Description

Technical Field

[0001] The invention relates to the technical field of plate processing, and in particular to a plate pushing device with a buffer brake structure. Background Art

[0002] CNC stamping technology for metal materials is one of the widely used technical means in mechanical manufacturing. The processed materials are mostly rectangular metal plates. At present, CNC stamping mostly refers to the stamping and feeding links being controlled by computers, while feeding is often done manually.

[0003] In order to improve efficiency and realize automatic control of the entire processing process, the matching automatic plate feeder has been widely used in recent years. Due to automatic feeding, the plate is often not accurately positioned when it falls on the feeder, that is, after the plate enters the feeder, when the plate is pushed, after the pushing device stops working, the plate continues to move a distance due to inertia, resulting in the position of the plate not being very accurate. It is necessary to add a positioning clamping device to ensure the continuity of the entire process.

[0004] At present, the commonly used positioning methods include photoelectric, electromagnetic suction cup, double cylinder positioning, etc., which have acceptable effects, but they also have their shortcomings, mainly because the structure or control is more complicated, and some methods are more expensive.

[0005] Therefore, it is necessary to develop a plate pushing device with a buffer brake structure to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a plate pushing device with a buffer brake structure which has a simple structure and accurate positioning.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a plate pushing device with a buffer brake structure, comprising:

[0008] A material placing plate, used for supporting the plate;

[0009] A pushing component, used for pushing the plate;

[0010] The buffer assembly includes a fixed plate and a reduction wheel installed on the fixed plate. A material feeding gap is formed between the fixed plate and the material placing plate. The reduction wheel extends into the material feeding gap and frictionally contacts with the surface of the plate extending into the material feeding gap.

[0011] Furthermore, the buffer assembly includes a control component, which includes a pressure block and a clamping bolt that presses the pressure block. The clamping bolt can squeeze the reduction wheel through the pressure block, and the reduction wheel penetrates into the material passing gap.

[0012] Furthermore, an elastic portion is provided between the pressing block and the clamping bolt, one end of the elastic portion abuts against the clamping bolt, and the other end of the elastic portion abuts against the pressing block.

[0013] Furthermore, the lower surface of the pressing block contacts the surface of the reduction wheel.

[0014] Furthermore, the buffer assembly includes a support seat, which is movably connected to the fixed plate and can move around the connection between the support seat and the fixed plate, and the reduction wheel is installed on the support seat.

[0015] Furthermore, the material placement plate has a pushing hole that passes through the upper and lower surfaces thereof, and the pushing assembly has a pushing claw, and the pushing claw moves along the pushing hole to push the plate.

[0016] Furthermore, a clamping assembly is provided on one side of the material placement plate, and the clamping assembly is used to clamp the plate.

[0017] Furthermore, the material placement plate has a through hole penetrating the upper and lower surfaces thereof, and the clamping assembly has a clamping rod, and the clamping rod moves along the through hole to clamp the plate.

[0018] Compared with the prior art, the beneficial effect of the utility model is that the utility model is a plate pushing device with a buffer brake structure, which has the characteristics of simple structure and precise positioning. By arranging a reduction wheel and a roller in the material passing gap, the reduction wheel and the roller frictionally reduce the upper and lower surfaces of the plate, so that the plate can accurately stay at the predetermined position, reducing the situation where the plate continues to move a distance due to inertia, thereby improving the precise positioning effect of the plate.

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] Please see Figures 1 to 4 The utility model is a plate pushing device with a buffer brake structure, which includes a flat plate 1, a material placing plate 2 installed on the flat plate 1, a clamping component 3 and a pushing component 4 arranged outside the material placing plate 2, and a buffer component 5 arranged opposite to the pushing component 4.

[0027] Please see Figure 1 The flat plate 1 is in a horizontal state and is used to carry the material placing plate 2, the clamping component 3, the pushing component 4 and the buffer component 5.

[0028] Please see Figure 1 The material placing plate 2 is installed on the upper surface of the flat plate 1 and is arranged parallel to the flat plate 1. A gap is maintained between the material placing plate 2 and the flat plate 1, and the gap can allow the clamping component 3 and the pushing component 4 to pass through.

[0029] The loading plate 2 has a plurality of through holes 21 penetrating its upper and lower surfaces. The through holes 21 extend from the edge of the loading plate 2 into the loading plate 2. The number and spacing of the plurality of through holes 21 can be changed according to demand. In this embodiment, the through holes 21 are spaced from one side of the loading plate 2 to the other side.

[0030] The material placement plate 2 also has push holes 22 running through its upper and lower surfaces. The number and spacing of the push holes 22 can be changed according to demand. In this embodiment, the push holes 22 are spaced from one end of the material placement plate 2 to the other end.

[0031] The through hole 21 and the push hole 22 are in a vertical relationship.

[0032] A baffle 23 is installed on the upper surface of the material placing plate 2 . The baffle 23 is perpendicular to the through hole 21 and is located outside the material pushing hole 22 . The baffle 23 is spaced from one end of the material placing plate 2 to the other end.

[0033] Please see Figure 1 to Figure 2 The clamping assembly 3 includes a clamping drive member 31, a transmission member 32 connected to the clamping drive member 31, and a clamping rod 33 installed on the transmission member 32. The clamping drive member 31 is installed on the upper surface of the plate 1. One end of the transmission member 32 is connected to the clamping drive member 31, and the other end extends to the bottom of the material placing plate 2 and a synchronous plate 34 is fixedly installed at the end. Slide rails 35 are provided on both sides of the transmission member 32. The slide rail 35 is installed on the upper surface of the plate 1, and one end of the slide rail 35 extends to the bottom of the material placing plate 2. A slider 36 is slidably connected to the slide rail 35. The synchronous plate 34 is fixedly connected to the slider 36. The clamping rod 33 is installed on the upper surface of the synchronous plate 34, and its bottom is fixedly connected to the synchronous plate 34. The top extends vertically upward through the through hole 21 and is located above the material placing plate 2. The clamping drive member 31 drives the clamping rod 33 to move along the through hole 21 toward the baffle 23 through the transmission member 32, so as to cooperate with the baffle 23 to clamp the two sides of the plate.

[0034] Please see Figure 1 and Figure 3 The pushing assembly 4 includes a pushing driving member 41, a pushing slider 42 driven by the pushing driving member 41, and a pushing claw 43 installed on the pushing slider 42. The pushing driving member 41 is installed on the upper surface of the flat plate 1 to drive the pushing slider 42 to enter the bottom of the material placing plate 2. The bottom of the pushing claw 43 is fixedly connected to the pushing slider 42, and the top of the pushing claw 43 extends vertically upward through the pushing hole 22. The pushing driving member 41 pushes the pushing claw 43 to move along the pushing hole 22 toward the buffer assembly 5 through the pushing slider 42.

[0035] Please see Figure 1 and Figure 4 The buffer assembly 5 includes a fixed plate 51 installed on the upper surface of the material placing plate 2, a reduction wheel 52 installed on the fixed plate 51, and a control member 53 arranged above the reduction wheel 52. A material passing gap 50 is formed between the fixed plate 51 and the material placing plate 2, and the material passing gap 50 is for the plate to pass through. The fixed plate 51 has a through hole 54 running through its upper and lower surfaces. The reduction wheel 52 is installed on a support seat 55, and the support seat 55 is movably connected to the fixed plate 51. The support seat 55 can move with the connection between the support seat 55 and the fixed plate 51 as the center, so that the reduction wheel 52 enters the through hole 54, extends into the material passing gap 50 or exits the through hole 54. Secondly, a roller 56 is installed on the material placing plate 2, and the roller 56 corresponds to the reduction wheel 52.

[0036] Preferably, the reduction wheel 52 is made of a material having a damping effect, such as rubber.

[0037] Please see Figure 4 The control member 53 includes a pressing block 531 and a clamping bolt 532 for pressing the pressing block 531. The lower surface of the pressing block 531 contacts the surface of the reduction wheel 52. The clamping bolt 532 is arranged above the pressing block 531 and can move vertically downward to squeeze the reduction wheel 52, so that the distance between the reduction wheel 52 and the roller 56 is reduced to adapt to plates of different thicknesses. An elastic part 533 is provided between the pressing block 531 and the clamping bolt 532. One end of the elastic part 533 presses against the clamping bolt 532, and the other end presses against the pressing block 531.

[0038] When the plate pushing device with a buffer brake structure of the utility model is in use, the clamping driving member 31 drives the clamping rod 33 to move along the through hole 21 toward the baffle 23 through the transmission member 32, and is used to cooperate with the baffle 23 to clamp the two sides of the plate. The pushing driving member 41 pushes the plate to move along the pushing hole 22 toward the buffer component 5 through the pushing claw 43. When it is about to move to the predetermined position, the pushing claw 43 stops pushing the plate. At this time, one end of the plate enters the feeding gap 50, and the spacing between the reduction wheel 52 and the roller 56 is smaller than the feeding gap 50. The upper and lower surfaces of the plate are clamped by the reduction wheel 52 and the roller 56, and friction deceleration is performed to make the plate accurately stay at the predetermined position.

[0039] The utility model is a plate pushing device with a buffer brake structure, which has the characteristics of simple structure and precise positioning. By arranging a reduction wheel and a roller in the material passing gap, the reduction wheel and the roller perform friction deceleration on the upper and lower surfaces of the plate, so that the plate can accurately stay at a predetermined position, reducing the situation where the plate continues to move a distance due to inertia, and improving the precise positioning effect of the plate.
