Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of ladder manufacturing equipment, in particular to a one-time punching and forming machine for a front frame of a steel tube ladder with a magnetic attraction structure. Background Art
[0002] The steel tube ladder comprises a front frame and a rear frame hinged to the front frame, and the front frame and the rear frame are transversely fixedly connected with foot rods. Therefore, it is necessary to punch the foot rod connecting holes and the hinge holes on the front frame and the rear frame of the steel tube ladder. For the punching of the front frame, the existing production method is: first punch the hinge holes, and then punch the foot rod connecting holes. This operation is troublesome and inefficient. In addition, there are also some semi-automatic punching equipment on the market. These equipments have a single fixing structure for the steel tube ladder when punching, and the fixing strength is insufficient. It is easy to cause deviation during punching, resulting in large errors, affecting the subsequent assembly of the ladder and increasing the scrap rate. Utility Model Content
[0003] In view of the problems mentioned in the background technology, the purpose of the utility model is to provide a steel pipe ladder fixing structure of a steel pipe ladder front frame punching machine to solve the problems existing in the above-mentioned background technology.
[0004] The above technical objectives of the utility model are achieved through the following technical solutions:
[0005] A steel pipe ladder fixing structure of a steel pipe ladder front frame punching machine includes a frame, and two mounting tables are arranged on the frame. The two mounting tables are arranged in parallel, and the two mounting tables can be far away from or close to each other. A plurality of front frame upper and lower limit assemblies are arranged on the two mounting tables. When punching, the front frame upper and lower limit assemblies are used to limit the front frame body up and down; it also includes front frame front and rear fixing assemblies. When punching, the front frame front and rear limit assemblies are used to limit the front frame body front and back.
[0006] Preferably, both ends of the mounting table are connected to the frame via a first slider rail assembly.
[0007] Preferably, the upper and lower limit assembly of the front frame includes a first cylinder fixed on the mounting table, a linkage block is arranged on the piston rod of the first cylinder, a pressure rod is connected to the outer end of the linkage block, and a pressure block is arranged on the end of the pressure rod.
[0008] Preferably, an extension frame is horizontally arranged on the front end of the frame, a movable plate is arranged on the extension frame, the front and rear fixing components of the front frame include a connecting plate arranged on the movable frame, a blocking portion is arranged on the outer end of the connecting plate, the front end of the front frame is placed on the connecting plate and its top end abuts against the blocking portion, a second cylinder is arranged on the end of the mounting table, an abutting column is connected to the piston rod of the second cylinder, and when fixed, it abuts against the end of the front frame through the abutting column.
[0009] Preferably, a plurality of limit holders arranged in a straight line are also provided on the installation table to achieve left and right limit of the ladder steel pipe.
[0010] In summary, the utility model mainly has the following beneficial effects:
[0011] The present application provides a front frame body for upper and lower limit positioning, a front frame front and rear fixing assembly, and a limit clamping seat to fix the front frame up and down, front and back, and left and right during punching, thereby improving the stability during punching, reducing the error generated during punching, and improving the product yield.
