Description

Technical Field

[0001] The invention relates to the technical field of stamping dies, and more specifically to a lateral distance adjustable positioning plate for a stamping die. Background Art

[0002] With the rapid development of the automobile industry, energy conservation and emission reduction is also an inevitable trend. Many steel parts of automobile components will gradually be replaced by aluminum parts. Compared with steel parts, aluminum parts have the advantages of high strength and light weight, but they also have the disadvantage of large forming springback. Usually, the forming springback of aluminum parts is several times that of steel parts, which brings certain challenges to the forming positioning of aluminum sheet parts. In the actual debugging and production process, due to the large springback of aluminum sheet parts, the positioning plate is often insufficient in the horizontal direction, which causes the secondary purchase of the positioning plate. There are also too many considerations of the springback factor, which leads to excessive hollowing and avoidance of the stamping die and the enlargement of the installation surface in the early stage, resulting in poor mold strength and reduced overall aesthetics. Therefore, it is urgent to solve the problem of adjusting the positioning amount of the existing positioning plate. Summary of the invention

Specifically in this embodiment: the connecting block 03 is an inverted L-shaped structure composed of a vertical section and a horizontal section, a reinforcing rib 031 is provided at the connection between the vertical section and the horizontal section, and the above-mentioned lateral slide groove 032 is located on the horizontal section. It should be noted that: the present invention makes the position of the positioning block 02 in the lateral direction adjustable by slidably providing the positioning amount adjustment mechanism 04 in the lateral slide groove 032, thereby realizing the adjustable lateral positioning distance of the positioning plate, effectively solving the problems of secondary procurement of the positioning plate and more mold avoidance hollowing and poor strength caused by insufficient positioning of the positioning plate due to the large rebound amount of the aluminum plate, thereby successfully completing the forming positioning of the aluminum plate.

[0033] The positioning amount adjustment mechanism 04 includes a slider 041 and a positioning drive assembly 042 that can drive the slider 041 to slide in the transverse slide groove 032, and the positioning block 02 is connected to the end of the slider 041. It should be explained here that the positioning block 02 is connected to the end of the slider 041, that is, the end of the slider 041 extending out of the transverse slide groove 032 is connected to the positioning block 02. It should be noted that the present invention drives the slider 041 to slide in the transverse slide groove 032 through the positioning drive assembly 042, thereby driving the positioning block 02 to move in the transverse direction. When the positioning block 02 moves to the required position, the driving slider 041 is stopped, so that the position of the positioning block 02 in the transverse direction is adjustable, thereby realizing the adjustable transverse positioning distance of the positioning plate.

[0034] The positioning drive assembly 042 includes two control parts, which are respectively located on both sides of the slider 041, and a transmission part is arranged between the two control parts to connect the two control parts and can drive the slider 041 to slide under the action of the two control parts. The control part includes a first control block 0421 and a second control block 0422 which are arranged relatively and can move toward each other. A serrated clamping head 0426 is arranged on both sides of the first control block 0421 and the second control block 0422 which are opposite to each other. A serrated clamping groove 034 matching the serrated clamping head 0426 is arranged on the above-mentioned connecting block 03 along the sliding direction of the slider 041. The above-mentioned control part is fixed on the connecting block 03 by the mutually matching serrated clamping head 0426 and the serrated clamping groove 034. Specifically in this embodiment: the side surface of the slider 041 contacts the side surface of the serrated clamping groove 034. It should be noted that: first, the first control block 0421 and the second control block 0422 on the two control parts move toward each other, so that the serrated clamping heads 0426 on the two control parts are separated from the serrated grooves 034 on the connecting block 03, and then the two control parts are separated from the connecting block 03, and then the two control parts are synchronously moved to drive the slider 041 on the transmission part to slide, so that the positioning block 02 connected to the slider 041 can be moved to the required position as needed. When the positioning block 02 moves to the required position, the first control block 0421 and the second control block 0422 on the two control parts move away from each other, so that the serrated clamping heads 0426 on the two control parts are engaged with the serrated grooves 034 on the connecting block 03, and then the two control parts are engaged and fixed on the connecting block 03, so that the slider 041 cannot continue to slide, thereby realizing the adjustable lateral positioning distance of the positioning plate. It should be further explained that: the present invention can guide the slider 041 through the structural design that the side surface of the slider 041 contacts the side surface of the sawtooth-shaped slot 034 .

[0035] A thumb accommodating hole 04221 is provided on the second control block 0422, and two blind holes 04223 are provided on a side of the second control block 0422 facing the first control block 0421, a spring 04224 and a guide block 04213 in contact with the upper end of the spring 04224 are placed in each blind hole 04223, and a connecting plate 0423 that blocks the guide block 04213 in the blind hole 04223 is detachably installed on the surface, and the first control block 0421 includes a first control block body, and the first control block body is a U-shaped structure, and both side walls of the U-shaped structure extend outward to form a manual pressing lug 04211, and the two side walls of the U-shaped structure pass through the two through holes on the above-mentioned connecting plate 0423 and are detachably connected to the corresponding guide blocks 04213 respectively. Specifically in this embodiment: the line connecting the two manual pressing lugs 04211 is perpendicular to the central axis of the thumb receiving hole 04221, and the center line connecting the two manual pressing lugs 04211 and the thumb receiving hole 04221 is an acute triangle. It should be noted that the distribution arrangement of the two manual pressing lugs 04211 and the thumb receiving hole 04221 in the present invention can make the operation process more convenient. It should be further noted that the specific installation process of the control unit in the present invention is to firstly pass the two side walls of the U-shaped structure through the two through holes on the connecting plate 0423 and then respectively connect them with the corresponding guide blocks 04213 with bolts, and then put the two guide blocks 04213 into the two blind holes 04223, and make the lower end surface of the guide block 04213 contact the spring 04224, and finally install the connecting plate 0423 on the second control block 0422 by bolts; the disassembly process is opposite to the installation process.

[0036] The transmission part includes two round rods 0424, wherein the two ends of one round rod 0424 pass through the first round through holes 04212 on the two first control blocks 0421 and are respectively threadedly connected to nuts 0425, and the two ends of the other round rod 0424 pass through the second round through holes 04222 on the two second control blocks 0422 and are respectively threadedly connected to nuts 0425, and the above-mentioned slider 041 is provided with a track hole for the two round rods 0424 to pass through and slide in. Specifically in this embodiment: the track hole is a long strip waist-shaped hole 0411, and the above-mentioned two round rods 0424 both pass through the long strip waist-shaped hole 0411 and can slide in the long strip waist-shaped hole 0411 along the length direction of the long strip waist-shaped hole 0411, and the two round rods 0424 both contact the two planes on the long strip waist-shaped hole 0411. It should be noted that: in the present invention, the two round rods 0424 both pass through the long waist-shaped hole 0411 and can slide in the long waist-shaped hole 0411 along the length direction of the long waist-shaped hole 0411, and the two round rods 0424 are in contact with two planes on the long waist-shaped hole 0411. This structural design can, on the one hand, play a guiding role without affecting the relative movement of the first control block 0421 and the second control block 0422, and on the other hand, it can also drive the slider 041 to slide.

[0037] The specific operation process of the positioning amount adjustment mechanism 04 in the present invention is as follows: first, the thumb is placed in the thumb receiving hole 04221, and the other two fingers are placed on the manual pressing lug 04211, and the first control block 0421 and the second control block 0422 on one of the control parts are manually driven to move toward each other to compress the spring 04224, so that the serrated clamping head 0426 on the control part is separated from the serrated clamping groove 034 on the connecting block 03, and the other control part is operated in the same manner according to the above process, so that both control parts are separated from the connecting block 03, and then the two control parts are manually driven to move synchronously along the sliding direction of the slider 041, so that The slider 041 on the transmission part moves with the two control parts until the positioning block 02 moves to the required position. When the positioning block 02 moves to the required position, no force is manually applied to the first control block 0421 and the second control block 0422 on the two control parts. Under the restoring force of the spring 04224, the first control block 0421 and the second control block 0422 on the two control parts are restored to their initial states, and the two control parts are clamped and fixed on the connecting block 03 through the matching serrated clamping head 0426 and the serrated clamping groove 034, so that the slider 041 cannot continue to slide, thereby realizing the adjustable lateral positioning distance of the positioning plate.
