Description

Technical Field

[0001] This utility model relates to the field of scissor clip technology, and particularly to a scissor clip for aluminum alloy bars in a hot state. Background Technology

[0002] With the stable, continuous and rapid development of my country's national economy and high technology, my country's aluminum smelting and aluminum profile processing industries have developed very rapidly. In the 21st century, China's aluminum processing industry has closely combined with the needs of market and scientific development, and has gradually completed the transformation of traditional aluminum processed materials into modern aluminum processed materials. As a result, the varieties of aluminum processed profiles in China have undergone tremendous changes, among which aluminum rods are widely used as a raw material for aluminum profile processing.

[0003] During the processing of aluminum rods, short-distance transfer of the aluminum rods is required. Generally, iron clamps are used to hold the aluminum rods for transfer. However, since the surface hardness of the aluminum rod decreases after heating, and the iron clamps only have one clamping point, they can only clamp the center part of the aluminum rod for stability, or two people can clamp both ends of the aluminum rod at the same time to maintain stability. When one person clamps, it is easy to damage the center area and processing area of ​​the aluminum rod. Clamping by two people is also more labor-intensive. In view of this, we have proposed a scissor clamp for aluminum alloy rods in the hot state. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a scissor clamp for aluminum alloy bars in a hot state, comprising a clamp consisting of two arc-shaped clamping parts and two control handles.

The upper and lower ends of the limiting rods extend beyond the limiting sleeves. A first connecting plate is fixedly connected to the lower ends of the front and rear limiting rods, and a second connecting plate is fixedly connected to the upper ends of the middle two limiting rods.

The lower clamp and the upper clamp are also arc-shaped, and the curvature of the lower clamp and the upper clamp is greater than that of the arc-shaped clamping parts. An adjustment component is provided on the arc-shaped clamping parts.

[0006] Preferably, the adjustment assembly includes two adjustment blocks, which are respectively fixedly connected to the opposite side surface of the arc-shaped clamping part, and the upper ends of the front and rear limiting rods are fixedly connected to a first displacement plate.

[0007] Preferably, the lower ends of the two middle limiting rods are fixedly connected to a second displacement plate, and the upper surface of the first displacement plate is provided with a clearance hole extending out of its lower surface.

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a scissor clamp for aluminum alloy bars in a hot state, including a clamp 1. The clamp 1 consists of two arc-shaped clamping parts 2 and two operating handles 3. Four limiting sleeves 4 are fixedly connected to opposite sides of the two arc-shaped clamping parts 2. Limiting rods 5 are slidably fitted inside each of the four limiting sleeves 4. The upper and lower ends of the limiting rods 5 extend out of the limiting sleeves 4. The lower ends of the front and rear limiting rods 5 are fixedly connected to a first connecting plate 6, and the upper ends of the middle two limiting rods 5 are fixed... A second connecting plate 7 is connected, and a lower clamp 8 and an upper clamp 9 are fixedly connected to the first connecting plate 6 and the second connecting plate 7, respectively. The lower clamp 8 and the upper clamp 9 are also set in an arc shape, and the curvature of the lower clamp 8 and the upper clamp 9 is greater than that of the arc-shaped clamping part 2. An adjustment component is provided on the arc-shaped clamping part 2. With the addition of the upper clamp 9 and the lower clamp 8, a single person can conveniently clamp both ends of the hot aluminum rod at the same time, avoid damage to the central processing area of ​​the hot aluminum rod, and effectively improve the stability of the hot aluminum rod during the clamping process.

[0019] Furthermore, the adjustment assembly includes two adjustment blocks 10, which are respectively fixedly connected to opposite sides of the arc-shaped clamping part 2. The upper ends of the front and rear limit rods 5 are fixedly connected to a first displacement plate 11, and the lower ends of the middle two limit rods 5 are fixedly connected to a second displacement plate 12. The upper surface of the first displacement plate 11 has a clearance hole 13 extending from its lower surface, the diameter of which is larger than that of the limit rod 5. Connecting ears 14 are fixedly connected to the surfaces of the first displacement plate 11 and the second displacement plate 12 away from the axis of the arc-shaped clamping part 2. A bidirectional threaded rod 15 is rotatably fitted inside the adjustment block 10, with both its upper and lower ends rotatably extending outwards from the adjustment block 10. The two connecting ears 14 are respectively threaded onto the two opposite threads of the bidirectional threaded rod 15. The section 10 has a cavity 16 inside. A first bevel gear 17 is sleeved on the outer surface of the bidirectional threaded rod 15 inside the cavity 16. A second bevel gear 18 is meshed with the outer surface of the first bevel gear 17. A drive shaft 19 is fixedly connected to the side of the second bevel gear 18 away from the arc-shaped clamping part 2. The end of the drive shaft 19 away from the second bevel gear 18 rotates through the outside of the adjusting block 10. A knob 20 is fixedly connected to the end of the drive shaft 19 outside the adjusting block 10. By using the bidirectional threaded rod 15 in conjunction with the first displacement plate 11 and the second displacement plate 12, the gap between the upper clamp 9 and the lower clamp 8 can be adjusted relatively easily, thereby avoiding the problem of not being able to clamp when the aluminum rod is short or not being able to clamp both ends when the aluminum rod is long, thus improving the applicability of the scissor clamp.

[0020] Working principle: When clamping and transferring a hot aluminum rod, the two arc-shaped clamping parts 2 can be unfolded by controlling the handle 3. As the arc-shaped clamping parts 2 unfold, the limiting sleeve 4 simultaneously drives the limiting rod 5 to move. After the limiting rod 5 moves, it cooperates with the first connecting plate 6 and the second connecting plate 7 to drive the upper clamp 9 and the lower clamp 8 to move. Then, the two arc-shaped clamping parts 2 are brought closer together by the handle 3, thereby bringing the two lower clamps 8 and the upper clamp 9 closer together. The two sets of lower clamps 8 and upper clamps 9 are used to clamp both ends of the hot aluminum rod. If the length of the hot aluminum rod is too long or too short than the gap between the upper clamp 9 and the lower clamp 8, then... By rotating the knob 20, the knob 20 will synchronously drive the drive shaft 19 to rotate. When the drive shaft 19 rotates, it will synchronously drive the second bevel gear 18 to rotate. After the second bevel gear 18 rotates, it will cooperate with the first bevel gear 17 to drive the bidirectional threaded rod 15 to rotate. Since the movement trajectory of the first displacement plate 11 and the second displacement plate 12 is restricted by the limiting rod 5 and the limiting sleeve 4, and the movement trajectory of the connecting ear 14 is restricted by the first displacement plate 11 and the second displacement plate 12, when the bidirectional threaded rod 15 rotates, it will synchronously drive the first displacement plate 11 and the second displacement plate 12 to move in opposite directions, thereby controlling the gap between the upper clamp 9 and the lower clamp 8.

[0021] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
