Description

Technical Field

[0001] This utility model relates to the field of cold stamping die technology, and in particular to a stretching structure with auxiliary positioning adjustment. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials into parts. They are called cold stamping dies. Drawing dies are a type of stamping die, and their function is to change the shape and size of the workpiece by stamping.

[0003] The existing equipment stretches the metal material into place during processing, requiring another device to stamp the side wall of the workpiece. This facilitates continuous processing of the workpiece but affects processing efficiency. Moreover, when stamping and stretching the stretched workpiece, the limiting effect on the stamped workpiece is poor, and the position of the part is prone to movement during stamping, resulting in unqualified stretching dimensions.

[0004] Therefore, this application proposes a stretching structure with auxiliary positioning adjustment to solve the problems in the prior art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tension structure with auxiliary positioning adjustment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tensioning structure with auxiliary positioning adjustment includes a base plate, a positioning mechanism, and a tensioning mechanism.

[0008] A hydraulic cylinder is fixedly installed on the top of the base plate. The output end of the hydraulic cylinder is provided with a positioning mechanism. A tensioning mechanism is provided on the base plate and corresponds to the positioning mechanism.

[0009] The positioning mechanism includes a stamping block, a protective fork, and a rectangular block. The output end of the hydraulic cylinder is fixedly connected to the stamping block. The protective fork is slidably connected inside the stamping block. A rectangular block is welded to the top of the protective fork. A machined part is installed inside the protective fork. A rectangular groove is opened on the top of the machined part and corresponds to the rectangular block.

[0010] The stretching mechanism includes guide rods, pressure plates, sliding legs, drive blocks, stamping heads, and springs. Multiple guide rods are fixedly connected to the top of the base plate. Through the coordinated design of the hydraulic cylinder one, positioning mechanism, stretching mechanism, sleeve, die, hydraulic cylinder two, and ejector rod, not only can the workpiece be stretched, but the sidewalls of the workpiece can also be stamped, enabling continuous processing and improving processing efficiency. Furthermore, it provides auxiliary positioning for the workpiece, preventing movement and improving product quality.

[0011] Specifically, a single pressure plate is slidably connected to multiple guide rods, and multiple driving blocks are slidably connected within the pressure plate. A stamping head is fixedly mounted at one end of each of the driving blocks. The stamping blocks interact with the pressure plate, causing the pressure plate to move synchronously downwards a certain distance, compressing multiple springs. During this process, the pressure plate drives the multiple driving blocks to move synchronously. Simultaneously, the multiple driving blocks interact with multiple sliding legs, causing them to move synchronously towards the die. Simultaneously, the multiple driving blocks drive the multiple stamping heads to move synchronously, with one end of each stamping head engaging with the die, thereby achieving the effect of stamping the sidewall of the workpiece.

[0012] Specifically, a plurality of sliding legs are fixedly connected to the base plate, and the plurality of sliding legs are slidably connected to a plurality of driving blocks respectively. Each of the plurality of driving blocks has an inclined groove, and the plurality of sliding legs slide in the plurality of inclined grooves respectively. The effect of guiding and driving the plurality of driving blocks is achieved by the action of the plurality of sliding legs.

[0013] Specifically, the pressure plate has multiple through holes, and one end of each of the multiple sliding legs passes through the multiple through holes to facilitate the up and down movement of the pressure plate.

[0014] Specifically, springs are fixedly sleeved on each of the guide rods, and one end of each spring is fixedly connected to the pressure plate. The pressure plate is restored to its original shape by the elastic potential energy of the springs.

[0015] Specifically, a hydraulic cylinder 2 is fixedly installed on the top of the base plate, and two push rods are fixedly installed on the output end of the hydraulic cylinder 2. Multiple through holes 2 are opened on the die, and the two push rods slide in the two through holes 2 respectively. Under the drive of the hydraulic cylinder 2 and the cooperation between the die and the protective fork, the workpiece can be stretched.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] (1) The present invention provides a tension structure with auxiliary positioning adjustment. Through the cooperative design between the protective fork, rectangular block, workpiece and stamping block, the workpiece can be positioned to prevent it from moving and improve product quality.

[0018] (2) The present invention provides a stretching structure with auxiliary positioning adjustment. Through the cooperative design between the hydraulic cylinder one, positioning mechanism, stretching mechanism, round sleeve, die, hydraulic cylinder two and ejector rod, it can not only achieve the effect of stretching the workpiece, but also achieve the effect of stamping the side wall of the workpiece, thereby achieving the effect of continuous processing of the workpiece and improving processing efficiency.

[0030] The stretching mechanism includes guide rods 4, pressure plates 5, sliding legs 12, drive blocks 13, stamping heads 14, and springs 15. Multiple guide rods 4 are fixedly connected to the top of the base plate 1. Through the coordinated design of hydraulic cylinder 1 6, positioning mechanism, stretching mechanism, round sleeve 2, die 3, hydraulic cylinder 2 16, and ejector rod 17, it can not only achieve the effect of stretching the workpiece 9, but also achieve the effect of stamping the side wall of the workpiece 9, thereby achieving the effect of continuous processing of the workpiece 9, improving processing efficiency. Moreover, it can achieve the effect of auxiliary positioning of the workpiece 9, preventing the workpiece 9 from moving and improving product quality.

[0031] In this embodiment, a single pressure plate 5 is slidably connected to multiple guide rods 4. Multiple drive blocks 13 are slidably connected inside the pressure plate 5. A stamping head 14 is fixedly installed at one end of each drive block 13. The stamping blocks 7 interact with the pressure plate 5, causing the pressure plate 5 to move downward synchronously by a certain distance, and compressing multiple springs 15. During this process, the pressure plate 5 drives multiple drive blocks 13 to move synchronously. At the same time, multiple drive blocks 13 interact with multiple sliding legs 12, causing multiple drive blocks 13 to move synchronously towards the die 3 by a certain distance. Simultaneously, multiple drive blocks 13 drive multiple stamping heads 14 to move synchronously, and one end of each stamping head 14 engages with the die 3, thereby achieving the effect of stamping the side wall of the workpiece 9.

[0032] In this embodiment, a plurality of sliding legs 12 are fixedly connected to the base plate 1. The plurality of sliding legs 12 are slidably connected to a plurality of driving blocks 13 respectively. Each of the driving blocks 13 has an inclined groove. The plurality of sliding legs 12 slide in the inclined groove respectively. The effect of guiding and driving the plurality of driving blocks 13 is achieved by the action of the plurality of sliding legs 12.

[0033] In this embodiment, the pressure plate 5 has multiple through holes, and one end of each of the multiple sliding legs 12 passes through the multiple through holes to facilitate the up and down movement of the pressure plate 5.

[0034] In this embodiment, multiple guide rods 4 are all fixedly fitted with springs 15, and one end of each spring 15 is fixedly connected to the pressure plate 5. The pressure plate 5 is restored to its original state by the elastic potential energy of the springs 15. The pressure plate 5 has multiple through holes 3, and multiple guide rods 4 and springs 15 are respectively pre-set to be adapted to each other.

[0035] In this embodiment, a hydraulic cylinder 16 is fixedly installed on the top of the base plate 1. Two push rods 17 are fixedly installed on the output end of the hydraulic cylinder 16. Multiple through holes 2 are opened on the die 3. The two push rods 17 slide in the two through holes 2 respectively. Driven by the hydraulic cylinder 16 and with the cooperation between the die 3 and the protective fork 8, the workpiece 9 can be stretched.

[0036] Working principle: First, the workpiece 9 is placed inside the circular sleeve 2, with the rectangular groove 11 on the workpiece 9 corresponding to the rectangular block 10. Then, under the extension drive of the hydraulic cylinder 6, the protective fork 8 is inserted into the circular sleeve 2 and acts on the workpiece 9. Simultaneously, through the drive of the hydraulic cylinder 16 and the transmission of the two push rods 17, the die 3 slides inside the circular sleeve 2 and acts on the workpiece 9. At this time, the cooperation between the protective fork 8 and the die 3 achieves the effect of stretching the workpiece 9. During this process, the rectangular block 10 is inserted into the rectangular groove 11. At this time, through the cooperation between the rectangular block 10 and the rectangular groove 11, the workpiece 9 can be positioned, preventing the workpiece 9 from moving and improving product quality.

[0037] Then, the hydraulic cylinder 6 drives the stamping block 7 to move downwards and drives the protective fork 8 to move synchronously. During this process, the protective fork 8 first sets the workpiece 9 onto the die 3. Then, the protective fork 8 interacts with the round sleeve 2 and slides a certain distance inside the stamping block 7. At the same time, the stamping block 7 interacts with the pressure plate 5 and causes the stamping plate 5 to move downwards synchronously, compressing multiple springs 15. During this process, the stamping plate 5 drives multiple driving blocks 13 to move synchronously. At the same time, the multiple driving blocks 13 interact with multiple sliding legs 12, causing the multiple driving blocks 13 to move synchronously towards the die 3. Simultaneously, the multiple driving blocks 13 drive multiple stamping heads 14 to move synchronously, and one end of each stamping head 14 engages with the die 3, thereby achieving the effect of stamping the side wall of the workpiece 9. This enables continuous processing of the workpiece 9 and improves processing efficiency.

[0038] Finally, the workpiece 9 is ejected from the sleeve 2 by the drive of the hydraulic cylinder 16 and the cooperation of the ejector rod 17 and the die 3, thus completing the processing.

[0039] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, not only can the continuous processing of the workpiece 9 by stretching and sidewall stamping be achieved, but the workpiece 9 can also be limited, thereby improving processing efficiency and product quality. Moreover, the structure is simple and the practicality is higher.
