In one or more embodiments of the present invention, the number of the guide wheels is four, and they are spaced and symmetrically disposed.

In one or more embodiments of the present invention, the anti-disengagement plate is symmetrically disposed below the supporting plate.

In one or more embodiments of the present invention, the clamping handle is provided with an anti-slip clamping block, and the anti-slip clamping block is detachably mounted.

In one or more embodiments of the present invention, the retractor member is hinged to the movable slider.

Compared with the prior art, the utility model the effect that exists is:

because the utility model adopts the above scheme, it has the advantages of stable operation, stable and reliable clamping, strong universality, durability, looseness prevention, separation prevention, etc.; therefore, it has excellent performance in technical, economical and practical aspects.

Drawings

Fig. 1 is a schematic perspective view of a drawing collet cart for a drawing machine according to an embodiment of the present invention.

Those skilled in the art can appreciate that the shapes, configurations and arrangements of the various elements shown in the drawings are not necessarily to scale, and that the dimensions of the various elements and components of the drawings may be exaggerated or minimized to more clearly illustrate the embodiments of the present invention described herein.

Detailed Description

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout.

The orientation shown in the drawings is not to be considered as limiting the scope of the invention, but merely as a reference to the preferred embodiments, changes in position or addition of numbers or structural simplifications may be made to the product parts shown in the drawings.

The relation of "connected" in the specification and "connected" between the components shown in the drawings may be understood as fixedly connected or detachably connected or integrally connected; the connecting elements can be directly connected or connected through an intermediate medium, and persons skilled in the art can understand the connecting relation according to specific conditions, and can use the connecting elements in a screwed connection or riveting connection or welding connection or clamping connection or embedding connection mode to replace different embodiments in a proper mode.

The terms of orientation such as up, down, left, right, top, bottom, and the like in the description and the orientation shown in the drawings, may be used for direct contact or contact with each other through another feature therebetween; above may be directly above and obliquely above, or it simply means above the other; other orientations may be understood by analogy.

The technical scheme and the beneficial effects of the invention are clearer and clearer by further describing the specific embodiment of the invention with the accompanying drawings of the specification; and are intended to be illustrative of the invention and not to be construed as limiting the invention.

While specific embodiments will be described below with reference to fig. 1, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for illustrative purposes only and should not be construed as limiting, the present invention preferably provides an embodiment of a drawing collet cart for a drawing machine comprising a support plate 1, a plurality of guide wheels 2 provided to said support plate 1, an anti-drop plate 3, and a clamping mechanism 4 provided to said support plate 1; the clamping mechanism 4 comprises a hook member 41, a movable sliding block 42 connected with the hook member 41, a scissor arm 43 connected with the movable sliding block 42 and a clamping hand 44; the movable sliding block 42 is hinged with the scissor arm 43, the movable sliding block 42 moves in cooperation with the guide limiting block 5, and the drag hook component 41 pulls the movable sliding block 42 to enable the scissor arm 43 to drive the clamping hands to clamp the workpiece for stretching.

The number of the guide rail wheels 2 is four, the guide rail wheels are arranged at intervals and symmetrically, and the clamping hands 44 are provided with anti-skidding clamping blocks 45. The clamping surface of the anti-skid clamping block 45 is provided with concave-convex grains, so that the anti-skid and anti-twist clamping is realized; the anti-slip clamp 45 may be made detachable, which facilitates replacement of the anti-slip clamp 45.

The hook members 41 are hinged to the movable slider 42, and when the movable slider is stretched, the hook members are hinged to increase the accommodating amount of the stretching angle, so that the movable slider 42 can move smoothly at the guide limiting block 5 more conveniently.

When the anti-drop hook device is used, the guide rail wheels 2 move on a main stroke guide rail of the stretcher, and the anti-drop hook plates 3 are symmetrically arranged below the support flat plate 1. The anti-drop hook plates 3 are clamped at two sides of the main stroke guide rail, so that the anti-drop hook plates are prevented from being separated, the safety is improved, and the clamping hands 44 are driven by the drag hook members 41 and the shear arms 4 to clamp and stretch the workpiece; therefore, the clamping device has the advantages of stable operation, stable and reliable clamping, strong universality, durability, looseness prevention, separation prevention and the like; therefore, it has excellent performance in technical, economical and practical aspects.

The foregoing description, for purposes of explanation, used specific nomenclature to provide a thorough understanding of the embodiments. However, it will be apparent to one skilled in the art that the specific details are not required in order to practice the embodiments. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and modifications and substitutions based on the known art are intended to fall within the scope of the present invention, which is defined by the claims.
