The utility model is realized in the following way: a traction clamping mechanism for a composite pultruded profile, comprising:
an upper fixing plate;
the lower fixing plate is arranged right below the upper fixing plate;
the upper clamping block is arranged at the bottom end of the upper fixing plate, and the bottom end is provided with at least one first imitation groove matched with the shape of the workpiece;
the lower clamping block is arranged at the top end of the lower fixing plate and is opposite to the upper clamping block, and at least one second imitation groove matched with the shape of the workpiece is arranged at the top end of the lower clamping block;
the upper clamping blocks and the lower clamping blocks are PU polyurethane blocks.
The utility model has the advantages that:
at least one first imitation groove matched with the shape of the workpiece is formed in the bottom end of the upper clamping block, at least one second imitation groove matched with the shape of the workpiece is formed in the top end of the lower clamping block, and the contact area with the workpiece can be effectively increased through the first imitation groove and the second imitation groove; and go up grip block and lower grip block and be PU polyurethane piece, have excellent wearability (durable), mechanical strength is high, toughness is good (flexible contact, the work piece can not the centre gripping crack), coefficient of friction is high (difficult skidding), advantage such as material workable, final very big reduction composite pultrusion's manufacturing cost, very big improvement yields.
Drawings
The utility model will be further described with reference to examples of embodiments with reference to the accompanying drawings.
Fig. 1 is a cross-sectional view of a traction gripping mechanism for a composite pultruded profile of the present utility model.
Fig. 2 is a cross-sectional view of a conventional clamping block.
Marking:
100-a traction clamping mechanism for a composite pultruded profile, wherein the traction clamping mechanism comprises a 1-upper fixing plate, a 2-lower fixing plate, a 3-upper clamping block, a 4-lower clamping block, a 5-workpiece, a 31-first profiling groove, a 41-second profiling groove and a 200-traditional clamping block.
Description of the embodiments
The embodiment of the utility model solves the technical problems that the clamping block for clamping the workpiece is a rigid clamping block in the prior art, the manufacturing cost is high, the section is simple, the clamping block is not matched with the profile, the clamping block is easy to slip and deform during traction, and the yield is affected by the fact that the clamping block is used for the traction of the composite pultrusion profile, so that the production cost of the composite pultrusion profile is greatly reduced, and the yield is greatly improved.
The technical scheme in the embodiment of the utility model aims to solve the problems, and the overall thought is as follows: the profiling grooves 31/41 matched with the workpiece 5 in shape are formed in the upper clamping block 3 and the lower clamping block 4 to increase the contact area, and the upper clamping block 3 and the lower clamping block 4 are PU polyurethane blocks, so that the novel steel plate composite pultrusion type plastic has the advantages of being excellent in wear resistance, high in mechanical strength, good in toughness, high in friction coefficient, easy to machine in material and the like, the production cost of composite pultrusion is reduced, and the yield is improved.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
Referring to fig. 1-2, a preferred embodiment of a traction and clamping mechanism 100 for composite pultrusions according to the present utility model includes:
