Description

Technical Field

[0001] The utility model relates to the technical field of steel belt ring forming equipment, in particular to a crimping mechanism for steel belt ring forming. Background Art

[0002] The processing of steel belt rings includes feeding, cutting, welding and other processes. They can be automatically welded and formed by welding equipment. When the steel belt ring is used to make the bottom of a barrel, etc., one end of the steel belt ring needs to be pressed by a pressing mechanism. The applicant has previously applied for an invention patent for a coaxial cam dual-drive edge pressing mechanism for steel strip ring forming (publication number: CN116037736A), which discloses a method for pressing the steel strip ring. The steel strip ring can be clamped by a supporting wheel and a pressure wheel, and then the outer edge of the steel strip ring is pressed by the edge pressing wheel. It is convenient and stable. However, this edge pressing method can only press the bottom of the steel strip ring into an "L" shape in cross section. When a cardboard ring is attached to the steel strip ring, the bottom of the steel strip ring needs to be curled and pressed into a hook shape to hook the bottom of the cardboard ring. The above-mentioned edge pressing mechanism cannot roll out the above-mentioned hook shape and can only use the traditional axial curling method. During operation, the straight edge of the steel strip ring will deviate as a whole along the curling groove of the curling wheel instead of curling, until the straight edge of the steel strip ring reaches the deepest part of the curling groove and begins to be directly subjected to the pressing force of the curling wheel, which easily causes the steel strip ring to bend as a whole and the curling stability is poor. Utility Model Content

[0003] The purpose of the utility model is to avoid the deficiencies of the prior art and provide a crimping mechanism for forming a steel belt ring, thereby effectively solving the deficiencies in the prior art.

[0005] Furthermore, a slide is provided on the support frame, a slide rod is movably provided on the slide, a mounting seat is fixedly provided on the slide rod, and the curling wheel is horizontally rotatably provided on the mounting seat.

[0006] Furthermore, the curling wheel is detachably arranged on the mounting seat.

[0007] Furthermore, a U-shaped seat is vertically rotatably provided on the mounting seat, the curling wheel is rotatably provided on the U-shaped seat, and two curling grooves with different curvatures are circumferentially provided on the curling wheel.

[0008] Furthermore, a positioning plate is movably provided at the bottom of the mounting seat, and positioning grooves are provided on both the upper and lower sides of the U-shaped seat to cooperate with the positioning plate.

[0009] Furthermore, the positioning plate is matched with the mounting seat through a T-shaped slot, and an elastic member is provided on the rear side of the positioning plate.

[0010] Furthermore, the upper and lower sides of the U-shaped seat are configured as semicircular grooves to match the rotating shaft of the curling wheel, and a fixing plate is fixed on the U-shaped seat to the outer side of the rotating shaft of the curling wheel by bolts.

[0011] The above technical solution of the present invention has the following beneficial effects: the present invention can first clamp the steel belt ring by the supporting wheel and the pressure wheel, then press the outer edge of the steel belt ring into an L shape by the pressure wheel, and then curl it by the curling wheel, so as to avoid the straight edge of the steel belt ring directly hitting the deepest part of the curling groove of the curling wheel, making it convenient for the edge of the steel belt ring to curl along the curling groove, and clamping the steel belt ring by the supporting wheel and the pressure wheel, thereby further improving the stability of the curling and improving the yield rate.
