Description

Punching and tapping module of wiring cassette processing machine tool

Technical Field

The utility model belongs to the field of manufacturing of wiring cassettes, and particularly relates to a wiring cassette processing machine tool and a punching and tapping module thereof.

Background

In building engineering or various decoration construction, in order to connect various cables in a room, a groove is usually required to be formed in a wall body, then a wiring cassette is fixed on the groove, and the wiring cassette can play roles of connecting wires, being used as transition of various electric appliance circuits and protecting circuit safety simultaneously, and wiring operation can be completed in the cassette.

The wiring cassette is generally a rectangular box body with an opening, and is composed of a bottom plate and a plurality of side plates connected with the bottom plate, wiring holes, threaded holes for subsequent installation, mounting lugs and other relatively small structures are formed in the side plates and the bottom plate, so that the one-time processing forming of the wiring cassette is very difficult to work, at present, equipment special for processing the wiring cassette is basically not available on the market, and the plates are spliced together to form the wiring cassette in a mode of welding and the like after being respectively processed, so that time and labor are wasted.

In the prior art, the functions and the structures of the junction box are similar, and the difference is that the junction box is mainly used for installing various switches and sockets and other wiring panels for electrical appliances, and is generally installed outside a building surface; the wiring cassette is generally required to be pre-buried for installation in order to keep the building surface clean and beautiful. Then, although in actual production, the production equipment for manufacturing the junction box cannot be used for manufacturing the junction box, it is assumed that in theory, the equipment for manufacturing the junction box can be used for manufacturing the junction box after being partially modified, and the manufacturing method of the junction box can include the following two methods: (1) Firstly, assembling a plurality of flat plates into a rectangular box body with an opening, and performing operations such as drilling, tapping and the like on each surface of the box body through equipment such as a machine tool and the like to form a finished wiring cassette; (2) injection molding by an injection mold.

For example, the Chinese patent application number is: CN201621471334.8, publication date: patent literature of 2017, 8 and 29 days discloses a special machine tool for machining a motor junction box, which has the technical scheme that: the automatic wire cutting machine comprises a machine body, wherein a rotating disc and a driving motor for driving the rotating disc to rotate are arranged on the machine body, at least three workpiece fixing devices are uniformly distributed on the upper surface of the rotating disc around the rotating shaft of the rotating disc, and a drilling device and a tapping device for processing the end face of a junction box are further arranged above the rotating disc and correspond to two adjacent workpiece fixing devices respectively. In the process of machining the junction box, an operator can take down the machined junction box and replace the junction box to be machined, and the junction boxes are replaced one by one and are continuously circulated to carry out line production. However, in this solution, before the operations of drilling and tapping the junction box, the device in the pre-process is required to manufacture the box body of the junction box, and this two-stage machining requires a certain intermediate time, so that the machining efficiency is not particularly ideal. In addition, because the area of the rotating disc of the machine tool in the scheme is fixed, the number of the workpiece fixing devices on the rotating disc cannot be set too much, and when the workpiece devices on the rotating disc are processed, the junction boxes on the rotating disc are required to be detached one by one and then replaced by the junction boxes to be processed, so that the time is long, and the processing efficiency is further reduced.

For another example, chinese patent application No.: CN201620330313.8, publication date: the special literature of 2016, 11 and 23 discloses a junction box production module, which comprises a blanking die, an injection die, a trimming die, a side punching die and an edging die; the injection mold comprises a main frame, an upper mold unit and a lower mold unit, wherein the upper mold unit and the lower mold unit are arranged on the main frame; the upper die unit comprises an upper injection molding die capable of moving up and down, an injection molding piece connected to the middle part of the upper injection molding die and an upper die driving piece used for driving the upper injection molding die to move up and down; the lower die unit comprises a lower injection molding die, a matched plastic box cavity which is arranged on the lower injection molding die and can be matched with the injection molding piece for injection molding the junction box body, and a first wire clamping groove and a second wire clamping groove which are arranged on the left side and the right side of the matched plastic box cavity and can be used for accommodating wires; and a matched injection molding assembly capable of limiting and tensioning the lead when the upper injection molding die is pressed down is arranged between the upper injection molding die and the lower injection molding die. Although the utility model has simple structure, can effectively tighten and limit the wires, prevent the wires from bending or moving in the injection molding process, and ensure the sealing property of the injection molding of the junction box, the molding time required by the manufacture of the junction box by the module is longer, the time spent on the treatment of injection molding raw materials is longer, and the processing efficiency of the whole module for manufacturing the junction box is not high.
