Description

Technical Field

[0001] The utility model relates to a processing device for a safety belt steel wire rope, in particular to a pre-pressing device for a safety steel wire rope. Background Art

[0002] The safety belt wire rope includes a bracket and a steel wire riveted to the bracket. In the prior art, the riveting between the bracket and the steel wire is usually achieved manually, and the efficiency of manual riveting is extremely low. Later, some fast riveting equipment gradually appeared, and the processing efficiency of the riveting equipment has indeed been greatly improved. However, this process still requires manual processing of the bracket directly placed on the riveting equipment, and then the steel wire is assembled on the bracket, and then directly pressed. In this process, the product qualification rate is often very low due to inadequate manual assembly, thereby causing a waste of production costs. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a pre-stressing device for a safety steel wire rope which can ensure the accuracy of the riveting position, thereby improving the qualified rate of product production and effectively reducing the production cost of an enterprise.

[0004] In order to solve the above technical problems, the prestressing device of the safety wire rope of the utility model comprises a frame, a load-bearing seat arranged at the lower part of the front side of the frame, a prestressing seat supported by the load-bearing seat, an upper die seat arranged at the upper part of the front side of the frame corresponding to the position of the prestressing seat, and a driving device installed on the frame for driving the upper die seat to move relative to the prestressing seat. The prestressing seat is provided with a placement position for placing the preinstalled wire rope body and the bracket, and the prestressing seat is also provided with a limit block with a limit hole. The upper die seat is provided with a limit rod that can be inserted into the limit hole and a pressing block for pressing the preinstalled wire rope body and the bracket. The prestressing seat is supported by the load-bearing seat and can be pressed by the limit rod and the limit hole. Then, the preinstalled wire rope body and the bracket in the placement position are pressed through the pressing block.

[0005] A pressing arm device for pre-pressing and positioning the pre-installed steel wire rope body and the bracket is arranged beside the pre-pressing seat.

[0006] The pressing arm device includes a seat frame, a pressing block and a cylinder. The pressing block is hinged on the telescopic end of the cylinder. A swing arm is hinged between the seat frame and the pressing block. The swing arm can be swung and pressed on the placement position of the pre-pressing seat by driving the cylinder.

[0007] The press block is provided with a contoured press plate for positioning the bracket.

[0008] The frame is provided with a fixing plate, the lower part of the fixing plate is provided with a lower pressing plate connected by a guide rod, and the pressing block is arranged at the bottom of the lower pressing plate.

[0009] The pre-pressing seat is arranged on a rotating disk with a through hole, and the load-bearing seat can pass through the through hole and press against the bottom of the pre-pressing seat.

[0010] A handle is arranged on the pre-pressing seat.

[0011] The advantages of the utility model are:

[0012] By means of a load-bearing seat arranged at the lower front part of the frame, a pre-pressing seat supported by the load-bearing seat, and an upper die seat arranged at the upper front part of the frame corresponding to the position of the pre-pressing seat, the pre-pressing seat is supported by the load-bearing seat and can be matched with the limiting rod in the limiting hole, and then the pre-installed wire rope body and the bracket in the placement position can be pressed through the pressing block. On the one hand, after the pre-pressing, the subsequent pressing is carried out after the inspection is qualified, thereby ensuring the accuracy of the subsequent pressing and riveting position, ensuring the quality of the pressing, and thus improving the qualified rate of product production. On the other hand, even if unqualified products appear in the pre-pressing process, they can be disassembled and then pre-installed separately, further reducing the product scrap rate. On the other hand, by using the pressure arm device for positioning and the matching of the limiting rod and the limiting hole, the positioning reliability during the pre-pressing process can be guaranteed, further improving the yield rate, thereby effectively reducing the production cost of the enterprise.

[0019] The preloading device for the safety steel wire rope of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] As shown in the figure, the pre-pressing device of the safety wire rope of the utility model comprises a frame 1, a load-bearing seat 2 arranged at the lower part of the front side of the frame, a pre-pressing seat 3 supported by the load-bearing seat, an upper die seat 4 arranged at the upper part of the front side of the frame corresponding to the position of the pre-pressing seat, and a driving device 5 installed on the frame for driving the upper die seat to move relative to the pre-pressing seat. The pre-pressing seat 3 is provided with a placement position 6 for placing the pre-installed wire rope body and the bracket. The pre-pressing seat 3 is also provided with two limit blocks 7 with limit holes. The two limit blocks 7 are placed On both sides of the placement position, the height of the placement position 6 is higher than the height of the limit block. The upper mold base 4 is provided with a limit rod 8 that can be inserted into the limit hole and a press block 9 for press-fitting the pre-installed wire rope body and the bracket. When the upper mold base 4 moves downward, the limit rod 8 can be inserted into the limit hole first to realize the accurate positioning of the pre-pressing seat 3. The pre-pressing seat 3 is supported by the load-bearing seat and can be pressed by the limit rod and the limit hole. Then, the pre-installed wire rope body and the bracket in the placement position are pressed through the press block 9.

[0021] Furthermore, a pressure arm device 10 for pre-pressing and positioning the pre-installed wire rope body and bracket is arranged on the side of the pre-pressing seat 3. The pressure arm device 10 includes a seat frame 11, a pressure block 12 and a cylinder 13. The pressure block 12 is hinged on the telescopic end of the cylinder 13. A swing arm 14 is hinged between the seat frame 11 and the pressure block 12. The pre-installed wire rope body and bracket are placed on the placement position 6 and before the pre-pressing work, the swing arm can be driven by the cylinder 13 to swing and then press the wire rope body and bracket on the placement position 6. The pre-pressing by the pressure arm device 10 can make the pre-assembled wire rope body and bracket accurately limited to the placement position, thereby further improving the accuracy.

[0022] Furthermore, a contoured pressing plate 15 for positioning the bracket may be provided on the front side of the pressing block 9. The contoured pressing plate is adapted to the shape of the pre-installed wire rope body and the bracket, thereby improving the pressing effect.

[0023] Furthermore, the frame 1 is provided with a fixed plate 16, the lower part of the fixed plate is provided with a lower pressing plate 18 connected by a guide rod 17, the pressing block 9 is arranged at the bottom of the lower pressing plate, and the lower pressing plate realizes the pressing operation of the pressing block 9 through the guidance of the guide rod.

[0024] Furthermore, a handle 20 is provided on the pre-stressing seat 3, and the pre-stressing seat 3 is placed on a turntable 19 with a through hole. The load-bearing seat 2 can pass through the through hole and press against the bottom of the pre-stressing seat, so that the turntable can be used to automatically transport the pre-stressing seat 3 pre-assembled with the wire rope body and the bracket, and the load-bearing seat 2 presses against the bottom of the pre-stressing seat through the through hole to avoid the pressure applied to the turntable during the pre-stressing process.

[0025] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
