TECHNICAL FIELD
[0001] The application relates to the technical field of cutting and flattening molds, in particular to a lead cutting and flattening mold. BACKGROUND
[0002] In industrial production, special leads are often needed, and the cut position of the lead needs to be flattened. When the cut position of the lead is flattened by a flattening machine, the material of the lead is extruded in the axial direction under the pressure of the flattening machine, so that the break of the output lead is uneven, and the surface quality of the tablet is poor.
[0003] The lead includes a steel wire and a copper wire, and a through hole is formed in the middle of the steel wire. The copper wire is in interference fit with the through hole. The cut of the lead is manually removed after being flattened by a tablet press. The worker places the steel wire in a special wire slot, and then the worker cuts off the part of the tablet protruding from the wire slot by a guillotine, so as to realize the cutting and flattening of the tablet break.
[0004] In the above cutting and flattening mode, the length and size of the steel wire cannot be kept consistent, and the size of the steel wire needs to be further adjusted manually, which needs to be improved. CONTENT OF THE UTILITY MODEL
[0005] In order to make the length and size of the steel wire consistent after cutting and flattening, the application provides a lead cutting and flattening mold.
[0006] The application provides a lead cutting and flattening mold, which adopts the following technical scheme:
[0007] A lead cutting and flattening mold, comprising a base, a flattening piece arranged on the base, a cutter piece in sliding connection with the base, a wire feeding mechanism arranged on the base, and a driving piece in rotary connection with the sidewall of the base, wherein the flattening piece, the cutter piece and the wire feeding mechanism are controlled by the driving piece, the wire feeding mechanism is located on one side of the flattening piece, the cutter piece is located on the other side of the flattening piece, and the cutter piece and the flattening piece are in abutment on the side away from the wire feeding mechanism.
[0008] By adopting the above technical scheme, when the worker cuts and flattens the lead, the worker installs the lead on the base, and then passes the lead through the wire feeding mechanism. Under the wire feeding action of the wire feeding mechanism, the lead slides into the inner wall of the flattening piece. At this time, the main shaft drives the flattening piece to perform flattening work on the end of the lead. Then the main shaft drives the cutter piece to cut and flatten the lead break. Then the wire feeding mechanism continues to advance the lead, and the flattening machine performs flattening work on the lead again. The cutter piece cuts off the front segment of the lead. Then the above cycle is repeated, which realizes the consistency of the length and size of the steel wire after cutting and flattening.
[0009] Optionally, the flattening piece comprises a flattening block and a first driving rod, the base is fixed with a supporting block, the first driving rod is rotationally connected with the supporting block, one end of the first driving rod is fixed with the upper side of the flattening block, and the other end of the first driving rod is close to the driving piece.
[0010] By adopting the above technical scheme, the flattening block directly acts on the lead wire, ensuring the flatness before cutting. Since the flattening block is fixedly connected with the first driving rod, the stability during the flattening process is improved. The other end of the first driving rod is close to the driving piece, so that the driving piece can directly drive the first driving rod to rotate. This setting reduces the length of the transmission chain, improves the driving efficiency, and reduces the energy loss during the driving process.

[0012] By adopting the above technical scheme, when the cutter piece cuts off the lead wire, the main shaft drives the second driving rod to be close to the first cutter. At this time, the first cutter cuts off the lead wire under the action of the second driving rod, and the spring on the first cutter is compressed. With the rotation of the main shaft, the second driving rod is away from the first cutter, and the first cutter is away from the flattening block under the elastic action. This setting realizes the cutting work of the cutter piece.
[0013] Optionally, the driving piece comprises a main shaft rotationally connected with the upper side of the base, a plurality of cams fixed to the side wall of the main shaft, and a driving motor for driving the main shaft to rotate, the first driving rod and the second driving rod both abut against the side wall of the cam.
[0014] By adopting the above technical scheme, the cam is connected with the base through the main shaft, and the driving motor is used to drive the main shaft to rotate, so as to drive the cam to rotate. This design makes the whole driving device compact in structure, reduces the space occupation, and improves the overall integration of the equipment.
[0015] Optionally, the base is provided with a threading block, the threading block is located between the wire feeding mechanism and the flattening piece, the threading block is used for threading the lead wire, and the side wall close to the flattening piece of the threading block is also provided with the cutter piece.
[0016] By adopting the above technical scheme, the threading block provides a clear guide path for the lead wire, reduces the possibility of deviation and bending of the lead wire in the mold, and improves the accuracy and stability of the processing.
[0017] Optionally, the wire feeding mechanism comprises a first clamping jaw, a second clamping jaw, a transmission rod slidingly connected to the upper side of the base, and a driving cylinder for driving the transmission rod to reciprocate, the first clamping jaw is fixed to the side wall of the transmission rod, the second clamping jaw is fixed to the upper side of the base, the side wall of the first clamping jaw and the side wall of the second clamping jaw are both provided with a brake piece, and the main shaft controls the opening and closing process of the first clamping jaw and the second clamping jaw through the brake piece.
[0018] By adopting the above technical scheme, the driving cylinder drives the transmission rod to reciprocate, which can quickly drive the first clamping jaw to move, realize quick clamping and releasing of the lead wire, and improve the response speed and efficiency of the wire feeding. The first clamping jaw and the second clamping jaw are connected to the main shaft through the brake piece, which can ensure the stability when clamping the lead wire and reduce the possibility of deviation and falling off of the lead wire during transmission.
[0019] Optionally, a plurality of filling blocks are arranged on the base, and the filling blocks are used to limit the position on the base.
[0020] By adopting the above technical scheme, the filling block can be placed at a specific position on the base as needed, thereby playing a role in positioning other components.
[0021] Optionally, a blanking port is formed in the side wall of the base, and the blanking port is in communication with the position of the base close to the first cutter.
[0022] By adopting the above technical scheme, when the cutter cuts off the finished lead wire, the lead wire slides out of the base through the blanking port, which facilitates the collection work of the staff.
[0023] In summary, the present application has at least one of the following beneficial technical effects:
[0024] 1.

The cutter cuts the upper segment of the lead wire at the same time, which realizes that the length of the flattened steel wire is consistent.
[0025] 2. The staff installs the lead cutting die, first installs a plurality of filling blocks to the side wall of the base, then under the positioning action of the filling block, the staff installs other components, which makes the cutting work stable, reduces the possibility of component deviation caused by equipment shaking, and improves the quality of the output product.
