Description

Technical Field

[0001] The utility model relates to the technical field of steel purlin production and processing, in particular to a steel purlin forming machine with adjustable hole spacing. Background Art

[0002] Steel purlins are made by hot-rolled plates and cold-bent. They have the advantages of thin walls, light weight, excellent cross-sectional performance and high strength. Common steel purlins include Z-shaped steel purlins and C-shaped steel purlins. Steel purlins are secondary load-bearing components in the roof structure system. They transfer the roof load to the steel frame and are also widely used in steel structure projects such as wall beams.

[0003] At present, in the production process of steel purlins, an integrated forming machine is usually used for the forming process of steel purlins. At the same time, in order to meet different installation requirements, the steel material in the early stage of steel purlin forming usually needs to be pre-treated by punching or grooving. However, the traditional steel purlin forming machine still has certain shortcomings in the punching process, that is, most punching devices usually adopt a fixed configuration, which makes it impossible to flexibly adjust the punching spacing. Purlins of different specifications have different stamping requirements. In order to meet different stamping requirements, it is usually necessary to replace the mold multiple times or use different types of equipment, resulting in certain usage limitations.

A slide groove 211 is arranged on the side wall of the first seat body 21. Multiple groups of connecting rods 4 are slidably arranged in the slide groove 211, and a scale line 212 of matching length is arranged above the corresponding slide groove 211. A pointer 41 and a fastener 42 are arranged at one end of the connecting rod 4, and the other end is connected to the head end of the corresponding punch head 23 slidably arranged on the first seat body 21. The tail end of the punch head 23 is placed in the matching groove 221 opened on the second seat body 22.

[0019] Specifically in the present embodiment, the steel purlin 100 can be conveyed along the base 3 of the stamping assembly on the machine body through a conveying mechanism with a conventional structure on a conventional machine body for forming the steel purlin 100. The stamping assembly can perform a stamping process on a specific stamping position on the steel purlin 100. Specifically, the cylinder 11 on the fixed frame 1 works to push the stamping seat 2 to move downward.

The first seat body 21 can continue to move downward along the second seat body 22 below under the push of the cylinder 11 through the multiple groups of sliding rods 24 slidably arranged thereon and the adaptor compression springs 241 sleeved on the outer side, while driving the sliding device 24 on the first seat body 21. The multiple groups of punching heads 23 are moved downward, and the tail end of the punching head 23 moves downward along the adapting groove 221 provided on the second seat body 22, and contacts the surface of the steel purlin 100 on the base 3. At the same time, under the push of the cylinder 11, the punching head 23 continues to move downward and penetrates the base 3 of the corresponding groove 221 structure, thereby realizing the stamping process of adapting the shape of the punching head 23 to the corresponding stamping position of the steel purlin 100 on the base 3. In the early stage of stamping, the punching heads 23 slidably provided on the first seat body 21 can be adapted in corresponding numbers according to specific usage requirements, and are connected with the connecting rods 4 slidably provided in the slide groove 211 of the first seat body 21 connected to the head end of the corresponding punching head 23. For details, please refer to Figure 2 As shown, by toggling one end of the connecting rod 4 or the punching head 23 having the pointer 41 and the fastener 42, the connecting rod 4 drives the punching head 23 to move to different positions in the slide groove 211 of the first seat body 21. At the same time, during the movement of the punching head 23, the pointer 41 provided at one end of the connecting rod 4 can correspond to the specific position of the scale line 212 on the side wall of the first seat body 21, and the spacing between the multiple groups of punching heads 23 can be adjusted according to the specific punching requirements. In addition, when the specific punching position corresponding to each group of punching heads 23 is adjusted, the punching head 23 can be pressed by rotating the pointer 41 as shown in FIG. Figure 3The fastener 42 provided at one end of the connecting rod 4 is used to adjust and fasten the connecting rod 4 and its punch head 23 at the corresponding position of the first seat body 21 to realize the stamping process between different hole spacings. Compared with the stamping device on the traditional steel purlin 100 forming machine, the specific structural setting of this stamping assembly can facilitate the adjustment of the spacing between multiple groups of punch heads 23 according to different stamping requirements, and at the same time cooperate with the scale line 212 provided on the first seat body 21 and the fastener provided at one end of the connecting rod 4 connected to the head end of the punch head 23. 42, can further improve the positioning accuracy of multiple groups of punch heads 23, while reducing unnecessary influence on the punching effect caused by the shaking or deviation of the punch heads 23. In addition, the multiple groups of punch heads 23 slidably arranged on the first seat body 21 can be adjusted on the first seat body 21 according to the seat structure adapted to the first seat body 21, and the spacing between adjacent punch heads 23 can also be adjusted with equal spacing or non-equal spacing to meet the different stamping requirements of purlins of different specifications, thereby improving flexibility and convenience during use.

[0020] See also Figure 4 The first seat body 21 adopts a symmetrical structure, and the slide grooves 211, scale lines 212 and multiple groups of connecting rods 4 in the slide grooves 211 on its side walls are adapted to the seat structure of the first seat body 21 and are distributed on both sides of the seat body, and the multiple groups of punching heads 23 slidably arranged thereon are adapted to the seat structure of the first seat body 21 and are distributed in double rows. The grooves 221 provided on the second seat body 22 below the first seat body 21 are adapted to have two groups of adapting seat structures of the first seat body 21 with a symmetrical structure, cooperate with the slide grooves 211, scale lines 212 and multiple groups of connecting rods 4 distributed on the side walls on both sides of the seat body, and can respectively adjust the multiple groups of punching heads 23 distributed in double rows on the first seat body 21 to corresponding positions, and can realize double-row punching and staggered punching, so that this type of stamping seat 2 can meet different stamping requirements and improve adaptability and flexibility in use.
