Description

Technical Field

[0001] The invention relates to the technical field of cemented carbide wire drawing, and in particular to a cemented carbide wire drawing die and a method. Background Art

[0002] Carbide wire drawing refers to a wire drawing die made of carbide material, which is used in the drawing process of metal or other wires. However, the die will be greatly worn after long-term use.

[0003] Currently, one of the important ways to effectively solve the problem of large wear of the mold after long-term use is to set a mold core inside the mold, but this method is relatively cumbersome when replacing the mold core. Summary of the invention

[0004] The object of the present invention is to provide a cemented carbide wire drawing die and method, aiming to solve the technical problem of poor dust removal effect on incoming air flow in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention adopts a cemented carbide wire drawing die, comprising a die body, a die core, a fixing component and a self-locking component, wherein the die core is detachably connected to the die body and is located inside the die body, the fixing component is arranged on one side of the die body, and the self-locking component is arranged on one side of the die body;

[0006] The fixing assembly includes a first placement plate, a second placement plate, a screw, a guide rod, a clamping component and an anti-slip component. The first placement plate is fixedly connected to the mold body and is located on one side of the mold body. The second placement plate is fixedly connected to the mold body and is located on one side of the mold body. The screw is rotatably connected to the first placement plate and is located on the inner side of the first placement plate, and the threads at both ends of the screw have opposite rotation directions. The guide rod is fixedly connected to the second placement plate and is located on the inner side of the second placement plate. The clamping component is arranged on one side of the mold body, and the anti-slip component is arranged on one side of the mold body.

[0007] The first placement plate and the second placement plate fix the positions of the guide rod and the screw rod, and the mold core is placed in the mold body. By rotating the screw rod, the clamping component and the anti-slip component can be driven to move with the cooperation of the guide rod, so as to clamp and fix the mold core. At the same time, reversing the screw rod can cancel the fixation of the mold core by the clamping component, thereby facilitating the removal of the mold core from the mold body.

[0008] The clamping component includes a first clamping block and a second clamping block, the first clamping block is threadedly connected to the screw rod and wraps the screw rod and the guide rod, and the second clamping block is threadedly connected to the screw rod and wraps the screw rod and the guide rod.

[0009] When the first clamping block and the second clamping block move and abut against the mold core, the mold core can be clamped and fixed.

[0010] Among them, the anti-slip component includes a first anti-slip strip and a second anti-slip strip, the first anti-slip strip is fixedly connected to the first clamping block and is located on the inner side of the first clamping block, and the first anti-slip strip is adapted to the outer surface of the mold core, the second anti-slip strip is fixedly connected to the second clamping block and is located on the inner side of the second clamping block, and the second anti-slip strip is adapted to the outer surface of the mold core.

[0011] The first anti-slip strip and the second anti-slip strip can increase the friction force between the first clamping block and the second clamping block when clamping the mold core.

[0012] Among them, the self-locking component includes a worm wheel, a worm and a knob, the worm wheel is fixedly connected to the screw and is located at one end of the screw, the worm is rotatably connected to the mold body and is located on the outside of the mold body, and the worm wheel is rotatably connected to the worm, and the knob is fixedly connected to the worm and is located at one end of the worm away from the mold body.

[0013] Rotating the knob can drive the worm to rotate, and the worm can drive the worm wheel to rotate, thereby driving the screw to rotate. At the same time, the worm wheel and the worm can self-lock, thereby achieving the purpose of locking the fixing component.

[0014] The mold body has a cooling cavity inside, and the cooling cavity wraps the mold core.

[0015] When the cooling cavity is filled with water, the mold core can be cooled.

[0016] Among them, the cemented carbide wire drawing die also includes a water injection pipe and a water injection cover, the water injection pipe is fixedly connected to the die body and is located inside the die body, and the water injection pipe is communicated with the cooling cavity, and the water injection cover is detachably connected to the water injection pipe and is located at one end of the water injection pipe away from the die body.

[0017] Open the water injection cover and inject water into the cooling chamber through the water injection pipe.

[0018] The present invention also provides a cemented carbide wire drawing method, comprising the following steps:

[0019] placing the mold core in the mold body;

[0020] Controlling the fixing assembly to clamp and fix the mold core through the clamping component and the anti-slip component, thereby strengthening the connection between the mold core and the mold body;

[0021] The wire is inserted into the mold core from the end of the mold core with a larger diameter, and the wire is compressed through the area with a smaller diameter inside the mold core, thereby compressing and stretching the wire.

[0022] A cemented carbide wire drawing die and method of the present invention, when installing the die core, the die core is placed in the die body, and the knob is turned to drive the worm to rotate, and the worm can drive the worm wheel to rotate, and the worm wheel will drive the screw to rotate, and with the cooperation of the guide rod, the first clamping block and the second clamping block will be driven to move toward each other to clamp and fix the die core. At the same time, the first anti-slip strip and the second anti-slip strip can prevent slipping. When disassembling the die core, the knob is rotated in the opposite direction so that the first clamping block and the second clamping block no longer clamp and fix the die core, so that the die core can be easily removed, thereby making it more convenient to replace the die core.
