Description

Technical Field

[0001] This invention relates to the field of metal processing technology, specifically to a press for contact processing. Background Technology

[0002] Contacts are one of the key components of switching devices. Based on their structure and operating characteristics, they can be divided into three categories: breakable contacts, sliding contacts, and fixed contacts. Contacts are made from metals with good electrical conductivity. The processing of contacts is essentially metal processing, with forging and drilling being the most common procedures.

[0003] Forging presses are used to change the shape of contact materials during forging. The forging process for stationary contacts involves pressing an inner hole into an aluminum rod. Typical forging presses have welded steel plates for the machine body, resulting in good rigidity. The slide uses a six-sided rectangular track for high precision and employs a wet pneumatic grinding clutch. The main gear is in an oil bath, ensuring smooth movement and low noise.

[0004] A typical forging press usually uses a hydraulic cylinder as a power source to drive the lower pressure head assembly to press down onto the surface of the workpiece on the worktable to achieve the pressing effect. For metal parts that are large in size and have a regular shape, the accuracy requirements for manual placement are not too strict. However, for aluminum round bars, which are the raw materials for stationary contacts, not only are they small in size, but they also have a circular cross-section. When placing them manually, it is difficult to align them with the pressure head if they need to be placed upright, and if they need to be placed horizontally, they may roll. This requires the operator to manually support the workpiece in the early stages of pressing, which is not only time-consuming and laborious, but also poses a certain degree of danger. Summary of the Invention

[0005] The purpose of this invention is to provide a press for contact processing to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a press for contact processing, comprising a press body, an auxiliary positioning mechanism, a cleaning mechanism, and a control module, wherein the auxiliary positioning mechanism and the cleaning mechanism are disposed on the press body, the auxiliary positioning mechanism includes an infrared ranging module and a round bar positioning component, suitable for assisting in the positioning of round bar materials, and can meet both vertical and horizontal pressing requirements, the cleaning mechanism is suitable for surface dust removal of the pressed workpiece and removing debris generated during pressing, and the control module is electrically connected to each structure and is suitable for controlling the material pressing process.

[0007] Furthermore, the press body is composed of a hydraulic cylinder, a piston module, a guide module, a press head module, and a pressing table. The guide module is fixed on the pressing table, and the hydraulic cylinder, piston module, and press head module are arranged on the guide module and connected in sequence. The hydraulic cylinder is adapted to drive the press head module to move up and down with the assistance of the guide module through the piston module.

[0008] Furthermore, the infrared ranging module is installed on the pressure head module and includes multiple infrared rangefinders that are staggered to determine the distance between the pressure head module and the pressing table. The round bar positioning component is set on the pressing table for positioning and limiting the round bar.

[0009] Furthermore, the circular bar positioning assembly includes several sliders of different specifications and telescopic rods connected to them. Sliders of the same specifications can form a ring, which extends out of the pressing table surface under the drive of the telescopic rod. When the telescopic rod is retracted, each slider is flush with the pressing table surface.

[0010] Furthermore, the cleaning mechanism consists of a dust removal component and a drive component. The dust removal component is disposed on the pressing table, located on one side of the round bar positioning component, and connected to the drive component. The drive component is fixed on both sides of the round bar positioning component and is adapted to drive the dust removal component to move towards the round bar positioning component.

[0011] Furthermore, the dust removal assembly includes a suction pipe, a dust collection box, and an air extraction pipe. The suction pipe has a U-shaped structure with several through holes on its opposite sides and is internally connected to the dust collection box. The air extraction pipe is connected to the dust collection box and externally connected to an air extraction device.

[0012] Furthermore, the specific methods are as follows:

[0013] S1. Limiting: The control module calculates the required downward movement distance of the pressing head module to reach the surface of the round bar based on the diameter and placement of the round bar to be pressed, and selects an appropriate positioning and limiting method to start the round bar positioning component.

[0014] S2, Press head positioning: After the round bar is placed in place, the control module will command the hydraulic cylinder to move the press head module down to the surface of the round bar according to the pre-calculated distance to the surface of the round bar, and then command the round bar positioning component to reset to release the limit.

[0015] S3, Pressing: The control module drives the press body to complete the round bar pressing process and then resets.

[0016] S4. Dust removal of pressed products: The control module starts the cleaning mechanism, and the drive component moves the dust removal component to the pressed product. The external air extraction equipment is started to vacuum the pressed product body and its surroundings to remove debris and impurities that may be generated during pressing. At the same time, the round bar positioning component can be started to help turn the pressed product to improve the dust removal quality.

[0017] S5. Pressed product recycling: After dust removal, the pressed products are recycled.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: by setting an auxiliary positioning mechanism, it can meet the positioning and limiting effects of both vertical and horizontal pressing of round bar materials, reduce the error rate of manual positioning calibration, avoid potential dangers, and save manpower and time; by setting a cleaning structure, the pressed products can be dusted, and the round bar positioning component in the auxiliary positioning mechanism can contact all surfaces of the pressed products, thus improving the overall cleaning quality.

[0026] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] As shown in the figure, the present invention provides a technical solution: a press for contact processing, comprising a press body 1, an auxiliary positioning mechanism 2, a cleaning mechanism 3, and a control module. The auxiliary positioning mechanism 2 and the cleaning mechanism 3 are disposed on the press body 1. The auxiliary positioning mechanism 2 includes an infrared ranging module 21 and a round bar positioning component 22, which is suitable for assisting in the positioning of round bar materials and can meet the needs of both vertical and horizontal pressing. The cleaning mechanism 3 is suitable for removing dust from the surface of the pressed workpiece and removing debris generated during pressing. The control module is electrically connected to each structure and is suitable for controlling the material pressing process.

[0028] The press body 1 consists of a hydraulic cylinder 11, a piston module 12, a guide module 13, a press head module 14, and a pressing table 15. The guide module 13 is fixed on the pressing table 15. The hydraulic cylinder 11, the piston module 12, and the press head module 14 are arranged on the guide module 13 and connected in sequence. The hydraulic cylinder 11 is adapted to drive the press head module 14 to move up and down with the assistance of the guide module 13 through the piston module 12.

[0029] The infrared ranging module 21 is installed on the pressing head module 14 and may contain multiple infrared rangefinders, which are staggered and suitable for positioning the distance between the pressing head module 14 and the pressing table 15. The round bar positioning component 22 is set on the pressing table 15 and is used for positioning and limiting the round bar 4.

[0030] The round bar positioning assembly 22 includes several sliders 221 of different specifications and telescopic rods 222 connected thereto. Sliders 221 of the same specifications can form a ring and extend out of the surface of the pressing table 15 under the drive of the telescopic rods 222. When the telescopic rods 222 are retracted, each slider 221 is flush with the surface of the pressing table 15.

[0031] The cleaning mechanism 3 consists of a dust removal component 31 and a drive component 32. The dust removal component 31 is set on the pressing table 15, located on one side of the round bar positioning component 22, and connected to the drive component 32. The drive component 32 is fixed on both sides of the round bar positioning component 22 and is suitable for driving the dust removal component 31 to move towards the round bar positioning component 22.

[0032] The dust removal component 31 includes a suction pipe 311, a dust collection box 312, and an air extraction pipe 313. The suction pipe 311 has a U-shaped structure with several through holes on its opposite sides and is internally connected to the dust collection box 312. The air extraction pipe 313 is connected to the dust collection box 312 and is externally connected to an air extraction device.

[0033] The specific implementation method is as follows:

[0034] S1. Limiting: The control module calculates the required downward movement distance of the pressing head module 14 to reach the surface of the round bar 4 based on the diameter of the round bar 4 to be pressed and the placement method, and selects an appropriate positioning and limiting method to start the round bar positioning component 22.

[0035] S2, Press head positioning: After the round bar 4 is placed in place, the control module will command the hydraulic cylinder 11 to move the press head module 14 down to the surface of the round bar 4 according to the pre-calculated distance to the surface of the round bar 4, and then command the round bar positioning component 22 to reset to release the limit.

[0036] S3, Pressing: The control module drives the press body 1 to complete the pressing process of the round bar 4 and then resets.

[0037] S4. Dust removal of pressed products: The control module starts the cleaning mechanism 3, and the drive component 32 drives the dust removal component 31 to move to the pressed product. The external air extraction equipment is started to perform dust removal on the pressed product body and its surroundings to remove debris and impurities that may be generated during pressing. At the same time, the round bar positioning component 22 can be started to help turn the pressed product to improve the dust removal quality.

[0038] S5. Pressed product recycling: After dust removal, the pressed products are recycled.

[0039] Specifically, the distance calculation method in S1 is as follows: set the distance between the infrared ranging module 21 and the pressing head part of the pressing head module 14 as x, the distance between the infrared ranging module 21 and the pressing table 15 as X, the diameter of the round rod 4 as D, and the length as L. If the round rod 4 is placed vertically, the actual downward distance required for the pressing head module 14 to reach the surface of the round rod 4 is (XxL); if the round rod 4 is placed horizontally, the actual downward distance required for the pressing head module 14 to reach the surface of the round rod 4 is (XxD).

[0040] The method for selecting the limiting method for the round bar 4 is as follows: If the round bar 4 needs to be pressed vertically, then select the slider 221 group that is closest to the diameter D of the round bar 4 and has an inner diameter greater than D, raise it to form a complete ring, and place the round bar 4 in it (e.g., Figure 5 As shown on the left), because the round bar positioning component 22 is set to correspond to the pressure head module 14, it can also achieve the positioning effect without manual alignment and correction; if the round bar 4 needs to be pressed horizontally, then select the slider 221 group whose distance at the quarter notch is closest to D according to the diameter D of the round bar 4, raise the two opposing sliders 221, and place the round bar 4 between them (as shown on the left). Figure 5 As shown on the right, the round bar 4 will not roll around due to the restriction of the sliders 221 on both sides, thus avoiding the need for manual positioning.

[0041] In S2, due to the limiting effect of the slider 221 in S1, the pressing head module 14 should be able to touch the surface of the round bar 4 when it reaches the specified downward movement distance. At this time, the round bar 4 is also restricted. If the round bar positioning component 22 is reset, the round bar 4 will not move, thus avoiding affecting the deformation of the round bar 4 during subsequent pressing.

[0042] The auxiliary method in S4 is as follows: the control module can make each slider 221 of the round bar positioning component 22 rise and fall randomly to lift the pressed product on the upper side, and the dust removal component 31 can clean each surface of the pressed product, thus improving the dust removal quality.

[0043] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features, and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
