Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments. It is to be understood that the following description is only for purposes of clearly illustrating the present invention and is not to be taken in a limiting sense.

The brake plate (8 × 3000 × 24000mm in size) used in a steel plant will be described below with reference to the accompanying drawings.

A batch drilling method for crane beam brake plates of industrial plants is implemented through the following steps:

step 1: according to the size of the brake plate of 8 multiplied by 3000 multiplied by 24000mm, the whole raw material plate 1 is the checkered plate of 8 multiplied by 1500 multiplied by 8000mm, the quality of the checkered plate is checked before entering the field, and the checkered plate can enter the field to be put into use after being checked to be qualified.

Step 2: the method comprises the steps of manufacturing a fetal membrane 2 with the length of 8000mm, wherein the thickness of the fetal membrane is 12-22 mm, selecting the thickness of the fetal membrane 2 to be 16mm in the example, drilling holes in the fetal membrane 2 along the length direction according to the set pitch of the drawing, ensuring the pitch of the holes to be accurate, and meeting the requirements of the design drawing, as shown in figure 1.

And step 3: the fixture is manufactured according to the principle of a screw jack and is made of a U-shaped clamping plate 3, a screw handle 4 and a nut 5. The length of two side arms at the opening end of the U-shaped clamping plate 3 has a difference, an M30 nut parallel to the length direction of the longer side arm is welded at one end of the shorter length, the screw handle 4 is made by welding a cylindrical handle at one end of an M30 screw 6, the screw 6 of the screw handle 4 is screwed into the nut 5 to form a whole body, and the whole raw material plate 1 clamped between the U-shaped openings is fastened as shown in figure 2. When the fixture is used, the threads can be lubricated by glycerol to reduce resistance. The distance between the openings of the U-shaped clamping plates 3 is larger than the length of the drill bit, so that as many raw material plates as possible can be placed under the condition that the conditions are met.

And 4, step 4: the number of the raw material plates 1 drilled at each time was determined according to the length of the drill and the thickness (8 mm) and the thickness (16 mm) of the raw material plate 3, and in this embodiment, the number of raw material plates to be drilled in batch was calculated to be 7.
