Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
the utility model provides a novel elevator door plant, as shown in fig. 1-2, slidable mounting is on sill 2, and elevator door plant 1 includes panel plate body 100, and panel plate body 100 is equipped with hem, lower hem, left hem and right hem all around, goes up hem, lower hem and panel plate body 100 and is the integral type structure, and common upper and lower head welded structure intensity obtains greatly improving on the security than on the market, need not anxious head and takes off the risk and fall the well and cause the casualties accident in making the passenger. The middle part of the panel body 100 is provided with a left reinforcing rib and a right reinforcing rib along the vertical direction, and the left reinforcing rib and the right reinforcing rib are uniformly distributed on the panel body 100 to divide the panel body 100 into three parts.
The left reinforcing rib and the right reinforcing rib are tightly attached to the panel body. The bending angle of the visible surface of one side of the left reinforcing rib and the right reinforcing rib is 91-92 degrees, and the bending angle of the visible surface of the other side of the left reinforcing rib and the right reinforcing rib is 271-272 degrees. The bending angle of the reinforcing rib slightly exceeds the right angle, so that the reinforcing rib can be tightly attached to the panel body 100 and cannot be easily separated, the elastic strength of the panel body 100 can be increased, the panel body 100 can bear stronger impact force without generating plastic deformation, welded reinforcing ribs are adopted, the elastic deformation of the panel body 100 after being impacted is smaller, the plastic deformation is generated when a certain value is exceeded, particularly, each welding point is welded point by point, the integral heating of the panel is unbalanced during welding processing, the phenomenon that the panel is not flat is easily generated after the panel is cooled after welding is completed, the abrasion of the sliding block 3 is easily aggravated due to the fact that the panel is not flat, the noise is increased to influence the comfortable sensation, and serious noise even can cause serious consequences such as vexation and blood pressure rise of passengers. This application left strengthening rib, right strengthening rib have not only increased panel intensity and plane degree with panel plate body 100's elasticity laminating design, and the upper and lower both ends of left strengthening rib, right strengthening rib all adopt to insert limit structure and last hem, lower hem fixed connection moreover for the strengthening rib does not produce and rocks and the displacement, need not anxious strengthening rib and panel plate body 100 and throw off production gap and lead to the intensity decline.
In addition, the upper and lower ends of the left and right reinforcing ribs can be fixedly connected with the upper and lower folded edges by screws, and the middle parts of the reinforcing ribs and the right reinforcing ribs are welded and fixed with the panel body 100. The common welding mode that adopts high density is fixed on the strengthening rib market, the thermal production of welding easily leads to strengthening rib and panel to produce huge deformation simultaneously, thereby lead to the door plant plane degree relatively poor, the noise production reduces product life, and this application adopts strengthening rib intermediate position spot welding fixed, the one-shot welding reduces welding density deflection and ignores, and strengthening rib both ends screw fixation mode, can be to carrying out the secondary again with the panel deformation because of the strengthening rib that the welding heat leads to and correct the plane degree of finding back, reduce welding point quantity through the strengthening rib and can improve batch production's efficiency, still the secondary corrects the plane degree and guaranteed product quality again.
As shown in FIG. 3, the left reinforcing rib can also be used as a weight guide, the left reinforcing rib is hollow, and the top of the upper hem is provided with a square opening 114 communicated with the left reinforcing rib. The elevator door panel also includes a weight that fits into the left stiffener from top to bottom through the square opening 114. Through the installation of weight, make left strengthening rib dual-purpose one thing, the existence of weight has increased the quality of door plant to a certain extent and has made the stability reinforcing of door plant.
As shown in fig. 4 to 7, the panel body 100 is divided into three parts by the left and right reinforcing beads; the lower hem is provided with 3 hem grooves which are respectively positioned below the three parts, the hem grooves positioned at two sides are respectively bent downwards to form a slider bracket 107a, the slider bracket 107a is provided with a notch 107a-1 for installing the slider 3, and the hem groove positioned in the middle is bent downwards to form an anti-drop hook 109. The sill 2 is provided with an anti-falling plate 202 downwards along the sliding groove 201, and the anti-falling hook 109 hooks the anti-falling plate 202 to prevent the panel body 100 from being separated from the sill 2, so that the safety is improved. One end of the sliding block 3 is inserted into the sliding block bracket 107a and is clamped into the corresponding flanging groove through the notch 107a-1 and then is fastened; the other end of the sliding block 3 is located between the folding groove and the anti-dropping plate 202, and drives the panel body 100 to slide left and right along the sill 2. Further, the slider 3 is of a structure with a big end at one end and a small round end at the other end, the slider clamping groove 301 is arranged in the middle, the notch 107a-1 is also of a structure with a small upper end and a big lower end, the small round end of the slider penetrates into the upper end of the notch 107a-1 during installation, the slider clamping groove 301 is clamped into the lower end of the notch 107a-1 after installation, and the slider is clamped through interference fit. Because the door is opened and closed leftwards and rightwards, the sliding block 3 cannot fall off upwards, and the door is safe, reliable and convenient to replace.
A production process of a novel elevator door plate comprises the following steps:
1. cutting the plate according to the unfolding size of the door plate to obtain a blank plate;
2. punching and grooving the upper end and the lower end of the blank plate to obtain a substrate;
