DETAILED DESCRIPTION

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

[0029] Embodiment one

[0030] Reference Figures 1-4 An extrusion tool, comprising:

[0031] The first card frame 1 and the second card frame 2 are main clamping components, and the first card frame 1 and the second card frame 2 are opened and closed through the hinge at the top. One side of each card frame is provided with a placing groove 7 for placing the extrusion tool bit 8. The extrusion tool bit 8 is designed to be detachable, so as to be replaced to adapt to different sizes or types of railway glued insulation joint clamps.

[0032] Two plug-in holes 16 are symmetrically arranged on the two sides of the connecting frame 14, which are used to be connected with extrusion equipment (such as a hydraulic machine or a mechanical arm) to realize force transmission and amplification.

[0033] The limiting assembly includes two limiting grooves 3 arranged on one side of the first card frame 1 and the second card frame 2. A crossbar 4 is rotatably arranged in the limiting groove 3 of the first card frame 1. One end of the crossbar 4 is fixed with a limiting block 5. By clamping the crossbar 4 into the limiting groove 3 of the second card frame 2, the position of the first card frame 1 and the second card frame 2 is limited, so that the relative position of the first card frame 1 and the second card frame 2 on the rail is stable, which ensures that the extrusion tool bit 8 can accurately align and abut against the two sides of the railway glued insulation joint clamp, improves the disassembly precision and effect, reduces the risk of incomplete disassembly or damage to the clamp due to position deviation, and at the same time, enhances the overall structural strength of the first card frame 1 and the second card frame 2, so that it can withstand greater extrusion force, ensuring the smooth progress of the disassembly work. The outer part of the crossbar 4 is sleeved with a roller 6. The design of the roller 6 helps to reduce friction and facilitate movement, so that the overall movement of the tool is more smooth.

[0034] In order to firmly lock the first card frame 1 and the second card frame 2, a locking assembly is designed between the first card frame 1 and the second card frame 2. The locking assembly includes two through holes 10 arranged on one side of each card frame. A same bolt rod 11 passes through the two through holes 10, and a nut knob 12 is threadedly connected to one end of the bolt rod 11 to realize locking. This prevents the first card frame 1 and the second card frame 2 from suddenly opening due to vibration or impact during disassembly, which ensures the safety of the operator and the equipment, enhances the overall stability of the entire disassembly tool system, and enables it to more effectively transmit extrusion force to achieve smooth disassembly of the railway glued insulation joint clamp.

[0035] The inner walls of the first card frame 1 and the second card frame 2 are fixed with springs 18, and the other ends of the springs 18 are fixed with gaskets 19. A sleeve 20 is fixed between the two gaskets 19. The bolt rod 11 is detachably arranged in the sleeve 20. When the tool is taken out, the springs 18 on the inner sides of the first card frame 1 and the second card frame 2 push the first card frame 1 and the second card frame 2 to open, so that the openings at the bottoms of the first card frame 1 and the second card frame 2 are enlarged. When the first card frame 1 and the second card frame 2 are installed, the bottom openings can be easily enlarged to adapt to the rail, which simplifies the operation process, improves the work efficiency, and enhances the adaptability and flexibility of the tool.

[0036] The application can be applied to the technical field of disassembling extrusion tools of railway bonded insulation joint clamps, and can also be applied to other fields of the application.

[0039] In order to facilitate the connection and disassembly of the connecting frame 14 and the first clamping frame 1 and the second clamping frame 2, the rear sides of both are provided with plug-in blocks 13 and corresponding plug-in slots 15, the plug-in blocks 13 and the plug-in slots 15 are matched, and plug-in fixing can be easily realized.

[0040] In order to facilitate carrying and operation, the top of the first clamping frame 1 and the connecting frame 14 are both fixed with handles 17.
