Embodiment 1

[0020] A curved blade cold stamping die 5 (hereinafter referred to as: blade stamping die), including blade upper mold 12, blade lower mold 13; Improve the arc surface blade 30, and optimize the design of the blade stamping die; the blade stamping die 5 cooperates with the arc surface blade cold stamping forming machine, and the arc surface blade 30 is stamped and formed at one time, the production efficiency is high, and the blade quality is excellent. Guarantee; the fluid resistance generated by the arcuate blade 30 is small, and can generate axial flow; the specific implementation is described in detail as follows.

[0021] The blade upper mold 12 includes a mold disk 14, mold vertical ribs 16, upper mold convex arc 17, and upper mold top plate; the mold disk 14 is a mold disk corresponding to the stamping disk 11 of the stamping cylinder 2 14. It has a mounting hole connected to the stamping disc 11; the mold vertical rib 16 is a plurality of mold vertical reinforcement ri...

Embodiment 2

[0026]A stamped mixer arc blade 30 (referred to as arc blade), including an arc segment 31 and a flat segment 32, the flat segment 32 has a mounting hole 33, and the tip is narrow , the blade arc surface section 31 uses the arc surface blade cold stamping forming die 5 provided by the present invention (abbreviation: blade stamping die), the blade stamping die 5 and the arc surface blade cold stamping forming machine (abbreviation: stamping forming machine ) to form the arc-shaped paddle 30 by stamping at one time; the arc-surface paddle 30 produces less fluid resistance and can generate axial flow, which is suitable for the paddle of the flocculation mixer. Now, the stamping and forming process of the arcuate blade 30 and the equipment used are described as follows.

[0027] The curved surface blade uses a stamping forming machine, which is mainly composed of a stamping mechanism, a double-column frame, and a control cabinet 7; the stamping mechanism includes a hydraulic pump...

Abstract

The invention discloses a cold stamping forming die for a cambered-surface paddle and a stirrer cambered-surface paddle stamped and formed by the same. The cold stamping forming die comprises an upper paddle die and a lower paddle die. The key points of the innovative scheme are as follows: a plane paddle of the flocculation stirrer is improved into a cambered-surface paddle, and the paddle stamping die is optimally designed and comprises an upper die connecting disc, a lower die positioning plate, an upper die convex arc and a lower die concave arc; the paddle stamping die is matched with the cold stamping forming machine, the upper paddle die is installed below a stamping disc of a stamping oil cylinder, the lower paddle die is arranged in the middle of a die platform, the cambered-surface paddle is formed through one-time stamping, the production efficiency is high, the paddle quality is guaranteed, the fluid resistance generated by the cambered-surface paddles is small, and axial flow can be generated; the cambered-surface paddle of a stirrer comprises a paddle cambered surface section, a paddle plane section and a paddle mounting hole; the technical problems that a plane paddle cannot generate axial flow, the stirring effect is poor, the fluid resistance generated by the plane paddle is large, and the stirring efficiency is low are solved; and the paddle is suitable for the flocculation stirrer.

Description

technical field [0001] The invention belongs to the technical field of cold stamping forming machines and mixers, and relates to an arc-shaped blade of a flocculation mixer and a cold stamping forming mold thereof. Background technique [0002] Cold stamping forming machine is a kind of processing and forming equipment with little cutting or no cutting; the cold stamping forming machine cooperates with the die to apply pressure to the material at room temperature to separate or produce plastic deformation to obtain products of a certain shape and size; Mainly composed of stamping mechanism, double-column frame, control cabinet; stamping mechanism, including hydraulic pump station, stamping oil cylinder; double-column frame, including oil cylinder seat, frame column, mold platform, pedestal stabilization plate, pump station side bracket; The cold stamping forming machine is used in conjunction with the arc blade stamping die, which has the function of stamping and forming the...
