one. introduction
Mortise and groove machining center is a new type of machine created in recent years, which is specially designed for antique furniture, furniture manufacturing in Ming and Qing Dynasties, ancient buildings and other products with traditional cultural charm.
The top of Chinese furniture is the Ming and Qing Dynasties. As a historical and cultural symbol of a dynasty, its furniture reflects the aesthetic characteristics of the perfect integration of life philosophy and historical culture at that time. This philosophy is reflected in its shape and structure.
A lot of Ming-style furniture uses round materials to make it bend with degrees, delicate and smooth, reflecting the beauty of curves like flowing clouds and flowing water.
In addition to the soft curve shape, the most admirable thing in Ming and Qing furniture is its tenon-and-mortise structure. The ancients said: “The tenon and tenon will be locked for ten thousand years.” The object can be firmly formed without nails and glue. This structure not only conforms to the principles of mechanics but also attaches great importance to practicality and beauty, which is consistent with the traditional philosophy of “harmony between man and nature”.
The production process of mortise and groove machining center is more beautiful and elegant and tends to be high-end. However, this type of product is also very complicated to make, and the raw materials of this type of product are also very precious, usually mainly imported wood.
As the basic joint method of frame structure furniture – mortise and tenon joints, the corresponding parts of the jointed parts have three key points: tenon, tenon, tenon and groove.
Two. Mortise and groove machining center tenon processing
The tenon refers to the protruding part of the utensil that is connected by the concave and convex.
Mortise and groove machining center The tenon production should adopt the principle of the base hole system, that is, the tenon parameters should be adjusted based on the matching mortise size when making the tenon, so that the tenon and the mortise have the specified tolerance and cooperation, so as to obtain the Interchangeable parts.
1. Production of right-angle square tenon and dovetail tenon
Right-angle square tenons can be made on single- or double-head tenoning machines. Mortise and groove machining centers use milling cutters with cutters, grooving cutters or disc cutters, etc., or they can be processed directly on milling machines.
For right-angle multi-head tenon with large sheet width, it can be processed with a multi-piece grooving cutter on a right-angle box tenoning machine.
2, the production of long round tenon
The oblong tenon is also called the oval tenon, which is processed by a special oblong tenoning machine.
3. Round rod tenon production
Mortise and groove machining center requires special equipment to make round tenon, namely round tenon machine and round tenon cutting machine. When making with a round bar machine, it is required to prepare the raw material into a slender square material. The round bar produced is in the shape of a long strip, which needs to be cut and processed by a special round bar cross-cutting machine.
Three. Mortise and groove machining center mortise processing
Matching with mortise, mortise is divided into square mortise, oblong mortise, dovetail mortise and round mortise.
1. Rectangular mortise production
Rectangular mortise is also known as right-angle mortise. The commonly used processing equipment is a punching machine, which is processed by using a square hollow drill sleeve and a twist drill core. Commonly used drill sleeve specifications are 6mm, 8mm, 9.5mm, 12mm, 13mm, 15mm, etc.
2. Making of oval mortise
The oval mortise is mostly produced by special oval mortise processing equipment, of which the most commonly used is the horizontal double-end tenon and groove machine. Only one mortise can be machined at a time.
Mortise and groove machining centers often use horizontal multi-axis drilling and milling machines when there are multiple long and tenon holes of the same size on the same axis.
3. Round mortise production
Round mortise, commonly known as round hole, is an important way to connect furniture. It is mainly used as a round rod tenon and a mounting hole for hardware connectors.
For round hole processing, different machine tools and drills should be selected according to the specifications of the round holes, the material of the parts, the shape and specifications of the parts, and the drilling position.
Four. Mortise and groove machining center tenon and groove machining
In the production of solid wood furniture, the vertical and horizontal connections of square materials are often connected by tenon and mortise, while the vertical connection is usually connected by tenon and groove and tenon spring, and the horizontal connection along the width is often connected by notch.
Generally speaking, the tongue-and-groove fit along the fiber direction is commonly known as tongue-and-groove and tongue spring, the tongue-and-groove in the transverse fiber direction is commonly known as a notch or a notch, and a partial non-penetrating notch is commonly called a notch.
1. Planer
Four-sided planer is the most commonly used equipment for producing tongue and groove in mortise and groove machining center. It is mainly used to produce longitudinal through grooves, which is the most common tongue and groove connection method in furniture production.
Since the four-sided planer can generally only process the through grooves in the length direction of the part, for the parts that need to be tenoned at the end of the door frame, it is usually necessary to customize a pair of matching male and female knives.
2. Milling machine
The corresponding tenon-making disc cutter is installed on the vertical shaft, and the tenon and groove can be cut out on the side or end of the square material. The depth of the tenon and groove can be controlled by adjusting the protrusion of the cutter relative to the guide ruler.
For dovetail tenon and inner hollow tenon and groove, it is usually difficult to process with other equipment. In this case, it is generally necessary to customize a shank milling cutter corresponding to the groove and use a router to work.
3. Circular saw machine
Due to the thin thickness of the circular saw blade, the slotted opening is generally 3~5mm through the narrow slot.
Due to the large diameter of the circular saw blade, the adjustment range of the notch depth is large, which is suitable for the processing of various types of notches and gaps, and the edge of the saw edge is of good quality and is not easy to chip.
As a mortise and groove machining center manufacturer, China shi kai niu mainly produces tenon tenoners, including square tenon tenoners, long and round tenoners, vertical axis machines, and routers. Less efficient or less accurate.
The forming of tenon and tenon groove directly affects the processing quality of solid wood workpieces. During the processing of the mortise and groove machining center, it is required to control the distance between the two tenons and the angle between the cheek and the shoulder of the tenon;
When tenoning at both ends, the same surface should be used as the reference; when placing parts, there should be no debris between the reference surfaces.
Tenon and tenon and groove can be processed by sawing and milling, which are often done on milling machine and tenon or tenon and groove machine; frame tenon and finger joint can generally be processed on milling machine, and box tenon and dovetail tenon are processed on tenoning machine.
five. Mortise and groove machining center Features
1. System aspects
The mortise and groove machining center adopts the control template of Taiwan Yitu, which uses the model space control system. Such a system is intuitively displayed and convenient for most people to operate. It is much simpler than the control mode of simply filling in the form.
2. Accessories
The mortise and groove machining center also uses servo motors, Taiwan sliders, and guide rails, which can be more suitable for coordination with the Taiwan system, and the stability can be greatly improved.
3. Match
China mortise and groove machining center is a machine that can make a variety of tenons, so the machine needs some auxiliary movable accessories to help the system to optimize the tenon production. Workers can manually adjust the console. In order to facilitate the workers to use the machine accurately, there is a small angle measurer next to the working platform.
4. Mechanical lubrication
The lubrication system is an indispensable part. This machine has a complete lubrication system. What needs to be done is to ensure that there is always lubricating oil in the oil pot, because the oil pot of the mortise and groove machining center is a power oil pot with automatic oiling. . This can also relatively reduce the labor force of the master worker.
