Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ship hull construction, in particular to a marine punching and printing tool. Background Art
[0002] At present, in order to ensure the accuracy of hull manufacturing and assembly during shipbuilding, in addition to marking out various lines in various areas of the hull, it is also necessary to use a hand-held punch to align it with the lines and then use a hand hammer to knock out the punch points distributed in various areas, so as to facilitate subsequent accuracy inspection, construction and acceptance. Therefore, whether it is parts, components, assemblies, sections or sections, they cannot be separated from the punch mark, of course, including the punching of steel plates involving all non-ship products.
[0003] Common hull bottom plates, platform plates, center lines near the hull baseline or non-working surface, rib inspection lines, port 100MK lines, longitudinal section lines, and structure installation reference lines, installation lines, inspection lines, etc., will be surveyed and marked to ensure accuracy, and the foreign punch marks will be knocked and protected to prevent damage in subsequent processes. For the hammering work in the upward area, the operator often has to look up and tilt his head back, that is, aim the hammer at the line and then use a hammer to knock in the opposite direction to make a mark. However, this operation method is prone to the following problems: First, the method of holding the hammer and using the hammer to knock in the opposite direction is affected by the position of the personnel and the working environment. The hammer is prone to slipping or even flying out of the hand, and the hammer is easy to injure the operator. At the same time, the risk of the punch sliding and shifting, causing the person to fall forward, makes the safety of the exposed part of the person's body unable to be guaranteed; second, because the reverse knocking force is small, it cannot meet the depth of the punch mark. The standard punch mark depth is not less than 1.5 to 2 mm, so the clarity and efficiency of the punch mark are not high, affecting subsequent operations; third, reverse knocking is very likely to cause the displacement of the punch and the line, the two cannot completely overlap, and the accuracy is insufficient. Utility Model Content
[0004] The utility model aims to provide a marine punching and printing tool with high safety performance, convenient operation, high precision and strong printing force, which can be suitable for punching and printing work in different directions and different working surfaces, especially for punching and printing work in the supine area.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A marine punching and printing tool, comprising a punch head, a round tube, a round rod and a handle; the inside of the round tube is provided with a central passage matching the round rod; the punch head and the central passage are arranged coaxially, the upper end of the punch head is a pointed end, and the lower end of the punch head is fixedly connected to the upper end of the round tube and blocks the central passage; the round rod is slidably inserted in the central passage, and the upper end of the round rod can be abutted against the lower end of the punch head; the handle is fixedly connected to the lower end of the round rod, and the handle is arranged vertically to the round rod.
[0007] As a preferred solution of the utility model, when the upper end of the round rod abuts against the lower end of the foreign punch, part of the round rod extends out of the round tube and forms a protrusion.
[0008] As a preferred solution of the utility model, a handle is fixedly connected to the outer side of the circular tube.
[0009] As a preferred solution of the present invention, the handle is welded to the round tube.
[0010] As a preferred solution of the utility model, the foreign punch is welded to the round tube.
[0011] As a preferred solution of the present utility model, the round rod is welded to the handle.
[0012] As a preferred solution of the present utility model, the material of the foreign punch, the round tube, the round rod, the handle and the handle are all steel.
[0013] The implementation of the marine punching and printing tool provided by the utility model has the following beneficial effects compared with the prior art:
[0014] 1. When working, the operator inserts the round rod into the central passage of the round tube, then holds the round tube with one hand and the handle with the other hand, and then aligns the tip of the foreign punch with the corresponding marking line on the hull, so that the upper end of the round rod hits the lower end of the foreign punch, so that the tip of the foreign punch leaves a foreign punch point at the position where the marking line needs to be stamped under the impact. It can be suitable for foreign punch stamping work in different directions and different working surfaces. Compared with the method of striking the foreign punch with a hand hammer in the prior art, the stamping force of the foreign punch is greater, which can meet the depth of the foreign punch mark, and the clarity is correspondingly improved, and the labor intensity of the operator can also be reduced.
[0015] 2. For the punching work in the supine area, compared with the existing method of holding the punch and using a hammer to strike in the opposite direction, it can avoid the phenomenon of the hammer injuring the operator, improve the operator's working safety performance, and at the same time, it can also reduce the phenomenon of the punch head deviating from the line, thereby improving accuracy.
[0016] 3. In this tooling, since the foreign punch is coaxially arranged with the central channel, and the handle is arranged vertically with the round rod, in the process of the upper end of the round rod hitting the lower end of the foreign punch, the force can be more concentrated to avoid the deviation of the impact force, thereby further reducing the phenomenon of the foreign punch offset line and ensuring the smooth progress of subsequent operations.

[0023] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0024] In the description of the present utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. It should be understood that the terms "first", "second", etc. are used in the present utility model to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present utility model, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.
[0025] like Figures 1 to 3As shown, the preferred embodiment of the utility model provides a marine foreign punching and printing tool, which includes a foreign punch 1, a round tube 2, a round rod 3 and a handle 4, the interior of the round tube 2 is provided with a central passage 21 matching the round rod 3; the foreign punch 1 is coaxially arranged with the central passage 21, the upper end of the foreign punch 1 is a pointed end, and the lower end of the foreign punch 1 is fixedly connected to the round tube 2 and blocks the upper end of the central passage 21; the round rod 3 can be slidably inserted in the central passage 21, and the upper end of the round rod 3 can be against the lower end of the foreign punch 1; the handle 4 is fixedly connected to the lower end of the round rod 3, and the handle 4 is arranged vertically to the round rod 3.
[0026] According to the marine punching and stamping tool of the utility model, when working, the operator inserts the round rod 3 into the central passage 21 of the round tube 2, then holds the round tube 2 with one hand and the handle 4 with the other hand, then aligns the tip of the punch head 1 with the corresponding marking line on the hull, so that the upper end of the round rod 3 hits the lower end of the punch head 1, so that the tip of the punch head 1 leaves a punch point at the position where the marking line needs to be stamped under the impact. It can be suitable for punching and stamping work in different directions and different working surfaces. Compared with the method of striking the punch with a hand hammer in the prior art, the stamping force of the punch head 1 is greater, which can meet the depth of the punch mark, and the clarity is correspondingly improved, and the labor intensity of the operator can also be reduced. Secondly, for the punching work in the supine area, compared with the method of holding the punch by hand and using a hammer to hit in the opposite direction in the prior art, it can avoid the phenomenon of the hammer hitting the operator, improve the operator's work safety performance, and at the same time, it can also reduce the phenomenon of the punch 1 deviating from the line, thereby improving the accuracy. In addition, in this tooling, since the punch 1 is coaxially arranged with the central passage 21, and the handle 4 is arranged vertically with the round rod 3, therefore, in the process of the upper end of the round rod 3 hitting the lower end of the punch 1, the force can be more concentrated to avoid the impact force from being offset, thereby further reducing the phenomenon of the punch 1 deviating from the line, and ensuring the smooth progress of subsequent operations.
[0027] Exemplarily, when the upper end of the round rod 3 abuts against the lower end of the foreign punch 1, part of the round rod 3 extends out of the round tube 2 and forms a protrusion 5. It can be understood that the length of the protrusion 5 is a safe distance for operation, and in the process of the upper end of the round rod 3 hitting the lower end of the foreign punch 1, the operator's hand can be prevented from being pinched, thereby further improving the safety performance of the tooling during operation.
[0028] Exemplarily, in order to facilitate the operator to hold the round tube 2 more conveniently, a handle 6 is fixedly connected to the outer side of the round tube 2.
[0029] Exemplarily, in order to improve the connection between the parts of the tooling and avoid loosening during operation, the handle 6 is welded to the round tube 2; the punch 1 is welded to the round tube 2; and the round rod 3 is welded to the handle 4.
[0030] For example, in order to improve the overall structural strength of the tooling, the punch 1, the round tube 2, the round rod 3, the handle 4 and the handle 6 are all made of steel.
[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
