Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a material blocking mechanism of a bending machine. Background Art

[0002] A bending machine is a machine that can bend thin plates. The material blocking mechanism of the bending machine is an important working mechanism used for bending positioning. Its main function is to control the feeding length of the plate to be processed and ensure that the plate is bent at the predetermined position.

[0003] The current bending mechanism is usually composed of an electric push rod and a baffle plate. The electric push rod is responsible for driving the baffle plate to move precisely as a power source. When bending, one end of the plate is fitted with the baffle plate, which can ensure that the plate is bent at a predetermined position. However, due to the long-term direct contact between the baffle plate and the plate, its surface will inevitably be worn. This wear will not only affect the fitting accuracy between the baffle plate and the plate, but also affect the stability and consistency of the bending effect, so that the entire baffle plate needs to be replaced regularly. The worn area on the baffle plate cannot be partially replaced, which greatly increases the production cost. Therefore, those skilled in the art provide a baffle mechanism for a bending machine to solve the problems raised in the above background technology.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model embodiment discloses a material blocking mechanism of a bending machine. Figure 1-3 A material blocking mechanism of a bending machine comprises a bottom plate 1, an L-shaped plate 2 is arranged on one side of the bottom plate 1, an electric push rod 3 is arranged on the L-shaped plate 2, a moving plate 4 is arranged at one end of the electric push rod 3, a plurality of mounting blocks 5 are arranged on the side of the moving plate 4 away from the electric push rod 3, a material blocking plate 6 is arranged on the mounting block 5 for positioning the plate, and a positioning mechanism 7 is arranged on the moving plate 4 for limiting and fixing the material blocking plate 6;

[0027] Reference Figure 2 and Figure 3 The positioning mechanism 7 includes two T-shaped rods 701, a pull plate 702, a positioning plate 703 and two springs 704. The two T-shaped rods 701 are symmetrically arranged on the same side of the moving plate 4, and the pull plate 702 is slidably arranged between the two T-shaped rods 701. The positioning plate 703 is arranged at one end of the pull plate 702 and passes through the moving plate 4. The bottom end of the positioning plate 703 contacts the upper end of the mounting block 5. The two springs 704 are respectively sleeved on the outer sides of the corresponding T-shaped rods 701, and the two ends of the spring 704 are respectively connected to the T-shaped rod 701 and the pull plate 702; a wedge-shaped groove 8 is provided on the side of the mounting block 5 away from the moving plate 4, and a wedge-shaped block 9 used in conjunction with the wedge-shaped groove 8 is provided on one side of the baffle plate 6, and the wedge block 9 is plugged into the wedge-shaped groove 8.

[0028] By adopting the above-mentioned technical solution, when the surface of the corresponding baffle plate 6 is worn, the staff can directly pull the pull plate 702 to move the positioning plate 703. At this time, the positioning plate 703 is moved away from the upper end of the mounting block 5, thereby canceling the limit on the wedge block 9, so that the staff can directly pull the baffle plate 6 upward to move the wedge block 9 out of the wedge groove 8, thereby facilitating the rapid replacement of the worn baffle plate 6 without replacing all the baffle plates 6, thereby greatly saving production costs.

[0029] Reference Figure 1 A distance measuring sensor 10 is provided at the lower end of one side of the movable plate 4 , and the side of the distance measuring sensor 10 away from the movable plate 4 is aligned with the inner side of the material blocking plate 6 .

[0030] By adopting the above technical solution, when the plate is bent, the electric push rod 3 works to push the movable plate 4 to the use position. The distance between the movable plate 4 and the bending seat can be accurately controlled by the distance measuring sensor 10. Then, one end of the plate is fitted with the inner side of the baffle plate 6, and the bending position of the plate can be accurately located, so that the plate can be bent at the predetermined position.

[0031] Reference Figure 1 The upper end of the bottom plate 1 is provided with two symmetrically distributed guide grooves 11, and the bottom end of the movable plate 4 is provided with two symmetrically distributed guide blocks 12. The bottom ends of the guide blocks 12 penetrate into the guide grooves 11 and are slidably connected with the guide grooves 11.

[0032] By adopting the above technical solution, when the movable plate 4 moves, the guide block 12 is driven to slide in the guide groove 11, thereby ensuring the stability of the movable plate 4 when moving.

[0033] Reference Figure 1 and Figure 2 , connecting blocks 13 are arranged around the outer side of the bottom plate 1, and mounting holes are opened on the connecting blocks 13.

[0034] By adopting the above technical solution, the base plate 1 can be conveniently installed on the bending machine through the installation holes on the connecting block 13 .

[0035] Working principle: When the utility model is in use, the electrical components appearing in the present application are all externally connected to the power supply and the control switch. First, the base plate 1 is installed on the bending machine through the mounting holes on the connecting block 13. When the plate is bent, the electric push rod 3 works to push the movable plate 4 to move to the use position. The distance measuring sensor 10 can be used to accurately control the movement of the movable plate 4 to the bending seat. Then, one end of the plate is fitted with the inner side of the baffle plate 6 at this time, and the bending position of the plate can be accurately positioned, so that the plate can be bent at the predetermined position. When the surface of the corresponding baffle plate 6 is worn, the staff can directly pull the pull plate 702 to move the positioning plate 703. At this time, the positioning plate 703 is moved away from the upper end of the mounting block 5, thereby canceling the limit on the wedge block 9, so that the staff can directly pull the baffle plate 6 up to move the wedge block 9 out of the wedge groove 8, thereby facilitating the rapid replacement of the worn baffle plate 6, without the need to replace all the baffle plates 6, which greatly saves production costs.

[0036] When the utility model is in use, it is convenient to accurately control the moving position of the baffle plate 6, so that the plate can be bent at a predetermined position, and it is convenient to quickly replace the worn baffle plate 6 without replacing all the baffle plates 6, which greatly saves production costs.
