After the technical scheme is adopted, the utility model has the effects that:

1. because drive through the double track (be two-sided), consequently the drive power is more sufficient, is difficult to appear the condition that the screw drawing of patterns failed.

2. Because the driving force is respectively applied to the two ends, the stress is more balanced, and the situation that one end is damaged due to overlarge stress is not easy to occur.

Detailed Description

It is specifically noted that, in the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise; the meaning of "several" is at least one. All directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative positional relationship between the components, the movement, and the like in a certain posture, and if the certain posture is changed, the directional indicator is changed accordingly.

The technical solution of the present invention is further described by the following examples:

the utility model provides a double-rail reverse-beating main part for a heading machine, which is shown in a combined figure 1 and a figure 2 and comprises the following components: pendulum piece 1, two bracing pieces 2 and two actuating levers 3, the front end of pendulum piece 1 is rotating part 11, and the rear end is the part of beating backwards 12, and the part of beating backwards 12 has the screw hole of beating backwards 121 that extends along upper and lower direction, and two actuating levers 3 are located the left side and the right side of rotating part 11 respectively, are connected through a bracing piece 2 between rotating part 11 and the actuating lever 3, are connected through another bracing piece 2 between rotating part 11 and another actuating lever 3.

As shown in fig. 3, when the dual-rail flip-flop main assembly is installed, the flip screw 1001 is screwed into the flip screw hole 121, the two support rods 2 are respectively inserted into the two support seats 1002, and the two driving rods 3 are respectively connected with the two cams 1003. When the cam 1003 rotates, the double-track reverse driving main part can be driven to integrally rotate, and the reverse driving screw 1001 impacts a sliding rod of the heading machine to realize demolding operation. Therefore, the double-rail inverted main part with the structure has the following advantages:

Specifically, the drive lever 3 has a drive screw hole 31 extending in the left-right direction. When the double track flip main body is mounted, a part of the drive screw 1004 may be screwed into the drive screw hole 31, and the drive nut 1005 may be engaged with another part of the drive screw 1004, thereby preventing the drive lever 3 from being withdrawn from the cam 1003.

Specifically, the side surface of the drive lever 3 has a key groove 32. When the double-track reverse beating main part is installed, one part of the flat key 1006 can be embedded into the key groove 32, the cam 1003 is also provided with a corresponding groove, and the other part of the flat key 1006 is embedded into the groove of the cam 1003, so that the synchronous rotation of the double-track reverse beating main part and the cam 1003 is ensured.

Specifically, the driving rod 3 is in a circular truncated cone shape, and the taper of the driving rod 3 is 2-4 degrees. The drive rod 3 in the shape of a circular truncated cone can serve as a guide and can be more easily inserted into the cam 1003 when installed. Preferably, the taper of the drive rod 3 is 3 °.

Specifically, the front end of the rotating portion 11 has an arc notch 111, the radius R1 at the upper end of the arc notch 111 is 38-40 mm, and the radius R2 at the lower end is 33-35 mm. The arc notch 111 belongs to a space-avoiding part, and avoids interference with a center pillar of the heading machine. In the embodiment, the radius of the upper end of the arc-shaped notch 111 is set to be smaller than that of the lower end according to the rotation amplitude of the double-rail inverted main component.

Specifically, two side surfaces 122 of the inverted portion 12 are both arc surfaces, and the radius R3 of the side surfaces 122 is 44-46 mm; the rear surface 113 of the inverted portion 12 is a semicircular arc surface, and the radius R4 of the rear surface 113 is 12-13 mm. Providing both the side surfaces 122 and the rear surface 113 of the flip portion 12 as arc surfaces can provide the flip portion 12 with higher compressive strength and can reduce the possibility of damage thereof due to collision.
