Description

Technical Field

[0001] This utility model relates to the field of valve core processing technology, and in particular to a valve core step-by-step core extraction mechanism. Background Technology

[0002] The valve core is a valve component that enables the valve body to perform basic functions such as directional control, pressure control, or flow control by moving within it.

[0003] After the valve core is initially formed, it needs to be pulled out to ensure that its overall specifications are accurate during use. In the traditional way, in order to prevent damage to the product by forcibly pulling it out, it is pulled out while twisting. However, because the required precision of the pulling force is too high, it is easy to cause the product to get stuck in the pulling process, which affects the twisting process and causes errors.

[0004] Therefore, we provide a valve core step-by-step core pulling mechanism. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a valve core step-by-step core extraction mechanism, thereby achieving the effect of setting the core extraction process as a step-by-step process.

[0006] In view of this, the present invention provides a valve core step-by-step core pulling mechanism, including a processing platform and a core pulling device installed above the processing platform.

[0007] The core-pulling device includes a first coiling mechanism, a second internal pulling mechanism, and a third cutting mechanism.

[0008] The first coilover mechanism includes a first support plate for adjusting support, a central positioning plate for positioning and fastening, and a side support plate for guiding support. The central positioning plate is located between the first support plate and the side support plate, and the first support plate and the central positioning plate move synchronously, while the side support plate and the central positioning plate move with a delay.

[0009] The second internal extraction mechanism includes a side extraction component, which is installed on opposite sides of the processing platform and is inserted into the side of the product.

[0010] The third cutting mechanism includes a cutting positioning block and a cutting cylinder. There are at least two cutting cylinders, and both cutting cylinders are installed on the same side of the cutting positioning block.

[0011] The first coilover mechanism further includes a push cylinder for horizontal drive support, a moving limit block, a connecting rod, and a delay moving rod. The moving limit block is installed at the output end of the push cylinder, the connecting rod is installed at the end of the moving limit block away from the push cylinder, and the delay moving rod is located on one side of the outer end of the connecting rod.

[0012] Preferably, the first support plate has a guide groove for the movable positioning block, the side support plate has a sliding groove for the delayed moving rod to slide a short distance, the delayed moving rod extends to the outside of the side support plate, and one end of the delayed moving rod is installed on the side of the middle positioning plate near the side support plate. The connecting rod is simultaneously inserted into the first support plate and the middle positioning plate.

[0013] Preferably, the first coilover mechanism further includes a rotary motor for coilover rotation support, a drive gear, a long gear, and a driven gear.

[0017] Compared with the prior art, this utility model provides a valve core step-by-step core pulling mechanism, which has the following beneficial effects:

[0018] 1. This utility model uses a first threading mechanism to first thread the molded product, and then moves the first threading mechanism as a whole to form a processing step of threading followed by core pulling. This effectively prevents the product itself from having too many interlocking parts, resulting in excessive clamping force and causing the core pulling process to be slow and prone to jamming by the traditional method of threading and pulling at the same time.

[0019] 2. This utility model sets the distance at which the delay moving rod slides in the groove to be consistent with the distance at the coiling machining position, so that the coiling components can move synchronously, ensuring the accuracy and reliability of the core pulling movement distance.

[0020] 3. With the support and clamping limitation of the first support plate and the middle positioning plate for the rotating part, this utility model ensures the reliability and efficiency of its position during rotation.

[0021] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Example 1: A valve core step-by-step core pulling mechanism, such as Figures 1-4 As shown, it includes a processing platform 1 and a core-pulling device installed on the processing platform 1.

[0031] The core-pulling device includes a first threading mechanism, a second internal pulling mechanism, and a third cutting mechanism.

[0032] The first coilover mechanism includes a first support plate 5 for adjusting support, a middle positioning plate 6 for positioning and fastening, and a side support plate 7 for guiding support. The middle positioning plate 6 is located between the first support plate 5 and the side support plate 7, and the first support plate 5 and the middle positioning plate 6 move synchronously, while the side support plate 7 and the middle positioning plate 6 move with a delay.

[0033] The second internal extraction mechanism includes a side extraction component 13, which is installed on opposite sides of the processing platform 1 and is inserted into the side of the product.

[0034] The third cutting mechanism includes a cutting positioning block 15 and a cutting cylinder 16. There are at least two cutting cylinders 16, and both cutting cylinders 16 are installed on the same side of the cutting positioning block 15.

[0035] First, the first threading mechanism is used to thread the formed product. Then, the first threading mechanism is moved as a whole to move and pull the core of the threaded product. With the combined use of the first support plate 5, the middle positioning plate 6, the side support plate 7 and their internal connecting parts, the device forms a processing step of threading followed by core pulling. This effectively prevents the product itself from having too many intersections, resulting in excessive clamping force. The traditional method of threading and pulling at the same time would lead to a slow core pulling process and easy jamming. Under the pulling stroke of the second inner shaft mechanism, the side of the formed product is pulled. Under the operation of the third cutting mechanism, the formed product is precisely cut, ensuring the accuracy of the cutting. Thus, the device has a step-by-step core pulling processing method, improving the stability and accuracy of the device in pulling the core of the formed product.

[0036] like Figures 1-4 As shown, the first coilover mechanism also includes a push cylinder 2 for horizontal drive support, a moving limit block 3, a connecting rod 4, and a delay moving rod 8. The moving limit block 3 is installed at the output end of the push cylinder 2, the connecting rod 4 is installed at the end of the moving limit block 3 away from the push cylinder 2, and the delay moving rod 8 is located on one side of the outer end of the connecting rod 4.

[0037] The first support plate 5 has a guide groove for moving and positioning the movable limiting block 3. The side support plate 7 has a sliding groove for the short-distance sliding of the delay moving rod 8. The delay moving rod 8 extends to the outside of the side support plate 7, and one end of the delay moving rod 8 is installed on the side of the middle positioning plate 6 near the side support plate 7. The connecting rod 4 is simultaneously inserted into the first support plate 5 and the middle positioning plate 6.

[0038] Driven by the push cylinder 2, connected by the connecting rod 4 and the moving limit block 3, and limited by the movement of the delayed moving rod 8 on the side support plate 7, the push cylinder 2 moves synchronously, causing the moving limit block 3 and the connecting rod 4 to move synchronously. This causes the first support plate 5 and the middle positioning plate 6 to move synchronously with the moving limit block 3 and the connecting rod 4, and the delayed moving rod 8 to move with the middle positioning plate 6. The delayed moving rod 8 slides a certain distance in the groove before driving the side support plate 7 to move. By setting the distance in which the delayed moving rod 8 slides in the groove to be consistent with the distance of the rabbet machining position, the rabbet components can move synchronously, ensuring the accuracy and reliability of the core pulling movement distance.

[0039] like Figures 1-4 As shown, the first coilover mechanism also includes a rotary motor 9 for coilover rotation support, a drive gear 10, a long gear 11, and a driven gear 12. The drive gear 10 is installed at the output end of the rotary motor 9. The long gear 11 is located above the drive gear 10 and is meshed with the drive gear 10. The long gear 11 is meshed with at least two driven gears 12, and the two driven gears 12 are located above the long gear 11 at opposite positions.

[0040] The driving gear 10 is rotatably mounted below the first support plate 5, the long gear 11 is rotatably mounted on the lower half of the first support plate 5, and the two driven gears 12 are rotatably mounted between the middle positioning plate 6 and the side support plate 7.

[0041] Firstly, based on the meshing of the driving gear 10, the long gear 11, and the driven gear 12, the rotation of the rotating motor 9 is transmitted to the swivel position and driven to rotate, performing swivel processing on the product. Under the support of the horizontal movement of the push cylinder 2, the swivel processing part moves horizontally after rotation, improving the accuracy and efficiency of the swivel processing. With the support and clamping limit of the rotating part by the first support plate 5 and the middle positioning plate 6, the reliability and efficiency of its position during rotation are ensured.

[0042] Example 2: A valve core step-by-step core pulling mechanism, such as Figures 1-4 As shown, the second inner pull mechanism also includes a fastening block 14 with a certain elastic support. There are several fastening blocks 14, and the side pull assembly 13 is inserted into the side port of the product through the fastening blocks 14.

[0043] By setting the fastening block 14 to a structure with a certain elastic tension, it is pushed to the side of the product by the side extraction component 13. After the side extraction component 13 is gradually inserted into the product, the tension and size of the fastening block 14 itself gradually increase, so as to expand and limit the fastening of the side end, ensuring the tightness of the connection when pulling out the core.

[0044] like Figures 1-4As shown, the third cutting mechanism also includes a cutting cylinder 16 supported by a slow-moving drive, and the cutting cylinder 16 contains symmetrically distributed annular cutters.

[0045] By setting the rotation drive of the cutting cylinder 16 to a slow-moving drive and limiting the cutting of the two annular cutters, the precision of the inner thickness cutting of the product is improved, the accuracy of the product after processing is improved, and the accuracy of the device in processing is further improved.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
