Description

Technical Field

[0001] The utility model relates to the technical field of punching equipment, in particular to a punching machine fixing bracket. Background Art

[0002] A punching machine is a mechanical device that installs raw materials, drives the power mechanism, and acts on the material with a punching die to complete the punching. The punching machine can perform operations such as sheet processing, stamping, molding, embossing, etc. to force metal into the die. In modern industrial production, the punching machine is a key equipment for modern processing of various types of holes. With the development of high-tech, the application field of the punching machine is becoming more and more extensive. According to the shape of the processed material, the punching machine is divided into flat punching machine, round tube punching machine, square tube punching machine and U-shaped steel punching machine.

[0003] Since the punching machine has only been developed for less than 20 years, and has only been developed in China for more than ten years, there are still many imperfections. In the existing technology, when punching stainless steel round tubes and square tubes, portable small punching machines are mostly used. Since the punching of stainless steel tubes must ensure that the steel tubes are horizontal or at a fixed angle, the quality of the steel tube punching directly determines the quality of the steel tube welding, and finally determines the quality and linearity of the finished product. Small punching machines only use manual handheld punching machines or manual auxiliary fixed profiles, and the horizontality is difficult to grasp, resulting in non-standard steel tube cutting. In addition, small punching machines are relatively light and prone to tilting or shaking during the punching process, which brings inconvenience and safety hazards to operators. Summary of the invention

[0004] In view of this, the purpose of the utility model is to provide a punching machine fixing bracket which is convenient for adjusting the horizontal angle and can stabilize the state of the punching machine to prevent it from tipping over when in use.

[0013] Furthermore, the first hinge hole and the first adjustment hole on the base mounting plate do not interfere with the threaded through holes that penetrate the base mounting plate from top to bottom.

[0014] Beneficial effect: It prevents the moving path of the adjusting rod from being blocked by the fixing part in the threaded through hole when the adjusting rod is moved, avoids the additional action of disassembling and assembling the adjusting rod, ensures that the angle can be changed by moving the adjusting rod alone, and makes the bracket more convenient to use.

[0015] Furthermore, the articulated shaft and the adjusting rod are screw rods, and the connecting piece is a nut adapted to the screw rod thread.

[0016] Beneficial effects: The material is simple and easy to manufacture, the screw itself can not only meet the conventional rod function, but also can be locked in position by screwing the nut.

[0017] Furthermore, the second adjustment hole of the support has an opening above the front and rear side walls of the support, and the first adjustment hole of the base mounting plate is a long hole, the length direction of the long hole extends along the left and right direction of the base mounting plate, and the adjustment rod passing through the front and rear can move in the long hole along the length direction of the long hole.

[0018] Beneficial effect: the rotation angle of the base mounting plate is not limited by the second adjustment hole, the adjustment space of the horizontal angle is expanded, and more inclination angles of the base mounting plate are increased.

[0021] Furthermore, above the front and rear side walls of the support, a plurality of modular holes with openings facing upward are sequentially opened from the opening of the second adjustment hole toward the second hinge hole, and the adjustment rod can be inserted into the modular holes.

[0022] Beneficial effect: When the adjusting rod is located on the front and rear side walls of the support, the adjusting rod is limited, and the connecting piece is used to further fix the position of the adjusting rod during the punching operation to prevent the adjusting rod from sliding on the front and rear side walls of the support after being subjected to force.

[0023] Furthermore, a rubber pad is fixed in the hole wall of the modular hole with the opening facing upward.

[0024] Beneficial effect: The rubber pad acts as a buffer during punching operation, reducing direct impact force and alleviating the overall vibration generated during punching machine operation.

[0025] Furthermore, the cross-sectional shape of the modular hole is semicircular.

[0026] Beneficial effects: convenient for processing and manufacturing.

[0027] Furthermore, reinforcing rods are arranged between adjacent legs.
