This significantly shortens equipment downtime for changeovers, improves production continuity, and effectively increases overall production efficiency.

Description

Technical Field

[0001] This utility model relates to the field of metal stamping technology, and in particular to a ball valve body punching machine. Background Technology

[0002] In the field of ball valve manufacturing, the ball valve body, as the core load-bearing and connecting component of the ball valve, directly determines the sealing performance, service life, and overall assembly quality of the ball valve through its structural integrity and dimensional accuracy. The ball valve body is usually made of metal forging or casting. During the processing, multiple channels of different specifications need to be opened in specific positions, including the main channel hole for medium flow, the valve core hole for installing the valve core, and the bolt hole for assembling flanges or other connecting parts. The processing accuracy of these channels is extremely high, and the key equipment to complete the processing of the above channels is the ball valve body punching machine.

[0003] Among them, the fixture is the core component of the ball valve body punching machine. Its main function is to accurately position and reliably clamp the ball valve body during the punching process, preventing the body from shifting or shaking under the impact force of the punch, thereby ensuring that key dimensions such as punching position, hole diameter and hole perpendicularity meet the design requirements.

[0004] In existing technologies, the fixtures of ball valve body punching machines mostly adopt an integrated structure design, meaning that the positioning cavity of the fixture and the fixture body are an inseparable whole. The shape and size of the cavity are perfectly adapted to a specific specification of ball valve body. However, in the actual ball valve production process, due to the diversification of market demand, there are many specifications and models of ball valves, and the corresponding external dimensions and structural features of the ball valve body also vary greatly. This leads to differences in the local structure of the body (such as the size of the valve core mounting seat). As a result, existing ball valve body punching machines using integrated fixtures must design and manufacture a separate set of fixtures for each specification when facing the processing requirements of different specifications of body. For companies that produce ball valves of multiple specifications, it is often necessary to keep dozens or even hundreds of sets of fixtures of different specifications. This not only occupies a lot of workshop storage space, but also has high design and manufacturing costs, significantly increasing the company's production input. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a ball valve body punching machine. This machine addresses the issue that due to the diversification of market demand and the numerous specifications and models of ball valves, the corresponding dimensions and structural features of the ball valve body also vary significantly, leading to differences in local structures of the body (such as the dimensions of the valve core mounting seat). This means that existing ball valve body punching machines using integrated fixtures must design and manufacture a separate fixture for each specification when processing ball valve bodies of different sizes. For companies producing ball valves of various sizes, this often requires stocking dozens or even hundreds of different fixtures, which not only occupies a large amount of workshop storage space but also results in high design and manufacturing costs, significantly increasing the company's production investment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ball valve body punching machine, comprising a base, a sliding seat, a top plate and a punch, wherein two limiting components are provided on the base;

[0007] The limiting assembly includes a support plate, a first cylinder, a clamping block, and a liner. When the liner is a flat liner, a positioning slider is fixedly installed on the outer wall of the liner. The support plate is fixedly installed on the upper surface of the base. The first cylinder is fixedly installed on the outer wall of the support plate. A positioning slider groove is opened on the outer wall of the clamping block.

[0008] The outer wall of the positioning slider is slidably connected to the inside of the positioning slider groove. The inner wall of the positioning slider groove is provided with a second limiting block groove. A limiting block is slidably connected inside the second limiting block groove. The outer wall of the positioning slider near the limiting block is provided with a first limiting block groove. A push block groove is provided on the upper surface of the clamping block. A push block is slidably connected inside the push block groove. Five return springs are provided inside the second limiting block groove. A limiting block is slidably engaged inside the push block groove. Both limiting components are installed on the upper surface of the base and used in conjunction.

[0009] Preferably, the output end of the first cylinder slides to the outside of the support plate and is fixedly connected to the outer wall of the clamping block.

[0010] Preferably, the outer walls of the two T-shaped blocks on the outer wall of the liner and the outer wall of the clamping block are slidably connected in corresponding slots, and the magnetic block installed on the positioning slider is attracted and positioned by the magnetic seat inside the positioning slider slot.

[0011] Preferably, the end of the limiting block near the first limiting block groove slides into the interior of the positioning slider groove and slides in connection with the interior of the first limiting block groove.

[0012] Preferably, one end of the push block near the limiting block slides into the interior of the second limiting block groove and is fixedly connected to the upper surface of the limiting block, and the two ends of the five reset springs are respectively fixedly connected to the outer wall of the corresponding limiting block and the inner wall of the second limiting block groove.

[0013] Preferably, the two ends of the limiting block are in contact with the inner wall of the corresponding push block groove and the outer wall of the push block, respectively.

[0014] Preferably, the top plate is fixedly installed on the end of the four support columns on the upper surface of the base away from the base, and the four corners of the sliding seat are slidably connected to the outer walls of the four support columns on the upper surface of the base.

[0016] Preferably, when both of the bushings are V-shaped bushings, the two V-shaped bushings are respectively installed on the outer wall of the clamping block.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The ball valve body punching machine uses a push block in the limiting assembly to compress the return spring of the limiting block, thereby releasing the limiting of the liner and allowing the old liner to be removed. Then, the T-shaped block and the positioning slider of the new liner are aligned with the corresponding slot of the clamping block and slid in. After the push block is released, the return spring drives the limiting block to be inserted into the first limiting block slot. Finally, the limiting block is inserted to complete the fixing. This significantly shortens the equipment downtime for changing models, improves production continuity, and effectively improves the overall production efficiency. Attached Figure Description

[0030] Example 1: Reference Figure 1-4 A conventional example of circular body machining (planar liner block 9 + basic limiting block 15)

[0031] Suitable for machining standard circular ball valve bodies, this system achieves stable clamping through a planar liner and a basic limiting structure. The liner uses a planar liner 9, whose flat surface fits against the outer wall of the circular body. The positioning slider 10 is positioned by magnetic attraction and the positioning slider groove 17 of the clamping block 6. The limiting block 15 is engaged in the first limiting block groove 13 under the action of the return spring 14. During punching, the planar liner evenly distributes the clamping force to prevent deformation of the circular body. During disassembly, pushing the push block 8 moves the limiting block out of the groove, and the liner can be easily removed. The operation is simple and suitable for the production and processing of small and medium-sized ball valves.

[0032] Example 2: Reference Figure 5 Example of square / irregular shaped body machining (V-shaped bushing 19 + reinforced return spring)

[0033] For machining irregularly shaped ball valve bodies such as square and hexagonal, a V-shaped liner and a reinforced limiting structure are used to improve clamping compatibility. The liner is replaced with a V-shaped liner 19, whose V-groove fits tightly with the edges of the irregularly shaped ball valve body. The return spring 14 is replaced with a high-strength spring to enhance the clamping force of the limiting block 15. During the machining of the irregularly shaped ball valve body, the V-shaped liner fixes the workpiece by self-locking with the inclined surface. The reinforced spring ensures that the limiting block does not loosen under the vibration of punching, avoiding displacement of the ball valve body and resulting in punching deviation. This method is suitable for machining ball valve bodies with complex shapes.

[0034] Furthermore, when using this device, select the appropriate bushing 9 according to the shape and specifications of the ball valve body to be processed: if the body is a planar contact structure, select a planar bushing; if it is a cylindrical or other arc-shaped surface structure, select a V-shaped bushing 19. When installing the planar bushing, first push the push block 8 outward, causing the limit block 15 to compress the return spring 14 and slide it into the depth of the second limit block groove 16. At this time, align the T-shaped block of the planar bushing with the T-shaped groove of the clamping block 6 and align the positioning slider 10 with the positioning slider groove 17. Slide it along the groove to the fitting position, and the magnetic block on the positioning slider 10 will attract the magnetic seat in the positioning slider groove 17. Positioning is completed, then the push block 8 is released, and the return spring 14 drives the limit block 15 to return to its original position. One end of the limit block 15 slides into the first limit block groove 13 of the positioning slider 10, completing the precise positioning and fixing of the bushing 9. Finally, the limit block 7 is slid into the push block groove 18 to limit the displacement of the push block 8 and ensure the stable installation of the bushing 9. When installing the V-shaped bushing 19, it can be directly fixed to the inner wall of the clamping block 6 of the two sets of limit components with bolts. Then, the ball valve body to be punched is placed between the bushings 9 of the two sets of limit components, and the position of the body is adjusted so that the part to be punched is vertically aligned with the axis of the punch 11, completing the initial positioning. Then, the start-up is completed. The first cylinder 3 is activated, and its output end pushes the clamping block 6 towards the middle body. The clamping blocks 6 of the two sets of limiting components move closer simultaneously, causing the liner 9 to come into close contact with the outer wall of the middle body until the middle body is clamped and fixed. Since the liner 9 and the clamping block 6 are positioned by a T-block, a positioning slider 10, and a limiting block 15, and the first cylinder 3 provides a stable clamping force, it can be ensured that the middle body will not shift or shake during the punching process. Then, the second cylinder 12 is activated, and its output end extends downward, causing the sliding seat 4 to slide vertically downward along the support column. The punch mounted on the lower surface of the sliding seat 4... 11 then moves downwards, applying impact force to the clamped and fixed middle body to be punched, completing the punching process. After punching is completed, the output end of the second cylinder 12 retracts upwards, driving the sliding seat 4 and punch 11 to return to the initial position. Then, the output end of the first cylinder 3 retracts, driving the clamping block 6 and the liner 9 to separate to both sides, releasing the clamping of the middle body. Finally, the operator takes the processed middle body out from between the two sets of limiting components, completing one punching cycle. If different specifications of middle bodies need to be processed, only the corresponding liner 9 needs to be replaced according to the above steps. There is no need to disassemble the entire limiting component, which greatly improves the changeover efficiency.

[0035] By pushing the pusher 8 in the limiting assembly to drive the limiting block 15 to compress the reset spring 14, the old liner can be removed after the limiting of the liner 9 is released. Then, the T-shaped block and the positioning slider 10 of the new liner are aligned with the corresponding slot of the clamping block 6 and slid in. After releasing the pusher 8, the reset spring 14 drives the limiting block 15 to be inserted into the first limiting block slide groove 13. Finally, the limiting card block 7 is inserted to complete the fixing. This greatly shortens the equipment downtime for changing models, improves production continuity, and effectively improves the overall production efficiency.

[0036] Structural Description: Base 1: Base 1 is the foundational load-bearing component of the equipment, made of heavy-duty metal. Its function is to provide a stable support platform for the entire equipment. The upper surface of base 1 not only has two symmetrically distributed limiting components fixedly installed, but also has four rectangularly arranged support columns welded on it. These support columns act as a bridge connecting base 1 and top plate 5, ensuring the structural strength and stability of the equipment frame.

[0037] Support plate 2 and first cylinder 3: Support plate 2 is a vertically arranged metal plate that is fixedly installed on the upper surface of base 1 by bolts. Its function is to provide installation support for first cylinder 3. First cylinder 3 is horizontally fixedly installed on the outer side wall of support plate 2. Its output end passes through the through hole opened on support plate 2 and extends to the inner side, and is fixedly connected to the outer wall of clamping block 6 by bolts. It can drive clamping block 6 to reciprocate linearly in the horizontal direction.

[0038] Clamping block 6: Clamping block 6 is an L-shaped metal block that directly mates with the liner 9. Its outer wall has several fitting structures: First, a positioning slider groove 17, which mates with the positioning slider 10 on the liner 9; second, a T-shaped groove, which slides with two T-shaped blocks on the outer wall of the liner 9 to achieve initial positioning of the liner 9; third, a second limiting block groove 16, which is located on the inner wall of the positioning slider groove 17 and has a limiting block 15 slidably connected inside; fourth, a push block groove 18, which is located on the upper surface of clamping block 6 and has a push block 8 slidably connected inside. The lower end of the push block 8 extends into the second limiting block groove 16 and is fixedly connected to the upper surface of the limiting block 15. The limiting block 15 can be slidably moved by pushing the push block 8; fifth, a limiting block 7 is also slidably engaged in the push block groove 18. The two ends of the limiting block 7 contact the inner wall of the push block groove 18 and the outer wall of the push block 8, respectively, to limit the sliding position of the push block 8.

[0039] Liner 9: Liner 9 is an adapter component that directly contacts the ball valve body. Depending on the shape of the body, it is divided into two types: When liner 9 is a flat liner, a positioning slider 10 is fixedly installed on its outer wall, and a magnetic block is installed on the positioning slider 10. The outer wall of liner 9 also has two T-shaped blocks. When liner 9 is a V-shaped liner 19, the two V-shaped liner blocks 19 are respectively installed on the inner walls of the clamping blocks 6 of the two sets of limiting components, used to adapt to cylindrical or other curved surfaces of the body. The outer wall of the positioning slider 10 of the flat liner slides into the positioning slider groove 17 of the clamping block 6. The T-shaped block and the T-shaped groove of the clamping block 6 are slidably engaged to achieve dual guiding and positioning of the liner 9 and the clamping block 6. The magnetic block on the positioning slider 10 is attracted to the magnetic seat inside the positioning slider groove 17, which further improves the connection stability. In addition, a first limiting block groove 13 is provided on the outer wall of the positioning slider 10 near the limiting block 15. The end of the limiting block 15 near the groove extends into the positioning slider groove 17 and is slidably connected with the first limiting block groove 13. The precise positioning of the liner 9 is achieved through the cooperation of the limiting block 15 and the groove.

[0040] Top plate 5 and sliding seat 4: Top plate 5 is a rectangular metal plate, which is fixedly installed on the top of the four support columns on the upper surface of the base 1 to form the top frame of the equipment. Sliding seat 4 is a horizontally arranged metal seat, with its four corners slidably connected to the outer walls of the four support columns respectively, and can move up and down in a straight line along the support columns. A second cylinder 12 is fixedly installed in the center of the lower surface of top plate 5. The output end of the second cylinder 12 extends vertically downward and is fixedly connected to the upper surface of the sliding seat 4 by bolts. The second cylinder 12 provides power for the up and down movement of the sliding seat 4.

[0041] Punch 11: Punch 11 is a cylindrical metal component made of high-strength wear-resistant steel. It is installed in the center of the lower surface of the sliding seat 4. The axis of punch 11 is vertically aligned with the punching position of the middle body held by the two sets of limiting components. When the sliding seat 4 moves downward, punch 11 can punch the middle body.

[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
