Description

Technical Field

[0001] This invention relates to the field of stamping dies, specifically to an automatic composite die for processing industrial computer chassis. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] The front panel of an industrial computer chassis is the panel directly in front of a desktop computer chassis. It is an important component of the chassis. By removing the panel, the internal components can be cleaned and replaced.

[0004] When processing the front panel of a computer chassis, it is mostly stamped using molds. Multiple ventilation holes need to be made on the panel for air cooling of the chassis's interior. The two ends of the panel need to be bent for installation on the chassis. However, bending the two sides of the panel and making the ventilation holes on the surface require two sets of molds to operate in separate steps, which greatly reduces the processing efficiency of the panel and increases the processing time of the product. In addition, adding two sets of molds will directly increase the factory's production costs. Summary of the Invention

[0008] An upper seat is installed inside the stationary mold base, and a downward pressure slope is opened inside the upper seat. The surface of the downward pressure slope covers the horizontal drive seat, and the end of the horizontal drive seat is fixedly connected to the drive rod. The end of the drive rod away from the horizontal drive seat is screwed to the drive frame. The surface of the upper seat is welded to the transmission plate, and multiple sets of piercing pins are evenly installed on the surface of the transmission plate. A reset spring is installed on the drive rod, and a pressure plate is installed on the surface of the drive rod located on the outside of the stationary mold base.

[0009] A one-way drive assembly is installed on the left side of the moving mold base. The one-way drive assembly is driven by a guide seat. The one-way drive assembly consists of a transmission seat, a drive column, a rigid column, a one-way transmission component, an upper pull seat, a drive groove, a drive frame, a limit seat, and a limit column. The end of the transmission seat is fixedly connected to the guide seat, and the bottom of the transmission seat is screwed to the drive column.

The bottom of the upper pull seat is welded to the limit column.

[0010] Furthermore, the stamping die and the stationary die base are arranged opposite to each other, and the formed part covered by the surface of the stationary die base is formed by secondary bending through the forming groove, bending plate, stamping base, forming base, and die cavity. At the same time, the surface of the formed part is perforated by multiple sets of piercing posts. The cross-section of the stationary die base is U-shaped, and a support base is fixedly installed on the inner wall of the stationary die base. Support platforms are movably installed on both sides of the inside of the die cavity, and the bottom of the support platform is opened. At the same time, a guide channel is opened inside the stationary die base, and the size of the support platform and the guide channel are adapted to each other. The support platform is slidably arranged inside the guide channel, and the support platform and the bottom of the guide channel are elastically connected by a compression spring. The top surface of the support platform is flush with the top surface of the forming base.

[0011] Furthermore, a forming groove is formed on the outer side of the stamping seat, and a bending plate is fixedly installed on the outer side of the forming groove. At the same time, the dimensions of the stamping seat and the mold cavity are matched, and the bending plate moves downward to cover the outer side of the forming seat.

[0012] Furthermore, the forming groove, the stamping seat, and the mold cavity are combined together to form a primary bending forming assembly of the formed part, and the bending plate and the forming seat are combined together to form a secondary bending forming assembly of the formed part. The cross-sections of the stamping seat and the mold cavity are both set as isosceles trapezoids.

[0013] Furthermore, fifty-six sets of receiving holes are evenly installed at the bottom of the stamping seat, and fifty-six sets of piercing posts are evenly installed on the surface of the transmission plate. At the same time, the piercing posts and receiving holes are arranged opposite to each other, and the size of the receiving holes is larger than the size of the piercing posts.

[0014] Furthermore, the downward pressure slope inside the upper seat is adapted to the size of the transverse drive seat, and the transverse drive seat covers the surface of the downward pressure slope through the lower drive surface on the lower right side. The transverse drive seat moves from left to right, driving the upper seat, transmission plate and puncture column to move downward.

[0015] Furthermore, guide blocks are installed on both sides of the upper seat, and two sets of guide posts are inserted inside the guide blocks. Springs are installed on both sets of guide posts, and the guide posts are fixed inside the stationary mold seat.

[0016] Furthermore, an "L"-shaped limiting seat is screwed onto the left side of the base, and a limiting post is inserted into the limiting hole inside the limiting seat. At the same time, an upper pressing slope is opened at the end of the upper pull seat on the upper side of the limiting post, and the upper pull seat covers the force-bearing slope opened on the inner wall of the drive groove through the upper pressing slope at the end.

[0017] Furthermore, the unidirectional transmission component consists of a reversing groove, a transmission cylinder, a slider, a first locking arm, a latch, a locking column, and a second locking arm. The bottom of the rigid column is fixedly disposed with respect to the surface of the slider, while the slider is slidably disposed inside the transmission cylinder. The bottom of the transmission cylinder is welded and fixed to the upper pull seat. The first locking arm and the second locking arm are respectively movably mounted on the slider via pins, and the first locking arm and the second locking arm are elastically connected by a damping spring.

[0018] Furthermore, the bottom of both the first and second locking arms is fixedly connected to an "L"-shaped latch, and the bottom of the latch is arc-shaped.

Two sets of deflection grooves are opened on the top plate of the transmission cylinder, and the two sets of deflection grooves are respectively arranged opposite to the tail ends of the first and second locking arms. The cross-section of the deflection grooves is a right trapezoid.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] When the mold is closed, the drive seat moves downward, causing the stamping seat to act on the lower forming part, and the stamping seat performs the first forming of the forming part; the bending plate moves downward to perform the second forming of the lower forming part, and at the same time the lower forming part covers the 56 sets of piercing pillars, piercing to form 56 sets of heat dissipation holes, and performing the third forming; the three processing of the forming part can be performed in one step using this composite mold, without the need to use other molds for re-forming work, which greatly reduces the mold opening and forming cost of the panel, and saves labor costs.

[0031] Detailed implementation method one: Please refer to Figure 1-9The present invention provides a technical solution: an automatic composite mold for processing industrial computer chassis, including a moving mold base 1 and a stationary mold base 11. A hydraulic cylinder is screwed onto the moving mold base 1, and the piston rod of the hydraulic cylinder is screwed onto the drive base 2. The bottom wall of the stationary mold base 11 is fixed to the base 4, and support columns are installed on both sides of the surface of the base 4. At the same time, guide seats 3 are fixedly installed at both ends of the drive base 2, and support columns are inserted into the guide holes opened inside the guide seats 3. The bottom wall of the drive base 2 is fixedly connected to the stamping die 5, and the bottom of the stamping die 5 is fixedly connected to the stamping base 8. The stationary mold base 11 is installed on the lower side of the stamping base 8, and the surface of the stationary mold base 11 is covered with a molded part 13.

[0032] An upper seat 114 is movably mounted inside the stationary mold base 11, and a downward pressure slope 113 is formed inside the upper seat 114. At the same time, the surface of the downward pressure slope 113 covers the horizontal drive seat 118, and the end of the horizontal drive seat 118 is fixedly connected to the drive rod 119. The end of the drive rod 119 away from the horizontal drive seat 118 is screwed and fixed to the drive frame 127. The surface of the upper seat 114 is welded and fixed to the transmission plate 111, and multiple sets of piercing posts 1111 are evenly installed on the surface of the transmission plate 111. A reset spring is installed on the drive rod 119, and a pressure plate is installed on the surface of the drive rod 119 located on the outside of the stationary mold base 11.

[0033] A one-way drive assembly 12 is installed on the left side of the moving mold base 1, and the one-way drive assembly 12 is driven by the guide seat 3. The one-way drive assembly 12 consists of a transmission seat 121, a drive column 122, a rigid column 123, a one-way transmission component 124, an upper pull seat 125, a drive groove 126, a drive frame 127, a limit seat 128, and a limit column 129. The end of the transmission seat 121 is fixedly connected to the guide seat 3, and the bottom of the transmission seat 121 is screwed to the drive column 122. The bottom of the drive column 122 is welded to the rigid column 123. The bottom of the rigid column 123 is inserted into the interior of the one-way transmission component 124, and the bottom of the one-way transmission component 124 is welded to the upper pull seat 125. At the same time, the bottom of the upper pull seat 125 is welded to the limit column 129.

[0034] Working principle: During use, when the mold is closed, the drive seat 2 moves downward, causing the stamping seat 8 to act on the lower forming part 13, and the stamping seat 8 performs a first forming on the forming part 13; the bending plate 7 moves downward to perform a second forming on the lower forming part 13, and at the same time the lower forming part 13 covers the 56 sets of piercing pillars 1111, piercing to form 56 sets of heat dissipation holes, performing a third forming; the three processing of the forming part 13 can be performed in one step using this composite mold, without the need to use other molds for re-forming work, which greatly reduces the mold opening and forming cost of the panel, and saves labor costs.

[0035] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One. The stamping die 5 and the stationary die base 11 are arranged opposite to each other, and the forming part 13 covered on the surface of the stationary die base 11 is formed by secondary bending through the forming groove 6, bending plate 7, stamping seat 8, forming seat 9, and die cavity 10. At the same time, the surface of the forming part 13 is perforated through multiple sets of piercing columns 1111. The cross section of the stationary die base 11 is arranged in a "U" shape, and the support seat 112 is fixedly installed on the inner wall of the stationary die base 11. The support platform 101 is movably installed on both sides of the interior of the die cavity 10, and the bottom of the support platform 101 is opened with an opening 102. At the same time, the guide channel 103 is opened inside the stationary die base 11, and the dimensions of the support platform 101 and the guide channel 103 are adapted to each other. The support platform 101 is slidably arranged inside the guide channel 103, and the bottom of the support platform 101 and the guide channel 103 are elastically connected by a compression spring 104. The top surface of the support platform 101 is flush with the top surface of the forming seat 9.

[0036] like Figure 9 As shown: During mold closing, the molded part 13 covers the upper surface of the molding base 9 and is supported and fixed by the support platforms 101 on both sides inside the mold cavity 10.

[0037] When the molded part 13 is formed under force, the two sets of support platforms 101 support and fix the bottom sides of the molded part 13 respectively. The molded part 13 is pressed by force, which compresses the lower pressure spring 104. When the molded part 13 is formed and the mold is opened, the compressed lower pressure spring 104 rebounds after the bending and hole opening operations are completed, causing the molded part 13 to be demolded.

[0038] like Figure 1 and Figure 4-5 As shown: When the stamping die 5 and the stationary die base 11 are closed, the stamping base 8 presses on the surface of the forming part 13 to form it in one step.

[0039] The bending plate 7 moves downward, bending both ends of the formed part 13 to form a secondary bend; simultaneously, as the formed part 13 is pressed down, 56 sets of heat dissipation holes are formed by 56 sets of piercing pins 1111 through piercing and punching. The shape formed by the composite mold of the formed part 13 is as follows: Figure 8 As shown.

[0040] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 1. A forming groove 6 is opened on the outer side of the stamping seat 8, and a bending plate 7 is fixedly installed on the outer side of the forming groove 6. At the same time, the dimensions of the stamping seat 8 and the mold cavity 10 are compatible, and the bending plate 7 moves downward to cover the outer side of the forming seat 9.

[0041] like Figure 1 and Figure 4-5As shown: the bending plate 7 moves downward to cover the outside of the forming seat 9. The space between the bending plate 7 and the forming seat 9 forms a bending mold cavity for the two wings of the forming part 13. At the same time, it moves downward through the forming groove 6 to cover the forming seat 9, so that the two wings of the forming part 13 form a bending part with a right-angle adjustable cross section.

[0042] Specific Implementation Method 4: This implementation method is a further limitation of Specific Implementation Method 3. The forming groove 6, the stamping seat 8 and the mold cavity 10 are combined together to form a primary bending forming component of the forming part 13, and the bending plate 7 and the forming seat 9 are combined together to form a secondary bending forming component of the forming part 13. The cross-sections of the stamping seat 8 and the mold cavity 10 are both set as isosceles trapezoids.

[0043] like Figure 1-6 As shown: The forming groove 6, the stamping seat 8 and the mold cavity 10 are combined together to form the one-time bending forming assembly of the forming part 13;

[0044] The bending plate 7 and the forming seat 9 are combined to form the secondary bending forming component of the forming part 13;

[0045] The forming component 13 can be bent into two shapes simultaneously using a single bending forming component and a double bending forming component.

[0046] Specific Implementation Method 5: This implementation method is a further limitation of Specific Implementation Method 1. Fifty-six sets of receiving holes 1112 are evenly installed on the bottom of the stamping seat 8, and fifty-six sets of piercing posts 1111 are evenly installed on the surface of the transmission plate 111. At the same time, the piercing posts 1111 and the receiving holes 1112 are arranged opposite to each other, and the size of the receiving holes 1112 is larger than the size of the piercing posts 1111. The distance between two adjacent sets of piercing posts 1111 and receiving holes 1112 is the same.

[0047] like Figure 1 and Figure 7-8 As shown: 56 sets of receiving holes 1112 and piercing posts 1111 are provided. When the stamping seat 8 moves downward, the surface of the formed part 13 is subjected to force. The 56 sets of piercing posts 1111 pierce and form 56 sets of heat dissipation holes. The ends of the piercing posts 1111 are accommodated inside the receiving holes 1112 to avoid motion interference between the piercing posts 1111 and the stamping seat 8.

[0048] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Method One. The downward pressing slope 113 opened inside the upper seat 114 is adapted to the size of the horizontal drive seat 118, and the horizontal drive seat 118 covers the surface of the downward pressing slope 113 through the lower drive surface opened on the lower right side. The horizontal drive seat 118 moves from left to right, driving the upper seat 114, the transmission plate 111 and the piercing column 1111 to move downward.

[0049] like Figure 1-6As shown: During mold closing: the 56 groups of piercing pins 1111 are driven by the one-way drive assembly 12; when the drive seat 2 moves downward, the one-way drive assembly 12 does not drive the piercing pins 1111.

[0050] When the mold is opened: When the drive seat 2 moves upward, the first locking arm 1244 and the second locking arm 1247 lock the locking post 1246; this can drive the pull seat 125 to move downward, and drive the drive frame 127, drive rod 119 and limit seat 128 to move from left to right. The limit seat 128 moves to the right and drives the upper seat 114 and transmission plate 111 to move downward through the downward pressing slope 113, so that the 56 sets of piercing posts 1111 are separated from the molded part 13, which facilitates the demolding of the molded part 13.

[0051] Specific Implementation Method Seven: This implementation method is a further limitation of Specific Implementation Method One. Guide blocks 115 are installed on both sides of the upper seat 114, and two sets of guide posts 116 are inserted into the inside of the guide blocks 115. At the same time, springs 117 are installed on both sets of guide posts 116, and the guide posts 116 are fixedly connected to the inside of the stationary mold seat 11.

[0052] like Figure 1 and Figure 7 As shown: When the upper seat 114 is raised or lowered, guide posts 116 are inserted into the guide blocks 115 on both sides, which can limit and guide the vertical movement of the upper seat 114. When the force acting on the upper seat 114 disappears, the spring 117 resets, so that the upper seat 114 returns to the initial position.

[0053] Specific Implementation Method Eight: This implementation method is a further limitation of Specific Implementation Method One. An "L"-shaped limiting seat 128 is screwed onto the left side of the base 4, and a limiting post 129 is inserted into the limiting hole opened inside the limiting seat 128. At the same time, an upper pressing slope is opened at the end of the upper pull seat 125 on the upper side of the limiting post 129, and the upper pull seat 125 covers the force-bearing slope opened on the inner wall of the drive groove 126 through the upper pressing slope at the end.

[0054] like Figure 1-5As shown: During mold closing, the drive seat 2 moves downward. The guide seat 3 at the end of the drive seat 2 drives the transmission seat 121, drive column 122, and rigid column 123 to move downward. When the rigid column 123 moves downward, it drives the slider 1243 to move downward, causing the first locking arm 1244 and the second locking arm 1247 to move downward. The arc-shaped surfaces at the bottom of the first locking arm 1244 and the second locking arm 1247 act on both sides of the top of the locking column 1246. Under the action of the lever principle, the first locking arm 1244 and the second locking arm 1247 lock the upper end of the locking column 1246 through two sets of latches 1245. When the mold opens, the upper pull seat 125 can be driven upward by the rigid column 123. Finally, the 56 sets of piercing columns 1111 move downward and separate from the molded part 13, which facilitates the demolding of the molded part 13.

[0055] Specific Implementation Method Nine: This implementation method is a further limitation of Specific Implementation Method One. The one-way transmission component 124 is composed of a reversing groove 1241, a transmission cylinder 1242, a slider 1243, a first locking arm 1244, a latch 1245, a locking post 1246, and a second locking arm 1247. The bottom of the rigid post 123 is fixedly disposed with respect to the surface of the slider 1243. At the same time, the slider 1243 is slidably disposed inside the transmission cylinder 1242. The bottom of the transmission cylinder 1242 is welded and fixed to the upper pull seat 125. The first locking arm 1244 and the second locking arm 1247 are respectively movably mounted on the slider 1243 through pins. The first locking arm 1244 and the second locking arm 1247 are elastically connected by a damping spring.

[0056] like Figure 2-3 As shown: When the first locking arm 1244 and the second locking arm 1247 drive the locking pin 1246 to move upward, when the upper ends of the first locking arm 1244 and the second locking arm 1247 are inserted into the direction-changing groove 1241, the bottom of the first locking arm 1244 and the second locking arm 1247 expands outward under the action of the lever principle, the locking pin 1246 is released, and the unidirectional drive assembly 12 returns to its initial state, forming a complete demolding cycle.

[0057] Specific Implementation Method 10: This implementation method is a further limitation of Specific Implementation Method 9. The bottom of the first locking arm 1244 and the second locking arm 1247 are both fixedly connected to the "L"-shaped latch 1245, and the bottom of the latch 1245 is arc-shaped. At the same time, the first locking arm 1244 and the second locking arm 1247 move downward and are locked onto the "T"-shaped locking post 1246 through the latch 1245. Two sets of deflection grooves 1241 are opened on the top plate of the transmission cylinder 1242, and the two sets of deflection grooves 1241 are respectively arranged opposite to the tail ends of the first locking arm 1244 and the second locking arm 1247. The cross section of the deflection groove 1241 is a right-angled trapezoid.

[0058] When the mold is closed, the stamping die 5 moves downward and the bottom of the stamping seat 8 presses the forming part 13 downward. At this time, in order to ensure the stability of the piercing column 1111 during piercing and prevent it from moving, a metal pad is inserted into the bottom of the upper seat 114 to support the upper seat 114. When the heat dissipation hole is pierced, the metal pad is removed.
