Description

Technical Field

[0001] The invention relates to the technical field of stamping dies or other mechanical manufacturing fields, and more specifically to a cylinder-driven side shaping lower die mechanism. Background Art

[0002] When arranging the process of some mold projects, some steps require both side shaping and trimming or punching. However, the conventional upper die driven wedge mold cannot arrange the trimming and punching work on the side where the drive block is located. In addition, the lower die part of the conventional upper die driven wedge mold uses a nitrogen spring as the force source. Due to the large impact force of the nitrogen spring, if there is a deviation in the calculation when selecting the nitrogen spring, it is easy to cause the lower die drive pulley to get stuck due to insufficient or excessive force when returning to its position. There will also be a phenomenon that the life of the lower die seat is greatly reduced due to excessive force and impact.

[0003] Therefore, a new structure is needed to replace the conventional upper mold drive structure, which can not only meet the requirements of process arrangement but also improve the life of the mold. Summary of the invention

[0047] Example:

[0048] According to the following Figure 1-9 A cylinder-driven side shaping lower die mechanism according to an embodiment of the present invention is described in detail.

[0049] The embodiment of the present invention discloses a cylinder-driven side shaping lower die mechanism, which is arranged on a lower die seat of a stamping die and utilizes the movement of a cylinder to realize the movement of a side shaping wedge lower die part.

[0050] like Figure 1 As shown, the cylinder-driven side shaping lower mold mechanism of the present invention includes three major parts: a driving component 100, a side shaping component 200 and an auxiliary driving component 300.

[0051] Specifically,

[0052] like Figure 2As shown, the driving assembly 100 includes a driving insert body 101, a first cylinder 102 and a second cylinder 103, and a first guide plate 104, a second guide plate 105 and a first inclined guide plate 106 are fixedly mounted on the driving insert body 101 by screws, the first guide plate 104 is slidably matched with the lower die insert mounted on the lower die seat, the second guide plate 105 is mounted on both sides of the driving insert body 101 in the axial direction and is slidably matched with the lower die seat body of the lower die seat, and the first inclined guide plate 106 is slidably matched with the fourth guide plate 202 and the second inclined guide plate 204 in the side assembly 200.

[0053] The size of the driving insert body 101 can be freely set according to the requirements; the first guide plate 104, the second guide plate 105 and the first inclined guide plate 106 are selected according to the industry standards.

[0054] The third guide plate 107, the first inclined wedge cover plate 108 and the first inclined wedge limit block 109 are fixedly installed on the lower die base body by screws. The third guide plate 107 is slidably matched with the driving insert body 101, the first inclined wedge cover plate 108 is slidably matched with the driving insert body 101, and the first inclined wedge limit block 109 is used for the movable limit of the driving insert body 101.

[0055] The third guide plate 107, the first inclined wedge cover plate 108 and the first inclined wedge limit block 109 are selected according to industry standards based on demand.

[0056] The first cylinder 102 and the second cylinder 103 are installed on the lower die base body and are distributed at both ends of the driving insert body 101 in the axial direction. The movement states of the first cylinder 102 and the second cylinder 103 are just opposite. They transmit the cylinder force to the driving insert body 101 by ejecting and retracting. That is, when the first cylinder 102 is in the ejecting state, the second cylinder 103 is in the retracting state, and when the first cylinder 102 is in the retracting state, the second cylinder 103 is in the ejecting state. The opposite movement states of the cylinders ensure that the directions of the forces acting on the driving insert body 101 are consistent.

[0057] Furthermore, a first cylinder mounting plate 110 is fixedly mounted on the lower die base body by screws, and the first cylinder 102 and the second cylinder 103 are connected to the lower die base body via the first cylinder mounting plate 110; a hollow first cylinder connecting plate 111 is fixedly mounted on the driving insert body 101 by screws, and the first cylinder 102 and the second cylinder 103 are connected to the first cylinder connecting plate 111 via the first cylinder joint 112, thereby realizing the transmission of cylinder force.

[0058] Furthermore, the small end of the first cylinder joint 112 is fixed to the first cylinder 102 and the second cylinder 103, and the large end of the first cylinder joint 112 is placed in the empty space in the first cylinder connecting plate 111, and it is ensured that the first cylinder joint 112 and the first cylinder connecting plate 111 will not be separated during the movement.

[0059] During the process of the cylinder being pushed out, the first cylinder joint 112 is pressed against the first cylinder connecting plate 111 to transmit the cylinder force to the driving insert body 101; during the process of the cylinder being retracted, the large end of the first cylinder joint 112 is hung on the first cylinder connecting plate 111 to transmit the cylinder force to the driving insert body 101.

[0060] A first anti-loosening clamping plate 113 is also fixed to the first cylinder joint 112 to prevent the first cylinder joint 112 from loosening from the first cylinder 102 and the second cylinder 103 .

[0061] The first cylinder 102 and the second cylinder 103 are selected according to industry standards based on demand.

[0062] like Figure 3-4 As shown, the side adjustment component 200 includes a side adjustment insert body 201, on which a fourth guide plate 202, a fifth guide plate 203 and a second inclined guide plate 204 are fixedly mounted by screws, the fifth guide plate 203 is slidably matched with the lower die insert mounted on the lower die base, and the fourth guide plate 202 and the second inclined guide plate 204 are slidably matched with the first inclined guide plate 106, for transmitting the driving force of the driving component 100.

[0063] The size of the side integral insert body 201 can be freely set according to the requirements, and the fourth guide plate 202, the fifth guide plate 203 and the second inclined guide plate 204 are selected according to the industry standards.

[0064] The second inclined wedge cover plate 205, the second inclined wedge limit block 206 and the side integral block limit block 207 are fixedly installed on the lower die base body by screws. The second inclined wedge cover plate 205 is slidably matched with the side integral block body 201. The second inclined wedge limit block 206 is used for the return limit of the side integral block body 201, and the side integral block limit block 207 is used for the working limit of the side integral block body 201.

[0065] The second inclined wedge cover plate 205 and the second inclined wedge limit block 206 are selected according to industry standards based on demand.

[0066] Furthermore, a concave V-guide plate 209 is fixedly installed on the side integral insert body 201 by screws, and a convex V-guide plate 210 is fixedly installed on the lower die base body by screws. The concave V-guide plate 209 and the convex V-guide plate 210 are slidably matched with each other to accurately position the reciprocating motion between the side integral assembly 200 and the lower die insert.

[0067] The above-mentioned concave V guide plate 209 and convex V guide plate 210 adopt industry standards according to needs.

[0068] like Figure 5 As shown, the auxiliary drive assembly 300 includes a third cylinder 301 , which is cooperatively connected with the side integral insert body 201 to provide auxiliary power for the side integral assembly 200 .

[0069] Furthermore, a second cylinder connecting plate 208 is fixedly mounted on the side integral insert body 201 by screws, and one end of the second cylinder connecting plate 208 away from the side integral insert body 201 is U-shaped, and the third cylinder 301 is matched and connected with the U-shaped end of the second cylinder connecting plate 208 through the second cylinder joint 302 to achieve the transmission of the cylinder force. A second cylinder mounting plate 303 is fixedly mounted on the lower die base body by screws, and the third cylinder 301 is connected to the lower die base body through the second cylinder mounting plate 303.

[0070] A second anti-loosening clamping plate 304 is also fixed on the second cylinder joint 302 to prevent the second cylinder joint 302 from loosening from the third cylinder 301 .

[0071] The third cylinder 301 is selected according to industry standards as required.

[0072] The first cylinder 102, the second cylinder 103 and the third cylinder 301 are all driven to move by the air source of the machine tool.

[0073] It should be noted that the ejection action of the third cylinder 301 should be earlier than the ejection action of the first cylinder 102 and the retraction action of the second cylinder 103, and the retraction action of the third cylinder 301 should be later than the retraction action of the first cylinder 102 and the ejection action of the second cylinder 103, so as to ensure that the resistance between the driving component 100 and the lower mold side entire component 200 is minimal when they move relative to each other.

[0074] In order to further optimize the above technical solution, if the mechanism of the present invention is used in an automated mold, the sensing surface should be placed on the driving insert body 101 and the side integral insert body 201 respectively.

[0075] like Figure 6-7 As shown, the cylinder-driven side shaping lower die mechanism of the present invention has two static states: working state and return state. In the working state, the first cylinder 102 and the third cylinder 301 are pushed out, and the second cylinder 103 is retracted; in the return state, the first cylinder 102 and the third cylinder 301 are retracted, and the second cylinder 103 is pushed out.

[0076] The first cylinder 102 and the second cylinder 103 in the driving assembly 100 serve as the main power sources for the movement process of the entire mechanism; the second cylinder joint 302 of the auxiliary driving assembly 300 cooperates with the second cylinder connecting plate 208 of the side adjustment assembly 200, so that the auxiliary driving assembly 300 can provide auxiliary power for the movement of the side adjustment assembly 200; the entire mechanism is switched between the working state and the return state through the ejection and retraction of the cylinder.

[0077] like Figure 6-9 As shown, the specific working process of the cylinder-driven side shaping lower die mechanism of the present invention is as follows:

[0078] (1) After the mold is installed on the machine tool, the upper mold parts move up to the highest point along with the slide block on the machine tool, and the mold stamping preparation is completed. At this time, the mechanism is in the return state: the first cylinder 102 in the drive assembly 100 and the third cylinder 301 in the auxiliary drive assembly 300 are in the retracted state, and the second cylinder 103 in the drive assembly 100 is in the ejection state.

[0079] (2) Place the pre-stamping process parts into the lower die and position them based on the die surface, locating pins and locating plates.

[0080] (3) Computer automatic control or manual control causes the first cylinder 102 in the driving assembly 100 and the third cylinder 301 in the auxiliary driving assembly 300 to move to the ejection state, and the second cylinder 103 in the driving assembly 100 to move to the retracted state; at this time, the driving insert body 101 moves in the direction of the second cylinder 103 under the joint action of the first cylinder 102 and the second cylinder 103, and the side integral insert body 201 moves to the maximum position along the set direction under the joint action of the driving assembly 100 and the third cylinder 301, and the first inclined guide plate 106 of the driving assembly 100 and the second inclined guide plate 204 of the side integral assembly 200 are in contact with each other, and the entire mechanism is in a working state.

[0081] (4) While the various components of the mechanism of the present invention are moving, the machine tool slide block is moved downward by automatic computer control or manual control, and at the same time, it is ensured that the movement of the various components of the mechanism of the present invention is completed before the various components of the upper mold come into contact with the various components of the lower mold.

[0082] (5) The upper die part of the mold moves downward along with the machine tool slider. After the presser and the lower die are fitted to the bottom dead center, the other parts of the upper die continue to move downward along with the machine tool slider.

[0083] (6) As the other parts of the upper die continue to move downward along with the machine tool slide, the upper die wedge component contacts the lower die guide plate, the upper die wedge moves along the side shaping direction, the other parts of the upper die continue to move downward, the upper die slide moves to the bottom dead center, and the side shaping is completed.

[0084] (7) The machine tool slide moves upward, and the upper die moves upward along with the slide.

[0085] (8) When the pressing device is separated from the lower die by a certain distance, the first cylinder 102 in the driving assembly 100 is automatically controlled by the computer or manually controlled by the machine tool air source to move to the retracted state, and the second cylinder 103 in the driving assembly 100 is moved to the ejected state, and then the third cylinder 301 in the auxiliary driving assembly 300 is controlled to move to the retracted state; the side integral insert body 201 is moved to the return state, and the stamping process parts are in a lifted and unobstructed state. At this time, the entire mechanism returns to the return state.

[0086] (9) The lower die support device of the mold lifts up the stamping process workpiece, and then the workpiece is taken out by the robot arm or the operator. At this point, one working cycle of the mold is completed.

[0087] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
