Description

Technical Field

[0001] This utility model relates to traction devices, and more particularly, to a traction device for a high-temperature copper rod. Background Technology

[0002] Currently, Chinese patent CN209756211U discloses a 2800T horizontal double-action forward extrusion press, including four support legs supported by the ground. The tops of the four support legs are fixedly connected to the four corners of the bottom of the worktable. A first support plate is fixedly and vertically installed on one side of the top of the worktable. A circular slot is opened in the middle of the top of the first support plate. A plunger cylinder is fixedly inserted in the circular slot. A first guide rail is fixedly installed at one end of the plunger cylinder. Slide rods are fixedly installed at the four corners of the first guide rail. The middle parts of the four slide rods are slidably inserted and connected to the four corners of the second guide rail. A circular slot is opened on the middle surface of the second guide rail. A guide sleeve of matching size is embedded in the circular slot. The output end of the plunger cylinder passes through the guide sleeve and is inserted and connected to one end of the extrusion cylinder. A return spring is sleeved on the surface of the extrusion cylinder. A second support plate is vertically fixed to the other side of the workbench. An extrusion cylinder is fixedly mounted on the outer wall of the middle section of the second support plate via a sliding rod. The output end of the extrusion cylinder passes through a feeding slot in the middle of the second support plate and is fixedly connected to the middle of the back of the extrusion die. A molding plate is fixedly mounted on the middle of one side of the extrusion die. However, when using the aforementioned forward extrusion press to produce copper rods, workers need to manually pull the extruded copper rods using tools such as pliers, resulting in low automation and low pulling efficiency. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a traction device for a high-temperature copper rod, which has the advantages of high automation and high traction efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a traction device for a high-temperature copper rod, including a support platform, two slide rails arranged side by side at the upper end of the support platform, a sliding seat slidably arranged between the two slide rails, a driving mechanism arranged at the upper end of the support platform, the driving mechanism being connected to the sliding seat and used to drive the sliding seat to slide back and forth along the slide rails, a clamping cavity for the copper rod to be inserted is formed between the sliding seat and the support platform, two clamping blocks are arranged side by side in the clamping cavity, a power mechanism is arranged above the two clamping blocks, the power mechanism being connected to the two clamping blocks and used to drive the two clamping blocks to move closer or further apart.

[0005] With the above technical solution, when using a forward extrusion press to extrude copper ingots for the production of copper rods, the extruded copper rods enter the clamping cavity. At this point, a power mechanism drives two clamping blocks closer together until they are firmly against both ends of the copper rod. Then, a drive mechanism moves a sliding block away from the forward extrusion press along the length of the slide rail to traction the ends of the copper rod, preventing bending or twisting. Using a traction device instead of manual traction by workers offers advantages such as high automation and high traction efficiency.

[0006] Preferably, the drive mechanism includes two ball screw drive units arranged side by side on the upper end of the support platform, and the two ball screw drive units are respectively located on the outer side of the two slide rails.

[0007] With the above technical solution, in use, two drive motors can drive two ball screw drive units to operate, thereby causing the sliding seat to reciprocate along the length of the slide rail. The sliding seat is driven by two ball screw drive units to ensure that it is not prone to deflection or jamming during sliding. The two ball screw drive units are located on the outer sides of the two slide rails, and this arrangement makes it less likely for the ball screw drive units to come into contact with the copper rod, thus minimizing obstruction to the traction process of the copper rod.

[0008] Preferably, the power mechanism includes a servo motor fixedly mounted on the sliding seat, a power gear fixedly mounted on the output end of the servo motor, and a power rack fixedly mounted on the side wall of the clamping block. The power rack is slidably connected to the sliding seat, and the two power racks are centrally symmetrically arranged on both sides of the power gear.

[0009] Through the above technical solution, the servo motor drives the power gear to rotate, and the power gear drives the two clamping blocks to move synchronously through two power racks respectively.

[0010] Preferably, the servo motor is fixedly mounted on the upper end of the sliding seat, the output end of the servo motor passes downward through the sliding seat, and the power gear is located in the clamping cavity.

[0011] With the above technical solution, the servo motor is installed on the upper end of the sliding base, making the installation process relatively convenient.

[0012] Preferably, a limiting sleeve is provided on the inner side of the sliding seat opposite to the power rack, and an avoidance opening is provided through the side wall of the limiting sleeve along the length direction. The power rack is slidably connected in the corresponding limiting sleeve, and the transmission teeth of the power rack pass through the avoidance opening.

[0013] Through the above technical solution, the limiting sleeve can not only support the power rack, but also limit and guide the sliding of the power rack.

[0014] Preferably, a connecting piece is fixedly provided at the end of the power rack, and the connecting piece is pressed and fixed to the corresponding clamping block by bolts.

[0015] With the above technical solution, the power rack is pressed and fixed by the connecting piece and the clamping block, making disassembly and assembly more convenient.

[0016] Preferably, the connecting piece is provided with a waist-shaped adjustment hole, and the threaded section of the bolt passes through the corresponding waist-shaped adjustment hole.

[0017] Through the above technical solution, the waist-shaped adjustment hole and the bolt cooperate with each other to change the relative position of the power rack and the clamping block, so as to adapt to copper rods of different diameters, thereby improving the applicability of the above traction device.

[0018] Preferably, the opposite sides of the two clamping blocks are clamping sides, and the clamping sides are provided with an arc-shaped opening along the length direction of the slide rail.

[0019] With the above technical solution, when the copper rod is clamped by the two clamping blocks, the upper and lower ends of the arc-shaped opening abut against the outer wall of the copper rod to limit the movement of the copper rod. Attached Figure Description
