A mold-locking device for a high-speed precision punch press

Abstract

This utility model relates to the field of high-speed punch presses and discloses a mold-locking device for a high-speed precision punch press. The device includes a punch press processing table with two symmetrically arranged movable seats on its top. Each movable seat has a groove on its opposite side, and a rotating groove is symmetrically formed on the inner wall of each groove. A clamping rotating plate is arranged within the inner cavity of each rotating groove. The clamping rotating plate is rotatably positioned within the inner cavity of the rotating groove via a rotating shaft. In this high-speed precision punch press mold-locking device, after the mold to be locked is placed on the punch press processing table, a servo motor is activated to drive a bidirectional lead screw to rotate, thereby causing the movable block in the movable groove to move. As the movable seat moves, the clamping rotating plate first contacts both sides of the mold. In conjunction with the rotating groove and rotating shaft within the groove, the clamping rotating plate drives an L-shaped clamping plate to rotate and clamp the mold from both ends, thus stably locking the punch press mold. This solves the problem of existing mold-locking devices being difficult to conveniently fix according to mold dimensions.

It includes a punch press processing table, a mold locking mechanism is provided on the upper side of the punch press processing table, and a disassembly mechanism is provided in the middle of the upper side of the punch press processing table. The mold locking mechanism includes a first lead screw and a second lead screw. This device can lock the mold, and the mold is easy to disassemble, which improves the mold changing efficiency and has strong practicality.

[0004] However, this device limits the mold by using the first and second positioning plates and the first and second locking pins. Due to the presence of the locking pins, it can only lock molds of a fixed size. If it is to be compatible with a variety of molds, multiple positioning plates and locking pins need to be made, which greatly increases the cost of using this mold locking device. To address this, a mold locking device for a high-speed precision punch press is proposed to solve the problem that existing mold locking devices are difficult to fix conveniently according to the mold size.

The mold-locking device of this high-speed precision punch press, after clamping and limiting the punch press mold through the clamping rotating plate and L-shaped clamping plate, rotates the top plate by adjusting the column to rotate the pressure block to a suitable position on the top of the mold. Then, the handwheel is adjusted to drive the limit screw to rotate, thereby driving the pressure block to move down to press and limit it from the mold. The stabilizing ring and support plate are used to increase the firmness of the fixed top plate, further improving the stability of the mold after the mold is locked by this mold-locking device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figure 1-4 A mold-locking device for a high-speed precision punch press includes a punch press processing table 1. Two movable seats 2 are symmetrically arranged on the top of the punch press processing table 1. Grooves 3 are opened on opposite sides of the movable seats 2. Rotary grooves 4 are symmetrically opened on the inner walls of the grooves 3. A clamping rotating plate 5 is arranged in the inner cavity of the rotating groove 4. The clamping rotating plate 5 is rotatably arranged in the inner cavity of the rotating groove 4 via a rotating shaft 6. An L-shaped clamping plate 7 is fixedly connected to one end of the clamping rotating plate 5. A limit clamping mechanism 8 is provided on the top of the movable seats 2. A movable groove 9 is opened on the top of the punch press processing table 1. A movable block 10 is slidably arranged in the inner cavity of the movable groove 9. A bidirectional lead screw 11 is arranged in the inner cavity of the movable groove 9. A servo motor 12 is fixedly connected to one side of the punch press processing table 1.

[0022] Furthermore, the surfaces of the clamping plate 5 and the L-shaped clamping plate 7 are roughened, and the rotating shaft 6 is made of high-strength steel.

[0023] Furthermore, the bidirectional lead screw 11 passes through the punch press processing table 1, and the two are rotatably connected by a bearing at their intersection. The output shaft of the servo motor 12 is fixedly connected to the bidirectional lead screw 11.

[0024] Furthermore, the movable block 10 is fixedly connected to the movable seat 2, and the bidirectional lead screw 11 passes through the movable block 10 and the two are threaded together. The bidirectional lead screw 11 is driven to rotate by the servo motor 12, which in turn drives the movable block 10 in the movable groove 9 to move inward. As the movable seat 2 moves inward, the clamping rotating plate 5 first contacts the two sides of the mold. In conjunction with the rotating groove 4 and rotating shaft 6 in the groove 3, the clamping rotating plate 5 drives the L-shaped clamping plate 7 to rotate and clamp the mold from both ends, thus stably locking the punch mold.

[0025] Furthermore, the limiting and pressing mechanism 8 includes an adjusting column 801 that penetrates the inner wall of the movable seat 2. The adjusting column 801 and the movable seat 2 are limited by a bearing and are rotatably connected. A fixed top plate 802 is fixedly connected to the top of the adjusting column 801.

[0026] Furthermore, a pressure block 803 is provided at the bottom of the fixed top plate 802, and a limit stud 804 is fixedly connected to the top of the pressure block 803. The limit stud 804 penetrates the fixed top plate 802 and the two are threadedly connected. An adjusting handwheel 805 is fixedly connected to the top of the limit stud 804.

[0027] Furthermore, the outer ring of the adjusting column 801 is rotatably connected to a stabilizing ring 806. The stabilizing ring 806 is rotatably connected to the movable seat 2. The outer ring of the stabilizing ring 806 is inclined and fixedly connected to a support plate 807. The support plate 807 is fixedly connected to the fixed top plate 802. After the punch mold is clamped and limited by the clamping rotating plate 5 and the L-shaped clamping plate 7, the pressure block 803 is rotated to a suitable position on the top of the mold by rotating the fixed top plate 802 through the adjusting column 801. Then, the limiting stud 804 is rotated by adjusting the handwheel 805, which in turn moves the pressure block 803 down to be pressed and limited by the mold. The stabilizing ring 806 and the support plate 807 increase the firmness of the fixed top plate 802, further improving the stability of the mold after the mold is locked by this mold locking device.

[0028] Working principle: When using the mold locking device of this high-speed precision punch press, after placing the mold to be locked on the punch press processing table 1, the servo motor 12 is turned on to drive the bidirectional lead screw 11 to rotate, which in turn drives the moving block 10 in the moving groove 9 to move. During the movement of the moving seat 2, the clamping rotating plate 5 first contacts the two sides of the mold. With the cooperation of the rotating groove 4 and the rotating shaft 6 in the groove 3, the clamping rotating plate 5 drives the L-shaped clamping plate 7 to rotate and clamp the mold from both ends, thus stably locking the punch press mold. This solves the problem that existing mold locking devices are difficult to adjust according to the mold. The device addresses the issue of convenient size fixation. After the punch mold is clamped and limited by the clamping rotating plate 5 and the L-shaped clamping plate 7, the top plate 802 is rotated by the adjusting column 801 to rotate the pressure block 803 to a suitable position on the top of the mold. Then, the limiting screw 804 is rotated by the adjusting handwheel 805, which in turn moves the pressure block 803 down to be pressed and limited by the mold. The top plate 802 is fixed by the stabilizing ring 806 and the support plate 807, which further improves the stability of the mold after the mold is locked by this mold locking device.
