Description

Technical Field

[0001] This utility model belongs to the technical field of shearing devices, and particularly relates to an air pump tube shearing device. Background Technology

[0002] Traditional plastic part cutting mainly relies on manual operation of cutting pliers, which results in low cutting efficiency and high labor intensity.

[0003] While existing pneumatic shears can improve efficiency, their air circuit connections often suffer from poor sealing, leading to air pressure loss. Furthermore, the poor positioning accuracy of the plug-in structure affects the shearing stability. Utility Model Content

[0004] This utility model addresses the problems existing in the prior art by proposing the following technical solution:

[0005] A pneumatic pump tubular shearing device includes: a shearing body;

[0006] The shear head is installed at the end of the shearing machine body;

[0007] The tail section of the shearing machine body is connected to the tail section of the shearing machine body;

[0008] A connecting sleeve is fitted onto the outer wall of the rear of the fuselage. The connecting sleeve is connected to an abutment plate via a plugging mechanism. An air pump pipe is fixedly connected to the outside of the abutment plate.

[0009] The outer wall of the tail section of the fuselage is movably fitted with a side plate, and the inner wall of the side plate is fixed with a telescopic rod, the bottom end of which is fixed to the outer wall of the tail section of the fuselage.

[0010] The insertion mechanism includes: an insertion port fixed to the end of the connecting sleeve;

[0011] A insertion groove is formed on the outer wall of the sleeve opening, and the sleeve opening is fixed to the outer wall of the abutment plate;

[0012] The rubber fixing protrusion installed in the plug groove has an arc-shaped end that is inserted into the plug port;

[0013] A flared guide plate symmetrically disposed on the outer wall of the connecting sleeve has an open opening and a length greater than the insertion pipe opening.

[0014] A bolt passes through the guide plate and the socket, with the bottom of the bolt screwed into the outer wall of the socket.

[0015] As a preferred embodiment of the above technical solution, the fixing protrusion is a mushroom-shaped rubber block.

[0016] As a preferred embodiment of the above technical solution, the inner wall of the guide plate abuts against the outer wall of the sleeve opening.

[0017] As a preferred embodiment of the above technical solution, the telescopic rod is a pneumatically driven multi-stage telescopic rod.

[0018] The beneficial effects of this utility model are as follows:

[0019] Improved airtightness: The rubber material of the mushroom-shaped fixing protrusion fills the micro-gap between the connector and the connector groove when under pressure, blocking the gas leakage path; the three-point locking of the bolts ensures that the connection surface is evenly stressed, eliminating sealing failure caused by vibration.

[0020] Optimized operational efficiency: The flared design of the guide plate improves the docking tolerance and shortens the installation time; the travel adjustment range of the telescopic rod reaches ±mm, adapting to the shearing position of different specifications of material heads.

[0021] Enhanced shear stability: Gas circuit sealing ensures improved pressure transmission efficiency and avoids shear interruption caused by gas pressure fluctuations;

[0022] The sliding fit structure between the side plate and the rear of the fuselage absorbs shear recoil force and reduces the vibration amplitude of the equipment. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] like Figure 1 and Figure 2 As shown in this embodiment of the utility model, the tail section 3 of the machine body is quickly and sealed to the air pump pipe 12 via a connecting sleeve 4. The key insertion mechanism's workflow is as follows: Pre-positioning stage: The sleeve port 8 is pushed along the flared opening of the guide plate 9. Since the guide plate 9 is longer than the insertion port 5, the outer wall of the sleeve port 8 first abuts against the inner side of the guide plate 9, completing the rough positioning;

[0029] Precision insertion stage: Continue pushing until the insertion port 5 is inserted into the insertion groove 6. At this time, the arc end of the fixing protrusion 7 is compressed and deformed, and the rubber elasticity is used to tightly adhere to the inner wall of the insertion port 5, forming a double seal. Figure 2 Enlarged structure;

[0030] Locking stage: Tighten bolt 10 so that it passes through guide plate 9 and sleeve port 8 simultaneously and is screwed into threaded hole on outer wall of insertion port 5 to achieve three-point mechanical locking.

[0031] The telescopic rod 14 drives the side plate 13 to move axially along the tail section 3 of the machine body, and the initial position of the shear head 2 is controlled by adjusting the bolts. The air pump pipe 12 is connected to an external air pump pressure gauge. When the air pressure reaches the set threshold, the shear head 2 is triggered to complete the shearing.

[0032] Working principle

[0033] High-pressure gas from the air pump is delivered to the hydraulic chamber at the rear of the machine body 3 via the air pump pipe 12, pushing the piston rod to drive the shear head 2 to complete the shearing action. The pressure gauge monitors the air pressure value in real time. When the pressure reaches 20MPa, the blade of the shear head 2 closes with a response speed of 0.1 seconds. The insertion mechanism remains leak-free under a working pressure of 25MPa. The arc structure of the fixed protrusion 7 reduces the insertion and extraction force by 40%, extending the life of the seal. The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
