Description

Description of the invention Title of the invention Hammer with rotating arm Technical background of the relevant invention This invention relates to the field of industries and metals. Technical problem and stating the objectives of the invention In various industries, including the metalworking and blacksmithing industries, for shaping hot metals or hammering and installing metal parts in steel structure workshops, hammering large nails into parts or repairing heavy metal parts and crushing rocks, it is usually necessary to use heavy hammers and human labor, not machines. In order to do the above and other tasks, workers are forced to use large and heavy hammers. This can have several problems. These problems include high physical and bodily harm to workers, which is the most important problem, as well as physical fatigue, the need to hire more labor, the possibility of life and physical hazards such as injury to the hands or feet of workers due to the wrong hammer hitting these members and resulting fractures or amputations, and the time-consuming nature of doing things manually. The purpose of this invention is to make this device easier and safer to use when used in the aforementioned industries. A description of the state of the prior art and the history of developments related to the claimed invention. Currently, there are various types of hammers and mallets on the market, but except in large and industrial factories, the use of a hammer requires manpower and manual labor, and there is no invention that can safely replace manual labor in smaller industries. Providing a solution to an existing technical problem along with an accurate, sufficient, and integrated description of the invention As mentioned, in various metalworking, blacksmithing and other industries, there is a need to use human power to hit heavy hammers to harden metals or drive large nails into wooden or metal parts. The human power takes the hammer in its hand and, by determining the appropriate location, repeatedly hits the desired part with the hammer. This work continues until the desired result is achieved. In large industrial factories, numerous mechanical devices with different applications are used for this purpose. However, in many industries and affairs, due to the high delicacy of the work or the high cost of purchasing mechanical devices and setting up a production line, human power is still needed to do this work, which can cause numerous problems. These problems include long-term physical and mental damage to the worker, the possibility of serious physical injury if the hammer is mistakenly hit on the hand or foot, fatigue and disability of the worker, the lengthening of the work process, the need for multiple human forces, and higher labor costs.Our claimed invention attempts to solve these problems by making the device consist of a rotating arm, a single-tooth worm gear, and various associated levers. By rotating the rotating arm, the hammer is raised and released at a certain height, and then struck against its base or any device on the base. This device is made of various components, which, in order with the functionality of each part, are: a rotating arm (1), which has a handle for easy handling with one or two hands, a mallet (2) with a replaceable head for using different sizes, which is connected to the central lever (5) with a fixed rod, a single-tooth worm gear (3), which has one tooth that creates a height difference on the outer surface of the worm circle, the holding legs on both sides of the tool (4), which are arranged in a three-legged and two-sided position to ensure a stable and firm placement of the device, the central lever (5) which is connected to two rods from the front and rear-upper sides, the front rod is connected to the mallet head, and the upper rear rod (10) has a free end thatIt is supported by a single-tooth worm gear (10). The device also has two upper (6) and lower (7) central connecting rods, which connect the two support legs and also cause the rotation of the single-tooth worm gear and the movement of the central lever. The upper central connecting rod is fixedly connected to the rotating arm and the single-tooth worm gear, so that by rotating the rotating arm, the upper central rod and, consequently, the single-tooth worm gear begin to rotate. The lower central rod is also fixedly connected to the central lever. This tool also has a fixed hammer base (8) for placing the tools to be struck by the hammer, which can be replaced with different sizes and heights to adjust the power and height of the hammer, so that by replacing this part and placing a base with a higher height, the hammer is released from a shorter distance and strikes this base, and therefore it will have less striking power and vice versa, and the main plate of the base (9) is for mounting components and parts on it and for the device to be fixed on the ground. The way the device works is as follows:The desired tool that needs to be hammered is placed on the fixed base surface of the hammer, and then by rotating the rotating arm towards the front of the tool, the upper central connecting rod and the single-tooth worm gear begin to rotate. Due to the unequal radius of the worm gear and the greater radius at the location of the tooth and the proximity of the tooth due to rotation to the leaning head of the posterior-upper rod of the central lever, this rod is pushed downwards. Since it is fixedly connected to the central lever and the central lever is also connected to the lower central connecting rod, and therefore has the power of a rocking motion, and this central lever is also connected to the hammer from the front, due to this pressure and downward movement of the posterior-upper rod and the aforementioned connections, the hammer head is moved in the opposite direction and upwards. Then, as the rotation continues and the gear tooth reaches the cutting end of the posterior-upper rod of the central lever, this rod reaches the tooth and suddenly, due to the presence of The tooth and the difference in height and weight resulting from the raised hammer, the posterior-upper bar of the tooth and the direction of the raised hammer toothIt is released and hits the fixed base surface with a hammer or any device located on this part. This operation can be repeated as many times as needed by rotating the rotating arm until the desired result is achieved. Also, this device does not depend on electricity and can be used anywhere. Explanation of shapes, maps and diagrams Figure 1, which is scaled to meters, shows the general view of the invention. The inventive device is made of the following components: the main base plate (9), which is an iron rectangle 3 meters long and 1.5 meters wide, which is not made as a single plate in order to lighten the overall weight of the device and make it easy to transport, and only has the necessary connections, and the rest of its parts are empty, the support legs on both sides of the device (4), which are placed on the main base plate in the form of a tripod to strengthen the device and are connected to it, and the height of each of them on both sides is 1.60 cm. The upper and lower central connecting rods (6 and 7) which are located inside the body of the support legs and are rotatable. The upper central connecting rod (6) is installed at the top of the support legs and is fixedly connected to the rotating arm (1) and the single-tooth worm gear (3). The lower central connecting rod (7) is also fixedly connected to the central lever (5).The rotating arm (1) has a handle that is the location of one or both hands to rotate the rotating arm towards the front of the device. The single-tooth worm gear (3) which has one tooth to change the radius on the surface of the piece also has a fixed connection to the upper central connecting rod and as mentioned the upper central connecting rod also has a fixed connection to the rotating arm so that by rotating the rotating arm towards the front, the upper central connecting rod and the single-tooth worm gear start to rotate. This device is also made of a hammer (2) which has the ability to change the head to different dimensions and sizes, the head of the hammer is connected to the central lever (5) through a rod. Inside this lever, there is a lower central connecting rod which causes the central lever to rotate.This lever is connected from the rear-upper side (10) to a rod that has a free end supported by a single-tooth worm gear that slides on the rim of this gear as the single-tooth worm gear rotates until it reaches the gear tooth. The device is also made of a fixed hammer base (8) that is the location of the objects to be hammered and can be changed to different sizes and heights to control the strength of the hammer blows.

Claim 2) According to claim 1, the device consists of a main base plate for mounting the other components of the claimed invention on it. In order to make the device lighter and easier to carry, it is not made in one piece and only has the necessary connections. The material of this plate is stainless steel. Claim 3) According to claim 1, the device has two support legs on both sides, which are designed in the form of a tripod to provide greater strength and prevent the device from falling. Claim 4) According to claims 1 and 3, in order to position the support legs in a fixed position opposite each other, two connecting rods are used to hold the left and right support legs in a fixed position opposite each other. Claim 5) According to claims 1 and 4, the upper connecting rod has the power to rotate and is also fixedly connected to the rotating arm and the single-tooth worm gear. Claim 6) According to claim number 5, due to the fixed connection of the upper connecting rod to the rotating arm, simultaneously with the rotating arm rotating towards the front of the device, the upper connecting rod also starts to rotate, the direction of rotation of the rotating arm is only one-way and towards the front of the device. Claim 7) According to claims 5 and 6, the device is made of a main part called a single-tooth worm gear, which is fixedly connected to the upper central connecting rod, and when this rod rotates, the single-tooth worm gear also starts to rotate. Claim 8) According to claim 7, the single-tooth worm gear has a smooth outer edge and one tooth, the presence of which leads to a difference in radius in its circular surface, such that the radius of this surface at the location of the tooth is greater than the radius of other parts. Claim 9) According to claims 1 and 3, the device also has a lower central connecting rod, which is rotatable and is also fixedly connected to the central lever. Claim 10) According to claim 9, the central lever is a hinge-shaped piece that is connected from the front side to a rod connected to the hammer head and from the rear-upper side to a rod that has a free end resting on the outer edge of the single-toothed worm gear. Claim 11) According to claim 5, 6, 7, 8 and 10, as a result of rotating the rotating arm towards the front of the device, the upper central connecting rod and the worm gear begin to rotate. Meanwhile, the free end of the posterior-upper rod of the central lever is supported by the outer and smooth edge of the worm gear due to the weight of the hammer head. Simultaneously with the rotation of this gear, due to the unequal radius of the circular plate of the gear and the arrival of its tooth (which has the largest radius) to the supported end of the posterior-upper rod of the central lever, this results in downward pressure on this rod. Due to the connection of this rod to the central lever and the connection of the central lever to the lower central connecting rod that can rotate, this lever also performs its hinged movement and, as a result of the connection of this lever to the hammer head through the anterior rod, the hammer head is finally moved upwards due to the resulting pressures. Claim 12) According to claim 1, 7, 8, 10 and 11, after the tooth (which has the largest radius in the circular plane of the single-toothed worm gear) reaches the upper rear rod of the central lever, the hammer head is at its highest height from the fixed base of the hammer. Then, as this tooth passes due to continued rotation, due to the emptying and removal of pressure from the free head, the upper rear rod of the central lever rests on the outer edge of the worm gear and due to the force of gravity and the weight of the hammer, the hammer is released and hits its lower fixed base or any device placed on it. Claim 13) According to claims 1 and 12, the device is made of a mallet with the ability to change the head, size, and weight, as well as a fixed base of the mallet with the ability to move and change to other dimensions and heights, and the ability to move and change this piece to other pieces with a lower or higher height can help adjust the strength of the hammer's blows, such that by changing this piece to a piece with a higher height, the distance between the height of the mallet and the base plate becomes smaller and the mallet hits this base with less speed and force, and vice versa.
