The advantages are that: firstly, the motion resistance of the eccentric driving tube is reduced, the manual cutting resistance is small, and the hand feeling is easy; secondly, the cutting of the blade and the pressing of the highest bulge of the eccentric driving tube on the same vertical line are realized, and the defects in the prior art are overcome. However, the eccentric driving pipe of the utility model has the advantages that the size of the eccentric driving pipe can not cut composite boards with different thicknesses, and a composite board cutting machine matched with the eccentric driving pipe is required to be selected according to the thickness of the composite board.
Disclosure of Invention
The design purpose is as follows: the defects in the background technology are avoided, and the eccentric driving tube for the composite board cutting machine, which can be suitable for cutting composite boards with different thicknesses, is designed.
The design scheme is as follows: in order to achieve the above design objective. The utility model is structurally designed:
1. the design that the eccentric driving tube in the composite board cutting machine is replaced by a plurality of swinging blocks is one of the technical characteristics of the utility model. The purpose of this design is: according to the utility model, an arc structure generating downward pressure in the prior art is designed into a pendulum block involute structure, and the downward moving distance of the pendulum block downward pressing cutter fixing frame depends on the involute stroke, so that the length of the involute before and after the generation line is straightened is unchanged, namely the length of the generation line rolling along a base circle is equal to the length of the arc rolled along the base circle, and the normal line of any point on the involute is tangential to the base circle, so that the generated resistance is relatively small compared with a cam. The swing blocks designed by the utility model have three different strokes respectively, and the swing blocks with different strokes can be replaced according to the thickness requirement of the cut composite board in the use process so as to meet the cutting requirement: the swinging block rotates for 90 degrees under the action of the compression bar and contacts with the cutter fixing frame at the same time, so that the cutter fixing frame and the cutter are forced to move downwards by the same distance.
For example: in contrast to the products of the prior art: the power arm length of the product in the prior art is unchanged, and under the condition that the power arm length of other products is 56mm, when the lower pressure is unchanged (30 x 800)/56= 528.5KG;
summarizing the test verification: the cutting force of the vertical downward pressing in the prior art on the composite board needs 800KG to achieve the cutting effect; the cutting resistance of the blunt knife used in the utility model can reach 1600KG, namely:
cut-off composite board with stroke of 22mm swing block corresponding to 1600x 22/800=44 KG
Cut-away composite board with stroke of 17mm swing block corresponding to 1600x 17/800=34 KG
Cut-off composite board with stroke of 13mm swing block corresponding to 1600x 13/800=26 KG
In contrast to the products of the prior art: the power arm length of the product in the prior art is unchanged, under the condition that the resistance arm length of other products is 56mm, 800x 56/800=56 KG can cut the composite board, and the utility model uses the swinging block structure only to 44KG at maximum, so that the composite board can be cut, and compared with the product in the prior art, the utility model can save labor:
the stroke 22mm pendulum corresponds to 56-44=12kg
The stroke 17mm pendulum corresponds to 56-34=22 KG
The travel 13mm pendulum corresponds to 56-26=30kg
The calculation shows that the same cutting of the composite board is performed, and the same effect of the product can be achieved by using a force which is more than 12 KG-30 KG when the product is used for cutting the same sheet material.
2. The design of the insertion fit between the swinging block 15 and the movable cross bar 16 is the second technical feature of the utility model. The purpose of this design is: because the swing block is provided with the convex T-shaped protruding head on the structural design and the connection surface of the movable cross rod and the swing block, the connection surface of the movable cross rod and the swing block is provided with the T-shaped groove slide way with the cross section, the T-shaped protruding head on the T-shaped groove slide way and the swing block are in inserted connection and matched with each other to be positioned by screws, and the swing block can move in the T-shaped groove slide way before being positioned, the purpose can conveniently adjust the swing position, and the swing blocks with different strokes can be replaced according to the cut composite board slabs, so that the three composite boards with different thicknesses can be cut by one machine, and three different machine types in the prior art are replaced.
The technical scheme is as follows: the eccentric driving pipe for the composite board cutting machine is replaced by a plurality of swinging blocks and movable cross bars, and the swinging blocks are in splicing fit with the movable cross bars.
Compared with the background technology, the utility model firstly replaces the whole convex roller section bar in the prior art with three swinging blocks, and the three swinging blocks are arranged on the conventional standard component section bar, thereby being convenient for long-time use in later period and convenient for maintenance and quick replacement after abrasion; secondly, realize a tractor serves several purposes, because the pendulum mass sets up three strokes and is 13mm, 17mm, 22mm respectively, can consider which stroke is fairly suitable or change the pendulum mass of which stroke into in the time of purchasing and using, need not purchase three different models.
