Description

Door plant water is cut overhead preflex compression fittings

Technical Field

The utility model relates to a door plant water is cut overhead preflex compression fittings specifically is the door plant water is cut the process of borduring part A face resilience, the water technical field who cuts.

Background

The water cutting position of the door plate is always a place where the edge covering die is difficult to debug and the size of a part is difficult to control, and the defects that the convex die is not attached to the outer plate surface after pre-bending, the water cutting edge curling, the R angle is not smooth after pressing and the like often occur. Because the door plant water is cut the position and does not have the laminating of inner panel spare and support, and can't arrange the pressure material piece, just control the water and cut a part bordure face in less angular range, no matter be present commonly used rotatory wedge of borduring or side push away slider mechanism can't fine solution this problem, still need adjust clearance and pre-bending sword contact material state repeatedly to satisfy assembly part requirement, require too high to mould precision, stability. The debugging period is prolonged, the cost is increased, and the state of the part is unstable.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the difficult loaded down with trivial details problem of above-mentioned production debugging, provide a door plant water and cut overhead preflex compression fittings. When simplifying the mould structure, can be better when solving the preflex to the bad various defect problems that bring of part atress, reduce manufacturing and debugging cost when solving the part quality problem, increase mould stability.

The utility model discloses a concrete technical scheme is:

a door plate water cutting overhead pre-bending pressing device comprises door plate inner and outer plate parts, an upper die body, a lower moulding bed, a moulding bed guide plate, a pressing cutter, a pre-bending sliding block, an upper die guide plate, a spring and a limiting pressing block; the pre-bending sliding block is arranged in the upper die body, a guide plate for back and forth movement is configured on the bottom surface, and a counter bore is processed in the pre-bending sliding block for placing a spring; fixing a limiting pressing block on an upper die body at the rear side of the pre-bending sliding block by using a screw, and sealing the contact between the pre-bending sliding block and the spring to provide necessary limiting and return force for the pre-bending sliding block; because the front part of the pre-bending slide block is contacted with the guide plate of the forming die to move, the front part needs to be finely ground; and the pressing knife is locked on the upper die body by using a screw, and the pressing and edge covering are carried out when the die is closed to the bottom.

When the assembly part processing device works, the assembly part coated with the glue is placed in the lower tire mold, and the upper mold body moves downwards; firstly, a pre-bending sliding block is contacted with a flanging surface of an outer plate for pre-bending, the sliding block is contacted with a mould guide plate when the pre-bending sliding block is pre-bent to a set angle, an upper mould body continuously moves downwards, the pre-bending sliding block is pressed and retreated, a pressing cutter fixed on the upper mould body starts to be contacted with the pre-bending surface, the pressing cutter finishes edge covering and pressing when the upper mould body continuously moves downwards, and the mould is closed to the bottom at the moment; and then the upper die body starts to move upwards, the pre-bending sliding block moves forwards under the return force provided by an internal spring, and all parts return to the initial state and then are produced by the next punching time.

The utility model has the advantages that: because the pre-bending slide block is fixed on the upper die body, the pre-bending slide block can pre-bend parts at a more reasonable angle, and various defects caused by the fact that a reasonable pushing angle cannot be found when a pre-bending cutter is used for lower dies are overcome. The pre-bending sliding block is designed on the upper die body, so that the structure is simple, meanwhile, the pre-bending propelling acting force is in an R angle area, the defects that the outer plate surface is not attached with a convex die, the water cutting curling edge is formed, the R angle is not smooth after pressing and the like can not be caused to the outer plate part, and only the contact surface of the pre-bending sliding block and the part needs to be changed if the angle of the pre-bending surface needs to be adjusted in the later period. Utilize the utility model discloses can reduce the various problems of borduring that the preflex brought, sparingly make and debug the cost, improve work efficiency.

Detailed Description

The present invention will be further described with reference to the accompanying drawings for more clearly illustrating the technical solutions.

Fig. 1 is a sectional view of a method for laminating a door panel by water cutting and pre-bending, and fig. 2 to 4 are flow charts of laminating operation of the method, which respectively comprise three steps of initial state, pre-bending completion and laminating completion. In the process of pressing down the upper die body 10, the pre-bending sliding block 7 firstly contacts the outer plate part 1 to pre-bend the opposite side, and when the upper die body 10 is pressed down to a certain degree, the pre-bending finishing sliding block 7 contacts the guide plate 2 of the forming die. Due to the limitation of a limiting press block 9 at the rear side of the pre-bending slide block 7, when the upper die body 10 continues to descend, a spring 8 in the pre-bending slide block 7 is compressed, and the pre-bending slide block 7 moves backwards along the tire die guide plate 2. The upper die body 10 continues to move downwards and is locked on the pressing cutter 5 to start to contact the pre-bending surface, and after the upper die body 10 moves downwards to a set value, the pressing cutter 5 completes edge covering.

After the mold is closed to the bottom, the machine tool gradually opens the upper mold body 10 to start to move upwards, and the pressing cutter 5, the upper mold body guide plate 6, the pre-bending slide block 7, the spring 8 and the limiting press block 9 which are fixed on the upper mold body 10 move upwards together. After the pre-bending sliding block 7 is not limited by the closing height of the upper die body 10, the spring 8 in the pre-bending sliding block provides a force source to drive the pre-bending sliding block 7 to move forwards under the limitation of the limiting pressing block 9. The upper mold body 10 continues to ascend back to the initial state. The above-mentioned processes are repeated so as to implement mass production.
