Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to a pressure shaping device for gear processing. Background Art

[0002] Gears are mechanical components with teeth on the rim that can continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. At the end of the 19th century, the principle of gear cutting and the special machine tools and tools that use this principle to cut gears appeared one after another. With the development of production, the stability of gear operation has been paid attention to. Gears can be divided into gear teeth, tooth grooves, end faces, normal faces, tooth top circles, tooth root circles, base circles, pitch circles and other parts according to their structures. Commonly used steels for manufacturing gears are quenched and tempered steel, hardened steel, carburized and hardened steel and nitrided steel.

[0003] The gear processing process is divided into multiple steps, and heat treatment is one of the key steps. When workers perform heat treatment on gears, due to the texture of the material and the geometric shape of the gears themselves, the gears will expand and deform after heat treatment, resulting in the tooth accuracy failing to meet the requirements. Therefore, a shaping machine is needed to process it. Currently, when using a shaping machine to stamp and shape gears, due to the presence of teeth on the outer ring of the gear, the gears are usually manually aligned with the shaping die groove for loading and then manually taken out after stamping. During this process, workers need to put their hands into the shaping working area. If the workers are not strict with the operating steps of the machine, safety accidents may occur. Therefore, there are certain safety hazards. In addition, the manual loading and unloading method is not conducive to improving the efficiency of the shaping process, and the degree of automation is not high. In view of this, we propose a pressure shaping device for gear processing. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet actual needs, and provide a pressure shaping device for gear processing to solve the technical problems that the current gear shaping machine needs to be manually inserted into the shaping processing area to place the gears when in use, which poses a safety hazard and is not convenient for improving processing efficiency.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a pressure shaping device for gear processing, including a stamping shaping machine with a hollow processing area formed inside and a processing component detachably arranged in the hollow processing area;

[0006] The processing assembly includes a processing template with a receiving hole opened in the center of the top, a shaping die groove extending into the stamping and shaping machine is opened in the center of the bottom of the inner wall of the receiving hole, the upper end surface of the processing template is located on one side of the receiving hole and is detachably mounted with a main rack, and the upper end surface of the processing template is located on the other side of the receiving hole and is rotatably and movably mounted with an annular toothed belt, a pushing hydraulic cylinder is provided at the bottom of the interior of the stamping and shaping machine coaxially with the receiving hole, and the top end of the rod body of the pushing hydraulic cylinder is constructed with a pushing piece adapted to be movably and telescopically installed in the shaping die groove, and a shaping hydraulic cylinder is provided at the top of the interior of the stamping and shaping machine coaxially with the receiving hole, and the bottom end of the rod body of the shaping hydraulic cylinder is constructed with a shaping piece adapted to be movably and telescopically installed in the shaping die groove.

[0007] Preferably, a secondary rack is movably mounted on one end of the main rack, and a fixing block 1 is arranged on one end of the main rack facing the secondary rack, and a fixing block 2 is arranged on one end of the secondary rack facing the main rack.

[0008] Preferably, a positioning rod is symmetrically arranged on one side of the fixed block 2 facing the fixed block 1, and one end of the positioning rod away from the fixed block 2 extends through the fixed block 1 and is structured to connect with the limited position block, and a spring is sleeved on the outer edge surface of the positioning rod, and the spring is placed between the fixed block 1 and the fixed block 2.

[0009] Preferably, driving wheels are tensioned and abutted at both ends of the inner part of the annular toothed belt, and a rotating shaft is coaxially configured at the bottom of the driving wheel, and the bottom end of the rotating shaft can be rotatably connected to the processing template.

[0010] Preferably, fixing bolts are equidistantly arranged on one side of the upper end surface of the main rack, and one end of the fixing bolts can be screwed into the processing template.

[0011] Preferably, a blanking plate is fixedly provided on one side of the stamping and shaping machine, and anti-drop baffles are constructed on both sides of the upper surface of the blanking plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By setting the main rack and the annular toothed belt, the gear meshes and enters from the end of the annular toothed belt and the main rack, and moves relative to the main rack on the surface of the processing template with the rotation of the annular toothed belt. When the gear moves to the coaxial position of the accommodating hole, it falls into the accommodating hole under the action of gravity, and the tooth position of the gear matches the shaping die groove. Then the gear is pressed into the shaping die groove by the shaping hydraulic cylinder for shaping. After the shaping is completed, the shaping die groove is pushed out by the push hydraulic cylinder and meshed with the main rack and the annular toothed belt. Then the gear is driven to continue to move through the rotation of the annular toothed belt to realize material discharge. Compared with the traditional shaping machine, workers do not need to reach into the shaping processing area to manually position and place the gear, which is beneficial to improving the processing safety, and can realize automatic loading and unloading of the gear, so that the degree of automation is improved, which is beneficial to improving the shaping processing efficiency.

[0014] 2. By movably setting a secondary rack at one end of the main rack, when the gear is placed on one end of the main rack and the annular toothed belt, the gear is meshed with the secondary rack and loading is performed with the rotation of the annular toothed belt. When loading, the gear is meshed with the secondary rack and pushed toward the main rack, so that the gear and the annular toothed belt are automatically meshed to complete the loading. After the loading is completed, the secondary rack is reset by the elastic force of the spring, which is conducive to rapid meshing and loading, convenient for operators to perform loading work, and less likely to cause gear jamming during loading.
