Description

Technical Field

[0001] The utility model belongs to the technical field of welding wire collection, and in particular relates to a first wire bending mechanism of a left pressure plate of a layer winding machine. Background Art

[0002] When the welding wire layer winding machine is winding, there is a certain tension on the welding wire. If the first wire of the welding wire is not bent, it will cause the welding wire to fall out of the first wire hole when winding the first layer of welding wire. This phenomenon is called first wire decoupling.

[0003] In order to avoid the first wire from being unhooked, the first wire is usually bent. There are currently two main ways to achieve this. One is to bend the wire outside the wire reel before inserting it into the first wire hole. This method is complex to implement and has a high cost, so it is rarely used. The other is to insert the wire into the first wire hole first, and then bend the first wire through the bending mechanism of the left pressure plate. However, the existing bending mechanism has problems such as easy failure of wire insertion, inability to bend high-strength and large-diameter wire, and easy damage to the mechanism parts. Therefore, a new first wire bending mechanism for the left pressure plate of a layer winding machine is needed. Summary of the invention

[0019] DETAILED DESCRIPTION

[0020] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific implementation methods described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present invention.

[0021] The back side of the left pressure plate 3 described in the present technical solution is the side close to the spindle box 2, and the front side of the left pressure plate 3 is the side away from the spindle box.

[0022] like Figures 1 to 8As shown, the utility model provides a left pressure plate first wire bending mechanism of a layer winding machine, comprising a spindle box 2 and a spindle 1 arranged on one side of the spindle box 2, a left pressure plate 3 is also arranged on the spindle 1, and a first driving assembly 100 which can be horizontally extended and retracted along the axial direction of the spindle 1 is also arranged on the spindle box 2, the first driving assembly 100 comprises a guide seat 10 arranged on the spindle box 2, a first cylinder 9 and a guide rod 11 are arranged on the guide seat 10, the piston rod of the first cylinder 9 is fixedly connected to the guide rod 11, and the guide rod 11 can slide back and forth in the guide seat 10 through the telescopic movement of the first cylinder 9; a second driving assembly 200 which can be extended and retracted in a horizontal direction perpendicular to the axial direction of the spindle 1 is also arranged on the guide rod 11, the second driving assembly 200 comprises a second cylinder 13 and a shifting block 14 provided with an oblique groove, the second cylinder 13 is arranged on the side of the guide rod 11, and the shifting block 14 is connected to the second The piston rod of the cylinder 13 is fixedly connected, and the extension and contraction of the second cylinder 13 can drive the shift block 14 to move horizontally; a bending block 4 is arranged on the front side of the left pressure plate 3, and a rotating pressure block 5 is rotatably arranged on the left pressure plate 3. The part of the rotating pressure block 5 located on the front side of the left pressure plate 3 is used to cooperate with the bending block 4 to bend the welding wire 15, and the part of the rotating pressure block 5 located on the back side of the left pressure plate 3 is connected with a shift rod 8. When the shift rod 8 rotates, it will drive the rotating pressure block 5 to rotate, and the other end of the shift rod 8 is provided with a round rod that can slide in the oblique groove of the shift block 14; an installation groove is also provided on the left pressure plate 3, and a spring pressure block 7 and a compression spring 6 are arranged in the installation groove. The spring pressure block 7 is used to press one end of the compression spring 6, and the other end of the compression spring 6 is pressed against the side of the rotating pressure block 5. When the rotating pressure block 5 rotates, the rotating pressure block 5 presses the compression spring 6 on the spring pressure block 7, wherein the rotating pressure block 5 and the shift rod 8 are connected by screws. When the first cylinder 9 is in a retracted state, the rotating pressure block 5 is in a clamped state by the spring force of the compression spring 6. When the first cylinder 9 is in an extended state, the lever 8 and the rotating pressure block 5 are driven to rotate by the extension and retraction of the second cylinder 13, thereby realizing the bending of the welding wire. The shapes of the rotating pressure block 5 and the bending block 4 can realize the bending of welding wires of different diameters, and make the insertion of the first wire easier. The distances from the force points of the rotating pressure block 5 and the lever 8 to the rotation center are different, forming a lever, which increases the force transmitted from the second cylinder 13 to the rotating pressure block 5, enabling it to bend high-strength welding wires.

[0023] As a better embodiment of the utility model, a positioning pin 12 is also provided at the front end of the guide rod 11. The positioning pin 12 will be inserted into the pin hole on the left pressure plate 3 when the first cylinder 9 is extended, so as to determine the position of the first thread and prevent the left pressure plate 3 from rotating under force.

[0024] It should be noted that the first wire bending work steps of this mechanism are:

[0025] S1, such as Figure 3As shown, when the first wire bending mechanism of the left pressure plate of the layer winding machine is about to start to perform the first wire bending action, the entire mechanism is in an initial state, the first cylinder 9 is in a retracted state, the second cylinder 13 is in an extended state, and the rotating pressure block 5 is in a clamped state under the action of the compression spring 6. At this time, the plastic welding wire reel 17 is installed on the main shaft 1.

[0026] S2, such as Figure 4 As shown, after the action starts, the first cylinder 9 extends out, the positioning pin 12 is inserted into the pin hole in the left pressure plate 3, and the cylinder of the shift rod 8 is inserted into the inclined groove of the shift block 14, and the entire mechanism is in a ready state.

[0027] S3, such as Figure 5 As shown, the second cylinder 13 retracts, the shifting block 14 moves, and drives the shifting rod 8 to rotate clockwise. Because the rotating pressing block 5 and the shifting rod 8 are fixed together, the rotating pressing block 4 rotates clockwise at a certain angle at the same time, and is now in an open state, and the force of the second cylinder 13 acting on the rotating pressing block 5 is greater than the spring force acting on it. The welding wire 15 is horizontally inserted from the first wire hole 17 of the welding wire reel to between the rotating pressing block 5 and the bending block 4, and the entire mechanism is now in an open state.

[0028] S4, such as Figure 6 As shown, the second cylinder 13 then extends, and the movement of the shifting block 14 drives the shifting rod 8 to rotate counterclockwise, and the rotating pressing block 5 also rotates counterclockwise, and the mechanism is in a clamped state. Since the rotating pressing block 5 and the bending block 4 are equivalent to a male and female die structure, the welding wire will bend in it. The compression spring 6 will also support the rotating pressing block 5 to provide a certain bending force.

[0029] S5, the first cylinder 9 retracts, the shifting block 14 is separated from the shifting rod 8, and the welding wire 15 is also pressed by the rotating pressing block 5 supported by the compression spring 6, and the wire winding can begin.

[0030] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions and substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
