SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a door secondary die mould frock which is reasonable in structure, safe and reliable in action.

The utility model discloses a following technical scheme realizes: door secondary die mould frock, include the frame and be equipped with a plurality of rollers in the frame, the both ends of roller are equipped with the back shaft, the back shaft passes through the bearing and connects in the frame, the below of frame is equipped with roller stop device, roller stop device includes the layer board and is equipped with a plurality of blocks that block on the layer board, block that block is located the below of roller and with the roller one-to-one, the below of layer board still is equipped with the cylinder, the cylinder drive the layer board drives block that block is the straight reciprocating motion of vertical direction.

And a groove is formed in the middle of the clamping block and towards one side of the roller.

And a rubber pad is arranged in the groove.

The clamping block is characterized in that an air bag is arranged in the groove, the lower portion of the air bag is fixedly connected with the inner wall of the groove, an air pipe is arranged in the clamping block, one end of the air pipe is communicated with the air bag, the other end of the air pipe extends to the outside of the clamping block, and a differential pressure valve is arranged on the air pipe.

The supporting legs of the rack are also provided with a pair of vertical sliding grooves, sliding blocks are arranged at two ends of the supporting plate, and the sliding blocks are arranged in the sliding grooves and slide in the sliding grooves.

Compared with the prior art, when the clamping device is used, the air cylinder is lifted, the supporting plate is lifted to move upwards, and thus the clamping block is lifted simultaneously along with the supporting plate and collides with the roller from the lower part, so that the roller is clamped quickly; the roller clamping device has the advantages that the grooves are formed in the clamping stop blocks, the rubber pads or air bags are further arranged in the grooves, so that the friction force of the roller is improved, the clamping stop effect is effective and reliable, the structure is reasonable, and the potential safety hazard caused by the fact that emergency stop cannot be performed is effectively avoided.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of the structure of the middle stop block of the present invention;

in the figure: 1. a frame; 2. a roller; 20. a support shaft; 3. a support plate; 4. a clamping block; 40. a groove; 5. a cylinder; 6. an air bag; 7. an air tube; 8. a chute; 9. a slide block.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-2, a vehicle door secondary profiling tool comprises a frame 1 and a plurality of rollers 2 arranged on the frame 1, wherein supporting shafts 20 are arranged at two ends of each roller 2, the supporting shafts 20 are connected to the frame 1 through bearings, a roller 2 clamping device is arranged below the frame 1, the roller 2 clamping device comprises a supporting plate 3 and a plurality of clamping blocks 4 arranged on the supporting plate 3, the clamping blocks 4 are located below the rollers 2 and correspond to the rollers 2 one to one, a cylinder 5 is further arranged below the supporting plate 3, and the cylinder 5 drives the supporting plate 3 to drive the clamping blocks 4 to do linear reciprocating motion in the vertical direction. When emergency braking is needed, a switch for controlling the air cylinder 5 is started, so that the air cylinder 5 is quickly lifted, the supporting plate 3 is lifted to move upwards, the clamping and stopping block 4 is lifted simultaneously along with the supporting plate 3 and props against the roller 2 from the lower part, and the roller 2 is quickly clamped and stopped; further, the up end that blocks 4 is equipped with the supporting shoe that a pair of rubber was made symmetrically, when blocking 4 conflict roller 2, the top of supporting shoe and roller 2's top parallel and level, like this, the supporting shoe constitutes a plane with roller 2 is whole, increased and treat the frictional force between the die mould door, avoided treating die mould door still can remove because of inertia after roller 2 stops, rational in infrastructure, effectively avoided because of the potential safety hazard that can't the emergency stop brought.

A groove 40 is arranged at the middle part of the clamping block 4 and at one side facing the roller 2. The inner arc surface of the groove 40 is matched with the outer arc surface of the roller 2, so that the contact area between the clamping block 4 and the roller 2 is increased, the friction force is increased, and the reliability of emergency braking is ensured.

A rubber pad is arranged in the groove 40. The friction force is further increased by arranging the rubber pad.

Be equipped with gasbag 6 in the recess 40, the lower part of gasbag 6 with the inner wall fixed connection of recess 40, it is equipped with trachea 7 in the piece 4 to block, the one end intercommunication gasbag 6 of trachea 7, the other end extend to block 4 outsides to block, be equipped with the differential pressure valve on the trachea 7. In the process that the clamping block 4 rises, the air bag 6 firstly contacts with the roller 2 and continues to rise, the roller 2 can compress the air bag 6, after a certain pressure is reached, the differential valve is opened, the gas in the air bag 6 is exhausted, the air bag 6 is compressed between the groove 40 and the roller 2, in the process that the air bag 6 exhausts, the buffer between the clamping block 4 and the roller 2 is realized, the damage to the clamping block 4 or the roller 2 caused by the direct contact of the clamping block 4 and the rotating roller 2 is avoided, and the durability of the clamping device of the roller 2 is improved; further, after the air bag 6 is completely compressed, the friction force between the air bag and the roller 2 can be increased, so that the roller 2 can be stopped and rotated more quickly.

Still be equipped with a pair of vertical spout 8 on the landing leg of frame 1, the both ends of layer board 3 are equipped with slider 9, slider 9 is located in the spout 8, and slide in the spout 8. Set up spout 8 and slider 9 for the rising and the decline of layer board 3 are more smooth and easy, have avoided at the in-process of the quick jacking of cylinder 5, and because of layer board 3 moves not smoothly, and lead to roller 2's the card to end failure even layer board 3's damage, have improved roller 2 card to end the reliability of device.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
