[0002] Stainless steel wire is a metal product made of stainless steel as raw material. It has the characteristics of corrosion resistance, high temperature resistance, and high tensile strength. It is widely used in construction, machinery, shipbuilding, chemical industry, electric power and other fields. The production process of stainless steel wire requires multiple steps and is processed through drawing, wire drawing and other processes.

[0003] The existing technology mostly adopts an automatic wire bending machine disclosed in the announcement number CN104014696B, which includes a base, a cylinder, a gear rack transmission mechanism, a positioning support mechanism and a material rack. The positioning support mechanism is arranged on one side of the base, and the gear rack transmission mechanism includes two sets of gear rack pairs and a slider connecting the two sets of racks. The gear rack transmission mechanism and the material rack are fixed on the positioning support mechanism. This technology reduces production costs, improves product quality, and solves the problem of insufficient production capacity of existing manual wire bending. However, the above technology still has problems in use due to structural limitations: Existing stainless steel wires have cross-sections of circular, square and other shapes.

When the square stainless steel wire 2 moves between the two first straightening rollers 5, the two rotating first straightening rollers 5 straighten the left and right ends of the square stainless steel wire 2, so that the square stainless steel wire 2 is in a straight state, and at the same time, the square stainless steel wire 2 moves toward the second placement rack 44 until one end of the square stainless steel wire 2 is located in the second rectangular groove of the second placement rack 44, and the two first straightening motors 28 and the two second straightening motors 39 are turned off; Then start the two second drive motors 33, as shown in the attached Fig.12 and attached Fig.15 As shown, the output end of the second drive motor 33 located at the upper end of the square stainless steel wire 2 drives the upper second drive gear 34 to rotate clockwise. At the same time, since the upper third moving rack 36 and the upper fourth moving rack 37 are both meshed and driven with the upper second drive gear 34, the upper second drive gear 34 drives the upper third moving rack 36 to move upward, and the upper third moving rack 36 drives the upper second straightening roller 8 to move into the upper second installation chamber 7 through the upper second installation frame 38, and the upper second drive gear 34 drives the upper fourth moving rack 37 to move downward; As attached Fig. 22 As shown, the fourth moving rack 37 at the upper end drives the second rotating rod 43 at the upper end to move downward, and makes the second rotating rod 43 at the upper end deflect in the vertical direction, so that the second connecting sliding member 41 at the upper end slides downward in the second inclined guide groove 40 at the upper end, until the second right-angle clamping member 9 at the upper end moves out of the second installation chamber 7 at the upper end, and the second driving motor 33 at the lower end of the square stainless steel wire 2 moves the third moving rack 36 at the lower end downward, and the fourth moving rack 37 at the lower end moves upward, and makes the second straightening roller 8 at the lower end move into the second installation chamber 7 at the lower end, and the second right-angle clamping member 9 at the lower end moves out of the second installation chamber 7 at the lower end, as shown in the attached figure. Fig.15 and attached Fig.17 As shown, two second right-angle clamps 9 are used to clamp the lower left right angle and the upper right right angle of the square stainless steel wire 2 respectively; When the upper third moving rack 36 moves upward and the lower third moving rack 36 moves downward, the two third moving racks 36 respectively drive the two push rods 16 to move. Fig.15and attached Fig.17 As shown, the upper end pushes the long rod 16 to move upward and pushes the inclined plate body of the upper L-shaped clamping plate 13, and the lower end pushes the long rod 16 to move downward and pushes the inclined plate body of the lower L-shaped clamping plate 13, and the horizontal plates of the two L-shaped clamping plates 13 clamp the upper and lower ends of the square stainless steel wire 2 respectively; The two first straightening motors 28 are started to rotate the two first straightening rollers 5 so that the square stainless steel wire 2 moves toward the first placement rack 3. Fig.18 and attached Fig. 20 As shown, the moving square stainless steel wire 2 drives the vertical moving member 12 and the horizontal sliding member 11 to move toward the first placement rack 3 through the two L-shaped clamping plates 13 until the vertical moving member 12 abuts against the first placement rack 3. At this time, the weight block 18 is away from the upper end of the machine body 1 and falls down under the action of gravity, thereby tightening the connecting rope, and the connecting rope provides tension to the square stainless steel wire 2 through the two L-shaped clamping plates 13 to maintain the straight state of the square stainless steel wire 2. Then start the two first drive motors 22, as shown in the attached Figure 7 and attached Fig.18 As shown, the output end of the first driving motor 22 located on the right side of the square stainless steel wire 2 drives the first driving gear 23 at the right end to rotate clockwise. Since the first moving rack 25 at the right end and the second moving rack 26 at the right end are both meshed and driven with the first driving gear 23 at the right end, the first driving gear 23 at the right end drives the first moving rack 25 at the right end to move rightward. The first moving rack 25 at the right end drives the first straightening roller 5 at the right end to move into the first installation chamber 4 at the right end through the first installation frame 27 at the right end, and the first driving gear 23 at the right end drives the second moving rack 26 at the right end to move leftward. As attached Fig.21 As shown, the second moving rack 26 at the right end drives the first rotating rod 32 at the right end to move leftward, and makes the first rotating rod 32 at the right end deflect in the horizontal direction, so that the first connecting sliding member 30 at the right end moves leftward in the first inclined guide groove 29 at the right end, until the first right-angle clamping member 6 at the right end moves out of the first installation chamber 4 at the right end, and the first driving motor 22 located at the left end of the square stainless steel wire 2 makes the first moving rack 25 at the left end move leftward, the second moving rack 26 at the right end moves rightward, and makes the first straightening roller 5 at the left end move into the first installation chamber 4 at the left end, and the first right-angle clamping member 6 at the left end moves out of the first installation chamber 4 at the left end, as shown in the attached figure. Fig.18 and attached Fig.19 As shown, the two first right-angle clamps 6 are used to clamp the upper left right angle and the lower right right angle of the square stainless steel wire 2 respectively; When the four right angles of the square stainless steel wire 2 are in a clamped state, the bending motor 19 is started, and the output end of the bending motor 19 drives the bending cylinder 21 to rotate through the rotating disk 20, and the square stainless steel wire 2 located at the second rectangular groove is bent by rotating the bending cylinder 21.
