A clamping mechanism for copper alloy machining

Abstract

This utility model discloses a clamping mechanism for copper alloy processing, comprising two symmetrical clamping and conveying devices. Each clamping and conveying device includes two sprockets and a chain. Clamps are equidistantly hinged to the chain. Each clamp includes a U-shaped frame with two symmetrical clamping plates inside. The front ends of the clamping plates extend from the opening of the U-shaped frame, and the clamping plates are connected to the inner wall of the U-shaped frame by springs. This utility model uses a symmetrically arranged clamping structure to hold the workpiece, and the clamping structure reciprocates through the sprockets and chain. This ensures that the workpiece is continuously clamped by clamps on both sides and pushed forward, thus replacing manual workpiece support. This not only prevents workpiece displacement but also increases workpiece transport efficiency.

Description

Technical Field

[0001] This utility model relates to the field of copper plate and strip technology, specifically a clamping mechanism for copper alloy processing. Background Technology

[0002] Copper alloy plates are produced by rolling copper alloy ingots using a rolling mill. Currently, when rolling copper alloy plates in the workshop, the workpieces are manually supported at both the inlet and outlet ends. Especially at the outlet end, manual support requires pulling the workpieces to move. This manual operation not only easily injures workers but also easily causes the workpieces to shift during the rolling process, resulting in the workpieces failing to meet processing requirements and increasing the defect rate.

[0003] Therefore, in order to correct the above-mentioned defects, we propose a clamping mechanism for copper alloy machining. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a clamping mechanism for copper alloy processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping mechanism for copper alloy processing, comprising two symmetrical clamping and transferring devices. Each clamping and transferring device includes two sprockets and a chain, with clamps equidistantly hinged to the chain.

[0006] The clamp includes a U-shaped frame with two symmetrical clamping plates inside. The front ends of the clamping plates extend from the opening of the U-shaped frame, and the clamping plates are connected to the inner wall of the U-shaped frame by springs.

[0007] Furthermore, a guide rod is fixed to the side of the clamp facing the inner wall of the U-shaped frame, and the guide rod moves through the U-shaped frame.

[0008] Furthermore, the front ends of the two symmetrical clamps form a figure-eight shape.

[0009] Furthermore, the clamping and moving device also includes guard plates located above and below the chain, with the U-shaped frame moving in a circular motion between the two guard plates following the chain.

[0010] Furthermore, guide wheels are fixed at both the upper and lower ends of the U-shaped frame, and the upper and lower guide wheels are in contact with the upper and lower guard plates respectively.

[0011] Furthermore, grooves are provided on the opposite surfaces of the two clamping plates, and a bearing is installed in the groove of the lower clamping plate, with a guide roller installed on the bearing.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the utility model adopts a symmetrically arranged clamping structure to hold the workpiece, and the clamping structure moves in a cyclic reciprocating motion through a sprocket and chain. In this way, the workpiece is continuously clamped by clamps on both sides and pushed forward, thereby replacing the worker in supporting the workpiece. This not only prevents the workpiece from shifting, but also speeds up the workpiece transportation efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides a technical solution:

[0019] Please see Figure 1-3 A clamping mechanism for copper alloy processing includes two symmetrical clamping and transferring devices. Each clamping and transferring device is supported by two support seats 5, and a drive motor is installed inside the support seats 5. The clamping and moving device includes two sprockets 1 and a chain 2. Clamps 4 are hinged at equal intervals on the chain 2. The two support seats 5 support a lower guard plate 3. The drive shaft of the drive motor passes through the guard plate 3 and is connected to the sprockets 1. The upper end of the sprockets 1 is connected to the upper guard plate 3 through a shaft.

[0020] The clamp 4 includes a U-shaped frame 41, which has two symmetrical clamping plates 42 inside. The front end of the clamping plate 42 extends out from the opening of the U-shaped frame 41. The clamping plate 42 is connected to the inner wall of the U-shaped frame 41 by a spring 43. A guide rod 44 is also fixed on the side of the clamping plate 42 facing the inner wall of the U-shaped frame 41. The guide rod 44 moves through the U-shaped frame 41.

[0021] When the workpiece extends out from the outlet end of the calendering equipment, the chain 2 drives the clamp 4 on it to move continuously. The end of the clamping and moving device that is close to the calendering equipment is set as end A, and the other end is end B. End A always has two clamps 4 in contact with both sides of the workpiece, and bites the workpiece and moves it forward. When clamping, the clamps turn from the sprocket 1 at end A, so that the openings of the two symmetrical clamping plates 42 are aligned with the workpiece. Under the action of the spring 43, the two symmetrical clamping plates 42 clamp the workpiece.

[0022] Among them, the clamps 4 on the left and right sides are one-to-one corresponding.

[0023] In order to allow the edge of the workpiece to quickly enter between the two symmetrical clamps 42, the front ends of the two symmetrical clamps 42 form a figure-eight structure to increase the entry space.

[0024] Since chain 2 is used for transmission, considering the stability during the transmission process, the clamping and moving device also includes guard plates 3 located above and below chain 2. The U-shaped frame 41 moves in a circular motion with chain 2 between the two guard plates 3. Guide wheels 45 are fixed at the upper and lower ends of the U-shaped frame 41, and the upper and lower guide wheels 45 contact the upper and lower guard plates 3 respectively.

[0025] That is, the clamp 4 moves between the upper and lower guard plates 3 via the upper and lower guide wheels 45.

[0026] Considering the limitation on the copper alloy plate, grooves are provided on the opposite surfaces of the two clamping plates 42. A bearing 46 is installed in the groove of the lower clamping plate 42, and a guide roller 47 is installed on the bearing 46. That is, when the workpiece enters between the two clamping plates 42, the guide roller 47 between the two clamping plates 42 limits the workpiece from the side to prevent the workpiece from deviating.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
