Description

Technical Field

[0001] This utility model relates to the field of metal material processing equipment technology, and in particular to a pot-shaped clamping wheel tube straightening mechanism for a metal material rotary stretching equipment. Background Technology

[0002] Rotary stretching of metal materials is a highly efficient and precise plastic forming process. It applies continuous localized loads to a metal material rotating synchronously with the tooling via a forming wheel, causing the metal to deform point-by-point into cylindrical, conical, or other rotating components. It is particularly widely used in the manufacturing of cookware, pressure vessels, and other hardware products, as well as high-end equipment. The coaxiality and rotational stability of the metal material are the core factors determining the accuracy, wall thickness uniformity, and product yield of rotary stretching. Therefore, rotary stretching equipment typically requires a metal material guiding mechanism to ensure that the metal material coincides with the axis of the rotating support before being pressed by the pressure plate. Currently, the metal material guiding method in rotary stretching equipment before unloading largely relies on manual visual alignment, resulting in low positioning accuracy and poor processing efficiency. Utility Model Content

[0003] The problem to be solved by this utility model is to provide a pot-shaped clamping wheel tube straightening mechanism for a metal material rotary stretching device. This pot-shaped clamping wheel tube straightening mechanism for a metal material rotary stretching device can automatically center and feed materials, thereby improving positioning accuracy and processing efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A metal material rotary stretching device with a pot-shaped clamping wheel tube straightening mechanism includes a frame, a rotary support, and a rotary drive mechanism capable of driving the rotary support to rotate. The rotary drive mechanism is mounted on the frame. The device is characterized by further including a slide rail, a slider, a translation seat, a translation cylinder, two clamping arms, and two clamping wheels. The slide rail is horizontally mounted on the frame. The slider is located on the slide rail and can move along it. The translation seat is mounted on the slider. The translation cylinder is mounted on the frame, with the piston rod of the translation cylinder extending towards the rotary support. The translation seat is connected to the end of the piston rod of the translation cylinder. The fixed ends of the two clamping arms are hinged to the translation seat. The two clamping wheels are rotatably mounted on the movable ends of the corresponding clamping arms. A tube straightening angle is formed between the two clamping arms, enabling tube straightening of the metal material. The opening of the tube straightening angle is located on one side of the rotary support and faces the rotary support. An angle locking structure is provided between the movable ends of the clamping arms and the translation seat.

[0005] Before use, pre-adjust the tube-positive angle between the two clamping arms. Since there is an angle locking structure between the movable end of the clamping arm and the translation seat, after adjusting the opening of the tube-positive angle, the clamping arm and the translation seat are fixed relative to each other by the angle locking structure to ensure the stability of the angle.

[0006] In use, the translation cylinder is activated, and the piston rod of the translation cylinder extends toward the rotating support, driving the translation seat, two clamping arms, and clamping wheels to move forward along the slide rail until the preset working position is reached and then stopped. Then, the metal material is placed on the rotating support, so that the edge of the metal material contacts and engages with the two clamping wheels, and the outer periphery of the metal material contacts the two clamping wheels simultaneously. Relying on the centering characteristics of the tube's positive angle, the center of the metal material automatically coincides with the axis of the rotating support, completing the pre-positioning of the material, which facilitates the subsequent descent of the pressing plate of the pressing mechanism to accurately press it into the center position of the metal material.

[0007] When the rotary drive mechanism is activated, the piston rod of the translation cylinder retracts, causing the translation seat, clamping arm, and clamping wheel to move backward along the slide rail, so that the clamping wheel completely disengages from the edge of the metal material, thus clearing the space for the metal material to be rotated and formed.

[0008] In a preferred embodiment, the included angle locking structure includes a first locking bolt, a first screw hole on the translation seat, and an arc-shaped adjustment hole on the fixed end of the clamping arm. The arc-shaped adjustment hole is centered on the hinge position of the fixed end of the clamping arm. The first screw hole corresponds to the arc-shaped adjustment hole. The shank of the first locking bolt passes through the arc-shaped adjustment hole and is screwed into the first screw hole. The head of the first locking bolt and the translation seat together clamp the fixed end of the clamping arm. The diameters of the metal products subjected to the above-mentioned rotational stretching of metal materials are different. Loosen the first locking bolt to release the clamping constraint on the clamping arm. At this time, the clamping arm can rotate around the hinge axis at its fixed end, and the shank of the first locking bolt slides relative to each other along the arc-shaped adjustment hole. Adjust the opening angle of the two clamping arms according to the diameter of the target metal material so that the tube's positive angle matches the specifications of the metal material, ensuring that the metal material is placed in and makes contact with and aligns with the clamping wheels on both sides. After adjustment, retighten the first locking bolt. The clamping force between the head of the first locking bolt and the translation seat will fix the clamping arm on the translation seat, thus completing the locking of the tube's positive angle.

[0009] In a further preferred embodiment, the translation base is provided with multiple second screw holes, one of which houses a second locking bolt. The fixed end of the clamping arm has a mounting through hole, through which the shank of the second locking bolt passes. The head of the second locking bolt, together with the translation base, clamps the fixed end of the clamping arm. Through the cooperation of the second locking bolt, the mounting through hole, and the second screw hole, the fixed end of the clamping arm is hingedly mounted on the translation base. The multiple second screw holes on the translation base enable adjustable positions for the clamping arm.

[0010] In a preferred embodiment, the included angle of the tube is in the range of 60°-150°. The opening size of the included angle is moderate, allowing the metal material to be quickly pre-positioned for loading with the assistance of the included angle.

[0011] In a preferred embodiment, the clamping wheel includes a limiting post and a rubber sleeve. The limiting post is rotatably mounted on the movable end of the corresponding clamping arm, and the rubber sleeve is fitted onto the limiting post. The rubber sleeve is made of a flexible material, so that the metal material will not cause scratches or other appearance defects when it comes into contact with the clamping wheel during loading and unloading. Moreover, the friction coefficient between rubber and metal materials is higher, resulting in better anti-slip and positioning effects.

[0012] In a further preferred embodiment, the limiting post is rotatably mounted on the upper surface of the movable end of the corresponding clamping arm.

[0013] In another further preferred embodiment, the limiting post is rotatably mounted on the lower surface of the movable end of the corresponding clamping arm.

[0014] The aforementioned rotary drive mechanism is existing technology and will not be described in detail here.

[0015] Compared with the prior art, this utility model has the following advantages: This invention can automatically center and feed materials, automatically correct the eccentricity of metal materials, and make the axis of the metal material coincide with the axis of the rotating support to ensure coaxiality. At the same time, by adjusting the opening size of the included angle, it can be adapted to metal materials of different diameters, thereby improving the processing adaptability range of the equipment.

Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1-4As shown, the metal material rotary stretching equipment in this embodiment includes a frame 1, a rotating support 2, a slide rail 3, a slider 4, a translation seat 5, a translation cylinder 6, two clamping arms 7, two clamping wheels 8, and a rotation drive mechanism capable of driving the rotating support 2 to rotate. The rotation drive mechanism is mounted on the frame 1. The slide rail 3 is horizontally mounted on the frame 1, the slider 4 is located on the slide rail 3 and can move along the slide rail 3, the translation seat 5 is mounted on the slider 4, and the translation cylinder 6 is mounted on the frame 1. The piston rod of cylinder 6 extends towards the rotating support 2. The translation seat 5 is connected to the end of the piston rod of the translation cylinder 6. The fixed ends of the two clamping arms 7 are hinged to the translation seat 5. The two clamping wheels 8 are rotatably mounted on the movable ends of the corresponding clamping arms 7. The two clamping arms 7 form a tube-aligning angle 71 that can straighten the metal material 9. The opening of the tube-aligning angle 71 is on one side of the rotating support 2 and faces the rotating support 2. An angle locking structure 10 is provided between the movable end of the clamping arm 7 and the translation seat 5.

[0019] Before use, pre-adjust the tube positive angle 71 between the two clamping arms 7. Since there is an angle locking structure 10 between the movable end of the clamping arm 7 and the translation seat 5, after adjusting the opening of the tube positive angle 71, the clamping arm 7 and the translation seat 5 are fixed relative to each other by the angle locking structure 10 to ensure that the size of the angle is stable.

[0020] In use, the translation cylinder 6 is activated, and the piston rod of the translation cylinder 6 extends toward the rotating support 2, driving the translation seat 5, the two clamping arms 7 and the clamping wheels 8 to move forward along the slide rail 3 until the preset working position is reached and then stopped. Then, the metal material 9 is placed on the rotating support 2, so that the edge of the metal material 9 contacts and engages with the two clamping wheels 8, and the outer periphery of the metal material 9 contacts the two clamping wheels 8 at the same time. Relying on the centering characteristics of the tube positive included angle 71, the center of the metal material 9 automatically coincides with the axis of the rotating support 2, completing the pre-positioning of the material, which facilitates the subsequent descent of the pressure plate of the pressing mechanism and precise pressing into the center position of the metal material 9.

[0021] When the rotation drive mechanism is activated, the piston rod of the translation cylinder 6 retracts, causing the translation seat 5, clamping arm 7 and clamping wheel 8 to move backward along the slide rail 3 as a whole, so that the clamping wheel 8 completely disengages from the edge of the metal material 9, thus avoiding the rotational forming space of the metal material 9.

[0022] The angle locking structure 10 includes a first locking bolt 101, a first screw hole 102 on the translation seat 5, and an arc-shaped adjustment hole 103 on the fixed end of the clamping arm 7. The arc-shaped adjustment hole 103 is centered on the hinge position of the fixed end of the clamping arm 7. The first screw hole 102 corresponds to the arc-shaped adjustment hole 103. The shank of the first locking bolt 101 passes through the arc-shaped adjustment hole 103, and the shank of the first locking bolt 101 is screwed into the first screw hole 102. The head of the first locking bolt 101 and the translation seat 5 together clamp the fixed end of the clamping arm 7. The diameters of the metal products rotated and stretched from the aforementioned metal material 9 are different. Loosen the first locking bolt 101 to release the clamping constraint on the clamping arm 7. At this time, the clamping arm 7 can rotate around the hinge axis at its fixed end, and the rod of the first locking bolt 101 slides relative to each other along the arc-shaped adjustment hole 103. Adjust the opening angle of the two clamping arms 7 according to the diameter of the target metal material 9 so that the tube positive angle 71 matches the specifications of the metal material 9, ensuring that the metal material 9 is just in contact and aligned with the clamping wheels 8 on both sides after being placed in place. After the adjustment is in place, tighten the first locking bolt 101 again. The clamping force between the head of the first locking bolt 101 and the translation seat 5 fixes the clamping arm 7 on the translation seat 5, thus completing the locking of the tube positive angle 71.

[0023] The translation base 5 has multiple second screw holes 51, one of which houses a second locking bolt 52. The fixed end of the clamping arm 7 has a mounting through hole 72. The shank of the second locking bolt 52 passes through the mounting through hole 72, and the head of the second locking bolt 52, together with the translation base 5, clamps the fixed end of the clamping arm 7. Through the cooperation of the second locking bolt 52, the mounting through hole 72, and the second screw holes 51, the fixed end of the clamping arm 7 is hingedly mounted on the translation base 5. The multiple second screw holes 51 on the translation base 5 allow for adjustable positions of the clamping arm 7.

[0024] The included angle 71 of the tube has an angle range of 80°. The opening size of the included angle 71 of the tube is moderate, and the metal material 9 can be quickly pre-positioned for loading with the assistance of the included angle 71 of the tube.

[0025] The clamping wheel 8 includes a limiting post 81 and a rubber sleeve 82. The limiting post 81 is rotatably mounted on the movable end of the corresponding clamping arm 7, and the rubber sleeve 82 is fitted onto the limiting post 81. The rubber sleeve 82 is made of flexible material, so that the metal material 9 will not cause scratches or other appearance defects when it comes into contact with the clamping wheel 8 during loading and unloading. Moreover, the friction coefficient between the rubber and the metal material 9 is higher, resulting in better anti-slip and stable positioning.

[0026] The limiting post 81 is rotatably mounted on the upper surface of the movable end of the corresponding clamping arm 7.
