Description

Technical Field

[0001] This utility model relates to the field of cold heading machine technology, and in particular to an automatic feeding device for cold heading machines. Background Technology

[0002] A cold heading machine is a specialized piece of equipment for metal processing, capable of mass-producing fasteners such as nuts and bolts. The cold heading machine uses steel wire as its main raw material, and the steel wire is driven into the interior of the cold heading machine by a feeding device.

[0003] In existing cold heading machines, the feeding device uses upper and lower rollers to clamp the steel wire through friction. When the rollers rotate, the steel wire moves forward due to friction. However, the distance between the upper and lower rollers is fixed. When feeding steel wires of different widths, rollers with different spacing need to be replaced, which is inconvenient for workers. Utility Model Content

[0004] This utility model proposes an automatic feeding device for cold heading machines to overcome the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic feeding device for a cold heading machine, including a worktable, the worktable being placed on the ground with the aid of support legs to provide overall support, a bracket being fixedly connected to the upper surface of the worktable, two rollers being rotatably connected to the same side of the bracket, a drive mechanism being installed on the other side of the bracket, wherein the drive mechanism can drive the two rollers to rotate, and a pushing device being disposed on the arc surface of the rollers, the pushing device being able to push steel wires of different widths forward.

[0006] The effect achieved by the above components is as follows: when it is necessary to feed steel wire, the worker places the steel wire between the two rollers, then turns on the drive mechanism, which drives the two rollers to rotate. The rollers clamp the steel wire through friction and drive the steel wire to move forward, thereby completing the feeding of the steel wire.

[0007] Preferably, the pushing device includes a plurality of grooves, which are evenly distributed on the arc surface of the roller and are circumferentially distributed. The roller is fixedly connected to a spring via the grooves, and one end of the spring is fixedly connected to a movable plate, wherein the size of the movable plate is adapted to the size of the grooves. The rubber pad is detachably installed on one side of the movable plate with the aid of an auxiliary device, wherein the size of the rubber pad is adapted to the size of the movable plate.

[0008] The effect achieved by the above components is as follows: When the rollers rotate, the movable plate on the rollers rotates with the rollers. When the movable plate moves to the position of the steel wire, the steel wire squeezes the movable plate on the upper and lower rollers, causing the movable plate to move inward toward the groove. The spring deforms, and at this time, the spring will give the movable plate a spring force toward the steel wire. The movable plate is in close contact with the steel wire with the help of the rubber pad. Friction is generated between the rubber pad and the steel wire, which drives the steel wire forward. As the rollers continue to rotate, the movable plate in front will gradually move away from the steel wire. Under the action of the spring's return force, the movable plate in front moves back to its original position, and the next movable plate will then come into contact with the steel wire, thus completing the continuous feeding of the steel wire. When feeding steel wires of different widths, the depth of the movable plate into the groove will change accordingly. The feeding of the steel wire can be completed without adjusting the distance between the two rollers. The pushing device achieves the effect of feeding steel wires of different widths, thereby improving the practicality of the feeding device.

[0009] Preferably, a plurality of rubber cones are fixedly connected to the upper surface of the rubber pad, and the plurality of rubber pads are arranged in a matrix.

[0010] The effect achieved by the above components is as follows: when the steel wire comes into contact with the rubber cone on the rubber pad, the tip of the rubber cone will be squeezed and deformed by the steel wire. At this time, the rubber cones on both sides of the steel wire that are not squeezed will limit the steel wire, prevent the steel wire from moving to both sides, and improve the stability of the steel wire movement.

[0011] Preferably, both ends of the movable plate are fixedly connected to sliders, and a groove is formed inside the groove corresponding to the slider, wherein the size of the slider is adapted to the size of the groove.

[0012] The effect achieved by the above components is that by moving the slider of the moving plate in the groove of the groove, the direction of movement of the moving plate is restricted, thus preventing the moving plate from shaking.

[0013] Preferably, the upper surface of the workbench is fixedly connected to two positioning tubes by means of a support rod, wherein the two positioning tubes are located on both sides of the roller.

[0014] The effect achieved by the above components is that by setting the positioning tube, the movement direction of the steel wire is initially limited, making it easier for the steel wire to enter between the two rollers.

[0015] Preferably, an auxiliary device is included, which is disposed on both sides of the rubber pad. The auxiliary device includes two fixed plates, which are respectively fixedly connected to both ends of the rubber pad. Insert plates are slidably disposed on the surface of the fixed plates, wherein the insert plates are iron plates. The movable plate has an insertion hole corresponding to the insertion plate, wherein a magnet is installed inside the insertion hole.

[0016] The aforementioned components achieve the following effect: When the rubber pad needs to be installed, the worker moves the rubber pad, and the rubber pad adheres to the surface of the moving plate. Then, the worker moves the insert plate, and the insert plate passes through the fixed plate and is inserted into the socket of the moving plate. The magnet inside the socket attracts the iron insert plate, and finally the insert plate adheres to the magnet in the socket, achieving the effect of fixing the insert plate. When the rubber pad ages and needs to be replaced, the worker moves the insert plate, and the insert plate is removed from the socket of the moving plate. Then, the worker can take out the aged rubber pad. The auxiliary device achieves the effect of fixing the rubber pad, and at the same time, the worker replaces the rubber pad when it ages.

[0017] Preferably, each of the four corners of the bottom of the rubber pad is fixedly connected with a positioning rod, and the movable plate is provided with a positioning hole corresponding to the positioning rod, wherein the size of the positioning rod is adapted to the size of the positioning hole.

[0018] The effect achieved by the above components is that by inserting the positioning rod of the rubber pad into the positioning hole of the moving plate, the rubber pad is limited, thus preventing the rubber pad from shaking.

[0019] Preferably, one end of the positioning rod is fixedly connected to a pointed protrusion, wherein the tip of the pointed protrusion is far away from the positioning rod.

[0020] The effect achieved by the above-mentioned components is that the pointed protrusions make it easier for workers to insert the positioning rod into the positioning hole of the moving plate, thus providing convenience for workers.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] As the rollers rotate, the movable plate on the rollers rotates along with them. When the movable plate moves to the position of the steel wire, the steel wire presses against the movable plate on the upper and lower rollers, causing the movable plate to move inward toward the groove. The spring deforms, and at this time, the spring gives the movable plate a spring force toward the steel wire. The movable plate is pressed tightly against the steel wire with the help of the rubber pad, and friction is generated between the rubber pad and the steel wire. This friction force drives the steel wire forward. As the rollers continue to rotate, the movable plate in front will gradually move away from the steel wire. Under the action of the spring's return force, the movable plate in front moves back to its original position, and the next movable plate will then come into contact with the steel wire, thus completing the continuous feeding of the steel wire. When feeding steel wires of different widths, the depth of the movable plate into the groove will change accordingly. The feeding of steel wires can be completed without adjusting the distance between the two rollers. The pushing device achieves the effect of feeding steel wires of different widths, thereby improving the practicality of the feeding device. Attached Figure Description

[0029] Reference Figure 1-5 As shown, this embodiment discloses an automatic feeding device for a cold heading machine, including a worktable 1. The worktable 1 is supported by legs placed on the ground, and a bracket 2 is fixedly connected to the upper surface of the worktable 1. Two rollers 3 are rotatably connected to the same side of the bracket 2, and a drive mechanism 4 is installed on the other side of the bracket 2. The drive mechanism 4 can drive the two rollers 3 to rotate. A pushing device 6 is disposed on the arc surface of the rollers 3 and can push steel wires of different widths forward. When it is necessary to feed the steel wire, the operator places the steel wire between the two rollers 3, and then opens the drive mechanism 4. The drive mechanism 4 drives the two rollers 3 to rotate. The rollers 3 clamp the steel wire through friction and drive the steel wire forward, thereby completing the feeding of the steel wire.

[0030] Reference Figure 1-5As shown, the pushing device 6 includes several grooves 61, which are evenly distributed on the arc surface of the roller 3. The grooves 61 are circumferentially distributed. The roller 3 is fixedly connected to a spring 62 via the grooves 61. One end of the spring 62 is fixedly connected to a movable plate 63, wherein the size of the movable plate 63 is adapted to the size of the groove 61. A rubber pad 64 is detachably installed on one side of the movable plate 63 with the aid of an auxiliary device 7, wherein the size of the rubber pad 64 is adapted to the size of the movable plate 63. As roller 3 rotates, the movable plate 63 on roller 3 rotates along with roller 3. When the movable plate 63 moves to the position of the steel wire, the steel wire squeezes the movable plate 63 on the upper and lower rollers 3, causing the movable plate 63 to move inward toward the groove 61. The spring 62 deforms, and at this time, the spring 62 will give the movable plate 63 a spring force toward the steel wire. The movable plate 63 is in close contact with the steel wire with the help of the rubber pad 64. Friction is generated between the rubber pad 64 and the steel wire, and this friction can drive the steel wire to move forward. As roller 3 continues to rotate, the front... The moving plate 63 will gradually move away from the steel wire. Under the action of the spring 62's return force, the moving plate 63 in front will move back to its original position, and the next moving plate 63 will follow and contact the steel wire, thus completing the continuous feeding of the steel wire. When feeding steel wires of different widths, the depth of the moving plate 63 into the groove 61 will change accordingly. The feeding of the steel wire can be completed without adjusting the distance between the two rollers 3. The pushing device 6 achieves the effect of feeding steel wires of different widths, thereby improving the practicality of the feeding device.

[0031] Reference Figure 1-5 As shown, several rubber cones 67 are fixedly connected to the upper surface of the rubber pad 64, and the rubber pads 64 are arranged in a matrix. When the steel wire comes into contact with the rubber cones 67 on the rubber pad 64, the tip of the rubber cone 67 is squeezed and deformed by the steel wire. At this time, the rubber cones 67 on both sides of the steel wire that are not squeezed will limit the steel wire, preventing the steel wire from moving to the sides and improving the stability of the steel wire movement. Both ends of the moving plate 63 are fixedly connected to sliders 65, and grooves 66 are opened inside the groove 61 corresponding to the sliders 65, wherein the size of the sliders 65 and the size of the grooves 66 are adapted to each other. By moving the sliders 65 of the moving plate 63 in the grooves 66 of the groove 61, the movement direction of the moving plate 63 is limited, and the moving plate 63 is prevented from shaking. The upper surface of the worktable 1 is fixedly connected to two positioning tubes 5 by means of a support rod, and the two positioning tubes 5 are located on both sides of the roller 3. By setting the positioning tubes 5, the movement direction of the steel wire is initially limited, which facilitates the steel wire to enter between the two rollers 3.

[0032] Reference Figure 1-5As shown, the auxiliary device 7 is set on both sides of the rubber pad 64. The auxiliary device 7 includes two fixing plates 71, which are fixedly connected to the two ends of the rubber pad 64 respectively. The surface of the fixing plate 71 is slidably provided with an insert plate 72, wherein the insert plate 72 is an iron plate. The movable plate 63 has an insertion hole 73 corresponding to the insert plate 72, wherein a magnet is installed inside the insertion hole 73. When the rubber pad 64 needs to be installed, the worker moves the rubber pad 64 until it adheres to the surface of the moving plate 63. Then, the worker moves the insert plate 72, which passes through the fixing plate 71 and is inserted into the socket 73 of the moving plate 63. The magnet inside the socket 73 attracts the iron insert plate 72, and finally, the insert plate 72 adheres to the magnet in the socket 73, thus achieving the effect of fixing the insert plate 72. When the rubber pad 64 ages and needs to be replaced, the worker moves the insert plate 72, which is removed from the socket 73 of the moving plate 63. Then, the worker can remove the aged rubber pad 64. The auxiliary device 7 achieves the effect of fixing the rubber pad 64, and the worker can replace the rubber pad 64 when it ages.

[0033] Reference Figure 1-5 As shown, positioning rods 74 are fixedly connected to the four corners of the bottom of the rubber pad 64. Positioning holes 75 are provided on the moving plate 63 corresponding to the positioning rods 74, with the dimensions of the positioning rods 74 matching the dimensions of the positioning holes 75. By inserting the positioning rods 74 of the rubber pad 64 into the positioning holes 75 of the moving plate 63, the rubber pad 64 is effectively limited, preventing it from shaking. A pointed protrusion 76 is fixedly connected to one end of the positioning rod 74, with the tip of the protrusion 76 away from the positioning rod 74. The pointed protrusion 76 facilitates the insertion of the positioning rod 74 into the positioning holes 75 of the moving plate 63, providing convenience for the operator.

[0034] Working principle: When steel wire needs to be fed, the operator places the steel wire between the two rollers 3 through the positioning tube 5. Then, the drive mechanism 4 is turned on, and the drive mechanism 4 drives the two rollers 3 to rotate. The moving plate 63 on the rollers 3 will rotate with the rollers 3. When the moving plate 63 moves to the position of the steel wire, the steel wire squeezes the moving plate 63 on the upper and lower rollers 3. The moving plate 63 moves inward towards the groove 61. The slider 65 of the moving plate 63 moves in the groove 66 of the groove 61, which achieves the effect of restricting the movement direction of the moving plate 63. The spring 62 deforms. At this time, the spring 62 will give the moving plate 63 a spring force in the direction of the steel wire. The moving plate 63 is in close contact with the steel wire with the help of the rubber pad 64. The tip of the rubber cone 67 on the rubber pad 64 will be deformed by the pressure of the steel wire. At this time, the rubber cones 67 on both sides of the steel wire that are not squeezed will limit the steel wire and prevent it from moving to the sides. Friction will be generated between the rubber pad 64 and the steel wire. This friction will drive the steel wire forward. As the roller 3 rotates continuously, the front moving plate 63 will gradually move away from the steel wire. Under the action of the spring 62's return force, the front moving plate 63 will move back to its original position, and the next moving plate 63 will follow and contact the steel wire, thus completing the continuous feeding of the steel wire. When feeding steel wires of different widths, the depth of the moving plate 63 into the groove 61 will change accordingly. The feeding of the steel wire can be completed without adjusting the distance between the two rollers 3. By pushing the device 6, the effect of feeding steel wires of different widths is achieved, thereby improving the practicality of the feeding device.

[0035] When the rubber pad 64 needs to be installed, the worker moves the rubber pad 64, and the positioning rod 74 on the rubber pad 64 is inserted into the positioning hole 75 of the moving plate 63 by means of the pointed protrusion 76, which limits the rubber pad 64. Finally, the rubber pad 64 is attached to the surface of the moving plate 63. Then the worker moves the insert plate 72, and the insert plate 72 passes through the fixing plate 71 and is inserted into the insertion hole 73 of the moving plate 63. The magnet inside the insertion hole 73 attracts the iron insert plate 72, and finally the insert plate 72 is attached to the magnet in the insertion hole 73, which achieves the effect of fixing the insert plate 72. When the rubber pad 64 is old and needs to be replaced, the worker moves the insert plate 72 and removes it from the insertion hole 73 of the moving plate 63. Then the worker can take out the old rubber pad 64. The auxiliary device 7 achieves the effect of fixing the rubber pad 64. At the same time, when the rubber pad 64 is old, the worker replaces the rubber pad 64.
