Three-dimensional storage device for cold-drawing machine

Abstract

This utility model relates to a three-dimensional material storage device for a cold drawing machine. A material storage rack is located behind the cold drawing bed of the cold drawing machine, and a tube pusher rack is located above the cold drawing bed. The upper end of the material storage rack has a storage plate for stacking metal tubes, and the upper end of the tube pusher rack has a pusher frame inclined towards the cold drawing die. The storage plate is inclined towards the pusher frame, causing the metal tubes to slide onto the pusher frame and be arranged at intervals. A tube pusher trolley is installed on the pusher frame located on one side of the hydraulic cylinder seat. When the tube pusher trolley moves along the pusher frame towards the cold drawing die, it pushes the metal tubes arranged on the pusher frame into the mandrel of the cold drawing machine. This utility model sets a tube pusher rack directly above the cold drawing bed to arrange the metal tubes sliding from the storage rack. The movement of the tube pusher trolley pushes the metal tubes to be cold drawn onto the mandrel. This integrates the tube-piercing station of the conventional cold drawing process between the material storage station and the cold drawing station, thereby greatly shortening the overall length of the cold drawing production line.

Description

Technical Field

[0001] This utility model relates to the field of cold drawing machine technology, and in particular to a three-dimensional material storage device for cold drawing machines. Background Technology

[0002] Cold drawing is a metal cold treatment method that involves clamping the end of a metal tube with a clamping trolley mounted on the cold drawing machine body, and then pulling it out under the reverse traction of the clamping trolley, thereby extending the length of the metal tube.

[0003] In the traditional process route, the layout of each station of the cold drawing machine is as follows: the cold drawing station is set at the front end of the tube threading station, the mandrel unit is set at the rear end of the tube threading station, and the material storage station is set above the tube threading station. After the metal tubes on the material storage station fall into the tube threading station and are arranged, the mandrel unit inserts the mandrel from the rear end of the metal tube, and finally the cold drawing station performs cold drawing processing on the metal tube.

[0004] Obviously, this horizontal tube-threading layout requires a tube-threading station between the core rod unit and the cold drawing station, which inevitably results in a longer overall length of the cold drawing production line and a larger footprint. Therefore, it is necessary to provide a compact storage device with a small footprint. Summary of the Invention

[0005] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a three-dimensional material storage device for cold drawing machines, so as to solve the problem that the existing cold drawing production line has a long layout length and occupies a large area.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a three-dimensional material storage device for a cold drawing machine. The cold drawing machine has a cold drawing bed, a cold drawing die holder is installed at the left end of the cold drawing bed, and a cylinder seat for installing a cold drawing cylinder is provided at the right end of the cold drawing bed. A material storage rack is provided close to the rear side of the cold drawing bed, and a tube pusher rack is provided directly above the cold drawing bed. The upper end of the material storage rack has a material storage plate for stacking metal tubes, and the upper end of the tube pusher rack has a pusher frame. The material storage plate is inclined towards the pusher frame so that the metal tubes slide down onto the pusher frame and are arranged at intervals. The pusher frame is inclined towards the cold drawing die holder. A tube pusher trolley is installed on the pusher frame located on the side of the cylinder seat. When the tube pusher trolley moves along the pusher frame towards the cold drawing die holder, it pushes the metal tubes arranged on the pusher frame into the cold drawing machine core rod located on the left side of the cold drawing die holder.

[0007] Specifically, the left end of the pusher frame is fixed on the cold drawing die base and the right end is fixed on the cylinder base. The pusher frame includes two long crossbeams arranged at a distance from each other. Short crossbeams are fixed to the left and right ends of the long crossbeams respectively. A receiving plate for arranging metal tubes is provided between the bottom of the long crossbeams. The pusher trolley is rolled between the upper surfaces of the two long crossbeams.

[0008] Furthermore, the tube pusher includes a vehicle body, a push plate fixed to the left end face of the vehicle body, rollers that roll in cooperation with the upper end face of the long crossbeam on the outer sides of the front and rear corners of the vehicle body, a left traction plate fixed to the bottom surfaces of the front and rear sides of the left end of the vehicle body, a right traction plate fixed to the bottom surfaces of the front and rear sides of the right end of the vehicle body, and a traction mechanism that connects to the left traction plate and the right traction plate and pulls the tube pusher to move is installed on the tube pusher frame.

[0009] Specifically, the traction mechanism includes a hydraulic motor, a drive shaft, and a driven shaft. The hydraulic motor is mounted on the rear right side of the push tube rack. The drive shaft is rotatably mounted on the right end of the push tube rack, and the driven shaft is rotatably mounted on the left end of the push tube rack. The hydraulic motor and the rear end of the drive shaft are connected by gear meshing. Drive sprockets are mounted at the front and rear ends of the drive shaft, and driven sprockets are mounted at the front and rear ends of the driven shaft. A chain is connected between the drive sprockets and the driven sprockets. The left traction plate and the right traction plate are connected to the chain.

[0010] Preferably, the inner side of the push tube rack is provided with chain guide rails arranged vertically, and the chain slides along the chain guide rails.

[0011] Furthermore, to better guide the movement of the tube pusher, guide wheels that roll in cooperation with the inner side of the long crossbeam are respectively installed on the bottom surfaces of the left and right traction plates.

[0012] The beneficial effects of this utility model are as follows: This utility model sets up a tube pusher rack directly above the cold drawing bed to arrange the metal tubes that slide down from the storage rack. By moving the tube pusher, the metal tubes to be cold drawn are pushed into the mandrel. This is equivalent to integrating the tube threading station of the conventional cold drawing process between the storage station and the cold drawing station, thereby greatly shortening the overall length of the cold drawing production line and reducing the area occupied.
