Background
Sawing machines can be divided into two categories, horizontal and vertical, and generally, the vertical sawing machine refers to a circular saw machine, namely a sawing machine using an alloy saw blade. Circular sawing machines have been widely used for sawing logs and boards in the processes of longitudinal cutting, transverse cutting, edge cutting, grooving and the like. In the sawing process, the saw blade rotates at a high speed, a saw seam with a certain length is generated on a cut workpiece, and the cut workpiece is clamped and deformed towards the saw seam due to tension, so that the saw blade is clamped, the cutting surface of the workpiece is uneven, the saw blade is abraded and even damaged, the service life of the saw blade is shortened, and the sawing difficulty is increased. The conventional solution is to add a lifting anti-pinch structure above or below the workpiece, so that the whole structure is complicated and occupies large space. Because the saw blade and the pressing device are arranged above the workpiece on the vertical circular sawing machine, and the supporting table is arranged below the workpiece, proper installation conditions are not provided, the structure change is troublesome, and the cost is high.
SUMMERY OF THE UTILITY MODEL
In view of the problem that exists among the prior art, the utility model provides a compact structure's vertical circular sawing machine saw bit anti-pinch device, the technical scheme of adoption is, including the movable clamp that is located the work piece both sides to the direction of feed of saw bit is preceding, and movable clamp includes preceding tight piece of clamp and the tight piece of back clamp, is equipped with on the tight piece of back clamp and moves back the tool gap, moves back the tool gap in the direction install can be around flexible prevent the piece of clamp, prevent the front end of clamp for being used for the card income wedge head of saw gap.
As a preferred technical scheme of the utility model, the rear side of the tight piece of back clamp is fixed with the pneumatic cylinder, and the pneumatic cylinder has the telescopic piston rod, piston rod and anti-pinch block fixed connection.
As an optimized technical scheme of the utility model, the guide way is extended around having seted up on the lateral wall of tool retracting seam, prevents clamp splice and guide way direction cooperation.
As an optimal technical scheme of the utility model, install the inductor that is used for detecting anti-pinch block position on the back clamp block.
The utility model has the advantages that: the utility model discloses in, prevent pressing from both sides the piece with the saw bit and establish inside the tight piece of back clamp of work piece, utilized the back on the tight piece of back clamp to move back the position characteristics of sword seam just to the saw seam, prevent that the piece of clamp can directly withstand the saw seam after stretching out, prevent that the saw seam from warping and hitting high-speed rotatory saw bit, improved the life of saw bit, the saw bit prevents that clamp device overall structure is compact in addition, it is few to occupy the exterior space, it is comparatively convenient to carry out the structure change on current sawing machine.

Detailed Description
The technical solution of the present invention will be described in detail by the following specific examples.
In a vertical circular saw machine, a circular saw blade is mounted on a head and is fed in a horizontal direction along with the head. As shown in fig. 1 to 2, the workpiece is positioned on a support table 5 during processing, movable clamps are arranged on the front side and the rear side of the workpiece with the feeding direction as the front, the movable clamps comprise a front clamping block 3 and a rear clamping block 1, the front clamping block 3 can move backwards, and the rear clamping block 1 can move forwards on the support table 5, so that the workpiece is clamped. The rear clamping block 1 is provided with a tool withdrawal slit 10, an anti-clamping block 2 which can stretch back and forth is installed in the tool withdrawal slit 10 in a guiding mode, and the front end of the anti-clamping block 2 is a wedge-shaped head 20 used for being clamped into a saw slit. In this embodiment, the movable clamp is specifically a pair of movable vices. The starting point of the anti-clamping block 2 is positioned at the rear end of the tool withdrawal slit 10.
As an optimal technical scheme of the utility model, the rear side of back clamp piece 1 is fixed with pneumatic cylinder 4, and pneumatic cylinder 4 has telescopic piston rod 40, piston rod 40 with prevent pressing from both sides 2 fixed connection of piece.
As an optimized technical scheme of the utility model, the lateral wall of the tool retracting seam 10 is provided with the front and back extending guide groove 11, and the clamping prevention block 2 is matched with the guide groove 11 in a guiding way.
As the utility model discloses an optimal technical scheme installs the inductor that is used for detecting to prevent pressing from both sides the piece position on the tight piece 1 of back clamp, senses at the inductor and prevents that the clamp splice retreats to the initial point after, and the saw bit returns the initiating point.
In other embodiments, the telescopic function of the anti-clamping block can also be realized by adopting a screw and nut mechanism, and the position of the anti-clamping block is controlled by a hand wheel. In other embodiments, the knife-withdrawing slit is wide enough to directly serve as a guide groove of the anti-clamping block.
The utility model discloses a theory of operation: in the sawing process, a saw blade is fed to a certain distance to form a saw gap, the hydraulic cylinder drives the front end wedge head of the anti-clamping block to be inserted into the saw gap, the saw blade stops running until a workpiece is sawed off, the anti-clamping block returns to the rear starting point, and the machine head drives the saw blade to return to the starting position after the sensor senses that the anti-clamping block returns.
The utility model relates to a circuit connection is the conventional means that technical staff in the field adopted, belongs to the widely used prior art. Components not described in detail herein are prior art.
Although the present invention has been described in detail with reference to the specific embodiments, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge range of those skilled in the art, and modifications or variations without creative efforts are still within the scope of the present invention.
