Description

Technical Field

[0001] This utility model belongs to the technical field of stamping device manufacturing, and specifically relates to a handheld stamping device. Background Technology

[0002] A stamping device is a tool used to mark material surfaces. Its main function is to transfer letters, numbers, or patterns from a steel stamp onto the material surface by applying impact force to surfaces such as metal, plastic, and wood. The stamp can be letters, numbers, trademarks, or other identification symbols, and is widely used in industrial manufacturing, product certification, product traceability, and quality control. A stamping device typically consists of a steel stamp, a striking mechanism, and a positioning system. In use, the stamp is imprinted onto the target material surface by striking, impacting, or pneumatically actuating. This device is used in many industries, such as machinery manufacturing, the automotive industry, electronic component production, and jewelry marking.

[0003] Currently, stamping devices on the market can be divided into manual, pneumatic, and electric types. Each type of device has its applicable scenarios and limitations. Manual stamping devices are usually operated manually, relying on a hammer or other striking tools to strike the stamp. Their advantages are simple operation, low cost, and simple structure, making them suitable for small-batch production and small workplaces. However, they also have several disadvantages: consistent striking force and position control can easily lead to blurred, faint, or incomplete stamping patterns; furthermore, human error during striking can cause inaccurate stamping positions, affecting the quality of the marking. Pneumatic stamping devices use a pneumatic system to provide power, enabling the stamp to generate a strong impact force in a short time. Their advantage is that they can provide more uniform and greater striking force, making them suitable for mass production. However, pneumatic stamping devices are usually larger, limiting their application range and making them unsuitable for confined working environments; in addition, due to their complexity, specialized operating skills are required, and maintenance costs are higher. For small workpieces or imprinting tasks requiring precise positioning, pneumatic striking devices may not be flexible enough. Electric striking devices combine electric motors and electronic control technology, using an electric drive system to automatically strike the stamp. Compared to pneumatic devices, electric devices offer more precise control and are relatively smaller, making them suitable for small and medium-sized enterprises. However, these devices still suffer from similar issues to pneumatic devices, such as greater complexity, higher operator skill requirements, and higher costs. For specialized process requirements, the adaptability of electric devices may still be somewhat limited.

[0004] In general, most existing stamping devices have the following common drawbacks: due to the lack of precise control, traditional stamping devices are prone to producing blurry and incomplete imprints, especially when the stamping surface is uneven or the operation is improper. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model proposes a handheld stamping device that can effectively solve the problems of blurred or incomplete stamping caused by uneven stamping surfaces or limited working space.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A handheld stamping device includes a handle, a sleeve, a support rod, and a punch body. The sleeve is connected to the handle, and a buffer elongated hole is opened in the middle of the punch body. The support rod passes through the buffer elongated hole and is connected to the inner wall of the sleeve.

[0007] By adopting the above technical solution, a buffer elongated hole is opened in the middle of the punch body, through which the support rod passes and connects to the inner wall of the sleeve. This allows the punch body to move up and down within the sleeve without restriction and remains stable, ensuring that the punch body maintains an appropriate position during operation and avoiding blurry or incomplete stamping caused by uneven stamping surfaces. This stamping device can operate flexibly in confined spaces or complex working environments, without requiring large-scale equipment or complex pneumatic or electric devices. Its compact structure and ease of operation allow for stamping operations in narrow spaces, providing greater flexibility. Through the cooperation of the buffer elongated hole and the support rod, this device can effectively and evenly transmit the striking force to the punch body, thereby reducing the problems of blurry or incomplete stamping caused by uneven striking, unstable positioning, or inconsistent force, ensuring that each strike leaves a clear and complete stamped mark.

[0008] In a further configuration, the sleeve has a first through hole and a second through hole, the first end of the support rod passes through the first through hole, and the second end of the support rod is inserted into the second through hole.

[0009] By adopting the above technical solution, the support rod is fixedly connected to the sleeve through the first and second through holes, ensuring that the support rod will not shift or loosen during operation. The stability of the support rod is improved, allowing the punch body to maintain a precise position and avoiding blurred or incomplete stamping due to unstable support. The two through holes within the sleeve precisely guide the movement path of the support rod, effectively preventing shifting or misalignment during striking. This ensures that the striking force is transmitted evenly and stably to the punch body, resulting in clear and consistent stamping marks and improving the accuracy and reliability of the stamping device.

[0010] In a further configuration, the first end of the support rod is formed with an external thread, and the support rod is connected to the nut through the external thread.

[0011] By adopting the above technical solution, and designing the first end of the support rod to have an external thread, which is then connected to it via a nut, the user can easily adjust the position of the support rod. Rotating the nut allows for precise adjustment of the length or position of the support rod, ensuring accurate positioning of the punch body within the sleeve. This enables the device to adapt to workpieces of different sizes or different working environments. The external thread and nut design simplify the connection between the support rod and the sleeve, facilitating assembly and disassembly. Users can easily install or remove the support rod simply by rotating the nut, reducing operational difficulty and improving equipment maintainability. For parts replacement or cleaning and maintenance, users can quickly disassemble the equipment, enhancing ease of use.

[0012] Furthermore, one end of the punch body is a striking head, and a punch pattern protrusion is formed at the striking head.

[0013] By adopting the above technical solution, the raised pattern formed at the striking head can ensure that the contact between the pattern and the material surface is more uniform and deeper when striking, thereby achieving a clearer and more complete steel stamping effect. Even when the surface is uneven or the material is hard, the steel stamp pattern can still be clearly seen.

[0014] In a further configuration, one end of the sleeve is flat, and the striking head is located at the flat end of the sleeve.

[0015] By adopting the above technical solution, one end of the sleeve is flat, allowing the device to be placed stably on the working surface, ensuring that the striking head makes precise contact with the working surface with each strike. The flat design avoids uneven distribution of striking force caused by uneven or tilted placement, guaranteeing the consistency and clarity of the stamped pattern. The striking head being located at the flat end of the sleeve ensures that the contact between the striking head and the working surface remains parallel, thereby improving the striking effect. The flat design also makes the force transmission more even during striking, avoiding impact imbalance caused by incorrect angles, thus improving the clarity and integrity of the stamped pattern.

[0016] Furthermore, the length of the punch body is greater than the length of the sleeve cavity, and the diameter of the punch body is smaller than the inner diameter of the sleeve.

[0017] By adopting the above technical solution, the length of the punch body is greater than the length of the sleeve's inner cavity. This means that the punch body has a certain amount of free movement space within the sleeve, allowing it to move freely up and down during the stamping process. This ensures that the striking force is fully utilized during striking and guarantees the clarity and consistency of the stamped pattern. Because the diameter of the punch body is smaller than the inner diameter of the sleeve, the movement of the punch body within the sleeve is smoother, preventing issues caused by excessive size or jamming that could affect the performance. This makes the device smoother to use, more flexible to operate, and avoids potential jamming or inaccurate positioning problems.

[0018] Furthermore, the buffer elongated hole is an oblong hole, and the support rod is a cylinder, with the major diameter of the buffer elongated hole being greater than the diameter of the support rod.

[0019] By adopting the above technical solution, the design of the elongated hole allows the support rod to have a certain degree of freedom within the buffer elongated hole, and it can move slightly in the horizontal or vertical direction. This allows the support rod to adjust its position slightly during the tapping process, thereby better adapting to uneven material surfaces or other changes in the working environment, and ensuring the clarity and integrity of the stamp.

[0020] In a further configuration, the sleeve is connected to the handle, and a handle sleeve is provided on the outside of the handle.

[0021] By adopting the above technical solution, the handheld design enables the stamping device to operate flexibly in confined spaces or complex working environments, without requiring large-scale equipment or complex pneumatic or electric devices. Its compact structure and ease of operation allow the device to perform stamping operations in narrow spaces, providing greater flexibility.

[0022] In summary, this utility model has the following beneficial effects: 1. This utility model, through the precise cooperation of the buffer elongated hole, support rod and sleeve, can ensure that the punch body moves stably and smoothly during the working process, avoiding the blurry or incomplete stamping caused by uneven stamping surface or unstable support, and the striking can leave clear and complete stamping marks.

[0023] 2. The compact structure and handheld design of this invention enable flexible operation in confined spaces or complex working environments, avoiding the limitations of requiring large-scale equipment or complex pneumatic devices. Users can complete precise stamping operations within limited spaces, providing greater operational flexibility.

[0024] 3. The support rod and sleeve of this utility model are connected by external thread and nut, which allows users to easily adjust the position of the support rod and accurately adjust the position of the punch body, making the equipment easier to assemble, disassemble and maintain, reducing the difficulty of operation and improving the maintainability and ease of use of the equipment.

[0027] The preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-7 As shown, this preferred embodiment of a handheld stamping device includes a sleeve 1, a support rod 2, and a punch body 3. A buffer elongated hole 3-1 is formed in the middle of the punch body 3. The support rod 2 passes through the buffer elongated hole 3-1, and both ends of the support rod 2 are connected to the inner wall of the sleeve 1. The sleeve 1 has a first through hole 1-1 and a second through hole 1-2. The first end of the support rod 2 passes through the first through hole 1-1, and the second end of the support rod 2 is inserted into the second through hole 1-2. The first end of the support rod 2 has an external thread, and the support rod 2 is connected to a nut 2-1 through the external thread. One end of the punch body 3 is a striking head 3-2, and a punch pattern protrusion is formed at the striking head 3-2. One end of the sleeve 1 is flat, and the striking head 3-2 is located at the flat end of the sleeve 1. The length of the punch body 3 is greater than the inner cavity length of the sleeve 1, and the diameter of the punch body 3 is smaller than the inner diameter of the sleeve 1. The buffer elongated hole 3-1 is an oblong hole, and the support rod 2 is cylindrical. The major axis of the buffer elongated hole 3-1 is greater than the diameter of the support rod 2. Sleeve 1 is connected to handle 4, and handle sleeve 4-1 is installed on the outside of handle 4.

[0029] The working process of this preferred embodiment is as follows: Before use, the first end of the support rod 2 is connected to the nut 2-1 via an external thread and fixed through the first through hole 1-1 and the second through hole 1-2 of the sleeve 1 to ensure that the support rod 2 is in the correct position. The user can adjust the length or position of the support rod 2 by rotating the nut 2-1, thereby accurately positioning the punch body 3.

[0030] The user operates the device by gripping the handle 4. The handle 4 is equipped with a handle sleeve 4-1, which provides a comfortable grip and allows the user to use it flexibly in the work environment.

[0031] When the user strikes the workpiece forcefully, the striking head 3-2 will directly contact the surface of the target workpiece. Due to the raised pattern formed at the striking head 3-2, it is ensured that the contact between the pattern and the workpiece surface is uniform and deep with each strike, thereby achieving a clear and complete stamping effect.

[0032] The punch body 3 is connected to the support rod 2 through the buffer elongated hole 3-1, so that the punch body 3 can move up and down in the sleeve 1, avoiding blurry stamp marks caused by uneven external force or uneven stamp surface.

[0033] The buffer elongated hole 3-1 is designed as an elongated oval hole, and the support rod 2 is cylindrical with a major diameter greater than the diameter of the support rod 2. This allows the support rod 2 to adjust its position appropriately during the striking process, thereby adapting to uneven working surfaces and ensuring the clarity and integrity of the stamped imprint.

[0034] One end of the sleeve 1 is designed to be flat, and the striking head 3-2 is located at the flat end of the sleeve 1, ensuring that the device can be placed stably and avoiding uneven distribution of striking force due to uneven placement or tilting. During each strike, the striking head 3-2 remains parallel to the workpiece surface, ensuring uniform force transmission and improving the quality of the steel stamp.

[0035] The length of the punch body 3 is greater than the length of the inner cavity of the sleeve 1, and the diameter of the punch body 3 is smaller than the inner diameter of the sleeve 1, which allows the punch body 3 to move freely up and down inside the sleeve, providing greater flexibility and avoiding jamming.

[0036] When the user operates the device via handle 4, the force applied by handle 4 is transmitted to the punch body 3 through sleeve 1. Due to the connection between support rod 2 and punch body 3, the striking force can be evenly transmitted to punch body 3 through support rod 2.

[0037] The fixed connection between the support rod 2 and the sleeve 1 ensures the stability of the punch body 3. The adjustment function of the support rod 2 (connected to the nut 2-1 via the external thread) allows the user to precisely adjust the position of the punch body 3, ensuring that the appropriate stamping depth and clarity are maintained with each strike.

[0038] The elongated buffer hole 3-1 allows the support rod 2 a certain degree of freedom during operation, enabling it to adjust its position to adapt to different working surfaces. The shape of the elongated hole allows the support rod 2 to move slightly in the horizontal or vertical direction, thus adapting to uneven surfaces or irregular shapes of workpieces.

[0039] This preferred embodiment achieves uniform transmission of striking force through the precise coordination of the support rod 2, sleeve 1, and punch body 3, ensuring the clarity and consistency of the stamped pattern. Simultaneously, the buffer elongated hole 3-1 and external thread adjustment design enable the device to operate flexibly in complex working environments, providing greater operational flexibility and adaptability.
