Description

Technical Field

[0001] The utility model belongs to the technical field of terminal production, and particularly relates to a terminal stamping die. Background Art

[0002] Terminals are important components in the electrical and electronic fields, used to connect wires or cables to form connections between circuits or electronic devices. Terminals are the basic components of electrical connections and are widely used in various industrial, commercial, and household environments. Correct selection and use of terminals are crucial for ensuring the performance and safety of electrical systems. In the terminal stamping production process, die design and manufacturing are key steps, which need to consider requirements such as the shape and size of the terminals, as well as factors such as the service life and processing accuracy of the die.

[0003] However, there are some problems in the existing technology: currently, this flat shape is obtained by using large materials and cutting off the excess materials multiple times to obtain the finished material. This processing method that requires multiple cuttings has a low utilization rate, high cost, and low efficiency, thus having certain limitations. Moreover, for the stamping equipment used in the current market for terminal production, when stamping the material into a terminal, it is difficult to control the shape, size, and symmetry of the terminal. Therefore, we propose a terminal stamping die. Summary of the Utility Model

[0004] Aiming at the problems existing in the existing technology, the purpose of the utility model is to provide a terminal stamping die. Through the mutual cooperation of the shaping inclined plane and two groups of positioning clamping plates, the stamping equipment can stamp the cylindrical terminal raw material into shape at one time, which can not only effectively improve the quality and production efficiency of the terminal body after stamping, but also effectively reduce the production cost.

[0005] The utility model is realized as follows. A terminal stamping die includes:

[0006] A stamping seat, on the upper surface of which a lower die is provided. An upper die is arranged on the upper surface of the stamping seat in a lifting manner, and the upper die and the lower die are arranged in correspondence.

[0007] A positioning component, which is arranged on the upper surface of the lower die. The upper surface of the lower die is detachably connected with a terminal body through the positioning component.

[0008] Positioning clamping plates, two groups of which are provided, and the two groups of positioning clamping plates are symmetrically arranged on the upper surface of the lower die, and the terminal body is located between the two groups of positioning clamping plates.

[0009] Optionally, shaping inclined planes are formed in the middle of the opposite sides of the upper die and the lower die, so that the cylindrical end of the terminal body is suspended at one end of the upper surface of the lower die through the positioning component.

[0010] Optionally, the positioning component includes a first positioning block and a second positioning block. The first positioning block and the second positioning block are symmetrically arranged at both ends of the upper surface of the lower mold. The first positioning block and the second positioning block are both L-shaped, and the opposite ends of the first positioning block and the second positioning block are arranged at the same horizontal level. The terminal body is detachably arranged on the upper surface of the lower mold through the first positioning block and the second positioning block.

[0011] Optionally, positioning grooves are formed at both ends of the upper surface of the lower mold. The first positioning block and the second positioning block are both movably arranged inside the positioning grooves, and an adjusting mechanism is arranged inside the positioning grooves. The first positioning block and the second positioning block are close to or away from each other through the adjusting mechanism.

[0012] Optionally, mounting grooves are formed in the middle of both sides of the upper surface of the lower mold, and the mounting grooves are located on one set of shaping inclined surfaces. The two positioning clamping plates are both arranged inside the mounting grooves, and the upper ends of the two positioning clamping plates both extend out of the inside of the mounting grooves.

[0013] Optionally, a fitting inclined surface is formed at one end of the upper surface of each of the two positioning clamping plates, and the fitting inclined surface is correspondingly fitted with the other set of shaping inclined surfaces. A horizontal surface is formed at the other end of the upper surface of the positioning clamping plate, and the horizontal surface is arranged at the same horizontal level as one end of the bottom of the upper mold. A fitting plane is formed at one end of the opposite sides of the two positioning clamping plates for fitting the outer side of the terminal body, and a shaping inclined surface is formed at the other end of the opposite sides of the two positioning clamping plates.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. Through the mutual cooperation of the shaping inclined surfaces and the two positioning clamping plates, when the terminal raw material is placed on the lower mold, the upper mold and the lower mold can directly stamp the terminal raw material into a terminal finished product with one end being flat and the other end being cylindrical, so that it is not necessary to perform cutting production multiple times. Therefore, the working efficiency and production cost of the terminal stamping die are further improved.

[0016] 2. Through the arranged positioning component, the terminal raw material can be effectively stabilized on the upper surface of the lower mold, thereby further avoiding the situation of dislocation of the terminal raw material during the stamping process.

Detailed implementation manners

[0024] To further understand the content, features and effects of the present utility model, the following embodiments are listed and described in detail with the accompanying drawings as follows.

[0025] As Figures 1 to 5 shown, a terminal stamping die provided by an embodiment of the present utility model includes: a stamping seat 1, a lower die 3 is arranged on the upper surface of the stamping seat 1, an upper die 2 is arranged on the upper surface of the stamping seat 1 in a lifting manner, and the upper die 2 and the lower die 3 are arranged in a corresponding manner; a positioning component 4, the positioning component 4 is arranged on the upper surface of the lower die 3, and a terminal body 9 is detachably connected to the upper surface of the lower die 3 through the positioning component 4;

[0026] As Figures 1 to 5 shown, due to the design that the terminal body 9 is detachably arranged on the upper surface of the lower die 3 through the positioning component 4, when the terminal body 9 is being stamped and formed, the positioning component 4 can increase the stability of the terminal body 9, thereby further improving the quality of the terminal body 9 after stamping and forming.

[0027] Positioning clamping plates 6, there are two groups of positioning clamping plates 6, and the two groups of positioning clamping plates 6 are symmetrically arranged on the upper surface of the lower die 3, and the terminal body 9 is located between the two groups of positioning clamping plates 6;

[0028] As Figures 1 to 5 shown, through the design of the two groups of positioning clamping plates 6 provided, during the stamping process of the terminal body 9, the two groups of positioning clamping plates 6 can not only assist the positioning component 4 to stabilize the terminal body 9 and improve the stability of the terminal body 9 during the stamping process, but also limit the flattened position of the terminal body 9 during stamping, thereby shaping the flattened position of the terminal body 9 and preventing the flattened end of the terminal body 9 from deforming.

[0029] Furthermore, shaping inclined surfaces 5 are formed in the middle of the opposite sides of the upper die 2 and the lower die 3, so that the cylindrical end of the terminal body 9 is suspended at one end of the upper surface of the lower die 3 through the positioning assembly 4;

[0030] As Figures 1 to 5 shown, due to the design that the cylindrical end of the terminal body 9 is suspended at one end of the upper surface of the lower die 3 through the positioning assembly 4, when the terminal body 9 is not stamping formed, the whole is cylindrical. And because of the shaping inclined surface 5 formed on the upper surface of the lower die 3, a part of the terminal body 9 will be suspended on the upper surface of the lower die 3. The positioning assembly 4 can fix the terminal body 9. Therefore, when the upper die 2 performs stamping, the suspended part of the terminal body 9 will not be flattened by stamping due to the limited position below. Therefore, with the mutual cooperation of the positioning assembly 4 and the shaping inclined surface 5, the terminal body 9 can be stamping formed once stably, so that the working efficiency of the terminal stamping die can be effectively improved and there is no need for multiple cutting processes. Therefore, the production cost of the terminal body 9 is further reduced.

[0031] Furthermore, the positioning assembly 4 includes a first positioning block 401 and a second positioning block 402. The first positioning block 401 and the second positioning block 402 are symmetrically arranged at both ends of the upper surface of the lower die 3. The first positioning block 401 and the second positioning block 402 are both arranged in an L shape, and the opposite ends of the first positioning block 401 and the second positioning block 402 are arranged at the same horizontal level. The terminal body 9 is detachably arranged on the upper surface of the lower die 3 through the first positioning block 401 and the second positioning block 402; positioning grooves 7 are opened at both ends of the upper surface of the lower die 3. The first positioning block 401 and the second positioning block 402 are both movably arranged inside the positioning grooves 7, and an adjusting mechanism is arranged inside the positioning grooves 7. The first positioning block 401 and the second positioning block 402 are both close to or away from each other through the adjusting mechanism; installation grooves 8 are opened in the middle of both sides of the upper surface of the lower die 3, and the installation grooves 8 are located on one set of shaping inclined surfaces 5. Two groups of positioning clamping plates 6 are arranged inside the installation grooves 8, and the upper ends of the two groups of positioning clamping plates 6 both extend out of the inside of the installation grooves 8;

[0032] It should be noted that the structure in which the first positioning block 401 and the second positioning block 402 approach or separate from each other through the adjusting mechanism can be realized by structures such as threads or pins. At present, the common technical means in the market to control the first positioning block 401 and the second positioning block 402 to approach each other to fix the terminal body 9 is not elaborated in this utility model.

[0033] As Figures 2 to 5As shown, due to the L-shaped design of both the first positioning block 401 and the second positioning block 402, the ends of the first positioning block 401 and the second positioning block 402 that contact the terminal body 9 are at the same horizontal level. Therefore, the terminal body 9 can be fixed more stably, thereby further improving the quality of the terminal body 9 after stamping.

[0034] Furthermore, at one end of the upper surface of each of the two groups of positioning clamping plates 6, a fitting inclined surface 603 is formed, and the fitting inclined surface 603 is arranged in corresponding fitting with the shaping inclined surface 5 of the other group. At the other end of the upper surface of the positioning clamping plate 6, a horizontal surface 604 is formed, and the horizontal surface 604 is at the same horizontal level as one end of the bottom of the upper die 2. At one end of the opposite sides of the two groups of positioning clamping plates 6, a fitting plane 601 is formed for fitting the outside of the terminal body 9, and at the other end of the opposite sides of the two groups of positioning clamping plates 6, a shaping inclined surface 602 is formed;

[0035] As Figures 1 to 4 shown, through the mutual cooperation of the fitting inclined surface 603 and the horizontal surface 604, when the upper die 2 presses downward, the uneven surfaces at both ends of the lower surface of the upper die 2 due to the shaping inclined surface 5 can be more stably attached to the upper surface of the lower die 3. Therefore, not only can the stability of the upper die 2 when stamping the terminal body 9 be effectively improved, but also the quality of the terminal body 9 after stamping can be effectively improved.

[0036] As Figures 1 to 4 shown, through the design of the fitting plane 601, the fitting plane 601 can stably fit on the outside of the non-stamped terminal body 9, thereby further improving the stability of the terminal body 9 during the stamping process.

[0037] As Figures 1 to 4 shown, through the design of the shaping inclined surfaces 602, the two shaping inclined surfaces 602 cooperate with each other. When the terminal body 9 is stamped and shaped, the shaping inclined surfaces 602 can ensure the positioning of the outside of the terminal body 9 that needs to be stamped into a flat end. Therefore, the situation where the arc surfaces formed on both sides of the terminal body 9 have different arc angles due to stamping can be avoided, thereby better improving the practicability of the terminal body 9.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
