Description

Technical Field

[0001] This utility model relates to the field of bar and wire production technology, and in particular to a fixed-length shearing device for bar and wire production. Background Technology

[0002] Bars and wires are divided into ordinary bars and wires and special steel bars and wires, with specifications of 9-50mm, 50-100mm, and 100-300mm; wires are divided into coils and special wires, with specifications of 5-10mm. Bars and wires have small cross-sections and large lengths, and require high dimensional accuracy and surface quality. During the production of bars and wires, shearing devices are required to cut them.

[0003] Most existing bar and wire shearing devices cut bars and wires to length by moving a baffle. However, during the length cutting process, in order to ensure close contact between the bar and wire and the baffle, the bar and wire continues to move even after contact, resulting in significant pressure on the baffle. Since the baffle is adjustable, the connection between the baffle and the connecting seat is prone to loosening. Over time, this leads to poor length cutting accuracy and affects the shearing precision of the bar and wire. Therefore, these devices are not suitable for length cutting and cannot meet customer needs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. Most existing bar and wire shearing devices measure the length of bar and wire by moving a baffle. However, during this process, to ensure close contact between the bar and wire and the baffle, the bar and wire continue to move even after contact, resulting in significant pressure on the baffle. Furthermore, because the baffle is adjustable, the connection between the baffle and the connecting seat is prone to loosening. Over time, this leads to poor accuracy in baffle length measurement, affecting the shearing precision of the bar and wire.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed-length shearing device for bar and wire production, comprising a concave plate, a rotating drum embedded in the top of the concave plate, the outer surface of the rotating drum being rotatably connected to the concave plate via a bearing, a driven gear being fixedly connected to the top of the outer surface of the rotating drum, a servo motor being fixedly connected to the right side of the top of the concave plate, a driving gear being fixedly connected to the output end of the servo motor, the driving gear and the driven gear meshing, a stud being threadedly connected to the inner surface of the rotating drum, the bottom of the stud penetrating the rotating drum and being fixedly connected to a lifting plate, slide rails being fixedly connected to the front and rear positions of the bottom of the lifting plate, slide plates being slidably connected to the outer surfaces of the front and rear slide rails, limit bolts being threadedly connected to the left and right sides of the front of the slide plate, the back of the limit bolts penetrating the slide plate and tightly fitting with the connection of the slide rails, a vertical plate being fixedly connected to the bottom of the slide plate, a rotary motor being fixedly installed on the right side of the vertical plate, the output end of the rotary motor penetrating the vertical plate and being fixedly installed with a cutting disc by screws, and limit components being provided on the left and right sides of the bottom of the slide plate.

The back of the slide plate 9 is connected to the slide rail 8. The bottom of the slide plate 9 is fixedly connected to the vertical plate 11. The right side of the vertical plate 11 is fixedly installed with the rotary motor 12. The output end of the rotary motor 12 passes through the vertical plate 11 and is fixedly installed with the cutting disc 13 by screws. Limiting components 14 are provided on both the left and right sides of the bottom of the slide plate 9. The front of the lifting plate 7 is fixedly connected to the scale 16. The front of the slide plate 9 is fixedly connected to the indicator arrow 17 that works with the scale 16 and the cutting disc 13. The top of the lifting plate 7 is fixedly connected to the left and right sides of the top. The top of the guide rod 18 passes through the concave plate 1 and extends to the top of the concave plate 1. The top of the concave plate 1 is embedded in the left and right sides of the top. The inner surface of the slide cylinder 19 is slidably connected to the outer surface of the guide rod 18.

[0024] In this embodiment: By setting up a lifting plate 7, a slide rail 8, a sliding plate 9, a limiting bolt 10, a vertical plate 11, a rotary motor 12, and a cutting disc 13, the cutting position of the cutting disc 13 can be adjusted to a fixed length.

By setting up the above structure, the bar wire can be conveniently cut to a fixed length, thereby meeting the customer's usage needs and avoiding affecting the cutting accuracy of the bar wire.

[0025] Example 2

[0026] Figure 1 , Figure 2 and Figure 3The limiting component 14 includes a positioning box 141. A convex plate 142 is slidably connected to the inner surface of the positioning box 141. A counterweight plate 143 is fixedly connected to the bottom of the convex plate 142 through the positioning box 141. A rubber pad is fixedly connected to the bottom of the counterweight plate 143. The top of the positioning box 141 is fixedly connected to the connection point of the slide plate 9. Slide tracks 15 that cooperate with the convex plate 142 are provided on both the left and right sides of the inner cavity of the positioning box 141. The inner surface of the slide track 15 is slidably connected to the outer surface of the convex plate 142.

[0027] In this embodiment: the present invention can press and limit the rod wire by setting a positioning box 141, a convex plate 142 and a counterweight plate 143.

[0028] The implementation principle is as follows:

[0029] When using the device, if it is necessary to cut the bar wire to a fixed length, the operator places the bar wire at the bottom of the inner cavity of the concave plate 1, with one end of the bar wire tightly attached to the left side of the inner cavity of the concave plate 1. Then, the operator moves the slide plate 9, causing the slide plate 9 to drive the vertical plate 11 and the positioning box 141 to slide laterally on the outer surface of the slide rail 8. When the slide plate 9 moves the indicator arrow 17 to the specified cutting value of the scale 16, the cutting disc 13 moves to the specified cutting position of the bar wire. Then, the operator rotates the limiting bolts 10 on both sides in sequence, causing the limiting bolts 10 to rotate and move on the outer surface of the slide plate 9 and tightly attach to the connection of the slide rail 8, thereby limiting the connection between the slide plate 9 and the slide rail 8 and completing the fixed length of the cutting position of the cutting disc 13.

[0030] Next, the operator plugs in the rotary motor 12 and servo motor 4, and starts the external controller for the rotary motor 12 and servo motor 4. This causes the output of the rotary motor 12 to drive the cutting disc 13 to rotate. Simultaneously, the output of the servo motor 4 drives the drive gear 5 to rotate, which in turn drives the driven gear 3 to rotate. This causes the driven gear 3 to drive the rotating drum 2 to rotate and move along the threaded surface of the stud 6. This causes the stud 6 to move the lifting plate 7 downward, which in turn moves the positioning box 141 downward. This causes the positioning box 141 to move the convex plate 142, the counterweight plate 143, and the rubber pad downward. The device contacts the bar / wire material, which in turn supports it, thus achieving pressure and limiting of the bar / wire material. Simultaneously, the lifting plate 7 drives the vertical plate 11 to move downwards, causing the vertical plate 11 to drive the rotary motor 12 and the cutting disc 13 to move downwards and contact the bar / wire material. This allows the rotating cutting disc 13 to perform fixed-length cutting on the bar / wire material. This device is simple to operate and convenient for fixed-length cutting of bar / wire material, thus meeting customer needs. At the same time, it effectively avoids the loose connection between the existing baffle and connecting seat, which results in poor accuracy of baffle length cutting and affects the cutting precision of bar / wire material.
