Description

Slotting machine

Technical field

The invention belongs to the Machining Technology field, particularly relate to a kind of slotting machine.

Background technology

Number be a kind of brass instrument, be divided into trumpet, medium size, trombone and embrace number etc. multiplely, mainly form by number mouth, body and mechanical three parts.Its middle tube body is to be connected through a bend pipe by two long tubes to constitute.Bend pipe method for processing forming commonly used at present is as pipe with brass sheet; At first on bender, the center is bent certain angle; Then on the shaping device the uneven place on the bending part being pressed into arc surface with its leveling, the bend pipe two-port edge after utilizing slotting machine flatten is at last cut to put down and is got final product.But the shortcoming of slotting machine commonly used is a complex structure at present, the high and operation inconvenience of cost.

Summary of the invention

In order to address the above problem, the object of the present invention is to provide a kind of simple in structure, decorative pearl on top of an official cap machine that cost is low and easy to operate.

In order to achieve the above object, slotting machine provided by the invention comprises bearing, counterdie, patrix, bracing frame, oil cylinder, two slide rails, gripper shoe, motor and blades; Wherein bearing is installed on the ground; Counterdie is installed in the surperficial front end of bearing, and its centre of surface is recessed to form a hole that is provided with that is used for the horizontal positioned bend pipe, and this end that hole is set extends rearward to the back edge of counterdie; It is L shaped that bracing frame is, and its lower end is installed in the front portion of bearing, and the upper level position is positioned at the top of counterdie simultaneously; Oil cylinder is vertically mounted on the top of bracing frame, and its piston rod down; Patrix is installed in the piston-rod lower end of oil cylinder, and is positioned at the top of counterdie, and also be recessed to form on its bottom surface one with counterdie on the corresponding hole that is provided with, hole is set; Article two, slide rail is arranged on the surperficial rear portion of bearing along horizontal standoff distance; Gripper shoe is installed on two slide rails with the mode of sliding; Motor is arranged on the gripper shoe, and its output shaft forward; Blade is installed on the output shaft of motor, and near the open rearward end that the hole is set on the counterdie.

Described gripper shoe also is equipped with screw mandrel, screw on the bottom surface, and the outer end of screw mandrel is connected with a crank or a motor that is used to drive the screw mandrel rotation.

Slotting machine provided by the invention is a kind of pipe fitting apparatus for shaping, and it can cut the pipe fitting edge flat fast.This device have structural design simple, rationally, cost is low, and is convenient to advantage such as operation.

Description of drawings

Fig. 1 is a slotting machine forward structure sketch map provided by the invention.

Fig. 2 be among Fig. 1 A-A to cutaway view.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment slotting machine provided by the invention is elaborated.

Like Fig. 1-shown in Figure 2, slotting machine provided by the invention comprises bearing 1, counterdie 2, patrix 3, bracing frame 4, oil cylinder 5, two slide rails 6, gripper shoe 7, motor 8 and blades 9; Wherein bearing 1 is installed on the ground; Counterdie 2 is installed in the surperficial front end of bearing 1, and its centre of surface is recessed to form a hole that is provided with that is used for the horizontal positioned bend pipe, and this end that hole is set extends rearward to the back edge of counterdie 2; Bracing frame 4 is L shaped, and its lower end is installed in the front portion of bearing 1, and the upper level position is positioned at the top of counterdie 2 simultaneously; Oil cylinder 5 is vertically mounted on the top of bracing frame 4, and its piston rod down; Patrix 3 is installed in the piston-rod lower end of oil cylinder 5, and is positioned at the top of counterdie 2, and also be recessed to form on its bottom surface one with counterdie 2 on the corresponding hole that is provided with, hole is set; Article two, slide rail 6 is arranged on the surperficial rear portion of bearing 1 along horizontal standoff distance; Gripper shoe 7 is installed on two slide rails 6 with the mode of sliding; Motor 8 is arranged on the gripper shoe 7, and its output shaft forward; Blade 9 is installed on the output shaft of motor 8, and near the open rearward end that the hole is set on the counterdie 2.

Described gripper shoe also is equipped with screw mandrel, screw on 7 bottom surfaces, and the outer end of screw mandrel is connected with a crank 10 or a motor that is used to drive the screw mandrel rotation.

Existing slotting machine operation principle provided by the invention is described: at first put into the hole that is provided with on the counterdie 2 by the bend pipe level of staff after with bending and shaping; And make an end of treating otch on the bend pipe be exposed at the outside that open rearward end on the hole is set; Start not shown oil pump then; Under the effect of oil pump; Hydraulic oil from hydraulic system will enter into the upper chamber inside of oil cylinder 5 through oil pipe, thereby piston rod and patrix 3 on it are together moved down, and hold out against counterdie 2 up to patrix 3.Starter motor 8 is so that blade 9 rotation at a high speed afterwards; Shake 10 or start not shown screw mandrel drive motors with hand by the staff then; So that gripper shoe 7 is moved from a side direction opposite side of slide rail 6; In this process, high speed rotation of blade 9 will contact with the outer end of bend pipe, thereby cut its edge flat.Control oil pump then so that hydraulic oil gets into the lower cavity inside of oil cylinder 5, thereby piston rod and patrix 3 on it are together moved up, just can the bend pipe behind the otch be taken out from counterdie 2 afterwards, accomplish the otch process of bend pipe thus.
