Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and more specifically, to a bolt processing cutting device. Background Technology

[0002] A bolt is a common mechanical fastener, typically consisting of a head and a shank (a cylinder with external threads). It works in conjunction with a nut to fasten multiple parts together. Its simple structure and reliable connection make it widely used in construction, automotive, machinery manufacturing, aerospace, and other fields. In the mass production of bolts, the cutting device is one of the key processing equipment. Its necessity is mainly reflected in the following aspects: the raw materials of bolts are usually metal bars (such as carbon steel, stainless steel, etc.), which are long and strip-shaped (such as bars with a diameter of several millimeters to tens of millimeters).

[0003] The primary function of the cutting device is to cut long bars into shorter blanks according to the required length for bolts. For example, to produce M10×30 bolts (with a shank length of 30mm), the bar needs to be cut into blanks of about 30mm in length for subsequent processing of the head and threads. However, currently, it is difficult to adjust the cutting according to the required length of the bar, resulting in uncontrollable cutting precision. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a bolt processing and cutting device, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a bolt processing and cutting device, including a base, on which a positioning and cutting component is provided; The positioning and cutting assembly includes two crossbars mounted on the base, and a lead screw is fixedly mounted on the outer side of each crossbar. A rubber pad is fixedly mounted on one end of each lead screw, and a threaded coil is threaded to the other end of each lead screw. Each of the two coils has a scale bar fixedly installed on the side away from the rubber pad, and each scale bar passes through the base and extends to one side of the base.

[0006] Optionally, in one possible implementation, the crossbar is inserted into the base and rotatably connected to the base, the scale rod is slidably connected to the base, a vertical plate is fixedly provided at one end of the base, a guide cylinder is provided at the top of the vertical plate, a hydraulic rod is provided at the top of the guide cylinder, a slide rod is provided at the output end of the hydraulic rod, the bottom end of the slide rod passes through the guide cylinder, the slide rod is slidably connected to the guide cylinder, a motor is provided on one side of the bottom of the slide rod, a cutting disc is provided at the output end of the motor, two lead screws are arranged side by side, an arc groove is opened on the base, and the arc groove is located between the two lead screws; The technical effects and advantages of this utility model are as follows: By setting two rotatable crossbars to drive the lead screw to rotate, and in conjunction with the threaded coil, the distance between the coil and the rubber pad can be adjusted. When the crossbars are rotated, the coil moves along the lead screw axis, thereby changing the distance between the two rubber pads. This distance directly corresponds to the cutting length of the bar stock, ensuring precise control of the cutting length. The scale rod passes through the base and is fixedly connected to the lead coil, providing linear guidance as the lead coil moves, preventing offset caused by lead screw rotation, and ensuring the stability of the positioning component during adjustment. Simultaneously, the exposed portion of the scale rod serves as a scale reference, allowing operators to visually confirm the adjustment stroke and further improve adjustment efficiency. The arc groove on the base, located between the two lead screws, precisely positions the axis of the bar stock, ensuring it remains horizontal during cutting and reducing cutting deviations caused by bar stock movement. The anti-slip textured surface of the rubber pad increases friction with the bar stock, preventing displacement during cutting and further improving cutting accuracy. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] As attached Figures 1-4 The bolt cutting device shown uses a positioning and cutting assembly on a base 1. Two rotatable crossbars 2 drive a lead screw 3 to rotate, which, in conjunction with a threaded coil 5, allows for adjustment of the distance between the coil 5 and the rubber pads 4. When the crossbars 2 rotate, the coil 5 moves axially along the lead screw 3, thereby changing the distance between the two rubber pads 4. This distance directly corresponds to the cutting length of the bar stock, ensuring precise control of the cutting length. The specific structural configuration of the assembly is as follows. The positioning and cutting assembly includes two crossbars 2 set on the base 1, and a lead screw 3 is fixedly set on the outer side of each crossbar 2. A rubber pad 4 is fixedly set on one end of each lead screw 3, and a threaded coil 5 is threadedly connected to the other end of each lead screw 3. Two wire loops 5 are fixedly provided with scale rods 6 on the side away from the rubber pad 4, and each scale rod 6 passes through the base 1 and extends to one side of the base 1.

[0015] Specifically, as shown in the attached document Figure 1 , 2 As shown in Figure 4, when cutting the bar stock, the bar stock is placed horizontally between the two lead screws 3 so that the end of the bar stock can abut against one side of the coil 5. The distance between the coil 5 and the rubber pad 4 is used to calibrate the cutting length of the bar stock to ensure the cutting accuracy of the bar stock. When adjusting, the horizontal bar 2 is rotated, which drives the lead screw 3 to rotate. The coil 5 is threadedly connected to the lead screw 3, which causes the coil 5 to move on the lead screw 3, thereby realizing the function of adjusting the position of the coil 5. At the same time, the scale rod 6 can guide and limit the movement of the coil 5 to ensure the stability of the adjustment. The adjustment stroke of the coil 5 can also be observed through the scale rod 6. A crossbar 2 is inserted into and rotatably connected to the base 1. A scale rod 6 is slidably connected to the base 1. A vertical plate 7 is fixedly installed at one end of the base 1. A guide cylinder 8 is installed at the top of the vertical plate 7. A hydraulic rod 9 is installed at the top of the guide cylinder 8. A slide rod 10 is installed at the output end of the hydraulic rod 9. The bottom end of the slide rod 10 passes through the guide cylinder 8 and is slidably connected to the guide cylinder 8. A motor 11 is installed on one side of the bottom of the slide rod 10. A cutting disc 12 is installed at the output end of the motor 11. Two lead screws 3 are arranged side by side. An arc groove is opened on the base 1, and the arc groove is located between the two lead screws 3. Specifically, as shown in the attached document Figure 1 , 2As shown in Figure 3, the hydraulic rod 9 drives the slide rod 10 to move the motor 11 and the cutting disc 12, so that the cutting disc 12 can contact the bar stock. The motor 11 drives the cutting disc 12 to rotate, so that the cutting disc 12 can cut the bar stock. The arc groove is designed to facilitate the positioning of the bar stock when it is placed horizontally between the two lead screws 3, ensuring the cutting stability. The specific working principle is as follows: The operator rotates the horizontal bar 2. Since the horizontal bar 2 is rotatably connected to the base 1, it drives the outer lead screw 3 to rotate synchronously. The lead screw 3 and the coil 5 are connected by threads. When the lead screw 3 rotates, the coil 5 moves along the axial direction of the lead screw 3. At this time, the scale rod 6 fixed on one side of the coil 5 slides synchronously in the guide hole of the base 1 to ensure the straightness of the movement trajectory of the coil 5. If the horizontal bar 2 is rotated clockwise, the coil 5 moves closer to the rubber pad 4, reducing the distance between the two rubber pads 4; if rotated counterclockwise, the distance increases. The size of the distance can be read visually through the exposed scale of the scale rod 6.

[0016] According to the target cutting length, such as 30mm, place one end of the bar against one side of the wire coil 5, and adjust the position of the wire coil 5 by rotating the crossbar 2 so that the distance between the wire coil 5 and the rubber pad 4 is equal to the target length, thus completing the calibration of the cutting length.

[0017] The bar is placed horizontally within the arc groove of the base 1, with the curved surface of the groove fitting against the outer circumference of the bar to achieve axial positioning. Both ends of the bar rest against two rubber pads 4, the elastic material of which provides friction to prevent slippage. The hydraulic rod 9 is activated, and its output end pushes the slide rod 10 to slide downward along the guide cylinder 8. The slide rod 10 drives the motor 11 at the bottom to move downward synchronously with the cutting disc 12. When the cutting disc 12 contacts the surface of the bar stock, the motor 11 starts, driving the cutting disc 12 to rotate at high speed. The hydraulic rod 9 continues to press down, causing the cutting disc 12 to cut into the bar stock until the cut is completed.

[0018] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
