Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and the embodiments thereof.

[0015] like figure 1 , figure 2 , image 3 and Figure 4 As shown, put the workpiece into the machine and drive the crimping die to rotate 270 degrees and then stop. The rocker cylinder advances to drive the upper die to rotate and hold the pressure for 2 seconds. The rocker cylinder retreats, the pressing upper mold is released and returns to its position, the fork cylinder advances and the rolling mold is moved back, so that the workpiece is separated from the rolling mold and the workpiece is taken out. The crimping die rotates 90 degrees and returns to its position, the fork oil cylinder retreats, the crimping die protrudes, and then the second workpiece is processed.

[0016] The motor 14 drives the gearbox 16 to rotate the gear shaft 6 through the gear set 5, and the gear shaft 6 drives the curling shaft 7 to rotate thr...

Abstract

The invention discloses an S-shape harrow cutter bent arc forming machine, comprising a motor and a transmission mechanism. The S-shape harrow cutter bent arc forming machine is characterized by further comprising a curling die, a profiling upper die and a profiling lower die, wherein the curling die rotates for 270 degrees to enable one end of a workpiece to form a spiral shape of specified size, and the profiling upper die rotates to close with the profiling lower die to shape the other end of the workpiece. Via organic combination of hydraulic transmission and mechanical transmission, the workpiece is shaped at a time in multiple steps, the problem of low qualification ratio under first acceptance check of the processed products in multiple steps is thoroughly solved, and the international market competitiveness of products is improved. By using a ratchet wheel and a pawl automatic stop device, accuracy of position of the curling die under the outer force is ensured.

Description

technical field [0001] The invention relates to an arc bending machine, in particular to an arc bending forming machine special for S-shaped rake knives. Background technique [0002] At present, the pipe fitting arc bending machines sold or used in the market generally adopt the bending method of ordinary rollers, which not only consumes manpower, but also cannot achieve wide applicability and accuracy in terms of the quality of the bent pipe fittings. The disadvantage of poor precision, and the S-type rake cannot be formed at one time. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a special arc forming machine for S-shaped rake knives. [0004] In order to solve the technical problem, the technical solution adopted by the present invention is: an S-type rake knife bending arc forming machine, including a motor and a transmission mechanism, and is characterized in ...
