Problems solved by technology

[0004] Due to the special shape of the fishplate slab and many sides, it is usually only possible to process each side of a single fishplate slab one by one during processing, which makes the process steps of manufacturing the fishplate from the fishplate slab cumbersome. , which increases the circulation times of fishtail slabs in the processing workshop, which limits the improvement of processing efficiency

Embodiment

[0055] A fishplate processing technology, with reference to Figure 4 , which includes the following steps:

[0056] Cut off:

[0057] Cut the blank to obtain a fishtail slab 1 with a length of 835+2 mm, and the shape of the fishtail slab 1 is as follows figure 1 shown.

[0058] Milling face:

[0059] With the aid of a milling machine, turn and mill the cross-sections at both ends of the length direction of the cut fishtail slab 1 until it is smooth, and control the length of the fishtail slab 1 after turning and milling to be 835+1mm.

[0060] Milling large sides:

[0061] The first turning and milling equipment is used to simultaneously turn and mill the two sides 11 of the fishtail slab 1 that has been milled over the end face until the distance between the two sides 11 is 40±0.2mm.

[0062] refer to Figure 5 , the first turning and milling equipment includes a first workbench 3 , a first slab fixing tool set on the first workbench 3 , and first racks 31 symmetricall...

Abstract

The invention discloses a fishplate machining technology, and belongs to the technical field of fishplate machining. According to the technical scheme, the fishplate machining technology comprises thesteps of sawing, end surface milling, large side surface milling, first inclined surface milling, second inclined surface milling, rounding, drilling and the like, and has the advantage of being highin turning milling machining efficiency. In the preferred scheme, the boss milling step is included, a fishplate obtained through machining has the characteristics of being low in self weight and convenient to carry and install, the tensile strength reaches 935 MPa, the lower yield strength is 623 MPa, and the performance of the obtained fishplate is equal to that of a common fishplate. In a further preferred scheme, the large side surface milling step is completed through first turning milling equipment, and the two large side surfaces of a fishplate blank can be subjected to turning millingat the same time; and the first inclined surface milling step is completed through second turning milling equipment, multiple fishplate blanks can be subjected to turning milling at the same time, the fishplate machining efficiency is greatly improved, and inconvenience and labor wasting which are caused by the mode that workpieces are machined one by one, and the circulating number of times is large are reduced.

Description

technical field [0001] The invention relates to the technical field of fishplate processing, more specifically, it relates to a fishplate processing technology. Background technique [0002] The fish plate, commonly known as the splint, acts as a connection at the joint of the track, and is a connecting fastener used for the connection between the track and the track. It is usually made of blank slabs, which are processed by turning, grinding and other processes on each side of the slabs according to a certain processing sequence. [0003] figure 1 What is shown is a fishplate slab 1 used for processing fishplates in the prior art. The two ends of the main body are roughly trapezoidal in shape, and it also includes two parallel large sides 11 and two mirror-symmetrical Slope side 12. The middle part of the wider side 11 is provided with a through groove 13 along the length direction of the fishplate 2 , so that two ribs 14 are formed on the side of the wider side 11 of th...
