[0002] In the fields of industrial manufacturing, metal processing, etc., steel stamps are generally used to mark information such as product numbers, trademarks, dates, etc. on the product surface. The existing manual marking method is that operators use tools such as hammers and pliers to strike a steel die, leaving a mark on the product surface. This method has high requirements for the skills of operators, is not convenient to operate, has great potential safety hazards, and it is difficult to ensure the stability and consistency of the markings. The existing automatic marking machines are mainly divided into electric marking machines and air pump marking machines. Such equipment usually requires an external power supply or air pump, has a large weight, and is poor in operation flexibility and portability. In addition, due to the presence of many electrical components inside the equipment, its applicability is limited in high-temperature or complex working environments. Summary of the Invention

[0003] The purpose of the present invention is to provide a manual mechanical marking machine, and the manual mechanical marking machine is to solve the technical problems in the existing manual marking method that it is not convenient to operate, the stability and consistency are difficult to guarantee, the portability of the automatic marking machine is poor, and its applicability is limited in high-temperature or complex working environments.

[0004] A manual mechanical marking machine of the present invention includes a gun body. A cylindrical inner cavity is provided inside the gun body. A cylindrical mandrel is coaxially arranged in the inner cavity of the gun body. The mandrel and the gun body form a sliding pair parallel to the axial direction of the inner cavity of the gun body and a rotational pair in the circumferential direction. A joint is connected to the front end of the mandrel. After the front end of the joint extends out of the gun body, a steel stamp head is connected.

[0015] The present invention will be further described below in conjunction with embodiments, but the present invention is not limited to these embodiments. Any similar changes adopted in the present invention should be included in the protection scope of the present invention. The use of directions such as up, down, front, back, left, right, middle, inside, and outside in the present invention is only for the convenience of clear description and is not a limitation to the technical solution of the present invention.

[0016] As Figures 1 - 5As shown in the figure, a manual mechanical marking machine of the present invention includes a gun body 1. A cylindrical inner cavity is provided in the gun body 1. A cylindrical mandrel 2 is coaxially arranged in the inner cavity of the gun body 1. The mandrel 2 and the gun body 1 form a sliding pair parallel to the axial direction of the inner cavity of the gun body 1 and a rotational pair in the circumferential direction. A connector 3 is connected to the front end of the mandrel 2. After the front end of the connector 3 extends out of the gun body 1, it is connected to a steel stamp head. A spring 4 is arranged between the rear end of the mandrel 2 and the rear end face of the inner cavity of the gun body 1. A handle 5 is fixedly arranged on the lower side of the gun body 1. A wrench 6 is movably installed on the handle 5. A wrench arm 7 is fixedly connected to the upper side of the wrench 6. The wrench arm 7 extends into the inner cavity of the gun body 1. A chute 15 for the wrench arm 7 to extend into is arranged in the side wall of the gun body 1. The wrench arm 7 is located on the front side of the mandrel 2. The wrench arm 7 and the gun body 1 form a sliding pair parallel to the axial direction of the gun body 1. An energy storage and release inclined groove 8 is arranged in the side wall of the gun body 1. The energy storage and release inclined groove 8 is arranged along the circumferential direction of the gun body 1. The energy storage and release inclined groove 8 includes at least two energy storage and release inclined groove units connected end to end. Any one of the energy storage and release inclined groove units includes at least two energy storage inclined grooves 9 and one energy release inclined groove 10 connected in sequence. A buffer groove 11 is connected between any two adjacent energy storage inclined grooves 9. A limiting rod 12 with the same number as the energy storage and release inclined groove units is fixedly arranged on the outer side surface of the mandrel 2. The limiting rod 12 is slidably arranged in the energy storage and release inclined groove 8.

[0017] Further, the number of the wrench arms 7 is two, which are respectively located on both sides of the connector 3.

[0018] Further, a slideway 13 is axially arranged in the side wall of the gun body 1 away from the handle 5. The upper end of the wrench arm 7 is arranged in the slideway 13.

[0019] Further, the number of the energy storage inclined grooves 9 in any one of the energy storage and release inclined groove units is four.

[0020] Further, a fixing rod 14 is coaxially connected to the rear side of the mandrel 2. The rear end of the fixing rod 14 extends out of the gun body 1. The spring 4 is sleeved on the fixing rod 14.

[0021] The working principle of the present invention: In the initial state, the limit rod 12 is located at the bottom of the first energy storage inclined groove 9. When the fastening wrench 6 is pulled, the wrench 6 drives the wrench arm 7 to move backward. The wrench arm 7 drives the mandrel 2 to move backward. The limit rod 12 on the mandrel 2 moves upward along the first energy storage inclined groove 9. The mandrel 2 rotates simultaneously to cooperate with the oblique movement of the limit rod 12, and the spring 4 compresses to store energy. When the wrench 6 is released, the limit rod 12 slides along the first buffer groove 11 and gets stuck at the bottom of the second energy storage inclined groove 9. The position of the mandrel 2 moves backward once, completing one energy storage process. Then, the wrench 6 is pulled repeatedly, and the position of the mandrel 2 moves backward multiple times, causing the spring 4 to be compressed and store energy multiple times. When the wrench 6 is pulled for the last time, the limit rod 12 crosses the top of the last energy storage inclined groove 9, and the energy accumulated by the spring 4 is released. The axial thrust acting on the mandrel 2 is greater than the binding force of the human hand on the wrench 6. The limit rod 12 slides rapidly along the energy release inclined groove 10, and the mandrel 2 drives the joint 3 and the stamping head to impact forward rapidly, completing one marking operation.

[0022] The present invention is an industrial mechanical marking machine without an external power source. The marking machine has a pistol-like structure. By manually operating the wrench 6 to store energy multiple times and cooperating with the energy storage and release inclined groove 8, it can stably achieve energy storage and release and complete the marking operation. Compared with the existing manual marking method, it is easy to operate, has good stability, and high safety. The marking machine has a pure mechanical structure and does not contain electrical components. Compared with the existing automatic marking machines, it does not require power source supporting facilities, reducing the use cost and maintenance cost. It has a competitive advantage in high-temperature operation scenarios such as forging, smelting, and heat treatment, and is especially suitable for working environments without power supply or air pump support, significantly improving portability and applicability.
