Description

Technical Field

[0001] The invention belongs to the technical field of bending and forming, and particularly relates to a wire bending and forming machine and a working method thereof. Background Art

[0002] Wire bending equipment is mainly used for processing or pre-processing wire materials such as steel wire and iron wire. It can straighten coiled and bent wire materials and bend straight wire materials to achieve a predetermined bending effect. Traditional wire bending machines divide the workpiece mold into two halves, the lower half of which is fixed on the workbench table and the upper half is set directly above the lower half. When bending the wire, the workpiece to be bent is placed on the lower half of the mold, and then the upper half of the mold is driven by the cylinder to align with the lower half of the mold to bend the workpiece into shape. When bending the wire, one end of the wire is abutted against the abutment plate, and then the operating device is directly rotated. The abutment frame and the mounting frame are slidingly arranged to complete the bending action. However, during the conveying process of the wire, the wire cannot be properly conveyed in a straight state. At the same time, the corresponding equipment is simple and cannot perform a continuous bending action on the wire, resulting in an inability to perform a continuous bending process of the wire, thereby affecting the continuous bending process of the wire and reducing the efficiency.

[0063] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0064] Example 1

[0065] This embodiment 1 provides a forming machine, comprising: a workbench 1; a rotary straightening mechanism 2000, a wire feeding mechanism 3000, a first forming mechanism 4000, and a rotary translation mechanism 5000, which are sequentially arranged on the workbench 1000; the rotary straightening mechanism 2000 is adapted to align a straightened wire 9000; the wire feeding mechanism 3000 is adapted to feed the straightened wire 9000 into the first forming mechanism 4000; the first forming mechanism 4000 is adapted to perform an initial bending and cutting of the wire 9000; The rotating and translating mechanism 5000 is suitable for rotating the wire 9000 after the initial bending; the robotic arm 6000 is located above the workbench 1000 to transport the wire 9000 after the rotation angle to the pressing and turning mechanism 7000; the pressing and turning mechanism 7000 is located below the workbench 1000 to clamp the wire 9000 after the rotation angle; and the second forming mechanism 8000 is located below the workbench 1000 to bend and form the wire 9000 after the rotation angle again.

[0066] Optionally, the rotary straightening mechanism 2000, the wire feeding mechanism 3000, and the first forming mechanism 4000 are located on the same straight line to ensure that the wire 9000 can maintain good linearity during the straightening and conveying process. In this case, the first forming mechanism is a conventional bending and forming mechanism, which generally drives the bending head to rotate through the output shaft of the motor to bend the wire into shape, or a bending and forming device of a wire forming machine disclosed in Patent No. CN201721163291.1, which is suitable for bending wires (such as steel wires).

[0067] As an optional implementation of the compression line transfer mechanism.

[0068] See Figure 2-13 The pressing and turning mechanism 7000 includes: a pressing module 7100 for pressing the wire 9000 radially; and a turning module 7200 which is arranged opposite to the pressing module 7100 to rotate the wire 9000 at an angle.

[0069] See Figures 6-10 The wire pressing module 7100 includes: a wire pressing motor 7110; a wire pressing gear 7120, which is driven to rotate by the wire pressing motor 7110; a clamping shaft 7130, which is located inside the wire pressing gear 7120; an eccentric portion 7121 is provided on the inner side of the wire pressing gear 7120, which periodically drives the clamping shaft 7130 to press the wire 9000 downward when rotating.

[0070] See Figure 2 、 Figure 8 and Figure 9 The upper end of the pressing shaft 7130 is provided with a pressing pin 7140, and the lower end of the pressing shaft 7130 is provided with a pressing portion 7131. The pressing portion 7131 is concavely arc-shaped and conforms to the outer contour of the wire rod. The top of the pressing pin 7140 is convexly arc-shaped to reduce friction on the inner side of the wire pressing gear 7120 and facilitate the movement of the eccentric portion to the top of the pressing pin 7140, causing the pressing pin 7140 to press down on the pressing shaft 7130.

[0071] See Figure 2 、 Figure 11 and Figure 12 The wire rotating module 7200 includes: a wire rotating motor 7210; a wire rotating gear 7220, which is fixed on the wire pressing gear 7120; the wire rotating motor 7210 is suitable for driving the wire rotating gear 7220 to rotate, so as to drive the wire pressing gear 7120 to rotate synchronously through the wire rotating gear 7220.

[0072] Further, see Figure 7 、 Figure 12, the wire turning gear 7220 and the wire pressing gear 7120 are both provided with corresponding wire clamping holes 7300; the two wire clamping holes 7300 are located at the same horizontal height to clamp the wire 9000. The wire clamping hole 7300 is a flared hole, and its upper hole wall is slightly inclined upward to be suitable for spitting out or swallowing wire. Specifically, the interior of the wire turning gear and the wire pressing gear are both hollow to accommodate the passage of wire. The wire turning gear 7220 is approximately concave in shape, and a through hole 7221 is provided on its upper surface to accommodate the pressing shaft to enter the interior of the wire turning gear and compress the wire.

[0073] The compression and wire-turning mechanism of this embodiment compresses the wire radially through the wire-pressing module, and then rotates the wire at an angle through the wire-turning module for re-forming, thereby realizing a continuous process of multiple bending of the wire and improving production efficiency.

[0074] As an optional implementation of the rotation and translation mechanism.

[0075] See Figures 14-22 The rotation and translation mechanism 5000 includes: a translation module 5100, which is slidably installed on the workbench 1000; a rotation clamping module 5200, which is located on the translation module 5100 and is arranged close to the wire feeding mechanism 3000 to clamp one end of the wire 9000; the translation module 5100 is suitable for driving the rotation clamping module 5200 to move, so that the rotation clamping module 5200 clamps one end of the wire 9000 and pulls the wire 9000 to translate along the workbench.

[0076] See Figure 14 and Figure 18 The translation module 5100 includes: a linear guide rail 5110, which is laid on the workbench 1000; a linear slide 5120, which is located on the linear guide rail 5110; and a translation motor 5130, which drives the linear slide 5120 to move along the linear guide rail 5110 through a screw rod.

[0077] Optionally, the translation motor is, for example but not limited to, a servo motor. When the rotary clamping module clamps one end of the wire, the linear slide 5120 is driven by the screw rod to move along the linear guide rail 5110, thereby driving the rotary clamping module to move, and the wire is translated to a specified position, and then rotated a certain angle by the rotary clamping module, which can be used for secondary bending and forming needs.

[0078] See Figure 14 , Figures 17-22 The rotary clamping module 5200 includes: a rotary cylinder seat 5210, mounted on the linear slide 5120; a rotary cylinder 5220, mounted on the rotary cylinder seat 5210, for rotating the wire 9000; and a rotary chuck 5230, located on the rotary cylinder 5220, for clamping one end of the wire 9000.

[0079] Optionally, the rotary cylinder seat 5210 is adapted to be fixedly mounted on the rotary cylinder 5220 via a cylinder fixing bracket 5240. Optionally, the rotary chuck 5230 is a conventional device that only needs to achieve the function of clamping the wire, such as a clamping block.

[0080] In this case, both the translation module 5100 and the rotary clamping module 5200 can be mounted on a translation base plate 5310, which is mounted on a linear guide rail 5110 via a plurality of sliders 5320. By manually adjusting the position of the translation base plate, the horizontal displacement of the entire rotary translation mechanism can be controlled to adjust the cutting distance of the wire after initial forming, making it suitable for bending wires of different lengths.

[0081] The rotary translation mechanism of this embodiment clamps one end of the wire through the rotary clamping module after the initial forming, and drives the rotary clamping module to move through the translation module to pull the wire to translate along the workbench. The position and angle of the wire can be changed to meet the requirements of the second forming, thereby realizing the continuous bending process of the forming machine.

Specifically, the adjustment blocks are arranged in multiple groups, which can be divided into middle adjustment blocks and end adjustment blocks to drive the movement of the straightening blocks. The end adjustment blocks have a similar structure to the middle adjustment blocks.

[0087] For details, see Figure 25-28 The adjusting block 2131 is provided with an adjusting screw 2133, which can be used to adjust the distance between the two relatively arranged adjusting blocks, and then adjust the internal space of the straightening block 2132 to adapt to wires of different diameters. Of course, the straightening effect of the wire can also be adjusted in this way.
