Description

Technical Field

[0001] The utility model relates to the technical field of stretching dies, and more specifically to a double-station stretching die. Background Art

[0002] Drawing dies are specialized tools used to process bulk materials into desired parts. They are widely used in the stamping industry, such as in the manufacture of common products like cups and motor housings. Stainless steel drawing dies are widely used in various fields, including automotive, aviation, shipbuilding, and chemical industries.

[0003] When stretching stainless steel workpieces, existing stretching dies have a single processing station structure, which can only produce and process a single workpiece at a time. This results in low processing efficiency, and most of the unloading process is done manually, which is unsafe. In view of this, we propose a dual-station stretching die. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet practical needs, and provide a double-station stretching die to solve the current technical problems of manual operation, single-station production, low efficiency and low safety.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a double-station stretching mold, comprising a fixed seat, a stretching cylinder and a stainless steel sheet, a first side plate and a second side plate are fixed to the outer side of the fixed seat, a material receiving box is installed on the upper end of the second side plate, and a movable platform is slidably installed on the upper end surface of the first side plate through a guide rail, an outer mold cylinder and a hydraulic rod are provided on the upper end of the movable platform, an adjustment mechanism is provided on the inner end of the movable platform, a turntable is rotatably installed on the upper end surface of the fixed seat, the stretching cylinder is fixed on the turntable through a bracket, inner mold columns are slidably installed in the openings at both ends of the stretching cylinder, and the stainless steel sheet is located between the outer mold cylinder and the inner mold column.

[0006] When the utility model is used, an external power supply is connected, and the operator starts the device through an external control device, puts the stainless steel sheet between the outer mold cylinder and the inner mold column, starts the movable guide rail on the first side plate to drive the movable table to move, and the movable table drives the outer mold cylinder to move toward the stainless steel sheet, and squeezes the stainless steel sheet through the outer mold cylinder to make it close to the inner mold column. The stainless steel sheet is stretched by stamping so that the stainless steel sheet is processed into a cylindrical shape. After the processing is completed, demoulding is performed. During the demoulding process, the hydraulic rod is started to push out the stainless steel part inside the outer mold cylinder so that the stainless steel part is sleeved on the outer side of the inner mold column. After the demoulding is completed, the built-in motor of the fixed seat is started to drive the turntable to rotate. The turntable rotates ninety degrees so that the inner mold column corresponds to the material receiving box. Then start the bidirectional screw to connect the motor to drive it to rotate, and the bidirectional screw thread drives the sliding end of the inner mold column to shrink it into the stretching cylinder. During the shrinkage process, the stainless steel parts outside the inner mold column fall into the receiving box. The device is designed with a double-station structure at both ends, which can perform synchronous operations and improve the processing efficiency. At the same time, the automatic unloading structure design reduces the difficulty of operation and ensures processing safety. When loading, it is adjusted according to the diameter of the stainless steel sheet, and the electric telescopic rod on the upper side of the adjustment frame is started. The electric telescopic rod drives the sliding end of the limit frame to rise and fall. The limit frame is designed in a C shape. When loading, the stainless steel sheet is clamped between the limit frames so that the center of the stainless steel sheet corresponds to the inner mold column to ensure the quality of processing.

[0007] Preferably, two of the first side panels and the second side panels are provided, and the first side panels and the second side panels are symmetrically distributed in a cross shape.

[0008] Preferably, the hydraulic rod is installed at the rear end of the outer mold cylinder, and the outer rod of the hydraulic rod is plug-connected and installed at the inner rear side of the outer mold cylinder.

[0009] Preferably, the adjustment mechanism consists of a limiting frame and an adjustment frame, the adjustment frame is fixed to the inner end of the movable platform, and the limiting frame is slidably mounted on the adjustment frame.

[0010] Preferably, the limiting frame is designed to be C-shaped, and both ends of the limiting frame are slidably installed in the corresponding adjustment frame.

[0011] Preferably, the lower side of the stainless steel sheet is clamped between the limiting frames.

[0012] Preferably, side cylinders are embedded and installed on both sides of the stretching cylinder, and bidirectional screw rods are rotatably installed in the side cylinders.

[0013] Preferably, the sliding end of the inner mold column is connected to the inside of the side tube, and the bidirectional screw thread passes through the sliding end of the inner mold column.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model designs a turntable, and puts the stainless steel sheet between the outer mold cylinder and the inner mold column, and starts the movable guide rail on the first side plate to drive the movable table to move. The movable table drives the outer mold cylinder to move toward the stainless steel sheet, and squeezes the stainless steel sheet through the outer mold cylinder to make it close to the inner mold column. The stainless steel sheet is stretched by stamping, so that the stainless steel sheet is processed into a cylindrical shape. After the processing is completed, it is demoulded. During the demoulding process, the hydraulic rod is started to push out the stainless steel part inside the outer mold cylinder so that the stainless steel part is sleeved on the outside of the inner mold column. After the demoulding is completed, the built-in motor of the fixed seat is started to drive the turntable to rotate. The turntable rotates 90 degrees to make the inner mold column correspond to the material receiving box, and then the two-way screw is started to connect the motor to drive it to rotate. The two-way screw thread drives the sliding end of the inner mold column to shrink it into the stretching cylinder. During the shrinkage process, the stainless steel part outside the inner mold column falls into the material receiving box. The device can perform synchronous operation through the double-station structure design at both ends, thereby improving the processing efficiency. At the same time, the automatic unloading structure design reduces the operation difficulty and ensures the processing safety.

[0016] 2. The utility model also designs an adjustment mechanism. When loading, it is adjusted according to the diameter of the stainless steel sheet. The electric telescopic rod on the upper side of the adjustment frame is started. The electric telescopic rod drives the sliding end of the limit frame to rise and fall. The limit frame is designed in a C shape. When loading, the stainless steel sheet is clamped between the limit frames so that the center of the stainless steel sheet corresponds to the inner mold column to ensure the quality of processing.
