Description

Technical Field

[0001] This utility model belongs to the field of cold pump gasket manufacturing technology, and in particular relates to a punching device for cold pump gaskets. Background Technology

[0002] In the manufacturing process of cold pump gaskets, punching is a crucial step. Traditionally, this process has relied on manual operation. Workers manually fix the gasket and use simple tools to punch the gasket to form positioning protrusions. However, this manual punching method has significant limitations and drawbacks. First, manual operation makes it difficult to guarantee consistency in each punching. Due to the instability of human operation and individual differences, significant differences may occur between different batches, and even between products within the same batch, affecting the consistency of product quality and performance. Second, the accuracy of manual punching is also limited, especially when highly precise position control is required. Manual operation struggles to meet the technical standards and is prone to deviations, resulting in inaccurate matching between the gasket and the notch on the second-stage piston ring of the cold pump cylinder, thus affecting the overall operational stability and service life of the equipment. Furthermore, manual operation is inefficient and cannot meet the needs of large-scale production, further limiting the improvement of production capacity.

[0003] In order to solve the above-mentioned technical problems, this utility model designs a punching device for cold pump sealing gaskets. Utility Model Content

[0004] This utility model provides a punching device for cold pump gaskets, aiming to solve the problems of poor operational consistency, low positioning accuracy, and low efficiency in traditional manual punching methods. The technical solution is as follows:

[0005] A punching device for a cold pump gasket includes an upper panel, a lower panel, a sliding rod, and a clamping block. The upper and lower panels are arranged opposite to each other. The bottom of the sliding rod is fixed to the lower panel and slidably connected to the upper panel to realize the up-and-down movement of the upper panel. The lower panel is provided with a positioning hole and a punch. The upper panel is bolted to the positioning block and is provided with a positioning pin. The position of the positioning pin matches the position of the positioning hole. The clamping block is fitted onto the positioning pin, and the edge of the clamping block clamps the gasket with the positioning block.

[0006] Based on the above technical solution, the size of the positioning hole is larger than the size of the positioning pin.

[0007] Based on the above technical solution, an avoidance hole is provided on the positioning block.

[0008] Preferably, the upper panel includes an upper aluminum alloy plate and an upper acrylic plate, which are connected by bolts.

[0009] Beneficial effects

[0010] Compared with existing technologies, the beneficial effects of this utility model are: 1. Improved punching consistency: The design of positioning holes and positioning pins ensures the consistency and accuracy of punching positions each time, avoiding individual differences and instability caused by manual operation. 2. Increased production efficiency: The semi-automated operation process, especially the automatic reset function achieved by using elastic elements, significantly reduces the need for manual intervention, improves production efficiency, and is suitable for large-scale production needs.

[0023] like Figure 1 As shown, a punching device for a cold pump gasket includes an upper panel 1, a lower panel 2, a sliding rod 3, and a clamping block 5.

[0024] The upper panel 1 and lower panel 2 are arranged opposite to each other. The bottom of the sliding rod 3 is fixed to the lower panel 2, and the sliding rod 3 is slidably connected to the upper panel 1 to realize the up and down movement of the upper panel 1. The design of the sliding rod 3 being fixed to the lower panel 2 at the bottom and slidably connected to the upper panel 1 allows the operator to adjust the pressure and depth applied by the punch 7 to the sealing gasket 9 by controlling the up and down movement of the upper panel 1.

[0025] like Figure 2 As shown, the upper panel 1 includes an upper aluminum alloy plate 11 and an upper acrylic plate 12, which are connected by bolts. The lower panel 2 includes a lower aluminum alloy plate 21 and a lower acrylic plate 22, which are connected by bolts.

[0026] The upper aluminum alloy plate 11 and lower aluminum alloy plate 21 provide high strength and good rigidity, ensuring that the entire device can withstand sufficient pressure without deformation during use, which is crucial for maintaining the accuracy and consistency of the punching operation. The upper acrylic plate 12 and lower acrylic plate 22 are lighter and have good transparency. This material choice not only reduces the weight of the entire device, making it easier to handle and operate, but also provides convenience for observing the internal working conditions if necessary.

[0027] like Figure 3As shown, the lower panel 2 has a positioning hole 4, and the upper panel 1 has a positioning pin 6. The position of the positioning pin 6 matches the position of the positioning hole 4, and the size of the positioning hole 4 is larger than the size of the positioning pin 6. By precisely inserting the positioning pin 6 into the positioning hole 4, it can be ensured that the relative positions between the upper panel 1 and the lower panel 2 remain consistent during operation.

[0028] In practice, perfectly precise manual alignment can be difficult, especially when frequent gasket changes are required or high-speed production is involved. The locating pin 6 and locating hole 4 effectively position the upper panel 1 and lower panel 2, ensuring the accuracy of subsequent punching.

[0029] A punch 7 is provided on the lower panel 2, and the punch 7 and the lower panel 2 are interference-fitted. The interference fit ensures that the punch 7 is firmly fixed on the lower panel 2, reducing the risk of loosening or displacement caused by vibration or impact during operation.

[0030] like Figure 4 As shown, the upper panel 1 is bolted to the positioning block 8. This bolted connection not only facilitates installation and disassembly but also allows for adjustment of the positioning block 8's position to accommodate sealing gaskets of different sizes or shapes. The positioning block 8 is circular, but different shapes can also be used as needed.

[0031] like Figure 5 As shown, the clamping block 5 is fitted onto the positioning pin 6, and the edge of the clamping block 5 clamps the sealing gasket 9 with the positioning block 8. This design ensures that the sealing gasket will not shift or deviate during the punching process.

[0032] The locating pin 6 is mounted on the upper panel 1, and its position matches the locating hole 4 on the lower panel 2. During punching operations, inserting the locating pin 6 into the locating hole 4 ensures precise alignment between the upper panel 1 and the lower panel 2, thereby guaranteeing that the punch 7 can accurately form protrusions on the sealing gasket 9. The locating pin 6 also provides a stable support base for the clamping block 5. The clamping block 5 is fitted onto the locating pin 6, which determines the position of the clamping block 5 and limits its range of motion, ensuring that the clamping block 5 can stably and accurately engage with the locating block 8 to clamp the sealing gasket 9.

[0033] The positioning block 8 has a clearance hole 81. The clearance hole 81 prevents collision with the punch 7. During the punching operation, the punch 7 needs to act on the sealing gasket 9 to form a protrusion. If the positioning block 8 does not have a clearance hole 81, the punch 7 may collide with or be obstructed by the positioning block 8. By providing the clearance hole 81, it can be ensured that the punch 7 can complete the punching process smoothly without any physical obstruction.

[0034] After the punching is completed, manually lifting the upper panel 1 would increase the complexity of the operation. To make the entire operation process smoother and more efficient, an elastic element is also provided between the upper panel 1 and the lower panel 2. This elastic element can automatically return to its original state after the upper panel 1 is pressed down.

[0035] Specifically, a spring is fitted onto the sliding rod 3 near the end of the upper panel 1. When the upper panel 1 is pressed down by an external force, the spring is compressed. When the external force is removed, the spring's restoring force automatically pushes the upper panel 1 back to its initial position. This eliminates the need for operators to manually lift the upper panel 1, simplifying the operation and improving work efficiency.

[0036] The number of sliding rods 3 is two. The design of two sliding rods 3 provides a more stable support structure, ensuring the stability and verticality of the upper panel 1 during up and down movement, thereby ensuring that the position of the impact point is accurate and consistent each time.

[0037] In the manufacturing and maintenance of cold pumps (such as pumps used in refrigeration equipment and low-temperature scientific experimental equipment), the gasket is one of the key components. To ensure that the gasket can be installed correctly and to prevent it from rotating or shifting during use, a raised dot is usually punched into the gasket. This raised dot corresponds to the notch on the piston expansion ring of the second stage of the cold pump cylinder, thus ensuring that the gasket is fixed in position after installation.

[0038] In use, connect the positioning block 8 to the top plate 1 with bolts. Note that the clearance hole 81 on the positioning block 8 should correspond to the position of the punch 7, so that the punch 7 can act on the sealing gasket 9 without obstruction during subsequent operations. Place the sealing gasket 9 onto the positioning block 8. Ensure that the sealing gasket 9 is placed stably and correctly, preparing for subsequent clamping.

[0039] Fit the clamping block 5 onto the positioning pin 6, and make the edge of the clamping block 5 work together with the positioning block 8 to make close contact with the sealing gasket 9, ensuring that the sealing gasket 9 is firmly clamped.

[0040] By applying downward force manually or mechanically, the upper panel 1 slides down along the sliding rod 3, gradually approaching the lower panel 2. During this process, as the upper panel 1 descends, the punch 7 contacts and acts on the sealing gasket 9, forming a protrusion on the sealing gasket 9.

[0041] At this point, the positioning pin 6 on the upper panel 1 is inserted into the positioning hole 4 on the lower panel 2. This ensures accurate alignment of the upper and lower panels.

[0042] After the punch point is completed, remove the external force. If an elastic element is set, its elasticity will automatically restore the upper panel 1 to the initial position; otherwise, manually lift the upper panel 1.

[0043] Loosen the clamping block 5, remove the stamped sealing gasket 9 from the positioning block 8, and check whether the stamping quality meets the requirements.

[0044] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
