Description

Technical Field

[0001] The utility model relates to the technical field of mechanical industry, in particular to a double-station continuous straightening machine. Background Art

[0002] With the development of the times, medical titanium alloys, as metal materials for medical implants, are ideal materials for manufacturing artificial joints, titanium bone pins, ultrasonic scalpels, Kirschner wires and other medical devices. Due to the advantages of titanium alloys such as high strength, corrosion resistance, and biocompatibility, titanium alloys have been widely used in aerospace, medical and other fields. Since the subsequent medical device processing has high requirements for wire straightness, the straightening process becomes a very important part of the finishing process in the production of titanium alloy wires, which has a great influence on the final performance and surface state of the material.

[0003] In general production, two-roller straightening and multi-roller straightening are mainly used for the processing of bars above 7.0. Sinusoidal straightening is widely used for rods, wires and tubes with simple cross-sections. Traditional sine straightening has a great destructive effect on the yield properties of the wire due to the rotational extrusion of the wire, which greatly reduces the yield strength of the material. When small-sized titanium alloy rods and wires need to be straightened, the sine straightening method is continued to be used, which leads to an increase in the destructive effect on the yield properties of the rods and wires, and the yield strength of the rods and wires is greatly reduced. The straightening process is more cumbersome than that of large-sized rods and wires, which increases the difficulty of the work. Utility Model Content

It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0022] See also Figures 1-2 In the embodiment of the utility model, a double-station continuous straightening machine includes a base 1, a four-roller transmission guide wheel 2, a box-type electric heating furnace 5, a straightening crawler transmission device 7, and a control system.

[0023] The details are as follows, including:

[0024] See also Figure 1 , Figure 2 , a base 1, a four-roller transmission guide wheel 2, a box-type electric heating furnace 5, and a straightening crawler transmission device 7 are sequentially arranged along the conveying direction of the material, and the four-roller transmission guide wheel 2, the box-type electric heating furnace 5, and the straightening crawler transmission device 7 are installed on the base 1;

[0025] It also includes a control system, which is installed on the base 1. The control system communicates with the four-roller drive guide wheel 2 and the straightening crawler drive device 7. When the material is transported to the straightening crawler drive device 7, the control system controls the four-roller drive guide wheel 2 and the straightening crawler drive device 7 to clamp the material, and controls the speed difference between the conveying speed of the four-roller drive guide wheel 2 and the straightening crawler drive device 7.

[0026] In detail, in order to solve the problem of continuous straightening of small-sized titanium alloy rods and wires, the double-station continuous straightening machine described in the utility model is adopted. When in use, when two materials are conveyed to the straightening crawler transmission device 7, the two materials have passed through the box-type electric heating furnace 5 for heating. The control system controls the four-roller transmission guide wheel 2 and the straightening crawler transmission device 7 to clamp the two materials, and drives the four-roller transmission guide wheel 2 and the straightening crawler transmission device 7 to convey the two materials respectively. The conveying speed difference between the four-roller transmission guide wheel 2 and the straightening crawler transmission device 7 is controlled to form a pulling force on the two materials along the axial direction, thereby realizing the straightening of the two materials and ensuring the yield performance and yield strength of small-sized materials during the straightening process. Among them, by changing the transmission speed of the straightening crawler transmission device 7, the straightening of materials with different hardnesses can be achieved.

[0027] Of course, the control system includes a control cabinet arranged on the base 1, and the control cabinet includes a tensioning button 8 of the straightening track transmission device and a tensioning button of the four-roller transmission guide wheel 2, and can respectively control the transmission speed of the four-roller transmission guide wheel 2 and the straightening track transmission device 7, and change the transmission size of the straightening track transmission device 7 to adjust the tension during material correction.

[0028] The four-roller transmission guide wheel 4 includes four rollers, the two rollers located at the bottom are rotatably installed on the base 1 and are connected to the rotation counter 3 installed on the base 1, and the two rollers located at the top are movably installed on the base 1 and can slide relative to the base 1.

[0029] The box-type electric heating furnace 5 is symmetrically provided with conduits 6 , and the base 1 is mounted with a box-type electric heating furnace temperature control panel 4 for controlling the box-type electric heating furnace 5 .

[0030] The straightening crawler track transmission device 7 includes four groups of crawler track transmission parts, two of which are rotatably installed on the base 1, and the other two groups of crawler track transmission parts are movably installed on the base 1 and can slide relative to the base 1.

[0031] An automatic cutting device 9 is installed on the base 1, and the automatic cutting device 9 is arranged at the output end of the straightening crawler transmission device 7 along the conveying direction of the material. It should be noted that the automatic cutting device 9 includes an upper knife seat, a lower knife seat, a cylinder, a hydraulic station and other parts, and uses the force generated by liquid pressure to complete the material cutting work.

[0032] The base 1 is fixedly connected with a loading platform 12 , which is arranged parallel to and flush with the base 1 , and a plurality of transmission guide wheels 11 are rotatably mounted on the loading platform 12 .

[0033] A plurality of shifting rods 10 are mounted on the loading platform 12 , and the shifting rods 10 are arranged in the gap between two adjacent transmission guide wheels 11 .

[0034] A sensor 13 is fixedly mounted on the loading platform 12 . The sensor 13 establishes communication with the shifting rod 10 . The sensor 13 is located at the end of the conveying direction of the conveying guide wheel 11 .

[0035] In general, when in use, first start the power switch, turn on the equipment, pass two materials through the middle of the four-roller transmission guide wheel 2, and pass through the rotation counter 3. The data displayed on the rotation counter 3 can record the length of the straightened material. At this time, the two materials enter the conduit 6 at the end of the box-type electric heating furnace 5. The materials are heated in the conduit 6, which can not only improve the plasticity of the materials, but also facilitate the relaxation of the compressive stress of the concave part. After the materials pass through the box-type electric heating furnace 5, they continue to move forward for a distance until the length is greater than the shortest clamping length, and the four-roller transmission guide wheel 2 is clamped. At this time, the materials have reached the straightening crawler transmission device 7, wherein 4 sets of crawlers are formed on the straightening crawler transmission device 7, and the two materials are respectively sent into the upper and lower crawlers. In the slot of the belt, the straightening crawler transmission device tensioning button 8 is pressed through the control system, the upper and lower crawlers are closed, the material is clamped in the crawler, and the transmission speed of the four-roller transmission guide wheel 2 and the straightening crawler transmission device 7 is set through the electric control cabinet. The straightening crawler transmission device 7 is driven by the frequency conversion motor to start running, so that a pulling force is formed on the two materials along the axial direction, so that the shapes of the two materials are smoothly straightened. When the automatic cutting device 9 receives the fixed-length cutting instruction, the scissors bite the two materials and start cutting. The cut wire is transmitted forward through the transmission guide wheel 11. When it reaches the position of the sensor 3, the sensor 13 sends a signal to the lever 10, and the lever 10 starts to work and dials the material onto the loading platform 12 to realize the automatic cutting of the straightened material.
