Description

Technical Field

[0001] The utility model belongs to the technical field of automatic feeding, and in particular relates to an automatic feeding connecting rod structure for a punching machine. Background Art

[0002] The punch press is driven by the main motor, which drives the flywheel, and through the clutch drives the gear, crankshaft (or eccentric gear) and connecting rod to achieve the linear motion of the slider;

[0003] At present, there are two common feeding methods for punch presses, one is manual feeding and the other is automatic feeding. Manual feeding is slow but stable, while automatic feeding is efficient, but it may cause the machine to stop when a fault occurs, so both have their advantages and disadvantages.

[0004] In the automated feeding structure, a conveyor belt is usually used in combination with a pushing mechanism for feeding. However, since the pushing mechanism has to perform multiple actions, it requires multiple power components and a relatively complex structure, which results in high production costs and is not conducive to production and subsequent maintenance. Utility Model Content

[0005] In view of the problems raised by the above background technology, the purpose of the utility model is to provide an automatic feeding connecting rod structure for a punch press.

[0006] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0007] A punch press automatic feeding connecting rod structure, including a base, the base is equipped with a rebound box, the rebound box is provided with a limit groove, a lifting block is slidably installed in the limit groove, a first rebound member is installed between the bottom of the lifting block and the bottom of the limit groove, the lifting block is slidably installed with a rack, the rack is respectively equipped with a push plate and a return plate on both sides of the base, a second rebound member is connected between the return plate and the rebound box, an L-shaped support plate is installed on the base, the L-shaped support plate is threadedly connected to a limit screw, a motor is installed on the base, and a half gear meshing with the rack is connected to the output end of the motor.

[0008] It is further defined that both the first resilient member and the second resilient member are springs. Such a design is common and cheap, has good economical efficiency, and is easy to replace as spare parts.

[0009] It is further defined that the push plate is installed with a resistance plate in an adjustable position, and such a design can adapt to the contact and push of workpieces of different thicknesses.

[0010] It is further defined that the bottom of the base is provided with height-adjustable support feet, and such a design is adapted to the docking of punching equipment of different heights.

[0011] It is further defined that the push plate and the return plate are both slidably mounted on the rack, and the push plate and the return plate are both threadedly connected with locking screws. This design facilitates the adjustment and fixation of the positions of the push plate and the return plate.

[0012] The beneficial effects of adopting the utility model are:

[0013] With the structural design of the utility model, the only power component is the motor, so the production cost is low and the economy is good;

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 to Figure 4As shown, the utility model provides an automatic feeding connecting rod structure for a punch press, comprising a base 1, a rebound box 2 is installed on the base 1, the rebound box 2 is provided with a limiting groove 3, a lifting block 4 is slidably installed in the limiting groove 3, a first rebound component 5 is installed between the bottom of the lifting block 4 and the bottom of the limiting groove 3, a rack 6 is slidably installed on the lifting block 4, a push plate 7 and a return plate 8 are respectively installed on both sides of the base 1, a second rebound component 9 is connected between the return plate 8 and the rebound box 2, an L-shaped support plate 10 is installed on the base 1, the L-shaped support plate 10 is threadedly connected with a limiting screw 11, a motor 12 is installed on the base 1, and a half gear 13 meshing and matching with the rack 6 is connected to the output end of the motor 12.

[0024] In this embodiment, when using a punch press automatic feeding connecting rod structure, the conveyor belt and the punch press are connected as follows: Figure 4 The method in the above method is used for docking;

[0025] The material is moved from the conveyor belt to the front side of the push plate 7 and stops. The motor 12 drives the half gear 13 to rotate, thereby driving the rack 6 to slide forward in the lifting block 4. The push plate 7 moves forward, and the second rebound member 9 is compressed by the return plate 8, thereby achieving the purpose of pushing and loading the material.

[0026] When the half gear 13 rotates to the side without teeth, the upper side of the rack 6 is not interfered, so under the effect of the first rebound member 5, the lifting block 4 will drive the rack 6 to rise, and at the same time, under the effect of the second rebound member 9, the rack 6 returns to its position and stops after being limited by the limit screw 11. The rack 6 first rises and then retreats, which will not interfere with the material delivered to the place by the subsequent conveyor belt after the pushing is completed. The conveyor belt can continue to feed the material synchronously while the pushing is in progress, thereby ensuring efficiency.

[0027] This reciprocating process realizes cyclical automatic loading.

[0028] Preferably, both the first resilient member 5 and the second resilient member 9 are springs. Such a design is common, cheap, economical, and easy to replace with spare parts. In fact, the selection of the first resilient member 5 and the second resilient member 9 can also be considered according to specific circumstances.

[0029] Preferably, the push plate 7 is installed with a resistance plate 14 in an adjustable position. Such a design can adapt to the contact and pushing of workpieces of different thicknesses. In fact, the installation method of the resistance plate 14 can also be considered according to specific circumstances.

[0030] Preferably, a height-adjustable support foot 15 is installed at the bottom of the base 1. Such a design is suitable for docking punching equipment of different heights. In fact, the selection of the support foot 15 can also be considered according to specific circumstances.

[0031] Preferably, the push plate 7 and the return plate 8 are both slidably mounted on the rack 6, and the push plate 7 and the return plate 8 are both threadedly connected with locking screws 16. This design facilitates the adjustment and fixation of the positions of the push plate 7 and the return plate 8. In fact, the installation method of the push plate 7 and the return plate 8 can also be considered according to specific circumstances.

[0032] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
