Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and more specifically to a cam-type drawing machine for stainless steel bars. Background Technology

[0002] Traditional cam-type drawing machines are widely used in the metal processing industry, especially in the cold drawing of stainless steel bars. However, existing cam-type drawing machines often suffer from problems such as complicated operation, long time consumption, and low efficiency when switching between drawing dies of different specifications. This is mainly due to the unreasonable design of the die fixing method, which leads to a cumbersome die replacement process and affects production efficiency and processing flexibility.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a cam-type drawing machine for stainless steel bars in order to achieve a more practical purpose. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cam-type drawing machine for stainless steel bars to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a cam-type drawing machine for stainless steel bars, comprising a cam-type drawing machine body, which consists of a frame, a drawing die, a drive system, and a clamp. The frame provides a stable support structure. The drawing die is used to control the shape and size of the material being drawn. The clamp firmly holds the material to be drawn. The drive system is used to drive the clamp to move for drawing operations. The cam-type drawing machine body also includes a quick-release mechanism for the die, which includes a die fixing seat with at least two mating slots. The bottom of the drawing die has a mating block that matches the mating slots. Positioning slots are opened on both sides of the drawing die. Two mounting bases are installed at the top of the die fixing seat. Each base has a cylinder, and a positioning pin is fixed inside the cylinder. The positioning pin is inserted into the positioning slot to lock the drawing die. The cylinder drives the positioning pin. The drawing die can be quickly unlocked by exiting the positioning slot. A quick-release mechanism for the die is added to the main body of the cam-type drawing machine. This mechanism consists of a die fixing seat, a docking slot, a docking block, a positioning slot, a mounting base, a cylinder, and a positioning pin. The die fixing seat is firmly installed on the frame. The docking slot matches the docking block at the bottom of the drawing die to achieve initial positioning. Positioning slots are designed on both sides of the drawing die. Corresponding to these slots are cylinders installed on the mounting base at the top of the die fixing seat. A positioning pin is fixed inside the cylinder. When the cylinder is working, the positioning pin can be precisely inserted into the positioning slot to achieve a firm lock on the drawing die. Conversely, when the cylinder is driven in the opposite direction, the positioning pin exits the positioning slot, achieving quick unlocking of the die for easy replacement. Through the automated control of the cylinder, the die replacement operation process is greatly simplified, reducing manual intervention and cumbersome tightening steps, and improving replacement efficiency.

[0006] Furthermore, the shapes of the docking groove, docking block, positioning groove, and positioning post can be designed as any one of cuboid, cylinder, or hexagonal prism.

[0007] Furthermore, two stabilizing guide plates are also installed on the mold fixing base. Each stabilizing guide plate has a through groove that matches the positioning post. Through the guiding effect of the stabilizing guide plates, the stability and accuracy of the drawing die during the installation process are enhanced.

[0008] Furthermore, the main body of the cam-type drawing machine also includes a cooling device, which is a cooling fan located around the drawing die. By circulating cooling gas, the heat generated during the drawing process is effectively dissipated, thereby maintaining the temperature of the drawing die and surrounding components within a reasonable range, improving the stability of the drawing operation and the quality of the material.

[0009] Furthermore, the main body of the cam-type drawing machine also includes a safety protection device, which includes, but is not limited to, an emergency stop button, an overload protection sensor, and a limit switch, to ensure that the machine can be stopped quickly in abnormal circumstances, protecting the safety of the equipment and operators.

[0010] Furthermore, the bottom of the frame is equipped with height-adjustable support feet, which facilitates adjusting the equipment height according to the specific conditions of the production site.

[0011] The technical effects and advantages of this utility model are:

[0012] This invention adds a quick-release mold mechanism to the main body of a cam-type drawing machine. This mechanism consists of a mold fixing seat, a docking groove, a docking block, a positioning groove, a mounting base, a cylinder, and a positioning pin. The mold fixing seat is securely mounted on the frame. The docking groove matches the docking block at the bottom of the drawing mold for initial positioning. Positioning grooves are designed on both sides of the drawing mold, corresponding to a cylinder mounted on the mounting base at the top of the mold fixing seat. A positioning pin is fixed inside the cylinder. When the cylinder operates, the positioning pin precisely inserts into the positioning groove, firmly locking the drawing mold. Conversely, when the cylinder reverses its direction, the positioning pin exits the positioning groove, quickly unlocking the mold for easy replacement. The automated control of the cylinder significantly simplifies the mold replacement process, reduces manual intervention and cumbersome tightening steps, and improves replacement efficiency.

Detailed Implementation

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0018] Example 1: This utility model provides a cam-type drawing machine for stainless steel bars, including a cam-type drawing machine body 100. The cam-type drawing machine body 100 consists of a frame 110, a drawing die 111, a drive system 112, and a clamp 113. The frame 110 provides a stable support structure. The drawing die 111 is used to control the shape and size of the material being drawn. The clamp 113 firmly clamps the material to be drawn. The drive system 112 is used to drive the clamp 113 to move and perform the drawing operation. The cam-type drawing machine body 100 also includes a die quick-release mechanism. The system includes a mold fixing base 114, which has at least two mating grooves 115. The bottom of the drawing mold 111 has a mating block 116 that matches the mating grooves 115. The drawing mold 111 has positioning grooves 117 on both sides. The top of the mold fixing base 114 is equipped with two mounting bases 118. Each base is equipped with a cylinder 119. A positioning pin 120 is fixed inside the cylinder 119. The positioning pin 120 is inserted into the positioning groove 117 to lock the drawing mold 111. The cylinder 119 drives the positioning pin 120 to exit the positioning groove 117 to quickly unlock the drawing mold 111.

[0019] A quick-release mechanism for the die is added to the main body 100 of the cam-type drawing machine. This mechanism consists of a die fixing seat 114, a docking groove 115, a docking block 116, a positioning groove 117, a mounting base 118, a cylinder 119, and a positioning column 120. The die fixing seat 114 is stably installed on the frame 110. The docking groove 115 matches the docking block 116 at the bottom of the drawing die 111 to achieve initial positioning. Positioning grooves 117 are designed on both sides of the drawing die 111, corresponding to the positioning grooves installed on the top of the die fixing seat 114. The cylinder 119 is mounted on the mounting base 118. A positioning pin 120 is fixed inside the cylinder 119. When the cylinder 119 is working, the positioning pin 120 can be precisely inserted into the positioning groove 117 to achieve a firm lock on the drawing die 111. Conversely, when the cylinder 119 is driven in the opposite direction, the positioning pin 120 is disengaged from the positioning groove 117 to achieve quick unlocking of the die and facilitate replacement. Through the automated control of the cylinder 119, the operation process of die replacement is greatly simplified, manual intervention and cumbersome fastening steps are reduced, and replacement efficiency is improved.

[0020] Example 2:

[0022] Two stabilizing guide plates 121 are also installed on the mold fixing base 114. Each stabilizing guide plate has a through groove that matches the positioning post 120. Through the guiding effect of the stabilizing guide plate 121, the stability and accuracy of the drawing die 111 during the installation process are enhanced.

[0023] To address the potential high temperatures generated during the drawing process, Embodiment 2 incorporates a cooling device within the main body 100 of the cam-type drawing machine. This cooling device, in the form of a cooling fan, is positioned around the drawing die 111 and effectively dissipates the heat generated during the drawing process by circulating cooling gas. This design helps maintain the temperature of the drawing die 111 and surrounding components within a reasonable range, preventing material performance degradation or equipment damage due to overheating, thereby improving the stability of the drawing operation and the quality of the material.

[0024] The cam-type drawing machine body 100 also includes safety protection devices, including but not limited to emergency stop buttons, overload protection sensors and limit switches, to ensure that the machine can be stopped quickly in abnormal situations, protecting the safety of the equipment and operators.
