Abstract

A counterweight-balancing forming machine is characterized in a counterweight balancing device which is disposed on a crank shaft set directly and situated at a place opposite to a sliding unit to thereby simplify an entire structure and save a space for placing the counterweight-balancing forming machine. Meanwhile, the crank shaft set can carry out movements of the counterweight balancing device and the sliding unit to allow the counterweight balancing device and the sliding unit to reciprocate toward an opposite direction to thereby balance the inertia force generated by the movement of the sliding unit effectively. Further, the power of the counterweight balancing device can be transmitted directly so as to reduce the wear caused by unnecessary power transmission paths.

Description

Forming machine with counterweight adjustment

The present invention relates to a counterweight balance structure, in particular to a molding machine with counterweight adjustment for a molding machine.

Check, the screw forming machine is generally used in the manufacture of screws, which uses a reciprocating device similar to pushing the wheels of a steam train to operate, that is, a crank arm and or a crank pin are provided on the crankshaft, and the crank arm and the crank pin are connected. The shaft center and the crankshaft center are radially displaced, and at the same time, the precise coordination between the crankshaft pin and the connecting rod mechanism is used, and the multiple processing and forging operations of the traditional process are all integrated into one forging die for processing, so that the crankshaft rotates when the crankshaft rotates. , which is linked with the link mechanism to push the forging die to reciprocate, so that the forging die can be further pushed to quickly complete the processing of the screw, so as to improve the problem that the traditional forging process is too labor-consuming and time-consuming. , the screw forming machine has become one of the indispensable equipment in screw manufacturing.

However, when the screw forming machine performs reciprocating motion to push the forging die to process the screw, it utilizes the impact force generated by the reciprocating motion to enable the forging die to smoothly forge blanks; however, in view of the screw forming The inertial force generated during the operation of the machine is very large, so that the screw forming machine is easily affected by the reaction force during operation, which causes the screw forming machine to vibrate, which not only causes the internal instability and wear of the screw forming machine, but also affects the screw forming machine. The processing accuracy of the screw forming machine, in addition, the components of the current common screw forming machine are too complicated, and the volume is also relatively large, which makes the overall operation too complicated and laborious, and at the same time takes up too much installation space, which needs to be improved.

Therefore, the purpose of the present invention is to provide a molding machine with counterweight adjustment, which not only has a simple structure, but also can transmit the force transmission process of the counterweight adjustment device more directly, so as to reduce the wear caused by unnecessary power transmission paths. .

Therefore, the forming machine with counterweight adjustment of the present invention includes a base, a crankshaft set on the base body, a crank connecting rod set on the crankshaft set, and a sliding seat set on the crank connecting rod, and a counterweight adjustment device fixed on the crankshaft group and arranged in the opposite direction to the sliding seat; wherein, the crankshaft group has a crankshaft pin, two crankshaft arms respectively arranged on both sides of the crankshaft pin, and The crank arms extend outward and are pivoted on the main journal on the base body, and a positioning block is arranged between each crank arm and each main journal, and the positioning blocks are different from the crank arms and the counterweight adjusting device has two linking pieces respectively fixed on the positioning blocks, and a buffer piece arranged at the other end of the linking piece and arranged in the opposite direction to the sliding seat; so that the When the molding machine is in operation, the inertial force generated when the sliding seat is moved can be offset by the counterweight adjusting device, which not only has a simple structure, but also greatly reduces the overall installation space, and at the same time, the force transmission process of the counterweight adjusting device can be more directly transmitted. , so as to effectively reduce the wear and tear of unnecessary power transmission paths.

The foregoing and other technical contents, features and effects of the present invention will be clearly understood in the following detailed description of the preferred embodiments with reference to the drawings.

The main journals 323 are eccentrically arranged on the crank arms 322, and two positioning blocks 324 are respectively arranged between each main journal 323 and its corresponding crank arm 322, and the positioning blocks 324 and the crank arms 322 are in different directions. Displacement arrangement, that is, the positioning blocks 324 are arranged offset from the axis of the crank arms 322, and the main journals 323 are offset from the axis of the positioning blocks 324. In addition, the counterweight adjustment device 35 has two A link member 351 sleeved on the positioning blocks 324 and a buffer member 352 connected to the link member 351 and arranged in the opposite direction to the sliding seat 34 are provided.

Referring to FIGS. 3 and 5 , when the molding machine 3 is in use, the main journal 323 provides a stable torque, and at the same time, the positioning blocks 324 and the crank arms 322 are dislocated in opposite directions, so that the main shaft During the transmission process of the neck 323 , the sliding seat 34 is driven by the crankpin 321 to generate displacement, and the buffer member 352 is driven by the positioning blocks 324 through the linking members 351 to generate a movement in the opposite direction to the sliding seat 34 . Displacement, that is, as shown in FIG. 5, when the sliding seat 34 is displaced in the X-axis direction, the buffer member 352 is displaced in the Y-axis direction, so that the inertial force generated by the displacement of the sliding seat 34 in the X-axis direction can be reduced. The inertial forces generated by the displacement of the buffer member 352 in the Y-axis direction are mutually eliminated.

Referring to FIGS. 4 and 6 , when the sliding seat 34 is driven by the crank pin 321 to move in the Y-axis direction, the buffer member 352 is linked by the positioning members 324 to move in the X-axis direction, so that The inertial force generated by the displacement of the sliding seat 34 in the Y-axis direction can be mutually reduced by the inertial force generated by the displacement of the buffer member 352 in the X-axis direction, so that the sliding seat 34 and the buffer member can be mutually reduced. 352 performs reciprocating motion, and at the same time, the forming machine 3 with counterweight adjustment will not produce excessive shaking during the operation process. In addition, the positioning blocks 324 are arranged between the main journals 323 and the crank arms 322. so as to make the overall structure of the molding machine 3 with counterweight adjustment more compact, while reducing the overall installation space, and the force transmission process of the counterweight adjustment device 35 can be more directly conducted to reduce unnecessary power transmission paths. In addition, the support seat 36 can provide sufficient supporting force for the buffer member 351 , which is more conducive to maintaining the balance of the weight adjusting device 35 .

To sum up the above, the present invention has a forming machine for adjusting the weight, which is arranged between the crankshaft arms and the main journals through the positioning blocks, so that the weight adjusting device is directly disposed on the positioning blocks, Further, the buffer member and the sliding seat are driven to reciprocate in opposite directions by the linking members, which not only has a simple structure, but also has a compact overall structure, which greatly reduces the overall installation space.
