold 44 just above the fixed mold 3, so as to facilitate the cooperation of the movable mold 44 and the fixed mold 3 to perform stamping work;

[0044] The movable mold 44 is installed directly below the guide column 42, so that the movable mold 44 drives the guide column 42 to move, and then the guide column 42 guides the movable mold 44. There are two hydraulic cylinders 41, and the two hydraulic cylinders 41 are symmetrically installed along the guide column 42. The two symmetrical hydraulic cylinders 41 apply driving force to the movable mold 44 together, so that the force on the movable mold 44 is balanced.

[0045] The guide pillars 42 move together with the movable mold 44 , so that the movable mold 44 can move more smoothly under the guidance of the guide pillars 42 .

[0046] The pusher assembly 45 includes an elliptical base plate 451 and a through hole 454. A circular hole is opened at the center of the elliptical base plate 451. The elliptical base plate 451 is mounted on the outside of the guide post 42 through the circular hole. The through hole 454 is opened inside the movable mold 44. A pusher rod 453 is fixedly installed on the side of the bottom of the elliptical base plate 451. The pusher rod 453 and the through hole 454 are on the same vertical line. A first spring 452 is fixedly installed between the elliptical base plate 451 and the movable mold 44. The guide post 42 passes through the center of the first spring 452. When the stamping is completed, As the movable mold 44 moves upward to open the mold, the stamped material parts will be stuck in the inner cavity of the movable mold 44, and as the top of the elliptical substrate 451 contacts the lower surface of the ceiling 2, the movable mold 44 continues to move upward, and under the support of the elliptical substrate 451, the first spring 452 is compressed, and the bottom end of the push rod 453 passes through the through hole 454. At this time, the bottom end of the push rod 453 pushes the material parts stuck at the bottom of the movable mold 44, so that the material parts are separated from the movable mold 44, thereby realizing the function of unloading.

[0047] The bottom end of the push rod 453 extends to the inside of the through hole 454, which facilitates the use of the through hole 454 to guide the push rod 453 to push downward smoothly for unloading. There are two push rods 453, and the two push rods 453 are symmetrically installed along the guide column 42.

[0048] The second embodiment, as Figure 1-Figure 7 As shown, based on the first embodiment:

[0049] The parts stamping machine for automobile engine water pump manufacturing also includes:

[0050] The feeding mechanism 5 is used to receive and output the materials. The feeding mechanism 5 is installed between the fixed mold 3 and the movable mold mechanism 4;

[0051] Among them, the feeding mechanism 5 includes a diamond-shaped telescopic frame 51, which is hingedly installed between the two sides corresponding to the fixed mold 3 and the movable mold mechanism 4. A connecting plate 52 is fixedly installed in the middle of the diamond-shaped telescopic frame 51, and a rectangular hole 53 is opened in the middle of the outer side of the connecting plate 52. A pin 54 is fixedly installed in the middle of the inner side of the diamond-shaped telescopic frame 51, and the pin 54 is slidably installed with the rectangular hole 53. A material receiving plate 55 is fixedly installed on the side of the outer side of the connecting plate 52. A pulling component 56 is installed at the bottom of the diamond-shaped telescopic frame 51. The pulling component 56 is installed near the fixed mold. 3, as the movable mold 44 opens upward, the diamond-shaped telescopic frame 51 is subjected to vertical tension, which causes the diamond-shaped telescopic frame 51 to shrink and shorten. At this time, the connecting plate 52 moves horizontally under the support and limiting action of the pin shaft 54, and then drives the end of the receiving plate 55 to extend toward the bottom of the movable mold 44 through the connecting plate 52. At this time, the push rod 453 is used to push the material parts out and drop them into the receiving plate 55, so that the material is received in time. Combined with the inclined installation of the receiving plate 55, the receiving plate 55 conveys and exports the material parts.

[0052] There are two diamond-shaped telescopic frames 51 , and the two diamond-shaped telescopic frames 51 are symmetrically installed along the material connection plate 55 . Using two symmetrical diamond-shaped telescopic frames 51 for support can make the entire mechanism stable. The diamond-shaped telescopic frames 51 are installed below the ceiling 2 .

[0053] The pin 54 passes through the center of the rectangular hole 53 to facilitate limiting the connection plate 52 so that the connection plate 52 can move smoothly. The receiving plate 55 is installed at an angle to facilitate the automatic sliding of material parts that fall into the receiving plate 55.

[0054] The pulling assembly 56 includes a rectangular frame 561 and a strip groove 562. The top of the rectangular frame 561 is fixedly connected to the bending part of the bottom of the diamond-shaped telescopic frame 51. The strip groove 562 is opened on the two corresponding sides of the fixed mold 3. A connecting rod 563 is slidably installed inside the rectangular frame 561. A movable extrusion plate 564 is fixedly installed at one end of the connecting rod 563 away from the rectangular frame 561. A U-shaped rod 565 is fixedly installed on the side outside the movable extrusion plate 564. The bottom end of the U-shaped rod 565 extends to the inside of the strip groove 562.

[0055] The rectangular frame 561 is installed directly below the diamond-shaped telescopic frame 51, so that when the diamond-shaped telescopic frame 51 is extended, the rectangular frame 561 can be driven to move. The movable extrusion plate 564 is installed on the step surface on the side of the fixed mold 3, so that the extrusion force can be applied by moving the movable extrusion plate 564.

[0056] The third embodiment, as Figure 6-Figure 8 As shown, based on the second embodiment:

[0057] The limiting components 6 are installed on both sides corresponding to the top of the fixed mold 3. The limiting components 6 include a convex slider 61 and a pressing plate 62. A groove is provided on the step surface of the top of the fixed mold 3. The convex slider 61 slides and fits with the fixed mold 3 through the groove. The pressing plate 62 is fixedly installed on the step surface of the top of the fixed mold 3. The pressing plate 62 is installed at a position close to the convex slider 61. An arched elastic sheet 63 is fixedly installed on the side of the outer side of the convex slider 61. A second spring 6 is fixedly installed between the convex slider 61 and the inner cavity of the groove. 4. The staff first places the blank on the top of the fixed mold 3, and uses the symmetrical convex sliders 61 on both sides to support the arched elastic piece 63, so that the two ends of the blank are in contact with the arc surface of the arched elastic piece 63, so that the blank and the arched elastic piece 63 are in line contact, which reduces the contact area and makes it easier to perform stamping after the blank is subjected to the punching pressure. By using two symmetrical arched elastic pieces 63 at both ends of the blank, the blank can be preliminarily limited, so that the blank is always in the central position of the top of the fixed mold 3.

[0058] The outer side of the clamping plate 62 is a curved surface, which can reduce the contact area with the end of the blank, and the clamping plate 62 is adapted to the outer side of the convex slider 61, which is convenient for limiting the convex slider 61 and facilitating the sliding of the convex slider 61.

[0059] As the movable mold 44 moves downward, the diamond-shaped telescopic frame 51 is subjected to downward pressing pressure, which can cause the diamond-shaped telescopic frame 51 to be compressed and extended. At this time, the rectangular frame 561 is driven to move to the side away from the fixed mold 3, and then the connecting pull rod 563 will pull the movable extrusion plate 564 to move. The movable extrusion plates 564 on both sides are symmetrical and move together, and the ends of the movable extrusion plates 564 are set to be wedge-shaped, so that the convex slider 61 is subjected to inward extrusion force. At this time, the convex slider 61 drives the arched elastic piece 63 to move inward, and the second spring 64 is compressed. As the movable mold 44 moves downward to stamp the blank, the arc surface on the outside of the arched elastic piece 63 is always in contact with the end of the blank, thereby positioning the blank, making it less likely to be skewed. After the blank is stamped and formed, the overall length of the material parts becomes shorter. At this time, the arc surface on the outside of the arched elastic piece 63 is separated from the end of the material parts.

[0060] When in use, the staff first places the blank to be stamped on the top of the fixed die 3, and uses the symmetrical convex sliders 61 on both sides to support the arched elastic piece 63, so that the two ends of the blank are in contact with the arc surface of the arched elastic piece 63, so that the blank and the arched elastic piece 63 are in line contact, reducing the contact area, and using the two symmetrical arched elastic pieces 63 at the two ends of the blank, the blank can be initially limited, so that the blank is always in the central position of the top of the fixed die 3;

[0061] At this time, the staff starts the oil supply pump 43 to supply oil to the hydraulic cylinder 41, so that the hydraulic cylinder 41 works. The extension of the output end of the hydraulic cylinder 41 can make the movable mold 44 move downward. When the movable mold 44 moves downward, the diamond-shaped telescopic frame 51 is pressed downward, which can cause the diamond-shaped telescopic frame 51 to be compressed and extended, thereby causing the receiving plate 55 to be driven by the connecting plate 52 to move to the side away from the bottom of the movable mold 44.

[0062] At the same time, the diamond-shaped telescopic frame 51 is compressed and extended, and the rectangular frame 561 is driven to move to the side away from the fixed mold 3, thereby causing the connecting rod 563 to pull the movable extrusion plate 564 to move. The movable extrusion plates 564 on both sides are symmetrically moved together, and the ends of the movable extrusion plates 564 are set as wedge-shaped devices, so that the convex slider 61 is subjected to an inward extrusion force. At this time, the convex slider 61 drives the arched elastic piece 63 to move inward, and the second spring 64 is compressed. When the movable mold 44 moves downward to punch the blank, the arc surface of the outer side of the arched elastic piece 63 is always in contact with the end of the blank, thereby positioning the blank and preventing it from being skewed.

[0063] As the blank is punched and formed, the overall length of the material component becomes shorter, and the arc surface outside the arched elastic piece 63 is separated from the end of the material component;

[0064] When the stamping work is completed, the output end of the hydraulic cylinder 41 is contracted again, which can pull the movable mold 44 upward. At this time, the stamped material parts will be stuck in the inner cavity of the movable mold 44, so that the material parts are driven by the passive mold 44 to move upward. At the same time, as the movable mold 44 opens upward, the diamond telescopic frame 51 is subjected to vertical tension, which makes the diamond telescopic frame 51 shrink and shorten. At this time, the connecting plate 52 moves horizontally under the support and limiting action of the pin shaft 54, and then drives the end of the receiving plate 55 to extend toward the bottom of the movable mold 44 through the connecting plate 52. At this time, the push rod 453 is used to push the material parts out and drop them into the receiving plate 55, so that the material is received in time. Combined with the inclined installation of the receiving plate 55, the receiving plate 55 conveys the material parts to realize automatic unloading.

[0065] The staff can repeat the above actions to carry out batch stamping production.

[0066] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
