Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping dies, and more specifically to a guide block for a deep drawing stamping die for automotive sheet metal parts. Background Technology
[0002] As the automotive industry continues to demand higher precision and production efficiency from sheet metal parts, stamping dies, as the core equipment for deep drawing of sheet metal parts, directly impact product quality and production continuity due to the stability of their guiding system. The core operation of stamping dies relies on the precise relative movement of the upper and lower dies, and the guide block, as a key component of the guiding system, must ensure the upper die smoothly approaches or moves away from the lower die throughout the entire process. Existing guide blocks mostly employ traditional sliding or rolling structures. Due to factors such as insufficient material wear resistance, easily diminished lubrication, and limited structural design adaptability, problems such as increased guide clearance and uneven movement resistance easily arise during long-term, high-frequency stamping operations, making it difficult to achieve a continuously stable guiding effect. Utility Model Content
[0003] To overcome the shortcomings of the prior art, the present invention provides a guide block for a deep drawing stamping die for automotive sheet metal parts. Its beneficial effect is that it can provide stable guidance, so that the upper die can stably approach or move away from the lower die.
[0004] A guide block for a deep drawing stamping die for automotive sheet metal parts includes a lifting block. The left and right ends of the lifting block are vertically slidably connected to two side rods. Both ends of the lifting block are provided with wheel frames, and two rollers are rotatably connected to each wheel frame. The two rollers contact the two sides of the corresponding side rods respectively.
[0005] It also includes a top beam, with its two ends connected to the upper parts of the two side bars respectively.
[0006] Both ends of the top beam are equipped with sockets, and the upper parts of the two side rods are inserted into the two sockets respectively.
[0007] Each of the sockets is fitted with a pin that passes through the upper part of the side rod to secure the side rod to the socket.
[0008] A transverse groove is provided on the top beam, and a sliding sleeve is slidably connected to the top beam in the left and right directions. The upper part of the hydraulic cylinder is fixed on the sliding sleeve, and the hydraulic cylinder passes through the transverse groove.
[0009] The translation sleeve is connected to a fastening screw via a thread, and the fastening screw presses against the top beam.
[0010] The lower end of the hydraulic cylinder is fixed with an insert block, and a fixing sleeve is fixed on the lifting block, with the insert block inserted into the fixing sleeve.
[0011] A sphere is fixed at the center of the lower side of the lifting block, and four adjusting screws are threadedly connected to the lifting block, with the four adjusting screws evenly distributed around the sphere.
[0012] The stamping die includes a lower die with a groove, a punch above the groove, a round bowl fixed to the upper die, a ball rotatably connected to the round bowl, and four adjusting screws with hemispherical lower ends, all of which rest on the upper side of the upper die.
[0013] Support legs are fixed at the four lower corners of the lower mold. Attached Figure Description

[0017] A guide block for a deep drawing stamping die for automotive sheet metal parts includes a lifting block 1. The left and right ends of the lifting block 1 are vertically slidably connected to two side rods 15. Both ends of the lifting block 1 are provided with wheel frames 14. Each wheel frame 14 is rotatably connected to two rollers 13. The two rollers 13 are in contact with the two sides of the corresponding side rods 15.
[0018] like Figure 1-3 As shown; The lifting block 1 contacts the two sides of the side rod 15 through the rollers 13 on the two end wheel frames 14, which transforms the vertical sliding into roller rolling. This reduces the resistance to movement and, with the bidirectional limiting of the rollers on both sides, prevents the lifting block 1 from deviating or shaking during the sliding process. This ensures that the lifting block 1 moves vertically and smoothly along the side rod 15, laying the foundation for the stable lifting of the upper mold.
[0019] It also includes a top beam 12, the two ends of which are connected to the upper parts of the two side bars 15 respectively.
[0020] like Figure 1-3 As shown; The top beam 12 connects the upper part of the two side rods 15 to form a stable portal frame structure, which restricts the relative position of the two side rods 15, prevents the side rods 15 from tilting or displacing due to force, ensures the verticality and spacing stability of the side rods 15, and provides a reliable installation benchmark for the smooth sliding of the lifting block 1.
[0021] Both ends of the top beam 12 are equipped with sockets 8, and the upper parts of the two side rods 15 are respectively inserted into the two sockets 8.
[0022] like Figure 1-3 As shown; The upper part of the side rod 15 is inserted into the sockets 8 at both ends of the top beam 12. Through the limiting effect of the sockets 8, the side rod 15 and the top beam 12 are quickly positioned and assembled, ensuring that the connection between the two side rods 15 and the top beam 12 is stable and avoiding the decrease in guiding accuracy caused by assembly deviation.
[0023] Each of the sockets 8 is fitted with a pin 7, which passes through the upper part of the side rod 15 to fix the side rod 15 to the socket 8.
[0024] like Figure 1-3 As shown; The pin 7 passes through the socket 8 and the upper part of the side rod 15, rigidly fixing the side rod 15 and the socket 8 to prevent relative loosening or displacement of the two during the high-frequency vibration of the stamping operation, thus ensuring the stability of the portal frame structure and maintaining the long-term accuracy of the guide system.
[0025] A transverse groove 11 is provided on the top beam 12, and the translation sleeve 9 is slidably connected to the top beam 12 in the left and right directions. The upper part of the hydraulic cylinder 10 is fixed on the translation sleeve 9, and the hydraulic cylinder 10 passes through the transverse groove 11.
[0026] like Figure 1-3 As shown; The translation sleeve 9 can slide left and right along the transverse groove 11 of the top beam 12, driving the hydraulic cylinder 10 to move synchronously, thereby realizing the left and right adjustment of the installation position of the hydraulic cylinder 10.
[0027] The translation sleeve 9 is connected to a fastening screw 6 by a thread, and the fastening screw 6 presses against the top beam 12.
[0028] like Figure 1-3 As shown; The fastening screw 6 presses the top beam 12 through the threaded connection, fixing the translation sleeve 9 in the adjusted target position, preventing the translation sleeve 9 from sliding due to vibration during the stamping process, ensuring the stability of the hydraulic cylinder 10 installation position, and ensuring the accuracy of the driving force transmission.
[0029] The lower end of the hydraulic cylinder 10 is fixed with a plug 4, and the lifting block 1 is fixed with a fixing sleeve 5, with the plug 4 inserted into the fixing sleeve 5.
[0030] like Figure 1-3 As shown; The insert 4 at the lower end of the hydraulic cylinder 10 is inserted into the fixing sleeve 5 of the lifting block 1, so as to realize the quick and detachable connection between the hydraulic cylinder 10 and the lifting block 1. This ensures that the driving force of the hydraulic cylinder 10 can be efficiently transmitted to the lifting block 1, and facilitates later maintenance and replacement.
[0031] A ball 2 is fixed at the lower center of the lifting block 1, and four adjusting screws 3 are threadedly connected to the lifting block 1, with the four adjusting screws 3 evenly distributed around the ball 2.
[0032] like Figure 1-3 As shown; The ball 2 on the lower side of the lifting block 1 serves as the central pivot point. With the four adjusting screws 3 evenly distributed around it, the length of its lower end can be changed by rotating the adjusting screws 3. This allows for fine adjustment of the contact height and level between the lifting block 1 and the upper mold, ensuring that the upper mold is subjected to uniform force and avoiding tilting.
[0033] The stamping die includes a lower die 16, a groove 17 is provided on the lower die 16, a punch 18 is provided above the groove 17, the punch 18 is fixed to the upper die 21, a round bowl 20 is fixed on the upper side of the upper die 21, a ball 2 is rotatably connected to the round bowl 20, and the lower ends of the four adjusting screws 3 are hemispherical, with all four adjusting screws 3 pressing against the upper side of the upper die 21.
[0034] like Figure 1-5 As shown; The sphere 2 is rotatably connected to the bowl 20 of the upper mold 21, providing the upper mold 21 with flexible angle compensation space. The adjusting screws 3 at the lower ends of the four hemispherical shapes tighten the upper mold 21, which not only limits the excessive rotation of the upper mold 21, but also corrects the horizontal accuracy of the upper mold 21 by fine-tuning the adjusting screws 3, ensuring that the punch 18 and the groove 17 of the lower mold 16 are accurately aligned, so that the upper mold can stably move closer to or away from the lower mold.
[0035] Support legs 19 are fixed at the four lower corners of the lower mold 16.
[0036] like Figure 1-5 As shown; The support legs 19 at the four corners of the lower die 16 provide stable support for the entire stamping die, keeping the lower die 16 horizontal and preventing it from tilting due to uneven placement surface. This provides a stable reference platform for the precise relative movement of the upper and lower dies.
