Description

Technical Field

[0001] The utility model relates to the technical field of punching tooling, in particular to a novel side punching tooling. Background Art

[0002] The holes on the existing front engine compartment connection brackets have multi-directional angles. Due to the limited space of the current die, traditional trimming and punching methods cannot be used. For example, adding a die will increase the tooling cost, and it will also cause varying degrees of waste in later stamping, maintenance, management, etc. Therefore, there is an urgent need for a novel punching tooling that can achieve multi-directional angle punching, and the components required by the structure are the same as those of the traditional structure, and the processing, assembly, etc. are also the same, without additional product costs, and can also ensure convenient stamping, maintenance, and management in the later stage. Summary of the Utility Model

[0003] In order to solve the above technical problems, the utility model proposes a novel side punching tooling.

[0004] The technical problems to be solved by the utility model are realized by the following technical solutions:

[0005] A novel side punching tooling includes a concave die, a blank holder located above the concave die, and an upper die base located above the blank holder. A slider is slidably installed at the bottom of the upper die base. A punch is provided at the front end of the slider. The punch is located above the blank holder. A driving block is connected to the rear side of the concave die;

[0006] The blank holder and the upper die base are connected to the machine tool. The front engine compartment connection bracket is placed on the concave die. When the machine tool drives the blank holder and the upper die base to move downward, when the slider contacts the driving block, the blank holder simultaneously presses the front engine compartment connection bracket to make it stable. The machine tool continues to drive the upper die base to move downward. The slider moves obliquely under the guidance of the driving block. The oblique movement of the slider simultaneously drives the punch to move obliquely synchronously. When the punch contacts the front engine compartment connection bracket and punches into the concave die, the punching of the hole at this angle is completed.

[0007] As a further improvement of the utility model, a guide slider is provided at the bottom of the upper die base, and the slider is installed on the guide slider.

[0008] As a further improvement of the utility model, a slider nitrogen spring is provided at the rear end of the slider, and a top block is provided at the rear side of the bottom of the upper die base.

[0009] As a further improvement of the utility model, V-shaped guide sliders are correspondingly provided on the oblique end faces of the slider and the driving block.

[0010] As a further improvement of the present utility model, the punch is inclined, and the inclination angle of the punch, the oblique sliding angle of the slider and the normal direction of the punching angle are the same.

[0011] The beneficial effects of the present utility model are:

[0012] The present utility model provides a new type of side punching tooling. Compared with the punching scheme of the traditional trimming punching method, this tooling can achieve multi-directional angle punching of products under the condition of limited die space, reduce the number of equipment and labor costs, and facilitate later stamping, maintenance and management.

[0017] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model is further described below in conjunction with the drawings and embodiments.

[0018] As Figure 1 and Figure 2 shown, a new type of side punching tooling mainly includes an upper die base 2, a guide slider 3, a slider nitrogen spring 4, an ejector block 5, a slider 6, a driving block 7, a V-shaped guide slider 8, a pressure plate 9, a punch 10, and a die 11.

[0019] The upper die base 2 and the blank holder 9 are connected to the machine tool during use; the guide slider 3 is installed at the bottom of the upper die base 2, the slider nitrogen spring 4 is installed at the rear position on the upper side of the slider 6, and the ejector block 5 is installed at the rear side of the bottom of the upper die base 2; the slider 6 is slidably installed on the guide slider 3, and the guide slider 3 provides lubrication for the horizontal movement of the slider 6 to reduce the friction during movement; the driving block 7 is connected to the rear side of the female die 11, and the V-shaped guide slider 8 is installed on the inclined end face of the driving block 7 to provide lubrication for the inclined movement of the slider 6 to reduce the friction during movement; the punch 10 is installed at the front end of the slider 6, the punch 10 is inclined, and the inclination angle of the punch 10, the inclined sliding angle of the slider 6 are normal to the punching angle.

[0020] The working principle and usage process of the present utility model are as follows:

[0021] The upper die base 2 and the blank holder 9 are connected to the machine tool. The front engine compartment connection bracket 1 is placed on the female die 11. During use, the machine tool drives the upper die base 2 and the blank holder 9 to move downward. The slider 6, the blank holder 9, the punch 10, etc. move downward simultaneously. When the V-shaped guide slider 8 on the slider 6 contacts the V-shaped guide slider 8 on the driving block 7, the blank holder 9 presses the front engine compartment connection bracket 1 to make the front engine compartment connection bracket 1 stable. Then the machine tool drives the slider 6 and the punch 10 on the upper die base 2 to continue moving downward. The Z-direction of the slider 6 is converted into an inclined movement. Since the inclination angle of the punch 10 and the inclined sliding angle of the slider 6 are normal to the punching angle, when the punch 10 contacts the front engine compartment connection bracket 1 and punches into the female die 11, the punching of this angle hole is completed. At this time, the die is closed, and the front end of the slider nitrogen spring 4 contacts the ejector block 5, making the slider nitrogen spring 4 in a compressed state to provide a power source for the return stroke.

[0022] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present utility model.
