Description

1 TARIFF A POLISHING MACHINE Technical Area The invention relates to a polishing machine. The invention specifically concerns screws used in plastic injection and extrusion production. It relates to a machine used in polishing. State of the Art Today, polishing applications in the screw barrel industry are performed using belt sanders and hand tools. is being done. In the current practice, screws are fastened between the centers, and for large surfaces and thread spacing of 10 It is polished with a belt sander. In smaller areas where the belt sander cannot reach, it is done by hand. The tools used in these applications have a low workload per unit time and polishing. Equipment consumption is high. Personnel competence varies from person to person in this application. It is very prominent and metal that threatens the health of workers in conventional methods. Dust particles are scattered into the air and inhaled. 15 Another existing mechanical polishing method is vibratory polishing. In this method, the products and Ceramic stones are placed inside a drum and moved by means of vibration. The stones work By rubbing it against the parts, it polishes their surfaces and produces a mirror-like image. This These devices eliminate the problems mentioned above, such as dealing with large and heavy screws. Not suitable for polishing parts. 20 As a result of the research conducted on the subject, the document numbered TR2024 / 014349, “POLISHING An application titled "MACHINE" was found. In this application, the surface of the workpieces was described. used in polishing processes, automatically polishing the workpiece. and ensuring the same roughness on all surfaces to be polished. 25 from the polishing machine which ensures the homogeneous application of the values It is mentioned. 2 In conclusion, due to the negative aspects described above and the current solutions being the subject of discussion... Due to its shortcomings, an improvement is needed in the relevant technical field. It has been made. Purpose of the Invention The invention was created by drawing inspiration from existing situations and addressing the aforementioned drawbacks. 5 It aims to solve the problem. The main purpose of the invention is to improve the conventional methods mentioned in the current technology. a product designed differently according to its dimensions, overcoming its disadvantages The goal is to develop a vibrating polishing machine. Another purpose of the invention is to move a circular path in the desired direction (clockwise and counterclockwise) using a gearbox. movement is provided and workpieces undergo vibrating motion with hydraulic cylinders. by making contact with ceramic tiles in a highly homogeneous manner, the desired surface quality and The goal is to ensure it reaches its full shine. Large and heavy parts are polished using vibrating polishing machines. It is not suitable for machines with masses between 20 and 1000 kg. Because these changing parts are not strong enough to move during polishing, 15 The parts cannot rotate around their own axes and therefore cannot be homogeneous. It cannot be polished. Between the surfaces of the workpieces that come into contact with the stones and other surfaces. There will be a significant difference in quality. To avoid this, rotate the parts. a different mechanism emerged that distinguishes its mechanism from the vibration mechanism It has been placed. 20 The structural and characteristic features and all the advantages of the invention are given in the figures below. This becomes clearer thanks to the detailed explanation written with references to these figures. This will be understood as such, and therefore the evaluation will also take these forms and detailed explanations into account. This should be done taking that into consideration.

The polishing machine, the subject of the invention, is shown in perspective view in Figure 5, and consists of a base chassis. It is built on the base chassis group (13) (main chassis group). There are cradle carrier bearing housings (15). On the cradle carrier bearing housings (15) spindle assembly (2), axially moving six-point rotary assembly (6), liquid feed 10 group (4), cylindrical polishing cabinet (20), cylindrical polishing cabinet (20) mounted The lantern shaft bearing housings (3), reducer assembly (1), cradle chassis assembly (12) move There is a hydraulic cradle vibration cylindrical group (10) that performs cylindrical polishing. inside the cabinet (20) there are 1, 2, 3, 4 and 6 screws to be polished (7) There are six rotary groups with six points that we can connect. Screws (7) and polishing 15 Loading and unloading of stones, lid of cylindrical polishing cabinet (20) (9) This is done when it is opened. During filling and emptying, both the liquid, the stones, and the polishing compound are involved. The resulting sludge-like waste liquid is discharged onto the discharge pan (14). Our main body will be rigidly mounted to the concrete. The capacity of the polishing machine. Designed to polish screws (7) with lengths between 1400-3400 mm. It has been made. Screws (7) are attached to the cylindrical polishing cabinet (20) on the cradle chassis group (12). After it is placed inside, abrasive polishing stones will be placed and the cabinet door (9) It will be closed. With the start command, the circular motion taken from the gearbox group (1) cylindrical polishing cabinet (20) in axial position at specified times one to the right one to the left It will perform a rotational movement. At the same time, 25 of the hydraulic cylinders that we have specified will be used. The motion received at the frequency will be transmitted to the system. During this process, the abrasive polishing stones... To prevent it from drying out, polishing fluid is automatically supplied through the liquid supply group (4). It will be fed.

The particles formed during the erosion process can mix with the air and pose a risk to human health and the environment. The purpose is to prevent damage. Also, in normal vibration machines, 5 There is also the loud noise that is produced and can damage the sensory organs. The dB level will be reduced to within the required limits. This is suitable for use with parts of this size. To achieve the desired result with a vibration machine, we need 30 kW. It requires the use of energy. However, the machine we designed requires 8 With an energy output of kW, a working environment that does not harm human health has been achieved. That will be the case. We will place our parts one by one into the machine that we will use for polishing parts of this size. The machine we designed can place 1, 2, 3, 4, and 6 parts simultaneously, whereas we should only place them in one position. This allows for a significant reduction in the amount of work done per unit of time. It increases efficiency and performance, which in turn has a positive effect on cost reduction. It will contribute. 15 The gearbox group (1) is the motor from which the initial movement is obtained. Since it is desired to obtain 72 revolutions Adjustment can be made with a potentiometer. The lantern shaft assembly (2) receives the chain gear. It transmits the movement to the polishing rotary cylinder group (5). The polishing rotary cylinder group (5) moves to the right / left. It rotates at the desired intervals. It also features cradle vibration cylindrical design. Vibration motion is created by the up and down movement of the group (10). Thus, 20 The screws (7) are made to make equal contact at every point. Vibration spring support The group (11) ensures that the movement is smoothed and balanced by springs. The working principle of the polishing machine which is the subject of the invention is as follows: screws (7) are polished by a cylindrical polishing machine. The cabinet (20) (drum) is located horizontally inside the screws (7) and cylindrical polishing In addition to the rotational movement of the cabinet (20), the surfaces of the stones are also vibrated by a vibrational movement. 25 It is based on the principle of polishing. The polishing machine that is the subject of this invention can have different angles and different lengths. The same At the same time, this machine can be configured in a vertical position and a movable drum can be used instead of a drum. A polishing pot can be constructed to allow for polishing of the desired portion of the screw.
