Description

Technical Field

[0001] This invention belongs to the field of radial forging and forming technology, specifically relating to a rotary forging clamping and feeding device for irregularly shaped bars. Background Technology

[0002] Shaped bars are non-circular cross-section bars with broad application prospects. Currently, the commonly used technology for manufacturing shaped bars is extrusion technology. This method relies on axial pressure to cause deformation, resulting in a large deformation ratio. It has high requirements for processing pressure and temperature, a narrow range for feed rate control, and the extruded billet is prone to breakage during processing, making it difficult to process bars with particularly large length-to-diameter ratios.

[0003] Rotary forging is a forming method in which the die hammer repeatedly forges the workpiece while rotating, causing deformation through radial pressure. It has advantages such as low processing pressure, wide range of feed speed control, suitability for processing long bars, easy continuous operation, and high processing efficiency. It is currently widely used in the production of shaft parts in the automotive manufacturing industry.

[0004] Due to the limitations of rotation characteristics, existing rotary forging dies can only process bars or tubes with circular cross-sections. In order to obtain the ideal outer circle, the feeding fixture or bar clamping device ensures that the bar does not rotate with the die.

[0005] Therefore, existing bar clamping devices cannot achieve synchronous rotation of the bar and the rotary forging die, and cannot meet the manufacturing requirements of irregular bars with non-circular cross-sections. Summary of the Invention

[0006] The purpose of this invention is to provide a rotary forging clamping and feeding device for irregularly shaped bars, which can ensure that the bar material rotates synchronously with the forming die during the rotary forging process and feed the bar material as required, thereby realizing continuous rotary forging of irregularly shaped bars.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A forging clamping and feeding device for irregularly shaped bars includes a processing chamber mounted on the top of the spinning machine body, and a feeding platform connected parallel to the upper surface of the spinning machine body. A guide shaft is mounted on the side of the rotating shaft of the processing chamber. A spring is sleeved on the guide shaft, with one end of the spring contacting the rotating shaft and the other end contacting the clamping component. A stepper motor is mounted on the feeding platform, and the rotating shaft of the stepper motor is connected to a bolt rod via a coupling. The other end of the bolt rod is connected to a bearing seat A. A bolt sleeve is sleeved on the bolt rod, and a bearing seat B is mounted on the bolt sleeve. A guide rail is installed below the bolt sleeve. The bearing seat B is connected to the bar stock via a connecting sleeve.

[0009] A feed platform is welded parallel to the upper surface of the spinning machine body.

[0010] Four guide shafts are evenly distributed on the side of the rotating shaft.

[0011] The clamping component has several through holes and threaded holes on its front side.

[0012] The through hole and the guide shaft are fitted with a clearance.

[0013] The threaded hole is equipped with a fixing bolt.

[0014] The connecting sleeve has a threaded through hole on its outer diameter.

[0015] The threaded through hole is fitted with a fastening bolt.

[0016] The spring fitted on the guide shaft is always kept in a compressed state.

[0017] The irregular mold is set on the side of the rotating shaft.

[0018] The beneficial effects achieved by this invention are as follows:

[0019] The present invention proposes a rotary forging clamping and feeding device for irregularly shaped bars, which can ensure that the irregularly shaped bar material rotates synchronously with the rotary forging die during the rotary forging process, and feed the relatively rotating bar material as required, thereby realizing continuous rotary forging of irregularly shaped bars.

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] A forging clamping and feeding device for irregularly shaped bars includes a bar clamping device and a bar feeding device;

[0026] The bar stock clamping device includes components such as a guide shaft fixed on the rotating shaft, clamping parts, springs, and fixing bolts, to ensure that the bar stock and the rotating forging die rotate synchronously during the rotary forging process; the bar stock feeding device includes components such as a stepper motor, bolt rod, bolt sleeve, bearings, couplings, fastening bolts, and connecting sleeves to complete the continuous feeding of the relatively moving bar stock.

[0027] A processing chamber 2 is installed at the top of the spinning machine body 1, and a feed platform 3 is welded parallel to the upper surface of the spinning machine body 1. Guide shafts 8 are installed on the side of the rotating shaft 5 of the processing chamber 2, and four guide shafts 8 are evenly distributed on the side of the rotating shaft 5. A spring 7 is sleeved on the guide shaft 8, one end of the spring 7 contacts the rotating shaft 5, and the other end contacts the clamping part 9. The clamping part 9 has several through holes and threaded holes on its front. The through holes are clearance-fitted with the guide shafts 8, and the threaded holes are fitted with fixing bolts 10. A stepper motor 18 is installed on the feed platform 3. The rotating shaft of the stepper motor 18 is connected to the bolt rod 13 through a coupling 17. The other end of the bolt rod 13 is connected to the bearing seat A11. A bolt sleeve is sleeved on the bolt rod 13, and a bearing seat B16 is mounted on the bolt sleeve. A guide slide rail 12 is installed below the bolt sleeve. The bearing seat B16 is connected to the bar stock 4 through a connecting sleeve 14. The connecting sleeve 14 has a threaded through hole on its outer diameter, and a fastening bolt 15 is fitted on the threaded through hole. The spring 7 fitted on the guide shaft 8 is always kept in a compressed state. The irregular mold 6 is located on the side of the rotating shaft 5.

[0028] A rotary forging clamping and feeding device for irregularly shaped bars involves placing the bar stock through the clamping device into the mold, connecting the tail end of the bar stock to the connecting sleeve, tightening the fixing bolts of the clamping device to lock the bar stock in place, and then tightening the fastening bolts to achieve relative rotation of the bar stock relative to the mold. During the bar stock forming process, if forward feeding of the bar stock is required, a stepper motor can drive a bolt rod to rotate. The bolt rod drives a bolt sleeve, which in turn drives the bearing seat and the bar stock forward, thus completing the feeding of the rotating bar stock.

[0029] This invention belongs to the field of rotary forging technology, specifically for clamping and feeding during rotary forging of irregularly shaped bars. It includes a bar clamping device and a feeding device. The bar clamping device includes a guide shaft fixed on a rotating shaft. A clamping component and a spring are sleeved on the guide shaft. The clamping component has several through holes and threaded holes, with fixing bolts fitted into the threaded holes. The bar feeding device includes a base, on which a stepper motor is mounted. One end of the rotating shaft of the stepper motor is connected to a bolt rod via a coupling. A bolt sleeve is sleeved on the bolt rod, and a bearing base is mounted on the bolt sleeve. A guide rail is fitted below the bolt sleeve, and a connecting sleeve is fitted on the bearing base to connect with the bar. The connecting sleeve has threaded holes, with fastening bolts fitted into the threaded holes. This invention, through the clamping and feeding mechanisms, allows the irregularly shaped bar to rotate relative to the mold and be continuously and evenly fed into the mold, thus realizing the processing of irregularly shaped bars.
