A type of edge pressing forming component structure

Abstract

The present invention discloses a pressure edge forming component structure, which comprises an upper punch and a lower punch, wherein the upper punch is connected with a rod punch, and the lower punch is arranged on an inclined wedge component, which is arranged in a concave template, wherein one end of the inclined wedge component corresponds to the position of the rod punch, and one end of the lower punch is connected to the other end of the inclined wedge component. The rod punch connected to the upper punch can move simultaneously with the upper punch, and since the position of one end of the inclined wedge component corresponds to the position of the rod punch, when the rod punch moves downward, it can contact one end of the inclined wedge component on the concave template, and drive the inclined wedge component to move, so that the lower punch at the other end of the inclined wedge component moves upward, thereby extending out of the concave template and acting on the product simultaneously with the upper punch to perform pressure edge processing, thereby ensuring the flatness of the product plane and making the pressure edge heights of the upper and lower surfaces of the product the same.

Description

Technical Field

[0001] The invention relates to the technical field of stamping die parts, in particular to a press edge forming component structure. Background Art

[0002] Stamping is a processing method with high production efficiency and low material consumption. The stamping process is suitable for the production of large batches of parts and products, which is easy to realize mechanization and automation and has high production efficiency. At the same time, stamping production can not only strive to achieve less waste or no waste production, but also make full use of leftovers in some cases. In the stamping process, the product is often pressed according to the needs.

[0003] In the existing press edge structure of the stamping die, in order to avoid the phenomenon that multiple bent parts are easily stuck on the die after the press edge work is completed, the lower punch is generally set higher than the surface of the die, and the upper punch presses down and cooperates with the lower punch to extrude both sides of the product, thereby achieving the press edge effect. However, in such a structure, since the lower punch is higher than the surface of the die, when the die is closed during the molding process of the product, the lower surface is first subjected to the upward force of the lower punch. At this time, the upper punch has not started to press the product. Therefore, the upper and lower punches cannot work at the same time, resulting in uneven molding of the product and possible bending. Moreover, since the upper punch and the lower punch cannot act on the product at the same time, it will also make it difficult to achieve consistency in the press edge heights of the upper and lower sides of the product. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an upward forming component structure which is not easy to make the product stuck on the mold and can make the lower punch and the upper punch act on the product at the same time.

[0005] The technical solution adopted by the present invention is: a edge pressing forming component structure, which includes an upper punch and a lower punch, the upper punch is connected to a hitting rod punch, the lower punch is arranged on an inclined wedge component, the inclined wedge component is arranged in a concave template, one end of the inclined wedge component corresponds to the position of the hitting rod punch, and one end of the lower punch is connected to the other end of the inclined wedge component.

[0006] After adopting the above structure, a edge pressing forming component structure of the present invention has the following advantages compared with the prior art: the hitting rod punch connected to the upper punch can move simultaneously with the upper punch. Since the position of one end of the inclined wedge component corresponds to the position of the hitting rod punch, when the hitting rod punch moves downward, it can contact one end of the inclined wedge component on the concave template, and drive the inclined wedge component to move, so that the lower punch at the other end of the inclined wedge component moves upward, thereby extending out of the concave template and acting on the product simultaneously with the upper punch to perform edge pressing processing, thereby ensuring the flatness of the product plane and making the edge pressing heights on the upper and lower surfaces of the product the same.

[0007] Preferably, the wedge assembly includes a first slider, a second slider, and a third slider, one end of the first slider corresponds to the position of the punch, the other end of the first slider is a first inclined surface, the cross section of the second slider is a trapezoid, the second inclined surface arranged at one end of the second slider is slidably connected to the first inclined surface, the third inclined surface arranged at the other end of the second slider is slidably connected to the fourth inclined surface arranged at one end of the third slider, and the lower punch is connected to the upper end of the third slider. The first slider is used to contact the punch and move downward following the movement of the punch. During the movement of the first slider, the vertical movement of the first slider is converted into the horizontal movement of the second slider through the cooperation between the first inclined surface and the second inclined surface on the second slider. When the second slider moves, the horizontal movement of the second slider is converted into the vertical movement of the third slider through the cooperation between the third inclined surface and the fourth inclined surface of the third slider, and finally drives the lower punch to move upward. In this way, the synchronization of the movement is ensured, so that the upper punch and the lower punch move toward the product at the same time and press the edge thereof.

[0008] Preferably, the first slider and the second slider are arranged at right angles to each other, and the second slider and the third slider are arranged at right angles to each other. Such an arrangement makes the motion transmission between the first slider, the second slider and the third slider stable and reliable, ensuring that after the rod punch contacts the first slider, the movement amount of the upper punch and the lower punch is equal.

[0009] Preferably, the other end of the third slider is provided with a fifth inclined surface symmetrical to the fourth inclined surface, and the first slider and the second slider are also symmetrically arranged on the fifth inclined surface, and are slidably connected to the fifth inclined surface. Such an arrangement can make both sides of the third slider be subjected to the same movement at the same time, making the movement of the third slider more stable and not tilting, so that the lower punch will not tilt due to the tilt of the third slider during the rising process, ensuring the accurate position of the edge pressing.

[0010] Preferably, a reset mechanism is connected to the lower end of the third slider, and the reset mechanism includes a pull rod bolt, a spring, a sleeve, and a pad. The sleeve passes through the concave template, one end of the sleeve contacts the third slider, and the other end of the sleeve is connected to the pad. The spring is sleeved on the outside of the sleeve, one end of the spring contacts the concave template, and the other end of the spring contacts the pad. The bolt passes through the pad and the sleeve and is connected to the third slider. When the edge pressing action is performed, the third slider moves upward under the pressure of the rod punch, pulling the pull rod bolt to move and compressing the spring; when a edge pressing action is completed, when the rod punch starts to move upward, the pull rod bolt and the third slider are driven downward by the elastic force of the spring to return to their original position; such a setting allows the edge pressing action to be repeated, ensuring the continuity of the edge pressing work.

[0011] Preferably, a lower die seat is provided at the lower end of the concave mold plate, a hole is provided on the lower die seat, and the reset mechanism is arranged in the hole of the lower die seat. The lower die seat not only serves as the basic base of the entire edge pressing molding assembly structure, but also provides a space for accommodating the reset mechanism, and can also ensure that the spring will not be displaced during operation, thereby ensuring the stability of the movement.

[0012] Preferably, a pressure plate is further provided at the upper end of the concave mold plate, one end of which extends above the first slider and contacts the upper end of the first slider. The pressure plate is used to limit the movement of the first slider when the reset mechanism performs a reset action, so as to prevent the first slider from rising too far and leaving the concave mold plate or causing a malfunction.

[0013] Preferably, a punch fixing plate is further provided at the upper end of the third slider, and the punch fixing plate is used to fix the lower punch and the third slider, so that the connection between the lower punch and the third slider is firm and reliable without tilting.

[0014] Preferably, a stopper is further provided in the concave template, and the stopper is detachably connected between the concave template and the first slider, and is slidably connected to the outer side surface of the first slider. The stopper is provided to prevent the first slider from wearing the concave template during operation, or to prevent the concave template from being damaged by the pressure generated on the concave template, so as to facilitate maintenance of the slider and the stopper. At the same time, if damage occurs, the entire concave template does not need to be replaced, and only the stopper needs to be replaced to restore normal function.

[0015] Preferably, the concave die plate is further provided with a punch guide plate, on which a through hole matching the size and shape of the lower punch is provided, and the lower punch passes through the through hole. The punch guide plate can guide the product material to allow it to pass smoothly, and on the other hand, guide the movement of the lower punch to ensure its accurate position. At the same time, the setting of the punch guide plate can also limit the third slider and the punch fixing plate to prevent them from rising too much. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] According to the instruction manual Figure 1-2 As shown, the present invention provides a pressure edge forming assembly structure, which includes an upper punch 1 and a lower punch 2. The upper punch 1 is connected to a rod punch 1.1, and the rod punch 1.1 moves with the upper punch 1. The lower punch 2 is arranged on an inclined wedge assembly 4, and the inclined wedge assembly 4 is arranged in a concave mold plate 3. The inclined wedge assembly 4 includes a first slider 4.1, a second slider 4.2, and a third slider 4.3. The first slider 4.1 is slidably connected to the second inclined surface at one end of the second slider 4.2 through a first inclined surface, and the third inclined surface at the other end of the second slider 4.2 is slidably connected to the fourth inclined surface of the third slider 4.3, wherein the position of the first slider 4.1 corresponds to the position of the rod punch 1.1, and the third slider 4.3 is connected to the lower punch 2. The first slider 4.1 and the second slider 4.2 are at right angles to each other, and the second slider 4.2 and the third slider 4.3 are at right angles to each other. The cross section of the third slider 4.3 is an equilateral trapezoid. On the other side of the third slider 4.3, a first slider 4.1 and a second slider 4.2 are symmetrically arranged along the center line of the third slider 4.3.

[0022] The upper punch 1 and the lower punch 2 can be changed in shape, quantity and position according to the needs of the product 9. In this embodiment, the upper punch 1 and the lower punch 2 are each provided with two.

[0023] A punch fixing plate 7 is also provided at the upper end of the third slide block 4.3 to fix the upper punch 1 and the third slide block 4.3, so that the lower punch 2 is stable and secure and will not tilt.

[0024] A stopper 3.1 is also provided in the concave template 3. The stopper 3.1 is provided on the side of the concave template 3 in contact with the first slider 4.1 to prevent the first slider 4.1 from wearing against the concave template 3 during operation or from damaging the concave template 3 due to pressure generated thereon. The setting of the stopper 3.1 facilitates maintenance and care. When the stopper 3.1 is damaged, the concave template 3 can be continued to be used by simply replacing the stopper 3.1 without replacing the entire concave template 3.

[0025] A reset mechanism 5 is also provided below the wedge assembly 4. The reset mechanism 5 includes a sleeve 5.1, a cushion block 5.2, a spring 5.3, and a bolt 5.4. One end of the sleeve 5.1 abuts against the bottom of the third slider 4.3, and the other end is connected to the cushion block 5.2. The spring 5.3 is sleeved outside the sleeve 5.1, one end abuts against the bottom of the concave mold plate 3, and the other end abuts against the cushion block 5.2. The bolt 5.4 passes through the cushion block 5.2 and the sleeve 5.1, and is connected to the third slider 4.3. A lower die seat 6 is also provided below the concave mold plate 3. A hole is provided on the lower die seat 6, and the reset mechanism 5 is accommodated in the hole.

[0026] A pressing plate 5.5 is also connected to the concave template 3, and one end of the pressing plate 5.5 extends to the top of the first slider 4.1. When the first slider 4.1 is in the initial position, the upper end of the pressing plate 5.5 contacts the lower end surface. In this embodiment, a groove is also provided at the position where the upper end of the first slider 4.1 contacts the pressing plate 5.5, so that the state of the first slider contacting the pressing plate in the initial position is firm and stable. At the same time, a boss or a limit block can also be provided on the rod punch 1.1. After the rod punch 1.1 moves downward a certain distance, the boss or the limit block contacts the upper end surface of the pressing plate 5.5, thereby limiting the rod punch 1.1 and preventing it from pressing down too far.

[0027] A punch guide plate 8 is also provided on the concave die plate 3. The punch guide plate 8 is arranged above the punch fixing plate 7 and is used to guide the movement of the lower punch 2 to ensure the accuracy of the edge pressing position.

[0028] According to the instruction manual Figure 1-3The working principle is that when the upper punch 1 moves downward, it drives the rod punches 1.1 on both sides to move downward together. The rod punch 1.1 contacts the upper end surface of the first slider 4.1 of the inclined wedge assembly 4 before the upper punch 1, and pushes the first slider 4.1 to move downward. During the downward movement of the first slider 4.1, the vertical movement of the first slider 4.1 is converted into the horizontal movement of the second slider 4.2 through the action between the first inclined surface and the second inclined surface of the second slider 4.2. During the movement of the second slider 4.2, the horizontal movement of the second slider 4.2 is converted into the vertical movement of the third slider 4.3 through the action between the third inclined surface and the fourth inclined surface of the third slider 4.3, so that the third slider 4.3 moves upward, thereby driving the lower punch 2 to move upward. After the lower punch 2 passes through the punch guide plate 8, it acts on the upper and lower surfaces of the product 9 simultaneously with the upper punch 1 to perform edge pressing processing on the product 9. During the upward movement of the third slider 4.3, the bolt 5.4 and the pad 5.2 are driven to move together, so that the spring 5.3 is compressed. After the edge pressing is completed, the upper punch 1 starts the reset action and moves upward. At this time, the third slider 4.3 is pulled downward by the spring 5.3 of the reset mechanism 5, and at the same time, the second slider 4.2 and the first slider 4.1 are moved to the original position. When the first slider 4.1 moves to contact with the pressure plate 5.5, the pressure plate 5.5 restricts the first slider 4.1 to stop its movement, and the upper punch 1 and the rod punch 1.1 continue to move upward until they return to their original positions. At this time, one cycle of the edge pressing action is completed.

[0029] The above is an explanation of the preferred embodiments of the present invention, but it cannot be understood as a limitation of the claims. The present invention is not limited to the above embodiments, and its specific structure is allowed to be changed. All changes made within the scope of protection of the independent claims of the present invention are within the scope of protection of the present invention.
