Description

Technical Field

[0001] The utility model relates to the technical field of copper bar processing, and more specifically, to a fixed-length tooling for punching copper bars for electricians. Background Art

[0002] Copper bars are large-current conducting products, applicable to electrical engineering such as high- and low-voltage electrical appliances, switch contacts, power distribution equipment, busbars, etc., and are also widely used in large-current electrolytic smelting projects such as metal smelting, electroplating, and chemical caustic soda. Electrician copper bars have advantages such as low resistivity and large bendability. They are long conductors with a rectangular or chamfered (rounded) rectangular cross-section. Nowadays, rounded copper bars are generally used, and high surface quality requirements are needed to avoid tip discharge. During production, since their width and thickness have been selected, only the corresponding length needs to be intercepted. Machines of the same batch or the same type require the same length for good appearance. In the usual copper bar production, before punching each copper bar, the length is measured first, then one is punched, then it is continued inside, then the length is measured again or compared with the punched copper bar, and then another one is punched, and so on. Therefore, this method has a large labor intensity of operation, a large length error, and the quality cannot be well guaranteed, affecting the product appearance. Summary of the Utility Model

[0013] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0014] Embodiment

[0015] Please refer to the attached drawings of the specification. In the embodiment of the present utility model, a length - determining tooling for punching copper bars for electricians includes a workbench surface 1. A tooling bottom plate 2 is fixedly installed on the workbench surface 1. A T - shaped groove 3 is formed on the tooling bottom plate 2. A T - shaped block 6 that can slide along the direction of the T - shaped groove 3 is provided on the T - shaped groove 3. A T - shaped bolt 7 is arranged in the T - shaped groove 3. The T - shaped block 6 is connected to the T - shaped bolt 7 through a threaded hole. The stud of the T - shaped bolt 7 passes upward through the T - shaped block 6. A nut flat washer 8 is provided at the upper end of the T - shaped bolt 7. Tightening the nut flat washer 8 fixes the position of the T - shaped block 6 on the T - shaped groove 3. On one side of the T - shaped groove 3, a width positioning plate 9 is installed on the upper surface of the tooling bottom plate 2. A punching knife 11 is vertically installed on one side of the workbench surface 1 away from the tooling bottom plate 2.

[0016] Specifically, a plurality of counter - sunk holes 4 are formed on both sides of the tooling bottom plate 2. The tooling bottom plate 2 is fixedly installed on the workbench surface 1 through the counter - sunk holes 4 by bolts.

[0017] Furthermore, three groups of mutually parallel T - shaped grooves 3 are provided. A plurality of threaded holes 5 are provided on the tooling bottom plate 2 on both sides of the T - shaped grooves 3. A width positioning screw 10 is connected in the threaded hole 5 through threads. The width positioning plate 9 is installed on the tooling bottom plate 2 through the threaded holes 5 and the width positioning screws 10. The hole on the width positioning plate 9 for the width positioning screw 10 to pass through is a long - strip hole, which is convenient for adjusting the left - right position of the width positioning plate 9.

[0018] The tooling bottom plate 2 is made with a T - shaped groove 3. The T - shaped block 6 is installed in the groove, and the T - shaped bolt 7 is installed in the T - shaped block 6, which is used to adjust the length of the copper bar. After adjusting the length, tighten it with a nut. There are three T - shaped grooves in total, which are used for different positions of the punching knife direction. The tooling bottom plate 2 is also machined with threaded holes 5 for installing the width positioning plate 9. After adjusting the position, fix it with width positioning screws 10. The tooling bottom plate 2 is also machined with counter - sunk holes 4 for installing and fixing it on the workbench surface 1. Not all of the counter - sunk holes 4 need to be utilized. By using different counter - sunk holes 4 for fixing, the tooling bottom plate 2 can be adjusted back and forth along the direction of the copper bar, expanding the range of length adjustment.

[0019] Usage process:

[0020] In use, first fix the tooling base plate 2 on the workbench surface 1 with screws. Then loosen the nut on the T-bolt 7 and adjust the position of the T-block 6 along the direction of the T-slot 3 to make the length of the copper bar meet the requirements. Tighten the nut on the T-bolt 7. Then loosen the width positioning screw 10 and adjust the position of the width positioning plate 9 to adapt to the width requirement of the copper bar. Tighten the width positioning screw 10. After these two adjustments are completed, the copper bar punching work can be started. During work, pass the copper bar blank through under the punching knife and against the T-block 6, and the other side is closely against the width positioning plate 9. At this time, the length is already appropriate. Start the punching knife to punch a copper bar. Take away the finished copper bar and repeat the above steps to punch the second copper bar, and so on.

[0021] In the above process, the T-block can move along the direction of the T-slot to adjust the length of the copper bar for punching. The width positioning plate can adapt to the widths of different copper bars, has good compatibility with copper bars of different specifications, can ensure that the lengths of copper bars in the same batch or of the same type are consistent, with stable quality, good appearance, simple structure, easy to operate, and can be completed by one person, greatly reducing the labor intensity and reducing the cycle time. There are a total of three T-slots, which are suitable for punching knives with different directions of the punching knife edges, further expanding the scope of application. The structure of this application is simple, highly practical, and easy to operate, worthy of promotion.
