Abstract
Description
Technical Field
[0001] The utility model relates to a PIN needle bending, in particular to a PIN needle special-angle bending die. Background Art
[0002] In industrial production, equipment usage and performance have a crucial impact on production efficiency, product quality, and even overall operational stability. The original equipment used a rotary table machine, which, while meeting production needs to a certain extent, exposed a series of problems during actual use.
[0003] As a multi-station operation, turntable machines are particularly complex in the bending process. The numerous bending stations require precise adjustment and control, which undoubtedly increases the difficulty and complexity of operation. Furthermore, since the connection and coordination between each station require a high degree of coordination, any problem in any link can bring the entire production line to a standstill, affecting the stability and efficiency of the entire production process.
[0004] Furthermore, ensuring the stability of turntable machines is extremely difficult. Due to their complex structure and numerous components, any failure or wear of a component can severely impact the stability of the entire machine. This instability not only reduces production efficiency but can also lead to product quality issues and even threaten operator safety.
[0005] The original equipment used a turntable machine, which was extremely difficult to ensure stability when there were many bending stations and complex processes.
[0006] The current disadvantages of bending PIN needles are as follows:
[0007] 1. The turntable machine is used to cooperate with many bending stations, which is large in size and needs to be coordinated with a rotating mechanism, resulting in large errors between multiple stations;
[0008] 2. The punch moves vertically downward as a punch, punching and bending the PIN terminal. However, some PIN terminals are angled and not horizontal. If the original punch structure is used, it will no longer be applicable. Utility Model Content
[0009] In order to solve the defects of the above-mentioned prior art, the utility model provides a PIN needle special angle bending mold, which reduces the number of workstations, improves quality and efficiency, and also greatly reduces energy consumption, and is suitable for bending at special angles.
[0010] In order to achieve the above technical objectives, the present invention adopts the following technical solutions: a PIN pin special angle bending mold, including station one and station two, both of which include a punch pressure plate, a pressure guide block, a bottom positioning block, and a punch arranged on the punch pressure plate; station two also includes a die; the punch is tilted to be perpendicular to the terminal end face of the PIN pin, the punch passes through the pressure guide block, and the bottom positioning block is used to fix the PIN pin; the die is tilted to pass through the bottom positioning block of station two, and the end of the die supports the terminal of the PIN pin.

[0013] Furthermore, the bottom positioning block is provided with an inclined cavity, the die is passed through the inclined cavity, and a die driving block is provided on the side of the bottom positioning block. The upper end of the die driving block is fixed to the pressure guide block, and the lower end side is provided with a first wedge surface.

When the pressure guide block descends and fits into the bottom positioning block, the first wedge surface drives the second wedge surface so that the movement of the pressure guide block is converted into the movement of the die, so that the die can hit the terminal of the PIN needle.
[0014] Furthermore, a reset groove is provided at the outer end of the inclined cavity, and the reset groove is communicated with the outside world. A large head block is provided at the outer end of the die, and the large head block is provided with a spring groove, and a reset spring is provided in the spring groove.

[0032] Example:
[0033] Figure 1 This is a schematic diagram of a PIN pin special angle bending mold, including station one (right station) and station two (left station). The first bending is performed at station one, and the second bending is performed at station two. Figure 2 yes Figure 1 Left view of Figure 3 yes Figure 2 A cross-sectional view taken along the D-D axis shows that both stations 1 and 2 include a punch platen 1, a pressure guide block 2, a bottom positioning block 3, and a punch 4 mounted on the punch platen 1. Station 2 also includes a die 5. The punch 4 is tilted and perpendicular to the end face of the PIN terminal and passes through the pressure guide block 2. The bottom positioning block 3 is used to secure the PIN. The die 5 is tilted and passes through the bottom positioning block 3 of station 2. The end of the die 5 supports the PIN terminal. The press, upper platen, and lower platen are also included.
[0034] like Figure 3 As shown, the punch pressing plate 1 is provided with an inclined hole 101, and the punch 4 is passed through the inclined hole 101. The lateral dimension of the inclined hole 101 is larger than the lateral projection dimension of the movement of the punch 4, and the vertical dimension is larger than the vertical projection dimension of the movement of the punch 4. The punch 4 moves along its own axial direction. The inclined hole 101 is relatively large and can provide movement space for the punch.
[0035] The pressing guide block 2 is provided with a guide hole, and the punch 4 is inserted into the guide hole. The size of the guide hole is equal to that of the punch 4. The guide hole is used to ensure that the punch moves along its own axis to prevent deviation from the movement and cause PIN bending errors.
[0036] The bottom positioning block 3 is provided with an inclined cavity 301, and the die 5 is passed through the inclined cavity 301. A die driving block 7 is also provided on the side of the bottom positioning block 3. The upper end of the die driving block 7 is fixed to the pressure guide block 2, and the lower end side is provided with a first wedge surface. The outer end of the die 5 is provided with a second wedge surface, and the second wedge surface cooperates with the first wedge surface. When the pressure guide block 2 descends and fits into the bottom positioning block 3, the first wedge surface drives the second wedge surface so that the movement of the pressure guide block 2 is converted into the movement of the die 5, so that the die 5 can hit the terminal of the PIN needle.
[0037] The outer end of the inclined cavity 301 is provided with a reset groove, which is connected to the outside world. The outer end of the die 5 is provided with a big head block, which is provided with a spring groove. A reset spring 6 is provided in the spring groove, and the big head block is placed in the reset groove.
[0038] The bottom positioning block 3 is provided with a die limiting block 8, which is arranged outside the cavity opening of the inclined cavity 301. There is a gap between the limiting surface of the die limiting block 8 and the cavity opening of the inclined cavity 301, so that the die 5 can be withdrawn outward away from the PIN needle.
[0039] The die driving block 7 can drive the die 5 to move inward, and the inclined cavity 301 gives the die 5 a direction of movement so that the die 5 can support the PIN terminal. The spring can reset the die for the next bending, and the limiting surface prevents the die from leaving the inclined cavity 301.
[0040] Figure 4 This is a schematic diagram of the punch and product PIN of station 1, where one of the punches is in a disassembled state. Figure 5 This diagram shows the punch at station two and the product's PIN, with one punch shown disassembled. The PIN is bent from a straight state by punching through two stations within the mold.
[0041] Place the new product in the cavity of the bottom positioning block 3 of the right station one, and place the product taken out from station one in the cavity of the bottom positioning block 3 of the left station two, and lower both pressing guide blocks 2 to stick to the upper surface of the bottom positioning block 3. At this time, the die driving block 7 of station two drives the die 5 to support the PIN needle terminal; the punch 4 is located in the pressing guide block 2, and the punch pressing plate 1 does not fit the pressing guide block 2; then, control the press to move downward, the punch pressing plate 1 gradually fits the pressing guide block 2 downward, and contacts the punch 4, pressing the punch down along its own axis. Since the size of the inclined hole 101 is large enough to accommodate the movement of the punch, complete the first bending of station one and the second bending of station two, open the mold, take out the product of station two and transfer it to the next process, take out the product of station one and put it in station two to continue bending.
[0042] The angle between the terminal of the PIN needle to be bent and the horizontal direction is 18°. Therefore, when bending, the punch of the utility model has vertical movement and tilted movement of 9° on one side during the closing process of the pressing guide block and the punch pressure plate, so that the punch is perpendicular to the surface of the PIN needle but forms an angle of 9° with the movement direction of the mold, completing the precise bending of the PIN needle.
[0043] Before the bending process begins, the worker precisely places the product to be bent into the positioning column (not pictured) at station one. These columns, located within the bottom positioning block, feature a high-precision design that ensures the product remains stable during the bending process, preventing any shifting or shaking. Furthermore, the material of the positioning columns has been carefully selected to ensure sufficient strength and wear resistance without causing any damage to the product.
[0044] At station 2, a high-precision positioning column is also installed to further secure the product. At this point, the pressure device on the production line activates, stamping the products at stations 1 and 2 simultaneously. This pressure device utilizes advanced hydraulic technology to provide stable and powerful stamping force, ensuring that the product is bent to the desired angle and shape.
[0045] This automated and precise production method not only improves the bending accuracy and quality of products, but also significantly increases production efficiency. At the same time, this production method can also reduce the errors and labor intensity of manual operations, making the production line more stable and reliable.
[0046] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
