Description

Technical Field

[0001] The present invention relates to a material plastic forming device in mechanical engineering, and in particular to a spinning device. Technical Background

[0002] Spinning is an advanced metal forming technology with the characteristics of low material loss, simple process and easy production. It is widely used in reactors, shell casings and cooker funnels. It has unique advantages in forming parts and is an important field of advanced manufacturing technology.

[0003] Most existing pipe spinning processes are thinning spinning. Thinning spinning is achieved by using a spinning wheel to drive the flow of the blank, as demonstrated in Chinese Patent Publication No. CN102554002B. Thinning spinning is a process that involves thickening spinning. The resulting tubular parts have thinner walls and poor formability, hindering subsequent forming processes. Summary of the Invention

[0004] The purpose of the present invention is to provide a spinning device that utilizes a special spinning wheel and forming trajectory to achieve a finished product with a wall thickness thicker than the blank wall thickness, thereby providing more options and possibilities for subsequent forming processing.

[0005] To achieve the above purpose, the present invention has adopted the following technical solutions:

[0006] A spinning device includes a control roller arm part, a control core mold part, and a control roller part. The control roller arm part is composed of a longitudinal moving mechanism, a transverse moving mechanism and a roller arm. The roller arm is installed on the longitudinal moving mechanism, and the longitudinal moving mechanism is installed on the transverse moving mechanism. The longitudinal moving mechanism and the transverse moving mechanism drive the roller arm to move on a two-dimensional plane; the control core mold part is used to drive the core mold to achieve a constant rotation speed of the blank; the control roller part is installed on the support platform of the control core mold part and is connected to the roller arm to realize spinning of the blank.

[0007] Furthermore, the control wheel arm part includes a transverse stepping motor, a transverse screw, a transverse coupling, a transverse housing, a transverse slider, a longitudinal slider, a wheel arm, a longitudinal stepping motor, a longitudinal screw, a longitudinal coupling, and a longitudinal housing. The transverse housing is fixed on the bracket, and a transverse screw is installed in the transverse housing. One end of the transverse screw is connected to the transverse stepping motor through the transverse coupling, and the transverse screw is connected to the longitudinal housing through the transverse slider. A longitudinal screw is installed in the longitudinal housing, and one end of the longitudinal screw is connected to the longitudinal stepping motor through the longitudinal coupling, and the longitudinal screw is connected to the wheel arm through the longitudinal slider.

[0008] Furthermore, the transverse stepping motor controls the forward and backward movement of the longitudinal housing through the transverse lead screw and the slider, and the longitudinal stepping motor controls the left and right sliding of the rotating wheel arm through the longitudinal lead screw and the slider.

[0009] Furthermore, a guide rail is fixedly connected to the bracket, and a longitudinal stepping motor is installed on the guide rail so that the longitudinal stepping motor can slide on the guide rail. The guide rail supports the longitudinal stepping motor and the longitudinal housing, thereby improving the support stiffness of the rotating wheel arm.

[0010] Furthermore, the control core mold part includes a DC reduction motor, a bearing seat, a main shaft, a core mold and a support. The support is fixed on the bracket. The main shaft is supported and connected to the support through the bearing seat. The rear end of the main shaft is connected to the DC reduction motor, and the front end is connected to the core mold after passing through the bearing seat. The front end of the core mold is fixed to the processed blank.

[0011] Furthermore, the control wheel part includes a wheel, a wheel bracket, and a support platform. One end of the wheel bracket is fixed on the support platform and can rotate around the contact point, and the other end is connected to the wheel arm. The wheel bracket has a wheel in the middle.

[0012] Furthermore, when the roller arm pushes the roller bracket to rotate around the contact point, the roller bracket drives the roller to move, thereby realizing spinning of the blank.

[0013] Furthermore, the rotating wheel bracket is L-shaped.

[0014] Beneficial effects of the present invention:

[0015] The spinning device of the present invention is different from the previous cylindrical thinning spinning equipment. The tubular parts produced by thinning and spinning have thin walls and poor formability, which affects the implementation of subsequent forming processing plans. The wall thickness of the finished product processed by the device of the present invention is thicker than that of the blank, providing more options and possibilities for subsequent processing and forming. When the DC reduction motor is working, it drives the blank to achieve the rated speed, and the roller bracket supports the roller. When the two stepper motors are working, they drive the slider to slide, thereby driving the roller arm to move. The roller arm drives the roller to move, realizing the entire process of blank spinning. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 As shown, a spinning device includes a control roller arm part, a control core mold part, and a control roller part.

[0020] The control wheel arm assembly primarily comprises a transverse stepper motor 2, a transverse lead screw 3, a transverse coupling 4, a transverse housing 5, a transverse slider 6, a longitudinal slider 7, a wheel arm 8, a longitudinal stepper motor 17, a longitudinal lead screw 18, a longitudinal coupling 19, and a longitudinal housing 20. The transverse housing 5 is fixed to the bracket 1. The transverse lead screw 3 is mounted within the housing 5. One end of the transverse lead screw 3 is connected to the transverse stepper motor 2 via the transverse coupling 4. The transverse lead screw 3 is connected to the longitudinal housing 20 via the transverse slider 6. The longitudinal housing 20 houses the longitudinal lead screw 18. One end of the longitudinal lead screw 18 is connected to the longitudinal stepper motor 17 via the longitudinal coupling 19. The longitudinal lead screw 18 is then connected to the wheel arm 8 via the longitudinal slider 7. When commands are given to the transverse stepper motor 2 and the longitudinal stepper motor 17, they rotate, respectively driving the transverse lead screw 3 to rotate. The transverse lead screw 3 controls the forward and backward movement of the slider 6, while the longitudinal lead screw 18 drives the left and right sliding of the longitudinal slider 7. When the two motors move simultaneously, the two-dimensional plane motion of the rotary arm 8 can be achieved.

[0021] The core mold control section primarily consists of a DC reduction motor 9, a bearing block 10, a spindle 11, a core mold 12, and a support 15. Support 15 is fixed to bracket 1. Two bearing blocks 10 are affixed to support spindle 11. Spindle 11 passes through the middle of the bearing blocks 10. The rear end of spindle 11 is connected to the DC reduction motor 9, while the front end is connected to core mold 12. The front end of core mold 12 is where the blank is fixed. When a command is given to the DC reduction motor 9, it provides a constant speed to the spindle 11, driving the core mold 12 at a constant speed, thereby achieving a constant speed for the blank.

[0022] The control wheel assembly primarily consists of a wheel 13, a wheel bracket 14, a support 15, and a wheel arm 8. The wheel bracket 14 is L-shaped, with one end fixed to the support 15 and rotatable around the contact point. The other end is connected to and pushed by the wheel arm 8. The wheel 13 is sheathed in the middle of the bracket 14. When the wheel arm 8 pushes the bracket 14 to rotate around the contact point, the bracket 14 drives the wheel 13, achieving spinning of the blank.

[0023] Furthermore, a guide rail 16 is fixed on the bracket, and a longitudinal stepping motor 17 is installed on the guide rail 16 so that the longitudinal stepping motor 17 can slide on the guide rail 16. The guide rail 16 supports the longitudinal stepping motor 17 and the longitudinal housing 20, thereby improving the support stiffness of the rotating wheel arm 8.
