Detailed Description
The present invention will be further described with reference to the following examples and the accompanying drawings.
Example 1
The invention discloses a lifting type protective cover for a woodworking circular saw, which comprises a protective cover shell, a support, a bolt and a limiting pin.
The working principle of the lifting of the protective cover of the invention is as follows: before the plate is sawed, the protective cover is always in a falling state, and the saw blade is completely covered by the protective cover in a closed manner. When the machine starts to saw, the wood board moves forwards on the workbench and touches the slope surface of the housing, the housing moves upwards integrally under the action of the forward thrust of the processed wood board 10 and the sliding groove, the lower bottom surface of the housing is always combined with the wood board surface, the scattering of wood chips is effectively controlled, and when the wood board is removed from the protective cover after each sawing, the protective cover automatically falls down, so that the full-protection coverage of the exposed saw blade is ensured.
The invention discloses a method for manufacturing a lifting protective cover for a woodworking circular saw, which comprises the following steps:
and a, manufacturing a protective cover shell.
Referring to fig. 1 and 2, fig. 1 is a schematic view of a protective casing according to an embodiment of the present invention, and fig. 2 is a top view of fig. 1. As shown in the figure, the protective housing 1 is made of a steel plate with the thickness of 1.5mm, and is formed into a housing with closed surfaces except for an open lower bottom through scribing, cutting, bending and welding, wherein one side surface of the housing which can be turned into a cover is made into a slope surface with an included angle of 30 degrees with the working table surface 6. The width of the top plate of the protective housing 1 is 100 mm. The height of the side plate of the protective cover is 150 mm. The included angle Q is 30 degrees.
And step b, forming a long white hole (a chute 3) with the width of 10mm and the length of 100mm at the joint of the formed housing and the fixed support 2.
Fig. 3 is a schematic structural diagram of a bracket according to an embodiment of the invention. The support 3 is a rectangular steel plate with the thickness of 3mm, a bolt hole 8 is formed in the upper end of the rectangular steel plate, and the lower end of the rectangular steel plate is welded with a working table top or a metal component on the lower portion of the working table top or is fixedly connected through a bolt 4.
And c, opening a safety limit pin hole with the diameter of about 5mm beside the chute at the lower part of the housing.
D, cutting the fixed support into a rectangular steel plate 9 by using a steel plate with the thickness of 3mm, and forming a bolt mounting hole with the diameter of 10mm at the upper end, wherein the bolt for fixing the housing can be a finished product.
Example 2
Fig. 4 is a schematic structural diagram of a protective cover according to an embodiment of the present invention. The invention discloses a method for installing a lifting type protective cover for a woodworking circular saw, which comprises the following steps:
step a, installing a housing fixing support: the steel plate plane of the housing fixing support and the saw blade plane are required to be on the same horizontal straight line, and the lower end of the housing fixing support is welded or connected and fixed with the working table top or a metal component on the lower portion of the working table top by bolts.
Step b, installing a housing and a fixed support: the end of the chute arranged on the housing is sleeved into the upper end of the fixed support according to the figure I, so that the chute is aligned with the bolt hole and then penetrates through the bolt with the length of 8mm and 27mm, the bolt is fixed by double nuts, the proper distance between the support and the housing is ensured by adjusting the screwing degree of the nuts, and the requirement that the housing slides up and down on the support without being blocked or loosened is met.
Step c, installing a limiting pin: after the protective cover is installed, a pin with the diameter of 4mm is inserted into the limiting pin hole, and the pluggable pin can prevent the saw disc from being manually turned over when the saw disc works.
The lifting type protective cover for the woodworking circular saw has substantive characteristics and obvious technical progress, can realize effective isolation of operators and the circular saw, ensures the operation safety of the operators, and reduces potential safety hazards. Fig. 5 is a schematic view of a protective cover in use according to an embodiment of the present invention.
