[0024] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the following will be combined with the appended drawings of the embodiment of the utility model. Figure 1-7 , the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0025] like Figure 1-7 As shown: Example

[0026] A novel shell and tube remover comprises a punch rod 1; a mounting rod 2, wherein the mounting rod 2 is connected to the punch rod 1 and to the tail end of the punch rod 1, and the mounting rod 2 is used to install the remover on an impact device; a positioning head 3, wherein the positioning head 3 is arranged on the top end face of the punch rod 1 and protrudes outward, and the tip position of the positioning head 3 is a conical structure.

[0027] In this embodiment, the shell and tube remover includes a punch rod 1, and a mounting rod 2 is connected to the tail end of the punch rod 1. In the actual manufacturing process, the punch rod 1 and the mounting rod 2 are integrally formed and processed by a lathe. The mounting rod 2 is used to be installed on the hammer head of an electric pick, and the electric pick holds the mounting rod 2. A positioning head 3 is provided on the top end face of the punch rod 1. The positioning head 3 can accurately set the action range of the punch rod 1 at the pipe mouth of the shell tube to prevent deviation from the direction during the impact. The tip of the positioning head 3 is conical in shape. Example

[0028] A positioning platform 6 is arranged on the end surface of the punch rod 1 . The positioning platform 6 is a raised cylindrical platform and protrudes outward with the top surface of the punch rod 1 as a reference.

[0029] Different from the above embodiment, in this embodiment, in order to further prevent the punch from deviating from the tube mouth of the shell tube during the impact process, a positioning platform 6 is provided at the end of the punch rod 1, and the diameter of the positioning platform 6 is smaller than the diameter of the tube mouth. Example

[0030] The positioning head 3 is installed on the outer end surface of the positioning platform 6 and is arranged in the middle position.

[0031] Different from the above-mentioned embodiment, in this embodiment, after the positioning platform 6 is provided, the positioning head 3 is installed on the end surface of the positioning platform 6 and is provided in the middle position. Example

[0032] The punch rod 1 is provided with a retaining ring, which includes an upper retaining ring 4 and a lower retaining ring 5 . The upper retaining ring 4 and the lower retaining ring 5 are spaced apart from each other, and the diameters of the upper retaining ring 4 and the lower retaining ring 5 are both larger than the diameter of the punch rod 1 .

[0033] Different from the above embodiment, in this embodiment, since impurities will be generated between the outer wall of the shell tube and the hole on the positioning plate, it is not easy to pull out the punch rod 1 after entering. Therefore, a retaining ring structure is set on the punch rod 1, including an upper retaining ring 4 and a lower retaining ring 5. The diameters of the upper retaining ring 4 and the lower retaining ring 5 are slightly smaller than the diameter of the pipe mouth. When the punch rod 1 enters the hole on the positioning plate, it is a clearance fit. The space between the upper retaining ring 4 and the lower retaining ring 5 can be used to temporarily store impurities, thereby solving the problem that the punch rod 1 is not easy to pull out. Example

[0034] A reducing column 7 is provided at the lower part of the positioning head 3, and the diameter decreases from the outside to the inside.

[0035] Different from the above-mentioned embodiment, in this embodiment, the lower part of the positioning head 3 can also be configured as a structure of a variable diameter column 7 .

[0036] The working method (or working principle) of the utility model:

[0037] When the present technology is working, firstly install the mounting rod 2 on the electric pick, then align the positioning head 3 with the pipe mouth of the shell tube, and impact the pipe mouth of each shell tube on one side of the positioning plate, that is, the side of the pipe mouth. The working efficiency is high. In this operation, the shell tube on the positioning plate at the other end can be separated by tools, and a sharp object can be used to impact the pipe mouth inward. After separation, the positioning plate on the opposite side can be impacted again by the structure of the present design.

[0038] In the present invention, unless otherwise clearly stipulated and limited, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0039] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
