[0015] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0016] like Figure 1 As shown, it is a schematic diagram of the structure of the material blocking device of the screw heading machine provided by the utility model. The material blocking device of the screw heading machine is used to perform material blocking operations on a section of steel 10, so as to cut it into a suitable length. The material blocking device of the screw heading machine includes a body 20, a feeding assembly 30 arranged on the body 20, a clamping assembly 40 arranged on one side of the feeding assembly 30, and a material blocking assembly 50 arranged on one side of the clamping assembly 40. It can be imagined that the material blocking device of the screw heading machine also includes some other functional modules, such as a power module, a drive module, etc., which are technologies already known to those skilled in the art and will not be described one by one here.

[0017] The fuselage 20 is used to carry various module components. The shape of the fuselage 20 can be set according to actual needs and will not be described in detail here.

[0018] Please also read Figure 2 and Figure 3The feeding assembly 30 includes a plurality of guide wheels 31 disposed on one side of the body 20 , at least two wire wheels 32 disposed on one side of the guide wheels 31 , and a main mold base 33 disposed on one side of the wire wheel 32 .

[0019] The rotation direction of the guide wheel 31 is perpendicular to the rotation direction of the wire wheel 32. Two wire holes 34 are respectively provided on both sides of a plurality of the guide wheels 31. The steel material 10 passes through one of the wire holes 34 to complete the primary guidance, and passes through between a plurality of the guide wheels 31, thereby completing the correction and transportation of the steel material 10 in the horizontal direction. The steel material 10 passes through the second wire hole 34 to complete the secondary guidance, and passes between the two wire wheels 32, thereby completing the correction and transportation of the steel material 10 in the vertical direction.

[0020] The main die base 33 is provided with a guide hole 35 , and the steel material passes through the guide hole 35 and is clamped by the material clamping assembly 40 , so that the cutting and material transfer operation is performed.

[0021] The material clamping assembly 40 includes a tool clamp seat 41 and a tool clamp rod 42 rotatably disposed on one side of the tool clamp seat 41 .

[0022] The end of the tool clamp seat 41 facing the feeding assembly 30 is provided with a scissor shaft 43, and the end of the tool clamp rod 42 facing the scissor shaft 43 is provided with a tool clamp sheet 44. The tool clamp rod 42 is supported by a bracket 45. When clamping materials, the tool clamp rod 42 is lowered so that there is a material clamping gap between the scissor shaft 43 and the tool clamp sheet 44. The two sides of the steel 10 are respectively abutted between the scissor shaft 43 and the tool clamp sheet 44, thereby completing the material clamping operation. After cutting the steel 10, the material clamping assembly 40 will move under a driving module to complete the material transfer operation. The working principle of the material clamping assembly 40 is the existing technology. The specific clamping situation can refer to a tool clamp rod anti-shake device disclosed in Chinese patent CN201520791288.9.

[0023] The material blocking assembly 50 includes a rod seat 51 disposed on the body 20 , a material blocking rod 52 movably inserted through the rod seat 51 , a material blocking arm 53 disposed at one end of the material blocking rod 52 , and a material blocking screw 54 disposed at one end of the material blocking arm 53 .

[0024] The rod seat 51 is provided with a fixing screw hole 55, and the rod seat 51 and the material stopping rod 52 are fastened together by a fixing screw 56 which is screwed into the fixing screw hole 55. The position of the material stopping rod 52 in the rod seat 51 can be adjusted by screwing the fixing screw 56, thereby adjusting the position of the material stopping arm 53 to change the material stopping distance for coarse adjustment.

[0025] The blocking screw 54 is disposed at one end of the blocking arm 53 away from the blocking rod 52, and the end face of the blocking screw 54 faces the guide hole 35 on the main mold base 33, so that after the steel 10 extends out of the guide hole 35, it can be blocked by the blocking screw 54, thereby completing the blocking operation. By twisting the blocking screw 54, the distance between the blocking surface of the blocking screw 54 and the guide hole 35 is changed, thereby adjusting the slight blocking distance, and fine-tuning the blocking distance, so as to achieve control of the blocking distance accuracy and improve product quality.

[0026] Compared with the prior art, the material stopper device of the screw heading machine provided by the utility model accurately sends the steel 10 out of the guide hole 35 through the material feeding assembly 30, and the material clamping assembly 40 clamps the guide hole 35 of this part. The material stopper assembly 50 can roughly adjust the material stopper distance by adjusting the position of the material stopper rod 52 in the rod seat 51, and finely adjust the material stopper distance by twisting the material stopper screw 54, thereby realizing the control of the material stopper distance accuracy and improving product quality.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
