Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a metal keel stamping die with replaceable patterns. Background Art

[0002] A die is various molds and tools used in industrial production to obtain required products by means of injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, etc. The die is used to make a blank into a workpiece with a specific shape and size under the action of external force. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, die casting, and the forming processing of compression molding or injection molding of products such as engineering plastics, rubber, and ceramics. The die has a specific contour or inner cavity shape. By applying the contour shape with a cutting edge, the blank can be separated along the contour line (blanking). By applying the inner cavity shape, the blank can obtain a corresponding three-dimensional shape. Generally, a die includes two parts, a moving die and a fixed die (or a convex die and a concave die), which can be separated and combined. The fixed die and the moving die are both applied in stamping and injection molding products.

[0003] The traditional stamping moving die is fixed on the stamping device in a fixed installation manner. A stamping device often can only use one kind of stamping moving die, and it is rather troublesome to replace. Especially for the embossing die, due to different patterns, it is often necessary to replace the moving die with another pattern for stamping. However, the traditional stamping device can only be replaced to another stamping device for embossing, with low efficiency, and it is particularly troublesome to replace the moving die, consuming time and effort. Therefore, it is necessary to redesign a metal keel stamping die with replaceable patterns to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the background art and propose a metal keel stamping die with replaceable patterns.

The output end of the driving device is symmetrically connected with two fixing devices. A locking device is arranged at the output end of each fixing device. An adapter plate is fixedly arranged between the two locking devices. An upper die is fixedly installed on the lower end surface of the adapter plate.

[0022] Refer to Figures 1-4 , a stamping die for metal keels with replaceable patterns, including a mounting base 1. A die slot 5 is provided on the upper end surface of the mounting base 1. The upper end surface of the mounting base 1 is fixedly connected with a mounting plate 2 through a plurality of fixing rods 3. A hydraulic telescopic cylinder 8 is fixedly installed on the lower end surface of the mounting plate 2. A fixing plate 4 is fixedly connected to the output shaft of the hydraulic telescopic cylinder 8, and the fixing plate 4 is sleeved on the outer walls of the plurality of fixing rods 3. A T-shaped chute 11 is provided on the lower end surface of the fixing plate 4. A driving device is provided in the T-shaped chute 11. The output ends of the driving device are symmetrically connected with two fixing devices. A locking device is provided at the output end of each fixing device. A connecting plate 9 is fixedly arranged between the two locking devices. An upper die 7 is fixedly installed on the lower end surface of the connecting plate 9.

[0023] The driving device includes a motor 6, and the motor 6 is fixedly installed on one side of the fixing plate 4 through a mounting frame. The output shaft of the motor 6 penetrates through one side of the fixing plate 4 and extends into the T-shaped chute 11 to install a double-headed threaded rod 12. The end of the double-headed threaded rod 12 far from the output shaft of the motor 6 is installed on the inner side wall of the T-shaped chute 11 through a bearing, and the output ends of the two fixing devices are respectively connected to the double-headed threaded rod 12. Driving the motor 6 can drive the double-headed threaded rod 12 to rotate in the T-shaped chute 11.

[0024] Each fixing device includes a T-shaped slider 13, and the T-shaped slider 13 is slidably clamped in the T-shaped chute 11.
