Description

Numerical Control Turrent Punch Press Inclined Wedge Type Drive Unit

Technical field

The utility model relates to a kind of transmission device of NC turret punch machine, and particularly a kind of Numerical Control Turrent Punch Press Inclined Wedge Type Drive Unit belongs to the punching press field.

Background technology

The existing main drive of numerical control press mainly contains two kinds of mechanical main transmission and hydraulic pressure main transmissions.For mechanical main drive, its structure mainly is made up of attacking head, slide block, connecting rod, bent axle, flywheel, clutch, controller and motor etc., described attacking head is assemblied in the slide block lower end, the installing hole that attacking head passes capstan head is contained in the top of patrix, upper end of slide block is connected the connecting rod lower end by pin, and small end is contained on the bent axle, and bent axle passes frame and is connected with flywheel through clutch, flywheel shaft is connected with motor through belt or chain, and clutch is controlled by the controller.Because attacking head is by Motor Drive by connecting rod, bent axle and clutch, so obviously there are following several point defects: 1, because attacking head is interrupter duty, and motor and flywheel are continuous operations, so, the control action of clutch and brake is frequent, its maximum punching frequency can reach per minute 300 times, makes the fault rate height of control assembly; 2, the motor because the use common electric machine is decided, thereby its punching frequency is changeless, has significant limitation; 3, be by the decision of the offset of bent axle, so its punching stroke is also non-adjustable because of its punching stroke; 4, because motor speed is constant, and when lathe did not carry out punching press, motor drove flywheel work as usual, energy loss is big; 5, because parts such as flywheel, clutch and controller are installed, make the complex structure of main drive, install, adjust and the maintenance inconvenience.

For the hydraulic pressure main drive, its structure is mainly by attacking head, slide block, slider guide seat and hydraulic pressure main transmission part are formed, drive slide block by the hydraulic pressure main transmission part and slide up and down the attacking head work that makes along the slider guide seat, its punching frequency and punching stroke all can be regulated by the hydraulic pressure main transmission part, has the wide advantage of the scope of application, but because of the hydraulic pressure main transmission part is to carry out work by hydraulic oil, need with hydraulic systems such as hydraulic pump and fluid pressure lines supporting with it, and the fluid pressure line of hydraulic system and Hydraulic Elements are more, be easy to generate leakage phenomenon, cause environmental pollution, increase maintenance workload.Because of the at present main dependence on import of hydraulic pressure main transmission part, cost is more much higher than mechanical main transmission NC turret punch machine, is unfavorable for generally using at home again.

Summary of the invention

The purpose of this utility model is: at the problem of existence in the transmission device use of present NC turret punch machine, provide a kind of inclined wedge type transmission device of NC turret punch machine.

The purpose of this utility model is achieved in that a kind of Numerical Control Turrent Punch Press Inclined Wedge Type Drive Unit, comprise positioning sliding block, it is characterized in that: the declivity contract is equipped with on positioning sliding block top, the inclined-plane of declivity contract contacts with the inclined-plane of last oblique contract, the top of going up oblique contract is provided with limited block, the bottom of declivity contract is provided with back-moving spring, goes up oblique contract and is provided with screw thread, and servomotor is by the threaded engagement on ball-screw and the last oblique contract.

Advantage of the present utility model is: owing to using servomotor to cancel clutch and parts such as controller and flywheel, its structure is than mechanical type main drive advantages of simple more; Owing to use servomotor, realized punching press frequency that the fluid pressure type main drive is had and the advantage that punching stroke all can be regulated arbitrarily and the punching press frequency is high, its cost is cheaper, and installation and maintenance are convenient; In actual use, reliability of the present utility model not only is higher than the NC turret punch machine that uses the mechanical type main drive, also is higher than the NC turret punch machine of fluid pressure type main drive.

Description of drawings

Fig. 1 is a kind of example structure schematic diagram of the present utility model.

Among the figure: 1, positioning sliding block, 2, the declivity contract, 3, go up oblique contract, 4, back-moving spring, 5, limited block, 6, servomotor, 7, ball-screw, 8, universal joint.

The specific embodiment

The nonrestrictive structural representation of showing a kind of specific embodiment of the present utility model of accompanying drawing, the utility model will be further described below in conjunction with accompanying drawing.

As seen from Figure 1, the utility model is equipped with declivity contract 2 on positioning sliding block 1 top, the inclined-plane of declivity contract 2 contacts with the inclined-plane of last oblique contract 3, the top of going up oblique contract 3 is provided with limited block 5, the bottom of declivity contract 2 is provided with back-moving spring 4, go up oblique contract 3 and be provided with screw thread, servomotor 6 is by the threaded engagement on ball-screw 7 and the last oblique contract 3.In the present embodiment, be provided with universal joint 8 between servomotor 6 and the ball-screw 7.

In the use, upper trimming die is installed in the below of positioning sliding block 1, punching stroke of the present utility model is to realize by the rotational angle that changes servomotor 6, in the rotation, servomotor 6 drives ball-screw 7 and rotates synchronously, make oblique contract 3 that the left and right horizontal displacement take place by the screw thread that cooperatively interacts, under the effect of back-moving spring 4, declivity contract 2 will upper and lower displacement, the rotational angle of servomotor 6 is big more, it is long more to go up oblique contract 3 horizontal displacements distance, the distance of declivity contract 2 upper and lower displacements is long more, and punching stroke is just long more, otherwise then short, the length of punching stroke can be pressed on minimum lighting by last oblique contract 3 by declivity contract 2, adjusts in top offset touches the traveled distance of limited block 5 to declivity contract 2; Punching press frequency of the present utility model is consistent with the round rotational frequency of servomotor 6, when changing servomotor 4 rotational frequencies, has also just changed the punching press frequency.

Claims

1, a kind of Numerical Control Turrent Punch Press Inclined Wedge Type Drive Unit, comprise positioning sliding block, it is characterized in that: the declivity contract is equipped with on positioning sliding block top, the inclined-plane of declivity contract contacts with the inclined-plane of last oblique contract, the top of going up oblique contract is provided with limited block, the bottom of declivity contract is provided with back-moving spring, goes up oblique contract and is provided with screw thread, and servomotor is by the threaded engagement on ball-screw and the last oblique contract.
