Description

Technical Field

[0001] This utility model belongs to the field of shearing technology, specifically, it relates to a shearing device for manufacturing distribution boxes. Background Technology

[0002] A distribution box is a box-like structure used to house electrical components. In its manufacturing process, it utilizes a shearing machine for sheet metal processing. A shearing machine is generally a machine that uses one blade to reciprocate linearly relative to another blade to shear sheet metal. It employs a moving upper blade and a fixed lower blade, with a suitable blade gap, to apply shearing force to metal sheets of various thicknesses, causing the sheet metal to break and separate to the required dimensions.

[0003] Chinese Patent Publication No. CN221184908U discloses a shearing device for manufacturing distribution boxes, including a shearing machine for distribution box manufacturing. The bottom of the shearing machine is fixedly connected to a base plate. A raw material sheet is passed through two conveying rollers on one side and extends into the shearing machine from the inlet. Then, a hydraulic push rod is activated to move two lifting plates relative to each other, causing the two conveying rollers to move relative to each other. This causes the anti-slip sleeves on the outer sides of the two conveying rollers to contact the top and bottom surfaces of the raw material sheet. When the drive motor and reducer are activated to rotate the transmission rod, the rotation of the transmission rod causes the square-hole tube to rotate. The meshing of the transmission bevel gear and the driven bevel gear drives the rotating shaft to rotate, which in turn drives the conveying rollers to rotate. The anti-slip sleeves allow the raw material sheet to be conveyed to the right, thus achieving automatic material feeding. The aforementioned prior art cannot adjust the spacing between the conveying rollers and can only convey sheets of a single thickness, limiting the overall applicability of the device.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a shearing device for manufacturing distribution boxes, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A shearing device for manufacturing distribution boxes includes a shearing cabinet and a support frame. The shearing cabinet has a feed inlet on its front side, the support frame has a sliding groove inside its side, a slider is embedded in the sliding groove, a rotating shaft is installed through the center of the slider, a guide roller is sleeved on the surface of the rotating shaft, a guide roller motor is provided on the outside of the rotating shaft, and internal screws are installed vertically through both sides of the slider.

[0008] Optionally, the inner screw is fitted with a threaded sleeve on the top surface of the bracket, and a belt is fitted onto the surface of the threaded sleeve. A lifting motor is provided on the top of the bracket near both sides, and an output shaft is provided at the bottom of the lifting motor.

[0009] Optionally, a secondary screw is rotatably mounted on the left side of the slider, the secondary screw has a handle at its top and a support plate at its bottom.

[0010] Optionally, an inner groove is formed at the center of both sides of the sliding groove, and a protrusion is fixedly connected to both ends of the slider at the position corresponding to the inner groove.

[0011] Optionally, the diameter of the holes on both sides of the slider is different from the diameter of the hole at another slider location.

[0012] Optionally, the surface of the guide roller is made of rubber with a high coefficient of friction.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0014] 1. The shearing device for manufacturing distribution boxes uses a handle to rotate, causing the auxiliary screw to engage with the inner thread of the slider. This allows the bottom support plate to lift the lower slider, thereby shortening the distance between the two sliders and reducing the gap between the two guide rollers. This makes it easier for narrower plates to fit the guide rollers and enter the shearing cabinet. Reverse rotation of the auxiliary screw can lower the lower slider, thereby widening the gap and allowing thicker plates to be inserted and conveyed. This improves the device's applicability to plates of different thicknesses.

[0015] 2. The shearing device for manufacturing the distribution box controls the rotation of two internal screws through a top lifting motor. The meshing of the internal screws and the threaded holes of the slider drives the upper slider to move in the sliding groove, thereby adjusting the height of the two guide rollers in front of the feed inlet. This changes the position of the plate inserted into the shearing cabinet for plates of different thicknesses, thus improving the shearing effect.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-5 As shown, this embodiment provides a shearing device for manufacturing distribution boxes, including: a shearing cabinet 1 and a support 2.

[0029] like Figure 1-5 As shown, the shearing cabinet 1 in this embodiment has a feed inlet 101 on the front, and a sliding groove 201 is provided inside the side of the bracket 2. A sliding block 202 is embedded in the sliding groove 201. A rotating shaft 213 is installed through the center of the sliding block 202. A guide roller 203 is sleeved on the surface of the rotating shaft 213. A guide roller motor 204 is provided on the outside of the rotating shaft 213. Internal screws 205 are vertically installed through both sides of the sliding block 202. The guide roller 203 on the bracket 2 is provided at both the top and bottom. The two ends of the rotating shaft 213 in each guide roller 203 are on the bracket. A slider 202 is provided in the sliding groove 201 of 2. It is installed by the internal screw 205 passing through the threaded hole on the slider 202. The center of the two guide rollers 203 is left with a gap, which is aligned with the feed port 101, so that the plate can pass through the gap and then through the feed port 101 and finally enter the shearing cabinet 1. The guide rail motor 204 drives the rotating shaft 213 to rotate, thereby driving the guide rollers 203 to rotate. The upper and lower guide rollers 203 rotate in opposite directions, and the outer plate is sent out towards the feed port 101 through the friction of the contact surface, thus performing the conveying operation.

[0030] like Figure 5 As shown, in this embodiment, an inner screw 205 is fitted with a screw sleeve 206 on the top surface of the bracket 2, and a belt 207 is fitted onto the surface of the screw sleeve 206. A lifting motor 208 is located near both sides of the top of the bracket 2, and an output shaft 209 is located at the bottom of the lifting motor 208. The inner screw 205 on both sides of the sliding groove 201 of the bracket 2 rotates to engage its surface threads with the threads of the slider 202, allowing the slider 202 to move up and down to adjust the position of the plate entering the feed inlet 101. The top is supported... The output shaft 209 of the lifting motor 208 points downwards, and two threaded sleeves 206 are fitted on the output shaft 209, arranged separately at the top and bottom. Similarly, threaded sleeves 206 are also provided on the inner screws 206 on both sides. The threaded sleeves 206 on the output shaft 209 and the threaded sleeves 206 on the inner screws 206 are connected by a belt 207. The rotation of the output shaft 209 driven by the lifting motor 208 causes the threaded sleeves 206 to drive the inner screws 206 on both sides through the belt 207, thereby realizing the function of adjusting the height of the slider 202.

[0031] like Figure 3 As shown, in this embodiment, a secondary screw 210 is rotatably mounted on the left side of the slider 202. A handle 212 is provided at the top of the secondary screw 210, and a support plate 211 is provided at the bottom of the secondary screw 210. The sliders 202 on both sides of the guide roller 203 are of different sizes; the slider 202 on the left is larger and extends from the sliding groove 201. The upper slider 202 has a threaded hole vertically penetrating it. The secondary screw 210 passes through the upper slider 202 and simultaneously passes directly through the light hole of the lower slider 202, connecting the two sliders. The square slider 202 is supported by the support plate 211 fixedly connected to the bottom of the auxiliary screw 210. The operator holds the top handle 212 and rotates the auxiliary screw 210 to adjust the height of the auxiliary screw 210 on the slider 202. At the same time, it drives the lower slider 202 to move, thereby adjusting the gap between the two sliders 202. Ultimately, this changes the gap size between the guide rollers 203, ensuring that for plates of different thicknesses, the upper and lower guide rollers 203 can fit against the surface of the plate for fixation when inserted, making its application range wider.

[0032] like Figure 4 As shown, the sliding groove 201 in this embodiment has an inner groove at the center of both sides, and the slider 202 has protrusions fixedly connected at both ends corresponding to the inner groove positions; wherein, the protrusions on both sides of the slider 202 are embedded in the inner groove, so that the slider 202 is installed in the sliding groove 201, and the slider 202 drives the guide roller to move up and down by rotating the inner screw 205, preventing the slider 202 from falling out of the sliding groove 201.

[0033] like Figure 2As shown, the diameter of the holes on both sides of the slider 202 in this embodiment is different from the diameter of the hole in the other slider 202. The hole in the lower slider 202 is a smooth hole, and its diameter is larger than the threaded hole in the upper slider 202. In this way, when the inner screw 205 rotates, it will only drive the upper slider 202 to move, while the lower slider 202 will move in coordination with the movement of the upper slider 202 and the pulling of the auxiliary screw 210. The inner screw 205 and the auxiliary screw 210 are distributed to adjust the sliders 202 at different heights, so as to achieve separate adjustment of the spacing and height.

[0034] like Figure 1 As shown, the surface of the guide roller 203 in this embodiment is made of rubber with a high coefficient of friction. The guide roller 203 rotates to squeeze and rotate the sheet material, thereby pushing the sheet material forward. The guide roller 203 needs to generate a large frictional force with the sheet material to automatically push the sheet material forward and transport it to the feed port 101 for feeding.

[0035] Working principle: The guide roller 203 is connected to the guide roller motor 204 through the intermediate rotating shaft 213. The guide roller motor 204 drives the rotating shaft 213 to rotate. The two guide rollers 203 rotate in opposite directions to push the plate clamped in the middle forward, through the feed port 101 and into the shearing cabinet 1 for processing. For plates of different thicknesses, by turning the handle 212, the upper slider 202 moves up or down through threaded engagement. The lower slider 202 is raised or lowered by the bottom support plate 211, thereby adjusting the gap between the two guide rollers 203, so that the device can feed plates of different thicknesses. In addition, the lifting motor 208 drives the two inner screws 205 to rotate. The inner screws 205 drive the upper slider 202 to move in the sliding groove 201, realizing the height adjustment of the entire device, thereby adjusting the height of the plate entering the feed port 101. The blade position is adjusted according to the plate of different thicknesses for faster and safer cutting.
